    Full Text Available Carcinoma of the breast is one of the commonest cancers occurring in female and accounts for 1/3rd of all the malignant diseases occurring in them. It is mainly a disease of the developed countries and accounts for 1,00,000 deaths annually. Breast carcinoma is classified as Early breast cancer, Locally advanced breast cancer and Metastatic breast cancer. By definition early stage breast cancer constitutes breast tumors of clinical stages I, IIa and T2N1M0. Early breast cancer is the one diagnosed by mammography. Women when approaches at this stage, they can go for breast conservation surgery. Not all women are candidates for this approach, and some require mastectomy as part of their treatment. AIM To observe the incidence of early breast carcinoma with particular reference to the time taken by the patients to seek medical advice after the symptoms have developed i.e. the average time taken by the patients to seek medical advice, their appropriate management and prognosis. MATERIALS AND METHODS This prospective study was conducted over a period of 2 years from Oct-2012 to Oct-2014 in 30 female patients aged between 25-65 years who were presented with lump in breast of size ≤5cms with or without pain, with or without lymph nodes to the outpatient department. All the patients were thoroughly asked about history, examined clinically, investigated, staged and managed by surgery either Breast Conservation Surgery or Modified Radical Mastectomy. Postoperative complications were recorded and followed up regularly. RESULTS The incidence of early breast cancer in this study was 0.98% with peak age incidence between 40-60 years and duration of symptoms <6 months in 18 patients. Breast Conservation Surgery + axillary dissection + Radiotherapy was done in 23%. Prognosis was good in these patients with no local recurrence and death. CONCLUSION The prognosis of early stage breast carcinoma patients in this study was good. To have long term tumor free and

    The squamocellular carcinoma is a malignant neoplasm commonest in the buccal cavity. The more frequently involved anatomical sites are the lower lip, the tongue's lateral edges and the mouth floor. Its etiology is multifactor although it is closely related to smoking and alcoholism. Clinical picture is generally characterized by the presence of different types of white, erythematous, between erythematous and white plaques, ulcers with raised edges and exophytic masses. Treatment includes surgical removal, radiotherapy, chemotherapy or both. In present paper the case of a man aged 70 presenting with buccal squamous carcinoma describing the clinical, and the histopathologic findings and its corresponding treatment. The early and appropriate diagnosis allowed the cure of this case. (author)

    A group of patients with clinical stage I or II squamous cell cervical carcinoma have been examined using a 1.5-T magnet. Of these, six have had radical hysterectomy (by April 1986), providing specimens for pathologic correlation. In this preliminary group of patients, MR imaging gave a more accurate assessment of primary tumor extent than did clinical staging. In three of six patients, the disease was underestimated clinically at examination under anesthesia. These patients would have been managed with preoperative radiation rather than surgery alone if the investigative MR imaging information had been used in treatment planning. CT examinations of these patients did not contribute useful information for patient management. Preoperative MR imaging has the potential to alter patient treatment in early cervical carcinoma

    Forty-one cases with nasopharyngeal carcinoma (NPC) treated in our department between 1991 and 2007 were clinically analyzed. The mean age of the cases was 53 years old, and the male-to female ratio was 3.6:1. The most common chief complaint was ear symptoms followed by neck, eye, and nose symptoms. The most common histology was squamous cell carcinoma, followed by undifferentiated carcinoma, adenocarcinoma, and spindle cell carcinoma. More than half of the cases were classified as clinical stage IV. For squamous cell carcinoma, undifferentiated carcinoma, spindle cell carcinoma cases, concurrent chemoradiotherapy followed by adjuvant chemotherapy was applied. For adenocarcinoma cases, transpalatal resection and postoperative radiotherapy was applied. The five-year overall survival rate was 64.1% and the disease-specific five-year survival rate was 71.2%. No significant statistical differences were seen between early stage (I, II) and late stage (III, IV), between I, II, III stage and IV stage. Recurrence occurred in 24.4% of the cases, and distant metastasis was more dominant than local recurrence. For the diagnosis and treatment of NPC, proper detection of NPC from variegated symptoms, and chemoradiotherapy for squamous cell carcinoma cases were considered to be important. (author)

    Most common malignant tumour of the kidney is Renal Cell Carcinoma (RCC) and is known for its unpredictable clinical behaviour. Aetiology and risk factors are not completely understood. Extensive workup is being done in the understanding of the disease, especially to diagnose early and to treat promptly. The objective of this study was to determine the clinical presentation and pathological pattern of RCC. Methods: After approval from ethical committee a retrospective review of records was conducted extending from January 2012 to January 2014 to identify clinical characteristics of renal cell carcinomas. The study included all renal cancer patients presented to Sheikh Zayed Hospital Lahore with in this specified period. The data was retrieved regarding, history, physical examination and necessary investigations such as ultrasonography of abdomen and pelvis and CT scan of abdomen and pelvis. Results: There were total of 50 cases. The male to female ratio was 3:2. Mean age of patients were 52.38 (18-93) years old. Most common clinical presentation was gross haematuria(66%).The mean tumour size was 8.34 (3-24) cm. Tumour histology were clear cell (84%), papillary transitional cell carcinoma (12%) and oncosytoma contributed 4%. Conclusion: We observed that large number of the patients with RCC presented with haematuria and most of them were male. Common pathological type was clear cell carcinoma. (author)

    Full Text Available Background and objective The aim of this study is to investigate the clinical characteristics of patients with primary bronchopulmonary carcinoma complicated with chronic obstructive pulmonary disease (COPD, and to optimize the early diagnoses in the coexistence of COPD and primary bronchopulmonary carcinoma. Methods The clinical data of 118 patients with COPD complicated with primary bronchopulmonary carcinoma were analyzed retrospectively, including age, sex, smoking history, smoking index, clinical symptoms and signs, pathological type, staging, metastasis site and lung function index. 120 patients with simple COPD were selected as control. Results The smoking rate (55.1% and smoking index ≥400 branch /year (90.8% of the patients with COPD complicated with primary bronchopulmonary carcinoma were higher than the simple COPD group (20.8%, 48.0%. The difference between the two groups was statistically significant (P0.05, while the incidence of hemoptysis, weight loss, chest pain, hoarseness, pleural effusion and atelectasis were significantly higher than those in simple COPD group (P0.05, but the diffusing capacity of carbon monoxide (DLCO of COPD patients complicated with primary bronchopulmonary carcinoma was lower than that of simple COPD patients (P<0.05 . In the COPD patients with primary bronchopulmonary carcinoma, squamous cell carcinoma was the most common pathological type (51.7%. Male patients were mainly squamous cell carcinoma (60.7%, while female patients with adenocarcinoma (69.0%. Conclusion COPD combined with primary bronchopulmonary carcinoma occurs in male smokers more. There is higher incidence of squamous cell carcinoma. When they are first diagnosed, most of them are advanced or located late, due to no specific clinical symptoms at the early stages. Periodic chest CT examination for COPD patients can help early diagnoses of primary bronchopulmonary carcinoma.

    The purpose of this study was to investigate the clinical findings, treatment, and outcome of patients with glassy cell carcinoma of cervix. We reviewed all cases of glassy cell carcinoma of the uterine cervix confirmed and treated at the Dongsan Medical Center, Keimyung University, between January 1993 and December 2005. There were 7 cases with histopathologically confirmed gassy cell carcinoma. A tumor was diagnosed as glassy cell carcinoma if over 50% of the tumor cell type displayed glassy cell features. Six patients with stage IB had radical hysterectomy and bilateral pelvic node dissection, and 2 of them received adjuvant external pelvic irradiation with concurrent chemotherapy. Remaining one patient with stage IIA had curative concurrent chemoradiotherapy with external pelvic irradiation and brachytherapy. There were 7 patients diagnosed as glassy cell carcinoma among the 3,745 (0.2%) patients of carcinoma of uterine cervix. The mean age of 7 patients was 44 years with range of 35 to 53 years of age. The most frequent symptom was vaginal bleeding (86%). By the punch biopsy undertaken before treatment of 7 cases, 2 only cases could diagnose as glassy cell carcinoma of uterine cervix, but remaining of them confirmed by surgical pathological examination. The mean follow up duration was 73 months with range of 13 to 150 months. All 7 patients were alive without disease after treatment. Glassy cell carcinoma of the uterine cervix is a distinct clinicopathologic entity that demonstrates an aggressive biologic behavior. However for early-stage disease, we may have more favorable clinical outcome with radical surgery followed by chemoradiotherapy

    A total of 25 cases with early gastric carcinoma, of which 10 cases were followed by gastrectomy, were given a combined radiotherapy with 5-Fu, Ft 207 or MFC at Miyagi Seijinbyo Center. Histologic examinations of biopsy specimens revealed the disappearance of cancer cells in five (42%) of 12 cases and those of serial specimens of the resected stomach showed the complete disappearance of cancer cells in three (27%) of 11 lesions (10 cases). Five year survival rate in 15 non-resected cases was only 30%. From these results, it was suggested that a combined radiotherapy of early gastric carcinoma should not be chosen as a curative treatment procedure but it might be valuable, if early carcinoma was thought to be inoperable because of other medical reasons.

    Objective: To evaluate the overall complications, major as well as minor, in patients treated for early-stage cervical carcinoma as related to treatment parameters. Methods: In this retrospective study, 167 consecutive patients with early-stage cervical carcinoma treated with preoperative radiotherapy and radical hysterectomy were investigated. Clinical data were collected from the medical files. Results: Transient or permanent complications appeared in up to half of all patients. Seven percent exhibited intraoperative complications and 35% suffered from early postoperative urinary tract problems; most frequently urinary tract infection. After one year, the urinary tract complications dominated; voidance difficulties and incontinence being most common. Gastrointestinal complications occurred in 15% of patients. Lymphedema appeared during the first year in 21% of the patients but several of the mild or moderate cases improved after the first year. The relative risk of lymphedema was increased with shorter duration of surgery, extensive preoperative irradiation to the bladder and after external postoperative irradiation. Some form of late sequelae remained in every fifth patient, and every fourth patient, aged 23-44 years, periodically suffered from vasomotor symptoms despite estrogen replacement therapy. Conclusion: The complications after radiotherapy and radical hysterectomy in early stage cervical carcinoma suggest that attempts should be made to evaluate effective treatments designed to minimize risk to the patients.

    To evaluate the early clinical experience associated with radiofrequency (RF) ablation in patients with renal cell carcinoma (RCC). The RF ablation treatment was performed on 17 tumors from 16 patients (mean age, 60.5 years; range, 43 73 years) with RCC. The treatment indications were localized, solid renal mass, comorbidities, high operation risk, and refusal to perform surgery. All tumors were treated by a percutaneous CT (n = 10), followed by an US-guided (n = 2), laparoscopy-assisted US (n = 2), and an open (n = 2) RF ablation. Furthermore, patients underwent a follow- up CT at one day, one week, one month, three and six months, and then every six months from the onset of treatment. We evaluated the technical success, technical effectiveness, ablation zone, benign periablation enhancement, irregular peripheral enhancement, and complications. All 17 exophytic tumors (mean size, 2.2 cm; range, 1.1 5.0 cm) were completely ablated. Technical success and effectiveness was achieved in all cases and the mean follow-up period was 23.8 months (range, 17 33 months). A local recurrence was not detected in any of the cases; however, five patients developed complications as a result of treatment, including hematuria (n = 2), mild thermal injury of the psoas muscle (n = 1), mild hydronephrosis (n = 1), and fistula formation (n = 1). The RF ablation is an alternative treatment for exophytic RCCs and represents a promising treatment for some patients with small RCCs.

    Full Text Available Abstract Background Ocular sebaceous carcinoma can masquerade as benign lesions resulting in delay of diagnosis. Early recognition is even more difficult in young patients where the disease rarely occurs. Here, we provide a clinicopathological correlation of ocular sebaceous carcinoma in a young individual lacking history of hereditary cancer or immunosuppression. Findings A detailed histopathological study including p53 DNA sequencing was performed on an aggressive sebaceous carcinoma presenting in a healthy 32 year-old Caucasian woman. She had no history of retinoblastoma, evidence for a hereditary cancer syndrome, or radiation therapy. However, she potentially was at risk for excessive UV light exposure. A detailed review of the literature is also provided. A moderately well differentiated sebaceous carcinoma was established histopathologically arising from the meibomian gland of the upper eyelid. In most areas, the cytoplasm contained small but distinct Oil-red-O positive vacuoles. Direct sequencing of p53 identified a G:C→A:T mutation at a dipyrimidine site. The mutation results in substitution of arginine for the highly conserved glycine at residue 199 located at the p53 dimer-dimer interface. Energy minimization structural modeling predicts that G199R will neutralize negative charges contributed by nearby inter- and intramonomeric glutamate residues. Discussion This study points to the importance of recognizing that sebaceous carcinoma can occur in young patients with no evidence for hereditary cancer risk or radiation therapy. The G199R substitution is anticipated to alter the stability of the p53 tetrameric complex. The role of UV light in the etiology of sebaceous carcinoma deserves further study. Our findings, taken together with those of others, suggest that different environmental factors could lead to the development of sebaceous carcinoma in different patients.

  16. Advice concerning the early diagnosis of bronchial carcinoma

    International Nuclear Information System (INIS)

    1982-01-01

    Bronchial carcinoma is in the Netherlands for men the most frequent type of cancer; the incidence in women is rising. In the Netherlands nowadays, per year about 7100 persons die of this disease which therefore constitutes an important public health problem. The request of advice asks - among other things - whether in the future the periodical X-ray examination of the thorax for the detection of tuberculosis of persons over 40 years can be continued for presymptomatic cases of bronchial carcinoma. The available relevant literature does not yet give indications that periodical mass radiography has any influence on the morbidity and mortality of the disease. On the other hand, literature describing clinical experience shows that the prognosis of patients with bronchial carcinoma, detected in an early presymptomatic stage, is essentially better than in the case of patients with symptomatic disease. A critical analysis of the literature does not furnish epidemiological arguments to recommend periodical mass radiography for bronchial carcinoma. However, because lungcancer forms an extremely important public health problem and because the scarcity of randomized; controlled studies in this field, the committee advises - from a scientific point of view - to perform such a study in one or preferably two regions in the Netherlands. A number of conditions are mentioned which such a study at least should meet. (Auth.)

    Thyroid cancer may be clinically evident as a tumor mass in the neck or as a histopathological incidental finding after thyroid surgery for an apparent benign condition. Our objective was to assess the differences in clinical signs, surgical management, and course between incidental and clinically diagnosed thyroid tumors. A retrospective study was conducted on patients operated on for benign or malignant thyroid disease from January 2000 to March 2014. Among the 1415 patients who underwent any thyroid surgery, 264 neoplasms were found, of which 170 were incidental. A comparison was made of incidental versus non-incidental carcinomas. Among incidental carcinomas, cases whose indication for surgery was Graves' disease were compared to those with multinodular goiter. Incidental carcinomas were in earlier stages and required less aggressive surgery. There were no differences in surgical complications between incidental and clinical tumors, but mortality and relapses were markedly higher in non-incidental cancers (4.4% vs 0% and 13.2% vs 4.8% respectively). Carcinomas developing on Graves' disease showed no differences from all other incidental tumors in terms of complications, mortality, or relapse after surgery. Early stage thyroid cancer has better survival and prognosis after surgical treatment. Copyright © 2016 SEEN. Publicado por Elsevier España, S.L.U. All rights reserved.

    From 1967 through 1985, 358 cases of early glottic carcinoma were treated with telecobalt therapy at the Department of Radiology, Osaka University Medical School. Among 278 cases treated with 2 Gy a day, the tumor response of 262 cases at 40, 50 and 60 Gy were evaluated by direct or indirect laryngoscope. The five-year local control rates of these evaluable cases of T1 and T2 glottic carcinoma were 79% and 70%, respectively. The local control rates of T1 glottic carcinoma with tumor clearance and persistence at 40 Gy were 83% (119/143) and 64% (43/67), and those of T2 cases were 86% (18/21) and 58% (18/31), respectively. The local control rates of the cases with tumor clearance and persistence at 40 Gy were same between T1 and T2 cases. The tumor clearance rates of T1 cases were significantly higher than those of T2 cases (p [de

    Five patients with early esophageal carcinoma were treated by 6-12 Gy of intracavitary irradiation following 50-60 Gy of external irradiation as a boost therapy. Surgery was not performed in these cases. None of the patients had local recurrence after radiation therapy, as demonstrated by esophagography and endoscopy. Three patients have been alive for 1-3 years 10 months. Esophageal ulceration induced by intracavitary irradiation has occurred in three of the five patients; however, intracavitary irradiation is still a beneficial treatment because of its efficacy in controlling local lesions and because radiation ulceration can eventually be cured. Intracavitary irradiation is recommended to follow external irradiation as a boost therapy for the treatment of early esophageal carcinoma

    Background and objectives The diagnosis of early oral potentially malignant disorders (OPMD) and oral squamous cell carcinoma (OSCC) is of paramount clinical importance given the mortality rate of late stage disease. The aim of this study is to review the literature to assess the current situation and progress in this area. Material and Methods A search in Cochrane and PubMed (January 2006 to December 2013) has been used with the key words “squamous cell carcinoma”, “early diagnosis” “oral cavity”, “Potentially Malignant Disorders” y “premalignant lesions”. The inclusion criteria were the use of techniques for early diagnosis of OSCC and OPMD, 7 years aged articles and publications written in English, French or Spanish. The exclusion criteria were case reports and studies in other languages. Results Out of the 89 studies obtained initially from the search 60 articles were selected to be included in the systematic review: 1 metaanalysis, 17 systematic reviews, 35 prospective studies, 5 retrospective studies, 1 consensus and 1 semi-structured interviews. Conclusions The best diagnostic technique is that which we have sufficient experience and training. Definitely tissue biopsy and histopathological examination should remain the gold standard for oral cancer diagnose. In this systematic review it has not been found sufficient scientific evidence on the majority of proposed techniques for early diagnosis of OSCC, therefore more extensive and exhaustive studies are needed. Key words: Squamous cell carcinoma, early diagnosis, oral cavity, potentially malignant disorders, premalignant lesions. PMID:25662554

    We analyzed thin-section CT, pathological, and clinical findings of peripheral lung squamous cell carcinomas, with diameters of less than 20 mm and compared these findings with solid type adenocarcinomas. CT findings of polygonal shapes, notches, pleural thickness, and cavities are more frequently found in squamous cell carcinomas than in adenocarcinomas. The pathological types can be classified in two groups: Solid types, Scirrhous types. The 5 year survival rate after resection is 64.5%, which is poorer than survival rate for solid type adenocarcinomas. It is vital to diagnose and treat peripheral squamous cell carcinomas as early as possible. (author)

    ovaries as an incidental (clinically occult) microscopic lesion in the absence of widespread pelvic carcinoma provides further evidence that STIC is the earliest form of pelvic high-grade serous carcinoma and that the fallopian tube is the site of origin. This study demonstrates the potential for complete examination of the fallopian tubes and ovaries to identify STICs and early invasive serous carcinomas that might be more amenable to the earliest intervention and potential cure.

    To compare the long-term survival outcomes of radiofrequency ablation and liver resection for single very early/early stage hepatocellular carcinoma (HCC). The Cochrane Library (Issue 3, 2015), Embase (1974 to March 15, 2015), PubMed (1950 to March 15, 2015), Web of Science (1900 to March 15, 2015), and Chinese Biomedical Literature Database (1978 to March 15, 2015) were searched to identify relevant trials. Only trials that compared radiofrequency ablation and liver resection for single very early stage (≤2 cm) or early stage (≤3 cm) HCC according to the Barcelona clinic liver cancer (BCLC) staging system were considered for inclusion in this review. The primary outcomes that we analyzed were the 3-year and 5-year overall survival (OS) rates, and the secondary outcomes that we analyzed were the 3-year and 5-year disease-free survival (DFS) rates. Review Manager 5.3 was used to perform a cumulative meta-analysis. Possible publication bias was examined using a funnel plot. A random-effects model was applied to summarize the various outcomes. Six studies involving 947 patients were identified that compared radiofrequency ablation (n=528) to liver resection (n=419) for single BCLC very early HCC. In these six studies, the rates of 3-year OS, 5-year OS, 3-year DFS, and 5-year DFS were significantly lower in the radiofrequency ablation group than in the liver resection group (risk ratio [RR] =0.90, 95% confidence interval [CI]: 0.83-0.98, P=0.01; RR =0.84, 95% CI: 0.75-0.95, P=0.004; RR =0.77, 95% CI: 0.60-0.98, P=0.04; and RR =0.70, 95% CI: 0.52-0.94, P=0.02, respectively). Ten studies involving 2,501 patients were identified that compared radiofrequency ablation (n=1,476) to liver resection (n=1,025) for single BCLC early HCC. In these ten studies, the rates of 3-year OS, 5-year OS, 3-year DFS, and 5-year DFS were also significantly lower in the radiofrequency ablation group than in the liver resection group (RR =0.93, 95% CI: 0.88-0.98, P=0.003; RR =0.84, 95% CI

    To analyze various parameters affect local control, we reviewed the results of radiotherapy for early glottic carcinoma. Between 1977 and 1997, 64 patients with untreated early glottic carcinoma and four patients with recurrent early glottic carcinoma were analyzed retrospectively. All tumors were classified as follows; T1 (n=56), T2 (n=12); well differentiated (n=33), moderately (n=25), poorly (n=1), unknown (n=9); very small tumor (VST) (n=46), small tumor (ST) (n=22). All patients were treated utilizing a cobalt-60 unit to a total dose that ranged from 56 Gy to 64 Gy (mean 60 Gy). The mean treatment time was 44 days (range 38-49). The local control rates at 2 years and 5 years for all patients were 85% and 78%, respectively. On univariate analysis, tumor size (p=0.0146) and recurrent or untreated tumor (p=0.0226) affected local control. On multivariate analysis, tumor size (p=0.0273) and recurrent or untreated tumor (p=0.0495) were also significant factors that affected local control. (author)

    Data on the differences in molecular profile between H pylori-positive and H pylori-negative early gastric carcinomas, if any, are almost nonexistent. We therefore investigated whether molecular differences can be observed between H pylori-positive and H pylori-negative early gastric carcinomas.

    We studied the usefulness of early dynamic (ED) and whole-body (WB) FDG-PET/CT for the evaluation of renal cell carcinoma (RCC). One hundred patients with 107 tumours underwent kidney ED and WB FDG-PET/CT. We visually and semiquantitatively evaluated the FDG accumulation in RCCs in the ED and WB phases, and compared the accumulation values with regard to histological type (clear cell carcinoma [CCC] vs. non-clear cell carcinoma [N-CCC]), the TNM stage (high stage [3-4] vs. low stage [1-2]), the Fuhrman grade (high grade [3-4] vs. low grade [1-2]) and presence versus absence of venous (V) and lymphatic (Ly) invasion. In the ED phase, visual evaluation revealed no significant differences in FDG accumulation in terms of each item. However, the maximum standardized uptake value and tumour-to-normal tissue ratios were significantly higher in the CCCs compared to the N-CCCs (p < 0.001). In the WB phase, in contrast, significantly higher FDG accumulation (p < 0.001) was found in RCCs with a higher TNM stage, higher Furman grade, and the presence of V and Ly invasion in both the visual and the semiquantitative evaluations. ED and WB FDG-PET/CT is a useful tool for the evaluation of RCCs. (orig.)

    Currently, using biopsy specimens to confirm suspicious liver lesions of early hepatocellular carcinoma are not entirely reliable because of insufficient sampling amount and inaccurate sampling location. It is necessary to develop a signature to aid early hepatocellular carcinoma diagnosis using biopsy specimens even when the sampling location is inaccurate. Based on the within-sample relative expression orderings of gene pairs, we identified a simple qualitative signature to distinguish both hepatocellular carcinoma and adjacent non-tumour tissues from cirrhosis tissues of non-hepatocellular carcinoma patients. A signature consisting of 19 gene pairs was identified in the training data sets and validated in 2 large collections of samples from biopsy and surgical resection specimens. For biopsy specimens, 95.7% of 141 hepatocellular carcinoma tissues and all (100%) of 108 cirrhosis tissues of non-hepatocellular carcinoma patients were correctly classified. Especially, all (100%) of 60 hepatocellular carcinoma adjacent normal tissues and 77.5% of 80 hepatocellular carcinoma adjacent cirrhosis tissues were classified to hepatocellular carcinoma. For surgical resection specimens, 99.7% of 733 hepatocellular carcinoma specimens were correctly classified to hepatocellular carcinoma, while 96.1% of 254 hepatocellular carcinoma adjacent cirrhosis tissues and 95.9% of 538 hepatocellular carcinoma adjacent normal tissues were classified to hepatocellular carcinoma. In contrast, 17.0% of 47 cirrhosis from non-hepatocellular carcinoma patients waiting for liver transplantation were classified to hepatocellular carcinoma, indicating that some patients with long-lasting cirrhosis could have already gained hepatocellular carcinoma characteristics. The signature can distinguish both hepatocellular carcinoma tissues and tumour-adjacent tissues from cirrhosis tissues of non-hepatocellular carcinoma patients even using inaccurately sampled biopsy specimens, which can aid early

    The pathological and clinical features of invasive lobular carcinoma (ILC) differ from those of invasive ductal carcinoma (IDC). Several studies have indicated that patients with ILC have a better prognosis than those with ductal carcinoma. However, no previous study has considered the molecular subtypes and histological subtypes of ILC. We compared prognosis between IDC and classical, luminal type ILC and developed prognostic factors for early breast cancer patients with classical luminal ILC. Four thousand one hundred ten breast cancer patients were treated at the Aichi Cancer Center Hospital from 2003 to 2012. We identified 1,661 cases with luminal IDC and 105 cases with luminal classical ILC. We examined baseline characteristics, clinical outcomes, and prognostic factors of luminal ILC. The prognosis of luminal ILC was significantly worse than that of luminal IDC. The rates of 5-year disease free survival (DFS) were 91.9% and 88.4% for patients with luminal IDC and luminal ILC, respectively (P = 0.008). The rates of 5-year overall survival (OS) were 97.6% and 93.1% for patients with luminal IDC and luminal ILC respectively (P = 0.030). Although we analyzed prognosis according to stratification by tumor size, luminal ILC tended to have worse DFS than luminal IDC in the large tumor group. In addition, although our analysis was performed according to matching lymph node status, luminal ILC had a significantly worse DFS and OS than luminal IDC in node-positive patients. Survival curves showed that the prognosis for ILC became worse than IDC over time. Multivariate analysis showed that ILC was an important factor related to higher risk of recurrence of luminal type breast cancer, even when tumor size, lymph node status and histological grade were considered. Luminal ILC had worse outcomes than luminal IDC. Consequently, different treatment approaches should be used for luminal ILC than for luminal IDC.

  12. Does multifocal papillary micro-carcinoma require radioiodine ablation?

    Full text of publication follows. Background: the thyroid carcinomas smaller than 1 cm (micro-carcinomas) comprise a significant fraction of papillary carcinomas. Excluding clinical micro-carcinomas, which present as metastatic disease, the micro-carcinomas diagnosed by ultrasound/FNAC or incidentally have very good prognosis. However, whether or not these papillary micro-carcinomas require post-surgical radioiodine ablation remains a matter of debate. Hypothesis: multi-focality is present in majority of clinical papillary micro-carcinomas and this characteristic can be used to identify the subset of non-clinical micro-carcinomas with greater malignant potential. Methods: the data on types of differentiated thyroid carcinomas diagnosed in the period 2008-2011 in the University Hospital Split were collected. Results: there were 359 patients with thyroid carcinoma, 329 (92%) of which had papillary carcinoma. About 61% (202/329) of papillary carcinomas were micro-carcinomas; most of them were diagnosed by ultrasound/FNAC (134/202= 66%), the rest were incidentalomas (48/202=24%) and clinical micro carcinomas (20/202=10%). Sixty percent (12/20) of patients with clinical micro-carcinoma and 23 patients with non-clinical micro-carcinoma (23/182=13%) had multifocal disease. Conclusion: multifocal disease is a frequent characteristic of clinical papillary thyroid micro-carcinomas, suggesting that multi-focality presents an early stage of non-clinical micro-carcinomas with more aggressive behaviour. Thus multifocal, but not uni-focal papillary micro-carcinomas may require radioiodine ablation. (authors)

    Full Text Available Gastric carcinoma is one of the major causes of cancer-related mortality worldwide. Early detection and treatment leads to an excellent prognosis in patients with early gastric cancer (EGC, whereas the prognosis of patients with advanced gastric cancer (AGC remains poor. It is unclear whether EGCs and AGCs are distinct entities or whether EGCs are the beginning stages of AGCs. We performed whole exome sequencing of four samples from patients with EGC and compared the results with those from AGCs. In both EGCs and AGCs, a total of 268 genes were commonly mutated and independent mutations were additionally found in EGCs (516 genes and AGCs (3104 genes. A higher frequency of C>G transitions was observed in intestinal-type compared to diffuse-type carcinomas (P = 0.010. The DYRK3, GPR116, MCM10, PCDH17, PCDHB1, RDH5 and UNC5C genes are recurrently mutated in EGCs and may be involved in early carcinogenesis.

    Histologic subclassification of high-grade endometrial carcinomas can sometimes be a diagnostic challenge when based on histomorphology alone. Here we utilized immunohistochemical markers to determine the immunophenotype in histologically ambiguous high-grade endometrial carcinomas that were initially diagnosed as pure or mixed high-grade endometrioid carcinoma, aiming to determine the utility of selected immunohistochemical panel in accurate classification of these distinct tumor types, while correlating these findings with the clinical outcome. A total of 43 high-grade endometrial carcinoma cases initially classified as pure high-grade endometrioid carcinoma (n=32), mixed high-grade endometrioid carcinoma/serous carcinoma (n=9) and mixed high-grade endometrioid carcinoma/clear cell carcinoma (n=2) were retrospectively stained with a panel of immunostains, including antibodies for p53, p16, estrogen receptor, and mammaglobin. Clinical follow-up data were obtained, and stage-to-stage disease outcomes were compared for different tumor types. Based on aberrant staining for p53 and p16, 17/43 (40%) of the high-grade endometrial carcinoma cases initially diagnosed as high-grade endometrioid carcinoma were re-classified as serous carcinoma. All 17 cases showed negative staining for mammaglobin, while estrogen receptor was positive in only 6 (35%) cases. The remaining 26 cases of high-grade endometrioid carcinoma showed wild-type staining for p53 in 25 (96%) cases, patchy staining for p16 in 20 (77%) cases, and were positive for mammaglobin and estrogen receptor in 8 (31%) and 19 (73%) cases, respectively, thus the initial diagnosis of high-grade endometrioid carcinoma was confirmed in these cases. In addition, the patients with re-classified serous carcinoma had advanced clinical stages at diagnosis and poorer overall survival on clinical follow-up compared to that of the remaining 26 high-grade endometrioid carcinoma cases. These results indicate that selected

    Full Text Available Context: It has been shown that ovarian carcinoma subtypes are distinct pathologic entities with differing prognostic and therapeutic implications. Histotyping by pathologists has good reproducibility, but occasional cases are challenging and require immunohistochemistry and subspecialty consultation. Motivated by the need for more accurate and reproducible diagnoses and to facilitate pathologists′ workflow, we propose an automatic framework for ovarian carcinoma classification. Materials and Methods: Our method is inspired by pathologists′ workflow. We analyse imaged tissues at two magnification levels and extract clinically-inspired color, texture, and segmentation-based shape descriptors using image-processing methods. We propose a carefully designed machine learning technique composed of four modules: A dissimilarity matrix, dimensionality reduction, feature selection and a support vector machine classifier to separate the five ovarian carcinoma subtypes using the extracted features. Results: This paper presents the details of our implementation and its validation on a clinically derived dataset of eighty high-resolution histopathology images. The proposed system achieved a multiclass classification accuracy of 95.0% when classifying unseen tissues. Assessment of the classifier′s confusion (confusion matrix between the five different ovarian carcinoma subtypes agrees with clinician′s confusion and reflects the difficulty in diagnosing endometrioid and serous carcinomas. Conclusions: Our results from this first study highlight the difficulty of ovarian carcinoma diagnosis which originate from the intrinsic class-imbalance observed among subtypes and suggest that the automatic analysis of ovarian carcinoma subtypes could be valuable to clinician′s diagnostic procedure by providing a second opinion.

    Full Text Available Background/Aims Radiofrequency ablation (RFA is one of the most frequently applied curative treatments in patients with a single small hepatocellular carcinoma (HCC. However, the clinical significance of and risk factors for early massive recurrence after RFA—a dreadful event limiting further curative treatment—have not been fully evaluated. Methods In total, 438 patients with a single HCC of size ≤3 cm who underwent percutaneous RFA as an initial treatment between 2006 and 2009 were included. Baseline patient characteristics, overall survival, predictive factors, and recurrence after RFA were evaluated. In addition, the incidence, impact on survival, and predictive factors of early massive recurrence, and initial recurrence beyond the Milan criteria within 2 years were also investigated. Results During the median follow-up of 68.4 months, recurrent HCC was confirmed in 302 (68.9% patients, with early massive recurrence in 27 patients (6.2%. The 1-, 3-, and 5-year overall survival rates were 95.4%, 84.7%, and 81.8%, respectively, in patients with no recurrence, 99.6%, 86.4%, and 70.1% in patients with recurrence within the Milan criteria or late recurrence, and 92.6%, 46.5%, and 0.05% in patients with early massive recurrence. Multivariable analysis identified older age, Child-Pugh score B or C, and early massive recurrence as predictive of poor overall survival. A tumor size of ≥2 cm and tumor location adjacent to the colon were independent risk factors predictive of early massive recurrence. Conclusions Early massive recurrence is independently predictive of poor overall survival after RFA in patients with a single small HCC. Tumors sized ≥2 cm and located adjacent to the colon appear to be independent risk factors for early massive recurrence.

    We created a new clinical staging system for end-stage gastrointestinal (GI) carcinoma to clarify the therapeutic goals for these patients. Data were obtained from a retrospective review of medical charts. Based on daily clinical observation of 144 patients with end-stage GI carcinoma, we classified the terminal stages as A, B, C, and D. The mean durations of terminal stages A, B, C, and D were 19, 16.6, 6.6, and 1.8 days, respectively, in patients with end-stage gastric cancer and 28.5, 9.1, 5.4, and 1.9 days, respectively, in patients with colorectal cancer. Moreover, 88.0% of patients with gastric carcinoma and 82.6% of patients with colorectal carcinoma passed through terminal stages A, B, C, and D sequentially. The patients in terminal stage B experienced temporary relief of symptoms, but those in terminal stage C did not (P terminal stages can easily be judged by clinical observation and may be an effective new tool with which to manage patients with end-stage GI carcinoma and their families.

    Aim: To assess clinical outcome of transarterial chemoembolization (TACE) in a series of patients with early-stage hepatocellular carcinoma (HCC), within Milan criteria, but clinically unfit for liver transplantation (OLT). Methods: From January 2006 to May 2009, 67 patients (43 males, mean age 70 ± 7.6 years) with very early or early-stage unresectable HCC, within Milan selection criteria but clinically unfit for OLT, underwent TACE. The primary endpoint of the study was overall survival. Secondary endpoints were: safety, liver toxicity, 1-month tumour response according to the amended RECIST criteria, time to local and distant intrahepatic tumour recurrence and time to radiological progression. Results: Two major periprocedural complications occurred (3%), consisting of liver failure. Periprocedural mortality rate was 1.5% (1 patient). A significant increase in ALT and bilirubin levels 24 h after treatment was reported, with progressive decrease at discharge. At 1-month follow-up, complete and partial tumour response rates were 67.2% and 29.8%, respectively, with two cases of progressive disease. Mean follow-up was 37.3 ± 15 months. The 1-, 2-, and 3-year overall survival rates were 90.9%, 86.1%, and 80.5%, respectively. Median expected time to local tumour recurrence and intrahepatic tumour recurrence were 7.9 and 13.8 months, respectively. Radiological disease progression was observed in 12 patients (17.9%) with a mean expected time of 26.5 months. Conclusion: In patients with early-stage HCC, clinically excluded from OLT and unfit for surgery or percutaneous ablation, TACE is a safe and effective option, with favourable long-term survival.

    From 250 patients of the Clinic and Policlinic for Radiology at the University of Munich from 1975 to 1979 the radiomorphology of the central and peripheral bronchial carcinoma is demonstrated. The sex ratio of 6.3/1, the age distribution with its peak between 60 and 70 years of age and the localisations with a predominance in the right lung and a preferred infection of the upper lobes from our study agreed with the results from the literature. Characteristic early symptoms are missing with bronchial carcinoma, although clinical symptoms in the rule are the first evidence. For early recognition the first and easiest diagnostic procedure is the radiological examination of the thorax in two planes. Circular foci and peripheral tumor shadows, which occur with the spreading of the mediastinum or the hilus, in these patients about 50%, are in large amounts suspicious of a malignancy and indicate an advanced stage. Because the prognosis of the bronchial carcinoma depends on the histological structure of the tumor and on the point in time of diagnosis, an improvement of the life expectancy can only be reached by early detection. In the risk group of smokers over 40 years of age and of professionally exposed people, even minor changes should be considered as carcinoma until the opposite can be proven. (orig./TRV) [de

    Prostate cancer is the most common male cancer. Insufficient knowledge of PCa among men causes its low detection. Lack of essential actions in health education and widely understood prophylaxis, the need of the latter are maybe responsible for the increasing mortality rate. According to our assumption, educating men increase their awareness on the need of screening tests and results in increasing reporting to physical examinations. This in turn allows for an early detection of the disease. A research was conducted between the years 2003-2009 on the knowledge of PCa among 260 men. They were divided into two groups. Group A - 63 patients treated for carcinoma of prostate and group B - 197 men reporting spontaneously to screening tests. In order to check the adopted hypothesis, we prepared an educational material and test of knowledge - test with a questionnaire. Knowledge was evaluated before (test I) and after the education process (test II). Until 2009, we were monitoring the number of patients from group B reporting to screening tests and their knowledge was once again checked (test III). Two subgroups C and D were created from group B - 117 healthy men and 80 with diagnosed diseases respectively (70 with benign prostatic hyperplasia, 7 with prostatitis, and 3 with carcinoma of prostate). Patients with prostatitis and PCa and 3 patients from group C not reporting to the tests were excluded from further monitoring. Maths statistics with the use of SPSS 12.0 PL program and Statistica 6.0 constituted the base for working out the results. We observed a higher knowledge about carcinoma of prostate in group A than in group B (p 40 from groups C and D were interested in health care (p70 a lower level of motivation was observed. The interest was proportional to the level of education, and this was differentiating in an analogical way the motivation to extend knowledge about prostate cancer (padvanced state, and during 5 years in group C - in 4 men at an early development

    Full text: Analysis of data of the oncological outpatient clinics of the Republic of Uzbekistan confirms our data obtained in the Institute of Endocrinology showing growth in iodine deficiency disorders. In the Republic of Uzbekistan, during period from 1983 to 1999, 6374 people were detected to have thyroid carcinoma. If in 1989, 1.95 cases of thyroid tumor accounted for 100000 population, in 1999 this index reached to 2.39. Moreover, among metropolitan population this was 4.6 cases in 1989, and 8.0 in 1999. Of the 4280 patients operated for different thyroid pathologies from 1989 to 1999 in the Institute of Endocrinology, 335 (7.9%) were diagnosed to have thyroid carcinoma. Clinical presentation was: multinodular goiter in 50.8%, nodular goiter in 37.3% and autoimmune thyroiditis in 4.2% of cases. The average age of patients operated for thyroid carcinoma was 42.8 years in 1989 and 32 years in 1999. Treatment of patients with thyroid carcinoma should be near total thyroidectomy with selective lymphadenectomy independent of morphologic form of the tumor. Our data showed that only surgical method of treatment was used in 7.4% of patients but in combination of radioiodine in 81.9% of patients. Radioiodine was used to destroy remnant thyroid tissue and iodine concentrating metastases. 131I treatment for destruction of thyroid remnants after measured from the front, back and lateral positions in radical operation was given by fractionation method with average total activity being 25 mCi to 75 mCi. Metastases into neck lymph nodes and mediastinum were treated with radioactivity ranging from 50 mCi to 100 mCi. Of the total patients of differentiated thyroid cancer treated from 1995-1999, 148 were alive on 01.01.2003 with five-year survival rate of 91.4%. Our results highlight that combined surgical and radioiodine treatment of thyroid carcinoma helps in preventing recurrence, metastasis and results in increasing the lifespan of patients. (author)

    Sarcomatoid carcinoma is a rare variant of squamous cell carcinoma of the head and neck. No consensus exists on its management. Our aim was to present our outcomes. Retrospective study. Median follow-up 45 months. There were 38 patients with pathologically confirmed sarcomatoid carcinoma of the larynx treated at the Mayo Clinic from 1990 to 2014. Statistical analysis of overall survival (OS), progression-free survival (PFS), and local control (LC) were conducted using the Kaplan-Meier method. The majority of patients were elderly males (92%) with a smoking history (74%) presenting with early-stage disease (71%). Surgery alone was the primary treatment in 27 patients (71%). Nine patients (25%) were treated with adjuvant radiation due to initial stage or high-risk pathologic features. Median radiation dose to the primary/surgical bed was 65 Gy (range, 60.3-75.0 Gy). A total of 15 patients (39%) had tumor recurrence, majority being local (n = 12). Sixty percent (n = 9) had multiple local recurrences. Five-year OS, PFS, and LC were 63%, 46%, and 72%, respectively. Subgroup analysis by stage I versus higher stages (II-IV) showed an OS of 80% versus 43% (P = .030), PFS of 65% versus 18% (P = .003), and LC of 84% versus 57% (P = .039). Sarcomatoid carcinoma of the larynx is rare, and frequently presents at an early stage in older men with history of smoking. Based on our outcomes and patterns of failure, it appears early-stage tumors are treated appropriately with single-modality therapy, whereas more advanced tumors require multimodality therapy. Validation in a larger cohort is warranted. 4. Laryngoscope, 128:373-377, 2018. © 2017 The American Laryngological, Rhinological and Otological Society, Inc.

HCC is usually asymptomatic at potential curative stages, and it has very poor prognosis if detected later. Thus, the identification of early biomarkers and novel therapies is essential to improve HCC patient survival. Ion channels have been proposed as potential tumor markers and therapeutic targets for several cancers including HCC. Especially, the ether à-go-go-1 (Eag1 voltage-gated potassium channel has been suggested as an early marker for HCC. Eag1 is overexpressed during HCC development from the cirrhotic and the preneoplastic lesions preceding HCC in a rat model. The channel is also overexpressed in human HCC. Astemizole has gained great interest as a potential anticancer drug because it targets several proteins involved in cancer including Eag1. Actually, in vivo studies have shown that astemizole may have clinical utility for HCC prevention and treatment. Here, we will review first some general aspects of HCC including the current biomarkers and therapies, and then we will focus on Eag1 channels as promising tools in the early diagnosis of HCC.

    The behaviour of each basal cell carcinoma is known to be different according to the histological growth pattern. Among these aggressive lesions, sclerodermiform basal cell carcinomas are the most common type. This is a challenging-to-treat lesion due to its deep tissue invasion, rapid growth, risk of metastasis and overall poor prognosis if not diagnosed in early stages. To investigate if sclerodermiform basal cell carcinomas are diagnosed later compared to non-sclerodermiform basal cell carcinoma Method: All lesions excised from 2000 to 2010 were included. A pathologist classified the lesions in two cohorts: one with specimens of non-aggressive basal cell carcinoma (superficial, nodular and pigmented), and other with sclerodermiform basal cell carcinoma. For each lesion, we collected patient's information from digital medical records regarding: gender, age when first attending the clinic and the tumor location. 1256 lesions were included, out of which 296 (23.6%) corresponded to sclerodermiform basal cell carcinoma, whereas 960 (76.4%) were non-aggressive subtypes of basal cell carcinoma. The age of diagnosis was: 72.78±12.31 years for sclerodermiform basal cell and 69.26±13.87 years for non-aggressive basal cell carcinoma (Pbasal cell carcinomas are diagnosed on average 3.52 years later than non-aggressive basal cell carcinomas. Sclerodermiform basal cell carcinomas were diagnosed 3.40 years and 2.34 years later than non-aggressive basal cell carcinomas in younger and older patients respectively (P=.002 and P=.03, respectively). retrospective design. The diagnostic accuracy and primary clinic conjecture of sclerodermiform basal cell carcinomas is quite low compared to other forms of basal cell carcinoma such as nodular, superficial and pigmented. The dermoscopic vascular patterns, which is the basis for the diagnosis of non-melanocytic nonpigmented skin tumors, may not be particularly useful in identifying sclerodermiform basal cell carcinomas in early stages

    Recently the usefulness of thallium 201 chloride (201Tl) as a tumor imaging agent for various tumors has been reported. However, the application of 201Tl SPECT to oral squamous cell carcinomas has not been established. The purpose of this study is to investigate the usefulness of 201Tl SPECT in the assessment of malignancy or in the differential diagnosis of oral squamous cell carcinomas from inflammatory diseases. Thirty-two patients with 33 primary oral squamous cell carcinomas and 4 patients with inflammatory disease were studied. SPECT images were acquired 15 minutes (early image) and 3 hours (delayed image) after the intravenous injection with 74 MBq 201Tl, and then early uptake ratio (ER), delayed uptake ratio (DR), and retention index (RI) were measured. The relations between these parameters and the size, the site, the degree of differentiation and the mode of invasion of the primary tumor were analyzed statistically. 201Tl SPECT correctly identified 32 of the 33 tumors, with 32 patients having oral squamous cell carcinoma, making the positive rate 97%. Significant negative correlation was observed between RI and major or minor axis of tumors; therefore, this study revealed that RI was influenced by the size of a tumor. In comparison with the average value of RI according to histopathological diagnosis, there was statistically significant difference (p=0.011) between carcinomas (0.80±0.16, n=30) and inflammatory diseases (0.58±0.04, n=4); thus, it was supposed that differential diagnosis between them could be possible. About the tumors with the range of minor-axis 20 mm-40 mm for little influence of tumor size to the RI, the tendency to decrease for the RI of well-differentiated group or low-invasive group was seen. For oral squamous cell carcinomas, 201Tl SPECT had a high positive rate. The application was suggested for use in the differential diagnosis between inflammatory disease and carcinomas, where clinical usefulness could be expected. (author)

    Objective: To study dual-phase helical CT for the evaluation of early pancreatic cacinoma. Methods: Dual-phase helical CT was performed on 21 patients with early pancreatic carcinoma. In the enhanced imaging the contrast material was intravenously injected in a dose of 1.5 ml/kg at a rate of 3 ml/s. The image acquisition of the lesion in pancreatic phase (PP) and portal venous phase (PVP) were started at 35 seconds and 65 seconds after the start of the injection respectively. The enhancement of normal pancreas and tumor during the two phases was observed and compared. All data were statistically analyzed. Results: Tumor-pancreas contrast was significantly greater in PP (45.16±113.23) HU than in PVP (23.15±12.44) HU (t=2.13, P<0.01). Conclusion: Dual-phase helical CT scan for pancreas, including the imaging of the pancreatic and portal , venous phase, can be applied as an optimal selection. It can delineate early pancreatic carcinoma clearly and provide more information for the diagnosis of the lesion. The tumor-pancreas contrast was much higher' in PP than in PVP. (authors)

    The esophageal squamous cell carcinoma (ESCC) is usually develped from low-grade intraepithelial neoplasia (LGIEN) and high-grade intraepithelial neoplasia (HGIEN) to infiltrative squamous cell carcinoma. Till now, it remains hard to screen for infiltration at earlier stages, especially the differentiation between HGEIN and early infiltrative carcinoma. The purpose of this study is to determine a role of podoplanin in differentiating between HGEIN and early infiltrative squamous cell carcinoma. Totally 133 patients pathologically diagnosed with early ESCC and/or precancerous lesions were enrolled.The EnVision two-step IHC staining technique was applied using the monoclonal mouse anti-human Podoplanin antibody (clone number: D2-40). The expressions of PDPN protein on the basal layer of squamous epithelium lesions could be divided into three different patterns: complete type, incomplete (non-continuous) type, or missing type. A diagnosis of HGEIN can be made if the basal layer showed non-continuous or complete expression of PDPN and a diagnosis of early infiltration can be made if the expression of PDPN is completely missing. Our study confirmed that PDPN was a potential biomarker to identify the presence of early infiltrative squamous cell carcinoma.

    Mucoepidermoid carcinoma is the most common malignant tumor of salivary glands. However, it is a rare entity in larynx. Laryngeal cases are frequently misdiagnosed with other malignancies and they are under-reported. So, recognizing the clinical and histological features of this tumor is essential. Laryngeal mucoepidermoid carcinoma can arise in supraglottis, glottis and subglottis. Generally, it presents as a submucosal mass; therefore, progressive symptoms without any identifiable lesion in...

    To describe the clinical and imaging findings of hepatocellular carcinoma with neuroendocrine differentiation, which is an extremely rare variant of hepatocellular carcinoma. We collected five patients who had histopathologically proven hepatocellular carcinoma with neuroendocrine differentiation, and described morphologic feature, enhancement pattern of tumors, extrahepatic manifestation and clinical findings. At CT, the tumor size ranged from 8 to 17 cm (mean: 12 cm) in maximum diameter. The tumor margin was well-defined and smooth in four patients and all tumors were heterogeneously hypoattenuating. Four tumor showed rim enhancement on arterial and portal phases. Local invasion to the portal vein, intrahepatic duct and gallbladder were seen. Extrahepatic manifestations included hepatic metastases, lymph node metastasis. At ultrasonography, the tumor showed heterogeneously hyperechoic in all patients and hypoechoic rim was found in four patients. Of four patients who were followed up, one survived for 16 months after initial diagnosis, while the other three died within 3 months after initial diagnosis. As described above, clinical and imaging findings of hepatocellular carcinoma with neuroendocrine differentiation were not specific. However, this rare variant of hepatocellular carcinoma could be considered when hepatic tumor is found in an advanced stage and shows persistent rim enhancement at CT

    Full Text Available The objective of this study was to present some clinical and radiological manifestations of PNS in relation to bronchogenic carcinoma (BC and to evaluate the usefulness of imaging findings in the diagnosis of asymptomatic BC. In the study group of 204 patients (146 male and 58 female with proven bronchogenic carcinoma, PNS was present in 18 (8.62% patients. The patients with PNS were divided into two groups. The first one consisted of 13 (72.2% patients with symptoms related to primary tumours while the second one consisted of 5 (27.7% patients with symptoms, at initial appearance, indicative of disorders of other organs and systems. The predominant disorder was Lambert-Eaton Syndrome, associated with small-cell carcinoma. Endocrine manifestations included: inappropriate antidiuretic hormone production syndrome (small-cell carcinoma, a gonadotropin effect with gynaecomastia and testicular atrophy (planocellular carcinoma, small-cell carcinoma, a case of Cushing Syndrome (small-cell carcinoma, and hyper-calcaemia, due to the production of the parathyroid hormone-related peptide, which was associated with planocellular carcinoma. A rare case of bilateral exophthalmos was found as PNS at adenocarcinoma. Digital clubbing and hypertrophic osteoarthropathy (HO were associated with planocellular and adenocarcinoma, while clubbing was much more common than HO, especially among women. The differences between the two groups were related to the time of PNS appearance. In the first group, PNS occurred late on in the illness, while in the second group, PNS preceded the diagnosis of BC. Alternatively, the disappearance of a clinical or a radiological manifestation of PNS after surgery or chemotherapy may be an indicator of an improvement in health or PNS may be the first sign of illness recurrence. Radiological manifestations of PNS in asymptomatic patients may serve as a useful screen for identifying primary BC. In symptomatic patients, it may be an

    2013-01-01

    Multilocular cystic renal cell carcinoma (MCRCC) is a subtype of clear cell renal cell carcinoma and has mild clinical symptoms and a favorable prognosis. Accordingly, nephron-sparing surgery is recommended as a therapeutic strategy. If histologic subtype of MCRCC can be predicted preoperatively with an acceptable level of accuracy, it may be important in predicting prognosis and make clinical management. Most MCRCCs show characteristic cross-sectional imaging findings and permit accurate diagnosis before the treatment. Cross -sectional imaging of MCRCC reveals a well -defined multilocular cystic mass with irregularly enhanced thickened septa and without enhanced intracystic solid nodule. It is often classified as Bosniak classification Ⅲ , which is significantly different from that of other renal cystic masses. The clinical, pathologic, and radiologic features of MCRCC were discussed and illustrated in this article. The role of the imaging preoperative evaluation for MCRCC, and management implications were emphasized. (authors)

    One hundred and thirty-five sites of oral carcinoma (118 patients) treated in our department during 15 years (1991 to 2005) were clinically analyzed. Multiple carcinomas within the oral cavity arose in 17 sites. In our department, tongue and oral floor were common subsites, followed by buccal mucosa, gingiva, lip, and hard palate. The number of patients increased according to the elevation of clinical stage. Since the subsites and stage characteristics of our department might be due to patients' distribution among medical and dental clinics, correlation of information among medical and dental schools was considered important The significance of multiple malignancies in patients with oral carcinoma was confirmed since multiple malignancies within and outside of the oral cavity occurred at a high rate. The five-year survival rate was 73.8% in tongue carcinoma patients and 58.9% in oral floor carcinoma patients, and the prognosis of patients was fair with positive application of surgery. Since the prognosis of patients without surgery was poor, it is important to consider the treatment strategy for patients who reject surgery and to recommend that they visit a clinic before the tumor advances to an unresectable stage.

Therefore, the imaging criteria for hepatocellular carcinoma (HCC are also usually based on vascular findings, eg, early arterial uptake followed by washout in the portal venous and equilibrium phases. Contrast-enhanced ultrasonography, dynamic multidetector-row computed tomography (MDCT, and dynamic magnetic resonance (MR imaging with gadopentetate dimeglumine (Gd-DTPA are useful for detecting hypervascular HCC on the basis of vascular criteria but are not as useful for hypovascular HCC. Contrast-enhanced MR imaging with gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid (Gd-EOB-DTPA, a hepatocyte-specific MR contrast agent, is superior to dynamic MDCT and dynamic MR imaging with Gd-DTPA in detecting both hypervascular and hypovascular HCC. Moreover, Gd-EOB-DTPA-enhanced MR imaging can display each histologically differentiated HCC as hypointense relative to the liver parenchyma. 18F-fluorodeoxyglucose positron emission tomography imaging might not be suitable for the screening and detection of HCC, given its lower diagnostic performance. However, this technique plays an important role in determining whether HCC has spread beyond the liver. Keywords: hepatocellular carcinoma, evaluation, imaging, clinical utility

    Objective: To investigate the expression and clinical significance of KIAA1199 in primary hepatocellular carcinoma. Methods: A total of 136 cases of primary hepatocellular carcinoma tissues and paired adjacent tissues were collected. Immunohistochemistry and Western blot were used to detect the expression of KIAA1199 in primary hepatocellular carcinoma tissues and paired adjacent tissues. The relationship between KIAA1199 and clinicopathological parameter of primary hepatocellular carcinoma was analyzed. Results: The positive rate of KIAA1199 in primary hepatocellular carcinoma was 82.3% (112/136), which was higher than that in paired para-cancerous tissues (14.7%, 20/136). High expression of KIAA1199 was significantly correlated with age, cirrhosis history, tumor size, tumor number, degree of differentiation, TNM staging and microvenous invasion (MVI) ( P 0.05). The Kaplan-Meier survival curves indicated that high KIAA1199 expression was associated with poor survival ( P hepatocellular carcinoma, which is significantly correlated with the clinicopathological features and prognosis, high expression of KIAA1199 increased the risk of death in patients with primary hepatocellular carcinoma.

    Purpose We retrospectively analyzed anatomo-clinic, therapeutic and progressive particularities of 74 young patients (= 20 years) with nasopharyngeal carcinoma treated between 1993 and 2005. Patients and methods Initial work-up included a fiberoptic naso-fiberscopy with biopsy, computed tomography and/or MRI of nasopharynx and neck, chest X-ray, abdominal ultrasonography and bone scan. Patients were treated with either primary chemotherapy (epirubicin and cisplatin) followed by radiotherapy or concomitant radio chemotherapy (five fluorouracil and cisplatin). Radiotherapy was delivered to a total dose of 70 to 75 Gy to nasopharynx and involved cervical lymph nodes and 50 Gy to the remainder cervical areas. Results The median age was 16 years. Sixty-three percent of patients had undifferentiated tumors. Sixty-six percent had locally advanced tumor. With a median follow-up of 107 months, one patient presented a local relapse, 24 patients developed distant metastases with a median delay of 7 months. The 5 years overall survival and disease-free survival were 66 and 65 %. Late complications were dominated by dry mouth and endocrine disorders. Comments Pediatric nasopharyngeal carcinoma is characterized by an early metastatic diffusion. Local control is excellent but with severe late toxicities. New techniques of radiotherapy and new molecules of chemotherapy could improve these results. (authors)

    Purpose/Objective: The course will be divided into three major topics: (1) Review of radiobiological principles as they apply to the radiotherapeutic management of skin carcinomas; (2) review of radiotherapeutic techniques including beam qualities, beam collimation, tissue dose profiles, and the relative indications of external beam irradiation vs. brachytherapy; (3) comprehensive review of the tumor biology of skin malignancies, including malignant melanoma, and of the relative indications for radiotherapeutic and/or surgical management. (1) Review of critical data which have led to currently applied principles of time-dose-volume concepts in the radiotherapeutic management of skin carcinomas. Emphasis will be placed on the relative importance of fraction size and overall treatment time on tumor control probability and acute and late normal tissue toxicity. (2) Considering that radiotherapy in the management of skin carcinomas is often used to minimize patient disfiguration and to preserve critical body functions (e.g. eye lids) the technical aspects of radiotherapy delivery are most critical. Careful evaluation of the extent of the lesions including evaluation of their depth of invasion will determine the quality of the radiation beams, orthovoltage and low energy electrons being the most useful. Beam harding for orthovoltage beams and secondary and tertiary (skin) collimation of appropriate electron beams are critical. For more extensive and deeply invasive lesions contour-shaping through customized bolus material is essential. Equally important is the familiarity with custom shielding of critical structures, such as eyes, ears, oral cavity and central nervous system structures. Brachytherapy applications in the treatment of skin carcinomas is limited but should be considered when implants with high dose uniformity can be constructed. (3) The discussion of clinical management will start with a discussion of properties and routes of spread of the diverse

    Purpose: To review the factors that influence outcome and patterns of relapse in patients with cutaneous squamous cell carcinoma (SCC) and basal cell carcinoma (BCC) with perineural infiltration (PNI) without clinical or radiologic features, treated with surgery and radiotherapy. Methods and Materials: Between 1991 and 2004, 222 patients with SCC or BCC with PNI on pathologic examination but without clinical or radiologic PNI features were identified. Charts were reviewed retrospectively and relevant data collected. All patients were treated with curative intent; all had radiotherapy, and most had surgery. The primary endpoint was 5-year relapse-free survival from the time of diagnosis. Results: Patients with SCC did significantly worse than those with BCC (5-year relapse-free survival, 78% vs. 91%; p < 0.01). Squamous cell carcinoma with PNI at recurrence did significantly worse than de novo in terms of 5-year local failure (40% vs. 19%; p < 0.01) and regional relapse (29% vs. 5%; p < 0.01). Depth of invasion was also a significant factor. Of the PNI-specific factors for SCC, focal PNI did significantly better than more-extensive PNI, but involved nerve diameter or presence of PNI at the periphery of the tumor were not significant factors. Conclusions: Radiotherapy in conjunction with surgery offers an acceptable outcome for cutaneous SCC and BCC with PNI. This study suggests that focal PNI is not an adverse feature.

    Ovarian carcinomas consist of a heterogeneous group of malignant epithelial neoplasms with specific pathogenic mechanisms. This review provides a brief introduction to the different pathways of tumor progression and the associated molecular changes. However, the main focus will be on two areas with major paradigm shifting developments in recent years. Mutational analysis of ovarian clear cell carcinomas, endometrioid carcinomas and endometriotic lesions identified mutations in the ARID1A gene as common and early genetic changes in carcinomas with associated endometriosis and in atypical endometriosis itself. Extensive pathological work-up of the fallopian tubes of BRCA1/2 mutation carriers have demonstrated the existence of serous tubal intraepithelial carcinomas (STIC). Further studies showed that this lesion can also be found in 50-60% of patients with serous ovarian carcinomas without BRCA1/2 germline mutations. Pre-precursors which share the p53 mutations with STICs but proliferate very little are called p53-signatures and provide conclusive evidence that STICs develop in the fallopian tubes.

    Objectives/hypothesis: Sarcomatoid carcinoma of head and neck mucosal sites is a rare malignancy surrounded with much controversy. One factor consistently reported yet not well supported throughout the literature is their relative radioresistance and a general belief that surgery is the treatment of choice. Our objective was to determine if patients treated with radiation for early glottic carcinoma with this histologic diagnosis had worse outcomes than typical squamous cell carcinoma of similar stage. Materials and Methods: Twenty-eight cases of early stage sarcomatoid carcinoma of the larynx treated with definitive doses of megavoltage irradiation between 1969 and 1995 at the University of Texas M.D. Anderson Cancer Center form the cohort for this analysis. All pathologic material was reviewed to confirm the diagnosis. Follow-up ranged from 1.5 - 24 years (median, 10 years). Results: Twenty-one patients were staged T1 and 7 patients had stage T2 disease. Sixteen tumors had the more typical polypoid morphology of sarcomatoid carcinoma. All patients were treated with small laryngeal fields, median size 20 cm2, and to a median dose of 65 Gy. Four patients (14%) had local disease recurrence. All 4 patients had salvage total laryngectomies and remained free of local disease. Only one patient manifested regional and distant disease. The 10-year actuarial survival rate was 63%. Conclusions: Patients with early staged sarcomatoid carcinoma of the glottis treated with radiation had similar control rates to irradiated patients with similar volume disease with the more typical squamous cell carcinoma. We do not believe that the histologic diagnosis of sarcomatoid carcinoma by itself should influence the decision to not treat a patient with early staged glottic disease with irradiation

    Numerous clinical, epidemiological, histological and experimental observations favour the adenoma-carcinoma sequence. Metastases occur only after invasion of the submucosa. The elevated rate of synchronous lesions (carcinomas and adenomas) is emphasized. In the rule, lymphatic spread precedes distant metastasis. Typing and grading should be performed according to the rules of WHO. The present UICC staging system will be replaced by a new 4th edition 1987. Early carcinoma (limited to the submucosa) has an excellent prognosis and may be treated by limited procedures (polypectomy, local excision) in the most cases. The modern concept of histology- and stage-adapted cancer therapy requires the pre-, intra- and postoperative cooperation with the pathologist. (Author)

    Full Text Available Kidney cancer (renal cell carcinoma is one of the major problems of modern urological oncology. In Russia renal cell carcinoma accountsfor 4.3 % of all cancers. The global incidence of renal cell carcinoma has increased over the past two decades. Worldwide renal cell carcinoma accounts for 3.6 % of all cancers and is 10th frequent malignancy. For some malignancies, for instance tumours of prostate, there are markers known that allowed improved early diagnostics. Kidney cancer, however, remains to be hard to diagnose and to treat, since the symptoms can be detected on advanced stages of the disease. In Russia 75.4 % of renal cell carcinoma cases detected at the stage of local and locally advanced disease. Though there are various target drugs on the market aimed to treat this disease, the results of renal cell carcinoma treatment did not reach any substantial success. Most of existing target drugs for kidney cancer treatment include inhibitors of a single signalingpathway regulated by VHL1, which expression is lost in the vast majority of renal-cell carcinomas. Till now existing drugs did not reach sufficient efficacy. Therefore, it is highly important to search for new signaling pathways, regulating such cellular processes as proliferation, migration and apoptosis. Further, prognostic markers and therapy targets identified so far are not sufficient and poorly specific. Therefore identification and validation of new markers, and especially new specific targets for the treatment of kindey oncopathologies is highly important and timely task.

    Children with multiple endocrine neoplasia type 2 (MEN2) often develop medullary carcinoma of the thyroid (MCT) or its precursor, C-cell hyperplasia. Survival results are improved if malignancy is diagnosed early from the results of plasma immunoreactive calcitonin (iCT) measurement. The effect of early detection and thyroidectomy in children with MEN2 syndrome was determined by reviewing the experience between 1975 and 1985. Seventeen children with MEN2 who were 12 years old or younger underwent a total thyroidectomy for MCT or C-cell hyperplasia. iCT was measured in all patients preoperatively and postoperatively. Of the 17 children, 14 (82%) had MEN2a and 3 (18%) had MEN2b. There were 14 (82%) female and three (18%) male patients; their mean age was 6.97 years (range 1.5 to 12 years). In all patients, the diagnosis of MCT was made from initial elevated levels of iCT after stimulation with pentagastrin. Three patients had clinical evidence of disease preoperatively. All patients underwent a total thyroidectomy and lymph nodes were removed from the central zone; a neck dissection was performed in the three with clinically obvious disease. MCT with C-cell hyperplasia was found in 11 children and C-cell hyperplasia alone in six. Of the 11 with carcinoma, eight had bilateral disease and three unilateral. Six children had bilateral C-cell hyperplasia. All 17 children were alive and feeling well at the time of this report; however, three had evidence of metastatic disease according to iCT measurements. None of the children had recurrent nerve injuries; one had evidence of hypoparathyroidism.(ABSTRACT TRUNCATED AT 250 WORDS)

    Medullary carcinoma of the breast is a rare type breast cancer, and shows peculiar clinical features. In a series of 460 cases of breast cancer operated on at the hospital from 1975 to 2004, twelve (2.6%) cases were diagnosed as medullary carcinoma of the breast by postoperative pathological study. When the specimens from the twelve tumors were reevaluated according to the Ridolfi's subtype classification, six tumors were classified into typical medullary carcinoma (TMC) and the remaining six tumors into atypical medullary carcinoma (AMC). On mammography these tumors were visualized as homogeneously enhancing oval masses without calcification and the boundary was comparatively well-defined. US demonstrated well-defied masses with a heterogeneous, hypoechoic texture and with reinforcement of posterior echoes. The rate of lymph node metastasis was 33.3% in medullary carcinomas which was not significantly different from that of infiltrative ductal carcinomas experienced during the same period. The rate of a positivity of a hormone receptor was 8.3% in medullary carcinomas which was low in predominance in comparison with that of infiltrative ductal carcinomas. The positive rate for a HER2/neu (above2+) by the IHC method was 58%. An average observation period is 11 years, and all patients are alive. (author)

    Much of what is known about the significance of human papillomavirus (HPV) in oropharyngeal squamous cell carcinoma is derived from single-institution retrospective studies, post hoc analyses of tissue specimens from clinical trials, and tissue bank studies with a small sample size. The objective of this study is to investigate the impact of HPV on the frequency and clinical presentation of oropharyngeal carcinoma in a large, national sample with information from patients who underwent HPV testing. Retrospective, cross-sectional study. We identified a comprehensive national sample of 8,359 patients with oropharyngeal carcinoma and known HPV status diagnosed between 2010 and 2011 within the National Cancer Database. Multivariable logistic regression was used to assess correlates of patient and tumor characteristics on HPV status. Among patients with oropharyngeal carcinoma, the frequency of HPV-related squamous cell carcinoma in the United States was 65.4%. HPV-related oropharyngeal carcinoma was associated with younger age, male sex, and white race (P presentation (P clinical profile, supporting efforts to re-evaluate the staging and treatment paradigm for HPV-associated oropharyngeal cancer. 4.

    We treat early glottic squamous cell carcinoma with chemoradiation and evaluate the effects of the chemoradiation at the dose of 30-40 Gy as an intermediate evaluation. To investigate the need for this intermediate evaluation, we retrospectively analyzed 97 patients, 92 men and 5 women aged 36 to 86 years, with glottic squamous cell carcinoma at stage I and II treated at our institution from January 2000 to May 2007. The three-year survival rate was 98% in all cases, 100% in T1a, 93% in T1b and 94% in T2. The three-year preservation rate of the larynx was 92% in all cases, 98% in T1a, 93% in T1b and 83% in T2. In the intermediate evaluation, complete response was 78% in T1a, 85% in T1b and 53% in T2. In cases of larynx preservation, the recurrence rate of the primary site was significantly higher in cases without complete response in the intermediate evaluation than in cases with complete response (p<0.05). It seemed that the not complete response case in the intermediate evaluation paid attention to a primary tumor recurrence in particular and needed careful follow-up. (author)

  10. Gingival squamous cell carcinoma: A diagnostic impediment

    2012-01-01

    Full Text Available Oral squamous cell carcinomas represent 3% of cancers in men and 2% of cancers in women. More than 90% of oral cancer occurs in people older than 45 years Lesions of gingiva account for approximately 10% of the oral squamous cell carcinomas and may present clinically as an area of ulceration, exophytic mass, or red/white speckled patches. The proximity to the underlying periosteum may invite early bone invasion. Carcinoma of gingiva constitutes an extremely important group of neoplasms as the lesion frequently mimics the reactive and inflammatory conditions affecting the periodontium, delaying the diagnosis and making the prognosis of the patient poorer. A rare case of gingival squamous cell carcinoma has been reported here, in a 40 Year old male patient. Careful recording of the case history and results of clinical examination, radiographic, and laboratory investigations, along with a critical review of similar conditions led to the diagnosis, and treatment was initiated.

    Full Text Available Abstract Background To date, the clinical presentation and prognosis of mixed ductal/lobular mammary carcinomas has not been well studied, and little is known about the outcome of this entity. Thus, best management practices remain undetermined due to a dearth of knowledge on this topic. Methods In this paper, we present a clinicopathologic analysis of patients at our institution with this entity and compare them to age-matched controls with purely invasive ductal carcinoma (IDC and historical data from patients with purely lobular carcinoma and also stain-available tumor specimens for E-cadherin. We have obtained 100 cases of ductal and 50 cases of mixed ductal/lobular breast carcinoma. Results Clinically, the behavior of mixed ductal/lobular tumors seemed to demonstrate some important differences from their ductal counterparts, particularly a lower rate of metastatic spread but with a much higher rate of second primary breast cancers. Conclusions Our data suggests that mixed ductal/lobular carcinomas are a distinct clinicopathologic entity incorporating some features of both lobular and ductal carcinomas and representing a pleomorphic variant of IDC.

    Full Text Available Abstract Background Carcinoma of the gallbladder (GBC clinically mimics benign gallbladder diseases and often escapes detection until advanced stage. Despite the frequency of cholecystectomy, diagnosis of GBC remains problematic in many situations. We sought to identify pathologic features that contribute to the difficulty in recognition of GBC. Methods We identified 23 patients (ranged from 45 to 86 years, male to female ratio 1:4.5 with carcinoma involving the gallbladder referred to an academic medical center over a period of 10 years for study. This includes 10 cases of primary GBC, 6 cases of metastatic tumor to gallbladder, 6 cases of directly invasive adenocarcinoma arising elsewhere in the biliary tree, and one case of unidentified origin adenocarcinoma. Primary tumors include adenocarcinoma not otherwise specified (NOS in 6 cases, papillary adenocarcinoma in 2 cases, and single cases of undifferentiated carcinoma and combined adenocarcinoma and neuroendocrine carcinoma (NEC. Metastatic tumors to gallbladder were from a wide range of primary sites, predominantly the gastrointestinal tract. Results These cases illustrate seven potential pitfalls which can be encountered. These include: 1 mistakenly making a diagnosis of adenocarcinoma of gallbladder when only benign lesions such as deeply penetrating Rokitansky-Aschoff sinuses are present (overdiagnosis, 2 misdiagnosing well-differentiated invasive carcinoma with minimal disease as benign disease (underdiagnosis, 3 differentiating between primary NEC of gallbladder and metastasis, 4 confusing primary mucinous adenocarcinoma of gallbladder with pseudomyxoma peritonei from a low grade appendiceal neoplasm disseminated to gallbladder, 5 confusing gangrenous necrosis related to cholecystitis with geographic tumoral necrosis, 6 undersampling early, grossly occult disease, and 7 misinterpreting extracellular mucin pools. Conclusions Clinical history and a high index of suspicion are

    Oral cancer in Chile corresponds approximately to 1.6% of all cancer cases. There are few studies about oral epithelial dysplasia and oral squamous cell carcinoma in the Chilean population. To determine the frequency of hyperkeratosis, mild, moderate and severe oral epithelial dysplasia, in situ carcinoma and squamous cell carcinoma of the oral and oropharyngeal mucosa in a registry of the Oral Pathology Reference Institute of the Faculty of Dentistry, Universidad de Chile, in a ten years period. Review of clinical records and pathological plates of 389 patients, obtained between 1990 and 2009. Cases were selected according to their pathological diagnosis, including hyperkeratosis, oral epithelial dysplasia, in situ carcinoma, squamous cell carcinoma and verrucous carcinoma. Forty four percent of cases were squamous cell carcinoma, followed by hyperkeratosis in 37% and mild epithelial dysplasia in 11%. Squamous cell carcinoma was more common in men aged over 50 years. Most of the potentially malignant disorders presented clinically as leukoplakia and squamous cell carcinoma were clinically recognized as cancer. In this study, men aged over 50 years are the highest risk group for oral cancer. Early diagnosis is deficient since most of these lesions were diagnosed when squamous cell carcinoma became invasive. Leukoplakia diagnosis is mostly associated with hyperkeratosis and epithelial dysplasia, therefore biopsy of these lesions is mandatory to improve early diagnosis.

    Purpose: To determine an appropriate clinical target volume for partial breast radiation therapy (PBRT) based on the spatial distribution of residual invasive and in situ carcinoma after wide local excision (WLE) for early breast cancer or ductal carcinoma in situ (DCIS). Methods and Materials: We performed a prospective pathologic study of women potentially eligible for PBRT who had re-excision and/or completion mastectomy after WLE for early breast cancer or DCIS. A pathologic assessment protocol was used to determine the maximum radial extension (MRE) of residual carcinoma from the margin of the initial surgical cavity. Women were stratified by the closest initial radial margin width: negative (>1 mm), close (>0 mm and {<=}1 mm), or involved. Results: The study population was composed of 133 women with a median age of 59 years (range, 27-82 years) and the following stage groups: 0 (13.5%), I (40.6%), II (38.3%), and III (7.5%). The histologic subtypes of the primary tumor were invasive ductal carcinoma (74.4%), invasive lobular carcinoma (12.0%), and DCIS alone (13.5%). Residual carcinoma was present in the re-excision and completion mastectomy specimens in 55.4%, 14.3%, and 7.2% of women with an involved, close, and negative margin, respectively. In the 77 women with a noninvolved radial margin, the MRE of residual disease, if present, was {<=}10 mm in 97.4% (95% confidence interval 91.6-99.5) of cases. Larger MRE measurements were significantly associated with an involved margin (P<.001), tumor size >30 mm (P=.03), premenopausal status (P=.03), and negative progesterone receptor status (P=.05). Conclusions: A clinical target volume margin of 10 mm would encompass microscopic residual disease in >90% of women potentially eligible for PBRT after WLE with noninvolved resection margins.

    Pleomorphic lobular carcinoma is an uncommon form of breast cancer and a subtype of invasive lobular carcinoma. It has unique histopathologic features that translate to a more aggressive phenotype with an associated poor prognosis. Unlike classical invasive lobular carcinoma, it can lose estrogen and progesterone receptor expression and demonstrate HER-2/neu amplification. It remains to be determined, however, whether the pleomorphic histology independently predicts a worse outcome or whether other known associated negative prognostic factors such as larger tumor size, increased metastatic disease, and associated worse molecular subtypes commonly present in pleomorphic carcinoma account for the poor prognosis. Here we present an updated review of the unique pathologic and clinical features of pleomorphic lobular carcinoma needed to guide management for women with this subtype of cancer.

    Brain metastasis from esophageal carcinoma has been considered rare and survival following esophageal carcinoma with distant metastasis is poor. The purpose of this report was to clarify cumulative incidence and risk factors for brain metastasis after chemoradiotherapy for esophageal carcinoma, and to consider recommended treatments for brain metastasis from esophageal carcinoma. We reviewed 391 patients treated with chemoradiotherapy. Median age was 65 years. Clinical stages were I, II, III, and IV in 32, 47, 150, and 162 patients, respectively. Brain imaging was performed usually when patients revealed neurological symptoms. The 3-year cumulative incidence of brain metastasis after chemoradiotherapy was 6.6%. There were 4 patients with single metastasis and 8 with multiple metastases. Initial clinical stages were II, III, and IV in 1, 2, and 9 patients, respectively. Histology included squamous cell carcinoma in 10 patients and others in 2 patients. Univariate analysis demonstrated M factor, distant lymph node relapse, and recurrent lung and liver metastasis as significant risk factors of brain metastasis (P<0.05). Median survival time after diagnosis of brain metastasis was 2.1 months. Brain metastasis was not directly related to cause of mortality. The causes were extracranial tumor deterioration in 8 patients and infection in 4 patients. Brain metastasis may increase in the future with improving survival from esophageal carcinoma. However, considering the poor survival after diagnosis of brain metastasis, short-term palliative therapy for brain metastasis appears preferable to vigorous long-term therapy. (author)

    Forty-four patients of nasopharyngeal carcinoma, treated in Tsukuba University Hospital between March 1988 and March 1998, were reviewed in order to assess the adequacy of our treatment protocol. Most of the cases except 5 were histologically diagnosed as squamous cell carcinoma including 25 of lymphoepithelioma (poorly-differentiated squamous cell carcinoma). Thirty-two out of 39 squamous cell carcinoma cases have fallen into Stage IV category (UICC, 1987) , and all of the non-squamous cell carcinoma cases were also categorized as Stage IV. The basic protocol for nasopharyngeal squamous cell carcinoma was the combination of full-dose irradiation and chemotherapy using cisplatin/carboplatin and peplomycin. The metastatic cervical lymphnodes in 9 cases, too massive to control by this treatment, were surgically dissected after the treatment. Recurrence was noted in 9 cases who were rehospitalized and salvaged medically and/or surgically. As a consequence, the overall 5-year survival rate was 71.4% for squamous cell carcinoma. On the other hand, only one of the 5 non-squamous cell carcinoma cases died of the disease. (author)

    We recently identified a novel histological subtype of hepatocellular carcinoma, designated as "macrotrabecular-massive" (MTM-HCC) and associated with specific molecular features. In order to assess the clinical relevance of this novel variant, we aimed to investigate its prognostic value in two large series of patients with HCC treated either by surgical resection or radiofrequency ablation (RFA). We retrospectively included 237 HCC surgical samples and 284 HCC liver biopsies from patients treated by surgical resection and RFA, respectively. Histological slides were reviewed by pathologists specialized in liver disease, and the MTM-HCC subtype was defined by the presence of a predominant (>50%) macrotrabecular architecture (more than 6 cells thick). The main clinical and biological features were recorded at baseline. Clinical endpoints were early and overall recurrence. The MTM-HCC subtype was identified in 12% of the whole cohort (16% of surgically resected samples, 8.5% of liver biopsy samples). It was associated at baseline with known poor prognostic factors (tumor size, AFP level, satellite nodules and vascular invasion). Multivariate analysis showed that MTM-HCC subtype was an independent predictor of early and overall recurrence (surgical series: OR 3.03 (1.38-6.65), p=0.006 and 2.76 (1.63-4.67), pvalue was retained even after patients stratification according to common clinical, biological and pathological features of aggressiveness. No other baseline parameter was independently associated to recurrence in the RFA series. The MTM-HCC subtype, reliably observed in 12% of patients eligible for a curative treatment, represents an aggressive form of HCC that may require more specific therapeutic strategies.

    Numerous microarray-based prognostic gene expression signatures of primary neoplasms have been published but often with little concurrence between studies, thus limiting their clinical utility. We describe a methodology using logistic regression, which circumvents limitations of conventional Kaplan Meier analysis. We applied this approach to a thrice-analyzed and published squamous cell carcinoma (SQCC) of the lung data set, with the objective of identifying gene expressions predictive of early death versus long survival in early-stage disease. A similar analysis was applied to a data set of triple negative breast carcinoma cases, which present similar clinical challenges. Important to our approach is the selection of homogenous patient groups for comparison. In the lung study, we selected two groups (including only stages I and II), equal in size, of earliest deaths and longest survivors. Genes varying at least four-fold were tested by logistic regression for accuracy of prediction (area under a ROC plot). The gene list was refined by applying two sliding-window analyses and by validations using a leave-one-out approach and model building with validation subsets. In the breast study, a similar logistic regression analysis was used after selecting appropriate cases for comparison. A total of 8594 variable genes were tested for accuracy in predicting earliest deaths versus longest survivors in SQCC. After applying the two sliding window and the leave-one-out analyses, 24 prognostic genes were identified; most of them were B-cell related. When the same data set of stage I and II cases was analyzed using a conventional Kaplan Meier (KM) approach, we identified fewer immune-related genes among the most statistically significant hits; when stage III cases were included, most of the prognostic genes were missed. Interestingly, logistic regression analysis of the breast cancer data set identified many immune-related genes predictive of clinical outcome. Stratification of

    Objective: To investigate the different pattern of neck lymph node metastasis, the choice of surgical methods and prognosis in early tongue squamous cell carcinoma. Methods: A total of 157 patients with early oral tongue squamous cell carcinoma were included in this study. Statistical analysis was performed to identify the pattern of lymph node metastasis, to determine the best surgical procedure and to analyze the prognosis. Results: The occurrence of cervical lymph node metastasis rate was 31%(48/157). Neck lymphatic metastasis was significantly related to tumor size ( P= 0.026) and histology differentiation type ( P= 0.022). The rate of metastasis was highest in level Ⅱ [33% (16/48)]. In level Ⅳ, the incidence of lymph node metastasis was 5%(7/157), and there was no skip metastases. The possibility of level Ⅳ metastasis was higher, when level Ⅱ ( P= 0.000) or Ⅲ ( P= 0.000) involved. The differentiation tumor recurrence, neck lymphatic metastasis and adjuvant radiotherapy were prognostic factors ( Psquamous cell carcinoma, simultaneous glossectomy and neck dissection should be performed. Level Ⅳ metastasis rate is extremely low, so supraomohyoid neck dissection is sufficient for most of the time. The histology differentiation type, neck lymphatic metastasis and adjuvant radiotherapy are independent prognostic factors.

    Endometrial carcinoma is one of the most common gynecologic malignancies and which is predominant in postmenopausal women. Clinically many patients are hospitalized in early stage due to clinical sign and symptom such as vaginal bleeding and in this case, patient's prognosis is known to be good. However, considerable number of patients with advanced and relapsed disease reveal poor prognosis. Therefore, exact staging work up is essential for proper treatment as is primary lesion detection. 18 F-FDG-PET has been widely used for the evaluation of gynecologic malignancies such as cervical carcinoma and ovarian cancer. In contrast, FDG PET application to endometrial carcinoma is limited until now and there is no sufficient data to validate the usefulness of FDG PET for this disease yet. However, several studies showed promising results that FDG PET is sensitive and specific in detection of recurrent or metastatic lesions. Therefore further active investigation in this field can facilitate the use of FDG PET for endometrial carcinoma

    In patients with early cervix carcinoma, both radiotherapy and surgery or combined modalities provide effective therapies. In the two last modalities, recommended surgery is radical hysterectomy. The purpose of this prospective study was to assess the value of a limited vaginal hysterectomy after brachytherapy in patients without any unfavorable prognostic factor. Twenty-two patients (stage la2 with vascular invasion: three patients, stage lb1:19 patients) with 1 cm median maximal tumor size and with previous negative laparoscopic lymphadenectomy (median number of lymph nodes:12) underwent a limited vaginal hysterectomy 6 weeks after utero-vaginal brachytherapy. Two mild intra-operative complications were noted. Venous hemorrhage (100 mL) occurred in one patient during lymphadenectomy and another patient presented bladder injury during hysterectomy. These two complications were successfully controlled with no need for laparotomy. Only one late complication was observed: bladder grade G2(b). With a 29 months follow-up (20-48 months), no recurrence was reported. These results appear promising in patients with very early cervix carcinoma but remain to be confirmed on a larger scale.

It accounts for less than 1% of all urinary bladder carcinomas. The purpose of this study is to review the clinical features, the treatment modalities, and the overall survival of these patients. We also compare the clinical outcomes between patients of bladder small cell carcinoma (SCC and bladder urothelial carcinoma (UC. Materials and methods: We reviewed the charts of patients with bladder tumors from January 1995 to December 2012 in the Chang Gung Memorial Hospital. A total of 2421 malignant bladder tumor patients were reviewed and there were 18 patients who were diagnosed with primary bladder SCC. The patients' characteristics, including age, gender, smoking history, presented symptoms, tumor size, locations, clinical stages, treatment modalities, pathology appearance, recurrence conditions, and survival conditions were all recorded. We also compared the clinical outcomes and the overall survival rates between patients with bladder SCC and those with UC. Results: Bladder SCC accounted for about 0.74% of all bladder malignancies in our institution. The mean age at diagnosis was 70.67 years, and the male-to-female ratio was 2.6:1. Thirteen patients had a history of cigarette smoking. All patients presented with symptoms of gross hematuria, and three of them had bladder tamponade requiring blood clot evacuation by cystoscopy. Only one patient had T1 disease, ten patients had stage III disease, and seven patients had lymph node or distant metastasis (stage IV disease. The mean tumor size was 4.29 cm in diameter. For the majority (61.11% of patients, SCC coexisted with UC components. The average survival time

    Full Text Available Appendiceal diverticulosis is a rare condition. Herein reported is a case of appendiceal diverticulosis and diverticulitis clinically masquerading as appendiceal carcinoma. A 62-year-old woman presented with abdominal pain. US and CT showed a tumor measuring 5 × 4 × 4 cm in vermiform appendix. Colon endoscopy showed mucosal elevation and irregularity in the orifice of vermiform appendix. A biopsy of the appendiceal mucosa showed no significant changes. Clinical diagnosis was appendiceal carcinoma and wide excision of terminal ileum, appendix, cecum, and ascending colon was performed. Grossly, the appendix showed a tumor measuring 5 × 3 × 4 cm. The appendiceal lumen was opened, and the appendiceal mucosa was elevated and irregular. The periappendiceal tissue showed thickening. Microscopically, the lesion was multiple appendiceal diverticula. The diverticula were penetrating the muscle layer. The mucosa showed erosions in places. Much fibrosis, abscess formations, and lymphocytic infiltration were seen in the subserosa. Abscesses were also seen in the diverticular lumens. Some diverticula penetrated into the subserosa. The pathologic diagnosis was appendiceal diverticulitis. When they encounter an appendiceal mass, clinicians should consider appendiceal diverticulitis as a differential diagnosis.

    From 1/1985 to 7/1993, 18 patients underwent endoscopic photodynamic therapy (PDT) for early stage esophageal squamous cell carcinoma -- as two patients had two synchronous esophageal cancers, 20 lesions were treated. Tumors were staged as Tis in 7 cases and T1 in 13. The average light energy delivered was 50 J/cm2 and 70 J/cm2 for the treatment of Tis and T1, respectively. To obtain a more uniform distribution of laser light in 12 cases the irradiation was performed through the wall of a transparent tube previously placed over the endoscope and advanced into the stomach. The overall results show a complete response in 14/20 (70%) tumors. Three patients developed a local recurrence, 6, 12, and 14 months after therapy. After a follow-up of 5 to 75 months, there was no evidence of disease in 10/18 patients (56%). The actuarial survival rate was 95%, 79%, and 26% at 1, 3, and 5 years, respectively. Complications were skin reaction in one patient and esophageal stenosis at the treatment site, that gradually responded to endoscopic bougienage, in 2 patients. Endoscopic PDT proved to be safe and effective in the treatment of superficial carcinoma of the esophagus.

    Thirty-two patients with hepatocellular carcinoma and six patients with renal cell carcinoma for whom the arterial embolization therapy was performed were studied by CT and clinical follow-up for investigating intratumoral gas detected on CT in post-embolization cases. The intratumoral air was found by CT in seven patients with hepatocellular carcinoma and four patients with renal cell carcinoma. The air was composed of a collection of multiple small round gas bubbles in the embolized tumor except in one case where it formed a serpiginous pattern. There was no hematologic nor clinical evidence of liver abscess in all the cases. It was possible to distinguish gas from abscess or fat by a combination of CT and clinical findings.

    We present a clinical case of 9 years old girl with concomitant brain tumors - choroid plexus carcinoma and craniopharyngioma diagnosed in 2009. After three operations, cranio-spinal irradiation with boost for the remaining tumor located in left ventricular trigonum to a total dose of 55 Gy and 7 courses chemotherapy, local tumor control was achieved for the choroid plexus carcinoma. Four years following the achievement of local tumor control of the choroid plexus carcinoma, an increase of the tumor formation located in the left side of the pituitary was reported. The diagnosis cystic craniopharyngeoma was found during the surgical operation. With this clinical case we would like to stress on the achieved local tumor control following the complex treatment of carcinoma of the choroid plexus, as well as on the slow growth of simultaneously diagnosed craniopharyngeoma. This case report raises the question of the genetic predisposition of the brain tumors in children, as well as possibility of malignant transformation of craniopharyngeoma following radiotherapy. The differential diagnosis of neuroectodermal brain tumors requires immunohistochemical analysis and if necessary genetic analysis. Key words: Complex treatment. Choroid plexus carcinoma.

    Purpose: Early squamous cell carcinoma of the hypopharynx is a rare clinical entity. Our objective was to analyze the outcome of patients with early hypopharyngeal cancer treated with curative radiotherapy or the combination of preoperative radiotherapy with surgery. Methods and Materials: Forty-three patients with Stage I-II hypopharyngeal cancer were initially treated with 30-40 Gy of irradiation with or without chemotherapy. Thirty-two patients (74.4%) who demonstrated a complete response continued to receive further radiotherapy, with a median total dose of 61.2 Gy. Eleven other patients (25.6%) received surgery. Results: Local control with laryngeal voice preservation was achieved in 8 (88.9%) of 9 patients with Stage I disease, and in 23 (67.6%) of 34 patients with Stage II disease. The overall and disease-specific 5-year survival rates for all patients were 70.4% and 89.5%, respectively. The disease-specific survival rates according to the T-category were 100% for patients with T1 disease and 87.2% for patients with T2 disease (p = 0.32). Twenty patients (46.5%) had synchronous or metachronous cancers. Four patients died of hypopharyngeal cancer, and 5 died of second-primary esophageal cancer. Conclusions: A majority of patients with early hypopharyngeal cancer was curable. However, second malignancies influenced the overall outcome of patients with early hypopharyngeal cancer

    Full Text Available Halo phenomenon of nevus may be observed as a circular reaction, although it is unusual around tumors. A 29-year-old woman presented with a pigmented lesion on the cheek since three years. She noted whitening of the skin around the lesion almost after a year following its appearance. Dermatologic examination revealed a pigmented nodular lesion with a hypopigmented halo on the left infraorbital region. The clinical impression was halo nevus, whereas basal cell carcinoma (BCC was considered in dermatoscopic differential diagnosis. The diagnosis was infiltrative-type BCC histopathologically. The persistence of a perilesional halo around an enlarging pigmented lesion should be carefully examined with accompanying dermatoscopic findings even in young patients for early diagnosis of tumoral lesions.

    Full Text Available Abstract Purpose To evaluate the clinical efficacy and toxicity of stereotactic body radiation therapy (SBRT using extracranial gamma knife in patients with mainly bulky inoperable early stage non-small cell lung carcinoma (NSCLC. Materials and methods A total of 43 medically inoperable patients with mainly bulky Stage I/II NSCLC received SBRT using gamma knife were reviewed. The fraction dose and the total dose were determined by the radiation oncologist according to patients' general status, tumor location, tumor size and the relationship between tumor and nearby organ at risk (OAR. The total dose of 34~47.5 Gy was prescribed in 4~12 fractions, 3.5~10 Gy per fraction, one fraction per day or every other day. The therapeutic efficacy and toxicity were evaluated. Results The median follow-up was 22 months (range, 3-102 months. The local tumor response rate was 95.35%, with CR 18.60% (8/43 and PR 76.74% (33/43, respectively. The local control rates at 1, 2, 3, 5 years were 77.54%, 53.02%, 39.77%, and 15.46%, respectively, while the 1- and 2-year local control rates were 75% and 60% for tumor ≤3 cm; 84% and 71% for tumor sized 3~5 cm; 55% and 14.6% for tumor sized 5~7 cm; and 45%, 21% in those with tumor size of >7 cm. The overall survival rate at 1, 2, 3, 5 years were 92.04%, 78.04%, 62.76%, 42.61%, respectively. The toxicity of stereotactic radiation therapy was grade 1-2. Clinical stages were significantly important factor in local control of lung tumors (P = 0.000. Both clinical stages (P = 0.015 and chemotherapy (P = 0.042 were significantly important factors in overall survival of lung tumors. Conclusion SBRT is an effective and safe therapy for medically inoperable patients with early stage NSCLC. Clinical stage was the significant prognostic factors for both local tumor control and overall survival. The toxicity is mild. The overall local control for bulky tumors is poor. Tumor size is a poor prognostic factor, and the patients for

    Purpose: To investigate the potential utility of in-line phase-contrast imaging (ILPCI) technique with synchrotron radiation in detecting early hepatocellular carcinoma and cavernous hemangioma of live using in vitro model system. Methods: Without contrast agents, three typical early hepatocellular carcinoma specimens and three typical cavernous hemangioma of live specimens were imaged using ILPCI. To quantitatively discriminate early hepatocellular carcinoma tissues and cavernous hemangioma tissues, the projection images texture feature based on gray level co-occurrence matrix (GLCM) were extracted. The texture parameters of energy, inertia, entropy, correlation, sum average, sum entropy, difference average, difference entropy and inverse difference moment, were obtained respectively. Results: In the ILPCI planar images of early hepatocellular carcinoma specimens, vessel trees were clearly visualized on the micrometer scale. Obvious distortion deformation was presented, and the vessel mostly appeared as a ‘dry stick’. Liver textures appeared not regularly. In the ILPCI planar images of cavernous hemangioma of live specimens, typical vessels had not been found compared with the early hepatocellular carcinoma planar images. The planar images of cavernous hemangioma of live specimens clearly displayed the dilated hepatic sinusoids with the diameter of less than 100 microns, but all of them were overlapped with each other. The texture parameters of energy, inertia, entropy, correlation, sum average, sum entropy, and difference average, showed a statistically significant between the two types specimens image (P<0.01), except the texture parameters of difference entropy and inverse difference moment(P>0.01). Conclusion: The results indicate that there are obvious changes in morphological levels including vessel structures and liver textures. The study proves that this imaging technique has a potential value in evaluating early hepatocellular carcinoma and cavernous

    Full Text Available Basal cell carcinoma (BCC is the most common paraneoplastic disease among human neoplasms. The tumor affects mainly photoexposed areas, most often in the head and seldom appears on genitalia and perigenital region. BCC progresses slowly and metastases are found in less than 0.5% of the cases; however, a considerable local destruction and mutilation could be observed when treatment is neglected or inadequate. Different variants as nodular, cystic, micronodular, superficial, pigment BCC are described in literature and the differential diagnosis in some cases could be difficult. The staging of BCC is made according to Tumor, Node, Metastasis (TNM classification and is essential for performing the adequate treatment. Numerous therapeutic methods established for treatment of BCC, having their advantages or disadvantages, do not absolutely dissolve the risk of relapses. The early diagnostics based on the good knowledge and timely organized and adequate treatment is a precondition for better prognosis. Despite the slow progress and numerous therapeutic methods, the basal cell carcinoma should not be underestimated.

    Squamous cell carcinoma ofthe anal canal represents 1.5% of all malignancies affectingthe gastrointestinal tract. Over the past 20 years dramatic changes have been seen in both the epidemiological distribution of the disease and in the therapeutic modalities utilised to manage it. CLINICAL MANAGEMENT: Historically abdominoperineal resection had been the treatment of choice with local resection reserved for early stage disease. Work by Nigro et al. has revolutionised how we currently manage carcinoma of the anal canal, demonstrating combined modality chemoradiotherapy as an appropriate alternative to surgical resection with the benefit of preserving sphincter function. Surgery is then reserved for recurrent disease with salvage abdominoperineal resection. This article reviews current literature and highlights the changing therapeutic modalities with selected clinical cases

    Full Text Available Cutaneous squamous cell carcinomas (SCC affecting the regions of the head and neck can be challenging to resect surgically and refractory to chemotherapy or radiation therapy. Consequently; the treatment of squamous cell carcinomas of the skin is a focus of current research. One such advancement is immunotherapy. Herein we describe clinical remission of invasive, poorly differentiated squamous cell carcinoma of the pre-auricular region with external auditory canal involvement using cetuximab, an epidermal growth factor receptor (EGFR antibody; and nivolumab, a programmed death receptor-1 (PD-1 antibody. Such durable and comprehensive disease resolution demonstrates the therapeutic potential of cetuximab and nivolumab in surgically challenging, treatment-resistant cutaneous squamous cell carcinoma.

    Verrucous carcinoma (VC) is an exophytic, low-grade, well-differentiated variant of squamous cell carcinoma. It is described as a lesion appearing in the sixth or seventh decade of life that has minimal aggressive potential and, in long-standing cases, has been shown to transform into squamous cell carcinoma. Oral submucous fibrosis (OSMF) is a potentially malignant disorder, and about one-third of the affected population develop oral squamous cell carcinoma. The histopathological diagnosis of verrucous carcinoma is challenging, and the interpretation of early squamous cell carcinoma requires immense experience. Here we present a rare case of a 24-year-old male with OSMF transforming to verrucous carcinoma with invasive squamous cell carcinoma. Even though the case had a straightforward clinical diagnosis, the serial sectioning done for pathological diagnosis disclosed the squamous cell carcinoma.

    Full Text Available The simultaneous association of gastric carcinoma with omental mucosa-associated lymphoid tissue (MALT lymphoma is a rare event that has not been reported previously. We focused on the hypothetic pathogenetic mechanisms, diagnosis and treatment of this rare condition. A 55-year-old woman with Helicobacter pylori infection underwent distal gastrectomy in our hospital. Three independent early gastric cancers and a mass near the cecum were diagnosed preoperatively. Pathological review of the resected stomach showed three independent early signet ring cell gastric carcinomas, and the mass in the omentum near the cecum was shown to be omental MALT lymphoma. Due to the nature of the patient's disease, she was started on medical eradication of H. pylori. Synchronous gastric adenocarcinoma and omental MALT lymphoma is a rare event. Special attention given to H. pylori-associated gastric cancer patients can avoid misdiagnosis and lead to adequate treatment.

    Patients with chronic hepatitis C who achieve a sustained viral response after pegylated interferon therapy have a reduced risk of hepatocellular carcinoma, but the risk after treatment with direct-acting antivirals is unclear. We compared the rates of early development of hepatocellular carcinoma after direct-acting antivirals and after pegylated interferon therapy. We retrospectively analysed 785 patients with chronic hepatitis C who had no history of hepatocellular carcinoma (211 treated with pegylated interferon, 574 with direct-acting antivirals) and were followed up for at least 24 weeks after antiviral treatment. De novo hepatocellular carcinoma developed in 6 of 574 patients receiving direct-acting antivirals and in 1 of 211 patients receiving pegylated interferon. The cumulative incidence of early hepatocellular carcinoma development did not differ between the treatment groups either for the whole cohort (1.05% vs 0.47%, P = .298) or for those patients with Child-Pugh Class A cirrhosis (3.73% vs 2.94%, P = .827). Multivariate analysis indicated that alpha-fetoprotein level >9.5 ng/mL at the time of end-of-treatment response was the only independent risk factor for early development of hepatocellular carcinoma in all patients (P hepatocellular carcinoma did not differ between patients treated with pegylated interferon and those treated with direct-acting antivirals and was associated with the serum alpha-fetoprotein level at the time of end-of-treatment response. © 2018 John Wiley & Sons Ltd.

    Mutation status of the KRAS gene identifies a distinct disease subtype of metastatic colorectal carcinoma that does not respond to antibody therapeutics targeting the epidermal growth factor receptor. This is currently the only validated marker in metastatic colorectal carcinoma with a clear implication in treatment selection. KRAS testing is widely accepted in clinical practice to guide metastatic colorectal carcinoma therapeutic decisions, and there are many commercially available platforms to perform the test. To evaluate the critical role of pathologists in the full implementation of KRAS testing by optimizing tumor tissue collection and fixation procedures and by choosing testing technologies and reliable Clinical Laboratory Improvement Amendments of 1988-certified laboratories to perform the tests. Prospective clinical trials, retrospective studies, and quality assessment and survey reports were identified in the following databases: PubMed, American Society of Clinical Oncology Proceedings (American Society of Clinical Oncology Annual Meeting and Gastrointestinal Cancer Symposium) and European Society for Medical Oncology Proceedings (Annals of Oncology European Society for Medical Oncology Congress and Annals of Oncology World Congress on Gastrointestinal Cancers). More bona fide standards are needed to address the variety of available test methods, which have different performance characteristics including speed, sensitivity to detect rare mutations, and technical requirements. Refined standards addressing timing of KRAS testing, laboratory performance and accuracy, quality assurance and control, proper tissue collection, and appropriate result reporting would also be greatly beneficial. Pathologists should be aware that the amount of information they need to manage will increase, because future trends and technological advances will enhance the predictive power of diagnostic tests or the scope of the biomarker panels tested routinely across tumor types.

    Merkel cell carcinoma is a rare and aggressive neoplasm originating from mechanoreceptor Merkel cells of the stratum basale of the epidermis. Cases affecting the vulva are exceedingly rare, with the currently available literature primarily in case report form. Systematic review of the PubMed database returned 17 cases of Merkel cell carcinoma affecting the vulva. Patients presented at a mean age of 59.6 years with a firm, mobile vulvar mass. Symptoms of pain, erythema, pruritus, edema, and ulceration have been reported. Tumor histology is consistent with that of neuroendocrine tumors and typical Merkel cell carcinomas. Neuroendocrine and cytokeratin immunostains are frequently utilized in histopathological workup. Surgical management was the unanimous first-line therapy with adjuvant radiation in most cases. Recurrence occurred in 70.6% of patients at a mean follow-up of 6.3 months. Mortality was at 47.0% at a mean of 7.8 months after initial operation. Merkel cell carcinoma affecting the vulva is an extremely rare and highly aggressive neoplasm. The present review of published cases serves to comprehensively describe the clinical course and treatment approaches for vulvar Merkel cell carcinoma.

    Accurate clinical staging is important for patient counseling, treatment planning, prognostication, and rational design of clinical trials. In head and neck squamous cell carcinoma, discrepancy between clinical and pathological staging has been reported. To evaluate any disparity between clinical and pathological tumor-node-metastasis (TNM) staging in oral cavity squamous cell carcinoma (OCSCC) patients and any impact of the same on survival. Retrospective chart review from year 2007 to 2013, at a tertiary care center. All survival analyses were performed using SPSS for Windows version 15 (Chicago, IL, USA). Disease-free survival curves were generated using Kaplan-Meier algorithm. One hundred and twenty-seven patients with OCSCC were analyzed. Seventy-nine (62.2%) were males and 48 (37.8%) females with a mean age at presentation 43.6 years (29-79 years). The highest congruence between clinical and pathological T-staging seen for clinical stage T1 and T4 at 76.9% and 73.4% with pathological T-stage. Similarly, the highest congruence between clinical and pathological N-stage seen for clinical N0 and N3 at 86.4% and 91.7% with pathological N-stage. Of clinically early stage patients, 67.5% remained early stage, and 32.5% were upstaged to advanced stage following pathological analysis. Of the clinically advanced stage patients, 75% remained advanced, and 25% were pathologically downstaged. This staging discrepancy did not significantly alter the survival. Some disparity exists in clinical and pathological TNM staging of OCSCC, which could affect treatment planning and survival of patients. Hence, more unified and even system of staging for the disease is required for proper decision-making.

    Clinical features of multiple squamous cell carcinoma (SCC) cases within the head and neck that were treated in our department during the recent 10 years are discussed. Multiple SCCs arose in 6.6% of the cases with primary SCC; 67% of the cases had two carcinomas, and 33% had more than three carcinomas. The most common site of the multiple SCCs was the oral cavity (54%). The most frequent interval between treatment of previous carcinoma and diagnosis of subsequent carcinoma was simultaneous, but more than 5 years' interval was observed in 36% of the patients. The most common initial treatment of the carcinoma was irradiation, but the ratio of surgery increased for subsequent carcinomas. Prognosis of the patients with more than three carcinomas was not worse than that of patients with two carcinomas. Therefore, early diagnosis of the subsequent carcinomas based on careful long-term observation in the head and neck is necessary for follow-up of the patients with SCC of the head and neck. Treatment strategies considering the treatment of subsequent carcinomas are needed for the patients with primary head and neck SCC. (author)

    The Gorlin-Goltz syndrome, also known as nevoid basal cell carcinoma syndrome (NBCCS), is an infrequent multisystemic disease inherited in a dominant autosomal way, which shows a high level of penetrance and variable expressiveness. It is characterized by odontogenic keratocysts in the jaw, multiple basal cell nevi carcinomas and skeletal abnormalities. This syndrome may be diagnosed early by a dentist by routine radiographic exams in the first decade of life, since the odontogenic keratocysts are usually one of the first manifestations of the syndrome. This case report presents a patient diagnosed as NBCCS by clinical, radiographic and histological findings in a 13-year-old boy. This paper highlights the importance of early diagnosis of NBCCS which can help in preventive multidisciplinary approach to provide a better prognosis for the patient.

    Invasive lobular carcinoma of the breast is the second most common type of primary breast cancer, accounting for 8-14% of cases, but is often difficult to diagnose early. It typically shows a diffuse pattern of infiltration within the breast, resulting in a variety of often subtle radiological appearances. A similar infiltrative pattern is seen in its metastatic form, with involvement of the gastrointestinal tract, peritoneum, retroperitoneum, bone marrow, meninges and uterus occurring more frequently than with the more common infiltrating ductal carcinoma of the breast. This pictorial essay illustrates the spectrum of radiological appearances which may be encountered with both primary and secondary lobular carcinoma. Harake, M.D.J., Maxwell, A.J. and Sukumar, S.A.

    The incidence of occult perifacial nodal disease in oral cavity squamous cell carcinoma is not well reported. The purpose of this study was to evaluate the incidence of isolated perifacial lymph node metastasis in patients with oral squamous cell carcinoma with a clinically node-negative neck. The study will shed light on current controversies and will provide valuable clinical and pathological information in the practice of routine comprehensive removal of these lymph node pads in selective neck dissection in the node-negative neck. Prospective analysis. This study was started in August 2011 when intraoperatively we routinely separated the lymph node levels from the main specimen for evaluation of the metastatic rate to different lymph node levels in 231 patients of oral squamous cell cancer with a clinically node-negative neck. The current study demonstrated that 19 (8.22%) out of 231 patients showed ipsilateral isolated perifacial lymph node involvement. The incidence of isolated perifacial nodes did not differ significantly between the oral tongue (7.14%) and buccal mucosa (7.75%). Incidence was statistically significant in cases with lower age group (oral squamous cell carcinoma with a clinically node-negative neck. The incidence of isolated perifacial involvement is high in cases of buccal mucosal and tongue cancers. A meticulous dissection of the perifacial nodes seems prudent when treating the neck in oral cavity squamous cell carcinoma. 4 Laryngoscope, 126:2252-2256, 2016. © 2016 The American Laryngological, Rhinological and Otological Society, Inc.

    Background and purpose: The management of lymphatic metastasis of early-stage oral tongue carcinoma patients is crucial for its prognosis. The purpose of this study was to evaluate the predictive ability of lymphatic metastasis after brachytherapy (BRT) for early-stage tongue carcinoma based on gene expression profiling. Patients and methods: Pre-therapeutic biopsies from 39 patients with T1 or T2 tongue cancer were analyzed for gene expression signatures using Codelink Uniset Human 20K Bioarray. All patients were treated with low dose-rate BRT for their primary lesions and underwent strict follow-up under a wait-and-see policy for cervical lymphatic metastasis. Candidate genes were selected for predicting lymph-node status in the reference group by the permutation test. Predictive accuracy was further evaluated by the prediction strength (PS) scoring system using an independent validation group. Results: We selected a set of 19 genes whose expression differed significantly between classes with or without lymphatic metastasis in the reference group. The lymph-node status in the validation group was predicted by the PS scoring system with an accuracy of 76%. Conclusions: Gene expression profiling using 19 genes in primary tumor tissues may allow prediction of lymphatic metastasis after BRT for early-stage oral tongue carcinoma

    The biological behavior of ulcer type gastric carcinoma was studied on 114 cases of diffuse carcinoma (Borrmann's 4 type) and 262 cases of early like advanced carcinoma (including superficial spreading type). In both types of gastric carcinoma, the age distribution, location, ulcer with cancer focus and prognosis differed greatly. The early like carcinoma was speculated to have advanced maintaining the groos findings of early gastric carcinoma, and its location and associated ulcer were the same as the early ulcer type of carcinoma. The prognosis of this type of carcinoma was good, showing a figure of 70% in 3 year survival rate. On the other hand, diffuse carcinoma demonstrated diffuse extensive infiltration of tumor cells along the gastric wall, resulting in poor prognosis with a 3 year survival rate of almost 0%. Histologically, diffuse type of carcinoma showed lymphatic infiltration of tumor cells, and this is probably the main reason for the diffuse infiltration in this type of carcinoma. Diffuse carcinoma is, therefore, considered to be one special type of carcinoma having different biological behavior compared with the other ulcer type of carcinoma, and diffuse carcinoma is not the terminal stage of early like advanced carcinoma. There are three stages in diffuse carcinoma: 1. Infiltrative stage: wide spread infiltration of cancer cells through lymphatic channels (lymphangiosis carcinomatosa) 2. Edematous stage: soluble collagen appearing in gastric wall 3. Sclerosing stage: soluble collagen changing into insoluble collagen leading to marked thickening and stiffness of the gastric wall. This is the end stage of gastric diffuse carcinoma. It is difficult to explain that the marked fibrosis of gastric wall is a result to stromal reaction from tumor cell infiltration, since extensive fibrosis is found in areas without tumor cells and stiffness of the gastric wall occurs in a too short period of time. The production of abundunt soluble collagen is probably

    Full Text Available Abstract Background Cyclin E and p27 expression is easy to assess in human tissues by standard immunohistochemical techniques. Immunohistochemistry is cost effective, relatively easy to perform and will play more of a role in the future management of cancer. The aim of this study was to investigate the role of p27 and cyclin E immunoexpression as a prognostic factor in early breast carcinoma. Methods Cyclin E and p27 immunohistochemistry was performed on sixty six cases of breast carcinoma submitted over a five year period to the Division of Anatomical Pathology, Groote Schuur hospital; Whittaker and Associates; and PathCare. All tumours included in this study were less than 5 cm in diameter (pT1 and pT2 stage and all the patients had wide local excisions performed. Follow up information was obtained from patient folders in the Department of Radiation Oncology. Results There was no significant association of cyclin E and p27 expression with distant metastasis free survival (MFS for all invasive carcinomas in contrast to grade, lymph node spread and vascular invasion. However, there was a statistically significant direct association of cyclin E with distant metastases in all invasive carcinomas, in the subgroup of infiltrating duct carcinomas (IDC and in the node negative group when cyclin E was stratified as negative and positive (low/high. In this study of early breast carcinoma, only 9/66 cases showed cyclin E expression. Of these, four patients had distant metastases, one patient had a local recurrence and four patients were alive at last follow-up. Furthermore, cyclin E expression was significantly associated with grade, lymph node spread, oestrogen receptor status and histological type. None of the lobular carcinomas showed cyclin E positivity and only one case of lobular carcinoma presented with distant metastases. 59/66 cases were positive (low/high for p27 while seven cases were negative, 22 cases showed low expression and 37 cases

    Male breast carcinoma accounts for 1% of all diagnosed breast carcinoma. Pure ductal carcinoma in situ in men is extremely rare. Unfortunately, male breast cancer is often diagnosed at a late stage because of the minimal awareness of presenting symptoms by the patient and sometimes by the health care provider. Because of this late presentation, the overall prognosis is less favorable. This case is presented to emphasize the importance of recognizing bloody nipple discharge as a clinical sign of male ductal carcinoma in situ and an opportunity for early diagnosis.

    In ulcerative colitis (UC), the majority of colorectal carcinomas (CRC) arise in the vast colorectal mucosal domain built with mucus-producing goblet cells and columnar cells. Conversely, CRC in UC rarely evolve in the tiny, spotty gut-associated lymphoid tissue (GALT) mucosal domain. Here we review the four reported cases of colonic carcinoma developing in GALT mucosa in UC, searching for possible precursor lesions connected with the evolution of these tumours. The clinical history, age, gender, endoscopic descriptions, and the pathology (localization, gross and histological descriptions of the luminal surface) of the four UC-GALT carcinomas reported in the literature were reviewed. The luminal surface in three out of the four carcinomas revealed conventional (tubular/villous) adenomas or high-grade dysplasia. All four UC-GALT-carcinomas were detected at an early stage (T1N0). GALT carcinomas do occur, albeit infrequently, in patients with UC. The finding that three out of the four GALT carcinomas on record were covered by conventional adenomas or by high-grade dysplasia strongly suggests that non-invasive conventional neoplasias might often precede GALT carcinomas in UC.

    Objective: The purpose of our study was to describe the clinical features, imaging characteristics, pathologic findings and outcome of microinvasive ductal carcinoma in situ (DCISM). Materials and methods: The records of 21 women diagnosed with microinvasive ductal carcinoma in situ (DCISM) from November 1993 to September 2006 were retrospectively reviewed. The clinical presentation, imaging and histopathologic features, and clinical follow-up were reviewed. Results: The 21 lesions all occurred in women with a mean age of 56 years (range, 27-79 years). Clinical findings were present in ten (48%): 10 with palpable masses, four with associated nipple discharge. Mean lesion size was 21 mm (range, 9-65 mm). The lesion size in 62% was 15 mm or smaller. Mammographic findings were calcifications only in nine (43%) and an associated or other finding in nine (43%) [mass (n = 7), asymmetry (n = 1), architectural distortion (n = 1)]. Three lesions were mammographically occult. Sonographic findings available in 11 lesions showed a solid hypoechoic mass in 10 cases (eight irregular in shape, one round, one oval). One lesion was not seen on sonography. On histopathologic examination, all lesions were diagnosed as DCISM, with a focus of invasive carcinoma less than or equal to 1 mm in diameter within an area of DCIS. Sixteen (76%) lesions were high nuclear grade, four (19%) were intermediate and one was low grade (5%). Sixteen (76%) had the presence of necrosis. Positivity for ER and PR was noted in 75% and 38%. Nodal metastasis was present in one case with axillary lymph node dissection. Mean follow-up time for 16 women was 36 months without evidence of local or systemic recurrence. One patient developed a second primary in the contralateral breast 3 years later. Conclusion: The clinical presentation and radiologic appearance of a mass are commonly encountered in DCISM lesions (48% and 57%, respectively), irrespective of lesion size, mimicking findings seen in invasive carcinoma

    LncRNA RGMB-AS1 has been suggested to play significant roles in lung cancer progression. However, it remains unknown whether lncRNA RGMB-AS1 is involved in the development and progression of hepatocellular carcinoma. In our results, lncRNA RGMB-AS1 was low-expressed in hepatocellular carcinoma tissues and cell lines, and associated with clinical stage, tumor size and metastasis. Survival analysis indicated that lncRNA RGMB-AS1 high was an independent favorable prognostic factor for hepatocellular carcinoma patients. Gain-of-function studies showed up-regulated lncRNA RGMB-AS1 expression suppressed hepatocellular carcinoma cells proliferation, migration and invasion, and promoted cells apoptosis. There was a positively association between lncRNA RGMB-AS1 and RGMB in hepatocellular carcinoma tissues, and up-regulated lncRNA RGMB-AS1 expression increased RGMB mRNA and protein expressions in hepatocellular carcinoma cells. In conclusion, lncRNA RGMB-AS1 serves an anti-oncogenic role in hepatocellular carcinoma. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

    The treatment of the laryngeal carcinoma is controversial in the otolaryngology literature; in glottis cancer that can be managed with radiotherapy, conservative laryngeal surgery and micro-endoscope by laser. At present time, the main objective in the treatment of the early glottis cancer is the control of the tumor and preservation of a good voice. In small injuries, the surgery and the radiotherapy offer equivalent cure rates. The handling of the failure of radiotherapy is controversial; the options go from the resection endoscope with laser, to the total laryngectomy, with local controls [es

    A review of 156 cases of renal cell carcinoma diagnosed during a 20-year period demonstrated the changes of initial signs/symptoms and imaging modalities for detection and definition. According to the imaging modality used for diagnosing renal cell carcinoma, clinical pictures were chronologically examined over 4 periods: 1973 to 1979 (before CT era), 1980 to 1984 (early CT era), 1985 to 1987 (CT era) and 1988 to 1992 (CT/MRI era). With regards to initial signs or symptoms, the proportion of classical trials has gradually decreased, while that of tumors noted incidentally has increased. As for imaging modalities for detection, the proportion of IVP has gradually decreased and that of CT and US has increased over the periods. With regard to imaging modalities for definition, the proportion of angiography has decreased and that of CT has increased. From chronological changes in clinical pictures and imaging modalities, we suggested a decision tree of imaging modalities for detection and definition of renal cell carcinoma. (author)

    Previous epidemiological studies of overall alcohol intake and basal cell carcinoma (BCC) are inconsistent, with some evidence for differences by type of alcoholic beverage. While alcohol may enhance the carcinogenicity of ultraviolet (UV) radiation, this has not been evaluated in existing epidemiological studies. To evaluate alcohol intake in relation to early-onset BCC, and explore potential interactions with UV exposure. Basal cell carcinoma cases (n = 380) and controls with benign skin conditions (n = 390) under 40 years of age were identified through Yale Dermatopathology. Participants provided information on lifetime alcohol intake, including type of beverage, during an in-person interview. Self-reported data on indoor tanning and outdoor sunbathing were used to categorize UV exposure. We calculated odds ratios (OR) and 95% confidence intervals (CIs) using unconditional multivariate logistic regression in the full sample and in women only. There was no statistically significant association between lifetime alcohol intake and early-onset BCC overall [above median intake vs. no regular alcohol intake (OR 1·10, 95% CI 0·69-1·73)] or in women only (OR 1·21, 95% CI 0·73-2·01). Similarly, intake of red wine, white wine, beer or spirits and mixed drinks was not associated with early-onset BCC. In exploratory analyses, we saw limited evidence for an interaction (P(interaction) = 0·003), with highest risk for high alcohol and high UV exposures, especially in women, but subgroup risk estimates had wide and overlapping CIs. Overall, we did not observe any clear association between lifetime alcohol intake and early-onset BCC. © 2014 British Association of Dermatologists.

    Full Text Available BACKGROUND There are many studies reported in the literature with respect to the Ductal Carcinoma in Situ (DCIS progressing into Invasive Ductal Carcinoma (IDC of the breast. However, there is hardly any study on the coexistence of both and its clinical significance. The aim of the study is to analyse the clinical and pathological parameters of synchronous DCIS and IDC to predict the prognostic factors. MATERIALS AND METHODS 42 patients with a final pathological diagnosis of synchronous DCIS and IDC diagnosed in 2009-11 were included in the study. Statistical analysis was done using SPSS software utilising the appropriate analytical methods. RESULTS Majority of the patients in this study group presented with early breast cancer (64.3%. Forty eight percent were Her2 subtype (ER, PR negative and HER2/neu-positive and 31% were triple negative. Eighty one percent of the IDC associated histology was Not Otherwise Specified (NOS type. Grade 3 lesions were more common (57%. Recurrence of the disease occurred in 66% of patients during a mean duration of follow up of 3.6 years with predominance of visceral metastasis (51.5%. Recurrence was more common in node positive disease (59.5%, those with lymphovascular emboli (59.5% and perinodal spread (76% on histopathological examination. CONCLUSION Synchronous DCIS and IDC disease entity appears to have an aggressive nature compared to the course of IDC alone entity. Prognostic factors relating to IDC appears to correlate well with recurrence than that of the prognostic factors of DCIS component in such synchronous setting.

    Xeroderma pigmentosum is a rare autosomal-recessive disorder that appears in early childhood. Squamous cell carcinoma is not uncommon in patients with xeroderma pigmentosum and mostly involving the face, head, neck, and scalp. However, squamous cell carcinoma of the scalp may exhibit an aggressive course. Here, we present a huge squamous cell carcinoma of the scalp in a three-years-old child with xeroderma pigmentosum. In addition, we illustrate the challenges of a child with xeroderma pigmentosum who grows up in a sunny environment where the possibility of early onset of squamous cell carcinoma is extremely high in any suspected skin lesion. In xeroderma pigmentosum patients, squamous cell carcinoma of the scalp can present early and tends to be unusually aggressive. In sunny areas, proper education to the patient and their parents about ultra-violet light protection and early recognition of any suspicious lesion could be life-saving.

    Purpose/Objective: Interstitial fluid pressure (IFP) has been found to be elevated in cervical carcinomas. This study sought to evaluate IFP as a potential early measure of tumor response to radiation therapy. Identification of poor responders early in the course of treatment may allow the clinician to modify the treatment strategy early in the course of therapy. Materials and Methods: IFP was measured using the wick-in-needle technique in 42 patients undergoing definitive radiotherapy for carcinoma of the cervix. Measurements were taken before and after external beam radiation treatment (EBRT) in 25, after intracavitary treatment (ICT) in 7, and after both EBRT and ICT in 10 patients. An additional 10 patients had weekly measurements during radiotherapy. Tumor stage, size, hemoglobin, and clinical response were assessed and correlated with IFP readings. Results: All initial IFP readings were elevated. The extent of elevation did not correlate with outcome (p=0.76) or stage (p=0.6). Smaller tumors had a higher initial IFP (p=0.02). Tumor response correlated with change in IFP readings (p=0.01), tumor size (0.04), hemoglobin (p=0.01), and stage (0.04). On multivariate analysis, change in IFP remained an independent predictor of response. The IFP change from pretreatment to post-EBRT was - 13±3 in complete responders versus 4±11 and 18±10 in the partial and nonresponders respectively (p=0.01). In those with post-ICT readings, the change was -18±4 in complete responders versus 54±18 in the partial responders (p=0.01). In 10 patients undergoing weekly measurement, 8 complete responders had decreasing IFP measurements. An average fall of 51.6% was seen in five patients at < 1620cGy despite little or no change in tumor size, and by 2700cGy (average decrease 31%) in the remaining 3 complete responders. Nonresponders had either no change or an increase in IFP throughout EBRT. Conclusion: IFP is elevated in tumors of the uterine cervix. Decreasing IFP measurement

    Background: The lung is the most common site of distant metastases from hepatocellular carcinoma. Correct differentiation between metastatic hepatocellular carcinoma of the lung and primary lung cancer is sometimes difficult without biopsy. Purpose: To evaluate the usefulness of measuring the attenuations of pulmonary nodules on early-phase contrast-enhanced computed tomography (CT) for the differentiation of pulmonary metastases from hepatocellular carcinoma and primary lung cancer. Material and Methods: Thirteen patients with pulmonary metastases from hepatocellular carcinoma (nine men, four women; age 53.9±14.2 years, range 16-70 years) and 25 patients with primary lung cancer (14 men, 11 women; age 62.2±9.4 years, range 43-72 years) were retrospectively evaluated. Contrast-enhanced scans were obtained 35 s after commencing intravenous injection of contrast medium. Attenuation values and the size of the pulmonary nodules were measured on contrast-enhanced CT scans. CT and clinical features were analyzed with regard to age, sex, body surface area of the patients, the attenuation values and size of the nodules, and CT machines using univariate analysis (Fisher's exact test for binary data sets and the Mann-Whitney U test for continuous data sets). Multiple linear regression analysis was used to eliminate confounding factors. Results: The mean attenuation value of metastatic pulmonary nodules from hepatocellular carcinoma (75.7±24.9 HU) was higher than that of primary lung cancer nodules (45.8±14.4 HU) (P<0.01). Other variables such as age, sex, body surface area of the patients, CT device, and nodule size were not significant variables on multiple regression analysis. When a cut-off value of 75 HU was applied, the positive predictive value for diagnosing metastatic nodules from hepatocellular carcinoma was 100%. Conclusion: Pending confirmation in a large study, our findings suggest that there is a difference in contrast enhancement between pulmonary

    Full Text Available Background: Accurate clinical staging is important for patient counseling, treatment planning, prognostication, and rational design of clinical trials. In head and neck squamous cell carcinoma, discrepancy between clinical and pathological staging has been reported. Objective: To evaluate any disparity between clinical and pathological tumor-node-metastasis (TNM staging in oral cavity squamous cell carcinoma (OCSCC patients and any impact of the same on survival. Materials and Methods: Retrospective chart review from year 2007 to 2013, at a tertiary care center. Statistical Analysis: All survival analyses were performed using SPSS for Windows version 15 (Chicago, IL, USA. Disease-free survival curves were generated using Kaplan-Meier algorithm. Results: One hundred and twenty-seven patients with OCSCC were analyzed. Seventy-nine (62.2% were males and 48 (37.8% females with a mean age at presentation 43.6 years (29-79 years. The highest congruence between clinical and pathological T-staging seen for clinical stage T1 and T4 at 76.9% and 73.4% with pathological T-stage. Similarly, the highest congruence between clinical and pathological N-stage seen for clinical N0 and N3 at 86.4% and 91.7% with pathological N-stage. Of clinically early stage patients, 67.5% remained early stage, and 32.5% were upstaged to advanced stage following pathological analysis. Of the clinically advanced stage patients, 75% remained advanced, and 25% were pathologically downstaged. This staging discrepancy did not significantly alter the survival. Conclusion: Some disparity exists in clinical and pathological TNM staging of OCSCC, which could affect treatment planning and survival of patients. Hence, more unified and even system of staging for the disease is required for proper decision-making.

    1997-01-01

    Purpose: Treatment and disease-related factors were analyzed for their influence on the outcome of patients treated definitively with irradiation (RT) for early glottic carcinoma. Methods and Materials: One hundred two patients with stage T1 or T2 glottic carcinomas were treated definitively with RT from December 1983 through September 1993. Median follow-up time was 63 months. Factors analyzed for each patient included age, sex, stage, anterior commissure involvement, surgical alternative, histologic differentiation, field size, total dose, fraction size, and total treatment time. Survival analysis methods were employed to assess the effects of these factors on local control and complication rates. Results: The 5-year local control rates by stage were as follows: T1a, 92%; T1b, 80%; T2a, 94%; and T2b, 23%. By univariate analysis, factors found to have a significant impact on local control were stage, surgical alternative, fraction size, anterior commissure involvement, and overall treatment time. By multivariate analysis, stage, field size, and fraction size were the only significant factors that independently influenced local control. Conclusion: The inferior control rate for stage T2b lesions has implications for treatment. Our study supports the conclusion of reports in the literature showing that low fraction size negatively influences outcome in patients with early glottic cancer

    1995-01-01

    Purpose/Objective: The course will be divided into three major topics: (1) Review of radiobiological principles as they apply to the radiotherapeutic management of skin carcinomas; (2) review of radiotherapeutic techniques including beam qualities, beam collimation, tissue dose profiles, and the relative indications of external beam irradiation vs. brachytherapy; (3) comprehensive review of the tumor biology of skin malignancies, including malignant melanoma, and of the relative indications for radiotherapeutic and/or surgical management. (1) Review of critical data which have lead to currently applied principles of time-dose-volume concepts in the radiotherapeutic management of skin carcinomas. Emphasis will be placed on the relative importance of fraction size and overall treatment time on tumor control probability and acute and late normal tissue toxicity. (2) Considering that radiotherapy in the management of skin carcinomas is often used to minimize patient disfiguration and to preserve critical body functions (e.g. eye lids) the technical aspects of radiotherapy delivery are most critical. Careful evaluation of the extent of the lesions including evaluation of their depth of invasion will determine the quality of the radiation beams, orthovoltage and low energy electrons being the most useful. Beam harding for orthovoltage beams and secondary and tertiary (skin) collimation of appropriate electron beams are critical. For more extensive and deeply invasive lesions contour-shaping through customized bolus material is essential. Equally important is the familiarity with custom shielding of critical structures, such as eyes, ears, oral cavity and central nervous system structures. Brachytherapy applications in the treatment of skin carcinomas is limited but should be considered when implants with high dose uniformity can be constructed. (3) The discussion of clinical management will start with a discussion of tumor biological properties of the diverse malignant

    Forty nine patients with squamous cell carcinoma of oral tongue were reviewed retrospectively for the evaluation of clinical manifestation and for the comparison between therapeutic modalities. The gross shape of the tumor was infiltrative in 22, ulcerative in 12, and ulceroinfiltrative type in 10 patients. Direct extension of the tumor was most commonly to the floor of the mouth. The incidence of nodal metastasis generally increased with tumor stage. 55% of the patients showed neck nodal metastasis at the time of diagnosis. Ipsilateral subdigastric node were most commonly involved, followed by submandibular nodes. The 5-year survival rate of patients treated with surgery and radiotherapy was 58.7% in contrast to 21.6% in radiation alone group. Overall 5-year survival rate was 31%. In radiation alone group, half of the patients in stage I, II were locally controlled. But the local control in stage III, IV was much inferior to early lesions. Especially, of 4 patients combined with implantation technique, 3 were completely controlled. 5-year survival rate of these implanted patients was 50%, 49.4% of patients treated over 7,000 cGy survived 5 years. This was significant in contrast to 6.4% of the group treated below 7,000 cGy. The most common sites of failures were primary sites. In early lesions primary radiotherapy with implantation would be an appropriate treatment in cancer of oral tongue, operation reserved for radiation failure. Operation and adjuvant radiotherapy is recommended in cases of advanced disease

    Follicular thyroid carcinoma (FTC) is considered as a disease of the elderly with a higher incidence in females as compared to papillary thyroid carcinoma (PTC). Some studies have reported its occurrence at an early age, which may be attributed to early diagnosis because of the availability of advanced techniques. The prognosis of the disease is considered poor as compared to that of PTC. The conclusions drawn in this review are based on 663 cases in whom adequate data was available for meaningful analysis followed for a mean period of 9.2 years, median, 7.8 years; range, 1-32 years

    Computed tomographic (CT) findings of pancreatic ductal adenocarcinoma were studied with the combined method of early enhancement CT and high dose enhancement CT in 72 carcinomas. Common Findings were change in pancreatic contour, abnormal attenuation in a tumor and dilatation of the main pancreatic duct. The incidence of abnormal attenuation and dilatation of the main pancreatic duct and bile duct was constant regardless of tumor size. The finding of hypoattenuation at early enhancement CT was most useful for demonstrating a carcinoma. However, this finding was negative in ten cases, five of which showed inhomogenous hyperattenuation at high dose enhancement CT. The detection of change in pancreatic contour and dilatation of the main pancreatic duct was most frequent at high dose enhancement CT. The finding of change in pancreatic contour and/or abnormal attenuation in a tumor could be detected in 47 cases at plain CT, 66 at early enhancement CT and 65 at high dose enhancement CT. Since the four cases in which neither finding was detected by any CT method showed dilatated main pancreatic duct, there was no case without abnormal CT findings. This combined CT method will be a reliable diagnostic technique in the imaging of pancreatic carcinoma. (author)

    The objective of this study was to characterize the novel clinical and pathological features of mixed acinar-endocrine carcinoma of the pancreas. This was a retrospective review of medical records and surgical pathology specimens of patients with a diagnosis of mixed acinar-endocrine carcinoma of the pancreas at Cedars-Sinai Medical Center between 2005 and 2011. Additional immunohistochemistry was performed on the specimens of some patients. Five patients were identified. The median age at presentation was 74 years (range, 59-89 years), and all patients were male. The presenting symptoms were all related to tumor mass effects. The median size of the tumor was 10 cm (range, 3.9-16 cm). Preoperative clinical diagnosis aided by fine-needle aspiration biopsy was incorrect in all 5 cases. Most tumors (3/5) exhibited predominantly endocrine differentiation without hormonal production. Only 10% to 30% of cells were truly amphicrine, whereas most were differentiated into either endocrine or acinar phenotype. The clinical behavior ranged from moderate to aggressive with postoperative survival from 2.5 months to more than 3 years. Four patients received neoadjuvant or adjuvant chemotherapy with variable responses. Mixed acinar-endocrine carcinoma of the pancreas appears to be not uncommon in men, may harbor predominantly endocrine component, is often misdiagnosed by cytology, and exhibits variable clinical behavior. Mixed acinar-endocrine carcinoma of the pancreas should be considered in older patients with sizable pancreatic mass and may warrant aggressive surgical resection and chemotherapy.

    To investigate the role and significance of CD45RO in occurance and development in laryngeal squamous carcinoma, and to provide some valuable clues for searching new approaches to assess prognosis and theoretical basis for tumor biotherapy. The expression of CD45RO protein in 50 cases of laryngeal squamous carcinoma and 10 cases normal mucos was detected by immunohistochemical S-P method. The positive rate of CD45RO was 30% and 86% respectively in normal tissue and laryngeal squamous cell carcinoma tissue. The expresion of CD45RO was significantly and negatively associated with local metastatic of lymph nodes 0.713, P < 0.05) and tumor sites (r = -0.750, P < 0.05), but it have no notable difference with pathology differentiation, age, infiltrating depth and clinical stages in 50 cases of laryngeal squamous cell cancer. (1) The expresion of CD45RO in laryngeal squamous cell cancer is more than that in normal tissue. (2) It is possible that overexpresion of CD45RO in laryngeal squamous cell carcinoma cut local metastatic lymph nodes. (3) It is probable that overexpresion of CD45RO in laryngeal squamous cell cancer made for prognosis of patients. (4) Other than UICC-TNM stage, pathology differentiation, it provide valuable clues for searching new approaches to assess prognosis of laryngeal squamous cell carcinoma.

    A normal-sized ovarian papillary serous carcinoma is rare. We present the case of a 46-year-old woman with progressive abdominal fullness of one week's duration. The medical evaluation revealed abdominal carcinomatosis with normal-sized ovaries and an elevated serum CA-125 level of 147,365.8 U/ml. Cytoreductive surgery (hysterectomy, bilateral salpingo-oophorectomy, omentectomy, lymphadenectomy, infracolic omentectomy, peritoneal biopsy, washing cytology, and appendectomy) was performed. The histologic examination revealed an ovarian serous papillary carcinoma. Adjuvant chemotherapy was administered. The serum CA-125 level decreased after completion of treatment. Normal-sized ovarian serous surface papillary carcinomas should be kept in mind as an origin of disease in patients who have peritoneal carcinomatosis, which sometimes is a diagnostic dilemma of the disease source. We report this case to emphasize the clinical symptoms and importance of the early and accurate diagnosis of a normal-sized ovarian papillary serous carcinoma.

  6. Are metastases from metastases clinical relevant? Computer modelling of cancer spread in a case of hepatocellular carcinoma.

    Directory of Open Access Journals (Sweden)

    Anja Bethge

    Full Text Available BACKGROUND: Metastasis formation remains an enigmatic process and one of the main questions recently asked is whether metastases are able to generate further metastases. Different models have been proposed to answer this question; however, their clinical significance remains unclear. Therefore a computer model was developed that permits comparison of the different models quantitatively with clinical data and that additionally predicts the outcome of treatment interventions. METHODS: The computer model is based on discrete events simulation approach. On the basis of a case from an untreated patient with hepatocellular carcinoma and its multiple metastases in the liver, it was evaluated whether metastases are able to metastasise and in particular if late disseminated tumour cells are still capable to form metastases. Additionally, the resection of the primary tumour was simulated. The simulation results were compared with clinical data. RESULTS: The simulation results reveal that the number of metastases varies significantly between scenarios where metastases metastasise and scenarios where they do not. In contrast, the total tumour mass is nearly unaffected by the two different modes of metastasis formation. Furthermore, the results provide evidence that metastasis formation is an early event and that late disseminated tumour cells are still capable of forming metastases. Simulations also allow estimating how the resection of the primary tumour delays the patient's death. CONCLUSION: The simulation results indicate that for this particular case of a hepatocellular carcinoma late metastases, i.e., metastases from metastases, are irrelevant in terms of total tumour mass. Hence metastases seeded from metastases are clinically irrelevant in our model system. Only the first metastases seeded from the primary tumour contribute significantly to the tumour burden and thus cause the patient's death.

    2015-01-01

    Fibrolamellar hepatocellular carcinoma is a rare primary malignant liver tumor, significantly different from generic hepatocellular carcinoma with distinct demographics, risk factors, imaging features, histopathology and prognosis. Unlike conventional hepatocellular carcinoma, it presents in young individuals with no preexisting hepatitis or cirrhosis and does not cause elevation of serum alpha feto proteins in most cases. This paper presents a case report of this rare tumor in a young female with an unusual clinical manifestation of obstructive jaundice (which has not been reported so far) along with a review of its imaging and pathological features, with treatment options. Fibrolamellar HCC is a rare variant of classic HCC with different epidemiology, risk factors, clinical manifestations, radiological, pathological and prognostic features. Therefore, it is important to be familiar with the entity for its early diagnosis and management

    In our center limited centro pelvic invasive carcinomas of the uterine cervix (less than 4 cm) are treated with brachytherapy and surgery. With these therapeutic modalities no residual carcinoma was observed for 80% of the patients. The purpose of this study was to evaluate our results with this treatment, and to evaluate the prognostic value of the pathological status of the cervix. From 1976 to 1987 we have treated 115 patients with these modalities. Staging system used was the FIGO classification modified for Stage II (divided in early Stage II and late Stage II). Patients were Stage IB (70 cases) and early Stage II (45 cases); 60 Gy were delivered with utero vaginal brachytherapy before any treatment. Six weeks later a radical hysterectomy with pelvic lymphadenectomy was performed. Twenty-one patients with positive nodes received a pelvic radiotherapy (45 to 55 Gy). Local control rate was 97% (100% for Stage IB and 93% for early Stage II). Uncorrected 10-year actuarial survival rate was 96% for Stage IB and 80% for early Stage II patients. No treatment failure was observed for Stage IB patients. Ninety-two patients (80%) had no residual carcinoma in the cervix (group 1) and 23 patients (20%) had a residual tumor (group 2). The sterilization rate of the cervix was 87% for Stage IB tumors versus 69% for early Stage II, and was 82% for N- patients versus 68% for N+ patients. Ten year actuarial survival rate was 92% for group 1 and 78% for group 2 (p = 0, 1). Grade 3 complications rate was 6%. We conclude that brachytherapy + surgery is a safe treatment for limited centro pelvic carcinomas of the uterine cervix (especially Stage IB) and that pathological status of the cervix after brachytherapy is not a prognostic factor

    To investigate the clinical usefulness of a follow-up examination using serum squamous cell carcinoma antigen (SCC) for the early detection of recurrence in patients treated for cervical squamous cell carcinoma. 20 patients who were treated for recurrent cervical squamous cell carcinoma between 1997 and 1998, who had experienced a complete remission after radiotherapy and who underwent an SCC test around the time when recurrence was detected, were included in this study. The levels of SCC were measured from the serum of the patients by immunoassay and values less than 2 ng/mL were regarded as normal. The sensitivity of the SCC test for use in the detection of recurrence, the association between the SCC values and the recurrence patterns and the tumor size and stage, and the temporal relation between the SCC increment and recurrence detection were evaluated. The SCC values were above normal in 17 out of 20 patients, so the sensitivity of the SCC test for the detection of recurrence was 85%, and the mean and median of the SCC values were 15.2 and 9.5 ng/mL, respectively. No differences were observed in the SCC values according to the recurrence sites. For 11 patients, the SCC values were measured over a pero id of 6 months before recurrence was detected, and the mean and median values were 13.6 and 3.6 ng/mL, respectively. The SCC values of 7 patients were higher than the normal range, and the SCC values of the other 4 patients were normal but 3 among them were above 1.5 ng/mL. At the time of diagnosis, the SCC valuess were measured for 16 of the 20 recurrent patients, and the SCC values of the patients with a bulky tumor (≥ 4 cm) or who were in stage IIb or III were higher than those of the patients with a non-bulky tumor or who were in stage Ib or IIa. The SCC test is thought to be useful for the early detection of recurrence during the follow up period in patients treated for cervical squamous cell carcinoma. When an effective salvage treatment is developed in

    Improving technologies for the detection and purification of bone marrow (BM) micrometastatic cells in breast cancer patients should lead to earlier prognosis of the risk of relapse and should make it possible to design more appropriate therapies. The technique used has to overcome the challenges resulting from the small number of target cells (one per million hematopoietic cells) and the heterogeneous expression of micrometastatic cell markers. In the present study, we have assessed the clinical relevance of current methods aimed at detecting rare disseminated carcinoma cells. BM aspirates from 32 carcinoma patients were screened for the presence of micrometastatic cells positive for epithelial cell adhesion molecule and positive for cytokeratins, using optimized immunodetection methods. A comparison with data obtained for 46 control BM aspirates and a correlation with the clinical status of patients were performed. We developed a sensitive and efficient immunomagnetic protocol for the enrichment of BM micrometastases. This method was used to divide 32 breast carcinoma patients into three categories according to their epithelial cell adhesion molecule status. These categories were highly correlated with the recently revised American Joint Committee on Cancer staging system for breast cancer, demonstrating the clinical relevance of this simple and reliable immunomagnetic technique. We also evaluated immunocytochemical detection of cytokeratin-positive cells and cytomorphological parameters. Immunocytochemistry-based methods for the detection of BM micrometastases did not provide any information about the clinical status of patients, but helped to refine the immunomagnetic data by confirming the presence of micrometastases in some cases. We also tested a new density gradient centrifugation system, able to enrich the tumor fraction of BM specimens by twofold to threefold as compared with standard Ficoll methods. These improved methods for the detection of

Radiotherapy is the primary treatment modality. The role of systemic therapy has become more prominent. Based on multiple phase III studies and meta-analyses, concurrent cisplatin-based chemoradiotherapy is the current standard of care for locally advanced disease (American Joint Committee on Cancer manual [7th edition] stages II–IVb. The reported failure-free survival rates from phase II trials are encouraging for induction + concurrent chemoradiotherapy. Data from ongoing phase III trials comparing induction + concurrent chemoradiotherapy with concurrent chemoradiotherapy will validate the results of these phase II studies. Intensity-modulated radiotherapy techniques are recommended if the resources are available. Locoregional control exceeding 90% and reduced xerostomia-related toxicities can now be achieved using intensity-modulated radiotherapy, although distant control remains the most pressing research problem. The promising results of targeted therapy and Epstein–Barr virus-specific immunotherapy from early clinical trials should be validated in phase III clinical trials. New technology, more effective and less toxic chemotherapy regimens, and targeted therapy offer new opportunities for treating nasopharyngeal carcinoma.Keywords: nasopharyngeal carcinoma, intensity-modulated radiotherapy, chemoradiotherapy, molecular targeted agents, immunotherapy, prognostic markers

    Hepatocellular carcinoma is the most common primary tumor of the liver. Spreading outside the liver usually takes place in advanced stages of the disease, and bone is the third most common site of metastases. We present a case of hepatocellular carcinoma in which the first clinical manifestation was a single metastasis to the carpal bones. The interest of this case lies in the way this hepatocellular carcinoma manifested as well as in the unusual site of the metastasis. Copyright © 2012 SERAM. Published by Elsevier Espana.

    The purpose of this work was to study the differences of cyclooxygenase (COX-2) expression between Korean and Caucasian patients with early-onset breast carcinoma by immunohistochemistry. The test were analyzed to find a correlation between COX-2 and other biomarkers including HER-2/neu amplification, because we previously reported that a significant difference had been found in the expression of HER-2/neu between the two races. Furthermore, we investigated prognostic significance of COX-2 in Korean patients. Sixty Korean women who were diagnosed breast carcinoma at 45 years old or younger and 60 Caucasian women with breast carcinoma were selected for this study. The median age of both groups was 37 years and tumor sizes were distributed evenly between the two group. Paraffin embedded blocks of primary tumor were processed for immunohistochemical staining of COX-2. The COX-2 expression was evaluated according to the percentage of positive cells and the intensity of staining. And the results were compared with the data of the previous studies to find correlation between COX-2 and other parameters and survival data. Proportion of the COX-2 expression in total patients was 27.6%. The percentage of tumors that stained positive for COX-2 in Korean and Caucasian women with early-onset breast carcinoma were 37.9% and 20.8%, respectively. The difference was statistically not significant (ρ 0.090). Expression of COX-2 was not associated with several clinicopathologic parameters including HER-2/neu overexpression, but negative estrogen receptor status was correlated with significance (ρ = 0.046). The 5 year disease free survival rate for patients with COX-2 expression was 67.9%, compared to 81.9% of the COX-2 negative patients and the result was statistically not significant. A significant difference was not found in the expression of COX-2 between the two groups of patients with early-onset breast carcinoma. And correlation between COX-2 and other parameters was not

    Surface-enhanced Raman spectroscopy (SERS) was employed to detect deoxyribose nucleic acid (DNA) variations associated with the development of nasopharyngeal carcinoma (NPC). Significant SERS spectral differences between the DNA extracted from early NPC, advanced NPC, and normal nasopharyngeal tissue specimens were observed at 678, 729, 788, 1337, 1421, 1506, and 1573 cm-1, which reflects the genetic variations in NPC. Principal component analysis combined with discriminant function analysis for early NPC discrimination yielded a diagnostic accuracy of 86.8%, 92.3%, and 87.9% for early NPC, advanced NPC, and normal nasopharyngeal tissue DNA, respectively. In this exploratory study, we demonstrated the potential of SERS for early detection of NPC based on the DNA molecular study of biopsy tissues.

    Detection of early hepatocellular carcinoma (HCC) is responsible for increasing survival rates in up to 40%. One-class classifiers can be used for modeling early HCC in multidetector computed tomography (MDCT), but demand the specific knowledge pertaining to the set of features that best describes the target class. Although the literature outlines several features for characterizing liver lesions, it is unclear which is most relevant for describing early HCC. In this paper, we introduce an unconstrained GA feature selection algorithm based on a multi-objective Mahalanobis fitness function to improve the classification performance for early HCC. We compared our approach to a constrained Mahalanobis function and two other unconstrained functions using Welch's t-test and Gaussian Data Descriptors. The performance of each fitness function was evaluated by cross-validating a one-class SVM. The results show that the proposed multi-objective Mahalanobis fitness function is capable of significantly reducing data dimensionality (96.4%) and improving one-class classification of early HCC (0.84 AUC). Furthermore, the results provide strong evidence that intensity features extracted at the arterial to portal and arterial to equilibrium phases are important for classifying early HCC.

    To determine the underlying mechanism for the differential expression, the extent of promoter methylation in tumor necrosis factor-related apoptosis-inducing ligand (TRAIL)-related genes acting downstream of TRAIL was examined in early and advanced gastric carcinomas. The extent of promoter methylation in the DR4, DR5, DcR1, DcR2, and CASP8 genes was quantified using bisulfite modification and methylation-specific polymerase chain reaction. The promoters for DcR1, DcR2, and CASP8 were largely unmethylated in early gastric carcinoma, advanced gastric carcinoma, and controls, with no significant difference among them. Protein levels of DR4, DcR1, and DcR2 as revealed by immunohistochemistry correlated with the extent of the respective promoter methylation (P < 0.05 in all cases). Hypomethylation, rather than hypermethylation, of the DR4 promoter was noted in invasive gastric malignancies, with statistical significance (P = 0.003). The promoter methylation status of TRAIL receptors in gastric carcinoma may have clinical implications for improving therapeutic strategies in patients with gastric carcinoma.

    Nasopharyngeal carcinoma (NPC) is a common cancer in Malaysia. The clinical presentation in Sarawak has not been well documented. A retrospective review of 213 selected NPC cases was undertaken on the clinical records in Sarawak General Hospital, Sarawak, from June 1999 to June 2003. There were 116 patients in Kuching and 97 in Serian. There were twice as many males as females. The youngest patient was 16 and the oldest 88 years old with a mean age of 51 years. The four most common symptoms in order of frequencies were cervical lymphadenopathy, epistaxis, hearing loss and diplopia. 80.8% of the patients presented with cervical lymphadenopathy and about 85% of the patients presented in the advanced stages. Very small percentages of the patients were found to have single presenting symptoms of epistaxis (2.4%) and hearing loss (0.5%).

    Purpose: We recently reported on the identification of the Fas-associated death domain (FADD) as a possible driver of the chromosome 11q13 amplicon and the association between increased FADD expression and disease-specific survival in advanced-stage laryngeal carcinoma. The aim of this study was to examine whether expression of FADD and its Ser194-phosphorylated isoform (pFADD) predicts local control in patients with early-stage glottic carcinoma primarily treated with radiotherapy only. Methods and Materials: Immunohistochemical staining for FADD and pFADD was performed on pretreatment biopsy specimens of 92 patients with T1–T2 glottic squamous cell carcinoma primarily treated with radiotherapy between 1996 and 2005. Cox regression analysis was used to correlate expression levels with local control. Results: High levels of pFADD were associated with significantly better local control (hazard ratio, 2.40; 95% confidence interval, 1.04–5.55; p = 0.040). FADD overexpression showed a trend toward better local control (hazard ratio, 3.656; 95% confidence interval, 0.853–15.663; p = 0.081). Multivariate Cox regression analysis showed that high pFADD expression was the best predictor of local control after radiotherapy. Conclusions: This study showed that expression of phosphorylated FADD is a new prognostic biomarker for better local control after radiotherapy in patients with early-stage glottic carcinomas.

    We report a case of Wegener's granulomatosis clinically mistaken for carcinoma in a 21-year-old girl presenting with an ulcerated mass of the nasopharynx associated with enlarged laterocervical nodes. The lesion was clinically suspected as malignant on the basis of clinical and radiological findings (namely, computed tomography scan and positron emission tomography). However, multiple biopsies were not conclusive for malignancy showing histological change suggestive of Wegener's granulomatosis. A serum determination of cANCA supported the diagnosis of Wegener's granulomatosis. Clinical findings and image studies suggested an erroneous diagnosis of malignancy whereas a definitive diagnosis of Wegener's granulomatosis was achieved only after repeated biopsies thus leading to a correct therapeutic approach. The Wegener granulomatosis must be added to the list of the differential diagnoses of the masses of the nasopharynx associated with or without enlarged laterocervical nodes. PMID:24106630

    To investigate hypoxia-induced factor-1 alpha expression in distinct oral squamous cell carcinoma subtypes and topographies and correlate with clinicopathological data. Hypoxia-induced factor-1 alpha expression was assessed by immunohistochemistry in 93 cases of OSCC. Clinical and histopathological data were reviewed from medical records. Hypoxia-induced factor-1 alpha status was distinct according to tumor location, subtype and topography affect. In superficial oral squamous cell carcinomas, most tumor cells overexpressed hypoxia-induced factor-1 alpha, whereas hypoxia-induced factor-1 alpha was restricted to the intratumoral region in conventional squamous cell carcinomas. All basaloid squamous cell carcinomas exhibited downregulation of hypoxia-induced factor-1 alpha. Interestingly, metastatic lymph nodes (91.7%, p = 0.001) and the intratumoral regions of corresponding primary tumors (58.3%, p = 0.142) showed hypoxia-induced factor-1 alpha-positive tumor cells. Overall survival was poor in patients with metastatic lymph nodes. Hypoxia-induced factor-1 alpha has distinct expression patterns in different oral squamous cell carcinoma subtypes and topographies, suggesting that low oxygen tension promotes the growth pattern of superficial and conventional squamous cell carcinoma, but not basaloid squamous cell carcinoma. Indeed, a hypoxic environment may facilitate regional metastasis, making it a useful diagnostic and prognostic marker in primary tumors.

    Mortality is high in patients with esophageal carcinoma as tumors are rarely detected before the disease has progressed to an advanced stage. Here, we sought to isolate cell-free DNA released into the plasma of patients with esophageal carcinoma, to analyze copy number variations of marker genes in the search for early detection of tumor progression. Plasma of 41 patients with esophageal carcinoma was prospectively collected before tumor resection and chemotherapy. Our dataset resulted heterogeneous for clinical data, resembling the characteristics of the tumor. DNA from the plasma was extracted to analyze copy number variations of the erbB2 gene using real-time PCR assays. The real-time PCR assays for erbB2 gene showed significant (P = 0.001) copy number variations in the plasma of patients with esophageal carcinoma, as compared to healthy controls with high sensitivity (80%) and specificity (95%). These variations in erbB2 were negatively correlated to the progression free survival of these patients (P = 0.03), and revealed a further risk category stratification of patients with low VEGF expression levels. The copy number variation of erbB2 gene from plasma can be used as prognostic marker for early detection of patients at risk of worse clinical outcome in esophageal cancer

    State-of-the-art surgical staging and adjuvant chemotherapy in early-stage ovarian carcinoma have an impact on patient's outcome, but compliance to guidelines and consensus recommendations is still poor. This article reports on our results before and after introduction of a quality assurance and management program in our clinic in 2001. Patients with ovarian carcinoma limited to the pelvis who underwent primary surgery in our hospital from 1997 to October 2007 were eligible for this study. Univariate and multivariate logistic regression analyses were performed to evaluate the impact of compliance with our management program and physician's experience in ovarian carcinoma surgery on achieving both standards of surgery and chemotherapy. In a total of 117 women, a significant impact on adherence to guideline-defined comprehensive surgical staging was found for poor Eastern Cooperative Oncology Group performance status (odds ratio [OR], 22.16; confidence interval [CI] 3.2-152.0; P = 0.002) and year of surgery before 2001 (OR, 47.60; CI, 9.20-245.22; P grading less than G3 (OR, 4.14; CI, 1.20-14.22; P = 0.02) was a statistically significant predictor for receiving standard adjuvant chemotherapy. Survival analyses showed a trend toward improved survival for patients having received guideline-adopted therapy, but event numbers were too low for adequate analyses. The introduction of a quality assurance program for treatment of ovarian carcinoma represents a major improvement of patient care. It led to a higher compliance with consensus recommendations and showed already a trend toward improved outcome. Further outcome research should focus on methods for implementation of guidelines in daily practice in institutions caring for patients with ovarian carcinoma.

    Carcinoma gallbladder (CaGb) is a rare disease. The aetiology of CaGb is yet not known. However the risk of CaGb is increased in anomalous pancreaticobiliary duct junction (APBDJ), gall stones, xanthogranulomatus cholecystitis, calcified or porcelain gallbladder, cholelithiasis with typhoid carriers, gallbladder adenoma, red meat consumption and tobacco uses. There are protective effects of vegetables on CaGb. Most of the cases present with advanced disease. In early carcinoma of a gallbladder sign and symptoms mimic benign disease. The diagnosis is established by ultrasonography, computerized tomography and guided fine needle aspiration cytology (FNAC). Biochemical tests are of very little value in making a diagnosis. The treatment depends on the clinical stage at presentation. Surgery offers the best chance of cure. In stage T1a, laparoscopic or open cholecystectomy alone is curative, and in T1b, cholecystectomy with hepatoduodenal lymph node dissection without combined resection of an adjacent organ is required. Segment S4a+5 hepatectomy combined with extrahepatic bile duct resection (BDR) and D2 lymph node dissection is a highly recommended operation for the treatment of T2 and T3 CaGb. The dye injection method is useful in determining the appropriate extent of hepatic resection for advanced CaGb. Resurgery is required only in those cases where tumour has invaded the serosa and/ or adjacent structures when diagnosed postoperatively. Biliary bypass is required for palliation. Prognosis depends on early diagnosis and appropriate surgical excision.

    In mucoepidermoid carcinoma (MEC), the most common salivary gland carcinoma, there is a lack of novel prognostic markers, but post-operative early recurrence strongly affects the clinical course and a poor outcome. It is critical to predict which MEC patients are prone to develop recurrence/metastases. Mucins play pivotal roles in influencing cancer biology, thus affecting cell differentiation, adhesion, carcinoma invasion, aggressiveness and/or metastatic potential. Our aim is to elucidate the significance of expression profiles for mucins, particularly MUC4 and MUC6, and their correlations with various clinicopathological features and recurrence in salivary gland MECs. We performed immunohistochemical analyses on patients with surgically resected primary MEC using antibodies against mucin core proteins MUC4/8G7 and MUC6/CLH5 in 73 paraffin-embedded samples. Recurrence was noted in 15 of 73 (20.5%) patients. MUC4 or MUC6 expression was considered to be negative when <30% or 0% of the MEC cells showed positive staining, respectively. MUC4- and/or MUC6-negative expression respectively and variably showed a significant relationship to pathological tumor high-grade, the presence of lymphovascular invasion, lymph node metastasis and/or tumor-related death. In addition, MUC4 showed significantly negative co-expression with MUC6. Kaplan-Meier analyses revealed that not only single MUC4/6-negative expression but also the combination of both predicted significantly shorter disease-free and disease-specific survivals in MECs, especially within the first two years postoperatively. Therefore, each mucin plays a pivotal role in the pathogenesis of MEC progression. The detection of MUC4 and/or MUC6 might be a powerful parameter in the clinical management of MECs in the early postsurgical phase.

    Nasopharynx carcinomas (NPC) are a very special head and neck cancer, in term of epidemiology, clinic and pathology. Endemic disease in South East Asia, undifferentiated nasopharynx carcinoma are very frequent CT scan and NMR allow a better knowledge of the modalities of the clinical presentation. Prognostic factors include local and regional extension. NPC is a well known radiosensitive disease with a dose-response curve well established. Modern imaging modalities and modification of the ballistic explain the amelioration of the local control and the diminution of therapeutic sequelae. Brachytherapy is an interesting modalities for the boost and the treatment of recurrent disease. The exact place of 3 D CRT and IMRT is not yet known as modifications of fractionation. Local control for T1 T2 tumor is excellent but is related to clinical extension (cranial and neurologic involvement) and nodal extension (supra clavicular N3) and show the interest of combined chemo-radiotherapy protocols.

Methods A total of 178 patients with early-stage HCC who were initially treated with TACE and showed a CR based on the modified Response Evaluation Criteria in Solid Tumors (mRECIST criteria on one month follow-up computed tomography (CT were analyzed. Among them, 90 patients underwent scheduled repetition of TACE in the absence of viable tumor on CT. Results During a median follow-up period of 4.6 years (range: 0.4-8.8 years, mortality was observed in 71 patients (39.9%. The overall recurrence-free and local recurrence-free survival rates at 1 year were 44.4% and 56.2%. In the multivariable model, scheduled repetition of TACE was an independent factor associated with survival (hazard ratio [95% confidence interval]: 0.56 [0.34-0.93], P=0.025. When stratified using Barcelona clinic liver cancer (BCLC stage, scheduled repetition of TACE was associated with a favorable survival rate in BCLC stage A patients, but not in BCLC 0 patients. Conclusions Scheduled repetition of TACE was associated with better survival for early-stage HCC patients showing a CR after initial TACE, especially in BCLC stage A patients.

    Full Text Available BACKGROUND: The emergence of dengue throughout the tropical world is affecting an increasing proportion of adult cases. The clinical features of dengue in different age groups have not been well examined, especially in the context of early clinical diagnosis. METHODOLOGY/PRINCIPAL FINDINGS: We structured a prospective study of adults (≥ 18 years of age presenting with acute febrile illness within 72 hours from illness onset upon informed consent. Patients were followed up over a 3-4 week period to determine the clinical outcome. A total of 2,129 adults were enrolled in the study, of which 250 (11.7% had dengue. Differences in the rates of dengue-associated symptoms resulted in high sensitivities when the WHO 1997 or 2009 classification schemes for probable dengue fever were applied to the cohort. However, when the cases were stratified into age groups, fewer older adults reported symptoms such as myalgia, arthralgia, retro-orbital pain and mucosal bleeding, resulting in reduced sensitivity of the WHO classification schemes. On the other hand, the risks of severe dengue and hospitalization were not diminished in older adults, indicating that this group of patients can benefit from early diagnosis, especially when an antiviral drug becomes available. Our data also suggests that older adults who present with fever and leukopenia should be tested for dengue, even in the absence of other symptoms. CONCLUSION: Early clinical diagnosis based on previously defined symptoms that are associated with dengue, even when used in the schematics of both the WHO 1997 and 2009 classifications, is difficult in older adults.

    Objective: To evaluate the application of early 18 F-FDG PET-CT imaging after radiofrequency ablation (RFA) of hepatic malignancies. Methods: Fifteen patients with liver tumors (five hepatocellular carcinoma, ten colorectal cancer liver metastasis) underwent RFA as part of clinical management. The lesions were all hypermetabolic on PET-CT performed within 2 weeks prior to RFA. All subjects underwent 18 F-FDG PET-CT (early PET-CT) within 24 hours after RFA. Total photopenia, focal uptake, and rim-shaped uptake were regarded as complete ablation, residual tumor, and inflammation, respectively. Follow-up PET-CT scans were performed as the reference standard. Results: Twelve patients showed total photopenia at the ablation site on the early PET-CT scan, and in all of these patients, total photopenia at the ablation sites was seen on the follow-up PET-CT scans. Two patients had focal uptake at the ablation sites on the early PET-CT scan, and both of these foci increased in size and intensity, which were compatible with residual tumors at the time of ablation. Only one patient had rim-shaped uptake on the early PET-CT scan. The rim-shaped uptake disappeared on PET-CT performed 3 months later, which indicated the nature of inflammation. Conclusions: There is infrequent inflammatory uptake at the RFA site of liver tumors on 18 F-FDG PET-CT if scanning is performed within 24 hours after ablation. Thus, early PET- CT has the potential to evaluate the efficacy of an RFA procedure by indicating tumor-free as total photopenia and residual tumors as focal uptake. (authors)

    Fifty-eight patients with hypopharyngeal carcinoma, who were treated at our hospital (UOEH) from 1990 to 1999, were retrospectively analyzed regarding the treatment modalities and survival. Following induction chemotherapy (carboplatin (CBDCA)+5-fluorouracil (5-FU)), 36 operable cases underwent surgery (with or without a total-laryngectomy) and/or radiation therapy and 22 inoperable cases received 2 courses of chemotherapy followed by radiation therapy. The overall 5-year survival rate was 35.3% for all patients, 70% for stage I (n=2) and stage II (n=8), 25% for stage III (n=12), and 28.3% for stage IV (n=36). In 10 patients whose larynx was preserved because of a successful response to the induction chemotherapy, 8 cases survived more than 3 years without recurrence, and only one case died due to local failure. A more effective induction treatment such as a combination of chemotherapy and radiation were thought to make laryngeal preservation possible in patients with early stage disease. Of 26 patients who underwent surgery including a total laryngectomy, 11 cases had postoperative radiation therapy (30 to 70 Gy) because their surgical margin was not sufficient. The 5-year survival rate for the radiation group was 63.3%, while the rate for the non-radiation group was 31.3%. These results indicated that postoperative radiation therapy should therefore be performed in all patients with hypopharyngeal carcinoma even after undergoing successful surgery. (author)

    To assess the clinical outcomes of fertility-sparing treatments in young patients with epithelial ovarian carcinoma (EOC). A retrospective study of young EOC inpatients (≤40 years old) was performed during January 1994 and December 2010 in eight institutions. Data were analyzed from 94 patients treated with fertility-sparing surgery with a median follow-up time of 58.7 months. As histologic grade increased, overall survival (OS) and disease-free survival (DFS) of patients receiving fertility-sparing surgery declined. Neither staging surgery nor laparoscopy of early stage EOC with conservative surgery had a significant effect on OS or DFS. Normal menstruation recommenced after chemotherapy in 89% of the fertility-sparing group. Seventeen pregnancies among twelve patients were achieved by the end of the follow-ups. Fertility-sparing treatment for patients with EOC Stage I Grade 1 could be cautiously considered for young patients. The surgical procedure and surgical route might not significantly influence the prognosis. Standard chemotherapy is not likely to have an evident impact on ovarian function or fertility in young patients.

    The diagnostic role of cyclooxygenase-2 (COX-2) expression in laryngeal atypical hyperplasia, vocal fold nodule, and laryngeal squamous cell carcinoma was examined. Specimens obtained from patients diagnosed with vocal fold nodule (n = 35), atypical hyperplasia (n = 35), laryngeal squamous cell carcinoma (n = 35), and clinical parameters were evaluated retrospectively. Although no staining was observed in patients with vocal fold nodules, staining was noted in laryngeal atypical hyperplasia and squamous cell carcinoma. The percentage of COX-2 staining was the highest in the carcinoma group. It was determined that COX-2 staining was significantly associated with laryngeal squamous cell carcinoma. It should be noted that overexpression of COX-2, a potentially important factor in the evolution of carcinogenesis in precancerous lesions, might be an indicator of the development of carcinoma.

    Full Text Available The most common skin malignant tumor of the epidermoid origin are basal cell (BCC and squamous cell (SCC carcinoma. They occur at the photoexposed parts of the body in 90% of cases and are directly associated with skin damage caused by long term exposure to UV rays, usually in older persons and light skin. Almost 65,000 people die annually in the world from their consequences. The most important link in preventing the occurrence of these tumors is prevention, but their early identification allows adequate surgical treatment with sparing surrounding tissue. The main objective of this paper is to examine the histopathological and clinical-morphological characteristics of BCC and SCC of the skin of the head. The analysis included 439 cancer (297 (67.7% BCC, 126 (28.7% SCK and 16 (3.6% BCK + SCK, among which over 60% were diagnosed in men, usually in the seventh and eighth decade of life, with the highest incidence of BCC on the nose or on the skin of the upper half of the face and SCK on the lips or the skin of the lower half of face. All skin cancers of the head were more common on the right side. Clinical and morphological, most of the BCC were manifested by ulcerative form of average size 1.2cm and mixed histological type, and SCK by vegetative form of average size 1.55cm and histological grade I. The highest number of BCC and SCC was completly removed, in contrast to the combination of these two tumors among them in most cases the subsequent surgical intervention was necessary.

    Objective: To determine the accuracy of SLN biopsy for the assessment of auxiliary status, and prognostic markers leading to lymphatic metastasis in patients with early (T1) breast cancer. Design: Cross-sectional study. Place and Duration of Study: Department of Surgery, Teaching and Research Hospital. Between January 2000 and August 2004. Patients and Methods: SLN mapping by blue dye method was performed on 39 patients with T1 breast carcinoma. SLNs, level 1 and 2 auxiliary nodes were dissected and excised. The size, pathologic features of the primary tumor, SLNs and other auxiliary nodes, and hormone receptors were evaluated by histopathologic examination. The rate of SLNs and non SLNs involvement, and demographic, clinical and pathologic risk factors leading to nodal metastasis were established. The diagnostic accuracy of SLN for auxiliary status was calculated. Results: SLNs were identified in 37 (95%) patients. The axilla had metastasis in 11 (28%) patients. Malignant cells involved SLNs in 8 patients. Non-SLNs had metastasis in 3 patients without SLN involvement. The sensitivity, specificity and accuracy of SLN biopsy for predicting auxiliary status was calculated as 73%, 100% and 92% respectively. Four of 5 patients T1c tumors (p=0.14) and lymphovascular invasion (p=0.0004). Conclusion: SLN biopsy with high diagnostic accuracy may prevent unnecessary disection of the axilla in the majority of patients with early (T1) breast carcinoma. Some risk factors as pre-menopausal status, absence of hormone receptors, and presence of lymphovascular invasion must be taken into account as important determinant of non-SLNs metastasis. (author)

However, aberrant Hh signaling activation has been implicated in the development and promotion of certain types of cancer, including basal cell carcinoma (BCC, medulloblastoma, and gastrointestinal cancers. In 2015, the US Food and Drug Administration (FDA approved sonidegib, a smoothened (SMO antagonist, for treatment of advanced BCC (aBCC after a successful Phase II clinical trial. Sonidegib, also named Odomzo, is the second Hh signaling inhibitor approved by the FDA to treat BCCs following approval of the first SMO antagonist vismodegib in 2012. What are the major features of sonidegib (mechanism of action; metabolic profiles, clinical efficacy, safety, and tolerability profiles? Will the sonidegib experience help other clinical trials using Hh signaling inhibitors in the future? In this review, we will summarize current understanding of BCCs and Hh signaling. We will focus on sonidegib and its use in the clinic, and we will discuss ways to improve its clinical application in cancer therapeutics.

    From January 1985 to December 1994, 23 early stage carcinomas of the esophagus were treated by photodynamic therapy in 21 patients. The stage of the tumors was assessed by esophagoscopy with multiple biopsies, CT scan and, from June 1991, also by endoscopic ultrasonography: 7 lesions were classified as carcinoma in situ (Tis) and 16 as invasive (T1). The photosensitizers used for PDT were hematoporphyrin derivative 3 mg/kg in 4 patients and dihematoporphyrin ether 2 mg/kg in 17. Light irradiation was performed using an Argon-dye laser system at a wavelength of 630 nm with an average energy of 50 J/cm2 and 70 J/cm2 for the treatment of Tis and T1, respectively. A complete response was achieved in 17/23 (74%) tumors, 15/21 (71%) patients. In the follow-up period from 6 to 78 months (median 36 months) 3 recurrences occurred 6, 12, and 14 months after PDT, respectively. Seven patients died due to concomitant diseases, not related to tumor progression. The actuarial survival rate was 95%, 75% and 37% at 1, 3, and 5 years, respectively. Complications included 1 case of sunburn and 2 cases of esophageal stenosis at the treatment site, that gradually responded to endoscopic bougienage.

    The purpose of this study was to describe the mammographic and sonographic appearances and the clinical-pathologic features of invasive micropapillary carcinoma. Between December 1999 and March 2005, among the 3,109 patients who underwent operation for breast cancer, 25 patients proved to have invasive micropaillary carcinoma. Among the 25 patients, we included 22 patients (mean age: 48, range: 26-77 years) who had undergone preoperative mammography and ultrasound. The mammographic and sonographic findings of the lesions were analyzed retrospectively. The pathologic findings were analyzed via the clinical records and pathology reports. Patients manifested with a palpable mass (77%, 17/22), bloody nipple discharge (14%, 3/22) or incidental lesion on the screening mammography (9%, 2/22). On mammography, a mass with an irregular (86%, 12/14) shape and an indistinct (43%, 6/14) or spiculated (43%, 6/14) margin was the most common findings on mammography. On sonography, a hypoechoic (91%, 20/22) mass with irregular shape (73%, 16/22) and an indistinct (32%, 7/22) or microlobulated (32%, 7/22) margin was the most common findings. Pathologically, axillary lymph node metastasis was present in 73% (16/22) of the patients. Invasive micropapillary carcinoma appeared an irregular shaped mass with an indistinct margin mass or microcalcifications on mammography and/or sonography. The tumors were frequently associated with axillary lymph node metastasis

  20. Improving clinical trial design for hepatocellular carcinoma treatments

    2011-12-01

    Full Text Available Despite its place as the third leading cause of cancer deaths worldwide, there are currently no approved chemotherapeutic agents, devices or techniques to treat hepatocellular carcinoma. Importantly, there have been no phase III studies demonstrating survival benefit, nor any randomized studies of treatment except for transarterial chemoembolization and most recently sorafenib. The importance of well-designed clinical trials of agents to treat HCC has never been greater. However, general clinical study design issues, combined with HCC-specific issues pose significant challenges in structuring such studies. HCC-related challenges include the heterogeneity of this cancer and the fact that it is frequently accompanied by significant comorbidities at diagnosis, such as active hepatitis B or C virus replication, substantial past or on-going alcohol use, and cirrhosis, itself often a fatal disease. The recently published comparison of a newer treatment, nolatrexed to doxorubicin, and comments about this study’s initial HCC diagnostic criteria, staging system, comparator therapy and choice of endpoints have provided a platform to discuss the challenges unique to the design of HCC clinical trials. The difficulty in accurately framing study results obtained from the constantly changing HCC clinical landscape and approaches to meet these challenges will be reviewed.

    Hepatocellular carcinoma (HCC) remains the commonest malignancy of the liver. In spite of the recent advances in treatment, prognosis is still abysmal especially in developing countries. This article aims to review the clinical and pathological features of HCC in a tertiary hospital at Nnewi. This was a cross-sectional study. Patients with HCC seen at the Medical Out-patient Department or admitted into the Medical wards of the Nnamdi Azikiwe University Teaching Hospital Nnewi were recruited. The study lasted from June 2007 to May, 2008. Subjects were clinically evaluated and blood samples collected for HBsAg, anti-HCV and HBeAg assays. The prevalence of HCC was 2.4%. Of the 60 patients studied, 38 were males and 22 were females with a male to female ratio of 2:1. Their ages ranged from 19-86 years with a mean age of 50.62 +/- 17.54. The mean duration of symptoms before presentation was 16 weeks and the mean duration from onset of symptoms to death is 20 weeks. Common presenting symptoms were painful right hypochondrial mass, abdominal swelling, weight loss, early satiety and fatigue while coagulopathy, ascites and hepatic encephalopathy were the most common complications. Multiple lesions affecting both lobes of the liver was seen in 48 patients on ultrasound, 36.6% were positive for HBsAg of which 41% were HBeAg positive. HCV antibodies were present in 8.3% of the patients. Well differentiated HCC of the pseudo-glandular variety was the most common histological type. HCC affects middle aged Nigerians. Though well differentiated, it presents late with clinical features of advanced disease leading to death within six months. It is more often associated with chronic HBV than HCV infection.

    Full Text Available Abstract Background Hypoxia-inducible factor 1 (HIF-1 is a transcription factor, which plays a central role in biologic processes under hypoxic conditions, especially concerning tumour angiogenesis. HIF-1α is the relevant, oxygen-dependent subunit and its overexpression has been associated with a poor prognosis in a variety of malignant tumours. Therefore, HIF-1α expression in early stage oral carcinomas was evaluated in relation to established clinico-pathological features in order to determine its value as a prognostic marker. Methods 85 patients with histologically proven surgically treated T1/2 squamous cell carcinoma (SCC of the oral floor were eligible for the study. Tumor specimens were investigated by means of tissue micro arrays (TMAs and immunohistochemistry for the expression of HIF-1. Correlations between clinical features and the expression of HIF-1 were evaluated by Kaplan-Meier curves, log-rank tests and multivariate Cox regression analysis. Results HIF-1α was frequently overexpressed in a probably non-hypoxia related fashion. The expression of HIF-1α was related with a significantly improved 5-year survival rate (p Conclusion HIF-1α overexpression is an indicator of favourable prognosis in T1 and T2 SCC of the oral floor. Node negative patients lacking HIF-1α expression may therefore be considered for adjuvant radiotherapy.

    Basal cell carcinoma (BCC) is the most common malignancy. Exposure to sunlight is the most important risk factor. Most, if not all, cases of BCC demonstrate overactive Hedgehog signaling. A variety of treatment modalities exist and are selected based on recurrence risk, importance of tissue preservation, patient preference, and extent of disease. The pathogenesis, epidemiology, clinical features, diagnosis, histopathology, and management of BCC will be discussed in this review. PMID:26029015

    Sunitinib is an oral, multitargeted tyrosine kinase inhibitor that has been approved for the treatment of metastatic renal cell carcinoma. Although the majority of sunitinib-treated patients receive a clinical benefit, almost a third of the patients will not respond. Currently there is no available marker that can predict for response in these patients. We estimated the plasma levels of NT-pro-BNP (the N-terminal precursor of brain natriuretic peptide) in 36 patients that were treated with sunitinib for metastatic clear-cell renal carcinoma. From the 36 patients, 9 had progressive disease and 27 obtained a clinical benefit (objective response or disease stabilization). Increases in plasma NT-pro-BNP were strongly correlated to clinical outcome. Patients with disease progression increased plasma BNP at statistically significant higher levels than patients that obtained a clinical benefit, and this was evident from the first 15 days of treatment (a three-fold increase in patients with progressive disease compared to stable NT-pro-BNP levels in patients with clinical benefit, p < 0.0001). Median progression-free survival was 12.0 months in patients with less than 1.5 fold increases (n = 22) and 3.9 months in patients with more than 1.5 fold increases in plasma NT-pro-BNP (n = 13) (log-rank test, p = 0.001). This is the first time that a potential 'surrogate marker' has been reported with such a clear correlation to clinical benefit at an early time of treatment. Due to the relative small number of accessed patients, this observation needs to be further addressed on larger cohorts. More analyses, including multivariate analyses are needed before such an observation can be used in clinical practice

    The purpose of the present paper was to review the results of treating early stages glottic, squamous cell carcinoma by radiotherapy in the Department of Radiation Oncology, Prince of Wales Hospital, Sydney. A retrospective review was carried out of all patients seen in the department from 1967 to 1994, inclusive. To be eligible, patients had to have newly diagnosed cancer and to have been treated with curative intent by radiotherapy alone. Three hundred and sixty-nine patients satisfied the eligibility requirements. The mean follow-up time was 12.2 years (maximum: 28 years). At 5 years the actuarial local control rate was 80% (84% for stage T 1 and 72% for T 2 ). The ultimate local control rate was 96%. The overall survival rates at 5 and 10 years were 73% and 52%, respectively. The risk of nodal recurrence was much higher after persisting disease or local recurrence. Our results confirm the high cure rates achieved with this modality of treatment and are comparable with those reported in the literature. Copyright (1999) Blackwell Science Pty. Ltd

    Purpose: To compare directly the effect of intensity-modulated radiotherapy (IMRT) vs. conventional radiotherapy (CRT) on salivary flow and quality of life (QoL) in patients with early-stage nasopharyngeal carcinoma (NPC). Methods and Materials: Fifty-one patients with T2, N0/N1, M0 NPC took part in a randomized controlled clinical study and received IMRT or CRT. Stimulated whole (SWS) and parotid (SPS) saliva flow were measured and Medical Outcomes Short Form 36 (SF-36), European Organization for Research and Treatment of Cancer (EORTC) core quetionnaire, and EORTC head-and-neck module (QLQ-H and N35) were completed at baseline and 2, 6, and 12 months after radiotherapy. Results: Forty-six patients (88%) were in disease remission 12 months after radiotherapy. At 12 months postradiotherapy, 12 (50.0%) and 20 patients (83.3%) in the IMRT group had recovered at least 25% of preradiotherapy SWS and SPS flow respectively, compared with 1 (4.8%) and 2 patients (9.5%), respectively, in the CRT group. Global health scores showed continuous improvement in QoL after both treatments (p < 0.001). However, after 12 months subscale scores for role-physical, bodily pain, and physical function were significantly higher in the IMRT group, indicating a better condition (p < 0.05). Dry mouth and sticky saliva were problems in both groups 2 months after treatment. In the IMRT group, there was consistent improvement over time with xerostomia-related symptoms significantly less common than in the CRT group at 12 months postradiotherapy. Conclusions: IMRT was significantly better than CRT in terms of parotid sparing and improved QoL for early-stage disease. The findings support the case for assessment of health-related QoL in relation to head-and-neck cancer using a site-specific approach

    The most significant feature of early carcinoma, be defined as the gastric carcinoma confined in mucosa and submucosal regardless of its size and shape, is its excellent prognosis; 5 year survival rate after operation in early stomach carcinoma amounts to 93 percent in comparison with around 25 percent in advanced carcinoma, and so the detection of this early stomach carcinoma is most important subject to minimize the mortality from stomach carcinoma at the present time. For the diagnosis of the early stomach carcinoma the radiographic study, cytology and gastroscopic examination are practised, and of those the radiographic study has been revealed commonly best results, but by usual method of upper G-I study it is often difficult to diagnose accurately. Therefore, we have been employed the barium and air double contrast method by insertion of the gastric tube. This method is simple and by this method, the adequate amount of air may introduced into the stomach for the best visualization of the mucosal pattern and gastric juice may also aspirated in a case of which the stomach wall could not be coated by barium because of excessive gastric juice. Summary of the results of this studies of early carcinoma detection at the department of radiology, Severance Hospital during 6 months since May 1969 are as followings; of 1407 cases taken upper G-I study with double contrast method, 17 cases were diagnosed as possible early stomach carcinoma radiographically, and then only 6 cases had surgical resection of stomach. Of these 2 cases were confirmed pathologically and one was considered as precancerots lesion.

    Seventy patients of oral carcinoma, including lip and tongue cancer, were treated at University of Tsukuba Hospital from March 1988 to March 1998. Treatment for each patient was determined according to TNM classification (UICC, 1987). Eight cases of non-squamous cell carcinoma, which were insensitive to radiation or chemotherapy, were surgically treated. Out of 70 cases, sixty-two were pathologically categorized as squamous cell carcinoma (SCC). For SCC cases of stage I or II, full-dose irradiation, including brachytherapy as well as conventional irradiation, was fundamentally the treatment of choice, but in six cases surgical treatment was performed after irradiation of 50 Gy in order to assure curability. In cases of stage III or IV, the treatment of choice was a combination of the surgery and radiotherapy. Fifteen cases, however, were treated only by conventional radiotherapy, brachytherapy (RALS) and/or chemotherapy, because of the patient's refusal to surgery, local or systemic condition, his or her age, and so on. Our treatment plans have consequently resulted in the overall 5-year survival rate of 75.2% for oral SCC. (author)

    Renal cell carcinoma (RCC) is rare in children and comprises only 1-3% of all pediatric primary renal tumors. Recently, several case reports have described RCC developing in patients previously treated for advanced stage neuroblastoma (NB). Our experience with four patients treated for advanced stage NB during early childhood who developed RCC later in life are added to 14 others in the literature. These patients and our review of the literature suggest an association between RCC and NB that warrants further study. (orig.)

    2012-08-01

    Full Text Available Abstract Centrally necrotizing carcinoma is a rare subtype of breast carcinoma, which is characterized by an extensive central necrotic zone accounting for at least 70% of the cross-sectional area of the neoplasm. This central necrotic zone, in turn, is surrounded by a narrow rim of proliferative viable tumor cells. We report an unusual clinical situation in which a patient whose evident breast mass suggested an ipsilateral local recurrence and for which numerous attempts to confirm the histological diagnosis had failed. The patient was treated with a radical mastectomy based on clinical suspicion of breast cancer recurrence after an undesirable delay. In this case, the narrow rim of viable malignant tissue had a thickness of 0.5 to 8 mm, and the centrally necrotizing carcinoma had a central zone with a predominance of fibrosis. The special features of this case led to a misdiagnosis and to an evident clinical local recurrence.

    Clinically evident colonic metastasis from renal cell carcinoma (RCC) is rare. In the present study a hypervascular sigmoid mass was demonstrated on arterial-phase helical CT using a water enema in a patient who had suffered left nephrectomy 8 years previously for RCC. The intense and early enhancement of the lesion suggested the possibility of a solitary colonic metastasis from RCC, a diagnosis which was pathologically confirmed. (orig.)

    The purpose of this study was to commission and clinically test a robotic stereotactic delivery system (CyberKnife, Sunnyvale, CA) to treat early-stage glottic laryngeal cancer. We enrolled 15 patients with cTis-T2N0M0 carcinoma of the glottic larynx onto an institutional review board (IRB)-approved clinical trial. Stereotactic body radiotherapy (SBRT) plans prescribed 45 Gy/10 fractions to the involved hemilarynx. SBRT dosimetry was compared with (1) standard carotid-sparing laryngeal intensity-modulated radiation therapy (IMRT) and (2) selective hemilaryngeal IMRT. Our results demonstrate that SBRT plans improved sparing of the contralateral arytenoid (mean 20.0 Gy reduction, p <0.001), ipsilateral carotid D{sub max} (mean 20.6 Gy reduction, p <0.001), contralateral carotid D{sub max} (mean 28.1 Gy reduction, p <0.001), and thyroid D{sub mean} (mean 15.0 Gy reduction, p <0.001) relative to carotid-sparing IMRT. SBRT also modestly improved dose sparing to the contralateral arytenoid (mean 4.8 Gy reduction, p = 0.13) and spinal cord D{sub max} (mean 4.9 Gy reduction, p = 0.015) relative to selective hemilaryngeal IMRT plans. This “phantom-to-clinic” feasibility study confirmed that hypofractionated SBRT treatment for early-stage laryngeal cancer can potentially spare dose to adjacent normal tissues relative to current IMRT standards. Clinical efficacy and toxicity correlates continue to be collected through an ongoing prospective trial.

    We performed dynamic CT in 30 cases of hepatocellular carcinoma, and concluded as below. Detecting the stain in the early phase of the dynamic series, it is possible to make a diagnosis of hepatocellular carcinoma. The dynamic CT is effective in a case of small hepatocellular carcinoma in which it is difficult to gain an accurate diagnosis in the routine CT study. The dynamic CT is also effective in the differential diagnosis of hepatic lesions, as other hepatic lesions such as hemangioma and metastatic liver cancer show different patterns compared with hepatocellular carcinoma.

    1983-01-01

    Cholangiograms and clinical histories of 82 patients with biopsy-proved bile duct carcinoma were reviewed. The carcinomas were classified according to morphologic findings and clinical outcome. Ulcerative colitis and antecedent inflammatory disease of the biliary tree, particularly primary sclerosing cholangitis, seem to predispose to the development of bile duct carcinoma. Focal stenotic lesions were the most common morphologic type (62/82). Polypoid carcinomas and diffuse sclerosing carcinomas were less common and of about equal frequency. Prognosis was best for patients with polypoid carcinomas and worst for those with diffuse sclerosing carcinomas. In 69 cases (84%), the tumors involved the intrahepatic or proximal extrahepatic ducts, makin curative resection difficult or impossible. Patients with carcinomas limited to the more distal extrahepatic bile ducts had a longer average survival and a higher probability of surgical cure. Proper management of patients with bile duct carcinoma requires a complete and accurate cholangiographic evaluation of the morphology, location, and extent of the disease

    Current conventional treatment modalities in head and neck squamous cell carcinoma (HNSCC) are nonselective and have shown to cause serious side effects. Unraveling the molecular profiles of head and neck cancer may enable promising clinical applications that pave the road for personalized cancer treatment. We examined copy number status in 36 common oncogenes and tumor suppressor genes in a cohort of 191 oropharyngeal squamous cell carcinomas (OPSCC) and 164 oral cavity squamous cell carcinomas (OSCC) using multiplex ligation probe amplification. Copy number status was correlated with human papillomavirus (HPV) status in OPSCC, with occult lymph node status in OSCC and with patient survival. The 11q13 region showed gain or amplifications in 59% of HPV-negative OPSCC, whereas this amplification was almost absent in HPV-positive OPSCC. Additionally, in clinically lymph node-negative OSCC (Stage I–II), gain of the 11q13 region was significantly correlated with occult lymph node metastases with a negative predictive value of 81%. Multivariate survival analysis revealed a significantly decreased disease-free survival in both HPV-negative and HPV-positive OPSCC with a gain of Wnt-induced secreted protein-1. Gain of CCND1 showed to be an independent predictor for worse survival in OSCC. These results show that copy number aberrations, mainly of the 11q13 region, may be important predictors and prognosticators which allow for stratifying patients for personalized treatment of HNSCC.

    We present a case of chordoma in a patient who had been previously treated for ductal carcinoma of the breast. The initial clinical findings and radiological studies suggested a possibility of metastases. However, the findings also adhered to the classical presentations and findings of the chordoma of the base of skull. It was only after the surgical resection and immunohistochemical confirmation that the diagnosis of chordoma could be established. Here, we discuss chordoma with the analysis of our clinical intrigue.

    Acinic cell carcinomas of the parotid should be considered distinct malignancies despite descriptions of low-grade malignant potential and innocuous histologic patterns. Benign-appearing tumors frequently have a clinically malignant course. Blood-borne metastases may oocur early despite gross and microscopic innocence. Indolent growth may be a characteristic of local disease, which may then be approached with less than radical parotidectomy and sacrifice of the facial nerve. These tumors prove to be radiosensitive. More agressive postoperative irradiation and palliative irradiation is recommended. Two cases of successful palliation of spinal metastases are presented as examples of radiosensitivity of this tumor

    Highlights: Black-Right-Pointing-Pointer Overexpression of Ku86 in human liver cancer was shown by immunohistochemistry. Black-Right-Pointing-Pointer Serum anti-Ku86 was significantly elevated in early hepatocellular carcinoma. Black-Right-Pointing-Pointer Anti-Ku86 may be more sensitive than the conventional markers for early detection. Black-Right-Pointing-Pointer Serum anti-Ku86 significantly decreased after surgical resection of liver tumors. Black-Right-Pointing-Pointer Elevation of serum anti-Ku86 in other non-liver solid tumors was minimal. -- Abstract: Hepatocellular carcinoma (HCC), the predominant form of primary liver cancer, is one of the most common cancers worldwide and the third most common cause of cancer-related death. Imaging studies including ultrasound and computed tomography are recommended for early detection of HCC, but they are operator dependent, costly and involve radiation. Therefore, there is a need for simple and sensitive serum markers for the early detection of hepatocellular carcinoma (HCC). In our recent proteomic studies, a number of proteins overexpressed in HCC tissues were identified. We thought if the serum autoantibodies to these overexpressed proteins were detectable in HCC patients. Of these proteins, we focused on Ku86, a nuclear protein involved in multiple biological processes and aimed to assess the diagnostic value of serum anti-Ku86 in the early detection of HCC. Serum samples were obtained prior to treatment from 58 consecutive patients with early or relatively early hepatitis C virus (HCV)-related HCC and 137 patients with HCV-related liver cirrhosis without evidence of HCC. Enzyme immunoassays were used to measure serum levels of autoantibodies. Serum levels of anti-Ku86 antibodies were significantly elevated in HCC patients compared to those in liver cirrhosis patients (0.41 {+-} 0.28 vs. 0.18 {+-} 0.08 Abs at 450 nm, P < 0001). Setting the cut-off level to give 90% specificity, anti-Ku86 was positive in 60.7% of

    The vaginal smear specimens of the patients who received operative therapy, irradiation or chemotherapy for cervical carcinoma were examined. Long-term follow-up vaginal cytology following treatment of cervical carcinoma is effective for the detection of local recurrence in an early stage. Serial cytology is also useful in evaluation of the effects of irradiation and chemotherapy for cervical carcinoma. Radiosensitive and prognostic significance of vaginal smears before and after radiation therapy was discussed. (author)

    To describe the clinico-pathological and radiological profile of hepatocellular carcinoma. All consecutive patients suspected of having hepatocellular carcinoma (HCC), were admitted and included in this study. Diagnosis of HCC was established by clinical, biochemical, ultrasonographic and histopathologic findings. Patients with primary carcinoma elsewhere in the body, metastatic in the liver, fibrolamellar carcinoma and benign tumours were excluded from the study. At ultrasonography, the details of tumour size and number, portal vein thrombosis and presence of ascites were recorded. Patients were staged according to Okuda staging system. Results were described in mean and percentage values. There were 82 patients with hepatocellular carcinoma including 58 males and 24 females, with male to female ratio of 2.8:1. The mean age of patients was 56.24 +- 13.65 years. Right hypochondrial pain was the main symptom in 52 (63.4%) patients. The duration of symptoms varied from 1 month to 2 years. Tumour size was larger than 50% of liver size in 42 (51.2%) with portal vein thrombosis in 10 (12.19%). Anti HCV was positive in 44 (53.7%), HBsAg in 26 (31.7%) and both were found positive in 2 (2.44%) patients. Ten patients (12.2/%) found negative both for anti-HCV and HBsAg. According to Okuda staging system 18 patients had stage 1, 50 had stage 2 and 14 had stage 3 hepatocellular carcinoma. The mean age of presentation of hepatocellular carcinoma was younger as compared to western countries with potentially large non-resectable lesions. Chronic hepatitis C and B was found to be the major known factors. Patients with chronic hepatitis C and B should undergo vigorous HCC surveillance to detect early, potentially respectable HCC.

    2013-01-01

    Full Text Available We report a case of Wegener’s granulomatosis clinically mistaken for carcinoma in a 21-year-old girl presenting with an ulcerated mass of the nasopharynx associated with enlarged laterocervical nodes. The lesion was clinically suspected as malignant on the basis of clinical and radiological findings (namely, computed tomography scan and positron emission tomography. However, multiple biopsies were not conclusive for malignancy showing histological change suggestive of Wegener’s granulomatosis. A serum determination of cANCA supported the diagnosis of Wegener’s granulomatosis. Clinical findings and image studies suggested an erroneous diagnosis of malignancy whereas a definitive diagnosis of Wegener’s granulomatosis was achieved only after repeated biopsies thus leading to a correct therapeutic approach. The Wegener granulomatosis must be added to the list of the differential diagnoses of the masses of the nasopharynx associated with or without enlarged laterocervical nodes.

    Poorly differentiated thyroid carcinoma (PDTC) has been recognized for the past 30 years as an entity showing intermediate differentiation and clinical behavior between well-differentiated thyroid carcinomas (ie, papillary thyroid carcinoma and follicular thyroid carcinoma) and anaplastic thyroid carcinoma; however, there has been considerable controversy around the definition of PDTC. In this review, the evolution in the definition of PDTC, current diagnostic criteria, differential diagnoses, potentially helpful immunohistochemical studies, and molecular alterations are discussed with the aim of highlighting where the diagnosis of PDTC currently stands.

    Purpose: To summarize biochemical failure rates and morbidity of external beam irradiation (EBRT) combined with palladium ( 103 Pd) boost for clinically localized high-risk prostate carcinoma. Methods and Materials: Seventy-three consecutive patients with stage T2a-T3 prostatic carcinoma were treated from 1991 through 1994. Each patient had at least one of the following risk factors for extracapsular disease extension: Stage T2b or greater (71 patients), Gleason score 7-10 (40 patients), prostate specific antigen (PSA) >15 (32 patients), or elevated prostatic acid phosphatase (PAP) (17 patients). Patients received 41 Gy EBRT to a limited pelvic field, followed 4 weeks later by a 103 Pd boost (prescription dose: 80 Gy). Biochemical failure was defined as a PSA greater than 1.0 ng/ml (normal 103 Pd brachytherapy for clinically localized, high-risk prostate cancer compare favorably with that reported after conventional dose EBRT alone. Morbidity has been acceptable

    This guide aims at providing practitioners taking into care patients presenting a cutaneous cancer with recommendations based on scientific evidences or expert agreements. More precisely, the objectives are to clarify the terminology used to describe the different forms of cutaneous epidermoid carcinoma (CEC) and of their precursors (actinic keratosis, Bowen's disease), to propose a prognosis classification of CECs adapted to the previously identified prognosis factors, to optimise the diagnosis and therapy of actinic keratosis and Bowen's disease according to recent publications, and to recall the principles of a primary prevention of CECs and of their precursors, and of screening of high risk individuals. Thus, the different parts of this report address the following issues: anatomic-clinical forms and epidemiology of CECs and of their precursors, prognosis factors of CECs, means of treatment of CECs and of their precursors (medical, physical, surgical, radiation-based, and chemical treatments). Radiotherapy notably comprises external radiotherapy and interstitial brachytherapy. Indications for radiotherapy are discussed with respect to existing guides and to the clinical situation. The authors address the care of CECs and of their precursors (prevention, screening and clinical diagnosis, care of invasive CECs, keratoacanthoma treatment). They finally discuss quality criteria aimed at practice improvement, and perspectives regarding the evolution of this guide and studies to be performed

The discovery of the involvement of microRNAs (miRNAs in hepatocarcinogenesis represents an important area of investigation for the development of their clinical applications. These molecules may act as oncogenes or tumor suppressors by directly or indirectly controlling the expression of key proteins involved in cancer-associated pathways. On the clinical side, because of their tumor-specific expression and stability in tissues and in the circulation, miRNAs have been proposed as novel diagnostic tools for classification and prognostic stratification of HCC. In recent years, the therapeutic potential of miRNAs has been demonstrated in various preclinical studies. Anti-miRNA oligonucleotides and miRNA mimics have been found to have antitumor activity. Moreover, by exploiting tumor-specific expression of miRNA, efforts have been aimed at improving targeting of tumor cells by replicative oncolytic viruses while sparing normal cells. These areas are expected to be explored further in the upcoming years to assess the clinical value of miRNA-based approaches in HCC and cancer in general.

    2004-01-01

    Invasive lobular carcinoma (ILC) comprises approximately 10% of breast cancers and appears to have a distinct biology. Because it is less common than infiltrating ductal carcinoma (IDC), few data have been reported that address the biologic features of ILC in the context of their clinical outcome. In the present study we undertook an extensive comparison of ILC and IDC using a large database to provide a more complete and reliable assessment of their biologic phenotypes and clinical behaviors. The clinical and biological features of 4140 patients with ILC were compared with those of 45,169 patients with IDC (not otherwise specified). The median follow-up period was 87 months. In comparison with IDC, ILC was significantly more likely to occur in older patients, to be larger in size, to be estrogen and progesterone receptor positive, to have lower S-phase fraction, to be diploid, and to be HER-2, p53, and epidermal growth factor receptor negative. It was more common for ILC than for IDC to metastasize to the gastrointestinal tract and ovary. The incidence of contralateral breast cancer was higher for ILC patients than for IDC patients (20.9% versus 11.2%; P < 0.0001). Breast preservation was modestly less frequent in ILC patients than in IDC patients. The 5-year disease-free survival was 85.7% for ILC and 83.5% for IDC (P = 0.13). The 5-year overall survival was 85.6% for ILC and 84.1% for IDC (P = 0.64). Despite the fact that the biologic phenotype of ILC is quite favorable, these patients do not have better clinical outcomes than do patients with IDC. At present, management decisions should be based on individual patient and tumor biologic characteristics, and not on lobular histology

The early phases are asymptomatic and the prognosis is poor, which makes prevention essential. We propose that non-selective beta-blockers decrease the incidence and growth of hepatocellular...... and growth of hepatocellular carcinoma. Rodent and in vitro studies support the hypothesis, but clinical verification is needed. Different study designs may be considered. The feasibility of a randomized controlled trial is limited due to the necessary large number of patients and long follow......-up. Observational studies carry a high risk of bias.

    Full Text Available Background: Oral cancer ranks in the top three of all cancers in India, which accounts for over 30% of all cancers reported in the country. The micronucleus test (MNT is one of the most widely applied short term tests used in genetic toxicology to evaluate the mutagenicity and carcinogenicity. Aims: The present study aims at an in vivo cytogenetic analysis of human oral squamous cell carcinoma and to assess the applicability of MNT in diagnosing early detection of oral carcinoma. Materials and Methods: Exfoliated scrape smears were collected from the clinically diagnosed 136 patients suffering from oral precancerous and cancerous lesions. The wet fixed smears were stained by adopting Papanicolaou's staining protocol and counter-stained with Giemsa's solution. Results: The frequency of micronucleated cells has been observed to be in increasing order with the increase of the age-groups and from control to precancerous to cancerous cases significantly in both sexes. Conclusion: Micronucleus formation in the oral mucosa could be a biomarker of genetic damage and also a potential onco-indicator in the long run of oral carcinogenesis. Therefore, MNT can be applied for the early detection of oral carcinoma in the human being.

    Renal cell carcinoma (RCC) continues to increase in incidence with the largest increase manifesting in small, organ-confined tumors. This review outlines the epidemiology and current data pertaining to the management of clinically-localized RCC. In this manuscript, the current data outlining the benefit of nephron sparing to the overall survival of the patient is described. The data pertaining to minimally invasive nephron sparing is also explained in detail. From laparoscopic and robotic partial nephrectomy to watchful waiting and percutaneous ablation, the urologist is continually assaulted with new data for the management of clinically-localized RCC. The data can be confusing, and much of it is conflicting. The addition of new scoring systems or nomograms may aid in predicting which therapy would be most beneficial in certain patient groups. New scoring systems may also predict the difficulty of surgical resection and predict surgical complications. The limitations of the data pertaining to the management of clinically-localized RCC are also outlined.

    Using MR imaging with a body coil parametrial invasion was determined prospectively in 169 consecutive patients considered on the basis of clinical examination to have carcinoma confined to the cervix. After radical hysterectomy correlation with histologic examination was performed for the left and right parametrium separately. The criterion for parametrial invasion was a high-signal-intensity lesion with disruption of the full thickness of the cervical stroma combined with areas of abnormal signal intensity within the parametrial region on T2-weighted images. Histologic examination showed that 18 parametria in 13 patients were invaded by tumor. MR had an overall accuracy of 93%, a sensitivity of 89%, and a specificity of 93% in demonstrating parametrial involvement. Positive and negative predictive values were 43% and 99%. The main weakness of MR was 21 false-positive tests. This represents a limitation when MR is performed with a body coil. (orig.)

    Objectives: To assess the frequency of carcinoma in clinically benign prostatic hyperplasia and role. of digital rectal examination (DRE) and prostatic specific antigen (PSA) in assessment of these patients. Data source: Patients admitted to the Department of Urology and Renal Transplantation with lower urinary tract symptoms (LUTS) due to enlarged prostate. Design of study: Descriptive Study Place and Duration of Study: Department of Urology and Renal Transplantation, Quaid-e-Azam Medical College Bahawal Victoria Hospital, Bahawalpur, from January 2007 to December 2010. Patients and Methods: Patients presenting with lower urinary tract symptoms over the age of 50 years were evaluated on International Prostate Symptoms Score (IPSS), clinically examined and post-voiding residual urine determined on abdominal ultrasonography. The selection criteria were; Refractory retention of urine, Severe IPSS, absence of signs of malignancy on Digital Rectal Examination (DRE) and post-voiding residual urine more than 100 mI. Thus a total 300 patients were selected. Patient's blood sample was sent to laboratory to assess Prostate Specific Antigen (PSA) level pre-operatively. All these patients underwent either transurethral resection of prostate (TURP) or transvesical prostatectomy (TVP) and prostatic tissue was sent for histopathology. Results: In this study, 13.33% patients were found to have carcinoma of prostate in spite of being clinically benign prostates in all patients, irrespective of PSA range. The PSA value was found 4ngjml. In this study, 9.95% patients had carcinoma prostate in spite having normal PSA and benign prostate on DRE while with rising PSA levels and normal DRE, chances of malignancy detection increases (66.67% ). Conclusion: We conclude that although frequency is low the possibility of malignancy in clinically benign enlarged prostate should be borne in mind whenever subjecting the patient for screening, assessment and treatment. DRE alone is insufficient

    This study investigated the expression of wingless-type inhibitory factor-1 (WIF-1) and Ihh protein in tumor tissues and their clinical significance in patients with lung squamous cell carcinoma and adenocarcinoma. The expression of WIF-1 and Ihh protein in 74 squamous cell carcinomas and 76 adenocarcinomas was measured by immunohistochemistry. The percentage of positive WIF-1 protein expression was significantly higher, while positive Ihh protein expression was significantly lower in patients with well-differentiated lung squamous cell carcinoma and adenocarcinoma, tumor node metastasis (TNM) stage I disease, and lymph node metastasis than that in patients with poorly differentiated tumor, TNM stage III disease, and lymph node metastasis (PIhh protein expression survived significantly shorter than patients with negative Ihh protein expression. In contrast, no significant difference in mean survival was observed in patients with lung squamous cell carcinoma and adenocarcinoma with positive and negative WIF-1 protein expression (P>0.05). Ihh is a marker for poor prognosis in patients with lung squamous cell carcinoma and adenocarcinoma. WIF-1 is not a predictive marker for lung cancer.

    Hepatocellular carcinoma is one of the most prevalent neoplasms and the leading cause of cancer-related mortality worldwide. Mitochondrial ribosomal protein S23 is encoded by a nuclear gene and participates in mitochondrial protein translation. Mitochondrial ribosomal protein S23 overexpression has been found in many types of cancer. In this study, we explored mitochondrial ribosomal protein S23 expression in primary hepatocellular carcinoma tissues compared with matched adjacent non-tumoral liver tissues using mitochondrial ribosomal protein S23 messenger RNA and protein levels collected from public databases and clinical samples. Immunohistochemistry was performed to analyze the relationship between mitochondrial ribosomal protein S23 and various clinicopathological features. The results indicated that mitochondrial ribosomal protein S23 was significantly overexpressed in hepatocellular carcinoma. High mitochondrial ribosomal protein S23 expression was correlated with the tumor size and tumor-metastasis-node stage. Moreover, patients with high mitochondrial ribosomal protein S23 expression levels presented poorer survival rates. Mitochondrial ribosomal protein S23 was an independent prognostic factor for survival, especially at the early stage of hepatocellular carcinoma. In addition, the downregulation of mitochondrial ribosomal protein S23 decreased the proliferation of hepatocellular carcinoma in vitro and in vivo. In conclusion, we verified for the first time that mitochondrial ribosomal protein S23 expression was upregulated in hepatocellular carcinoma. High mitochondrial ribosomal protein S23 levels can predict poor clinical outcomes in hepatocellular carcinoma, and this protein plays a key role in tumor proliferation. Therefore, mitochondrial ribosomal protein S23 may be a potential therapeutic target for hepatocellular carcinoma.

    The Gorlin-Goltz syndrome, also known as nevoid basal cell carcinoma syndrome (NBCCS), is an infrequent multisystemic disease inherited in a dominant autosomal way, which shows a high level of penetrance and variable expressiveness. It is characterized by keratocystic odontogenic tumors (KCOT) in the jaw, multiple basal cell nevi carcinomas and skeletal abnormities. This syndrome may be diagnosed early by a dentist by routine radiographic exams in the first decade of life, since the KCOTs are usually one of the first manifestations of the syndrome. This article paper reports the case of a patient, a 10-year-old boy with NBCCS, emphasizing its clinical and radiographic manifestations. This study highlights the importance of health professionals in the early diagnosis of NBCCS and in a preventive multidisciplinary approach to provide a better prognosis for the patient.

    To evaluate carcinoma of the cervix using magnetic resonance imaging (MRI), correlate with clinical approach of International Federation of Gynecology and Obstetrics (FIGO) staging system and to study the impact of MRI findings on patient management. Pathologically confirmed, 75 cases of carcinoma cervix referred to our institute from April 2007 to March 2008 were prospectively studied. Clinical FIGO stage was assigned to each patient by gynaecologists blinded to MRI findings. MRI stage (based on FIGO and TNM) was allotted by radiologists blinded to clinicopathological details. For patients who were operated, histopathological stage was taken as gold standard. For patients who were not operated, gynaecologists decided on a gold standard stage based on all available clinical and imaging data. MR staging was correlated with FIGO staging, with focus on significant alterations in treatment strategy caused due to MRI findings. MRI staging had an accuracy of 89.3% (67/75), while clinical FIGO staging had 61.3% (46/75) accuracy. MRI staging and FIGO staging concurred in 65.6% of the patients and differed in 34.4% of the patients. In about 30.6% (23/75) of the patients, there were relevant additional MRI findings not suspected clinically. The common significant MRI findings were detection of pelvic lymphadenopathy and clinically unsuspected bowel/bladder invasion. The management protocol was significantly altered in 86.9% (20/23) of the patients with additional MRI findings constituting 26.6% (20/75) of the total population. MRI is highly accurate in evaluating carcinoma of the cervix. MRI findings significantly altered therapeutic decisions in 26.6% of the patients. MRI should be considered prior to treatment planning in every patient.

    40 cases of bile duct carcinoma gathered over a 6-year period at Kosin Medical College were reviewed and their clinical and cholangiographic findings were as follows: 1. There were 29 males and 11 females (the ratio of men to women, 2.6:1) ranging from 37 to 74 years of age. The majority (70% of cases) were in 4th and 5th decades. 2. Clinical symptoms and signs: jaundice in 95%, RUQ or epigastric pain in 75%, pruritus in 52.5%, dark urine in 35%, weight loss in 32.5%, fever and chills in 22.5%, clay colored stool in 12.5%, and palpable mass in 12.5%. 3. Lab. findings: elevated serum total bilirubin (above 20.0mg% in 45%, 10.0-19.9mg% in 22.5%, 5.0-9.9mg% in 20%, 1.3-4.9mg% in 5%), elevated alkaline phosphatase in 95%. Clonorchiasis were noted in 17.5%. 4. Histologic findings were adenocarcinoma in most cases. 5. The location of bile duct carcinoma were common hepatic duct in 35%, common bile duct in 32.5%, porta hepatic in 12.5%, junction with cystic duct in 10% and diffuse form in 10%. 6.

    There is evidence from the literature that the terms "ductal carcinoma in situ" and "lobular carcinoma in situ" (DCIS and LCIS) should be eliminated in clinical breast cancer practice and replaced with the new "ductal intraepithelial neoplasia" (DIN) and "lobular intraepithelial neoplasia" (LIN) terminology. The main purpose of the present article is to expand on this argument from a cognitive psychology perspective and offer suggestions for further research, emphasizing how the elimination of the term "carcinoma" in "in situ" breast cancer diagnoses has the potential to reduce both patient and health care professional confusion and misperceptions that are often associated with the DCIS and LCIS diagnoses, as well as limit the adverse psychological effects of women receiving a DCIS or LCIS diagnosis. We comment on the recent peer-reviewed literature on the clinical implications and psychological consequences for breast cancer patients receiving a DCIS or LCIS diagnosis and we use a cognitive perspective to offer new insight into the benefits of embracing the new DIN and LIN terminology. Using cognitive psychology and cognitive science in general, as a foundation, further research is advocated in order to yield data in support of changing the terminology and therefore, offer a chance to significantly improve the lives and psychological sequelae of women facing such a diagnosis.

    Purpose: Whereas there are many reports regarding treatment of early vocal cord cancer with cobalt 60 or 2-4-MV X-rays, there are still few reports on the results of treatment with 6-MV X-rays. Theoretically, 6-MV X-rays result in greater underdosage of tumor at the air-tissue interface and at the anterior commissure. This paper analyzes the results of irradiation of early and moderately advanced squamous cell carcinoma of the true vocal cord treated exclusively with 6-MV X-rays in a community hospital. The literature pertinent to the issue is reviewed. Methods and Materials: Eighty-three patients with Tis, T1, T2, or T3 squamous cell carcinoma of the true vocal cord were treated with curative intent at Bethesda Memorial Hospital in Boynton Beach, Florida between April 1986 and April 1998. The dose schedules most commonly used were 63 Gy in 28 fractions (2.25 Gy per fraction once a day) for T1 tumors or 74.40 Gy in 62 fractions (1.2 Gy per fraction twice a day) for T2 and T3 tumors. All patients have minimum 2-year follow-up; 63 (76%) have 5-year minimum follow-up. Results: Local control was achieved in 6 of 6 Tis, 53 of 54 (98%) T1, 8 of 8 T2, and 6 of 6 T3 lesions. No complications were encountered. Conclusions: A recent literature review indicates that the treatment of early vocal cord cancer with 6-MV X-rays remains controversial. The dose schedules used in the present paper produced a high rate of local control, a finding that is consistent with reports of other investigators who used dose schedules similar to those used in the present series. However, several other investigators have reported significantly lower rates of local control for T1 or T2 glottic cancer treated with 6-MV X-rays when compared to results obtained with cobalt 60 or 4 MV at their own institution. The latter institutions used lower total doses and/or lower dose per fraction than those institutions reporting high rates of local control with 6 MV. Data from the literature, as well as our

    Uterine cervical cancer is globally the third most common cancer among women, and shows high mortality with invasive cervical carcinoma. Early detection of the disease, its correct staging, and treatment are therefore of great importance. The staging system updated in 2009 by the International Federation of Gynecology and Obstetrics (FIGO), is commonly used for planning the treatment. However, there are significant inaccuracies in the FIGO staging system. Accurate tumor staging is very important to decide the treatment strategy. Although not included in the staging system, magnetic resonance (MR) imaging is a valuable tool for local staging of the disease, and is useful in assessing the spread of the tumor and metastatic lymph nodes, thereby becoming a more accurate substitute for clinical staging of cervical carcinoma. In addition, it is capable of assessing the disease response to surgery or chemoradiation. This review briefly describes the role of MR imaging and the basic MR scanning protocol in evaluating cervical carcinoma. The MR findings with staging, and MR evaluation of treatment response, are further addressed.

    Circulating hepatocellular carcinoma cells may be detected by reverse transcription-polymerase chain reaction. We investigated the relationship between circulating hepatocellular carcinoma cells and hepatoma patient survival after different managements and survival periods. Peripheral vein blood (5 ml) samples were obtained from 113 patients with hepatocellular carcinoma and from 33 control subjects (9 with liver cirrhosis after hepatitis B, 14 with chronic hepatitis B, 10 healthy individuals) between January 1, 2009, and December 31, 2013. To detect circulating hepatocellular carcinoma cells in peripheral blood, alpha-fetoprotein messenger RNA was amplified from total RNA extracted from whole blood by reverse transcription-polymerase chain reaction. Alpha-fetoprotein messenger RNA was detected in 59 blood samples from the hepatocellular carcinoma patients (59/113, 52.2%). In contrast, there were no clinical control subjects whose samples showed detectable alpha-fetoprotein messenger RNA. The presence of alpha-fetoprotein messenger RNA in blood seemed to be correlated with the stage (by TNM classification) of hepatocellular carcinoma, serum alpha-fetoprotein value, and the presence of intrahepatic metastasis, portal vein thrombosis, tumor diameter and/or distant metastasis. In addition, alpha-fetoprotein messenger RNA was detected in the blood of 25 patients showing distant metastasis at extrahepatic organs (100%), in contrast to 32 of 88 cases without metastasis (36.4%). All the patients with hepatocellular carcinoma were followed. Seventeen patients with resection of a T 2 stage hepatocellular carcinoma had a survival of 3.2 years after surgical management, 38 cases with resection of a T3 stage hepatocellular carcinoma had a 1.3-year survival, and only 37 cases with T4 stage disease after different treatments except surgery survived for 0.6 years (P <0.01). The presence of alpha-fetoprotein messenger RNA in peripheral blood may be an indicator of circulating

    Full Text Available The standard treatment approach for squamous cell carcinoma (SCC of the anal canal includes abdominoperineal resection and chemoradiotherapy. However, there are currently very few reports of early SCC of the anal canal resected by endoscopic submucosal dissection (ESD. We report 2 rare cases of SCC of the anal canal resected by ESD. In case 1, a 66-year-old woman underwent a colonoscopy due to blood in her stool, and an elevated lesion, 15 mm in size, was identified from the rectum to the dentate line of the anal canal on internal hemorrhoids. The lesion was diagnosed as an early SCC of the anal canal, and ESD was successfully performed. The histopathological diagnosis was SCC in situ. In case 2, a 71-year-old woman underwent a colonoscopy due to constipation, and an elevated lesion, 25 mm in size, was identified from the dentate line to the anal canal. The lesion was diagnosed as early-stage SCC of the anal canal, and ESD was successfully performed. The histopathological diagnosis was SCC in situ. No complications or recurrence after ESD occurred in either case.

    Objective: Carcinoma of unknown primary (CUP) is not uncommon in usual clinical settings. They are, by definition, those cases with clinically suspected primary malignancy but not revealed by conventional investigation. The aim of this study was to investigate the efficacy of whole-body 18 F-fluoro- deoxyglucose (FDG) PET/CT in detecting a primary neoplasm for these patients. Methods: A totle of 150 patients with retrievable records from 169 CUP patients were selected within a group of consecutive 2589 patients from Jan. 2006 to Jun. 2007. All cases underwent whole-body FDG PET/CT scan. The final diagnoses were confirmed by pathologic results, other imaging modalities or clinical follow-up. Results: Among 150 patients, primary tumor sites were successfully detected by whole-body 18 F-FDG PET/CT scan in 70 cases (46.7%), of which 52 were pathologically confirmed and 18 by clinical follow-up. And 38 cases (54.3%) were lung cancer, 8 (11.4%) were nasopharyngeal carcinoma, 13 (18.6%) in digestive sys- tem, and 11 (15.7%) in other systems. Three clinically suspected CUP cases with negative 18 F-FDG PET/ CT were subsequently confirmed of benign processes by clinical follow-up. Six patients were wrongly diagnosed by 18 F-FDG PET/CT, and 15 patients did not have a confirmed diagnosis by the end of research. The primary cause of malignancy after 18 F-FDG PET/CT remained obscure in 56 patients, only 3 of whom be- came known during the course of clinical follow-up (nasopharyngeal bladder and esophageal carcinoma). Conclusion: 18 F-FDG PET/CT whole-body imaging plays an important role in patients with metastatic CUP. (authors)

    Full Text Available BACKGROUND Breast cancer distribution differs by geography, regional lifestyle, racial or ethnic background. In general, both breast cancer incidence and mortality are relatively lower among the female populations of Asia and Africa, relatively underdeveloped nations, and nations that have not changed to the westernised reproductive and dietary patterns. In contrast, European and North American women from heavily industrialised or westernised countries have a substantially higher incidence of breast cancer. The aim of the study is to1. Analyse the relationship between socioeconomic and educational status and early diagnosis of CA breast. 2. Emphasise the need for early detection of breast cancer. MATERIALS AND METHODS This study was carried out in 150 patients who were admitted in the Department of General Surgery. Inclusion criteria for patients in this study consist of patient of any age presenting with the lesion suspected of breast carcinoma and proved by FNAC and Tru-cut biopsy and all relevant investigations to stage the disease like chest x-ray, ultrasound abdomen, liver function test, mammography and skeletal survey done for advanced cases to rule out metastasis. Patients excluded where those who presented with symptoms of breast on clinical examination, but on investigation, there was no malignant pathology of breast and male patients with breast carcinoma excluded. Patients data was collected in standardised pro forma, which included age, socioeconomic status, level of education, duration of symptoms, detection of lump by the patient or medical practitioner into three class lower, middle and upper. The socioeconomic status defined by Kuppuswamy scale was used in this study. Literacy status classified into illiterate and educated, which is further classified into primary (I-IV, secondary (high school and higher secondary and higher education (graduate and above. RESULTS In our study, among 150 patients, 34% presented in early stage

    Purpose: To investigate whether early-assessed radioresponse of tumors corresponds with late-assessed radioresponse, which is associated with local disease control in radiotherapy (RT) for cervical cancer. Methods and Materials: This prospective study included 12 patients with cervical squamous cell carcinoma treated by RT with or without concurrent cisplatin. Tumor volume was estimated by scheduled magnetic resonance imaging before (preRT), 3 to 4 weeks after (early assessment), and 6 to 7 weeks after (late assessment) RT initiation. Radioresponse was assessed with tumor shrinkage curves based on these volumes. Radioresponse for each tumor was calculated as the slope (day -1 ) of the shrinkage curve by fitting to an exponential equation. Results: Early-assessed radioresponse ranged from 0.001 to 0.106 day -1 (median, 0.021 day -1 ) and late-assessed radioresponse from 0.009 to 0.091 day -1 (median, 0.021 day -1 ), with no significant difference between them (p = 0.1191). The early-assessed radioresponse correlated with the late-assessed radioresponse (R 2 = 0.714, p = 0.0005). Conclusions: Correspondence between early- and late-assessed radioresponse in a series of tumors showing a wide range of radioresponse was not particularly close overall. However, early assessment of radioresponsiveness did seem to be useful for characterizing those tumors with high or low radioresponsiveness

    Colorectal cancer (CRC) screening programs result in the detection of early-stage asymptomatic carcinomas suitable to be surgically cured. Lymph nodes (LN) from early CRC are usually small and may be difficult to collect. Still, at least 12 LNs should be analyzed from colectomies, to ensure a reliable pN0 stage. Presurgical endoscopic tattooing improves LN procurement. In addition, molecular detection of occult LN tumor burden in histologically pN0 CRC patients is associated with a decreased survival rate. We aimed to study the impact of presurgical endoscopic tattooing on the molecular detection of LN tumor burden in early colon neoplasms. A prospective cohort study from a CRC screening-based population was performed at a tertiary academic hospital. LNs from colectomies with and without preoperative endoscopic tattooing were assessed by two methods, hematoxylin and eosin (HE), and RT-LAMP, to detect tumor cytokeratin 19 (CK19) mRNA. We compared the amount of tumor burden and LN yields from tattooed and non-tattooed specimens. HE and RT-LAMP analyses of 936 LNs were performed from 71 colectomies containing early carcinomas and endoscopically unresectable adenomas (8 pT0, 17 pTis, 27 pT1, 19 pT2); 47 out of 71 (66.2 %) were tattooed. Molecular positivity correlated with the presence of tattoo in LN [p < 0.001; OR 3.1 (95 % CI 1.7-5.5)]. A significantly higher number of LNs were obtained in tattooed specimens (median 17 LN vs. 14.5 LN; p = 0.019). Endoscopic tattooing enables the analysis of those LNs most prone to harbor tumor cells and improves the number of LN harvested.

    Epidemiology of hepatocellular carcinoma is changing worldwide. This study aimed at evaluating the changing scenario of aetiology, presentation, management and prognosis of hepatocellular carcinoma in Italy during the last 15 years. Retrospective analysis of the ITA.LI.CA (Italian Liver Cancer) database including 5192 hepatocellular carcinoma patients managed in 24 centres from 2000 to 2014. Patients were divided into three groups according to the date of cancer diagnosis (2000-2004, 2005-2009 and 2010-2014). The main results were as follows: (i) progressive patient aging; (ii) progressive expansion of non-viral cases and, namely, of "metabolic" hepatocellular carcinomas; (iii) increasing proportion of hepatocellular carcinoma diagnosed during a correct (semi-annual) surveillance programme; (iv) favourable cancer stage migration; (v) increased use of radiofrequency ablation to the detriment of percutaneous ethanol injection; (vi) improved outcomes of ablative and transarterial treatments; (vii) improved overall survival (adjusted for the lead time in surveyed patients), particularly after 2009, of both viral and non-viral patients presenting with an early- or intermediate-stage hepatocellular carcinoma. During the last 15 years several aetiological and clinical features of hepatocellular carcinoma patients have changed, as their management. The observed improvement of overall survival was owing both to the wider use of semi-annual surveillance, expanding the proportion of tumours that qualified for curative treatments, and to the improved outcome of loco-regional treatments. © 2016 John Wiley & Sons A/S.

    We present and illustrate the MRI appearances of two children with choroid plexus carcinoma. The MRI characteristics of these rare tumours are reviewed. Since total surgical resection is a significant prognostic factor, early postoperative MRI was performed in both cases to ensure surgical clearance. In one case a complete resection was documented and this patient remains well at short-term follow-up. Residual tumour was noted in the second case, but despite ''second look'' surgery there was subsequent local relapse. (orig.)

    This research was aimed to study the expression of Serine/arginine rich splicing factor 2 (SRSF2) in tissues of hepatocellular carcinoma, and explore the relationship between the expression and the clinic pathological and prognosis of human hepatocellular carcinoma (HCC). One hundred and fifty-three pairs HCC tissues and adjacent normal tissue were collected from January 2010 to March 2013. The expression of SRSF2 gene was detected by immunohistochemistry, western blotting and real-time quantitative polymerase chain reaction (PCR), and the relationship between the expression and the clinic pathological and prognosis of HCC being analyzed. In 153 cases of hepatocellular carcinoma, SRSF2 was highly expressed in 93 cases, low expression of 60 cases, immunohistochemistry score (6.50 ± 2.82), which was significantly higher than that in adjacent normal tissues (2.94 ± 1.23) (Phepatocellular carcinoma was positively correlated (r = 0.704, Phepatocellular carcinoma were 74.19%, 44.09%, 26.88%, 24.73% and 21.51% at 1 year, 2 years, 3 years, 4 years and 5 years respectively, which were lower than those of SRSF2 low expression group (93.33%, 71.67%, 56.67%, 51.67% and 50.00%). SRSF2 is highly expressed in hepatocellular carcinoma and its expression increases with the degree of tumor differentiation and TNM staging. It is related to lymph node metastasis and metastasis of tumor cells, and is positively related to serum alpha fetoprotein content, and affects the postoperative survival time of HCC patients.

    To investigate prognostic significance of clinical and pathological stages in patients with locally advanced rectal carcinoma treated with neoadjuvant chemoradiotherapy (neo-CRT) and total mesorectal excision. 210 patients with locally advanced rectal carcinoma (cT3-4 or cN+) treated with neo-CRT followed by total mesorectal excision. Treatment outcomes were compared according to clinical and pathological stage. Overall survival (OS), disease free survival (DFS) among patients with different clinical stage and pathological stage after neo-CRT. The median follow-up time was 47 months (range, 14–98 months). Clinical T stage was associated with 5 year OS (p = 0.042) and 5 year DFS (p = 0.014) while clinical N stage was not associated with 5 year OS (p = 0.440), 5 year DFS (p = 0.711). Pathological T stage was associate with 5 year OS (p = 0.001) and 5 year DFS (p = 0.046); and N stage was associated with 5 year OS (p = 0.001), 5 year DFS (p = 0.002). The pathological stage was further classified into three groups: ypT0–2N0 in 91 patients (43.3 %), ypT3–4N0 in 69 patients (32.9 %) and ypT0–4N+ in 50 patients (23.8 %). While pathological stage (ypT0–2 vs ypT3–4N0 vs ypT0–4N+) was associated with 5 year OS (87.9 %, 75.5 %, 56.7 %, p = 0.000), 5 year DFS (74.5 %, 77.4 %, 50.5 %, p = 0.003). Multivariate analysis showed that ypN stage was an independent prognostic factor for patients 5 year DFS. Pathological stage is strongly associated with treatment outcomes in patients with locally advanced rectal carcinoma treated with neo-CRT followed by total mesorectal excision, which may be used as guidance for further individualized treatment

    Lack of technetium-99m methoxyisobutylisonitrile ( 99m Tc-MIBI) uptake is consistently reported to predict poor response to subsequent chemotherapy in a variety of human malignant tumours. Since 99m Tc-MIBI accumulates within mitochondria, which also play a central role in apoptosis through the integration of death signals by Bcl-2 family members, we tested whether early 99m Tc-MIBI uptake is affected by alterations of the apoptotic pathway. Forty-two breast cancer patients were intravenously injected with 740 MBq of 99m Tc-MIBI and planar images were obtained 10 min post injection with the patients in the prone lateral position. Ten carcinomas failed to accumulate 99m Tc-MIBI and could not be visualised on scintigraphic images despite being larger than 1.8 cm (MIBI negative). Thirty-two of the 42 breast carcinomas showed focal uptake of 99m Tc-MIBI (MIBI positive), and 10 min tumour-to-background ratios (T/B) varied between 1.14 and 6.93. The apoptotic index, the rate of proliferation, and the expression of the anti-apoptotic Bcl-2 protein and pro-apoptotic Bax protein were assessed in surgically excised tumours. All MIBI-negative carcinomas showed a dramatic and statistically significant reduction in the apoptotic index as compared with MIBI-positive lesions (mean±SD, 0.14±0.15 vs 1.28±0.83, P 99m Tc-MIBI in breast carcinomas is affected by alterations of apoptotic pathway. High levels of Bcl-2, despite the stabilisation of mitochondrial membrane potentials, prevent accumulation of 99m Tc-MIBI in tumour cells. In conclusion, absent or reduced early 99m Tc-MIBI uptake in large tumours may indicate a Bcl-2-mediated resistance to chemo- and radiotherapy. (orig.)

    Lymphoepithelioma-like carcinoma (LELC) is a rare type of neoplasm in which only twenty cases have been reported in the breast. This type of tumor can be difficult to distinguish from other breast tumors particularly medullary carcinoma and lymphoma in the breast. We present a case of LELC of the breast presenting as an abscess along with a review of the literature. This is the 21(st) reported case of LELC of the breast and the first case to present as an abscess. Her clinical picture could have been mistaken for other infectious or inflammatory diseases. Given the potential for favorable outcome, early detection and general knowledge of this neoplasm are essential to expedite treatment for this rare tumor type.

    Conclusion: Cancer pain in patients with advanced hepatocellular carcinoma can be alleviated with electroacupuncture and multiple acupoint stimulation, but the onset pain relief was slow. To improve the analgesic effects of this technique, the combination of various analgesic methods should be necessary in early stage of the treatment.

    Purpose: In 1991, we started a clinical prospective trial for operable esophageal carcinoma, foreseeing organ preservation, to assess the treatment results after definitive chemoradiotherapy (Crt) for clinical Stage I (Taman) esophageal cancer. Patients and Methods: Between 1992 and 2003, 63 patients were enrolled in this study. Tumor depth was mucosal cancer (T 1a) in 23 and submucosal cancer (T 1b) in 40. Crt consisted of 55-66 Gy/50-60 fractions (median, 59.4 Gy); from 1 to 3 cycles (median, 2) of concurrent chemotherapy (Cisplatin and 5-fluorouracil), followed by high-dose-rate intraluminal brachytherapy 10-12 Gy/2-3 fractions. Results: The 5-year overall and cause-specific and disease-free survival rates were 66.4%, 76.3%, and 63.7%, respectively. The 5-year cause-specific survival rates for T 1a and T 1b cancer patients were 85.2% and 70.0%, respectively (p = 0.06). The 5-year disease-free survival rates for T 1a and T 1b were 84.4% and 50.5%, respectively (p < 0.01). Esophageal fistula as a late toxicity occurred in 2 patients (G: 1; G: 1), and esophageal stricture requiring a liquid diet occurred in 2 patients. Pericardial effusion was observed in 3 patients. Conclusion: We confirmed that patients with Taman esophageal carcinoma had their esophagus preserved in 89.2% of cases after definitive Crt, and the survival rates were equivalent to those of previous reports of surgery

    Full Text Available Abstract The Gorlin-Goltz syndrome, also known as nevoid basal cell carcinoma syndrome (NBCCS, is an infrequent multisystemic disease inherited in a dominant autosomal way, which shows a high level of penetrance and variable expressiveness. It is characterized by keratocystic odontogenic tumors (KCOT in the jaw, multiple basal cell nevi carcinomas and skeletal abnormities. This syndrome may be diagnosed early by a dentist by routine radiographic exams in the first decade of life, since the KCOTs are usually one of the first manifestations of the syndrome. This article paper reports the case of a patient, a 10-year-old boy with NBCCS, emphasizing its clinical and radiographic manifestations. This study highlights the importance of health professionals in the early diagnosis of NBCCS and in a preventive multidisciplinary approach to provide a better prognosis for the patient.

    Full Text Available The paper describes a clinical case of a local recurrence of tubulocystic carcinoma (TCC in a 46-year-old man, a relatively good course (the relapse occurred after 4 years, who has been successfully operated on and is being followed up. This disease is a rare renal malignancy and, until recently, it has been referred to as collecting tubular carcinoma. However, this disease has come to be regarded as an independent nosological entity, by taking into account its certain morphological, immunohistohemical, and cytogenetic characteristics, as well as the nature of its course. About 80 TCC cases have been described to date. Further study of this disease and other rare renal malignancies will allow the more accurate elaboration of management tactics for such patients in terms of certain prognostic factors, which calls for a larger number of cases of this disease.

    Hypoxia-inducible factor 1 (HIF-1) is a transcription factor, which plays a central role in biologic processes under hypoxic conditions, especially concerning tumour angiogenesis. HIF-1α is the relevant, oxygen-dependent subunit and its overexpression has been associated with a poor prognosis in a variety of malignant tumours. Therefore, HIF-1α expression in early stage oral carcinomas was evaluated in relation to established clinico-pathological features in order to determine its value as a prognostic marker. 85 patients with histologically proven surgically treated T1/2 squamous cell carcinoma (SCC) of the oral floor were eligible for the study. Tumor specimens were investigated by means of tissue micro arrays (TMAs) and immunohistochemistry for the expression of HIF-1. Correlations between clinical features and the expression of HIF-1 were evaluated by Kaplan-Meier curves, log-rank tests and multivariate Cox regression analysis. HIF-1α was frequently overexpressed in a probably non-hypoxia related fashion. The expression of HIF-1α was related with a significantly improved 5-year survival rate (p < 0.01) and a significantly increased disease free period (p = 0.01) independent from nodal status and tumour size. In primary node negative T1/T2 SCC of the oral floor, absence of HIF-1α expression specified a subgroup of high-risk patients (p < 0.05). HIF-1α overexpression is an indicator of favourable prognosis in T1 and T2 SCC of the oral floor. Node negative patients lacking HIF-1α expression may therefore be considered for adjuvant radiotherapy

    Ovarian carcinoma has been difficult to diagnose at an early stage. Recently, it has been recognized that the measurement of blood N-ERC/mesothelin levels aids early detection in and postoperative therapeutic monitoring of patients with mesothelioma, who have been exposed to asbestos. ERC/mesothelin has also been reported to be expressed in ovarian carcinoma. We determined serum N-ERC/mesothelin levels in patients with ovarian carcinoma using an enzyme-linked immunosorbent assay (ELISA). In addition, we immunohistochemically evaluated surgically resected specimens for C-ERC/mesothelin expression. As a result, of the 32 patients with ovarian tumors (18 carcinoma, 2 borderline tumors), one patient with serous adenocarcinoma showed increased N-ERC/ mesothelin levels. Immunohistochemically, of the 20 ovarian tumor (carcinoma and borderline tumor) specimens evaluated for serum N-ERC/mesothelin, 9 (45.0%) were positive for C-ERC/mesothelin. The C-ERC/mesothelin-positive specimens were found to be serous and clear cell adenocarcinomas. If serum N-ERC/mesothelin, which is considered useful for early detection in and therapeutic monitoring of patients with mesothelioma, may also be used for ovarian carcinoma monitoring, it may be a valuable serum tumor marker for the early detection of ovarian carcinoma.

    Full Text Available Introduction: Concurrent cisplatin-based chemoradiation is currently considered the treatment of choice for locoregional nasopharyngeal carcinoma. Celecoxib is a selective cyclooxygenase-2 (COX-2 inhibitor which can potentially enhance the effect of radiotherapy. The aim of this study was to determine the efficacy and safety of celecoxib in nasopharyngeal carcinoma. Materials and Methods: Patients with newly diagnosed locoregional nasopharyngeal carcinoma were included in this clinical trial study. The patients were assigned to receive 7 weeks concurrent chemoradiation with weekly cisplatin and either celecoxib 100 mg twice daily or placebo. After completion of chemoradiation, all patients received combined chemotherapy with cisplatin plus 5-Fu every 3 weeks for 3 cycles. Clinical response rates and treatment-related toxicity were the primary and secondary end-point of the study. Results: Total of 50 eligible patients with the median age of 43 years were enrolled in the trial. Overall (complete and partial clinical response rate was 100% in both groups. Complete and partial clinical response rates were 64% and 36% in study group and 44% and 56% in control group respectively (P>0.25. There was no difference in terms of treatment-related toxicity rates between two groups. Conclusions: This clinical trial showed that addition of celecoxib 100 mg twice daily to concurrent chemoradiation does not increase the response rates and treatment-related toxicities in patients with locoregional nasopharyngeal carcinoma.

    The purpose of this study was to analyse the usefulness of high resolution CT (HRCT) for the diagnosis and localization of roentgenographically occult lung cancer. HRCT was performed prospectively on chest X-ray negative patients with bloody sputum or suspicious or positive cells on sputum cytology between 1998 and 2000. After the HRCT scan, white light bronchoscopy and autofluorescence bronchoscopy were performed. HRCT depicted 19 hilar bronchial lesions in 13 cases out of 19 patients, of which 9 lesions were confirmed by white light broncoscope. Of 8 hilar squamous cell carcinomas diagnosed in this study, 7 lesions (87.5%) were depicted by HRCT. One CT-negative case (12.5%) was an in situ carcinoma in left B 1+2 . Four out of 20 lesions which showed bronchoscopic abnormality, could not be depicted by HRCT. HRCT could prospectively detect 80% of the bronchoscopic abnormalities and 87.5% of the hilar squamous cell carcinomas of the tracheobronchial lesions of the lung. Therefore, HRCT can be an effective supplemental means for screening for hilar squamous cell carcinoma. (author)

    Hepatocellular carcinoma (HCC) is one of the most aggressive tumors, and the treatment outcome of this disease is improved when the cancer is diagnosed at an early stage. This requires biomarkers allowing an accurate and early tumor diagnosis. To identify potential markers for such applications, we analyzed a patient cohort consisting of 50 patients (50 HCC and 50 adjacent nontumorous tissue samples as controls) using two independent proteomics approaches. We performed label-free discovery analysis on 19 HCC and corresponding tissue samples. The data were analyzed considering events known to take place in early events of HCC development, such as abnormal regulation of Wnt/b-catenin and activation of receptor tyrosine kinases (RTKs). 31 proteins were selected for verification experiments. For this analysis, the second set of the patient cohort (31 HCC and corresponding tissue samples) was analyzed using selected (multiple) reaction monitoring (SRM/MRM). We present the overexpression of ATP-dependent RNA helicase (DDX39), Fibulin-5 (FBLN5), myristoylated alanine-rich C-kinase substrate (MARCKS), and Serpin H1 (SERPINH1) in HCC for the first time. We demonstrate Versican core protein (VCAN) to be significantly associated with well differentiated and low-stage HCC. We revealed for the first time the evidence of VCAN as a potential biomarker for early-HCC diagnosis.

    To explore the clinical significance of combined detection of serum pepsinogen I(PG-I), carbohydrate antigen 72-4 (CA72-4) and tumor supplied group of factor(TSGF) in patients with gastric carcinoma, the serum PG-I, CA72-4 and TSGF in patients with gastric carcinoma, chronic superficial gastritis, chronic atrophic gastritis,gastric ulcer and normal controls were detected by immunoradiometric assay, electrochemluminescence immunoassay and biochemical colorimetry respectively. The results showed that the serum level of PG-I (36.76±10.16 ug/L) in patients with gastric carcinoma was remarkably lower than that in controls, and the serum levels of CA72-4 (5.92±2.53 U/ml) and TSGF (107±15.3 U/ml) in patients with gastric carcinoma were significantly higher than those in other groups. The positive rates of PG-I, CA72-4 and TSGF in patients with gastric carcinoma were 42.85%, 42.85% and 45.71% respectively. The positive rate of combined detection was 80%. The serum levels of PG-I, CA72-4 and TSGF are related to the biology behavior of gastric carcinoma. The detection of serum PG-I, CA72-4 and TSGF would help to judge the metastasis and prognosis of gastric carcinoma. The combined detection of the three marks could increase the diagnosis accuracy of gastric carcinoma. (authors)

    To investigate hepatocellular carcinoma screening utilisation and factors associated with utilisation among patients prescribed hepatitis B virus anti-viral therapy and at risk of hepatocellular carcinoma. The incidence of hepatocellular carcinoma has increased in Australia over the past three decades with chronic hepatitis B virus infection a major contributor. hepatocellular carcinoma surveillance programs aim to detect cancers early enabling curative treatment options, longer survival and longer times to recurrence. Multi-site cross-sectional survey. An online study questionnaire was administered to eligible participants attending three Sydney tertiary hospitals. Data were grouped into six mutually exclusive hepatocellular carcinoma risk factor categories as per American Association for the Study of Liver Diseases guidelines. All analyses were undertaken in STATA. Logistic regression was used to assess the associations between covariates and screening utilisation. Multivariate models described were assessed using the Hosmer-Lemeshow goodness of fit. Of the 177 participants, 137 (77.4%) self-reported that US had been performed in the last six months. Awareness that screening should be performed and knowing the correct frequency of US screening were independently associated with screening utilisation. Participants who knew that screening should be undertaken were three times more likely to have had pretreatment education or were prescribed hepatitis B virus anti-viral treatment for >4 years. Participants reporting a family history of hepatocellular carcinoma were less likely to know that screening should be undertaken every 6 months. While utilisation of hepatocellular carcinoma surveillance programs was higher in this study than in previous reports, strategies to further improve surveillance remain necessary. Findings from this research form the basis for proposing strategies to improve utilisation of hepatocellular carcinoma screening, inform hepatitis B virus

    The significance of various radiographic signs in 183 patients with clinically occult breast disease is described. 30.6% hat a carcinoma of the breast or a carcinoma in situ. The radiological features have varying predictive values and there is variation in the incidence of lymph node metastases. It is considered useful to classify the radiological appearances under the headings of round foci, star-shaped opacities, diffuse opacities, opacities with calcification and groups of micro-calcification. Despite the early diagnosis, 24% of patients already had lymph node metastases.

    2005-01-01

    Aim: For the examination of the impact on clinical practice of the guidelines for differentiated thyroid carcinoma (DTC), treatment data from the ongoing multicenter study differentiated thyroid carcinoma (MSDS) were analyzed. Patients, methods: patients were randomized to adjuvant external beam radiotherapy (RTx) or no RTx in addition to standard therapy in TNM stages pT4 pNO/1/x MO/x (UICC, 5 th ed. 1997). All patients were to receive the same treatment regimen consisting of thyroidectomy, ablative radioiodine therapy (RIT), and a diagnostic 131 I whole-body scintigraphy (WBS) 3-4 months after RIT. Results: Of 339 eligible patients enrolled between January 2000 and March 2004, 273 could be analyzed. Guideline recommendations by the German Society for Nuclear Medicine from 1999 and 1992 were complied with within 28% and 82% with regard to the interval between surgery and RIT (4 vs. 4-6 weeks), in 33% and 84% with regard to 131 I activity for RIT (1-3 vs. 1-4 GBq; ±10%), and in 16% and 60% with regard to 131 I activity for WBS (100-300 vs. 100-400 MBq; ±10%). Conclusions: the 1999 guideline revision appears to have had little impact on clinical practice. Further follow-up will reveal if guideline compliance had an effect on outcomes. (orig.)

    Full Text Available Abstract Background Bladder transitional cell carcinoma (BTCC is the fourth most frequent neoplasia in men, clinically characterized by high recurrent rates and poor prognosis. Availability of urinary tumor biomarkers represents a convenient alternative for early detection and disease surveillance because of its direct contact with the tumor and sample accessibility. Results We tested urine samples from healthy volunteers and patients with low malignant or aggressive BTCC to identify potential biomarkers for early detection of BTCC by two-dimensional electrophoresis (2-DE coupled with mass spectrometry (MS and bioinformatics analysis. We observed increased expression of five proteins, including fibrinogen (Fb, lactate dehydrogenase B (LDHB, apolipoprotein-A1 (Apo-A1, clusterin (CLU and haptoglobin (Hp, which were increased in urine samples of patients with low malignant or aggressive bladder cancer. Further analysis of urine samples of aggressive BTCC showed significant increase in Apo-A1 expression compared to low malignant BTCC. Apo-A1 level was measured quantitatively using enzyme-linked immunosorbent assay (ELISA and was suggested to provide diagnostic utility to distinguish patients with bladder cancer from controls at 18.22 ng/ml, and distinguish patients with low malignant BTCC from patients with aggressive BTCC in two-tie grading system at 29.86 ng/ml respectively. Further validation assay showed that Apo-A1 could be used as a biomarker to diagnosis BTCC with a sensitivity and specificity of 91.6% and 85.7% respectively, and classify BTCC in two-tie grading system with a sensitivity and specificity of 83.7% and 89.7% respectively. Conclusion Taken together, our findings suggest Apo-A1 could be a potential biomarker related with early diagnosis and classification in two-tie grading system for bladder cancer.

    Male breast carcinomas are rare tumours, accounting for less than 1% of all malignancies in men. Intracystic Papillary Carcinoma (IPC) in males is a very rare entity, representing 5-7.5% of all male breast carcinomas. It lacks the classical clinical, radiological and cytological features of malignancy and usually presents as a benign-appearing lump. We report a case of Infiltrating Ductal Carcinoma (IDC) co-existing with intracystic papillary carcinoma in a 53-year-old male who presented with lump in the right breast.

    Full Text Available Introduction. The incidence of gallbladder cancer presenting with acute cholecystitis is 2.3%, squamous cell carcinoma is rarely seen, and overlap of acute cholecystitis and squamous cell carcinoma is a very rare condition in the literature. Presentation of Case. A 75-year-old woman was admitted to emergency service with a pain in the right upper quadrant, nausea, and vomiting. The patient was considered as having acute cholecystitis. During the exploration because Hartman’s pouch was not dissected, it was adhered to the cystic duct and had fibrotic adhesion. It could not be understood whether this adhesion was a tumor or a fibrotic tumor and thus we performed cholecystectomy with a 1 cm resection of the choledochus. Pathological examination revealed the presence of (R0, T1 N0 M0 squamous cell carcinoma with clean resection borders and there was no in tumor five dissected lymph nodes. The patient has been followed up for about two years and no clinical problem has been observed throughout the follow-up. Discussion. Acute cholecystitis with gallstones may overlap with gallbladder cancer and generally presents nonspecific symptoms. No additional imaging techniques were performed since no clinical sign except for the wall thickening was detected and no suspected malignancy such as mass was detected on USG. Squamous cell carcinoma of the gallbladder shows poor diagnosis, but since its overlap with cholecystitis presents early symptoms and thus leads to early diagnosis and effective treatment, the localization of the carcinoma is of prime importance. Conclusion. Gallbladder cancer should be kept in mind in elderly patients with acute cholecystitis.

    Full Text Available Introduction: The epidermoid carcinoma of the upper aerodigestive tract is diagnosed in approximately 40% of the cases of advanced clinical stages. Objective: To evaluate the disease-free interval in patients with clinical stages I and II epidermoid carcinoma who were submitted to surgery or chemoradiation. Method: Retrospective study of the records of 139 patients treated for oropharyngeal epidermoid carcinoma submitted to treatment with curative intent. Among those patients, 38 were classified with early tumors clinical stages I and II. Twenty-seven (71.1% underwent surgical treatment whereas eleven (28.9% were treated with chemoradiation. The mean age was 56.4 years; 31 cases (81.6% were in men and seven (18.4% were in women. Results: Among the eleven patients who were submitted to chemoradiation, 72.7% obtained locoregional control of the disease and their disease-free survival was of 42%. Among the 27 patients operated, 19 remained in Clinical Stages I and II in the histological report and six underwent postoperative radiation therapy. The disease-free interval for two years was of 70%. Conclusion: The patients submitted to the surgery had a better disease-free interval as compared to those submitted to chemoradiation treatment.

    Full Text Available The stem cell factor (SCF receptor CD117 (c-kit, is widely used for identification of hematopoietic stem cells and cancer stem cells. Moreover, CD117 expression in carcinoma cells indicates a poor prognosis in a variety of cancers. However the potential expression in tumor microenvironment and the biological and clinical impact are currently not reported. The expression of CD117 was immunohistochemically evaluated in a serial of 242 epithelial ovarian cancer (EOC cases. Thirty-eight out of 242 cases were CD117 positive in fibroblast-like stromal cells and 22 cases were positive in EOC cells. Four cases were both positive in fibroblast-like stromal cells and EOC cells for CD117. CD117 expression in fibroblast-like stromal cells in ovarian carcinoma was closely linked to advanced FIGO stage, poor differentiation grade and histological subtype (p<0.05, and it was significantly associated with poor overall survival (OS and progression free survival (PFS (Kaplan-Meier analysis; p<0.05, log-rank test. CD117 expression in ovarian carcinoma cells was not associated with these clinicopathological variables. The CD117 positive fibroblast-like stromal cells were all positive for mesenchymal stem/stromal cell (MSC marker CD73 but negative for fibroblast markers fibroblast activation protein (FAP and α smooth muscle actin (α-SMA, indicating that the CD117+/CD73+ fibroblast-like stromal cells are a subtype of mesenchymal stem cells in tumor stroma, although further characterization of these cells are needed. It is concluded herewith that the presence of CD117+/CD73+ fibroblast-like stromal cells in ovarian carcinoma is an unfavorable clinical outcome indication.

    Objective: To investigate the value of 18 F-FDG coincidence imaging for diagnosis of nasopharyngeal carcinoma. Methods: A total of 45 patients with nasopharyngeal carcinoma (33 males and 12 females, average age (55.56 ± 13.50) years), who underwent 18 F-FDG coincidence imaging before treatment, were studied retrospectively. The images of 18 F-FDG coincidence imaging (GE Millennium VG SPECT) and MRI were analyzed. The radioactivity ratio of the accumulated regions to cerebellum (T/NT)was calculated by ROI technique. The volume of nasopharyngeal carcinoma was recorded by MRI. The positive rates of 18 F-FDG coincidence imaging and EB virus-related antibody measurements were compared by paired χ 2 test. The correlation between T/NT ratios and tumor volumes were tested by Pearson correlation, and then ROC curves were established. The T/NT ratios and tumor volumes of different groups (different first symptoms, clinical stages, T stages, pathological classification and outcomes, with or without lymph node enlargement) were compared by t-test and rank sum test. Results: The positive rate of 18 F-FDG coincidence imaging was 97.78% (44/45), and the positive rate of EB virus-related antibody measurement was 95.56% (43/45, χ 2 =1.33, P>0.05). The T/NT ratio (2.439 ±1.119) and tumor volume ((7.311 ± 8.280) cm 3 ) of primary lesions had a positive correlation (r=0.463, P<0.05). The cut-off values of T/NT ratio and the tumor volume were 2.396 and 7.348 cm 3 , respectively, by ROC curves. T/NT ratios in groups with or without first symptom of epistaxis (2.847 ± 1.254 vs 2.082 ± 0.863, t=-2.409) and groups with or without facial numbness (2.855 ± 1.261 vs 2.134 ± 0.913, t=-2.225) were both significantly different (both P<0.05). T/NT ratios of differentiated and undifferentiated cancer were 2.266 ± 0.997 and 2.971 ± 1.351, respectively (t=-2.018, P<0.05). There was a significant difference of tumor volumes between groups with or without facial numbness (t=-2.684, P<0

    Tumors can metastasize to the oral cavity and affect the jaws, soft tissue and salivary glands. Oral cavity metastases are considered rare and represent approximately 1% of all oral malignancies. Because of their rarity and atypical clinical and radiographic appearance, metastatic lesions are considered a diagnostic challenge. The purpose of this report is to present a rare case of a metastatic breast carcinoma mimicking a periodontal abscess in the mandible. A 55-year-old Caucasian woman was referred to our clinic for evaluation of bisphosphonate-induced jaw osteonecrosis. She had undergone modified radical mastectomy with axillary lymph node dissection for invasive ductal carcinoma of the left breast. Her clinical examination showed diffuse swelling and a periodontal pocket of 6 mm exhibiting suppuration in the posterior right mandible. Moreover, paresthesia of the lower right lip and chin was noted. There were no significant radiographic findings other than alveolar bone loss due to her periodontal disease. Although the lesion resembled a periodontal abscess, metastatic carcinoma of the breast was suspected on the basis of the patient's medical history. The area was biopsied, and histological analysis confirmed the final diagnosis of metastatic breast carcinoma. The general dentist or dental specialist should maintain a high level of suspicion while evaluating patients with a history of cancer. Paresthesias of the lower lip and the chin should be considered ominous signs of metastatic disease. This case highlights the importance of the value of a detailed medical history and thorough clinical examination for the early detection of metastatic tumors in the oral cavity.

  4. Recurrent Syncope due to Esophageal Squamous Cell Carcinoma

    2011-09-01

    Full Text Available Syncope is caused by a wide variety of disorders. Recurrent syncope as a complication of malignancy is uncommon and may be difficult to diagnose and to treat. Primary neck carcinoma or metastases spreading in parapharyngeal and carotid spaces can involve the internal carotid artery and cause neurally mediated syncope with a clinical presentation like carotid sinus syndrome. We report the case of a 76-year-old man who suffered from recurrent syncope due to invasion of the right carotid sinus by metastases of a carcinoma of the esophagus, successfully treated by radiotherapy. In such cases, surgery, chemotherapy or radiotherapy can be performed. Because syncope may be an early sign of neck or cervical cancer, the diagnostic approach of syncope in patients with a past history of cancer should include the possibility of neck tumor recurrence or metastasis and an oncologic workout should be considered.

    Purpose. -- The objective of this retrospective study was to discuss the epidemio-clinical criteria and the therapeutic results of metastatic nasopharyngeal carcinoma. Patients and methods. - The current study concerned 95 patients with histologically proven nasopharyngeal carcinoma who were metastatic at diagnosis or who had developed late metastasis. We reviewed the epidemio-clinical records of all the patients. Patients were treated with chemotherapy (BEC regimen: bleomycin, epirubicin and cisplatin or PBF regimen: bleomycin, 5-fluorouracil and cisplatin) and radiotherapy of pauci metastatic localizations (single or double) or bone metastasis with high risk of compression or fracture ±associated with locoregional radiotherapy for patients who were metastatic at diagnosis. Response was assessed according to the WHO criteria. Overall survival was calculated according to the Kaplan-Meier method. A long-term disease-free survival was defined from 36 months. Results. - There were 34 patients who were metastatic at diagnosis and 61 patients who had developed late metastasis. The mean age was 41.5 years (sex-ratio: 3.1). Bone metastases were the most frequent (83%). Objective and complete response rates were respectively 75% and 70%, and 32% and 16% for BEC and PBF regimens. Twenty-five patients received radiotherapy for pauci metastatic localizations, among whom 19 patients who were metastatic at diagnosis received locoregional irradiation. The overall survival probability was of 15% for three years. Eleven patients were long survivors (extremes: 36 and 134 months). Conclusion. - Therapeutic results were comparable to those reported in other series using platin combination chemotherapy. Radiotherapy of metastasis yielded to long-term survival. (authors)

    Full Text Available Abstract Patients with ESCC (squamous cell carcinoma of the esophagus are most commonly diagnosed with locally advanced tumor stages. Early metastatic disease and late diagnosis are common reasons responsible for this tumor's poor clinical outcome. The prognosis of esophageal cancer is very poor because patients usually do not have symptoms in early disease stages. Squamous cell carcinoma of the esophagus frequently complicates patients with multiple co-morbidities and these patients often require interdisciplinary diagnosis and treatment procedures. At present time, neoadjuvant radiation therapy and chemotherapy followed by surgery are regarded as the international standard of care. Meta-analyses have confirmed that this approach provides the patient with better local tumor control and an increased overall survival rate. It is recommended that patients with positive tumor response to neoadjuvant therapy and who are poor surgical candidates should consider definitive radiochemotherapy without surgery as a treatment option. In future, EGFR antibodies may also be administered to patients during therapy to improve the current treatment effectiveness. Positron-emission tomography proves to be an early response-imaging tool used to evaluate the effect of the neoadjuvant therapy and could be used as a predictive factor for the survival rate in ESCC. The percentage proportions of residual tumor cells in the histopathological analyses represent a gold standard for evaluating the response rate to radiochemotherapy. In the future, early response evaluation and molecular biological tests could be important diagnostic tools in influencing the treatment decisions of ESCC patients.

    The relationship between the apoptosis and the expression of proliferating cell nuclear antigen (PCNA) and the clinical stages in gastric cancers was studied. By using terminal deoxynucleotidyl transferase-mediated nick end labeling (TUNEL) technique and PCNA immunohistochemical staining, the apoptosis and the expression of PCNA in tissue of gastric carcinoma were assayed in situ, the index of apoptosis (AI), index of PCNA (PI) and the rate of AI/PI were calculated. AI and PI in gastric cancer tissues were (6.5 +/- 3.7)% and (49.8 +/- 15.9)% respectively, and the rate of AI/PI was 0.13 +/- 0.05, which were obviously different from those of normal gastric mucosa in paragastric cancer (P stages of gastric carcinoma, the AI was decreased, PI was increased and the rate of AI/PI decreased in gastric carcinoma. There was significant difference in them between the gastric cancer tissues and normal gastric mucosa in pericarcinoma in TNM stage II to IV (P gastric carcinoma. The AI, PI and the rate of AI/PI would become the prognostic factors in advanced gastric carcinoma.

    Canine inflammatory mammary carcinoma (IMC) is a rare, locally aggressive, highly metastatic tumor that is poorly responsive to treatment. The purposes of this study were to retrospectively evaluate the history, signalment, and clinical signs of dogs with IMC; compare the outcome of affected dogs treated with traditional chemotherapy with those treated with piroxicam; evaluate Cox-2 expression of IMC cells; and correlate Cox-2 expression with outcome based on treatment. Strong cyclooxygenase-2 expression was present in all tumors. Improvement in clinical condition and disease stability was achieved in all dogs treated with piroxicam, with mean and median progression-free survival of 171 and 183 days, respectively. Median survival time of 3 dogs treated with doxorubicin-based protocols was 7 days, which was significantly less than that of dogs treated with piroxicam (median, 185 days). In conclusion, piroxicam should be considered as a single agent for the treatment of dogs with inflammatory mammary carcinoma. PMID:19436636

    Hürthle cell carcinoma (HCC) is an uncommon thyroid cancer historically considered to be a variant of follicular thyroid carcinoma (FTC). The aim of this study was to assess the differences between these groups in terms of clinical factors and prognoses. A total of 230 patients (153 with FTC and 77 with HCC) with a median follow-up of 13.4 years were studied. The different characteristics were compared using SPSS version 20 statistical software. Patients with HCC were older (57.3±13.8 years vs. 44.6±15.2 years; P<.001). More advanced TNM stages were also seen in patients with HCC and a greater trend to distant metastases were also seen in patients with HCC (7.8% vs. 2.7%, P=.078). The persistence/recurrence rate at the end of follow-up was higher in patients with HCC (13% vs. 3.9%, P=.011). However, in a multivariate analysis, only age (hazard ratio [HR] 1.10, confidence interval [CI] 1.04-1.17; P=.001), size (HR 1.43, CI 1.05-1.94; P=.021), and histological subtype (HR 9.79, CI 2.35-40.81; P=.002), but not presence of HCC, were significantly associated to prognosis. HCC is diagnosed in older patients and in more advanced stages as compared to FTC. However, when age, size, and histological subtype are similar, disease-free survival is also similar in both groups.

    The principle of the therapy of carcinoma cervicis uteri in the Research Institute of Clinical and Experimental Oncology in Brno is the combination of betatron megavoltage irradiation and cobalt 60 irradiation with intracavital radium irradiation. On the basis of many years' study concerning the therapy and therapeutic results of this tumor accurate directions of total therapy were elaborated. Carcinoma is diagnosed and classified precisely according to valid international directions. In addition to basic examination, limb lymphography was introduced giving the strategy of irradiation when lymphatic system is involved and in early stages of the disease. By preliminary evaluation of the obtained data a certain improvement of therapeutic results is proven. About 15% more patients are alive till 5 years without any signs of the disease than in precedent years. In spite of a high dose summation given by the extent of megavoltage irradiation the number of postirradiation reaction, nor early late, is increased to much. Complex therapy of this tumor is performed by a team of physicians composed of gynecologist, radiologist, rentgendiagnosticist, pathologist, and radiation physicist. By increasing the number of cured patients and their return and enclosure into further working process the savings in state budget are achieved. The effectiveness of the carcinoma cervicis uteri therapy is therefore dependent not only on earlier diagnosis and modern irradiation technique, but also on the cooperation of a team of physicians who plan, perform and follow the therapy.

    Full Text Available Abstract Background Oncocytic carcinoma is an extremely rare neoplasm of the salivary glands. We report a case of oncocytic carcinoma arising in a parotid gland in a 66-year-old female. Method An excisional biopsy of the parotid tumor was performed. The specimen was submitted for histology and after fixation in formalin solution and inclusion in paraffin, 3–5 μm sections were stained with hematoxylin and eosin for conventional evaluation and Periodic acid Schiff stain. Immunohistochemical studies were performed using antibodies against mitochondrial antigen, keratin, S-100, alpha-actin, vimentin, alpha-1-antichymotrypsin as well as an ultrastructural analysis was performed. Results Frozen sections revealed an infiltrative growth pattern and the diagnosis of a malignant epithelial lesion was made. Permanent sections stained with haematoxylin and eosin revealed a neoplasm that had replaced a wide area of the parotid gland and had invaded subcutaneous adipose tissue. Perineural invasion was evident, but vascular invasion was not found. Neoplastic elements were large, round or polyhedral cells and were arranged in solid sheets, islands and cords. The cytoplasm was abundant, eosinophilic and finely granular. The nuclei were large and located centrally or peripherally. The nucleoli were distinct and large. Periodic acid Schiff stain demonstrated a granular cytoplasm. Immunohistochemistry demonstrated mithochondrial antigen, keratin, and chymotrypsin immunoreactivity in the neoplastic cells. Ultrastructural analysis revealed numerous mitochondria packed into the cytoplasm of the neoplastic cells. Thus, the final diagnosis was that of oncocytic carcinoma of parotid gland. Conclusion This neoplasm shows clinical, microscopical, histological and ultrastructural features of oncocytic carcinoma and this must be considered in the differential diagnosis of other proliferations in the parotid gland with abundant granular cytoplasm and metastatic oncocytic

    Full Text Available Pure myoepithelioma of breast is an extremely rare tumor. Only a few cases have been reported in the literature so far. A 30-year old female presented with a large fungating mass arising from the areolar region of her right breast of six months duration. A clinical diagnosis of breast carcinoma was made and a mastectomy was performed. The specimen measured 23x22x9 cm with attached skin, and showed a large white ulcerated growth with areas of necrosis and hemorrhage. No normal breast tissue, nipple or areolar region was seen. Histopathological examination showed oval to spindle cells arranged in fascicles and bundles with whorling pattern in places showing mild pleomorphism with oval to spindle-shaped vesicular nuclei, prominent eosinophilic nucleoli, eosinophilic cytoplasm and clear cell changes in places, along with perivascular hyalinization and collagenization. Differential diagnosis of pleomorphic hyalinizing angiectatic tumor, solitary fibrous tumor, perivascular epithelioid cell tumor, mammary type myofibroblastic tumor and myoepitheliomawereallconsidered.Immunohistochemistry for vimentin, smooth muscle actin, calponin, caldesmon, p63, epithelial membrane antigen, S-100, CD-31, CD-34, muscle specific antigen, myogenin, desmin, and pancytokeratin was carried out. On the basis of positive staining for vimentin, actin, p63 (nuclear, calponin and caldesmon (focal, a final diagnosis of myoepithelioma was considered; however, cytokeratin negativity was an unusual finding. This case was considered worthy of documentation because of its rarity, and because it highlights the importance of proper clinical examination and radiological examination to prevent misdiagnosis.

    To evaluate the long-term results of exclusive chemotherapy for T1-T3N0M0 glottic squamous cell carcinoma complete clinical responders after induction chemotherapy. Between 1985 and 2000, 69 patients with glottic squamous cell carcinoma complete clinical responders after induction chemotherapy were managed with exclusive chemotherapy at our department. Chemotherapy associated platinum and fluorouracil. This retrospective analysis evaluated actuarial survival, treatment morbidity, oncologic events and laryngeal preservation. Various independent factors were tested for potential correlation with survival and local recurrence. The 5-year Kaplan-Meier actuarial survival, local control, lymph node control estimate were 83,6%, 64,8%, 98,6% respectively. Chemotherapy never resulted in death. The 10-year actuarial metachronous second primary tumors estimate was 32%. The overall laryngeal preservation rate was 98,6%. Altogether our data and the review of the literature suggest that in patients achieving a complete clinical response after and induction based chemotherapy regimen, the completion of an exclusive chemotherapy regimen appears to be a valid alternative to the conventional use of radiotherapy or chemo-radiation protocols.

    Pulmonary sarcomatoid carcinomas are a rare group of tumors accounting for about one percent of non-small cell lung carcinoma (NSCLC). In 2015, the World Health Organization classification united under this name all the carcinomas with sarcomatous-like component with spindle cell or giant cell appearance, or associated with a sarcomatous component sometimes heterologous. There are five subtypes: pleomorphic carcinoma, spindle cell carcinoma, giant cell carcinoma, carcinosarcoma and pulmonary blastoma. Clinical characteristics are not specific from the other subtypes of NSCLC. Epithelial to mesenchymal transition pathway may play a key role. Patients, usually tobacco smokers, are frequently symptomatic. Tumors are voluminous more often peripherical than central, with strong fixation on FDG TEP CT. Distant metastases are frequent with atypical visceral locations. These tumors have poorer prognosis than the other NSCLC subtypes because of great aggressivity, and frequent chemoresistance. Here we present pathological description and a review of literature with molecular features in order to better describe these tumors and perhaps introduce new therapeutics. Copyright © 2016.

    Full Text Available Abstract Background Current imaging techniques provide only limited information pertaining to the extent of infiltration of laryngeal carcinomas into vocal fold tissue layers. Therefore, it is needed to seek the contribute to the body of knowledge surrounding examination and characterization in laryngeal carcinoma infiltration. Methods Excised larynges were collected from 30 male laryngectomy patients with an average age of 43.5 years (ranging 36 to 55 years and history of smoking (≥10 years exhibiting T1, T2, or subglottal (normal vocal fold carcinomas. Vocal folds were preserved via freezing or immersion in paraffin. The depth of the mucosa, submucosa, and muscular layers in both normal vocal folds and tumor tissues of afflicted vocal folds was measured. Results The average depths of the mucosa, submucosa, and muscular layers in normal vocal folds were 0.15 ± 0.06 mm, 2.30 ± 0.59 mm, and 2.87 ± 0.88 mm, respectively. Infiltration measurements of T1 tumors showed a depth of 1.62 ± 0.51 mm and 1.32 ± 0.49 mm in frozen sections and paraffin-embedded samples, respectively. Similarly, T2 tumors showed a depth of 2.87 ± 0.68 mm and 2.58 ± 0.67 mm in frozen sections and paraffin-embedded samples, respectively. T1 and T2 tumors occupied 24.8 ± 10 and 48.5 ± 15 percent of the normal vocal fold depth, respectively. Conclusion This data provides a baseline for estimating infiltration of laryngeal carcinomas in vocal fold tissue layers, of particular interest to surgeons. This information may be used to assess typical depths of infiltration, thus allowing for more appropriate selection of surgical procedures based on individual patient assessment.

    Ovarian carcinoma represents about 4% of all cancers diagnosed in women worldwide. Mortality rate is high, over 50%, mainly due to late diagnosis. Currently there are no acceptable screening techniques available, although ovarian cancer belongs to the group of malignancies for which mortality could be dramatically reduced by early diagnosis. In a recently published study, we clearly demonstrated that human ovarian carcinoma tissues can be characterized by a specific odour, detectable by a trained dog. Another recent study confirmed these results using an electronic nose. In the present work, we examined whether the cancer-specific odour can also be found in the blood. Two specially trained dogs were used. Both ovarian cancer tissues and blood from patients with ovarian carcinoma were tested. The tissue tests showed sensitivity of 100% and specificity of 95%, while the blood tests showed sensitivity of 100% and specificity of 98%. The present study strongly suggests that the characteristic odour emitted by ovarian cancer samples is also present in blood (plasma) taken from patients with the disease. This finding opens possibilities for future screening of healthy populations for early diagnosis of ovarian carcinoma. A future challenge is to develop a sensitive electronic nose for screening of ovarian carcinoma by testing the blood/plasma to detect the disease at a stage early enough for treatment to be effective

    To evaluate local disease control and early complications of concomitant brachytherapy with external beam-radiotherapy in early stage carcinoma cervix. Fifty patients of early stage carcinoma cervix (FIGO-IB/IIA) were randomly divided into study group concomitant external beam irradiation (EBRT) and HDR-ICBT (intra-cavitary brachytherapy, xrt = 50 Gy/25 Fr, HDR 5.2 Gy*5 Fr) and the control group EBRT followed by HDR-ICBT (xrt = 50 Gy/25 Fr, HDR 7.5 Gy*3 Fr). Acute reactions and local disease response were compared between treatment and at 6-month follow up. Median overall treatment times were 38 and 61 days in the study and the control groups, respectively. Acute skin reactions and diarrhea were more in the study but manageable. At the completion of the study, there were 80 and 68 % complete responses, 16 and 20 % partial responses, 0 and 8 % stable diseases in the study group and the control group, respectively. Response was better in the study group but statistically insignificant. Larger number of patients and longer follow up are required to arrive at concrete conclusion.

    The purpose of this study was to assess the accuracy of contrast-enhanced magnetic resonance imaging (dynamic MR imaging) in the evaluation of preinvasive and early invasive cancer of the cervix. Twenty-nine women with untreated squamous cell carcinoma of the cervix with either no stromal invasion or early stromal invasion underwent pretreatment MR imaging and dynamic MR imaging within 4 weeks of surgical evaluation. The images were evaluated for tumor detection and compared with results of histologic examination of the surgical specimens. The lesions in 17 cases with histologically proven stromal invasion of 4 mm or greater were detected with dynamic MR imaging, whereas lesions in only 8 of these cases were detected with T2 imaging. In 9 cases with stromal invasion between 4.0 mm and 5.0 mm, lesions were represented as early phase focal enhancement on dynamic MR images, but not detected on T2-weighted images. In the 12 cases with less than 4 mm stromal invasion, no lesions were visualized on either T2-weighted images or dynamic MR images, except in 1 case of glandular involvement without stromal invasion that appeared as enhancement on early-phase dynamic MR imaging. Dynamic MR imaging detected more lesions of early stromal invasion in pretreatment imaging for cervical cancer than nonenhanced MR imaging. (author)

    This case report presents an incident of rectal carcinoma in a 24-year-old man with Hirschsprung's disease, for which he was operated in his early childhood, with a Soave pull-through procedure. No direct association between Hirschsprung's disease and rectal cancer was found in our review of the literature. However, several case reports of rectal cancers following pull-through procedures exist. A low threshold for further clinical investigations is recommended, if these patients are presenting with gastrointestinal symptoms.

    This study assessed the prognostic values of volumetric parameters on {sup 18}F-fluorodeoxyglucose (FDG) positron emission tomography (PET) in predicting early intrahepatic recurrence-free survival (RFS) after curative resection in patients with hepatocellular carcinoma (HCC). A retrospective analysis was performed on 242 patients with HCC who underwent staging FDG PET and subsequent curative surgical resection. The tumor-to-non-tumorous liver uptake ratio, metabolic tumor volume (MTV), and total lesion glycolysis (TLG) of the HCC lesions on PET were measured. The prognostic values of clinical factors and PET parameters for predicting overall RFS, overall survival (OS), extrahepatic RFS, and early and late intrahepatic RFS were assessed. The median follow-up period was 54.7 months, during which 110 patients (45.5%) experienced HCC recurrence and 62 (25.6%) died. Patients with extrahepatic and early intrahepatic recurrence showed worse OS than did those with no recurrence or late intrahepatic recurrence (p < 0.001). Serum bilirubin level, MTV, and TLG were independent prognostic factors for overall RFS and OS (p < 0.05). Only MTV and TLG were prognostic for extrahepatic RFS (p < 0.05). Serum alpha-fetoprotein and bilirubin levels, MTV, and TLG were prognostic for early intrahepatic RFS (p < 0.05) and hepatitis C virus (HCV) positivity and serum albumin level were independently prognostic for late intrahepatic RFS (p < 0.05). Intrahepatic recurrence showed different prognoses according to the time interval of recurrence in which early recurrence had as poor survival as extrahepatic recurrence. MTV and TLG on initial staging PET were significant independent factors for predicting early intrahepatic and extrahepatic RFS in patients with HCC after curative resection. Only HCV positivity and serum albumin level were significant for late intrahepatic RFS, which is mainly attributable to the de novo formation of new primary HCC. (orig.)

    The present study aimed to assess early-stage nasopharyngeal carcinoma (NPC) with dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) and diffusion-weighted imaging (DWI) at 3.0 T. A total of 44 patients newly diagnosed with NPC were included in the present study. All patients underwent MR examination at 3.0 T using DCE-MRI and DWI. The volume transfer constant ( K trans ), flux rate constant between extravascular extracellular space and plasma ( K ep ), the volume of extravascular extracellular space per unit volume of tissue ( V e ) and the apparent diffusion coefficient (ADC) of tumours were investigated. Furthermore, the correlation between clinical stages and ADC value and K trans were analysed. The diagnostic accuracy of K trans and ADC were estimated using receiver operating characteristic curves. NPC stage correlated positively with K trans and negatively with ADC values. Additionally, tumour K trans negatively correlated with ADC value. The sensitivity and accuracy of combined K trans and ADC in distinguishing between stage II and stage III and stage III and IV were higher than the values of either measurement used separately. The present study suggested that K trans and ADC derived from DCE-MRI and DWI may be useful to detect stage early NPC accurately. K trans and ADC in combination were superior than either alone.

    Basal cell carcinoma is the most common skin cancer, characterised by a slow growing behavior, metastasis are extremely rare, and it occurs in less than 0, 1% of all cases. Giant basal cell carcinoma is a rare form of basal cell carcinoma, more aggressive and defined as a tumor measuring more than 5 cm at its largest diameter. Only 1% of all basal cell carcinoma develops to a giant basal cell carcinoma, resulting of patient's negligence. Giant basal cell carcinoma is associated with higher potential of metastasis and even death, compared to ordinary basal cell carcinoma. We report a case of giant basal cell carcinoma metastaticin lung occurring in a 79 years old male patient, with a fatal evolution after one course of systemic chemotherapy. Giant basal cell carcinoma is a very rare entity, early detection of these tumors could prevent metastasis occurrence and improve the prognosis of this malignancy.

    To compare the efficacy of carbon dioxide (CO(2)) laser with cutting diathermy as a cutting device in surgical excision of early carcinoma tongue. Experimental study. Combined Military Hospital (CMH), Rawalpindi and CMH, Lahore, from July 2008 to July 2011. Twenty two biopsy proven cases of T(1) and early T(2) squamous cell carcinoma of tongue were divided in two equal groups of 11 each labeled as A and B. Tumor was excised by CO(2) laser in group A while cutting diathermy was done in group B. For both groups tumor excision time, per-operative blood loss, postoperative oral swelling and pain was recorded. Excision time of tumor was assessed in minutes and amount of blood loss in milliliters till complete hemostasis after removal of primary tumor. Postoperatively patients were assessed on 12 hourly basis for 48 hours for pain. Pain was analyzed on visual analogue score 1 - 10. Oral swelling was assessed once after 24 hours and labeled as mild, moderate and severe. Independent sample t-test was applied for analysis of excision time, postoperative pain and per-operative blood loss for both groups. Postoperative swelling was analyzed using Fisher's exact test. P-value of < 0.05 was considered significant. The mean age at diagnosis in group A was 49.36 ± 5.27 years, while in group B patients had mean age of 50.73 ± 8.13 years. In group A, 4/11 (36.3%) patients were having tumor stage T(1) while 7/11 (63.6%) had T(2) stage tumor. In group B, 5/11 (45.4%) were having T1 and 6/11 (54.5%) were having stage T(2) tumor. Excision time was significantly shorter for group B (p=0.003), but group A had less postoperative pain (p=0.001), less per-operative blood loss (p=0.001) and less postoperative oral swelling (p=0.021). Early carcinoma tongue is better removed by laser than electrocautery in terms of postoperative morbidity, per-operative blood loss, postoperative pain and oral swelling.

    Full Text Available Although genito-urinary tuberculosis is common, reports of isolated ovarian tubercular abscess are rare. Ovarian tubercular abscess may mimics that of an ovarian tumor, leading to diagnostic difficulties. We reported a case report of 35 years woman presented with chronic pain abdomen, weight loss, low-grade fever and a right ovarian mass on ultrasound, with a significantly elevated CA-125 level. On clinical and radiological evidence, diagnosis of ovarian carcinoma was made, and laparotomy was performed with resection of the ovary. Postoperative specimen sent for histological examination that revealed classic epithelioid granuloma and acid-fast bacilli were present in Ziehl-Neelsen stain. Patient was put on antitubercular regimen from our Dots center. She is improving clinical after taking antitubercular drug and is on regular follow up at our chest outpatient department. Ovarian tubercular abscess is common in young women living in endemic zones, but case report of isolated tubercular abscess is rarely reported. CA-125 can be raised in both ovarian tubercular abscess and ovarian carcinoma, and only imaging is not always conclusive. Laparotomy followed by tissue diagnosis can be helpful in this situation. As the prognosis and treatment outcome of ovarian tubercular abscess and ovarian carcinoma is different, proper diagnosis by laparotomy should be done. Early diagnosis of ovarian tubercular abscess is vital as untreated disease can lead to infertility.

    ório histopatológico.BACKGROUND: A retrospective and anatomopathological study was performed on 704 basal carcinomas of 623 patients, diagnosed from 1991 to 1996, at the Dermatopathology section of the Dermatology Clinic of the Hospital das Clinicas, UFPE and at a private dermatopathology laboratory in the city of Recife. OBJECTIVE: To characterize the clinical and anatomopathological aspects of the basal cell carcinomas diagnosed by the two services of Pernambuco region. METHODS: For the clinical study, the data were collected from the patient files and for the anatomopathological, macro and microscopic study a revision was made of the histological specimens. For determination of vertical growth, methods were used based on Clark and Breslow's histoprognostic techniques applied to malignant melanoma. RESULTS: Clinical: the highest incidence was in the feminine sex (55.7% and in the 55 to 72-year-old age group. Disease duration was highly variable, ranging from one month to 40 years, and the head was the most frequent topographical area (73.8%, mainly nasal (21.1% and zygomatic (18.5%. The nodular pigmented form (47.4% was found most frequently and the size of the lesions did not depend on the disease duration. Histologically the patterns considered based only on the parenchymal arrangements, were the adenoid, compact, plexiform Pinkus fibroepithelioma, pseudocystic, reticulated, superficial and trichoepithelioid, though predominantly the adenoid form (28.3%. The mean growth involved 2/3 of the reticular dermis (32.4%, and the deepest tumors presented intense fibroplasia. There was concomitance of several cellular types within a single tumor and melanin pigment was found mostly in the trichoepithelioid type. CONCLUSION: The clinical and anatomopathological characterization of the basal cell carcinomas is of fundamental importance at these services, where there is no major difference between groups, calling attention to behavioral definitions and propositions for the

    Objective:To investigate the significance of telomerase activity in breast carcinoma with its respect to axillary lymph node status. Methods: Telomerase activity was analyzed in 88 breast carcinomas and 16benign breast lesions, using polymerase chain reaction (PCR)-based telomeric repeat amplification protocol (TRAP) assay. Results: Telomerase activity was detected in 75 (85%) of 88 breast carcinomas (including three breast carcinomas in situ which were all positive for telomerase activity), whereas in benign breast lesions analyzed only 2(12.5%) of 16 cases were positive for telomerase activity. The difference between the two groups was statistically significant (P<0.001). Besides,telomerase activity was expressed significantly higher in node-positive breast carcinoma (93%) than in nodenegative ones (77%) (P<0.05). Conclusion: Our results suggest that telomerase activation plays an important role during breast carcinoma development. It is possible that this enzyme may serve as an early indication of breast carcinoma.

    To study the magnitude of radiation cystitis following radiation therapy for carcinoma cervix, and propose an algorithm to decide on early diversion, with or without vesicovaginostomy. Women who developed radiation cystitis following radiotherapy for carcinoma cervix from January 1998 to December 2011 were included in this retrospective study. Electronic hospital records were analysed to document the presence of radiation cystitis. All women who developed evidence of radiation-induced cystitis, according to the common toxicity and Radiation Therapy Oncology Group criteria, were included in the study. We looked at transfusion requirements, number of hospital admissions, quality of life and cost involved. Chi-square tests were done where applicable. SPSS version 16 was used for analysis. Of the 902 patients who received radiation for carcinoma cervix in the 13-year period, 62 (6.87%) developed grade 3/4 cystitis. Twenty-eight of them underwent ileal conduit diversion, with 18 undergoing concomitant vesicovaginostomy. When compared with the patients who did not have diversion, the transfusion requirements, number of hospital admissions and quality of life had a statistically significant difference. Cost analysis of early diversion too showed a marginal benefit with early diversion. The limitation of the study was that it was retrospective in nature. In radiation cystitis, multiple hospital admissions and consequential increase in cost is the norm. In severe disease, early diversion is a prudent, cost-effective approach with good quality of life and early return to normal activity. © 2014 Royal Australasian College of Surgeons.

    Thirty-six patients of ear carcinoma treated in our department were clinically analyzed. Those ear carcinoma patients accounted for 3.5% of all head and neck carcinoma patients. The most common primary site was the external auditory canal (67%), followed by the middle ear (19%) and the auricle (14%). The mean age of the patients was 66 years old, and the male to female ratio was 3:2. The most common chief complaint of the external auditory canal and middle ear carcinoma was otorrhea followed by ear itching and ear ache. Of patients with external auditory canal carcinoma and middle ear carcinoma, 26% had a history of ear surgery, and 35% had a habit of ear-picking. Histopathologically, 94% of the patients were squamous cell carcinoma, and 6% were malignant melanoma. Sixty-two % of squamous cell carcinoma patients underwent surgery, and the remaining 38% had radiotherapy without surgery. Postoperative radiotherapy was added for 67% of the surgery group. Five-year survival rates of the patients with squamous cell carcinoma were 74% for external auditory canal carcinoma, 67% for auricular carcinoma, and 34% for middle ear carcinoma, respectively. The five-year survival rate of the surgery group was 82%, and that of the non-surgery group was 29%. There was a statistical significance between the two groups. No statistical significance was seen between with and without postoperative radiotherapy. In the treatment of squamous cell carcinoma in the ear, radical en bloc surgery followed by postoperative radiotherapy was considered to be an appropriate treatment strategy. (author)

    Primary intraosseous squamous cell carcinoma (PIOSCC) is a rare carcinoma, which arises within the jaws without connection to the oral mucosa and presumably develops from a remnant of odontogenic epithelium. We present a case of solid type PIOSCC in a 52-year-old male patient complaining of dull pain on his left lower molar. In this case, early stage PIOSCC mimicking a periapical lesion might lead to a one-year delay in treatment due to the misdiagnosis of osteomyelitis after extraction of the third molar. The clinical, radiological, and histologic features are described. In this case, there was initial radiographic evidence for PIOSCC mimicking a periapical lesion. Incautious radiographic interpretation and treatment procedures had delayed the correct diagnosis and resulted in extensive bony destruction during the patient's disease progression.

    Full Text Available Invasive head and neck squamous carcinomas are among the cytogenetically most complex tumors. Perhaps for this reason, there is little consensus on the prognostic value of specific chromosomal aberrations. Here we present Results of CGH analysis of 56 clinically well-characterized set of head and neck cancers, consisting of larynx and pharynx only. The aim was to find possible associations with clinical outcome. The major chromosome arms showing gains were (in decreasing order: 3q, 7q, 8q, 5p, 11q13, 17q and 18p, and losses occurred at 3p, 11qter, 4p, 18q, and 5q. The segments most frequently amplified were 3q26-qter, 11q13, 11q22, 3q12–13, 18p11.3, 18q11.2 and 8q24.3. Tumors with stages III and IV, and lymph node positive tumors had a worse clinical outcome. Surprisingly, no specific chromosomal abnormality correlated with disease-free survival. The only aberration that correlated to one of the clinico-pathological parameters was amplification 11q13, that occurred solely in lymph node positive, stage IV tumors. However 11q13 amplification did not correlate with disease-free survival. These Results seem to indicate that genetic alterations at the level of chromosomes have limited prognostic value in patients with invasive larynx and pharynx squamous cell carcinomas.

    The frequency of hepatocellular carcinoma (HCC) is increasing in the western world and the role of radiotherapy is more and more discussed. Classically, hepatocellular carcinoma was considered as a radioresistant tumour: in fact, modern radio-biologic studies, performed on cell lines directly established from patients, showed that hepatocellular carcinoma has the same radiosensitivity than the other epithelial tumours. From clinical studies, its α/β ratio has been estimated to be around 15 Gy. Radiosensitivity of normal hepatic parenchyma is now well evaluated and some accurate NTCP models are available to guide hepatic irradiation. The biology of hepatocellular carcinoma is also better described: the combination of radiotherapy and targeted therapies will be a promising approach in the near future. (authors)

    Vulvar carcinoma is a rare tumor of the female genital tract. In Nigeria, very few studies have looked at the management options for vulvar carcinoma. The objective of this study was therefore, to describe the management options available and the challenges in treating this malignancy in Nigeria. A descriptive study of all vulvar cancer cases managed at the Nnamdi Azikiwe University Teaching Hospital, Nnewi over a 12 year period (1998-2009). The theatre, ward register, histo-pathologic records and case notes of all women who had surgery for vulvar carcinomas were retrieved and socio-demographic characteristics, clinical presentation, type of surgery, histologic type and complications of treatment were retrieved and analyzed. There were 867 gynecological malignancies and vulval carcinoma accounted for 11 cases, giving a prevalence of 1.27%. The ages ranged from 54 to 79 years with a mean of 61.2 years. Parity was 2-14, with a mean of 6.7 ± 2.33. Most of the patients were of low socio-economic class. All the 11 patients had surgery as 1st line treatment. Radical vulvectomy was done for 6 cases since they presented in the advanced stage. The complications of surgery included hemorrhage (18.2%), chronic lymphedema, wound infection and anesthetic complications. There were no hospital mortalities. Late presentation, with stage III (45.4%) was the commonest stage at presentation while the majority of the vulvar carcinomas (72.7%) were of epithelial origin. Squamous cell carcinoma predominated (63.6%). Carcinoma of the vulva is a rare gynecological malignancy in Nigeria. Surgery and radiotherapy remains the mainstay of this disease in Nigeria and can be highly successful if patients present early.

    Full Text Available Primary Fallopian Tube Carcinoma (PFTC is rare and accounts for about 0.3% of all gynecologic cancers. Less than 1500 cases have been reported in the literature. It arises in postmenopausal women and typically presents with abdominal pelvic pain, vaginal bleeding and watery discharge. However, a correct diagnosis is rarely achieved preoperative, and in many cases, the diagnosis is made after incidental surgery for unrelated conditions commonly being ovarian carcinoma . Compared with ovarian carcinoma, PFTC more often presents at early stages, but it has a worse prognosis. PFTC is usually managed in the same manner as ovarian cancer. We report a case of Left PFTC that presented as Left ovarian mass, and we briefly review the literature.

    To compare the clinicopathologic features and prognosis of Chinese patients with ovarian clear cell carcinoma (CCC) and serous carcinoma (SC). A retrospective cohort study was designed to investigate the clinicopathologic characteristic and prognosis of patients with CCC and SC who were diagnosed and treated in in a tertiary referral center (Peking Union Medical College Hospital) between 1999 and 2009. The Kaplan-Meier method and Cox regression were employed in the survival analysis. A total of 504 cases were included in the study, comprising 197 cases of CCC and 307 cases of SC. The mean age of the patients with SC was greater than of CCC patients (3.6±0.94, PPatients with CCC were more likely to be early-stage and optimally debulked (Ppatients with CCC had normal values, and the level was significantly lower than in patients with SC (Ppatients had platinum-resistant tumors compared with platinum-sensitive disease (45.7% in CCC vs. 61.0% in SC [P=0.008]). The 5-year survival rate was 51.2% in the CCC group vs. 49.8% in the SC group (P=0.428). Patients with advanced CCC had a statistically significant poorer overall survival (OS) compared with their SC counterparts (38.0 vs. 52.0 months; hazard ratio 1.584, 95% confidence interval [CI] 1.167-2.150, P=0.003). However, the advantage of improved progression-free survival (PFS) existed across all stages. Women with ovarian CCC presented at a younger age and early stage. Patients with ovarian CCC also had improved PFS, but they had similar OS compared to patients with SC. However, patients with advanced CCC had decreased survival.

    Full Text Available Abstract Introduction Tumors can metastasize to the oral cavity and affect the jaws, soft tissue and salivary glands. Oral cavity metastases are considered rare and represent approximately 1% of all oral malignancies. Because of their rarity and atypical clinical and radiographic appearance, metastatic lesions are considered a diagnostic challenge. The purpose of this report is to present a rare case of a metastatic breast carcinoma mimicking a periodontal abscess in the mandible. Case presentation A 55-year-old Caucasian woman was referred to our clinic for evaluation of bisphosphonate-induced jaw osteonecrosis. She had undergone modified radical mastectomy with axillary lymph node dissection for invasive ductal carcinoma of the left breast. Her clinical examination showed diffuse swelling and a periodontal pocket of 6 mm exhibiting suppuration in the posterior right mandible. Moreover, paresthesia of the lower right lip and chin was noted. There were no significant radiographic findings other than alveolar bone loss due to her periodontal disease. Although the lesion resembled a periodontal abscess, metastatic carcinoma of the breast was suspected on the basis of the patient's medical history. The area was biopsied, and histological analysis confirmed the final diagnosis of metastatic breast carcinoma. Conclusion The general dentist or dental specialist should maintain a high level of suspicion while evaluating patients with a history of cancer. Paresthesias of the lower lip and the chin should be considered ominous signs of metastatic disease. This case highlights the importance of the value of a detailed medical history and thorough clinical examination for the early detection of metastatic tumors in the oral cavity.

    To determine, with the use of polymerase chain reaction, the prevalence of human papillomavirus (HPV) 16 in 30 patients with primary oral squamous cell carcinoma (OSCC) and 30 healthy control patients. DNA was extracted from freshly frozen tumor tissues of 30 patients with primary oral squamous cell carcinoma and from the oral mucosa of 30 controls. A pair of specific primers of the E7 early gene of HPV 16 were designed. PCR products were run by 1.5% agarose gel and the results of electrophoresis were photographed. HPV 16 was detected in 36.7% (11/30) of oral squamous cell carcinoma patients and 11.1% (4/30) of controls. HPV 16 has a significant association with oral squamous cell carcinoma. However, the role HPV 16 plays in the tumorigenesis of oral cancer and its clinical significance remain to be investigated.

    Akt/protein kinase B (PKB) plays an important role in cell survival. However, the role of Akt in the biology of gastric cancer has not been well studied. We sought to investigate the expression of Akt or phosphorylated Akt (pAkt) in human gastric carcinomas and to analyze the relationship between Akt or pAkt and the clinicopathologic parameters. The expressions of Akt and pAkt were evaluated immunohistochemically in 311 gastric carcinomas using the tissue array method. Akt expression was detected in 74% of the tumors and pAkt expression in 78%. pAkt was highly expressed in the early stage of pTNM (p=0.011). We also found an inverse association between pAkt and lymphatic invasion (p=0.01) or lymph node metastasis (p=0.008). pAkt expression was significantly correlated with a higher survival in patients with stage I carcinomas (p=0.0003). Interestingly, combined evaluation revealed that the group with pAkt-positive and lymph node-negative carcinomas showed a better prognosis than the other groups (pSmad4 (p<0.0001) expression. These findings suggest that pAkt expression may help to predict the clinical outcome of gastric cancer patients.

    This study evaluated early bowel complications in cervix cancer patients, following external radiotherapy (ERT) and high dose rate intracavitary radiation (HDR ICR). Factors affecting the risk of developing early bowel complications and its incidence are analyzed and discussed. The study is the retrospective review of 66 patients who received radiotherapy at Chungbuk National University Hospital from April 1994 to December 1998. The patients underwent 41.4 or 50.4 Gy ERT according to FIGO stage and tumor size, then A point dose was boosted to 71.4 or 74.4 Gy using a remotely controlled after loading Buchler HDR ICR. The EORTC/RTOG morbidity criteria were used to grade early bowel complications, which are valid from day 1, the commencement of therapy, through day 90. The actuarial incidence, severity of complications were investigated and clinical pretreatment factors relevant to complications were found through univariate (Wilcoxon) and multivariate (Cox proportional hazard model) analysis. Of the 66 patients, 30 patients (46%) developed early bowel complications; 25 patients (38%) with grade 1 or 2, 4 patients (6%) with grade 3 and 1 patient (2%) with grade 4. The complications usually began to occur 3 weeks after the commencement of radiotherapy. The actuarial incidence of early bowel complications was 41% at 10 weeks. The early bowel complications were associated significantly with an old age and a history of previous abdomino-pelvic surgery. All three patients who had a protracted overall treatment time (about 2 weeks) due to severe bowel complication, suffered from pelvic recurrences. Forty six percent of patients experienced early bowel complications, most of which were grade 1 or 2 and relieved spontaneously or by medication. The patients with an old age or a previous surgery have a high probability of early complications and they may be less compliant with planned radiotherapy. So more careful precaution is necessary for these patients

  1. Laryngeal adenoid cystic carcinoma: case report

    Directory of Open Access Journals (Sweden)

    André Del Negro

    Full Text Available CONTEXT: Adenoid cystic carcinomas are malignant tumors that occur in both the major and the minor salivary glands. A laryngeal location is rare because of the paucity of accessory salivary glands in this area. Adenoid cystic carcinomas account for less than 1% of all malignant tumors in the larynx, and only about 120 cases have been reported in the literature. These tumors have a slight female predisposition, and their peak incidence is in the fifth and sixth decades of life. In this article, we describe a case of laryngeal adenoid cystic carcinoma and discuss its clinical characteristics and treatment. CASE REPORT: We report on a case of laryngeal adenoid cystic carcinoma in a 55 year-old female patient who presented with dyspnea and hoarseness. Features of the diagnostic and therapeutic evaluation are described and the clinical management of such cases is outlined. The clinical course, definitive treatment strategy and surgical procedure, and also adjuvant treatment with irradiation are discussed. Although the tumor is radiosensitive, it is not radiocurable.

    In the past three decades, the detection rate of ductal carcinoma in situ of the breast has dramatically increased due to breast screening programs. As a consequence, about 20% of all breast cancer cases are detected in this early in situ stage. Some ductal carcinoma in situ cases will progress to invasive breast cancer, while other cases are likely to have an indolent biological behavior. The presence of tumor-infiltrating lymphocytes is seen as a promising prognostic and predictive marker in invasive breast cancer, mainly in HER2-positive and triple-negative subtypes. Here, we summarize the current understanding regarding immune infiltrates in invasive breast cancer and highlight recent observations regarding the presence and potential clinical significance of such immune infiltrates in patients with ductal carcinoma in situ. The presence of tumor-infiltrating lymphocytes, their numbers, composition, and potential relationship with genomic status will be discussed. Finally, we propose that a combination of genetic and immune markers may better stratify ductal carcinoma in situ subtypes with respect to tumor evolution.

    Adnexal carcinomas are rare and diverse cutaneous tumours. They are locally aggressive and have the potential for distant metastasis. Metastatic adnexal carcinomas are very resistant to conventional chemotherapies. Sunitinib, an oral tyrosine kinase inhibitor, is reportedly effective for the treatment of various solid cancers. Its use in adnexal carcinomas has never been reported. The first patient had metastatic clear cell hidradenocarcinoma and was stabilized over 8 months with sunitinib, before she relapsed. The second patient had a metastatic malignant hair follicle tumour (trichoblastic carcinoma) and achieved a partial remission with sunitinib, and disease stabilized after 10 months. Dynamic contrast-enhanced ultrasound (DCE-US) performed to evaluate tumour vascularization during treatment depicted a dramatic and early decrease in the tumour blood volume. Sunitinib was effective in controlling the disease in our two patients. DCE-US using linear raw data may have an early predictive value for tumour response to sunitinib. Further studies involving larger cohorts of patients are warranted in order to confirm the efficacy of sunitinib in these rare tumours.

    Nevoid basal cell carcinoma syndrome (NBCC; Gorlin syndrome), an autosomal dominant disorder linked to 9q22.3-q31, and caused by mutations in PTC, the human homologue of the Drosophila patched gene, comprises multiple basal cell carcinomas, keratocysts of the jaw, palmar/plantar pits, spine and rib anomalies and calcification of the falx cerebri. We reviewed the findings on 105 affected individuals examined at the NIH since 1985. The data included 48 males and 57 females ranging in age from 4 months to 87 years. Eighty percent of whites (71/90) and 38% (5/13) of African-Americans had at least one basal cell carcinoma (BCC), with the first tumor occurring at a mean age of 23 (median 20) years and 21 (median 20) years, respectively. Excluding individuals exposed to radiation therapy, the number of BCCs ranged from 1 to >1,000 (median 8) and 1 to 3 (median 2), respectively, in the 2 groups. Jaw cysts occurred in 78/105 (74%) with the first tumor occurring in 80% by the age of 20 years. The number of total jaw cysts ranged from 1 to 28 (median 3). Palmar pits and plantar pits were seen in 87%. Ovarian fibromas were diagnosed by ultrasound in 9/52 (17%) at a mean age of 30 years. Medulloblastoma occurred in 4 patients at a mean age of 2.3 years. Three patients had cleft lip or palate. Physical findings include {open_quotes}coarse face{close_quotes} in 54%, relative macrocephaly in 50%, hypertelorism in 42%, frontal bossing in 27%, pectus deformity in 13%, and Sprengel deformity in 11%.

    syndrome (GGS is an autosomal dominant inherited disorder that mainly predisposes to the proliferation of tumors, such as basal cell carcinomas and jaw keratocysts. GGS is caused by the Patched gene mutation on chromosome 9. Basal cell carcinomas in patients with GGS usually present as multiple tumors, with polymorphic clinical features, a non-gender predilection, sometimes occurring in the early stages of life, and even affecting areas not exposed to sunlight. The clinical behavior may vary, and sometimes can be very aggressive, especially in the face. In order to study the behavior of basal cell carcinomas in GGS patients, a study was performed on the patients who met criteria for the disease and were treated in our hospital in the period between 2001 and 2011. Material and methods: The study included 11 patients with clinical and/or genetic diagnosis of GGS. The patients were studied according sex and age, clinical aspects, histological features, surgical treatment provided, presence of recurrence, and follow-up. Results: Basal cell carcinomas were seen on the face in 36% of the patients. The number of tumors per patient ranged between 9 and 21. The preferred treatment was surgical excision, although all patients developed new lesions and recurrences which required several procedures. The histological study revealed a contact or proximity of the tumor to surgical margins in 28% of lesions. Conclusions: There is insufficient evidence in the literature to determine the treatment of choice among the different methods available for the management of the basal cell carcinoma in GGS. A preventive approach is necessary to avoid sunlight exposure.

    A commercial ''SCC RIABEAD'' kit for immunoradiometric assay of squamous cell carcinoma related antigen (SCC antigen) was fundamentally and clinically evaluated. Laboratory performance was satisfactory for intra-assay and inter-assay reproducibility, recovery, and dilution, with rapid and simple measurement techniques. Seropositivity for SCC antigen was significantly higher for squamous cell carcinoma of the liver and uterine cervix than the other histology types. In the case of cervical squamous cell carcinoma, it increased with progressing disease. Post-treatment serum levels of SCC antigen returned to negative. SCC antigen is considered to be a useful tumor marker for these diseases. There was a good correlation between the measurement values obtained from the present and conventional (SCC RIAKIT) assays. The present assay remarkably decreased false-positive cases of pulmonary benign diseases. The results showed a ''SCC RIABEAD'' to be a favorable kit for immunoradiometric assay of SSC antigen, as compared with conventional assay kit. (Namekawa, K.)

    Purpose: To compare radiation doses to carotid arteries among various radiotherapy techniques for treatment of early-stage squamous cell carcinoma (SCC) of the true vocal cords. Methods and Materials: Five patients were simulated using computed tomography (CT). Clinical and planning target volumes (PTV) were created for bilateral and unilateral stage T1 vocal cord cancers. Planning risk volumes for the carotid arteries and spinal cord were delineated. For each patient, three treatment plans were designed for bilateral and unilateral target volumes: opposed laterals (LATS), three-dimensional conformal radiotherapy (3DCRT), and intensity-modulated radiotherapy (IMRT), for a total of 30 plans. More than 95% of the PTV received the prescription dose (63Gy at 2.25 Gy per treatment). Results: Carotid dose was lowest with IMRT. With a bilateral vocal cord target, the median carotid dose was 10Gy with IMRT vs. 25 Gy with 3DCRT and 38 Gy with LATS (p < 0.05); with a unilateral target, the median carotid dose was 4 Gy with IMRT vs. 19 Gy with 3DCRT and 39 Gy with LATS (p < 0.05). The dosimetric tradeoff with IMRT is a small area of high dose in the PTV. The worst heterogeneity results were at a maximum point dose of 80 Gy (127%) in a unilateral target that was close to the carotid. Conclusions: There is no question that IMRT can reduce the dose to the carotid arteries in patients with early-stage vocal cord cancer. The question is whether the potential advantage of reducing the carotid dose outweighs the risk of tumor recurrence due to contouring errors and organ motion and the risk of complications from dose heterogeneity.

    Full Text Available Background: Photodynamic therapy is frequently applied for non-invasive destruction of basal cell carcinomas (BCC of the skin; though, there is lack of evidence for efficacy of the method. Aim: To assess objective response of BCCs to photodynamic therapy with intralesional administration of photosensitizer Radachlorin in patients with different clinical forms, stages, flow patterns and localization of BCC. Materials and methods: 45  stage I–II BCCs patients with primary and recurrent solitary (ulcerative, superficial, scleroderma-like and nodular forms and multiple lesions (predominantly Т₁– Т₂N₀M₀, with difficult to treat localization and high risk of recurrence were included during the period from March 2004 to March 2007. All patients received one cycle of photodynamic therapy with intralesional Radachlorin (0.5–1  ml/1  cm² tumor surface and irradiation dose 300  J/cm² (wavelength 662 nm. A primary outcome measure was grade of clinical and cytological lesion regression after three months. Secondary outcome measure was stable clinical and cytological reaction at the lesion site. In the long-term, lesion recurrence was assessed yearly during 5 years. Results: Complete regression of BCCs was found in 43  (95.5% patients and 47  (95.9% lesions. In 2 (4.5% patients with partial regression of 2 (4.1% lesions repeated cycles of photodynamic therapy resulted in complete response. In BCCs Т₁N₀M₀, early outcome was independent from the clinical form of the diseases; by contrast, in BCCs Т₂N₀M₀, treatment of scleroderma-like BCCs was non-significantly less effective (66.7% compared to nodular, surface (100% for both and ulcerative (92.8% forms. In the long-term, 1  tumor recurrence was observed after 29 months at the site of completely regressed ulcerative lesion. Conclusion: Photodynamic therapy with intralesional administration of photosensitizer Radachlorin is an effective treatment method for different

    Alpha-fetoprotein is an effective biomarker as an aid in hepatocellular carcinoma detection in many countries. However, alpha-fetoprotein has its limitations, especially in early hepatocellular carcinoma diagnosis. Protein induced by vitamin K absence or antagonist-II is another biomarker that is used for hepatocellular carcinoma detection. The aim of this study is to compare the diagnostic performance of alpha-fetoprotein and protein induced by vitamin K absence or antagonist-II alone and in combination to explore improving biomarker performance as an aid in early hepatocellular carcinoma detection. In this study a total of 582 serum samples including 132 hepatocellular carcinoma patients, 250 non-hepatocellular carcinoma patients, and 200 healthy volunteers were collected. Alpha-fetoprotein and protein induced by vitamin K absence or antagonist-II levels were measured by both chemiluminescent enzyme immunoassay on LUMIPULSE platform and by chemiluminescent microparticle immunoassay on ARCHITECT platform. Receiver operation characteristic curve analyses were performed for each biomarker and in combination. The results showed that Alpha-fetoprotein and protein induced by vitamin K absence or antagonist-II in combination have shown higher area under the curve compared to alpha-fetoprotein alone for diagnosis in whole patients (0.906 vs 0.870) in hepatocellular carcinoma early-stage patients (0.809 vs 0.77) and in hepatitis B virus-related hepatocellular carcinoma patients (0.851 vs 0.788) with ARCHITECT platform. Protein induced by vitamin K absence or antagonist-II showed higher area under the curve than alpha-fetoprotein for diagnosis of hepatitis B virus-related hepatocellular carcinoma patients (0.901 vs 0.788).We conclude that Combining alpha-fetoprotein and protein induced by vitamin K absence or antagonist-II may improve the diagnostic value for early detection of hepatocellular carcinoma. Protein induced by vitamin K absence or antagonist-II performs better

    Hemodynamic characteristics were studied by using in vivo vascular imaging techniques in 17 resected early stage hepatocellular carcinoma (e-HCC) by comparing them with 49 resected advanced HCCs (ad-HCC) less than 3 cm in diameter. In this study, e-HCC was defined as the nodule being uniformly composed of well-differentiated HCC or adenomatous hyperplastic nodule containing well-differentiated HCC foci within the nodule. In vivo vascular imaging techniques are as follows; US angiography with intraarterial CO 2 microbubbles were performed to assess the tumor arterial vascularity, and CT during arterial portography (CTAP) was performed to assess the portal perfusion within the nodule. Of 17 e-HCC nodules 5 were hypervascular, 5 were isovascular, 4 were hypovascular, and 3 were vascular spot in hypovascular pattern in contrast to 49 ad-HCC nodules, 43 of which were hypervascular and 6 were isovascular. Of 14 e-HCCs, 9 nodules showed perfusion defect and 5 did not on CTAP, whereas all 37 ad-HCCs on which CTAP was performed, showed perfusion defect. Forty-one percent (7/17) of e-HCC showed fatty metamorphosis in contrast to 8% (4/49) of ad-HCC. In conclusion, hemodynamic characteristics of e-HCC are summarized as follows. (1) Arterial tumor neovascularization is relatively low. (2) Portal perfusion is present in some of e-HCC cases. (3) Hypoperfusion state both from arterial and portal supply is present in some of e-HCC cases. (4) Vascular spot in hypovascular pattern is characteristic arterial pattern in AH containing HCC foci. (5) Fatty metamorphosis may be related with hypoperfusion state of the nodule in e-HCC. (author)

    Identifying patients at high risk for readmission early during hospitalization may aid efforts in reducing readmissions. We sought to develop an early readmission risk predictive model using automated clinical data available at hospital admission. We developed an early readmission risk model using a derivation cohort and validated the model with a validation cohort. We used a published Acute Laboratory Risk of Mortality Score as an aggregated measure of clinical severity at admission and the number of hospital discharges in the previous 90 days as a measure of disease progression. We then evaluated the administrative data-enhanced model by adding principal and secondary diagnoses and other variables. We examined the c-statistic change when additional variables were added to the model. There were 1,195,640 adult discharges from 70 hospitals with 39.8% male and the median age of 63 years (first and third quartile: 43, 78). The 30-day readmission rate was 11.9% (n=142,211). The early readmission model yielded a graded relationship of readmission and the Acute Laboratory Risk of Mortality Score and the number of previous discharges within 90 days. The model c-statistic was 0.697 with good calibration. When administrative variables were added to the model, the c-statistic increased to 0.722. Automated clinical data can generate a readmission risk score early at hospitalization with fair discrimination. It may have applied value to aid early care transition. Adding administrative data increases predictive accuracy. The administrative data-enhanced model may be used for hospital comparison and outcome research.

    Ovarian carcinoma is the deadliest gynecological malignancy. Previous studies have suggested that the fallopian tube may be the primary site for high-grade serous carcinoma. In prophylactic salpingo-oophorectomies from women with hereditary high risk for ovarian cancer, precursors can be assessed prior to onset and studied as a model for serous cancer precursor lesions. Epidemiologic studies indicate that carcinogenesis may be a result of chronic fallopian tube injury. The aims of this study were to (1) to examine the incidence of serous tubal intraepithelial carcinoma (STIC) in relation to other clinical parameters and (2) to evaluate whether chronic fallopian tube injury was related to cancer development. This study enrolled 101 women, comprising the following three groups: hereditary (n = 60), sporadic serous cancer (n = 18; endometrial cancers were excluded), and control (n = 23). The cases were histologically examined and clinical risk factors were collected. The histological changes were compared between different patients and correlated to clinical risk factors. STICs were identified primarily on the fallopian tube fimbria. The incidence of STIC was 3 % in the hereditary patients. In sporadic serous cancer cases, 61 % were associated with STIC and tubal carcinoma (p STIC and invasive cancer were seen more often in the older patients than in the younger patients (p = 0.528). This small study, no correlation with chronic tubal injury or inflammation was identified.

    Atypical ductal hyperplasia (ADH) and lobular carcinoma in situ (LCIS) may be associated with a relatively high incidence of invasive carcinoma and ductal carcinoma in situ (DCIS) on immediate excision when found on core needle biopsy of the breast. However, the long term significance of ADH and LCIS in a breast core needle biopsy is not as well characterised. We reviewed the results of all breast core needle biopsies with a diagnosis of ADH or LCIS and immediate excision from the years 2000-2004, and correlated the results with long term clinical follow-up. Of 175 biopsies with ADH, 53 (30.3%) had carcinoma (8 invasive, and 45 DCIS) at the time of immediate re-excision. Of 69 biopsies with LCIS, three (4.3%) had carcinoma (2 invasive, and 1 DCIS) at the time of immediate re-excision. A total of 14 (11.5%) patients with ADH and benign re-excisions developed invasive carcinoma (12) or DCIS (2) on follow-up. A total of 17 (25.8%) patients with LCIS and benign re-excisions developed invasive carcinoma (13) or DCIS (4) on follow-up. The risk of invasive carcinoma or DCIS on immediate re-excision was significantly higher for women with ADH than LCIS (pfibrocystic changes (FCC) on core needle biopsy, the risk of developing invasive carcinoma or DCIS was significantly higher for women with ADH and benign initial re-excisions (95% CI 1.092-7.297, p=0.03), and women with LCIS and benign re-excisions (95% CI 3.028-18.657, p<0.001). Overall, 67/175 (38.3%) women with ADH and 20/69 (29.0%) women with LCIS on core needle biopsy either had carcinoma at the time of the biopsy or later developed carcinoma. Significantly more women with LCIS developed invasive carcinoma or DCIS than women with ADH on long term follow-up. The relative risk for ADH and LCIS on core biopsy with a negative excision compared with FCC was similar to that reported in the literature (ADH 1-7×, LCIS 3-19×).

    The increase of thyroid gland cancer in people of Belarus is one of the most actual medical problems appeared after the Chernobyl disaster. During the period 1986 -1999 in Belarus were revealed 6901 cases of cancer in the adults and 673 -in the children. Compared with the pre-disaster period the increase of the pathology has made 4.7 and 84 times correspondingly. In Magilew region during post-disaster years were revealed 899 cases of thyroid gland cancer in the adults and 34 -in the children. From the year 1998 perceptible rise of disease appeared in people over 19 years old. According to the prognosis of specialists the problem of high thyroid gland carcinoma rate will be actual for years, gradually decreasing in the children and increasing in the adults. Thyroid gland cancer promoted by radiation has very aggressive nature. According to the data of Republican science-practical thyroid gland tumors center even small carcinomas (3-9 mm) can give numerous metastasis to lymph nodes and lungs. The possibility of tumor growth to the nearest tissues is very high. That's why the early diagnostic of the pathology is important. Medical help to the patients with thyroid gland cancer and other node formations consist in the complex problem solution: early node formation revealing by ultrasonic method, early diagnosis verification with the help of cytological bio-assays examination, received by the way of the thin needle aspiration biopsy (TNAB) under ultrasonic control, surgical treatment, radio iodine therapy, rehabilitation and prophylactic medical examination. Under the problem of early thyroid carcinoma revealing they understand exact diagnostic and surgical treatment in the stages pT1, pT1a and pT1b, N0, M0. In 1993 -1999 in the diagnostic center 139,2 thousand patients were surveyed. In the pointed cases 10739 thin needle aspiration biopsies under ultrasonic control were made and the bioassays received were studied cytologically. Ultrasonic examinations and TNAB were

    Full Text Available Background and objective It has been proven that CD147 was an extracellular matrix metalloproteinase inducer reportedly involved in the invasion and metastasis of malignancies. The aim of this study is to investigate CD147 and MMP-2 expression in squamous cell carcinoma and adenocarcinoma of the lungs and to analyze their clinical significance. Methods Tissue samples from 55 patients with squamous cell carcinoma and adenocarcinoma of the lungs and their corresponding non-cancerous tissues were examined for CD147 and MMP-2 expression using immunohistochemistry. Results The positive expression rates of CD147 and MMP-2 in the squamous cell carcinoma and adenocarcinoma among the lung tissues were significantly higher than those in the corresponding normal lung tissues. Moreover, the CD147 and MMP-2 expression in squamous cell carcinoma and adenocarcinoma of the lungs were related to lymph node metastasis and TNM stages (P<0.05, but not to age, gender and histologic type (P>0.05. MMP-2 expression was highly correlated with CD147 expression. Conclusion CD147 and MMP-2 expression is correlated with the invasion and metastasis of squamous cell carcinoma and adenocarcinoma of the lungs and may be used as objective markers for predicting the behavior of squamous cell carcinoma and adenocarcinoma of the lungs.

    In the department of radiotherapy of the 1st University-Clinic of Gynaecology and Obstetrics in Vienna the electroresection and electrocoagulation is practiced with good success in the treatment of carcinoma of the vulva. Of 386 treated cases with vulvar carcinoma, 234 (60,6%) were alive after five years. After surgical treatment the inguinal lymphonodes were irradiated (6000 rad). In comparison with the international statistic of the Annual Report of the results of treatment in gynaecological cancer (1979) the results obtained in Vienna are much better than the international average.

    Objective: To investigate the clinical values of preoperative arterial infusion chemotherapy and surgical operation for colorectal carcinoma. Methods: 66 patients with colorectal carcinoma were subjected to percutaneous femoral artery catheterization by Seldinger's technique with infusion of anti-cancer drugs. The resection was performed 5-30 days after the arterial infusion (mean 12 days). In 50 surgical specimens of the 66 cases, histological findings were evaluated including the density and distribution of the apoptosis cells under the observation by DNA nick end labelling technique. Of which 22 specimens before arterial infusion chemotherapy (got from biopsy of preoperation) and 25 normal mucosa (got from normal surgical specimens) were used as controls. Results: The total histological response rate was 100% with grade I in 20 cases, grade II in 21 cases, grade III in 9 cases. The densities of the apoptosis cells were 31.47 ± 5.58 before arterial infusion chemotherapy, 76.69 ± 17.12 after arterial infusion chemotherapy and 8.01 ± 3.39 in normal mucosa. The density of the apoptosis cells after arterial infusion chemotherapy was significantly higher than that before arterial infusion chemotherapy (P 2 =4.696, P>0.30). There were no significant differences in the apoptosis of adenocarcinoma during different pathological stages (F=0.001376, P>0.05). Conclusions: Peroperative transcatheter arterial infusion chemotherapy resulting in apoptosis of adenocarcinoma, can raise the radical operation rate, and prolong survival rate for colorectal carcinoma patients

    Full Text Available Objective To determine the expression and clinical significance of circ-PVT1 in human hepatocellular carcinoma (HCC and its effect on HCC cell proliferation. Methods The expressions of circ-PVT1 in hepatocellular carcinoma and the matched tumor-adjacent tissues were detected by RT-qPCR and the relationship between pathological indexes and the expression level was analyzed in 46 patients. The expressions of circ-PVT1 in human normal liver cell line (L02 and hepatocellular carcinoma cell lines (HepG2, SMMC-7721, MHCC-97H, MHCC-97L, HCC-LM3 were detected by RT-qPCR and were compared thereafter. With knocking down the expression of circ-PVT1, si-circPVT1 was transfected into HepG2 and SMMC-7721 cells by using lipofectamine technique in vitro, with the si-NC being taken as negative control. After interfering the expression of circ-PVT1, the effect on the proliferation of hepatocellular carcinoma cells was detected by CCK-8 and EDU experiments and flow cytometry was conducted to observe the effect of circ-PVT1 on cell cycle. Results The expression level of circ-PVT1 was significantly higher in HCC tissues than in adjacent tissues (P<0.01, and its high expression level was significantly correlated with tumor size, TNM stage and differentiation degree. Similarly, in human hepatocellular carcinoma cell lines (HepG2, SMMC-7721, MHCC-97H, MHCC-97L, HCC-LM3, the expression level of circ-PVT1 was also higher than that in human normal liver cell line L02 (P<0.05. Compared with the negative control group, silencing of circ-PVT1 resulted in remarkable reduction in cell proliferation of HepG2 and SMMC-7721. Conclusion circ-PVT1 may act as a potential biomarker for HCC diagnosis and may become a novel proliferation factor. DOI: 10.11855/j.issn.0577-7402.2018.03.06

    To compare treatment outcomes of subcentimeter hypervascular nodules at high risk for developing into hepatocellular carcinomas (SHNHR) between early treatment and watchful waiting until progression to overt hepatocellular carcinoma (HCC) groups. SHNHRs were defined as subcentimeter hypervascular nodules with the usual imaging features of HCC on gadoxetic acid-enhanced magnetic resonance imaging (MRI). Among 63 patients with 74 SHNHRs, 27 (37 SHNHRs) received early treatment (treatment of < 1 cm nodules), and 36 (37 SHNHRs) underwent watchful waiting until progression to overt HCC. Risk factor analysis was performed for recurrence-free and local recurrence-free survival. Among the 36 patients who adopted watchful waiting, 33 eventually underwent treatment because their SHNHRs progressed to overt HCC. For recurrence-free survival, significant risk factors included number of previous treatments (HR, 1.181; p < 0.001), tumour number (HR, 1.943; p = 0.009), and α-feto protein level (HR, 1.005; p = 0.037) in the multivariate analyses. Treatment strategy was not a significant risk factor for recurrence-free survival. For local recurrence-free survival from the date of treatment, only treatment modality (transarterial chemoembolization) (HR, 6.879; p = 0.002) was a significant risk factor. Recurrence-free survival was not significantly different between early treatment and watchful waiting for SHNHRs. (orig.)

    A reevaluation of the clinical value of radioimmunological thyroglobulin (hTg) determination during follow-up of differentiated thyroid carcinoma, in general, confirms our previous results already published in 1980 and 1981. A total of 163 patients with differentiated thyroid carcinoma, 53 with papillary and 110 with follicular carcinoma, was studied up to January 1984. 586 sera are included in this study. The differentiation of suspicious from nonsuspicious findings was found to be based upon a cut-off concentration of 10 μg/l. Pathological findings were associated with hTg concentrations above 20 μg/l. Diagnostic accuracy was calculated to be between 95 and 97%, sensitivity of the method in comparison to be radioiodine whole-body scan was 98 versus 83%, respectively, and specificity 94%. At first 5 false negative and 6 false positive hTg findings have been obtained. 7.6% of the patients demonstrated endogeneous hTg antibodies by Boyden test. 7.7% of Boyden test negative sera showed an unacceptable hTg recovery of worse than +- 50%, which was possibly due to endogeneous antibodies. Again, endogenous TSH was able to stimulate hTg secretion in the form of elevated levels, yet did not affect the clinical diagnosis. Examples of the behaviour of hTg levels during follow-up are demonstrated. Specifically, the cases with false hTg findings are discussed. Basically, the conclusions are the same as in 1980 and 1981: hTg determination is able to replace the routinely performed radioiodine whole-body scan during follow-up, if once residual thyroid tissue and metastases have been excluded by means of radioiodine and an optimal follow-up program is used.

    Urethral carcinoma in 2 females has been treated with irradiation together with adjunct chemotherapy. In case 1, a 73-year-old female with squamous cell carcinoma was successfully treated with irradiation of 4,000 rad and peplomycin of 60 mg intravenously given. She has been free from the disease for the past 43 months. In case 2, a 61-year-old female with transitional cell carcinoma was initially treated with irradiation of 5,000 rad together with peplomycin 90 mg, which was followed by another 5,000 rad irradiation. The tumor recurred and the patient was operated on for cystourethrectomy and partial resection of the vagina. A further chemotherapy of cisplatin, peplomycin, and mitomycin C was instituted. She died of the tumor recurrence 23 months after the first visit to our clinic. Diagnosis and treatment modalities on the female urethral carcinoma are briefly discussed. (author)

    The identification of a marker for early progression of preinvasive lesions into invasive pelvic high-grade serous carcinoma (HGSC) may provide novel handles for innovative screening and prevention strategies. The interplay between cancer cells and the extracellular matrix (ECM) is one of the main principles in cancer development and growth, but has been largely neglected in preinvasive lesions. This is the first study addressing the involvement of the ECM in the "step-by-step" transition of normal fallopian tube epithelium into preinvasive lesions, and eventually the progression of preinvasive lesions into invasive HGSC. The expression of highly sulfated chondroitin sulfate (CS-E), a characteristic glycosaminoglycan of the cancer-associated ECM, was assessed by immunohistochemistry in a large cohort of precursor lesions of the full spectrum of HGSC development, including 97 serous tubal intraepithelial carcinomas (STICs), 27 serous tubal intraepithelial lesions, and 24 p53 signatures. In addition, the immunological reactivity in the microenvironment was evaluated. Increased stromal expression of highly sulfated CS-E was observed in 3.7%, 57.7%, and 90.6% of serous tubal intraepithelial lesions, STICs, and invasive HGSCs, respectively (P STIC, P STIC and paired HGSC was demonstrated. Intense stromal CS-E expression in STIC was significantly associated with an immune infiltrate (P < 0.001). Our study showed that increased stromal CS-E expression is related to the degree of the tubal epithelium abnormality. Specific alterations in the ECM (ie, CS-E expression) occur early in pelvic HGSC development and may represent a novel biomarker of early cancer progression, useful for the identification of novel clinical strategies.

  5. The role of lymphoscintigraphy, sentinel mode biopsy and positron emission tomography in the staging of the neck in early oral squamous cell carcinoma

    Hyde, Nicholas Charles

    This thesis explores the limitations of current imaging modalities in the evaluation of the clinically node negative (N0) neck in early oral squamous cell carcinoma and evaluates the utility of two new interventions. It will become evident that the use of clinical parameters and conventional imaging to detect clinically occult cervical lymph node metastases is an imprecise science. The presence of metastases in the neck is the single most important determinant of survival. Hitherto the lack of timely intervention in this regard may have been contributory in amplifying their effect upon survival. There is an obvious requirement for a more accurate technique to stage the neck in this patient group. Therefore the application of lymphoscintigraphy in combination with sentinel node biopsy (SNB), and positron emission tomography (PET) have been investigated. It appears that PET, whilst having a number of useful roles in the generic head and neck oncology patient, has little to contribute in the diagnosis of occult neck disease. In contra-distinction lymphoscintigraphy and SNB are not only feasible in the diagnosis of occult metastases, but also enhance our knowledge of lymphatic drainage from the oral cavity. This has, in some circumstances, led to the modification of initially prescribed treatment plans. Such is the current pace of technological advance that over the course of this research an entirely new imaging modality has emerged - PET/CT. Whilst it has not been possible to apply this retrospectively to the original patient population early experience of this novel technique in head and neck malignancy is explored and reported. The results of these initial applications are encouraging.

    Full Text Available BACKGROUND Thyroid carcinoma accounts for less than 1% of cancer cases. In the Indian subcontinent, thyroid carcinoma exhibits a varied disease profile and geographic differences in the pattern of cancer, the knowledge of which impacts a more favourable clinical outcome. The present study aims to profile Thyroid carcinoma in areas of age, gender, geographic domicile, morphology & clinical features and referral paradigm of cases in King George Hospital, Visakhapatnam, the tertiary referral hospital for coastal Andhra Pradesh. METHODS & MATERIALS The Retrospective Study 1988-2004 includes 188 patients who attended Department of Nuclear Medicine for pre & postoperative nuclear scan, thyroid carcinoma treatment protocol, whose clinical features, relevant laboratory data, histopathological reports & prognosis were analysed. RESULTS Papillary thyroid carcinoma was present in 79% and Follicular thyroid carcinoma in 19%, Anaplastic & Medullary Thyroid Carcinoma in 2% of cases (n=188, male to female ratio 1:0.62. Coastal city of Visakhapatnam recorded highest 59% of cases who were in their 3rd and 4th decades. West Godavari District had lowest at 5%. Clinical presentation of cases of Thyroid carcinoma as a Nodule (61% which was the most common form lead to maximum number of referrals (n=82 from the Department of Surgery, King George Hospital. CONCLUSION In coastal Andhra Pradesh, papillary thyroid carcinoma was the most dominant form. Women were more affected than men. Painless thyroid nodule was the most common clinical feature. Coastal city of Visakhapatnam recorded highest number of cases and maximum referrals were from Department of Surgery.

    Full Text Available Background. Sweat gland carcinoma is a rare malignancy with a high metastatic potential seen more commonly in elderly patients. The scalp is the most common site of occurrence and it usually spreads to regional lymph nodes. Liver, lungs, and bones are the most common sites of distant metastasis. Late lung metastasis of sweat gland adenocarcinoma after a time span of 5 years is extremely rare. Aim. We report a patient with late lung metastasis of a primary sweat gland carcinoma 10 years after initial surgical resection. Conclusion. Sweat gland carcinomas are rare cancers with a poor prognosis. Surgery in the form of wide local excision and lymph node dissection is the mainstay of treatment. Late pulmonary metastases with a latency of 10 years have never been reported in the literature. This is the first clinical documentation of late lung metastasis from sweat gland carcinoma with a latency period of 10 years.

    The aim of this study was to compare the clinicopathological features of oral squamous cell carcinoma in the background of oral submucous fibrosis (OSCC-OSMF) and oral squamous cell carcinoma (OSCC). A total of 217 cases of OSCC were retrieved from achieves for the analysis. OSCC-OSMF cases were segregated on the basis of history and clinicopathological parameters. The study included 217 patients of which 112 had OSCC and 105 OSCC-OSMF. OSCC-OSMFs were younger compared with OSCC. Overall oral cancer was noted predominantly in males compared to females. The number of OSCC-OSMF was more in clinical TNM stage I and stage II as compared to OSCC, whereas the number of OSCC was more in stage III and stage IV compared to OSCC-OSMF. Histological presentation of well-differentiated squamous cell carcinoma was significantly more in OSCC-OSMF compared to OSCC, whereas moderately differentiated squamous cell carcinoma was significantly more in OSCC compared to OSCC-OSMF. Regional lymph node metastasis was significantly higher in OSCC compared to OSCC-OSMF. Three-year disease-free survival rate was significantly higher in OSCC-OSMF compared to OSCC. The OSCC-OSMF was found to be a clinicopathologically distinct entity with a better grade of tumor differentiation, less incidence of nodal metastases, and early detection (early clinical TNM stage) compared to OSCC. All these factors probably contribute to a better prognosis and increased 3-year disease-free survival in OSCC-OSMF patients. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    The objective of this study was to investigate therapeutic strategies for oropharyngeal squamous cell carcinoma based on an examination of clinical outcomes in our department. The patients were 99 cases with oropharyngeal squamous cell carcinoma treated in our hospital from March 2000 to March 2009. Five-year overall survival (OS) and 5-year cause-specific survival (CSS) were examined by the Kaplan-Meier survival curve. Subsite, stage, treatment (surgery group or radiotherapy or/and chemotherapy group) and prognosis were reviewed retrospectively. Five-year OS and 5-year CSS were 50% and 59%. Compared with the Stage I and II groups, the prognosis of Stage III and IV groups was significantly worse. As for the treatment, 5-year CSS of the surgery group was 76%, while that of the radiotherapy or/and chemotherapy group was 52%. Regarding the subsite, 5-year CSS of the lateral wall type Stage I and II groups was 90% (surgery group: 100%, radiotherapy or/and chemotherapy group: 83%), and that of the Stage III and IV groups was 63% (surgery group: 87%, radiotherapy or/and chemotherapy group: 55%). Five-year CSS of the superior wall type Stage I and II groups was 85% (surgery group: 100%, radiotherapy or/and chemotherapy group: 66%), and that of the Stage III and IV groups was 50% (surgery group: 75%, 5-year CSS was not obtained in the radiotherapy or/and chemotherapy group). The good outcome of the surgery group suggests that the indications for the operation were appropriate, and expansion of transoral resection should be considered in the near future. The outcomes of the radiotherapy or/and chemotherapy group require improvement. (author)

    Fifty-two cases of oral verrucous carcinoma treated with radiotherapy at the Regional Cancer Centre, Trivandrum, Kerala, India in 1982 were evaluated to determine the distribution within the oral cavity, clinical extent, and effectiveness of radiotherapy in controlling the disease. The most common site was the buccal mucosa. Fifty percent of the patients had clinically negative regional lymph nodes and 33% were in earlier stages (T1, T2, N0, and M0). The overall 3-year no evidence of disease (NED) survival rate was 44%. The 3-year NED survival rate with radium implant was 86%. We cannot comment on anaplastic transformation after radiotherapy because our treatment failures have not been subjected for biopsy concerning this matter. Because the results are comparable with those of well-differentiated squamous cell carcinoma, we think that the treatment policies advocated for oral squamous cell carcinoma are also applicable to oral verrucous carcinoma

    The aim of this study was retrospective analysis of male urethral carcinoma to assess the best therapeutic approach to the management of this tumor. A review of 36 cases of male urethral carcinoma diagnosed and treated at our center was performed. Clinical features, treatment modality and outcomes were analysed. The overall median survival time was 55.16 months. The 5-year overall and disease-free survival rate for the cohort was 49% and 23%, respectively. The 5-year survival is 67% for low-stage versus 33% for high-stage tumors and is significantly different (P=0.001). The survival was 72% for tumors of the distal urethra versus 36% for tumors of the proximal, with a P-value of 0.02. The tumor location and clinicopathological stage were the most important predictors of the disease-free and overall survival. Multimodal approach is necessary for achieving local control especially for proximal and higher stage tumors. (author)

    Full Text Available Abstract Background We sought to compare the baseline demographics, standard pathologic factors and long-term clinical outcomes between ILC and infiltrating ductal carcinoma (IDC using a large database. Methods Clinicopathologic features, overall survival (OS, and recurrence/metastasis-free survival (RFS were compared between 2,202 patients with IDC and 215 patients with ILC. Results ILC was significantly more likely to be associated with a favorable phenotype, but the incidence of contralateral breast cancer was higher for ILC patients than for IDC patients (8.4% vs. 3.9%; P =0.001. The frequencies of recurrence/metastasis (P = 0.980 and death (P = 0.064 were similar among patients with IDC and patients with ILC after adjustment for tumor size and nodal status. The median follow-up was 42.8 months. Conclusions Chinese women with ILCs do not have better clinical outcomes than their counterparts with IDC. Management decisions should be based on individual patient and tumor biologic characteristics, and not on lobular histology.

    To compare the usefulness of mammography and clinical examination in the evaluation of residual cancer of locally-advanced breast carcinoma treated with neoadjuvant chemotherapy. Among 67 patients with locally advanced breast carcinoma who were treated with neoadjuvant chemotherapy, 18, aged 35-67 (mean, 48) years, underwent mammography before and after this therapy. The 18 sets of mammographs were analyzed retrospectively and compared with the results of clinical examination based on histologic diagnosis. On histologic examinations, 16 of 18 patients (89%) were found to have residual cancer, but in one of these 16, mammography did not show this same result. On mammography, residual cancer was found in 16 patients, but in one of this group, histologic examination did not reveal the same finding. Clinically, a complete response was shown by four patients, and a partial response by 11 ; three showed no response. On histolgogic examination, three of the four patients with complete clinical response were found to have residual cancer. Post-treatment mammographic findings showed that 11 patients had measurable mass ; all of these had residual cancer (positive predictive value : 100%). However, five of seven patients in whom no measurable mass was evident also had residual cancer. Seven of 8 patients in whom microcalcifications were seen on mammography were found to have residual cancer (positive predictive value : 88%). The sensitivity of mammography in predicting residual cancer was greater than that of clinical examination (94% vs 81%), even when microscopic residual cancer was considered as a complete response (92% vs 77%). The specificity of mammography was the same as that of clinical examination(50% vs 50%, 20% vs 20%). In evaluating residual cancer of locally-advanced breast carcinoma after neoadjuvant chemotheragy, mammography is more accurate and informative than clincal examination. In predicting residual cancer, however, it is not accurate enough to replace

We investigated whether the α-fetoprotein (AFP response is associated with survival in patients with advanced HCC treated with sorafenib. Methods: We retrospectively reviewed the records of 126 patients with advanced HCC treated with sorafenib between 2007 and 2012. An AFP response was defined as >20% decrease from baseline. At 6–8 weeks after commencing sorafenib, AFP and radiological responses were assessed by modified Response Evaluation Criteria in Solid Tumors. Results: The median overall survival (OS and progression-free survival (PFS were 6.2 and 3.5 months, respectively. Of the study population, a partial response (PR was identified in 5 patients (4.0%, stable disease (SD in 65 patients (51.6%, and progressive disease (PD in 57 patients (44.4%, respectively.

    The aim of this retrospective study was to evaluate the contribution of 18 F-FDG PET to the clinical management and survival outcome of patients suspected of recurrent cervical carcinoma and in line with the hypothesis that early diagnosis of recurrent cervical cancer may improve overall survival. A total of 40 patients underwent conventional imaging (CI) and FDG PET/CT for suspected cervical cancer. Clinical management decisions were recorded with CI and additional PET/CT. Discordances and concordances between CI and PET/CT results were compared to the final diagnosis as based on histopathology analysis or follow-up considered as the gold standard. The final diagnosis was established pathologically (n=25) or by median clinical follow-up for 48 months after the PET (n=15). The PET/CT was positive in 76% (20/26) of patients compared to 19% (6/26) with CI. Globally PET/CT modified the treatment plan in 55% (22/40) of patients and in 75% (18/24) when the CI was negative prior to PET/CT. These changes led to the use of previously unplanned therapeutic procedures in 37.5% (15/40). When FDG PET was positive for recurrence (>3 foci), the median overall survival was 12 months (2-70) compared to patients with PET findings with ≤1 focus for which the median survival was not attained (p=0.007). A multivariate analysis of prognostic factors demonstrated that abnormal FDG uptake (>3 foci) was the most significant factor (p<0.03) for death from cervical cancer. FDG PET is a valuable tool in the case of suspected recurrence of cervical cancer on account of its impact on treatment planning and especially in predicting patient outcome. (orig.)

    Nasopharyngeal carcinoma (NPC) is a disease which is prevalent in developing countries like Indonesia. There were 164 new cases of nasopharyngeal carcinoma in the ear, nose, and throat (ENT) oncology outpatient clinic of the Cipto Mangunkusumo hospital in 2014, and 142 cases in 2015. Unfortunately, almost all of these cases presented at an advanced stage. The success of nasopharyngeal carcinoma treatment is largely determined by the stage when patients are diagnosed; it is critical to diagnose NPC as early as possible. Narrow-band imaging (NBI) is an endoscopic instrument with a light system that can improve the visualization of blood vessels of mucosal epithelial malignant tumors. NBI is expected to help clinicians to assess whether a lesion is malignant or not; to do so, it is important to know the value of sensitivity and specificity. This study is a cross-sectional form of a diagnostic test which was performed in the outpatient clinic of the ENT Head and Neck Surgery Department for the Cipto Mangunkusumo Hospital, from January to June 2016, and involved 56 subjects. Patients with a nasopharyngeal mass discovered by physical examination or imaging, and a suspected nasopharyngeal carcinoma were included as a subject. An NBI examination and biopsy was performed locally. Based on this research, NBI could be used as a screening tool for nasopharyngeal carcinoma with high sensitivity (100%), but with a low specificity result (6.7%).

    Mammography has proven to be an effective modality for the detection of early breast carcinoma. However, 4-34 percent of breast cancers may be missed at mammography. Delayed diagnosis of breast carcinoma results in an unfavourable prognosis. The objective of this study was to determine the causes and characteristics of breast carcinomas missed by mammography at our institution, with the aim of reducing the rate of missed carcinoma. We reviewed the reports of 13,191 mammograms performed over a five-year period. Breast Imaging Reporting and Data Systems (BI-RADS) were used for the mammographical assessment, and reports were cross-referenced with the histological diagnosis of breast carcinoma. Causes of missed carcinomas were classified. Of 344 patients who had breast carcinoma and had mammograms done prior to surgery, 18 (5.2 percent) failed to be diagnosed by mammography. Of these, five were caused by dense breast parenchyma obscuring the lesions, 11 were due to perception and interpretation errors, and one each from unusual lesion characteristics and poor positioning. Several factors, including dense breast parenchyma obscuring a lesion, perception error, interpretation error, unusual lesion characteristics, and poor technique or positioning, are possible causes of missed breast cancers.

    Objective: To investigate the incidence of post-irradiation sensorineural hearing loss (SNHL) in patients suffering from nasopharyngeal carcinoma and to evaluate its potentially contributing factors. Methods: Pure tonetest and impedance audiography were carried out in patients suffering from nasopharyngeal carcinoma with a post-irradiation follow-up time over 1 year. Additionally, the test results were combined with clinical data and analyzed retrospectively. Results: The follow-up time of all patients ranged from 12 to 94 months (median 53 months). The incidences of SNHL at low and high frequencies were 8% and 42% respectively. Univariate analysis showed that patient's age and follow-up time affected the incidence of SNHL at high frequencies (t=2.051, P=0.0269; t=2.978, P=0.0011), but sex, preirradiation subjective hearing loss, irradiation dose and chemotherapy including cisplatin had no significance. Multivariate analysis by Binary Logistic Regression revealed that the risk of SNHL was correlated with patient's age and follow-up time (P=0.02; P=0.009). Conclusion: Post-irradiation SNHL at high frequencies in patients suffering from nasopharyngeal carcinoma is more common than that at low frequencies. The independent prognostic factors for development of SNHL at high frequencies are patient's age and follow-up time. But the role of preirradiation hearing level ,irradiation dose and chemotherapy including cisplatin are not conclusive and further research is needed. (authors)

    Hepatic resection is the most curative treatment option for early-stage hepatocellular carcinoma, but is associated with a high recurrence rate, which exceeds 50% at 5 years after surgery. Understanding the genetic basis of hepatocellular carcinoma at surgically curable stages may enable the identification of new molecular biomarkers that accurately identify patients in need of additional early therapeutic interventions. Whole exome sequencing and copy number analysis was performed on 231 hepatocellular carcinomas (72% with hepatitis B viral infection) that were classified as early-stage hepatocellular carcinomas, candidates for surgical resection. Recurrent mutations were validated by Sanger sequencing. Unsupervised genomic analyses identified an association between specific genetic aberrations and postoperative clinical outcomes. Recurrent somatic mutations were identified in nine genes, including TP53, CTNNB1, AXIN1, RPS6KA3, and RB1. Recurrent homozygous deletions in FAM123A, RB1, and CDKN2A, and high-copy amplifications in MYC, RSPO2, CCND1, and FGF19 were detected. Pathway analyses of these genes revealed aberrations in the p53, Wnt, PIK3/Ras, cell cycle, and chromatin remodeling pathways. RB1 mutations were significantly associated with cancer-specific and recurrence-free survival after resection (multivariate P = 0.038 and P = 0.012, respectively). FGF19 amplifications, known to activate Wnt signaling, were mutually exclusive with CTNNB1 and AXIN1 mutations, and significantly associated with cirrhosis (P = 0.017). RB1 mutations can be used as a prognostic molecular biomarker for resectable hepatocellular carcinoma. Further study is required to investigate the potential role of FGF19 amplification in driving hepatocarcinogenesis in patients with liver cirrhosis and to investigate the potential of anti-FGF19 treatment in these patients. © 2014 by the American Association for the Study of Liver Diseases.

    A comparative study with CT and barium enema (BE) was performed on 60 patients (121 lesions) with secondary involvement to the colon from gastric carcinoma. The lesions were visualized as abnormally thick colonic walls (more than 5 mm in thickness) on CT as well as stenotic or striped appearance on BE. The colonic lesions were equally detected by CT and BE in 49 patients (103 lesions). Although CT was superior to BE in only one patient (one lesion), BE was more accurated in 10 patients (17 lesions). CT failed to demonstrate early changes of secondary involvement to the colon. The presence of ascites or mesenteric abnormalities was not detected by CT in 15 patients, even though spread of gastric carcinoma to the colon mainly occurred by the direct invasion along mesenteric reflections or intraperitoneal seeding. As a conclusion, it was found that BE was more accurate for the detection of secondary involvement to the colon from gastric carcinoma comparing to CT. Normal findings on CT did not eliminate the possibility of colonic metastasis, therefore, BE study was desirable if clinical findings suggest the involvement of colonic metastasis. (author)

    To propose a novel clinical typing classification focusing on the distinct progression patterns of nasopharyngeal carcinoma (NPC), to supplement our knowledge of the clinical-biological behavior, to provide useful knowledge for treatment planning, and to contribute to basic research in NPC. 632 consecutive patients were retrospectively reviewed and analyzed according to the novel typing system. We considered that NPC can be divided into 5 types as follows: limited (L), ascending (A), descending (D) ascending- descending (mixed) (AD), and distant metastasis types (M). The distribution of these clinical types, their association with Epstein-Barr virus (EBV) serology and prognostic value were explored. 55 (8.70%), 59 (9.34%), 177 (28.01%), 321 (50.79%) and 20 (3.16%) patients were classified as Type L, A, D, AD and M, respectively. EBV (VCA)-IgA titers, EBV early antigen (EA)-IgA serum titers, and capsid antigen lg(EBV DNA) were positively associated with the clinical typing (pTypes L, A, D, AD and M were 100, 100, 95.10, 88.20 and 59.30%, respectively (ptype, which were independent predictors of OS (multivariate Cox proportional model). The prognostic model stratified patients into 4 risk subgroups. The 3-year OS rates of the low, intermediate, high and extremely high risk groups were 99.5, 90.0, 85.5 and 53.2%, respectively (ptyping system and prognostic model can supplement TNM classification, and may help design novel treatment strategies, evaluate risk stratification and investigate the varied biological characteristics of NPC.

    Full Text Available Clinical defectological diagnostics, related to diagnostics of each individual's impairment of his cognitive and socializing abilities, has been applied in our country for a long time. Since it is a new area in the clinical defectological work and a new form of research in defectology, it poses a series of problems which have not been met so far. We shall to recognize some of them in this paper and to aim at their solution.This time we shall consider only the most prominent problems towards which we direct our interventions:· When does defectological diagnostics take part in diagnosis as treatment of impairments of the handicapped person? When does it function in the process of rehabilitation? For example, is working with a dyslexic child treatment or rehabilitation?· When does the early diagnostics reveal a problem arising from inappropriate intersection of different development courses, which can sometimes be solved without any particular treatment (early stuttering, various convulsions, and when does it reveal actual condition, such as oligophrenia or autism. Thereby we ask ourselves if early stimulative treatment of oligophrenic children or children with early childhood psychosis is treatment or rehabilitation.We tried to classify end explain the problems of diagnostics in the context of treatment and rehabilitation and to define the theoretical grounds for our standpoints.We wanted to point out the unity of the process of any impairment of the handicapped person from early childhood to the end of his life. Treatment and rehabilitation should be a united process and follow the course of development of early disorders which sometimes end up as handicaps, and sometimes, thanks to the treatment, may end up in successful socialization, for example, persons with impaired hearing or sight.We establish defectology as a complete theoretical standpoint and expert procedure which is parallel to and complementary with medicine.

    2014-01-01

    Background The aim of this study was to evaluate the clinical efficacy of submandibular gland transfer for the prevention of xerostomia after radiotherapy for nasopharyngeal carcinoma. Methods Using the randomized controlled clinical research method, 65 patients with nasopharyngeal carcinoma were randomly divided into an experimental group consisting of 32 patients and a control group consisting of 33 patients. The submandibular glands were averted to the submental region in 32 patients with nasopharyngeal carcinoma before they received conventional radiotherapy; a lead block was used to shield the submental region during therapy. Prior to radiotherapy, the function of the submandibular glands was assessed using imaging. Submandibular gland function was measured using 99mTc radionuclide scanning at 60 months after radiotherapy. The data in the questionnaire regarding the degree of xerostomia were investigated and saliva secretion was measured at 3, 6, 12, and 60 months after radiotherapy. In addition, the 5-year survival rate was calculated. Results After follow-up for 3, 6, and 12 months, the incidence of moderate to severe xerostomia was significantly lower in the experimental group than in the control group. The average amount of saliva produced by the experimental and control groups was 1.60 g and 0.68 g, respectively (P xerostomia was significantly lower than in the control group (15.4% and 76.9%, respectively; P xerostomia after radiotherapy for nasopharyngeal carcinoma, we found that clinical efficacy was good. This approach could improve the quality of life of nasopharyngeal carcinoma patients after radiotherapy and would not affect long-term treatment efficacy. PMID:24555575

    Gingival squamous cell carcinoma (GSCC) is an uncommon condition of the oral cavity. It is seldom associated with classic risk factors of oral cancer and shows a predilection for females. It's close clinical resemblances to various lesions of the oral cavity may make it go unnoticed. This may lead to diagnosis at advanced stages and coupled with the proximity to underlying alveolar bone may result in subsequent morbidity and mortality. A case of GSCC camouflaged as an aphthous ulcer in a middle aged woman is presented. The article highlights the importance of early diagnosis resulting in conservative treatment approaches.

    Full Text Available A 77-year-old female, who suffered from rheumatoid arthritis and hypothyroidism, developed severe muscle weakness. Clinical features, blood results and muscle biopsy suggested a possible diagnosis of dermatomyositis. A computed tomography of the chest, abdomen and pelvis showed a solid mass in the left kidney. She underwent a left laparoscopic nephrectomy and histology confirmed conventional (clear cell renal cell carcinoma. She recovered slowly and almost back to normal life after 6 months. Early appreciation of the typical skin rash may provide a clue to the diagnosis and screening for neoplasm may improve prognosis.

    Anal canal carcinoma are highly curable by irradiation, combined with chemotherapy in locally advanced disease, with preservation of sphincter function. The clinical target volume for the nodes is extended, often including the inguinal nodes, which is not usual for other pelvic tumours. Acute and late effects are correlated with the volume and dose delivered to organs at risk, i. e. small bowel, bladder and increased by concomitant chemotherapy. Intensity modulated irradiation (IMRT) makes it possible to optimize the dose distribution in this 'complex U shaped' volume, while maintaining the dose distribution for the target volumes. The conversion from conformal irradiation to IMRT necessitates good knowledge of the definition and skills to delineate target volumes and organs at risk, including new volumes needed to optimize the dose distribution. Dosimetric and clinical benefits of IMRT are described, based on early descriptions and evidence-based publication. The growing development of IMRT in anal canal radiotherapy must be encouraged, and long-term benefits should be soon published. Radiation oncologists should precisely learn IMRT recommendations before starting the technique, and evaluate its early and late results for adverse effects, but also for long-term tumour control.

    Cigarette smoking is a common risk factor for developing nasopharyngeal carcinoma. However, the relationship between smoking and clinical outcomes remains uncertain. The patients who participated in this study were drawn from a randomized clinical trial, for which the purpose was to compare the efficacy of induction chemotherapy plus concurrent chemoradiotherapy with that of induction chemotherapy plus radiotherapy in patients with locoregionally advanced nasopharyngeal carcinoma. The patients who ever smoked were divided into the following categories of cumulative smoking exposure based on the duration of smoking and the quantity of cigarettes smoked: light, short-term smokers; light, long-term smokers; heavy, short-term smokers; and heavy, long-term smokers. A log-rank test and Cox models were used to assess the association between smoking and the clinical outcomes of overall survival (OS), failure-free survival (FFS), locoregional recurrence failure-free survival (LRFFS) and distant failure-free survival (DFFS). We found that ever-smokers experienced significantly shorter LRFFS times than never-smokers (5-year LRFFS rates: 85.8% vs. 88.5%, P = 0.022). The amount of smoking was significantly associated with FFS (P = 0.046) and LRFFS (P = 0.001) in the different ever-smoker groups. The amount of smoking was associated with LRFFS [P = 0.002, HR = 2.069 (95% confident interval (CI), 1.298-3.299)] even after a multivariable adjustment. Smoking increases the risk of locoregional recurrence. Furthermore, the amount of smoking influences the prognosis of smokers, and these effects are dose-dependent

    Red dot basal cell carcinoma is a unique variant of basal cell carcinoma. Including the three patients described in this report, red dot basal cell carcinoma has only been described in seven individuals. This paper describes the features of two males and one female with red dot basal cell carcinoma and reviews the characteristics of other patients with this clinical subtype of basal cell carcinoma. A 70-year-old male developed a pearly-colored papule with a red dot in the center on his nasal tip. A 71-year-old male developed a red dot surrounded by a flesh-colored papule on his left nostril. Lastly, a 74-year-old female developed a red dot within an area of erythema on her left mid back. Biopsy of the lesions all showed nodular and/or superficial basal cell carcinoma. Correlation of the clinical presentation and pathology established the diagnosis of red dot basal cell carcinoma. The tumors were treated by excision using the Mohs surgical technique. Pubmed was searched with the keyword: basal, cell, cancer, carcinoma, dot, red, and skin. The papers generated by the search and their references were reviewed. Red dot basal cell carcinoma has been described in three females and two males; the gender was not reported in two patients. The tumor was located on the nose (five patients), back (one patient) and thigh (one patient). Cancer presented as a solitary small red macule or papule; often, the carcinoma was surrounded by erythema or a flesh-colored papule. Although basal cell carcinomas usually do not blanch after a glass microscope slide is pressed against them, the red dot basal cell carcinoma blanched after diascopy in two of the patients, resulting in a delay of diagnosis in one of these individuals. Dermoscopy may be a useful non-invasive modality for evaluating skin lesions when the diagnosis of red dot basal cell carcinoma is considered. Mohs surgery is the treatment of choice; in some of the patients, the ratio of the area of the postoperative wound to that

    The clinical outcomes and therapeutic strategies for infiltrating ductal carcinoma (IDC) and infiltrating lobular carcinoma (ILC) are not uniform. The primary objectives of this study were to identify the differences in the clinical characteristics and prognoses between ILC and IDC, and identify the high-risk population based on the hormone receptor status and metastasis sites. The Surveillance, Epidemiology, and End Results Program database was searched and patients diagnosed with ILC or IDC from 1990 to 2013 were identified. In total,796,335 patients were analyzed, including 85,048 withILC (10.7%) and 711,287 withIDC (89.3%). The ILC group was correlatedwith older age, larger tumor size, later stage, lower grade, metastasis disease(M1) disease, and greater counts ofpositive lymph nodesandestrogen-receptor-positive (ER)/progesterone receptor-positive (PR) positive nodes. The overall survival showed an early advantage for ILC but a worse outcome after 5 years. Regarding the disease-specific survival, the IDC cohort had advantages over the ILC group, both during the early years and long-term. In hormone status and metastasis site subgroup analyses, the ER+/PR+ subgroup had the best survival, while the ER+/PR- subgroup had the worst outcome, especially the ILC cohort. ILC and IDC had different metastasis patterns. The proportion of bone metastasis was higher in the ILC group (91.52%) than that in the IDC (76.04%), and the ILC group was more likely to have multiple metastasis sites. Survival analyses showed patients with ILC had a higher risk of liver metastasis (disease-specific survival[DSS]; P = 0.046), but had a better overall survival than the bone metastasis group (P<0.0001). We concluded that the long-term prognosis for ILC was poorer than that for IDC, and the ER+/PR- subgroup had the worst outcome. Therefore, the metastasis pattern and prognosis must be seriously evaluated, and a combination of endocrine therapy and chemotherapy should be considered. PMID

    2014-11-01

    Recent years have brought an enhanced understanding of Merkel cell carcinoma (MCC) biology, especially with regard to the Merkel cell polyoma virus as a causative agent. Differences between Merkel cell polyomavirus-positive and Merkel cell polyomavirus-negative MCC in morphology; gene expression, miRNA profiles and prognosis have been reported. Origin of MCC is controversial. Presence of neurosecretory granules has suggested that these carcinomas originate from one of the neurocrest derivatives, most probably Merkel cells; the name Merkel cell carcinoma is now widely accepted. Expression of PGP 9.5, chromogranin A and several neuropeptides, initially regarded as specific markers for neural and neuroendocrine cells, has recently been shown in a subset of lymphomas. MCC commonly expresses terminal deoxynucleotidyl transferase and PAX5. Their co-expression under physiologic circumstances is restricted to pro/pre-B cells and pre-B cells. These findings lead to the hypothesis by zur Hausen et al. that MCC originates from early B cells. This review was intended to critically appraise zur Hausen's hypothesis and discuss the possibility that MCC is a heterogenous entity with distinct subtypes. © 2014 John Wiley & Sons A/S.

    Objective: To assess the clinical value of transarterial infusion chemotherapy combined with high intensity focused ultrasound (HIFU) for the treatment of pancreatic carcinomas. Methods: A total of 64 patients with inoperable pancreatic carcinomas were randomly divided into study group (n=32) and control group (n=32). Transarterial infusion chemotherapy combined with HIFU was employed in patients of study group, while simple transarterial infusion chemotherapy was conducted in patients of control group. The effective rate, the clinical benefit rate (CBR), the occurrence of side effect and the survival time of the two groups were recorded. The results were compared between the two groups. Results: The effective rate (PR + MR), the median survival time and the one-year survival rate of the study group were 55.56%, 13.0 months and 68.75% respectively, while the effective rate (PR + MR), the median survival time and the one-year survival rate of the control group were 28.57%, 9.0 months and 43.75% respectively. Both the effective rate and the one-year survival rate of the study group were significantly higher than those of the control group (P<0.05). Conclusion: Compared with pure transarterial infusion chemotherapy, transarterial infusion chemotherapy combined with HIFU can significantly improve the short-term efficacy and increase the one-year survival rate for patients with advanced pancreatic carcinomas.

    The purpose of this study is to investigate the effective of alternating Chemo-radiotherapy for locally Advanced Nasopharyngeal Carcinoma. Retrospective analysis 106 cases of patients with locally advanced nasopharyngeal carcinoma between November 2005 and March 2007. All patients received cisplatin-based chemotherapy but 15 patients received radiotherapy(RT) alone. Inducing chemotherapy (IC) + RT + adju-vant chemotherapy (AC) regimen in 36 patients, IC+RT regimen was delivered in 25 patients and AC + RT regimen in 30 patients. 61 patients received 1 to 2 cycles of inducing chemotherapy and 66 patients received 3 to 6 cycles of adjuvant chemotherapy after radiotherapy. Chemotherapy started on the first day after the end of the induction chemotherapy, adjuvant chemotherapy begun after radiotherapy for a week. All patients were treated by radiotherapy using 60 Co r-ray, the nasophyarynx primary site was given a total does of 68 -74 Gy. The lymph nodes of the neck was given 60 to 70 Gy. The prophylactic irradiation does of the neck was 48-50 Gy. RESCULT: The median follow up time was 51 months. A total of 58 patients died, the overall survival rate was 45% in whole groups. The 5-year overall survival rates were 33%, 63%, 60% and 50% in RT, IC + RT + AC, IC + RT and RT+AC group, respectively. The 5-year disease-free survival rates were 13%, 56%, 48% and 40% in RT, IC + RT + AC, IC + RT and RT + AC group, respectively. The 5-year relapse-free survival rates were 13%, 53%, 48% and 50% in RT, IC + RT + AC, IC + RT and RT + AC group, respectively. The 5-year metastasis-free survival rates were 6%, 50%, 44% and 47% in RT, IC + RT + AC, IC+ RT and RT + AC group, respectively. There was significant difference in all groups (P 0.05). IC + RT + AC group had heavier acute toxicity effects than other groups, but it did not affect the treatment process, all patients could be tolerated. This retrospective study has demonstrated that alternating Chemo-radiotherapy and early

    Thyroid gland carcinomas usually appear as afunctional and hypofunctional lesions on thyroid scintigrams, but some rare cases of thyroid carcinoma with scintigraphic hyperfunctional lesions have also been reported. The aim of our retrospective study was to elucidate the frequency of carcinomas in patients operated for solitary hyperfunctional thyroid nodules and to represent their demographic and clinical features. During one decade (1997/2006), 308 patients were operated for solitary hyperfunctional thyroid nodules in the Centre for Endocrine Surgery in Belgrade. Malignancy was revealed in 9 cases (about 3 %) by histopathological examination. In 6 cases papillary microcarcinomas were found adjacent to dominant hyperfunctional adenomas, while in 3 cases (about 1 %) real hyperfunctional carcinomas were confirmed. Follicular carcinoma was diagnosed in 2 cases and papillary carcinoma in one. All 3 patients were preoperatively hyperthyroid. In both patients with follicular carcinoma we performed lobectomies. In the third case we carried out a total thyroidectomy considering the intraoperative frozen section finding of a papillary carcinoma. According to our results the frequency of solitary hyperfunctioning thyroid carcinomas is about 1 %, so that the possibility that a hyperfunctional nodule is malignant should be considered in the treatment of such lesions. © Georg Thieme Verlag KG Stuttgart ˙ New York.

    Objective: To evaluate the value of lymphoscintigraphy for cervical sentinel lymph node (SLN) detection in patients with oral squamous cell carcinoma. Methods: Twenty-one patients with clinically N 0 oral squamous carcinoma underwent preoperative lymphoscintigraphy and intraoperative methylene blue location. The results were compared with pathological findings. Results: 1) The sensitivity of lymphoscintigraphy for detecting SLN was 100%(21/21), and methylene blue was 85% (17/20). 2)Both SLN biopsy and cervical ablative dissection confirmed that 33.3% (7/21) patients were with cervical lymph node metastasis. Fourteen non-metastatic SLNs comfirmed by biopsy were also proved with the findings of neck dissection, and the specificity was 100%. Conclusion: Lymphoscintigraphy can detect the cervical SLN and accurately predict cervical lymph node metastasis in patients with oral squamous cell carcinoma.(authors)

    Full Text Available ObjectiveTo investigate the value of combined detection of serum alpha-fetoprotein (AFP and Golgi protein-73 (GP73 in the diagnosis of hepatocellular carcinoma (HCC and to provide a basis for early diagnosis and differential diagnosis of HCC. MethodsA total of 408 patients hospitalized in Baoji Central Hospital from June 2012 to May 2013, as well as healthy persons who had normal test results in physical examination, were included in the study, and their specimens were collected. These patients were classified into HCC group (n=142, chronic hepatitis group (n=156, and liver cirrhosis group (n=110. Serum levels of AFP and GP73 in the three groups were measured by electrochemiluminescence immunoassay and double-antibody sandwich enzyme-linked immunosorbent assay, respectively. Comparison of test results between groups was made by analysis of variance, and comparison of rates was made by chi-square test. The sensitivity and specificity of the two indicators for the diagnosis of HCC were calculated using MedCalc statistical software. ResultsThe HCC group had significantly higher serum AFP and GP73 levels than the liver cirrhosis group and chronic hepatitis group (P<0.05; the liver cirrhosis group had significantly higher serum AFP and GP73 levels than the chronic hepatitis group (P<0.05. The sensitivity and specificity of the two indicators for the diagnosis of HCC were 95.8% and 98.6%, respectively, showing significant differences compared with those of each indicator alone (P<0.05. ConclusionCombined detection of serum AFP and GP73 has high diagnostic value and clinical significance for HCC, and they can be used as indicators for early diagnosis and differential diagnosis of HCC.

    Lymphoepithelial carcinoma is an undifferentiated nasopharyngeal carcinoma with lymphoid stroma and non-keratinizing squamous cells with distinctive clinical, epidemiological and etiological features. Conversely, lymphoepithelioma-like carcinomas (LELCs) are carcinomas that arise outside the nasopharynx but resemble a lymphoepithelioma histologically. In this case study, LELC presentation in connective tissue (left sternocleidomastoid muscle) is peculiar and unusual, but its diagnosis is supp...

    Oral cancer is an important health issue. The WHO predicts a continuing worldwide increase in the number of patients with oral cancer, extending this trend well into the next several decades. In the US the projected number of new cases of oral and oropharyngeal cancer will exceed 31,000 per year. Mortality due to cancers in this region exceeds the annual death rate is the US caused by either cutaneous melanoma or cervical cancer. Significant agents involved in the etiology of oral cancer in Western countries include sunlight exposure, smoking and alcohol consumption. Use of the areca or betel nut in many cultures is a major etiological factor outside of the USA. Other etiologic factors associated with oral squamous cell carcinoma, but far less significant statistically, include syphilis and sideropenic dysphagia. Recently, strong evidence for an etiological relationship between human papilloma virus and a subset of head and neck cancers has been noted. It is generally accepted that most sporadic tumors are the result of a multi-step process of accumulated genetic alterations. These alterations affect epithelial cell behavior by way of loss of chromosomal heterozygosity which in turn leads to a series of events progressing to the ultimate stage of invasive squamous cell carcinoma. The corresponding genetic alterations are reflected in clinical and microscopic pathology from hyperplasia through invasiveness. A wide range of mucosal alternations fall within the rubric of leukoplakia. Proliferative verrucous leukoplakia represents a relatively new type of leukoplakia that is separate from the more common or less innocuous form of this condition. Erythroplakia is particularly relevant considering its almost certain relationship with dysplasia or invasive carcinoma. Squamous cell carcinoma will develop from antecedent dysplastic oral mucosal lesions if an early diagnosis has not been made and treatment given. Early diagnosis within stages I and II correspond to a vastly

    The purpose of this study is to evaluate the benefits of mammography in general and particularly as a screening method in the early detection of breast cancer in our hospital. All the cases of breast carcinoma registered in our section between 1989 and 1995 were reviewed retrospectively. The total number of carcinomas was 775, 168 (22%) of which were diagnosed solely on the basis of mammography. The percentage of carcinomas detected on the basis of mammography alone increased progressively (from 13% in 1989-1990 to 28% in 1994-1995), coinciding with a progressive rise in the volume of screening mammography. Early carcinomas, referring to those in stages O or I, represented 67% of those detected by mammography in general and 17% of those detected by palpation (p<0.001). The proportion was even greater among cases of carcinoma detected exclusively by screening mammography (78 versus 17%; p<0.001). Although mammography has been instrumental in increasing the rate of early detection of breast carcinoma in our center, a large number of patients still present with palpable lesions. Thus, a greater effort should be made to increase the practice of mammography in asymptomatic women. (Author) 13 refs

    Metastases to the base of the skull and occipital condyle metastases are uncommon as a presenting feature of malignancy. Lung cancers are known for their metastatic potential to various sites, some of which could be the only presenting feature of the underlying malignancy. However, occipital condyle metastases are very rare and to the best of our knowledge, metastases to this site from carcinoma of the lung, as a presenting feature, have never been reported in the literature. The present case report describes the clinical, radiological and the therapeutic interventions that were undertaken in a patient presenting with lung cancer who had solely the features of occipital condyle metastasis

    Gorlin-Goltz syndrome or nevoid basal cell carcinoma syndrome is a rare hereditary autosomal-dominant disorder characterized by multiple basal cell carcinomas in young patients, odontogenic keratocysts, palmar or plantar pits, calcification of the falx cerebri and skeletal malformations. This syndrome is due to mutations in PTCH1 (patched homolog 1 da Drosophila), a tumor suppressor gene. Diagnostic criteria were defined by Evans, revised by Kimonis and include major and minor criteria. The authors review in particular the neuroradiological and maxillofacial characteristics of the syndrome. The authors describe the clinical presentation of two children with Gorlin-Goltz syndrome without affected first degree relatives. In both the clinical suspicion of the syndrome is raised by the presence of multiple odontogenic cysts surgically removed. Histopathological exam revealed keratocysts. None of the patients has basal cell carcinomas but both present with skeletal anomalies, namely marked pectus deformity. The absence of major diagnostic criteria like basal cell carcinomas or palmar or plantar pits in young patients delay the early diagnosis and the correct screening for medulloblastoma, basal cell carcinomas and cardiac fibromas. Odontogenic keratocysts are the most consistent clinical finding in Gorlin-Goltz syndrome in the first one or two decades of life. These patients are very sensitive to ionizing radiation, being able to develop basal cell carcinomas and meningiomas. Treatment should accomplish the complete resection of the tumors.

    Objective: To evaluate clinical therapeutic efficacy and adverse efficacy of transcatheter arterial chemoembolization (TACE) combined with radiofrequency capacitive heating (RCH) for metastatic hepatic carcinoma (MHC). Methods: Thirty-nine cases of MHC were enrolled in this study and divided into two groups: study group (n=19) and control group (n=20). Before therapy, the Karnofsky's score of the patients was all beyond 60. Results: The carcinoma growth rate of the study group was -(0.38±0.22), while that of the control group was -(0.13±0.25), showing significant statistical difference (P 0.05). Conclusion: The therapeutic effect of MHC can be further improved by the treatment of TACE combined with radiofrequency capacitive heating without increase of adverse side effects. (authors)

    Low-grade salivary duct carcinoma (LG-SDC) is a rare neoplasm characterized by predominant intraductal growth, luminal ductal phenotype, bland microscopic features, and favorable clinical behavior with an appearance reminiscent of florid to atypical ductal hyperplasia to low grade intraductal breast carcinoma. LG-SDC is composed of multiple cysts, cribriform architecture with "Roman Bridges", "pseudocribriform" proliferations with floppy fenestrations or irregular slits, micropapillae with epithelial tufts, fibrovascular cores, and solid areas. Most of the tumor cells are small to medium sized with pale eosinophilic cytoplasm, and round to oval nuclei, which may contain finely dispersed or dark condensed chromatin. Foci of intermediate to high grade atypia, and invasive carcinoma or micro-invasion have been reported in up to 23 % of cases. The neoplastic cells have a ductal phenotype with coexpression of keratins and S100 protein and are surrounded by a layer of myoepithelial cells in non-invasive cases. The main differential diagnosis of LG-SDC includes cystadenoma, cystadenocarcinoma, sclerosing polycystic adenosis, salivary duct carcinoma in situ/high-grade intraductal carcinoma, and papillary-cystic variant of acinic cell carcinoma. There is no published data supporting the continuous classification of LG-SDC as a variant of cystadenocarcinoma. Given that most LG-SDC are non-invasive neoplasms; the terms "cribriform cystadenocarcinoma" and LG-SDC should be replaced by "low-grade intraductal carcinoma" (LG-IDC) of salivary gland or "low-grade intraductal carcinoma with areas of invasive carcinoma" in those cases with evidence of invasive carcinoma.

    Circumscribe breast cancer is a well demarcated mass with or without a lobulated border simulating a benign tumor like fibroadenoma on mammography or breast US and is reported as approximate 10% of the incidence among primary breast carcinoma(1.2). Pathologically medullary, colloid, papillary, intraductal and rarely invasive ductal carcinomas are included in this group which show the less intense desmoplastic reaction than the scirrhous type cancer, resulting in the most favorable prognosis of all carcinoma of the breast. Among 214 primary breast carcinoma during the past 8 years, we experienced 6 case of pathologically proven circumscribed breast cancer(2 cases of medullary carcinoma, 1 of colloid carcinoma, 1 of intracystic papillary carcinoma, 2 of comedo type intraductal carcinoma). Clinically 2 cases showed bloody nipple discharge from one hole of a unilateral nipple orifice. Mammography showed a well circumscribed nodule with or without partial lobular contour and no pathologic calcification. Breast sonographic findings were a well defined heterogeneous hypoechoic nodule with weak posterior acoustic enhancement. Characteristically a thin dilated lactiferous duct between the mass and the nipple on US could be detected in 2 cases which clinically was accompanied by bloody nipple discharge. Although the mammographic criteria is promising as benign tumor, the possibility of circumscribed as benign tumor, the possibility of circumscribed breast carcinoma must be considered in heterogeneous hypoechoic nodule with weak posterior acoustic enhancement in US, especially in the presence of a dilated lactiferous duct between the mass and the nipple with bloody nipple discharge.

    Fanconi anemia is a recessively inherited disease that is characterized by congenital abnormalities, bone marrow failure, and a predisposition to develop cancer, particularly squamous cell carcinomas (SCCs) in the head and neck and anogenital regions. Previous studies of Fanconi anemia SCCs, mainly from US patients, revealed the presence of high-risk human papillomavirus (HPV) DNA in 21 (84%) of 25 tumors analyzed. We examined a panel of 21 SCCs mainly from European Fanconi anemia patients (n = 19 FA patients; 16 head and neck squamous cell carcinomas [HNSCCs], 2 esophageal SCCs, and 3 anogenital SCCs) for their clinical and molecular characteristics, including patterns of allelic loss, TP53 mutations, and the presence of HPV DNA by GP5+/6+ polymerase chain reaction. HPV DNA was detected in only two (10%) of 21 tumors (both anogenital SCCs) but in none of the 16 HNSCCs. Of the 18 tumors analyzed, 10 contained a TP53 mutation. The patterns of allelic loss were comparable to those generally found in sporadic SCCs. Our data show that HPV does not play a major role in squamous cell carcinogenesis in this cohort of Fanconi anemia patients and that the Fanconi anemia SCCs are genetically similar to sporadic SCCs despite having a different etiology.

    Objective: To determine the frequency of submandibular gland involvement in early oral cavity tumors. Study Design: Observational study. Place and Duration of Study: ENT Department, CMH, Rawalpindi, from January 2008 to December 2011. Methodology: Data of 110 oral cavity tumors operated over 2008 - 2011 was retrieved from ENT OPD, tumor registry in AFIP and from Head and Neck Oncology Forum Registry. Cases of oral cavity tumors that had undergone elective neck dissections were retrospectively studied for invasion of the submandibular gland, TNM Staging, perineural, perivascular, lymphovascular invasion, site specific frequency of oral cavity tumors and frequency of lymph node metastasis. Results: Tumors of tongue were the most common constituting 42%, squamous cell carcinoma was the histological diagnosis in 90% cases. Sixty eight (61.8%) cases were node negative. Selective neck dissection was done in 55.5% of the cases. Submandibular gland was involved in 2 cases (1.8%). Conclusion: Submandibular gland metastasis from early oral cavity tumors is rare; any neoplastic involvement of the gland usually occurs via direct spread. (author)

    Most early adnexal carcinomas detected in asymptomatic women with germline BRCA mutations (BRCA) present as serous tubal intraepithelial carcinomas (STIC). However, STICs are found in only ∼40% of symptomatic high-grade serous carcinomas (HGSCs) and less frequently in pseudoendometrioid variants of HGSC. Consecutive cases of untreated HGSC from BRCA and BRCA women with detailed fallopian tube examination (SEE-FIM protocol) were compared. STIC status (+/-) was determined, and tumors were classified morphologically as SET ("SET", >50% solid, pseudoendometrioid, or transitional) or classic predominate ("Classic"). SET tumors trended toward a higher frequency in BRCA versus BRCA women (50% vs. 28%, P=0.11), had a significantly younger mean age than those with classic HGSC in BRCA women (mean 56.2 vs. 64.8 y, P=0.04), and displayed a better clinical outcome in both groups combined (P=0.024). STIC was significantly more frequent in tumors from the BRCA cohort (66% vs. 31%, P=0.017) and specifically the BRCA tumors with classic morphology (83%) versus those with SET morphology (22%, P=0.003). Overall, several covariables-histology, BRCA status, age, coexisting STIC, and response to therapy-define 2 categories of HGSC with differences in precursor (STIC) frequency, morphology, and outcome. We introduce a dualistic HGSC model that could shed light on the differences in frequency of STIC between symptomatic and asymptomatic women with HGSC. This model emphasizes the need for further study of HGSC precursors to determine their relevance to the prevention of this lethal malignancy.

    Objective: The main aim of this barium enema study was to evaluate its role in patients suspected to have rectal pathologies with complaints of change in bowel habit, anorexia/weight loss, bleeding per rectum and acute/sub-acute colonic obstruction. Results: barium enema study as screening test for colo-rectal carcinoma was undertaken. Contrast outlined the colonic growth in 35 cases, out of which the cases of carcinoma colon were 24 including 13 patients suffering from carcinoma rectum. The percentage of carcinoma colon to total colonic growth was 68% while, carcinoma rectum to total carcinoma colon was 54%. Conclusion: On the basis of these investigations, it is concluded that patient's compliance is important factor in the early detection of colonic neoplasia. Though results of colonoscopy are more reliable but in practice, barium enema (double contrast) is performed initially to outline the lesion and then colonoscopy for biopsy purpose. (author)

    The p53 tumor suppressor gene is commonly mutated in colorectal cancer. While the effect of p53 mutations on colorectal cancer prognosis has been heavily studied, less is known about how epidemiologic risk factors relate to p53 status, particularly in early colorectal neoplasia prior to clinically invasive colorectal cancer (including adenomas, carcinoma in situ (CIS), and intramucosal carcinoma). We examined p53 status, as measured by protein overexpression, in 157 cases with early colorectal neoplasia selected from three New York City colonoscopy clinics. After collecting paraffin-embedded tissue blocks, immunohistochemistry was performed using an anti-p53 monoclonal mouse IgG 2 a [BP53-12-1] antibody. We analyzed whether p53 status was different for risk factors for colorectal neoplasia relative to a polyp-free control group (n = 508). p53 overexpression was found in 10.3%, 21.7%, and 34.9%, of adenomatous polyps, CIS, and intramucosal cases, respectively. Over 90% of the tumors with p53 overexpression were located in the distal colon and rectum. Heavy cigarette smoking (30+ years) was associated with cases not overexpressing p53 (OR = 1.8, 95% CI = 1.1–2.9) but not with those cases overexpressing p53 (OR = 1.0, 95% CI = 0.4–2.6). Heavy beer consumption (8+ bottles per week) was associated with cases overexpressing p53 (OR = 4.0, 95% CI = 1.3–12.0) but not with cases without p53 overexpression (OR = 1.6, 95% CI = 0.7–3.7). Our findings that p53 overexpression in early colorectal neoplasia may be positively associated with alcohol intake and inversely associated with cigarette smoking are consistent with those of several studies of p53 expression and invasive cancer, and suggest that there may be relationships of smoking and alcohol with p53 early in the adenoma to carcinoma sequence

    2012-01-01

    Full Text Available Ductal Carcinoma in situ has been diagnosed more frequently in the last few years and now accounts for approximately one-fourth of all treated breast cancers. Traditionally, this disease has been treated with total mastectomy, but conservative surgery has become increasingly used in the absence of unfavourable clinical conditions, if a negative excision margin can be achieved. It is controversial whether subgroups of patients with favourable in situ tumors could be managed by conservative surgery alone, without radiation. As the disease is diagnosed more frequently in younger patients, these issues are very relevant, and much research has focused on this topic in the last two decades. We reviewed randomized trials regarding adjuvant radiation after breast-conservative surgery and compared data with available retrospective studies.

    Chronic fibrotic liver diseases such as viral hepatitis eventually develop liver cirrhosis, which causes occurrence of hepatocellular carcinoma (HCC). Given the limited therapeutic efficacy in advanced HCC, prevention of HCC development could be an effective strategy for improving patient prognosis. However, there is still no established therapy to meet the goal. Studies have elucidated a wide variety of molecular mechanisms and signaling pathways involved in HCC development. Genetically-engineered or chemically-treated experimental models of cirrhosis and HCC have been developed and shown their potential value in investigating molecular therapeutic targets and diagnostic biomarkers for HCC prevention. In this review, we overview potential targets of prevention and currently available experimental models, and discuss strategies to translate the findings into clinical practice. PMID:22873223

    Full Text Available Yingming Zhu,* Minghuan Li,* Li Kong, Jinming Yu Department of Radiation Oncology, Shandong Cancer Hospital and Institute, Shandong University, Jinan, Shandong, People’s Republic of China *These authors contributed equally to this work Abstract: Esophageal cancer is the sixth leading cause of cancer death worldwide, and patients who are treated with surgery alone, without neoadjuvant therapies, experience frequent relapses. Whether postoperative therapies could reduce the recurrence or improve overall survival is still controversial for these patients. The purpose of our review is to figure out the value of postoperative adjuvant therapy and address the disputes about target volume delineation according to published data. Based on the evidence of increased morbidity and disadvantages on patient survival caused by postoperative chemotherapy or radiotherapy (RT alone provided by studies in the early 1990s, the use of postoperative adjuvant therapies in cases of esophageal squamous cell carcinoma has diminished substantially and has been replaced gradually by neoadjuvant chemoradiation. With advances in surgery and RT, accumulating evidence has recently rekindled interest in the delivery of postoperative RT or chemoradiotherapy in patients with stage T3/T4 or N1 (lymph node positive carcinomas after radical surgery. However, due to complications with the standard radiation field, a nonconforming modified field has been adopted in most studies. Therefore, we analyze different field applications and provide suggestions on the optimization of the radiation field based on the major sites of relapse and the surgical non-clearance area. For upper and middle thoracic esophageal carcinomas, the bilateral supraclavicular and superior mediastinal areas remain common sites of recurrence and should be encompassed within the clinical target volume. In contrast, a consensus has yet to be reached regarding lower thoracic esophageal carcinomas; the

    Verrucous carcinoma (also known as Ackerman tumor) is an uncommon exophytic low-grade well-differentiated variant of squamous cell carcinoma. This neoplasm typically involves the oral cavity, larynx, genitalia, skin, and esophagus. It is well known for its locally aggressiveness and for its clinically slow-growing behaviour with minimal metastatic potential. Verrucous carcinoma of oral cavity is so closely aligned with the use of snuff and chewing tobacco that it has been called the"snuff dippers cancer"Recent studies have proved the role of HPV. The typical clinical presentation of oral verrucous carcinoma has long been known, as its remarkably innocuous appearance and biological behaviour. In this work, we report a review of the scientific literature and describe a troublesome case of oral verrucous cancer.

    Purpose: Permanent breast seed implant is an accelerated partial breast irradiation technique realizing the insertion of "1"0"3Pd seeds in the seroma after lumpectomy. We report the 5-year efficacy and tolerance for a cohort, pooling patients from 3 clinical trials. Methods and Materials: The trials accrued postmenopausal patients with infiltrating ductal carcinoma or ductal carcinoma in situ ≤3 cm and clear surgical margins, who were node negative, and had a planning target volume <120 cm"3. The outcomes included overall and disease-free survival and local and contralateral recurrence at 5 years. The true local recurrence rate was compared using 2-tailed paired t tests for estimates calculated using the Tufts University ipsilateral breast tumor recurrence and Memorial Sloan Kettering ductal carcinoma in situ nomograms. Results: The cohort included 134 patients, and the observed local recurrence rate at a median follow-up period of 63 months was 1.2% ± 1.2%, similar to the estimate for whole breast irradiation (P=.23), significantly better than for surgery alone (relative risk 0.27; P<.001), and significantly lower than contralateral recurrence (relative risk 0.33; P<.001). The 5-year overall survival rate was 97.4% ± 1.9%, and the disease-free survival rate was 96.4% ± 2.1%. At 2 months, 42% of the patients had erythema, 20% induration, and 16% moist desquamation. The rate of mainly grade 1 telangiectasia was 22.4% at 2 years and 24% at 5 years. The rate of asymptomatic induration was 23% at 2 years and 40% at 5 years. Conclusions: The 5-year data suggest that permanent breast seed implantation is a safe accelerated partial breast irradiation option after lumpectomy for early-stage breast cancer with a tolerance profile similar to that of whole breast irradiation.

    One hundred and seven cases of oral verrucous carcinoma treated with radiotherapy at Kasturba Hospital, Manipal, India between 1977 and 1987 were analysed concerning location within the oral cavity, clinical extent, and effectiveness of radiotherapy. The most common site was the buccal mucosa followed by the buccogingival sulcus. Only 13.2% of the patients presented with T1 or T2 tumours and 32.7% had clinically negative nodes. Biopsy had to be repeated more than once in 22 patients to get confirmation in invasive carcinoma. The 5-year survival rate was 35% for stage III and 26% for stage IV. The treatment results with radiotherapy were comparable with those for ordinary squamous cell carcinoma of the oral cavity. It is felt that the treatment policy for verrucous carcinoma can be the same as for ordinary squamous cell carcinoma. In order to prevent delay in diagnosis and treatment, proper cooperation between the treating oncologist and the pathologist is essential. (orig.)

    Extensive debulking is accepted as the primary method of operative management for carcinoma of the ovary. However, there is no consensus regarding the role of appendectomy in primary surgical treatment. The aim of this study was to assess the role of appendectomy in the surgical staging and cytoreduction of ovarian carcinoma. The study was a retrospective review of 90 primary malignant ovarian carcinoma patients who had an appendectomy in addition to primary cytoreductive surgery. Out of 90 patients, 10 (11.1%) had metastasis to the appendix. The rate of metastasis to the appendix was 11.5% (9/78) in malignant epithelial ovarian carcinomas and 8.3% (1/12) in non-epithelial ovarian tumors. Of the patients with metastasis in the appendix, malignant epithelial ovarian tumors were identified in 90% (serous: 70%; clear cell: 20%), and non-epithelial malignant ovarian tumor were disclosed in 10% (granulosa cell carcinoma). There were no metastases to the appendix in the other histological types. Although metastasis to the appendix was not observed in early stage ovarian carcinomas, it was detected in 21.4% (9/42) of stage III and 50% (1/2) of stage IV. Macroscopic tumor metastasis in the abdomen was noted in all patients with metastasis to the appendix. Appendectomy for stage I and II patients was not beneficial and did not affect final staging. As a result, for the proper staging of ovarian carcinoma there is no advantage to the addition of routine appendectomy to primary cytoreductive surgery in early stage (stage I and II) malignant epithelial ovarian tumors. Appendectomy would contribute to the cytoreduction of advanced stage disease if it is macroscopically involved.

    Objective: To discuss the technique, efficacy and clinical significance of cryoablation combined with transcatheter arterial chemoembolization(TACE) for the treatment of advanced hepatic carcinoma. Methods: One hundred and ninety-two patients, who accorded with the selected criterion, were divided into TACE group (n=100) and combination group (cryotherapy combined with TACE, n=92). Pre-and post-treatment AFP level, recurrence rate and life span between two groups were compared. Results: The complete necrosis rate of the tumor and the recurrence rate in TACE group were 29% and 42%, which were 88.04% and 24% in combination group, respectively. The serum AFP level was significantly decreased after treatment in both groups (P<0.05), and the reduction in AFP level was significantly greater in combination group than that in TACE group (P<0.05). During a follow-up of 30 months the survival rate at each evaluation period of combination group was higher than that of TACE group without exception. Conclusion: As an effective and safe technique, cryoablation combined with chemoembolization is far superior to simple TACE in treating advanced hepatic carcinoma. (authors)

    Urachal carcinoma is a rare neoplasm, which accounts for only 0.5–2% of bladder malignancies, and arises from a remnant of the fetal genitourinary tract. A 46-year-old woman presented with a history of pelvic pain and frequent daytime urination. Ultrasound (US), computed tomography (CT), and magnetic resonance (MR) demonstrated a supravesical heterogeneous mass with calcifications. The patient underwent a partial cystectomy with en-bloc resection of the mass and histopathological examination revealed the diagnosis of urachal adenocarcinoma. Urachal carcinomas are usually associated with poor prognosis and early diagnosis is fundamental. CT and MR are useful to correctly diagnose and preoperatively staging

    Hepatocellular carcinoma (HCC) is a leading cause of cancer-related death worldwide. The early diagnosis of HCC is greatly helpful to achieve long-term disease-free survival. However, HCC is usually difficult to be diagnosed at an early stage. The aim of this study was to create the prediction model to diagnose HCC based on gene expression programming (GEP). GEP is an evolutionary algorithm and a domain-independent problem-solving technique. Clinical data show that six serum biomarkers, including gamma-glutamyl transferase, C-reaction protein, carcinoembryonic antigen, alpha-fetoprotein, carbohydrate antigen 153, and carbohydrate antigen 199, are related to HCC characteristics. In this study, the prediction of HCC was made based on these six biomarkers (195 HCC patients and 215 non-HCC controls) by setting up optimal joint models with GEP. The GEP model discriminated 353 out of 410 subjects, representing a determination coefficient of 86.28% (283/328) and 85.37% (70/82) for training and test sets, respectively. Compared to the results from the support vector machine, the artificial neural network, and the multilayer perceptron, GEP showed a better outcome. The results suggested that GEP modeling was a promising and excellent tool in diagnosis of hepatocellular carcinoma, and it could be widely used in HCC auxiliary diagnosis.

    Full Text Available Gorlin-Goltz syndrome or basal cell nevus syndrome is an autosomal dominant syndrome characterized by skeletal anomalies, numerous cysts observed in the jaw, and multiple basal cell carcinoma of the skin, which may be accompanied by falx cerebri calcification. Basal cell carcinoma is the most commonly skin tumor with slow clinical course and low metastatic potential. Its concomitance with Gorlin syndrome, resulting from a mutation in a tumor suppressor gene, may substantially change morbidity and mortality. A 66-year-old male patient with a history of recurrent basal cell carcinoma was presented with exophthalmus in the left eye and the lesions localized in the left lateral orbita and left zygomatic area. His physical examination revealed hearing loss, gapped teeth, highly arched palate, and frontal prominence. Left orbital mass, cystic masses at frontal and ethmoidal sinuses, and multiple pulmonary nodules were detected at CT scans. Basal cell carcinoma was diagnosed from biopsy of ethmoid sinus. Based on the clinical and typical radiological characteristics (falx cerebri calcification, bifid costa, and odontogenic cysts, the patient was diagnosed with metastatic skin basal cell carcinoma accompanied by Gorlin syndrome. Our case is a basal cell carcinoma with aggressive course accompanying a rarely seen syndrome.

    To study the relationship between surgical management and prognosis of adrenocortical carcinoma (ACC) in order to guide the surgical management of ACC. Clinical data of 45 cases of ACC treated in our hospital were retrospectively analyzed. The 45 cases included 3 cases in stage I, 12 cases in stage II, 7 cases in stage III, and 23 cases in stage IV. 17 cases underwent complete excision, 14 cases underwent palliative excision, 8 cases had non-operative treatment and 6 cases gave up treatment. All patients were followed up from 2 to 141 months. The average survival time of 31 patients with surgery was 32.46 months, and the average survival time of 14 patients without surgery was 4.75 months. There were statistically significant differences between the two groups (p 0.05). Surgery is considered to be the only method to cure ACC. For ACC in stage I and II, tumor resection is the most effective treatment, and second surgical operation is recommended for local recurrence. For ACC in stage III, extensive surgical operation is recommended, and for ACC in stage IV, surgical operation has no effect on the prognosis. Copyright © 2012 S. Karger AG, Basel.

    To compare the efficacy of carbon dioxide (CO/sub 2/) laser with cutting diathermy as a cutting device in surgical excision of early carcinoma tongue. Study Design: Experimental study. Place and Duration of Study: Combined Military Hospital (CMH), Rawalpindi and CMH, Lahore, from July 2008 to July 2011. Methodology: Twenty two biopsy proven cases of T1 and early T2 squamous cell carcinoma of tongue were divided in two equal groups of 11 each labeled as A and B. Tumor was excised by CO/sub 2/ laser in group A while cutting diathermy was done in group B. For both groups tumor excision time, per-operative blood loss, postoperative oral swelling and pain was recorded. Excision time of tumor was assessed in minutes and amount of blood loss in milliliters till complete hemostasis after removal of primary tumor. Postoperatively patients were assessed on 12 hourly basis for 48 hours for pain. Pain was analyzed on visual analogue score 1 - 10. Oral swelling was assessed once after 24 hours and labeled as mild, moderate and severe. Independent sample t-test was applied for analysis of excision time, postoperative pain and per-operative blood loss for both groups. Postoperative swelling was analyzed using Fisher exact test. P-value of < 0.05 was considered significant. Results: The mean age at diagnosis in group A was 49.36 ± 5.27 years, while in group B patients had mean age of 50.73 ± 8.13 years. In group A, 4/11 (36.3%) patients were having tumor stage T1 while 7/11 (63.6%) had T2 stage tumor. In group B, 5/11 (45.4%) were having T1 and 6/11 (54.5%) were having stage T2 tumor. Excision time was significantly shorter for group B (p=0.003), but group A had less postoperative pain (p=0.001), less per-operative blood loss (p=0.001) and less postoperative oral swelling (p=0.021). Conclusion: Early carcinoma tongue is better removed by laser than electrocautery in terms of postoperative morbidity, per-operative blood loss, postoperative pain and oral swelling. (author)

    AIM: To retrospectively review the surgical histological findings in all cases where lobular carcinomain situ (LCIS) was identified on percutaneous core biopsy (CB) performed as part of the Cambridge and Huntingdon breast screening programme. MATERIALS AND METHODS: We retrospectively reviewed all the core biopsies performed in our department for screen detected abnormalities over a 5-year period between 1 April 1994 and 31 March 1999. All patients where LCIS was identified on CB were reviewed. As the significance of LCIS on CB was unclear all went on to surgical excision. We reviewed the clinical and imaging findings, biopsy technique and subsequent surgical histology of each patient. RESULTS: During the study period 60 769 women were invited for screening, of whom 47 975 attended (attendance rate 79%). Of these, 2330 (4.9%) were recalled for assessment and 749 (1.6%) underwent CB. A malignant diagnosis was obtained in 311 (42%), 211 invasive and 100 in situ lesions. LCIS was identified on CB in 13 (2%). LCIS was the only lesion identified in seven cases. All seven cases subsequently underwent surgical excision. Surgical histology revealed a single case of LCIS and invasive lobular carcinoma. There were two cases of LCIS and DCIS one with a probable focus of invasive ductal carcinoma. In one case LCIS was identified in association with a radial scar. In three of the seven cases LCIS was the only abnormality on both CB and surgical biopsy. CONCLUSION: Our series shows that isolated LCIS on CB following mammographic screening is an infrequent finding, and it may be associated with either an invasive cancer or DCIS. It is therefore advisable that when LCIS is identified on CB, surgical excision of the mammographic abnormality should be performed. Decisions on management should be undertaken in a multidisciplinary setting taking into account clinical and imaging findings. O'Driscoll, D. et al. (2001)

    Full Text Available Background: Development of skin neoplasms is one of the most important chronic complications of radiation therapy. Basal cell carcinoma (BCC is the most frequent carcinoma occurring at the region of the body to which radiotherapy was delivered. Aim: The aim of this study was to evaluate clinical and histological aspects of basal cell carcinoma in patients with a history of radiotherapy. Materials and Methods: Medical records and microscopic slides of 80 patients with basal cell carcinoma who had received radiotherapy (1996-2006 were reviewed in pathology department of Imam Reza hospital of Mashhad, Iran. Collected data were analyzed statistically using descriptive test. Results: 60 men and 20 women were included, majority of them in their sixties. Plaque was the most common clinical pattern of basal cell carcinoma. Fifty one percent of the patients had pigmented and 42.5% had multiple lesions. Scalp was the most common site of involvement. Histologically, macronodular and pigmented carcinoma were the most predominant forms of basal cell carcinoma. Discussion: Majority of patients had scalp involvement and multiple lesions. Nodular and pigmented forms were the most common histological findings. We suggest the need for close supervision in patients with a history of radio therapy in the past.

    Most prognostic studies in differentiated carcinoma have included a high number of papillary carcinomas and few follicular carcinomas, and not all of their conclusions therefore apply to the latter. To analyze the prognostic factors of follicular thyroid carcinoma. Patients with histological diagnosis of follicular carcinoma who had undergone potentially curative surgery, had no disseminated disease at diagnosis, and had been followed up for at least 5 years. Tumor recurrence was defined as: 1) tumor lesions with cytological analysis suggesting malignancy and/or 2) patients with total thyroidectomy with thyroglobulin levels >2 ng/mL. Clinical, therapeutic, and histological parameters were analyzed to assess prognostic factors. Recurrence was found in 25 (38%) of the 66 study patients during a follow-up period of 99 ± 38 months. Most patients with recurrence (n=20) had increased Tg levels without anatomical location, and were initially treated with radioactive I131. In the remaining 5 cases, surgical excision of the lesion was performed, and three patients required surgery during the follow-up period. Two patients died due to the disease (3%), and two other patients (3%) currently have distant metastases. Mean disease-free interval was 154 ± 14 months, and rates of disease-free patients at 5, 10, 15, and 20 years were 71, 58, 58, and 58% respectively. Clinical factors influencing recurrence included 1) age (p=0.0035); 2) sex (p=0.0114); and 3) cervical pain (p=0.0026). Histological/surgical factors associated with recurrence included 1) infiltration into neighboring structures (p=0.0000); 2) type of carcinoma (p=0.0000); 3) size (p=0.0162); 4) vascular invasion (p=0.0085); and 5) adenopathies (p=0.046). In the multivariate study, cervical pain (p=0.018) and extrathyroid invasion (p=0.045) continued to be significant factors. In follicular carcinoma, rates of disease-free patients are 71% at 5 years and 58% at 10 years, and the main predictive factors are presence

  17. Radiotherapy - an effective treatment for vaginal verrucous carcinoma

    Vaginal carcinoma makes up 1%-2% of all gynaecological tumours. Verrucous carcinoma of the vagina is even more rare -only 16 cases are reported in the scientific literature. A case of a complete regression after 60 Gy fractionated radiotherapy by a tumour 12 cm 3 in size is reported. Most authors are of the opinion that radiotherapy causes anaplastic transformation of verrucous carcinoma. The minority view, that anaplastic transformation does not occur, is correct and is supported by our clinical and radiological data. The conflicting literature on vaginal verrucous carcinoma (VVC) is reviewed with reference to verrucous carcinoma at other sites. (Author)

    Objective: To assess the role of three-dimensional (3D) CT imaging including CT virtual gastroscopy (CTVG), surface-shaded display (SSD), and Raysum Display in the evaluation of gastric carcinoma compared with upper gastrointestinal series (UGI). Methods: In 43 histologically proved gastric carcinoma patients (37 advanced gastric carcinomas and 6 early gastric carcinomas), the results of CTVG and 3D CT imaging were compared to that of UGI. Two observers blindly evaluated images with all four techniques in terms of image quality, artifacts, diagnostic confidence, and Borrmann classification. Sensitivities of lesion detection and classification based on Borrmann classification of CTVG and 3D CT were determined by comparing them to surgical and histological findings. Results: The lesion detection sensitivity of CTVG, SSD, Raysum, and UGI by two observers were 98%, 67%, 60% and 84%, and 98%, 70%, 70% and 88%, respectively. The Borrmann's classification sensitivity by two observers were 76%, 49%, 38% and 49%, and 78%, 51%, 35% and 43%, respectively. Overall image quality of CTVG, SSD, and Raysum was considered similar to that of UGI by both observers (P>0.05). There was no statistical significant difference for advanced lesion (with diagnostic confidence of 3 or above) in detection sensitivity between CTVG and UGI (χ 2 = 0.50 and 0.25, P>0.05), but the lesion detection sensitivity of SSD and Raysum display were lower than that of UGI (χ 2 4.17, 7.11 and 5.14, 4.17, P 2 = 4.90 and 4.92, P 2 = 2.25, P > 0.05). Excess fluid remained in the stomach and patient respiratory movement during breath holds were the reasons causing severe artifacts (6.1%) that influenced the diagnostic evaluation. Conclusion: The performance of CTVG was equivalent to UGI in the Borrmann's classification. CTVG has potential in the detection of early gastric carcinoma. The value of SSD and Raysum display was limited in the evaluation of gastric carcinoma when used alone clinically

    Basal cell carcinoma (BCC) is the most common skin cancer among Orientals. Data on this malignancy is lacking in Malaysia, prompting a retrospective study to determine the clinical characteristics in the skin clinic, Sarawak General Hospital between 2000 and 2008. Demographic data and clinical features of 64 histopathologically proven BCC from 43 patients were retrieved. Statistical analysis was performed comparing the clinical characteristics based on the region of involvement and gender. The mean age of presentation was 60.9 years. Male to female ratio was 1.05. Majority of the patients were Chinese (44.2%) followed by Malays (32.6%), Bidayuhs (14.0%) and Ibans (6.9%). Nodular BCC accounted for 95.3% of cases while 4.7% were superficial BCC. All the nodular BCC were pigmented. Ulceration was noted in 18%. There were 82.8% of BCC on the head and neck region and 17.2% on the trunk and limb region. BCC on the latter region were larger (mean 35.0 cf. 14.4 mm, p Sarawak were similar to other Asian studies. Additionally, BCC on the trunk and limbs and in men were larger, ulcerative and long standing warranting better efforts for earlier detection.

    In intracavitary radiation therapy of carcinoma of the uterine cervix, deviated position of microsources in the uterine and vaginal cavities from standard position was classified as follows: (1) Slipped position of a whole system of microsources. (2) Slipped position of the uterine tandem. (3) Slipped position of the colpostat. (4) Anteversion-flexion position of the uterine tandem. (a) Anterior displacement of the vaginal colpostat. (b) Posterior displacement of the vaginal colpostat. (5) Retroversion-flexion position of the uterine tandem. (a) Posterior displacement of the vaginal colpostat. (b) Retroposed position of the uterine tandem. (6) Side inclination of the uterine tandem. In every position, dose distribution around microsources was calculated by computers and isodosecurves in the vicinity of the cervix were constructed in three dimensions. Advantage and disadvantage of shape of these isodosecurves were discussed clinically with special reference to dosage of the lesions, rectum and bladder which was delivered from microsources. Besides these studies we clarified the reason why adequate cancerocidal dosage of carcinoma of the uterine cervix in the aged was much less than in the younger on the basis of anatomical and tumor size difference between two groups. The similar difference could be found between Japanese and Westerns in radiation therapy of carcinoma of the uterine cervix. (author)

    Treatment of head and neck cancer is complex, and a multidisciplinary clinic may improve the coordination of care. The value of a head and neck multidisciplinary clinic has not yet been established in oropharyngeal squamous cell carcinoma (SCC). A retrospective review was conducted of Veterans Affairs patients with oropharyngeal SCC undergoing concurrent chemoradiation before and after implementation of the head and neck multidisciplinary clinic. Fifty-two patients before and 54 patients after multidisciplinary clinic were included in this study. Age, tobacco use, and p16+ status were similar between groups. With multidisciplinary clinic, time to treatment decreased, and utilization of supportive services, including speech pathology, dentistry, and nutrition increased. The 5-year disease-specific survival rate increased from 63% to 81% (p = .043) after implementation of the multidisciplinary clinic. Multivariate analysis showed that disease stage (p = .016), p16 status (p = .006), and multidisciplinary clinic participation (p = .042) were predictors of disease-specific survival. Implementation of a multidisciplinary clinic improved care coordination and disease-specific survival in patients with oropharyngeal SCC. © 2017 Wiley Periodicals, Inc.

    A study on the diagnosis of carcinoma of the stomach was carried out in 105 selected Korean cases of histologically proved carcinoma of the stomach, aimed to the position and value of roentgenography and gastroscopy. The results were summarized as follows: 1) In the diagnosis of 105 cases of Korean gastric carcinomas, a correct diagnosis was made by roentgenography in 79.1 percent and by gastroscopy in 86.7 percent of all cases. Roentgenography plus gastroscopy permitted a correct diagnosis in 92.3 percent of all cases. There is no significant difference statistically on the diagnostic accuracy between roentgenography and gastroscopy (by t-test, t=0.8572). 2) In the diagnosis of carcinoma of the stomach, with roentgenography the greatest diagnostic error occurred in primary ulcerative lesions and with gastroscopy in inadequate examinations which were resulted from mechanical failures. It occurred also in mixed type of infiltration and ulceration for the gross pathology and in lesions of gastric body and pyloric antrum as the site of the lesion. 3) In this series of 105 cases of Korean gastric carcinomas, two cases of early gastric carcinoma (type IIc +III) were correctly diagnosed by roentgenography and gastroscopy. 4) In this series, the most frequent type of gross pathology appeared to be Bormann tpe III, type of ulceration with spreading infiltration, which was 72.4 percent of all 105 cases and the site of the lesion revealed the highest frequently in the pylorus in 53.3 percent, but both of these had little significance in the determination of diagnostic accuracy of roentgenography and/or gastroscopy in gastric carcinomas. 5) The onset of symptoms, clinical manifestations, and physical findings were reviewed in all 105 cases of this series. The predominant symptoms were epigastric pain (75.2 percent), indigestion (73.3 percent) and weight lose (57.0 percent) in the order and the most frequent physical findings was epigastric tenderness (68.6 percent).

    Objective: To study the clinical applicability of single/combined determination of six tumor markers (CEA, CA125, CA50, CA19-9, CA153, CYFRA21-1) for diagnosis of pulmonary carcinoma. Methods: Serum contents of these six tumor markers were determined with RIA in 130 patients with pulmonary carcinoma, 40 patients with various benign pulmonary disorders, and 45 controls. Results: (1) Only two false positive cases were found in the 40 patients with benign pulmonary disorders (CA125, n=1, CA153 n=1). (2) Positive rate of single marker in patients with pulmonary cancer: CYFRA21-1 (79.23%)>CA153 (61.53%) > CA125(58.46%)> CA19-9(57.69%) > CEA(46.92%) > CA50(43.84%). (3) Combined determination of CYFRA21-1 with any one of the other 5 markers would increase the positive rate to 86.15%-89.23%. (4) Mean value of any marker in the malignant cases were over 4 folds of that in the benign cases-high diagnostic credibility. (5) Histology of the malignancy (squamous cell carcinoma or adenocarcinoma) made no difference on the positive rate of the markers with the exception of a slight higher positive rate of CA19-9 in adenocarcinomas. Conclusion: The authors believe that combined determination of CYFRA21-1 with CA153 would be the first choice for diagnosis of pulmonary carcinoma, followed by CYFRA21-1 + CA125 or CA19-9. (authors)

    Full Text Available Metastasis of prostate carcinoma to the testis is seldom reported. The tumour may spread from the prostatic urethra by retrograde venous extension, arterial embolism or through direct invasion into the lymphatics and lumen of the vas deferens. Clinical manifestations of secondary testicular tumours from the prostate are most often unsuspected clinically and are instead detected incidentally during orchidectomy. Less frequently, a palpable mass is detected, which may be confused with a primary testicular neoplasm. We report a case of a 66-year-old patient with adenocarcinoma of the prostate, and a left testicular tumour that was diagnosed as metastases from prostate carcinoma after radical orchidectomy.

    Recently, magnetic resonance imaging (MRI) and transrectal or transvaginal ultrasound (TRUS, TVUS) had an important place in imaging techniques of cervical carcinomas and raise the question of modifying the imaging strategies. For the diagnosis of primitive tumor, those techniques cannot take the place of clinical examination and gross examination. In the assessment of parametrial involvement, TRUS which has better accuracy than clinical examination, and MRI which is considered as the most accurate technique, have an important role to play. In the follow-up and the detection of recurrences, MRI is actually considered as the best imaging technique. The authors, according to recent data in literature and their own experience, present basic concepts of imaging strategies for staging and follow-up of cervical carcinomas [fr

    A case of clear cell carcinoma of the endometrium following squamous cell carcinoma of the cervix is reported. The patient had had a previous cervical biopsy which revealed squamous cell carcinoma (large cell non-keratinizing type), classified clinically as a stage IIb lesion. She was treated with external pelvic irradiation delivering an estimated tumor dose of approximately 7,000 rads and intracavital radium application delivering 4,995 mg.hr.radiation when she was 51 years old. She complained of post-menopausal bleeding at age 66 and was diagnosed by endometrial cytology as having clear cell carcinoma of the endometrium. Total abdominal hysterectomy, bilateral salpingo-oophorectomy and omentectomy were performed. The clinical stage of the endometrial cancer was Ib. She is alive after 2 years with no evidence of disease. Endometrial cytology revealed several adenocarcinoma cells in small clusters. The shape of the nuclei was somewhat irregular, the chromatin pattern was fine granular, and single or multiple nucleoli were seen. The diameter of these nuclei ranged from 10 to 30 μm. The cytoplasm was pale green or vacuolated. The volume of the cytoplasm varied from scanty to abundant. These findings suggested clear cell carcinoma. Histopathologically, an irregular shaped polypoid tumor, 3 x 1.5 cm in size, was located on the lower anterior wall of the uterine corpus. The tumor was a clear cell carcinoma showing a solid and papillary pattern. A hobnail pattern was not observed. The cytoplasm was clear and abundant, and PAS-positive granules digestible by diastase were seen. These 2 cancers had different pathological features and their immunohistochemical reactivities for CEA and keratin were also different. The patient was regarded as having a rare heterochronous double cancer consisting of squamous cell carcinoma of the cervix and clear cell carcinoma of the endometrium. (author)

    Full Text Available Hepatocellular carcinoma (HCC is one of the common lethal types of tumor all over the world. The lethality of HCC accounts for many reasons. One of them, the lack of reliable diagnostic markers at the early stage, in this context, serum miRNAs became promising diagnostic biomarkers. Herein, we aimed to identify the predictive value of two miRNAs (miR-122 and miR-224 in plasma of patients with HCC preceded by chronic HCV infection. Taqman miRNA assays specific for hsa-miR-122 and hsa-miR-224 were used to assess the expression levels of the chosen miRNAs in plasma samples collected from three groups; 40 patients with HCC related to HCV, 40 with CHC patients and 20 healthy volunteers. This study revealed that the mean plasma values of miRNA-122 were significantly lower among HCC group when compared to CHC and control groups (P 1.2 (RQ and (AUC = 0.93, P < 0.001, while the accuracy of AFP to diagnose HCC was (AUC: 0.619; P = 0.06. In conclusion, the expression plasma of miR-122 and miR-224 could be used as noninvasive biomarkers for the early prediction of developing HCC at the early stage.

    Merkel cell carcinoma (MCC) is a highly malignant skin cancer characterized by early metastases and poor survival. Although MCC is a rare malignancy, its incidence is rapidly increasing in the U.S. and Europe. The discovery of the Merkel cell polyomavirus (MCPyV) has enormously impacted our understanding of its etiopathogenesis and biology. MCCs are characterized by trilinear differentiation, comprising the expression of neuroendocrine, epithelial and B-lymphoid lineage markers. To date, it is generally accepted that the initial assumption of MCC originating from Merkel cells (MCs) is unlikely. This is owed to their post-mitotic character, absence of MCPyV in MCs and discrepant protein expression pattern in comparison to MCC. Evidence from mouse models suggests that epidermal/dermal stem cells might be of cellular origin in MCC. The recently formulated hypothesis of MCC originating from early B-cells is based on morphology, the consistent expression of early B-cell lineage markers and the finding of clonal immunoglobulin chain rearrangement in MCC cells. In this review we elaborate on the cellular ancestry of MCC, the identification of which could pave the way for novel and more effective therapeutic regimens. Copyright © 2017 The Authors.

    Purpose: We compared clinical outcomes of women diagnosed with either invasive lobular carcinoma (ILC) or invasive ductal carcinoma (IDC) treated with accelerated partial breast irradiation (APBI). Methods and Materials: A total of 16 patients with ILC received APBI as part of their breast-conservation therapy (BCT) and were compared with 410 patients with IDC that received APBI as part of their BCT. Clinical, pathologic, and treatment related variables were analyzed including age, tumor size, hormone receptor status, surgical margins, lymph node status, adjuvant hormonal therapy, adjuvant chemotherapy, and APBI modality. Clinical outcomes including local recurrence (LR), regional recurrence (RR), disease-free survival (DFS), cause-specific survival (CSS), and overall survival (OS) were analyzed. Results: Median follow-up was 3.8 years for the ILC patients and 6.0 years for the IDC patients. ILC patients were more likely to have positive margins (20.0% vs. 3.9%, p = 0.006), larger tumors (14.1 mm vs. 10.9 mm, p = 0.03) and less likely to be node positive (0% vs. 9.5%, p < 0.001) when compared with patients diagnosed with IDC. The 5-year rate of LR was 0% for the ILC cohort and 2.5% for the IDC cohort (p = 0.59). No differences were seen in the rates of RR (0% vs. 0.7%, p = 0.80), distant metastases (0% vs. 3.5%, p = 0.54), DFS (100% vs. 94%, p = 0.43), CSS (100% vs. 97%, p = 0.59), or OS (92% vs. 89%, p = 0.88) between the ILC and IDC patients, respectively. Additionally, when node-positive patients were excluded from the IDC cohort, no differences in the rates of LR (0% vs. 2.2%, p = 0.62), RR (0% vs. 0%), DFS (100% vs. 95%, p = 0.46), CSS (100% vs. 98%, p = 0.63), or OS (92% vs. 89%, p = 0.91) were noted between the ILC and IDC patients. Conclusion: Women with ILC had excellent clinical outcomes after APBI. No difference in local control was seen between patients with invasive lobular versus invasive ductal histology.

    Esophageal cancer is the sixth leading cause of cancer death worldwide; current early detection screening tests are inadequate. Esophageal balloon cytology successfully retrieves exfoliated and scraped superficial esophageal epithelial cells, but cytologic reading of these cells has poor sensitivity and specificity for detecting esophageal squamous dysplasia (ESD), the precursor lesion of esophageal squamous cell carcinoma (ESCC). Measuring telomere length, a marker for chromosomal instability, may improve the utility of balloon cytology for detecting ESD and early ESCC. We examined balloon cytology specimens from 89 asymptomatic cases of ESD (37 low-grade and 52 high-grade) and 92 age- and sex-matched normal controls from an esophageal cancer early detection screening study. All subjects also underwent endoscopy and biopsy, and ESD was diagnosed histopathologically. DNA was extracted from the balloon cytology cells, and telomere length was measured by quantitative PCR. A receiver operating characteristic (ROC) curve was plotted for telomere length as a diagnostic marker for high-grade dysplasia. Telomere lengths were comparable among the low- and high-grade dysplasia cases and controls, with means of 0.96, 0.96, and 0.92, respectively. The area under the ROC curve was 0.55 for telomere length as a diagnostic marker for high-grade dysplasia. Further adjustment for subject characteristics, including sex, age, smoking, drinking, hypertension, and body mass index did not improve the use of telomere length as a marker for ESD. Telomere length of esophageal balloon cytology cells was not associated with ESCC precursor lesions. Therefore, telomere length shows little promise as an early detection marker for ESCC in esophageal balloon samples

    To correlate early changes in the parameters of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) within 1 week of systemic therapy with overall survival (OS) in patients with advanced hepatocellular carcinoma (HCC). Eighty-nine patients with advanced HCC underwent DCE-MRI before and within 1 week following systemic therapy. The relative changes of six DCE-MRI parameters (Peak, Slope, AUC, Ktrans, Kep and Ve) of the tumours were correlated with OS using the Kaplan-Meier model and the double-sided log-rank test. All patients died and the median survival was 174 days. Among the six DCE-MRI parameters, reductions in Peak, AUC, and Ktrans, were significantly correlated with one another. In addition, patients with a high Peak reduction following treatment had longer OS (P = 0.023) compared with those with a low Peak reduction. In multivariate analysis, a high Peak reduction was an independent favourable prognostic factor in all patients [hazard ratio (HR), 0.622; P = 0.038] after controlling for age, sex, treatment methods, tumour size and stage, and Eastern Cooperative Oncology Group performance status. Early perfusion changes within 1 week following systemic therapy measured by DCE-MRI may aid in the prediction of the clinical outcome in patients with advanced HCC. (orig.)

    The aim of this study was to determine the proportion of human papilloma virus (HPV)-positive cases in tonsillar carcinomas and investigate its development over the last decade. Further aim was to show the oncologic results in accord to HPV status and various treatment modalities. A retrospective study was conducted between 2000 and 2012 and included 275 patients treated for tonsillar carcinoma. P16 immunohistochemistry was used as a surrogate marker for HPV-associated carcinogenesis. A total of 101 (36.7%) patients proved to be p16 positive and 174 p16 negative. 80.2% of the p16-positive cases presented with T1-2 tumor. Of the early-stage patients, 79% of the p16-positive and 52.3% of the p16-negative presented with lymph node metastases. The percentage of p16-positive patients increased from 23.2% in the period 2005–2007 to 58.6% in the period 2010–2012 in the whole population and from 30.9% to 76.9% in T1-2 carcinomas. Early T-category p16-positive carcinomas had significantly better disease-specific survival (92.4% vs. 75.5%, P = 0.007) and overall survival (OS, 79.6% vs. 54.3%, P < 0.001) compared to p16-negative tumors. This study showed an increase in the percentage of p16-positive patients in tonsillar carcinoma from 23.2% in the years between 2005 and 2007 to 58.6% between 2010 and 2012. The majority (80.2%) of p16-positive patients presented with early T-category tumor but most of these (79.0%) had also lymph node metastases. Nevertheless, p16-positive patients had excellent oncologic results after surgery and adjuvant radiotherapy and could be considered for de-escalation of treatment

    Incidence of thyroid cancer is increasing in Spain and worldwide. Overall thyroid cancer survival is very high, and stratification systems to reliably identify patients with worse prognosis have been developed. However, marked differences exist between the different specialists in clinical management of low-risk patients with thyroid carcinoma. Almost half of all papillary thyroid carcinomas are microcarcinomas, and 90% are tumors < 2 cm that have a particularly good prognosis. However, they are usually treated more aggressively than needed, despite the lack of adequate scientific support. Surgery remains the gold standard treatment for these tumors. However, lobectomy may be adequate in most patients, without the need for total thyroidectomy. Similarly, prophylactic lymph node dissection of the central compartment is not required in most cases. This more conservative approach prevents postoperative complications such as hypoparathyroidism or recurrent laryngeal nerve injury. Postoperative radioiodine remnant ablation and strict suppression of serum thyrotropin, although effective for the more aggressive forms of thyroid cancer, have not been shown to be beneficial for the treatment of low risk patients, and may impair their quality of life. This guideline provides recommendations from the task force on thyroid cancer of the Spanish Society of Endocrinology and Nutrition for adequate management of patients with low-risk thyroid cancer.

    Regardless of advances in diagnosis and treatment during the past 40 years, the overall 5-year survival rates for oral and oropharyngeal squamous cancers have only slightly improved and remain around 50%. Thus, the early diagnosis and treatment of carcinoma by health care providers are essential in achieving a good prognosis. We report a case of invasive squamous cell carcinoma that presented as a benign endodontic-periodontic lesion with a 7-mm periodontal pocket on tooth #15 in a 40-year-old, non-smoking woman. The subsequent management of the case is also discussed. The study was conducted in accordance with the Helsinki Declaration of 1975, as revised in 2000. Our patient was seen for a comprehensive periodontal examination including a periodontal charting, occlusal analysis, study casts, electronic pulp test for tooth #15, and complete mouth periapical radiographs. As there was a periapical radiolucency, an endodontic consultation was obtained. A periodontal flap surgical procedure was performed on teeth #13 to #15, and as there was bone erosion into the maxillary sinus, a biopsy of the soft tissue was submitted to the local hospital for histological analysis. The biopsied lesion was diagnosed as invasive, moderately differentiated squamous cell carcinoma with focal spindle and clear cell differentiation (grade II to III of IV). Bone invasion was also identified. The treatment of the carcinoma involved a hemimaxillectomy with the removal of the maxillary left posterior teeth. The patient remained free of tumor for 5 years after the initial presentation. Patient education and periodic oral cancer examinations by dental professionals are necessary to reduce diagnostic delay and improve prognosis. This case report emphasizes the important role of dental professionals, especially periodontists and endodontists, of being aware that squamous cell carcinoma may manifest itself clinically and/or radiographically as a common periodontal or endodontic lesion.

Methodology of the study covers optimal drug muscle relaxation of the abdominal wall by injection of 2 sg buskolizin intravenous; maximum distension of the stomach lumen by ingestion of 3 effervescent disintegrated tablets Vit. C with 1-2 sips of water, necessarily using of non-ionic contrast media - 100 ml / 300 mg iodine / 1 ml liquid bolus introduced for 30 seconds. Start scanning - 30 seconds of the start of injection - to visualize the arterial phase, use of slices with a thickness of 3 mm and 2 mm interval; exponential data 120 kV, 160 mAc. Earlier form of gastric cancer have to be presented by 5 CT image: unequal unsmooth, scallop or polycyclic contours of the lining, thinning the complete disappearance of the lining; undulating thickening of the lining; nodal formation like a polyp on a broad basis with a 2-5 mm, double contour of the lining - like a wave. These amendments are localized only in a limited segment of the gastric mucosa. Spiral CT is an effective diagnostic performance in gastric cancer, including the early stage I of cancer development. This is realized only by using the specific methodology of the study as well as good knowledge of the CT images semiology for carcinoma, localized only within a certain perimeter of the stomach lining

    We report a case of endocrine cell carcinoma of the colon with very poor prognosis, onset with bowel obstruction and multiple liver metastases. The patient was a 77-year-old man who underwent left hemicolectomy after a colon stent treatment for bowel obstruction due to cancer of the transverse colon with unresectable multiple liver metastases. Chemotherapy was not initiated because of his poor health. He died of primary cancer 52 days after the surgery. Endocrine cell carcinoma of the large intestine has a poor prognosis due to an early onset of liver and lymph node metastases, as well as peritoneal dissemination. A large-scale clinical study is needed to establish an effective adjuvant chemotherapy.

    To describe the clinical characteristics, treatment patterns and outcomes in advanced small cell bladder cancer (aSCBC) patients and compare to those with urothelial carcinoma (UC). Individuals in the National Cancer Data Base with a diagnosis of either nodal (TxN+M0) or distant metastatic (TxNxM1) disease were identified from 1998 to 2010. We assessed the relationships between stage, treatment modalities and survival in the aSCBC cohort and compared these to UC patients. In the 960 patient aSCBC cohort (62% M1), 50% received palliative therapy alone, 68% in M1 versus 21% in M0 groups (P < 0.0001). Single modality local therapy (15%) and surgical (21%) or radiation-based (14%) multimodal therapy (MMT) were used in the other 50%. Cystectomy-based MMT was utilized in 45% of N+M0 versus 6.4% of NxM1 patients (P < 0.0001). Median overall survival (OS) for aSCBC patients was 8.6 months; 13.0 months in N+M0 versus 5.3 months in NxM1 patients (P < 0.0001). Survival was similar between TxN1M0 and TxN2-3M0 patients (14.8 months vs. 12.1 months, P = 0.15). Urothelial carcinoma patients (n = 27,796, 45% M1) lived longer compared to aSCBC patients in the N+M0 group (17.3 months vs. 13.0 months, P = 0.0007). There were not clinically significant differences in OS between UC and aSCBC patients in the M1 group. Advanced SCBC is a rare disease with a poor survival and palliative therapy is common, especially in M1 patients. In comparison to UC, the outcomes for aSCBC patients are worse in those with lymph node only involvement but similar in those with distant disease

    Full text: To explore the clinical value of PET/CT scanning in search of the primary carcinoma, we selected 4 patients who were subjected to PET/CT examination during Oct. 2002 to Dec. 2002. The primary lesion in all these patients was not detected. One of them had metastasis to liver, one had metastases in both lungs and the other two were having metastases to the bones. 18F-FDG in doses of 5.55MBq / kg body weight was injected to a fasting patient (at least 6 hours). PET/CT whole body examination was done using Discovery LS-PET/CT (GE Medical System, U.S.A.) 40-60 minutes later. In the first patient with metastasis to liver, primary lesion was localized in the transverse colon near the liver. The PET/CT showed multiple high radioactive uptake lesions of different sizes in the liver. No obvious change in position of the colon uptake was seen on the delayed images. After PET/CT, barium examination showed thinned cavity of the colon near the liver with coarse ankylosis of colon wall just like saw tooth. The mucous membrane was destroyed. Of the two patients with metastases in the bone, first - a 31 years old, was diagnosed to have primary lung cancer with multiple metastases to the liver and the bones. PET/CT showed high radioactive uptake in the inferior left lobe near the hilum with irregular shaped uneven distribution. A round high radioactive uptake area of 1.82 x 1.84 x 1.46cm size was also seen in the right lobe of the liver having clear edge and uneven distribution. The destroyed bones (L-10, L-11, L-12, T-1 and ala ossis i lii) showed high radioactive uptake. Second patient, 57-year male was diagnosed to have malignant lymphoma. PET/CT fusion showed high radioactive uptake in the marrow of whole body. Few destroyed parts of bones were also seen on CT images. Several cervical and the thoracic vertebrae as well as the ninth rib showed irregular radioactive accumulation with clear edges and well-distributed tracer raising the possibility of multiple myeloma or

    OBJECTIVES: Considerable controversy exists regarding the merits of elective neck dissection in patients with early stage oral cavity and oropharyngeal squamous cell carcinoma. It is highly desirable to have a method of identifying those patients who would benefit from further treatment of the neck when they are clinically node-negative. The purpose of the present study was to examine the use of sentinel lymph node biopsy in identifying occult neck disease in a cohort of patients with node-negative oral cavity and oropharyngeal squamous cell carcinoma. DESIGN: We evaluated a total of 13 patients with oral cavity and oropharyngeal cancer who were clinically and radiologically node-negative. RESULTS: A sentinel lymph node was found in all 13 patients, revealing metastatic disease in five patients, four of whom had one or more positive sentinel lymph nodes. There was one false negative result, in which the sentinel lymph node was negative for tumour whereas histological examination of the neck dissection specimen showed occult disease. CONCLUSION: In view of these findings, we would recommend the use of sentinel lymph node biopsy in cases of oral cavity and oropharyngeal squamous cell carcinoma, in order to aid the differentiation of those patients whose necks are harbouring occult disease and who require further treatment.

    Full Text Available Verrucous carcinoma (also known as Ackerman tumor is an uncommon exophytic low-grade well-differentiated variant of squamous cell carcinoma. This neoplasm typically involves the oral cavity, larynx, genitalia, skin, and esophagus. It is well known for its locally aggressiveness and for its clinically slow-growing behaviour with minimal metastatic potential. Verrucous carcinoma of oral cavity is so closely aligned with the use of snuff and chewing tobacco that it has been called the “snuff dipper's cancer”. Recent studies have proved the role of HPV. The typical clinical presentation of oral verrucous carcinoma has long been known, as its remarkably innocuous appearance and biological behaviour. In this work, we report a review of the scientific literature and describe a troublesome case of oral verrucous cancer.

    Despite the advances in mammography techniques, it still has a number of limitations. It is estimated that about 10 to 25% of lesions are overlooked in mammograms out of which about two thirds are detected retrospectively by radiologists and oncologists. Causes of missed breast cancer on mammography can be secondary to many factors including those related to the patient (whether inherent or acquired), the nature of the malignant mass itself, poor mammographic techniques, provider factors or interpretive skills of radiologists and oncologists (including perception and interpretation errors). Aim of Work: The aim of this study is to investigate the aforementioned factors hindering early breast cancer detection and in turn lowering mammographic sensitivity and to outline the major guidelines to overcome these factors aiming to an optimum mammographic examination and interpretation by radiologists and oncologists. Subject and Methods: We conducted this multicenter study over a two-year interval. We included 152 histo-pathological proven breast carcinomas that were initially missed on mammography. The cases were subjected to mammography, complementary US, MRI and digital mammography in some cases and all cases were histo-pathologically proven either by FNAB, CNB or open biopsy. Results: Revision of the pathological specimens of these 152 cases revealed 121 infiltrating ductal carcinomas, 2 lobular, 4 mucinous, 14 inflammatory carcinomas, 6 carcinomas in situ (3 of which were intracystic), 2 intraductal papillary carcinomas and 3 cases with Paget's disease of the nipple. In analyzing the causes responsible for misdiagnosis of these carcinomas we classified them into 4 causative factors; patient, tumor, technical or provider factors. Tumor factors were the most commonly encountered, accounting for 44. I %, while provider factors were the least commonly encountered in 14.5%. Carcino- mas were detected using several individual or combined complementary techniques. These

Conclusion RapidArc proved to be a safe, qualitative and advantageous treatment modality for prostate cancer.

  1. Histopathologic risk factors in oral and oropharyngeal squamous cell carcinoma variants: An update with special reference to HPV-related carcinomas

    Science.gov (United States)

    2014-01-01

    Accurate identification of the microscopic risk factors of oral and oropharyngeal (OP) squamous cell carcinomas (SCC) and their morphologic variants is of at most importance, as these generally determine treatment modalities, prognosis and overall patient outcome. The great majority of oral and oropharyngeal squamous cell carcinomas are microscopically described as kerartinizing squamous cell carcinoma (KSCC). They bear certain resemblance to keratinizing stratified squamous epithelium. Tobacco habits and excessive consumption of alcoholic beverages have been considered to be the main etiologic agents in these carcinomas. The tumors occurred in older patients more commonly affected the oral tongue and floor of the mouth with well established morphologic risk factors including tumor grade, pattern of invasion and perineural involvement. Within the last 30 years however, the advent and expanding prevalence of high risk human papillomavirus (HPV) as an important etiologic agent for head and neck squamous cell carcinoma, particularly in the OP, has resulted in a significant change in the established morphologic criteria for risk assessment. The majority of HPV relate carcinomas of the OP are nonkeratinizing squamous cell carcinoma (NKSCC). These tumors are found to be more responsive to treatment with a favorable patient outcome and good prognosis. Consequently, alterations in treatment protocols aimed at de-escalation are currently being evaluated. More recently, other morphologic variants that are HPV positive are reported with increasing frequency in the OP and other head and neck sites. As a result, several clinical and pathologic questions have emerged. Importantly, whether the virus is biologically active in these tumors and involved in their pathogenesis, and second, what are the clinical implications with regard to patient management and outcome in the HPV-related variants. Examples of HPV-related squamous cell carcinoma variants that will be addressed here are

    This single-center retrospective study of prospectively collected data was aimed at comparing the clinical outcomes of positron emission tomography/computed tomography (PET/CT) for patients with oral cavity squamous cell carcinoma (OSCC) with symptomatic recurrences identified by PET/CT imaging following adjuvant therapy (Group A) versus those of cases with asymptomatic recurrences diagnosed through periodic post-adjuvant therapy PET/CT surveillance (Group B). We also sought to establish the priority of salvage therapy in the two study groups. We identified 111 patients with advanced resected OSCC who developed recurrences following adjuvant therapy (51 in Group A and 60 in Group B). Histopathology served as the gold standard for recurrent lesions. The impact of post-adjuvant therapy PET/CT surveillance was examined with Kaplan-Meier curves and Cox proportional hazards regression models. The 2-year DSS and OS rates were marginally or significantly higher in Group B than in Group A (P = 0.073 and P = 0.025, respectively). Time-dependent ROC curve analysis demonstrated that the optimal cutoff values for time to positive PET/CT findings in relation to OS were 12 months for Group A and 9 months for Group B, respectively. Independent risk factors identified in multivariate analyses were used to devise two prognostic scoring systems for 2-year DSS and OS in each study group (all P < 0.001). Scheduled periodic PET/CT surveillance is a valuable tool for early detection of recurrent lesion(s) in asymptomatic OSCC patients who bear risk factors for disease recurrence. The presence of clinical symptoms and a short time to positive PET/CT findings were adverse prognostic factors for clinical outcome in patients with advanced OSCC. The priority of salvage therapy is discussed in each patient subgroup according to the devised prognostic scoring systems. (orig.)

    To assess patient characteristics and clinician-rated outcomes for children diagnosed with early-onset bipolar disorder in comparison to a depressive disorders cohort from a single clinic site. To assess predictors of bipolar treatment response. Medical records from 714 consecutive pediatric patients evaluated and treated at an academic tertiary child and adolescent psychiatry clinic between 2006 and 2012 were reviewed. Charts of bipolar children (n = 49) and children with depressive disorders (n = 58) meeting study inclusion/exclusion criteria were compared on variables assessing clinical characteristics, treatments, and outcomes. Outcomes were assessed by using pre- and post-Clinical Global Impressions (CGI)-Severity and Children's Global Assessment Scale (CGAS) scores, and a CGI-Improvement score ≤2 at final visit determined responder status. Bipolar outcome predictors were assessed by using multiple linear regression. Clinic prevalence rates were 6.9% for early-onset bipolar disorder and 1.5% for very early-onset bipolar disorder. High rates of comorbid diagnoses, symptom severity, parental stress, and child high-risk behaviors were found in both groups. The bipolar cohort had higher rates of aggression and higher lifetime systems of care utilization. The final CGI and CGAS outcomes for unipolar depression patients differed statistically significantly from those for the bipolar cohort, reflecting better clinical status and more improvement at outcome for the depression patients. Both parent-reported Child Behavior Checklist total T-score at clinic admission and the number of lifetime systems-of-care for the child were significantly and inversely associated with improvement for the bipolar cohort. Early-onset bipolar disorder is a complex and heterogeneous psychiatric disorder. Evidence-based treatment should emphasize psychopharmacology with adjunctive family and individual psychotherapy. Strategies to improve engagement in treatment may be especially

    The serum levels of SCC antigen (squamous cell carcinoma related antigen) were measured in 111 patients with primary lung cancer to assess its clinical usefulness for diagnosis of squamous cell carcinoma and for monitoring recurrence and effectiveness of therapies. Serum SCC antigen level in patients with squamous cell carcinoma of the lung was 5.9 ± 10.4 ng/ml, which was high (p < 0.05) compared with those in normal controls (1.6 ± 0.5 ng/ml), patients with other types of lung cancer (2.4 ± 2.9 ng/ml) or benign disease (1.8 ± 1.1 ng/ml). Studies at various clinical stages of squamous cell carcinoma of the lung showed, however, that the SCC antigen levels were high only in the advanced stages (III and IV), whereas not so high in the earlier stages. These results confirmed that SCC antigen is a relatively specific marker to squamous cell carcinoma in the lung, as reported in the uterine cervix and the esophagus. The SCC antigen levels decreased after operation and more markedly after radiotherapy in dose-dependent manner, corresponding to the reduction of the tumor size. On the other hand, the SCC antigen levels were extremely high in the recurrence. It was concluded that SCC antigen is a useful marker for monitoring recurrence or effectiveness of the therapies of SCC of the lung, although not so for its early diagnosis. (author)

    To evaluate the outcome of early stage non-small cell lung cancer patients who were treated with radiation therapy along and define the optimal radiotherapeutic regimen for these patients. A retrospective review was performed on patients with sage I or II non-small cell carcinoma of the lung that were treated at our institution between June, 1987 and May, 2000. A total of 21 patients treated definitively with radiation therapy alone were included in this study. The age of the patients ranged from 53 to 81 years with a median of 66 years. All the patients were male. The medical reasons for inoperability were lack of pulmonary reserve, cardiovascular disease, poor performance status, old age, and patient refusal in the decreasing order. Pathological evidence was not adequate to characterize the non-small cell subtype in two patients. Of the remaining 19 patients, 16 had squamous cell carcinoma and 3 had adenocarcinoma. Treatment was given with conventional fractionation, once a day, five times a week. The doses to the primary site ranged from 56 Gy to 69 Gy. No patients were lost to follow-up. The overall survival rates for the entire group at 2, 3 and 5 years were 41, 30 and 21%, respectively. The cause specific survivals at 2, 3 and 5 years were 55, 36 and 25%, respectively. An intercurrent disease was the cause of death in two patients. The cumulative local failure rate at 5 years was 43%. Nine of the 21 patients had treatment failures after the curative radiotherapy was attempted. Local recurrences as the first site of failure were documented in 7 patients. Therefore, local failure alone represented 78% of the total failures. Those patients whose tumor sizes were less than 4 cm had a significantly better 5 year disease free survival than those with tumors greater than 4 cm (0% vs 36%). Those patients with a Karnofsky performance status less than 70 did not differ significantly with respect to actuarial survival when compared to those with a status greater than 70

    The focus of human papilloma virus (HPV), particulary HPV 16 is on the role of carcinogenic and prognostic factors on oropharyngeal squamous carcinoma (OSCC). However, it remains unclear why patients with HPV-positive tumors have better outcomes than those with HPV-negative tumors. Thymidylate synthase (TS) is one of the initial key enzymes in the 5-fluouracil (5-FU) metabolic pathway. Clinical studies showed that intratumoural TS level was related to the response to 5-FU-based chemotherapy in patients with several types of cancer such as gastroenterological and head and neck cancers. We investigated the prevalence of HPV infection and TS expression in the patients with OSCC and evaluated the prognostic implications according to the HPV status and TS expression. We evaluated for high-risk HPV types (HPV 16, 18, 31, 33, 51, 52, 58) using a real-time polymerase chain reaction (RT-PCR) assay on archival biopsies from 54 patients with OSCC. Immunohistochemical assessments for TS were also performed. HPV was positive in 22 (40.7%) of 54 samples. Of these positive cases, 21 (95%) carried HPV 16 and only 1 (5%) HPV58 sequences. TS was overexpressed in 25 (46.3%) of 54 samples. Of these, 19 (76.0%) had an HPV-negative status and 21 (84.0%) were heavy smokers. TS overexpression was associated with the patients with HPV-negative tumors (P=0.02) and heavy smokers (p=0.012). Univariate analysis revealed that HPV positive status (77.3% vs. 29.0%; p=0.006) significantly improved overall survival. Conversely, no remarkable prognostic difference was observed on immunohistochemical analysis of TS expression. A multivariate analysis using Cox's proportional hazard model showed that early T stage (T1-2), early N stage (N0-1), and positive HPV status were significantly independent predictors for superior overall survival. Our studies suggested that positive HPV status was most strongly associated with a favorable prognosis in the patients with OSCC. TS expression has an unusual aspect

    Hepatocellular carcinoma (HCC) is the fifth most common neoplasm and the third leading cause of cancer-related deaths worldwide. Cirrhosis, most often due to viral hepatitis, is the predominant risk factors for HCC and geographical differences in both risk factors and incidence are largely due to epidemiological variations in hepatitis B and C infection. Hepatic function is a relevant parameter in selecting therapy in HCC. The current clinical classification of HCC split patients into 5 stages, with a specific treatment schedule for any stage. As patients with early stages can receive curative treatments, such as surgical resection, liver transplantation or local ablation, surveillance program in high-risk populations has become mandatory. Sorafenib, a multikinase inhibitor, has recently shown survival benefits in patients at advanced stage of disease. Hopefully, new molecular targeted therapies and their combination with sorafenib or interventional and surgical procedures, should expand the therapeutic armamentarium against HCC.

    Full Text Available Thyroid carcinoma is rare comprising 1% of all malignancies and commonly presents as a neck lump. Papillary thyroid carcinoma unlike follicular thyroid carcinoma tends not to metastasise to distant sites.We present a case of papillary thyroid carcinoma presenting as a solitary asymptomatic pelvic bone metastases and highlight current management of bone metastases. A 59-year old female was found on abdominal computerised tomography to have an incidental finding of a 4.5 cm soft tissue mass in the right iliac bone. Biopsy of the lesion confirmed metastatic thyroid carcinoma. There was no history of a neck lump, head and neck examination was normal. Further imaging confirmed focal activity in the right lobe of the thyroid. A total thyroidectomy and level VI neck dissection was performed and histology confirmed follicular variant of papillary carcinoma.Early detection of bone metastases have been shown to improve prognosis and thyroid carcinoma should be considered as a potential primary malignancy.

    Full Text Available Introduction: Oral squamous cell carcinoma (OSCC, which represents more than 90% of head and neck malignant neoplasms, has a poor prognosis due to its high frequency of lymph node metastasis and local invasion. Previous studies have investigated parameters related to the biological behavior of OSCC and its correlation with disease outcome (DO. Objective: To evaluate clinical and morphological data in cases of tongue squamous cell carcinoma (TSCC, correlating these findings with prognosis. Material and methods: Fifty-seven specimens of TSCC were obtained from patients undergoing surgical excision at a referral hospital in Natal, Brazil. Clinical data, such as tumor-node-metastasis (TNM stage and DO, were collected from medical records. Hematoxylin and eosin-stained sections were analyzed regarding histological grade of malignancy (HGM, based on the system proposed by Bryne (1998 Results: The majority of patients (38.6% were diagnosed as TNM stage III, and 57.9% developed metastases. Remission of the tumor occurred in 77.2% of the cases. The parameter “metastasis” exhibited a significant association with DO (p = 0 and TNM stage (p = 0.001, thus constituting a good indicator of tumor progression. Correlation of HGM and TNM stage with DO was not evidenced. Nevertheless, statistical analysis showed a significant association between HGM and TNM stage (p = 0.006. Conclusion: TNM clinical staging and HGM, evaluated in association, may be useful to estimate the prognosis of TSCC.

    The (131)I-iodide ((131)I) whole-body scan, for thyroid carcinoma is at times difficult to interpret. In a diagnostic whole body (131)I scan of a patient with follicular carcinoma, a posterior skull lesion was partially hidden by overlapping facial structures. On lateral head view, the abnormality was clearly evident. SPECT/CT and MRI showed the lesion originated in the occipital bone and had enlarged into the posterior fossa. The mass was surgically removed and the patient received (131)I therapy for residual tissue. The study demonstrates a pitfall in the reading of two dimensional radioiodine images which can be overcome by SPECT or lateral imaging. Copyright © 2013 Elsevier España, S.L. and SEMNIM.

    Metaplastic carcinoma of the breast is a rare tumor. The appearance of unexpected mesenchymal elements within the epithelial tumors is the squamous metaplasia. These tumors have a different clinical behaviour that classical breast carcinoma. We present a case of metaplastic mammary carcinoma with multiple relapses treated with a combination of chemotherapy and radiotherapy. The use of chemotherapy after local treatment has enhanced the relapse-free survival. The combined treatment modality seems to produce some benefit in the management of the local relapses of this neoplasms

    Hepatocellular carcinomas can be further divided into distinct subtypes that provide important clinical information and biological insights. These subtypes are distinct from growth patterns and are on based on morphologic and molecular findings. There are 12 reasonably well-defined subtypes as well as 6 provisional subtypes, together making up 35% of all hepatocellular carcinomas. These subtypes are discussed, with an emphasis on their definitions and the key morphologic findings. Copyright © 2017 Elsevier Inc. All rights reserved.

    Full Text Available Molecular magnetic resonance imaging targeted to an endothelial integrin involved in neoangiogenesis was compared to DCE-US and immunochemistry to assess the early response of three different therapeutic agents in renal cell carcinoma. Human A498 renal cells carcinoma was subcutaneously inoculated into 24 nude mice. Mice received either phosphate-buffered saline solution, sunitinib, everolimus, or bevacizumab during 4 days. DCE-US and molecular MRI targeting αvβ3 were performed at baseline and 4 days after treatment initiation. PI, AUC, relaxation rate variations ΔR2⁎, and percentage of vessels area quantified on CD31-stained microvessels were compared. Significant decreases were observed for PI and AUC parameters measured by DCE-US for bevacizumab group as early as 4 days, whereas molecular αvβ3-targeted MRI was able to detect significant changes in both bevacizumab and everolimus groups. Percentage of CD31-stained microvessels was significantly correlated with DCE-US parameters, PI (R=0.87, p=0.0003 and AUC (R=0.81, p=0.0013. The percentage of vessel tissue area was significantly reduced (p<0.01 in both sunitinib and bevacizumab groups. We report an early detection of neoangiogenesis modification after induction of targeted therapies, using DCE-US or αvβ3-targeted MRI. We consider these outcomes should encourage clinical trial developments to further evaluate the potential of this molecular MRI technique.

    Full Text Available Mitotane (o,p'-DDD acts mainly as an inhibitor of intramitochondrial pregnenolone and cortisol synthesis. Its adrenolytic effect depends on metabolic activation due to conversion to o,p'-DDA and o,p'-DDE. The drug has been used for 40 years in the treatment of adrenocortical carcinoma, mainly its regional and metastatic stage, as an adjuvant to surgical resection of the tumor. In the medical literature there are controversial opinions about its efficacy for the treatment of adrenocortical carcinoma. In our experience, mitotane administered immediately after surgery appeared to be much more efficient than when administered later. We have administered this drug in all cases of microscopically confirmed adrenocortical carcinoma, irrespectively of stage at the time of surgery, for fear of a false too optimistic classification. In our series of 82 patients with adrenocortical carcinoma, 59 patients have been treated with mitotane, 32 of them immediately after surgery, and 27 with a delay of 2 to 24 months. Today there are 18 survivors in the group of patients treated with mitotane soon after the operation and only 6 survivors in the group receiving mitotane with a delay. All patients were simultaneously given replacement therapy. Undesired effects of mitotane administration included increased aminotransferase and alkaline phosphatase activity, decreased white cell, platelet or red cell number, and myasthenia. Furthermore, we used mitotane with good results in Cushing's syndrome of non-malignant origin as pre-treatment before surgery or in long-term treatment for patients with poor tolerance of other adrenal inhibitors.

    Full Text Available Background and Objective: The role of (Human Papilloma Virus HPV in cancer of certain anatomical location, such as cervix, has been widely recognized. The present study was conducted to explore the association between HPV 16-E6 protein and esophageal squamous cell carcinoma. Methods: SP immunohistochemical method was used to examine the expression of HPV 16-E6 in 50 cases of esophageal squamous cell carcinoma, 10 cases of normal esophageal squamous cell and 10 cases of adjacent tissue. Results: The expression of HPV 16-E6 was significantly higher in esophageal carcinoma than in normal esophageal mucosa and in adjacent tissue. The expressions of HPV 16-E6 had significant correlation with invasive depth (P<0.05, but not with patient age, lymph node metastasis, tumor size (P>0.05. Conclusion: HPV 16-E6 can promote the growth and metastasis of esophageal squamous cell carcinoma and can be a prognostic factor of esophageal squamous cell carcinoma.DOI: http://dx.doi.org/10.3126/jcmsn.v10i4.12970 JCMS Nepal 2014; 10(4:1-5

    To establish the correlation between tumor appearance on CT and tumor histology in renal cell carcinomas. The density and attenuation patterns of 96 renal cell carcinomas, each ≤5 cm in greatest diameter, were studied by non-enhanced CT and early and late after bolus injection of contrast medium using dynamic CT. The density and attenuation patterns and pathological maps of each tumor were individually correlated. High attenuated areas were present in 72 of the 96 tumors on early enhanced dynamic CT scanning. All 72 high attenuated areas were of the clear cell renal cell carcinoma and had alveolar architecture. The remaining 24 tumors that did not demonstrate high attenuated foci on early enhanced scanning included three clear cell, nine granular cell, six papillary, five chromophobe and one collecting duct type. With respect to tumor architecture, all clear cell tumors of alveolar architecture demonstrated high attenuation on early enhanced scanning. Clear cell renal cell carcinomas of alveolar architecture show high attenuation on early enhanced dynamic CT scanning. A larger number of patients are indispensable to obtaining clear results. However, these findings seem to be an important clue to the diagnosis of renal cell carcinomas as having an alveolar structure. (author)

    Full Text Available Abstract Background Hepatocellular carcinoma (HCC is the third-leading cause of cancer-related deaths worldwide. It is often diagnosed at an advanced stage, and hence typically has a poor prognosis. To identify distinct molecular mechanisms for early HCC we developed a rat model of liver regeneration post-hepatectomy, as well as liver cells undergoing malignant transformation and compared them to normal liver using a microarray approach. Subsequently, we performed cross-species comparative analysis coupled with copy number alterations (CNA of independent early human HCC microarray studies to facilitate the identification of critical regulatory modules conserved across species. Results We identified 35 signature genes conserved across species, and shared among different types of early human HCCs. Over 70% of signature genes were cancer-related, and more than 50% of the conserved genes were mapped to human genomic CNA regions. Functional annotation revealed genes already implicated in HCC, as well as novel genes which were not previously reported in liver tumors. A subset of differentially expressed genes was validated using quantitative RT-PCR. Concordance was also confirmed for a significant number of genes and pathways in five independent validation microarray datasets. Our results indicated alterations in a number of cancer related pathways, including p53, p38 MAPK, ERK/MAPK, PI3K/AKT, and TGF-β signaling pathways, and potential critical regulatory role of MYC, ERBB2, HNF4A, and SMAD3 for early HCC transformation. Conclusions The integrative analysis of transcriptional deregulation, genomic CNA and comparative cross species analysis brings new insights into the molecular profile of early hepatoma formation. This approach may lead to robust biomarkers for the detection of early human HCC.

    The literature recognises a relationship between clinical experience and a successful undergraduate experience in nursing; however what constitutes an effective approach remains the subject of debate, particularly in relation to first year of learning. There is evidence from a biological standpoint that early experience impacts on the behavioural development of animals, described by Konrad Lorenz (1903-1989) as 'imprinting'. The concept of imprinting has resonance for nursing. In this article the importance of 'getting it right at the beginning' is explored and what, if anything, Lorenz's theory tells us about the impact of early clinical learning on subsequent professional development.

    Forty-three cases of primary vaginal squamous cell cancer were treated at the University of Wisconsin Hospital between 1956 and 1971. These cases comprised of 1.2% of patients admitted to the University Hospital with female genital tract cancer. Evidence is presented to support a modification of the currently accepted FIGO staging system for vaginal carcinoma (Stage II disease). Radiation therapy using both external beam and brachyradium equivalents or interstitial implantation of suitable isotopes was an effective method for the treatment of patients having early and locally advanced invasive vaginal cancer. The 5-year absolute survival rate for the entire series was 37.2%. Absolute survival rate by modified FIGO clinical staging was 66% for Stages I and IIA, 31% for Stage IIB, 25% for Stage III, and 0% for Stage IV

    Barium Enema study for colon examination is of great importance in the health care of our people and its value can be increased by a wide understanding of the attendant difficulties and limitation. Since the incidence of the colon and rectal carcinoma is increasing, the barium enema examination is more valuable. Radiologically diagnosed 134 cases of colon and rectal carcinoma from January 1964 to June 1970 have been reviewed at Yensei Univ., College of Medicine. Among the total admission during these years, the ratio of the colon and rectal carcinoma was 0.29 percent, and the incidence among barium enema examination was 5.3%. The peak age range was between 40 and 50 years. The average age of the patients was 46 years. It was more common in male. The clinical picture was rather vague in some cases, especially in the lesions of right colon. The large number of cases has bowel habit change, tarry or bloody stool and abdominal pain. About 60% of the lesions were located in rectum and 40% was proximal portion from the rectum, which could not be completely diagnosed only by digital examination and proctosigmoidoscopy. On roentgenogram, the most common form was encircling type, next was fungating. The positivity for accuracy of the barium enema examination was 90%. Majority of cancers of the colon, particularly those that produce symptoms are relative gross lesions. In daily practise we have to eager to find out small lesions by repeat and complete barium enema examination, including double contrast study. Early diagnosis is an aid immediate, logical objective in attempts to decrease the morbidity and mortality from carcinoma of colon.

    Although well established in chronic schizophrenia, the key determinants of functioning remain unknown during the early phase of a psychotic disorder. The aim of this study was to comprehensively examine the social cognitive, basic neurocognitive and clinical predictors of concurrent social functioning and global functioning in an early psychosis sample. This study examined the relationship between social cognition, basic neurocognition and clinical symptoms with concurrent functioning in 51 early psychosis individuals. Assessments included a range of self-report, observational and clinician-rated measures of cognitive, symptom severity and functioning domains. Results revealed a significant association between self-reported social function and lower levels of both social interaction anxiety and negative psychotic symptoms. A significant association was also observed between lower levels of negative psychotic symptoms and observed social functioning. Lastly, results demonstrated a significant association between reduced negative psychotic symptoms and clinician-rated global functioning. Clinical domains such as negative symptoms and social interaction anxiety significantly contribute to an optimal model predicting outcome during the early phase of a psychotic disorder. These clinical features may also provide useful markers of an individual's capacity for social participation. Clinical implications include the need for early targeted intervention to address social anxiety and negative psychotic symptoms to facilitate optimum patient outcome. © 2015 Wiley Publishing Asia Pty Ltd.

    Primary carcinoma with osteoclast-like giant cells is a very rare tumour of the female breast. The clinical course, histological, immunohistochemical and ultrastructural features of 61 cases of invasive duct carcinoma with osteoclast-like multinucleated giant cells (OMGCs) are reviewed and a new...... in the literature have shown that 86% of patients with these tumours are still alive after 5 years. Histologically, these tumours are invasive ductal carcinomas with OMGCs next to the neoplastic glands and within their lumen. Signs of recent and past haemorrhage are ubiquitously present in the highly vascularized...

    Despite significant investments in the development of new agents only 5% of cancer drugs entering Phase I clinical trials are ultimately approved for routine clinical cancer care. Drug repurposing strategies using novel combinations of previously tested anticancer agents could reduce the cost and improve treatment outcomes. At MD Anderson Cancer Center, early phase clinical trials with drug repurposing strategies demonstrated promising outcomes in patients with both rare and common treatment refractory advanced cancers. Despite clinical efficacy advancing drug repurposing strategies in the clinical trial trajectory beyond early phase studies has been challenging mainly due to lack of funding and interest from the pharmaceutical industry. In this review, we delineate our experience and challenges with drug repurposing strategies.

    The prospective study was carried out on 183 patients with histologically proven breast cancer received at Khartoum Teaching Hospital and Soba Hospital between January 1996 to May 1998. Most of the patients were from Khartoum State followed by patients coming from Western, Central and Northern states with incidence of 17%, 16% and 15% respectively. Gaalein, shaigia, mahas and rizigat were the commonest affected tribes in western Sudan. Few patients were from southern and northern Sudan. Genetic and environmental factors may be contributory factors. The incidence of male breast cancer was 3%, which is higher than that reported in the western world. In this study young age group, early menarche, late first pregnancy and nulliparity were the main risk factors. The multiparity, lactation and lack of positive family history did not protect our patients from developing breast cancer. Most of the patients presented with locally advanced for the disease. This is due to the aggressive nature of breast cancer among black population. Lung, bone and liver were the most frequent sites for metastases. Chest x-ray and skeletal survey were diagnostic of metastases. Ductal carcinoma was the commonest type of breast cancer in this study. Laboratory investigations in the form of full blood count, liver function test , blood urea and serum electrolytes have no prognostic value in our patients.(Author)

  9. Temporal lobe and hypothalmic-pituitary dysfunctions after radiotherapy for nasopharyngeal carcinoma: a distinct clinical syndrome

    1988-01-01

    Eleven patients with combined neurological and endocrine complications after external radiotherapy for nasopharyngeal carcinoma are described. Memory disturbance, complex partial seizures and hypodense areas in one or both temporal lobes on CT were typical features. Endocrinologically, hypopituitarism was the prominent manifestation. This constellation of clinical features in a patient with previous radiotherapy to the nasopharynx characterises radiation injury to the inferomedial aspects of the temporal lobes and the hypothalamic-pituitary axis. While parenchymal brain lesions may mimic metastases or glioma on CT, associated endocrine disturbance would betray the correct diagnosis. The importance of recognising hypo-pituitarism which may be clinically asymptomatic and which is amenable to therapy is emphasised, as is the need for a proper fractionation of radiation dose to minimise the incidence of these disabling complications.

    Sinonasal carcinomas are rare tumours with an unfavourable prognosis whose management is difficult and complex, leading to high morbidity and mortality despite improvements in the field of surgery and radiotherapy. An elevated number of these tumours can be attributed to occupational exposure. In comparison with other head and neck malignancies, studies of molecular changes in these tumours are infrequent. This review was focused on findings about the epidemiology and molecular and phenotypic characterisation of sinonasal carcinomas, which can potentially be useful for diagnosis and treatment. The increasing knowledge about the molecular biology that underlies their carcinogenesis may help to identify precursor lesions, prognostic markers and markers that predict chemoradiotherapy response and, finally, to identify potential molecular targets that will expand treatment options.

    Full Text Available Small cell carcinoma of the esophagus is a rare tumor described to the first time by Mckeown in 1952. Clinically it is very similar to small cell carcinoma of the lung. with quick evolution and early dissemination.It is more frequent in men between 60 and 70 years of age. The patients usually have dysphagia and weight loss. Most of the tumours arise in the middle and distal third of the esophagus. Chronic alcohol and tobacco use are usually present. The manegement of primary small cell cancer of the esophagus remains controversial with groups reporting treatment based on operation alone, local radiotherapy, chemotherapyalone, or operation with adjuvant therapy. Overall survivel remains poor at a mean of 5.1 months, with the best rate of survivel in patients undergoing operation with adjuvant chemotherapy. The authors relate two cases of a small cell carcinoma of the esophagus. Both of these patients was female and white, with 51 and 64 years old. The first mainestation was dysphagia and weight loss. Histologic study from endoscopic biopsies reveled the diagnosis. The treatment was, in the both cases surgery, however in one case, chemotherapy and mediastinal irradiation was associated to the ressection. The authors comment the more important aspects about this pathology and the treatment and survival of the patients.

    To examine expression of the connective tissue growth factor (CTGF) gene in human thyroid cancer and establish whether a correlation exists between the presence of CTGF protein and clinicopathological parameters of the disease. CTGF protein expression was investigated retrospectively by immunohistochemical analysis of CTGF protein levels in thyroid tumour tissue. Associations between immunohistochemical score and several clinicopathological parameters were examined. In total, 131 thyroid tissue specimens were included. High levels of CTGF protein were observed in papillary thyroid carcinoma tissue; benign thyroid tumour tissue scored negatively for CTGF protein. In papillary thyroid carcinoma, there was a significant relationship between high CTGF protein levels and Union for International Cancer Control disease stage III-IV, and presence of lymph node metastasis. In papillary thyroid carcinomas, CTGF protein levels were not significantly associated with sex or age. These findings suggest that the CTGF protein level is increased in papillary thyroid carcinoma cells compared with benign thyroid tumours. CTGF expression might play a role in the development of malignant tumours in the thyroid.

    Esophageal cancer is a common malignancy with a very poor prognosis. Successful strategies for primary prevention and early detection are critically needed to control this disease. Multiphoton microscopy (MPM) is becoming a novel optical tool of choice for imaging tissue architecture and cellular morphology by two-photon excited fluorescence. In this study, we used MPM to image microstructure of human normal esophagus, carcinoma in situ (CIS), and early invasive carcinoma in order to establish the morphological features to differentiate these tissues. The diagnostic features such as the appearance of cancerous cells, the significant loss of stroma, the absence of the basement membrane were extracted to distinguish between normal and cancerous esophagus tissue. These results correlated well with the paired histological findings. With the advancement of clinically miniaturized MPM and the multi-photon probe, combining MPM with standard endoscopy will therefore allow us to make a real-time in vivo diagnosis of early esophageal cancer at the cellular level.

    Objective To study the expressions of RNA-binding Ras-GAP SH3 binding protein (G3BP) and tumor stem cell marker CD44v6 in laryngeal squamous cell carcinoma and their correlations with angiogenesis. Methods We collected the cancer tissues and corresponding paracancerous tissues from 56 patients with laryngeal squamous cell carcinoma. The expressions of G3BP and CD44v6 proteins were detected by Western blotting in cancer tissues and corresponding paracancerous tissues; the expressions of G3BP, CD44v6 and vascular endothelial growth factor A (VEGF-A) were tested by immunohistochemistry. Thereafter, we compared the positive expression rates of G3BP and CD44v6 between in cancer tissues and in normal tissues, analyzed the correlations between the expressions of G3BP, CD44v6 and the laryngeal squamous cell carcinoma features as well as their correlations with microvessel density (MVD) that was determined by FVIIIAg immunohistochemistry. Results Western blotting showed that the expressions of G3BP and CD44v6 proteins in the laryngeal squamous cell carcinoma were higher than those in the paracancerous tissues. Immunohistochemistry showed that compared with the paracancerous tissues, G3BP, CD44v6 and VEGF-A expressions (the positive rates are 58.9%, 53.6%, 46.4%, respectively) were higher in cancer tissues. The positive rates of G3BP and CD44v6 in cancer tissues were related with the clinical stage, recurrence or metastasis, and lymph node metastasis of laryngeal squamous cell carcinoma, but had nothing to do with patients' age and tumor size. Pearson correlation analysis showed the expressions of both G3BP and CD44v6 were positively correlated with VEGF-A (r=0.741, r=0.756). MVD values were significantly higher in the G3BP and CD44v6 positive cases than in paracancerous tissues, but there was no difference in MVD between those without G3BP and CD44v6 positive expressions and the paracancerous tissues. Conclusion The positive expression rates of G3BP and CD44v6 in laryngeal

    We studied whether patients with seropositivity in early rheumatoid arthritis (RA) comprise a different clinical group than those with seronegativity. Four hundred seventeen patients with early RA according to the American College of Rheumatology criteria (disease duration less than 1 year) were retrospectively studied by analysis of demographic, clinical, laboratory, radiological, and therapeutic disease characteristics from the time of diagnosis until the end of the study period (1981 1999) using a data base. There were 248 seropositive patients and 169 seronegative patients with RA. No statistically significant differences were seen between the two groups before commencement of the study period in relation to age of disease onset, male:female ratio, and disease duration. However, seropositive patients showed longer medical follow-up. In addition, at disease onset, seropositive RA patients presented more frequently with symmetrical polyarthritis and small joint involvement than seronegative patients. The seropositive group also had more tender and swollen joints, weaker grip strength, and higher erythrocyte sedimentation and C-reactive protein rates during the follow-up period. In contrast, the seronegative group had less severe radiological findings and greater functional ability at the end of the study. In Greek patients with early RA, rheumatoid factor seems to be a predictor of more severe disease activity.

    Objective: To research the early effects and side-effects of the local advanced nasopharyngeal carcinoma patients using intensity-modulated radiotherapy (IMRT) combined with concurrent chemotherapy. Methods: From January 2005 to January 2007, 60 patients with nasopharyngeal carcinoma of stage m-IV b were received IMRT combined with concurrent chemotherapy in our center. Sixty patients were divided into paclitaxel concurrent group (32 patients) and cisplatin concurrent group (28 patients). The prescribing doses of the primary tumor were 68-72 Gy for each group. The patients of paclitaxel concurrent group received 5-7 times pacitaxel liposome chemotherapy of 30 mg · m -2 ·. The patients of cisplatin concurrent group received 5-7 times cisplatin chemotherapy of 30 mg · m -2 · week -1 . Results: As to the side-effects, the patients of the cisplatin concurrent group got earlier radiodermatitis and radiation-induced mucositis but also got significantly higher rate of radiodermatitis, radiation-induced mucositis, radiation-induced leucopenia and gastrointestinal toxicity, as well as the loss of weight. No significant difference was found on liver and renal functions between two groups.Four patients (12.5%) of the paclitaxel concurrent group were broken-off, which was much better than the cisplatin concurrent group. There was no significant difference on the specific length of break-off time, the 2-year overall survival rate and the 2-year diseaee-free survival rate between two groups. Conclusions: IMRT combined with concurrent chemotherapy of paclitaxel liposome for local advanced nasopharyngeal carcinoma results in less side-effects and better tolerance than IMRT combined with concurrent cisplatin chemotherapy.

    In the mid-nineteenth century, photographers used mirrors to document different views of a patient in the same image. The first clinical photographs were taken by portrait photographers. As conventions for clinical photography were not yet established, early clinical photographs resemble contemporary portraits. The use of mirrors in clinical photography probably originated from the portrait studios, as several renowned photographers employed mirrors in their studio portraits. Clinical photographs taken for the US Army Medical Museum between 1862 and 1882 show different ways of employing this mirror technique.

    For inoperable bronchial carcinomas the prognostication is unfavourable still in this era of combined radiological and chemical therapy. Yet the situation is better than it was two years ago. Important international therapeutical investigations have substantially enriched our knowledge. This concerns first of all parvicellular anaplastic carcinomas of the bronchi where, thanks to the combination chemotherapy-radiotherapy-chemotherapy, new possibilities have turned up and the radiotherapy of the primary tumor, the mediastinum and the neurocranium has become firmly established in spite of initial scepticism. As regards non-parvicellular carcinomas, the development is still behind. Post-operative radiotherapy occupies a place in the non-curative resection of bronchial carcinomas. As to the rest, the radiotherapist encounters only palliative indications at the moment excepting controlled clinical studies. It is to be hoped that new combination therapies including hyperthermal measures, radiosensitizer, bleomycin and other chemotherapeuticals will open up now paths. Supraregional therapeutical investigations should be initialled in this sector.

    Fibrolamellar carcinoma (FLC) has been considered a distinct clinical entity vs. hepatocellular carcinoma, with respect to its epidemiology, etiology, and prognosis. We describe the unusual case of a 23-year-old female patient with FLC and ovarian (Krukenberg) and peritoneal metastases, clinically mimicking an ovarian carcinoma. Multiple recurrences occurred despite initial R0 resection and chemotherapy, requiring surgical treatment. The patient survived five years and died from generalized disease. The particularities of our case are discussed by comparison with the other two similar cases and other date from the literature. To our knowledge, the ovarian involvement encountered in our case is the third case published in literature, being explained by the superficial location of the liver tumor.

    2012-01-01

    Nipple discharge (ND) can be the earliest presenting symptom of breast cancer. We hereby present two cases of breast cancer with no palpable mass manifesting as isolated ND, which was whitish in color. In both cases, cytology of the discharge revealed highly pleomorphic cells indicating a high grade malignancy. Mammography showed diffuse, extensive microcalcifications. Simple mastectomy with axillary clearance was done. Histology in both cases revealed diffusely spreading intraductal carcinoma, with focus of microinvasion in one case. ND if scanty or not blood stained is often ignored by the patients and at times, the clinicians. This article highlights that ND can be an early warning sign of intraductal carcinomas that are non-invasive in early stage. Irrespective of the color or nature of the discharge, unilateral ND needs to be evaluated. Proper clinical assessment, cytological evaluation of the ND, and mammography ought to be performed in all such cases. Considering the low level of awareness in women regarding the warning signs of breast cancer, the current focus is to create “breast awareness.” Women should be sensitized to recognize any unusual changes in their breasts and report to their health care providers at the earliest.

    2016-01-01

    Chronic hepatitis B virus (HBV) infected patients have an almost 100-fold increased risk to develop hepatocellular carcinoma (HCC). HCC is the fifth most common and third most deadly cancer worldwide. Up to 50% of newly diagnosed HCC cases are attributed to HBV infection. Early detection improves survival and can be achieved through regular screening. Six-monthly abdominal ultrasound, either alone or in combination with alpha-fetoprotein serum levels, has been widely endorsed for this purpose. Both techniques however yield limited diagnostic accuracy, which is not improved when they are combined. Alternative circulating or histological markers to predict or diagnose HCC are therefore urgently needed. Recent advances in systems biology technologies have enabled the identification of several new putative circulating biomarkers. Although results from studies assessing combinations of these biomarkers are promising, evidence for their clinical utility remains low. In addition, most of the studies conducted so far show limitations in design. Attention must be paid for instance to different ethnicities and different etiologies when studying biomarkers for hepatocellular carcinoma. This review provides an overview on the current understandings and recent progress in the field of diagnostic and predictive circulating biomarkers for hepatocellular carcinoma in chronically infected HBV patients and discusses the future prospects.

    Sputum cytology examination is the most effective method to detect early stage central type squamous cell carcinoma. As sputum-positive early stage lung cancer usually does not show any abnormal findings on chest X-ray film, fiberoptic bronchoscopy is subsequently performed for localization. However, sometimes cases do not show any abnormal findings of cancer endoscopically because they are very early stage cases. For the purpose of localization of invisible lesions the photodynamic reaction was employed in this study. Photodynamic reaction is achieved by transfer of energy of an excited photo-sensitizer induced by photoradiation of light. This phenomenon was already recognized in the beginning of this century. Study of tumor localization of the bronchial tree using hematoporphyrin derivative (HpD) and a mercury arc lamp was first performed in the Mayo Clinic in 1960s. In 1978, krypton laser was used first as a light source by Profio and Doiron. Authors have been doing research on early localization of such endoscopically occult early lung cancer since 1978. They recently developed an image processing system using an excimer dye laser for early localization of lung cancer. (author). 5 refs., 4 figs., 1 tab

    The Aim of this level 3 good clinical practice guideline is to help physicians, women and patients in decision making about the appropriate health care for early detection of breast cancer. The principle of early detection of breast cancer comprise the detection and diagnosis of premalignant breast tumors (stage 0, Carcinoma in situ), risk reduction of cancer development as well as the detection and diagnosis of breast cancer at an early stage (stage I), with a 90% chance of cure as shown by a large number of clinical trials. To establish a nation wide, comprehensive quality assuring program for the early detection of breast cancer the guideline summarized in the following paper offers the basis for a timely mortality reduction of breast cancer. The cure of early stage disease will be additionally possible by less invasive treatment allowing patients to maintain quality of life. The guideline leads to a major improvement of women's health care. (orig.) [de

    A case of clear cell carcinoma of the endometrium following squamous cell carcinoma of the cervix is reported. The patient had had a previous cervical biopsy which revealed squamous cell carcinoma (large cell non-keratinizing type), classified clinically as a stage IIb lesion. She was treated with external pelvic irradiation delivering an estimated tumor dose of approximately 7,000 rads and intracavital radium application delivering 4,995 mg.hr.radiation when she was 51 years old. She complained of post-menopausal bleeding at age 66 and was diagnosed by endometrial cytology as having clear cell carcinoma of the endometrium. Total abdominal hysterectomy, bilateral salpingo-oophorectomy and omentectomy were performed. The clinical stage of the endometrial cancer was Ib. She is alive after 2 years with no evidence of disease. Endometrial cytology revealed several adenocarcinoma cells in small clusters. The shape of the nuclei was somewhat irregular, the chromatin pattern was fine granular, and single or multiple nucleoli were seen. The diameter of these nuclei ranged from 10 to 30 {mu}m. The cytoplasm was pale green or vacuolated. The volume of the cytoplasm varied from scanty to abundant. These findings suggested clear cell carcinoma. Histopathologically, an irregular shaped polypoid tumor, 3 x 1.5 cm in size, was located on the lower anterior wall of the uterine corpus. The tumor was a clear cell carcinoma showing a solid and papillary pattern. A hobnail pattern was not observed. The cytoplasm was clear and abundant, and PAS-positive granules digestible by diastase were seen. These 2 cancers had different pathological features and their immunohistochemical reactivities for CEA and keratin were also different. The patient was regarded as having a rare heterochronous double cancer consisting of squamous cell carcinoma of the cervix and clear cell carcinoma of the endometrium. (author).

    Full Text Available Background: Stomach cancer is one of the leading causes of cancer death. The grading and staging of this cancer plays an important prognostic role. Lymphovascular invasion predicts poor outcome in gastric cancer. Among the others, lymphovascular invasion provides useful information for the clinical management of patients with gastric cancer. Nevertheless, data about lymphovascular invasion in early-stage and in lymph node-positive gastric cancer are lacking. Hence, significance of lymphovascular invasion to metastatic lymph nodes impacting nodal status in gastric cancer has been studied in this study.Materials and methods: This is a retrospective analysis of twenty nine (29 histologically confirmed gastric carcinoma cases received in the department of Pathology at NMCTH dating from October 2014 to September 2016.Results:  There was male preponderance to gastric carcinoma with male to female ratio of 2.2:1. The age varied from 31- 84 years. There were 17 cases (59% of intestinal type and 11 cases (38% of diffuse type of gastric carcinoma and 1 case (3% of adeno-neuroendocrine carcinoma. Microscopic evaluation for depth of invasion showed tumor invasion till the subserosal connective tissue layer (69% suggesting pT3 stage.  lymphovascular invasion was identified in 21 cases (72%. There was statistically significant correlation (p value 0.01 between   lymphovascular invasion and nodal status (N0 status. Conclusion: Presence of lymphovascular invasion is considered as poor prognostic marker in case of gastric adenocarcinoma. Pathologist have been reporting their presence or absence in each gastrectomy reports related to gastric carcinoma.This study has established a significant relation between presence of lymphovascular invasion and nodal staging of gastric carcinoma.

    Skull base metastasis from differentiated thyroid carcinoma including follicular thyroid carcinoma (FTC) and papillary thyroid carcinoma (PTC) is a rare clinical entity. Eighteen FTC cases and 10 PTC cases showing skull base metastasis have been reported. The most common symptom of skull base metastasis from FTC and PTC is cranial nerve dysfunction. Bone destruction and local invasion to the surrounding soft tissues are common on radiological imaging. Skull base metastases can be the initial clinical presentation of FTC and PTC in the presence of silent primary sites. The possibility of skull base metastasis from FTC and PTC should be considered in patients with the clinical symptoms of cranial nerve dysfunction and radiological findings of bone destruction. A variety of genetic alterations in thyroid tumors have been identified to have a fundamental role in their tumorigenesis. Molecular histochemical studies are useful for elucidating the histopathological features of thyroid carcinoma. Recent molecular findings may provide novel molecular-based treatment strategies for thyroid carcinoma

    Metastatic renal cell carcinoma of the nasopharynx, nasal cavity, and paranasal sinuses can be misdiagnosed as primary malignant or benign diseases. A 33-year-old male attended our outpatient clinic complaining of difficulty breathing through the nose, bloody nasal discharge, postnasal drop, snoring, and discharge of phlegm. Endoscopic nasopharyngeal examination showed a vascularized nasopharyngeal mass. Under general anesthesia, multiple punch biopsies were taken from the nasopharynx. Pathologically, the tumor cells had clear cytoplasm and were arranged in a trabecular pattern lined by a layer of endothelial cells. After the initial pathological examination, the pathologist requested more information about the patient's clinical status. A careful history revealed that the patient had undergone left a nephrectomy for a kidney mass diagnosed as renal cell carcinoma 3 years earlier. Subsequently, nasopharyngeal metastatic renal cell carcinoma was diagnosed by immunohistochemical staining with CD10 and vimentin. Radiotherapy was recommended for treatment.

    sup(99m)Tc-phytate and /sup 67/Ga-citrate scintigraphies were evaluated clinically in 50 cases of histologically proven hepatocellular carcinoma. Detectability was higher in sup(99m)Tc-phytate scans than in /sup 67/Ga scans, and was influenced by the presence of liver cirrhosis. However, by using both scans, the highest detectability was obtained. /sup 67/Ga scan was useful especially in cases with equivocal sup(99m)Tc-phytate scintigraphy and cases with liver cirrhosis. There was no definite correlation seen between Edmondson's histological gradings and grades of /sup 67/Ga accumulation. No significant difference of /sup 67/Ga accumulation in hepatocellular carcinoma was observed regardless of the presence of liver cirrhosis. We conclude that it is better to use sup(99m)Tc-phytate as the first choice in screening of hepatocellular carcinoma and subsequent /sup 67/Ga scan if indicated.

    Nevoid basal cell carcinoma syndrome (NBCCS), which is also known by other names, including Gorlin-Goltz syndrome and multiple basal-cell carcinoma (BCC) syndrome, is a rare multi-systemic disease inherited in a dominant autosomal manner with complete penetrance and variable expressivity. The main clinical manifestations include multiple BCCs, odontogenic keratocysts of the jaw, hyperkeratosis of the palms and soles, skeletal abnormalities, intracranial calcifications and facial deformities. A 31-year-old male diagnosed with Gorlin-Goltz syndrome with multiple unresectable facial BCCs was treated with the Hedgehog inhibitor vismodegib. After one month of therapy on vismodegib, there were significant reductions in the size of multiple BCCs on the patient's face. The patient remains on this therapy. Hedgehog pathway inhibition is an effective strategy to treat unresectable BCCs from Gorlin-Goltz syndrome. Although vismodegib shows some promising clinical results in the early phase of its use, there are concerns of possible resistance developing within months. Duration of therapy, role of maintenance treatment and drug modification to reduce resistance need to be explored in future case studies.

    Basal cell carcinoma (BCC) is the most common type of skin cancer, which is highly damaging to the skin at its advanced stages and causes huge costs on the healthcare system. However, most types of BCC are easily curable if detected at early stage. Due to limited access to dermatologists and expert physicians, non-invasive computer-aided diagnosis is a viable option for skin cancer screening. A clinical biomarker of cancerous tumors is increased vascularization and excess blood flow. In this paper, we present a computer-aided technique to differentiate cancerous skin tumors from benign lesions based on vascular characteristics of the lesions. Dermoscopy image of the lesion is first decomposed using independent component analysis of the RGB channels to derive melanin and hemoglobin maps. A novel set of clinically inspired features and ratiometric measurements are then extracted from each map to characterize the vascular properties and blood content of the lesion. The feature set is then fed into a random forest classifier. Over a dataset of 664 skin lesions, the proposed method achieved an area under ROC curve of 0.832 in a 10-fold cross validation for differentiating basal cell carcinomas from benign lesions.

    Full Text Available Gastric outlet obstruction is defined as a clinical and patho - physiological consequence of any disease process that produces a mechanical impediment to gastric emptying which may be extrinsic or intrinsic. Gastric outlet obstruction can be a diagnostic and treatment dilemma. Endoscopy of upper gastrointestinal tract has been a sensitive and specific investigation to study the status of gastric outlet - the pylorus and has enabled early detection of lesions of both stomach a nd duodenum. We undertook a prospective clinical study regarding incidence, etiology, investigation and management of cases of Gastric outlet obstruction in adults in a period of three years. In our study the m ost common cause of GOO is Carcinoma stomach a ntral region 46.6% , duodenal ulcer 33.3% , corrosive acid ingestion sequel 8.3%, peri ampullary carcinoma 6.6%, Ca pancreas 3.3%% , cholangio Carcinoma 1.6%. Males are more commonly involved in a ratio of M: F=3:1. Surgical procedures done varied from defini tive resections to palliative bypass or feeding jejunostomy for enteral feeding

    Purpose: To analyze the outcomes of patients with early hypopharyngeal cancer treated with radical radiotherapy (RT). Methods and Materials: Ten institutions combined the data from 115 patients with Stage I-II hypopharyngeal squamous cell carcinoma treated with definitive RT between 1990 and 2001. The median patient age was 67 years; 99 patients were men and 16 were women. Of the 115 patients, 39 had Stage I and 76 had Stage II disease. Conventional fractionation was used in 98 patients and twice-daily RT in 17 patients; chemotherapy was combined with RT in 57 patients. The median follow-up period was 47 months. Results: The overall and disease-specific 5-year survival rate for 95 patients without synchronous malignancies was 66.0% and 77.4%, respectively. The 5-year disease-specific survival rate by T stage was 95.8% for patients with T1 disease and 70.1% for patients with T2 disease (p = 0.02). Of the 115 patients, local control with laryngeal voice preservation was achieved in 34 of 39 patients with T1 lesions, including 7 patients successfully salvaged, and in 56 of 76 patients with T2 lesions. Sixty-five patients (56.5%) had synchronous or metachronous cancers. Of the 115 patients, 19 died of hypopharyngeal cancer, 10 died of second primary cancers, and 14 died of other causes during the study and follow-up periods. Conclusions: Patients with early hypopharyngeal cancer tended to have a good prognosis after RT. However, second malignancies had an adverse effect on the overall outcomes of patients with early hypopharyngeal cancer
