    Background Multidetector computed tomography (MDCT) is widely accepted as an effective imaging modality in monitoring for bladder cancer recurrence after radical cystectomy. Elucidating the pattern of bladder cancer recurrence on CT can increase the diagnostic accuracy. Purpose To evaluate the recurrence patterns of transitional cell carcinoma of the bladder and the factors associated with cancer recurrence. Material and Methods One hundred and forty-nine consecutive patients (mean age, 66.55 years; range, 32-86 years) who underwent preoperative contrast-enhanced CT and radical cystectomy were included in this study. The presence, site, and time of tumor recurrence were recorded retrospectively by two radiologists in a consensus fashion. The association of tumor recurrence and tumor factors (T stage, lymph node metastasis, nuclear grade, and tumor diameter) were also evaluated using multiple logistic regression analysis and Kaplan-Meier statistics. Results Tumor recurrence occurred in 60 patients (40.3%) with a mean time of 14 months (range, 1-64 months). The sites of recurrence included the operation site (n = 20), lymph node (n = 20), bone (n = 11), liver (n = 6), lung (n = 5), upper urinary tract (n = 4), colon (n = 3), adrenal gland (n = 2), peritoneum (n = 1), abdominal wall (n = 1), psoas muscle (n = 1), and penile skin (n = 1). Tumor recurrence was found to be associated with advanced T stage (P = 0.002) and lymph node metastasis (P < 0.001). Conclusion Transitional cell carcinomas of the bladder recur more frequently at the operation site and lymph node, and T-stage and lymph node metastasis are closely associated with tumor recurrence.

    Full Text Available This paper was based in data survey from macro and microscopic oral lesions characteristics, personal data and medical history of patients diagnosed with oral squamous cell carcinoma in the Lab of Pathological Anatomy from the Federal University of Alfenas from January 2000 to December 2010, establishing comparative parameters among clinical data, type of treatment, recurrence, survival and anatomic pathological characteristics of the lesions. Were analyzed the histopathological reports, dental and hospital records. The highest incidence was in white men, age between 50 and 60 years, married, with low education and socioeconomic levels. The beginning of treatment occurred in average 67 days after the histopathological diagnosis. The estimated survival of patients at five years was 42%. The consumption of alcohol and tobacco and the occurrence of metastasis were statistically significant for the increase of recurrence and lethality.

    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 b...

    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.

    Patients with metachronous bilateral renal cell carcinoma pose a significant challenge given the high mortality of renal cell carcinoma and the poor quality of life should dialysis become necessary. In addition, patients may be subject to morbidity due to potential multiple treatments of the multifocal renal tumors. We present the case of a 71-year-old woman with multifocal, bilateral clear cell carcinoma who maintained a minimal change in serum creatinine after undergoing unilateral radical nephrectomy, subsequent percutaneous radiofrequency ablation, percutaneous cryoablation, laparoscopic cryoablation, and open partial nephrectomy for recurrent renal cell carcinoma in a solitary kidney.

    BACKGROUND The best way to approach surgically removed basal cell carcinoma with positive histopathological margins is a controversial issue. Some authors believe that the more appropriate treatment is an immediate reoperation while others prefer a periodic follow up. The rates of recurrence are variable in literature, between 10% and 67%. OBJECTIVE To define the recurrence rate of basal cell carcinoma with positive margins after surgery. Secondarily, identify morphological aspects that can suggest a more frequent tumoral recurrence. METHODS This was a retrospective and observational study made by analysis of medical records of 487 patients between January 2003 and December 2009 in Hospital de Clínicas da Universidade Federal do Paraná (HC-UFPR). From 402 basal cell carcinomas surgically treated, 41 fulfilled inclusion criteria and were evaluated for five years or more. Recurrence rate of these tumors was analyzed in all patients and clinical characteristics such as sex, age, tumor size, tumor site, ulceration, and histological type were evaluated in order to find if they were related to more common tumoral recurrence. RESULTS The rate of positive margins after surgery was 12.18%. There were five cases of tumoral recurrence in the observation group and three cases in the re-excision group. Tumor size, site, histological type, ulceration and type of positive margin did not differ statistically between groups. It was not possible to consider if these factors were important in recurrence rates. STUDY LIMITATIONS Ideally, a prospective study with a larger sample would be more accurate. CONCLUSION The treatment of choice in basal cell carcinoma with positive margins must be individualized to reduce recurrence rates. PMID:28225958

    Full Text Available Introduction: Many histopathological parameters in oral tongue squamous cell carcinoma (OTSCC have been identified as predictive factors. Certain tumor-related factors increase the risk of nodal metastasis, and many pathological factors affect survival. Objective: The objective of this study is to identify that tumor-related histopathological prognostic factors that can predict recurrence and potentially influence the decision for adjuvant radiotherapy in early stage OTSCC. Materials and Methods: A total of 51 patients who underwent surgery for early stage OTSCC (stage I, II from 2007 to 2013 were selected. Demographic and clinical details were retrieved. Histopathological reports were reviewed for the following parameters-Margin status (close <5 mm, positive - Invasive squamous cell carcinoma [SCC], carcinoma in situ, marked dysplasia, microscopic depth of invasion, skeletal muscle infiltration (SMI, tumor differentiation, perineural invasion, lymphovascular invasion. Overall survival and recurrence-free survival (RFS were calculated using the Kaplan-Meier method. Predictors of recurrence were identified using Univariate analysis. Results: Median follow-up was 22 months (range, 5-89 months, the overall survival and RFS were 88% and 81% respectively. The recurrence rate was 19.5% during this time period. The only significant predictor of recurrence in pathologically early stage OTSCC was SMI (P = 0.003 on univariate analysis. Eighty-seven percentage of the recurrences in our study occurred within the 1 st year, with a disease specific mortality rate of 12.5%. Conclusion: In early stage OTSCC, Failure occurred predominantly in patients who had SMI.

    Fanconi’s Anaemia is a rare autosomal recessive disease for which the incidence of head and neck cancer can be increased 700-fold1. We report a case of a 31-year old Caucasian male with FA who initially presented in July 2007 with oral squamous cell carcinoma for which he received radical surgery and radiotherapy. He was disease-free until August 2015 when he presented with an extremely aggressive recurrence.

  10. Surgical Management of Local Recurrences of Renal Cell Carcinoma

    Full Text Available Surgical resection either in the form of radical nephrectomy or in the form of partial nephrectomy represents the mainstay options in the treatment of kidney cancer. In most instances, resecting the tumor bearing kidney or the tumor itself provides durable cancer specific survival rates. However, recurrences may rarely develop in the renal fossa or remnant kidney. Despite its rarity, locally recurrent RCC is a challenging condition in terms of the possible management options and relatively poor prognosis. If technically feasible, wide surgical excision and ensuring negative surgical margins are the most effective treatment options. Repeat surgeries (completion nephrectomy, excision of locally recurrent tumor, or repeat partial nephrectomy may often be complicated, and perioperative morbidity is a major concern. Open approach has been extensively applied in this context and 5-year cancer specific survival rates have been reported to be around 50%. The roles of minimally invasive surgical options (laparoscopic and robotic approach and nonsurgical alternatives (cryoablation, radiofrequency ablation have yet to be described. In selected patients, surgical resection may have to be complemented with (neoadjuvant radiotherapy or medical treatment.

    The authors report two cases of recurrent transitional cell carcinoma at the anastomotic site of the ileal conduit and ureter after total cystectomy. In one patient, a recurrent tumor was also found in the distal ureter which had not been removed during previous nephrectomy. At follow up, the patients presented with gross hematuria or hydronephrosis, and the presence of mass lesions was demostarted by intravenous urography, antegrade pyelography, and/or loopography. Transitional cell carcinoma was diagnosed by surgery and pathologic examination.

  12. Recurrent dermatomyositis manifesting as a sign of recurrent transitional cell carcinoma of urinary bladder: Long-term survival

    2014-01-01

    Full Text Available The association between urological malignancies and paraneoplastic syndromes has been well documented. We report a case of recurrent dermatomyositis manifesting as a sign of metastatic recurrence of non-muscle-invasive transitional cell carcinoma of the bladder, a relationship which has only been referred to in a few reports. The case highlights a few important clinical challenges; firstly, the importance of thorough investigation for underlying malignancy in patients with dermatomyositis, as successful treatment of such malignancy can lead to resolution of paraneoplastic symptoms, and secondly, a high index of suspicion of recurrence in cases where paraneoplastic manifestations recur. Metastatic pulmonary recurrence without local evidence of disease at a follow-up of 4 years makes this case unique. Moreover, in the light of our experience and reported literature, a framework is suggested to approach such a diagnostic dilemma in the future. Description of the case will guide clinicians in the future, in case they encounter such an unusual clinical scenario. This could also serve as a hypothesis-generating source for designing future research as well.

    Forkhead box protein P3 (FOXP3) expression in tumor infiltrating CD4+T cells is generally associated with an intrinsic capacity to suppress tumor immunity. Based on this notion, different studies have evaluated the prognostic value of this maker in cancer but contradictory results have been found. Indeed, even within the same cancer population, the presence of CD4+FOXP3+T cells has been associated,with either a poor or a good prognosis, or no correlation has beenfound. Here, we demonstrate,in patients with oral squamous cell carcinoma (OSCC), that what really represents a prognostic parameter is not the overall expression of FOXP3 but its intracellular localization.While overallFOXP3 expression in tumor infiltrating CD4+T cells does not correlate with tumor recurrence, its intracellular localization within the CD4 cells does: nuclear FOXP3 (nFOXP3) is associated with tumor recurrence within 3 years, while cytoplasmicFOXP3 (cFOXP3) is associated with a lower likelihood of recurrence. Thus, we propose elevated levels of the cFOXP3/nFOXP3 ratio within tumor infiltrating CD4+ T cells as a predictor of OSCC recurrence. PMID:23977174

    The prognosis of locally advanced or recurrent squamous cell carcinoma (SCC) of the penis after conventional treatment is dismal. This study aimed to evaluate the therapeutic effects of intraarterial chemotherapy with gemcitabine and cisplatin on local y advanced or recurrent SCC of the penis. Between April 1999 and May 2011, we treated 5 patients with locally advanced penile SCC and 7 patients with recurrent disease with intraarterial chemotherapy. The response rate and toxicity data were analyzed, and survival rates were calculated. After 2 to 6 cycles of intraarterial chemotherapy with gemcitabine and cisplatin, 1 patients with locoregional y advanced disease achieved a complete response, and 4 achieved partial response. Of the 7 patients with recurrent disease, 2 achieved complete response, 3 achieved partial response, 3 had stable disease, and 1 developed progressive disease. An objective tumor response was therefore achieved in 10 of the 12 patients. The median overal survival for the patients was 24 months (range, 10-50 months). Three out of 10 patients who responded were long-term survivors after intraarterial chemotherapy. Intraarterial chemotherapy with gemcitabine and cisplatin may be effective and potential y curative in locoregional y advanced or recurrent penile SCC. The contribution of this therapy in the primary management of advanced or recurrent penile SCC should be prospectively investigated.

    Squamous cell carcinomas of the anus are rare neoplasias that account for about 3% of large bowel tumours. Infections with human papillomaviruses are frequently detected in these cancers, suggesting that pathogenic pathways in anal carcinomas and in carcinomas of the uterine cervix are similar. Little is known regarding recurrent chromosomal aberrations in this subgroup of squamous cell carcinomas. We have applied comparative genomic hybridization to identify chromosomal gains and losses in 23 cases of anal carcinomas. A non-random copy number increase of chromosomes 17 and 19, and chromosome arm 3q was observed. Consistent losses were mapped to chromosome arms 4p, 11q, 13q and 18q. A majority of the tumours were aneuploid, and most of them showed increased proliferative activity as determined by staining for Ki-67 antigen. p53 expression was low or undetectable, and expression of p21/WAF-1 was increased in most tumours. Sixteen cancers were satisfactorily tested for the presence of HPV by consensus L1-primer polymerase chain reaction; nine were HPV positive, of which eight were positive for HPV 16.

    Both long-term administration of immunosuppressive agents and chronic inflammatory conditions, such as autoimmune disease, could be risk factors for the development of cutaneous squamous cell carcinoma (cSCC). In this report, we present a case of recurrent multiple cSCC on the scalp in a patient with juvenile dermatomyositis who had been administered cyclosporine and Predonine since she was a 1-year-old infant. Interestingly, immunohistochemical staining revealed IL-17-producing cells adjacent to IL-17R-expressing atypical keratinocytes. Our present case suggested that IL-17/IL-17R signaling might contribute to the carcinogenesis of cSCC. PMID:28203172

    AIM: To detect the effects of plasma DNA methylation of Wnt antagonists/inhibitors on recurrence of esophageal squamous cell carcinoma (ESCC).METHODS: We used methylation-specific polymerase chain reaction to detect hypermethylation of the promoter of four Wnt antagonists/inhibitors (SFRP-1, WIF-1, DKK-3 and RUNX3) using DNA from the plasma of ESCC patients (n = 81) and analyzed the association between promoter hypermethylation of Wnt pathway modulator genes and the two-year recurrence of ESCC.RESULTS: Hypermethylation of SFRP-1, DKK-3 and RUNX-3 was significantly associated with an increased risk of ESCC recurrence (P = 0.001, 0.003 and 0.001 for SFRP-1, DKK-3 and RUNX3, respectively). Patients carrying two to three methylated genes had a significantly elevated risk of recurrence compared with those not carrying methylated genes (odds ratio = 15.69, 95% confidential interval: 2.97-83). The area under the receiver operating characteristic curve (AUC) was 77.1 for ESCC recurrence prediction (sensitivity = 66.67 and specificity = 83.3). When combining methylated genes and the clinical stage, the AUC was 83.69, with a sensitivity of 76.19 and a specificity of 83.3.CONCLUSION: The status of promoter hypermethylation of Wnt antagonists/inhibitors in plasma may serve as a non-invasive prognostic biomarker for ESCC.

    Full Text Available Basal cell carcinoma (BCC is the most common cancer among humans, and the standard treatment is surgery. Other modalities are reserved as a second line of treatment. Topical chemotherapy may be used in primary BCC. Systemic chemotherapy has no role in the primary treatment of BCC, although it may be efficacious in metastatic cases. We report the case of a patient with persistent recurrent BCC following multiple surgeries and radiotherapy, who achieved a dramatic response with a cisplatinand 5-flourouracil chemotherapy regimen.

    Full Text Available The odontogenic keratocysts (OKC usually represent a particular entity that has been of interest primarily due to biological aggressiveness and to its frequent recurrence. Nevoid basal cell carcinoma syndrome (NBCCS, also known as Gorlin syndrome is a hereditary condition characterized by a wide-range of developmental abnormalities and a predisposition to neoplasms. There are several possible reasons why OKC recur so frequently and require meticulous surgical planning and execution. This article has attempted to show that there is a lack of published evidence regarding the cause of frequent recurrent of OKC that presented in NBCCS. However, the findings of the study revealed differences in opinion regarding the treatment modalities, which necessitates further long term clinical studies that could precisely document certain reliable guidelines in this point of view.

    Full Text Available Introduction. Orbital myiasis is the infestation of the orbital tissues by fly larvae or maggots. Compromise of periorbital tissues by malignant disease, surgery, ischemia, or infection may predispose the patient to orbital myiasis. Case Report. A 73-year-old male patient with neglected recurrent basal cell carcinoma of the eyelid invasive into the orbit presented with complaints of intense itching and crawling sensation with maggots wriggling and falling from the wound of left orbit. The patient improved following manual removal of the maggots along with oral Ivermectin treatment. Recurrence of the basal cell carcinoma was confirmed by punch biopsy from the wound and extended exenteration of the orbit followed by reconstructive surgery was done. Conclusion. Orbital myiasis is a rare and preventable ocular morbidity that can complicate the malignancies resulting in widespread tissue destruction. The broad spectrum antiparasitic agent, Ivermectin, can be used as noninvasive means to treat orbital myiasis. In massive orbital myiasis and those associated with malignancies, exenteration of the orbit must be seriously considered.

    Purpose: To present the proportion of patients with periocular basal cell carcinoma (BCC) who underwent orbital exenteration and to evaluate the significance of the risk factors. Design: Retrospective, comparative, interventional case series. Methods: Data of all patients with BCC between 2008 and 2014 were reviewed for patient demographics, previous treatment options, tumor localization, and histopathologic subtype. Results: In group of 256 patients, orbital exenteration underwent 7 patients (2.7%). For 2 patients (5.1%), orbital exenteration was the first procedure performed. In the exenterated group, the most common tumor site was the medial cantus and lower eyelid, whereas in the overall group, it was the lower eyelid (P = 0.011). The proportion of patients initially treated with histopathologic result of infiltration of 1 margin was significantly higher in patients undergoing exenteration (P = 0.282). During the 7-year period observership, the authors have seen 13 recurrences (5.08%). In patients with recurrent BCC after surgery, the authors applied adjuvant high dose rate 192Ir brachytherapy. Neoadjuvant therapy with Vismodegib was effective in patient with biorbital infiltration after 1 side exenteration. Conclusions: Orbital invasion may be clinically silent. Recurrence rate of BCC in our group 5% corresponds to date in the literature. The exenteration for BCC may be significantly higher when the lesion involves a medial canthal location and lower eyelid and initial surgery does not include margin-controlled excision.

    Renal cell carcinomas (RCCs) have a strong tendency to metastasize, and the most common sites are the lungs, bones and liver. Late recurrence is another feature of the RCC, with lesions appearing ≥10 years after surgical treatment. However, fibrosis has rarely been associated with the disease. The present study reports a case of recurrent RCC that manifested as a fibrotic mass within the thorax. A 48-year-old man presented with dyspnea that had persisted for 3 days. The patient had undergone a right radical nephrectomy for stage II clear cell carcinoma of the kidney 6 years previously. The patient was a current smoker, with a smoking history of 20 pack-years. Chest radiography showed pleural effusion in the right thorax with an egg-sized mass shadow within the right upper lung (RUL) field. Computed tomography (CT) showed a main mass, 7 cm in diameter, within the RUL, with heterogeneous enhancement and multiple nodules of various sizes in the lungs, suggestive of primary lung cancer or metastatic RCC. A CT-guided percutaneous needle aspiration biopsy was obtained from the main mass, but histology revealed dense fibrous tissue without any malignant cells. Positron emission tomography-CT demonstrated an irregular hypermetabolic RUL mass, with a standardized uptake value (SUV) of 5.0, along the right pleura, and small pulmonary nodules (SUV, 2.0). Ultrasound-guided biopsy was attempted for a smaller hypermetabolic pleural nodule and the result was clear cell adenocarcinoma, consistent with the previous renal histology. The present study describes the case, along with a review of the relevant literature. PMID:27313703

    Primary squamous cell carcinoma of the thyroid gland (PSCCT) is a rare malignancy that presents with advanced disease and poor prognosis. It is difficult to diagnose PSCCT in its early stage because of its rarity and lack of typical imaging findings. We experienced an elderly woman with PSCCT confirmed by surgery. Although preoperative fine-needle aspiration revealed no malignancy, surgical resection was performed because the ultrasonogram showed diffuse microcalcifications, which suggested malignancy, and clinically, the mass grew rapidly to compress the trachea. Local tumor recurrence was noted at 3 months after surgery. Surgical resection or repeat biopsy should be considered if a cytologically benign thyroid mass shows imaging or clinical features of malignancy.

    Objective: To study recurrence factors and set up a model to evaluate the prognosis of patients with bladder cancer.Methods: An analysis on recurrence-related factors was made by Cox's proportional hazards model analysis and logistic multiple linear regression model analysis in 212 patients with transitional cell carcinoma treated surgically from 1995~2001.These factors included clinical and pathologic figures. Results: The most important factor is metastasis to the regional lymph nodes, the Hazards ratio is 6.6 (P=0.0004), followed by multiple tumors (Hr=2.255, P<0.0001), tumor in trigone and bladder neck (Hr=2.053, P<0.0001), stage (Hr=2.057, P<0.0001), grade (Hr=1.569, P=0.0081), intravesical chemotherapeutic instillations (Hr-0.559, P=0.0011) and hematuria (Hr=0.762, P=0.0076). A predicting equation was established, and the predicting values were calculated according to the individual features of patients. The predicting and actual values were compared, and the sensitivity, specificity and overall concordance were 83.5%, 67.6% and 80.1% respectively. Conclusion:The evaluation of prognosis could be made quite accurately based on these factors.

    Purpose: Methods to estimate the likely origin of recurrences after radiation therapy for head and neck squamous cell carcinoma are compared. Methods and materials: A total of 25 patients meeting the following inclusion criteria were randomly selected: curatively intended intensity-modulated radiotherapy planned on a positron emission tomography-computed tomography (PET/CT) scan during the period 2005-2009; squamous cell carcinoma in the oral cavity, pharynx or larynx; complete clinical response followed by locoregional recurrence; and a CT scan at recurrence before any salvage therapy. Exclusion criteria were previous cancer in the area, surgery prior to radiotherapy, or a synchronous cancer. Three methods of estimating focal points of recurrence origin and two volume overlap methods assigning the recurrences to the most central target volumes encompassing at least 50% or 95% of the recurrence volumes were tested. Treatment planning and recurrence scans were rigid and deformable co-registered in order to transfer focal points to the treatment planning scan. Double determinations of all volumes, points, and co-registrations were made. Results: The volume overlap methods assigned the recurrences to significantly more peripheral target volumes than focal methods (p < 0.0001 for all comparisons of 95% overlap vs. focal methods, p < 0.028 for all comparisons of 50% overlap vs. focal methods). Repeated registrations of the same point had higher reproducibility with deformable registration than with rigid registration (median distance 0.31 vs. 0.35 cm, p = 0.015). No significant differences were observed among the focal methods. Conclusion: Significant differences between methods were found which may affect strategies to improve radiotherapy based on pattern of failure analyses. (orig.)

    Full Text Available Abstract Background Liver transplantation is the most effective therapy for cirrhosis-associated hepatocellular carcinoma (HCC but its utility is limited by post-transplant tumor recurrence. Use of the Milan, size-based criteria, has reduced recurrence rate to less than 10% but many patients remain ineligible. Reduction of tumor size with local therapies has been used to “downstage” patients to allow them to qualify for transplantation, but the optimal criteria to predict tumor recurrence in these latter patients has not been established. The existence of a progenitor cell population, sometimes called cancer stem cells (CSCs, has been proposed to be one mechanism accounting for the chemotherapy resistance and recurrence of hepatocellular carcinoma. The aim of this study was to determine if transcatheter arterial chemoemolization (TACE treated tumors have increased CSC marker expression and whether these markers could be used to predict tumor recurrence. Methods Formalin fixed specimens were obtained from 39 HCC liver explants (23 with no treatment and 16 after TACE. Immunohistochemical staining was performed for EpCAM, CD44, CD90, and CD133. Staining for each marker was scored 0–3 by evaluating the number and intensity of positive tumor cells in 5 hpf of tumor in each specimen. Results TACE treated tumors displayed greater necrosis and fibrosis than non-TACE treated samples but there were no differences in morphology between the viable tumor cells of both groups. In TACE treated specimens, the staining of both EpCAM and CD133 was greater than in non-TACE specimens but CD44 and CD90 were the same. In the TACE group, the presence of high EpCAM staining was associated with tumor recurrence. Four of ten EpCAM high patients recurred while 0 of 6 EpCAM low patients recurred (P = 0.040. None of the other markers predicted recurrence. Conclusion High pre-transplant EpCAM staining predicted HCC recurrence. This suggests that the abundance of

    Objective To describe management and oncologic outcomes for patients who develop locoregional recurrence (LRR) or distant metastasis (DM) following transoral robotic surgery for human papilloma virus (HPV)-positive oropharyngeal squamous cell carcinoma (OPSCC). Study Design Case series with chart review. Setting Tertiary care referral center. Subjects and Methods A total of 286 patients with HPV-positive OPSCC who underwent transoral robotic surgery-based treatment from May 2007 to May 2015. Results Of 286 patients (12.2%), 35 met inclusion criteria. Of these, 19 experienced an LRR and 16 developed a DM; 2 patients with LRR subsequently developed DM. In those patients with an LRR, 79% had T1/T2 tumors, and 47% had N0/N1 nodal disease, compared with 75% and 6% in the DM group, respectively. The median time to LRR or DM was 0.6 years (interquartile range [IQR], 0.4-1.0) and 1.8 years (IQR, 1.0-2.1), respectively. Salvage treatment with intent to cure was attempted in 23 patients (16 LRR, 7 DM). The median time from LRR or DM to last follow-up for the 18 patients who were still alive after salvage was 1.9 years (IQR, 0.4-3.8; range, 7 days-6.2 years). Estimated cancer-specific survival rates at 3 years following intent-to-cure treatment were 63% (95% CI, 39-100; number still at risk, 5) in the LRR group and 100% (95% CI, 100-100; number still at risk, 2) in the DM group. Conclusion Overall, LRR and DM for HPV-positive OPSCC following transoral robotic surgery-based therapy are infrequent. In our subset of patients who underwent intent-to-cure treatment, cancer-specific survival rates were favorable. Therefore, aggressive salvage treatment for LRR and DM for HPV-positive OPSCC should be recommended for appropriate candidates.

    The data and regulatory considerations leading to the U.S. Food and Drug Administration (FDA) January 30, 2012 approval of Erivedge (vismodegib) capsules for the treatment of patients with recurrent, locally advanced, or metastatic basal cell carcinoma (BCC) are described. The FDA's approval decision was based primarily on the results observed in a single-arm, parallel cohort, international trial of vismodegib, administered orally at 150 mg daily until disease progression, in patients with pathologically confirmed, recurrent, locally advanced basal cell carcinoma (laBCC) or metastatic basal cell carcinoma (mBCC). An independent review committee confirmed an overall response rate (ORR) of 30.3% [95% confidence interval (CI): 15.6-48.2] in 33 patients with mBCC and an ORR of 42.9% (95% CI: 30.5-56.0) in 63 patients with laBCC; median response durations were 7.6 months and 7.6 months for patients with mBCC and laBCC, respectively. The most common adverse reactions were muscle spasms, alopecia, dysgeusia, weight loss, fatigue, nausea, diarrhea, decreased appetite, constipation, cough, arthralgias, vomiting, headache, ageusia, insomnia, and upper respiratory tract infection. Animal toxicology studies confirmed that vismodegib is a potent teratogenic agent. Approval was based on durable objective tumor responses supported by knowledge of the pathologic role of Hedgehog signaling in BCC and acceptable toxicity in a population without effective alternative therapies.

    Full Text Available Primary Squamous Cell Carcinoma in the kidney is a rare malignant neoplasm associated with nephrolithiasis, typically monobacterial pyonephrosis and rarely Xanthogranulomatous pyelonephritis. It is an aggressive disease with a poor prognosis mostly due to lack of presenting clinical features like a palpable mass, gross haematuria and pain. We report a case presenting with renal calculus and pyonephrosis managed initially with percutaneous nephrostomy followed by nephrectomy due to complete loss of renal function. Histopathological evaluation revealed poorly differentiated squamous cell carcinoma which is managed by chemotherapy, although initially beneficial, patients later develop disseminated metastatic disease which holds a poor prognosis.

    Full Text Available Objective: Loss of heterozygosity (LOH studies were undertaken to investigate the consistently deleted loci/? tumor suppressor gene loci (TSG on 3p in conventional renal cell carcinoma (cRCC. Materials and Methods: LOH studies were performed by polymerase chain reaction (PCR using 15 micro satellite markers mapped in region 3p12-p26 on 40 paired cRCC tumors and normal kidney at Stages I-IV. Simultaneously, fluorescent in-situ hybridization (FISH studies were performed to investigate the allelic deletion of fragile histidine triad (FHIT. Results: Our studies revealed three affected regions; 3p12.2-p14.1, 3p14.2-p21.1, and 3p24.2-p26.1 with differential frequencies in Group I (Stage I and II and Group II (Stage III and IV. Incidence for D3S1234 (FHIT locus and D3S2454 (3p13 was 75% and 83% in Group I and II, respectively. Comparative allelotyping in epithelial malignancies like lung, bladder, and breast tumors revealed LOH (frequency 14−20% only in breast tumors for D3S2406, D3S1766 (distal to FHIT, and D3S1560 (distal to VHL, Von-Hippal Lindau. FISH using FHIT gene probe revealed deletions in cRCC (88%, breast (30%, and lung tumors (10% with no deletions in bladder tumors and leukemias, signifying the importance of FHIT in the pathogenesis of tumors of epithelial origin. Conclusion: Our findings suggested FHIT deletion as an early and VHL deletion as an early and/or late event in cRCC. Additionally, studies also disclosed the recurrent deletions of flanking loci to FHIT and VHL in cRCC. The dilemma of interstitial or continuous deletion on 3p needs to be resolved by implementation of latest sensitive molecular techniques that would further help to narrow down search for TSG loci specific to cRCC, other than VHL and FHIT.

    The purpose of our study was 1) to evaluate the diagnostic performance of 18F-fluorodeoxyglucose (FDG) positron emission tomography (PET)/computed tomography (CT), 2) to assess the impact of FDG PET/CT on treatment decision-making, and 3) to estimate the prognostic value of FDG PET/CT in the restaging process among patients with renal cell carcinoma (RCC). From the FDG PET/CT databases of San Raffaele Hospital in Milan, Italy, and the Veneto Institute of Oncology in Padua, Italy, we selected 104 patients with a certain diagnosis of RCC after surgery, and for whom at least 24 months of post-surgical FDG PET/CT, clinical, and instrumental follow-up data was available. The sensitivity and specificity of FDG PET/CT were assessed by histology and/or other imaging as standard of reference. Progression-free survival (PFS) and overall survival (OS) were computed using the Kaplan-Meier method. Univariate and multivariate Cox proportional hazards models were used to identify predictors of outcome. FDG PET/CT resulted in a positive diagnosis in 58 patients and a negative diagnosis in 46 patients. Sensitivity and specificity were 74 % and 80 %, respectively. FDG PET/CT findings influenced therapeutic management in 45/104 cases (43 %). After a median follow-up period of 37 months (± standard deviation 12.9), 51 (49 %) patients had recurrence of disease, and 26 (25 %) had died. In analysis of OS, positive versus negative FDG PET/CT was associated with worse cumulative survival rates over a 5-year period (19 % vs. 69 %, respectively; p <0.05). Similarly, a positive FDG PET/CT correlated with a lower 3-year PFS rate. In addition, univariate and multivariate analysis revealed that a positive scan, alone or in combination with disease stage III-IV or nuclear grading 3-4, was associated with high risk of progression (multivariate analysis = hazard ratios [HRs] of 4.01, 3.7, and 2.8, respectively; all p < 0.05). FDG PET/CT is a valuable tool both in treatment decision-making and for

    Full Text Available Abstract Background The occurrence of skeletal muscle metastases is a very rare event. Only two cases of late skeletal muscle recurrence from cervical cancer have been documented until now. Case presentation A 38-year old patient, submitted to radical hysterectomy and pelvic lymphadenectomy for a squamous FIGO stage IB1 cervical carcinoma, presented after 76 months with a palpable, and painless swelling on the left hemithorax. MRI showed a nodule located in the context of the intercostal muscles. Pathology revealed the presence of metastasis of squamous cell carcinoma of similar morphology as the primary. On the basis of FDG-PET findings, which excluded other sites of disease, surgical excision of the lesion was performed. The patient was triaged to chemotherapy plus external radiotherapy. Conclusion A case of skeletal muscle recurrence from cervical cancer after a very long interval from primary diagnosis is reported. Muscular pain or weakness, or just a palpable mass in a patient with a history of cancer has always to raise the suspicion of muscle metastasis.

    Objective: To investigate the status of hematogenous spreading of hepatocellular carcinoma (HCC) before or after surgical treatment or transcatheter arterial chemoembolization (TACE) and to elucidate the significance of peripheral blood Alphafetoprotein (AFP) mRNA expression in predicting recurrence or metastasis of HCC. Methods: Peripheral venous bloods were collected from 60 patients with HCC,20 of whom had received TACE before blood samples were collected, and from 30 subjects as control (10 cases with benign liver disorders, 20 healthy donors). AFP cDNA was amplified from 5 ml whole blood by nested reverse transcription polymerase chain reaction (RTPCR). Results: Of the 60 patients with HCC, 32 cases (53.3%) had positive AFP mRNA in their peripheral blood. In 33 patients with intra-and/or extrahepatic metastasis, 27 (81.1%) were positive for AFP mRNA. In patients who didn't yet have metastasis when samples were collected, 11 (29.7%) gave positive AFP mRNA, 6of whom developed tumor recurrence or metastasis after the samples were collected. The presence of AFP mRNA correlated with the stage of HCC and the presence of intrahepatic and/or extrahepatic metastasis, but did not correlate with tumor size and serum AFP level. There was no significant difference in AFP mRNA expression before and after surgical treatment or TACE.Conclusion: Detection of AFP mRNA by PCR provides a sensitive and specific assay of hematogenous dissemination of HCC. TACE can not prevent metastasis of HCC. Systemic chemotherapy or immunotherapy is needed to prevent occult or overt metastasis.

    Penile squamous cell carcinoma (SCC) is considered a loco-regional disease with a fairly predictable pattern of progression. Widespread dissemination occurs in at least one-third of the patients. Local recurrence (defined as the presence of tumor after a primary treatment affecting any remainder tissue, including skin, erectile corpora, or urethra) present in up to 30% of the patients increases the risk of regional inguinal and pelvic lymph nodes metastases. The aim of this study was to identify adverse pathologic prognostic factors in patients with recurrent tumors. Clinicopathologic features of 81 surgically treated patients (25 with recurrent and 56 with nonrecurrent SCC) were evaluated; 56 patients (19 with recurrent and 37 with nonrecurrent tumors) additionally received groin dissections. Follow-up (2 to 372 mo, mean of 71 mo) was obtained in all patients. Comparison of recurrent tumors at the time of the primary diagnosis and of recurrence showed that histologic subtype and grade were identical in 76% of the cases and converted to a higher grade tumor in 24% of the cases, especially, in patients treated with local excisions and circumcisions. Most of the recurrences (67%) seemed at or before 12 months. Comparison of recurrent and nonrecurrent tumors showed that high grade tumors (basaloid and sarcomatoid) tended to be significantly associated with recurrent tumors, whereas low grade variants (papillary, warty and verrucous) were more frequent in the nonrecurrent group; recurrent tumors invaded into deeper anatomic levels than nonrecurrent tumors. The incidence of inguinal lymph node metastasis was higher in recurrent tumors (79% vs. 49%, P=0.0272). Cancer-specific survival was of 46% versus 76% at 3 years of follow-up in recurrent and nonrecurrent tumors, respectively. Patients with recurrent tumors had a median survival of 2.9 years; no major changes in survival were noted after 3 years of follow-up. Mortality was higher in the recurrent group (56% vs. 29

However, controversies still exist about the postoperative prophylactic radiation target volume. This study was designed to analyze the patterns of recurrence and to provide a reference for determination of the postoperative radiotherapy target volume for patients with midthoracic ESCC.Patients and methods: A total of 338 patients with recurrent or metastatic midthoracic ESCC after radical surgery were retrospectively examined. The patterns of recurrence including locoregional and distant metastasis were analyzed for these patients.Results: The rates of lymph node (LN metastasis were 28.4% supraclavicular, 77.2% upper mediastinal, 32.0% middle mediastinal, 50.0% lower mediastinal, and 19.5% abdominal LNs. In subgroup analyses, the rate of abdominal LN metastasis was significantly higher in patients with histological node-positive than that in patients with histological node-negative (P=0.033. Further analysis in patients with histological node-positive demonstrated that patients with three or more positive nodes are more prone to abdominal LN metastasis, compared with patients with one or two positive nodes (χ2=4.367, P=0.037. The length of tumor and histological differentiation were also the high-risk factors for abdominal LN metastasis.Conclusion: For midthoracic ESCC with histological node-negative, or one or two positive nodes, the supraclavicular and

    Merkel cell carcinoma (MCC) is an aggressive neuroendocrine skin cancer with poorly characterized genetics. We performed high resolution comparative genomic hybridization on 25 MCC specimens using a high-density oligonucleotide microarray. Tumors frequently carried extra copies of chromosomes 1, 3q, 5p, and 6 and lost chromosomes 3p, 4, 5q, 7, 10, and 13. MCC tumors with less genomic aberration were associated with improved survival (P=0.04). Tumors from 13 of 22 MCC patients had detectable Merkel cell polyomavirus DNA, and these tumors had fewer genomic deletions. Three regions of genomic alteration were of particular interest: a deletion of 5q12-21 occurred in 26% of tumors, a deletion of 13q14-21 was recurrent in 26% of tumors and contains the well-characterized tumor suppressor RB1, and a previously unreported focal amplification at 1p34 was present in 39% of tumors and centers on L-Myc (MYCL1). L-Myc is related to the c-Myc proto-oncogene, has transforming activity, and is amplified in the closely related small cell lung cancer. Normal skin showed no L-Myc expression, whereas 4/4 MCC specimens tested expressed L-Myc RNA in relative proportion to the DNA copy number gain. These findings suggest several genes that may contribute to MCC pathogenesis, most notably L-Myc.

  6. Joint Effect of Urinary Total Arsenic Level and VEGF-A Genetic Polymorphisms on the Recurrence of Renal Cell Carcinoma.

    Directory of Open Access Journals (Sweden)

    Shu-Mei Yang

    Full Text Available The results of our previous study suggested that high urinary total arsenic levels were associated with an increased risk of renal cell carcinoma (RCC. Germline genetic polymorphisms might also affect cancer risk and clinical outcomes. Vascular endothelial growth factor (VEGF plays an important role in vasculogenesis and angiogenesis, but the combined effect of these factors on RCC remains unclear. In this study, we explored the association between the VEGF-A -2578C>A, -1498T>C, -1154G>A, -634G>C, and +936C>T gene polymorphisms and RCC. We also evaluated the combined effects of the VEGF-A haplotypes and urinary total arsenic levels on the prognosis of RCC. This case-control study was conducted with 191 RCC patients who were diagnosed with renal tumors on the basis of image-guided biopsy or surgical resections. An additional 376 age- and gender-matched controls were recruited. Concentrations of urinary arsenic species were determined by a high performance liquid chromatography-linked hydride generator and atomic absorption spectrometry. Genotyping was investigated using fluorescent-based TaqMan allelic discrimination. We observed no significant associations between VEGF-A haplotypes and RCC risk. However, the VEGF-A ACGG haplotype from VEGF-A -2578, -1498, -1154, and -634 was significantly associated with an increased recurrence of RCC (OR = 3.34, 95% CI = 1.03-10.91. Urinary total arsenic level was significantly associated with the risk of RCC in a dose-response manner, but it was not related to the recurrence of RCC. The combination of high urinary total arsenic level and VEGF-A risk haplotypes affected the OR of RCC recurrence in a dose-response manner. This is the first study to show that joint effect of high urinary total arsenic and VEGF-A risk haplotypes may influence the risk of RCC recurrence in humans who live in an area without obvious arsenic exposure.

    2013-07-01

    The incidence of Well-differentiated Thyroid Carcinoma (WDTC) has been increasing over the past several decades. Consequently, so has the incidence of recurrence, which ranges from 15% to 30%. Factors leading to increased risk of recurrence are well described. However, the impact of local and regional recurrence is not well understood, but distant recurrence dramatically reduces 10-year survival to 50%. Recurrent WDTC has several established options for treatment; Observation, Radioactive Iodine (RAI), Surgery and External Beam Radiotherapy (EBRT). Novel treatments such as radiofrequency ablation (RFA) and percutaneous ultrasound-guided ethanol injection (PUEI) are beginning to gain popularity and have promising early results. A review of the current literature, outcome measurements and a strategy for revision surgery within the central neck compartment are discussed within this manuscript.

Complete surgical resection offers the best chance of long-term survival. However, despite complete resection, ACC is associated with high recurrence rates. This review will discuss the management of recurrent ACC in adults following complete surgical resection. Management should take place in a specialist center and treatment decisions must consider the individual tumor biology of each case of recurrence. Given the fact that ACC commonly recurs, management to prevent recurrence should be considered from initial diagnosis with the use of adjuvant mitotane. Close follow up with clinical examination and imaging is important for early detection of recurrent disease. Locoregional recurrence may be isolated, and repeat surgical resection should be considered along with mitotane. The use of radiotherapy in ACC remains controversial. Systemic recurrence most often involves liver, pulmonary, and bone metastasis and is usually managed with mitotane, with or without combination chemotherapy. There is a limited role for surgical resection in systemic recurrence in selected patients. In all patients with recurrent disease, control of excessive hormone production is an important part of management. Despite intensive management of recurrent ACC, treatment failure is common and the use of clinical trials and novel treatment is an important part of management.

    AIM: To investigate the effects of autologous tumor vaccine on recurrence of hepatocellular carcinoma (HCC).METHODS: Sixty patients with HCC who had undergone curative resection, were randomly divided into HCC vaccine group and control group. Three vaccinations at 2-wk intervals were performed after curative hepatic resection. Delayedtype- hypersensitivity (DTH) test was performed before and after vaccination. Primary endpoints were the time of recurrence.RESULTS: Four patients in control group and 6 patients in HCC vaccine group were withdrawn from the study. The vaccine containing human autologous HCC fragments showed no essential adverse effect in a phase Ⅱ clinical trial and 17 of 24 patients developed a DTH response against the fragments. Three of 17 DTH-positive response patients and 5 of 7 DTH- negative response patients had recurrences after curative resection. After the operation,1-, 2- and 3-year recurrence rates of HCC vaccine groupwere 16.7%, 29.2% and 33.3%, respectively. But, 1-, 2- and3-year recurrence rates of the control group were 30.8%,53.8% and 61.5%, respectively. The time before the first recurrence in the vaccinated patients was significantly longer than that in the control patients (P<0.05).CONCLUSION: Autologous tumor vaccine is of promise in decreasing recurrence of human HCC.

    Locoregional recurrence remains the main pattern of failure after primary combined modality treatment of squamous cell carcinoma of the head and neck (SCCHN). We compared the efficacy and toxicity of either cisplatin or cetuximab in combination with re-irradiation (ReRT) for recurrent unresectable SCCHN. Various clinicopathological factors were investigated to establish a prognostic score. Between 2007 and 2014, 66 patients with recurrent SCCHN originating in a previously irradiated area received cetuximab (n = 33) or cisplatin-based chemotherapy (n = 33) concomitant with ReRT. Toxicity was evaluated weekly and at every follow-up visit. Physical examination, endoscopy, CT or MRI scans were used to evaluate response and disease control. With a mean follow-up of 18.3 months, the 1-year overall survival (OS) rates for Re-RT with cetuximab and cisplatin-based chemotherapy were 44.4 and 45.5 % (p = 0.352), respectively. At 1 year, local control rates (LCR) were 46.4 and 54.2 % (p = 0.625), freedom from metastases (FFM) rates 73.6 and 81 % (p = 0.842), respectively. Haematological toxicity ≥ grade 3 occurred more often in the cisplatin group (p < 0.001), pain ≥ grade 3 was increased in the cetuximab group (p = 0.034). A physiological haemoglobin level and a longer interval between primary RT and ReRT, proved to be significant prognostic factors for OS (multivariate: p = 0.003, p = 0.002, respectively). Site of the recurrence and gross target volume (GTV) did not show a significant impact on OS in multivariate analysis (p = 0.160, p = 0.167, respectively). A prognostic-score (1-4 points) based on these four variables identified significantly different subgroups: 1-year OS for 0/1/2/3/4 prognostic points: 10, 38, 76, 80 and 100 %, respectively (p < 0.001). Both cetuximab- and cisplatin-based ReRT of SCCHN recurrences are feasible and effective treatment options with comparable results in terms of tumour control and survival. Acute adverse events may differ slightly

    Purpose: There are limited therapeutic options for patients with recurrent head and neck cancer after radiation therapy failure. To assess the use of tumor necrosis factor–related apoptosis-inducing ligand (TRAIL) as a salvage chemotherapeutic agent for recurrent cancer after radiation failure, we investigated the effect of clinically relevant cumulative irradiation on TRAIL-induced apoptosis. Methods and Materials: Using a previously established HN3 cell line from a laryngeal carcinoma patient, we generated a chronically irradiated HN3R isogenic cell line. Viability and apoptosis in HN3 and HN3R cells treated with TRAIL were analyzed with MTS and PI/annexin V-FITC assays. Western blotting and flow cytometry were used to determine the underlying mechanism of TRAIL resistance. DR4 expression was semiquantitatively scored in a tissue microarray with 107 laryngeal cancer specimens. Methylation-specific polymerase chain reaction and bisulfite sequencing for DR4 were performed for genomic DNA isolated from each cell line. Results: HN3R cells were more resistant than HN3 cells to TRAIL-induced apoptosis because of significantly reduced levels of the DR4 receptor. The DR4 staining score in 37 salvage surgical specimens after radiation failure was lower in 70 surgical specimens without radiation treatment (3.03 ± 2.75 vs 5.46 ± 3.30, respectively; P<.001). HN3R cells had a methylated DR4 CpG island that was partially demethylated by the DNA demethylating agent 5-aza-2′-deoxycytidine. Conclusion: Epigenetic silencing of the TRAIL receptor by hypermethylation of a DR4 CpG island might be an underlying mechanism for TRAIL resistance in recurrent laryngeal carcinoma treated with radiation.

    Isolated skeletal metastasis in endometrial carcinoma at recurrence is very rare. We report a 52-year-old woman diagnosed to have FIGO Stage 1b, Grade 1 endometrioid adenocarcinoma, presenting with isolated distal humerus metastasis, 2 years after surgery and adjuvant radiotherapy for primary disease. Imaging, bone scintigraphy, and cytology confirmed the diagnosis of poorly differentiated metastatic adenocarcinoma. She was treated with local radiotherapy followed by six cycles of paclitaxel and carboplatin chemotherapy along with zoledronic acid, monthly. She is symptom-free after the treatment and at a first follow-up visit after 3 months. PMID:27688615

    Merkel cell carcinoma is a rare aggressive neuroendocrine carcinoma of the skin predominantly affecting elderly Caucasians. It has a high rate of local recurrence and regional lymph node metastases. It is associated with a poor prognosis. Complete spontaneous regression of Merkel cell carcinoma has been reported but is a poorly understood phenomenon. Here we present a case of complete spontaneous regression of metastatic Merkel cell carcinoma demonstrating a markedly different pattern of events from those previously published.

    Full Text Available Membranous glomerulonephritis can occur as a rare paraneoplastic complication of human cancers. In this case report, we describe a patient who presented acutely with symptoms of the nephrotic syndrome including heavy proteinuria and anasarca. He was subsequently diagnosed with membranous glomerulonephritis, and soon afterwards was found to have stage IIIB non-small cell lung cancer. Following chemoradiation therapy, both the patient’s cancer and membranous glomerulonephritis dramatically improved. However, approximately 14 months following his initial presentation, the patient was found to have a recurrence of his nephrotic-range proteinuria which corresponded temporally with recurrence of his cancer. We present details of the case and a review of the relevant scientific literature.

    Hepatocellular carcinoma (HCC) is the leading cause ofdeaths in patients with hepatitis B or C, and its incidencehas increased considerably over the past decade and is stillon the rise. Liver transplantation (LT) provides the bestchance of cure for patients with HCC and liver cirrhosis.With the implementation of the MELD exception systemfor patients with HCC waitlisted for LT, the number ofrecipients of LT is increasing, so is the number of patientswho have recurrence of HCC after LT. Treatments forintrahepatic recurrence after transplantation and afterother kinds of surgery are more or less the same, butlong-term cure of posttransplant recurrence is rarelyseen as it is a "systemic" disease. Nonetheless, surgicalresection has been shown to be effective in prolongingpatient survival despite the technical difficulty in resectinggraft livers. Besides surgical resection, different kindsof treatment are also in use, including transarterialchemoembolization, radiofrequency ablation, highintensityfocused ultrasound ablation, and stereotacticbody radiation therapy. Targeted therapy and modulationof immunosuppressants are also adopted to treat thedeadly disease.

    We performed a prospective phase II trial to investigate the safety and efficacy of radiotherapy combined with capecitabine in patients suffering from a recurrence of a squamous cell carcinoma of the head and neck (SCCHN) within a previously irradiated field. A total of 31 evaluable patients with recurrent SCCHN received re-irradiation with a total dose of 50 Gy (25 fractions over 5 weeks) up to a maximum of 60 Gy combined with 900 mg/m{sup 2}/day capecitabine given on the days of radiotherapy. The median time to relapse after the first course of radiotherapy was 15 months. The overall response rate in our study was 68% including 6 patients with a complete response. The median overall survival was 8.4 months. Grade 3 or 4 mucositis occurred in 4 patients and 1 patient, respectively. No grade 4 hematological toxicities were observed; 1 patient had grade 3 anemia. The cumulative median lifetime dose was 116 Gy. Capecitabine combined with re-irradiation is a well-tolerated treatment in patients with recurrent SCCHN. In light of its good tolerability, it appears to be a potential option for patients with a reduced performance status and may also serve as a basis for novel treatment concepts, such as in combination with targeted therapies.

    PURPOSE We retrospectively analyzed the risk of recurrence and conditional Disease-Free Survival (cDFS) in 63 patients with complete remission during treatment with tirosin kinase inhibitor (TKI), alone or with local treatment in metastatic renal cell carcinoma. RESULTS 37% patients achieve CR with TKI alone, while 63% with additional loco-regional treatments. 49% patients recurred after CR, with a median Disease free survival of 28.2 months. Patients treated with multimodal approaches present lower rate of recurrence (40% vs 61%) and longer Disease free survival compared to patient treated with TKI alone (16.5 vs 41.9 months, p=0.039).Furthermore the rate of recurrence was higher in patients with brain (88%), pancreatic (71%) and bone metastasis (50%). Patients who continued TKI therapy after complete response had a longer disease free survival than patients who stopped therapy, although the difference was not significant (42.1 vs 25.1 months, p=0.254). 2y-cDFS was better in patients treated with multimodal treatment and who continued TKIs than the other patient arms. CONCLUSIONS The prognostic value of CR depends on the site where was obtained and how was obtained (with or without locoregional treatment). Cessation of TKI should be carefully considered in complete responder patients. PMID:27027342

    Full Text Available Abstract Background Aggressive non-melanoma skin cancer (deeply infiltrating, recurrent, and morphea form lesions are therapeutically challenging because they require considerable tissue loss and may demand radical disfiguring surgery. Interferons (IFN may provide a non-surgical approach to the management of these tumors. The aim of this work was to evaluate the effect of a formulation containing IFNs-α and -γ in synergistic proportions on patients with recurrent, advanced basal cell (BCC or squamous cell skin carcinomas (SCSC. Methods Patients with extensive, recurrent, resistant to other procedures BCC or SCSC received the IFN formulation peri- and intralesionally, three times per week for 3 weeks. They had been previously treated with surgery and/or radiotherapy or chemotherapy. Thirteen weeks after the end of treatment, the original lesion sites were examined for histological evidence of remaining tumor. Results Sixteen elder (median 70 years-old patients were included. They beared 12 BCC and 4 SCSC ranging from 1.5 to 12.5 cm in the longest dimension. At the end of treatment 47% CR (complete tumor elimination, 40% PR (>30% tumor reduction, and 13% stable disease were obtained. None of the patients relapsed during the treatment period. The median duration of the response was 38 months. Only one patient with complete response had relapsed until today. Principal adverse reactions were influenza-like symptoms well known to occur with interferon therapy, which were well tolerated. Conclusion The peri- and intralesional combination of IFNs-α and -γ was safe and showed effect for the treatment of advanced, recurrent and resistant to previous treatments of BCC and SCSC in elder patients. This is the first report of such treatment in patients with advance non-melanoma skin cancer. The encouraging result justifies further confirmatory trials.

    Interleukin-4 (IL-4) and IL-13 are anti-inflammatory and immunoregulatory cytokines that can influence cancer-directed immunosurveillance. However, they are not evaluated as biomarkers for ccRCC outcomes. The aim of this study was to investigate the prognostic value of tumor-derived IL-4 and IL-13 in patients with localized ccRCC after surgery. Our study comprised 194 consecutive patients with localized ccRCC undergoing nephrectomy in a single center. Clinical characteristics, recurrence-free survival (RFS) and overall survival (OS) were recorded. We assessed IL-4 and IL-13 expression as continuous variables and dichotomized as low versus high by immunohistochemistry. For associations with RFS and OS, we used the Kaplan-Meier method and Cox regression models. Concordance index was calculated for predictive accuracy. We found that high expression levels of IL-4 and IL-13 were associated with increased recurrence (P IL-13 expression (IL-4/IL-13 signature) was an independent prognostic factor for RFS and OS (P = 0.009 and P = 0.016, respectively). When applied to UISS score, IL-4/IL-13 signature improved the predictive accuracy. Notably, this improvement in prediction was mainly observed in patients with low-risk disease. To conclude, IL-4/IL-13 signature is an independent predictor of outcomes in patients with localized ccRCC, and the prognostic value is more prominent among patients with low-risk disease. Evaluation of IL-4 and IL-13 expression provides the opportunity to optimize postsurgical management and develop novel targeted therapies for ccRCC patients.

Besides morphological sequences, we performed single-shot echo-planar DWI at b = 1000 s/mm2 and b = 2000 s/mm2, and corresponding ADC maps were generated (ADC1000 and ADC2000, resp.. By considering contrast-enhanced T1-weighted images as references, ROIs were drawn in order to evaluate mean ADC1000, ADC2000, and ADCratio. The mean ADC1000 and ADC2000 in recurrent tumors were significantly lower than those in posttreatment changes (P=0.001 and P=0.016, resp.. Moreover, the mean ADCratio between the two groups showed a statistically significant difference (P=0.002. Sensitivity, specificity, and accuracy of ADCratio were 82.0%, 100%, and 90%, respectively, by considering an optimal cutoff value of 65.5%. ADCratio is a promising value to differentiate between recurrent tumors and posttreatment changes in HNSCC and may be more useful than ADC1000 and ADC2000.

    At the time of diagnosis, 60% of patients with head and neck squamous cell carcinoma (HNSCC) present tumors in an advanced stage (III-IV) of disease and 80% will relapse within the first two years post-treatment, due to their frequent radio(chemo)resistance. To identify new molecular targets and companion biomarkers, we have investigated the miRNome of 75 stage III-IV oropharynx tumors without relapse (R) or with loco-regional relapse (non-responder, NR) within two years post-treatment. Interestingly, miR-422a was significantly downregulated in NR tumors, in agreement with the increase in cell proliferation and adhesion induced by miR-422a inhibition in vitro. Furthermore, we identified CD73/NT5E oncogene as target of miR-422a. Indeed, modulation of the endogenous level of miR-422a inversely influences the expression and the enzymatic activity of CD73. Moreover, knocking down CD73 mimics the effects of miR-422a upregulation. Importantly, in tumors, miR-422a and CD73 expression levels are inversely correlated, and both are predictive of relapse free survival - especially considering loco(regional) recurrence - in vitro two independent cohorts of advanced oropharynx or HNSCC (N=255) tumors. In all, we reported, for the first time, that MiR-422a and its target CD73 are involved in early loco(regional) recurrence of HNSCC tumors and are new targets for personalized medicine.

    Purpose/Objective(s): This study aimed to analyze outcomes in a multi-institutional cohort of patients with advanced or recurrent renal cell carcinoma (RCC) who were treated with intraoperative radiation therapy (IORT). Methods and Materials: Between 1985 and 2010, 98 patients received IORT for advanced or locally recurrent RCC at 9 institutions. The median follow-up time for surviving patients was 3.5 years. Overall survival (OS), disease-specific survival (DSS), and disease-free survival (DFS) were estimated with the Kaplan-Meier method. Chained imputation accounted for missing data, and multivariate Cox hazards regression tested significance. Results: IORT was delivered during nephrectomy for advanced disease (28%) or during resection of locally recurrent RCC in the renal fossa (72%). Sixty-nine percent of the patients were male, and the median age was 58 years. At the time of primary resection, the T stages were as follows: 17% T1, 12% T2, 55% T3, and 16% T4. Eighty-seven percent of the patients had a visibly complete resection of tumor. Preoperative or postoperative external beam radiation therapy was administered to 27% and 35% of patients, respectively. The 5-year OS was 37% for advanced disease and 55% for locally recurrent disease. The respective 5-year DSS was 41% and 60%. The respective 5-year DFS was 39% and 52%. Initial nodal involvement (hazard ratio [HR] 2.9-3.6, P<.01), presence of sarcomatoid features (HR 3.7-6.9, P<.05), and higher IORT dose (HR 1.3, P<.001) were statistically significantly associated with decreased survival. Adjuvant systemic therapy was associated with decreased DSS (HR 2.4, P=.03). For locally recurrent tumors, positive margin status (HR 2.6, P=.01) was associated with decreased OS. Conclusions: We report the largest known cohort of patients with RCC managed by IORT and have identified several factors associated with survival. The outcomes for patients receiving IORT in the setting of local recurrence compare favorably to

    Patients with superficial bladder cancers remain clinically indolent after treatment with even a modicum of urologic intervention. However, with more invasive disease, the majority of patients experience recurrence. The conventional route of metastasis and recurrence in primary urothelial cell carcinoma is through lymphatic system, with regional lymph nodes, lungs, liver, brain, and bone being the most common sites. Isolated intraluminal colonic recurrence in the absence of local invasion is extremely rare. We report a unique case of urothelial cell carcinoma presenting with an isolated colonic mass, which unexpectedly, on immunohistostaining, proved to be primarily of urothelial rather than colonic origin.

    Full Text Available Photodynamic therapy (PDT with aminolevulinic acid (ALA to treat nodular basal cell carcinoma (BCC has been shown to be beneficial. The success rate of ALA-PDT in the treatment of nodular BCC is dependent on optimal penetration of the photosensitizing agent and subsequent PpIX production. To enhance topical delivery of drugs intradermally, a needleless jet injection (NLJI, which employs a high-speed jet to puncture the skin without the side effects of needles, was used in one patient with recurrent BCC of the nose. Photoactivation was then performed using red light emitting diode [CW @ λ 630 nm, irradiance 50 mW/cm2, total fluence 51 J/cm2] for 17 minutes. Excellent cosmesis was obtained. Aside from mild crusting present for six days, no other adverse signs were noted. Clinically, there was no recurrent lesion up two years postintervention. Additional studies in larger samples of subjects are needed to further evaluate this promising technique.

    The objective of our study was to define a neural network for predicting recurrence and progression-free probability in patients affected by recurrent pTaG3 urothelial bladder cancer to use in everyday clinical practice. Among all patients who had undergone transurethral resection for bladder tumors, 143 were finally selected and enrolled. Four follow-ups for recurrence, progression or survival were performed at 6, 9, 12 and 108 months. The data were analyzed by using the commercially available software program NeuralWorks Predict. These data were compared with univariate and multivariate analysis results. The use of Artificial Neural Networks (ANN) in recurrent pTaG3 patients showed a sensitivity of 81.67% and specificity of 95.87% in predicting recurrence-free status after transurethral resection of bladder tumor at 12 months follow-up. Statistical and ANN analyses allowed selection of the number of lesions (multiple, HR=3.31, p=0.008) and the previous recurrence rate (>or=2/year, HR=3.14, p=0.003) as the most influential variables affecting the output decision in predicting the natural history of recurrent pTaG3 urothelial bladder cancer. ANN applications also included selection of the previous adjuvant therapy. We demonstrated the feasibility and reliability of ANN applications in everyday clinical practice, reporting a good recurrence predicting performance. The study identified a single subgroup of pTaG3 patients with multiple lesions, >or=2/year recurrence rate and without any response to previous Bacille Calmette-Guérin adjuvant therapy, that seem to be at high risk of recurrence.

    2012-01-01

    Full Text Available We report a case of a Caucasian male with a history of renal cell carcinoma metastatic (mRCC to the lungs refractory despite aggressive treatment with several lines of targeted therapy. He was started on axitinib palliative targeted therapy with a good clinical and radiological response; however one month after treatment initiation he presented to the emergency department with severe dyspnea and hypoxemia. Physical exam and chest X-ray revealed left-sided tension pneumothorax which required emergent thoracostomy with subsequent improvement; however it recurred requiring video assisted thoracoscopy. A left-sided 4 × 3 cm cavitated necrotic lesion was found at the level of the main pulmonary artery. Repair with pericardial fat flap was performed. Surgical biopsies from this lesion revealed mRCC with extensive necrosis. Imaging studies before and after axitinib use showed an initial 4 × 3 cm mass seen in the same location of this large cavitated necrotic tumor. Pneumothorax has not been described as a potential major complication from the use of axitinib. Complete or near-complete responses of mRCC to axitinib targeted therapy may lead to this potential life-threatening complication, particularly if the metastatic lesions are located near to pleural structures. We also review pertinent clinical trial data on axitinib.

    Hepatocellular carcinoma (HCC) cells often invade the portal venous system and subsequently develop into portal vein tumour thrombosis (PVTT). Long noncoding RNAs (lncRNAs) have been associated with HCC, but a comprehensive analysis of their specific association with HCC metastasis has not been conducted. Here, by analysing 60 clinical samples' RNA-seq data from 20 HCC patients, we have identified and characterized 8,603 candidate lncRNAs. The expression patterns of 917 recurrently deregulated lncRNAs are correlated with clinical data in a TCGA cohort and published liver cancer data. Matched array data from the 60 samples show that copy number variations (CNVs) and alterations in DNA methylation contribute to the observed recurrent deregulation of 235 lncRNAs. Many recurrently deregulated lncRNAs are enriched in co-expressed clusters of genes related to cell adhesion, immune response and metabolic processes. Candidate lncRNAs related to metastasis, such as HAND2-AS1, were further validated using RNAi-based loss-of-function assays. Thus, we provide a valuable resource of functional lncRNAs and biomarkers associated with HCC tumorigenesis and metastasis. PMID:28194035

    Basal cell carcinoma (BCC) accounts for nearly 25% of all cancers in the human body and for almost 75% of skin malignancies; approximately 85% of basal cell carcinomas develop in the head and neck region. Limited demographic, clinical and histological predictors for second primary and/or recurrent BCC have been identified to date. Our objective was to identify predictors of recurrence and second primary tumour development of BCC in the head and neck region. We included 1062 patients with a histologically confirmed diagnosis of BCC. Multivariate and Cox regression analysis were used to access demographic, clinical and histological predictors. Study follow up included 4,302 patient-years, each patient was followed-up for an average 4.0 +/- 1.8 years (range 1-12). Overall recurrence rate was 4%. High-risk histology type was associated with an increased risk for recurrence (odds ratio (OR) = 3.47, 95%CI: 1.07-11.25). We calculated a 4-fold increased risk for recurrence with positive excision margins (OR = 4.31, 95%CI: 1.82-10.22), a 21% increased risk for recurrence (OR = 1.21, 95%CI: 1.06-1.37) and a 25% increased risk for second primary BCC development (OR = 1.25, 95%CI: 1.17-1.34) per year of follow-up. The median time free of second primary tumour was 7 years, while the median time free of recurrence was 12 years. The strongest predictors for recurrence are positive excision margins and high-risk histology type, indicating the need for additional patient care in such cases.

    Purpose: To investigate the role of galectin-1 in patients with cervical cancer after definitive radiation therapy. Methods and Materials: We reviewed 154 patients with International Federation of Gynecology and Obstetrics stage I-II squamous cell carcinoma. Patients underwent curative-intent radiation therapy. Paraffin-embedded tissues were analyzed using immunohistochemistry staining for galectin-1. The rates of cancer-specific survival (CSS), local recurrence (LR), and distant metastasis were compared among patient tissue samples with no, weak, and strong galectin-1 expression. The Kaplan-Meier method and the Cox proportional hazard model with hazard ratios and 95% confidence intervals (CIs) were used for univariate and multivariate analyses, respectively. Results: The areas under the curve for the intracellular expression scores of galectin-1 for both LR and CSS were significantly higher than those for stromal expression. There were no significant differences in the demographic data, such as stage and serum tumor markers, between patients with and without intracellular expression of galectin-1 in cancer tissue samples. Using multivariate analyses, the hazard ratios of LR and CSS were 2.60 (95% CI 1.50-4.52) (P=.001) and 1.94 (95% CI 1.18-3.19) (P=.010), respectively. Conclusion: Galectin-1 is an independent prognostic factor associated with LR and CSS in stage I-II cervical cancer patients undergoing definitive radiation therapy. Further studies targeting galectin-1 may improve the local control of cervical cancer.

    2016-01-28

    Differentiated thyroid carcinoma (DTC) comprises over 90% of thyroid tumors and includes papillary and follicular carcinomas. Patients with DTC have an excellent prognosis, with a 10-year survival rate of over 90%. However, the risk of recurrent tumor ranges between 5% and 30% within 10 years of the initial diagnosis. Cervical lymph node disease accounts for the majority of recurrences and in most cases is detected during follow-up by ultrasound or elevated levels of serum thyroglobulin. Recurrent disease is accompanied by increased morbidity. The mainstay of treatment of nodal recurrence is surgical management. We provide an overview of the literature addressing surgical management of recurrent or persistent lymph node disease in patients with DTC.

    To investigate low-tube-voltage 80-kVp computed tomography (CT) of head and neck primary and recurrent squamous cell carcinoma (SCC) regarding objective and subjective image quality. We retrospectively evaluated 65 patients (47 male, 18 female; mean age: 62.1 years) who underwent head and neck dual-energy CT (DECT) due to biopsy-proven primary (n = 50) or recurrent (n = 15) SCC. Eighty peak kilovoltage and standard blended 120-kVp images were compared. Attenuation and noise of malignancy and various soft tissue structures were measured. Tumor signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) were calculated. Subjective image quality was rated by three reviewers using 5-point grading scales regarding overall image quality, lesion delineation, image sharpness, and image noise. Radiation dose was assessed as CT dose index volume (CTDI{sub vol}). Interobserver agreement was calculated using intraclass correlation coefficient (ICC). Mean tumor attenuation (153.8 Hounsfield unit (HU) vs. 97.1 HU), SNR (10.7 vs. 8.3), CNR (8.1 vs. 4.8), and subjective tumor delineation (score, 4.46 vs. 4.13) were significantly increased (all P < 0.001) with 80-kVp acquisition compared to standard blended 120-kVp images. Noise of all measured structures was increased in 80-kVp acquisition (P < 0.001). Overall interobserver agreement was good (ICC, 0.86; 95 % confidence intervals: 0.82-0.89). CTDI{sub vol} was reduced by 48.7 % with 80-kVp acquisition compared to standard DECT (4.85 ± 0.51 vs. 9.94 ± 0.81 mGy cm, P < 0.001). Head and neck CT with low-tube-voltage 80-kVp acquisition provides increased tumor delineation, SNR, and CNR for CT imaging of primary and recurrent SCC compared to standard 120-kVp acquisition with an accompanying significant reduction of radiation exposure.

    Il cancro del rene rappresenta la 13a forma di tumore a livello mondiale e risulta incrementata, dal punto di vista epidemiologico, di circa il 2% annuo nelle ultime due decadi. Studi recenti hanno mostrato un numero complessivo di 65,150 nuovi casi di cancro renale diagnosticato nei paesi occidentali e circa 13.680 morti. Il carcinoma a cellule renali rappresenta approssimativamente il 90% di tutte le forme di cancro renale e presenta un tasso di mortalità di circa 4 soggetti ogni 100000 abitanti per anno. Il carcinoma a cellule renali ha, spesso, un particolare corteo sintomatologico caratterizzato da dolore addominale, masse addominali ed ematuria. Caratteristico è il fatto che circa il 25-30% dei pazienti, all’atto della diagnosi, presentano già metastasti a distanza; un ulteriore 30-50%, inoltre, svilupperanno metastasi nel corso della malattia, anche dopo molti anni dall’operazione chirurgica di nefrectomia radicale. Il Cancro del Rene a Cellule Chiare metastatizza in genere per via linfatica, ematogena, transperitoneale o per invasione diretta, ed i siti di metastasi più comuni sono il polmone ed i linfonodi, seguiti dalle ossa e dal fegato. Tra tutte le possibili localizzazioni ai segmenti addominali, il duodeno rappresenta la sede meno colpita: quando coinvolta, viene, in genere, invasa la regione periampollare ed il bulbo del duodeno. Tali localizzazioni danno segno di sè, spesso tardivamente, con sanguinamenti (ematemesi) o ostruzioni del tratto gastrointestinale superiore (vomito). Il nostro caso clinico descrive un carcinoma a cellule renali che si presentava, dopo soli 5 mesi dalla nefrectomia radicale destra, con sanguinamento del tratto gastrointestinale superiore e metastasi a carico del duodeno, e che è stato trattato chirurgicamente con duodenocefalopancreasectomia. L’intervento chirurgico, noto per essere altamente demolitivo ed associato ad elevata morbilità, applicato a recidiva precoce di cancro, ha garantito un ottimo risultato

    Recurrence after hepatocellular carcinoma (HCC) isfrequent. Currently, there are no recommendations ontherapeutic strategy after recurrence of HCC. Whereasthe 5 year-recurrence rate after resection of HCC is 100%,this drops to 15% after primary liver transplantation.Repeat hepatectomy and salvage liver transplantation(SLT) could be performed in selected patients to treatrecurrent HCC and enable prolonged overall survivalafter treatment of recurrence. Other therapies such aslocal ablation, chemoembolization or sorafenib couldbe proposed to those patients unable to benefit fromresection or SLT. A clear definition of the place of SLT and"prophylactic" liver transplantation is required. Indeed,identifying risks factors for recurrence at time of primaryliver resection of HCC may help to avoid recurrencebeyond Milan criteria and non-resectable situations. Inthis review, we summarize the recent data available inthe literature on the feasibility and outcomes of repeathepatectomy and SLT as treatment for recurrent HCC.

    Full Text Available A 77-year-old male patient presented with an ulcerated exophytic tumor (T2, N0, M0 with three macroscopically visible satellite metastases in the right temporo-occipital region. Mohs surgery could not control the disease due to lymphangiosis carcinomatosa and perineural infiltration, and recurrence of satellite skin metastases. Re-staging demonstrated a T2, N1, M0 profile (stage III, AJCC. Chemotherapy was limited by the patient’s co-morbidities. Therefore, we used targeted therapy with monoclonal anti-epidermal growth factor receptor antibody cetuximab in combination with volumetric modulated arc- radiotherapy (VMAT. Cetuximab was well tolerated except for the loading dose when the patient developed fever chills. To verify the correct application of VMAT, it was applied to a 3-dimensional measuring phantom prior to the patient’s first treatment session. To minimize these tolerances, patient set-up was checked and corrected by orthogonal fluoroscopic images recorded daily by the on-board imager used in our Varian accelerator. The average daily beam time was 6 min (6 arcs, 767 monitor units; the total treatment time including patient set-up and set-up correction was less than 20 min. Combined therapy was well tolerated and complete remission was achieved.

    Purpose: To examine the efficacy and toxicity of continuous-course, conformal reirradiation with weekly paclitaxel and carboplatin for the treatment of locally recurrent, nonmetastatic squamous cell carcinoma of the head and neck (SCCHN) in a previously irradiated field. Methods and Materials: Patients treated with continuous course-reirradiation with concurrent carboplatin and paclitaxel at the Medical College of Wisconsin and the Clement J. Zablocki VA from 2001 through 2009 were retrospectively reviewed. Patients included in the analysis had prior radiation at the site of recurrence of at least 45 Gy. The analysis included patients who received either intensity-modulated radiotherapy (RT) or three-dimensional conformal RT techniques. All patients received weekly concurrent carboplatin (AUC2) and paclitaxel (30-50 mg/m{sup 2}). Results: Thirty-eight patients with nonmetastatic SCCHN met the entry criteria for analysis. The primary sites at initial diagnosis were oropharyngeal or laryngeal in most patients (66%). Median reirradiation dose was 60 Gy (range, 54-70 Gy). Acute toxicity included Grade 2 neutropenia (5%), Grade 3 neutropenia (15%), and Grade 1/2 thrombocytopenia (8%). No deaths occurred from hematologic toxicity. Chemotherapy doses held (50%) was more prevalent than radiation treatment break (8%). Sixty-eight percent of patients required a gastrostomy tube in follow-up. Significant late toxicity was experienced in 6 patients (16%): 1 tracheoesophageal fistula, 1 pharyngocutaneous fistula, 3 with osteoradionecrosis, and 1 patient with a lingual artery bleed. Patients treated with three-dimensional conformal RT had more frequent significant late toxicites than patients treated with intensity-modulated RT (44% and 7% respectively, p < 0.05). The median time to progression was 7 months and progression-free rates at 1, 2, and 5 years was 44%, 34%, and 29% respectively. The median overall survival was 16 months. Overall survival at 1, 3, and 5 years was 54

A total of 55 patients with stage I (n = 42) and recurrent (n = 13) NSCLC underwent hypofractionated PBT and were retrospectively reviewed. A total dose of 50-72 CGE (cobalt gray equivalent) in 5-12 fractions was delivered. The median follow-up duration was 29 months (range 4-95 months). There were 24 deaths (43.6%) during the follow-up period: 11 died of disease progression and 13 from other causes. Kaplan-Meier overall survival rate (OS) at 3 years was 54.9% and the median OS was 48.6 months (range 4-95 months). Local progression was observed in 7 patients and the median time to local progression was 9.3 months (range 5-14 months). Cumulative actuarial local control rate (LCR), lymph node metastasis-free survival, and distant metastasis-free survival rates at 3 years were 85.4, 78.4, and 76.5%, respectively. Larger tumor diameter was significantly associated with poorer LCR (3-year: 94% for ≤3 cm vs. 65% for >3 cm, p = 0.006) on univariate analysis and also an independent prognostic factor for LCR (HR 6.9, 95% CI = 1.3-37.8, p = 0.026) on multivariate analysis. No grade 3 or 4 treatment-related toxicities developed. One grade 5 treatment-related adverse event occurred in a patient with symptomatic idiopathic pulmonary fibrosis. Ablative dose hypofractionated PBT was safe and promising for stage I and recurrent NSCLC. (orig.)

    Penile carcinomas (PeCa) are relatively rare, but devastating neoplasms, more frequent among people of underprivileged socioeconomic status. There is mounting evidence that immune cells may trigger various mechanisms that enhance tumor growth and metastasis, but no data on the peritumoral inflammation is available for PeCa. The objectives of the present study are to evaluate the immunohistomorphology of tumoral inflammation in PeCa, and to correlate it with clinicopathological parameters, which could contribute to the prognostic evaluation. One hundred and twenty-two patients with the diagnosis of usual-type squamous cell penile carcinoma were included. Paraffin-embedded tissue was submitted to immunohistochemical evaluation of p16 protein, CD3, CD4, CD8, CD20, CD68, CD138, granzyme B, and Fox-P3. The Fisher's exact test was employed for comparison between histological variables and parameters, and the Kaplan-Meier method for the analysis of survival. Improved 5-year overall survival was significantly associated to age ≤60 years, stage I + II, tumor size T1 + T2, lymph node status N0, and absent perineural invasion. In a multivariate analysis age ≥60 years, presence of lymph node metastasis, urethral invasion, and high histologic grade retained a significantly more unfavorable outcome. Improved 5-year failure free survival was associated to stage of the disease I + II, lymph node status N0, absence of perineural, vascular, and urethral invasion, and Fox-P3 expression. In a multivariate analysis, presence of lymph node metastasis, perineural and vascular invasion, and of Fox-P3-positive lymphocytes together with low inflammatory infiltrate retained a significantly more unfavorable outcome. These results support the prognostic value of determining the levels of Fox-P3-positive lymphocytes by immunohistochemistry in PeCa, as this parameter adds value to the traditional clinicopathological features.

    Myoepithelial carcinoma is characterized by nearly exclusive myoepithelial differentiation and evidence of malignancy. It may arise de novo or in preexisting benign tumors including pleomorphic adenoma and benign myoepithelioma. A 39-year-old lady presented with painless progressive swelling on the right cheek and right side of palate. On surgery, there was a mass in right maxillary sinus which was surgically excised and diagnosed on histopathology as pleomorphic adenoma. Subsequently, there were two recurrences. The first recurrence was in the right maxilla after 2 years that was removed surgically and diagnosed as pleomorphic adenoma. One year later, she came with rapidly progressive swelling in bilateral cheeks and face. Intraoperatively, there was a large tumor in both maxillary sinuses with extensive local infiltration. Histologically, it was diagnosed as myoepithelial carcinoma. Carcinoma ex pleomorphic adenoma is usually a high grade malignancy. It occurs most commonly in parotid gland followed by submandibular glands, minor salivary glands and occasionally in sublingual gland. To the best of our knowledge, this is the first case of myoepithelial carcinoma arising in a recurrent pleomorphic adenoma in the maxillary sinus.

    Purpose: Salvage options for unresectable locally recurrent, previously irradiated squamous cell carcinoma of the head and neck (rSCCHN) are limited. Although the addition of reirradiation may improve outcomes compared to chemotherapy alone, significant toxicities limit salvage reirradiation strategies, leading to suboptimal outcomes. We therefore designed a phase 2 protocol to evaluate the efficacy of stereotactic body radiation therapy (SBRT) plus cetuximab for rSCCHN. Methods and Materials: From July 2007 to March 2013, 50 patients >18 years of age with inoperable locoregionally confined rSCCHN within a previously irradiated field receiving ≥60 Gy, with a Zubrod performance status of 0 to 2, and normal hepatic and renal function were enrolled. Patients received concurrent cetuximab (400 mg/m{sup 2} on day −7 and then 250 mg/m{sup 2} on days 0 and +8) plus SBRT (40-44 Gy in 5 fractions on alternating days over 1-2 weeks). Primary endpoints were 1-year locoregional progression-free survival and National Cancer Institute Common Terminology Criteria for Adverse Events version 3.0 graded toxicity. Results: Median follow-up for surviving patients was 18 months (range: 10-70). The 1-year local PFS rate was 60% (95% confidence interval [CI]: 44%-75%), locoregional PFS was 37% (95% CI: 23%-53%), distant PFS was 71% (95% CI: 54%-85%), and PFS was 33% (95% CI: 20%-49%). The median overall survival was 10 months (95% CI: 7-16), with a 1-year overall survival of 40% (95% CI: 26%-54%). At last follow-up, 69% died of disease, 4% died with disease, 15% died without progression, 10% were alive without progression, and 2% were alive with progression. Acute and late grade 3 toxicity was observed in 6% of patients respectively. Conclusions: SBRT with concurrent cetuximab appears to be a safe salvage treatment for rSCCHN of short overall treatment time.

    Recurrences occur in 30 % of lung cancer patients after radical therapy; however, known prognostic factors are not always effective. In this study, we investigated whether the frequency of squamous non-small cell lung cancer (NSCLC) recurrence depends on the presence of reactive lesions in tumor-adjacent bronchial epithelium. Specimens of adjacent lung tissue from 104 patients with squamous NSCLC were used for the determination of basal cell hyperplasia (BCH) and squamous metaplasia (SM) and for the analysis of the expression of Ki-67, p53, Bcl-2, and CD138. We found that recurrence was observed in 36.7 % of patients with BCH combined with SM (BCH + SM+) in the same bronchus, compared with 1.8 % in patients with isolated BCH (BCH + SM-; odds ratio (OR) 31.26, 95 % confidence interval (CI) 3.77-258.60; p = 0.00002). The percentage of Ki-67-positive cells was significantly higher in BCH + SM+ than in BCH + SM- (34.9 vs. 18.3 %; effect size 2.86, 95 % CI 2.23-3.47; p = 0.003). P53 expression was also more significant in BCH + SM+ than in BCH + SM- (14.4 vs. 9.6 %; effect size 1.22, 95 % CI 0.69-1.76; p = 0.0008). In contrast, CD138 expression was lower in BCH + SM+ than in BCH + SM- (21.8 vs. 38.5 %; effect size -6.26, 95 % CI -7.31 to -5.22; p = 0.003). Based on our results, we concluded that the co-presence of reactive bronchial lesions is associated with the development of recurrent squamous NSCLC and may be a negative prognostic indicator. In addition, significant differences in Ki-67, p53, and CD138 expression exist between isolated BCH and BCH combined with SM that probably reflect part of biological differences, which could relate to the mechanism of lung cancer recurrence.

    Although subungual squamous cell carcinoma is rare, it is the most common primary malignant neoplasms in this location. The higher incidence occurs in the fingernails, but involvement of the toenails is also possible. Subungual squamous cell carcinoma often looks like other more common benign lesions, such as fungal infection, onychomycosis, or viral wart. These factors, together with a general lack of awareness of this disease among physicians, often result in delayed diagnosis. Therefore, it is underdiagnosed, with few reports in the literature. The authors present a case of a man with a diagnosis of subungual squamous cell carcinoma in the hallux, without bone involvement, which was submitted to the appropriate surgical treatment.

    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.

    Full Text Available Abstract Background Circulating plasma Epstein Barr Virus DNA (EBV-DNA is a sensitive and specific marker of nasopharyngeal carcinoma (NPC. The mainstay of treatment of metastatic NPC is systemic chemotherapy and resection for solitary metastasis. Despite high response rate to chemotherapy, complete remission is uncommonly seen. Case Presentation We report a case of recurrent metastatic NPC in a 43-year-old man, who achieved complete remission three times with chemotherapy and surgery. Serial plasma EBV-DNA levels were measured during the course of disease. The patient had three episodes of recurrences of NPC manifested as distant metastasis. Both time, rise in the plasma EBV-DNA level preceded detection of recurrences by imaging. Following systemic chemotherapy, he achieved complete remission each time, of which was confirmed by 18-flourodeoxyglucose positron emission tomography and hepatectomy pathology. The plasma EBV-DNA level dropped to zero copy/ml at the time of each remission. Conclusion This case highlights the high chemosensitivity of NPC by illustrating a rare occurrence of complete response of metastatic NPC to chemotherapy. This case also underscores the usefulness of EBV-DNA as a useful tool in monitoring NPC by its ability to detect early recurrence and excellent correlation with treatment response.

    2004-01-01

    Anaplastic (giant cell) thyroid carcinoma (ATC), is one of the most aggressive malignancies in humans with a median survival time after diagnosis of 3-6 months. Death from ATC was earlier seen because of local growth and suffocation. ATC is uncommon, accounting for less than 5 % of all thyroid carcinomas. The diagnosis can be established by means of multiple fine needle aspiration biopsies, which are neither harmful nor troublesome for the patient. The cytological diagnosis of this high-grade malignant tumour is usually not difficult for a well trained cytologist. The intention to treat patients with ATC is cure, although only few of them survive. The majority of the patients are older than 60 years and treatment must be influenced by their high age. We have by using a combined modality regimen succeeded in achieving local control in most patients. Every effort should be made to control the primary tumour and thereby improve the quality of remaining life and it is important for patients, relatives and the personnel to know that cure is not impossible. Different treatment combinations have been used since 30 years including radiotherapy, cytostatic drugs and surgery, when feasible. In our latest combined regimen, 22 patients were treated with hyper fractionated radiotherapy 1.6Gy x 2 to a total target dose of 46 Gy given preoperatively, 20 mg doxorubicin was administered intravenously once weekly and surgery was carried out 2-3 weeks after the radiotherapy. 17 of these 22 patients were operated upon and none of these 17 patients got a local recurrence. In the future we are awaiting the development of new therapeutic approaches to this aggressive type of carcinoma. Inhibitors of angiogenesis might be useful. Combretastatin has displayed cytotoxicity against ATC cell lines and has had a positive effect on ATC in a patient. Sodium iodide symporter (NIS) genetherapy is also being currently considered for dedifferentiated thyroid carcinomas with the ultimate aim of

He reported loss of appetite, intermittent post-prandial nausea, bloating and early satiety. He also complained of dyspepsia and had been treated for reflux during the previous 2 years. He denied vomiting, dysphagia, odynophagia, abdominal pain, melena, hematochezia, or alterations in bowel habits. Additionally, he denied fevers, night sweats, cough, or dyspnea. He quit smoking 25 years ago, and denied alcohol use. His past medical history was significant for basal cell carcinoma treated with local curative therapy and he was without recurrence on surveillance. Pertinent family history included a paternal uncle with lung cancer at the age of 74. Physical examination was unremarkable except for occult heme-positive stools. Laboratory evaluation revealed elevated liver enzymes (ALT-112, AST-81, AlkPhos-364). CT scan of the chest, abdomen and pelvis showed diffuse heterogeneous liver with extensive nodularity, raising the concern for metastases. Serum tumor-markers: PSA, CEA, CA 19-9, and AFP were all within normal limits. Screening colonoscopy was normal, but esophagogastroduodenoscopy revealed a malignant-appearing ulcerative lesion involving the gastro-esophageal junction and gastric cardia. Pathology confirmed an invasive gastric large cell neuroendocrine carcinoma. Ultrasound-guided fine needle aspiration of a hepatic lesion revealed malignant cells with cytologic features consistent with large-cell type carcinoma and positive immunostaining for synaptophysin favoring neuroendocrine differentiation. A PET-CT demonstrated intense diffuse FDG uptake of the liver, suggesting diffuse hepatic parenchymal infiltration by tumor. There were multiple foci of intense osseous FDG uptake with corresponding osteolytic lesions seen on CT scan. The remaining intra-abdominal and intra-thoracic structures were unremarkable.

    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.

    As a result of donor shortage and high postoperative morbidity and mortality after liver transplantation,hepatectomy is the most widely applicable and reliable option for curative treatment of hepatocellular carcinoma(HCC).Because intrahepatic tumor recurrence is frequent after loco-regional therapy,repeated treatments are advocated provided background liver function is maintained.Among treatments including local ablation and transarterial chemoembolization,hepatectomy provides the best long-term outcomes,but studies comparing hepatectomy with other nonsurgical treatments require careful review for selection bias.In patients with initially unresectable HCC,transarterial chemo-or radio-embolization,and/or systemic chemotherapy can down-stage the tumor and conversion to resectable HCC is achieved in approximately 20%of patients.However,complete response is rare,and salvage hepatectomy is essential to help prolong patients’survival.To counter the short recurrence-free survival,excellent overall survival is obtained by combining and repeating different treatments.It is important to recognize hepatectomy as a complement,rather than a contraindication,to other nonsurgical treatments in a mul-tidisciplinary approach for patients with HCC,including recurrent or unresectable tumors.

    BACKGROUND:Liver transplantation is the optimal treat-ment for a selected group of patients with moderate to severe cirrhosis and hepatocellular carcinoma (HCC). Despite the strict selection of candidates, post-transplant recurrence often occurs and markedly reduces the long-term survival of patients with HCC. The present review focuses on the current strategies on preventing the recurrence of HCC after liver transplantation. DATA SOURCES:Relevant articles were identiifed by exten-sive searching of PubMed using the keywords "hepatocellular carcinoma", "recurrence" and "liver transplantation" between January 1996 and January 2014. Additional papers were searched manually from the references in key articles. RESULTS:The current theories of HCC recurrence after liver transplantation are: (i) the growth of pre-transplant occult metastases; (ii) the engraftment of circulating tumor cells re-leased at the time of transplantation. Pre-transplant treatment aims to control local tumor by radiofrequency ablation, tran-sarterial embolization and transarterial chemoembolization. The main objective during the operation is to prevent tumor cell dissemination. Post-transplant treatment includes sys-temic anticancer therapy, antiviral therapy, and most recently, immunotherapy. These strategies concentrate on the control of the tumor when the patients are waiting for transplant, to reduce the release of HCC cells during surgical procedures and to clear the occult HCC cells after transplantation. CONCLUSIONS:Much can be done to prevent HCC recurrence after liver transplantation. In future, effort is likely to be di-rected towards combining multidisciplinary approaches and various treatment modalities.

    Full Text Available Large-cell neuroendocrine carcinomas of the lung are extremely rare. There are difficulties related to the diagnosis and treatment and there are no consensus because of the small number of studies. 65-year-old male patient presented with hemoptysis. Chest X-ray and thoracic computorized tomography scan showed a mass lesion and it could not be diagnosed by bronchoscopic biopsy and lavage. Lobectomy was performed due to the high value of standardized uptake value in positron emission tomography. Large cell neuroendocrine carcinoma was diagnosed with pathological evaluation and immunohistochemical study and after 20-month follow-up there was no recurrence. The diagnosis, treatment, and prognosis of large cell neuroendocrine carcinoma in the light of the literature is presented.

    2010-01-01

    Background: Hepatocellular carcinoma (HCC) is the third most common cause of cancer death worldwide. Approximately 80% of patients with HCC have cirrhosis, making liver transplantation (LT) the ideal treatment modality, as it provides a cure for the underlying liver disease as well as complete neoplastic clearance of tumor. Many criteria have been developed for HCC patient selection for LT, although the use of current criteria does not completely eliminate the risk of recurrence. Approximately 15% to 20% of patients who are within the criteria still develop recurrent disease, leading to an extensive search for surrogate markers of HCC aggressiveness. Methods: A prospectively collected database of all patients undergoing LT at our institution between January 1990 and January 2006 with a diagnosis of HCC was retrospectively analyzed. Patients undergoing LT had neutrophil and lymphocyte counts measured preoperatively on the day before surgery. The neutrophil to lymphocyte ratio (NLR) was calculated by dividing the neutrophil measurement by the lymphocyte measurement. An NLR ≥ 5 was considered elevated. Incidence of elevated NLR was compared in LT patients with and without HCC recurrence. Results: Total of 47 patients who underwent LT for HCC were identified. Patients were followed for mean duration of 6 years (range, 8 months – 15 years). Eight (8) patients had recurrence of HCC during the follow-up period. The mean duration between LT and diagnosis of HCC recurrence was 667 days (range, 306 – 1424 days). Twice the number of patients (16) were randomly selected from the remaining 39 patients who had no recurrence. Only 2/8 patients with recurrence and 3/16 patients without recurrence were found to have an elevated NLR. There was no statistical difference in incidence of elevated NLR between patients with and without recurrence (25% vs. 18.75%; P > .05). Conclusions: The effect of inflammation on carcinogenesis has been widely investigated, with recent increased

  3. Management for Patients with De Novo or Recurrent Tumors in the Residual Kidney after Surgery for Nonfamilial Bilateral Renal Cell Carcinoma

    2009-01-01

    Full Text Available The tumor de novo in the residual kidney after surgery for nonfamilial bilateral renal cell carcinoma (RCC is problematic. We reviewed 5 patients who experienced such a situation. Three patients had had metachronous bilateral RCC, treated with radical nephrectomy in one kidney and nephron-sparing surgery (NSS in the other. Two patients had had synchronous disease; one patient had received radical nephrectomy and NSS, and the other bilateral NSS. The 5 patients had another solid mass/de novo tumor in the residual kidney 16–88 (mean 46.8 months after surgery. For the tumor de novo in earlier years (1992–1999, one patient underwent surgery and hemodialysis, and the other selected a conservative observation. In recent years (2000–2007, one patient was conservatively observed; the remaining 2 received computerized-tomography-guided radiofrequency ablation, and the local tumors were well controlled postoperatively for 20 and 12 months with their renal function unimpaired. Ablative techniques can potentially strike a balance between oncological and nephrological outcomes in patients with sporadic multiple RCC, successful management of which was difficult previously.

    Purpose: To evaluate treatment results, elucidate whether national guidelines were followed, and identify areas demanding further treatment optimization. Methods and Material: Between July 2000 and June 2007, 328 patients were treated with curatively intended chemoradiotherapy (CRT) for nonmetastatic squamous cell carcinoma of the anal region, according to national treatment guidelines based on tumor stage. Results: Complete response after CRT was obtained in 87% of patients, rising to 93% after salvage surgery. Chemotherapy, elective irradiation of the groin and salvage surgery were performed to a lesser extent in elderly patients, mainly because of frailty and comorbidity. Recurrence occurred in 24% of the patients, resulting in a 3- and 5-year recurrence-free survival (RFS) of 79% and 74%, respectively. Locoregional recurrences dominated, most commonly in the primary tumor site. Recurrence was treated with curative intent in 45% of the cases. The 3- and 5-year overall survival were 79% and 66%, and cancer-specific survival (CSS) were 84% and 75%, respectively. The risk of adverse outcome increased significantly with more locally advanced tumors and for male gender in multivariable analyses for RFS and CSS. Conclusions: The treatment results are in accordance with similar cohorts. The primary treatment control rate was high, but there was a significant risk of locoregional recurrence in advanced tumors. The loyalty to national guidelines was broad, although individual adjustments occurred. However, caution to avoid toxicity must not lead to inadequate treatment. Male gender seems to have inferior outcome.

    2012-07-01

    Vismodegib is a novel, small-molecule inhibitor of smoothened, a key component of the hedgehog signaling pathway. Increased hedgehog pathway signaling is critical in the development of hereditary and spontaneous basal cell carcinomas of the skin, and has been implicated in the development of a number of other tumors. In preclinical models, vismodegib demonstrated potent antitumor activity in hedgehog-dependent tumors, particularly basal cell carcinomas. Clinically, phase I and II studies showed dramatic anticancer activity in patients with advanced basal cell carcinomas. In January 2012, vismodegib was approved by the FDA for the treatment of unresectable or metastatic basal cell carcinomas of the skin.

    A 55-year-old man with esophageal carcinoma received endoscopic submucosal dissection (ESD) in en-bloc resection. Histopathological examination revealed an admixture of squamous cell carcinoma (SCC) and endocrine cell carcinoma (ECC) with invasion of the deep submucosa. Immunohistochemically, CD 56 and chromogranin A were positive for ECC. Small-cell, medium-cell, and large-cell type ECC were partly surrounded with SCC and partly formed the duct, presenting various patterns. After ESD, he received chemotherapy including CPT-11 plus Cisplatin. He is alive and in good condition today, 55 months after ESD, with no evidence of recurrence.

  7. Expression of Fatty Acid Synthase Depends on NAC1 and Is Associated with Recurrent Ovarian Serous Carcinomas

    2010-01-01

    Full Text Available Our previous reports demonstrated that NAC1, a BTB/POZ domain-containing nuclear protein, upregulates in recurrent ovarian serous carcinoma and participates in developing drug resistance in cancer cells. The current study applies quantitative proteomics to identify the proteins controlled by NAC1 by comparing the proteomes of SKOV3 cells with and without expression of a dominant negative NAC1 construct, N130. From the proteins that are downregulated by N130 (upregulated by NAC1, we chose to further characterize fatty acid synthase (FASN. Similar to change in protein level, the FASN transcript level in SKOV3 cells was significantly reduced by N130 induction or by NAC1 knockdown. Immunohistochemistry showed that NAC1 and FASN immunointensities in ovarian serous carcinoma tissues had a highly significant correlation (P1 in serous carcinomas was associated with a worse overall survival time (P<.01. Finally, C93, a new FASN inhibitor, induced massive apoptosis in carboplatin/paclitaxel resistant ovarian cancer cells. In conclusion, we show that NAC1 is essential for FASN expression in ovarian serous carcinomas and the expression of FASN significantly correlates with tumor recurrence and disease aggressiveness. The dependence of drug resistant tumor cells on FASN suggests a potential application of FASN-based therapeutics for recurrent ovarian cancer patients.

    A 4-year and 2-month-old male capybara (Hydrochoerus hydrochaeris) was diagnosed with squamous cell carcinoma on the buttocks after chronic recurrent dermatosis. The capybara was euthanized, examined by computed tomography and necropsied; the tumor was examined histologically. Computed tomography showed a dense soft tissue mass with indistinct borders at the buttocks. Histological examination of the tumor revealed islands of invasive squamous epithelial tumor cells with a severe desmoplastic reaction. Based on the pathological findings, the mass was diagnosed as a squamous cell carcinoma. This is the first study to report squamous cell carcinoma in a capybara.

    Full Text Available Cancer has become a first order health problem worldwide, despite the great diagnostic and therapeutic programs achieved during the last years. This is a clinical case of an 81- year-old patient with personal and social history of promiscuous and unprotected sexual behavior that shows a vegetative lesion in his gland and numerous inguinal adenopathies. Biopsy confirms the diagnosis of squamous cell carcinoma infiltrating the penis, which is a relatively rare pathology which is generally diagnosed belatedly. Partial amputation of the penis was considered to be performed, but there was no consent on behalf of his family. The patient’s general condition was getting worse until he died.

    Squamous cell carcinoma (SCC) is a relatively common, malignant neoplasm of dogs and cats that can arise in a variety of locations. The gross appearance of SCC can be variable and nonspecific, so definitive diagnosis requires microscopic examination of the tissue (cytology or histology). Several treatment modalities exist, but surgical excision, if possible, is regarded as the best treatment option. Early diagnosis and treatment of SCC are key because small, early-stage tumors are the most amenable to treatment and carry the best prognosis.

    In epithelial ovarian carcinoma, very late (more than 20 years) recurrence is an unusual event. In patients experiencing such a recurrence, the effectiveness of platinum/taxane chemotherapy has been questioned. A 54-year old woman presented with paraaortic node swelling that appeared 25 years after treatment of stage I epithelial ovarian carcinoma. She underwent a partial resection of the nodes and histologic examination showed high-grade serous carcinoma. She received paclitaxel and carboplatin chemotherapy and a partial response was initially observed on imaging studies; however, serum cancer antigen125 levels increased thereafter. She received radiation therapy to the paraaortic nodal disease with doses of 45 Gy and achieved a complete response. She was disease-free more than eight years after the detection of recurrence. In conclusion, radiation therapy may be an effective treatment option in patients with very late recurrence of epithelial ovarian carcinoma refractory to platinum/taxane chemotherapy.

    Full Text Available Xp11 translocation renal cell carcinoma (TRCC is a rare subtype of renal cell carcinoma characterized by chromosomal translocations involving the TFE3 gene located at the Xp11.2 locus. Initial cases were more common in children, but cases in older adults have begun to accrue and suggest a relatively more aggressive course. We report a case of Xp11 TRCC in a 63-year-old female patient with initial presentation mimicking upper urinary tract urothelial cell carcinoma, with biopsy proving TRCC. She underwent a radical nephrectomy and paracaval lymph node dissection and is followed up with the intent to initiate vascular endothelial growth factor–targeted therapy in case of recurrence.

    2003-01-01

    Objective To discuss treatment options for tonsillar squamous cell carcinoma.Methods A total of 108 patients with biopsy-proven tonsillar squamous cell carcinoma, treated between 1984 and 2000, were reviewed, including 82 men and 26 women, with ages ranging from 19 to 70 years. Treatments consisted of either radiotherapy and surgery reserved as salvage treatment (Salvage Surgery, 83 patients), or planned surgery with preoperative radiation (Planned Surgery, 25 patients). Radiotherapy was delivered primarily in a dosage of 60-70 Gy for Salvage Surgery patients and 40-50 Gy for Planned Surgery patients. Both salvage and planned surgeries were radical, with resection of the lateral oropharyngeal wall, segmental resection of the mandible and neck dissection. The pectoralis major myocutaneous flaps were used to repair surgical defects. Results The percentages of radical surgery used in the Salvage Surgery and Planned Surgery groups were 24.1% (20/83) and 88.0% (22/25), respectively (P=0.000). The local recurrence rates were 28.9% (24/83) and 20.0% (5/25) in the Salvage Surgery and Planned Surgery groups, respectively (P= 0.378). The neck recurrence rates were 9.6% (8/83) and 8.0% (2/25) in the Salvage Surgery and Planned Surgery groups respeatively (P= 0.804). The 5-year survival rates were 59.3% and 55.3% in the Salvage Surgery and Planned Surgery groups, respeatively (P= 0.7056).Conclusions Although the two treatments had a similar survival rate, Salvage Surgery avoided 60% commando operations compared with the Planned Surgery group, which benefits to recovery of oral functions. Primary radiotherapy is recommended as the treatment of choice for tonsillar squamous cell carcinoma. After radical radiotherapy, salvage surgery should be undertaken in the case of tumor remnants or recurrences.

    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

  2. Evaluation of 1p Losses in Primary Carcinomas, Local Recurrences and Peripheral Metastases from Colorectal Cancer Patients

    2000-01-01

    Full Text Available Cytogenetic and molecular genetic analyses of colorectal adenomas and carcinomas have shown that loss of the distal part of chromosome arm 1p is common, particularly in tumors of the left colon. Because the importance of 1p loss in colorectal cancer metastases is unknown, we compared the frequency, exact site and extent of ip deletions in primary carcinomas (n=28, local recurrences (n=19 and metastases (n=33 from 67 colorectal cancer patients using 14 markers in an allelic imbalance study. Loss of 1p was found in 50% of the primary carcinomas, 33% of the local recurrences, and 64% of the metastases, revealing a significant difference between the local recurrences and the metastases (P=.04. The smallest region of 1p deletion overlap (SRO defined separately for each group of lesions had the region between markers Di S2647 and D1 S2644, at 1 p35-36, in common. The genes PLA2G2A (1p35.1-36 and TP73 (1p36.3 were shown to lie outside this consistently lost region, suggesting that neither of them are targets for the 1p loss. In the second part of the study, microdissected primary carcinomas and distant metastases from the same colorectal cancer patients (n=18 were analyzed, and the same 1p genotype was found in the majority of patients (12/18, 67%. The finding that primary carcinoma cells with metastatic ability usually contain 1p deletions, and that some cases lacking 1p alterations in the primary tumor acquire such changes during growth of a metastatic lesion, supports the notion that 1p loss may be important both early and late in colorectal carcinogenesis, with the apparent exception of local recurrences.

    The purpose of this study was to evaluate the activity and safety of OSI-211, the liposomal form of lurtotecan, in patients ineligible for curative surgery or radiotherapy and with metastatic/locoregional recurrent squamous cell carcinoma of the head and neck (SCCHN) and target lesions either within a previously irradiated field ("within") or outside a previously irradiated field ("outside"). OSI-211 was given intravenously over 30 min on days 1 and 8 at 2.4 mg/m2/day, repeated every 21 days (1 cycle). From July 2001 to March 2002, 32 patients from 14 institutions were enrolled in the "within" arm and 18 in the "outside" arm. In the "within" arm, two patients were ineligible because their tumour site was not allowed in the protocol (nasopharynx, skin) and two other patients never started treatment. Of the 46 eligible patients who started treatment, there was one objective response (response rate: 2.2% (95% Confidence Interval (CI): [0-11.5%]). Twelve patients in the "within" arm and 6 in the "outside" arm had stable disease, with a median duration of 18 weeks, 95% CI (12.7-25.7). The median time to progression was 6 weeks (95%CI: [5.9-12.7] weeks). Haematological toxicity was moderate in both arms. The most common haematological toxicity was grade 1-2 anaemia in 79% of patients. Non-haematological toxicity was mild in both arms. The most common grade 3-4 non-haematological toxicity was infection in 8.5% of patients. OSI-211 administered on d1 and d8, every 3 weeks, is well tolerated, but shows only minimal activity in locally advanced/metastatic SCCHN.

    Merkel cell carcinoma (MCC) is a rare, aggressive neuroendocrine carcinoma of the skin. Although it is 40 times less common than malignant melanoma, its mortality is much higher compared to melanoma. From 1986 to 2001 there was rapidly increasing incidence in reported cases of MCC, with a tripling in the rate over this 15-year period. The vast majority of MCC presents on sun-exposed skin. The head and neck area is the most common site of tumor occurrence. We present 70-year old female patient with painless red-colored nodule, size 2 x 2 x 2 cm on the dorsal side of mid left forearm. The surgical excision with negative margins was performed, and pathohistological analysis confirmed Merkel cell carcinoma. Sentinel lymph node biopsy was negative. In conclusion, as MCC is a very aggressive rare skin carcinoma with lethal outcome, it should be mandatory to perform biopsies of any suspected skin lesion.

    determination of tumor recurrence. At the end of 7 weeks following tumor resection, 33% of mice with diclofenac-loaded scaffolds had a recurrent tumor, in comparison to 90%–100% of the mice in the other three groups. At this time point, mice with diclofenac-releasing scaffolds showed 89% survival rate, while the other groups showed survival rates of 10%–25%. Immunohistochemical staining of recurrent tumors revealed a near 10-fold decrease in the proliferation marker Ki-67 in the tumors derived from mice with diclofenac-releasing scaffolds. In summary, the local application of diclofenac in an orthotopic mouse tumor resection model of oral cancer reduced tumor recurrence with significant improvement in survival over a 7-week study period following tumor resection. Local drug release of anti-inflammatory agents should be investigated as a therapeutic option in the prevention of tumor recurrence in oral squamous carcinoma.

    Full Text Available The association of squamous cell carcinoma of the larynx with thyroid papillary carcinoma is an unusual finding. From 2004 to 2011, approximately 250 patients underwent laryngectomies due to squamous cell carcinoma of the larynx at the Otolaryngology Department of Khalili Hospital, affiliated with Shiraz University of Medical Sciences, Shiraz, Iran. In three patients, synchronous occurrence of squamous cell carcinoma and thyroid papillary carcinoma was found. Histopathologic study of the lymph nodes revealed metastatic papillary thyroid carcinoma in one case. We report three cases of thyroid papillary carcinoma incidentally found on histological examinations of resected thyroid lobes, as a procedure required for treatment of head and neck squamous cell carcinoma. In comparison, laryngeal squamous cell carcinoma needs more aggressive treatment than well-differentiated thyroid carcinoma. The prevalence of thyroid papillary carcinoma, as an incidental finding in our study was 0.01%. Therefore, preoperative evaluation of the thyroid gland by ultrasonography and fine needle aspiration biopsy of suspicious lesions is recommended in patients who are candidates for open laryngectomy.

    Hepatocellular carcinoma (HCC) shows a high rate of recurrence after hepatectomy; predictive factors for early recurrence would help determine optimal therapeutic and management strategies. Among 163 patients with HCC undergoing hepatectomy with curative intent, 46 patients developed recurrence within 1 year. Clinicopathological data were retrospectively analyzed to identify predictive parameters for early recurrence. Survival rates in cases of recurrence within 1 year were worse than those of no recurrence within 1 year or recurrence after 1 year. Protein induced by vitamin K absence/antagonist II (PIVKA-II) greater than 150, positive fucosylated alpha-fetoprotein (L3-AFP), and deviancy from Milan criteria (MC) on preoperative imaging were associated with high risk of early recurrence and total number of these three risk factors predicted the survival. With multivariate analysis, (1) preoperatively, positive factors of two or more among three items of PIVKA-II, L3-AFP, and deviancy from MC; (2) and postoperatively, pathological cancer spread (microscopic vascular invasion and/or intrahepatic metastasis) both represented risks for early recurrence. A combination of three preoperative factors, PIVKA-II, L3-AFP, and MC status, in conjunction with the postoperative factor of cancer spread status represents a significant indicator for recurrence within 1 year. Improving the prognosis of patients with HCC would depend on how to adequately treat those at high risk of early recurrence.

    To evaluate the role of {sup 18}F-FDG PET/CT in the detection of recurrence in patients with oesophageal carcinoma, suspected clinically or following conventional investigations. This was a retrospective study. Data from 180 patients (age 56.3 ± 10.4 years; 126 men, 54 women) with histopathologically proven oesophageal carcinoma (squamous cell 115, adenocarcinoma 59, neuroendocrine carcinoma 4, small cell 1, poorly differentiated 1) who had undergone 227 {sup 18}F-FDG PET/CT studies for suspected recurrence were analysed. Recurrence was suspected clinically or following conventional investigations. PET/CT images were revaluated by two nuclear medicine physicians in consensus. Findings were grouped into local, nodal and distant recurrence. Results were compared to those from contrast-enhanced (CE) CT when available (109 patients). Clinical/imaging follow-up (minimum 6 months) with histopathology (when available) was taken as the reference standard. Of the 227 {sup 18}F-FDG PET/CT studies,166 were positive and 61 were negative for recurrent disease. PET/CT showed local recurrence in 134, nodal recurrence in 115 and distant recurrence in 47, with more than one site of recurrence in 34. The PET/CT findings were true-positive in 153 studies, true-negative in 54, false-positive in 13 and false-negative in 7. The sensitivity of {sup 18}F-FDG PET/CT was 96 %, the specificity was 81 %, the positive and negative predictive values were 92 % and 89 %, respectively, and the accuracy was 91 %. PET/CT showed similar accuracy in patients with squamous cell carcinoma and in those with adenocarcinoma (P = 0.181).{sup 18}F-FDG PET/CT was more specific than CECT (67 % vs. 21 %; P < 0.0001). PET/CT was superior to CECT for the detection of nodal recurrence (P < 0.0001), but not local recurrence (P = 0.093) or distant metastases (P = 0.441). {sup 18}F-FDG PET/CT shows high accuracy in the detection of suspected recurrence in patients with oesophageal carcinoma.

    Colon cancer is the second leading cause of death for cancer disease, after lung cancer, with nearly 18,000 deaths per year in Italy. In spite of the progress that have taken place over the past 30 years, little improvement has been gained in this dismal outcome, and the 5-year survival remains around 50%. Over one half of the patients will suffer from recurrence after a potentially curative resection. A major challenge lies in better detection of recurrences in order to diagnose those patients still amenable to curative resection. Locoregional recurrence is of particular interest and its frequency, diagnostic limitations and surgical treatment are herein discussed.

    Cancer is among most important causes of death in recent decades. Whoever the renal cell carcinoma incidence is low but it seems it is more complicated than the other cancers in terms of pathophysiology and treatments. The purpose of this work is to provide an overview and also deeper insight to renal cell carcinoma and the steps which have been taken to reach more specific treatment and target therapy, in this type of cancer by developing most effective agents such as Sorafenib. To achieve this goal hundreds of research paper and published work has been overviewed and due to limitation of space in a paper just focus in most important points on renal cell carcinoma, treatment of RCC and clinical development of Sorafenib. The information presented this paper shows the advanced of human knowledge to provide more efficient drug in treatment of some complicated cancer such as RCC in promising much better future to fight killing disease.

    Ductal carcinoma in situ (DCIS) is a non-obligate precursor of invasive breast cancer and a frequent mammographic finding requiring treatment. Up to 25% of DCIS can recur and half of recurrences are invasive, but there are no reliable biomarkers for recurrence. We hypothesised that copy number aberrations could predict likelihood of recurrence. We analysed a cohort of pure DCIS cases treated only with wide local excision for genome-wide copy number and loss of heterozygosity using Affymetrix OncoScan MIP arrays. Cases included those without recurrence within 7 years (n = 25) and with recurrence between 1 and 5 years after diagnosis (n = 15). Pure DCIS were broadly similar in copy number changes compared with invasive breast cancer, with the consistent exception of a greater frequency of ERBB2 amplification in DCIS. There were no significant differences in age or ER status between the cases with a recurrence vs those without. Overall, the DCIS cases with recurrence had more copy number events than the DCIS without recurrence. The increased copy number appeared non-random with several genomic regions showing an increase in frequency in recurrent cases, including 20 q gain, ERBB2 amplification and 15q loss. Copy number changes may provide prognostic information for DCIS recurrence, but validation in additional cohorts is required.

    Full Text Available Chemoradiotherapy is increasingly used in advanced laryngeal cancers. Failures are generally managed by surgery. They include histologically confirmed recurrent or residual disease or a symptomatic life threatening treatment sequelae. Tumour recurrence or residivism can be managed by chemotherapy when radical surgery is either refused by the patient or if the general condition of the patient do not permit it. However surgery becomes inevitable when life threatening treatment sequelae like absolute pharyngo-oesophageal stricture and aspiration sets in.

    2006-06-01

    Full Text Available Abstract Background It is widely accepted that vulvar carcinoma with a depth of invasion of less than one millimeter is sufficiently treated by vulvectomy or wide local excision without inguinal lymphadenectomy. Case presentation However, a patient with inguinal lymph node recurrence 21 months after radical vulvectomy for stage IA squamous cell carcinoma was observed. Conclusion According to a review of the literature, there are five additional cases of metastasizing vulvar cancer with a depth of invasion of less than one millimeter. Therefore, the definition of microinvasive carcinoma of the vulva based on depth of invasion alone may not be as reliable as previously thought and does not rule out inguinal lymph node involvement or recurrence. Consequently, the necessity of inguinal node dissection for microinvasive carcinoma needs to be discussed on an individual basis taking into account the age of the patient as well as the potential morbidity of extended surgery.

    AIM: To analyze the risk factors of hepatocellular carcinoma (HCC) recurrence after radiofrequency ablation (RFA) treatment with HCV-associated hepatitis. METHODS: Twenty-six patients with HCV-associated HCC who were followed-up for more than 12 mo were selected for this study. Risk factors for distant intrahepatic recurrences of HCC were evaluated for patients in whom complete coagulation was achieved without recurrence in the same subsegment as the primary nodule. Twelve clinical and tumoral factors were examined: Age, gender, nodule diameter, number of primary HCC nodule, Child-Pugh classification, serum platelet, serum albumin, serum AST, post RFA AST, serum ALT, post RFA ALT, post RFA treatment.RESULTS: Distant recurrences of HCC in remnant liver after RFA were observed in 14 cases and in the number of primary HCC nodules (P = 0.047), and the serum platelets (P = 0.030), the clear difference came out by the recurrence group and the non-recurrence group. The cumulative recurrence rates after 1 and 2 years were30.8% and 86.8%, respectively for primary multinodular HCC, and 15.4% and 29.5% respectively, for primary uninodular HCC. In addition the 1-year recurrence rates for patients with serum albumin more than 3.4 g/dL and less than 3.4 g/dL were 23.1% for both, but the 2-years recurrence rates were 89.0% and 23.1%, respectively. The number of primary HCC nodules (relative risk, 6.970; P = 0.016) were found to be a statistically significant predictor for poor distant intrahepatic recurrence by univariate analysis.CONCLUSION: Patients who have multiple HCC nodules, low serum platelets and low serum albumin accompanied by HCV infection, should be carefully followed because of the high incidence of new HCC lesions in the remnant liver, even if coagulation RFA is complete.

RESULTS: Progress in understanding the molecular basis of renal cell carcinoma, especially related to genetics and angiogenesis, has been achieved mainly through of the study of von Hippel-Lindau disease. A great variety of active agents have been developed and tested in metastatic renal cell carcinoma (mRCC patients. New specific molecular therapies in metastatic disease are discussed. Sunitinib, Sorafenib and Bevacizumab increase the progression-free survival when compared to therapy with cytokines. Temsirolimus increases overall survival in high-risk patients. Growth factors and regulatory enzymes, such as carbonic anhydrase IX may be targets for future therapies. CONCLUSIONS: A broader knowledge of clear cell carcinoma molecular biology has permitted the beginning of a new era in mRCC therapy. Benefits of these novel agents in terms of progression-free and overall survival have been observed in patients with mRCC, and, in many cases, have become the standard of care. Sunitinib is now considered the new reference first-line treatment for mRCC. Despite all the progress in recent years, complete responses are still very rare. Currently, many important issues regarding the use of these agents in the management of metastatic renal cancer still need to be properly addressed.

    BACKGROUND: E-cadherin is an epithelial cell adhesion molecule, and decreased E-cadherin expression in liver cancer is associated with poor prognosis. A -160 C→A polymorphism in the promoter region of E-cadherin has been reported to decrease gene transcription. This allelic variation may be a potential genetic marker for identifying those individuals at higher risk for invasive/metastatic disease. METHODS: The effect of E-cadherin gene polymorphism on risk of tumor recurrence was studied in 93 patients with hepatocellular carcinoma (HCC) after liver transplantation, and determined whether this polymorphism is a biomarker for the risk of tumor recurrence. RESULTS: The genotype frequencies in the patients with recurrence were C/C: 0.667, C/A: 0.311, and A/A:0.022, and in the patients without recurrence C/C:0.604, C/A: 0.271 and A/A: 0.125. No signiifcant difference was found between the two groups (P=0.171). Between -160 C→A polymorphism and the clinicopathological data, there were no statistically signiifcant differences in the distribution of the parameters as to age, gender, portal vein tumor thrombi, preoperative alpha-fetoprotein level, tumor size, or histopathological grading (P>0.05). CONCLUSION:The results of this study show no association exists between the E-cadherin genotype and the risk of tumor recurrence in Chinese patients with HCC.

    The purpose of this study was to evaluate treatment results in terms of the survival and failure patterns subsequent to radiation therapy in recurrent cervical cancer, following primary surgery. Between January 1990 and December 1999, 27 patients, with recurrent cervical cancer following primary surgery, were subsequently treated with radiation in the Department of Radiation Oncology, at the Keimyung University Dongsan Medical Center. Their median age was 48, ranging from 31 to 70 years old. With regard to the initial FIGO stage on presentation, 20 and 7 patients were stages I and II, respectively. Twenty three patients had squamous ceH carcinomas and 4 had adenocarcinomas. The time interval from the primary surgery to the recurrence ranged from 2 to 90 months with a median of 29 months. The recurrent sites were the vaginal cuff alone, the pelvic cavity and combined recurrence in 14, 9 and 4 patients, respectively. Radiation was performed, with external and vaginal intracavitary radiation in 13 patients, external radiation alone in 13 and vaginal intracavitary radiation alone in another one. The median follow-up period was 55 months, ranging from 6 to 128 months. The five year disease free survival (5y DFS) and five year overall survival (5y OS) rates were 68.2 and 71.9%, respectively. There was a marginal statistically significant difference in the 5y DFS in relation to the recurrent site (5y DFS, 85.7% in vaginal cuff recurrence alone, 53.3% in pelvic cavity recurrence, p=0.09). There was no difference in the survival according to the time interval between the primary surgery and a recurrence. There was only a 7% local failure rate in the patients with a vaginal cuff recurrence. The major failure patterns were local failure in the patients with pelvic cavity recurrence, and distant failure in the patients with a combined recurrence. There were no complications above grade 3 after the radiation therapy. Radiation therapy was safe and effective treatment for a

    AIM: To evaluate mutant p53 gene in primary hepatocellular carcinoma and to investigate the correlation between it and the recurrence of hepatocellular carcinoma.METHODS: Mutations of p53 gene were examined using antihuman p53 monoclonal antibody and immunohistochemical staining in 79 resected hepatocellular carcinomas. The correlations among variables of p53 positivity and invasiveness, disease free interval and survival were studied.In addition, in those who developed recurrence, the correlation among p53 positivity, clinical features and postrecurrence survival were also studied.RESULTS: Of these 79 cases, 64 (81%) had p53 mutation.Those patients with mutant p53 positivityhad significantly more tumor recurrence (76.6 % vs 40.0 %, P=0.0107).However, the COX proportional hazards model showed that p53 overexpression had only weak correlations with recurrence free interval and survival time (P=0.088 and 0.081), which was probably related to the short duration of follow-up. The invasiveness variables may be predictors of HCC recurrence. On univariate analysis, more patients with mutant p53 positivity had vascular permeation [78.1vs 40.0 %, P=0.0088, O.R. (odds ratio) =5.3], grade Ⅱ-ⅣV differentiation (98.4 vs 80.0 %, P=0.0203, O.R. =15.7), no complete capsule (82.8 vs 53.3 %, P=0.0346, O.R. =4.2)and daughter nodules (60.9 vs. 33.3 %, P=0.0527, O.R.=3.1) than patients with negative p53 staining. Onmultivariate analysis, only vascular permeation and grade of differentiation remained significant (P=0.042 and 0.012).There was no statistically significant correlation betweenthe status of p53 in the primary lesion and the clinical features of recurrent hepatocellular carcinomas examined,including extrahepatic metastasis (P=0.1103) and the number of recurrent tumors (P= 1.000) except for diseaseover more than one segment in the extent of recurrent tumors (P=0.0043). The post-recurrence median survival was lower in patients in whom p53 mutation had been detected in the

    NY-ESO-1 belongs to the cancer testis antigens (CTA) family, and is identified in a variety of tumors. Certain studies have demonstrated that NY-ESO-1 predicts tumor recurrence and treatment response. No reports are currently available regarding the correlation between NY-ESO-1 and the recurrence of hepatocellular carcinoma (HCC) following surgery. The purpose of the present study was to evaluate the association between NY-ESO-1 and relapse of HCC and to explore the possible mechanisms for this correlation. A total of 120 HCC patients were analyzed for the expression of NY-ESO-1 by immunohistochemistry (IHC). A stable NY-ESO-1 over-expressed HepG2 cell line (ESO-HepG2) was established to determine the biological effects of NY-ESO-1 on cell proliferation, cell cycle and migration by using the xCELLigence DP system, flow cytometry and xCELLigence SP system. NY-ESO-1 was positive in 28 of 120 (23.3%) HCC tumor tissues. NY-ESO-1 was not detectable in adjacent normal liver tissues. A close correlation was found between NY-ESO-1 expression and the recurrence of HCC following surgery (P=0.007). Kaplan-Meier analysis showed a shorter recurrence-free survival (RFS) for patients positive for NY-ESO-1 (log-rank test, P=0.003). The Cox regression model demonstrated that NY-ESO-1 expression was a significant independent predictor for the recurrence of HCC following curative surgery (P=0.022). Compared with HepG2 cells, ESO-HepG2 cells have increased migration but not proliferation ability. In conclusion, NY-ESO-1 expression is associated with worse HCC outcome following surgery, and the mechanism for this finding may be that NY-ESO-1 increases tumor cell migration.

    Ryosuke Tateishi

    Full Text Available BACKGROUND: In the treatment of hepatocellular carcinoma (HCC, hepatic resection has the advantage over radiofrequency ablation (RFA in terms of systematic removal of a hepatic segment. METHODS: We enrolled 303 consecutive patients of a single naïve HCC that had been treated by RFA at The University of Tokyo Hospital from 1999 to 2004. Recurrence was categorized as either intra- or extra-subsegmental as according to the Couinaud's segment of the original nodule. To assess the relationship between the subsegments of the original and recurrent nodules, we calculated the kappa coefficient. We assessed the risk factors for intra- and extra-subsegmental recurrence independently using univariate and multivariate Cox proportional hazard regression. We also assessed the impact of the mode of recurrence on the survival outcome. RESULTS: During the follow-up period, 201 patients in our cohort showed tumor recurrence distributed in a total of 340 subsegments. Recurrence was categorized as exclusively intra-subsegmental, exclusively extra-subsegmental, and simultaneously intra- and extra-subsegmental in 40 (20%, 110 (55%, and 51 (25% patients, respectively. The kappa coefficient was measured at 0.135 (95% CI, 0.079-0.190; P<0.001. Multivariate analysis revealed that of the tumor size, AFP value and platelet count were all risk factors for both intra- and extra-subsegmental recurrence. Of the patients in whom recurrent HCC was found to be exclusively intra-subsegmental, extra-subsegmental, and simultaneously intra- and extra-subsegmental, 37 (92.5%, 99 (90.8% and 42 (82.3%, respectively, were treated using RFA. The survival outcomes after recurrence were similar between patients with an exclusively intra- or extra-subsegmental recurrence. CONCLUSIONS: The effectiveness of systematic subsegmentectomy may be limited in the patients with both HCC and chronic liver disease who frequently undergo multi-focal tumor recurrence.

    AIM: To investigate the clinicopathological risk factors for immediate post-operative fatal recurrence of hepatocellular carcinoma (HCC), which may have practical implication and contribute to establishing high risk patients for pre- or post-operative preventive measures against HCC recurrence.METHODS: From June 1994 to May 2004, 269 patients who received curative resection for HCC were reviewed.Of these patients, those who demonstrated diffuse intrahepatic or multiple systemic recurrent lesions within 6mo after surgery were investigated (fatal recurrence group). The remaining patients were designated as the control group, and the two groups were compared for clinicopathologic risk factors.RESULTS: Among the 269 patients reviewed, 30patients were enrolled in the fatal recurrence group.Among the latter, 20 patients showed diffuse intrahepatic recurrence type and 10 showed multiple systemic recurrence type. Multivariate analysis between the fatal recurrence group and control group showed that preoperative serum alpha-fetoprotein (AFP) level was greater than 1 000 μg/L (P=0.02; odds ratio= 2.98),tumor size greater than 6.5 cm (P=0.03; OR=2.98),and presence of microvascular invasion (P= 0.01;OR=4.89) were the risk factors in the fatal recurrence group. The 48.1% of the patients who had all the three risk factors and the 22% of those who had two risk factors experienced fatal recurrence within 6 mo after surgery.CONCLUSION: Three distinct risk factors for immediate post-operative fatal recurrence of HCC after curative resection are pre-operative serum AFP level>1 000 μg/L,tumor size>6.5 cm, and microvascular invasion. The high risk patients with two or more risk factors should be the candidates for various adjuvant clinical trials.

    Full Text Available It is well known that the presence of end-stage liver disease increases the risk of developing hepatocellular carcinoma (HCC. Liver transplantation (LT for patients within the Milan criteria has become a standard treatment for HCC in most developed centers worldwide. However, a major cause of death in cirrhotic patients with HCC after transplantation is tumor recurrence, including peritoneal recurrences, which develops rarely but presents a significant problem with regard to their management. Our experience includes two cases with HCC within the Milan criteria of peritoneal recurrences after living donor LT. Both patients had interventions for HCC in their medical history before LT, and we propose that these might have been a possible cause of the HCC peritoneal recurrence.

    Purpose: To evaluate the safety and efficacy of CT-guided radiofrequency (RF) ablation for the palliative treatment of recurrent unresectable rectal tumors. Materials and Methods: Twenty-seven patients with locally recurrent rectal cancer were treated with computed tomography (CT)-guided RF ablation. Therapy was performed with the patient under conscious sedation with a seven- or a nine-array expandable RF electrode for 8-10 min at 80-110 Degree-Sign C and a power of 90-110 W. All patients went home under instructions the next day of the procedure. Brief Pain Inventory score was calculated before and after (1 day, 1 week, 1 month, 3 months, and 6 months) treatment. Results: Complete tumor necrosis rate was 77.8% (21 of a total 27 procedures) despite lesion location. BPI score was dramatically decreased after the procedure. The mean preprocedure BPI score was 6.59, which decreased to 3.15, 1.15, and 0.11 at postprocedure day 1, week 1, and month 1, respectively, after the procedure. This decrease was significant (p < 0.01 for the first day and p < 0.001 for the rest of the follow-up intervals (paired Student t test; n - 1 = 26) for all periods during follow-up. Six patients had partial tumor necrosis, and we were attempted to them with a second procedure. Although the necrosis area showed a radiographic increase, no complete necrosis was achieved (secondary success rate 65.6%). No immediate or delayed complications were observed. Conclusion: CT-guided RF ablation is a minimally invasive, safe, and highly effective technique for treatment of malignant rectal recurrence. The method is well tolerated by patients, and pain relief is quickly achieved.

    Primary candidiasis is rare and often confused with a pre-cancerous lesion, squamous cell carcinoma, or verrucous carcinoma. We report an extremely rare case of squamous cell carcinoma of the vocal cord following primary candidiasis. A 62-year-old man presented to our department reporting a 1-month history of hoarseness. He underwent laryngeal microscopic surgery for a presumptive diagnosis of glottic carcinoma. Histopathologic examination revealed candidiasis and scattered moderate dysplasia. He was treated with itraconazole for 4 weeks, and followed up without any recurrence of candidiasis. However, the 42-month follow-up examination revealed a focal whitish lesion on the right true vocal cord, and a repeat biopsy of this area revealed squamous cell carcinoma without evidence of candidiasis. The patient was treated with radiotherapy and remains well with no signs of tumor recurrence or candidiasis.

    Full Text Available Background. To describe the clinical characteristics of the patients who suffered from relapse after conventional irradiation for nasopharyngeal carcinoma (NPC. Methods. Three hundred and fifty-one consecutive patients with first-time recurrent NPC between January 1999 and July 2005 were included. The patients’ clinical data were reviewed, including recurrent interval time, symptoms, signs, imaging characteristics, pathologic features, and restaging. Results. The median interval of relapse was 26.0 months. The most common symptoms in symptomatic patients were nasal bloody discharge (37.9% and headache (31.1%. Local recurrence alone accounted for 73.5%. Most patients were restaged as stage III (23.1% and stage IV (51.1%. Subgroup analysis suggested a significantly higher proportion of the long-latent relapses originated from early primary. A series of postreirradiation complications were more frequent in patients with longer latency at reception. Conclusions. Most recurrent nasopharyngeal carcinoma is advanced disease. Patients with different recurrent interval time show different nature behavior.

    BACKGROUND: Hepatocellular carcinoma (HCC) recurrence remains a key issue after liver transplantation. This study aimed to determine a subgroup of HCC patients within the Milan criteria who could achieve a theoretical goal of zero re-currence rates after liver transplantation. METHODS: Between 1999 and 2009, 179 patients who re-ceived liver transplantation for HCC within the Milan criteria were retrospectively included. Analysis of the factors associ-ated with HCC recurrence was performed to determine the subgroup of patients at the lowest risk of recurrence. RESULTS: Seventy-two percent of the patients received a bridging therapy, including 54 liver resections. Eleven (6.1%) patients recurred within a delay of 19±22 months and ulti-mately died. Factors associated with recurrence were serum alpha-fetoprotein level >400 ng/mL, satellite nodules, poor differentiation, microvascular invasion and cholangiocarci-noma component. Recurrence rates decreased from 6.1% to 3.1% in patients without any of these factors. CONCLUSIONS: Among HCC patients within the Milan cri-teria, selecting patients with factors based on histology would allow tending towards zero recurrence, and prior histological assessment by liver biopsy or resection may be essential to rule out poorly differentiated tumors, microvascular invasion, and cholangiocarcinoma component.

  10. Vismodegib (ERIVEDGE°) In basal cell carcinoma: too many unknowns.

    Science.gov (United States)

    2015-01-01

    Basal cell carcinomas are the most common skin cancers. They are usually localised and carry a good prognosis. There is no standard treatment for the rare patients with metastatic basal cell carcinoma or very extensive basal cell carcinoma for whom surgery or radiotherapy is inappropriate. Vismodegib, a cytotoxic drug, is claimed to prevent tumour growth by inhibiting a pathway involved in tissue repair and embryogenesis. It has been authorised in the European Union for patients with metastatic or locally advanced and extensive basal cell carcinoma. Clinical evaluation of vismodegib is based on a non-comparative clinical trial involving 104 patients, providing only weak evidence. Twenty-one months after the start of the trial, 7 patients with metastases (21%) and 6 patients with advanced basal cell carcinoma (10%) had died. Given the lack of a placebo group, there is no way of knowing whether vismodegib had any effect, positive or negative, on survival. There were no complete responses among patients with metastases, but about one-third of them had partial responses. Among the 63 patients with locally advanced basal cell carcinoma, there were 14 complete responses and 16 partial responses. The recurrence rate in patients with complete responses was not reported. Similar results were reported in two other uncontrolled trials available in mid-2014. Vismodegib has frequent and sometimes serious adverse effects, including muscle spasms, fatigue and severe hyponatraemia. Cases of severe weight loss, alopecia, ocular disorders, other cancers (including squamous cell carcinoma) and anaemia have also been reported. More data are needed on possible hepatic and cardiovascular adverse effects. A potent teratogenic effect was seen in experimental animals. As vismodegib enters semen, contraception is mandatory for both men (condoms) and women. In practice, vismodegib has frequent and varied adverse effects, some of which are serious, while its benefits are poorly documented

    Purpose: The purpose of this study was to compare the capability of integrated FDG-PET/CT for assessment of postoperative intra- and extrathoracic recurrence in non-small cell lung cancer (NSCLC) patients with that of standard radiological examinations. Materials and methods: A total of 121 consecutive pathologically diagnosed NSCLC patients (80 males, 41 females; mean age, 71 years) underwent pathologically and surgically confirmed complete resection, followed by prospective integrated FDG-PET/CT and standard radiological examinations. Final diagnosis of recurrence was based on the results of more than 12 months of follow-up and/or pathological examinations. The probability of recurrence was assessed with either method for each patient by using 5-point visual scoring system, and final diagnosis was made by consensus between two readers. ROC analysis was used to compare the capability of the two methods for assessment of postoperative recurrence on a per-patient basis. The ROC-based positive test was used to determine optimal cut-off value for FDG uptake measurement at a site suspected on the basis of qualitatively assessed PET/CT. Finally, sensitivities, specificities and accuracies of all methods were compared by means of McNemar's test. Results: Areas under the curve of qualitatively assessed PET/CT and standard radiological examinations showed no significant differences (p > 0.05). At an optimal cut-off value of 2.5, specificity and accuracy of quantitatively and qualitatively assessed PET/CT were significantly higher than those of qualitatively assessed PET/CT and standard radiological examinations (p < 0.05). Conclusion: Accuracy of assessment of postoperative intra- and extrathoracic recurrence in NSCLC patients by qualitative and/or quantitative FDG-PET/CT is equivalent to or higher than that by standard radiological examinations.

    We report a case of isolated gastrointestinal metastasis from breast lobular carcinoma, which mimicked primary anal cancer. In July 2000, an 88-year-old woman presented with infiltrating lobular cancer (pT1/G2/N2). The patient received postoperative radiotherapy and hormonal therapy. Four years later,she presented with an anal polypoid lesion. The mass was removed for biopsy. Immunohistochemical staining suggested a breast origin. Radiotherapy was chosen for this patient, which resulted in complete regression of the lesion. The patient died 3 years after the first manifestation of gastrointestinal metastasis.According to the current literature, we consider the immunohistochemistry features that are essential to support the suspicion of gastrointestinal breast metastasis, and since we consider the gastrointestinal involvement as a sign of systemic disease, the therapy should be less aggressive and systemic.

  13. Radiotherapy of presacral recurrence following radical surgery for rectal carcinoma

    The records of 58 patients treated by radiotherapy for presacral recurrent rectal cancers between 1975 and 1982 were evaluated. Pain was one of the most distressing symptoms, occurring in 38 of 58 patients (66 percent) which, in 90 percent (34 of 38) of patients could be controlled by radiotherapy. Side effects were mild, and could be treated conservatively. The crude survival of the patients was 19.8 months (range, 3 to 71 months). Only 3 percent of those treated survived five years. The dose-survival study showed increased survival of patients treated with more than 44 Gy. Because of negative selection of patients irradiated with lower doses, certain conclusions cannot be made. Surgery, if performed radically, is the treatment of choice. But patients with inoperable disease treated with radiotherapy benefit symptomatically, and might have increased survivals with a small chance of cure.

    Purpose: To examine the rate of local recurrence according to the margin status for patients with pure ductal carcinoma in situ (DCIS) treated by mastectomy. Methods and Materials: One hundred forty-five consecutive women who underwent mastectomy with or without radiation therapy for DCIS from 1998 to 2005 were included in this retrospective analysis. Only patients with pure DCIS were eligible; patients with microinvasion were excluded. The primary endpoint was local recurrence, defined as recurrence on the chest wall; regional and distant recurrences were secondary endpoints. Outcomes were analyzed according to margin status (positive, close (≤2 mm), or negative), location of the closest margin (superficial, deep, or both), nuclear grade, necrosis, receptor status, type of mastectomy, and receipt of hormonal therapy. Results: The primary cohort consisted of 142 patients who did not receive postmastectomy radiation therapy (PMRT). For those patients, the median follow-up time was 7.6 years (range, 0.6-13.0 years). Twenty-one patients (15%) had a positive margin, and 23 patients (16%) had a close (≤2 mm) margin. The deep margin was close in 14 patients and positive in 6 patients. The superficial margin was close in 13 patients and positive in 19 patients. One patient experienced an isolated invasive chest wall recurrence, and 1 patient had simultaneous chest wall, regional nodal, and distant metastases. The crude rates of chest wall recurrence were 2/142 (1.4%) for all patients, 1/21 (4.8%) for those with positive margins, 1/23 (4.3%) for those with close margins, and 0/98 for patients with negative margins. PMRT was given as part of the initial treatment to 3 patients, 1 of whom had an isolated chest wall recurrence. Conclusions: Mastectomy for pure DCIS resulted in a low rate of local or distant recurrences. Even with positive or close mastectomy margins, the rates of chest wall recurrences were so low that PMRT is likely not warranted.

    Full Text Available Sebaceous carcinoma is a rare malignancy of the skin appendages. It tends to occur in elderly patients. Orbital region is the most commonly involved site seen in 75% of cases. The involvement of extra-orbital sites is infrequent. Herein, a case of extra-ocular sebaceous carcinoma arising in the scalp of a 20-year-old man is described.The patient developed tumor relapse after excision biopsy. He was treated with wide local excision of the tumor. However, the patient developed local recurrence after an interval of four months for which he again underwent wide local excision. He did not manifest any regional or distant metastases. In view of the locally aggressive tumor, he received adjuvant radiation therapy. The patient was successfully treated with no evidence of any local recurrence seen after a follow-up period of one year. The timely recognition of sebaceous carcinoma is imperative so as to execute the primary treatment i.e., wide local excision. Adjuvant radiotherapy may be considered to improve the clinical outcome for recurrent tumors.

    Background The two isoforms of carcinoembryonic antigen-related cell adhesion molecule 1 (CEACAM1), 1 with a long cytoplasmic domain (CEACAM1-L) and 1 with a short (CEACAM1-S), are involved in different signaling pathways. β2-spectrin (β2SP) is an adaptor protein that plays critical roles in the proper control of Smad access to activate receptors involved in regulation of TGF-β signaling. In this study, we examined the association between CEACAM1 isoform balance and hepatocellular carcinoma (HCC) malignant potential and investigated the possibility of a molecular interaction between CEACAM1 and β2SP. Methods Immunohistochemical analysis was carried out with CEACAM1-L or CEACAM1-S antibodies on 154 HCC tissues to correlate with the factors of malignancy. Invasion assay was performed for the effect of CEACAM1 expression on HCC cell lines. Moreover, immunohistochemical analysis and immunoprecipitation analysis were performed to investigate the association between CEACAM1 isoform balance and β2SP. Results In immunohistochemical analysis, CEACAM1-L expression dominance was a risk factor for HCC recurrence (p = 0.04) and was significantly associated with a shorter survival compared with CEACAM1-S expression dominance. Invasion assay indicated that CEACAM1-4L-transfected HLF and PLC/PRF/5 cells showed significantly increased invasion (p<0.0001) and CEACAM1-4S-transfected HLF cells showed significantly decreased invasion. Immunohistochemical analysis of β2SP suggested that the HCCs with CEACAM1-L-dominant expression were more strongly stained with β2SP than the HCCs with CEACAM1-S-dominant expression (p = 0.013), and coprecipitation assays indicated that CEACAM1-L could bind to β2SP. Conclusions CEACAM1-L may enhance the HCC invasiveness through an interaction with β2SP and subsequent effects on TGF-β signaling. PMID:24390710

    Trichoepitheliomas (TE) are benign tumours but occasionally can undergo transformation to malignant neoplasms more commonly as Basal Cell Carcinoma (BCC). The correct diagnosis between these tumours is very important because basal cell carcinoma is locally aggressive neoplasm and requires total surgical excision with wide healthy margins while trichoepithelioma needs simple excision. We describe three patients who developed basal cell carcinoma with facial trichoepitheliomas. The only clinical feature that distinguished the carcinomas from the trichoepitheliomas was their larger size, in all three patients, one patient with recurrent, hyper pigmented swelling with surface ulceration and in another patient there are multiple trichoepitheliomas, and other family members are also affected. The history, clinical features and histopathological findings were suggestive of the evolution of basal cell carcinoma directly from trichoepithelioma in our first two cases, but in the third case TE and BCC were separate lesions on face and we are uncertain about whether the BCC developed independently or by transformation from a trichoepithelioma. Based on our clinicopathological observations in the three patients and reports in the recent literature, BCC with follicular differentiation and trichoepithelioma are considered to be highly related.

We hypothesize that activation of the SHH pathway contributes to the recurrence of breast carcinoma.Methods: Fifty consecutive patients with invasive breast carcinoma following curative resection were enrolled in this prospective study. The ratios of messenger RNA (mRNA expression for Sonic Hedgehog (SHH, patched homolog-1 (PTCH-1, glioma-associated oncogene-1 (GLI-1, and smoothened (SMOH were measured between breast carcinoma tissue and paired noncancerous breast tissue. These ratios were compared with their clinicopathologic characteristics. These factors and the mRNA ratios were compared between patients with recurrence and those without recurrence.Results: The size of the invasive cancer correlated significantly with the ratio of SHH mRNA (P=0.001, that of PTCH-1 mRNA (P=0.005, and that of SMOH mRNA (P=0.021. Lymph node involvement correlated significantly with the ratio of SMOH mRNA (P=0.041. The correlation between Her-2 neu and the ratio of GLI-1 mRNA was statistically significant (P=0.012. Each ratio of mRNA of SHH, PTCH-1, GLI-1, and SMOH correlated significantly with cancer recurrence (P<0.001 for each.Conclusion: We suggest that high expression of SHH mRNA, PTCH-1 mRNA, GLI-1 mRNA, and SMOH mRNA in breast cancer tissue correlates with invasiveness and is a potential biomarker to predict postoperative recurrence.Keywords: SHH pathway, breast carcinoma, prediction, recurrence

    2013-01-01

    Full Text Available Merkel cell carcinoma (MCC of the skin is a rare, aggressive, malignant neuroendocrine neoplasm. The tumor classically demonstrates positive immunohistochemistry (IHC staining for chromogranin A(ChrA, cytokeratin 20 (CK20, neuron specific enolase (NSE and/or achaete-acute complex-like 1 (MASH1. The newly identified Merkel cell polyomavirus (MCPyV has been found to be associated with most MCC cases. The primary histologic differential diagnoses of cutaneous MCC is small cell primary bronchogenic carcinoma (SCLC; moreover, both are of neuroendocrine origin. SCLC accounts for approximately 10-15% of all primary lung cancer cases; this histologic subtype is a distinct entity with biological and oncological features distinct from non-small cell lung cancer (NSCLC. In contradistinction to MCC, SCLC is classically IHC positive for cytokeratin 7 (CK7 and transcription factor (TTF-1. Similar to SCLC, MCC cell lines may be classified into two different biochemical subgroups designated as Classic and Variant. In our review and case report, we aim to emphasize the importance of a multidisciplinary approach to the approach to this difficult differential diagnosis. We also aim to comment about features of the cells of origin of MCC and SCLC; to summarize the microscopic features of both tumors; and to review their respective epidemiologic, clinical, prognostic and treatment features. We want to emphasize the initial workup study of the differential diagnosis patient, including evaluating clinical lymph nodes, a clinical history of any respiratory abnormality, and chest radiogram. If a diagnosis of primary cutaneous MCC is confirmed, classic treatment includes excision of the primary tumor with wide margins, excision of a sentinel lymph node, and computed tomography, positron emission tomography and/or Fluorine-18-fluorodeoxyglucose positron emission tomography scan studies

    2007-01-01

    Objective: To investigate the clinicopathological risk factors for fatal recurrence of hepatocellular carcinoma (HCC) in orthotopic liver transplant recipients in the first year. Methods: From April 2002 to October 2005, 303 recipients who received orthotopic liver transplantation for HCC were reviewed. Of These patients, those who demonstrated diffuse intra-hepatic or multiple systemic recurrent lesions and died within 1 y after surgery were investigated (fatal recurrence group, 48 cases). The remaining patients were designated as the control group, and the two groups were compared for clinicopathologic risk factors by logistic regression analysis. Results: Among the 303 patients reviewed, 48 patients were enrolled in the fatal recurrence group (15.84%). Multivariate analysis between the fatal recurrence group and control group showed that the presence of vascular invasion, tumor size greater than 6.5 cm, and pre-operative serum alpha-fetoprotein (AFP) level greater than 1000 μg/L were the risk factors in the fatal recurrence group. 85.71% of the patients who had all the three risk factors, 37.84% of those who had two risk factors, 13.64% of those who had one risk factors, and 6.71% of those who had none risk factors died because of recurrence within 1 y after transplantation. Conclusion: Three distinct risk factors attributed to fatal recurrence of liver transplant recipients for HCC are vascular invasion, tumor size ≥6.5 cm, and pre-operative serum AFP level ≥1000 μg/L. The high risk HCC patients with two or more risk factors should not to be the candidates for liver transplantation.

    Background Heparanase is an enzyme that cleaves heparan sulfate chains. Oligosaccharides generated by heparanase induce tumor progression. Basal cell carcinoma and squamous cell carcinoma comprise types of nonmelanoma skin cancer. Objectives Evaluate the glycosaminoglycans profile and expression of heparanase in two human cell lines established in culture, immortalized skin keratinocyte (HaCaT) and squamous cell carcinoma (A431) and also investigate the expression of heparanase in basal cell carcinoma, squamous cell carcinoma and eyelid skin of individuals not affected by the disease (control). Methods Glycosaminoglycans were quantified by electrophoresis and indirect ELISA method. The heparanase expression was analyzed by quantitative RT-PCR (qRTPCR). Results The A431 strain showed significant increase in the sulfated glycosaminoglycans, increased heparanase expression and decreased hyaluronic acid, comparing to the HaCaT lineage. The mRNA expression of heparanase was significantly higher in Basal cell carcinoma and squamous cell carcinoma compared with control skin samples. It was also observed increased heparanase expression in squamous cell carcinoma compared to the Basal cell carcinoma. Conclusion The glycosaminoglycans profile, as well as heparanase expression are different between HaCaT and A431 cell lines. The increased expression of heparanase in Basal cell carcinoma and squamous cell carcinoma suggests that this enzyme could be a marker for the diagnosis of such types of non-melanoma cancers, and may be useful as a target molecule for future alternative treatment.

    We report an 80-year-old man who presented with spontaneous regression of hepatocellular carcinoma (HCC). He complained of sudden right flank pain and low-grade fever.The level of protein induced by vitamin K antagonist (PIVKA)-Ⅱ was 1 137 mAU/mL. A computed tomography scan in November 2000 demonstrated a low-density mass located in liver S4 with marginal enhancement and a cystic mass of 68 mmx55 mm in liver S6, with slightly high density content and without marginal enhancement. Angiography revealed that the tumor in S4 with a size of 25 mm×20 mm was a typical hypervascular HCC, and transarterial chemoembolization was performed. However, the tumor in S6 was hypovascular and atypical of HCC, and thus no therapy was given. In December 2000, the cystic mass regressed spontaneously to 57 mmx44 mm, and aspiration cytology revealed bloody fluid, and the mass was diagnosed cytologically as class Ⅰ.The tumor in S4 was treated successfully with a 5 mm margin of safety around it. The PⅣKA-Ⅱ level normalized in February2001. In July 2001, the tumor regressed further but presented with an enhanced area at the posterior margin. In November2001, the enhanced area extended, and a biopsy revealed well-differentiated HCC, although the previous tumor in S4 disappeared. Angiography demonstrated two tumor stains, one was in S6, which was previously hypovascular,and the other was in S8. Subsequently, the PⅣKA-Ⅱ level started to rise with the doubling time of 2-3 wk, and the tumor grew rapidly despite repeated transarterial embolization with gel foam. In February 2003, the patient died of bleeding into the peritoneal cavity from the tumor that occupied almost the entire right lobe. Considering the acute onset of the symptoms, we speculate that local ischemia possibly due to rapid tumor growth, resulted in intratumoral bleeding and/or hemorrhagic necrosis, and finally spontaneous regression of the initial tumor in S6.

    Full Text Available Background: Careful hepatocellular carcinoma (HCC case selection permits orthotopic liver transplantation with the expectation of around 70% plus 5-year survival. However, many patients have tumor recurrences and there is little literature guidance in the management of these patients. Aims: A retrospective examination of patients transplanted with HCC who subsequently developed liver recurrence. Methods: A case cohort series of patients was prospectively followed who had liver-only multifocal tumor recurrence of HCC after liver transplant and were then treated with chemoembolization. Results: All 6 patients had recurrent HCC. 2 had no response, 1 had stable disease, 2 had partial response (PR and 1 had complete disappearance (CR of disease. Their survival (in months was: 13 (no response, 18 (no response, 12 (stable disease, 19 (PR, 30 (PR and 50 (CR. There were no liver toxicities. Conclusions: Chemoembolization for tumor recurrence in the transplanted liver is as safe as or safer than in the pre-transplant liver, due to the absence of cirrhosis. In this series, there were 3 of 6 responses with some long survivors.

    Full Text Available BACKGROUND: Typically observed at 2 y after surgical resection, late recurrence is a major challenge in the management of hepatocellular carcinoma (HCC. We aimed to develop a genomic predictor that can identify patients at high risk for late recurrence and assess its clinical implications. METHODS AND FINDINGS: Systematic analysis of gene expression data from human liver undergoing hepatic injury and regeneration revealed a 233-gene signature that was significantly associated with late recurrence of HCC. Using this signature, we developed a prognostic predictor that can identify patients at high risk of late recurrence, and tested and validated the robustness of the predictor in patients (n = 396 who underwent surgery between 1990 and 2011 at four centers (210 recurrences during a median of 3.7 y of follow-up. In multivariate analysis, this signature was the strongest risk factor for late recurrence (hazard ratio, 2.2; 95% confidence interval, 1.3-3.7; p = 0.002. In contrast, our previously developed tumor-derived 65-gene risk score was significantly associated with early recurrence (p = 0.005 but not with late recurrence (p = 0.7. In multivariate analysis, the 65-gene risk score was the strongest risk factor for very early recurrence (<1 y after surgical resection (hazard ratio, 1.7; 95% confidence interval, 1.1-2.6; p = 0.01. The potential significance of STAT3 activation in late recurrence was predicted by gene network analysis and validated later. We also developed and validated 4- and 20-gene predictors from the full 233-gene predictor. The main limitation of the study is that most of the patients in our study were hepatitis B virus-positive. Further investigations are needed to test our prediction models in patients with different etiologies of HCC, such as hepatitis C virus. CONCLUSIONS: Two independently developed predictors reflected well the differences between early and late recurrence of HCC at the molecular level and provided new

    Purpose: Local recurrences of nasopharyngeal carcinoma (NPC) may be salvaged by reirradiation with conventional techniques, but with significant morbidity. Intensity-modulated radiation therapy (IMRT) may improve the therapeutic ratio by reducing doses to normal tissue. The aim of this study was to address the efficacy and toxicity profile of IMRT for a cohort of patients with locally recurrent NPC. Methods and Materials: Between August 2003 and June 2009, 70 patients with radiologic or pathologically proven locally recurrent NPC were treated with IMRT. The median time to recurrence was 30 months after the completion of conventional radiation to definitive dose. Fifty-seven percent of the tumors were classified asrT3-4. The minimum planned doses were 59.4 to 60 Gy in 1.8- to 2-Gy fractions per day to the gross disease with margins, with or without chemotherapy. Results: The median dose to the recurrent tumor was 70 Gy (range, 50-77.4 Gy). Sixty-five patients received the planned radiation therapy; 5 patients received between 50 and 60 Gy because of acute side effects. With a median follow-up time of 25 months, the rates of 2-year locoregional recurrence-free survival, disease-free survival, and overall survival were 65.8%, 65.8%, and 67.4%, respectively. Moderate to severe late toxicities were noted in 25 patients (35.7%). Eleven patients (15.7%) had posterior nasal space ulceration, 17 (24.3%) experienced cranial nerve palsies, 12 (17.1%) had trismus, and 12 (17.1%) experienced deafness. Extended disease-free interval (relative risk 2.049) and advanced T classification (relative risk 3.895) at presentation were adverse prognostic factors. Conclusion: Reirradiation with IMRT provides reasonable long-term control in patients with locally recurrent NPC.

    Androgen-independent, human prostate carcinoma cells (DU145) develop into solid, carcinomatous xenotransplants on the diaphragm of nu/nu mice. Tumors encompass at least two poorly differentiated cell types: a rapidly dividing, eosinophilic cell comprises the main cell population and a few, but large basophilic cells able to invade the peritoneal stroma, the muscular tissue, lymph vessels. Poor cell contacts, intracytoplasmic lumina, and signet cells are noted. Lysosomal activities are reflected by entoses and programmed cell deaths forming cribriform carcinomas. In large tumors, degraded cells may align with others to facilitate formation of blood supply routes. Malignant cells would spread via ascites and through lymphatics.

    The extension of carcinoma to the cribriform plate is a poor prognostic finding. Two extremes of treatment approach have been advocated. On the one hand, patients may be abandoned to palliative chemotherapy. On the other hand, heroic and aggressive resections may be advocated including combined neurosurgical transdural and otolaryngologic facial-orbital resection. Armed with the surgical microscope and the CO2 laser there may be a place for a middle ground of therapy. We present our experience with recurrent tumor after full course radiation therapy and maxilloethmoidectomy. The biopsy proven recurrences were found at the cribriform plate but could not be shown to have crossed into the anterior cranial fossa by polytomography or high resolution CT scanning. The CO2 surgical laser delivered through the surgical microscope was used with repeated applications. Recurrent epidermoid carcinoma found to be confined to the nasal side of the cribriform plate can be controlled by careful microscopic stripping of soft tissue from the cribriform plate with a surgical laser.

Liver CSCs have emerged as an important therapeutic target against HCC. Numerous surface markers for liver CSCs have been identified, and include CD133, CD90, CD44, CD13, and epithelial cell adhesion molecules. These surface markers serve not only as tools for identifying and isolating liver CSCs but also as therapeutic targets for eradicating these cells. In studies of animal models and large-scale genomic analyses of human HCC samples, many signaling pathways observed in normal stem cells have been found to be altered in liver CSCs, which accounts for the stemness and aggressive behavior of these cells. Antibodies and small molecule inhibitors targeting the signaling pathways have been evaluated at different levels of preclinical and clinical development. Another strategy is to promote the differentiation of liver CSCs to less aggressive HCC that is sensitive to conventional chemotherapy. Disruption of the tumor niche essential for liver CSC homeostasis has become a novel strategy in cancer treatment. To overcome the challenges in developing treatment for liver CSCs, more research into the genetic makeup of patient tumors that respond to treatment may lead to more effective therapy. Standardization of HCC CSC tumor markers would be helpful for measuring the CSC response to these agents. Herein, we review the current strategies for developing treatment to eradicate liver CSCs and to improve the outcome for patients with

    BACKGROUND Surgical excision is the treatment of choice for basal cell carcinoma and micrographic surgery considered the gold standard, however not yet used routinely worldwide available, as in Brazil. Considering this, a previously developed treatment guideline, which the majority of tumors were treated by conventional technique (not micrographic) was tested. OBJECTIVE To establish the recurrence rate of basal cell carcinomas treated according to this guideline. METHOD Between May 2001 and July 2012, 919 basal cell carcinoma lesions in 410 patients were treated according to the proposed guideline. Patients were followed-up and reviewed between September 2013 and February 2014 for clinical, dermatoscopic and histopathologic detection of possible recurrences. RESULTS After application of exclusion criteria, 520 lesions were studied, with 88.3% primary and 11.7% recurrent tumors. Histological pattern was indolent in 85.5%, 48.6% were located in high risk areas and 70% small tumors. Only 7.3% were treated by Mohs micrographic surgery. The recurrence rate, in an average follow-up period of 4.37 years, was 1.3% for primary and 1.63% for recurrent tumors. Study limitations: unicenter study, with all patients operated on by the same surgeon. CONCLUSION The treatment guideline utilized seems a helpful guide for surgical treatment of basal cell carcinoma, especially if micrographic surgery is not available. PMID:28099591

    To evaluate the efficacy of radiofrequency ablation (RFA) in the treatment of loco-regional, recurrent, and well-differentiated thyroid carcinoma. Thirty-five recurrent well-differentiated thyroid carcinomas (RTC) in 32 patients were treated with RFA, between March 2008 and October 2011. RTCs were detected by regular follow-up ultrasound and confirmed by biopsy. All patients had fewer than 3 RTCs in the neck and were at high surgical risk or refused to undergo repeated surgery. Average number of RFA sessions were 1.3 (range 1-3). Post-RFA biopsy and ultrasound were performed. The mean follow-up period was 30 months. Pre- and post-RFA serum thyroglobulin values were evaluated. Thirty-one patients with 33 RTCs were treated with RFA only, whereas 1 patient with 2 RTCs was treated with RFA followed by surgery. At the last follow-up ultrasound, 31 (94%) of the 33 RTCs treated with RFA alone completely disappeared and the remaining 2 (6%) RTCs showed decreased volume. The largest diameter and volume of the 33 RTCs were markedly decreased by 93.2% (from 8.1 +/- 3.4 mm to 0.6 +/- 1.8 mm, p < 0.001) and 96.4% (from 173.9 +/- 198.7 mm{sup 3} to 6.2 +/- 27.9 mm{sup 3}, p < 0.001), respectively. Twenty of the 21 RTCs evaluated with post-RFA biopsies (95%) were negative for malignancy. One (5%) showed remaining tumor that was removed surgically. The serum thyroglobulin was decreased in 19 of 26 patients (73%). Voice change developed immediately after RFA in 6 patients (19%) and was spontaneously recovered in 5 patients (83%). Radiofrequency ablation can be effective in treating loco-regional, recurrent, and well-differentiated thyroid carcinoma in patients at high surgical risk.

    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.

    2000-01-01

    Hepatocellular carcinoma (HCC) is one of the most common malignancies in China. To date, surgery is still the best solution to it. However, metastatic recurrences after curative hepatic resections are very common. Tang et al have reported that recurrence rate within 5 years of curative hepatic resection is 61.5% [1]. As curative hepatic resection has a high tendency for metastatic recurrence, therapeutic interventions such as transarterial embolization and antiangiogenesis have been tried to further improve prognosis of HCC patients. Therefore, establishing a dependable, sensitive, easy, and economical method to predict metastatic recurrence following curative hepatic resection is of clinical urgency.

  1. Treatment of nevoid basal cell carcinoma syndrome: a case report

    Science.gov (United States)

    2016-01-01

    Nevoid basal cell carcinoma syndrome (NBCCS), also known as Gorlin syndrome, is characterized by various embryological deformities and carcinoma formation. It is caused by PTCHI gene mutations and is autosomal dominantly inherited. Some of the main symptoms of NBCCS are multiple basal cell carcinomas, multiple keratocystic odontogenic tumors (KCOTs) of the mandible, hyperkeratosis of the palmar and plantar, skeletal deformity, calcification of the falx cerebri, and facial defomity. Recurrent KCOT is the main symptom of NBCCS and is present in approximately 90% of patients. In NBCCS, KCOTs typically occur in multiples. KCOTs can be detected in patients under the age of 10, and new and recurring cysts develop until approximately the age of 30. The postoperation recurrence rate is approximately 60%. This case report presents a 14-year-old female patient with a chief complaint of a cyst found in the maxilla and mandible. The patient was diagnosed with NBCCS, and following treatment of marsupialization and enucleation, the clinical results were satisfactory. PMID:27847737

    Full Text Available Tubulocystic renal cell carcinoma (TCRCC is a rare variant of renal cell carcinoma, which has distinct histology but there is some controversy about its association with papillary renal cell carcinoma (PRCC and cell of origin in literature. We report an 18-year-old girl with the rare TCRCC of kidney associated with PRCC with metastases to the para-aortic nodes. The patient presented with hematuria and a right renal mass with enlarged regional nodes for which a radical nephrectomy with retroperitoneal lymph node dissection was done. On gross examination, a solid cystic lesion involving the lower pole and middle pole of the kidney measuring 12x9x9 cm was seen along with an additional cystic lesion in upper pole of kidney. Microscopically the main tumor showed the typical histology of a tubulocystic carcinoma with multiple cysts filled with secretions lined by variably flattened epithelium with hobnailing of cells. The mass in the upper pole was a high-grade PRCC and the nodal metastases had morphology similar to this component. To conclude, at least a small but definite subset of TCRCC is associated with PRCC, and cases associated with PRCC do seem to have a higher propensity for nodal metastasis as in the case we report.

    Nevoid basal cell carcinoma syndrome, or basal cell nevus syndrome (Gorlin syndrome), is a rare autosomal dominantly inherited disorder that is characterized by development of basal cell carcinomas from a young age. Other distinguishing clinical features are seen in a majority of patients, and include keratocystic odontogenic tumors (formerly odontogenic keratocysts) as well as dyskeratotic palmar and plantar pitting. A range of skeletal and other developmental abnormalities are also often seen. The disorder is caused by defects in hedgehog signaling which result in constitutive pathway activity and tumor cell proliferation. As sporadic basal cell carcinomas also commonly harbor hedgehog pathway aberrations, therapeutic agents targeting key signaling constituents have been developed and tested against advanced sporadically occurring tumors or syndromic disease, leading in 2013 to FDA approval of the first hedgehog pathway-targeted small molecule, vismodegib. The elucidation of the molecular pathogenesis of nevoid basal cell carcinoma syndrome has resulted in further understanding of the most common human malignancy.

    Laryngeal squamous cell carcinoma constitutes the most frequent carcinoma found in the head and neck region. A precise prediction for recurrence potential cannot be done on site, treatment and histologic grading. Since Proliferating Cell Nuclear Antigen (PCNA) and DNA-cytometry have shown a good correlation between premalignant lesions and their progressive potential towards full-fledged carcinoma in the larynx as described in part I of this work, we have analyzed the PCNA index and DNA cytometry in specimen taken from vocal chord carcinomas with a 5-year follow-up, in order to assess its relationship with the presence or absence of tumour progression. 42 cases with (21) and without (2) recurrence have been examined. The DNA-index ranged from 1.01 to 1.43 (mean 1.10) in the group without and from 1.02 to 1.59 (mean 1.38) in the group with recurrent carcinoma (p = 0.002). The PCNA-index ranged from 0.00% to 18.90% (mean 6.97%) in the nonrecurrent group and from 0.00 to 3g.50% (mean 16.35%) in the patients with recurrence (p = 0.001). Both indices also correlated in a highly significant way. From these data emerges a highly significant correlation between the cytometric indices of cell proliferation and PCNA immunostaining. Furthermore the high correction between PCNA and DNA-index is of special interest for single case assessment. High DNA aberration and PCNA-index in vocal chord carcinoma may indicate a higher cellular aggressiveness of the tumour, resulting in a greater overall risk of metastases and local recurrences. Our results support the thesis that the indices of cellular proliferation within some cancers can define subsets of patients of high risk and help in isolating a population in which a more aggressive clinical protocol may be proposed.

    Full Text Available "nBackground: Local recurrence in Nasopharyngeal Carcinoma (NPC presents is a major challenge. Patients experience substantial morbidity as well as poor survival if no further treatment is offered. Residual or recurrent nasopharyngeal carcinoma is usually managed by chemotherapy, stereotactic radiosurgery, external beam radiation therapy (EBRT, interstitial, and intracavitary brachytherapy or salvage surgery. This case presents the treatment of two consecutive localized recurrences of NPC."n "nCase presentation: The patient was a 59-year-old man who underwent a course of radical external-beam radiotherapy for a primary NPC in 1999, then another course of external radiation in 2004 for his first recurrence, and finally a course of brachytherapy for the second recurrence in 2005. The patient is well now in 2010, with no signs of disease five years after the third radiotherapy."n "nConclusion: Our experience of re-irradiation for this twice recurrent nasopharyngeal carcinoma has been promising with encouraging tumor control and acceptable treatment-related toxicity profile. This case indicates the efficacy of definitive re-irradiation for regional recurrence and the necessity for long-term observation for the salvageable early-stage local failure.

    Merkel cell carcinoma is an uncommon and aggressive primary cutaneous neuroendocrine carcinoma with a high rate of recurrence and metastasis. Optimal management is controversial; consequently, it is imperative to identify the signaling pathways involved in the pathogenesis of Merkel cell carcinoma so that effective therapeutic targeting agents can be developed. We previously reported that K homology domain-containing protein overexpressed in cancer is expressed in high-grade neuroendocrine carcinomas of the lung and extrapulmonary small cell carcinomas. The K homology domain-containing protein overexpressed in cancer (KOC), also known as L523S and IMP-3, is an insulin-like growth factor II messenger RNA-binding protein that promotes tumor cell proliferation by enhancing insulin-like growth factor II protein expression. Expression of KOC in Merkel cell carcinoma has not been investigated. We studied 20 Merkel cell carcinomas by immunohistochemistry using a monoclonal antibody against L523S/KOC. Of 20 Merkel cell carcinomas, 18 (90%) overexpressed KOC, with 11 (55%) overexpressing KOC in greater than 90% of tumor cells, 3 (15%) overexpressing KOC in 50% to 90% of tumor cells, 3 (15%) overexpressing KOC in 10% to 50% of tumor cells, and 1 (5%) overexpressing KOC in less than 10% of tumor cells. The immunostaining intensity was variable, with moderate to strong staining in 14 cases and weak staining in the remaining 4. Extent of expression of K homology domain-containing protein overexpressed in cancer predicted metastasis (P = .04) and was weakly correlated with increased tumor size (P = .08). In conclusion, Merkel cell carcinoma expresses K homology domain-containing protein overexpressed in cancer with an expression pattern similar to high-grade neuroendocrine carcinomas of the lung and extrapulmonary small cell carcinomas. We propose K homology domain-containing protein overexpressed in cancer as a potential target molecule for the treatment of high

    Ameloblastic Carcinoma (AC) is uncommon malignant epithelial odontogenic tumour of jaw, with characteristic histologic features and behavior. Clinically, it has aggressive, infiltrative growth pattern with a distinct predilection for mandible. It exhibits histologic features of ameloblastoma and gets dedifferentiated overtime to culminate in carcinoma. Majority of the cases arise denovo (primary) and only few cases arise from a pre-existing ameloblastoma (secondary). Spindle-cell differentiation in ameloblastic carcinoma is rare; Salter described it as a separate entity “low-grade spindle cell ameloblastic carcinoma. Here we report a case of 32-year-old female patient who presented with a swelling present for past six months. It was diagnosed as Spindle cell Ameloblastic Carcinoma (SpAC), after the hemimandibulectomy the patient was under regular follow up for 14 months, no sign of recurrence was seen. PMID:28274070

    2014-01-01

    Full Text Available Mixed adenoneuroendocrine carcinomas, spindle cell carcinomas, and clear cell carcinomas are all rare tumors in the biliary tract. We present the first case, to our knowledge, of an extrahepatic bile duct carcinoma composed of all three types. A 65-year-old man with prior cholecystectomy presented with painless jaundice, vomiting, and weight loss. CA19-9 and alpha-fetoprotein (AFP were elevated. Cholangioscopy revealed a friable mass extending from the middle of the common bile duct to the common hepatic duct. A bile duct excision was performed. Gross examination revealed a 3.6 cm intraluminal polypoid tumor. Microscopically, the tumor had foci of conventional adenocarcinoma (CK7-positive and CA19-9-postive surrounded by malignant-appearing spindle cells that were positive for cytokeratins and vimentin. Additionally, there were separate areas of large cell neuroendocrine carcinoma (LCNEC. Foci of clear cell carcinoma merged into both the LCNEC and the adenocarcinoma. Tumor invaded through the bile duct wall with extensive perineural and vascular invasion. Circumferential margins were positive. The patient’s poor performance status precluded adjuvant therapy and he died with recurrent and metastatic disease 5 months after surgery. This is consistent with the reported poor survival rates of biliary mixed adenoneuroendocrine carcinomas.

    Full Text Available Abstract Background Most treatment failure of buccal mucosal cancer post surgery is locoregional recurrence. We tried to figure out how close the surgical margin being unsafe and needed further adjuvant treatment. Methods Between August 2000 and June 2008, a total of 110 patients with buccal mucosa carcinoma (25 with stage I, 31 with stage II, 11 with stage III, and 43 with Stage IV classified according to the American Joint Committee on Cancer 6th edition were treated with surgery alone (n = 32, surgery plus postoperative radiotherapy (n = 38 or surgery plus adjuvant concurrent chemoradiotherapy (n = 40. Main outcome measures: The primary endpoint was locoregional disease control. Results The median follow-up time at analysis was 25 months (range, 4-104 months. The 3-year locoregional control rates were significantly different when a 3-mm surgical margin (≤3 versus >3 mm, 71% versus 95%, p = 0.04 but not a 5-mm margin (75% versus 92%, p = 0.22 was used as the cut-off level. We also found a quantitative correlation between surgical margin and locoregional failure (hazard ratio, 2.16; 95% confidence interval, 1.14 - 4.11; p = 0.019. Multivariate analysis identified pN classification and surgical margin as independent factors affecting disease-free survival and locoregional control. Conclusions Narrow surgical margin ≤3 mm, but not 5 mm, is associated with high risk for locoregional recurrence of buccal mucosa carcinoma. More aggressive treatment after surgery is suggested.

    AIM: To evaluate a series of patients with hepatocellular carcinoma (HCC) treated with several different protocols and devices.METHODS: We treated 138 patients [chronic hepatitis/liver cirrhosis (Child-Pugh A/B/C), 3/135 (107/25/3)]with two different devices and protocols: cool-tip needle [initial ablation at 60 W (standard method) (n=37)or at 40 W (modified method) (n = 28)] or; ablation with a LeVeen needle using a standard single-step, full expansion (single-step) method (n = 39) or a multi-step,incremental expansion (multi-step) method.RESULTS: Eleven patients experienced rapid and scattered recurrences 1 to 7 mo after the ablation. Nine patients were treated by the cool-tip original protocol (60 W) (9/37=24%) and the other two by the LeVeen single-step method (2/39=5%). The location of the recurrence was surrounding and limited to the site of ablation segment in three cases, and spread over one lobule or both lobules in the other eight cases. There was no recurrence in the patients treated with the modified cool-tip modified method (40 W) or the LeVeen multi-step method.CONCLUSION: There is a risk of rapid and scattered recurrence after RFA, especially when the standard cooltip procedure is used. Because such recurrence would worsen the prognosis, we recommend that modified protocols for the cool-tip and LeVeen needle methods should be used in clinical practice.

    2016-01-01

    Basal cell carcinoma (BCC) typically occurs in sun-exposed sites. Only 16 individuals with umbilical BCC have been described in the literature, and the characteristics of patients with umbilical BCC are summarized. PubMed was used to search the following terms: abdomen, basal cell carcinoma, basal cell nevus syndrome, and umbilicus. Papers with these terms and references cited within these papers were reviewed. BCC of the umbilicus has been reported in five men and 11 women; one man had two tumors. Two patients had basal cell nevus syndrome (BCNS). Other risk factors for BCC were absent. The tumor most commonly demonstrated nodular histology (64%, 9/14); superficial and fibroepithelioma of Pinkus variants were noted in three and two patients, respectively. The tumor was pigmented in eight individuals. Treatment was conventional surgical excision (87%, 13/15) or Mohs micrographic surgery (13%, 2/15); either adjuvant laser ablation or radiotherapy was performed in two patients. The prognosis after treatment was excellent with no recurrence or metastasis (100%, 16/16). In conclusion, BCC of the umbilicus is rare. It usually presents as a tumor with a non-aggressive histologic subtype in an individual with no risk factors for this malignancy. There has been no recurrence or metastasis following excision of the cancer. PMID:27738570

    Full Text Available Abstract Nevoid basal cell carcinoma syndrome (NBCCS, also known as Gorlin syndrome, is a hereditary condition characterized by a wide range of developmental abnormalities and a predisposition to neoplasms. The estimated prevalence varies from 1/57,000 to 1/256,000, with a male-to-female ratio of 1:1. Main clinical manifestations include multiple basal cell carcinomas (BCCs, odontogenic keratocysts of the jaws, hyperkeratosis of palms and soles, skeletal abnormalities, intracranial ectopic calcifications, and facial dysmorphism (macrocephaly, cleft lip/palate and severe eye anomalies. Intellectual deficit is present in up to 5% of cases. BCCs (varying clinically from flesh-colored papules to ulcerating plaques and in diameter from 1 to 10 mm are most commonly located on the face, back and chest. The number of BBCs varies from a few to several thousand. Recurrent jaw cysts occur in 90% of patients. Skeletal abnormalities (affecting the shape of the ribs, vertebral column bones, and the skull are frequent. Ocular, genitourinary and cardiovascular disorders may occur. About 5–10% of NBCCS patients develop the brain malignancy medulloblastoma, which may be a potential cause of early death. NBCCS is caused by mutations in the PTCH1 gene and is transmitted as an autosomal dominant trait with complete penetrance and variable expressivity. Clinical diagnosis relies on specific criteria. Gene mutation analysis confirms the diagnosis. Genetic counseling is mandatory. Antenatal diagnosis is feasible by means of ultrasound scans and analysis of DNA extracted from fetal cells (obtained by amniocentesis or chorionic villus sampling. Main differential diagnoses include Bazex syndrome, trichoepithelioma papulosum multiplex and Torre's syndrome (Muir-Torre's syndrome. Management requires a multidisciplinary approach. Keratocysts are treated by surgical removal. Surgery for BBCs is indicated when the number of lesions is limited; other treatments include laser

    Full Text Available Abstract Background Loco-regionally advanced nasopharyngeal carcinomas can be cured by the combination of chemotherapy and radiotherapy. In Eastern countries, plasma levels of viral Epstein-Barr deoxyribonucleic acid (DNA are accurate in predicting recurrence, but few data are available in Western populations. The aim of this prospective study was to evaluate the relationship between viral Epstein-Barr DNA copy numbers in plasma and the response rate, progression-free survival and overall survival in a cohort of Western patients with stage IIb-IVb nasopharyngeal cancer. Methods We evaluated plasma samples from 36 consecutive patients treated with induction chemotherapy followed by chemoradiation. EBV copy numbers were determined after DNA extraction using real-time quantitative polymerase chain reaction. Survival curves were estimated using the Kaplan–Meier method. Results Circulating Epstein-Barr virus DNA levels were measured before treatment, at the end of concomitant chemo- and radiotherapy, and during the follow-up period. Pre-treatment levels significantly correlated with the initial stage and probability of relapse. Their increase was 100% specific and 71.3% sensitive in detecting loco-regional or metastatic recurrence (an overall accuracy of 94.4%. Three-year progression-free and overall survival were respectively 78.2% and 97.1%. Conclusions The results of this study confirm that patients from a Western country affected by loco-regionally advanced nasopharyngeal carcinoma have high plasma Epstein-Barr virus DNA levels at diagnosis. The monitoring of plasma levels is sensitive and highly specific in detecting disease recurrence and metastases.

    A 59-year-old man developed an episode of syncope while he was driving. This resulted in a motor vehicle accident, and the patient sustained an open fracture of the left femur. Biopsy of the left femur fracture showed a metastastic renal cell carcinoma, and echocardiography revealed a right ventricular mass without contiguous vena caval or right atrial involvement. This is one of the few reported cases of renal cell carcinoma associated with syncope as an initial symptom.

    BRAF and KRAS mutations in ovarian serous borderline tumors (OSBTs) and ovarian low-grade serous carcinomas (LGSCs) have been previously described. However, whether those OSBTs would progress to LGSCs or those LGSCs were developed from OSBT precursors in previous studies is unknown. Therefore, we assessed KRAS and BRAF mutations in tumor samples from 23 recurrent LGSC patients with known initial diagnosis of OSBT. Paraffin blocks from both OSBT and LGSC samples were available for 5 patients, and either OSBT or LGSC were available for another 18 patients. Tumor cells from paraffin-embedded tissues were dissected out for mutation analysis by conventional polymerase chain reaction (PCR) and Sanger sequencing. Tumors that appeared to have wild-type KRAS by conventional PCR–Sanger sequencing were further analyzed by full COLD (coamplification at lower denaturation temperature)-PCR and deep sequencing. Full COLD-PCR was able to enrich the amplification of mutated alleles. Deep sequencing was performed with the Ion Torrent personal genome machine (PGM). By conventional PCR–Sanger sequencing, BRAF mutation was detected only in one patient and KRAS mutations were detected in 10 patients. Full COLD-PCR deep sequencing detected low-abundance KRAS mutations in eight additional patients. Three of the five patients with both OSBT and LGSC samples available had the same KRAS mutations detected in both OSBT and LGSC samples. The remaining two patients had only KRAS mutations detected in their LGSC samples. For patients with either OSBT or LGSC samples available, KRAS mutations were detected in 7 OSBT samples and 6 LGSC samples. To our surprise, patients with the KRAS G12V mutation appeared to have shorter survival times. In summary, KRAS mutations are very common in recurrent LGSC, while BRAF mutations are rare. The findings indicate that recurrent LGSC can arise from proliferation of OSBT tumor cells with or without detectable KRAS mutations. PMID:24549645

    Full Text Available Abstract Introduction Radiation-induced nonmelanoma skin cancer was first reported seven years after the discovery of X-rays, but has received relatively little consideration in the literature. Specifically, nonmelanoma skin cancer after conservative surgery and radiation for early stage breast cancer has not been well studied. We report the case of a woman who developed squamous cell carcinoma of the nipple nine years after conservative surgery and radiation for ductal carcinoma in situ of the ipsilateral breast. We also review the relevant literature available to date. Case presentation A 66-year-old African-American woman presented to the hospital with a non-healing ulcer of the right nipple. Her past medical history was significant for right breast ductal carcinoma in situ for which she had undergone lumpectomy and whole breast radiation therapy nine years previously. Mammography and magnetic resonance imaging studies were negative for recurrent breast cancer. However, the latter demonstrated abnormal enhancement in the nipple-areolar region. An incisional biopsy of the lesion demonstrated invasive squamous cell carcinoma. Subsequently, the patient underwent wide excision of the nipple-areolar complex. Sentinel lymph-node biopsy was offered but our patient declined. She was considered to have local disease and hence no further treatment was recommended. Conclusion This case represents the first reported occurrence of squamous cell carcinoma of the nipple to follow conservative surgery and radiation for ductal carcinoma in situ of the ipsilateral breast. It is likely that radiation overexposure resulted in a radiation burn and subsequent radiodermatitis, placing it at risk for squamous cell carcinoma. A diagnosis of squamous cell carcinoma should be considered in a patient with a nipple lesion following radiation therapy for breast cancer.

    Paget's disease of the bone, historically known as osteitis deformans, is an uncommon disease typically affecting individuals of European descent. Patients with Paget's disease of the bone are at increased risk for primary bone neoplasms, particularly osteosarcoma. Many cases of metastatic disease to pagetic bone have been reported. However, renal cell carcinoma metastasized to pagetic bone is extremely rare. A 94-year-old male presented to the emergency department complaining of abdominal pain. A computed tomography scan of the abdomen demonstrated a large mass in the right kidney compatible with renal cell carcinoma. The patient was also noted to have Paget's disease of the pelvic bones and sacrum. Within the pagetic bone of the sacrum, there was an enhancing mass compatible with renal cell carcinoma. A subsequent biopsy of the renal lesion confirmed renal cell carcinoma. Paget's disease of the bone places the patient at an increased risk for bone neoplasms. The most commonly reported sites for malignant transformation are the femur, pelvis, and humerus. In cases of malignant transformation, osteosarcoma is the most common diagnosis. Breast, lung, and prostate carcinomas are the most common to metastasize to pagetic bone. Renal cell carcinoma associated with Paget's disease of the bone is very rare, with only one prior reported case. Malignancy in Paget's disease of the bone is uncommon with metastatic disease to pagetic bone being extremely rare. We report a patient diagnosed with concomitant renal cell carcinoma and metastatic disease within Paget's disease of the sacrum. Further research is needed to assess the true incidence of renal cell carcinoma associated with pagetic bone.

  10. Clinical Significance of Langerhans Cells in Squamous Cell Carcinoma of the Larynx

    Full Text Available Langerhans cells (LCs may be involved in the immunosurveillance against tumors as antigen-presenting cells. Our objective has been to determine the relevance of LC in progression of larynx squamous cell carcinomas and their relationship with different subpopulations of tumor-infiltrating cells. LCs were investigated by immunohistochemical methods using anti-CD1 antibody. LCs were detected in most of the primary tumors studied (44 out of 50 and also in metastases (6 out of 10 and recurrences (2 out of 3, but we did not find any statistical association between number of LCs and clinical-pathological parameters or survival. However, the number of LCs was increased in patients with evident infiltration of lymphocytes, mainly cytotoxic T cells. We can conclude that although LCs did not show clinical utility as prognostic marker, they may play a role in releasing an active immune response in larynx carcinomas, according to their ability to present antigens to sensitized T cells.

    Full Text Available Follicular cell-derived well-differentiated thyroid cancer, papillary (PTC and follicular thyroid carcinomas (FTC compose 95% of all thyroid malignancies. Familial follicular cell-derived well-differentiated thyroid cancers contribute to 5% of those cases. These familial follicular cell derived carcinomas or non-medullary thyroid carcinomas (NMTC divide into two clinical-pathological groups. One group, syndromic-associated, composed by predominately non-thyroidal tumors, is comprised of Pendred syndrome, Warner syndrome, Carney complex type 1, PTEN-hamartoma tumor syndrome (Cowden disease; PHTS, familial adenomatous polyposis (FAP/Gardner syndrome. Additionally other less established links correlated to the development of follicular cell-derived tumors have also included Ataxia-teleangiectasia syndrome, McCune Albright syndrome, and Peutz-Jeghers syndrome. The subsequent group encompasses syndromes typified by non-medullary thyroid carcinomas or NMTC, as well as, pure familial (f PTC with or without oxyphilia, fPTC with multinodular goiter and fPTC with papillary renal cell carcinoma. This heterogeneous group of diseases has not a established genotype-phenotype correlation as the well-known genetic events identified in the familial C-cell-derived tumors or medullary thyroid carcinomas (MTC. Clinicians should be have the knowledge to identify the likelihood of a patient presenting with thyroid cancer having an additional underlying familial syndrome stemming from characteristics through morphological findings that would alert the pathologist to have the patient undergo subsequent molecular genetics evaluations. This review will discuss the clinical and pathological findings of the patients with familial papillary thyroid carcinoma, such as familial adenomatous polyposis, Carney complex, Werner syndrome, and Pendred syndrome and the heterogeneous group of familial papillary thyroid carcinoma.

    2016-11-01

    Full Text Available A 73-year-old male underwent transurethral resection of a bladder tumor in August 2010 and April 2011. Pathological examination revealed urothelial carcinoma. After the surgery, chemotherapy and intravesical Bacillus Calmette-Guerin instillation were performed. In September 2014, he once again underwent transurethral resection of the bladder tumor for recurrence, and was again diagnosed with urothelial carcinoma, pT2, by pathological examination. After neoadjuvant chemotherapy, radical cystectomy for tumor recurrence was performed. Pathological examination at this time revealed small cell carcinoma, pT3N0. It is rare for urothelial carcinoma to change to small cell carcinoma, and the mechanism and cause of this change are still unknown. In this case report, we discuss what causes small cell carcinoma of the urinary bladder and review the literature regarding its origin.

    Full Text Available Basal cell carcinoma (BCC is the most common malignant tumor of skin. The most common site (80% is head and neck. BCC exhibits a varied morphology such as adenoid, keratotic, sebaceous, basosquamous, apocrine, eccrine or fibroepithelial. Tumors with a similar histopathological picture are cutaneous adenoid cystic carcinoma and primary cutaneous cribriform apocrine carcinoma. Immunohistochemistry, along with clinical findings, acts as an adjunct in reaching an accurate diagnosis. Here, we present an interesting case of adenoid BCC in a 55-year-old man.

    Full Text Available CONTEXT: The pancreas is an unusual site for metastases of renal cell carcinoma origin, sometimes occurring many years after nephrectomy. We herein present two cases of pancreatic metastases of renal cell carcinoma which occurred 17 and 19 years after the primary diagnosis. CASE REPORT: In the first case, metastases were found in the head of the pancreas, upper right arm and the right lobe of the thyroid gland. In the second case, a tumor was found in the tail of the pancreas and a remnant of the right kidney. This was the third recurrence of the original tumor after an initial left nephrectomy and two subsequent partial right nephrectomies in the past. Treatment in the first case consisted of excision of the tumor in the upper right arm, a Whipple operation, and a thyroidectomy. In the second case, a distal pancreatectomy and remnant right nephrectomy were undertaken. Both patients recovered from the operations without complications and remain free of tumor in follow-up periods of 54 and 8 months respectively. CONCLUSIONS: Resection of renal cell carcinoma metastases involving the pancreas provides satisfactory long-term survival, and should be undertaken whenever possible.

    Full Text Available Objective: To determine and compare the mast cell count in primary and recurrent vascularized pterygium, and in normal bulbar conjunctiva. Methods: The study included 22 patients with primary pterygium (PP group and 28 patients with vascularized recurrent pterygium (VRP group that underwent excision via the limbal conjunctival autograft technique. Normal conjunctiva samples were collected from the superotemporal bulbar conjunctival region, just temporal to the site from which the autograft conjunctival tissue was harvested. The total number of mast cells in the pterygium (primary and recurrent and control tissue samples was calculated microscopically using 1% toluidine blue stain under 400× magnification. Results: The mean mast cell count in primary and vascularized recurrent pterygium tissue was 7.45 ± 2.06 mm–2 and 16.11 ± 4.33 mm–2, respectively, and the difference was significant (independent samples t-test, P<0.001. The mean mast cell count in pterygium tissue was significantly higher than that in normal conjunctiva tissue in both groups (Student's t-test, P<0.001. Conclusion: An increase in the number of mast cells might play a role in the pathogenesis of recurrent pterygium. Determination of a mast cell count cut-off value could be of diagnostic significance for recurrent pterygium.

    PURPOSE: The aim of this study was to investigate symptoms of depression and anxiety in the patients with oral squamous cell carcinoma (OSCC). METHODS: 76 patients with oral squamous cell carcinoma participated in this program. All patients were rated with the self-rating anxiety scale (SAS) and the self-rating depression scale (SDS). The mean scores of SAS and SDS were compared to those scores of the Norm of Chinese people. In addition, the different treatment results of the patients with different levels of anxiety and depression were studied. Further, the number of patients of SAS, SDS with more than 50 score were compared between primary cancer patients and recurrent cancer patients. RESULTS: The scores of SAS, SDS and the number of patients with more than 50 score in the patients group were obviously higher than those in Chinese Norm (P<0.01).The levels of anxiety and depression in 32 patients with recurrent cancer were more severe than those of 44 patients with primary cancer. The patients with anxiety and/or depression showed poor prognosis. CONCLUSION: Anxiety and depression are common symptoms in patients with OSCC and have negative effects on the prognosis, thus the psychological intervention for the patients must be carried out.

    Full Text Available Primary pancreatic small cell carcinoma (SCC is rare, with just over 30 cases reported in the literature. Only 7 of these patients underwent surgical resection with a median survival of 6 months. Prognosis of SCC is therefore considered to be poor, and the role of adjuvant therapy is uncertain. Here we report two institutions’ experience with resectable pancreatic SCC. Six patients with pancreatic SCC treated at the Johns Hopkins Hospital (4 patients and the Mayo Clinic (2 patients were identified from prospectively collected pancreatic cancer databases and re-reviewed by pathology. All six patients underwent a pancreaticoduodenectomy. Clinicopathologic data were analyzed, and the literature on pancreatic SCC was reviewed. Median age at diagnosis was 50 years (range 27-60. All six tumors arose in the head of the pancreas. Median tumor size was 3 cm, and all cases had positive lymph nodes except for one patient who only had five nodes sampled. There were no perioperative deaths and three patients had at least one postoperative complication. All six patients received adjuvant therapy, five of whom were given combined modality treatment with radiation, cisplatin, and etoposide. Median survival was 20 months with a range of 9-173 months. The patient who lived for 9 months received chemotherapy only, while the patient who lived for 173 months was given chemoradiation with cisplatin and etoposide and represents the longest reported survival time from pancreatic SCC to date. Pancreatic SCC is an extremely rare form of cancer with a poor prognosis. Patients in this surgical series showed favorable survival rates when compared to prior reports of both resected and unresectable SCC. Cisplatin and etoposide appears to be the preferred chemotherapy regimen, although its efficacy remains uncertain, as does the role of combined modality treatment with radiation.

    BACKGROUND: Four tumor markers for hepatocellular car-cinoma (HCC), alpha-fetoprotein (AFP), glypican-3 (GPC3), vascular endothelial growth factor (VEGF) and des-gamma-carboxy prothrombin (DCP), are closely associated with tumor invasion and patient’s survival. This study estimated the predict-ability of preoperative tumor marker levels along with patho-logical parameters on HCC recurrence after hepatectomy. METHODS: A total of 140 patients with HCC who underwent hepatectomy between January 2012 and August 2012 were enrolled. The demographics, clinical and follow-up data were collected and analyzed. The patients were divided into two groups: patients with macroscopic vascular invasion (MaVI +) and those without MaVI (MaVI-). The predictive value of tumor markers and clinical parameters were evaluated by uni-variate and multivariate analysis. RESULTS: In all patients, tumor size (>8 cm) and MaVI were closely related to HCC recurrence after hepatectomy. For MaVI+ patients, VEGF (>900 pg/mL) was a signiifcant predic-tor for recurrence (RR=2.421; 95% CI: 1.272-4.606;P=0.007). The 1- and 2-year tumor-free survival rates for MaVI+ pa-tients with VEGF≤900 pg/mL versus for those with VEGF>900 pg/mL were 51.5% and 17.6% versus 19.0% and 4.8%(P445 mAu/mL and tumor size >8 cm were two independent risk factors for tumor recur-rence (RR=2.307, 95% CI: 1.132-4.703,P=0.021; RR=3.150, 95% CI: 1.392-7.127,P=0.006; respectively). The 1- and 2-year tumor-free survival rates for the patients with DCP≤445 mAu/mL and those with DCP >445 mAu/mL were 90.4% and 70.7% versus 73.2% and 50.5% respectively (P=0.048). The 1-and 2-year tumor-free survival rates for the patients with tu-mor size≤8 cm and >8 cm were 83.2% and 62.1% versus 50.0%and 30.0%, respectively (P=0.003). CONCLUSIONS: The MaVI+ patients with VEGF≤900 pg/mL had a relatively high tumor-free survival than those with VEGF >900 pg/mL. In the MaVI- patients, DCP >445 mAu/mL and tumor size >8 cm were predictive factors

  7. Liver transplantation for hepatocellular carcinoma on cirrhosis: Strategies to avoid tumor recurrence

    Hepatocellular carcinoma (HCC) is one of the most frequent neoplasms worldwide and in most cases it is associated with chronic liver disease. Liver trans-plantation (LT) is potentially the optimal treatment for those patients with HCC who have a poor functional hepatic reserve due to their underlying chronic liver disease. However, due to the limited availability of donors, only those patients whose oncologic profile is favorable can be considered for LT. Despite the care-ful selection of candidates based on strict rules, 10 to 20% of liver transplant recipients who have HCC in the native cirrhotic liver develop tumor recurrence after transplantation. The selection criteria pres-ently employed to minimize the risk of recurrence are based on gross tumor characteristics defined by imaging techniques; unfortunately, the accuracy of imaging is far from being optimal. Furthermore, mi-croscopic tumor features that are strictly linked with prognosis can not be assessed prior to transplanta-tion. Pre-transplantation tumor downstaging may allow transplantation in patients initially outside the selection criteria and seems to improve the progno-sis; it also provides information on tumor biology. The main peculiarity of the transplantation setting, when this is compared with other modalities of treatment, is the need for pharmacological immunosuppression: this is based on drugs that have been demonstrated to increase the risk of tumor development. As HCC is an aggressive malignancy, immunosuppression has to be handled carefully in patients who have HCC at the time of transplantation and new categories of immu-nosuppressive agents should be considered. Adjuvant chemotherapy following transplantation has failed to show any significant advantage. The aim of the pres-ent study is to review the possible strategies to avoid recurrence of HCC after liver transplantation based on the current clinical evidence and the more recent de-velopments and to discuss possible future directions.

    Detection of recurrence of medullary thyroid carcinoma (MTC) remains a diagnostic problem. Increased serum tumour marker levels frequently indicate recurrence while conventional imaging techniques (CIT) are non-diagnostic. In this study, we performed indium-111 octreotide scintigraphy and CIT in a series of 20 patients with MTC presenting with elevated serum tumour markers after surgery. {sup 111}In-octreotide whole-body studies detected 15 pathological uptake foci in 11 of the 20 patients studied and CIT detected 17 lesions in 11 of the 20 patients. Ten patients underwent reoperation, five of them with positive {sup 111}In-octreotide scintigraphy and CIT and two with positive isotopic exploration and negative CIT. Surgical findings demonstrated that the results of isotopic study and CIT had been false-positive for MTC in one case (sarcoidosis). The six patients with true-positive {sup 111}In-octreotide studies had significantly higher basal calcitonin (CT) and carcinoembryonic antigen (CEA) levels than the patients with negative isotopic studies. The expression of somatostatin receptor (SSTR) subtypes by PC-PCR could be investigated in four cases with a positive isotopic study. Among the three cases with a true-positive study, SSTR2, the SSTR subtype that preferentially binds to the somatostatin analogue octreotide, was detected in two, SSTR5 was demonstrated in the three, and SSTR3 was detected in one. No subtype of SSTR was detected in the case with a final diagnosis of sarcoidosis. We conclude that {sup 111}In-octreotide has limited sensitivity in detecting recurrence in patients with MTC, although its sensitivity may improve with high serum CT levels. This radionuclide imaging technique should be employed when conventional imaging techniques are negative or inconclusive or when the presence of somatostatin receptors may provide the basis for treatment with somatostatin analogues.

    Gallbladder small cell carcinoma (SCC) comprises only 0.5 % of all gallbladder cancer and consists of aggressive tumors with poor survival outcomes against current treatments. These tumors are most common in elderly females, particularly those with cholecystolithiasis. We report the case of a 79-year-old woman with gallbladder small cell carcinoma. The patient had intermittent right upper quadrant abdominal pain and was admitted to our hospital due to suspected acute cholecystitis. She regularly received medical treatment for diabetes, hypertension, and dyslipidemia. On initial laboratory evaluation, the levels of aspartate aminotransferase (AST), total bilirubin, and C-reactive protein (CRP) were markedly elevated. She underwent computed tomography (CT) for screening. CT images showed a thick-walled gallbladder containing multiple stones and multiple 3-cm-sized round nodular lesions, which were suggestive of metastatic lymph nodes. After percutaneous transhepatic gallbladder drainage was performed, endoscopic ultrasound-guided fine needle aspiration of enlarged lymph nodes resulted in a diagnosis of small cell carcinoma or adenocarcinoma. However, we could not identify the primary lesion before the surgery because of no decisive factors. We performed cholecystectomy because there was a possibility of cholecystitis recurrence risk and also partial liver resection because we suspected tumor invasion. The final pathological diagnosis was neuroendocrine carcinoma of the gallbladder, small cell type. The tumor stage was IVb, T3aN1M1. The patient died 13 weeks after the surgery. In the present paper, we review the current available English-language literature of gallbladder SCC.

    Full Text Available O carcinoma basocelular é a neoplasia maligna mais comum em humanos e sua incidência vem aumentando nas últimas décadas. Sua grande frequência gera significativo ônus ao sistema de saúde, configurando problema de saúde pública. Apesar das baixas taxas de mortalidade e de rara ocorrência de metástases, o tumor pode apresentar comportamento invasivo local e recidivas após o tratamento, provocando importante morbidade. Exposição à radiação ultravioleta representa o principal fator de risco ambiental associado a sua gênese. Entretanto, descrevem-se outros elementos de risco: fotótipos claros, idade avançada, história familiar de carcinomas de pele, olhos e cabelos claros, sardas na infância e imunossupressão, além de aspectos comportamentais, como exercício profissional exposto ao sol, atividade rural e queimaduras solares na juventude. Entre 30% e 75% dos casos esporádicos estão associados à mutação do gene patched hedgehog, mas outras alterações genéticas são ainda descritas. A neoplasia é comumente encontrada concomitantemente com lesões cutâneas relacionadas à exposição solar crônica, tais como: queratoses actínicas, lentigos solares e telangiectasias faciais. A prevenção do carcinoma basocelular se baseia no conhecimento de fatores de risco, no diagnóstico e tratamento precoces e na adoção de medidas específicas, principalmente, nas populações susceptíveis. Os autores apresentam uma revisão da epidemiologia do carcinoma basocelular.Basal cell carcinoma is the most common malignant neoplasm in humans and its incidence has increased over the last decades.

    A 49 year-old patient with the complaint of a mass located in the caesarean scar was admitted. There was a fixed mass 30í30 mm in diameter with regular contour located at the right corner of the pfannenstiel incision. Computed tomography revealed a (40í50í50) mm solid mass lesion with margins that cannot be distinguished from the uterus, bladder and small intestines and a heterogeneous mass lesion (50í45í55) mm in diameter, located in the right side of the anterior abdominal wall. Cytoreductive surgery including total abdominal hysterectomy and bilateral salpingo-oophorectomy was performed. Final pathology was clear cell carcinoma. Clear cell carcinoma arising from an extraovarian endometriotic focus was diagnosed and the patient received 6 cycles paclitaxel-carboplatin chemotherapy as adjuvant treatment. The patient who was lost to follow-up applied to our clinic 2 years after surgery with a recurrent mass in the left inguinal region. After 3 cycles of chemotherapy, the patient's tumoral mass in the left inguinal region was excised. The result of the pathology was carcinoma metastasis. It is decided that the following treatment of the patient should be palliative radiation therapy. The patient who underwent palliative radiation therapy died of disease after 4 months of the second operation.

    In this study, in vitro chemosensitivity testing was conducted on primary cultured breast cancer cells from 96 patients with breast cancer, and the results showed that the cells from a few patients with primary breast cancer developed multidrug resistance (MDR) prior to the first chemotherapy exposure. All the cells from the recurrent cancer patients had MDR. The findings suggested that patients having MDR would benefit from high-dose chemotherapy (HDC) regimens. In vitro chemosensitivity screening, which was aimed at improving the therapeutic efficacy and minimizing side effects, helps in choosing individualized treatment for breast cancer.

    Reported are the results of soft X-ray therapy of 237 patients with 245 basal cell carcinomas of the eye lids. The medial angle of the eye and the lower eye lid were mostly affected. Histologically in 62% solid basal cell carcinomas and in 14% sclerodermiform basal cell carcinomas could be diagnostized. By soft X-ray therapy 92% of all basal cell carcinomas could be healed. All recurrences were observed in the first 2 years following radiotherapy. They were relatively more frequent at the lateral angle of the eye. Recurrences occured in 4.9% of female patients, and in 13.0% of male patients. In two thirds they may be due to elected conditions of radiotherapy; in one third the cause of recurrences are not known. The cosmetic result was good or excellent in 95% of patients during the first 2 years following radiotherapy. After more than 5 years this rate declined to 65%. A good functional result could be obtained in 88% of the patients.

    Aim: To select and analyze the most representative papers published in the literature concerning oral squamous cell carcinoma (OSCC), specifically dealing with salvage surgery following primary treatment by surgery with or without by postoperative radiotherapy, specifically focusing in the oral cavity and oropharynx locations.Methods: A bibliography search on MEDLINE and EMBASE databases for studies published from March 2000 to March 2016 was conducted. The authors only included studies published in the English language and those dealing with “squamous cell carcinoma of the oral cavity and/or oropharynx”. The following technical bibliographic exclusion criteria were applied: (1) case reports; (2) technical report; (3) animal orin vitro studies; (4) review articles; (5) uncontrolled clinical studies; and (6) publications in which the same data were published by the same group of researchers. The abstracts of yielded results were reviewed and the full text of those with apparent relevance was obtained.Results: A total amount of 188 studies were found using the above reported searching parameters. Thirteen original papers were finally selected according to the inclusion and exclusion criteria. From 1,692 analyzed patients, overall recurrence rate was 26% (range: 15-41.7%), with a mean 47.3%, 35.1% and 10.9% local, regional and loco-regional recurrence, respectively. Mean 5-year overall survival rate was 40.2% (range: 37.5-42.9%).Conclusion:Salvage surgery is the best option for the treatment of recurrent OSCC, either local, regional or loco-regional, with the highest rates in terms of survival and with an acceptable morbidity.

    Ovarian tumors have a low incidence in childhood, accounting for 1% of malignancies within the ages of 0-17 years. Small cell carcinoma of the ovary is a rare histology and historically has a poor prognosis. We report a case of an 11-year-old female diagnosed with small cell carcinoma of the ovary and hypercalcemia (SCCOHT). There was a strong family history of the disease, a reduction in the age of onset in the proband, and the absence of BRCA mutations. This case suggests the phenomenon of genetic anticipation in an ovarian cancer.

    Full Text Available Xin Li, Zhiyu Han, Zhigang Cheng, Jie Yu, Xiaoling Yu, Ping Liang Department of Interventional Ultrasound, Chinese PLA General Hospital, Beijing, People's Republic of China Purpose: To investigate the prognostic value of preoperative absolute lymphocyte count (ALC in recurrent hepatocellular carcinoma (RHCC following thermal ablation. Materials and methods: We retrospectively analyzed the relationship between preoperative ALC and the clinicopathologic factors and long-term prognosis in 423 RHCC patients who underwent curative thermal ablation. Correlation analysis, receiver operating characteristic (ROC calculation, Kaplan–Meier curves, and multivariate regression were used for statistical analysis. Results: The median time to recurrence was 12 months for RHCC patients after thermal ablation. On multivariate Cox regression analysis, preoperative ALC was an independent risk factor for cancer recurrence, along with tumor differentiation and α-fetoprotein level. ALC ≥1.64×109/L defined by ROC calculation was associated with prolonged survival (area under the curve 0.741, P<0.001. Patients with ALC ≥1.64×109/L showed a mean survival of 20.2 months versus 11.6 months for patients with ALC <1.64×109/L (P<0.001. Patients were stratified into high and low groups according to ALC status. After excluding the basic parameters between groups, the 1- and 3-year recurrence rates in the high group were 20.9% and 29.5%, respectively, which were significantly lower than those of the low group (58.4% and 71.9%, respectively; P<0.001. The recurrence-free survival rates in the two groups analyzed by Kaplan–Meier curves were significantly different (P<0.001. Conclusion: Preoperative ALC is a powerful prognostic factor for RHCC recurrence after thermal ablation, which suggests that maintaining a high ALC in RHCC patients might improve cancer outcomes. Keywords: absolute lymphocyte count, recurrent hepatocellular carcinoma, thermal ablation, recurrence

Methods Forty-five women with EOC were treated with IOERT. Twenty-five patients had primary disease (PD without distant metastasis at IOERT, and 20 patients had an isolated local recurrence (ILR after surgery. All 45 patients in this series underwent optimal cytoreductive (≤ 1 cm surgery. The whole pelvic (WP radiotherapy was intraoperatively delivered using 12 Mev electron beam; 43 patients received 18-20 Gy and two patients received 10 Gy. Thirty-three patients received postoperateive intraperitoneal (IP chemotherapy, while seven patients received intravenous (IV chemotherapy. Five patients refused concurrent chemotherapy. Overall survival (OS rates were analyzed using the Kaplan-Meier method. Results Tumor recurrence and metastasis were observed in 16 patients (35.6%. Of those, 14 patients (31.1% relapsed and two patients (4.4% had distant metastasis alone. Eight of 25 (32% local failures were observed in the PD group, as compared to 6/20 (30% in the ILR group (P = 0.885. Actuarial local control at five year follow-up was 31/45 (68.9%.

    We present a cohort of 8 renal carcinomas that displayed a variable (5%-95% extent) light microscopic appearance of renal angiomyoadenomatous tumor/clear cell papillary renal cell carcinoma (RAT/CCPRCC) without fulfilling the criteria for these tumors. All but 1 case predominantly (75%-95% extent) showed histopathologic features of conventional clear cell renal cell carcinoma. In 5 of 7 cases with mostly conventional clear renal cell carcinoma (CRCC) morphology, a diagnosis of CRCC was supported by the molecular genetic findings (presence of von Hippel-Lindau tumor suppressor [VHL] mutation and/or VHL promoter methylation and/or loss of heterozygosity [LOH] for 3p). Of the other 2 cases with predominantly characteristic CRCC morphology, 1 tumor did not reveal any VHL mutation, VHL promoter methylation, or LOH for 3p, and both chromosomes 7 and 17 were disomic, whereas the other tumor displayed polysomy for chromosomes 7 and 17 and no VHL mutation, VHL promoter methylation, or LOH for 3p. One tumor was composed primarily (95%) of distinctly RAT/CCPRCC-like morphology, and this tumor harbored a VHL mutation and displayed polysomy for chromosomes 7 and 17. Of the 5 cases with both histomorphologic features and molecular genetic findings of CRCC, we detected significant immunoreactivity for α-methylacyl-CoA racemase in 2 cases and strong diffuse immunopositivity for cytokeratin 7 in 3 cases. Despite the combination of positivity for α-methylacyl-CoA racemase and cytokeratin 7 in 2 cases, there was nothing to suggest of the possibility of a conventional papillary renal cell carcinoma with a predominance of clear cells.

    Syringoid carcinoma (syringoid eccrine carcinoma, or eccrine epithelioma) is a rare cutaneous tumor with some controversy regarding its correct definition. This tumor shows a slow growth and has often been for many years, some decades before diagnosis. It may also be difficult to differentiate from its benign counterpart (syringoma) or other adnexal carcinoma and cutaneous metastasis. There have been limited case reports of syringoid carcinoma in foreign literatures but none from Iran. Here we report a case of syringoid carcinoma in a 52 year-old Iranian man. Syringoid eccrine carcinoma is a very rare and uncommon diagnosed tumor thought to be derived from eccrine sweat apparatus. It locally invasive, destructive and often shows recurrence. It may also be difficult to differentiate from metastatic adenocarcinoma.

    A 32-year-old female American flamingo (Phoenicopterus ruber) was presented with a squamous cell carcinoma of the middle digit of the right foot. No clinical, hematologic, or radiologic evidence of metastasis was present. Salvage amputation of the digit resulted in complete cure, whereas previous electrosurgery and radiation therapy were unsuccessful. Three years later, another squamous cell carcinoma was diagnosed in the middle digit of the left foot. The digit was also amputated. Seven months after the second amputation, the bird did not have any recurrence or signs of metastasis.

    Breast metastases from extramammary neoplasms are very rare. We presented a 66 year-old female with metastasis of small cell lung carcinoma to the breast. She presented with consolidation over the left upper lobe of her lung undetermined after endobronchial or video-assisted thoracoscopic surgery (VATS) biopsy, and this was treated effectively after antibiotic therapy at initial stage. The left breast lumps were noted 4 months later, and she underwent a modified radical mastectomy under the impression of primary breast carcinoma. However, the subsequent chest imaging revealed re-growing mass over the left mediastinum and hilum, and cells with the same morphological and staining features were found from specimens of transbronchial brushing and biopsy. An accurate diagnosis to distinguish a primary breast carcinoma from metastatic one is very important because the therapeutic planning and the outcome between them are different.

    Epidermal growth factor (EGF) gene single-nucleotide polymorphism (SNP) is associated with an increased risk of hepatic tumors. The study aimed to elucidate the impact of EGF SNP and EGF receptor (EGFR) expression on the recurrence of hepatocellular carcinoma (HCC) after hepatectomy. To examine the impact of EGF SNP and EGFR on recurrent HCC, we retrospectively analyzed 141 HCC patients with chronic hepatitis C virus infection who underwent curative hepatectomy. The EGF *61 GG allele was present in 69 patients (48.9%), AG in 56 (39.7%) and AA in 16 (11.4%). The AA group had a significantly lower rate of intrahepatic metastasis (0% vs 16.5%, P = 0.02), lower serum EGF concentration (26.3 ± 15.9 pg/mL vs 43.4 ± 30.5 pg/mL, P = 0.02) and lower proportion of early recurrence (≤2 years; 28.6% vs 71.2%, P = 0.03) than the AG/GG group. The AA group had significantly higher recurrence-free survival than the AG/GG group (P = 0.04), but there was no significant difference in overall survival between these two groups (P = 0.97). High versus low EGFR expression analyzed by immunohistochemical staining in cancer cells was not significantly associated with overall survival (P = 0.37) or recurrence-free survival (P = 0.39). Therefore, EGF *61 AA was associated with a lower risk of recurrence after curative hepatectomy for HCC in patients with hepatitis C virus infection than other genotypes, but EGFR expression in cancer cells was not significantly associated with prognosis.

    The aim of our study was to determine the diagnostic value of a novel image analysis method called parametric response mapping (PRM) for prediction of intrahepatic recurrence of hepatocellular carcinoma (HCC) treated with conventional transcatheter arterial chemoembolization (TACE). This retrospective study was approved by the IRB. We recruited 55 HCC patients who achieved complete remission (CR) after TACE and received longitudinal multiphasic liver computed tomography (CT). The patients fell into two groups: the recurrent tumour group (n = 29) and the non-recurrent tumour group (n = 26). We applied the PRM analysis to see if this technique could distinguish between the two groups. The results of the PRM analysis were incorporated into a prediction algorithm. We retrospectively removed data from the last time point and attempted to predict the response to therapy of the removed data. The PRM analysis was able to distinguish between the non-recurrent and recurrent groups successfully. The prediction algorithm detected response to therapy with an area under the curve (AUC) of 0.76, while the manual approach had AUC 0.64. Adopting PRM analysis can potentially distinguish between recurrent and non-recurrent HCCs and allow for prediction of response to therapy after TACE. (orig.)

    Pretransplant alpha-fetoprotein (AFP) is a useful tumor marker predicting recurrence of hepatocellular carcinoma (HCC). Little is known, however, about the relationship between changes in AFP concentration and prognosis. This study investigated the clinical significance of change in peri-transplant AFP level as a predictor of HCC recurrence. Data from 125 HCC patients with elevated pretransplant AFP level who underwent liver transplantation (LT) between February 2000 and December 2010 were retrospectively reviewed. Patients with AFP normalization within 1 month after LT were classified into the rapid normalization group (n = 97), with all other patients classified into the non-rapid normalization group (n = 28). Tumor recurrence was observed in 17 of the 97 patients (17.5%) with rapid normalization; of these, 11 patients had high AFP levels and six had normal levels at recurrence. In contrast, tumor recurrence was observed in 24 of the 28 patients (85.7%) without rapid normalization, with all 24 having high AFP levels at recurrence. Multivariate analysis showed that non-rapid normalization (harzard ratio [HR], 4.41, P AFP level at 1 month is a useful clinical marker for HCC recurrence. Therefore, an adjuvant strategy and/or intensive screening are needed for patients who do not show rapid normalization.

    With favourable 5-year survival rates up to 75%, liver transplantation (LT) is the treatment of choice for hepatocellular carcinoma (HCC). Nonetheless, tumour recurrence after LT remains a challenge. The aim of this retrospective study was to develop a predictive score for tumour recurrence after LT by combining clinical parameters with HCC biomarkers (microRNA). A microRNA (miRNA) microarray analysis was used to compare miRNA expression patterns in tissue samples of 40 patients with and without HCC recurrence after LT. In a screening cohort (n = 18), the miRNA analysis identified significant differences in the expression of 13 miRNAs in patients with tumour recurrence. Using the most significant miRNAs in this screening cohort, we could develop a predictive score, which combined the expression levels of miR-214, miR-3187 and the Milan criteria, and we could define low- and high-risk groups for tumour recurrence and death. The above score was evaluated in a second and independent cohort (n = 22). In contrast to the Milan criteria alone, this score was significantly associated with tumour recurrence. Our analysis indicated that the use of a specific miRNA expression pattern in combination with a limited tumour burden as defined by the Milan criteria may lead to a more accurate prediction of tumour recurrence.

    2016-06-01

    The pancreas is an unusual site for tumor metastasis, accounting for only 2% to 5% of all malignancies affecting the pancreas. The more common metastases affecting the pancreas include renal cell carcinomas, melanomas, colorectal carcinomas, breast carcinomas, and sarcomas. Although pancreatic involvement by nonrenal malignancies indicates widespread systemic disease, metastatic renal cell carcinoma to the pancreas often represents an isolated event and is thus amenable to surgical resection, which is associated with long-term survival. As such, it is important to accurately diagnose pancreatic involvement by metastatic renal cell carcinoma on histology, especially given that renal cell carcinoma metastasis may manifest more than a decade after its initial presentation and diagnosis. In this review, we discuss the clinicopathologic findings of isolated renal cell carcinoma metastases of the pancreas, with special emphasis on separating metastatic renal cell carcinoma and its various differential diagnoses in the pancreas.

    Full Text Available Context Acinar cell carcinoma of the pancreas is a rare malignancy, accounting for 1-2% of pancreatic exocrine malignancies. This rarity makes it difficult to standardize a protocol of treatment for acinar cell carcinoma. Case report A 71-year-old male without any particular past history was referred to our institute with abdominal distention and mild liver dysfunction. Computed tomography (CT revealed a cystic lesion with a diameter of 3.5 cm, which originated from the neck of pancreas and had solid nodules inside. Several nodules were demonstrated surrounding the cystic tumor. Laparotomy and histological study demonstrated peritoneal dissemination of acinar cell carcinoma. The patient was treated with S-1 monotherapy (80 mg/m2 for four weeks with a two-week interval as one cycle. After one cycle of S-1 monotherapy, CT demonstrated remarkable shrinkage of the main tumor and disappearance of the nodules on the peritoneum. The patient underwent a radical distal pancreatectomy. The patient was then treated with 16 cycles of S-1 monotherapy after the radical pancreatectomy and remains without any recurrence of the disease two years later. Conclusion Initially inoperable acinar cell carcinoma was treated by monotherapy using S-1, resulting in curative operation and two years disease free survival post operation. S-1 might be more effective on acinar cell carcinoma, rather than gemcitabine

    The traditional view that adult human liver tumors, mainly hepatocellular carcinoma (HCC), arise from mature cell types has been challenged in recent dec-ades. The results of several studies suggest that HCC can be derived from liver stem cells. There are four levels of cells in the liver stem cell lineage: hepatocytes, hepatic stem cells/oval cells, bone marrow stem cells and hepato-pancreas stem cells. However, whether HCC is resulted from the differentiation block of stem cells and, moreover, which liver stem cell lineage is the source cell of hepatocarcinogenesis remain controversial. In this review, we focus on the current status of liver stem cell research and their roles in carcinogenesis of HCC, in order to explore new approaches for stem cell therapy of HCC.

    Purpose: To investigate the rates of tumor response and local control in patients with recurrent small hepatocellular carcinoma (HCC) treated with hypofractionated radiotherapy (RT) as a salvage treatment and to evaluate treatment-related toxicities. Methods and Materials: Between 2006 and 2009, a total of 20 patients with recurrent small HCC were treated with hypofractionated RT after the failure of previous treatment. The eligibility criteria for hypofractionated RT were as follows: 1) HCC less than 5 cm, 2) HCC not adjacent to critical organs, 3) HCC without portal vein tumor thrombosis, and 4) less than 15% of normal liver volume that would be irradiated with 50% of prescribed dose. The RT dose was 50 Gy in 10 fractions. The tumor response was determined by CT scans performed 3 months after the end of RT. Results: The median follow-up period after RT was 22 months. The overall survival rates at 1 and 2 years were 100% and 87.9%, respectively. Complete response (CR) was achieved in seven of 20 lesions (35%) evaluated by CT scans performed 3 months after the end of RT. In-field local control was achieved in 85% of patients. Fourteen patients (70%) developed intra-hepatic metastases. Six patients developed grade 1 nausea or anorexia during RT, and two patients had progression of ascites after RT. There was no grade 3 or greater treatment-related toxicities. Conclusions: The current study showed a favorable outcome with respect to hypofractionated RT for small HCC. Partial liver irradiation with 50 Gy in 10 fractions is considered tolerable without severe complications.

    AIM: To analyze outcomes in patients who underwent liver transplantation(LT) for hepatocellular carcinoma(HCC) and received autologous intraoperative blood salvage(IBS). METHODS: Consecutive HCC patients who underwent LT were studied retrospectively and analyzed according to the use of IBS or not. Demographic and surgical data were collected from a departmental prospective maintained database. Statistical analyses were performed using the Fisher’s exact test and the Wilcoxon rank sum test to examine covariate differences between patients who underwent IBS and those who did not. Univariate and multivariate Cox regression models were developed to evaluate recurrence and death,and survival probabilities were estimated using the Kaplan-Meier method and compared by the log-rank test.RESULTS: Between 2002 and 2012,158 consecutive patients who underwent LT in the same medical center and by the same surgical team were identified. Among these patients,122(77.2%) were in the IBS group and 36(22.8%) in the non-IBS group. The overall survival(OS) and recurrence free survival(RFS) at 5 years were 59.7% and 83.3%,respectively. No differences in OS(P=0.51) or RFS(P=0.953) were detected between the IBS and non-IBS groups. On multivariate analysis for OS,degree of tumor differentiation remained as the only independent predictor. Regarding patients who received IBS,no differences were detected in OS or RFS(P=0.055 and P=0.512,respectively) according to the volume infused,even when outcomes at 90 d or longer were analyzed separately(P=0.518 for both outcomes).CONCLUSION: No differences in RFS or OS were detected according to IBS use. Trials addressing this question are justified and should be designed to detect small differences in long-term outcomes.

    Full Text Available : Granulomatous inflammation is a distinctive pattern of chronic inflammatory reaction characterized by microscopic aggregation of activated macrophages which often develop epithelioid appearance and multinucleate giant cells. Granulomas are encountered in limited number of infectious and some non-infectious conditions. Granulomas have been described within the stroma of malignancies like carcinomas of the breast and colon, seminoma and Hodgkin’s lymphoma, where they represent T-cell-mediated reaction of the tumor stroma to antigens expressed by the tumor. Granulomatous reaction in association with renal cell carcinoma (RCC is uncommon, with only few published reports in the literature. We describe a case of conventional (clear cell RCC associated with epithelioid cell granulomas within the tumor parenchyma.

    This study examines the presence of the EWSR1 rearrangement in a variety of clear cell salivary gland carcinomas with myoepithelial differentiation. A total of 94 salivary gland carcinomas with a prominent clear cell component included 51 cases of clear cell myoepithelial carcinomas de novo (CCMC), 21 cases of CCMCs ex pleomorphic adenoma (CCMCexPA), 11 cases of epithelial-myoepithelial carcinoma (EMC), 6 cases of EMC with solid clear cell overgrowth, and 5 cases of hyalinizing clear cell carcinoma of minor salivary glands. In addition, 10 cases of myoepithelial carcinomas devoid of clear cell change and 12 cases of benign myoepithelioma were included as well. All the tumors in this spectrum were reviewed, reclassified, and tested by fluorescence in situ hybridization (FISH) for the EWSR1 rearrangement using the Probe Vysis EWSR1 Break Apart FISH Probe Kit. The EWSR1 rearrangement was detected in 20 of 51 (39%) cases of CCMC, in 5 of 21 (24%) cases of CCMCexPA, in 1 of 11 (9%) cases of EMC, and in 4 of 5 (80%) cases of hyalinizing clear cell carcinoma. The 25 EWSR1-rearranged CCMCs and CCMCexPAs shared similar histomorphology. They were arranged in nodules composed of compact nests of large polyhedral cells with abundant clear cytoplasm. Necrosis, areas of squamous metaplasia, and hyalinization were frequent features. Immunohistochemically, the tumors expressed p63 (96%), cytokeratin CK14 (96%), and S100 protein (88%). MIB1 index varied from 10% to 100%, with most cases in the 20% to 40% range. Clinical follow-up information was available in 21 cases (84%) and ranged from 3 months to 15 years (mean 5.2 y); 4 patients were lost to follow-up. Ten patients are alive with no evidence of recurrent or metastatic disease in the follow-up period from 3 months to 15 years (mean 5 y), 3 patients are alive with recurrent and metastatic disease, and 8 died of disseminated cancer 9 months to 16 years after diagnosis (mean 6 y).

    Oral squamous cell carcinoma (OSCC) has a high propensity for local failure, which is attributed to recurrence at the primary site or the development of second primary tumors (SPT). Field cancerization that refers to the existence of transformed cells in areas adjacent to the primary tumor, has been attributed to be one of the probable reasons underlying disease relapse. The carcinogenic process necessitates multiple molecular events for the transformation of a normal cell into a cancer cell. This implies that only the long-time residents of the epithelium, such as the stem cells, might be the candidates capable of accumulating these genetic hits. These transformed stem cells- the 'Cancer stem cells' (CSCs), are further known to be equipped with the properties of tumor initiation and migration, both of which are essential for orchestrating field cancerization. The concept that the CSCs might be responsible for field cancerization in OSCC has not been explored extensively. If the role of CSCs as the primary units of field cancerization process is established, their presence in the mucosa adjacent to the tumor may be an indicator for local recurrence and/or development of second primary tumors. In this review, we examine the available evidence in literature exploring the possibilities of CSCs driving the process of field cancerization and thereby being the underlying mechanism for disease recurrence and development of SPT.

    Nearly 50% of patients with oral squamous cell carcinoma (OSCC) die of metastases or locoregional recurrence. Metastasis is mediated by cancer cell adhesion, migration, and invasion. Osteoactivin (OA) overexpression plays a role in metastases in several malignancies. The aims were to determine how integrin interactions modulate OA-induced OSCC cell migration; and to investigate OA effects on cell survival and proliferation. We confirmed OA mRNA and protein overexpression in OSCC cell lines. We assessed OA's interactions with integrins using adhesion inhibition assays, fluorescent immunocytochemistry and co-immunoprecipitation. We investigated OA-mediated activation of mitogen-activated protein kinases (MAPKs) and cell survival. Integrin inhibition effects on OA-mediated cell migration were determined. We assessed effects of OA knock-down on cell migration and proliferation. OA is overexpressed in OSCC cell lines, and serves as a migration-promoting adhesion molecule. OA co-localized with integrin subunits, and co-immunoprecipitated with the subunits. Integrin blocking antibodies, especially those directed against the β1 subunit, inhibited cell adhesion (P = 0.03 for SCC15 cells). Adhesion to OA activated MAPKs in UMSCC14a cells and OA treatment promoted survival of SCC15 cells. Integrin-neutralizing antibodies enhanced cell migration with OA in the extracellular matrix. OA knock-down resulted in decreased proliferation of SCC15 and SCC25 cells, but did not inhibit cell migration. OA in the extracellular matrix promotes OSCC cell adhesion and migration, and may be a novel target in the prevention of HNSCC spread. J. Cell.

    This paper presents a summary of the evidence review group (ERG) report into the clinical effectiveness and cost-effectiveness of topotecan in combination with cisplatin for the treatment of recurrent and stage IVB carcinoma of the cervix, in accordance with the licensed indication, based upon the evidence submission from the manufacturer to the National Institute for Health and Clinical Excellence (NICE) as part of the single technology appraisal (STA) process. The outcomes measured were overall survival, progression-free survival, response rates, adverse effects of treatment, health-related quality of life (HRQoL) and quality-adjusted life-years (QALYs) gained. The manufacturer stated that topotecan plus cisplatin is the only combination regimen to date to have demonstrated a statistically significant survival advantage compared to cisplatin monotherapy in the licensed population. The clinical evidence came from three clinical trials comparing topotecan plus cisplatin with cisplatin monotherapy (GOG-0179), topotecan plus cisplatin with paclitaxel plus cisplatin (GOG-0169), and four cisplatin-based combination therapies: topotecan plus cisplatin, paclitaxel plus cisplatin, gemcitabine plus cisplatin, and vinorelbine plus cisplatin (GOG-0204). Results from GOG-0179 showed greater median overall survival with topotecan plus cisplatin than with cisplatin monotherapy: 9.4 months versus 6.5 months. Similar results were also reported for median progression-free survival. Response rates also showed an advantage with topotecan plus cisplatin compared with cisplatin monotherapy. The response rates in patients receiving cisplatin monotherapy were very low, but the potential reasons for this were not discussed in the manufacturer's submission. Patients receiving topotecan plus cisplatin experienced a greater number of adverse events and the ERG was concerned with some of the assumptions related to HRQoL.

    Full Text Available Abstract Introduction Merkel cell carcinoma is a rare malignant cutaneous neoplasm that is locally invasive and frequently metastasizes to lymph nodes, liver, lungs, bone and brain. The incidence of Merkel cell carcinoma has increased in the past three decades. Case presentation A 65-year-old Caucasian man presented with a sudden onset of severe headache and a three-month history of balance disturbance. Magnetic resonance imaging revealed a large meningeal metastasis. The radiologic workup showed retroperitoneal and inguinal lymph node metastases. Biopsy of the inguinal lymph nodes showed metastases of Merkel cell carcinoma. Biopsy from three different suspected skin lesions revealed no Merkel cell carcinoma, and the primary site of Merkel cell carcinoma remained unknown. Leptomeningeal metastases, new axillary lymph node metastases, and intraspinal (epidural and intradural metastases were detected within six, seven and eight months, respectively, from the start of symptoms despite treating the intracranial metastasis with gamma knife and the abdominal metastases with surgical dissection and external radiotherapy. This indicates the aggressive nature of the disease. Conclusion To the best of our knowledge, this is the first report in the literature of an intracranial meningeal metastasis of Merkel cell carcinoma treated with gamma knife and of intraspinal intradural metastases of Merkel cell carcinoma. Despite good initial response to radiotherapy, recurrence and occurrence of new metastases are common in Merkel cell carcinoma.

    A novel herpesvirus was detected in sun bears (Helarctos malayanus) with oral squamous cell carcinoma. Five captive sun bears from 4 institutions in the United States presented with oral lesions ranging from erythema and mild erosions to nodular, ulcerated masses. All 5 were diagnosed with squamous cell carcinoma. The tumors were treated with surgical resection but recurrence, local extension, or appearance of new lesions was noted in all cases. Intralesional chemotherapy was administered in 2 cases, and the nonsteroidal anti-inflammatory drug piroxicam was administered in 3 cases. Virus was detected in 4 of the 5 bears' tissue samples using a consensus herpesvirus polymerase chain reaction. Nucleotide sequencing and phylogenetic analysis showed that this herpesvirus is in the subfamily Gammaherpesvirinae and distinct from other known herpesviruses. The association between the herpesvirus and squamous cell carcinoma is unknown. The current study presents a novel gammaherpesvirus within the order Ursidae, with the name Ursid herpesvirus 1 proposed.

    Intrathoracic esophageal squamous cell carcinoma was diagnosed by endoscopy in an 11-year-old, castrated male Labrador retriever with signs of regurgitation and weight loss. Photodynamic therapy with photofrin was administered three times under endoscopic guidance over a two-month period. A partial response to photodynamic therapy was supported by a reduction in tumor size (noted on serial endoscopic examinations) and by a return to oral alimentation. The dog was euthanized due to recurrent regurgitation and aspiration pneumonia nine months after the onset of therapy. Necropsy revealed marked local invasiveness and regional lymph node metastasis of the esophageal squamous cell carcinoma in addition to pneumonia. The application of photodynamic therapy in the treatment of canine esophageal squamous cell carcinoma is discussed and compared with the human literature.

    We report a retroperitoneal transitional cell carcinoma arising from the primitive urogenital remnants of a 56-year-old married Indian woman. She presented with a huge cystic mass in the hypogastrium and right iliac fossa, which extended into the right thigh as a massive dumb-bell tumour. On exploration, it was found not to be arising from any known retroperitoneal structure. The mass was excised, and the histopathology confirmed transitional cell carcinoma with positive margins. Though she received postoperative chemotherapy with cyclophosphamide, adriamycin and cisplatin, she developed extensive local recurrence and hepatic secondaries, and succumbed to the disease after ten months of follow-up. We highlight the rarity of the disease, its atypical presentation as a cystic dumb-bell lump, its diagnostic challenges and aggressive behaviour, and review the literature on primary retroperitoneal transitional cell carcinomas.

    2012-05-01

    Full Text Available Objective: The aim of this study was to investigate p53 and COX-2 expressions in basal cell carcinoma, squamous cell carcinoma and actinic keratoses, and to determine a possible relationship.Material and Method: 50 basal cell carcinoma, 45 squamous cell carcinoma and 45 actinic keratosis cases were evaluated. The type of tumor in basal cell carcinoma and tumor differentiation in squamous cell carcinoma were noted and the paraffin block that best represented the tumor was chosen. Immunostaining by p53 and COX-2 was performed on sections of the paraffin blocks.Results: p53 expression was observed in 98% of basal cell carcinoma, 88.9% of squamous cell carcinoma and all actinic keratosis cases. p53 expression was also noted in non-dysplastic appearing epithelium in actinic keratosis cases. COX-2 expression was seen in 90, 100 and 88.9% of the basal cell carcinoma, squamous cell carcinoma and actinic keratosis groups, respectively. Skin appendages, inflammatory cells and vascular structures were also stained by COX-2 besides tumor tissue. COX-2 expression increased by the p53 expression increase in basal cell carcinoma and squamous cell carcinoma. p53 and COX-2 expressions were not related in terms of tumor type in the BCC and were not related in terms of differentiation in SCC.Conclusion: The existence of p53 expression in actinic keratosis cases has supported the idea that p53 plays a role in the early steps of carcinogenesis in skin cancers. The fact that the expression of COX-2 increases in line with the increase of p53 expression in basal cell carcinoma and squamous cell carcinoma cases indicates that COX-2 expression may be affected by p53

    Full Text Available Abstract Background In women with duct carcinoma in-situ (DCIS receiving breast conservation therapy (BCT, in-breast recurrences are seen in approximately 10%, but cannot be accurately predicted using clinical and histological criteria. We performed a case-control study to identify protein markers of local recurrence risk in DCIS. Methods Women treated for DCIS with BCT, who later developed in-breast recurrence (cases were matched by age and year of treatment to women who remained free of recurrence (controls. Results A total of 69 women were included in the study, 31 cases and 38 controls. Immunohistochemical evaluation of DCIS tissue arrays was performed for estrogen receptor, progesterone receptor, HER-2/neu, cyclin D1, p53, p21, cycloxygenase-2 (COX-2 and peroxisome proliferator activated receptor γ (PPARγ. Two markers were significantly different between cases and controls on univariate analysis: strong COX-2 expression was associated with increased risk of recurrence, with 67% vs. 24% positivity in cases and controls p = 0.006; and nuclear expression of PPARγ was associated with protection from recurrence with 4% vs. 27% positivity in cases and controls, p = 0.024. In a multivariate model which included size, grade, COX-2 and PPARγ positivity, we found COX-2 positivity to be a strong independent risk factor for recurrence (OR 7.90, 95% CI 1.72–36.23., whereas size and grade were of borderline significance. PPARγ expression continued to demonstrate a protective trend, (OR 0.14, 95% CI 0.06–1.84. Conclusion Our findings suggest that COX-2 and PPARγ should be investigated further as biologic markers to predict DCIS recurrence, particularly since they are also potential therapeutic targets.

    BACKGROUND: Cancer of the pancreas is the fourth leading cause of cancer death in industrialized countries. In malignancy, actively proliferating cells may be effectively targeted and killed by anti-cancer therapies, but stem cells may survive and support re-growth of the tumor. Thus, new strategies for the treatment of cancer clearly will also have to target cancer stem cells. The goal of the present study was to determine whether pancreatic carcinoma cell growth may be driven by a subpopulation of cancer stem cells. Because previous data implicated ABCG2 and CD133 as stem cell markers in hematopoietic and neural stem/progenitor cells, we analyzed the expression of these two proteins in pancreatic carcinoma cell lines. METHODS:Five established pancreatic adenocarcinoma cell lines were analyzed. Total RNA was isolated and real-time RT-PCR was performed to determine the expression of ABCG2 and CD133. Surface expression of ABCG2 and CD133 was analyzed by lfow cytometric analysis. RESULTS:All pancreatic carcinoma cell lines tested expressed signiifcantly higher levels of ABCG2 than non-malignant ifbroblasts or two other malignant non-pancreatic cell lines, i.e., SaOS2 osteosarcoma and SKOV3 ovarian cancer. Elevated CD133 expression was found in two out of ifve pancreatic carcinoma cell lines tested. Using lfow cytometric analysis we conifrmed surface expression of ABCG2 in all ifve lines. Yet, CD133 surface expression was detectable in the two cell lines, A818-6 and PancTu1, which exhibited higher mRNA levels. CONCLUSIONS: Two stem cell markers, ABCG2 and CD133 are expressed in pancreatic carcinoma cell lines. ABCG2 and/or CD133 positive cells may represent subpopulation of putative cancer stem cells also in this malignancy. Because cancer stem cells are thought to be responsible for tumor initiation and its recurrence after an initial response to chemotherapy, they may be a very promising target for new drug developments.

    Objective: to evaluate the effect of time between surgery and postoperative radiation therapy on local recurrence of squamous cell carcinoma of the tongue and floor of the mouth. Methods: a total of 154 patients treated between 1996 and 2007 were selected considering local recurrence rate and time of the adjuvant radiotherapy. Results: local recurrence was diagnosed in 54 (35%) patients. Radiation therapy reduced the rate of local recurrences, although with no statistical significance. The time between surgery and initiation of postoperative radiotherapy did not significantly influence the risk of local recurrence in patients referred to adjuvant treatment (p=0.49). Conclusion: in the presence of risk factors for local recurrence, a short delay in starting the adjuvant radiation therapy does not contraindicate its performance. (author)

    Background Due to the rarity of adenoid cystic carcinoma (ACC), information on outcome is based upon small retrospective case series. The aim of our study was to create a large multiinstitutional international dataset of patients with ACC in order to design predictive nomograms for outcome. Methods ACC patients managed at 10 international centers were identified. Patient, tumor, and treatment characteristics were recorded and an international collaborative dataset created. Multivariable competing risk models were then built to predict the 10 year recurrence free probability (RFP), distant recurrence free probability (DRFP), overall survival (OS) and cancer specific mortality (CSM). All predictors of interest were added in the starting full models before selection, including age, gender, tumor site, clinical T stage, perineural invasion, margin status, pathologic N-status, and M-status. Stepdown method was used in model selection to choose predictive variables. An external dataset of 99 patients from 2 other institutions was used to validate the nomograms. Findings Of 438 ACC patients, 27.2% (119/438) died from ACC and 38.8% (170/438) died of other causes. Median follow-up was 56 months (range 1–306). The nomogram for OS had 7 variables (age, gender, clinical T stage, tumor site, margin status, pathologic N-status and M-status) with a concordance index (CI) of 0.71. The nomogram for CSM had the same variables, except margin status, with a concordance index (CI) of 0.70. The nomogram for RFP had 7 variables (age, gender, clinical T stage, tumor site, margin status, pathologic N status and perineural invasion) (CI 0.66). The nomogram for DRFP had 6 variables (gender, clinical T stage, tumor site, pathologic N-status, perineural invasion and margin status) (CI 0.64). Concordance index for the external validation set were 0.76, 0.72, 0.67 and 0.70 respectively. Interpretation Using an international collaborative database we have created the first nomograms which

    Full Text Available Renal cell carcinoma metastasis to the small intestine is a rare condition. It usually results in gastrointestinal bleeding and it could happen many years after the diagnosis with renal cell cancer. Treatment includes surgery as well as targeted agents such as tyrosine kinases. We report here the case of an 82-year-old man with a past medical history of high-grade renal cell carcinoma and right nephrectomy 6 years earlier, who presented with recurrent episodes of syncope and black stools. He underwent esophagogastroduodenoscopy (EGD and colonoscopy without evident source of bleeding. Video capsule endoscopy (VCE showed three bleeding lesions in the jejunum and ileum. Push enteroscopy revealed a proximal jejunum bleeding mass that was suspicious for malignancy. Histopathology demonstrated poorly differentiated carcinoma. Given the patient’s history of high-grade renal cell carcinoma, and similarity of histologic changes to the old renal cell cancer specimen, metastatic renal cell carcinoma was felt to be the responsible etiology.

    Basaloid squamous cell carcinoma of the esophagus is a rare variant of squamous cell carcinoma. We reviewed 878 cases of esophageal squamous cell carcinoma and detected 22 cases (3%) of basaloid squamous cell carcinoma. These tumors and stage-matched paired conventional squamous cell carcinomas were investigated for clinicopathologic features and immunoreactivity of cytokeratin subtypes, p53, B-cell lymphoma 2 (bcl-2), β-catenin, and epidermal growth factor receptor. Molecular aberrations in p53, CTNNB1 (the gene encoding β-catenin), and epidermal growth factor receptor (EGFR) were also determined. Patients with basaloid squamous cell carcinomas demonstrated a 5-year survival rate of 42%, significantly worse than those with well-differentiated squamous cell carcinoma (Pcarcinomas, the basaloid squamous cell carcinomas were less immunoreactive for cytokeratin 14, cytokeratin 903, and membranous β-catenin (Pcarcinomas, low-level expression of cytokeratin 14/cytokeratin 903 and mutations of p53 and EGFR had a significant influence on worse survival (Pcarcinoma, a neoplasm with particularly aggressive biologic behavior, should be differentiated from conventional squamous cell carcinomas. In this context, immunohistochemical assessment of several markers might provide a useful adjunct diagnostic tool. Aberrations of p53 and epidermal growth factor receptor genes are possibly involved in progression of esophageal basaloid squamous cell carcinoma.

    The presence of pleomorphic tumor giant cells in thyroid carcinomas of follicular cell origin is always worrisome for the pathologist as they first of all refer to anaplastic carcinoma, one of the most aggressive human malignancies. However, non-anaplastic pleomorphic giant cells are well described in other thyroid diseases, most often benign. In this paper, we describe four cases of papillary thyroid carcinoma displaying pleomorphic tumor giant cells with features that differ from those of anaplastic carcinoma. Pleomorphic giant cells were admixed with the underlying thyroid carcinoma and constituted from 5% to 25% of the tumor. Cytologically, they had an abundant eosinophilic cytoplasm with large and irregular nuclei. Compared to pleomorphic giant cells of anaplastic carcinoma, they reproduced the growth pattern of the underlying carcinoma, had a low mitotic index without necrosis or inflammation, and were reactive with thyroglobulin and thyroid-specific transcription factor-1 and strongly and diffusely positive for cytokeratin AE1/AE3. After 16-84 months of follow-up, patients are relapse-free and still alive. These cases show that pleomorphic tumor giant cells arising in papillary thyroid carcinomas do not always represent dedifferentiation and progression to anaplastic carcinoma. Distinction among these processes is critical as their treatment and prognosis are very different.

    1987-03-01

    The pharmacokinetics of mitomycin C as a single agent have been determined in 25 treatment courses given to 18 patients with recurrent or metastatic colorectal carcinoma using a high performance liquid chromatography (HPLC) assay to analyze plasma and urine samples. The plasma pharmacokinetics conformed to a two-compartment linear model in 21 of 25 courses monitored with a mean t1/2 lambda 1 of 9.8 +/- 1.2 (SEM) min and mean t1/2 lambda z of 64.1 +/- 8.9 (SEM) min. The large variation observed in t1/2 lambda z was not related to dose or treatment, but an interaction of these two factors approached significance (p = 0.057). Renal excretion in the 12 courses in which it was determined averaged only 2.3% of the total administered dose during the first 4 h monitored and no mitomycin C metabolites were detected in plasma or urine by the HPLC technique used. The most common toxicity, thrombocytopenia, did not correlate with t1/2 lambda z or the area under the curve. This may be due to a failure to monitor active metabolites of mitomycin C; other factors besides plasma drug concentrations that mediate toxicity towards marrow elements; or the small number of courses associated with thrombocytopenia (less than 100,000/mm3). Our study indicates that an interaction of drug dose and treatment course may be associated with increasing t1/2 lambda z; the renal clearance contributes a small component of mitomycin C elimination; metabolites of mitomycin C cannot be detected by the present HPLC technique; and routine monitoring of mitomycin C using present methods cannot be recommended for clinical use to predict toxicity.

    Full Text Available The down-regulation of miR-214 has previously been observed in human hepatocellular carcinoma (HCC. Here, we demonstrated the down-regulation of miR-214 is associated with cell invasion, stem-like traits and early recurrence of HCC. Firstly, we validated the suppression of miR-214 in human HCC by real-time quantitative RT-PCR (qRT-PCR in 20 paired tumor and non-tumor liver tissues of HCC patients and 10 histologically normal liver tissues from colorectal cancer patients with liver metastases. Further qRT-PCR analysis of 50 HCC tissues from an independent cohort of HCC patients of whom 29 with early recurrent disease (<2 years and 21 with late recurrent disease demonstrated that the suppression of miR-214 was significantly more suppressed in samples from HCC patients with early recurrent disease compared those from patients with no recurrence. Re-expression of miR-214 significantly suppressed the growth of HCC cells in vitro and reduced their tumorigenicity in vivo. The enhancer of zeste homologue 2 (EZH2 and β-catenin (CTNNB1 was identified as two potential direct downstream targets of miR-214 through bioinformatics analysis and experimentally validated the miRNA-target interactions with a dual-firefly luciferase reporter assay. In corroborate with this, both EZH2 and CTNNB1 are found to be significantly overexpressed in human HCC biopsies. Since EZH2 can regulate CTNNB1, CTNNB1 can also be an indirect target of miR-214 through EZH2. Silencing EZH2 or CTNNB1 expression suppressed the growth and invasion of HCC cells and induced E-cadherin (CDH1, known to inhibit cell invasion and metastasis. Furthermore, the silencing of miR-214 or overexpression of EZH2 increased EpCAM(+ stem-like cells through the activation of CTNNB1. Interestingly, the up-regulation of EZH2, CTNNB1 and the down-regulation of CDH1 in HCC patients correlated with early recurrent disease and can be an independent predictor of poor survival. Therefore, miR-214 can directly or

    Full Text Available Abstract Background Leptomeningeal carcinomatosis occurs in patients with cancer at the rate of approximately 5%; it develops particularly in patients with breast cancer, lung cancer, melanoma, leukemia, or malignant lymphoma. We describe a rare case of leptomeningeal carcinomatosis in which spinal intradural squamous cell carcinoma with no lesions in the cerebral meninges and leptomeninx, was the primary lesion. Methods A 64-year-old man complained of sacral pain. Although the patient was treated with analgesics, epidural block and nerve root block, sacral pain persisted. Since acute urinary retention occurred, he was operated on. The patient was diagnosed as having an intradural squamous cell carcinoma of unknown origin. Results Since the patient presented with a slightly decreased level of consciousness 2 months after surgery, he was subjected to MRI scanning of the brain and spinal cord, which revealed disseminated lesions in the medulla oblongata. The patient died of pneumonia and sepsis caused by methicillin-resistant Staphylococcus aureus 5 months after surgery. Conclusion We report the first case of a patient with intradural squamous cell carcinoma with unknown origin that developed independently in the sacrum.

    To determine the computed tomographic (CT) characteristics of nonfunctioning islet cell carcinoma of the pancreas, the CT scans of 27 patients with that disease were reviewed. The pancreatic tumor was identified as a mass in 26 patients (96%) Of the 25 tumors evaluated with contrast enhancement, 20 became partially diffusely hyperdense relative to nearby normal pancreatic tissue. Hepatic metastases were identified in 15 patients (56%), regional lymphadenopathy in 10 (37%), atrophy of the gland proximal to the tumor in six (22%), dilatation of the biliary ducts in five (19%), and dilatation of the pancreatic duct in four (15%). The CT appearances of the nonfunctioning islet cell tumors were compared with those of 100 ordinary (ductal) pancreatic adenocarcinomas. Although the two types of tumors were sometimes indistinguishable, features found to be more characteristic of islet cell carcinoma included a pancreatic mass of unusually large size, calcification within the tumor, and contrast enhancement of either the primary tumor or hepatic metastases. Involvement of the celiac axis or proximal superior mesenteric artery was limited to ductal carcinoma.

    The time course of human papillomavirus (HPV) DNA clearance was studied in patients with carcinoma of the cervix during follow-up after primary radical radiotherapy (RT). This study investigated the relationship between timing of HPV clearance and RT effectiveness. A total of 71 consecutive patients who were treated for cervical cancer with primary radical radiotherapy and high-dose rate intracavitary brachytherapy with or without chemotherapy were enrolled in the study. Samples for HPV DNA examination were taken before (1) treatment, (2) every brachytherapy, and (3) every follow-up examination. The times when HPV DNA was undetected were analyzed for association with recurrence-free survival. HPV DNA was not detected in 13 patients (18 %) before RT. Of the 58 patients with HPV DNA detected before treatment, HPV DNA was not detected in 34 % during treatment and in 66 % after the treatment. Within 6 months after RT, HPV DNA was detected in 0 % of all patients. The patients were followed up for a median period of 43 months (range 7-70 months). In all, 20 patients were found to develop recurrence. The 3-year cumulative disease-free survival (DFS) rate was 71 ± 5.4 % for all 71 patients. In multivariate analysis, DFS was significantly associated with HPV (detected vs. not detected) with a hazard ratio of 0.07 (95 % confidence interval 0.008-0.6, p = 0.009). In this study, patients in whom HPV was not detected had the worst prognosis. Six months after RT, HPV DNA was detected in 0 % of the patients. Patients in whom HPV DNA could not be detected before treatment need careful follow-up for recurrence and may be considered for additional, or alternative treatment. (orig.)

    We report a case of primary small cell carcinoma of the urinary bladder. A 79-year-old man with the chief complaints of macrohematuria and pollakisuria was admitted to our hospital. Cystoscopy and computed tomography (CT) revealed a non-papillary broad-based bladder tumor. Histological diagnosis was small cell carcinoma of the urinary bladder, and he underwent 3 courses of neoadjuvant chemotherapy including gemcitabine and cisplatin with a preoperative diagnosis of cT3bN0M0. After the chemotherapy, cystoscopy and CT showed complete remission. Total cystectomy with ileal conduit was performed following 3 courses of chemotherapy. Microscopic examination revealed that the small cell carcinoma had disappeared and the converted squamous cell carcinoma remained only in a small part of the specimens. The patient was carefully followed for 10 months after operation, with no tumor recurrence.

    Laryngeal squamous cell carcinoma (LSCC) recurrences are very difficult to manage in elderly patients (age ≥65 years), because treatment carries significant morbidity and mortality. The aim of this study was to develop a panel of parameters (clinicopathological variables or biomarkers) to improve our ability to detect elderly patients at higher risk of LSCC recurrence. Maspin, nm23-H1, and CD105 were investigated using immunohistochemistry on surgical specimens from 46 elderly patients treated for LSCC. After univariate analysis identified parameters associated with LSCC recurrence, a multivariate prognostic model was constructed. At univariate analysis, a higher recurrence rate was significantly associated with nm23-H1 nuclear expression in carcinoma cells ≤2.0% (p = 0.01), CD105 expression in intratumoral vascular endothelial cells ≥5.28% (p = 0.04), and pN+ status (p = 0.04). Multivariate modeling confirmed that nuclear nm23-H1 ≤2.0% (p = 0.009) and CD105 ≥5.28% (p = 0.013) had a negative prognostic significance in terms of disease recurrence, while pN+ status showed a trend toward significance (p = 0.05). We thus obtained a panel comprising two biomarkers and neck lymph node status that revealed an excellent discriminatory power [AUC (ROC) of 0.81] in terms of the risk of LSCC recurrence. The panel achieved a specificity of 96% and a positive predictive value of 93%. We identified a panel with an excellent discriminatory power in identifying elderly patients at higher risk of recurrence after treatment for LSCC. These patients would benefit from a more aggressive primary treatment.

    Full Text Available Abstract Background Fascin is a globular actin cross-linking protein, which plays a major role in forming parallel actin bundles in cell protrusions and is found to be associated with tumor cell invasion and metastasis in various type of cancers including oral squamous cell carcinoma (OSCC. Previously, we have demonstrated that fascin regulates actin polymerization and thereby promotes cell motility in K8-depleted OSCC cells. In the present study we have investigated the role of fascin in tumor progression of OSCC. Methods To understand the role of fascin in OSCC development and/or progression, fascin was overexpressed along with vector control in OSCC derived cells AW13516. The phenotype was studied using wound healing, Boyden chamber, cell adhesion, Hanging drop, soft agar and tumorigenicity assays. Further, fascin expression was examined in human OSCC samples (N = 131 using immunohistochemistry and level of its expression was correlated with clinico-pathological parameters of the patients. Results Fascin overexpression in OSCC derived cells led to significant increase in cell migration, cell invasion and MMP-2 activity. In addition these cells demonstrated increased levels of phosphorylated AKT, ERK1/2 and JNK1/2. Our in vitro results were consistent with correlative studies of fascin expression with the clinico-pathological parameters of the OSCC patients. Fascin expression in OSCC showed statistically significant correlation with increased tumor stage (P = 0.041, increased lymph node metastasis (P = 0.001, less differentiation (P = 0.005, increased recurrence (P = 0.038 and shorter survival (P = 0.004 of the patients. Conclusion In conclusion, our results indicate that fascin promotes tumor progression and activates AKT and MAPK pathways in OSCC-derived cells. Further, our correlative studies of fascin expression in OSCC with clinico-pathological parameters of the patients indicate that fascin may prove to be useful in prognostication and

    Full Text Available Malignant sinonasal carcinomas are a rare entity comprising less than 1% of all cancers and around 3% of all head and neck malignancies seen in humans. Among these 15-20% are transitional cell carcinoma also known as non keratinizing carcinoma of sinonasal tract. We are reporting the case of a 45 years female with history of nasal obstruction and epistaxis. A contrast enhanced computed tomography (CECT was done which showed mucosal thickening in the right nasal cavity. Endoscopy assisted biopsy was taken which revealed non keratinizing carcinoma (transitional type. Very few reported cases of this type of malignancy was found. A possible reason could be multiple synonyms like cylindrical cell carcinoma, Schneiderian carcinoma and transitional cell carcinoma.

    Anal sac squamous cell carcinoma is rare in dogs. Five cases have been previously reported, treatment of which involved surgery alone. This report describes three further cases of canine anal sac squamous cell carcinoma which underwent medical (meloxicam) management alone, resulting in survival of up to seven months. No metastases were identified. Squamous cell carcinoma, although extremely uncommon, should be considered as a possible differential diagnosis when a dog is presented for investigation of an anal sac mass.

    Squamous cell carcinoma arising from balanitis xerotica obliterans is rarely reported. We describe an 83-year-old man in whom metastatic penile squamous cell carcinoma developed after 18 years of observation for balanitis xerotica obliterans. It is important to recognize the possibility of this uncommon complication of balanitis xerotica obliterans, because survival of patients with squamous cell carcinoma depends on early diagnosis and treatment.

    Management of intractable haematuria and obstructive urosepsis from upper tract urothelial carcinoma can be problematic in patients not suitable for surgery, chemotherapy or radiotherapy. Interventional radiology techniques provide alternative approaches in this setting, such as complete kidney embolization to cease urine output, percutaneous nephrostomy, antegrade injection of sclerotherapy agents and sterilisation of the upper collecting system. Related approaches have been successfully employed to sclerose renal cysts, lymphoceles, chyluria and intractable lower tract haemorrhage. No reports of percutaneous, antegrade sclerotherapy in the upper urinary tract have previously been published. We present a case of recurrent haematuria and obstructive urosepsis caused by invasive upper tract urothelial carcinoma in a non-operative patient, which was treated with renal embolisation and percutaneous upper tract urothelial sclerotherapy.

    Full Text Available Abstract Background Epigenetic alterations are a hallmark of human cancer. In this study, we aimed to investigate whether aberrant DNA methylation of cancer-associated genes is related to urinary bladder cancer recurrence. Methods A set of 4 genes, including CDH1 (E-cadherin, SFN (stratifin, RARB (retinoic acid receptor, beta and RASSF1A (Ras association (RalGDS/AF-6 domain family 1, had their methylation patterns evaluated by MSP (Methylation-Specific Polymerase Chain Reaction analysis in 49 fresh urinary bladder carcinoma tissues (including 14 cases paired with adjacent normal bladder epithelium, 3 squamous cell carcinomas and 2 adenocarcinomas and 24 cell sediment samples from bladder washings of patients classified as cancer-free by cytological analysis (control group. A third set of samples included 39 archived tumor fragments and 23 matched washouts from 20 urinary bladder cancer patients in post-surgical monitoring. After genomic DNA isolation and sodium bisulfite modification, methylation patterns were determined and correlated with standard clinic-histopathological parameters. Results CDH1 and SFN genes were methylated at high frequencies in bladder cancer as well as in paired normal adjacent tissue and exfoliated cells from cancer-free patients. Although no statistically significant differences were found between RARB and RASSF1A methylation and the clinical and histopathological parameters in bladder cancer, a sensitivity of 95% and a specificity of 71% were observed for RARB methylation (Fisher's Exact test (p RASSF1A gene, respectively, in relation to the control group. Conclusion Indistinct DNA hypermethylation of CDH1 and SFN genes between tumoral and normal urinary bladder samples suggests that these epigenetic features are not suitable biomarkers for urinary bladder cancer. However, RARB and RASSF1A gene methylation appears to be an initial event in urinary bladder carcinogenesis and should be considered as defining a panel of

    Background and purpose: This retrospective study was to evaluate the local control and survival of {sup 125}I brachytherapy for recurrent and/or locally advanced adenoid cystic carcinoma (ACC) of the oral and maxillofacial region. Patients and methods: A total of 38 patients with recurrent and/or locally advanced ACC of the oral and maxillofacial region received {sup 125}I brachytherapy alone from 2001-2010. Twenty-nine were recurrent cases following previous surgery and radiation therapy. The other 9 cases involved primary tumors. Overall, 12 tumors were located in the major salivary glands, 12 in the minor salivary glands, and 14 in the paranasal region, the nasal cavity or the skull base. The prescribed dose was 100-160 Gy. Results: Patients were followed for 12-122 months (median 51 months). The 2-, 5-, and 10-year local tumor control rates were 86.3, 59, and 31.5 %, respectively. The 2-, 5-, and 10-year overall survival rates were 92.1, 65 and 34.1 %, respectively. Tumors > 6 cm had significantly lower local control and survival rates. No severe complications were observed during follow-up. Conclusion: {sup 125}I brachytherapy is a feasible and effective modality for the treatment of locally advanced unresectable or recurrent ACC.

    Full Text Available Recurrent invasive high-grade mucoepidermoid carcinoma of the larynx and hypopharynx is a rare occurrence. These tumors have been commonly associated with salivary gland tumors, most commonly the parotid gland. The patient usually presents with the following symptoms: hoarseness (if larynx is involved, or changes in voice character, sore throat, cough, odynophagia, dysphagia, otalgia, difficulty breathing, weight loss, lymphadenopathy. Here we present a case of a recurrent invasive high-grade mucoepidermoid carcinoma of larynx and hypopharynx. The patient was a 67- year-old male that originally presented in 2006. At that time he underwent a wide field laryngectomy, right thyroid lobectomy, and biopsy of the right digastric node. He was a clinical stage III, pT3N0M0. No adjuvant radiation therapy was given at that time. The patient remained asymptomatic until February 2014, when he presented with dysphagia and neck swelling. Positron emission tomography/computed tomography showed evidence of recurrence. The patient was treated with definitive intensity modulated radiation therapy (IMRT with concurrent chemotherapy. Treatment for this disease is gathered by scattered case reports. If surgery is a possibility it is considered as first line therapy. Post-surgical radiation is then offered. However, in this case the recurrent tumor was located near the carotid artery, and thus surgery was not a possibility. Therefore, concurrent chemotherapy and radiation with IMRT and weekly cis-platinum was given. While the optimum combination of treatment has not yet been established because of the rarity of this cancer’s location site, the current patient appeared to have an excellent response from the definitive IMRT and chemotherapy treatment.

  16. Histopathological transformation to small-cell lung carcinoma in non-small cell lung carcinoma tumors.

    Lung cancer is the principal cause of cancer-related death worldwide. The use of targeted therapies, especially tyrosine kinase inhibitors (TKIs), in specific groups of patients has dramatically improved the prognosis of this disease, although inevitably some patients will develop resistance to these drugs during active treatment. The most common cancer-associated acquired mutation is the epidermal growth factor receptor (EGFR) Thr790Met (T790M) mutation. During active treatment with targeted therapies, histopathological transformation to small-cell lung carcinoma (SCLC) can occur in 3-15% of patients with non-small-cell lung carcinoma (NSCLC) tumors. By definition, SCLC is a high-grade tumor with specific histological and genetic characteristics. In the majority of cases, a good-quality hematoxylin and eosin (H&E) stain is enough to establish a diagnosis. Immunohistochemistry (IHC) is used to confirm the diagnosis and exclude other neoplasia such as sarcomatoid carcinomas, large-cell carcinoma, basaloid squamous-cell carcinoma, chronic inflammation, malignant melanoma, metastatic carcinoma, sarcoma, and lymphoma. A loss of the tumor-suppressor protein retinoblastoma 1 (RB1) is found in 100% of human SCLC tumors; therefore, it has an essential role in tumorigenesis and tumor development. Other genetic pathways probably involved in the histopathological transformation include neurogenic locus notch homolog (NOTCH) and achaete-scute homolog 1 (ASCL1). Histological transformation to SCLC can be suspected in NSCLC patients who clinically deteriorate during active treatment. Biopsy of any new lesion in this clinical setting is highly recommended to rule out a SCLC transformation. New studies are trying to assess this histological transformation by noninvasive measures such as measuring the concentration of serum neuron-specific enolase.

    BACKGROUND:With the maturation and popularization of skills in liver transplantation (LT), patients with hepatocellular carcinoma (HCC) have an alternative choice. LT as a curative treatment for HCC provides good liver function and systemic condition to recipients. Preoperative tumor characteristics are critical in selecting optimal candidates for LT to optimize the use of donor livers and to achieve a long-term survival. The present study aimed to elucidate the risk factors of HCC involved in fatal recurrence in the ifrst year after LT and to investigate their utility in selecting suitable candidates for LT. METHODS:From April 2002 to October 2005, 303 patients who had received orthotopic LT for HCC were reviewed. Of these patients, those with diffuse intrahepatic or multiple systemic recurrent lesions who died within 1 year after surgery were investigated as fatal recurrence group (48 patients) and the remaining patients including those who were disease-free without recurrence, those who were alive with recurrence in the ifrst year, or those who died in the ifrst year of other causes, served as control group (255). The two groups were compared by demographics, tumor, and histopathological characteristics for their prognostic signiifcance by logistic regression analysis. RESULTS:Multivariate analysis between the fatal recurrence group and the control group showed that the presence of vascular invasion, a tumor size greater than 6.5 cm, and a preoperative serum alpha-fetoprotein (AFP) level greater than 1000 μg/L were risk factors for fatal recurrence. Increased risk factors reduced the suitability of candidates for LT and diminished survival in the ifrst year. 85.71% of the patients with all three risk factors, 37.84%of those with two factors, 13.64%of those with one factor, and 6.71%of those without risk factors died from tumor recurrence within 1 year after transplantation. CONCLUSIONS:Vascular invasion, tumor size ≥6.5 cm, and preoperative serum AFP level

    The prognosis of hepatocellular carcinoma (HCC) treated by radiofrequency ablation (RFA) is mainly associated with tumor recurrence. So far, no tissue biomarker of recurrence has been confirmed in biopsy specimens. Previous studies have reported that aberrant expression of microRNA-34a (miR-34a) is involved in oncogenesis and progression of HCC. The aim of this study was to investigate the prognostic value of tissue miR-34a expression in patients with HCC treated with RFA. Patients with early-stage single-nodule HCC treated with RFA were included, and tissue expression of miR-34a were assessed by quantitative reverse-transcription polymerase chain reaction. Main clinical endpoints were overall and early recurrence. The Kaplan-Meier method was used to plot recurrence curves and univariable and multivariable Cox regression analyses were performed to assess independent predictive factors for recurrence. Of 120 patients, recurrence occurred in 67 patients (55.8 %) with a median follow-up of 31 months. Forty-one patients (34.2 %) recurred within 2 years after RFA. The median miR-34a level was 0.87 (range 0.06-21.54). Low miR-34a level was associated with larger tumor size (P = 0.033) and higher serum alpha-fetoprotein (AFP) level (P = 0.004). When analyzed with a Cox regression model, the two independent predictive factors for overall recurrence were high serum AFP level (hazard ratio [HR] = 1.21; 95 % confidence interval [CI] = 1.04-1.36; P = 0.039) and low miR-34a level (HR = 1.44; 95 % CI = 1.13-1.72; P = 0.011). The expression of miR-34a was also an independent predictive factor for early recurrence (HR = 1.49; 95 % CI = 1.15-1.79; P = 0.008). Taken together, this study suggests that the expression of miR-34a in HCC biopsy specimens has an independent predictive value of early recurrence after RFA.

    Full Text Available Merkel cell carcinoma is a rare, aggressive, malignant cutaneous tumor. It usually appears on the sun-exposed areas such as the head and neck in the elderly. A 72-year-old female patient was admitted to our clinic with the complaints of a big mass on her face. She described that the mass on her left cheek rapidly grew in three months. Her family and own medical history was unremarkable for skin cancers. On physical examination, there were no pathological findings except for a palpable submandibular lymphadenopathy. Dermatological examination revealed a giant tumoral lesion 9x9 cm in diameter, containing crusted and ulcerated areas on her left cheek. Histopathological examination of the specimen obtained from the lesion showed a neoplastic infiltration consisting small, atypic cells with big, round, hyperchromatic nucleus, narrow cytoplasms, and prominent nucleoulus in some areas, showing high mitotic activity. The neoplasm, which had apoptotic bodies and necrobiosis, also invaded the full thickness of the skin, and the epidermis was very thin. In immunochemistry, CK20 was strongly positive, S100 was focally positive, and EMA was positive, while synaptophysin, chromogranin, vimentin, CD3, CD20, as well as CD45, and CD99 were all negative. Based on these findings, the patient was diagnosed as having Merkel cell carcinoma. On the systemic screening for metastases, nodular lesions in the lungs compatible with metastases were detected on computed tomography. By the consultations with plastic and reconstructive surgeons and oncologists, she was accepted as inoperable and etoposide monotherapy was administered. In this report, we aimed to underline the importance of early diagnosis while presenting a case of giant Merkel cell carcinoma which shows an aggressive progression with lung metastases.

    Full Text Available Cervical carcinoma is the most common malignancy of the female genital tract and represents the second most common malignancy in women worldwide. Histologically 85 to 90% of cervical cancers are squamous cell carcinoma. Osteoclastic giant cell rich squamous cell carcinoma is an unusual histological variant of which only 4 cases have been reported. We present the case of a 49-year-old woman with a 6-month history of irregular vaginal bleeding. Examination revealed a 2.7 cm polypoid mass in the anterior lip of the uterine cervix. The patient underwent hysterectomy with bilateral salpingo-oophorectomy. Microscopically the tumor was composed of infiltrative nests of poorly differentiated nonkeratinizing squamous cell carcinoma. Interspersed in between these tumor cells were numerous osteoclastic giant cells with abundant eosinophilic cytoplasm devoid of nuclear atypia, hyperchromatism, or mitotic activity. Immunohistochemistry was performed; CK and P63 were strongly positive in the squamous component and negative in the osteoclastic giant cells, while CD68 and Vimentin were strongly positive in the giant cell population and negative in the squamous component. The patient received chemo- and radiotherapy for recurrent disease identified 3 months later on a follow-up CT scan; 7 months after the surgical procedure the patient is clinically and radiologically disease-free.

    We have examined the incidence of Harvey ras mutations in human squamous cell carcinomas (SCC) of the upper aerodigestive tract using the polymerase chain reaction (PCR) followed by direct sequencing. No mutations were detected at codons 12, 13, 59 or 61 of this gene in any of six papillomas, five erythroplakias, 56 squamous cell carcinomas, and 16 SCC cell lines. Some of the SCC were lymph node metastases (three) or tumours which had recurred following radiotherapy (seven). We conclude that Harvey ras mutations are not a common event in the pathogenesis or recurrence of SCCs from Caucasian subjects, in contrast to the situation with Indian populations (Saranath et al., 1991).

    Full Text Available Pterygium is a common benign lesion of limbus but the pathogenesis are not completely understood. Pterygia have a chronic inflammatory cellular infiltrate and a rich vasculature. Mast cells are a heterogeneous group of multifunctional tissue-resident cells. It has been suggested that mast cells and their products may be responsible for the formation of new blood vessels. We investigated the number and phenotype of mast cells and neovascularization in pterygia specimens and compared with those in normal conjunctival specimensPterygia tissues were obtained during excisional surgery from 32 eyes of 32 consecutive patients. Seventeen of all cases were recurrent pterygia. Superior bulbar conjunctival tissue from the same eye was also sampled as control tissues. The tissue sections were stained with routine hematoxyline-eosin and toluidine blue stain for mast cells. For immunohistochemical studies anti-factor VIII-related antigen, monoclonal anti human mast cell tryptase and chymase were used as an endothelial and mast cell marker.The mean number of mast cells in pterygia was significantly higher than that in the normal conjunctival tissue and microvessel counts was significantly higher than the counts of the controls in both primary and recurrent pterygia. There was no correlation between microvessel numbers and mast cell numbers. There was no phenotypic difference between the mast cells in the ptergyia and those in the normal conjunctival tissues.This study confirms that mast cells are prominent in pterygia and our results suggest that mast cells and angiogenesis are independent factors in the genesis and progress of ptergyium.

    Recently, vitamin D analogues have shown antineoplastic effect in several diseases. Vitamin D analogues exert its effect by interacting with the vitamin D receptor (VDR). Studies of VDR in transitional cell carcinoma (TCC) have not been reported. The purpose of the present study was therefore.......05). Similarly, also tumor grade appeared to be related to the number of cells expressing the receptor. Normal urothlium also expressed VDR but only with low intensity. Our study shows that TCC cells possess the VDR receptor which may make them capable to respond to stimulation with vitamin D, but functional...... studies of vitamin D's effect on TCC cells in vitro are necessary before the efficacy of treatment with vitamin D analogues in TCC can be evaluated in patients....

    Bladder cancer is the second common cancer of the genitourinary system throughout the world and intravesical chemotherapy is usually used to reduce tumour recurrence and progression. Human transitional cell carcinoma (TCC) is an epithelial-like adherent cell line originally established from primary bladder carcinoma. Here we report the effect of mogoltacin, a sesquiterpene coumarin from Ferula badrakema on TCC cells. Mogoltacin was isolated from the fruits of F. badrakema, using silica gel column chromatography and preparative thin layer chromatography. Mogoltacin did not have any significant cytotoxicity effect on neoplastic TCC cells at 16, 32, 64, 128, 200 and 600 microg ml(-1) concentrations. In order to analyse its combination effect, TCC cells were cultured in the presence of various combining concentrations of mogoltacin and vincristine. Cells were then observed for morphological changes (by light microscopy) and cytotoxicity using MTT assay. The effect of mogoltacin on vincristine toxicity was studied after 24, 48 and 72 h of drug administration. The results of MTT assay showed that mogoltacin can significantly enhance the cytotoxicity of vincristine and confirmed the morphological observations. Results revealed that combination of 40 microg ml(-1) vincristine with 16 microg ml(-1) mogoltacin increased the cytotoxicity of vincristine after 48 h by 32.8%.

    Full Text Available Abstract Background Hürthle cell carcinoma is a variant of follicular cell carcinoma of thyroid. It may present as a low-grade tumour or as a more aggressive type. Prognosis depends upon the age of the patient, tumour size, extent of invasion and initial nodal or distant metastasis. Patient and methods The case of Hürthle cell carcinoma is reported in a 79-year-old man who presented with a rapidly increasing lump on the left side of his neck, having had a right hemithyroidectomy for colloid goitre 24-years-ago. Fine needle aspiration cytology confirmed the presence of Hürthle cells, raising the possibility of a Hürthle cell neoplasm. The patient underwent staging and surgery. Histology showed Hürthle cell carcinoma and the patient underwent adjuvant therapy. The literature on Hürthle cell neoplasms is reviewed. Conclusions Fine needle aspiration cytology may recognise Hürthle cell lesion but final diagnosis of carcinoma depends upon histological confirmation of vascular or capsular invasion. Staging and surgery in Hürthle cell carcinoma are similar to follicular carcinoma of thyroid with favourable outcome despite the controversy regarding the histological classification and adjuvant therapy. Elderly patients with Hürthle cell carcinoma need to be made aware of their poorer prognosis and should be offered more radical treatment.

    Objective:To explore the expression of DNA polymerase iota in transitional cell carcinoma cells and tissues; Methods: RT-PCR was applie to detect the expression of polymerase iota in BIU87 and T24 cells, then the expression of polymerase iota was also detected in the same way in transitional cell carcinoma which was derived from clinical bladder carcinoma and renal pelvic carcinoma. Results: The expression of Polt was low in bladder normal membrana mucosa but significantly elevated in transitional cell carcinoma cells. Compared with the expression of polymerase iota in bladder normal mucous membranes, the expression of polymerase iota was significantly increased in transitional cell carcinoma tissue (P<0.01)and associated with the grade of transitional cell carcinoma. Conclusion: The significantly increased expression of polymerase iota may be associated with the generation and development of transitional cell carcinoma, even with its high heterogenicity.

    Large cell neuroendocrine carcinomas of the ampulla of Vater are rare and confer a very poor prognosis despite aggressive therapy. There are few case reports of large cell neuroendocrine carcinomas of the ampulla of Vater in the literature and to date no studies have been done to establish optimal management. We describe a pooled case series from published reports of neuroendocrine carcinomas of the ampulla of Vater including a case which presented to our institution.

    Full Text Available Basal cell carcinoma (BCC remains the most common form of nonmelanoma skin cancer (NMSC in Caucasians, with perhaps as many as 2 million new cases expected to occur in the United States in 2010. Many treatment options, including surgical interventions and nonsurgical alternatives, have been utilized to treat BCC. In this paper, two non-surgical options, imiquimod therapy and photodynamic therapy (PDT, will be discussed. Both modalities have demonstrated acceptable disease control rates, cosmetically superior outcomes, and short-term cost-effectiveness. Further studies evaluating long-term cure rates and long-term cost effectiveness of imiquimod therapy and PDT are needed.

    The combination of renal tuberculosis and renal cancer is rare. The authors report the case of a patient who was followed for multifocal pulmonary, hepatic and renal tuberculosis. The diagnosis of associated renal tumour was raised in the presence of suggestive radiological images. Tumourectomy was performed after tuberculostatic therapy, and histological examination revealed renal cell carcinoma associated with caseo-follicular tuberculous granulomas. The outcome was favourable after a follow-up of 2 years. The objective of this study is to analyse the pathogenesis, diagnostic features and treatment modalities of this exceptional combination.

HCC generally has a more aggressive clinical behavior compared with the other differentiated thyroid cancers, and it is associated with a higher rate of distant metastases. Minimally invasive HCC demonstrates much less aggressive behavior; lesions <4 cm can be treated with thyroid lobectomy alone, and without radioactive iodine (RAI. HCC has been observed to be less iodine-avid compared with other differentiated thyroid cancers; however, recent data have demonstrated improved survival with RAI use in patients with HCC >2 cm and those with nodal and distant metastases. Patients with localized iodine-resistant disease who are not candidates for a wait-and-watch approach can be treated with localized therapies. Systemic therapy is reserved for patients with progressive, widely metastatic HCC. Keywords: thyroid cancer, thyroid nodule, follicular cell carcinoma, Hurthle cell lesion, minimally invasive HCC

    Lung large cell neuroendocrine carcinoma (L-LCNEC) is a rare, aggressive, and difficult-to-treat tumor. It is classified as a neuroendocrine subtype of large cell lung carcinoma (LCLC) belonging to the non-small cell lung cancer (NSCLC) group, but it is also included in the neuroendocrine tumor (NET) group. Most of the available data related to its treatment derive from retrospective analyses or small case series. For patients with L-LCNEC, prognosis is generally very poor. In early stages (I-II-III), surgery is recommended but does not seem to be sufficient. Platinum-based adjuvant chemotherapy may be useful while the role of neoadjuvant chemotherapy is still not well defined. In patients with advanced L-LCNEC, the chemotherapy regimens used in SCLC still remain the standard of treatment, but results are not satisfactory. Due to their peculiar clinical and biological features and the lack of literature data, there is an emerging need for a consensus on the best treatment strategy for L-LCNEC and for the identification of new therapeutic options. In this review, we will discuss the key aspects of L-LCNEC management with the aim to clarify the most controversial issues.

  15. Percutaneous Cryoablation for Renal Cell Carcinoma

    2015-06-01

    Full Text Available Renal cell carcinoma (RCC is the most common type of kidney cancer in adults. Nephron sparing resection (partial nephrectomy has been the “gold standard” for the treatment of resectable disease. With the widespread use of cross sectional imaging techniques, more cases of renal cell cancers are detected at an early stage, i.e. stage 1A or 1B.  This has provided an impetus for expanding the nephron sparing options and especially, percutaneous ablative techniques.  Percutaneous ablation for RCC is now performed as a standard therapeutic nephron-sparing option in patients who are poor candidates for resection or when there is a need to preserve renal function due to comorbid conditions, multiple renal cell carcinomas, and/or heritable renal cancer syndromes. During the last few years, percutaneous cryoablation has been gaining acceptance as a curative treatment option for small renal cancers. Clinical studies to date indicate that cryoablation is a safe and effective therapeutic method with acceptable short and long term outcomes and with a low risk, in the appropriate setting.  In addition it seems to offer some advantages over radio frequency ablation (RFA and other thermal ablation techniques for renal masses.

    Background: Laparoscopic hepatectomy is increasingly being used to treat hepatocellular carcinoma (HCC). How‑ever, few studies have examined the treatment of recurrent HCC in patients who received a prior hepatectomy. The present prospective study compared the clinical efcacy of laparoscopic surgery with conventional open surgery in HCC patients with postoperative tumor recurrence. Methods: We conducted a prospective study of 64 patients, all of whom had undergone open surgery once before, who were diagnosed with recurrent HCC between June 2014 and November 2014. The laparoscopic group (n = 31)underwent laparoscopic hepatectomy, and the control group (n tion time, intraoperative blood loss, surgical margins, postoperative pain scores, postoperative time until the patient= 33) underwent conventional open surgery. Opera‑could walk, anal exsufation time, length of hospital stay, and inpatient costs were compared between the two groups. The patients were followed up for 1 year after surgery, and relapse‑free survival was compared between the two groups. Results: All surgeries were successfully completed. No conversion to open surgery occurred in the laparoscopic group, and no serious postoperative complications occurred in either group. No significant difference in inpatient costs was found between the laparoscopic group and the control group (P = 0.079), but significant differencesbetween the two groups were observed for operation time (116.7 ± 37.5 vs. 148.2 ± 46.7 min, P = 0.031), intraopera‑tive blood loss (117.5 ± 35.5 vs. 265.9 ± 70.3 mL, P = 0.012), postoperative time until the patient could walk (1.6 ± 0.6vs. 2.2 ± 0.8 days, P 0.05) between the patients with contralateral HCC recur‑rence (n = 18) and those with ipsilateral HCC recurrence (n = 13). However, intraoperative blood loss was signifi‑cantly less (97.7 ± 14.0 vs. 186.3 ± 125.6 mL, P = 0.012) and the hospital stay was significantly shorter (4.2 ± 0.7 vs. 6.1 ± 1.7 days, P = 0

    Patients with recurrent or metastatic medullary thyroid carcinoma (MTC) were referred for pretargeted immunoscintigraphy (Affinity Enhancement System; AES) and radioimmunoguided surgery (RIGS). Data collected from 13 patients establish that whole-body AES immunoscintigraphy revealed metastases < 360 mg and RIGS detected micrometastases (5-15 mg). All tissue samples removed by the surgeon were diagnosed by histology and immunohistochemistry of calcitonin to check the accuracy of IS and RIGS results. AES immunoscintigraphy is very sensitive. Of 34 metastases or recurrences detected, 22 had escaped physical examination or conventional imaging. The accuracy of RIGS was 86%, its sensitivity 75%, and its specificity was 90% (n = 208). IS and RIGS detected occult tumors that would have escaped surgery, clearly demonstrating clinical benefit. Serum calcitonin (normal, 10 pg/ml) and carcinoembryonic antigen (normal, 5 ng/ml) of two patients were restored to normal. In patients whose tumors were discovered, progression of their disease was slowed, as evidenced by the large decrease in serum calcitonin and carcinoembryonic antigen, an important prognostic factor. Surgery was canceled in one case where IS detected distant metastases out of surgical reach. Thus, AES immunoscintigraphy and RIGS might be of valuable help for the surgical management of medullary thyroid carcinoma.

    Invasion into the matrix is one of hallmarks of malignant diseases and is the first step for tumor metastasis. Thus, analysis of the molecular mechanisms of invasion is essential to overcome tumor cell invasion. In the present study, we screened for colon carcinoma-specific genes using a cDNA microarray database of colon carcinoma tissues and normal colon tissues, and we found that fermitin family member-1 (FERMT1) is overexpressed in colon carcinoma cells. FRRMT1, FERMT2 and FERMT3 expression was investigated in colon carcinoma cells. Reverse transcription polymerase chain reaction (RT-PCR) analysis revealed that only FERMT1 had cancer cell-specific expression. Protein expression of FERMT1 was confirmed by western blotting and immunohistochemical staining. To address the molecular functions of FERMT genes in colon carcinoma cells, we established FERMT1-, FERMT2- and FERMT3-overexpressing colon carcinoma cells. FERMT1-overexpressing cells exhibited greater invasive ability than did FERMT2- and FERMT3-overexpressing cells. On the other hand, FERMT1-, FERMT2- and FERMT3-overexpressing cells exhibited enhancement of cell growth. Taken together, the results of this study indicate that FERMT1 is expressed specifically in colon carcinoma cells, and has roles in matrix invasion and cell growth. These findings indicate that FERMT1 is a potential molecular target for cancer therapy.

  20. A scoring model based on neutrophil to lymphocyte ratio predicts recurrence of HBV-associated hepatocellular carcinoma after liver transplantation.

    Guo-Ying Wang

    Full Text Available BACKGROUND: Neutrophil to lymphocyte ratio (NLR has been proposed to predict prognosis of hepatocellular carcinoma (HCC. However, the cut-off values are empirical. We determined the optimal cut-off value to predict HCC recurrence after liver transplantation (LT and further established a scoring model based on NLR. METHODOLOGY/PRINCIPAL FINDINGS: We analyzed the outcome of 101 HBV-associated HCC patients undergoing LT. Preoperative risk factors for tumor recurrence were evaluated by univariate analysis. By using ROC analysis, NLR≥3 was considered elevated. The disease-free survival (DFS and overall survival (OS for patients with high NLR was significantly worse than that for patients with normal NLR (the 5-year DFS and OS of 28.5% and 19.5% vs. 64.9% and 61.8%, respectively; P5 cm, tumor number >3, macrovascular invasion, AFP≥400 µg/L, NLR≥3, and HBV-DNA level >5 log10 copies/mL were preoperative predictors of DFS. Cox regression analysis showed macrovascular invasion, tumor number, and high NLR were independent prognostic factors. We then established a preoperative prognostic score based on multivariate analysis. Each factor was given a score of 1. Area under the ROC curve of the score was 0.781. All nine patients with score 3 developed recurrence within 6 months after LT. Of 71 patients without vascular invasion, three patients with both tumor number >3 and NLR≥3 developed recurrence within 14 months after LT while the 5-year DFS and OS for patients with a score of 0 or 1 were 68.1% and 62.8%, respectively. CONCLUSIONS/SIGNIFICANCE: Preoperative elevated NLR significantly increases the risk of recurrence in patients underwent LT for HCC. Patients with both NLR≥3 and tumor number >3 are not a good indication for LT. Our score model may aid in the selection of patients that would most benefit from transplantation for HCC.

    Full Text Available Nonmelanoma skin cancers (squamous cell and basal cell carcinomas occur at an epidemic rate in many countries with the worldwide incidence increasing. The sun-exposed head and neck are the most frequent sites for these cancers to arise and in most patients diagnosed with a cutaneous squamous cell carcinoma, local treatment is usually curative. However, a subset is diagnosed with a high-risk cutaneous squamous cell carcinoma. High-risk factors include size (> 2 cm, thickness/depth of invasion (> 4 mm, recurrent lesions, the presence of perineural invasion, location near the parotid gland, and immunosuppression. These patients have a higher risk (> 10–20% of developing metastases to regional lymph nodes (often parotid nodes, and in some cases also of experiencing local morbidity (perineural invasion, based on unfavourable primary lesion and patient factors. Despite treatment, many patients developing metastatic cutaneous squamous cell carcinoma experience mortality and morbidity usually as a consequence of uncontrolled metastatic nodal disease. It is therefore important that clinicians treating nonmelanoma skin cancers have an understanding and awareness of these high-risk patients. The aim of this article is to discuss the factors that define a high-risk patient and to present some of the issues pertinent to their management.

    Intraoperative neuropathology of glioma recurrence represents significant visual challenges to pathologists as they carry significant clinical implications. For example, rendering a diagnosis of recurrent glioma can help the surgeon decide to perform more aggressive resection if surgically appropriate. In addition, the success of recent clinical trials for intraoperative administration of therapies, such as inoculation with oncolytic viruses, may suggest that refinement of the intraoperative diagnosis during neurosurgery is an emerging need for pathologists. Typically, these diagnoses require rapid/STAT processing lasting only 20-30 minutes after receipt from neurosurgery. In this relatively short time frame, only dyes, such as hematoxylin and eosin (H and E), can be implemented. The visual challenge lies in the fact that these patients have undergone chemotherapy and radiation, both of which induce cytological atypia in astrocytes, and pathologists are unable to implement helpful biomarkers in their diagnoses. Therefore, there is a need to help pathologists differentiate between astrocytes that are cytologically atypical due to treatment versus infiltrating, recurrent, neoplastic astrocytes. This study focuses on classification of neoplastic versus non-neoplastic astrocytes with the long term goal of providing a better neuropathological computer-aided consultation via classification of cells into reactive gliosis versus recurrent glioma. We present a method to detect cells in H and E stained digitized slides of intraoperative cytologic preparations. The method uses a combination of the `value' component of the HSV color space and `b*' component of the CIE L*a*b* color space to create an enhanced image that suppresses the background while revealing cells on an image. A composite image is formed based on the morphological closing of the hue-luminance combined image. Geometrical and textural features extracted from Discrete Wavelet Frames and combined to classify

    Hürthle cell carcinoma is a rare variant of differentiated thyroid cancer that occasionally forms distant metastases. However, even in the presence of metastases, patients with Hürthle cell carcinoma have a relatively good prognosis. There are few reports of Hürthle cell carcinoma metastases to the vertebral column, and none describing aggressive resection of spinal metastases. Here, we report a 68-year-old woman with a solitary metastasis of Hürthle cell carcinoma to the T1 vertebral body causing severe kyphotic deformity, myelopathy, and pain. The patient was treated with aggressive excisional decompression of the spinal cord and T1 vertebral body resection from an entirely posterior approach. Reconstruction and stabilization of the anterior spine was accomplished with a transforaminal lumbar interbody fusion allograft spacer and posterior instrumentation. We discuss aspects of the diagnosis, management, patient selection, and surgical treatment of metastatic Hürthle cell carcinoma in reference to the literature.

    Clear cell carcinoma (CCC) is a rare low-grade carcinoma that represents only 1% to 2% of all salivary glands tumors. The finding of a clear cell tumor in a parotid gland involves the necessity of differential diagnosis between primary clear cell parotid tumors and metastases, mainly from kidney. The biological behavior is not very aggressive and development, which is very slow, is usually asymptomatic and indeed, the tumor often reaches considerable dimensions before being diagnosed. The treatment of choice is the surgical excision. There are rare cases of local recurrence and distant metastases. The aim of this article is to report a primary CCC in the parotid gland that microscopically closely resembled a metastatic CCC of renal origin, making microscopic differentiation difficult.

    Full Text Available Reena Kabaria, Zachary Klaassen, Martha K Terris Department of Surgery, Section of Urology, Augusta University, Augusta, GA, USA Abstract: This review provides an overview of the incidence of renal cell carcinoma (RCC and a summary of the most commonly associated risk factors. A literature review was performed with a focus on recent studies with a high level of evidence (large prospective cohort studies and meta-analyses. The incidence rate of RCC varies globally, with the rate rising rapidly in more developed regions, demonstrating the effects of increased use of diagnostic imaging and prevalence of modifiable risk factors. Based on the current evidence, cigarette smoking, obesity, and hypertension are the most well-established risk factors for sporadic RCC worldwide. Acquired cystic kidney disease is also a significant risk factor, specifically in dialysis patients. There is increasing evidence for an inverse association between RCC risk and moderate alcohol consumption. Certain analgesics and occupational exposure have been linked to an increased risk of RCC, although data are limited. Diets rich in fruits and vegetables may provide a protective effect.

    Despite the radical surgical resection performed in patients with colorectal carcinoma, there is a high rate of tumor recurrence. Over an observation period of 3 years, 18% of the patients in our collective suffered a tumor relapse with local or distinct metastases after initial R0-resection. Some evidence suggests that this may be due to suppression of anti-tumor responses, a phenomenon that might be attributed to regulatory T cells. The aim of our study was to investigate the tumor-specific immune response depending on the UICC stage of patients with colorectal cancer. The cellular immune responses against defined antigens that are overexpressed in most of the patients with colorectal cancer were characterized. For this purpose, the tumor suppressor gene, p53, was chosen as the tumor-associated antigen that exhibits mutations and overexpression in up to 60% of colorectal carcinoma. We observed that p53 induced both IFN-gamma and IL-10 secretion. The predominance of IL-10 production indicated that regulatory T cells directly participate in modulating the anti-tumor immune response. IL-10 levels in the blood as well as the expression of regulatory T-cell specific genes at the tumor site correlate with the UICC stage of the disease. These results may provide an explanation for the poor prognosis and increased recurrence rate in patients with advanced carcinoma.

    Ten to twenty percent of the hepatocellular carcinoma (HCC) patients fulfilling the Milan criteria (MC) recurred within three years after orthotopic liver transplantation (OLT). We therefore utilize a training cohort to develop an improved prognostic model for predicting the recurrence in these patients. By univariate and multivariate analysis, AFP level [cut-off value: 321 ng/mL, area under the curve (AUC) = 0.724, 95% confidence interval (CI) = 0.604–0.843, P < 0.001] and cytokeratin-19 (CK19) and glypican-3 (GPC3) expression pattern from nine putative prognostic factors were entered in risk factor scoring model to conjecture the tumor recurrence. In the training cohort, the AUC value of the model was 0.767 (95% CI = 0.645–0.890, P < 0.001), which was the highest among all the elements. The model’s performance was then assessed using a validation cohort. In the validation cohort, the AUC value of the model was 0.843 (95% CI = 0.720−0.966, P < 0.001) which was higher than any other elements. The results indicated that model had high performance with good discrimination ability and significantly improved the predictive capacity for the recurrence of HCC patients within MC after OLT.

    AIM:To evaluate the impact of obesity on the postoperative outcome after hepatic resection in patients with hepatocellular carcinoma (HCC).METHODS:Data from 328 consecutive patients with primary HCC and 60 patients with recurrent HCC were studied.We compared the surgical outcomes between the non-obese group (body mass index:BHI<25 kg/m2)and the obese group(BHI≥25 kg/m2).RESULTS:Following curative hepatectomy in patients with primary HCC,the incidence of postoperative complications and the long-term prognosis in the nonobese group(n=240) were comparable to those in the obese group(n=88).Among patients with recurrent HCC,the incidence of postoperative complications after repeat hepatectomy was not significantly different between the non-obese group(n=44) and the obese group(n=16).However,patients in the obese group showed a significantly poorer long-term prognosis than those in the non-obese group(P<0.05,five-year survival rate;51.9% and 92.0%,respectively).CONCLUSION:Obesity alone may not have an adverse effect on the surgical outcomes of patients with primary HCC.However,greater caution seems to be required when planning a repeat hepatectomy for obese patients with recurrent HCC.

    Hepatocyte nuclear factor 1-beta (HNF1β) has recently emerged as a relatively sensitive and specific marker for ovarian clear cell carcinoma. The purpose of this study is to assess the diagnostic utility of this marker for endometrial clear cell carcinoma. Immunohistochemical analysis was performed on 75 endometrial tissues using a goat polyclonal antibody raised against a peptide mapping at the C-terminus of human HNF1β protein. The 75 cases included 15 clear cell carcinomas, 20 endometrioid carcinomas, 15 endometrial serous carcinomas/uterine papillary serous carcinomas, 20 cases of normal endometrium, 2 cases of clear cell metaplasia, and 3 cases of Arias Stella reaction. Staining interpretations were based on a semiquantitative scoring system, a 0 to 12+ continuous numerical scale that was derived by multiplying the extent of staining (0 to 4+ scale) by the intensity of staining (0 to 3+ scale) for each case. HNF1β expression was found to be present in a wide spectrum of tissues. Twenty-seven (54%) of the 50 carcinomas displayed at least focal nuclear HNF1β expression, including 11 (73%) of 15, 9 (60%) of 15, and 7 (35%) of 20 clear cell, serous, and endometrioid carcinomas, respectively. The average nuclear staining scores for clear cell carcinomas, endometrioid carcinomas, and serous carcinomas were 5.2, 1.4, and 4.1, respectively. Clear cell carcinomas and endometrioid carcinomas displayed statistically significant differences regarding their nuclear staining scores (P = 0.0027), but clear cell carcinomas and endometrial serous carcinomas did not (P = 0.45). The calculated sensitivity of any nuclear HNF1β expression in classifying a carcinoma as being of the clear cell histotype was 73%, whereas the specificity was 54%. Nineteen of 20 normal endometrium samples displayed at least focal nuclear expression of HNF1β, and this expression was often diffuse. The 5 cases of benign histologic mimics of clear cell carcinomas (Arias Stella reaction and clear

All of the patients received curative surgery and the clinical follow-up was 60 months. The clinical and cytometric parameters were evaluated in order to predict the patients’ outcome. The presence of tumoural recurrence and the tumoural stage showed statistical significance associated with survival. The multivariant analysis reveals radiotherapy (p = 0.004 as protective variable and the high S-phase fraction (SPF (p = 0.001 and stage IIIA (p = 0.012 as risk factors. The SPF appears as an independent prognostic factor for overall survival time.

    Squamoid eccrine ductal carcinoma is an eccrine carcinoma subtype, and only twelve cases have been reported until now. It is a rare tumor and its histopathological diagnosis is difficult. Almost half of patients are misdiagnosed as squamous cell carcinoma by the incisional biopsy. We report the thirteenth case of squamoid eccrine ductal carcinoma. Female patient, 72 years old, in the last 6 months presenting erythematous, keratotic and ulcerated papules on the nose. The incisional biopsy diagnosed squamoid eccrine ductal carcinoma. After excision, histopathology revealed positive margins. A wideningmargins surgery and grafting were performed, which again resulted in positive margins. The patient was then referred for radiotherapy. After 25 sessions, the injury reappeared. After another surgery, although the intraoperative biopsy showed free surgical margins, the product of resection revealed persistent lesion. Distinction between squamoid eccrine ductal carcinoma and squamous cell carcinoma is important because of the more aggressive nature of the first, which requires wider margins surgery to avoid recurrence.

    2014-01-01

    Full Text Available Background: Loss of expression of cadherins by promoter hypermethylation has been described in many epithelial cancers, and it may play a role in tumor cell invasion and metastasis. Previously, we reported that E-cadherin gene is frequently methylated in epithelial ovarian cancer. Aim: The aim of this study was to compare the promoter hypermethylation of H-cadherin gene in ovarian epithelial neoplasms to better understand the role of epigenetic silencing in carcinogenesis. Materials and Methods: We examined the promoter methylation of the H-cadherin gene in 134 epithelial ovarian carcinomas (EOC, 23 low malignant potential (LMP tumors, 26 benign cystadenomas and 15 normal ovarian tissues. Methylation was investigated by methylation specific polymerase chain reaction (MSP and the results confirmed by bisulfite DNA sequencing. Relative gene expression of H-cadherin was done using quantitative reverse transcriptase PCR on 51 EOC cases, 9 LMP tumors, 7 benign cystadenomas with 5 normal ovarian tissues. Results: Aberrant methylation of H-cadherin was present in 20 of 134 (15% carcinoma cases, 2 of 23 (09% LMP tumors and 1 of 26 (4% benign cystadenomas. No methylation was observed in any of the normal ovarian tissues. The mRNA expression level of H-cadherin was significantly down-regulated in EOC and LMP tumors than the corresponding normal tissues, whereas the expression level was normal in benign cystadenomas. A significant correlation of H-cadherin promoter methylation was observed with reduced gene expression in EOC. The prevalence of H-cadherin methylation was associated significantly with stage, histopathological grade, and menopausal status of the patient. H-cadherin methylation also had significant association with recurrence and differentiation of tumor. Conclusion: Our findings suggest an association between H-cadherin methylation, tumor progression and recurrence in EOC.

    AIM: The survival time of patients with hepatocellular carcinoma (HCC) after resection is hard to predict. Both residual liver function and tumor extension factors should be considered. A new scoring system has recently been proposed by the Cancer of the Liver Italian Program (CLIP).CUP score was confirmed to be one of the best ways to stage patients with HCC. To our knowledge, however, the literature concerning the correlation between CLIP score and prognosis for patients with HCC after resection was not pubhshed. The aim of this study is to evaluate the recurrence and prognostic value of CLIP score for the patients with HCC after resection.METHODS: A retrospective survey was carried out in 174patients undergoing resection of HCC from January 1986 toJune 1998. Six patients who died in the hospital afteroperation and 11 patients with the recurrence of the diseasewere excluded at 1 month after hepatectomy. By the end ofJune 2001, 4 patients were lost and 153 patients with curativeresection have been followed up for at least three years.Among 153 patients, 115 developed intrahepatic recurrenceand 10 developed extrahepatic recurrence, whereas the other28 remained free of recurrence. Recurrences were classifiedinto early ( < / = 3 year) and late ( > 3 year) recurrence. TheCLIP score included the parameters involved in the Child-Pugh stage (0-2), plus macroscopic tumor morphology (0-2), AFP levels (0-1), and the presence or absence of portalthrombosis (0-1)o By contrast, portal vein thrombosis wasdefined as the presence of tumor emboli within vascularchannel analyzed by microscopic examination in this study.Risk factors for recurrence and prognostic factors forsurvival in each group were analyzed by the chi-square test,the Kaplan-Meier estimation and the COX proportionalhazards model respectively.RESULTS: The 1-, 3-, 5-, 7-, andl0-year disease-free survivalrates after curative resection of HCC were 57.2 %、 28.3 %、23.5 %、 18.8 % and 17.8 %, respectively.

    Spindle cell carcinoma is a malignancy of epithelial origin often mimicking its mesenchymal counterpart thus posing a diagnostic challenge. It is a rare biphasic malignant tumour mostly encountered in the upper aerodigestive tract. The chief differential diagnoses of spindle cell carcinoma are true superficial sarcomas and they especially need to be differentiated from fibrosarcoma. This presentation reports a spindle cell carcinoma of the gingiva and highlights the difficulties encountered in the diagnosis. It also emphasizes the importance of accurate and thorough diagnosis of malignant spindle cell lesions to determine the appropriate therapeutic modality.

    2013-12-01

    Full Text Available The molecular pathogenesis of thymomas and thymic carcinomas (TCs is poorly understood and results of adjuvant therapy are unsatisfactory in case of metastatic disease and tumor recurrence. For these clinical settings, novel therapeutic strategies are urgently needed. Recently, limited sequencing efforts revealed that a broad spectrum of genes that play key roles in various common cancers are rarely affected in thymomas and thymic carcinomas, suggesting that other oncogenic principles might be important. This made us re-analyze historic expression data obtained in a spectrum of thymomas and thymic squamous cell carcinomas (TSCC with a custom made cDNA microarray. By cluster analysis, different anti-apoptotic signatures were detected in type B3 thymoma and TSCC, including overexpression of BIRC3 in TSCCs. This was confirmed by qRT-PCR in the original and an independent validation set of tumors. In contrast to several other cancer cell lines, the BIRC3-positive TSCC cell line, 1889c showed spontaneous apoptosis after BIRC3 knock-down. Targeting apoptosis genes is worth testing as therapeutic principle in TSCC.

    2012-01-01

    Full Text Available Background: Current treatments for hypercalcemia caused by lung cell carcinomas producing parathyroid hormone-related peptide (PTH-rp have limited efficacy, probably because of their lack of effect on PTH-rp secretion. In this case study we explored the efficacy of the calcimimetic cinacalcet as suppressor of PTH-rp production. Patient: A 57-year-old male with severe and recurrent hypercalcemia induced by a PTH-rp-producing squamous cell lung carcinoma, stage cT4N3M1b, poorly responding to standard treatments. Results: Serum PTH-rp levels were not affected by saline, calcitonin or zoledronate. PTH-rp decreased during chemotherapy and cinacalcet monotherapy. The combination of chemotherapy plus cinacalcet was most effective in rapidly reducing serum calcium and PTH-rp. Conclusion: This case study is the first to suggest that cinacalcet may be of value in some cases of PTH-rp-dependent hypercalcemia. Corroborative evidence is needed.

    Background Current treatments for hypercalcemia caused by lung cell carcinomas producing parathyroid hormone-related peptide (PTH-rp) have limited efficacy, probably because of their lack of effect on PTH-rp secretion. In this case study we explored the efficacy of the calcimimetic cinacalcet as suppressor of PTH-rp production. Patient A 57-year-old male with severe and recurrent hypercalcemia induced by a PTH-rp-producing squamous cell lung carcinoma, stage cT4N3M1b, poorly responding to standard treatments. Results Serum PTH-rp levels were not affected by saline, calcitonin or zoledronate. PTH-rp decreased during chemotherapy and cinacalcet monotherapy. The combination of chemotherapy plus cinacalcet was most effective in rapidly reducing serum calcium and PTH-rp. Conclusion This case study is the first to suggest that cinacalcet may be of value in some cases of PTH-rp-dependent hypercalcemia. Corroborative evidence is needed. PMID:22379470

    Squamous cells carcinoma (SCC) is the second most frequent of the keratinocyte-derived malignancies after basal cell carcinoma and is associated with a significant psychosocial and economic burden for both the patient himself and society. Reported risk factors for the malignant transformation of keratinocytes and development of SCC include ultraviolet light exposure, followed by chronic scarring and inflammation, exposure to chemical compounds (arsenic, insecticides, and pesticides), and immune-suppression. Despite various available treatment methods and recent advances in noninvasive or minimal invasive diagnostic techniques, the risk recurrence and metastasis are far from being negligible, even in patients with negative histological margins and lymph nodes. Analyzing normal, dysplastic, and malignant keratinocyte proteome holds special promise for novel biomarker discovery in SCC that could be used in the future for early detection, risk assessment, tumor monitoring, and development of targeted therapeutic strategies.

    Most Merkel cell carcinomas display pure neuroendocrine differentiation (pure Merkel cell carcinoma), whereas a minority show combined neuroendocrine and nonneuroendocrine elements (combined Merkel cell carcinoma). Recent identification of Merkel cell polyomavirus DNA and Merkel cell polyomavirus large T antigen expression in a proportion of Merkel cell carcinomas has suggested viral-induced oncogenesis. To date, Merkel cell polyomavirus immunohistochemistry has shown an absence of viral large T antigen expression in combined Merkel cell carcinoma as well as select non-Merkel cell carcinoma cutaneous lesions and visceral neuroendocrine tumors. In our series, we aimed to further characterize the frequency and pattern of Merkel cell polyomavirus large T antigen expression by CM2B4 immunohistochemistry in primary and metastatic Merkel cell carcinoma (pure Merkel cell carcinoma and combined Merkel cell carcinoma) and various non-Merkel cell carcinoma lesions from patients with Merkel cell carcinoma, patients without Merkel cell carcinoma, and individuals with altered immune function. Merkel cell polyomavirus large T antigen was detected in 17 (63%) of 27 pure Merkel cell carcinomas and absent in all 15 (0%) combined Merkel cell carcinomas. Furthermore, complete concordance (100%) of Merkel cell polyomavirus large T antigen expression was observed in 10 cases of primary Merkel cell carcinoma and subsequent tumor metastases. We also evaluated 70 non-Merkel cell carcinoma lesions including 15 cases each of pulmonary and gastrointestinal neuroendocrine tumors. All 70 non-Merkel cell carcinoma lesions were negative for Merkel cell polyomavirus by CM2B4 immunohistochemistry, irrespective of any known Merkel cell carcinoma diagnosis and immune status. In summary, our identification of Merkel cell polyomavirus large T antigen expression in a subset of Merkel cell carcinoma and lack of findings in combined Merkel cell carcinomas and non-Merkel cell carcinoma lesions concur with

    Background Primary small cell carcinoma of the esophagus is rare. Although surgery is successful in eradicating local tumor, the five-year survival rate of patients with primary small cell carcinoma of the esophagus after resection is lower than that of patients with primary squamous cell carcinoma of the esophagus. The purpose of this study was to analyze the clinical manifestations, pathological features and treatment of primary small cell carcinoma of the esophagus.Methods A total of 73 patients with primary small cell carcinoma of the esophagus who had been treated by surgery from 1984 to 2003 were analyzed retrospectively.Results In this series, the overall resection rate was 94.5% (69/73), the radical resection rate 89.0% (65/73) and the operative mortality 1.4% (1/73). The 1-, 3- and 5-year survival rates of patients were 50.7%, 13.7% and 8.2%,respectively.Conclusions Primary small cell carcinoma of the esophagus is rare with a poor prognosis. Surgical resection is the leading method for patients with stage Ⅰ or Ⅱ primary small cell carcinoma of the esophagus. Postoperative chemotherapy is beneficial to these patients. The patients of stage Ⅲ or Ⅳ should be given chemotherapy and radiation therapy.

    Merkel cell carcinoma (MCC) is an aggressive poorly differentiated neuroendocrine cutaneous carcinoma associated with older age, immunodeficiency and Merkel cell polyomavirus (MCPyV) integrated within malignant cells. The presence of intra-tumoural CD8+ lymphocytes reportedly predicts better MCC-specific survival. In this study, the distribution of inflammatory cells and properties of CD8+ T lymphocytes within 20 primary MCC specimens were characterised using immunohistochemistry and multicolour immunofluorescent staining coupled to confocal microscopy. CD8+ cells and CD68+ macrophages were identified in 19/20 primary MCC. CD20+ B cells were present in 5/10, CD4+ cells in 10/10 and FoxP3+ cells in 7/10 specimens. Only two specimens had almost no inflammatory cells. Within specimens, inflammatory cells followed the same patchy distribution, focused at the edge of sheets and nodules and, in some cases, more intense in trabecular areas. CD8+ cells were outside vessels on the edge of tumour. Those few within malignant sheets typically lined up in fine septa not contacting MCC cells expressing MCPyV large T antigen. The homeostatic chemokine CXCL12 was expressed outside malignant nodules whereas its receptor CXCR4 was identified within tumour but not on CD8+ cells. CD8+ cells lacked CXCR3 and granzyme B expression irrespective of location within stroma versus malignant nodules or of the intensity of the intra-tumoural infiltrate. In summary, diverse inflammatory cells were organised around the margin of malignant deposits suggesting response to aberrant signaling, but were unable to penetrate the tumour microenvironment itself to enable an immune response against malignant cells or their polyomavirus.

    Most penile cancers are squamous cell carcinoma (SCC) originating in the epithelium covering glans, coronal sulcus, and foreskin. Several histologic subtypes have been described, each with distinctive clinicopathologic and outcome features. The most common subtype is the usual SCC, representing one half to two thirds of penile carcinomas. Penile verruciform tumors encompass verrucous, warty (condylomatous), and papillary, not otherwise specified, carcinomas. As a group, verruciform tumors are low grade, with low metastatic and mortality rates. In contrast, basaloid and sarcomatoid carcinomas are among the most aggressive penile tumors. Other SCC variants, such as carcinoma cuniculatum and pseudohyperplastic, adenosquamous and acantholytic carcinomas, are rare. The most relevant clinicopathologic and outcome features are outlined for each of these SCC subtypes, and an algorithm that might aid the pathologist in the histologic classification is presented. In addition, recommendations for handling penile cancer specimens, frozen section specimens, and pathology reports are provided.

    Full Text Available Abstract Background Novel therapies are necessary to improve outcomes for patients with squamous cell carcinomas (SCC of the head and neck. Historically, vaccinia virus was administered widely to humans as a vaccine and led to the eradication of smallpox. We examined the therapeutic effects of an attenuated, replication-competent vaccinia virus (GLV-1h68 as an oncolytic agent against a panel of six human head and neck SCC cell lines. Results All six cell lines supported viral transgene expression (β-galactosidase, green fluorescent protein, and luciferase as early as 6 hours after viral exposure. Efficient transgene expression and viral replication (>150-fold titer increase over 72 hrs were observed in four of the cell lines. At a multiplicity of infection (MOI of 1, GLV-1h68 was highly cytotoxic to the four cell lines, resulting in ≥ 90% cytotoxicity over 6 days, and the remaining two cell lines exhibited >45% cytotoxicity. Even at a very low MOI of 0.01, three cell lines still demonstrated >60% cell death over 6 days. A single injection of GLV-1h68 (5 × 106 pfu intratumorally into MSKQLL2 xenografts in mice exhibited localized intratumoral luciferase activity peaking at days 2–4, with gradual resolution over 10 days and no evidence of spread to normal organs. Treated animals exhibited near-complete tumor regression over a 24-day period without any observed toxicity, while control animals demonstrated rapid tumor progression. Conclusion These results demonstrate significant oncolytic efficacy by an attenuated vaccinia virus for infecting and lysing head and neck SCC both in vitro and in vivo, and support its continued investigation in future clinical trials.

    Renal cell carcinoma (RCC) is a metabolic disease, being characterized by the dysregulation of metabolic pathways involved in oxygen sensing (VHL/HIF pathway alterations and the subsequent up-regulation of HIF-responsive genes such as VEGF, PDGF, EGF, and glucose transporters GLUT1 and GLUT4, which justify the RCC reliance on aerobic glycolysis), energy sensing (fumarate hydratase-deficient, succinate dehydrogenase-deficient RCC, mutations of HGF/MET pathway resulting in the metabolic Warburg shift marked by RCC increased dependence on aerobic glycolysis and the pentose phosphate shunt, augmented lipogenesis, and reduced AMPK and Krebs cycle activity) and/or nutrient sensing cascade (deregulation of AMPK-TSC1/2-mTOR and PI3K-Akt-mTOR pathways). We analyzed the key metabolic abnormalities underlying RCC carcinogenesis, highlighting those altered pathways that may represent potential targets for the development of more effective therapeutic strategies.

    This review provides an overview of the incidence of renal cell carcinoma (RCC) and a summary of the most commonly associated risk factors. A literature review was performed with a focus on recent studies with a high level of evidence (large prospective cohort studies and meta-analyses). The incidence rate of RCC varies globally, with the rate rising rapidly in more developed regions, demonstrating the effects of increased use of diagnostic imaging and prevalence of modifiable risk factors. Based on the current evidence, cigarette smoking, obesity, and hypertension are the most well-established risk factors for sporadic RCC worldwide. Acquired cystic kidney disease is also a significant risk factor, specifically in dialysis patients. There is increasing evidence for an inverse association between RCC risk and moderate alcohol consumption. Certain analgesics and occupational exposure have been linked to an increased risk of RCC, although data are limited. Diets rich in fruits and vegetables may provide a protective effect.

    Recent developments in chemotherapy have resulted in several new drug treatments for metastatic renal cell carcinoma (RCC). These therapies have shown improved progression-free survival and are applicable to many more patients than the conventional cytokine-based treatments for metastatic RCC. Consequently imaging is playing a greater part in the management of such patients. Computed tomography (CT) remains the primary imaging modality with other imaging modalities playing a supplementary role. CT is used in the diagnosis and staging of metastatic RCC. It is used in the follow-up of patients after nephrectomy, in assessing the extent of metastatic disease, and in evaluating response to treatment. This review looks at the role of CT in patients with metastatic RCC and describes the appearances of metastatic RCC before and following systemic therapy.

    Tuberculosis is still a significant problem in developing countries. Cutaneous forms of tuberculosis account for approximately 10% of all cases of extrapulmonary tuberculosis. Cutaneous tuberculosis may be because of true infection with Mycobacterium tuberculosis or because of tuberculids. Tuberculids are immunological reactions to haematogenously spread antigenic components of M. tuberculosis. True cutaneous tuberculosis may be because of inoculation or haematogenous spread of M. tuberculosis to the skin. Lupus vulgaris is the commonest form of true cutaneous tuberculosis. Other forms of true cutaneous tuberculosis are tuberculous chancre, tuberculosis verrucosa cutis, scrofuloderma, periorificial tuberculosis and miliary tuberculosis of the skin. Lupus vulgaris is usually chronic and progressive. It occurs in patients with moderate to high immunity against M. tuberculosis as evidenced by strongly positive tuberculin test. Long-standing cases of lupus vulgaris may be complicated by squamous cell carcinoma (SCC). We describe a patient who had undiagnosed lupus vulgaris for 35 years until she developed SCC on the lesion of lupus vulgaris.

    Massive upper gastrointestinal bleeding due to malignancy is relatively uncommon and the duodenum is the least frequently involved site. Duodenal metastasis is rare in renal cell carcinoma (RCC) and early detection, especially in case of a solitary mass, helps in planning further therapy. We report a case of intractable upper gastrointestinal bleeding from metastatic RCC to the duodenum. The patient presented with melena and anemia, 13 years after nephrectomy for RCC. On esophagogastroduodenoscopy, a submucosal mass was noted in the duodenum, biopsies of which revealed metastatic RCC. In conclusion, metastasis from RCC should be considered in nephrectomized patients presenting with gastrointestinal symptoms and a complete evaluation, especially endoscopic examination followed by biopsy, is suggested.

    Full Text Available Abstract Background The head and neck/oral squamous cell carcinoma (HNOSCC is a diverse group of cancers, which develop from many different anatomic sites and are associated with different risk factors and genetic characteristics. The oral tongue squamous cell carcinoma (OTSCC is one of the most common types of HNOSCC. It is significantly more aggressive than other forms of HNOSCC, in terms of local invasion and spread. In this study, we aim to identify specific transcriptomic signatures that associated with OTSCC. Results Genome-wide transcriptomic profiles were obtained for 53 primary OTSCCs and 22 matching normal tissues. Genes that exhibit statistically significant differences in expression between OTSCCs and normal were identified. These include up-regulated genes (MMP1, MMP10, MMP3, MMP12, PTHLH, INHBA, LAMC2, IL8, KRT17, COL1A2, IFI6, ISG15, PLAU, GREM1, MMP9, IFI44, CXCL1, and down-regulated genes (KRT4, MAL, CRNN, SCEL, CRISP3, SPINK5, CLCA4, ADH1B, P11, TGM3, RHCG, PPP1R3C, CEACAM7, HPGD, CFD, ABCA8, CLU, CYP3A5. The expressional difference of IL8 and MMP9 were further validated by real-time quantitative RT-PCR and immunohistochemistry. The Gene Ontology analysis suggested a number of altered biological processes in OTSCCs, including enhancements in phosphate transport, collagen catabolism, I-kappaB kinase/NF-kappaB signaling cascade, extracellular matrix organization and biogenesis, chemotaxis, as well as suppressions of superoxide release, hydrogen peroxide metabolism, cellular response to hydrogen peroxide, keratinization, and keratinocyte differentiation in OTSCCs. Conclusion In summary, our study provided a transcriptomic signature for OTSCC that may lead to a diagnosis or screen tool and provide the foundation for further functional validation of these specific candidate genes for OTSCC.

    Introduction: Positron emission tomography/computed tomography (PET-CT) is very sensitive for diagnosis of recurrent NSCLC and has a significant impact on change of management. Preliminary data suggest superiority of PET-CT comparing to CT alone for lung cancer restaging. Materials and methods: This is a retrospective study which aim is to validate usage of PET-CT in suspected non-small cell lung carcinoma recurrence and its impact on further patient management. Total number of 31 patients with non-small cell lung carcinoma and uncertain diagnosis of recurrent disease or its extent after routine clinical and CT work-up were enrolled in this study. Discussion: We found in our study that PET-CT diagnosed recurrent disease in 65% of patients who were previously presented with an indeterminante CT. In 85% of patients there were change in further management. Conclusion: We suggest that PET should be performed on patients who have suspected relapse after potentially curative treatment, particularly if active treatment is being considered. PET-CT improved the diagnosis of recurrent NSCLC and this resulted in a significant impact and change in further patient management. PMID:27708496

    Aim: The causative role of human papillomavirus (HPV) has been established into the aetiology of oral squamous cell carcinoma (OSCC). Some authors believe that HPV can determinate the prognosis and module treatment response from this kind of malignancies.Methods: Articles published in the last 10 years, focusing on the role of HPV in the development, molecular biology, prognosis and treatment of OSCC were reviewed.Results: Thirty-nine articles from 252 were selected, highlighting 4 meta-analysis, 3 prospective and 2 retrospective studies. According to its role in the development of cervical cancer, HPV is classified into a high risk for malignant lesions subtype and a low-grade malignant lesions subtype. Epidemiology and prevalence of HPV varies according to the published data: large studies tend to have lower rates of HPV (< 50%) than smaller ones (0-100%). Interestingly, HPV+ patients are usually diagnosed at a younger age, mainly those with oropharyngeal tumours. There is a predilection for the oropharynx and Waldeyer ring tumours. Regarding prognosis, OSCC HPV+ patients tend to have better outcome and treatment response.Conclusion: HPV divides OSCC in two types of tumours with different prognostic and therapeutic implications, with increased survival, better treatment response rates and lower risk of death and recurrences.

    Squamous cell carcinoma of the nasal planum was diagnosed in 17 dogs over a period of 11 years. Ulceration, bleeding and sneezing were the most common clinical signs. One dog had cytological evidence of metastasis to the local lymph node. The dogs were treated by surgical resection, fractionated megavoltage irradiation, or a combination of the two. Surgical resection gave the most favourable results; four of six dogs were cured but a recurrence of the tumour was predicted in the other two on the basis of incomplete or marginal resection. Radiotherapy alone was not as effective; one of four dogs was cured, and the tumour recurred in the others within 24 weeks (median eight weeks). Combined surgical resection and radiotherapy did not produce a cure in any of the seven remaining dogs, and the tumour recurred within 12 weeks (median nine weeks). Three dogs had cytological evidence of lymph node metastasis when the tumour recurred. The dogs' prognosis was adversely affected by the interval between their initial examination and treatment, but there was no apparent association between the histological grade of the tumour and the clinical outcome.

    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.

    We report the CT findings of four cases of squamous cell carcinoma, paying special attention to the epicenter of the lesion and the pattern of bony destruction. All four patients had a past history of chronic otitis media. Squamous cell carcinoma affected mainly the hypotympanum and inferior wall of the external auditory canal. and in all cases revealed an irregular pattern of bony destruction. Irregular destruction of the tegmen tympani occurred in two cases. In cases of squamous cell carcinoma, CT findings suggesting involvement of the promontory are usually noted. (author)

    The coexistence of two malignancies is rarely seen. A little association between hematologic malignancies especially multiple myeloma and renal cell carcinoma has been reported in the recent past. Several case series revealed a bidirectional association between these two malignancies which may be due to the common risk factors, similar cytokine growth requirements and clinical presentation. Here, we aim to describe a patient who had multiple myeloma and in his work up renal cell carcinoma was found out incidentally. We would like to create awareness among clinicians for the coincidence of Renal cell carcinoma and Multiple myeloma.

    Full Text Available Primary squamous cell carcinoma of renal pelvis is rare clinical entity with only few cases have been reported in the literature. It is usually associated with long standing renal calculi. Insidious onset of symptom and inconclusive clinical and radiological features leads to locally advanced or metastatic disease at presentation; resulting in poor prognosis. Here we are reporting two cases of squamous cell carcinoma of kidney having renal calculi to highlight its clinical presentation and to document the association of squamous cell carcinoma in longstanding nephrolithiasis due to its rarity.

    Invasion of bacteria into nonphagocytic host cells is an important pathogenicity factor for escaping the host defence system. Gram-positive organisms, for example Staphylococcus aureus and Listeria monocytogenes, are invasive in nonphagocytic cells, and this mechanism is discussed as an important part of the infection process. Uropathogenic Escherichia coli and Staphylococcus saprophyticus can cause acute and recurrent urinary tract infections as well as bloodstream infections. Staphylococcus saprophyticus shows strong adhesion to human urinary bladder carcinoma and Hep2 cells and expresses the 'Microbial Surface Components Recognizing Adhesive Matrix molecule' (MSCRAMM)-protein SdrI with collagen-binding activity. MSCRAMMs are responsible for adhesion and collagen binding in S. aureus and are discussed as an important pathogenicity factor for invasion. To investigate internalization in S. aureus, several fluorescence activated cell sorting (FACS) assays have been described recently. We used a previously described FACS assay, with slight modifications, in addition to an antibiotic protection assay and transmission electron microscopy to show that S. saprophyticus ATCC 15305 and the wild-type strain 7108 were internalized into the human urinary bladder carcinoma cell line 5637. The discovery of the internalization of S. saprophyticus may be an important step for understanding the pathogenicity of recurrent infections caused by this organism.

    The predictive value of the Ki-67 labelling index and its relationship with radiosensitivity in oral squamous cell carcinoma (SCC) remains controversial. We sought to evaluate whether the expression of Ki-67 antigen found in SCC of the tongue and the floor of the mouth is an indication for postoperative radiotherapy (PORT). The first study group included 34 patients who were treated only with primary surgery, while the second group included 26 patients who underwent primary surgery combined with PORT. The correlation between Ki-67 expression and loco-regional recurrence, as well as the 5-year disease-specific survival, was assessed in the two groups. Cases of high-proliferative tumours showed a significantly higher risk of loco-regional recurrence (P=0.018) and a poorer prognosis (P=0.001) only in the 34 patients treated with surgery alone. In multivariate Cox regression analysis, high Ki-67 expression was an independent predictor of loco-regional recurrence (HR 5.42, P=0.029) and disease-specific survival (HR 9.02, P=0.004). The correlation between Ki-67 expression and the risk of loco-regional recurrence in SCC of the tongue and the floor of the mouth may be useful in the selection of patients at a higher risk of recurrence who would benefit from PORT, despite adequate margins of resection and early stage of the disease.

    Full Text Available Renal cell carcinomas arise from the nephron but are heterogeneous in disease biology, clinical behavior, prognosis, and response to systemic therapy. Development of patient-specific in vitro models that efficiently and faithfully reproduce the in vivo phenotype may provide a means to develop personalized therapies for this diverse carcinoma. Studies to maintain and model tumor phenotypes in vitro were conducted with emerging three-dimensional culture techniques and natural scaffolding materials. Human renal cell carcinomas were individually characterized by histology, immunohistochemistry, and quantitative PCR to establish the characteristics of each tumor. Isolated cells were cultured on renal extracellular matrix and compared to a novel polysaccharide scaffold to assess cell-scaffold interactions, development of organoids, and maintenance of gene expression signatures over time in culture. Renal cell carcinomas cultured on renal extracellular matrix repopulated tubules or vessel lumens in renal pyramids and medullary rays, but cells were not observed in glomeruli or outer cortical regions of the scaffold. In the polysaccharide scaffold, renal cell carcinomas formed aggregates that were loosely attached to the scaffold or free-floating within the matrix. Molecular analysis of cell-scaffold constructs including immunohistochemistry and quantitative PCR demonstrated that individual tumor phenotypes could be sustained for up to 21 days in culture on both scaffolds, and in comparison to outcomes in two-dimensional monolayer cultures. The use of three-dimensional scaffolds to engineer a personalized in vitro renal cell carcinoma model provides opportunities to advance understanding of this disease.

    2015-03-01

    The goal of this study is to use gold nanoparticle as a diagnostic agent to detect human squamous carcinoma cells. Gold nanoparticles were synthesized and the gold nanoparticle size was 34.3 ± 6.2 nm. Based on the over-expression of epidermal growth factor receptor (EGFR) biomarkers in squamous carcinoma cells, we hypothesized that EGFR could be a feasible biomarker with a target moiety for detection. We further modified polyclonal antibodies of EGFR on the surface of gold nanoparticles. We found selected squamous carcinoma cells can be selectively detected using EGFR antibody-modified gold nanoparticles via receptor-mediated endocytosis. Cell death was also examined to determine the survival status of squamous carcinoma cells with respect to gold nanoparticle treatment and EGFR polyclonal antibody modification.

    AIM: To investigate the correlation between gammaglutamyl transpeptidase (γ-GTP) expression in the primary HCC and post-resection recurrence and its biological behaviors.METHODS: Forty consecutive patients having curative resection for HCC were included in this study. The primers for reverse-transcription polymerase chain reaction (RTPCR) were corresponding to the 5'-noncoding human γ-GTP mRNA of fetal liver (type A), HepG2 cells (type B),and placenta (type C). Both the cancer and non-cancerous tissues of the resected liver were analyzed. The correlations between the expression of γ-GTP and the clinicopathological variables and outcomes (recurrence and survival) were studied.RESULTS: Those with type B γ-GTP mRNA in cancer had significant higher recurrence rate than those without it (63.6 % vs 14.3 %). Both those with type B in cancer and in non-cancer died significantly more than those without it (45.5 % vs 0 % and 53.6 % vs 0 %, respectively). By multivariate analysis, the significant predictors of recurrence included high serum AFP (P=0.0108), vascular permeation (P=0.0084), and type B γ-GTP mRNA in non-cancerous liver (P=0.0107). The significant predictors of postrecurrence death included high serum AFP (P=0.0141),vascular permeation (P=0.0130), and daughter nodules (P=0.0053). As to the manifestations (recurrent number ≥2, recurrent extent≥2 segments, extra-hepatic metastasis, and death) in recurrent patients, there were no statistical significant differences between those with type B in the primary tumor and those without it. The difference between those with type B in non-cancerous liver and those without it also was not significant.CONCLUSION: Patients of HCC with type B γ-GTP mRNA both in cancer and in non-cancerous tissue had a worse outcome, earlier recurrence, and more post-recurrence death.

    Background The aim of this study was to investigate DNA content and expression of c-erbB-2, PS2, and prostate-specific antigen (PSA) proteins in breast carcinomas with neuroendocrine (NE) cell differentiation.Methods Chromogranin, c-erbB-2, PS2, and PSA in 131 samples of breast cancer were detected immunohistochemically. Classic Feulgen staining image analysis techniques were used to quantify DNA content in 81 of the breast cancer samples.Results The c-erbB-2 positive rate in breast carcinoma samples containing neuroendocrine cells was 37.5% and the rate of high expression of c-erbB-2 (++ or +++) was 33.3%, both significantly lower than that in breast carcinomas without neuroendocrine cells (62.6% and 68.7%, respectively, P 5c aneuploidy cells, and rate of aneuploidy among cells were all lower than that in NE (-) breast carcinomas (P<0.01). In NE (+) grade I or II breast carcinomas, these indices were also all lower than that in the NE (-) breast carcinoma samples (P<0.01).Conclusion Breast carcinomas with neuroendocrine differentiation have a lower rate of malignancy. Neuroendocrine differentiation could serve as a prognostic marker in clinical practice.

    Full Text Available Many investigations have revealed that a low recurrence rate of hepatocellular carcinoma (HCC is associated with high serum albumin levels in patients; therefore, high levels of serum albumin are a major indicator of a favorable prognosis. However, the mechanism inhibiting the proliferation of HCC has not yet been elucidated, so we investigated the effect of serum albumin on HCC cell proliferation. Hep3B was cultured in MEM with no serum or containing 5 g/dL human albumin. As control samples, Prionex was added to generate the same osmotic pressure as albumin. After 24-h incubation, the expressions of α-fetoprotein (AFP, p53, p21, and p57 were evaluated with real-time PCR using total RNA extracted from the liver. Protein expressions and the phosphorylation of Rb (retinoblastoma were determined by Western blot analysis using total protein extracted from the liver. For flow cytometric analysis of the cell cycle, FACS analysis was performed. The percentages of cell cycle distribution were evaluated by PI staining, and all samples were analyzed employing FACScalibur (BD with appropriate software (ModFit LT; BD. The cell proliferation assay was performed by counting cells with using a Scepter handy automated cell counter (Millipore. The mRNA levels of AFP relative to Alb(−: Alb(−, Alb(+, and Prionex, were 1, 0.7 ± 0.2 (p < 0.001 for Alb(−, and 1 ± 0.3, respectively. The mRNA levels of p21 were 1, 1.58 ± 0.4 (p = 0.007 for Alb(− and p = 0.004 for Prionex, and 0.8 ± 0.2, respectively. The mRNA levels of p57 were 1, 4.4 ± 1.4 (p = 0.002 for Alb(− and Prionex, and 1.0 ± 0.1, respectively. The protein expression levels of Rb were similar in all culture media. The phosphorylation of P807/811 and P780 of Rb protein was reduced in Alb(+. More cells in the G0/G1 phase and fewer cells in S and G2/M phases were obtained in Alb(+ than in Alb(− (G0/G1: 60.9%, 67.7%, 61.5%; G2/M: 16.5%, 13.1%, 15.6%; S: 22.6%, 19.2%, 23.0%, Alb(−, Alb

  2. Secondary prevention of recurrence by interferon therapy after ablation therapy for hepatocellular carcinoma in chronic hepatitis C patients

    Chronic hepatitis C is a leading cause of hepatocellular carcinoma (HCC) worldwide. Interferon (IFN) ther-apy decreases the incidence of HCC in patients with chronic hepatitis C. Prevention of chronic-hepatitis-C-related HCC is one of the most important issues in current hepatology. We have previously reported that male gender and high titer of hepatitis C virus (HCV) RNA are predictive factors for the development of HCC in HCV-related cirrhosis. Clinical efforts at eradicat-ing or reducing the viral load may reduce the risk for HCC. Furthermore, because HCC often recurs after ablation therapy, we performed a trial of IFN in pa-tients with chronic liver disease caused by HCV to see whether IFN therapy decreases recurrence after abla-tion therapy of HCV-related HCC. By using IFN therapy as a secondary prevention, patients with HCC who had received complete tumor ablation showed better sur-vival, primarily as a result of the preservation of liver function and also probably prevention of recurrence. Postoperative IFN therapy appears to decrease recur-fence after ablation therapy such as radiofrequency ablation (RFA) therapy of HCV-related HCC. We believe that there is a survival benefit in secondary prevention using IFN therapy. However, a controlled study is es-sential to obtain conclusive evidence of the efficacy of this strategy.

    Materials and Methods: Twenty two patients of post irradiated recurrent cervical carcinoma (PIRCC were enrolled in this prospective study. 18-fluorodeoxyglucose (FDG PET imaging was performed in each patient before the salvage therapy. The maximum standardized uptake value (SUVmax and metabolic tumor volume (MTV were measured and correlated with cumulative progression free survival (PFS. Results: Median age of patients was 42 years. Majority of patients had stage III disease at the initial presentation and all 22 patients had received prior definitive RT. The median recurrence free period was 11 months. Salvage therapy consisted of surgical resection or re-irradiation depending upon the various clinical and radiological factors. Median SUVmax was 5.8 (range 1.8-50.6 and median MTV was 43 cm 3 (range 5.8-243. The cumulative PFS for all patients was 20% at 30 months. The one-year PFS was 28% for patients with SUVmax value of >5.8 versus 42% for those with SUVmax value of 43 cm 3 versus 45% for those with MTV value of <43 cm 3 (P value 0.8. Conclusion: Our preliminary experience has suggested that FDG uptake on PET scan can predict the clinical outcome of PIRCC patients. Further randomized studies may be conducted with large sample size and longer follow up to establish its definite predictive value.

    2012-01-01

    Full Text Available Alpha-fetoprotein (AFP, des-γ-carboxy prothrombin (DCP, and lens culinaris agglutinin-reactive fraction of AFP (AFP-L3 have been developed with the intent to detect hepatocellular carcinoma (HCC and for the surveillance of at-risk patients. However, at present, none of these tests can be recommended to survey cirrhotic patients at risk for HCC development because of their suboptimal ability for routine clinical practice in HCC diagnosis. Starting from these considerations, these markers have been therefore routinely and successfully used as predictors of survival and HCC recurrence in patients treated with curative intent. All these markers have been largely used as predictors in patients treated with hepatic resection or locoregional therapies, mainly in Eastern countries. In recent studies, AFP has been proposed as predictor of recurrence after liver transplantation and as selector of patients in the waiting list. Use of AFP modification during the waiting list for LT is still under investigation, potentially representing a very interesting tool for patient selection. The development of a new predictive model combining radiological and biological features based on biological markers is strongly required. New genetic markers are continuously discovered, but they are not already fully available in the clinical practice.

    An adult, female Malayan sun bear (Helarctos malayanus) was diagnosed with squamous cell carcinoma of the rostral mandible. Initial treatment included bilateral mandibulectomy rostral to the lingual frenulum followed by intra- and perilesional cisplatin injections. Recovery after the procedure was uneventful and the Malayan sun bear adapted well to a shortened mandible. Histopathology indicated incomplete surgical excision of the tumor; therefore, radiation therapy was instituted weekly for four treatments at 2 Gy in parallel opposed fields (total 4 Gy each treatment) with one additional cisplatin treatment. Two years after initial presentation, the animal showed no recurrence of neoplasia.

    Clear cell papillary renal cell carcinoma (CCPRCC) is a low-grade renal neoplasm with morphological characteristics mimicking both clear cell renal cell carcinoma (CCRCC) and papillary renal cell carcinoma (PRCC). However, despite some overlapping features, their morphological, immunohistochemical, and molecular profiles are distinct. Micro-RNAs (miRNAs) are small noncoding RNAs that play a crucial role in regulating gene expression and are involved in various biological processes, including cancer development. To better understand the biology of this tumor, we aimed to analyze the miRNA expression profile of a set of CCPRCC using microarray and quantitative reverse transcription-polymerase chain reaction. A total of 15 cases diagnosed as CCPRCC were used in this study. Among the most differentially expressed miRNA in CCPRCC, we found miR-210, miR-122, miR-34a, miR-21, miR-34b*, and miR-489 to be up-regulated, whereas miR-4284, miR-1202, miR-135a, miR-1973, and miR-204 were down-regulated compared with normal renal parenchyma. To identify consensus of differentially regulated miRNA between CCPRCC, CCRCC, and PRCC, we additionally determined differential miRNA expression using 2 publically available microarray data sets from the NCBI Gene Expression Omnibus database (GSE41282 and GSE3798). This comparison revealed that the miRNA expression profile of CCPRCC shows some overlapping characteristics between CCRCC and PRCC. Moreover, CCPRCC lacks dysregulation of important miRNAs typically associated with aggressive behavior. In summary, we describe the miRNA expression profile of a relatively infrequent type of renal cancer. Our results may help in understanding the molecular underpinning of this newly recognized entity.

    2013-01-01

    Full Text Available Background: Papillary squamotransitional cell carcinoma (PSCC is a distinctive subcategory of squamous cell carcinoma of the uterine cervix. It has a propensity for local recurrence and late metastasis. Histologically, it can be misinterpreted as transitional cell carcinoma, or other papillary lesions of the cervix including squamous papilloma, verrucous carcinoma or cervical intraepithelial neoplasia grade 3 with papillary configuration. Materials and Methods: Nine cases of PSCC of the uterine cervix were diagnosed on a cervical biopsy specimen on routine hematoxylin and eosin (H and E stained sections. Their clinic-morphological features were analyzed. The cases were further evaluated immunohistochemically by cytokeratin 7 (CK7, cytokeratin 20 (CK20, p53 and Ki-67. Results: The patients ranged in age from 35 years to 75 years; with abnormal uterine bleeding being the most common clinical presentation. All the cases showed papillary architecture with fibrovascular cores lined by multilayered atypical epithelium. Three cell types were observed: Clear, intermediate and basaloid. Stromal invasion was seen in five cases, whereas in the remaining four cases, the biopsy specimen was too superficial to definitely assess invasion. Immunohistochemically, eight cases were CK7 + /CK20 - and one case was CK7 - /CK20 - . All nine cases showed nuclear accumulation of mutant p53. Moderate and high proliferative activity was observed in two and seven cases, respectively. Five of patients for whom follow-up information was available underwent radical hysterectomy and two of them were disease free 18 months following treatment. Conclusion: PSCC of the uterine cervix are a clinicomorphologically distinct group of cervical lesions that display a morphologic spectrum. They are potentially aggressive malignant tumors that should be distinguished from transitional cell carcinoma and other papillary lesions of the uterine cervix.

    2011-12-01

    Full Text Available The treatment of metastatic renal cell carcinoma (RCC has changed dramatically with the introduction of targeted therapies including sunitinib, sorafenib, and temsirolimus. Because patients with conventional clear cell histology account for 75- 80% of all patients with RCC, there has been little accumulated evidence on the treatment of patients with non-clear cell histologies. Most clinical trials have excluded them from enrolment, except for randomized studies investigating temsirolimus. Many retrospective studies on the use of all three of these targeted therapies in patients with non-clear cell histology have demonstrated response rates ranging from 3.7%–16%. Although response rates may not be as high compared to patients with clear cell histologies, targeted therapy does provide a clinically meaningful response.

  14. Radiation sensitivity of Merkel cell carcinoma cell lines

    Merkel cell carcinoma (MCC), being a small cell carcinoma, would be expected to be sensitive to radiation. Clinical analysis of patients at our center, especially those with macroscopic disease, would suggest the response is quite variable. We have recently established a number of MCC cell lines from patients prior to radiotherapy, and for the first time are in a position to determine their sensitivity under controlled conditions. Some of the MCC lines grew as suspension cultures and could not be single cell cloned; therefore, it was not possible to use clonogenic survival for all cell lines. A tetrazolium based (MTT) assay was used for these lines, to estimate cell growth after {gamma} irradiation. Control experiments were conducted on lymphoblastoid cell lines (LCL) and the adherent MCC line, MCC13, to demonstrate that the two assays were comparable under the conditions used. We have examined cell lines from MCC, small cell lung cancer (SCLC), malignant melanomas, Epstein Barr virus (EBV) transformed lymphocytes (LCL), and skin fibroblasts for their sensitivity to {gamma} irradiation using both clonogenic cell survival and MTT assays. The results show that the tumor cell lines have a range of sensitivities, with melanoma being more resistant (surviving fraction at 2 Gy (SF2) 0.57 and 0.56) than the small cell carcinoma lines, MCC (SF2 range 0.21-0.45, mean SF2 0.30, n = 8) and SCLC (SF2 0.31). Fibroblasts were the most sensitive (SF2 0.13-0.20, mean 0.16, n = 5). The MTT assay, when compared to clonogenic assay for the MCC13 adherent line and the LCL, gave comparable results under the conditions used. Both assays gave a range of SF2 values for the MCC cell lines, suggesting that these cancers would give a heterogeneous response in vivo. The results with the two derivative clones of MCC14 (SF2 for MCC14/1 0.38, MCC14/2 0.45) would further suggest that some of them may develop resistance during clonogenic evolution. 25 refs., 3 figs., 1 tab.

    The expression of E74-like factor 5 (ELF5) in epithelial ovarian carcinoma tissues and its effects on biological behavior in ovarian carcinoma cells were assessed in search for a new approach for gene treatment of epithelial ovarian carcinoma. RT-PCR technology was applied to detect the expression of ELF5 mRNA in epithelial ovarian carcinoma (n=49), borderline ovarian epithelial tumor (n=19), benign ovarian epithelial tumor (n=31) and normal ovarian tissues (n=40). Then, we transfected recombinant plasmid pcDNA3.1‑ELF5+EGFP into human ovarian carcinoma SKOV3 cells (recombinant plasmid group) in vitro and screened out stably transfected cells to conduct multiplication culture. Western blot analysis was performed to detect the expression of ELF5 protein in the different groups. Flow cytometry was employed to detect cell apoptosis and cycles. ELF5 mRNA in epithelial ovarian carcinoma and borderline ovarian epithelial tumor tissues were significantly lower (Pepithelial tumor and normal ovarian tissues. ELF5 protein expression in the cells of recombinant plasmid group was significantly higher compared with empty plasmid and blank control groups. The capacity of cell reproductive recombinant plasmid group at each time point decreased (P<0.05). Flow cytometry detection showed that 67.03% of cells in recombinant plasmid group was blocked in G0/G1 phase (P<0.05), compared with empty plasmid group (37.17%) and blank control group (38.24%). Apoptotic rate of recombinant plasmid group was significantly lower (31.4±1.9%; P<0.05), compared with that of empty plasmid group (9.1±2.2%) and blank control group (8.7±1.5%), and the differences were statistically significant. In conclusion, ELF5 interfered with cell cycle of human ovarian carcinoma SKOV3 cells and promoted apoptosis of human ovarian carcinoma SKOV3 cells inhibiting their growth and invasive capacity; and thus providing a new approach to gene treatment of ovarian carcinoma.

    Background Papillary renal cell carcinoma, accounting for 15% of renal cell carcinoma, is a heterogeneous disease consisting of different types of renal cancer, including tumors with indolent, multifocal presentation and solitary tumors with an aggressive, highly lethal phenotype. Little is known about the genetic basis of sporadic papillary renal cell carcinoma; no effective forms of therapy for advanced disease exist. Methods We performed comprehensive molecular characterization utilizing whole-exome sequencing, copy number, mRNA, microRNA, methylation and proteomic analyses of 161 primary papillary renal cell carcinomas. Results Type 1 and Type 2 papillary renal cell carcinomas were found to be different types of renal cancer characterized by specific genetic alterations, with Type 2 further classified into three individual subgroups based on molecular differences that influenced patient survival. MET alterations were associated with Type 1 tumors, whereas Type 2 tumors were characterized by CDKN2A silencing, SETD2 mutations, TFE3 fusions, and increased expression of the NRF2-ARE pathway. A CpG island methylator phenotype (CIMP) was found in a distinct subset of Type 2 papillary renal cell carcinoma characterized by poor survival and mutation of the fumarate hydratase (FH) gene. Conclusions Type 1 and Type 2 papillary renal cell carcinomas are clinically and biologically distinct. Alterations in the MET pathway are associated with Type 1 and activation of the NRF2-ARE pathway with Type 2; CDKN2A loss and CIMP in Type 2 convey a poor prognosis. Furthermore, Type 2 papillary renal cell carcinoma consists of at least 3 subtypes based upon molecular and phenotypic features. PMID:26536169

    Merkel cell carcinoma (MCC) is an aggressive cutaneous neuroendocrine malignancy that is associated with a poor prognosis. The pathogenesis of MCC is not well understood, and despite a recent plethora of mutational analyses, we have yet to find a set of signature mutations implicated in the majority of cases. Mutations, including TP53, Retinoblastoma and PIK3CA, have been documented in subsets of patients. Other mechanisms are also likely at play, including infection with the Merkel cell polyomavirus in a subset of patients, dysregulated immune surveillance, epigenetic alterations, aberrant protein expression, posttranslational modifications and microRNAs. In this review, we summarize what is known about MCC genetic mutations and chromosomal abnormalities, and their clinical significance. We also examine aberrant protein function and microRNA expression, and discuss the therapeutic and prognostic implications of these findings. Multiple clinical trials designed to selectively target overexpressed oncogenes in MCC are currently underway, though most are still in early phases. As we accumulate more molecular data on MCC, we will be better able to understand its pathogenic mechanisms, develop libraries of targeted therapies, and define molecular prognostic signatures to enhance our clinicopathologic knowledge.

    Full Text Available Renal cell carcinoma (RCC accounts for 90% of all kidney cancers. Due to poor diagnosis, high resistance to the systemic therapies and the fact that most RCC cases occur sporadically, current research switched its focus on studying the molecular mechanisms underlying RCC. The aim is the discovery of new effective and less toxic anti-cancer drugs and novel diagnostic markers. Besides the PI3K/Akt/mTOR, HGF/Met and VHL/hypoxia cellular signaling pathways, the involvement of the Wnt/β-catenin pathway in RCC is commonly studied. Wnt signaling and its targeted genes are known to actively participate in different biological processes during embryonic development and renal cancer. Recently, studies have shown that targeting this pathway by alternating/inhibiting its intracellular signal transduction can reduce cancer cells viability and inhibit their growth. The targets and drugs identified show promising potential to serve as novel RCC therapeutics and prognostic markers. This review aims to summarize the current status quo regarding recent research on RCC focusing on the involvement of the Wnt/β-catenin pathway and how its understanding could facilitate the identification of potential therapeutic targets, new drugs and diagnostic biomarkers.

    Merkel cell carcinoma (MCC) is a rare and aggressive cutaneous malignancy. The infectivity of Merkel cell polyomavirus (MCPyV), an apparent agent in MCC development, may be exacerbated with impaired immune responses. This paper reviews relevant data regarding the role of immunosuppression in the development of MCC and describes modes of immunodeficient states. Because of the inherently low incidence rate of MCC, several case studies and series are also briefly mentioned to provide a more comprehensive summary of MCC in the setting of immunosuppression. We describe immunosuppressed patients who have experienced excessive UV radiation, organ transplantation, human immunodeficiency virus infection/AIDS, autoimmune diseases, and lymphoproliferative disorders. Iatrogenic forms of immunosuppression are also highlighted. Studies that quantify risks consistently report that individuals with a history of solid organ transplantation, autoimmune diseases, AIDS, and/or lymphoproliferative diseases have a significantly elevated risk of developing MCC. Overall, immunocompromised patients also appear to have an early onset and more aggressive course of MCC, with poorer outcomes. Recommendations for multidisciplinary approaches are proposed to effectively prevent and manage MCC in these patients.

    AIM: To investigate the density of mast cells (MCs) in human hepatocellular carcinoma (HCC), and to determine whether the MCs density has any correlations with histopathological grading, staging or some baseline patient characteristics.METHODS: Tissue sections of 22 primary HCCs were histochemically stained with toluidine blue, in order to be able to quantify the MCs in and around the neoplasm using a computer-assisted image analysis system. HCC was staged and graded by two independent pathologists. To identify the sinusoidal capillarisation of each specimen 3μm thick sections were histochemically stained with sirius red, and semi-quantitatively evaluated by two independent observers. The data were statistically analysed using Spearman′s correlation and Student′s t-test when appropriate.RESULTS: MCs density did not correlate with the age or sex of the patients, the serum alanine aminotransferase (ALT) or aspartate aminotransferase (AST) levels, or the stage or grade of the HCC. No significant differences were found between the MCs density of the patients with and without hepatitis C virus infection, but they were significantly higher in the specimens showing marked sinusoidal capillarisation.CONCLUSION: The lack of any significant correlation between MCs density and the stage or grade of the neoplastic lesions suggests that there is no causal relationship between MCs recruitment and HCC. However, as capillarisation proceeds concurrently with arterial blood supply during hepatocarcinogenesis, MCs may be considered of primary importance in the transition from sinusoidal to capillary-type endothelial cells and the HCC growth.

    Full Text Available Abstract Background Correct detection of bone metastases in patients with esophageal squamous cell carcinoma is pivotal for prognosis and selection of an appropriate treatment regimen. Whole-body bone scan for staging is not routinely recommended in patients with esophageal squamous cell carcinoma. The aim of this study was to investigate the role of bone scan in detecting bone metastases in patients with esophageal squamous cell carcinoma. Methods We retrospectively evaluated the radiographic and scintigraphic images of 360 esophageal squamous cell carcinoma patients between 1999 and 2008. Of these 360 patients, 288 patients received bone scan during pretreatment staging, and sensitivity, specificity, positive predictive value, and negative predictive value of bone scan were determined. Of these 360 patients, surgery was performed in 161 patients including 119 patients with preoperative bone scan and 42 patients without preoperative bone scan. Among these 161 patients receiving surgery, 133 patients had stages II + III disease, including 99 patients with preoperative bone scan and 34 patients without preoperative bone scan. Bone recurrence-free survival and overall survival were compared in all 161 patients and 133 stages II + III patients, respectively. Results The diagnostic performance for bone metastasis was as follows: sensitivity, 80%; specificity, 90.1%; positive predictive value, 43.5%; and negative predictive value, 97.9%. In all 161 patients receiving surgery, absence of preoperative bone scan was significantly associated with inferior bone recurrence-free survival (P = 0.009, univariately. In multivariate comparison, absence of preoperative bone scan (P = 0.012, odds ratio: 5.053 represented the independent adverse prognosticator for bone recurrence-free survival. In 133 stages II + III patients receiving surgery, absence of preoperative bone scan was significantly associated with inferior bone recurrence

    Full Text Available Hyalinizing clear cell carcinoma (HCCC, so-called clear cell carcinoma, not otherwise specified (CCC (NOS, of the salivary glands is a rare and low-grade malignant tumor. We report a case of HCCC so-called CCC (NOS (referred to as HCCC of the minor salivary gland of the buccal mucosa. A 52-year-old woman had presented with a gradually growing and indolent mass in the right buccal mucosa for about two years. The first biopsy histopathologically suggested the possibility of malignancy derived from the minor salivary glands. A month later, she visited our hospital. The tumor measured approximately 1.5 cm in diameter and was elastic hard, smooth, and well movable. Image examinations demonstrated internal homogeneity of the lesion, which had a smooth margin, in the right buccal mucosa. Complete tumor resection followed by covering with a polyglycolic acid sheet and fibrin glue spray was performed without surgical flap reconstruction. Histopathological findings revealed proliferating tumor cells with clear cytoplasm surrounded by hyalinizing stroma in the submucosal minor salivary glands. Immunohistochemical stains revealed these tumor cells to be positive for epithelial cell markers but negative for myoepithelial ones. These findings confirmed the diagnosis of HCCC. Good wound healing and no evidence of local recurrence and metastasis have been shown since surgery.

    Three hundred and four patients with squamous cell carcinomas of the oral cavity were treated at the Finsen Institute in cooperation with the ENT-surgical departments between 1978 and 1982. The primary treatment consisted of radiotherapy alone in 74%, surgery alone in 4%, and a combination of radiotherapy and surgery in 15% of the patients. 2% received other treatment (cryotherapy), 5% did not complete the planned radiotherapy, and 1% were not treated at all. Of 203 patients with tumour remnant or first recurrence, 45% were operated, 2% received radiotherapy, and 2% combined treatment. This treatment strategy made 38% of the patients free of disease in the follow-up period (3 1/2 to 8 years) or until the patients died from other causes. Fifty-nine percent of the patients died from their oral carcinomas. Tumour size (T), lymph node status (N), and tumour stage were as expected important prognostic factors. (orig.).

    Hepatocellular carcinoma (HCC) is the sixth most common cancer and the third most frequent cause of cancer-related death worldwide. Despite advances in its diagnosis and treatment, the prognosis of patients with advanced HCC remains unfavorable. Recent advances in stem cell biology and associated technologies have enabled the identification of minor components of tumorigenic cells, termed cancer stem cells (CSC) or tumor-initiating cells, in cancers such as HCC. Furthermore, because CSC play a central role in tumor development, metastasis and recurrence, they are considered to be a therapeutic target in cancer treatment. Hepatic CSC have been successfully identified using functional and cell surface markers. The analysis of purified hepatic CSC has revealed the molecular machinery and signaling pathways involved in their maintenance. In addition, epigenetic transcriptional regulation has been shown to be important in the development and maintenance of CSC. Although inhibitors of CSC show promise as CSC-targeting drugs, novel therapeutic approaches for the eradication of CSC are yet to be established. In this review, we describe recent progress in hepatic CSC research and provide a perspective on the available therapeutic approaches based on stem cell biology.

    The number of new cases of thyroid cancer are dramatically increasing as incidences of this cancer have more than doubled since the early 1970s. Tall cell variant (TCV-PTC) papillary thyroid carcinoma is one type of thyroid cancer that is more aggressive and usually associated with higher local recurrence and distant metastasis. This variant can be identified through visual characteristics of cells in histological images. Thus, we created a fully automatic algorithm that is able to segment cells using a multi-stage approach. Our method learns the statistical characteristics of nuclei and cells during the segmentation process and utilizes this information for a more accurate result. Furthermore, we are able to analyze the detected regions and extract characteristic cell data that can be used to assist in clinical diagnosis.

    Background Sunitinib, a vascular endothelial growth factor pathway inhibitor, is an effective treatment for metastatic renal-cell carcinoma. We sought to determine the efficacy and safety of sunitinib in patients with locoregional renal-cell carcinoma at high risk for tumor recurrence after nephrectomy. Methods In this randomized, double-blind, phase 3 trial, we assigned 615 patients with locoregional, high-risk clear-cell renal-cell carcinoma to receive either sunitinib (50 mg per day) or placebo on a 4-weeks-on, 2-weeks-off schedule for 1 year or until disease recurrence, unacceptable toxicity, or consent withdrawal. The primary end point was disease-free survival, according to blinded independent central review. Secondary end points included investigator-assessed disease-free survival, overall survival, and safety. Results The median duration of disease-free survival was 6.8 years (95% confidence interval [CI], 5.8 to not reached) in the sunitinib group and 5.6 years (95% CI, 3.8 to 6.6) in the placebo group (hazard ratio, 0.76; 95% CI, 0.59 to 0.98; P=0.03). Overall survival data were not mature at the time of data cutoff. Dose reductions because of adverse events were more frequent in the sunitinib group than in the placebo group (34.3% vs. 2%), as were dose interruptions (46.4% vs. 13.2%) and discontinuations (28.1% vs. 5.6%). Grade 3 or 4 adverse events were more frequent in the sunitinib group (48.4% for grade 3 events and 12.1% for grade 4 events) than in the placebo group (15.8% and 3.6%, respectively). There was a similar incidence of serious adverse events in the two groups (21.9% for sunitinib vs. 17.1% for placebo); no deaths were attributed to toxic effects. Conclusions Among patients with locoregional clear-cell renal-cell carcinoma at high risk for tumor recurrence after nephrectomy, the median duration of disease-free survival was significantly longer in the sunitinib group than in the placebo group, at a cost of a higher rate of toxic events
