  1. Laryngeal adenocystic carcinoma treated by proton therapy

    International Nuclear Information System (INIS)

    Adenocystic carcinoma most commonly develops in the major salivary glands, on the other hand it is rare for adenocystic carcinoma to develop in the larynx. We report a case of adenocystic carcinoma in the larynx. A 54-year-old male was hospitalized with symptoms of hoarseness and dyspnea on exertion. He presented a tumor that developed at the base of the right arytenoid, and covered over the glottis. It was confirmed to be adenocystic carcinoma (solid type) by biopsy. Positron emission tomography (PET)-CT also revealed a left cervical lymph node metastasis and multiple pulmonary metastases (T1N2cM1). He was treated with proton therapy to the larynx to prevent airway obstruction by growth of the tumor and to preserve the larynx because he had uncontrollable pulmonary metastasis. Although the tumor vanished after the treatment, one month later he had halitosis, dyspnea and bilateral vocal cord palsy. Despite administration of an antibacterial drug and steroid, there was no improvement to the narrowness of the glottis. A tracheotomy was therefore performed three months after the proton therapy. PET-CT, which was performed after the tracheotomy, suggested growth of the residual tumor or laryngeal radionecrosis. This study confirmed that proton therapy is effective for adenocystic carcinoma in the larynx. However, proton therapy also was found to cause laryngeal radionecrosis. These results indicate the importance of evaluating the side effects of radiation therapy and providing that information to the patient. (author)

    Surgical resection and imaging guided treatments play a crucial role in the management of hepatocellular carcinoma (HCC). Although the primary end point of treatment of HCC is survival, radiological response could be a surrogate end point of survival, and has a key role in HCC decision-making process. However, radiological assessment of HCC treatment efficacy is often controversial. There are few doubts on the evaluation of surgical resection; in fact, all known tumor sites should be removed....

    Increasing exposure to UV radiation is considered the most important etiologic factor of nonmelanoma skin cancers. Consequently, exposed areas such as the scalp and face, are the primary areas for developing non-melanoma skin cancers. Once a patient has presented with one tumor, additional lesions are common. The diagnosis is based on typical clinical picture and biopsy or excision for histopathological analysis. Various non-surgical treatment options have been established. Superficial basal cell carcinoma, superficial carcinoma in situ and all actinic keratoses are preferentially treated non-surgically. Most other basal cell and squamous cell carcinomas should be surgically removed. PMID:24724463

    Objective To discuss the prognosis of primary liver carcinoma treated with local resection and factors affecting prognosis.Methods The data of 130 patients who had been treated from October 1989 to October 1995 were analyzed retrospectively. We analyzed the concrete operating methods, the cause of postoperative complications and factors affecting prognosis.Results Curative local resection was performed in 130 patients. Operation-related mort ality was 0.8% and the incidence of complication was 16.1% (n=18). The overal l 1-, 3- and 5-year survival rates were 82.1%, 60.6% and 48.2%, respective ly. Involvement of blood vessels or liver capsules and the elevation of AST bef ore operation were the significant factors affecting prognosis (P<0.05).Conclusion Local resection is a safe method characterized by little damage, rapid, less blo od loss, low complication rate and good prognosis.

    Full Text Available Radiofrequency ablation (RFA recently has been applied to benign thyroid nodules, mainly for the cosmetic reasons, and limited cases of local recurrences or focal distant metastases of well-differentiated thyroid cancer, in the high-risk reoperative condition or for the palliative purpose. But no report has been made on the RFA for primary thyroid cancer to date. We report on a patient with primary papillary carcinoma of thyroid gland who had undergone RFA before the cytological diagnosis of malignancy, later referred and treated with robotic surgery successfully. We can learn the following lessons from our case; (1 the RFA for operable primary thyroid malignancy should be avoided, because of the possibility of remnant viable cancer and undetectable nodal metastasis, and (2 robotic or endoscopic thyroid surgery may be a feasible operative method for benign or malignant thyroid nodules previously treated with RFA.

    Twenty-two patients with squamous carcinoma of the nasal vestibule were treated at the University of Florida Division of Radiation Therapy with curative intent. Fifteen lesions were de novo and seven recurrent after surgery. By AJCC classification, 7 lesions were Tx or T1, 2 were T2, 2 were T3, and 11 were T4. Management of the primary tumor and regional lymphatic drainage was highly individualized. Local control was achieved in 19 out of 22 lesions. The ultimate regional lymph node control rate was 22 out of 22, although two patients required radical neck dissection after development of lymph node disease in untreated regional lymphatics. Two patients have died of cancer and three of intercurrent disease. Cosmetic results are generally excellent but may be compromised by previous surgery in recurrent lesions or tumor destruction of normal tissues in advanced lesions. Complications of treatment are minimal.

  8. Effectiveness of brachytherapy in treating carcinoma of the vulva

    International Nuclear Information System (INIS)

    Purpose: Radical radiotherapeutic management of vulvar cancer often incorporates brachytherapy as a portion of the treatment regimen. However, few studies using this modality alone to manage vulvar cancer have been published. Methods and Materials: Thirty four patients were treated with iridium-192 (192Ir) brachytherapy for vulvar cancer between 1975 and 1993 at Centre Alexis Vautrin. Twenty-one patients were treated at first presentation when surgery was contraindicated or declined. Of these patients, 12 had International Federation of Gynecology and Obstetrics Classification Stage III or IV disease, 8 were Stage II, 1 was Stage I, and 1 was Stage 0. Thirteen patients were treated for recurrent disease. Paris system rules for implantation and dose prescription were followed. The median reference dose was 60 Gy (range 53 to 88 Gy). At the time of analysis, 10 of 34 patients were alive. Median follow-up in these 10 patients was 31 months (range: 21 months to 107 months). Fourteen of the 24 deaths were from causes other than vulvar cancer. Results: Kaplan-Meier actuarial 5-year local control was 47% (95% confidence interval (CI) = 23 to 73%) and 5-year actuarial loco-regional control was 45% (95% CI = 21 to 70%). Kaplan-Meier actuarial 5-year disease-specific survival was 56% (95% CI = 33 to 76%) and actuarial 5-year survival was 29% (95% CI = 15 to 49%). Median time to death was 14 months. Subset analysis revealed a higher actuarial 5-year local control in patients treated at first presentation than those treated for recurrence (80 vs. 19%, log rank, p = 0.04). Similarly, actuarial 5-year loco-regional control was higher in patients treated at first presentation (80 vs. 16%, log rank, p 0.01). The two groups did not differ significantly in disease-specific or overall survival. The actuarial 5-year disease specific survival of 56% is somewhat less than the expected 5-year disease-specific survival after surgery in a group having a similar proportion of early stage

    1988-07-01

    This is an analysis of 34 patients with carcinoma of the cervical esophagus treated with radiation therapy with curative intent at the University of Florida between September 1966 and May 1985. All patients have a minimum 2-year follow-up and 28 (82%) have at least 5 years of follow-up. Patients were staged according to the recommendations of the AJCC. Patients who died within 2 years of treatment with the primary site continuously disease-free were excluded from the local control analysis; all patients were included in the analysis of complications and survival. Irradiation resulted in control of the primary lesion in 1 of 2 patients who presented with T1 lesions, in 4 of the 12 patients with T2 lesions, and 3 of 17 patients who presented with T3 lesions. One patient with a T3 lesion that recurred locally was successfully salvaged by an operation. The 5-year absolute survival rates by stage were as follows: no patients with stage I lesions survived; of 11 stage II patients, one survived; and of 16 stage III patients, three survived. Interestingly, all four of the 5-year survivors were women.

    The Oncology Grand Rounds series is designed to place original reports published in the Journal into clinical context. A case presentation is followed by a description of diagnostic and management challenges, a review of the relevant literature, and a summary of the authors' suggested management approaches. The goal of this series is to help readers better understand how to apply the results of key studies, including those published in Journal of Clinical Oncology, to patients seen in their own clinical practice.A 78-year-old woman with a past medical history of hepatitis C virus (HCV) presented on routine examination to her family doctor with abnormal liver function tests. She was referred for liver ultrasound, which detected a liver mass. Multiphasic magnetic resonance imaging (MRI) diagnosed liver cirrhosis and a segment 7/8 lesion measuring 4 cm, suspicious for a hepatocellular carcinoma (HCC), without evidence of portal hypertension. Child-Pugh (CP) score (ranging from 5 to 15) is a clinically relevant measure of synthetic liver function, based on international normalized ratio and albumin and bilirubin levels, as well as presence or absence of ascites and encephalopathy. A score of A5 or 6 is associated with better postoperative survival compared with CP B7 to 9 or CP C10 to 15, in which surgery is contraindicated. Her CP score was A6, based on a low albumin of 34 g/L. Platelets were slightly depressed at 121,000 μL, and alpha-fetoprotein level was 89 μg/L. She had not received treatment of her HCV because of her age and low viral load. She does not drink alcohol. Clinically the patient had an Eastern Cooperative Oncology Group performance status (PS) of 1, no stigmata of chronic liver disease, and no ascites or encephalopathy or other associated clinical symptoms. An HCC multidisciplinary cancer conference recommended surgical resection. The patient was taken to the operating room for a planned liver nonanatomic wedge resection. At the time of laparotomy

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

    Ninety-one patients with histologically proven anaplastic carcinoma of the thyroid were referred to the Beatson Oncology Centre between 1961 and 1986. The female:male ratio was 2.4:1 and the median age at presentation was 70 (range 38-92) years. All patients had a thyroid mass at presentation and the most common symptoms were dyspnoea, dyspnagia and dysphonia. Five patients had a total thyroidectomy and 28 partial thyroidectomy. Ninety five per cent of patients received external beam radiotherapy. Results show dyspnoea to be the only symptom strongly influencing survival. Total or partial thyroidectomy is associated with increased survival. This association is most marked for patients presenting without dyspnoea. Eighty per cent of patients responded to radiotherapy.

    Malignant melanoma can be successfully treated when it is identified in its early stages, but the disease is associated with a poor prognosis when it is detected in an advanced stage. Papillary thyroid carcinoma is a thyroid cancer that has a good prognosis. The present study reports a rare case of malignant melanoma and papillary thyroid carcinoma that were diagnosed concurrently and treated simultaneously. The present patient was a 37-year-old male, in whom examination of a skin biopsy that was obtained from a lesion in the right retroauricular region revealed the lesion to be consistent with malignant melanoma. The patient underwent radical neck dissection upon the detection of malignant melanoma metastasis to the sentinel lymph node. Metastases of papillary thyroid carcinoma were detected in four out of 38 lymph nodes. The patient was then diagnosed with papillary thyroid carcinoma and underwent total thyroidectomy. The patient was administered with high-dose followed by moderate-dose interferon-α therapy for the treatment of malignant melanoma. The patient also received concurrent radioactive iodine therapy for the treatment of papillary thyroid carcinoma, at the same time as the interferon therapy. The two primary tumors of the patient were treated successfully. During therapy, no serious side-effects were observed, with the exception of fever caused by high-dose interferon therapy. Malignant melanoma and papillary thyroid carcinoma may occur concurrently, although this is rarely observed. The present study reports a rare case that demonstrates that the two tumors can be successfully treated simultaneously. PMID:25436010

    International Nuclear Information System (INIS)

    Objective: To summarize the author's experience which was obtained in observing and nursing the adverse reactions of advanced hepatocellular carcinoma patients who were treated with Sorafenib. Methods: The adverse reactions and their severity observed in 34 patients with advanced hepatocellular carcinoma who were treated with Sorafenib were retrospectively analyzed. Results: Side effects or toxic reaction were observed in all the patients, which included neutropenia, foot-hand syndrome (FHS), fatigue, diarrhea, hypertention, rash, etc. Five patients had to cut down the dose of Sorafenib in order to relieve the symptom, among them one patient had grade 4 FHS, 3 patients had grade 3 FHS and one patient had grade 3 neutropenia. Conclusion: Being familiar with sorafenib's adverse reaction, closely observing the patients condition and affording appropriate nursing measures, all the above items can definitely improve the therapeutic results and patient's living quality.

  20. Elevated cyclooxygenase-2 expression correlates with diminished survival in carcinoma of the cervix treated with radiotherapy

    International Nuclear Information System (INIS)

    Purpose: The purpose of this study was to examine the relationship between overall survival and prognostic factors in carcinoma of the cervix treated with radiation therapy. A clinicopathologic study was performed on 24 patients. Methods and Materials: Formalin-fixed, paraffin-embedded tumor biopsies were stained for Cyclooxygenase-2 (COX-2), Topoisomerase I, Topoisomerase II, and p53. Clinical factors such as stage, grade, tumor size, pre- and post-treatment hemoglobin level, and radiotherapy dose were also evaluated. Results: Median follow-up was 75 months for living patients. The only immunohistochemical or clinical factor that was associated with improved survival was decreased COX-2 distribution staining. High COX-2 distribution staining was associated with decreased overall survival (p=0.021) and decreased disease-free survival (p=0.015) by log-rank comparison of Kaplan-Meier survival curves. The 5-year overall survival rates for tumors with low vs. high COX-2 distribution values were 75% and 35%, respectively. COX-2 staining intensity was found to correlate positively with tumor size (p=0.022). Conclusion: These findings indicate that increased expression of COX-2 portends a diminished survival in patients with invasive carcinoma of the cervix treated with radiotherapy. Because COX-2 is an early-response gene involved in angiogenesis and inducible by different stimuli, these data may indicate opportunity to intervene with specific inhibitors of COX-2 in carcinoma of the cervix

    Objective: To investigate the effect of cryotherapy of employing Argon/Helium assisted with TACE for the unresectable primary liver carcinoma. Methods: 124 cases with primary liver carcinoma were randomly divided into two groups: 60 cases were treated by TACE and cryotherapy; the other 64 cases were simply done by TACE as control. In general, TACE was undertaken once a month and altogether three times for a course. Cryotherapy was undergone 1-3 times for a course. Results: The total effective rates (CR + PR) were 45.3% for the control group and 68.3% for the combined therapy group, with an obvious difference between the two groups, 0.5, 1, 1.5 years survival rate were 81.3%, 62.5%, 43.8% respectively in the control group; 93.3%, 83.3%, 63.3% respectively for the combined group. There was an obvious difference between the two groups of 1, 1.5 years of survival rates. Conclusions: Cryotherapy of employing Argon/Helium assisted with TACE for the unresectable primary liver carcinoma is feasible with raising the effective rate and prolonging survival time. (authors)

    Maximum safe activity calculation, that has to be administered for treatment to patients having Differentiated Thyroid Cancer (CADT). No important side effects should be produced. Post treatment evolution was analysed. 23 Dosimetric studies were performed determining blood and whole body uptake curves (CE)during 5 days. Using the MIRDOSE software, the maximum safe activity in the whole body (CE)was calculated. The retained activity in the body (AR), 48 hs. post tracer dose. Should have been less than 2.96 GBq so as to avoid lung fibrosis. 17 patients that received activities<11.1 GBq, had no side effects. Three patients presents special situations: high AR, users in the mouth, and plaque to and leucopenia. This methodology has benefits because AT can be estimated. This was possible for 85% of the patients. When AR was high at 48 hr, AT was diminished to avoid pulmonary lesions. Tumor absorbed dose estimation, will allow the administration of AT>11.1 GBq in the future. (Author)

Malignant degeneration into squamous cell carcinoma is quite common, although curative approaches vary a lot in modern literature.Case report: We report a case of a 66-year-old male patient with the coexistence of multiple squamous cell papilloma and carcinoma in the upper trachea with severe airway obstruction that was diagnosed through bronchoscopy and treated by performing an urgent tracheostomy, followed by concurrent chemotherapy and radiotherapy. There was no evidence of recurrence after a 12-month follow-up period.Conclusion: This study underlines the diagnostic and therapeutic value of bronchoscopy as well as multimodality palliative treatment in such cases. To the best of our knowledge, this is the first study to describe an immediate treatment protocol with tracheostomy and concurrent chemotherapy/radiotherapy in a patient with squamous cell tracheal papilloma and carcinoma

    To investigate the therapeutic effect of dendritic cells pulsed with lysates of heat-treated CT26 colon carcinoma cells. Bone marrow-derived DCs were pulsed with lysates of heat-treated tumor cells and were used to immunize BALB/c mice with established colon carcinoma. Cytotoxic T lymphocyte (CTL) response was detected. The therapeutic effect induced by DCs was observed by tumor weight and survival time. DCs pulsed with lysates of heat-treated tumor cells markedly induced specific cytotoxic activity of CTLs. Tumor growth in the immunized BALB/c mice was significantly inhibited and the survival time of the tumor-bearing mice was prolonged. DCs pulsed with lysates of heat-treated tumor cells have an observable therapeutic effect on established colon carcinoma-bearing mice.

    Full Text Available Background toxicity of the respiratory system is quite common after radiotherapy of thoracic tumors. Breast and lung cancer patients represent one of the groups for whom there is a long expected survival. The quantification of lung tissue response to irradiation is important in designing treatments associated with a minimum of complication and maximum tumor control. OBJECTIVE :- To study the impact of lung volume irradiated on early pneumonitis in patients undergoing RT for cancer breast. METHOD :- The Study was conducted as per ICH GCP guidelines and Ethics Committee approval.This is a prospective study of cancer of breast and lung treated with radiotherapy from February 2004 to January 2005. Computerized tomography (CT simulation was part of treatment planning. The volume of lung irradiated was calculated by using both CLD method and summation of area technique. Chest x-ray and spirometric tests were done first as a baseline procedure and later at one month and at 3 months after completion of radiotherapy. Patients of either sex and Karnofsky performance status (KPS>70 and all cases of carcinoma breast and lung receiving radiotherapy were included.Patients who have received previous chemotherapy with drugs like bleomycin and mitomycin were excluded from the study. RESULTS. The incidence of RP in carcinoma breast is 3.9%. With conventional technique of treatment planning for carcinoma breast, percentage of lung volume irradiated in majority of cases (16/26 was within 11% and Central Lung Distance (CLD proved to be best predictor of it. The spirometry evaluation showed reduction in the percentage values in different compartments patients. Changes were maximum in patients treated with anthracyclin-based chemotherapy also. INTERPRETATION AND CONCLUSION The incidence of RP of carcinoma breast is 3.9% treated with locoregional radiotherapy, which is accepted globally. The CLD (Central Lung Distance method of calculation of PIV (Percentage of

    Xeroderma pigmentosum (XP) is an autosomal recessive disease characterized by solar sensitivity, photophobia, early onset of freckling, and solar-induced cutaneous neoplastic changes. Management of patients with XP is a therapeutic challenge as they usually develop multiple cutaneous malignancies, making surgical therapy difficult, and continue to form skin malignancies at a high rate. We describe a 30-year-old Chinese man with XP who had been previously treated with excision and dermatoplasty. Upon recurrence of multiple superficial, ulcerative, and pigmented lesions, imiquimod 5% cream was recommended for 4 months. His multiple facial lesions demonstrated an excellent response to topical imiquimod 5% cream with minor side effects. This favorable response indicates that topical application of imiquimod 5% cream is an effective means of treating multiple basal cell carcinomas in XP. PMID:25754701

    Previous studies have reported that telomere length in peripheral blood leukocytes can predict the clinical outcome of several cancers. However, whether leukocyte telomere length is associated with the prognosis of hepatocellular carcinoma (HCC) remains to be determined. In this study, relative telomere length (RTL) in peripheral blood leukocytes was measured using a real-time PCR-based method for 269 HCC patients treated with transarterial chemoembolization (TACE) from two independent hospitals. The association between RTL and the overall survival (OS) of HCC was analyzed. The immunological function of the HCC patients with different leukocyte RTLs was evaluated. Multivariate analyses indicated that long leukocyte RTL was significantly associated with poor OS of HCC patients, with a hazard ratio of 2.04 (95% confidence interval, 1.46-2.86; P HCC patients treated with TACE.

  12. Testicular function in patients with differentiated thyroid carcinoma treated with radioiodine

    International Nuclear Information System (INIS)

    The aim of the present study was to assess whether 131I therapy for differentiated thyroid carcinoma (DTC) can affect endocrine testicular function. Serum follicle-stimulating hormone (FSH) and testosterone (T) concentrations were measured in 103 patients periodically submitted for radioiodine therapy for residual or metastatic disease. Mean follow-up was 93.7±54 mo (range 10-243 mo). Mean FSH values in 131I-treated patients tested after their last treatment were 15.3±9.9 mU/ml, significantly higher than those of 19 untreated patients (6.5±3.1 mU/ml). Considering the mean +3 s.d. FSH of untreated subjects as the upper limit of normal range, 36.8% of the patients had an abnormal increase in serum FSH. Longitudinal analysis performed in 21 patients showed that the behavior of FSH in response to 131I therapy was not universal. Six patients had no change or a slight increase in serum FSH after 131I administration; eleven patients had a transient increase above normal values 6-12 mo after 131I treatment, with return to normal levels in subsequent months. The administration of a second dose was followed by a similar increase in FSH levels. Finally, four patients, followed for a long period of time and treated with several 131I doses, showed a progressive increase in serum FSH, which eventually became permanent. Semen analysis, performed in a small subgroup of patients, showed a consistent reduction in the number of normokinetic sperm. No change was found in serum T levels between treated and untreated patients. The results indicate that 131I therapy for thyroid carcinoma is associated with transient impairment of testicular germinal cell function. The damage may become permanent for high-radiation activities delivered year after year and might pose a significant risk of infertility. 14 refs., 8 figs., 1 tab

  13. External radiotherapy for carcinoma of the eyelid: report of 850 cases treated

    International Nuclear Information System (INIS)

    Purpose: We report a retrospective series of 850 patients treated by external irradiation for carcinoma of the eyelid at Institut Curie and we compare our results with other techniques: brachytherapy and surgery. Methods and Materials: Eight hundred fifty patients were treated by external radiotherapy for carcinoma of the eyelid. None of these patients have been previously treated. All the patients were classified according to the TNM classification of (UICC). We distinguished five histological types and five clinical groups according to the site of the skin tumor. Three modalities of external radiotherapy were used: contact therapy, conventional radiotherapy, and electrontherapy. We reviewed the clinical files of the 850 patients who went regularly at follow-up visits. Results: We report the 5-year survival results--alive with no evidence of disease: 72%; alive with progression: 2%; died from tumor progression: 0.5%; died from intercurrent disease: 19.5%; and lost to follow-up: 5%. The 5-year local control rate was 97.5%. We observed 45 failures--lymph node, metastatic, and local--and emphasize this last group by presenting the results of treatment of these local failures. We studied the complications of treatment: 2.3% of corneal complications, 2% of cataracts, and 1.4% of serious ocular complications. Conclusions: Our results concerning local failures and loss of the eye are comparable to those reported for other techniques involving brachytherapy or surgery. Overall, external radiotherapy is a safe and effective treatment, as it ensures a high local control rate and provides perfectly satisfactory functional and esthetic results. It seemed particularly useful to report this series in that few publications are available on this subject that, nevertheless, constitutes a topical issue

    Basaloid squamous cell carcinoma (BSC) of the esophagus is a rare malignant disease. We report here a patient with recurrent esophageal BSC, who was successfully treated by systemic chemotherapy containing 5-fluorouracil (5-FU) and cisplatin (CDDP). A 57-year-old woman was diagnosed as having squamous cell carcinoma of the esophagus upon endoscopic examination. Curative esophagectomy with lymph node dissection was performed under the thoracoscope. The pathological diagnosis of the surgical specimen was BSC.Five months after operation, the patient was diagnosed as having a recurrence of the BSC with metastases to the liver and spleen, and a right paraclavicular lymph node. She was given systemic chemotherapy consisting ofcontinuous infusion of 800 mg/d of 5-FU and 3 h infusion of 20 mg/d of CDDP for 5 consecutive days every 4 wk. The metastatic lesions in the spleen and right paraclavicular lymph node disappeared, and the liver metastasis was apparently reduced in size after 2 courses of chemotherapy. The tumor regression was seen over 6 courses, with progression afterwards.Although subsequent treatment with CPT-11 and CDDP was not effective, docetaxel and vinorelbine temporarily controlled the tumor growth for 2 mo. 5-FU and CDDP combination may be useful for the patients with advanced BSC.

  15. Effect of vitamin E on protein bound carbohydrate complexes in radiation treated oral squamous cell carcinoma patients

    International Nuclear Information System (INIS)

    Serum glycoproteins were evaluated in oral squamous cell carcinoma patients treated with radiotherapy and also the effect of vitamin E was studied. Cell surface glycoconjugates are important parameters in the detection of malignancy. Thus, the objective of the present study is to evaluate the efficacy of vitamin E on glycoproteins in oral cavity cancer patients treated with radiotherapy. The study includes 26 age and sex matched normal healthy individuals and 26 patients with squamous cell carcinoma of oral cavity. These patients were divided into two groups, one for radiotherapy alone (at a dosage of 6000 cGy in five fractions per week for a period of six weeks) and the other for radiotherapy plus vitamin E supplementation (at a dosage of 400 IU/day of vitamin E) for the entire period of radiotherapy. Levels of hexose, hexosamine, fucose and sialic acid were increased in oral squamous cell carcinoma patients and a significant decrease was observed in radiation treated patients when compared to control. The levels of glycoconjugates were significantly decreased in radiation treated patients supplemented with vitamin E. This measurement may be useful in assessing disease progression and identifying patients resistant to therapy and a possible role of vitamin E on reduction in glycoconjugate levels of radiation treated oral squamous cell carcinoma patients.

However, the recovery of the voice after SCL may result in different degrees of dysphonia. To improve the functional recovery and quality of the voice, we realized a modified supracricoid laryngectomy (MSCL using sternohyoid muscles for neoglottic reconstruction in selected patients affected by T1b–T2 laryngeal cancer. In this study, we evaluate the quality of life (QoL in patients treated by SCL and MSCL.Methods: The quality of life (QoL evaluation was undertaken using the Italian version of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire.Results: The overall QoL, assessed with European Organization for Research and Treatment of Cancer Quality of Life Questionnaire C30, was better in patients treated with MSCL than in those treated with SCL. The better QoL correlates with the highest response scores to the questions on the relative global functioning scales in patients treated with MSCL.Conclusion: The new surgical technique has improved the QoL of patients with early laryngeal cancer, with improved communication ability achieved. Reconstruction of neocords in MSCL improves speech function in comparison to SCL, and patients experience less discomfort and achieve an almost normal communication performance.Keywords: supracricoid laryngectomy, quality of life, laryngeal carcinoma, EORTC QLQ

    Background and purpose: imatinib (Gleevec {sup registered}, Glivec {sup registered}) is an inhibitor of {alpha}-and {beta}-platelet-derived growth factor receptors and other tyrosine kinases, that are also associated with the function of growth factors. Imatinib has been approved for the treatment of chronic myelogenous leukemia and gastrointestinal stromal tumors and is under investigation for the therapy of several other malignant tumors. Since radiotherapy is an important treatment option in many tumors, combined effects of imatinib and radiation were analyzed here. Material and methods: in vitro, U87 cells (human glioblastoma), A431 cells (human epidermoid carcinoma), and HUVECs (human umbilical, venous endothelial cells) were treated with imatinib alone and in combination with radiation. Clonogenic survival and cell proliferation were determined with and without additional radiation (0-10 Gy). In vivo, U87 and A431 cells (5 x 10{sup 6}) were subcutaneously injected into hind limbs of balb c nu/u mice. Drug and radiation treatments started on day 0 when tumor volumes were approximately 400-500 mm{sup 3}. Tumors were treated with 5 x 5 Gy (U87) or 6 x 5 Gy (A431) on consecutive days from day 0. Imatinib was administered orally via the mouse diet starting on day 0 until the end of observation. Tumor growth and microvessel density (CD31 IHC) were analyzed. Results: in vitro, imatinib increased radiosensitivity of U87 and A431 tumor cells as well as HUVECs in both clonogenic and cell number/proliferation assays. The enhancement of radiosensitivity in HUVECs was comparable to that observed in the tumor cells. In vivo, the concurrent and continuous administration of imatinib increased tumor growth delay of fractionated radiotherapy in the carcinoma and the glioblastoma models at reduced microvessel densities. No apparent additional toxicity by the combination of radiation and imatinib versus monotherapies was observed in terms of weight, skin, or general behavior

    Kindler syndrome1, 2 is a genetic disorder mainly characterized by increased skin fragility and photosensitivity,3, 4 making the use of treatments based on radiation difficult or even prohibited. Thus, cases reporting Kindler syndrome patients treated with radiotherapy are rare. In this study, we report clinical outcomes and care provided for a rare case of a Kindler syndrome patient submitted to radiotherapy. Diagnosed with squamous cell carcinoma involving the buccal mucosa, the patient was exclusively treated with radiotherapy, with 70 Gy delivered on the PTV with the Volumetric Modulated Arc technique. The patient's reaction regarding control of the lesion is relevant compared to patients not affected by the syndrome. We noticed acute reactions of the skin and buccal mucosa after few radiotherapy sessions, followed by a fast reduction in the tumor volume. The efficacy of radiotherapy along with multidisciplinary actions allowed treatment continuity, leading to a complete control of the lesion and life quality improvement and showed that the use of radiotherapy on Kindler syndrome patients is possible.

    In Denmark there is an increasing frequency of laryngeal carcinoma, in particular in women and among these especially in supraglottic tumours. The incidence during the past 20 years has risen from about 40 to 60 cases per million per year. A series of 335 consecutive patients treated with primary radiation is presented. In one-third of all patients the tumour was localized in the supraglottic area; in women in more than half and in men in about one-fourth of the cases. The frequency of primary lymph node metastases in the supraglottic and the glottic tumours was 24% and 2% respectively. A multivariate analysis identified sex and tumour size as independent prognostic parameters of local control. Five-year survival corrected for intercurrent deaths was obtained in 59% of all cases, in 56% of supraglottic and in 92% of glottic tumours. A multivariate analysis defined localization, tumour grade and stage as independent prognostic parameters of survival. Salvage surgery was performed in about 32% of the cases, total laryngectomy in 26%, and partial laryngectomy in 6%. The survival rate among all total laryngectomies was 55%. A tracheostomy during or before radiation treatment prior to total laryngectomy had no influence on complication rate, admission time or recurrence rate. The frequency of pharyngo-cutaneous fistulae in the entire series was 11.5%; after routine use of metronidazol, however, only 5.7%. Radical neck dissection was carried out in 7.8% of the cases, by far most in the supraglottic group, only a few in the glottic carcinomas, in three-fourth in connection with a laryngectomy and in one-fourth without local recurrence in the larynx.

  3. Association between genetic polymorphisms and carotid atherosclerosis in patients treated with radiotherapy for nasopharyngeal carcinoma

    International Nuclear Information System (INIS)

    Radiotherapy (RT) of the neck is commonly given to nasopharyngeal carcinoma (NPC) patients for preventing cervical lymph node metastasis. However, neck RT may induce the development of carotid atherosclerosis. The mechanisms of radiation-induced carotid atherosclerosis are still unclear and no previous study has investigated the genetic involvement of radiation-induced carotid atherosclerosis. The present study aims to determine the association between genetic polymorphisms and carotid atherosclerosis in patients treated with RT for nasopharyngeal carcinoma. The present study recruited 128 post-RT NPC patients. Carotid plaque score was assessed using ultrasonography. Thirteen single nucleotide polymorphisms (SNPs) that affect the function of anti-atherosclerotic genes, including SOD2, SOD3, CAT, PON1, PPARG, ADIPOQ, IL10, TGFB1 and NOS3, were genotyped. Association between the 13 SNPs and carotid atherosclerosis was evaluated using multiple regression after adjustment for covariates (PLINK). Multiple testing was corrected using Benjamini-Hochberg step-up false discovery rate controlling procedure. rs662 and rs705379 of PON1 were close to be significantly associated with carotid plaque score (Corrected P value, Pcor = 0.0528 and Pcor = 0.0842). When the two SNPs were combined together, TC haplotype in rs662-rs705379 of PON1 was significantly associated with higher carotid plaque score (Pcor < 0.05). None of the other SNPs showed significant association with carotid plaque score. TC haplotype in rs662-rs705379 of PON1 is likely to be a genetic risk factor of carotid plaque score. Post-RT NPC patients with the TC haplotype may need earlier and more frequent carotid ultrasound examinations for early detection of carotid atherosclerosis

    Full text: The prognosis of untreated hepatocellular carcinoma (HCC) is dismal with a median survival of less than two months having been reported. {sup 131}l labelled Lipiodol as a treatment for hepatocellular carcinoma (HCC) has been shown to be as efficacious as intraarterial chemotherapy but with less toxicity than chemotherapy. 23 patients (19 men and four women, mean age 69 years, range 28 to 80 years) with unresectable Okuda Stage I (n = 23) or 11 (n = 2) HCC were treated over a three-year period. All patients had biopsy proved HCC and had not received any prior therapy. Before therapy, all patients underwent CT scans of abdomen and thorax and scintigraphic bone scans to exclude extrahepatic disease. Further, CT scanning of the liver was performed following the hepatic artery injection of unlabelled Lipiodol to ensure that the HCC was Lipiodol avid. 1 GBq of {sup 131}l labelled Lipiodol was injected into the hepatic artery followed by CT liver scanning at day 1 and day 60 to calculate tumour response. Whole body scintigraphic scanning was performed on days 1 and 21 for dosimetry calculations. Ten patients had a second dose of {sup 131}l Lipiodol due either increasing serum alpha feto-protein levels and/or tumour progression on CT scanning. Minimal toxicity was seen with this dose regime. Survival time was estimated from the time of treatment by the Kaplan-Meier method. For Okuda I, the median survival length was 12 months with actuarial survival rates of 91 per cent, 65 per cent, 59 per cent and 20 per cent at 3,6,9,12 and 24 months respectively. All Okuda II patients died within five months. Iodine-131 Lipiodol therapy is well tolerated and may prolong survival in certain HCC patients.

    AIM: The aim of the study was to evaluate the predictive factors of survival in patients with locally advanced squamous cell esophageal carcinoma (LASCOC) treated with definitive chemoradiotherapy (CRT)regimen based on the 5FU/CDDP combination.METHODS: All patients with LASCOC treated with a definitive CRT using the 5FU/CDDP combination between 1994 and 2000 were retrospectively included.Clinical complete response (CCR) to CRT was assessed by esophageal endoscopy and CT-scan 2 mo after CRT completion. Prognostic factors of survival were assessed using univariate and multivariate analysis by the Cox regression model.RESULTS: A total of 116 patients were included in the study. A CCR to CRT was observed in 86/116 (74.1%).The median survival was 20 mo (range 2-114) and the 5-year survival was 9.4%. Median survival of responder patients to CRT was 25 mo (range 3-114) as compared to 9 mo (range 2-81) in non-responder patients (P <0.001). In univariate analysis, survival was associated with CCR (P < 0.001), WHO performance status < 2 (P= 0.01), tumour length < 6 cm (P = 0.045) and weight loss < 10% was in limit of significance (P = 0.053). In multivariate analysis, survival was dependant to CCR (P< 0.0001), weight loss < 10% (P = 0.034) and WHO performance < 2 (P = 0.046).CONCLUSION: Our results suggest that survival in patients with LASCOC treated with definitive CRT was correlated to CCR, weight loss and WHO performance status.

    From 1958 through 1980, 113 women with invasive squamous cell carcinoma of the vulva were treated with vulvectomy. Postoperative irradiation was given with cobalt-60 beam or 10 MV photons from a linear accelerator from anterior fields including the vulva and groins, with the intention of delivering 40-52 Gy with 2-4 Gy/day at a depth of 0.5 cm or 2 cm. The overall corrected five-year survival rate was 68%. The prognosis was shown to worsen significantly with advancing stages (I/96%, II/75%, III/62% and IV/19%), increasing grades (G1/78%, G2/70% and G3/22%) and increasing size of the tumor (T1/90%, T2/71% and T3/37%), as it also did when there were signs of vascular invasion, multifocal tumors or positive nodes in the inguinal regions. Recurrences were diagnoses in 32% of the patients. With the less aggressive surgical approach used, combined with radiation therapy to eradicate subclinical disease, the morbidity rate was acceptable and the survival rate comparable to that reported after more aggressive surgery.

    To evaluate the outcome of ductal carcinoma in situ (DCIS) patients who underwent surgery followed by radiation therapy (RT). We retrospectively reviewed 106 DCIS patients who underwent surgery followed by postoperative RT between 1994 and 2006. Ninety-four patients underwent breast-conserving surgery, and mastectomy was performed in 12 patients due to extensive DCIS. Postoperative RT was delivered to whole breast with 50.4 Gy/28 fx. Tumor bed boost was offered to 7 patients (6.6%). Patients with hormonal receptor-positive tumors were treated with hormonal therapy. The median follow-up duration was 83.4 months (range, 33.4 to 191.5 months) and the median age was 47.8 years. Ten patients (9.4%) had resection margin <1 mm and high-grade and estrogen receptor-negative tumors were observed in 39 (36.8%) and 20 (18.9%) patients, respectively. The 7-year ipsilateral breast tumor recurrence (IBTR)-free survival rate was 95.3%. Resection margin (<1 or ≥1 mm) was the significant prognostic factor for IBTR in univariate and multivariate analyses (p < 0.001 and p = 0.016, respectively). Postoperative RT for DCIS can achieve favorable treatment outcome. Resection margin was the important prognostic factor for IBTR in the DCIS patients who underwent postoperative RT.

    Full Text Available Solitary necrotic nodule of the liver is a rare benign lesion with a completely necrotic core and a hyalinized fibrotic capsule containing elastic fibers. The pathogenetic mechanism is still unclear. We here describe a case of SNN, whose central reticulin fibers within the nodule suggest the origin as hepatocellular carcinoma or other hepatocyte-origin tumors, treated with laparoscopic anatomical segmentectomy of the liver. A 76-year-old Japanese female, with no prior medical history and no symptom, visited our hospital with the heterogeneous hypoechoic lesion in the liver segment VI incidentally pointed out in abdominal ultrasonography. Computed tomography with contrast demonstrated a 1.1 cm sized low-density lesion with mild ring enhancement on the rim in the arterial phase. Since the possibility of malignant tumor with necrotic change could not be ruled out, she underwent laparoscopic anatomical segmentectomy of the liver. In the histological examination of the surgical specimen, the liver nodule was necrotic tissue without viable cells and signs of inflammation, which had fibrous capsule and central cystic change and showed trabecular pattern alignment of ghost cells and reticulin fibers orthogonal to the capsule. Also, the findings of chronic hepatitis were observed in the background liver.

    From 1958 through 1980, 113 women with invasive squamous cell carcinoma of the vulva were treated with vulvectomy. Postoperative irradiation was given with cobalt-60 beam or 10 MV photons from a linear accelerator from anterior fields including the vulva and groins, with the intention of delivering 40-52 Gy with 2-4 Gy/day at a depth of 0.5 cm or 2 cm. The overall corrected five-year survival rate was 68%. The prognosis was shown to worsen significantly with advancing stages (I/96%, II/75%, III/62% and IV/19%), increasing grades (G1/78%, G2/70% and G3/22%) and increasing size of the tumor (T1/90%, T2/71% and T3/37%), as it also did when there were signs of vascular invasion, multifocal tumors or positive nodes in the inguinal regions. Recurrences were diagnoses in 32% of the patients. With the less aggressive surgical approach used, combined with radiation therapy to eradicate subclinical disease, the morbidity rate was acceptable and the survival rate comparable to that reported after more aggressive surgery.

    Full Text Available Background and Purpose: Conventional portals, based on bony anatomy, for external beam radiotherapy for cervical cancer have been repeatedly demonstrated as inadequate. Conversely, with image-based conformal radiotherapy, better target coverage may be offset by the greater toxicities and poorer compliance associated with treating larger volumes. This study was meant to dosimetrically compare conformal and conventional radiotherapy. Materials and Methods: Five patients of carcinoma cervix underwent planning CT scan with IV contrast and targets, and organs at risk (OAR were contoured. Two sets of plans-conventional and conformal were generated for each patient. Field sizes were recorded, and dose volume histograms of both sets of plans were generated and compared on the basis of target coverage and OAR sparing. Results: Target coverage was significantly improved with conformal plans though field sizes required were significantly larger. On the other hand, dose homogeneity was not significantly improved. Doses to the OARs (rectum, urinary bladder, and small bowel were not significantly different across the 2 arms. Conclusion: Three-dimensional conformal radiotherapy gives significantly better target coverage, which may translate into better local control and survival. On the other hand, it also requires significantly larger field sizes though doses to the OARs are not significantly increased.

    In the past decade, a variety of interventional procedures have been employed for local control of hepatocellular carcinoma (HCC). These include transcather arterial chemoembolization (TACE) and several tumour ablation techniques, such as percutaneous ethanol injection (PEI),radio-frequency ablation (RFA), or percutaneous microwave coagulation therapy (PMC), laser-induced interstitial thermotherapy (LITT), etc. For a definite assessment of the therapeutic efficacy of interventional procedures,histological examination using percutaneous needle biopsy may be the most definite assessment of the therapeutic efficacy of interventional therapy, however, it is invasive and the specimen retrieved does not always represent the entire lesion owing to sampling errors. Therefore, computed tomography (CT) and magnetic resonance imaging (MRI) play a crucial role in follow-up of HCC treated by interventional procedures, by which the local treatment efficacy, recurrent disease and some of therapy-induced complications are evaluated. Contrast enhanced axial imaging (CT or MR imaging) may be the most sensitive test for assessing the therapeutic efficacy. The goal of the review was to describe the value of CT and MRI in the evaluation of interventional treatments.

    This study investigated the reasons for some patients requiring two consecutive sessions of percutaneous radiofrequency (RF) ablation of hepatocellular carcinoma (HCC). We reviewed our database of 1,179 patients (1,624 treatments) with HCCs treated by percutaneous ultrasound (US)-guided RF ablation over 6 years. We retrospectively evaluated 80 patients who required a second session after the first session. The medical records and follow-up CTs were studied. We assessed the reasons for the second session and the patient outcomes. A second session was required in 80 (4.8%) out of 1,642 treatments of percutaneous RF ablation for HCC. The reason for the second session included technical failure related to the patient or the procedure (n=26), technical failure due to residual (n=40), newly detected (n=11) or missed (n=3) tumors found at the immediate follow-up CT. All patients were retreated with a second RFA session the next day. Seventy-five (93%) of 80 patients achieved complete ablation after the second session. The remaining five patients were treated by TACE (n=1), additional RFA (as second treatment at next admission) (n=3), or were lost to follow-up (n=1). After 1 month follow-up, 72 patients (96%) showed complete ablation after the second session. The interventional oncologist should understand the technical reasons for a patient requiring a second session of RF ablation when providing treatment for HCCs and perform careful pre-procedural planning to minimize the need for multi-session procedures.

    Purpose: This study was designed to determine the technical feasibility, safety, efficacy, and potential to downstage patients to within transplantation criteria when treating patients with hepatocellular carcinoma (HCC) of the caudate lobe using Y90 radioembolization. Methods: During a 4-year period, 8 of 291 patients treated with radioembolization for unresectable HCC had disease involving the caudate lobe. All patients were followed for treatment-related clinical/biochemical toxicities, serum tumor marker response, and treatment response. Imaging response was assessed with the World Health Organization (WHO) and European Association for the Study of the Liver (EASL) classification schemes. Pathologic response was reported as percent necrosis at explantation. Results: Caudate lobe radioembolization was successfully performed in all eight patients. All patients presented with both cirrhosis and portal hypertension. Half were United Network for Organ Sharing (UNOS) stage T3 (n = 4, 50%). Fatigue was reported in half of the patients (n = 4, 50%). One (13%) grade 3/4 bilirubin toxicity was reported. One patient (13%) showed complete tumor response by WHO criteria, and three patients (38%) showed complete response using EASL guidelines. Serum AFP decreased by more than 50% in most patients (n = 6, 75%). Four patients (50%) were UNOS downstaged from T3 to T2, three of who underwent transplantation. One specimen showed histopathologic evidence of 100% complete necrosis, and two specimens demonstrated greater than 50% necrosis. Conclusions: Radioembolization with yttrium-90 appears to be a feasible, safe, and effective treatment option for patients with unresectable caudate lobe HCC. It has the potential to downstage patients to transplantation.

    Full Text Available Abstract Background Conventional cancer therapy including surgery, radiation, and chemotherapy often are physically debilitating and largely ineffective in previously treated patients with recurrent head and neck squamous cell carcinoma (SCC. A natural photochemical, hypericin, could be a less invasive method for laser photodynamic therapy (PDT of these recurrent head and neck malignancies. Hypericin has powerful photo-oxidizing ability, tumor localization properties, and fluorescent imaging capabilities as well as minimal dark toxicity. The current study defined hypericin PDT in vitro with human SCC cells before the cells were grown as tumor transplants in nude mice and tested as a model for hypericin induced tumor fluorescence and PDT via laser fiberoptics. Methods SNU squamous carcinoma cells were grown in tissue culture, detached from monolayers with trypsin, and incubated with 0.1 μg to 10 μg/ml of hypericin before exposure to laser light at 514, 550, or 593 nm to define optimal dose, time, and wavelength for PDT of tumor cells. The SCC cells also were injected subcutaneously in nude mice and grown for 6–8 weeks to form tumors before hypericin injection and insertion of fiberoptics from a KTP532 surgical laser to assess the feasibility of this operating room instrument in stimulating fluorescence and PDT of tumors. Results In vitro testing revealed a hypericin dose of 0.2–0.5 μg/ml was needed for PDT of the SCC cells with an optimal tumoricidal response seen at the 593 nm light absorption maximum. In vivo tumor retention of injected hypericin was seen for 7 to10 days using KTP532 laser induced fluorescence and biweekly PDT via laser fiberoptics led to regression of SCC tumor transplants under 0.4 cm2 diameter, but resulted in progression of larger size tumors in the nude mice. Conclusion In this preclinical study, hypericin was tested for 514–593 nm dye laser PDT of human SCC cells in vitro and for KTP532 surgical laser targeting

  18. Outcomes in Patients Treated With Mastectomy for Ductal Carcinoma In Situ

    International Nuclear Information System (INIS)

    Purpose: To examine, in a large, population-based cohort of women, the risk factors for recurrence after mastectomy for pure ductal carcinoma in situ (DCIS) and to identify which patients may benefit from postmastectomy radiation therapy. Methods and Materials: Data were analyzed for 637 subjects with pure DCIS, diagnosed between January 1990 and December 1999, treated initially with mastectomy. Locoregional relapse (LRR), breast cancer-specific survival, and overall survival were described using the Kaplan-Meier method. Reported risk factors for LRR (age, margins, size, Van Nuys Prognostic Index, grade, necrosis, and histologic subtype) were analyzed by univariate (log-rank) and multivariate (Cox modeling) methods. Results: Median follow-up was 12.0 years. Characteristics of the cohort were median age 55 years, 8.6% aged ≤40 years, 30.5% tumors >4 cm, 42.5% grade 3 histology, 37.7% multifocal disease, and 4.9% positive margins. At 10 years, LRR was 1.0%, breast cancer-specific survival was 98.0%, and overall survival was 90.3%. All recurrences (n=12) involved ipsilateral chest wall disease, with the majority being invasive disease (11 of 12). None of the 12 patients with recurrence died of breast cancer; all were successfully salvaged (median follow-up of 4.4 years). Ten-year LRR was higher with age ≤40 years (7.5% vs 1.5%; P=.003). Conclusion: Mastectomy provides excellent locoregional control for DCIS. Routine use of postmastectomy radiation therapy is not justified. Young age (≤40 years) predicts slightly higher LRR, but possibly owing to the small number of cases with multiple risk factors for relapse, a subgroup with a high risk of LRR (ie, approximately 15%) was not identified

  19. Prognostic factors for oral tongue carcinoma treated with intra-oral cone electron beam irradiation

    International Nuclear Information System (INIS)

    Twenty-five patients with squamous cell carcinoma of the oral tongue were treated with intra-oral cone electron beam irradiation (IOC) during the period from 1985 to 1995. We analyzed the prognostic factors for local control and complications. IOC was applied for T1 (16 cases) and T2 (9 cases) tumors. Hypofractionation was used for IOC (20, 10, or 8 Gy/fr, 1f/ wk). The total dose delivered ranged from 40 Gy to 78 Gy. Radiation dose homogenization was done through calculation of the normalized total dose (NTD) for α/β=10 (tumor) and α/β=3 (late normal tissue). The two-year local control rates for T1 and T2 were 80.4% and 77.8%, respectively. The two-year local control rates for patients whose overall treatment time (OTT) was ≤ 28 days (n=16) was 100% vs. 41.7% for patients whose OTT was >28 days (n=9) (p=0.002). Multivariate analysis was applied to identify possible prognostic factors for local control, OTT (p=0.02) was the only variable that significantly influenced local control. The incidence of radiation ulcer was 33.3% (7/21). Significant indicators of ulceration were fraction size (>>10 Gy) and NTD (α/β=3) (>>130 Gy) (p<0.05). These results indicate that prolonged OTT was the major reason for the failure of IOC radiotherapy to control local disease and that the relatively high rate of ulceration was due to large fraction size and high NTD (α/β=3).

    Since the introduction of combination antiretroviral therapy (ART), the life expectancy has increased for patients infected with human immunodeficiency virus (HIV). This has been associated with reductions in the incidences of some AIDS-defining malignancies, such as Kaposi sarcoma and non-Hodgkin lymphoma, but has coincided with an increased incidence of non-AIDS-defining malignancies, such as anal cancer. However, anal cancers are rare in patients with HIV in Japan. We report the case of an HIV-infected patient with anal cancer treated with chemoradiotherapy. A 37-year-old man receiving ART for HIV infection presented with a 1-month history of left inguinal lymphadenopathy and anal pain. Magnetic resonance imaging and computed tomography revealed a 56-mm mass, left inguinal lymphadenopathy, and left external iliac lymphadenopathy. The mass had infiltrated from the anal canal to the right levator ani and corpus spongiosum. Colonoscopy revealed a tumor with an ulcer in the anal canal. Histological examination of the tumor biopsy specimens confirmed the diagnosis of squamous cell carcinoma. The patient was diagnosed with anal cancer (T4N2M1 stage IV), and he received 5-fluorouracil (1000mg/m(2) on days 1-4 and 29-32) plus mitomycin C (10mg/m(2) on days 1 and 29) and concurrent radiotherapy (total dose, 59.4Gy in 33 fractions) along with ART. The treatment-related adverse events were grade 4 leukopenia and neutropenia, grade 3 thrombocytopenia, and grade 2 radiation dermatitis. Moreover, CD4 suppression was observed:the CD4 count decreased from 190 cells/μl before chemoradiotherapy to 138 cells/μl after 3 months, but increased to 210 cells/μl after 1 year. Because of the grade 4 leukopenia and neutropenia, the dose of 5-fluorouracil was reduced to 800mg/m(2) on days 29-32. A complete response was confirmed on magnetic resonance imaging, and colonoscopy confirmed the disappearance of the anal cancer. The patient is living with no signs of recurrence at 2 years

  2. Prognostic value of MRI-derived masticator space involvement in IMRT-treated nasopharyngeal carcinoma patients

    International Nuclear Information System (INIS)

    This retrospective study reassessed nasopharyngeal carcinoma (NPC) patients treated with intensity-modulated radiation therapy (IMRT), to determine the significance how magnetic resonance imaging (MRI)-derived masticator space involvement (MSI) affected patients’ prognosis. One thousand one hundred ninety seven NPC patients who had complete set of MRI and medical records were enrolled. Basing on their MRI findings, the T-categories of tumors were identified according to the seventh edition of American Joint Committee on Cancer staging system, which considers MSI a prognostic indicator for NPCs. Rates of overall survival (OS), local relapse-free survival (LRFS), regional relapse-free survival (RRFS) and distant metastasis-free survival (DMFS) were analyzed by the Kaplan-Meier method, and the Log-Rank test compared their differences. Cox regression analysis was employed to evaluate various prognostic factors systematically. Statistical analyses were conducted with SPSS 18.0 software, P value < 0.05 was considered statistically significant. Medial pterygoid muscle (MPM) was involved in 283 (23.64 %) cases, of which lateral pterygoid muscle (LPM) was concurrently affected in 181 (15.12 %) and infratemporal fossa (ITF) in 19 (1.59 %). Generally, MSI correlated with an OS, LRFS, and DMFS consistent with a T4-stage diagnosis (P > 0.05). Although different degrees of MSI presented a similar OS and DMFS (P > 0.1), tumors involving LPM had a relatively poorer LRFS than those affected the MPM only (P = 0.027), even for subgroup of patients composed of T3 and T4 classifications (P = 0.035). A tumor involving MPM brought an LRFS consistent with a T2 or T3-stage disease (P > 0.1). If the tumor affected LPM or ITF concurrently, the survival outcomes were more consistent with a T4-stage disease (P > 0.1). Nevertheless, compared to tumor infiltrating MPM, those invading LPM or ITF more frequently spread into other concurrent sites that earned higher T-staging categories. Moreover

    OBJECTIVE To study the effectiveness on the tumor load and cellular immune function of percutaneous cryoablation (argon-helium cryoablative system, AHCS) combined with transarterial chemoembolization (TACE) for treating large hepatocellular carcinomas (HCCs) with diameters over 10cm.METHODS A total of 48 HCC patients were treated with AHCS after TACE. Tumor sizes ranged from 10 to 14 cm. All cases were a hypervascular type. There were 38 Child A cases and 10 Child B cases. Forty were AFP positive and 8 negative. The patients were randomized with therapy group consisting of 26 cases and the control group 22 cases.The therapy group received AHCS 4 weeks following TACE treatment. Reexamination included pathology, tumor markers, T-lymphocyte subgroup levels and computed tomography or MRI. The necrosis rate of the tumor load was calculated by Cavalieri's theory. EORTC QLQ-C30 was used in quality of life evaluation.RESULTS The average tumor-load reduction rate (necrosis rate) was 8.07% after TACE, and 28.65% after AHCS. Coagulation necrosis was produced in the target area. The tumor markers deceased significantly after AHCS. Tumor-load reduction after AHCS was more significant than after TACE. Suppression of cellular immunity after TACE was significant.In contrast, CD3+, CD4+ and NK increased after AHCS and an abnormal T-lymphocyte distribution was corrected. Quality of life after AHCS increased according to the EORTC QLQ-C30 evaluation. No severe complications occurred.CONCLUSION Percutaneous AHCS cryoablation after TACE reduced the tumor load in the short term. At the same time, cellular immune function was increased after AHCS. TACE was critical in increasing the therapeutic efficacy of AHCS because of its embolisation of blood vessels preventing a Flow Effect. Reduction of the tumor load in the short term may conduce to increase cellular immunity. Percutaneous AHCS cryoablation combined with TACE can reduce the tumor load, improve cellular immunity and increase

    Objective: To study changes of NF-KB activity in colon carcinoma cell lines treated with different crude extracts of abrotani herba obtained through solvent extraction methods.Methods: Crude extracts of abrotani herba were extracted with ligarine, chloroform, acetoacetate and n-butanol in separating funnel.Exposure concentration of crude extracts were obtained through detecting viability of HT-29 cells by MTT.Then HT-29 cells and Lovo cells were treated with different crude extracts respectively.Changes of NF-KB activity in HT-29 cells and Lovo cells using different crude extracts were observed by EMSA.Results: Successfully extracted different crude extracts of abrotani herba and called them ligarine extract, chloroform extract,acetoacetate extract, n-butanol extract and remaining extract for short.NF-KB activity was significantly inhibited in HT-29 cells treated with chloroform extract, there were no significant differences in other groups compared with the control.The same change of NF-KB activity was observed in Lovo calls using different crude extracts of abrotani herba.Conclusion: NF-KB activity can be inhibited in colon carcinoma HT-29 calls and Lovo cells treated with chloroform extract obtained from abrotani herba through the method of solvent extraction.

  6. P53 and radiation response. The impact of oncogene activation in oesophagus carcinoma treated by radiotherapy only

    International Nuclear Information System (INIS)

    We studied a group of patients with locally advances oesophageal carcinoma, managed by radiotherapy exclusively, and determined the p53 protein expression by immunohistochemistry (IHC), in relationship to local control and survival. IHC for p53 protein was performed on paraffin-embedded specimens from 69 patients with adeno- and squamous cell carcinoma of the oesophagus. All patients were treated by external beam irradiation combined with intraluminal brachytherapy. Fifty-four percent (37/69) of the tumours showed overexpression of the p53 protein. No correlation with pretreatment parameters for p53-positive and p53-negative cases was detected. Overall survival as well as distant metastases-free survival was superior for p53 negative tumours. Local recurrence free-survival was slightly better in the p53 negative group, but this was dose dependent. (author)

  7. Squamous cell carcinoma of the floor of the mouth treated by radiotherapy

    International Nuclear Information System (INIS)

    Retrospective analysis was made of 110 cases of squamous cell carcinoma of the floor of the mouth. Age of the cases ranged from 34 to 86, with the mean value of 59.9 years. There was high sex preponderance to male(male: 93, female:17). Habitual heavy intake of alcohol and tobacco was also detected. Five- and 10-year survival rates according to Stages were; Stage I: 69%, 38%, Stage II: 40%, 20%, Stages III-IV: 33%, 15%, respectively. Local control rates by radiotherapy were; T1:80%, T2:56%, T3:17%. Small lesion tends to be localized to the floor of the mouth and was successfully controlled by implant without complication. As the size of the tumor increases, lesion tends to infiltrate into the ventral side of the mobile tongue, alveolar ridge of mandible as well as muscle of the floor and mandibular body. External radiotherapy of 3,000 cGy/3 weeks with concomitant i.v. injection of 90 mg of Bleomycin yielded remarkable reduction of mass size in most cases with T2, and complete disappearance of the tumor after sufficient period of follow-up in 21% of the cases treated. Among the complications attributable to radiotherapy, osteoradionecrosis was most common and serious and appeared in 13 out of 29 cases withou local recurrence after radiotherapy. Incidence of complications was higher in cases with linear-arrayed sources than with seed sources, higher in combined external and interstitial radiotherapy than in interstitial alone, and was higher in the dentulous cases than in the edentulous. Cases with positive nodes on first referral were 44(40%), of which 12 cases were later proved to be false during the clinical course. Fifteen N0 cases developed neck nodes during or after the treatment to the primary site which necessitated surgery. Prognosis was related to the surgical results of the neck. Homo- and contralateral submandibular, homolateral upper jugular, homolateral middle jugular nodes were the common sites involved. (author)

  8. Gastric carcinoma originating from the heterotopicsubmucosal gastric gland treated by laparoscopy andendoscopy cooperative surgery

    Institute of Scientific and Technical Information of China (English)

    2015-01-01

    Gastric carcinoma is derived from epithelial cells inthe gastric mucosa. We reported an extremely rarecase of submucosal gastric carcinoma originating fromthe heterotopic submucosal gastric gland (HSG) thatwas safely diagnosed by laparoscopy and endoscopycooperative surgery (LECS). A 66-year-old manunderwent gastrointestinal endoscopy, which detected asubmucosal tumor (SMT) of 1.5 cm in diameter on thelesser-anterior wall of the upper gastric body. The tumorcould not be diagnosed histologically, even by endoscopicultrasound-guided fine-needle aspiration biopsy. Localresection by LECS was performed to confirm a diagnosis.Pathologically, the tumor was an intra-submucosal welldifferentiated adenocarcinoma invading 5000 μm into the submucosal layer. The resected tumor had negativelateral and vertical margins. Based on the Japanesetreatment guidelines, additional laparoscopic proximalgastrectomy was curatively performed. LECS is a lessinvasive and safer approach for the diagnosis of SMT,even in submucosal gastric carcinoma originating fromthe HSG.

    Purpose: To compare clinical behaviors and treatment outcomes between patients with squamous cell carcinoma (SCC) and adenocarcinoma/adenosquamous carcinoma (AC/ASC) of the cervix treated with radical hysterectomy (RH) and adjuvant radiotherapy (RT) or concurrent chemoradiotherapy (CCRT). Methods and Materials: A total of 318 Stage IB-IIB cervical cancer patients, 202 (63.5%) with SCC and 116 (36.5%) with AC/ASC, treated by RH and adjuvant RT/CCRT, were included. The indications for RT/CCRT were deep stromal invasion, positive resection margin, parametrial invasion, or lymph node (LN) metastasis. Postoperative CCRT was administered in 65 SCC patients (32%) and 80 AC/ASC patients (69%). Patients with presence of parametrial invasion or LN metastasis were stratified into a high-risk group, and the rest into an intermediate-risk group. The patterns of failure and factors influencing survival were evaluated. Results: The treatment failed in 39 SCC patients (19.3%) and 39 AC/ASC patients (33.6%). The 5-year relapse-free survival rates for SCC and AC/ASC patients were 83.4% and 66.5%, respectively (p = 0.000). Distant metastasis was the major failure pattern in both groups. After multivariate analysis, prognostic factors for local recurrence included younger age, parametrial invasion, AC/ASC histology, and positive resection margin; for distant recurrence they included parametrial invasion, LN metastasis, and AC/ASC histology. Compared with SCC patients, those with AC/ASC had higher local relapse rates for the intermediate-risk group but a higher distant metastasis rate for the high-risk group. Postoperative CCRT tended to improve survival for intermediate-risk but not for high-risk AC/ASC patients. Conclusions: Adenocarcinoma/adenosquamous carcinoma is an independent prognostic factor for cervical cancer patients treated by RH and postoperative RT. Concurrent chemoradiotherapy could improve survival for intermediate-risk, but not necessarily high-risk, AC/ASC patients.

    International Nuclear Information System (INIS)

    Objective: To evaluate the clinical characteristics, outcome and prognostic factors of adolescent nasopharyngeal carcinoma. Methods: Between Jan 1990 and Dec 2009, totally 148 pathological confirmed nasopharyngeal carcinoma (NPC) patients with age ≤20 years were treated in our hospital, including stage II 8, stage III 58, stage IV 81, and unknown 1 when restaged by TNM system (UICC 2002), ninety-four (63.5%) patients were treated with radiotherapy alone, 54 (36.5%)patients were treated with radiotherapy combined with cisplatin-based chemotherapy. Results: The median follow-up time for all patients was 44.5 months. The 5-year overall survival (OS), local-regional control (LRC) and distant metastasis-free survival (DMFS) rates were 82.9%, 85.1% and 78.6%. There were 42 patients (28.4%) failed with 16 regional recurrence and 29 distant metastasis, and 3 with both; bone metastasis was the most common site of distant metastasis(22/29). In univariate analysis,the adverse prognostic factors for OS were stage T4(χ2=5.61, P=0.018), radiation dose 2=5.30, P=0.021), for LRC was radiation dose 2=4.24, P=0.039). In multivariate analysis, radiation dose 4 were the independent prognostic factors for OS (χ2=5.73, 5.56, P=0.017, 0.018), for LRC was radiation dose 2=5.81, P=0.016). Conclusions: The outcome of the present series was excellent, total nasopharyngeal radiation dose less than 70 Gy is inappropriate. Reduce the distant metastasis and late toxicities were the future direction for the treatment of adolescent nasopharyngeal carcinoma. (authors)

  12. Aggressive mammary carcinoma progression in Nrf2 knockout mice treated with 7,12-dimethylbenz[a]anthracene

    International Nuclear Information System (INIS)

    Activation of nuclear factor erythroid 2-related factor (Nrf2), which belongs to the basic leucine zipper transcription factor family, is a strategy for cancer chemopreventive phytochemicals. It is an important regulator of genes induced by oxidative stress, such as glutathione S-transferases, heme oxygenase-1 and peroxiredoxin 1, by activating the antioxidant response element (ARE). We hypothesized that (1) the citrus coumarin auraptene may suppress premalignant mammary lesions via activation of Nrf2/ARE, and (2) that Nrf2 knockout (KO) mice would be more susceptible to mammary carcinogenesis. Premalignant lesions and mammary carcinomas were induced by medroxyprogesterone acetate and 7,12-dimethylbenz[a]anthracene treatment. The 10-week pre-malignant study was performed in which 8 groups of 10 each female wild-type (WT) and KO mice were fed either control diet or diets containing auraptene (500 ppm). A carcinogenesis study was also conducted in KO vs. WT mice (n = 30-34). Comparisons between groups were evaluated using ANOVA and Kaplan-Meier Survival statistics, and the Mann-Whitney U-test. All mice treated with carcinogen exhibited premalignant lesions but there were no differences by genotype or diet. In the KO mice, there was a dramatic increase in mammary carcinoma growth rate, size, and weight. Although there was no difference in overall survival, the KO mice had significantly lower mammary tumor-free survival. Also, in the KO mammary carcinomas, the active forms of NF-κB and β-catenin were increased ~2-fold whereas no differences in oxidized proteins were observed. Many other tumors were observed, including lymphomas. Interestingly, the incidences of lung adenomas in the KO mice were significantly higher than in the WT mice. We report, for the first time, that there was no apparent difference in the formation of premalignant lesions, but rather, the KO mice exhibited rapid, aggressive mammary carcinoma progression

  14. Biological dosimetry study in differentiated thyroid carcinoma patients treated with 131Iodine

    International Nuclear Information System (INIS)

    Biological Dosimetry allows individual dose assessments based on the effect produced by ionizing radiation on a given biological parameter. The current biological endpoint being scored is chromosomal aberrations, relying on a lymphocytes culture from the patient's blood. The measured yield of chromosome aberrations is referred to a calibration curve obtaining the whole body dose. Different scenarios of overexposure can be taken into account by modifying the calculations leading to the dose estimate. Differentiated Thyroid Carcinoma patients undergo thyroidectomy followed by internal radiotherapy with 131I. The treatment's success entails the delivery of a lethal dose to the tumour within the maximum tolerable dose to a critical organ (blood doses over 2 Gy could lead to bone marrow depression). Currently, there is no established agreement for the selection of radioiodine dosage. Historically, the empiric approach, based on clinical and biochemical data, has been recommended. Nevertheless, this method may not be associated with optimal outcomes. On the other hand, the dosimetric approach attempts to determine the maximum allowable activity to be administered, establishing its biokinetics by a diagnostic 131I study. The methodology may be modified to further individualized treatment, however it requires validation. Biological dosimetry provides an independent measure of radiotherapy effect, as such it might aid in the validation process. Nonetheless, biological dosimetry has traditionally been applied in cases of external and accidental overexposure to ionizing radiation. Accordingly, it is mandatory to assess its value in medical internal incorporations (main objective of the present study). The applied treatment strategy comprises whole body dose assessment by biological and internal dosimetry in order to administer a personalized therapeutic activity. Overall, 20 patients with differentiated thyroid carcinoma were included in the study. For biological dosimetry

  15. Increased treatment-related mortality with additional cisplatin-based chemotherapy in patients with nasopharyngeal carcinoma treated with standard radiotherapy

    International Nuclear Information System (INIS)

    Background and purposes: We performed a meta-analysis of randomized controlled trials (RCTs) to determine the overall risk of treatment-related death associated with additional cisplatin-based chemotherapy in patients with nasopharyngeal carcinoma treated with standard radiotherapy. Material and methods: Eligible studies included RCTs in which cisplatin-based chemotherapy in combination with radiotherapy was compared with radiotherapy alone. Statistical analyses were conducted to calculate the summary incidence rates, relative risks (RRs), and 95% confidence intervals (CIs) using fixed- or random-effects models based on the heterogeneity of included studies. Results: A total of 2829 patients from 13 RCTs were included in this study. The overall incidence for treatment-related death in chemoradiotherapy and radiotherapy treated patients was 1.7% and 0.8%. Compared to radiotherapy alone, radiotherapy plus cisplatin-based chemotherapy significantly increased the risk of treatment-related mortality. On subgroup analyses, no difference was found in treatment-related mortality between different timings of chemotherapy and chemotherapeutic agents. Adding cisplatin-based chemotherapy was associated with higher incidences of severe acute toxicity. Conclusions: Cisplatin-based chemotherapy plus radiotherapy increased the risk of treatment-related death and severe acute toxicity, compared with radiotherapy alone. Better management of treatment toxicity might improve the therapeutic gain in patients with nasopharyngeal carcinoma.

    The outcomes of locoregionally advanced nasopharyngeal carcinoma patients treated with concurrent chemoradiation (CCRT) using intensity-modulated radiotherapy (IMRT) with/without neoadjuvant chemotherapy (NCT) were evaluated. Eighty-three patients who underwent NCT followed by CCRT (49%) or CCRT with/without adjuvant chemotherapy (51%) were reviewed. To the gross tumor, 67.5 Gy was prescribed. Weekly cisplatin was used as concurrent chemotherapy. With a median follow-up of 49.4 months, the 5-year local control, regional control, distant metastasis-free survival (DMFS), disease-free survival (DFS), and overall survival rates were 94.7%, 89.3%, 77.8%, 68.0%, and 81.8%, respectively. In multivariate analysis, the American Joint Committee on Cancer stage (p = 0.016) and N stage (p = 0.001) were negative factors for DMFS and DFS, respectively. Overall, NCT demonstrated no benefit and an increased risk of severe hematologic toxicity. However, compared to patients treated with CCRT alone, NCT showed potential of improving DMFS in stage IV patients. CCRT using IMRT resulted in excellent local control and survival outcome. Without evidence of survival benefit from phase III randomized trials, NCT should be carefully administered in locoregionally advanced nasopharyngeal carcinoma patients who are at high-risk of developing distant metastasis and radiotherapy-related mucositis. The results of ongoing trials are awaited.

    Full Text Available Portal vein tumor thrombosis (PVTT is a common complication of hepatocellular carcinoma (HCC and has a negative impact on prognosis. This characteristic feature led to the rationale of the present trial designed to assess the efficacy and the safety of yttrium-90 glass-microsphere treatment for advanced-stage lobar HCC with ipsilateral PVTT. 18 patients with unresectable lobar HCC and ipsilateral PVTT were treated in our institution with 90Y-microS radioembolization. Patients were evaluated every 3 to 6 months for response, survival, and toxicity. Mean follow-up was 13.0 months (2.2–50.6. Outcomes were: complete response (n=2, partial response (n=13, stable disease (n=1, and progressive disease (n=2 giving a disease control rate of 88.9%. Four patients were downstaged. Treating lobar hepatocellular carcinoma with ipsilateral portal vein thrombosis with yttrium-90 glass-microsphere radioembolization is safe and efficacious. Further clinical trials are warranted to confirm these results and to compare 90Y-microS with sorafenib, taking into account not only survival but also the possibility of secondary surgery for putative curative intention after downstaging.

  18. Seric thyroglobulin behavior in thyroid carcinoma patients treated with 131I

    International Nuclear Information System (INIS)

    The thyroid carcinomas, mainly the differentiated ones, for involving originally young patients and for showing relatively benign course, require a long term follow-up. So, every new available method that may be useful for the follow-up of these patients soon becomes very important. The advent of radioimmunoassay made the determination of thyroglobulin seric levels possible and this practice has been incorporated into medical routine in the past few years. The analysis of the results permit to conclude that the administration of 131I therapeutic dose to differentiated and medular thyroid carcinoma patients is followed by imediate and transitory rise in circulating thyroglobulin levels. It denotes immediate effect of the 131I that can be observed in a short period of time independently of L-T3 administration and endogen TSH levels. After this period the thyroglobulin is at least in a partial way, TSH-dependent. (author)

    This retrospective study aimed to evaluate the feasibility and effectiveness of radiofrequency ablation (RFA) in patients with solitary kidney for the treatment of renal cell carcinoma (RCC). Within 2 years 10 patients (seven males, three females; age 65 {+-} 8 years) were treated. All patients had a history of nephrectomy of the contralateral kidney. The indications for RFA were inoperability or high probability of complete renal failure after surgical enucleation of the tumor. 13 tumors with a size between 1.9 and 4.2 cm (average 2.7 cm) were treated. In patients with a tumor diameter larger than 2.5 cm a transarterial embolization was performed prior to RFA to reduce heat sink effect and risk of bleeding. Therapeutical success was defined as a lack of contrast enhancement in follow up examinations and shrinking of the treated area. Furthermore all patients' renal function was monitored. RFA of renal tumors under CT-fluoroscopy was feasible in all patients. Within the follow up (3 and 24 months) no tumor recurrence or major complication was detected. One patient developed another RCC and was successfully treated with a second RF-ablation. None of the patients developed renal failure with the need of hemodialysis. In one of the patients a hemorrhage into the surrounding tissue was noticed, which stopped spontaneously. RFA is a valuable and effective therapeutical option in patients with solitary kidney suffering from inoperable renal cell carcinoma. The complication rate is small and an excellent tumor control can be achieved without deterioration of the renal function.

    AIM: The prognosis of early gastric carcinoma (EGC) is generally excellent after surgery. The presence or absence of lymph node metastasis in EGC is an important prognostic factor. The survival and recurrence rates of node-negative EGC are much better than those of node-positive EGC. This study examined the factors related to lymph node metastasis in EGC to determine the appropriate treatment for EGC.

  4. Smoking is a poor prognostic factor for male nasopharyngeal carcinoma treated with radiotherapy

    International Nuclear Information System (INIS)

    Background and Purpose: To evaluate the effect of smoking on prognosis of male nasopharyngeal carcinoma by comparing the treatment outcomes between smokers and non-smokers. Materials and Methods: A total of 2450 nasopharyngeal carcinoma patients were enrolled, including 1865 male patients. Matching was performed between smokers and non-smokers in male patients according to age, UICC clinical stage, T stage, N stage and treatment. Survival outcomes were compared using Kaplan–Meier analysis and Cox regression. Smoking index was calculated by multiplying cigarette packs per day and smoked time (year). Results: In male patients, smokers had significantly lower 5-year overall survival (70.1% vs. 77.5%, P < 0.001) and locoregional recurrent free survival (76.8% vs.82.4%, P = 0.002) compared with non-smokers. Matched-pair analysis showed that smokers kept a high risk of death compared with non-smokers (HR = 2.316, P < 0.001). High degree of smoking index (>15 pack-years) had a poor effect on overall survival (HR = 1.225, P = 0.016). When smoking index was more than 45 and 60 pack-years, the risk for death increased to 1.498 and 1.899 fold compared with non-smokers (P = 0.040, 0.001), respectively. Conclusions: Smoking was a poor prognostic factor for male nasopharyngeal carcinoma. The heavier the patients smoked, the poorer prognosis they suffered

  5. Retrospective evaluation of dosimetric quality for prostate carcinomas treated with 3D conformal, intensity modulated and volumetric modulated arc radiotherapy

    International Nuclear Information System (INIS)

    This study examines and compares the dosimetric quality of radiotherapy treatment plans for prostate carcinoma across a cohort of 163 patients treated across five centres: 83 treated with three-dimensional conformal radiotherapy (3DCRT), 33 treated with intensity modulated radiotherapy (IMRT) and 47 treated with volumetric modulated arc therapy (VMAT). Treatment plan quality was evaluated in terms of target dose homogeneity and organs at risk (OAR), through the use of a set of dose metrics. These included the mean, maximum and minimum doses; the homogeneity and conformity indices for the target volumes; and a selection of dose coverage values that were relevant to each OAR. Statistical significance was evaluated using two-tailed Welch's T-tests. The Monte Carlo DICOM ToolKit software was adapted to permit the evaluation of dose metrics from DICOM data exported from a commercial radiotherapy treatment planning system. The 3DCRT treatment plans offered greater planning target volume dose homogeneity than the other two treatment modalities. The IMRT and VMAT plans offered greater dose reduction in the OAR: with increased compliance with recommended OAR dose constraints, compared to conventional 3DCRT treatments. When compared to each other, IMRT and VMAT did not provide significantly different treatment plan quality for like-sized tumour volumes. This study indicates that IMRT and VMAT have provided similar dosimetric quality, which is superior to the dosimetric quality achieved with 3DCRT

Herein, we developed magnetoliposomes containing recombinant human IFNα2b, designated as MIL, and evaluated this combination’s biological safety and therapeutic effect on both cellular and animal hepatocellular carcinoma models. Our data showed that MIL neither hemolyzed erythrocytes nor affected platelet-aggregation rates in blood. Nitroblue tetrazolium-reducing testing showed that MIL did not change the absolute numbers or phagocytic activities of leukocytes. Acute-toxicity testing also showed that MIL had no devastating effect on mice behaviors. All the results indicated that the nanoparticles could be a safe biomaterial. Pharmacokinetic analysis and tissue-distribution studies showed that MIL maintained stable and sustained drug concentrations in target organs under a magnetic field, helped to increase bioavailability, and reduced administration time. MIL also dramatically inhibited the growth of hepatoma cells. Targeting of MIL in the livers of nude mice bearing human hepatocellular carcinoma showed that MIL significantly reduced the tumor size to 38% of that of the control group. Further studies proved that growth inhibition of cells or tumors was due to apoptosis

    Full Text Available Hepatocellular carcinoma (HCC is one of the most commonly diagnosed cancers worldwide. Majority of patients with HCC are diagnosed in the advanced stages of disease and hence they are only suitable for palliative therapy. TACE (transarterial chemoembolization is the most commonly used treatment for unresectable HCC. It is however unclear if TACE improves the quality of life (QoL in patients with HCC. The aim of this review is to evaluate the impact of TACE on QoL of HCC patients.

    2016-03-01

    Full Text Available There have been major advances recently on the therapeutic approaches of hepatitis B virus (HBV-related hepatocellular carcinoma (HCC. Surgical treatments are the key curative treatments of HCC, whereas local ablative treatments may also achieve clinical remission in selected cases. Trans-arterial locoregional therapies are regarded as palliative but still lead to improved survival. There have been major breakthroughs in the systemic therapies for HCC. The first marketed targeted therapy, sorafenib, was shown to improve survival in patients with advanced HCC. Studies on other targeted therapies also showed promising results. Suppressing HBV with effective antiviral treatment would also benefit HCC patients by reducing recurrence and improving liver function.

    Primary squamous cell carcinoma (SCC) of the liver is rare. Totally nine such cases have been reported in the literature. Primary SCC of the liver has been reported to be associated with hepatic teratoma,hepatic cyst, or hepatolithiasis. Complete remission of poorly differentiated SCC of the liver could be achieved by systemic chemotherapy followed by surgery or remarkably respond to hepatic arterial injection of low dose chemotherapeutic drugs. Here we report the first case of primary SCC of the liver presenting as a solid tumor and receiving successful hepatic resection with 9-mo disease free survival.

  10. Experimental research on treating hepatic carcinoma by trans-arterial delivery of p53 gene mediated by lipsome combined transferring

    International Nuclear Information System (INIS)

    Objective: To investigate the trans-arterial delivery of p53 gene transfection efficiency and therapy effect on hepatic carcinoma in combination with transferrin mediated by liposome. Methods: Twenty-five VX2 experimental rabbits were randomly divided into five groups, and the different doses of transferrin combined with p53-LipofectAMINE complex were delivered into the hepatic arteries of the VX2 hepatic carcinoma models. The tissue protein of the carcinoma was extracted after 48 h and the transfection efficiency and expression rate of p53 gene were analyzed by western blot and immune histochemical techniques, to inspect the expression proportion of p53 with different doses transferring. Another ten VX2 were divided into two groups, recombinant plasmid p53-LipofectAMINE complex and transferrin-p53-LipofectAMINE complex were delivered into the hepatic arteries in two groups respectively. The liver function, size of the tumor and survival time of the animals was compared between the two groups, and results were analyzed statistically. Results: Semiquantitative analysis by Western Blot showed that the transfection and expression efficiency of p53 gene combined with transferrin were higher than those without it. By immune histochemical techniques, the p53 gene's positive rate of highly expression with various doses of transferrin were found to be different, and there was remarkable difference between the groups with and without transferring. They were 58.33%, 69.44%, 80.00%, 83.33%, 81.67% respectively, there was remarkable difference between the groups with and without transferring (Totality: χ2=42.37, P2 section: 3 groups as former χ2=4.82, P2=0.67, P<0.05). There was no statistical difference in the liver function at points of time between VX2 rabbits with and without transferring. But the tumor's sizes had significant difference at various points of time. Conclusion: Liposome-mediated p53 gene on treating hepatic carcinoma by trans-arterial gene delivery

    A 55-year-old man had been diagnosed with Wilson's disease and was treated with D-penicillamine 36 years earlier. He also had a 20-year history of psoriasis vulgaris and cyclosporine treatment. In 2012, a he presented with a hepatocellular carcinoma(HCC)that was removed via partial hepatic resection. In 2014, multiple HCC and a portal vein tumor thrombus were found in his posterior lobe. Sorafenib treatment was initiated. Cyclosporine treatment was continued. Three months later, abdominal enhanced CT revealed marked tumor reduction and shrinkage of the portal vein tumor thrombus. The therapeutic effect of sorafenib continued for 6 months. We did not observe deterioration in his psoriasis vulgaris and Wilson's disease for 9 months after sorafenib initiation.

  12. Outcomes and patterns of care of patients with locally advanced oropharyngeal carcinoma treated in the early 21st century

    International Nuclear Information System (INIS)

    We performed this study to assess outcomes of patients with oropharyngeal cancer treated with modern therapy approaches. Demographics, treatments and outcomes of patients diagnosed with Stage 3- 4B squamous carcinoma of the oropharynx, between 2000 – 2007 were tabulated and analyzed. The cohort consisted of 1046 patients. The 5- year actuarial overall survival, recurrence-free survival and local-regional control rates for the entire cohort were 78%, 77% and 87% respectively. More advanced disease, increasing T-stage and smoking were associated with higher rates of local-regional recurrence and poorer survival. Patients with locally advanced oropharyngeal cancer have a relatively high survival rate. Patients’ demographics and primary tumor volume were very influential on these favorable outcomes. In particular, patients with small primary tumors did very well even when treatment was not intensified with the addition of chemotherapy

  13. Anal carcinoma – Survival and recurrence in a large cohort of patients treated according to Nordic guidelines

    International Nuclear Information System (INIS)

    Objective: To evaluate treatment outcome in a large population-based cohort of patients with anal cancer treated according to Nordic guidelines. Material: Clinical data were collected on 1266 patients with anal squamous cell carcinoma diagnosed from 2000 to 2007 in Sweden, Norway and Denmark. 886 of the patients received radiotherapy 54–64 Gy with or without chemotherapy (5-fluorouracil plus cisplatin or mitomycin) according to different protocols, stratified by tumor stage. Results: High age, male gender, large primary tumor, lymph node metastases, distant metastases, poor performance status, and non-inclusion into a protocol were all independent factors associated with worse outcome. Among patients treated according to any of the protocols, the 3-year recurrence-free survival ranged from 63% to 76%, with locoregional recurrences in 17% and distant metastases in 11% of patients. The highest rate of inguinal recurrence (11%) was seen in patients with small primary tumors, treated without inguinal irradiation. Conclusions: Good treatment efficacy was obtained with Nordic, widely implemented, guidelines for treatment of anal cancer. Inguinal prophylactic irradiation should be recommended also for small primary tumors

    The dose-time factors in the external beam treatment of 473 patients with squamous cell carcinoma of the pharyngeal wall, vocal cord, pyriform sinus or supraglottic larynx were considered. The effect of overall treatment time on the tumor response was quantified by estimating the increment in dose per day needed to achieve a constant rate of local constant rate of local control, that is, the dose required to counterbalance the effect of growth of the tumor during irradiation. The estimated increment in isoeffect dose per day varies between sites, however, the increments, although estimated with considerable uncertainty, are in general larger than 1 Gy per day. These estimates are consistent with accelerated tumor clonogen repopulation during irradiation. (author). 8 refs.; 6 figs.; 10 tabs.

  16. Radiation myelopathy in patients treated for carcinoma of bronchus using a six fraction regime of radiotherapy

    International Nuclear Information System (INIS)

    The adoption of a six-fraction regime of radiotherapy for patients with locally advanced carcinoma of the bronchus was followed by the appearance of radiation myelitis in eight cases. These were among a group of 130 patients given radiotherapy with anterior and posterior treatment fields, without shielding of the spinal cord. Radiation myelitis was found only in those where the calculated spinal-cord dose exceeded 3350 cGy(rad). The possible precipitating factors in the eight patients who suffered myelopathy were compared with those in the remaining 62 patients who also received spinal-cord doses calculated to be greater than 3350 cGy(rad). Only one difference was found - the haemoglobin concentration was significantly higher in those who suffered neuropathy compared with those who did not (P=0.05). (U.K.)

    本文报道了一例单纯中药治愈弥漫性肝癌的病案。患者于2011年6月因肝区疼痛就诊,强化CT检查示肝脏多发占位,弥漫整个肝右叶,最大占位结节直径达5cm,考虑肝癌。患者自发病以来未进行任何西医抗肿瘤治疗,于2011年6月至2014年8月单纯接受中药治疗。2014年11月18日末次随访,患者一般状况良好,肿瘤病灶消失,恢复正常生活。%We reported a detailed clinical course of complete response of hepatocellular carcinoma(HCC) with traditional Chinese medicine(TCM) treatment in the present study. In June 2011, a 47-year-old man was admitted to our hospital for multiple mass lesions in liver. Abdominal contrast-enhanced CT revealed multiple low density nodules with heterogeneous enhancement in his right lobe of the liver and the largest nodule diameter was about 5 cm. The clinical diagnosis was hepatocellular carcinoma (diffuse-type). Resection was not performed considering the patient’s poor physical condition. He received THM therapy as an alternative. One months later, CT showed that the majority lesions of the right liver lobe shrank. In November 2014, CT showed that the liver lesions completely disappeared and had no evidence of tumor recurrence. Our case provides additional evidence to show that TCM treatment is effective for patients with HCC, and it can achieve complete remission, long disease-free survival and provide patients with good quality of life.

    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

  20. Recurrent rectal carcinoma treated with high dose rate intraluminal Brach therapy

    International Nuclear Information System (INIS)

    A 65 years old man with recurrent rectal cancer was treated with remote after loading High Dose Rate Intraluminal Brach therapy (HDRILB). After eight weeks of HDRILB there was complete regression of the tumor. Bleeding per rectum and pain in the perineum were greatly improved. He died of myocardial infarction after 41 months of treatment with HDRILB. The treated lesions were incomplete remission at the time of death. The procedure was well tolerated. The only treatment associated toxicity was grade 2 proctitis, which was treated conservatively. HDRILB can be used as one of the treatment options in patients with recurrent rectal cancers who have undergone previous abdominal surgery and external beam irradiation, as exhibited in our limited experience.(author)

    Full Text Available Abstract Background Tyrosine kinase inhibitors (TKIs are currently approved for the treatment of metastatic renal cell carcinoma (mRCC. The cardiotoxic effects of sorafenib and sunitinib may cause hypertension, left ventricular ejection fraction (LVEF dysfunction and/or congestive heart failure (CHF, and arterial thrombo-embolic events (ATE. Only three cases of coronary artery disease related to sorafenib therapy have been described in the literature, and all were due to arterial vasospasm without evidence of coronary artery stenosis on angiography. Cardiotoxicity is commonly associated with the presence of cardiovascular risk factors, such as a history of hypertension or coronary artery disease. Case presentation We describe a patient who experienced an unusual cardiac event after 2 years of sorafenib treatment. A 58-year-old man with mRCC developed acute coronary syndrome (ischemia/infarction associated with critical sub-occlusion of the common trunk of the left coronary artery and some of its branches, which was documented on coronary angiography. The patient underwent triple coronary artery bypass surgery, and sorafenib treatment was discontinued. He did not have any cardiovascular risk factors, and his cardiac function and morphology were normal prior to sorafenib treatment. Conclusions Further investigation of a larger patient population is needed to better understand cardiac damage due to TKI treatment. Understanding the usefulness of careful cardiovascular monitoring might be important for the prevention of fatal cardiovascular events, and to avoid discontinuation of therapy for the underlying cancer.

    2015-05-01

    Full Text Available Sorafenib exerts modest antitumor activity in patients with advanced hepatocellular carcinoma (HCC, and radiological progressive disease (rPD does not always correspond to so-called clinical progressive disease (cPD. We evaluated 101 patients who initiated sorafenib treatment for HCC and assessed post-progression survival (PPS using the Cox proportional hazards model. PPS was calculated from the date of the first rPD until the date of death or the last follow-up. Using Cox model analysis of the 76 patients who experienced first rPD, we identified the Child-Pugh class, Eastern Cooperative Oncology Group performance status, the best antitumor response during treatment (using Response Evaluation Criteria in Solid Tumors (RECIST Version 1.1 and α-fetoprotein levels as independent factors affecting PPS. When these factors were used to define scores ranging from zero to five with a cutoff value of two, PPS of patients who received best supportive care (BSC after rPD was not statistically significantly different from that of patients who received post-rPD therapy with scores ≥2 (p = 0.220. In contrast, the PPS for the post-rPD therapy group was significantly longer compared with the BSC patients with scores <2 (p < 0.001. Patients who scored ≥2 at their first rPD were judged cPD and as candidates for BSC.

    The aims of the study were to: (1) examine levels of trismus, xerostomia and nutritional status; (2) compare levels of trismus, xerostomia and nutritional status in patients with nasopharyngeal carcinoma (NPC) receiving different types of radiation modalities; and (3) identify factors related to NPC survivors' risk status for malnutrition and existing malnutrition. A cross-sectional study with consecutive sampling was conducted. NPC survivors were recruited from otolaryngology/oncology outpatient clinics in a medical centre in Northern Taiwan. Study measures included (1) Mandibular Function Impairment Questionnaire, (2) Xerostomia Questionnaire, (3) Mini Nutrition Assessment, (4) Hospital Anxiety and Depression Scale - Depression subscale, and (5) Symptom Severity Scale. A total of 110 subjects were recruited. Those receiving intensity-modulated radiation therapy had less trismus and xerostomia than patients receiving two-dimensional radiation therapy. Patients with female gender, advanced stage, completion of treatments within 1 year, higher levels of depression, more severe trismus and higher symptom severity tended to have malnutrition or were at risk of malnutrition. Trismus and xerostomia are long-term problems in some NPC survivors and may contribute to malnutrition. To better manage a patient's trismus and xerostomia and to enhance nutritional status, clinicians should develop a patient-specific care programme based on careful assessment and targeted measures to improve oral function and insure adequate nutritional intake.

    Objectives. The aim was to compare demographics and pathological features of bladder carcinoma treated in a urology unit with findings of previous studies done in Sri Lanka. Materials and Methods. Data of newly diagnosed patients with bladder cancer in a tertiary referral centre from 2011 to 2014 were analysed. Data on bladder cancers diagnosed from 1993 to 2014 were obtained from previous publications and Sri Lanka Cancer Registry. Results. There were 148 patients and mean age was 65 years. Male to female ratio was 4.1 : 1. Urothelial carcinoma (UC) was found in 89.2% of patients. Muscle invasion was noted in 35% of patients compared to 48.4% two decades ago. In patients with UC, 16.5% were found to have pT1 high grade tumour. It was 5.3% from 1993 to 2000. Pure squamous cell carcinoma was found in 8.1% of patients while primary or de novo carcinoma in situ (not associated with high grade pT1 tumours) was seen in one patient only. Conclusions. The percentage of squamous carcinoma is higher among Sri Lankan patients while primary carcinoma in situ is a rarity. The percentage of muscle invasive disease has decreased while the percentage of pT1 high grade tumours has increased during the last two decades in Sri Lanka. PMID:26884756

    2011-01-01

    Full Text Available During thyroid tumor progression, cellular de-differentiation may occur and it is commonly accompanied by metastatic spread and loss of iodine uptake. Retinoic acid (RA administration might increase iodine uptake in about 40% of patients, suggesting that RA could be a promising therapeutic option for radioiodine non-responsive thyroid carcinoma, although a prospective study with a long-term follow-up has not been reported. This was a clinical prospective study assessing the value of 13-cis-RA in patients with advanced thyroid carcinoma and its impact on major outcomes such as tumor regression and cancer-related death with a long-term follow-up of patients submitted to radioiodine (131I therapy after RA administration. Sixteen patients with inoperable disease and no significant radioiodine uptake on post-therapy scan were selected. Patients were treated orally with 13-cis-RA at a dose of 1.0 to 1.5 mg·kg-1·day-1 for 5 weeks and then submitted to radioiodine therapy (150 mCi after thyroxine withdrawal. A whole body scan was obtained 5 to 7 days after the radioactive iodine therapy. RECIST criteria were used to evaluate the response. An objective partial response rate was observed in 18.8%, a stable disease rate in 25% and a progression disease rate in 56.2%. Five patients died (62.5% in the group classified as progression of disease. Progression-free survival rate (PFS ranged from 72 to 12 months, with a median PFS of 26.5 months. RA may be an option for advanced de-differentiated thyroid cancer, due to the low rate of side effects.

  8. Factors related to lymph node metastasis and surgical strategy used to treat early gastric carcinoma

    AIM: The prognosis of early gastric carcinoma (EGC) is generally excellent after surgery. The presence or absence of lymph node metastasis in EGC is an important prognostic factor. The survival and recurrence rates of node-negative EGC are much better than those of node-positive EGC. This study examined the factors related to lymph node metastasis in EGC to determine the appropriate treatment for EGC.METHODS: We investigated 748 patients with EGC who underwent surgery between January 1985 and December 1999 at the Division of Gastroenterologic Surgery, Department of Surgery, Chonnam National University Hospital. Several clinicopathologic factors were investigated to analyze their relationship to lymph node metastasis: age, sex, tumor location, tumor size, gross type, histologic type, depth of invasion, extent of lymph node dissection, type of operation,and DNA ploidy.RESULTS: Lymph node metastases were found in 75 patients (10.0%). Univariate analysis showed that male sex, tumor size larger than 2.0 cm, submucosal invasion of tumor, histologic differentiation, and DNA ploidy pattern were risk factors for regional lymph node metastasis in EGC patients. However, a multivariate analysis showed that three risk factors were associated with lymph node metastasis:large tumor size, undifferentiated histologic type and submucosal invasion. No statistical relationship was found for age, sex, tumor location, gross type, or DNA ploidy in multivariate analysis. The 5-year survival rate was 94.2% for those without lymph node metastasis and 87.3% for those with lymph node metastasis, and the difference was significant (P<0.05).CONCLUSION: In patients with EGC, the survival rate of patients with positive lymph nodes is significantly worse than that of patients with no lymph node metastasis. Therefore,a standard D2 lymphadenectomy should be performed in patients at high risk of lymph node metastasis: large tumor size, undifferentiated histologic type and submucosal invasion.

  9. Lacrimal Sac Mucoepidermoid Carcinoma with Metastases to the Cavernous Sinus Following Dacryocystorhinostomy Treated with Stereotactic Radiotherapy

    Directory of Open Access Journals (Sweden)

    2016-05-01

    Full Text Available Purpose: We report a very good outcome in a 44-year-old woman in whom cancer was missed as the cause of nasolacrimal duct obstruction and dacryocystitis and which was deemed inoperable after spreading to the cavernous sinus. Case Report: The patient was referred to our unit 12 months following uneventful right dacryocystorhinostomy for nasolacrimal duct obstruction. This had been complicated by the formation of a significant canthal swelling 6 months later, which had been excised at that time. The symptom of nasolacrimal duct obstruction and scar recurrence prompted the referral to our unit. Examination and biopsy confirmed a malignancy. Despite extensive surgery, including concurrent radical neck dissection and parotidectomy, within 6 months, her mucoepidermoid carcinoma was found to have spread to the cavernous sinus, restricting blood flow from the carotid and causing an abducens nerve palsy. Though deemed inoperable at first, Gamma Knife stereotactic radiosurgery was sought as treatment for her disease, resulting in a good outcome 4 years after surgery. Conclusion: Experience from this case suggests the importance of considering malignancy as a cause in young patients when presenting with nasolacrimal duct obstruction. In such cases, and perhaps for all patients, biopsy specimens should be submitted as many tumours are found incidentally at the time of dacryocystorhinostomy. Whilst the external approach to dacryocystorhinostomy may identify abnormal anatomy intraoperatively, prompting biopsy, this is less likely with an endonasal approach where osteotomy precedes sac visualisation. The endonasal approach may therefore be less appropriate in such cases where malignancy is suspected as osteotomy may aid in the spread.

    A 50-year-old man presented to our hospital with the chief complaint of right hypochondriac pain and a palpable tumor. Advanced hepatocellular carcinoma (HCC) and chronic hepatitis B infection were diagnosed and treated by twice-repeated transcatheterarterial chemoembolization (TACE) followed by administration of entecavir. Two months after the last TACE, alpha-fetoprotein(AFP)and protein induced by vitamin K absence or antagonistII (PIVKA-II) levels had elevated, and multiple small early enhancing nodules were detected on computed tomography(CT)scan. Based on his age and liver function (Child-Pugh score A5), a full dose of sorafenib (800 mg/day) was administered. The sorafenib dose was decreased after one month to 400mg/day because of hand-foot syndrome. Following sorafenib administration, the lesions shrank markedly, and complete response (CR) according to modified Response Evaluation Criteria In Solid Tumors(mRECIST)was achieved within 4 months. Six months after sorafenib treatment was begun, recurrent HCC was detected in segment 6, near the previously treated lesion. The decreased size of the main tumor and normalization of AFP levels allowed curative surgical resection. The patient was discharged 5 days after surgery and is currently treated with a half dose of sorafenib. Thirteen months after surgery, a small early enhancing lesion is visible on postoperative CT scan, but AFP and PIVKA-II levels are still keeping in a normal range. This case demonstrates that if sorafenib treatment is effective, then subsequent surgical treatment can be reconsidered in patients with advanced HCC responding to this combined therapy.

    2014-04-01

    Purpose: To examine the outcomes of Southeast Asian (SEA) women with low-risk ductal carcinoma in situ (DCIS) treated with breast-conserving surgery (BCS) and adjuvant radiation therapy. Methods and Materials: Retrospective chart reviews of patients treated with BCS for DCIS from 1995 to 2011 were performed. Patients meeting the selection criteria from Eastern Cooperative Oncology Group 5194 were included. Most patients received adjuvant radiation therapy (RT) consisting of whole-breast RT delivered to 50 Gy followed by a 10-Gy boost to the tumor bed. Results: Of 744 patients with pathologic diagnosis of pure DCIS identified, 273 met the selection criteria: low-intermediate grade (LIG), n=219; high grade (HG), n=54. Median follow-up for these patients was 60 months. There were 8 ipsilateral breast tumor recurrences (IBTRs) in total, 7 of which were DCIS. The estimated actuarial IBTR rates at 5 and 10 years for the entire cohort are 1.8% and 4.3%, respectively. Of the 219 patients with LIG DCIS, 210 received RT and 9 did not. There were 7 IBTRs in LIG DCIS, 2 among the 9 patients who did not receive RT. The IBTR rates in LIG DCIS at 5 and 10 years are 2.3% and 4.2%, respectively. All patients with HG DCIS received RT. There was only 1 IBTR occurring beyond 5 years, giving an estimated IBTR rate of 4.5% at 10 years. Conclusions: SEA women with screen-detected DCIS have exceedingly low rates of IBTR after BCS, comparable to that observed in reports of similar patients with low-risk DCIS treated with adjuvant radiation.

  12. Analysis of late toxicity in nasopharyngeal carcinoma patients treated with intensity modulated radiation therapy

    International Nuclear Information System (INIS)

    To observe the late toxicities in nasopharyngeal carcinoma (NPC) patients who achieved long-term survival after intensity modulated radiation therapy (IMRT). 208 untreated NPC patients who received IMRT and survived more than five years with locoregional disease control and no metastasis were evaluated in this study. The prescription dose to the gross target volume of nasopharynx (GTVnx), positive neck lymph nodes (GTVnd), clinical target volume 1 (CTV1) and 2 (CTV2) was 68Gy/30f, 60-66Gy/30f, 60 Gy/30f and 54Gy/30f, respectively. The nasopharynx and upper neck targets were irradiated using IMRT, and the lower neck and supraclavicular fossae targets were irradiated using the half-beam technique with conventional irradiation. The late toxicities were evaluated according to the LENT/SOMA criteria of 1995. The median follow-up time was 78 months (60–96 months). The occurrence rates of cervical subcutaneous fibrosis, hearing loss, skin dystrophy, xerostomia, trismus, temporal lobe injury, cranial nerve damage, cataract, and brain stem injury induced by radiotherapy were 89.9%, 67.8%, 47.6%, 40.9%, 7.21%, 4.33%, 2.88%, 1.44%, and 0.48%, respectively. No spinal cord injury and mandible damage were found. Grade 3–4 late injuries were observed as follows: 1 (0.48%) skin dystrophy, 4 (1.92%) cervical subcutaneous fibrosis, 2 (0.96%) hearing loss, 2 (0.96%) cranial nerve palsy, and 1 (0.48%) temporal lobe necrosis. No grade 3–4 late injuries occurred in parotid, temporomandibular joints and eyes. Xerostomia decreased gradually over time and then showed only slight changes after 4 years. The change in the incisor distance stabilised by 1 year after RT, however, the incidence of hearing loss, skin dystrophy, subcutaneous fibrosis and nervous system injuries increased over time after RT. The late injuries in most NPC patients who had long-term survivals after IMRT are alleviated. Within the 5 years of follow-up, we found xerostomia decreased gradually; The change in the

    International Nuclear Information System (INIS)

    Objective: The want of study about the effect of definitive radiotherapy (RT) on sexual function for nasopharyngeal carcinoma (NPC) led to this investigation. This was designed as a pilot study to assess the patterns of sexual dysfunction and its prevention. Methods: Based on the SOMA/LENT toxicity criteria, a standardized questionnaire was designed to investigate the following sexual performances: desire, satisfaction, erectability, orgasm and frequency of sex in the two years before and after radiotherapy with each patient serving as his or her own control. Ninety patients (66 male, 24 female) were included into this study. Reduction of libido, satisfaction with sex, erectability, resumption of sex after radiotherapy, intensity of orgasm, frequency of sex and the subjective assumption of sex dysfunction by the patient were all entered and analyzed by the SOMA/LENT. Occupation: 27 workers, 39 farmers, 10 civil servants and 14 businessmen. Thirteen patients had had high school education or above, while the other 77 were on lower level. Results: All patients could remember the time of first sexual activity after treatment, 45 of them after 3 months, 71 after one year and 4 patients ceased sex at all. Fifteen patients were able to resume sex one year after radiotherapy. As for the quality of the sexual activity, 34 (37.8%) patients noted a decline in libido, 36 (40.0%) were dissatisfied with their sex and 5(7.6%) of the 66 male patients developed new impotence and 27 (30.0%) complained of lowered intensity of orgasm. The sexual frequency in this cohort was (1.271±0.877) times/ week before and (0.691±0.854) times/ week after the treatment. Sixty-four (71.1%) patients experienced a frequency diminution. Only 15 experienced no change in their sex. Statistical analysis did not show any significant relation between kinds of profession, education level or economic status and sexual dysfunction, subjective perception. However, subjective perception had a significant

  14. Retrospective Analysis of Local Control and Cosmetic Outcome of 147 Periorificial Carcinomas of the Face Treated With Low-Dose Rate Interstitial Brachytherapy

    International Nuclear Information System (INIS)

    Purpose: Skin cancer is the most common malignancy in white populations. We evaluated the local cure rate and cosmetic outcome of patients with basal cell carcinoma (BCC) or squamous cell carcinoma (SCC) of the face treated with low-dose rate brachytherapy. Methods and Materials: Between February 1990 and May 2000, 147 facial carcinomas in 132 patients were treated by 192Ir wire implantation. Side effects of brachytherapy were noted. Follow-up was 2 years or more. Locoregional recurrence-free survival (LRFS) and overall survival were recorded. Group A included patients treated by primary brachytherapy, and Group B included those treated after recurrence. Results: A total of 121 carcinomas were BCCs (82.3%) and 26 were SCCs (17.7%); the median tumor size was 10 mm. Of the tumors, 86 (58.5%) were in men and 61 (41.5%) were in women; the median age was 71 years. Group A comprised 116 lesions (78.9%), and Group B, 31 (21.1%). There were 17 relapses (11.6%) after a median follow-up of 72 months: 12 local, 4 nodal, and 1 local and nodal. Locoregional-free survival was 96.6% at 2 years and 87.3% at 5 years. Five-year LRFS was 82.6% in men and 93.3% in women (p = 0.027). After adjustment for gender, LRFS was better after primary treatment than after recurrence (hasard ratio HR, 2.91; 95% confidence interval, 1.06-8.03; p = 0.039). Five-year LRFS was 90.4% for BCC and 70.8% for SCC (p = 0.03). There were no Grade 3 complications. Conclusions: Low-dose rate brachytherapy offers good local control and cosmetic outcome in patients with periorificial skin carcinomas, with no Grade 3 complications. Brchytherapy is more efficient when used as primary treatment.

  16. Tumor volume is an independent prognostic indicator of local control in nasopharyngeal carcinoma patients treated with intensity-modulated radiotherapy

    International Nuclear Information System (INIS)

    To retrospectively analyze whether primary tumor volume and primary nodal volume could be considered independent prognostic factors for nasopharyngeal carcinoma treated with intensity-modulated radiation therapy. Three hundred sixty-three consecutive nasopharyngeal carcinoma (NPC) patients who were stage I-IVa+b and treated with intensity-modulated radiotherapy (IMRT) in our center from October 2003 to October 2005 were analyzed retrospectively. The predictive ability of gender, age, T and N stage, combined chemotherapy, primary tumor and nodal volume for the 5-year local control (LC), distant-metastasis free survival (DMFS) and overall survival (OS) rate were investigated. Primary tumor and nodal volume were measured based on registration of magnetic resonance imaging (MRI) with contrast-enhanced computed tomography (CT) images. The Kaplan–Meier method was used for survival analysis, the log-rank test was used for univariate analyses and the Cox proportional hazard model was used for multivariate prognostic analyses. The mean value of primary tumor and nodal volume were 31.5 ml and 9.7 ml. The primary tumor and nodal volume were respectively divided into four groups for analysis (primary tumor volume: TV1≤20 ml, 2040 ml; primay nodal volume: NV1≤5 ml, 520 ml). In univariate analysis, the 5-year LC and DMFS rate for TV4 was significantly decreased compared to the other groups (LC: p<0.001, DMFS: p=0.001), the 5-year OS rate for TV3 and TV4 were significantly decreased compared to other two subgroups (p=0.002) and the 5-year regional control (RC), DMFS and OS rate for NV3 and NV4 were significantly less than NV1 and NV2 (RC: p=0.002, DMFS: p=0.01, OS: p=0.014). Multivariate analysis showed that TV>40 ml was an adverse prognostic factor for the 5-year local regional control (LRC) rate (RR 2.454, p=0.002). Primary nodal volume had no statistical significance in predicting 5-year LRC, DMFS and OS

    International Nuclear Information System (INIS)

    The administration of I-131 to patient with Differentiated Thyroid Carcinoma (CaDiT) it is used inside the therapeutic outline as later step to the thyroidectomy. However, the good activity to give is of difficult determination due to factors such as, the variability in the capacity of tumoral reception of the I-131, distribution of the pharmaceutical, physiologic status, other associate pathologies, grade of advance of the illness, and previous treatments. Additionally, the activity to administer is dependent of the dose of tolerance in the healthy tissues; superior dose to 2 Gy in bone marrow, its could drive to myelotoxicity. At the moment, the form more extended of administration it is the empiric prescription that considers clinical parameters and of laboratory for their determination. Presently work, the protocol of applied treatment incorporates the evaluation for internal dosimetry and biological dosimetry to estimate absorbed dose in bone marrow. The biological estimate of the dose of these patients is based on the quantification of chromosomal aberrations whose frequency is referred to a curve-dose response in which the lymphocytes is irradiated in vitro with I-131, allowing to determine the in vivo dose to the patient's circulating lymphocytes. The objective of the present work is to determine the applicability of different cytogenetic essays in the estimate of the absorbed dose to the whole body or specific organs. Three patients were evaluated with CaDiT. Their treatment protocol consisted on a tracer administration of radioactive iodine of 74 - 111 MBq (2 - 3 mCi) and a therapy 7,4 - 11,1 GBq (200 - 300 mCi). Previous to the tracer administration and 8 days post-therapeutic administration took samples of veined blood that were evaluated by biological dosimetry by means of the application of the techniques: conventional cytogenetic Micronucleus and FISH (Hybridization in situ by Fluorescence). Starting from the frequencies of observed chromosomal

    Full Text Available Abstract Background Chronic hepatitis B virus (HBV and hepatitis C virus (HCV are established causes of HCC. HCC patients are often diagnosed late and receive palliative therapies, however, the survival of Asian American patients with HCC treated without transplantation has not been well studied. We reviewed our institution's experience to determine predictors and rates of survival in Asian American HCC patients treated without transplantation. Methods We identified Asian American patients with HCC referred to M. D. Anderson Cancer Center. Patients were tested for HBV and HCV. Survival curves were generated by Kaplan-Meier method. Multivariate Cox proportional hazards regression was used to test the relationship between prognostic factors and survival. Results Of 82 Asian American HCC patients, most had advanced disease (65% and received treatment (68%; however, only 11% had surgical resection. 94% had positive anti-HBc and 61% had positive HBsAg. 20% had positive anti-HCV. There were no significant changes in the rates of HBV and HCV over time. Male gender, high alpha-fetoprotein levels, and stage IV disease were associated with shorter survival Overall median survival was 9.2 months (95% CI 6.5–11.9, and the survival of HCV and HBV patients was not statistically different. Conclusion The survival rate of Asian American patients with advanced HCC, for whom transplantation was not available, was low. Timely hepatitis screening and interventions by primary care physicians may be the most logical solution to reduce the burden of hepatitis-associated HCC among Asian Americans.

  20. BRCC3 acts as a prognostic marker in nasopharyngeal carcinoma patients treated with radiotherapy and mediates radiation resistance in vitro

    International Nuclear Information System (INIS)

    BRCC3 has been found to be aberrantly expressed in breast tumors and involved in DNA damage response. The contribution of BRCC3 to nasopharyngeal carcinoma prognosis and radiosensitivity is still unclear. Immunohistochemical analysis of BRCC3 was carried out in 100 nasopharyngeal carcinoma tissues, and the protein level was correlated to patient survival. BRCC3 expression of nasopharyngeal carcinoma cell lines was determined by Western-blotting and real-time PCR. Additionally, the effects of BRCC3 knockdown on nasopharyngeal carcinoma cell clongenic survival, DNA damage repair, and cell cycle distribution after irradiation was assessed. The BRCC3 protein level was inversely correlated with nasopharyngeal carcinoma patient overall survival (P < 0.001) and 3-year loco-regional relapse-free survival (P = 0.034). Multivariate analysis demonstrated that BRCC3 expression was an independent prognostic factor (P = 0.010). The expression of BRCC3 was much higher in radioresistant nasopharyngeal carcinoma cells than in radiosensitive cells. Knockdown of BRCC3 increased the cell survival fraction, attenuated DNA damage repair and resulted in G2/M cell cycle arrest in radioresistant NPC cells. High BRCC3 expression in nasopharyngeal carcinoma patients is associated with poor survival. BRCC3 knockdown could abate the radioresistance in nasopharyngeal carcinoma cells. These findings suggest the utility of BRCC3 as a prognostic biomarker and novel target for nasopharyngeal carcinoma

  1. Combination of mTOR and MAPK Inhibitors—A Potential Way to Treat Renal Cell Carcinoma

    Full Text Available Renal cell carcinoma (RCC is the most common neoplasm that occurs in the kidney and is marked by a unique biology, with a long history of poor response to conventional cancer treatments. In the past few years, there have been significant advancements to understand the biology of RCC. This has led to the introduction of novel targeted therapies in the management of patients with metastatic disease. Patients treated with targeted therapies for RCC had shown positive impact on overall survival, however, no cure is possible and patients need to undergo treatment for long periods of time, which raises challenges to manage the associated adverse events. Moreover, many patients may not respond to it and even response may not last long enough in the responders. Many inhibitors of the Mammalian target of Rapamycin (mTOR signaling pathway are currently being used in treatment of advanced RCC. Studies showed that inhibitions of mTOR pathways induce Mitogen-Activated Protein Kinase (MAPK escape cell death and cells become resistant to mTOR inhibitors. Because of this, there is a need to inhibit both pathways with their inhibitors comparatively for a better outcome and treatment of patients with RCC.

  2. The clinical application of TACE together with RFA and 125I seed implantation in treating hepatocellular carcinoma

    International Nuclear Information System (INIS)

    Objective: to assess the clinical value of the combined treatment of transcatheter arterial chemoembolization (TACE), CT-guided radiofrequency ablation (RFA) and radioactive 125I seed implantation for hepatocellular carcinoma (HCC). Methods: During the period from March 2008 to Dec. 2010, 15 patients with HCC were admitted to the hospital. A total of 25 hepatic lesions were detected with the size of 1-8 cm. TACE was carried out first, which was followed by CT-guided RFA and radioactive 125I seed implantation. With the help of treat plan system (TPS), the radioactive 125I seed implantation was conducted to make additional management for the same lesion when RFA was finished, or the radioactive 125I seeds were directly implanted into the areas where RFA could not reach. The radioactive dose was 60-100 Gy. All the patients were followed up and were kept under observation for the signs of related complications. The therapeutic results were evaluated. Results: The combined treatment was successfully accomplished in all patients. All patients were followed up for 3-28 months (mean of 10.6 months). The complete necrosis rate of the tumor was 96%. No serious complications occurred except the immigration of 125I seeds in 1 case. Conclusion: The combined treatment of TACE and CT-guided RFA together with 125I seed implantation is a safe, reliable and effective therapy for HCC with excellent short-term result. (authors)

    This study was designed to analyze the clinical results in patients suitable for liver transplantation with hepatocellular carcinoma (HCC) who exceeded Milan criteria, which underwent intra-arterial therapies (IAT), to determine predictive factors of successful downstaging. A total of 277 consecutive patients with cirrhosis and HCC were treated by IAT (transarterial oily chemoembolization, transarterial chemoembolization, transarterial embolization) in a single center. Eighty patients exceed the Milan criteria. Patients with infiltrative HCC, hypovascular HCC, and portal vein thrombosis were excluded, with a final study population of 48 patients. Tumor response to IAT was evaluated with CT and/or MRI according to modified RECIST criteria. Successful downstaging was defined as a reduction in the number and size of viable tumors to within the Milan criteria, and serum alpha-fetoprotein (AFP) <100 ng/mL, for at least 6 months. Nineteen patients (39 %) had their tumors successfully downstaged; 29 patients (61 %) did not. Multivariate analysis showed that AFP level <100 ng/mL and 3-year calculated survival probability using the Metroticket calculator were the only independent predictors of successful downstaging (p < 0.023 and p < 0.049 respectively). Biological characteristics of HCC as AFP levels <100 ng/mL and high 3-year calculated survival probability may predict a good response to downstage after IAT.

    OBJECTIVE To evaluate the effect and safety of a Molecular Adsorbent Recycling System (MARS) in treating posthepatoectomy hepatic failure (AHF) patients surgically treated for primary hepatocellular carcinoma (HCC).METHODS 12 AHF patients induced by resection of HCC were treated with MARS before orthotopic liver transplantation (OLT). Their vital signs, urine volume, APACHE Ⅲ and Glasgow scores were monitored. Routine laboratory blood tests, measurements of coagulatory function, liver and kidney function, serum ammonia, lactic acid and blood gas were conducted before and after treatment with MARS. All of the patients were followed up for a period of 6 months after OLT for prognosis and complication assessment.RESULTS Each patient was treated with MARS for 2~5 times (average of 3.6) with a length of 8~24 h each time. Their mean arterial blood pressure and urine volume were improved, APACHE Ⅲ and Glasgow scores were better. Liver function was improved with the following alterations before and after treatment with MARS: serum ammonia (127.1±21.4 umol/L vs. 77.4±19.7 umol/L, P<0.05), lactic acid (6.53±0.45 mmol/L vs. 3.75± 0.40 mmol/L, P<0.05) and total bilirubin (452.3±153.7 umol/L vs. 230.9± 115.2 umol/L, P<0.05). However, there was no significant change in platelet count (44.25±3.60×109/L vs. 43.19±8.26×109/L, P>0.05) on international normalized ratio (INR) (2.74±0.50 vs. 2.82±0.60, P>0.05), which showed the safety of MARS. For all patients no serious adverse effects occurred during the treatment with MARS.CONCLUSION MARS is effective and safe for treatment of AHF patients with HCC, especially as a bridge to OLT when a donor organ is not available.

    Purpose: To report atypical clinical behavior observed in human papillomavirus (HPV)-related oropharyngeal carcinoma (OPC) treated with radiotherapy. Methods and Materials: A retrospective cohort study was conducted for all newly diagnosed OPC cases treated with radiotherapy on July 1, 2003 to April 30, 2009. HPV positivity was determined by p16 immunostaining in tumors. The incidence of additional malignancies and the pattern of distant metastases (DMs) were compared between the HPV-positive (HPV+) and HPV-negative (HPV-) cohorts. Results: HPV status was evaluated in 318 of 613 consecutive OPC cases (52%), showing 236 HPV+ and 82 HPV- patients. Compared with HPV-, HPV+ cases were less likely to have additional malignancies (prior: 11% vs. 20%, p = 0.038; synchronous: 1% vs. 9%, p = 0.001; metachronous: 6% vs. 16%, p = 0.003). Whereas the majority (10 of 12) of HPV- additional head-and-neck (HN) mucosal malignancies were in the oral cavity, there was none (0 of 7) in the HPV+ cohort (p < 0.001). HPV+ synchronous HN second primaries (SPs) were in the supraglottis, post-cricoid, and nasopharynx; metachronous HN SPs were in the glottis, supraglottis, and ethmoid plus glottis/post-cricoid region. All SPs that could be tested were HPV+. There was no difference in DM rate (10% vs. 15%, p = 0.272), but HPV+ DMs were more likely to involve multiple organs (46% vs. 0%, p = 0.005) and unusual sites. Conclusions: This study reports atypical clinical behavior seen in HPV+ OPC, including multicentric lesions in HN mucosa and DM to multiple organs and unusual sites. The frequency of these events is low, but they may have clinical implications. The routine assessment of HPV status for all OPC is warranted.

    Gelatin sponge particles are commonly used in the conventional transarterial chemoembolization (c-TACE) as an adjuvant embolizing agent for hepatocellular carcinoma (HCC). However, there are few reports regarding the clinical applications of gelatin sponge microparticles (GSMs) as a main embolizing agent in the treatment of HCC. This retrospective study aim to evaluate the efficacy and safety of patients with Barcelona Clinic Liver Cancer (BCLC) stage B HCC treated with intra-arterial injection of 350 to 560 μm GSMs mixed with anticancer agents.Twenty-four patients with unresectable BCLC stage B HCC without any prior treatment underwent transarterial chemoembolization with gelatin sponge microparticles (GSMs-TACE) of diameter 350 to 560 μm mixed with lobaplatin. The mixture was injected into tumor-feeding arteries until the sluggish flow in selective artery. Safety was measured by assessing complication rate, and efficacy was reflected by assessing response to mRECIST therapy and overall survival. The survival rate was calculated using the Kaplan-Meier method.All 24 BCLC stage B HCC patients showed good tolerance to the procedure. The mean follow-up period was 27 months and mean number of TACE treatments per patient was 3.7 sessions (range 1-10) during the follow-up period. Postprocedure complications were mild and treated by symptomatic treatment. Six months and 1 year overall survival rates were 100% and 87.5%, respectively. Overall median survival time was 25 months (95%CI: 21.06-28.95 months).GSMs-TACE is a safe and effective method for BCLC stage B HCC patients.

    Full Text Available To evaluate the predictive and prognostic value of pretreatment metabolic tumor volume (MTV in patients with treated by radiotherapy (RT or concurrent chemoradiotherapy (CCRT.We reviewed the records of 118 patients with newly diagnosed laryngeal carcinoma, who had been treated by RT or CCRT. Pretreatment positron emission tomography (PET was performed, and MTV values were obtained by contouring margins of standardized uptake value. Clinical factors and MTV were analyzed for their association with survival.Patients with residual disease showed a significantly higher MTV than those with a complete response (CR after primary treatment. Univariate analysis showed that the patients with a high MTV had a significantly lower disease-free survival (DFS (p < 0.001. Subsite (p = 0.010, T-stage (p < 0.001, nodal metastasis (p < 0.001 and clinical stage (p < 0.001 also correlated significantly with DFS. In the multivariate analysis, MTV and clinical stage were both found to be independent prognostic factors for DFS (p = 0.001, p = 0.034, respectively. The 3-year DFS for patients with a high MTV were significantly poorer than those with a low MTV (p < 0.001.MTV of the primary tumor is a significant prognostic factor for DFS in patients with laryngeal carcinoma treated by RT or CCRT. The results imply that MTV could be an important factor when planning treatment and follow-up for patients with laryngeal carcinoma.

    The aim of this study was to determine the prognostic value of wait time from histological diagnosis to primary treatmen for nasopharyngeal carcinoma (NPC) treated with intensity-modulated radiotherapy (IMRT). Between October 2009 and February 2012, a total of 1672 NPC patients were retrospectively analyzed. A cutoff value of > 4 weeks was used to define prolonged wait time. Matched patients according to the wait time were identified using propensity score matching (PSM), which was also used to identify matched patients for subsequent stratified analyses. Differences in progression-free survival (PFS), overall survival (OS), distant metastasis-free survival (DMFS), and locoregional relapse-free survival (LRFS) were estimated using the Kaplan-Meier method and Cox proportional hazards models. In total, 407 pairs of NPC patients were selected by PSM. The 3-year PFS rate was significantly lower for patients with a prolonged wait time (> 4 weeks) than for those with an acceptable wait time (P = 0.035). Stratified analyses revealed that the negative effects of a prolonged wait time occurred primarily in patients with advanced NPC without neoadjuvant chemotherapy (NACT; PFS:P = 0.040; DMFS:P = 0.028). In multivariate analysis, a prolonged wait time was found to be an independent unfavorable prognostic factor for PFS and DMFS in advanced-staged patients without NACT. These results suggest that a prolonged time (> 4 weeks) between diagnosis and primary radical radiotherapy is a disadvantage for NPC patients, particularly those with advanced disease receiving no NACT. Thus, it is necessary to optimize resources for decreasing this wait time, although additional studies are warranted to further clarify our findings. PMID:26942870

    Purpose: To extend the application of current radiation therapy (RT) based tumor control probability (TCP) models of nasopharyngeal carcinoma (NPC) to include the effects of hypoxia and chemoradiotherapy (CRT). Methods: A TCP model is described based on the linear-quadratic model modified to account for repopulation, chemotherapy, heterogeneity of dose to the tumor, and hypoxia. Sensitivity analysis was performed to determine which parameters exert the greatest influence on the uncertainty of modeled TCP. On the basis of the sensitivity analysis, the values of specific radiobiological parameters were set to nominal values reported in the literature for NPC or head and neck tumors. The remaining radiobiological parameters were determined by fitting TCP to clinical local control data from published randomized studies using both RT and CRT. Validation of the model was performed by comparison of estimated TCP and average overall local control rate (LCR) for 45 patients treated at the institution with conventional linear-accelerator-based or helical tomotherapy based intensity-modulated RT and neoadjuvant chemotherapy. Results: Sensitivity analysis demonstrates that the model is most sensitive to the radiosensitivity term {alpha} and the dose per fraction. The estimated values of {alpha} and OER from data fitting were 0.396 Gy{sup -1} and 1.417. The model estimate of TCP (average 90.9%, range 26.9%-99.2%) showed good correlation with the LCR (86.7%). Conclusions: The model implemented in this work provides clinicians with a useful tool to predict the success rate of treatment, optimize treatment plans, and compare the effects of multimodality therapy.

    Objective We sought to evaluate and compare the outcomes of different surgical protocols for papillary thyroid cancer (PTC) located in the isthmus in a retrospective intention-to-treat analysis. Patients and methods The data of 3,068 patients who received thyroidectomy due to thyroid cancer in our center were reviewed. Of these, 103 patients had a dominant carcinoma located in the isthmus. Various baseline and tumor characteristics and surgical outcomes were evaluated and compared with respect to the different surgical protocols (85 cases with total thyroidectomy and 18 cases with less-than-total thyroidectomy). Univariate and multivariate analyses were performed to identify resected patients who developed recurrence with isthmic PTC. Results The postoperative complication rates were comparable between the two groups (17.6% versus 11.1%, P=0.500). Although the total thyroidectomy group showed a much higher rate (P=0.004) and number (P0.05). Tumor recurrence was observed in five patients, including two patients in the total thyroidectomy group and three patients in the less-than-total thyroidectomy group; the tumor recurrence rate in the total thyroidectomy group was significantly lower than that in the less-than-total thyroidectomy group (P=0.040). Univariate and multivariate analyses indicated less-than-total thyroidectomy as a risk factor for tumor recurrence in PTC cases with tumors located at the isthmus (hazard ratio: 1.870, 95% confidence interval: 1.320–2.218, P<0.001). Conclusion Our findings indicate that total thyroidectomy is an appropriate initial surgical protocol for isthmic PTC due to the lower recurrence rate, comparable postoperative complication rate, and parathyroid function recovery.

    Introduction:Most hepatocellular carcinomas (HCC) develop in a background of underlying liver disease including chronic hepatitis B. However, the effect of antiviral therapy on the long-term outcome of patients with hepatitis B virus (HBV)-related HCC treated with chemoembolization is unclear. This study aimed to evaluate the survival benefits of anti-HBV therapy after chemoembolization for patients with HBV-related HCC. Methods:A total of 224 HCC patients who successfully underwent chemoembolization were identified, and their survival and other relevant clinical data were reviewed. Kaplan-Meier and Cox regression analyses were performed to validate possible effects of antiviral treatment on overall survival (OS). Results:The median survival time (MST) was 15.9 (95% confidence interval [CI], 9.5–27.7) months in the antiviral group and 9.6 (95% CI, 7.8–13.7) months in the non-antiviral group (log-rank test, P=0.044). Cox multivariate analysis revealed that antiviral treatment was a prognostic factor for OS (P=0.008). Additionally, a further analysis was based on the stratification of the TNM tumor stages. In the subgroup of early stages, MST was significantly longer in the antiviral-treatment group than in the non-antiviral group (61.8 months [95% CI, 34.8 months to beyond the follow-up period] versus 26.2 [95% CI, 14.5–37.7] months, P=0.012). Multivariate analysis identified antiviral treatment as a prognostic factor for OS in the early-stage subgroup (P=0.006). However, in the subgroup of advanced stages, MST of the antiviral-treated group was comparable to that of the non-antiviral group (8.4 [95%CI, 5.2–13.5] months versus 7.4 [95%CI, 5.9–9.3] months, P=0.219). Multivariate analysis did not indicate that antiviral treatment was a significant prognostic factor in this subgroup. Conclusion:Antiviral treatment is associated with prolonged OS time after chemoembolization for HCC, especially in patients with early-stage tumors.

    Purpose: Reports of intensity-modulated radiotherapy (IMRT) for early-stage nasopharyngeal carcinoma (NPC) have been limited. The present study evaluated the long-term survival outcomes and toxicity of early-stage NPC patients treated with IMRT alone. Methods and Materials: Between February 2001 and January 2008, 198 early-stage (T1-T2bN0-N1M0) NPC patients had undergone IMRT alone. The data from these patients were retrospectively analyzed. The patients were treated to 68 Gy at 2.27 Gy/fraction prescribed to the planning target volume of the primary nasopharygeal gross tumor volume. The Radiation Therapy Oncology Group scoring system was used to assess the toxicity. Results: At a median follow-up of 50.9 months (range, 12-104), the 5-year estimated disease-specific survival, local recurrence-free survival, and distant metastasis-free survival rate was 97.3%, 97.7%, and 97.8%, respectively. The 5-year local recurrence-free survival rate was 100% for those with Stage T1 and T2a and 94.2% for those with Stage T2b lesions (p = 0.252). The 5-year distant metastasis-free survival rate for Stage T1N0, T2N0, T1N1, and T2N1 patients was 100%, 98.8%, 100%, and 93.8%, respectively (p = .073). All local recurrence occurred in patients with T2b lesions. Five patients developed distant metastasis. Of these 5 patients, 4 had had Stage T2bN1 disease and 1 had had Stage T2bN0 disease with retropharyngeal lymph node involvement. The most common acute toxicities were mainly Grade 1 or 2. At 24 months after IMRT, no Grade 3 or 4 xerostomia had developed, and 62 (96.9%) of 64 evaluated patients were free of trismus; only 2 patients (3.1%) had Grade 1 trismus. Radiation encephalopathy and cranial nerve injury were not observed. Conclusions: IMRT alone for Stage T1N0, T2N0, T1N1, and T2N1 yielded satisfactory survival outcomes with acceptable toxicity, and no differences were found in survival outcomes among these four subgroups. Patients with Stage T2b lesions might have relatively

  15. Development and validation of a nomogram for prediction of survival and local control in laryngeal carcinoma patients treated with radiotherapy alone: A cohort study based on 994 patients

    International Nuclear Information System (INIS)

    Introduction: To advise laryngeal carcinoma patients on the most appropriate form of treatment, a tool to predict survival and local control is needed. Materials and methods: We performed a population-based cohort study on 994 laryngeal carcinoma patients, treated with RT from 1977 until 2008. Two nomograms were developed and validated. Performance of the models is expressed as the Area Under the Curve (AUC). Results: Unfavorable prognostic factors for overall survival were low hemoglobin level, male sex, high T-status, nodal involvement, older age, lower EQD2T (total radiation dose corrected for fraction dose and overall treatment time), and non-glottic tumor. All factors except tumor location were prognostic for local control. The AUCs were 0.73 for overall survival and 0.67 for local control. External validation of the survival model yielded AUCs of 0.68, 0.74, 0.76 and 0.71 for the Leuven (n = 109), the VU Amsterdam (n = 178), the Manchester (n = 403) and the NKI cohort (n = 205), respectively, while the validation procedure for the local control model resulted in AUCs of 0.70, 0.71, 0.72 and 0.62. The resulting nomograms were made available on the website (www.predictcancer.org). Conclusions: For patients with a laryngeal carcinoma treated with RT alone, we have developed visual, easy-to-use nomograms for the prediction of overall survival and primary local control. These models have been successfully validated in four external centers.

    To observe the effect of Shenlong Oral Liquid(SLOL)combined with radiotherapy in treating nasopharyngeal carcinoma (NPC). Methods: Effects of the combined therapy, including clinical effects, changes of cellular immunity and side effects, in treating 60 NPC patients (in the treated group) were observed and compared with those of the other 60 patients treated with radiotherapy alone (in the control group). Results: (1)The side effects of radiation in the treated group were lower than those in the control group significantly (P<0.05). (2) The short-term remission rate of nasopharyngeal and neck metastatic tumor in the two groups was not significantly different (P>0.05). (3) The dose for complete remission of nasopharyngeal and neck tumor in the treated group was lower than that in the control group (P<0.01). (4) No change of T-lymphocyte subsets was found in the treated group after treatment, but in the control group , OKT3,OKT4,and OKT4/OKT8 ratio were markedly decreased (P<0.05). (5) The survival rate in the treated group was higher than that in the control group, but with no statistical significance (P=0.0518). Conclusion: The combined therapy of NPC with SLOL and radiotherapy is able to reduce side-effect of radiotherapy, improve the cellular immunity, reduce the dose of radiation for tumor remission and enhance the therapeutic effect of radiotherapy. It showed a trend of raising the long-term survival rate of NPC patients.

    Background:Recently, studies have shown that plasma D‑dimer and serum albumin are prognostic markers for esophageal cancer. The purpose of this study was to evaluate a novel prognostic scoring system—DA score (combi‑nation of preoperative plasma D‑dimer and serum albumin levels)—and analyze the association between survival of patients with esophageal squamous cell carcinoma (ESCC) and their Glasgow prognostic score. Methods:In this retrospective study, preoperative biochemical markers and clinicopathologic factors in 260 ESCC patients treated with transthoracic esophagectomy were reviewed. According to receiver operating characteristic analysis, the cutoff values of D‑dimer and albumin were deifned as 0.5μg/mL and 43.8g/L, respectively. Patients with high D‑dimer levels (≥0.5μg/mL) and low albumin levels (<43.8g/L) were assigned a score of 2, those with only one of the two abnormalities were assigned a score of 1, and those with neither of the two abnormalities were assigned a score of 0. Results:ESCC patients with a DA score of 0, 1, and 2 numbered 55, 116, and 89, respectively. Survival analysis showed that patients with a DA score of 2 had lower overall survival (OS) rates than those with DA scores of 1 and 0 (37.1% vs. 52.6% and 76.4%,P<0.001); similar ifndings were observed for disease‑free survival (DFS) rates (32.6% vs. 44.8% and 67.3%,P<0.001). In addition, the predictive value of the DA score was also signiifcant in patients with stages I–IIA and stages IIB–IV ESCC. Multivariate Cox regression analyses indicated that hazard ratios (HRs) for predicting OS of patients with DA scores 1 and 2 were 2.25 (P=0.010) and 3.14 (P<0.001), respectively, compared with those with a DA score of 0, and HRs for predicting DFS of patients with DA scores of 1 and 2 were 1.86 (P=0.023) and 2.68 (P<0.001), respectively, compared with those with a DA scores of 0. Conclusions:Our study suggests that preoperative DA scores are notably associated with

    AIM: To study the influence of chemotherapy on proliferationactivation of tumor cell by observing the change ofchemiluminescence (CL) and cell cycle in various tumor celllines after mitomycin C treated.METHODS: BGC823 and LoVocell lines were all cultured inRPMI-1640, and then were adjusted to a concentration of1x105 cells/ml in fresh media.and incubated for 24 h.Mitomycin C (100 ng@ml-1) was added to each bottle. Allindeses were examined after 24 h. No Mitomycin C wasadded in control group. Each group contained 8 samples.Flow cytometric analysis and luminol-dependent CL wereused to investigate the effect of mitomycin C on twogastrointestinal carcinoma cell lines.RESULTS: BGC823 and LoVo cell lines incubated with MMCfor 24 h. We discovered that the emergence of peak of CLstimulated by PHA was postponed significantly (BGC823:12.63±3.21 vs 4.50±1.04, LoVo: 13.25+2.96 vs 5.12±1.36,P<0.01) and the peak intension of CL was reduced significantly(BGC823:120.25±16.61 vs248.38±29.17, LoVo: 98.13±10.49vs267.50±18.56, P<0.01).The PI of cell lines was decreasedsignificantly (BGC823:51.87±4.82 vs 25.44±2.26, LoVo:47.11±1.04 vs 24.23±0.37, P<0.01) and the apoptoticfractions changed by contraries (BGC823:26.25+5.29 vs9.83±2.51, LoVo: 33.50±3.68 vs9.63±1.44, P<0.01).CONCLUSION: CL can be used to measure activation oftumor cells. We discovered that the ground CL intensions oftwo cell lines were not high but increased rapidly afterstimulation of PHA. The CL peak ranged from 4-5 minutes,and then decreased gradually. The results were not reportedbefore. CL of tumor cell has close correlativity with thedynamics of cell cycle and can reflect the feature of oxidationmetabolism and proliferation activation of tumor cell. So itcan be used to observe the influence of chemotherapydrug on metabolism and proliferation activation of tumorcell and screen out chemotherapy drugs to which tumorcells are sensitive.

    1995-03-01

    We have used ultra-low light level fluorescence microscopy to examine the suggestion that the relatively poor response of human basal cell carcinomas (BCC) to topical 5-aminolaevulinic acid (ALA)-based photodynamic therapy (PDT) arises from limited drug penetration into the lesion. The distribution of ALA-induced protoporphyrin IX (PpIX) in human BCC and Bowen's disease was examined and, in almost all cases, was found to be most intense in those regions of tumor immediately adjacent to the dermis. This distribution was independent of tumor type, and did not appear to be affected by tumor depth in the skin. It is suggested that ALA penetration may not limit the efficacy of ALA-PDT in the treatment of BCC. Failure of superficial ALA-based PDT in basal cell carcinoma may, instead, be related to the histological structure of this type of lesion.

  2. A case of thyroid medullary carcinoma with multiple painful bone metastases successfully treated with strontium-89 chloride

    International Nuclear Information System (INIS)

    A 70-year-old man was diagnosed as thyroid medullary carcinoma with multiple bone metastases. He underwent total thyroidectomy and cervical lymph node dissection. After one year, the pain from his bone lesions was becoming severe. To relieve the pain, he was administered opioids and external-beam radiation therapy. However, he continued to have substantial multiple bone pain. We used combination therapy of strontium-89 chloride for the treatment of widespread multiple bone pain and external-beam radiation therapy for localized pain. That combination therapy was effective and improved the quality of life (QOL) of the patient. We used strontium-89 chloride four times within one year, and no serious side effects occurred during therapy. Our thoroughly investigated case suggests that strontium-89 therapy is one of the effective and safe therapies for patients with painful bone metastases of thyroid medullary carcinoma. (author)

    Sunitinib is a standard first-line option for metastatic renal cell carcinoma (mRCC). Body composition is a prognostic factor in cancer patients and patients with loss of skeletal muscle mass and fat-free mass (FFM) are prone to dose-limiting toxicity (DLT) during targeted drug therapy. We investigated whether body composition by computed tomography predicted DLT from sunitinib in mRCC.

  4. High expression of KPNA2 defines poor prognosis in patients with upper tract urothelial carcinoma treated with radical nephroureterectomy

    International Nuclear Information System (INIS)

    To analyze the expression of karyopherin alpha 2 (KPNA2) in upper tract urothelial carcinoma (UTUC) and to investigate whether the KPNA2 expression provides additional prognostic information following radical nephroureterectomy (RNU). A tissue microarray (TMA) containing samples from 176 patients with UTUC who underwent RNU at our institute was analyzed for KPNA2 expression using immunohistochemistry. KPNA2 expression in normal urothelial cell line and urothelial carcinoma cell lines was evaluated by western blot analysis. Using RNA interference in vitro, the effects of KPNA2 inhibition on cellular viability, migration and apoptosis were determined. KPNA2 expression was significantly upregulated in the UTUC samples compared with the adjacent normal urothelial tissues. High KPNA2 immunoreactivity was identified as a predictor of bladder recurrence (hazard ratio [HR]: 2.017, 95% CI 1.13-3.61, p = 0.018), poor disease-free survival (DFS, HR: 2.754, 95% CI 1.68-4.51, p = 0.001) and poor overall survival (OS, HR: 4.480, 95% CI 1.84-10.89, p = 0.001) for patients with UTUC after RNU. Furthermore, high KPNA2 immunoreactivity was independent of the conventional predictive factors in a multivariate analysis. Additional in vitro experiments revealed that KPNA2 expression was higher in urothelial carcinoma cell lines than in normal urothelial cell line. KPNA2 inhibition with a specific siRNA decreased cell viability and migration and increased apoptosis in urothelial carcinoma cell lines. KPNA2 is a novel independent prognostic marker for bladder recurrence, DFS and OS of UTUC patients who have undergone RNU. Moreover, these data suggest that KPNA2 may be a promising therapeutic target for UTUC

    Purpose: To assess the outcomes, toxicity, and quality of life (QOL) of patients with primary parotid carcinoma treated with surgery and postoperative radiotherapy at the Daniel den Hoed Cancer Center. Methods and Materials: Between 1995 and 2010, 186 patients with parotid carcinoma were treated with parotidectomy with or without neck dissection, followed by radiotherapy. Elective nodal irradiation (ENI) was applied to high-risk, node-negative disease. End points were locoregional control (LRC), disease-free survival (DFS), cause-specific survival (CSS), and overall survival (OS), late toxicity, and QOL. Results: After a median follow-up of 58 months (range, 4-172 months), the 5-year Kaplan-Meier estimates for LRC, DFS, CSS, and OS were 89%, 83%, 80%, and 68%, respectively. Forty-five events were reported: 24 distant metastases (DM) and 21 locoregional failures (LRF). Event-free survival rates by histological types were 89%, 78%, 76%, 74%, and 70% for acinic cell, mucoepidermoid, adenoid cystic, adenocarcinoma, and squamous cell carcinoma, respectively. More LRF were reported in patients with squamous cell and high-grade mucoepidermoid carcinoma (21% and 19%, respectively) than in patients with other histological types (p = 0.04) and more DM in patients with adenoid cystic and adenocarcinoma (20% and 19%, respectively) than in patients with other types (p = 0.03). None of the high-risk node-negative patients who received ENI developed regional failure. On multivariate analysis, T stage, N stage, grade, and presence of perineural invasion and facial paralysis correlated significantly with DFS. The 5-year cumulative incidence of grade {>=}2 late toxicity was 8%. QOL scores deteriorate during and shortly after treatment but returned in almost all scales to baseline scores within 6 months. Conclusions: Of the entire group, surgery and postoperative radiotherapy resulted in excellent outcomes with minimal side effects and preservation of good QOL scores. However, in

    BACKGROUND: Radiation encephalopathy (RE) caused by radiation therapy of nasopharyngeal carcinoma severely influences patients' quality of life (QOL). The factors, which influence such patients' QOL, have not been confirmed.OBJECTIVE: To observe the clinical and imageological characteristics of patients with radiation therapy of nasopharyngeal carcinoma-induced RE and the changes in QOL, and analyze QOL influencing factors.DESIGN: Retrospective case analysis.SETTING: Department of Neurology, the Second Affiliated Hospital of Sun Yat-sen University.PARTICIPANTS: Eighty-nine inpatients or outpatients with RE induced by radiation therapy of nasopharyngeal carcinoma admitted to Sun Yat-sen University Cancer Center and Department of Neurology,the Second Affiliated Hospital of Sun Yat-sen University from March 1994 to August 2004 were involved in this experiment. They all met the diagnosis criteria of RE from MERRITT'S neurology (10th edition).Thirty-three involved patients were randomly chosen as RE group. Another 34 concurrent inpatients or outpatients with nasopharyngeal carcinoma who received radiation therapy but without RE were chosen as control group. Informed consents of detected items were obtained from all the involved subjects.Quality of Life Questionnaire abbreviated version (WHOQOL-BREF) was used for on-the-spot evaluation.High points of WHOQOL-BREF indicated better QOL. The Late Effects on Normal Tissues - Subjective,Objective, Management and Analytic (LENT-SOMA) scale for evaluating radiation injury was used to evaluate headache and neurologic disorder of patients with RE induced by radiation therapy of nasopharyngeal carcinoma. The evaluation was graded into 5 degrees. High degrees indicted severer clinical therapy ending to onset), initial symptoms, common symptoms, imageological characteristics, QOL and other software.MAIN OUTCOME MEASURES: QOL and clinical characteristics of patients with RE induced by radiation therapy of nasopharyngeal carcinoma as

    Full Text Available Abstract Objective To explore the role of Major Vault Protein (MVP in oral cavity squamous cell carcinoma patients. Subjects and Methods 131 consecutive patients suffering from oral cavity squamous cell carcinoma were included in the study. In the whole series, the mean follow-up for survivors was 123.11 ± 40.36 months. Patients in tumour stages I and II were referred to surgery; patients in stage III-IV to postoperative radiotherapy (mean dose = 62.13 ± 7.74 Gy in 1.8–2 Gy/fraction. MVP expression was studied by immunohistochemistry in paraffin-embedded tumour tissue. Results MVP expression was positive in 112 patients (85.5% and no relation was found with clinic pathological variables. MVP overexpression (those tumours with moderate or strong expression of the protein was related to insulin-like growth factor receptor-1 (IGF-1R expression (P = 0.014. Tumour stage of the disease was the most important prognostic factor related to survival. Tumours overexpressing MVP and IGF-1R were strongly related to poor disease-free survival (P = 0.008, Exp(B = 2.730, CI95% (1.302-5.724 and cause-specific survival (P = 0.014, Exp(B = 2.570, CI95% (1.215-5.437 in patients achieving tumour stages III-IV, in multivariate analysis. Conclusions MVP and IGF-1R expression were related in oral squamous cell carcinoma and conferred reduced long-term survival in patients suffering from advanced stages of the disease.

    Purpose: To investigate the clinical features, prognostic factors, and toxicity of treatment for unresectable carcinomas of the nasal cavity and paranasal sinus (NCPS) treated with proton beam therapy (PBT). Methods and Materials: Seventeen patients (13 men, 4 women) with unresectable carcinomas of the NCPS who underwent PBT at University of Tsukuba between 2001 and 2007 were analyzed. The patients' median age was 62 years (range, 30-83 years). The tumors were located in the nasal cavity in 3 patients, the frontal sinus in 1, the ethmoid sinus in 9, and the maxillary sinus in 4. The clinical stage was Stage IVA in 5 cases, IVB in 10, and recurrent in 2. The tumors were deemed unresectable for medical reasons in 16 patients and because of refusal at a previous hospital 4 months earlier in 1 patient. All the patients received PBT irradiation dose of 22-82.5 GyE and a total of 72.4-89.6 GyE over 30-64 fractions (median 78 GyE over 36 fractions) with X-ray, with attention not exceeding the delivery of 50 GyE to the optic chiasm and brainstem. Results: The overall survival rate was 47.1% at 2 years and 15.7% at 5 years, and the local control rate was 35.0% at 2 years and 17.5% at 5 years. Invasion of the frontal or sphenoid sinus was a prognostic factor for overall survival or local control. Late toxicity of more than Grade 3 was found in 2 patients (brain necrosis in 1 and ipsilateral blindness in 1); however, no mortal adverse effects were observed. Conclusion: Proton beam therapy enabled a reduced irradiation dose to the optic chiasm and brainstem, enabling the safe treatment of unresectable carcinomas in the NCPS. Superior or posterior extension of the tumor influenced patient outcome.

  10. Comparative adequacy of surgery and radiation therapy in 175 T2 glottic carcinomas: 116 cases treated with surgery and 59 with radiation therapy

    International Nuclear Information System (INIS)

    The results were analyzed of 175 patients with glottic squamous cell carcinomas who were treated with curative purposes (1970-1986). Overall 10-year local control rates were 74% for the surgical series and 69% for the cases treated by radiation therapy. After salvage therapy 10-year survival rates were 83% and 76% respectively. The analysis of the results showed no statistically significant difference. In the group treated by radical surgery 80% local control was observed, versus 66% in the cases treated with conservative surgery. 10-year survival rate was higher in the latter group (89% versus 81%) because of better results of salvage therapy: 7 of 10 recurrences were salvaged with the second treatment. Several prognostic factors were evaluated-i.e., T extent, anterior commissure involvement, subglottic invasion, vocal cord mobility impairment, and ventricular involvement. Anterior commissure involvement was the main factor affecting out-come in the surgical series: in the presence of this factor, 64% 10-year local control was observed versus 85% in the patients without commissure involvement. This factor proved more important in the patients treated with conservative surgery (10-year control: 42 versus 88%) than in those undergoing radical surgery (78% versus 85%). Anterior commissure involvement and the number of involved subsites were found to worsen prognosis in the serial treated by radiation therapy: cases with anterior commissure involvement had 59% 10-year local control versus 83%. The cases with a deeper spread had 60% local control versus 75%. Vocal cord mobility impairment was a less important prognosis factor in both series. Our results suggest radiation therapy as a valuable method in a treatment of the small T2 laryngeal cancers which are not suitable for conservative surgery

    Full Text Available OBJECTIVE: To analyze the results of the treatment of transitional cell carcinoma (TCC of the bladder with radical cystectomy and determine which prognostic factors can be utilized as disease-free survival and cancer-specific survival independent variables. MATERIALS AND METHODS: Medical records of 113 patients submitted to radical cystectomy and bilateral iliac lymphadenectomy between 1993 and 2005 were reviewed. The risk factors analyzed were age, sex, pathological stage, tumor grade, presence of carcinoma in situ and the presence of lymph nodes involvement. RESULTS: After a mean follow-up of 31.7 ? 28.5 months, 46 patients (40.7% presented recurrence and 24 patients (21.2% died due to cancer. Only pathological stage and the lymph nodes involvement became independent variables for recurrence and survival. Patients with T4 stage presented 9.6 times the risk of recurrence of the disease when compared with stage T0 patients (p = 0.010 and the patients with lymph node involvement presented 2.5 times the risk of recurrence (p = 0.047 and 3.1 times the risk of death (p = 0.022 when compared to patients without lymph nodes involvement. CONCLUSIONS: Pathological stage and the involvement of lymph nodes represented more important prognostic variables, and in the presence of advanced stage tumors (T3/T4 and involvement of lymph nodes, the institution of adjuvant treatment should be considered.

    The administration of I-131 to patient with Differentiated Thyroid Carcinoma (CaDiT) it is used inside the therapeutic outline as later step to the thyroidectomy. However, the good activity to give is of difficult determination due to factors such as, the variability in the capacity of tumoral reception of the I-131, distribution of the pharmaceutical, physiologic status, other associate pathologies, grade of advance of the illness, and previous treatments. Additionally, the activity to administer is dependent of the dose of tolerance in the healthy tissues; superior dose to 2 Gy in bone marrow, its could drive to myelotoxicity. At the moment, the form more extended of administration it is the empiric prescription that considers clinical parameters and of laboratory for their determination. Presently work, the protocol of applied treatment incorporates the evaluation for internal dosimetry and biological dosimetry to estimate absorbed dose in bone marrow. The biological estimate of the dose of these patients is based on the quantification of chromosomal aberrations whose frequency is referred to a curve-dose response in which the lymphocytes is irradiated in vitro with I-131, allowing to determine the in vivo dose to the patient's circulating lymphocytes. The objective of the present work is to determine the applicability of different cytogenetic essays in the estimate of the absorbed dose to the whole body or specific organs. Three patients were evaluated with CaDiT. Their treatment protocol consisted on a tracer administration of radioactive iodine of 74 - 111 MBq (2 - 3 mCi) and a therapy 7,4 - 11,1 GBq (200 - 300 mCi). Previous to the tracer administration and 8 days post-therapeutic administration took samples of veined blood that were evaluated by biological dosimetry by means of the application of the techniques: conventional cytogenetic Micronucleus and FISH (Hybridization in situ by Fluorescence). Starting from the frequencies of observed chromosomal

    AIM: To compare the effect of transarterial chemoembolization (TACE) plus GRGDSP (Gly-Arg-Gly-Asp-Ser-Pro, integrin-inhibitor) loaded nanoparticles with TACE alone or TACE + GRGDSP in a rat model of liver tumor. METHODS: Morris hepatoma 3924A tumors were implanted in the livers of 30 ACI rats. The ACI rats were divided randomly into three groups (10 animals each). Tumor volume before treatment (V1) was examined by magnetic resonance imaging (MRI), and then, after laparotomy and placement of a PE-10 catheter into the hepatic artery, the following interventional protocols were performed: TACE (mitomycin C + lipiodol + degradable starch microspheres) + GRGDSP loaded nanoparticles for group A; TACE + GRGDSP for group B (control group 1); TACE alone for group C (control group 2). Tumor volume (V2) was assessed by MRI and the mean ratio of the post-treatment to pretreatment tumor volumes (V2/V1) was calculated. Immunohistochemical analysis was performed to assess the quantification of matrix metalloprotein 9 (MMP-9) and vascular endothelial growth factor (VEGF) positive tumor cells in each treatment group. RESULTS: The mean tumor growth ratios (V2/V1) were 1.3649 ± 0.1194 in group A, 2.0770 ± 0.1595 in group B, and 3.2148 ± 0.1075 in group C. Compared with groups B and C, group A showed a significant reduction in tumor volume. Lower expression of MMP-9 and VEGF in hepatocellular carcinoma was observed in group A than in groups B and C. The angiogenesis of tumor was evaluated using anti-VEGF antibodies, and the metastasis of tumor was assessed using anti-MMP-9 antibody. MMP-9 and VEGF were expressed in all specimens. The immunoexpression of these proteins was confirmed by the presence of red cytoplasmic staining in tumor cells. Lower expression of MMP-9 and VEGF in hepatocellular carcinoma was observed in group A than in groups B and C. CONCLUSION: Transarterial administration of integrin inhibitor loaded nanoparticles combined with TACE evidently retards tumor growth

    Full Text Available INTRODUCTION: To evaluate the prognostic value of gross tumor volume (TV in patients with locally recurrent, nonmetastatic nasopharyngeal carcinoma. METHODS: Between 2001 and 2012, 291 consecutive patients with locally recurrent, nonmetastatic nasopharyngeal carcinoma underwent salvage IMRT were retrospectively reviewed. The correlations between TV and recurrent T classification were analyzed. Survival analyses were performed. Receiver operating characteristic (ROC curves were calculated to identify cut-off point of TV. The Akaike information criterion and Harrell's concordance index (c-index were utilized to test the prognostic value. RESULTS: The median TV significantly increased with advancing recurrent T classification (P<0.001. The 5-year overall survival rate was 33.2% for the entire cohort. On multivariate analysis, TV was an independent negative prognostic factor for distant metastasis-free survival (hazard ratio =1.013, P =0.003, overall survival (hazard ratio = 1.015, P<0.001 and toxicity-related death (hazard ratio = 1.014, P<0.001. The 5-year overall survival rates were 63.1% and 20.8% for patients with a TV < 22 cm3 and TV ≥22 cm3, respectively (P < 0.001. In patient with TV <22 cm3, locoregional failure is the leading cause of death. In patients with TV≥22 cm3, distant metastasis rate is higher and occurred within short term after local recurrence; meanwhile, radiation-induced injuries became more common and led to half of deaths in this group. The Akaike information criterion and c-index analyses indicated that the predictive ability of recurrent T classification improved when combined with TV. CONCLUSIONS: Our data suggests TV is a significant prognostic factor for predicting the distant metastasis, overall survival and toxicity-related death of patients with locally recurrent, nonmetastatic nasopharyngeal carcinoma after salvage IMRT. TV should be considered when designing personalized salvage treatments for these patients

    We report the case of a 63-year-old woman with adenoid cystic carcinoma of the lower trachea treated by resection of 11 of the 18 cartilaginous rings (61%) of the total length. The little remaining membranous portion of the carina was sewn up to create a margin for anastomosis. The anastomotic sites could be approximated by the mobilization of the cervical trachea and the left main bronchus, pulling across the traction sutures, and anteflexion of the neck. The patient's postoperative course was uneventful without any complications associated with anastomosis. Because both the proximal and distal margins showed microscopic tumors, radiation therapy was performed with 50 Gy 2 months after surgery. The patient has a good social life without recurrence 20 months after surgery. PMID:25261213

    The purpose of this study was to retrospectively assess the incidence of bowel wall oedema on computed tomography (CT) in patients with renal cell carcinoma (RCC) treated with sunitinib, and to investigate its association with diarrhoea. We conducted a retrospective analysis of all RCC patients treated with sunitinib at our hospital between December 2005 and December 2011. The presence or absence of bowel wall oedema on these CT examinations was scored. The presence of diarrhoea preceding, during, or after sunitinib treatment was identified from the patient files and retrospectively graded. For 54 of 87 patients, bowel wall oedema was present on at least one CT examination. Of these 54 patients, the right-sided colonic segment was affected in 87 %. Diarrhoea was the most common reported adverse event during treatment, with 58 patients (67 %) having grade 1/2 diarrhoea and 9 patients (10 %) having grade 3. There was a statistically significant correlation between the incidence of CT-scored bowel oedema and diarrhoea during sunitinib treatment (P = 0.004). This study shows a very high incidence of bowel wall oedema and a strong correlation between the incidence of bowel wall oedema and diarrhoea in patients treated with sunitinib. (orig.)

    Full Text Available This study aims to investigate the prognostic value of neutrophil to lymphocyte ratio (NLR in hepatocellular carcinoma (HCC patients treated with liver transplantation (LT through meta-analysis. Relevant articles were sought in PubMed, Embase, and Wangfang databases up to July 2015. A total of 1687 patients from 10 studies were included in this meta-analysis. Meta-analysis results showed that elevated NLR was significantly associated with poorer overall survival (OS (HR = 2.71, 95% CI: 1.91–3.83 and poorer disease-free survival (DFS (HR = 3.61, 95% CI: 2.23–5.84 in HCC patients treated with LT. Moreover, subgroup analysis showed the significant association between elevated preoperative NLR and poor prognosis was not altered by cutoff values of NLR or types of LT. Therefore, elevated preoperative NLR is associated with poor prognosis in HCC patients treated with LT. Preoperative NLR should be used to predict the prognosis of HCC after LT in our clinical work.

    Differentiated thyroid carcinoma (DTC) is generally indolent in nature and, even though it metastasizes to distant organs, the prognosis is normally excellent. In contrast, the overall survival (OS) of patients with radioactive iodine (RAI)-refractory and progressive metastases is dire, because no effective therapies have been available to control the metastatic lesions. However, recently, administration of tyrosine-kinase inhibitors (TKIs) has become a new line of therapy for RAI-refractory and progressive metastases. Previous studies have reported significant improvement regarding the progression-free survival rates of patients with metastatic lesions. However, TKIs cause various severe adverse events (AEs) that damage patients' quality of life and can even be life-threatening. Additionally, metastatic lesions may progress significantly after stopping TKI therapy. Therefore, it is difficult to determine who is a candidate for TKI therapy, as well as how and when physicians start and stop the therapy. The present review, created by Committee of pharmacological therapy for thyroid cancer of the Japanese Society of Thyroid Surgery (JSTS) and the Japan Association of Endocrine Surgeons (JAES) describes how to appropriately use TKIs by describing what we do and do not know about treatment using TKIs.

    Full Text Available Squamous cell carcinoma (SCC is the second most common type of skin cancer with potential risks for metastasis and recurrence if left untreated or incompletely excised. This case series study was designed to determine the frequency of incompletely excised SCCs and the related risk factors. A total of 273 SCCs (253 patients excised in Razi dermatology hospital of Tehran from 2006-2008, were evaluated and were analyzed by Chi-square or t-test. The incidence of incomplete excision was 17.58 % and deep margin involvement was observed in 73% of lesions. Risk factors associated with incomplete excision of SCCs were being female, location of the tumors (in particular the lesions on lateral canthus, upper lip, foot, forehead, cheek, neck, nose and ear, large lesions and grafting method of repair. There was no statistically significant difference for the age, degree of histological differentiation, childhood history of radiotherapy for tinea capitis and the type of anesthesia. More care should be taken for high risk SCCs as complete excision avoids potential risk of recurrence and metastasis.

    Background The benefit of combined chemoradiation in elderly patients with human papillomavirus (HPV)-positive locally advanced oropharyngeal squamous cell carcinoma (SCC) must be balanced with the potential for higher toxicity rates. We performed a retrospective review of our institutional experience. Methods Patients 70 years or older with p16-positive oropharyngeal SCC treated with definitive chemoradiation from 2005 to 2013 were evaluated. Overall survival (OS), disease-free survival (DFS), and locoregional failure–free survival were calculated. Results Twenty-one eligible patients had a follow-up of 22.4 months. Estimated 5-year OS, DFS, and locoregional failure–free survival were 76.0%, 40%, and 95%, respectively. There was 1 death from acute toxicity, and 50% had unplanned hospitalizations. Sixty percent had late toxicity, and 6-month feeding tube dependence was 25%. Conclusion Elderly patients with HPV-positive locally advanced SCC of the oropharynx treated with definitive chemoradiation had good OS but high rates of acute and long-term toxicity. PMID:25899391

    Treatment of anorectal Buschke-Löwenstein tumor (BLT) with squamous cell carcinoma (SCC) transformation is not univocal given the rarity of the disease. BLT is characterized by its large size and tendency to infiltrate into underlying tissues. Malignant transformation can occur and it is important to identify the presence of neoplastic foci to decide the proper treatment. Our aim was to assess the effectiveness of neo-adjuvant chemo-radiation therapy (CRT) and local excision in order to avoid abdomino-perineal resection (APR). Three cases of anorectal BLT with SCC transformation are presented. All patients were HIV positive and treated with antiretroviral drugs. They underwent preoperative endoanal ultrasound, biopsies, total body tomography and anal brushing. Treatment consisted of neo-adjuvant chemo-radiation therapy (45 Gy to the pelvis plus a boost with 14.40 Gy to the primary tumor for a total of 59.40 Gy, and mitomycin-C in bolus on the first day, plus 5-fluorouracil by continuous infusion in the first and in the sixth week) and subsequent local surgical excision. During the follow-up, patients were subjected to the same preoperative diagnostic investigations and high resolution anoscopy. All patients showed a complete regression of the lesion after CRT and were treated by local surgical excision, thus avoiding permanent colostomy. In conclusion neo-adjuvant chemo-radiation therapy with local surgical excision could be considered an effective therapy in the treatment of anorectal BLT with SCC transformation to avoid APR.

  7. The importance of immunohistochemical expression of EGFr in squamous cell carcinoma of the oral cavity treated with surgery and postoperative radiotherapy

    International Nuclear Information System (INIS)

    Purpose: The aim of this study was to investigate the prognostic significance of epidermal growth factor (EGFr) expression in oral cavity squamous cell carcinoma (OCSCC) treated with curative surgery and postoperative radiotherapy. Methods and Materials: This retrospective study included 165 OCSCC patients. The expression of EGFr was assessed on paraffin-embedded tissue of the primary tumor by immunohistochemistry using a monoclonal antibody directed against EGFr. Intensity of the EGFr expression was scored by two authors blinded for the clinical outcome. Results: In the univariate analysis, locoregional control at 3 years (LRC) in the EGFr-negative cases was 69% compared with 77% in the EGFr-positive cases (p 0.22). In the multivariate analysis for local control, a significant interaction was found between EGFr and overall treatment time of radiation (OTT). After stratification for EGFr expression, the OTT was of no importance in the EGFr-negative cases, whereas a significant difference in LRC was found in the EGFr-positive cases, in which the LRC after 3 years was 69% and 94% in case of an OTT of 0-42 days and >42 days, respectively (p = 0.009; hazard ratio = 3.42; 95% confidence interval, 1.28-8.96). No significant association was found between EGFr expression and overall survival. Conclusions: In the present study, no association was found between EGFr expression and outcome regarding locoregional control and overall survival. However, the results of the present study suggest that patients with squamous cell carcinoma of the oral cavity with high EGFr expression benefit more from a reduction of the overall treatment time of postoperative radiation than those with low EGFr expression

Out of the 550 cases, 214 completed radical radiotherapy (EBRT + HDR-ICRT and were retrospectively analyzed for presence of local residual disease, local recurrence, distant metastases, radiation reactions, and disease-free survival. Results: There were 7 (3.27%, 88 (41.1%, 101 (47.1%, and 18 (8.4% patients in stage I, II, III, and IV, respectively. The median follow-up time for all patients was 43 months (range: 3-93 months and for patients who were disease free till the last follow-up it was 59 months (range: 24-93 months. The overall treatment time (OTT ranged from 52 to 73 days (median 61 days. The 5-year disease-free mean survival rate was 58%, 44%, 33%, and 15%, with 95% confidence interval of 48 to 68, 37 to 51, 24 to 35, and 6 to 24 for stages I, II, III, and IV, respectively. There were 62 (28.97% cases with local residual disease, 35 (16.3% developed local recurrence/distant metastases, 17 (7.9% developed distant metastases, and 9 (4.2% had local recurrence as well. Discussion and Conclusion: The overall outcome was poor in advanced stage disease, but might be improved by increasing the total dose, decreasing overall duration of treatment, and by adding chemotherapy in patients with disease limited to the pelvis.

Patients and methods: A total of 327 patients with advanced renal cell carcinoma and mRCC who received targeted therapy in two Chinese clinical centers were analyzed retrospectively. The patients were stratified into three groups: young (aged <45 years, middle-aged (aged 45–64 years, and old (aged ≥65 years. Overall survival (OS and progression-free survival (PFS curves were drawn using the Kaplan–Meier method, and Cox's proportional hazard regression model was used to compare OS and PFS within age groups. Results: There were no significant differences among young, middle-aged, and old groups in terms of OS (P=0.087, whereas PFS in the old group was significantly better than in the young and middle-aged groups (P=0.043. Both OS and PFS in the younger groups (aged <65 years were significantly worse than in the old group (age ≥65 years; median OS, 28.1 vs 28.7 months [P=0.029]; median PFS, 11.4 vs 14 months [P=0.015]. No difference in OS or PFS was found between the young and middle-aged groups. After adjusting for sex, body mass index, smoking status, hypertension, diabetes mellitus, Eastern Cooperative Oncology Group score, history of cytokines, and Fuhrman grade, old age was an independent favorable prognostic factor for OS and PFS compared with younger age (<65 years (OS, hazard ratio, 0.552 [95

    Purpose: Given the paucity of data on racial disparities in ductal carcinoma in situ (DCIS), the data from a multi-institutional cohort of DCIS patients treated with breast-conserving surgery and whole breast radiation therapy (RT) were analyzed to determine whether racial disparities or differences exist. Methods and Materials: A total of 533 white and 76 black DCIS patients from 3 university-based cancer centers were uniformly treated with breast-conserving surgery and RT. All patient data were collected and analyzed as a function of race. Results: The median follow-up was 5.2 years. No significant racial differences were seen in tumor size, age at diagnosis, estrogen receptor status, necrosis, or grade (all P>.05). Of the treatment parameters, the RT dose delivered, boost, positive margin rates, frequency of hormone receptor status assessment, and receipt of hormonal therapy for the 2 cohorts did not significantly differ (all P>.05). The local relapse-free survival was similar at 5 years (96.1% and 98.1%, P=.399) and 10 years (92.8% vs 95.8%, P=.360), with no significant overall survival difference at 10 years (94.0% vs 88.9%, P=.290) between the white and black patients, respectively. On multivariate analysis, race was not an independent predictor of local relapse-free survival or overall survival when accounting for age, grade, and margin status. Conclusion: In our large cohort of DCIS patients uniformly treated at 3 institutions with breast conservation without any apparent differences in treatment delivery parameters, we demonstrated that the clinical and pathologic features and local survival outcomes did not differ as a function of race. Our results suggest that when black patients with DCIS are appropriately selected for breast conservation and receive adjuvant RT without racial disparities in the treatment parameters, differences in the outcomes as a function of race do not exist.

  12. Stage I-II carcinoma of the anterior two-thirds of the tongue treated with different modalities

    International Nuclear Information System (INIS)

    Treatment results of 244 patients with stage I-II cancer of the mobile tongue were analyzed according to the modalities employed (implantation, surgery, cryosurgery and intraoral irradiation). Overall local control rates at 3 years were 90+-3 percent for implant, 89+-7 percent for cryosurgery, and 84+-9 percent for surgery. Local control rates in stage II patients treated with intraoral electron irradiation, however, were only 50+-13 percent. Five-year survival rates were 72+-3 percent with no significant differences observed in patients with either stage I or stage II regardless of treatment modality. Sixty percent (29/48) of the patients with local recurrences were salvaged by the 2nd treatment. Since the local control and survival achieved by these modalities were similar, with the exception of patients with stage II treated by intraoral electron irradiation, authors recommend inter-stitial implantation with iridium, intraoral electron irradiation or surgery for patients with T1 tumors, and iridium implantation or surgery for patients with T2 tumors. For those with superficial lesions measuring 5 mm or less in thickness, cryosurgery is being offered as an alternative. The patient can choose the treatment modality taking into account his/her age, sex and profession. (author). 13 refs.; 1 fig.; 4 tabs

    Full Text Available BACKGROUND: Radio-frequency ablation (RFA has been employed in the treatment of Barcelona Clinic Liver Cancer (BCLC early stage hepatocellular carcinoma (HCC as curative treatments. AIM: To assess the effectiveness and the safety of RFA in patients with early HCC and compensated cirrhosis. METHODS: A cohort of 151 consecutive patients with early stage HCC (122 Child-Pugh class A and 29 class B patients treated with RFA were enrolled. Clinical, laboratory and radiological follow-up data were collected from the time of first RFA. A single lesion was observed in 113/151 (74.8%, two lesions in 32/151 (21.2%, and three lesions in 6/151 (4% of patients. RESULTS: The overall survival rates were 94%, 80%, 64%, 49%, and 41% at 12, 24, 36, 48 and 60 months, respectively. Complete response (CR at 1 month (p<0.0001 and serum albumin levels (p = 0.0004 were the only variables indipendently linked to survival by multivariate Cox model. By multivariate analysis, tumor size (p = 0.01 is the only variable associated with an increased likehood of CR. The proportion of major complications after treatment was 4%. CONCLUSIONS: RFA is safe and effective for managing HCC with cirrhosis, especially for patients with HCC ≤3 cm and higher baseline albumin levels. Complete response after RFA significantly increases survival.

  15. The apparent diffusion coefficient of a primary lesion correlates with local failure of head and neck squamous cell carcinoma treated with radiotherapy. President award proceedings

    International Nuclear Information System (INIS)

    We prospectively investigated whether the value of the apparent diffusion coefficient (ADC) of a primary lesion prior to treatment correlated with local failure of head and neck squamous cell carcinoma (HNSCC) following radiotherapy. In 17 patients who underwent radiotherapy for primary HNSCC, we compared variables considered to affect local failure, including parameters related to magnetic resonance (MR) imaging, such as ADC and its alteration ratio, between cases of local failure and controls and analyzed survival among those patients in whom the variables differed or demonstrated association with local failure. We also retrospectively analyzed variables in a validation study of 40 patients. In the prospective study, pretreatment values of ADChigh (calculated with b-values of 300, 500, 750, and 1000 s/mm2) alone showed significant association with local failure (P=0.0186). In the validation study, pretreatment values of tumor volume (P=0.0217) and ADChigh (P=0.0001) were significantly associated with local failure. Pretreatment ADChigh was superior to pretreatment tumor volume regarding association with local failure. These results suggest that pretreatment values of both ADC obtained using high b-values and tumor volume correlate with local failure of HNSCC treated with radiotherapy. (author)

    Purpose: To determine 20-year rates of local control and outcome-associated factors for ductal carcinoma in situ (DCIS) after breast-conserving therapy (BCT). Methods and Materials: All DCIS cases receiving BCT between 1980 and 1993 were reviewed. Patient demographics and pathologic factors were analyzed for effect on outcomes, including ipsilateral breast tumor recurrence (IBTR) and survival. Results: One hundred forty-five cases were evaluated; the median follow-up time was 19.3 years. IBTR developed in 25 patients, for 5-, 10-, 15-, and 20-year actuarial rates of 9.9%, 12.2%, 13.7%, and 17.5%, respectively. One third of IBTRs were elsewhere failures, and 68% of IBTRs occurred <10 years after diagnosis. Young age and cancerization of lobules predicted for IBTR at <10 years, and increased slide involvement and atypical ductal hyperplasia were associated with IBTR at later time points. Conclusions: Patients with DCIS treated with BCT have excellent long-term rates of local control. Predictors of IBTR vary over time, and the risk of recurrence seems highest within 10 to 12 years after diagnosis.

  17. Baseline Serum Lactate Dehydrogenase Levels for Patients Treated With Intensity-Modulated Radiotherapy for Nasopharyngeal Carcinoma: A Predictor of Poor Prognosis and Subsequent Liver Metastasis

    International Nuclear Information System (INIS)

    Purpose: To evaluate the prognostic value of baseline serum lactate dehydrogenase (LDH) levels in patients with nasopharyngeal carcinoma (NPC) treated with intensity-modulated radiotherapy (IMRT). Methods and Materials: Cases of NPC (n = 465) that involved treatment with IMRT with or without chemotherapy were retrospectively analyzed. Results: The mean (±SD) and median baseline serum LDH levels for this cohort were 172.77 ± 2.28 and 164.00 IU/L, respectively. Levels of LDH were significantly elevated in patients with locoregionally advanced disease (p = 0.016). Elevated LDH levels were identified as a prognostic factor for rates of overall survival (OS), disease-free survival (DFS), and distant metastasis-free survival (DMFS), with p values <0.001 in the univariate analysis and p < 0.001, p = 0.004, and p = 0.003, respectively, in the multivariate analysis. Correspondingly, the prognostic impact of patient LDH levels was found to be statistically significant for rates of OS, DFS, and DMFS (p = 0.028, 0.024, and 0.020, respectively). For patients who experienced subsequent liver failure after treatment, markedly higher pretreatment serum LDH levels were detected compared with patients experiencing distant metastasis events at other sites (p = 0.032). Conclusions: Elevated baseline LDH levels are associated with clinically advanced disease and are a poor prognosticator for OS, DFS, and DMFS for NPC patients. These results suggest that elevated serum levels of LDH should be considered when evaluating treatment options.

  18. Outcomes of patients with loco-regionally recurrent or new primary squamous cell carcinomas of the head and neck treated with curative intent reirradiation at Mayo Clinic

    International Nuclear Information System (INIS)

    We reviewed outcomes of patients with loco-regionally recurrent (LRR) or new primary (NP) squamous cell carcinoma of the head and neck (SCCHN) treated at our institution with reirradiation (RRT). Patients received definitive RRT (DRRT) or post-operative RRT following salvage surgery (PRRT) from 2003 to 2011. Measured survival outcomes included loco-regional relapse free survival (LRFS) and overall survival (OS). Among 81 patients (PRRT, 42; DRRT, 39), median PRRT and DRRT doses were 60 Gy (12–70 Gy) and 69.6 Gy (48–76.8 Gy). The majority of patients received IMRT-based RRT (n = 77, 95 %). With median follow-up of 78.1 months (95 % CI, 56–96.8 months), 2-year OS was 53 % with PRRT and 48 % with DRRT (p = 0.12); 23 % of patients were alive at last follow-up. LRFS at 2 years was 60 %, and did not differ significantly between PRRT and DRRT groups. A trend toward inferior LRFS was noted among patients receiving chemotherapy with RRT versus RRT alone (p = 0.06). Late serious toxicities were uncommon, including osteoradionecrosis (2 patients) and carotid artery bleeding (1 patient, non-fatal). OS of PRRT- and DRRT-treated patients in this series appears superior to the published literature. We used IMRT for the majority of patients, in contrast to several series and trials previously reported, which may account in part for this difference. Future studies should seek to improve outcomes among patients with LRR/NP SCCHN via alternative therapeutic modalities such as proton radiotherapy and by incorporating novel systemic agents

    Full Text Available We should accept that there are attempts in all over the world to do much less invasive treatments especially in surgical procedures. Nowadays, one of the interest areas of urologists is conservative management of upper urinary tract urothelial cancers (UUTCs. Is nephroureterectomy an overtreatment for all cases or which cases are eligible for minimally invasive therapy in UUTC. Recently, the European Association of Urology guidelines accepted conservative endoscopic treatment using ureterenoscopy for a selected group of UUTC patients with low-volume, low-grade, and low-stage disease. This study tried to explain a new technique, confocal laser endomicroscopy (CLE, for increasing accuracy of sampling in UUTC and improving the conservative management. CLE is an ultrahigh-resolution microscopy technique that allows imaging of tissue at a depth of 400 µm. A negative point for CLE is the sensitivity to tissue movement leading to motion artifacts that could result in blurred images. In other studies, the benefit of CLE was shown in colon, gastric and bronchial pathologies which are luminal organs like urinary tract. Eleven patients were enrolled in this study. Four patients were previously treated endoscopically and one patient had positive cytology with no evidence of a disease in the bladder. A digital ureteroscope Flex-XC was used in all cases. After fluorescein injection, real time video sequences were acquired. Biopsies were obtained from the suspicious lesions. According to CLE findings, there were three high-grade, seven low-grade tumors and one negative tumor. Biopsy findings revealed with four not reliable, one inflammation (negative one in CLE, one dysplasia, four low-grade tumors and one highgrade tumor. It is very hard to comment on a new technique with a small amount of patients. May be it is better to say the cliché words: This study should be confirmed or validated by wide variety of studies. In addition, although this study showed

    We assessed the prognostic value of metabolic tumor volume (MTV) measured using {sup 18F} fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) inpatients with locally advanced head and neck squamous cell carcinoma (HNSCC). We retrospectively reviewed 56 patients (51 men, five women; mean age 56.0{+-}8.8 years) who had locally advanced HNSCC and underwent FDG PET/CT for initial evaluation. All patients had surgical resection and radiotherapy with or without concurrent chemotherapy. The peak standardized uptake (SUV{sup peak)} and MTV of the target lesion, including primary HNSCC and metastatic cervical lymph nodes, were measured SUV{sup peak,} MTV, and clinico pathologic variables such as age, Eastern Cooperative Oncology Group (ECOG) performance status, pN stage, pT stage, TNM stage, histologic grade and treatment modality to disease free survival (DFS) and overall survival (OS). On the initial FDG PET/CT scans, the median SUV{sup peakw}as 7.8 (range, 1.8-19.0) and MTV was 17.0cm{sup 3(}range, 0.1-131.0cm{sup 3)}. The estimated 2 year DFS and OS rates were 67.2% and 81.8%. The cutoff points of SUV{sup peak6}.2 and MTV 20.7cm{sup 3w}ere the best discriminative values for predicting clinical outcome. MTV and ECOG performance status were significantly related to DFS and OS on univariate and multivariate analyses (P=0.05). The MTV obtained from initial FDG PET/CT scan is a significant prognostic factor for disease recurrence and mortality in locally advanced HNSCC treated with surgery and radiotherapy with or without chemotherapy.

  4. Outcomes in a Multi-institutional Cohort of Patients Treated With Intraoperative Radiation Therapy for Advanced or Recurrent Renal Cell Carcinoma

    International Nuclear Information System (INIS)

    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

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

    Purpose: A subset of patients with oropharyngeal squamous cell carcinoma (OP-SCC) managed with transoral robotic surgery (TORS) and postoperative radiation therapy (PORT) developed soft tissue necrosis (STN) in the surgical bed months after completion of PORT. We investigated the frequency and risk factors. Materials and Methods: This retrospective analysis included 170 consecutive OP-SCC patients treated with TORS and PORT between 2006 and 2012, with >6 months' of follow-up. STN was defined as ulceration of the surgical bed >6 weeks after completion of PORT, requiring opioids, biopsy, or hyperbaric oxygen therapy. Results: A total of 47 of 170 patients (28%) had a diagnosis of STN. Tonsillar patients were more susceptible than base-of-tongue (BOT) patients, 39% (41 of 104) versus 9% (6 of 66), respectively. For patients with STN, median tumor size was 3.0 cm (range 1.0-5.6 cm), and depth of resection was 2.2 cm (range 1.0-5.1 cm). Median radiation dose and dose of fraction to the surgical bed were 6600 cGy and 220 cGy, respectively. Thirty-one patients (66%) received concurrent chemotherapy. Median time to STN was 2.5 months after PORT. All patients had resolution of STN after a median of 3.7 months. Multivariate analysis identified tonsillar primary (odds ratio [OR] 4.73, P=.01), depth of resection (OR 3.12, P=.001), total radiation dose to the resection bed (OR 1.51 per Gy, P<.01), and grade 3 acute mucositis (OR 3.47, P=.02) as risk factors for STN. Beginning May 2011, after implementing aggressive avoidance of delivering >2 Gy/day to the resection bed mucosa, only 8% (2 of 26 patients) experienced STN (all grade 2). Conclusions: A subset of OP-SCC patients treated with TORS and PORT are at risk for developing late consequential surgical bed STN. Risk factors include tonsillar location, depth of resection, radiation dose to the surgical bed, and severe mucositis. STN risk is significantly decreased with carefully avoiding a radiation dosage of >2 Gy/day to

    Purpose: To examine the prognostic significance of c-Met expression in relation to p16 and epidermal growth factor receptor (EGFR) in patients with locally advanced head and neck squamous cell carcinoma (HNSCC) treated with definitive concurrent chemoradiation. Methods and Materials: Archival tissue from 107 HNSCC patients treated with chemoradiation was retrieved, and a tissue microarray was assembled. Immunohistochemical staining of c-Met, p16, and EGFR was performed. c-Met expression was correlated with p16, EGFR, clinical characteristics, and clinical endpoints including locoregional control (LRC), distant metastasis (DM), disease-free survival (DFS), and overall survival (OS). Results: Fifty-one percent of patients were positive for p16, and 53% were positive for EGFR. Both p16-negative (P≤.001) and EGFR-positive (P=.019) status predicted for worse DFS. Ninety-three percent of patients stained positive for c-Met. Patients were divided into low (0, 1, or 2+ intensity) or high (3+ intensity) c-Met expression. On univariate analysis, high c-Met expression predicted for worse LRC (hazard ratio [HR] 2.27; 95% CI, 1.08-4.77; P=.031), DM (HR 4.41; 95% CI, 1.56-12.45; P=.005), DFS (HR 3.00; 95% CI, 1.68-5.38; P<.001), and OS (HR 4.35; 95% CI, 2.13-8.88; P<.001). On multivariate analysis, after adjustment for site, T stage, smoking history, and EGFR status, only high c-Met expression (P=.011) and negative p16 status (P=.003) predicted for worse DFS. High c-Met expression was predictive of worse DFS in both EGFR-positive (P=.032) and -negative (P=.008) patients. In the p16-negative patients, those with high c-Met expression had worse DFS (P=.036) than did those with low c-Met expression. c-Met expression was not associated with any outcome in the p16-positive patients. Conclusions: c-Met is expressed in the majority of locally advanced HNSCC cases, and high c-Met expression predicts for worse clinical outcomes. High c-Met expression predicted for worse DFS in p16

    Full Text Available Purpose: To ascertain factors that could influence the development of ulcers and strictures in the definitive management of squamous cell carcinoma (SCC of esophagus treated with external beam radiotherapy (EBRT, high-dose-rate (HDR intralumenal radiotherapy (ILRT with or without concurrent weekly cisplatin (CDDP @ 35 mg/m2 chemotherapy (CT. Materials and Methods: Between 1990-2005, 244 patients with inoperable SCC of esophagus were identified from our database and grouped into one of the following: those receiving at least 60Gy EBRT (Gp E, n=44; EBRT followed by HDR-ILRT (Gp E+I, n=98; at least 50Gy EBRT with CT (Gp E+C, n=68; EBRT+HDR-ILRT + CT (Gp E+I+C, n=34. Ulcers (discovered on endoscopy and strictures evident on a barium swallow (which needed dilatations were scored as treatment induced, if the biopsy was negative. Factors likely to influence their outcome were analyzed. Results: The groups were matched for all patient and disease characteristics except pretreatment hemoglobin and Karnofsky performance score (KPS, which were lower in Gp E. The incidence of ulcers was 7%, 8%, 6% and 21% ( P =0.08 while that of strictures was 14%, 9%, 21% and 41% ( P =0.00 for the groups E, E+I, E+C and E+I+C respectively.

Conclusion: Treatment intensification as in Gp E+I+C results in about a three-fold increase in treatment induced late morbidity which can adversely impact on swallowing function and therefore emphasizes the need for optimisation of HDR-ILRT when used in a CT+RT protocol.

  9. Vulvar carcinoma

    International Nuclear Information System (INIS)

    Purpose: Controversies exist regarding the use of radiation therapy in the treatment of vulvar carcinoma. A retrospective review was performed to evaluate our institution's experience with surgery and radiation for this disease. Methods and Materials: The medical records of 47 patients treated for squamous cell carcinoma of the vulva at our institution (1974-1992) were reviewed for TNM stage (AJCC criteria), treatment modality, and associated 5-year local control and survival based on Kaplan-Meier analysis. Results: Twenty-eight patients (60%) presented with Stage I and II disease and their 5-year survival was 69%. Stage III patients accounted for 12 (25%) of the patients and their 5-year survival was 73%. Seven patients presented with Stage IV disease and five died within 13 months of diagnosis after predominantly palliative therapy. The 40 patients with Stages I, II, and III disease were treated aggressively and were further evaluated for treatment-modality-associated survival and local control. Radiation therapy was used as primary treatment in nine patients, of whom seven were treated with radiation alone and two were treated postoperatively after wide excision. Surgery alone was performed in 31 patients consisting of either radical vulvectomy (20 patients) or wide excision (11 patients). When comparing outcomes of radical vulvectomy vs. radiation therapy, we noted that the 5-year actuarial survivals were comparable (74% for either modality), despite the presence of more favorable prognostic factors in the group treated with radical vulvectomy. Patients treated with wide excision alone had a trend for a poorer 5-year actuarial survival (51%) and local control (50%). Conclusions: Radical vulvectomy offers good locoregional control and survival. This retrospective review further supports the use of radiation therapy with conservative surgery as an alternative treatment option for patients with vulvar carcinoma treated with curative intent. In contrast, the use of

    Background: Predicting the efficacy of antiangiogenic therapy would be of clinical value in patients (pts) with metastatic renal cell carcinoma (mRCC). We tested the hypothesis that circulating endothelial cell (CEC), bone marrow-derived CD45dimCD34+VEGFR2+ progenitor cell or plasma angiogenic factor levels are associated with clinical outcome in mRCC pts undergoing treatment with tyrosine kinase inhibitors (TKI). Methods: Fifty-five mRCC pts were prospectively monitored at baseline (day 1) and day 14 during treatment (46 pts received sunitinib and 9 pts received sorafenib). Circulating endothelial cells (CD45−CD31+CD146+7-amino-actinomycin (7AAD)− cells) were measured in 1 ml whole blood using four-color flow cytometry (FCM). Circulating CD45dimCD34+VEGFR2+7AAD− progenitor cells were measured in progenitor-enriched fractions by four-color FCM. Plasma VEGF, sVEGFR2, SDF-1α and sVCAM-1 levels were determined by ELISA. Correlations between baseline CEC, CD45dimCD34+VEGFR2+7AAD− progenitor cells, plasma factors, as well as day 1–day 14 changes in CEC, CD45dimCD34+VEGFR2+7AAD− progenitor, plasma factor levels, and response to TKI, progression-free survival (PFS) and overall survival (OS) were examined. Results: No significant correlation between markers and response to TKI was observed. No association between baseline CEC, plasma VEGF, sVEGFR-2, SDF-1α, sVCAM-1 levels with PFS and OS was observed. However, baseline CD45dimCD34+VEGFR2+7AAD− progenitor cell levels were associated with PFS (P=0.01) and OS (P=0.006). Changes in this population and in SDF-1α levels between day 1 and day 14 were associated with PFS (P=0.03, P=0.002). Changes in VEGF and SDF-1α levels were associated with OS (P=0.02, P=0.007). Conclusion: Monitoring CD45dimCD34+VEGFR2+ progenitor cells, plasma VEGF and SDF-1α levels could be of clinical interest in TKI-treated mRCC pts to predict outcome. PMID:21386843

    Full Text Available Hepatocellular carcinoma rarely metastasizes to the orbit. We report a 45-year-old male, HBV+, HIV+, with a past history of a liver transplant for ELSD (end-stage liver disease with hepatocellular carcinoma and recurrent HCC, who presented with proptosis and diplopia of the left eye. CT scans of the head revealed a large, irregular mass in the left orbit causing superior and lateral destruction of the orbital bone. Biopsy specimens of the orbital tumor showed features of metastatic foci of hepatocellular carcinoma. Only 16 other cases of HCC metastasis to the orbit have been described in literature, and this is the first case in a previously transplanted HIV+, HBV+ patient.

  13. Impact of 3D image-based PDR brachytherapy on outcome of patients treated for cervix carcinoma in France: Results of the French STIC prospective study

    International Nuclear Information System (INIS)

    Purpose: In 2005 a French multicentric non randomized prospective study was initiated to compare two groups of patients treated for cervix carcinoma according to brachytherapy (BT) method: 2D vs 3D dosimetry. The BT dosimetric planning method was chosen for each patient in each center according to the availability of the technique. This study describes the results for 705 out of 801 patients available for analysis. Patients and methods: For the 2D arm, dosimetry was planned on orthogonal X-Rays using low dose rate (LDR) or pulsed dose rate (PDR) BT. For the 3D arm, dosimetry was planned on 3D imaging (mainly CT) and performed with PDR BT. Each center could follow the dosimetric method they were used to, according to the chosen radioelement and applicator. Manual or graphical optimization was allowed. Three treatment regimens were defined: Group 1: BT followed by surgery; 165 patients (2D arm: 76; 3D arm: 89); Group 2: EBRT (+chemotherapy), BT, then surgery; 305 patients (2D arm: 142; 3D arm: 163); Group 3: EBRT (+chemotherapy), then BT; 235 patients, (2D arm: 118; 3D arm: 117). The DVH parameters for CTVs (High Risk CTV and Intermediate Risk CTV) and organs at risk (OARs) were computed as recommended by GYN GEC ESTRO guidelines. Total doses were converted to equivalent doses in 2 Gy fractions (EQD2). Side effects were prospectively assessed using the CTCAEv3.0. Results: The 2D and 3D arms were well balanced with regard to age, FIGO stage, histology, EBRT dose and chemotherapy. For each treatment regimen, BT doses and volumes were comparable between the 2D and 3D arms in terms of dose to point A, isodose 60 Gy volume, dose to ICRU rectal points, and TRAK. Dosimetric data in the 3D arm showed that the dose delivered to 90% of the High Risk CTV (HR CTV D90) was respectively, 81.2 Gyα/β10, 63.2 Gyα/β10 and 73.1 Gyα/β10 for groups 1, 2 and 3. The Intermediate Risk (IR) CTV D90 was respectively, 58.5 Gyα/β10, 57.3 Gyα/β10 and 61.7 Gyα/β10 for groups 1, 2 and

    OBJECTIVE To investigate the relationship between the therapeutic modality and prognostic factors for the patients with T3N0~1M0 nasopharyngeal carcinoma.METHODS The clinical data from 127 cases of T3N0~1M0 nasopharyngeal carcinoma patients with initial treatment, during the period from January 4th, 2000 to November 12th, 2001, were retrospectively analyzed. The cases were divided into Group A with simple radiotherapy (90) and Group B with the radiation therapy combined with chemotherapy (37), based on various patients' conditions. In group B, inductive chemotherapywas conducted for 18 cases, inductive chemotherapy plus homochronous chemotherapy for 5 and homochronous chemotherapy for 14.RESULTS The 5-year overall survival (OS) in the groups A and B was 73.4% and 72.3% respectively (P>0.05); the cancer-correlated survival (CCS) in the 2 groups was 76.4% and 72.3% respectively (P>0.05); the disease-free survival (DFS) in group A and B was 65.5% and 71.7% respectively (P<0.05). A multiple analysis showed that the mode of radiation therapy plus chemotherapy was a favorable independent impact factor for DFS.CONCLUSION Chemotherapy plus radiotherapy can improve the DFS of patients with T3N0~1M0 nasopharyngeal carcinoma, but fails to prolong the survival time of the patients. The modality of chemotherapy plus radiotherapy is not the necessary choice in treatment of patients with T3N0~ 1M0 nasopharyngeal carcinoma.

    1997-12-01

    We reclassified 720 nonmedullary invasive thyroid carcinomas diagnosed and treated between 1975 and 1993. Twenty-seven cases met the criteria of insular carcinoma and 29 cases those of widely invasive follicular carcinoma. Comparison of these histotypes with respect to pathologic stage and overall, relative, and visceral metastasis-free survival showed a significant association between histotype and pT and pN categories. In particular, pT4 (p AAA transversion at codon 61 of the N-RAS gene in insular carcinoma. These findings suggest that insular carcinoma represents a de novo entity distinct from widely invasive follicular carcinoma, that widely invasive follicular carcinoma has biologic characteristics more consistent with poorly differentiated than well-differentiated carcinomas, and that both insular carcinoma and widely invasive follicular carcinoma share similar molecular alterations.

    Full Text Available We report a patient with metastatic clear-cell renal cell carcinoma (mRCC who presented with primary tumor in situ in the left kidney and metastases to bone, liver, lungs, and brain. After over 5 years of sunitinib therapy and subsequent cytoreductive left nephrectomy, the patient achieved radiographic complete response (CR and had pathologic CR in the nephrectomy specimen. Durable clinical and pathological CRs are possible with targeted agents, even with primary tumor in situ and widely disseminated metastases. Ongoing research will define the optimal duration of systemic therapy in exceptional responders and identify the molecular determinants of response and resistance.

  3. Healing results in dependence on the administered nominal standard dose in carcinoma of the oral cavity treated by combined surgical and radiological therapy

    International Nuclear Information System (INIS)

    Between 1972 and 1980, a homogenous group of 116 patients with squamous cell carcinomas in the oral cavity and the oropharynx underwent a combined surgical and radiological treatment. 36 out of them were submitted to a preoperative short-term irradiation with postoperative dose completion, the other 80 patients were only irradiated after the operation. The nominal standard dose (NSD) was calculated for all patients. The group submitted to preoperative short-term irradiation, having the same conditions apart from that, showed considerably less recurrences (13.9%) than the patients irradiated only after the operation (33.7%). Due to the shorter overall treatment period, higher average NSD values have been obtained in case of preoperative short-term irradiation. The authors discuss to what extent the better treatment results of pre- and postoperative irradiation are due to the devitalization effect or to the higher NSD values. The results show, however, that the fractionation scheme should be taken into special consideration in order to optimize the biologic radiation effect in the treatment of carcinomas of the oral cavity.

Materials and methods: Design. randomized, controlled, open study ('systematic percutaneous gastrostomy' versus 'no systematic gastrostomy'). Patients. squamous cell head and neck carcinoma (stages III and IV, UICC 1997). Setting. oncological departments of French university teaching hospitals. Treatment. optimal concomitant radio-chemotherapy. Evaluations. T0 baseline evaluation, T1 during the treatment, T2 end of the treatment, and T3 6-month post-inclusion. Primary endpoint. 6-month quality of life (Qol) assessed using SF36, EORTC QLQ-C30, EORTC QLQ H and N35 questionnaires. Results: The Qol changes from baseline included a decline (T1 and T2) followed by an improvement (T3). Qol at 6 months was significantly higher in the group receiving systematic prophylactic gastrostomy (p = 10-3). Higher initial BMI and lower initial Karnofsky index were significant factors related to a higher 6-month Qol. Conclusions: The study results suggest that prophylactic gastrostomy improves post-treatment quality of life for unresectable head and neck cancer patients, after adjusting for other potential predictive quality of life factors.

    Summary: Rarely, basal cell carcinoma grows to a giant size, invading the underlying deep tissue and complicating the treatment and reconstruction modalities. A giant basal cell carcinoma on the scalp is in some cases treated with a combination of surgery and radiation therapy, resulting in local control, a satisfactory long-term cosmetic and functional result. We present a case with a neglected basal cell scalp carcinoma, treated with wide excision and postoperative radiotherapy, reconstruct...

    Targeted alpha therapy (TAT) a promising treatment for small, residual, and micrometastatic diseases has questionable efficacy against malignant lesions larger than the α-particle range, and likely requires favorable intratumoral activity distribution. Here, we characterized and quantified the...... activity distribution of an alpha-particle emitter radiolabelled antibody within >100-µm micrometastases in a murine ovarian carcinoma model. Nude mice bearing ovarian micrometastases were injected intra-peritoneally with 211At-MX35 (total injected activity 6 MBq, specific activity 650 MBq/mg). Animals......% IA/g at 4 h) in the outer tumor layer and a sharp drop beyond a depth of 50 µm. Small-scale dosimetry was performed on a multi-cellular micrometastasis model, using time-integrated activities derived from the experimental data. With injected activity of 400 kBq, tumors exhibiting uniform activity...

  7. Energy and protein intake and nutritional status in non-surgically treated patients with small cell anaplastic carcinoma of the lung

    Energy Technology Data Exchange (ETDEWEB)

    Enig, B.; Winther, E.; Hessov, I.

    The spontaneous food intake and nutritional status was assessed in 23 patients with small cell anaplastic carcinoma of the lung before and two times during a treatment period of 6 weeks. Radiation therapy was given for 2 weeks followed by a course of chemotherapy and another 2 weeks of radiation therapy. The energy intake decreased during the treatment from 146 to 130 per cent of basal metabolic rate. The protein intake remained unchanged (mean 0.9 g/kg body weight). There were insignificant and small losses of weight, body fat, free body mass and arm muscle circumference, and no changes were seen in serum albumin and serum transferrin. However, 6 patients suffered a weight loss of 5 per cent or more. No correlation existed between the nutritional parameters measured before treatment and the changes during treatment. Patients who suffered a loss of body weight could therefore not be singled out before the treatment.

  8. Comparison of different application systems and CT-assisted treatment planning procedures in the treatment of primary endometrium carcinoma. Is it technically possible to include the whole uterus volume in the volume treated by brachytherapy?

    International Nuclear Information System (INIS)

    In a consecutive series of 10 patients with primary irradiated endometrial carcinoma we analyzed the correlation between target volume and treated volume using either standard 1-channel applicators or individual Heyman-applicators. Application of the ovoids was followed by a planning CT scan for all patients. Based on this, target volume (uterus volume) was estimated on a 3D-planning system. According to the measurable length of the uterus cavity we determined the corresponding standard 1-channel applicator and calculated the respectively treated volume. Estimating the advantages of an optimized treatment planning strategy for individual Heyman-applications we compared the treated volumes, which result from a standardized and optimized treatment planning procedure. The mean uterus volume was 180 cm3 (range 57 to 316 cm3). Asymmetric uterus configurations with longitudinal or sagittal side differences exceeding 1 cm were found in 40% of the cases. Using standard 1-channel applicators on average 47% (range 25 to 89%) of the uterus volume were enclosed by the treated volume compared to 70% for Heyman-applications. Differentiating these individual applications according to the variable treatment modality values of mean 66% (range 36 to 110%) for the standardized and 73% (range 48 to 95%) for the optimized treatment planning strategy were found. Moreover optimized planning modalities led to an improved coverage of the target volume in 5 out of 10 cases with an increase in volume of 20% on average (range 11 to 32%). In 3 cases changes of less than 5% were noticed (no improvement). In order to protect organs at risk treated volume had to be decreased in 2 cases for 19% and 40% respectively. (orig./MG)

    OBJECTIVE To conduct a comparative study of the effects of treatment using microwave ablation versus surgical resection on hematogenous dissemination of cancer cells, and on the level of immune cells of the peripheral blood in patients with small primary hepatocellular carcinoma (PHC, ≤5 cm).METHODS Forty patients with small PHC (maximal diameter ≤5 cm) were divided into a microwave group (19 cases) and a surgical operation group (21 cases). A real-time (RT) quantitative nested RT-PCR examination was performed for peripheral blood alpha-fetoprotein (AFP) mRNA. Studies were conducted to determine the level of CD3, CD4, CD8 and CD4/CD8 cells and for liver function at 30 min before, and 30 min,1 day and 3 days after the treatment.RESULTS Compared to the value before ablation, no obvious changes of CD3, CD4, CD8 and CD4/CD8 cells were found in patients of the microwave group within 7 days after ablation, but CD3, CD4 and CD4/CD8 cells in the operation group were lower compared to that before operatioh. The copy number of AFP mRNA in the peripheral blood samples of the patients of the 2 groups before operation was determined in 67.5% of the patients (27/40). There was an rise in the expression after treatment but no statistical difference was found in comparing the 2 groups. Follow-up of the patients was conducted for 1 to 16 months. For patients with continuous expression of peripheral blood AFP mRNA, the possibility of relapse and metastasis was increased.CONCLUSION Surgical resection or microwave ablation can cause more exfoliation of hepatoma carcinoma cells in the peripheral blood of patients with small PHC. The immune function of peripheral blood cells decreased in the patients after surgical resection, however, the immune function was better protected following microwave ablation. Microwave ablation causes minor reduction in liver function, and the treatment method presents a definite value for PHC therapy.

    Full Text Available OBJECTIVE: Non-small cell lung carcinoma (NSCLC is the most common type of lung cancer. Most patients are diagnosed at an advanced stage, palliative chemotherapy therefore being the only treatment option. This study was aimed at evaluating the health-related quality of life (HRQoL of advanced-stage NSCLC patients receiving palliative chemotherapy with carboplatin and paclitaxel. METHODS: This was a multiple case study of advanced-stage NSCLC outpatients receiving chemotherapy at a public hospital in Rio de Janeiro, Brazil. The European Organization for Research and Treatment of Cancer Core Quality of Life Questionnaire was used in conjunction with its supplemental lung cancer-specific module in order to assess HRQoL. RESULTS: Physical and cognitive functioning scale scores differed significantly among chemotherapy cycles, indicating improved and worsened HRQoL, respectively. The differences regarding the scores for pain, loss of appetite, chest pain, and arm/shoulder pain indicated improved HRQoL. CONCLUSIONS: Chemotherapy was found to improve certain aspects of HRQoL in patients with advanced-stage NSCLC.

    Full Text Available Although both oxidative stress and microRNAs (miRNAs play vital roles in physiological and pathological processes, little is known about the interactions between them. In this study, we first described the regulation of H2O2 in cell viability, proliferation, cycle, and apoptosis of human hepatocellular carcinoma cell line HepG2. Then, miRNAs expression was profiled after H2O2 treatment. The results showed that high concentration of H2O2 (600 μM could decrease cell viability, inhibit cell proliferation, induce cell cycle arrest, and finally promote cell apoptosis. Conversely, no significant effects could be found under treatment with low concentration (30 μM. miRNAs array analysis identified 131 differentially expressed miRNAs (125 were upregulated and 6 were downregulated and predicted 13504 putative target genes of the deregulated miRNAs. Gene ontology (GO analysis revealed that the putative target genes were associated with H2O2-induced cell growth arrest and apoptosis. The subsequent bioinformatics analysis indicated that H2O2-response pathways, including MAPK signaling pathway, apoptosis, and pathways in cancer and cell cycle, were significantly affected. Overall, these results provided comprehensive information on the biological function of H2O2 treatment in HepG2 cells. The identification of miRNAs and their putative targets may offer new diagnostic and therapeutic strategies for liver cancer.

    The present study evaluated whether flurbiprofen increased the naturally circulating dendritic cells (DCs) subsets in patients with esophageal squamous cell carcinoma (ESCC) undergoing esophageal resection. Compared to healthy donors (n=20), the significantly depressed percentages of plasmacytoid DCs (pDCs), CD1c+ myeloid DCs (mDCs), and CD141+ mDCs among ESCC patients (n=60) were confirmed. Flurbiprofen was administered before skin incision and at the end of operation in group F (n=30), as well as placebo in group C (n=30). The postoperative suppressed percentages of pDCs, CD1c+ mDCs, and CD141+ mDCs increased significantly following the perioperative treatment with flurbiprofen. Flurbiprofen also significantly stimulated the postoperative IFN-f and IL-17 production, but inhibited the immunosuppressive IL-10 and TGF-β levels. Furthermore, flurbiprofen exerted a similar analgesic effect and brought a significantly less sufentanil consumption compared to group C. Taken together, flurbiprofen provided a short-term increase of postoperative naturally circulating DCs in ESCC patients. PMID:26959879

  16. Randomized phase III trial (GORTEC 98-03) comparing re-irradiation plus chemotherapy versus methotrexate in patients with recurrent or a second primary head and neck squamous cell carcinoma, treated with a palliative intent

    International Nuclear Information System (INIS)

    Purpose: This randomized phase III trial investigated the potential benefit of concurrent re-irradiation, fluorouracil and hydroxyurea versus methotrexate for patients treated with palliative intent for recurrent or second primary head and neck squamous cell carcinoma (HNSCC) in previously irradiated area. Patients and methods: Patients with recurrent HNSCC or a second primary not amenable to curative-intent treatment were randomized to the R-RT arm (concurrent re-irradiation, fluorouracil and hydroxyurea) or to the Ch-T arm (methotrexate). The primary endpoint was overall survival (OS). Due to a very slow accrual, the trial was closed after inclusion of 57 patients. Results: Fifty-seven patients were included. All patients died in the two arms with a maximal follow-up of 5 years. Although four complete responses were achieved in R-RT arm, (none in Ch-T arm) re-irradiation did not improve OS compared with methotrexate (23% versus 22% at 1 year, NS). Sixteen patients experienced clinical grade ≥3 late toxicities (>6 months), 11 in R-RT arm and five in Ch-T arm. Conclusions: Premature discontinuation of the trial did not allow us to draw firm conclusions. However, there was no suggestion that concurrent re-irradiation, fluorouracil and hydroxyurea improved OS compared to methotrexate alone in patients treated with palliative intent for a recurrent or second primary HNSCC.

    International Nuclear Information System (INIS)

    The results presented in this paper are based upon information obtained from a critical review of 601 records of nasopharyngeal carcinoma retrieved from the files of the Cancer Institute. The records cover a period of 22 years. An analysis of the age and sex distribution revealed a male excess with a ratio of 2.2:1. No other significant age and sex differences were elucidated. About 80% of all the patients were found to manifest Stage II lesions. Early signs and symptoms were usually mild and non-incapacitating, which the patients usually ignored and may have misled the general practitioners. Single biopsy studies were conducted on 429 patients. The results have shown that more than 95% showed the presence of cell types I, III and IV, (36%, 31%, 31%, respectively), and these were mostly seen in patients manifesting Stage II lesions. Whether the cell type/stage relationship as observed is the true picture could not be ascertained, since the majority of the patients manifested Stage II lesions. The cell type(s) may however be an important factor in the evaluation of biologic response to radiotherapy and may further influence the dose/response relationship. Using port sizes of 6cm x 7cm to 6cm x 8cm, 178 patients were irradiated with doses ranging from about 4000 to 7000 rad (40-70Gy). The results have shown that 74 to 78% of the patients showing a 100% response (complete disappearance of the mass) were irradiated with doses in the range 5000 to 7000 rad (50 to 70Gy). 4000 to 5000 rad (40-50Gy) on the average resulted in optimum response rates to whole-neck irradiation.

    Full Text Available Abstract Background The SINS trial (Controlled Clinical Trials ISRCTN48755084; Eudract No. 2004-004506-24 is a randomised controlled trial evaluating long term success of excisional surgery vs. imiquimod 5% cream for low risk nodular and superficial basal cell carcinoma (BCC. The trial included a discrete choice experiment questionnaire to explore patient preferences of a cream versus surgery for the treatment of their skin cancer. Methods The self-completed questionnaire was administered at baseline to 183 participants, measuring patients’ strength of preferences when choosing either alternative ‘surgery’ or ‘imiquimod cream’ instead of a fixed ‘current situation’ option (of surgical excision as standard practice in UK. The treatments were described according to: cost, chance of complete clearance, side effects and appearance. Participants had to choose between various scenarios. Analysis was performed using a mixed logit model, which took into account the impact of previous BCC treatment and sample preference variability. Results The analysis showed that respondents preferred ‘imiquimod cream’ to their ‘current situation’ or ‘surgery’, regardless of previous experience of BCC symptoms and treatment. Respondents were more likely to be worried about their cosmetic outcomes and side effects they might experience over and above their chance of clearance and cost. Those with no experience of surgery (compared with experience valued more the choice of ‘imiquimod cream’ (£1013 vs £781. All treatment characteristics were significant determinants of treatment choice, and there was significant variability in the population preferences for all of them. Conclusions Patients with BCC valued more ‘imiquimod cream’ than alternative ‘surgery’ options, and all treatment characteristics were important for their choice of care. Understanding how people with a BCC value alternative interventions may better inform the

    The objective of this study was to investigate the significance of changes from the standard dosing schedule of sunitinib, which is 4 weeks of treatment and 2 weeks off (schedule 4/2), to an alternative schedule with 2 weeks of treatment and 1 week off (schedule 2/1), after encountering dose-limiting toxicity in 45 consecutive Japanese patients with metastatic renal cell carcinoma (mRCC). Despite a definitively improved relative dose intensity of sunitinib by changing from schedule 4/2 to 2/1, this difference was not significant. Adverse events (AEs) occurred in all patients on both schedules 4/2 and 2/1; however, the proportion of patients experiencing AEs ≥ grade 3 on schedule 2/1 was significantly lower than that on schedule 4/2. Quality of life (QOL) analysis using SF-36 revealed that all eight scores during schedule 2/1 were more favorable than those during schedule 4/2, and there were significant differences in 2 of the 8 scores between these two schedules. Furthermore, multivariate analyses, which were performed to evaluate the contribution of several AEs on schedule 2/1 to the improvement of each score in SF-36, revealed that fatigue had independent impacts on two scores, despite the lack of an independent association between any scores and the remaining AEs examined. These findings suggest that schedule 2/1 is the optimal dosing schedule of sunitinib against mRCC that balances efficacy and toxicity, since treatment on schedule 2/1 resulted in a markedly improved QOL compared with that on schedule 4/2 by relieving the profile of sunitinib-related AEs.

  1. BRCA1 mRNA expression as a predictive and prognostic marker in advanced esophageal squamous cell carcinoma treated with cisplatin- or docetaxel-based chemotherapy/chemoradiotherapy.

    Yong Gao

    Full Text Available BACKGROUND: The molecular backgrounds that determine therapeutic effectiveness in esophageal cancer remain largely unknown. Breast cancer susceptibility gene 1 (BRCA1 expression has been found to switch the response to cisplatin- or paclitaxel-based chemotherapy. It remains unclear how variations in BRCA1 expression influence clinical outcomes in esophageal cancer. PATIENTS AND METHODS: Quantitative real-time polymerase chain reaction (qPCR was performed to examine BRCA1 mRNA expressions in paraffin-embedded specimens from 144 patients with advanced or metastatic esophageal squamous cell carcinoma who received cisplatin- or docetaxel-based first-line treatments. RESULTS: Low BRCA1 mRNA expression correlated with increased response rate (RR; P = 0.025 and 0.017, respectively and median overall survival (mOS; P = 0.002 and P<0.001, respectively in cisplatin-based chemotherapy or chemoradiotherapy group and also correlated with decreased RR (P = 0.017 and 0.024, respectively and mOS (both P<0.001 in docetaxel-based chemotherapy or chemoradiotherapy group. Multivariate analysis revealed that low BRCA1 expression was an independent prognostic factor in cisplatin-based chemotherapy (HR 0.29; 95%CI 0.12-0.71; P = 0.007 or chemoradiotherapy (HR 0.12; 95%CI 0.04-0.37; P<0.001 group and higher risk for mortality in docetaxel-based chemotherapy (HR 5.02; 95%CI 2.05-12.28; P<0.001 or chemoradiotherapy (HR 7.02; 95%CI 2.37-27.77; P<0.001 group. CONCLUSIONS: BRCA1 mRNA expression could be used as a predictive and prognostic marker in esophageal cancer who underwent first-line cisplatin- or docetaxel-based treatments.

    Hypothyroidism in patients with metastatic renal cell carcinoma (mRCC) during treatment with the tyrosine kinase inhibitors (TKIs) sunitinib and sorafenib is a well-established side effect. Furthermore, the potential role of hypothyroidism as predictive marker of outcome has been studied but with conflicting results. The aim of the present meta-analysis was to assess the predictive value of hypothyroidism for progression-free (PFS) and overall survival (OS) in patients with mRCC during TKI therapy. We searched PubMed and the electronic abstract databases of the major international congresses' proceedings to identify all eligible studies that reported a correlation between the development of hypothyroidism during TKI treatment and outcome in patients with mRCC. Hazard ratios (HRs) with 95% confidence intervals (CIs) for PFS and OS were obtained from these publications and pooled in a meta-analysis. Eleven studies with a total of 500 patients fulfilled the inclusion criteria. We found no statistical significant difference in PFS between patients who developed hypothyroidism during sunitinib therapy and unaffected patients (HR, 0.82; 95% CI, 0.59-1.13; P = .22; 6 studies; 250 patients). The HR for OS was 0.52 (95% CI, 0.31-0.87; P = .01) for patients who developed hypothyroidism during sunitinib therapy compared with patients who did not (4 studies; 147 patients). The development of hypothyroidism during TKI therapy is not clearly shown to be predictive of efficacy in patients with mRCC. The observed advantage in OS for the patients with acquired hypothyroidism should be interpreted with caution.

  3. Impact of adverse events, treatment modifications, and dose intensity on survival among patients with advanced renal cell carcinoma treated with first-line sunitinib: a medical chart review across ten centers in five European countries

    International Nuclear Information System (INIS)

    Angiogenesis inhibitors have become standard of care for advanced and/or metastatic renal cell carcinoma (RCC), but data on the impact of adverse events (AEs) and treatment modifications associated with these agents are limited. Medical records were abstracted at 10 tertiary oncology centers in Europe for 291 patients ≥18 years old treated with sunitinib as first-line treatment for advanced RCC (no prior systemic treatment for advanced disease). Logistic regression models were estimated to compare dose intensity among patients who did and did not experience AEs during the landmark periods (18, 24, and 30 weeks). Cox proportional hazard models were used to explore the possible relationship of low-dose intensity (defined using thresholds of 0.7, 0.8, and 0.9) and treatment modifications during the landmark periods to survival. 64.4% to 67.9% of patients treated with sunitinib reported at least one AE of any grade, and approximately 10% of patients experienced at least one severe (grade 3 or 4) AE. Patients reporting severe AEs were statistically significantly more likely to have dose intensities below either 0.8 or 0.9. Dose intensity below 0.7 and dose discontinuation during all landmark periods were statistically significantly associated with shorter survival time. This study of advanced RCC patients treated with sunitinib in Europe found a significant relationship between AEs and dose intensity. It also found correlations between dose intensity and shorter survival, and between dose discontinuation and shorter survival. These results confirm the importance of tolerable treatment and maintaining dose intensity

    We reported previously that 18F-2-fluoro-2-deoxyglucose positron emission tomography/ computed tomography (FDG PET/CT) had potential for evaluating early response to treatment by tyrosine kinase inhibitors (TKIs) in advanced renal cell carcinoma (RCC). This time we investigated the relation of the early assessment by FDG PET/CT to long-term prognosis with an expanded number of patients and period of observation. Patients for whom TKI treatment for advanced RCC was planned were enrolled. FDG PET/CT was performed before TKI treatment and after one month of TKI treatment. The relations of the FDGPET/CT assessment to progression free survival (PFS) and overall survival (OS) were investigated. Thirty-five patients were enrolled (sunitinib 19 cases, sorafenib 16 cases). The patients with RCC showing high SUVmax in pretreatment FDG PET/CT demonstrated short PFS (P =0.024, hazard ratio 1.137, 95% CI 1.017-1.271) and short OS (P =0.004, hazard ratio 1.210 95% CI 1.062-1.379). Thirty patients (sunitinib 16 cases, sorafenib 14 cases) were evaluated again after 1 month. The PFS of the patients whose SUVmax decreased<20% was shorter than that of the patients whose SUVmax decreased<20% (P = 0.027, hazard ratio 3.043, 95% CI 1.134-8.167). The PFS of patients whose tumor diameter sum increased was shorter than that of the patient with tumors whose diameter sum did not (P =0.006, hazard ratio 4.555, 95% CI 1.543-13.448). The patients were classified into three response groups: good responder (diameter sum did not increase, and SUVmax decreased ≥ 20%), intermediate responder (diameter sum did not increase, and SUVmax decreased<20%), and poor responder (diameter sum increased, or one or more new lesions appeared). The median PFS of good, intermediate, and poor responders were 458 ± 146 days, 131 ± 9 days, and 88 ± 26 days (good vs. intermediate P = 0.0366, intermediate vs. poor P = 0.0097, log-rank test). Additionally the mean OSs were 999 ± 70 days, 469 ± 34 days, and 374

    Purpose: To compare, in a retrospective study, the toxicity and efficacy of simultaneous integrated boost using intensity-modulated radiotherapy (IMRT) vs. conventional radiotherapy (CRT) in patients treated with concomitant carboplatin and 5-fluorouracil for locally advanced oropharyngeal cancer. Methods and Materials: Between January 2000 and December 2007, 249 patients were treated with definitive chemoradiation. One hundred patients had 70 Gy in 33 fractions using IMRT, and 149 received CRT at 70 Gy in 35 fractions. Overall survival, disease-free survival, and locoregional control were estimated using the Kaplan-Meier method. Results: Median follow-up was 42 months. Three-year actuarial rates for locoregional control, disease-free survival, and overall survival were 95.1% vs. 84.4% (p = 0.005), 85.3% vs. 69.3% (p = 0.001), and 92.1% vs. 75.2% (p < 0.001) for IMRT and CRT, respectively. The benefit of the radiotherapy regimen on outcomes was also observed with a Cox multivariate analysis. Intensity-modulated radiotherapy was associated with less acute dermatitis and less xerostomia at 6, 12, 24, and 36 months. Conclusions: This study suggests that simultaneous integrated boost using IMRT is associated with favorable locoregional control and survival rates with less xerostomia and acute dermatitis than CRT when both are given concurrently with chemotherapy.

    Purpose: To retrospectively assess the influence of prophylactic cranial irradiation (PCI) timing on brain relapse rates in patients treated with two different chemoradiotherapy (CRT) regimens for Stage IIIB non-small-cell lung cancer (NSCLC). Methods and Materials: A cohort of 134 patients, with Stage IIIB NSCLC in recursive partitioning analysis Group 1, was treated with PCI (30 Gy at 2 Gy/fr) following one of two CRT regimens. Regimen 1 (n = 58) consisted of three cycles of induction chemotherapy (ICT) followed by concurrent CRT (C-CRT). Regimen 2 (n = 76) consisted of immediate C-CRT during thoracic radiotherapy. Results: At a median follow-up of 27.6 months (range, 7.2-40.4), 65 patients were alive. Median, progression-free, and brain metastasis-free survival (BMFS) times for the whole study cohort were 23.4, 15.4, and 23.0 months, respectively. Median survival time and the 3-year survival rate for regimens 1 and 2 were 19.3 vs. 26.1 months (p = 0.001) and 14.4% vs. 34.4% (p < .001), respectively. Median time from the initiation of primary treatment to PCI was 123.2 (range, 97-161) and 63.4 (range, 55-74) days for regimens 1 and 2, respectively (p < 0.001). Overall, 11 (8.2%) patients developed brain metastasis (BM) during the follow-up period: 8 (13.8%) in regimen 1 and 3 (3.9%) in regimen 2 (p = 0.03). Only 3 (2.2%) patients developed BM at the site of first failure, and for 2 of them, it was also the sole site of recurrence. Median BMFS for regimens 1 and 2 were 17.4 (13.5-21.3) vs. 26.0 (22.9-29.1 months), respectively (p < 0.001). Conclusion: These results suggest that in Stage IIIB NSCLC patients treated with PCI, lower BM incidence and longer survival rates result from immediate C-CRT rather than ITC-first regimens. This indicates the benefit of earlier PCI use without delay because of induction protocols.

    Full Text Available This study was to examine the effects of acupressure on fatigue and depression in HCC patients undergoing TACE. A quasiexperimental study design was used. Patients were evaluated at five time points: before treatment (T1 and 2, 3, 4, and 5 days after treating TACE (T2, T3, T4, and T5. Fatigue and depression were assessed by a VAS fatigue scale and a VAS depression scale at each time point. TFRS and BDI were administered at T1 and T5. Patients’ fatigue and depression were significantly higher at T5 than at T1 in two groups. Fatigue and depression increased in both the experimental and control groups’ patients over the five days of hospitalization during which TACE and chemotherapy were administered. The experimental group had significantly less fatigue than the control group, with lower subscale scores on physical, psychosocial, daily, and overall fatigue. There were no differences between the groups on depression. At posttest, the experimental group experienced lower physical, psychosocial, daily, and overall fatigue than the control group. Acupressure can improve fatigue in HCC patients during treatment with TACE but did not alleviate depression. Discharge planning should include home care for management of fatigue and depression.

  16. Radioimmune localization of occult carcinoma

    International Nuclear Information System (INIS)

    Patients with a rising serum carcinoembryonic antigen level and no clinical or roentgenographic evidence of recurrent or metastatic cancer present a treatment dilemma. Eleven such patients, 10 with a previously treated colorectal carcinoma and 1 with a previously treated breast carcinoma, received an injection of the anticarcinoembryonic antigen monoclonal antibody ZCE-025 labeled with the radioisotope indium 111. Nuclear scintigraphy was performed on days 3 and 5 through 7 to detect potential sites of tumor recurrence. The monoclonal antibody scan accurately predicted the presence or absence of occult malignancy in 7 (64%) patients. Second-look laparotomy confirmed the monoclonal antibody scan results in the patients with colorectal cancer, and magnetic resonance imaging confirmed metastatic breast cancer. This study demonstrates that In-ZCE-025 can localize occult carcinoma and may assist the surgeon in facilitating the operative exploration. In-ZCE-025 assisted in the initiation of adjuvant therapy for the patient with breast cancer

    To compare the results of treatment performed with and without team practice in glottic laryngeal cancer patients, including local control rate and preservation of voice. Since April 1991, radiation oncologists, radiologists and otolaryngologists have worked in close collaboration to treat head and neck cancer patients in the Kurume University Hospital. Treatment results of a total of 419 patients with glottic cancer were compared with or without team practice. In group A (period, Jan 1978 to Mar 1991), 237 glottic laryngeal cancer patients were treated before team practice. In group B (period, Apr 1991 to Mar 1997), 182 patients were treated with team practice. All patients had histologically proven invasive squamous cell carcinoma. Follow-up period was at least 2 years. In group A, a laser was preferentially used for T1 lesions (T1a: 41 lesions, 52.6%, T1b: 7 lesions, 15.6%), and partial laryngectomy or total laryngectomy was preferentially used for T2 lesions (partial laryngectomy: 21 lesions, 30.9% and total laryngectomy: 10 lesions, 14.7%). On the other hand, in group B, 126 (81.8%) T1 and T2 lesions were treated with radical radiation with or without laser. Local control rate of T1 and T2 cancer improved significantly from 78.3% for group A patients to 91.2% for group B patients (p<0.01). Larynx preservation rate improved slightly from 88.6% to 95.0%. Five year cause-specific survival rate for all stage I to IV patients improved from 94.8% to 96.5%, but was not significant. Relapse-free survival rate improved significantly from group A to group B: from 75.1% to 87.4% (p<0.01). Team practice has effective results in improved local control and preservation of natural voice for patients with glottic carcinoma. (author)

    Transforming growth factor-β activated kinase 1 (TAK1) has been shown to play a crucial role in cell death, differentiation, and inflammation. Here, we live-imaged robust TAK1 activation in Lewis lung carcinoma 3LL cells implanted into the s.c. tissue of syngeneic C57BL/6 mice and treated with polyinosinic:polycytidylic acid (PolyI:C). First, we developed and characterized a Förster resonance energy transfer-based biosensor for TAK1 activity. The TAK1 biosensor, named Eevee-TAK1, responded to stress-inducing reagents such as anisomycin, tumor necrosis factor-α, and interleukin1-β. The anisomycin-induced increase in Förster resonance energy transfer was abolished by the TAK1 inhibitor (5z)-7-oxozeaenol. Activity of TAK1 in 3LL cells was markedly increased by PolyI:C in the presence of macrophages. 3LL cells expressing Eevee-TAK1 were implanted into mice and observed through imaging window by two-photon excitation microscopy. During the growth of tumor, the 3LL cells at the periphery of the tumor showed higher TAK1 activity than the 3LL cells located at the center of the tumor, suggesting that cells at the periphery of the tumor mass were under stronger stress. Injection of PolyI:C, which is known to induce regression of the implanted tumors, induced marked and homogenous TAK1 activation within the tumor tissues. The effect of PolyI:C faded within 4 days. These observations suggest that Eevee-TAK1 is a versatile tool to monitor cellular stress in cancer tissues. PMID:26931406

  1. Prevention of hepatocellular carcinoma.

    Science.gov (United States)

    Kew, Michael C

    2010-01-01

    Because of its frequency and grave prognosis, preventing hepatocellular carcinoma is an urgent priority. Prevention should be possible because environmental carcinogens-chronic hepatitis B and C virus infections, dietary exposure to aflatoxins, and iron overload-cause the great majority of these tumors. Chronic hepatitis B virus infection accounts for 55% of global hepatocellular carcinomas and 80% of those in the high-incidence Asia Pacific and sub-Saharan African regions. In these regions the infection that becomes chronic is predominantly acquired very early in life. A safe and effective vaccine against this virus is available and its universal inclusion in the immunization of infants has already resulted in a marked reduction of chronic infection and a 70% decrease in the occurrence of hepatocellular carcinoma in those immunized. Chronic hepatitis C virus infection is the major cause of hepatocellular carcinoma in industrialized countries. The infection is mainly acquired in adulthood and, until a vaccine becomes available, prevention will consist mainly of identifying, counselling, and treating chronically infected individuals, preventing spread of the virus by the use of safe injection practices (particularly in intravenous drug abusers), and screening all donated blood for the presence of the virus. 4.5 billion of the world.s population are exposed to dietary aflatoxins. Prevention involves treating susceptible crops to prevent fungal contamination, and handling the foodstuffs in such a way as to prevent contamination during storage. Iron overload in hereditary hemochromatosis can be prevented by repeated venesection and in African dietary iron overload by fermenting the home-brewed beer in iron-free containers. PMID:20526004

    In this study, immunotoxin (IT) was prepared by conjugating BAC5 and CT with SPDP. The effects of IT on NPC and its mechanisms were explored using double labeled with radioactive nuclides, immunography and electron microscope technique in vivo and in vitro. The specific concentration of BAC5 in the tumor area showed. The radioactivity rate of tumor/nontumor (T/NT) was up to 10.26. IT had cytotoxic effects both on the cultured CNE-2 cell line and tumor multicell spheroides. In vivo, the preliminary result indicated that IT also had a inhibitory action on the nude mice models bearing human NPC (Reported in another article). Under electron microscope, the necrosis and apoptosis of tumor cells were found. The membranes of most tumor cells were found intacted not or corrosined, some of them had the character of apoptosis, including reduce of tumor cells membrane villi, condensation of cytoplasm and pyknosis or cleavage of nuclear. There were many of apoptosis bodies, which were occasionally phagocytosed by tumor cells. The infiltration of immunocytoes in tumor tissue could be seen. The results indicated that BAC5 can specifically combine with NPC cells and BAC5-CT has the inhibitory effect on NPC in vitro and in vivo, mechanism of which may be related to the effects that ‘warhead' CT dissolute the membrane of tumor cells directly, or/and IT promote the infiltration of immunocytoes so as to induce the apoptosis of tumor cell.

    The survival of patients with superior sulcus lung carcinoma and the effects of treatment were reviewed. From a prospective database of 4123 consecutive new patients with lung carcinoma, 131 (3.2%) cases of superior sulcus lung carcinoma were identified. Seventy-four patients were planned to receive radiation with palliative intent, 53 radical radiotherapy and one was observed only. The remaining three patients, with small-cell carcinoma, were treated with chemotherapy with or without radiotherapy. Of the 53 radically treated patients, nine were treated with pre-operative radiation prior to intended radical resection. Analysis was carried out on the effect on survival of performance status, nodal involvement, weight loss, vertebral body or rib involvement, treatment intent and radical combined modality treatment compared with radical radiation alone. The estimated median survival for the whole group was 7.6 months; for those treated radically it was 18.3 months, while for the palliatively treated patients it was 3.7 months. Radically treated patients with no initial nodal involvement had an estimated median survival of 22 months, while radically treated patients with nodal involvement had an estimated median survival of 8.4 months (P = 0.003). There were no statistically significant differences in survival between radically treated patients grouped according to initial weight loss, performance status, or vertebral body and rib involvement. Patients treated with pre-operative radiation did not survive significantly longer than patients treated with radiation alone, although the numbers are small. 33 refs., 2 tabs., 4 figs.

    Six patients with carcinoma of the vulva and 3 with carcinoma of the vagina following radiation therapy for cancer of the cervix were analyzed. The interval between irradiation and diagnosis of the second tumor varied from 5 to 23 years. Despite the lack of having detailed information on irradiation factors in all patients, circumstantial evidence from this study suggests that radiation therapy may have contributed to the development of carcinoma of the vulva and vagina in some of the patients. Close follow-up patients treated for squamous carcinoma of the genital tract must emphasize inspection for new lesions. The incidences previously reported in the literature are also reviewed for comparison. (author).

Close follow-up patients treated for squamous carcinoma of the genital tract must emphasize inspection for new lesions. The incidences previously reported in the literature are also reviewed for comparison. (author)

    International Nuclear Information System (INIS)

    96 women with primary carcinoma corporis uteri and 79 women after surgery were treated between 1965 - 1970 with different radiotherapeutic methods, in some cases in combination with cytostatics and gestagens. In the group of primary radiation best results were obtained with combination of intracavitary brachytherapy and external radiation (55% 5-years-survival), and in the postoperative group with external radiation alone (67% 5-years-survival). Late complications with 17% fibrosis in the parametrial tissue and 12% persistant diarrhea in the postoperative group needs strict individualization in therapy and requires exact knowledge on extention and biological behavior of the tumor.

  11. Higher Biologically Effective Dose of Radiotherapy Is Associated With Improved Outcomes for Locally Advanced Non–Small Cell Lung Carcinoma Treated With Chemoradiation: An Analysis of the Radiation Therapy Oncology Group

    International Nuclear Information System (INIS)

    Purpose: Patients treated with chemoradiotherapy for locally advanced non–small-cell lung carcinoma (LA-NSCLC) were analyzed for local-regional failure (LRF) and overall survival (OS) with respect to radiotherapy dose intensity. Methods and Materials: This study combined data from seven Radiation Therapy Oncology Group (RTOG) trials in which chemoradiotherapy was used for LA-NSCLC: RTOG 88-08 (chemoradiation arm only), 90-15, 91-06, 92-04, 93-09 (nonoperative arm only), 94-10, and 98-01. The radiotherapeutic biologically effective dose (BED) received by each individual patient was calculated, as was the overall treatment time-adjusted BED (tBED) using standard formulae. Heterogeneity testing was done with chi-squared statistics, and weighted pooled hazard ratio estimates were used. Cox and Fine and Gray’s proportional hazard models were used for OS and LRF, respectively, to test the associations between BED and tBED adjusted for other covariates. Results: A total of 1,356 patients were analyzed for BED (1,348 for tBED). The 2-year and 5-year OS rates were 38% and 15%, respectively. The 2-year and 5-year LRF rates were 46% and 52%, respectively. The BED (and tBED) were highly significantly associated with both OS and LRF, with or without adjustment for other covariates on multivariate analysis (p < 0.0001). A 1-Gy BED increase in radiotherapy dose intensity was statistically significantly associated with approximately 4% relative improvement in survival; this is another way of expressing the finding that the pool-adjusted hazard ratio for survival as a function of BED was 0.96. Similarly, a 1-Gy tBED increase in radiotherapy dose intensity was statistically significantly associated with approximately 3% relative improvement in local-regional control; this is another way of expressing the finding that the pool-adjusted hazard ratio as a function of tBED was 0.97. Conclusions: Higher radiotherapy dose intensity is associated with improved local-regional control

    Full Text Available Abstract Background Several parameters of the tumor microenvironment, such as hypoxia, inflammation and angiogenesis, play a critical role in tumor aggressiveness and treatment response. A major question remains if these markers can be used to stratify patients to certain treatment protocols. The purpose of this study was to investigate the inter-relationship and the prognostic significance of several biological and clinicopathological parameters in patients with head and neck squamous cell carcinoma (HNSCC treated by radiotherapy ± chemotherapy. Methods We used two subgroups of a retrospective series for which CT-determined tumoral perfusion correlated with local control. In the first subgroup (n = 67, immunohistochemistry for carbonic anhydrase IX (CA IX and glucose transporter-1 (GLUT-1 was performed on the pretreatment tumor biopsy. In the second subgroup (n = 34, enzyme linked immunosorbent assay (ELISA was used to determine pretreatment levels of the cytokines vascular endothelial growth factor (VEGF and interleukin-6 (IL-6 in serum. Correlation was investigated between tumoral perfusion and each of these biological markers, as well as between the markers mutually. The prognostic value of these microenvironmental parameters was also evaluated. Results For CA IX and GLUT-1, the combined assessment of patients with both markers expressed above the median showed an independent correlation with local control (p = 0.02 and disease-free survival (p = 0.04 with a trend for regional control (p = 0.06. In the second subgroup, IL-6 pretreatment serum level above the median was the only independent predictor of local control (p = 0.009, disease-free survival (p = 0.02 and overall survival (p = 0.005. Conclusion To our knowledge, we are the first to report a link in HNSCC between IL-6 pretreatment serum levels and radioresistance in vivo. This link is supported by the strong prognostic association of pretreatment IL-6 with local control, known to be

    Objective To evaluate the predictive values of different systems for clinical staging of esophageal carcinoma in one group of patients and improve the criteria for T staging,and to provide a basis for accurate clinical staging. Methods A retrospective study was performed in 701 patients with esophageal carcinoma who received radical radiotherapy in our hospital. The prognosis was performed according to American Joint Committee on Cancer ( AJCC) tumor-node-metastasis staging system,Chinese 2004 staging system,the draft of Chinese 2009 staging system,and gross tumor volume of the primary tumor (GTV-T). Results In terms of T stage,patients evaluated according to the AJCC staging system were in relatively early stages;23. 1% of them were in stage T1,and the survival curves of T3 and T4 patients were close to each other;the survival curves plotted according to the Chinese 2004 staging system were well separated, but relatively few patients were in stages T1 and T4 , yielding an uneven distribution;according to the draft of Chinese 2009 staging system, the survival curve of T3 patients intersected that of T4 patients, and up to 43. 2% of patients were in stage T4.The new T staging was performed based on GTV and the extent of tumor invasion into the adjacent tissue and organ, and the results showed that there was no intersection between survival curves and a relatively balanced T stage distribution. In terms of N staging,patients were divided into stages N0 ,N1 ,and N2 . The TNM staging was performed by a combination of N staging and new T staging, resulting in significant separation between survival curves ( P=0. 000) . Conclusions The combination of T staging,which is based on GTV and the extent of tumor invasion,and N staging,which is based on metastasis of lymph nodes, can accurately predict the survival of non-surgically treated patients with esophageal carcinoma.%目的 比较不同食管癌临床分期对同一组病例的预测价值,并完善T分期标准,为更

  15. Thermoradiotherapy for colorectal carcinoma

    International Nuclear Information System (INIS)

    The Japanese Society for Therapeutic Radiology and Oncology conducted a survey of the present state of thermoradiotherapy for colorectal carcinomas in Japan. In this survey, 105 cases at the 9 institutions were registered which had been treated from January 1981 to December 1992. From this data, we analyzed the trend of hyperthermia for the colorectal carcinoma and the treatment parameters which might have an influence on the treatment results. Ninety-four of 105 cases were recurrent or metastatic lesions. Mainly, the RF capacitive heating equipment was applied for the colorectal carcinoma. The number of cases in which hyperthermia were given once or twice a week were almost equal, and there was no significant difference in the treatment response rate. The mean duration of hyperthermia at therapeutic temperature was 42 min. Measurements of temperature in lesions were performed in 86% of sessions, and the mean tumor temperature was 43.1degC. Higher maximum tumor temperature and longer treatment time have brought significantly better response. Responder groups have shown better survival than non-responder groups. Acute reactions associated with hyperthermia were as follows: pain in 35 cases, burn and/or skin erosion in 12 cases, abscess formation in 3 cases and others in 3 cases. Late effects of treatment were ileus in 9 cases, ulcer of intestinal tract in 5 cases, subcutaneous fibrosis in 3 and others in 6. In conclusion, the application of thermoradiotherapy for reflactory colorectal carcinoma may contribute to the improvement of prognosis and quality of life of patients. (author)

    Full Text Available Purpose: To describe a series of patients with Non-Hodgkin′s lymphoma (NHL and concomitant eyelid carcinoma. Methods: In this non-comparative interventional case series, we retrospectively reviewed the medical records of 5 patients with NHL who developed eyelid carcinoma. Results: The patients included one female and four male subjects. Systemic lymphoma had been diagnosed 1 to 72 months prior to development of the eyelid carcinoma. The lesions were basal cell carcinoma in three, and squamous cell carcinoma in two cases. The lymphoma was advanced (stage III or IV in all patients. Four patients underwent surgical excision of the carcinoma and one patient was awaiting surgical treatment after completing systemic chemotherapy. Three subjects had high-grade carcinomas. Two patients had perineural invasion; one received adjuvant radiotherapy postoperatively but the other did not due to receiving systemic chemotherapy for recurrent NHL. Conclusions: Systemic lymphoma may be associated with aggressive eyelid carcinomas. Perineural invasion is frequently encountered in this situation and should be treated with adjuvant radiation therapy to decrease the likelihood of local recurrence.

    Pre-operative staging, using transrectal prostatic sonography and CT, was carried out in 30 patients with cytologically confirmed carcinomas of the prostate and the results compared with the clinical findings. All patients underwent radical prostatectomy and the pre-operative findings could be verified histologically. Transrectal prostatic sonography is better than CT or clinical examination for determining local tumour spread or penetration of the capsule. A high proportion of enlarged pelvic lymphnodes shown by CT had non-specific changes; failure to demonstrate enlarged nodes excludes lymph node metastases with considerable certainty. Transrectal prostatic sonography provides a higher degree of information regarding local tumour spread, whereas CT indicates the presence or absence of lymph node metastases. (orig.)

    Objective: To study the mechanism, clinical characteristics, therapy regimens, and survival of cervical carcinoma metastases to the brain. Methods: We retrospectively analyzed 11 patients with brain metastases from cervical carcinoma. Results: Two cases were at stage lb, two at IIa, and seven at IIIb, respectively. Histologically, they were squamous cell carcinoma (6 cases), adeno-squamous carcinoma (2 cases), small cell carcinoma (2 cases), or adenocarcinoma (1 cases), poorly differentiated. Eight were accompanied with lung, liver, and bone metastases disease and three had no any other systemic metastases at the time of the brain metastases diagnosis. Two had controlled, and other nine were uncontrolled or progressive primary disease. The median interval from the diagnosis of the primary carcinoma to the detection of brain lesion was 14.6 months. Headache was the most common symptom of brain metastases. Eight of 11 patients developed multiple lesions and other 3 cases had a solitary lesion in brain. The patients were treated by combination of surgery and whole brain radiation therapy (WBRT) (3 cases), stereotactic radiosurgery (SRS) (3 cases), or WBRT (5 cases). The patients had a median survival of 6.6 months. Conclusion: Brain metastases are not always a late complication of cervical carcinoma. The development of the metastases is related to pathological type, poorly differentiation, and advanced stage. Surgery and SRS arc the appropriate therapy regimen for these patients.

    Full Text Available Purpose: We aimed to externally validate the association of 2- and 3-year disease-free survival with 5-year overall survival in patients treated with radical cystectomy for urothelial carcinoma of the bladder. Materials and Methods: We reviewed the clinical data of 422 patients who underwent radical cystectomy for urothelial carcinoma of the bladder in our institution between 1991 and 2012. Survival curves were plotted with the Kaplan–Meier method. The Kappa statistic and Kendall tau-b test were used to assess the agreements between 2- and 3-year disease free survival and 5-year overall survival. Results: In the entire study population, 2- and 3-year disease free and 5-year overall survival rates were 76.4%, 71.5%, and 67.4%, respectively. All Kappa and Kendall’s tau-b test values for agreements between 2- and 3-year disease free and 5-year overall survival were more than 0.40, indicating moderate agreement for all patients and in each patient subgroup selected according to specific variables (all p values <0.05. Kaplan–Meier analysis for disease free survival and Cox-proportional hazard models for landmark analysis at each time point indicated that most recurrences occurred within 3 years after surgery. The 5-year overall survival rates of patients who were recurrence free at each time point gradually increased to more than 95% in an extended recurrence-free interval of 12–36 months.Conclusions: Our external validation results support the existing finding that 2- and 3-year disease free survival can be a valid early surrogate end point to predict 5-year overall survival after radical cystectomy in patients with urothelial carcinoma of the bladder.

    Full Text Available Although historically thymoma and thymic carcinoma have been treated surgically, radiation therapy also has an important role, either as postoperative therapy to reduce the risk of mediastinal recurrence or as part of definitive treatment for patients who cannot undergo surgery. Induction chemotherapy and molecular targeted agents may also be appropriate for thymic carcinoma, the behavior of which resembles non-small cell lung carcinoma more than that of thymoma or invasive thymoma and is increasingly being treated like lung cancer. We present here a review of current therapies for thymic malignancies and briefly discuss the potential benefits from novel technologies for such treatment.

    Full Text Available It is well known that the prognosis of pancreatic cancer is extremely poor, even when treated with radical surgery. The overall 5 year survival rate following surgical intervention is around 10%.With the increasing use of CT scans for other reasons not related to pancreas, a variety of neoplastic and non - neoplastic lesions are increasingly encountered in clinical practice. The distinction of these lesions has significant therapeutic and prognostic implications. Regarding ductal carcinoma, key distinguishing features from chronic pancreatitis and a discussion of the concept of pancreatic intraepithelial neoplasia ( PanIN are included. Precursors, mo lecular carcinogenesis, risk factors and different morphological patterns of tumors arising from exocrine pancreas are discussed. Research on early detection is ongoing. Screening of people with a family history of hereditary pancreatitis plays an importan t role in the early detection of ductal carcinoma of pancreas.

    The incidence of hepatocellular carcinoma (HCC) appears to be declining in Taiwan and potentially in other high-prevalence areas as a consequence of vaccination for hepatitis B virus (HBV). However, there is evidence that the incidence of HCC is increasing in North America and Europe. This appears to be related to the increasing prevalence and duration of hepatitis C virus (HCV) infection in these countries. There is also growing evidence to support an increase in the risk of HCC in patients with HCV who are coinfected with occult HBV (patients who have lost HBV surface antigen but still have detectable HBV DNA either in blood or liver). Occult HBV infection in patients with HCV may be more common than previously thought, and HCC that occurs in this setting appears to have a worse prognosis. There is continuing interest in the effect of interferon therapy on the incidence of HCC in patients with HCV. Several studies from Japan have shown a benefit in patients without cirrhosis, although there are a number of potentially confounding variables that may partly explain these results. Prospective randomized studies are needed to investigate this important question. The molecular biology of HCC and the events of malignant transformation in the liver continue to be areas of intense study. Recently, there has been considerable interest in telomeres, the repeat units on the ends of chromosomes, and the enzyme that maintains these, telomerase. Telomeres shorten with each cell division and can be used to determine the number of divisions a cell has undergone. Eventually they reach a critical length, with further loss resulting in cellular senescence. Telomerase restores telomere length and may help malignant cells escape senescence. Nearly all HCCs have telomerase activity and assessments of telomeres and telomerase may be clinically useful. PMID:17023886

    Full Text Available IntroductionHepatocellular carcinoma (HCC is one of the most common malignant tumors worldwide(1, with over four hundred thousand new cases and almost as many deaths each year(2. The incidence ranges from <10 cases per 100,000 population in North America and Western Europe to 50-150 cases per 100,000 population in parts of Africa and Asia where HCC is responsible for a large proportion of cancer deaths. Studies from the USA, UK, mainland Europe and Australia have shown a rising incidence of HCC(3-6, which probably relates to the increasing prevalence of hepatitis B and C due to immigration(7. Improved care for individuals with cirrhosis has resulted in prolonged and a relatively greater opportunity for malignant changes to develop. HCC is a disease of multifactorial etiology; the development of a carcinoma in a given individual is a multi-step process and the result of an accumulation of risks. It is estimated that persistent infection with hepatotrophic viruses account for well over 80% of the world's liver cancer(8. Hepatocellular carcinoma is the major cause of death in cirrhotic patients in Europe(9,10,11. Once cirrhosis is present, up to 20% of patients will develop HCC over 10 years(12. Genetic alterations are fundamental to the development of HCC by resulting in uncontrolled cellular proliferation and de-differentiation. Without treatment, the prognosis is dismal, with only a few months survival(13. Several surgical and non-surgical therapeutic modalities have been used for the treatment of HCC. Surgical resection, liver transplantation and local ablation therapies demonstrate potentially curative treatment options that should always be considered when the tumor is restricted to liver.EpidemiologyThe incidence of HCC varies widely by geographic location. The distribution of HCC also differs among ethnic groups and regions within the same country(14. High incidence regions (more than 15 cases per 100,000 populations per year include sub

    Case: A 63-year-old male presented with unintentional weight loss of 20 pounds over a 4-month duration. 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. The patient will receive palliative systemic therapy

    Hepatocellular carcinoma (HCC) is increasing in many countries as a result of an increase in hepatitis C virus (HCV) infection since World War II. The epidemiology of HCC varies with the global region. There have been conflicting observations from different parts of the world concerning the frequency of HCC in patients who in the distant past had post-transfusion non-A, non-B hepatitis. The genetic basis of hepatocarcinogenesis is still poorly understood. In hepatitis B virus (HVB) associated HCC, codon 249 mutation in the p 53 gene seems more related to exposure to aflatoxin B1 than to hepatocarcinogenesis itself. HCC that occurs in children in high HBV endemic regions could be associated with germ-line mutations, but little information is available; not much is known about chemical hepatocarcinogens in the environment other than aflatoxins. The X gene of HBV seems to play an important role in HBV-associated hepatocarcinogenesis. There are preliminary observations on the molecular mechanism of HCV-associated HCC, such as HCV core protein inducing HCC in transgenic mice and the NS3 genome transforming NIH 3T3 cells. Pathological distinction between preneoplastic and very early transformed lesions still depends on classical morphology, and a more genetically oriented differential diagnosis is required. Clinical diagnosis based on modern imaging has improved greatly, but is still unsatisfactory in the differential diagnosis of preneoplastic and early transformed nodules, because the vasculature changes that occur within the nodule are not accurately discerned with the current imaging. Use of sensitive des-gamma-carboxy prothrombin (PIVKA II) assay, and lectin affinity chromatography separating HCC specific subspecies of AFP molecules with a more practical biochemical technique will further improve diagnosis. Early diagnosis and transplantation are the best treatment at the moment, but transplantation is not widely available because of the donor shortage. Despite

  10. Team practice for laryngeal carcinoma. 1. Supraglottic carcinoma

    International Nuclear Information System (INIS)

    To compare results of treatment performed (a) with and (b) without team practice in supraglottic laryngeal cancer patients, including local control rate and preservation of voice. In April 1991, the first author joined the Kurume University hospital. Since then, radiation oncologists, radiologists and otolaryngologists have worked in close collaboration to treat head and neck cancer patients. We examined all cancer patients together and discussed and determined the choice of treatment modalities as a team. In group A (period, Jan. 1978 to Mar. 1991), 125 supraglottic laryngeal cancer patients were treated before team practice. Among them, only 6 (9.1%) T1 and T2 patients were treated with radical radiotherapy. In group B (period, Apr. 1991 to Mar. 1997), 74 patients were treated with team practice, of which 22 (73.3%) T1 and T2 patients were treated with radical radiation. All 199 patients had histologically proven invasive squamous cell carcinoma. Follow-up period was at least 2 years. Local control rate of T1 and T2 cancer improved from 75.3% for group A patients to 87.7% for group B patients. Larynx preservation rate improved significantly from 49.4% to 85.6% (P<0.01). Five-year overall, cause-specific and relapse-free survival rate for all stages I to IV patients improved significantly from group A to group B: from 52.8% to 68.8%, from 67.0% to 86.1% and from 51.7% to 81.2%, respectively. Team practice provides effective results in improved local control and preservation of natural voice for patients with supraglottic carcinoma. (author)

    A 36-year-old woman with nasopharyngeal carcinoma developed radiation myelopathy. She was treated with radiotherapy, a total dose of about 120 Gy to the cervical spinal cord at the C1 level, chemotherapy and immunotherapy. Nine months after the final radiation therapy, she complained of a paresthesia in the distal area of the right leg. Neurological examination revealed incomplete left Brown-Sequard syndrome below the level of C5. Neurological symptoms had been progressive. The spinal MRI showed an abnormal intramedullary high intensity area enhanced by Gd-DTPA. (author).

  12. The influence of young age and positive family history of breast cancer on the prognosis of ductal carcinoma in situ treated by excision with or without radiation therapy or by mastectomy

    International Nuclear Information System (INIS)

    Background: Several recent studies have investigated the influence of family history on the progression of DCIS patients treated by tylectomy and radiation therapy. Since three treatment strategies have been used for DCIS at our institution, we evaluated the influence of family history and young age on outcome by treatment method. Methods: Between 1/1/82 and 12/31/92, 128 patients were treated for DCIS by mastectomy (n = 50, 39%), tylectomy alone (n = 43, 34%), and tylectomy with radiation therapy (n = 35, 27%). Median follow-up is 8.7 years. Thirty-nine patients had a positive family history of breast cancer; 26 in a mother, sister, or daughter (first-degree relative); and 26 in a grandmother, aunt, or cousin (second-degree relative). Thirteen patients had a positive family history in both first- and second-degree relatives. Results: Six women developed a recurrence in the treated breast; all of these were initially treated with tylectomy alone. There were no recurrences in the mastectomy group or the tylectomy patients treated with postoperative radiation therapy. Patients with a positive family history had a 10.3% local recurrence rate (LRR), vs. a 2.3% LRR in patients with a negative family history (p = 0.05). Four of 44 patients (9.1%) 50 years of age or younger recurred, compared to two of 84 patients (2.4%) over the age of 50 (p = 0.10). Fifteen patients had both a positive family history and were 50 years of age or younger. Among these women, the recurrence rate was 20%. Women in this group treated by lesionectomy alone had a LRR of 38% (3 of 8). Conclusion: The most important determinant of outcome was the selection of treatment modality, with all of the recurrences occurring in the tylectomy alone group. In addition to treatment method, a positive family history significantly influenced LRR in patients treated by tylectomy, especially in women 50 years of age or younger. These results suggest that DCIS patients, particularly premenopausal women with a

    Full Text Available Temozolomide is an alkylating agent used in the treatment of gliomas and, more recently, aggressive pituitary adenomas and carcinomas. Temozolomide methylates DNA and, thereby, has antitumor effects. O6-methylguanine-DNA methyltransferase, a DNA repair enzyme, removes the alkylating adducts that are induced by temozolomide, thereby counteracting its effects. A Medline search for all of the available publications regarding the use of temozolomide for the treatment of pituitary tumors was performed. To date, 46 cases of adenohypophysial tumors that were treated with temozolomide, including 30 adenomas and 16 carcinomas, have been reported. Eighteen of the 30 (60% adenomas and 11 of the 16 (69% carcinomas responded favorably to treatment. One patient with multiple endocrine neoplasia type 1 and an aggressive prolactin-producing adenoma was also treated and demonstrated a good response. No significant complications have been attributed to temozolomide therapy. Thus, temozolomide is an effective treatment for the majority of aggressive adenomas and carcinomas. Evidence indicates that there is an inverse correlation between levels of O6-methylguanine-DNA methyltransferase immunoexpression and therapeutic response. Alternatively, high-level O6-methylguanine-DNA methyltransferase immunoexpression correlates with an unfavorable response. Here, we review the use of temozolomide for treating pituitary neoplasms.

    Six hundred and nine cases of invasive squamous cell carcinoma of the cervix uteri in a retrospective analysis (1953-1982) at the A.C. Camargo Hospital, Antonio Prudente Foundation, Sao Paulo, Brazil. The patients were submitted to radical surgery and radiation therapy, individually or in combination. A multivariate analysis of the different variables were performed according to the Cox`s regression method. The variables of prognosis value, in decreasing order of importance, were: the decade of patient`s admission, the modality of therapy employed, the presence of residual tumor in the surgical specimens and the clinical stage of the disease. Other variables like ethnic group, age of first menstrual flux, menopause, number of pregnancy, kind of delivery, number and kind of abortion, were found to be of no prognostic importance. The decade of admission was of independent prognostic significance. The presence of residual tumor in the surgical specimens was more important than lymph nodes spreading, but the overall survival was affected by the increase in the number of positive lymph nodes. Patient`s age was a weak prognostic factor accounting for a reduction in the survival time among cases with age upper to 45 years old. Radiation therapy sterilizes a considerable number of lymph nodes but not all of them in every patient. There are a specific group of patients where the radical surgery is necessary in order to carry a complete debulking of the disease. (author) 82 refs., 10 figs.

    AIM: To investigate the poor prognosis of HCC with PVTT, we evaluated the efficacy by a new combination chemotherapy for advanced hepatocellular carcinoma (HCC) with portal vein tumor thrombus (PVTT).METHODS: From 2002 to 2007, a total of 10 consecutive patients with Stage IVA HCC accompanied by PVTT were studied prospectively to examine the efficacy of treatment by intra-arterial infusion of a chemotherapeutic agents consisting of etoposide, carboplatin, epirubicin and pharmacokinetic modulating chemotherapy by 5-FU and enteric-coated tegafur/uracil.RESULTS: The mean course of chemotherapy was 14.4 (range, 9-21) mo. One patient showed complete response (CR) with disappearance of HCC and PVTT after treatment, and the two patients showed partialresponse (PR), response rate (CR + PR/All cases 30%).The median survival time after the therapy was 457.2 d. The one-year survival rate was 70%. Adverse reactions were tolerable.CONCLUSION: Although the prognosis of most patients with Stage IVA HCC by PVTT is poor, our combination chemotherapy may induces long-term survival and is an effective treatment and produced anti-tumor activity with tolerable adverse effects in patients for advanced Stage IVA HCC accompanied by PVTT.

    This study examined the biological and clinical significance of NAC1 (nucleus accumbens associated 1) expression in both cervical squamous cell carcinomas and adenocarcinomas/adenosquamous carcinomas. Using immunohistochemistry, the frequency of positive NAC1 expression in adenocarcinomas/adenosquamous carcinomas (31.0%; 18/58) was significantly higher than that in squamous cell carcinomas (16.2%; 12/74) (P = .043). NAC1 gene amplification was identified by fluorescence in situ hybridization in 5 (7.2%) of 69 squamous cell carcinomas. NAC1 amplification was not identified in the adenocarcinomas (0%; 0/58). Positive NAC1 expression was significantly correlated with shorter overall survival in squamous cell carcinomas (P NAC1 expression in squamous cell carcinomas was an independent prognostic factor for overall survival after standard radiotherapy (P = .0003). In contrast to squamous cell carcinomas, positive NAC1 expression did not correlate with shorter overall survival in adenocarcinomas/adenosquamous carcinomas (P = .317). Profound growth inhibition, increased apoptosis, decreased cell proliferation, and decreased cell migration and invasion were observed in silencing RNA-treated cancer cells with NAC1 overexpression compared with cancer cells without NAC1 expression. NAC1 overexpression stimulated proliferation, migration, and invasion in the cervical cancer cell lines TCS and Hela P3, which normally lack NAC1 expression. These findings indicate that NAC1 overexpression is critical to the growth and survival of cervical carcinomas irrespective of histologic type. Furthermore, they suggest that NAC1 silencing RNA-induced phenotypes depend on the expression status of the targeted cell line. Therefore, cervical carcinoma patients with NAC1 expression may benefit from a targeted therapy irrespective of histologic type.

    UNLABELLED: Gastric neuroendocrine carcinomas (NECs) are rare tumours that are divided into four subtypes depending on tumour characteristics. Patients with NECs are known to have an increased risk of synchronous and metachronous cancers mainly located in the gastrointestinal tract. A case...... of synchronous gastric NEC and hepatocellular carcinoma in a patient with several other precancerous lesions is presented. The patient had anaemia, and a gastric tumour and two duodenal polyps were identified on upper endoscopy. A CT scan of the abdomen revealed several lesions in the liver. The lesions were...... invisible on B-mode sonography and real-time sonography fused with CT was used to identify and biopsy one of the lesions. Histology showed hepatocellular carcinoma. A literature search showed that only one case of a hepatocellular carcinoma synchronous with a gastric NEC has been reported previously. TRIAL...

    Objective: To investigate the clinicopathologic features and diagnostic criteria of urachal carcinoma in the bladder.Methods: Seven cases of urachal carcinoma in the bladder were analyzed retrospectively. Results: All the tumors were found locating in the dome of bladder. Of them, 4 were mucinous adenocarcinoma, one was well differentiated papillary enteric adenocarcinoma, one was well differentiated squamous carcinoma, and one was neuroendocrine carcinoma. Cystomorphous urachal remnants were found in 4 cases. The main complaint was hematuria and all patients underwent partial excision of bladder and urachus. Conclusion: Mucinous adenocarcinoma is the main histo-pathological type, and cystomorphous urachal remnants are often accompanied with urachal carcinoma in the bladder. The key diagnostic criteria of urachal carcinoma in bladder are site and histopathology. And to examine the specimens carefully to find the urachal remnants is important.

    @@ Introduction Carcinomas of the stomach are the most common malignant tumors in China. Due to the recent developments in diagnostic techniques and instrumentation, the early detection of gastric carcinoma (GC) has increased. Yet synchronous multiple primary gastric carcinomas, de-fined as 2 or more primary gastric carcinomas occurring in 1 patient simultaneously, are not frequently seen. The etiology of synchronous tumors is still unclear, and their coexistence can be problematic for surgeons, oncologists and pathologists in regards to diagnosis, treat-ment, and follow-up. Research has focused mainly on such issues as the frequency of occurrence of primary multiple carcinomas, identi-fication of high-risk groups, early diagnosis, treatment methods, and prognostic factors. The purpose of this article is to present a rare case of synchronous tumors and to review the literature addressing the sur-gical treatment for patients with multiple cancers.

    Parathyroid carcinoma is a rare endocrine malignancy accounting for 0.5% to 4.0% of all cases of hyperparathyroidism and commonly present as hypercalcemia and parathyroid hormone (PTH) elevation. Nonfunctional parathyroid carcinoma does not show symptoms of hyperparathyroidism and only showed a vague indication of being pathologic, even when detected late. The optimal treatment is en bloc resection of the cancer, but frequent local recurrence after surgery has been reported. Adjuvant local treatment such as radiotherapy may improve the likelihood local control in cases with incompletely resected or microscopic residual tumor. The results of this study point to a case of nonfunctional parathyroid carcinoma treated by external beam radiotherapy after en-bloc resection of cancer.

    The objective of this study was to comprehensively evaluate the clinical outcomes of 110 consecutive Japanese patients who received at least two cycles of sunitinib as first-line therapy for metastatic renal cell carcinoma (mRCC) in a routine clinical setting. Initially, 50 mg of sunitinib was administered once daily on a 4 weeks on, followed by 2 weeks off dosing schedule; however, dose modification was required in 102 patients, and the relative dose intensity was 62.6 % throughout this series. As the best responses to sunitinib, 2, 28, 65 and 15 were judged to show a complete response, partial response, stable disease and progressive disease, respectively. The median progression-free survival (PFS) and overall survival (OS) following the treatment with sunitinib were 7.8 and 33.2 months, respectively. Multivariate analyses of several factors identified the following independent predictors of PFS and OS: Memorial Sloan Kettering Cancer Center (MSKCC) classification and C-reactive protein (CRP) level for PFS and liver metastasis, MSKCC classification and CRP level for OS. The common adverse events related to sunitinib corresponding to ≥grade 3 were thrombocytopenia in 59, leukopenia in 23, fatigue in 22, hand-foot syndrome in 15 and hypertension in 12. Quality of life (QOL) analysis using 36-Item Short Form revealed no significant differences in any scale scores between surveys performed before and 3 months after the treatment with sunitinib. Collectively, these findings suggest that the introduction of sunitinib as a first-line agent can lead to favorable disease control with acceptable tolerability, resulting in improvement in the prognosis and QOL of Japanese patients with mRCC.

    Purpose: To propose a lymph node (N) staging system for nasopharyngeal carcinoma (NPC) based on the International Consensus Guidelines for lymph node (LN) levels and MRI-determined nodal variables. Methods and Materials: The MRI scans and medical records of 749 NPC patients receiving intensity modulated radiation therapy with or without chemotherapy were retrospectively reviewed. The prognostic significance of nodal level, laterality, maximal axial diameter, extracapsular spread, necrosis, and Union for International Cancer Control/American Joint Committee on Cancer (UICC/AJCC) size criteria were analyzed. Results: Nodal level and laterality were the only independent prognostic factors for distant failure and disease failure in multivariate analysis. Compared with unilateral levels Ib, II, III, and/or Va involvement (hazard ratio [HR] 1), retropharyngeal lymph node involvement alone had a similar prognostic value (HR 0.71; 95% confidence interval [CI] 0.43-1.17; P=.17), whereas bilateral levels Ib, II, III, and/or Va involvement (HR 1.65; 95% CI 1.06-2.58; P=.03) and levels IV, Vb, and/or supraclavicular fossa involvement (HR 3.47; 95% CI 1.92-6.29; P<.01) both significantly increased the HR for distant failure. Thus we propose that the N category criteria could be revised as follows: N0, no regional LN metastasis; N1, retropharyngeal lymph node involvement, and/or unilateral levels Ib, II, III, and/or Va involvement; N2, bilateral levels Ib, II, III, and/or Va involvement; N3, levels IV, Vb, and/or supraclavicular fossa involvement. Compared with the 7th edition of the UICC/AJCC criteria, the proposed N staging system provides a more satisfactory distinction between the HRs for regional failure, distant failure, and disease failure in each N category. Conclusions: The proposed N staging system defined by the International Consensus Guidelines and laterality is predictive and practical. However, because of no measurements of the maximal nodal diameter on MRI slices

Methods: Between June 2012 and December 2013, 40 EC patients undergoing chemoradiotherapy were divided into the NST group and routine treatment (RT) group, with 20 patients in each group. At the end of chemoradiotherapy, the nutritional status, incidence of complications, and completion rates of radiotherapy were evaluated. The length of hospital stay (LOS) and cost were also compared between the two groups. Results:The nutrition and blood parameter values of the NST group were better (P0.05) for the patients of the NST group. Conclusion: NST could maintain the nutritional status and improve the treatment compliance and tolerance of EC patients undergoing chemoradiotherapy, thereby shortening the LOS time and reducing the costs.

    Full Text Available Abstract Background Collision tumors of the thyroid gland are a rare entity. We present a case of a follicular variant of papillary carcinoma and squamous carcinoma in the thyroid. To the best of our knowledge, this is the first documentation of a collision tumor with a papillary carcinoma and a squamous carcinoma within the thyroid gland. The clinicopathological features and immunohistochemical profile are reported. The theories of origin, epidemiology and management are discussed with a literature review. Case presentation A 65 year old woman presented with a large thyroid swelling of 10 years duration and with swellings on the back and scalp which were diagnosed to be a follicular variant of papillary thyroid carcinoma with metastasis. Clinical examination, radiology and endoscopy ruled out any other abnormality of the upper aerodigestive tract. The patient was treated surgically with a total thyroidectomy with central compartment clearance and bilateral selective neck dissections. The histopathology revealed a collision tumor with components of both a follicular variant of papillary carcinoma and a squamous carcinoma. Immunohistochemical analysis confirmed the independent origin of these two primary tumors. Adjuvant radio iodine therapy directed toward the follicular derived component of the thyroid tumor and external beam radiotherapy for the squamous component was planned. Conclusion Collision tumors of the thyroid gland pose a diagnostic as well as therapeutic challenge. Metastasis from distant organs and contiguous primary tumors should be excluded. The origins of squamous cancer in the thyroid gland must be established to support the true evolution of a collision tumor and to plan treatment. Treatment for collision tumors depends upon the combination of primary tumors involved and each component of the combination should be treated like an independent primary. The reporting of similar cases with longer follow-up will help define the

    114 patients with primary carcinoma of the vagina were treated in our hospital from 1958 to 1978. It accounted for 0.83% of all gynecological malignant tumors in the same period. The youngest was 26 years of age, the oldest 75. Patients 40-59 years comprised 61.4%. 33% of patients had wedding age under 17. 63.4% had more than 4 pregnancies and 58.4% gave more than 4 births. 89.69% was diagnosed as squamous cell carcinoma, 7.2% as adenocarcinoma, 2.06% as undifferentiated carcinoma and 1 as embryonic carcinoma. The tumor occurred frequently in the upper third and posterior wall of the vagina (60% and 68%). In this series, there were 21 stage I, 29 stage II, 61 stage III and 3 stage IV lesions. 110 patients were treated by radiotherapy in different schemes. Intracavitary radium or caesium plus 60Co external irradiation by four fields gave better result with a 5 year survival rate of 66.1%. Only 2 out of 12 patients were cured by 60Co rotation alone but if supplemented by intracavitary radium or caesium, the cure rate was increased. The 5 year survival rate was 71.4% for stage I, 62.1% for stage II, 42.6% for stage III and O for stage IV. After the radiotherapy, rectovaginal fistula developed in 1 patient, vesicovaginal fistula in 1. 14% was complicated with rectal bleeding and 8.18% with hematuria. PMID:3452544

    2012-01-01

    Background and purpose: Two clinical trials SHARP and ORIENTAL confirmed that sorafenib, a multi-kinase inhibitor could significantly improve PFS as well as TTP, and prolong OS for patients with hepatocellular carcinoma. Therefore sorafenib was approved to treat advanced hepatocellular carcinoma in 2008. Our study was designed to observe efficacy and adverse reactions of sorafenib alone or in combination with TACE in treating 30 patients with advanced hepatocellular carcinoma. Methods: From Mar 2009 to Jan 2011, a total of 30 patients with clinical or pathological diagnosis of advanced primary hepatocellular carcinoma orally took sorafenib with dosage of 400 mg each time, 2 times a day, and treatment duration was at least more than 2 months. Twenty patients received TACE for 1 to 9 times in combination with sorafenib, and 10 patients took sorafenib alone. In accordance with RESIST, efficacy was evaluated each two-month and follow-up was performed to achieve TTP and OS. Results: Among 30 patients, there were 3 patients of PR, 16 patients of SD, and 11 patients of PD, with clinical benefit rate (CBR) of 63.3%. Among 10 patients who took sorafenib alone, there were 1 patient of PR, 5 patients of SD, and 4 patients of PD, with CBR of 60.0%. Among 20 patients who took sorafenib in combination with TACE, there were 2 patients of PR, 11 patients of SD, and 7 patients of PD, with CBR of 65.0%. All 27 patients survived for more than 3 months, 24 patientssurvived for more than 6 months, 21 patients survived for more than 9 months, and 9 patients survived for even more than 1 year. TTP was 7 months, and OS was 9 months, with P=0.067 2 and P=0.058 9. Patients demonstrated adverse effects 1-2 weeks after administration. Twenty-three patients had hand and foot symptom, 24 patients had diarrhea, 14 patients had hypertension, 24 patients had fatigue, 9 patients had hair loss. There were 10 cases of degree 3 adverse reaction in total, and patients could accomplish the whole therapy

    Objective. The effectiveness of surgical resection of adenosquamous carcinoma of the lung remains poorly defined because of the histology' s relatively low frequency, the failure in most published series to separate adenosquamous carcinoma from the other variants of non-small cell lung carcinoma. To define the effectiveness of surgical treatment of adenosquamous carcinoma, we have retrospectively reviewed our hospital experience over a 12-year period. Methods. Retrospectively reviewed 22 cases of adenosquamous carcinoma who were surgically treated, except one patient,in the PUMCH from Jan. 1985 to Aug. 1997.This series constitutes the 1.9% of a total of 1 245 patients with all types of surgical treatment for the primary lung cancer during the same time. Results. The adenosquanous carcinoma was mostly presented in the old patients with a mean age of 60 years and mostly located in the peripheral of lung(n= 20).The overall 5-year survival was 23%.Those with stage Ⅰ tumors survival was only 18%(n= 13), stage Ⅱ 5%. The survival in stage Ⅲ tumors was not longer than 25 months and in stage Ⅳ survival was not longer than 12 months. Conclusion. Our results suggest that adenosquamous carcinoma of lung was a virulent tumor, which exhibited highly aggressive biological behavior with early lymph nodes metastasis(46% ) and its prognosis was worse than that of both squamous cell carcinoma and adenocarcinoma.

    Full Text Available The occurrence of a second malignancy in a patient with a known malignant tumour is not uncommon. Synchronous primary malignancies are still unusual We are presenting two cases treated successfully at our centre. Case report 1-A 70 year old female presented to us with lump in right breast for two years and bleeding per vaginum for two years.Histopathology of cervix showed squamous cell carcinoma (large cell non keratinizing and clinical stage was IIIB. HPE mastectomy specimen showed infiltrating duct carcinoma and stage II. Patient was treated with external beam radiotherapy for carcinoma cervix and breast simultaneously and chemotherapy as required. Patient is on regular follow up and clinically no evidence of disease. Case Report 2 -A 40 year old female presented with mild headache off and on for one year, projectile vomiting for three months and right side facial swelling for three months. HPE brain tissue showed astrocytoma grade II and HPE parotid tumour showed low grade muco-epidermoid carcinoma. Patient was treated with surgery first then radiotherapy. Patient is in regular follow up,having no complain,clinically no neurological dysfunction and no evidence of disease at right parotid and neck region. Thus it was concluded that patients responded well to treatment. Treatment strategies in case of synchronous double malignancy depend on treating the malignancy that is more advanced first or sometimes both could be treated simultaneously. In our case we concluded that synchronous double malignancy may be treated successfully. Both sites should be treated fully as if they were occurring separately considering toxicities.

We retrospectively collected tumor samples and reviewed clinical data of 53 patients with unresectable or metastatic UC, who were treated with first-line GP. RRM1 and ERCC1 expression were measured by immunohistochemistry. Among 53 patients, 12 (22.6% and 26 (49.1% patients had tumors that demonstrated a high expression for RRM1 and ERCC1, respectively. Twenty-nine (70.7% of 41 patients with low RRM1 expression achieved a clinical response (complete + partial responses, but only 3 (25.0% of 12 patients with high RRM1 expression achieved a clinical response after GP (P=0.007. Nineteen (70.4% of 27 patients with low ERCC1 expression achieved a clinical response, while 13 (50.0% of 26 patients with high ERCC1 expression achieved a clinical response (P=0.130. High RRM1 expression was associated with shorter progression free survival and overall survival (PFS P=0.006, OS P=0.006. Multivariate analysis confirmed that patients with high RRM1 expression had a significantly greater risk of progression and death than those with low RRM1 expression. ERCC1 status was not a significant predictor for PFS and OS. RRM1 expression was predictive and prognostic of clinical outcome in advanced UC treated with gemcitabine plus platinum combination chemotherapy.

    Renal preservation therapy has been a promising concept for the treatment of localized renal cell carcinoma (RCC) for 20 years. Nowadays partial nephrectomy (PN) is well accepted to treat the localized RCC and the oncological control is proved to be the same as the radical nephrectomy (RN). Under the result of well oncological control, minimal invasive method gains more popularity than the open PN, like laparoscopic partial nephrectomy (LPN) and robot assisted laparoscopic partial nephrectomy...

  2. Carcinoma cheek: regional pattern and management

    International Nuclear Information System (INIS)

    Oral cancer varies globally and regionally, and is closely linked with geographical, social, economical, biological, ethnic, dietary and environmental factors. In western countries it accounts for about 2 - 5% while in the south-east Asia for about 40% of all cancers. In Pakistan it is second commonest tumour after bronchogenic carcinoma in males and breast carcinoma in females. The objectives of this study were to find out the pattern of carcinoma cheek in our region, its etiological associations, management and prognosis. This study was conducted in the Otolaryngology and Head and Neck Surgery Department of Civil Hospital, Karachi from April 1995 to December 1998. It was prospective study. Methods: Forty-five cases of primary carcinoma cheek were diagnosed and investigations including OPG and CT scan were carried out along with other required investigations to evaluate the extension of tumour, bony erosion and metastasis. TNM staging was done. All patients were treated surgically, sent for post-operative radiotherapy or chemo radiation and followed up for 3 years. Result: Among 45 cases of oral cancer, 28 were females and 17 were males. Common presenting symptom was growth or ulcer. It was more common in 41 - 50 years of age. Squamous cell carcinoma (SCC) was found in 95.5% of the cases. Most of the patients 31 (68%) were in T4 stage. Surgical excision was done in all cases with reconstruction in 23 cases and neck dissection in 39 cases. In the follow up for 3 years, 30 patient remained disease free. Conclusion: Carcinoma cheek is a common entity in our region and now it is seen in relatively younger patients. Oral cancer is a self preventable disease. What is required is to develop awareness of oral hygiene and discourage the habit of social carcinogens use. Early diagnosis and treatment offers better chance of cure whereas advance disease has a poor prognosis. (author)

  3. Occult breast carcinoma presenting as axillary metastases

    International Nuclear Information System (INIS)

    Purpose: Breast carcinoma presenting with axillary lymphadenopathy and no clinical or radiological evidence of a primary tumor is a rare presentation. We aimed to examine the management of the breast by observation, radiation therapy, or mastectomy. Methods and Materials: Departmental records from 1979 to 1996 of unknown primary presentations and cases of T0N1-2M0 breast carcinoma were reviewed to find cases of occult breast carcinoma presenting as axillary lymphadenopathy with no clinical or imaging evidence of a primary tumor. Results: There were 6047 presentations of breast carcinoma with 20 cases of occult breast carcinoma meeting the criteria. The breast was treated by observation in 6 cases, mastectomy in 2 cases, and radiotherapy to the intact breast in 12 cases. Eighty-three percent of patients (5 of 6 patients) who had observation of the breast had a local recurrence, compared to 25% who had radiotherapy to the intact breast (3 of 12 patients) and 0% who had a mastectomy (0 of 2 patients). The median recurrence-free survival was 7 months in patients who had observation of the breast, compared to 182 months in patients who had local treatment. Three of the 6 patients who underwent breast observation have died whereas 1 of the 14 who had local treatment have died, with a mean follow-up of 73 months. It was found that patients having observation of the breast had a poorer recurrence-free survival (p = 0.003) and overall survival (p = 0.05) compared to those having local treatment of the breast. Conclusions: Patients with such a presentation should have a complete physical examination, mammography, ultrasound, and MRI of the breasts. If there remains no evidence of a primary tumor, an axillary dissection should be carried out and the breast treated by radiotherapy or mastectomy. Observation of the breast is not a recommended option

    Bruno Vincenzi

    Full Text Available The European Association for the Study of the Liver (EASL criteria and the modified Response Evaluation Criteria in Solid Tumors (mRECIST are currently adopted to evaluate radiological response in patients affected by HCC and treated with loco-regional procedures. Several studies explored the validity of these measurements in predicting survival but definitive data are still lacking.To conduct a systematic review of studies exploring mRECIST and EASL criteria usefulness in predictive radiological response in HCC undergoing loco-regional therapies and their validity in predicting survival.A comprehensive search of the literature was performed in electronic databases EMBASE, MEDLINE, COCHRANE LIBRARY, ASCO conferences and EASL conferences up to June 10, 2014. Our overall search strategy included terms for HCC, mRECIST, and EASL. Loco-regional procedures included transarterial embolization (TAE, transarterial chemoembolization (TACE and cryoablation. Inter-method agreement between EASL and mRECIST was assessed using the k coefficient. For each criteria, overall survival was described in responders vs. non-responders patients, considering all target lesions response.Among 18 initially found publications, 7 reports including 1357 patients were considered eligible. All studies were published as full-text articles. Proportion of responders according to mRECIST and EASL criteria was 62.4% and 61.3%, respectively. In the pooled population, 1286 agreements were observed between the two methods (kappa statistics 0.928, 95% confidence interval 0.912-0.944. HR for overall survival (responders versus non responders according to mRECIST and EASL was 0.39 (95% confidence interval 0.26-0.61, p<0.0001 and 0.38 (95% confidence interval 0.24-0.61, p<0.0001, respectively.In this literature-based meta-analysis, mRECIST and EASL criteria showed very good concordance in HCC patients undergoing loco-regional treatments.

  6. Parotid area lymph node metastases from carcinoma of the skin

    International Nuclear Information System (INIS)

    From January 1966 through April 1980, 38 patients with squamous cell carcinoma and one patient with basal cell carcinoma of the skin with lymphatic metastases to the parotid area were treated with curative intent at the University of Florida. Fourteen were initially treated with surgery, nine inoperable patients were treated primarily with radiation therapy, and 16 were treated with planned combined therapy, i.e., superficial or total parotidectomies with preoperative or postoperative radiation therapy. The ultimate parotid area control rate for the group treated with radiation alone was 50%; there were no failures at doses above 6500 rad. The parotid area control rate was 88% in the combined-treatment group with no failures when the surgical margins of resection were free; however, when gross residual disease was left behind, only 4 to 6 lesions were controlled. The major sequela from combined therapy was sacrifice of the seventh nerve at surgery. Treatment methods are discussed

  7. Interstitial brachytherapy for eyelid carcinoma. Outcome analysis in 60 patients

    International Nuclear Information System (INIS)

    Eyelid cancer is a therapeutic challenge due to the cosmetic and functional implications of this anatomical region and the objectives of therapy are tumor control, functional and cosmetic outcome. The present study was performed to analyze local control, toxicity, functional and cosmetic results in patients with eyelid carcinoma treated by interstitial brachytherapy. In this study 60 patients with eyelid carcinoma were treated by interstitial brachytherapy using iridium (192Ir) wires with a linear activity of 1.2-1.7 mCi/cm. The prescription dose was 51-70 Gy (mean 65 Gy, median 66 Gy). Of the 60 patients 51 (85.0 %) had received no prior treatment, 4 (6.7 %) had received previous surgery with positive or close margins and 5 (8.3 %) had suffered local recurrence after surgery. Of the tumors 52 (86.7 %) were basal cell carcinoma, 7 (11.7 %) squamous cell carcinoma and 1 (1.7 %) Merkel cell carcinoma. Clinical stage of the 51 previously untreated tumors was 38 T1N0, 12 T2N0 and 1 T3N0. Mean follow-up was 92 months (range 6-253 months). Local control was maintained in 96.7 % of patients. Late effects higher than grade 2 were observed in 3.0 % of cases. Functional and cosmetic outcomes were optimal in 68.4 % of patients. Interstitial brachytherapy for carcinoma of the eyelid can achieve local control, cosmetic and functional results comparable to those of surgery. (orig.)

    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.

  13. Preoperative hypoxyradiotherapy of colorectal carcinoma

    International Nuclear Information System (INIS)

    Aim: The article focuses on the radioprotective effect of acute hypoxia on healthy tissues during preoperative accelerated hypoxyradiotherapy of colorectal carcinoma performed as locoregional irradiation including the common iliac lymph nodes. Analysis of early and late side effects and complications. Patients and Methods: In this prospective study, early and late complications were assessed in 50 patients as a function of hypoxyradiotherapeutic dose increase. The preliminary treatment results of this radiotherapeutic modification were evaluated after a median follow-up of 48 months using Kaplan-Meier analysis. Between April 1991 and February 1997, 50 patients (36 men and 14 women) with colorectal carcinoma were treated preoperatively with locoregional accelerated hypofractionated hypoxyradiotherapy. The extent of disease was classified according to Dukes' criteria (A: four patients, B: 28 patients, C: 18 patients). We used a 20-MeV linear accelerator with two parallel opposed fields. Hypoxyradiotherapy was performed extending from the perineum to the L4 region. Acute hypoxia was induced during irradiation by ventilation of a hypoxic gas mixture containing 7.8-8.0% oxygen. Total doses of 24 Gy/8 days, 28 Gy/9 days, and 32 Gy/10 days were applied in five, 20, and 25 patients, respectively. Low anterior resection or abdominoperineal amputation of the rectum was performed the day after completion of preoperative hypoxyradiotherapy. The early reactions after irradiation were evaluated according to the Common Toxicity Criteria of the National Cancer Institute (CTC-NCI). Results: Early postirradiation proctitis was documented in three and early radiation-induced cystitis in two patients only. Neither early nor late radiation-associated complications were observed in any of the three hypoxyradiotherapy schedules during the follow-uper period of 6-105 months. Based on Kaplan-Meier analysis (median 48 months), a 5-year overall survival rate of 61.5% and a local relapse

    The incidence of hepatocellular carcinoma (HCC), a common neoplasm, is rising and the prognosis is poor. Many factors have to be taken into account when deciding on the best mode of therapy, like tumor size and number, liver function, sequelae of portal hypertension or other comorbidities. These factors are reflected in the Barcelona Clinic Liver Cancer (BCLC) classification. Resection, radiofrequency ablation (RFA) and liver transplantation can be seen as curative therapies for the early and localized HCC. For the intermediate state of the HCC, there are other therapeutic modalities in therapy available: transarterial chemoembolization (TACE), selective internal radiation therapy (SIRT, rarer occasions), off label: stereotactic body radiation therapy (SBRT). At the moment, Sorafenib is the only option in treating advanced stages of HCC. Alternative treatment strategies, like e.g. immunological therapies, are being investigated. PMID:26182255

    Ovarian tumors comprise a heterogeneous group of lesions, displaying distinct tumor pathology and oncogenic potentiel. These tumors are subdivided into three main categories: epithelial, germ cell, and sex-cord stromal tumors. We report herein the newly described molecular abnormalities in epithelial ovarian cancers (carcinomas). Immunohistochemistry and molecular testing help pathologists to decipher the significant heterogeneity of this disease. Our better understanding of the molecular basis of ovarian carcinomas represents the first step in the development of targeted therapies in the near future.

    AIM: To study the behavior as well as optimal treatment of gallbladder sarcomatoid carcinoma, we reviewed the results of treatment of gallbladder sarcomatoid carcinoma from Chang Gung Memorial Hospital. METHODS: From 1987 to 2005, six patients were diagnosed with gallbladder sarcomatoid carcinoma and treated at our institution. Tumor staging was based on 2002 revised tumor-node-metastasis (TNM) staging for gall bladder cancer from the American Joint Committee on Cancer. The clinical presentation, laboratory data and preoperat ive workup were reviewed retrospectively. RESULTS: Five patients were female and one was male. The age ranged from 51 to 66 years (median, 58 years). Surgical procedures included three curative resections, two palliative resections and one biopsy. There were two surgical complications (33.3%) and one case of surgical mortality (16.7%). The followup time ranged from 30 d to 5 mo. The median survival was 2.5 mo. The prognosis was extremely poor, even after curative resection and postoperative chemotherapy. CONCLUSION: The prognos i s of gal lbladder sarcomatoid carcinoma was not dependent on TNM stage and was always dismal. The clinicopathological features were different from those of gall bladder cancer.

    OBJECTIVE To determine the ideal method of surgical preoperative treatment for perforation with esophageal carcinoma.METHODS 36 cases of perforation with esophageal carcinoma were treated surgically in this series.Perforations occurred into the right lung in14 cases ,the mediastinum in 17 cases and trachea in 5 cases.Open thoracic surgery was performed in 34 cases,in which the right thoracic approach using a 3-incision method was applied in 16 cases,and operation by stages in 15 cases.Of the 34 cases,retrosternal substitution of the esophagus with stomach or colon was performed in 26 cases.RESULTS Surgery was successful in 31 cases and operative death occurred in 3 cases.The postoperative follow up study was from 3~72months.Of these cases 15 wree alive at 7~12 months, 2 at 24 months,and 1 at 72 months. The results can be considered satisfactory.CONCLUSION The therapeutic results of surgical treatment of perforation with esophageal carcinoma were markedly superior to that of conventional conservative treatment. The authors suggest that surgical intervention without delay should be undertaken for patients having a perforation with carcinoma of the esophagus. A right thoracic approach with a 3-incision method (retrosternal replacement of esophagus with stomach or colon) or operation by stages is preferable.

  3. Effect of administration of some antitumor extracts on Ehrlich ascites carcinoma-bearing mice

    International Nuclear Information System (INIS)

    Cancer is considered one of the most common causes of morbidity and mortality worldwide. Many researches have been studied on the discovery of natural and synthetic compounds that can be used in the prevention and/or treatment of cancer. Many chemo preventive agents have been associated with antiproliferative and apoptotic effects on cancer cells because of their high antioxidant activity. The present study was undertaken to investigate the antioxidant and antitumor effects of three natural extracts including (propolis, green tea and Chlorella vulgaris) without or with radiation exposure in Ehrlich ascites carcinoma (EAC) - bearing female albino mice. The animals were randomly distributed into three major groups as follows:- Group A (control group).This group consists of 10 mice kept on normal standard rodent diet without any treatment and housed in two cages: mice of the first cage served as control for non tumor-bearing group and the second cage served as control for tumor-bearing group. Group B (Non tumor - bearing group).This group consists of 30 mice and used to study the effect of the vehicle solutions (gum acacia, DMSO), propolis, green tea, Chlorella vulgaris and gamma irradiation on normal mice. Mice of this group were equally distributed into six subgroups receiving gum acacia, DMSO, propolis, green tea and Chlorella vulgaris for two weeks and whole body gamma irradiated. Group C (Tumor- bearing group): This group consists of 160 mice randomly and equally distributed into 8 subgroups: Ehrlich ascites carcinoma(mice were inoculated with 2.5 x 106 intra-peretoneally(i.p), Ehrlich ascites carcinoma and 2 Gy irradiated, Ehrlich ascites carcinoma and propolis treated (150 mg/kg b.w), Ehrlich ascites carcinoma, propolis treated and irradiated, Ehrlich ascites carcinoma and green tea treated (150 mg/kg b.w), Ehrlich ascites carcinoma, green tea treated and irradiated, Ehrlich ascites carcinoma and Chlorella vulgaris treated (150 mg/kg b.w) and Ehrlich ascites

    Uterine clear cell carcinoma (UCC) and uterine papillary serous carcinoma (UPSC) are rare entities that differ in clinical behavior from endometrial adenocarcinoma. Compared with endometrioid adenocarcinoma, they more often metastasize early and more commonly in the upper abdomen including the omentum. Treatment programs of UCC and UPSC at different stages vary and range from no adjuvant therapy in stage Ia to a wide variety of chemotherapies and radiotherapies in more advanced stages. This study presents the outcome of 109 patients with UCC or UPSC treated according to essentially the same treatment program from May 1993 to December 2004. Most patients were treated with a simple hysterectomy with no further adjuvant treatment. In stage Ia, 2/46 patients died of their disease and amongst all the stages, 30/109 patients died of their disease. These survival outcomes are comparable to or better than those presented previously. PMID:20944161

    Merkel cell carcinoma is a rare tumour of the skin. It affects predominantly elderly Caucasian males on sun-exposed areas of the skin. Distinctively more frequent and at significantly lower age, its incidence is higher in immunocompromised patients. In these patients we often observe the highly aggressive course of Merkel cell carcinoma and a fatal outcome. The incidence of Merkel cell carcinoma has been rising in recent years and is more dramatic than the increased incidence of cutaneous melanoma. More than one-third of Merkel cell carcinoma patients will die from this cancer, making it twice as lethal as melanoma. The malignant transformation of Merkel cells is currently thought to be related to an infection with Merkel cell polyomavirus. In the early stage the discreet clinical picture may be contrary to extensive microscopic invasion and this seemingly benign appearance can delay diagnosis or increase the risk of insufficient tumour excision. The diagnosis is definitely confirmed by histological evaluation and immunohistochemical tests. A typical feature is the tendency of Merkel cell carcinoma to frequent local recurrence and early metastasizing into regional lymph nodes with subsequent tumour generalization. The mainstay of therapy is radical excision of the tumour and adjuvant radiotherapy targeted at the site of primary incidence and local draining lymph nodes. The efficacy of different chemotherapy protocols in Merkel cell carcinoma is limited and the median survival rate is measured in months. In the future, prophylaxis with vaccination against Merkel cell polyomavirus will hopefully be possible in high-risk patients, as well as therapeutic usage of antisense oligonucleotides or microRNAs, eventually complete Merkel cell carcinoma elimination by affecting the tumour suppressor gene Atonal homolog 1 expression. The staging of the tumour at time of diagnosis is the most important prognostic factor. In this respect, the importance of preventative skin

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

    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 Metastasis to the skin in laryngeal squamous cell carcinoma is an extremely rare occurrence. We report a case of multiple cutaneous metastases in the follow-up of a 60-year-old male with squamous carcinoma of the vocal cords that were treated with surgery and radiotherapy. The patient presented with multiple painful skin nodules at 3 months following the completion of treatment. Clinically the skin nodules mimicked an inflammatory skin lesion. The diagnosis of metastatic skin lesions was made by cytological examination. Appearance of new painful skin lesions soon after the completion of treatment in patients treated for squamous carcinoma of the larynx should warrant a clinical suspicion of cutaneous metastases.

    Objective To evaluate clinical feasibility and efficacy of endoscopic metal stenting combined with radiotherapy for treatment of medium and late stages of esophageal carcinoma. Methods Thirty-four patients of late stage esophageal carcinoma were treated with endoscopic stent implantation in combination with radiotherapy. Evaluations of CES stainless steel metal stent on the effect of radiation, clinical symptom alleviation and complication and survival rates in both groups were made. Conclusion Endoscopic metal stenting in combination with radiotherapy was a feasible and practical management in treating medium and late stages esophageal carcinoma and was superior to simple metal stent implantation.

  14. Radical radiotherapy for carcinoma of the vulva

    International Nuclear Information System (INIS)

    A study was made of 58 patients with carcinoma of the vulva treated by radical radiotherapy between 1965 and 1982. The choice of treatment technique was influenced by site and extent of disease as well as the general condition of the patient. The crude 5-year survival was 26% (15/58). Local control was achieved in 40% of cases and was associated with tumour size of 4 cm or less. Radionecrosis occurred in nine cases but none of these required surgical intervention. Surgery remains the treatment of choice for carcinoma of the vulva. This report emphasizes that radical radiotherapy has a curative potential in those cases considered unsuitable for surgery and that the necrosis type and rate are within the limits of acceptable morbidity.

  16. Radiation therapy for carcinoma of the vulva

    International Nuclear Information System (INIS)

    Thirty-three patients suffering from squamous cell carcinoma of the vulva were treated with radiation therapy alone between 1961 and 1980 at the NIRS. The five-year survival rate and local control rate in each stage were 91 % and 36 % in T2 and 71 % and 64 % in T3, respectively. These results indicated that the early detection of recurrent tumor by close follow-up and an adequate retreatment procedure is very important for prologing survival. Late recurrence, more than five years after treatment, appeared in 30 % of the patients and this may be one of the special figures of postirradiated vulval carcinoma. The primary site was irradiated with external electron beams or radium needles, and better results were obtained with the later. Irradiation to the lymph node area in the pelvic cavity was necessary in patients with a more advanced stage of disease than T2. (author)

    Hepatocellular carcinoma (HCC) is an important cause of increasing mortality in elderly hemophilia population. Majority of the patients treated with virus non-inactivated factor concentrates prepared from large plasma pools prior to 1985 have been found to be infected with hepatitis C virus (HCV), a major risk factor for HCC. A PubMed search of articles published until February 2015 was performed utilizing the keywords hemophilia, malignancy, neoplasm, cancer, mortality, ageing hemophilia, epidemiology, hepatocellular carcinoma and liver cancer and the relevant articles were included. Contradictory reports are available in literature on the incidence of cancers in general in hemophilia population. Almost all the studies where the incidence of HCC or mortality due to HCC have been analyzed in hemophilia population show that a vast majority of these patients are HCV infected. The incidence of HCC though higher in hemophilic population is related to the higher incidence of HCV infection and not due to the hemophilia phenotype.

    Full Text Available The primary small cell carcinoma of the vagina is rare, and it is a highly aggressive malignancy with no consensus regarding the treatment of this tumor. The survival rate for patients treated in the early stages is around two years. We related the case report of a patient of 41 years with a vegetative and necrotic lesion in left vaginal wall, in middle and upper third, and involvement of parametrium in its proximal third and medium third. A biopsy showed a small cell undifferentiated carcinoma composed of epithelial cells with round nuclei, oval or elongated, hyperchromatic nuclei, with little distinct nucleoli, and scarce cytoplasm. Immunohistochemistry showed positivity for AE1/AE3, CD57, and chromogranin A. The patient received 6 cycles of chemotherapy with cisplatin and etoposide and radiotherapy, achieving complete response, with complete regression of the lesion. The patient had no sign of tumor recurrence and locoregional or distant metastases after 5 months of followup.

    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.

    Full Text Available Introduction. Primary fallopian tube carcinoma is extremely rare, making 0.3-1.6% of all female genital tract malignancies. Although the etymology of this tumor is unknown, it is suggested to be associated with chronic tubal inflammation, infertility, tuberculous salpingitis and tubal endometriosis. High parity is considered to be protective. Cytogenetic studies show the disease to be associated with over expression of p53, HER2/neu and c-myb. There is also some evidence that BRCA1 and BRCA2 mutations have a role in umorogeneis. Clinical features. The most prevailing symptoms with fallopian tube carcinoma are abdominal pain, abnormal vaginal discharge/bleeding and the most common finding is an adnexal mass. In many patients, fallopian tube carcinoma is asymptomatic. Diagnosis. Due to its rarity, preoperative diagnosis of primary fallopian tube carcinoma is rarely made. It is usually misdiagnosed as ovarian carcinoma, tuboovarian abscess or ectopic pregnancy. Sonographic features of the tumor are non-specific and include the presence of a fluid-filled adnexal structure with a significant solid component, a sausage-shaped mass, a cystic mass with papillary projections within, a cystic mass with cog wheel appearance and an ovoid-shaped structure containing an incomplete separation and a highly vascular solid nodule. More than 80% of patients have elevated pretreatment serum CA-125 levels, which is useful in follow-up after the definite treatment. Treatment. The treatment approach is similar to that of ovarian carcinoma, and includes total abdominal hysterectomy and bilateral salpingo-oophorectomy. Staging is followed with chemotherapy.

    The onset of hepatocellular carcinoma (HCC) is related to the development of non-neoplastic liver disease, such as viral infections and cirrhosis. Even though patients with chronic liver diseases undergo clinical surveillance for early diagnosis of HCC, this cancer is often diagnosed in advanced stage. In this case locoregional treatment is not possible and systemic therapies are the best way to control it. Until now sorafenib, a Raf and multi-kinase inhibitor has been the best, choice to treat HCC systemically. It showed a survival benefit in multicenter phase III trials. However the proper patient setting to treat is not well defined, since the results in Child-Pugh B patients are conflicting. To date various new target drugs are under developed and other biological treatments normally indicated in other malignancies are under investigation also for HCC. These strategies aim to target the different biological pathways implicated in HCC development and progression. The target drugs studied in HCC include anti-VEGF and anti-EGFR monoclonal antibodies, tyrosine kinase inhibitors and mTOR inhibitors. The most important challenge is represented by the best integration of these drugs with standard treatments to achieve improvement in overall survival and quality of life.

    BACKGROUND: Hepatocellular carcinoma (HCC) is one of the most frequent primary malignant tumors in the world. Hepatic resection and liver transplantation are considered optimal for potential treatment of HCC. However, only 20%of HCCs can be surgically treated. And most of surgically-noneligible patients have to receive interventional managements including local ablation and transarterial chemoembolization (TACE). In this paper, we review the interventional treatments of HCC. DATA SOURCES:A literature search of PubMed database was conducted and research articles were reviewed. RESULTS: Percutaneous ethanol injection (PEI) is usually applied to small HCC for a complete necrosis. Radiofrequency ablation, an alternative to PEI, also causes tumor necrosis and needs fewer times of ablation. Other methods such as acetic acid injection, laser, microwave, etc have enriched local ablation for HCC. High intensity focus ultrasound (HIFU) is thought to be promising. TACE, another common modality, can improve the survival rate of patients with HCC. The newly developed embolic agents and adjuvant rAd-p53 gene therapy are well reported. CONCLUSIONS:Surgically-noneligible HCC can be treated with interventional procedures. Each method has its advantages and disadvantages. However, it is still pressing to develop ablative methods as well as new embolic agents for a better prognosis of HCC.

    Twenty-six patients with cholangiocarcinoma and nineteen patients with carcinoma of the gallbladder treated with external radiotherapy were analyzed. Of the twenty-six patients, eighteen had cancer of the hepatic hilus (Klatskin), four intrahepatic and the remaining four extrahepatic cholangiocarcinoma. All but two of the patients had advanced disease. Thirty-three patients received primary irradiation for unresectable tumors, ten patients adjuvant irradiation after non-curative gross tumor resection, and two patients preoperative radiotherapy. Patients with cholangiocarcinoma who underwent radiotherapy with relatively small radiation field tolerated the treatment well, but there was no significant difference in survival according to field size or radiation doses (TDF). On the other hand, patients with carcinoma of gallbladder were treated with larger field size and lower dose. In the patients without gross tumor resection, those receiving radiation doses[>=]90 TDF had significantly longer survival than <90 TDF (p<0.05). Regarding to the field size, patients irradiated by smaller field size ([<=]100 cm[sup 2]) had longer survival (p=0.07). The patients with gross tumor resection had significantly longer survival than that without resection in both cholangiocarcinoma and carcinoma of gallbladder. Postmortem examination revealed tumor recurrence even in the patients with gross tumor resection, but widespread distant metastases were present simultaneously. Cholangitis and liver abscess were special and lethal conditions related to these carcinomas, and intensive therapy must be developed for these conditions. External radiotherapy may be effective in the treatment of bile duct carcinoma in terms of palliation and survival. (author).

    Purpose: The aim of this study was to evaluate the effectiveness of low-dose-rate brachytherapy for local control and relapse-free survival in squamous cell and basal cell carcinomas of the lips. We compared two groups: one with tumors on the skin and the other with tumors on the lip. Patients and methods: All patients had been treated at Claudius Regaud Cancer Centre from 1990 to 2008 for squamous cell or basal cell carcinoma. Low-dose-rate brachytherapy was performed with iridium 192 wires according to the Paris system rules. On average, the dose delivered was 65 Gy. Results: 172 consecutive patients were included in our study; 69 had skin carcinoma (squamous cell or basal cell), and 92 had squamous cell mucosal carcinoma. The average follow-up time was 5.4 years. In the skin cancer group, there were five local recurrences and one lymph node recurrence. In the mucosal cancer group, there were ten local recurrences and five lymph node recurrences. The 8-year relapse-free survival for the entire population was 80%. The 8-year relapse-free survival was 85% for skin carcinoma 75% for mucosal carcinoma, with no significant difference between groups. The functional results were satisfactory for 99% of patients, and the cosmetic results were satisfactory for 92%. Maximal toxicity observed was Grade 2. Conclusions: Low-dose-rate brachytherapy can be used to treat lip carcinomas at Stages T1 and T2 as the only treatment with excellent results for local control and relapse-free survival. The benefits of brachytherapy are also cosmetic and functional, with 91% of patients having no side effects.

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

  12. Functional screen of paracrine signals in breast carcinoma fibroblasts.

    Directory of Open Access Journals (Sweden)

    Gui Su

    Full Text Available Stromal fibroblasts actively participate in normal mammary gland homeostasis and in breast carcinoma growth and progression by secreting paracrine factors; however, little is known about the identity of paracrine mediators in individual patients. The purpose of this study was to characterize paracrine signaling pathways between breast carcinoma cells and breast carcinoma-associated fibroblasts (CAF or normal mammary fibroblasts (NF, respectively. CAF and NF were isolated from breast carcinoma tissue samples and adjacent normal mammary gland tissue of 28 patients. The fibroblasts were grown in 3D collagen gel co-culture with T47D human breast carcinoma cells and T47D cell growth was measured. CAF stimulated T47D cell growth to a significantly greater degree than NF. We detected a considerable inter-individual heterogeneity of paracrine interactions but identified FGF2, HB-EGF, heparanase-1 and SDF1 as factors that were consistently responsible for the activity of carcinoma-associated fibroblasts. CAF from low-grade but not high-grade carcinomas required insulin-like growth factor 1 and transforming growth factor beta 1 to stimulate carcinoma growth. Paradoxically, blocking of membrane-type 1 matrix metalloprotease stimulated T47D cell growth in co-culture with NF. The results were largely mirrored by treating the fibroblasts with siRNA oligonucleotides prior to co-culture, implicating the fibroblasts as principal production site for the secreted mediators. In summary, we identify a paracrine signaling network with inter-individual commonalities and differences. These findings have significant implications for the design of stroma-targeted therapies.

  13. Brachytherapy as sole treatment modality in initial cervix carcinoma

    International Nuclear Information System (INIS)

    The aim of this study was to evaluate brachytherapy as the only treatment modality in inoperable early cervix carcinoma patients (carcinoma in situ, IA and IBocc). In a retrospective analysis 36 patients were treated with intracavitary irradiation between 1984 and 1988 in the Radiotherapy Department of the National Institute of Neoplasmic Diseases. Distribution by stage was; carcinoma in situ: one patient (2,47%), IA: six patients (16,6%), IBooc: twenty-nine patients (80,7%). Histology revealed epidermoid carcinoma in all cases. Mean age 55 years (range: 32-78). Treatment consisted in: two intracavitary applications of Radium, for 120 hours each, with a month interval, in 30 patients (carcinoma in situ: one, IA: four, IBocc: twenty-five patients), two applications of 72 hours each, with 15 days interval in four patients (IA: one, IBocc: 3) and one single intracavitary radium application in two patients (IA and IBocc). Local control was complete in all carcinoma in situ and IA patients. Only 1 of 29 patients with IBocc stage failed to respond, in spite of having received two applications, this shows that local response is independent of the number of insertions. Incidence of complications was low, and resolved with medical treatment. One patient had rectal adenocarcinoma 3 years after treatment -it was considered as radio induced neoplasm, since time of appearance was more than two years and localization was within irradiated area. Two patients died form intercurrent diseases, one (IBocc) from persistent diseases. Two patients were lost to follow-up. Three years survival was: 100% for carcinoma in situ and IA 86,2% for IBocc. Five years survival was 80% for IA and IBocc. Brachytherapy as unique modality of treatment is highly effective in initial cervix carcinoma stages. (author). 41 refs., 14 tabs., 2 figs., 1 ill

    International Nuclear Information System (INIS)

    Objective: To evaluate the therapeutic outcome and determine the prognosticators of tonsillar carcinoma treated by different approaches. Methods: A retrospective study was done on 71 tonsillar carcinoma patients treated from August 1971 to October 1995 by three different ways of radiotherapy. All were pathologically proved. Fifteen patients received external bean therapy plus intracavitary brachytherapy (EBRT + BRT), 39 patients were treated by EBRT only (EBRT) and the other 17 patients underwent FBRT plus chemotherapy (EBTR + CHEMO). Results: The local control rates of EBRT + BRT, EBRT and EBRT + chemo were 82.1%, 68.4% and 64.2%. There was significant difference between EBRT + BRT and the other two groups (x2=4.65, P=0.030; x2=5.65, P=0.018). The 3-, 5- and 10- year survival rates of EBRT + BRT, EBRT and EBRT + CHEMO were 76.3%, 53.2%, 31.2%; 74.0%, 45.2%, 33.5% and 75.2%, 47.1%, 25.3%. All these survival rates showed no statistical significance. (P > 0.05). Conclusion: Brachytherapy, when used to increase the dose effect, may enhance the local effect without any change in the overall survival

  17. Bronchogenic Carcinoma in Khartoum

    International Nuclear Information System (INIS)

    The prospective study was conducted in the period between April 1996 and April 1997, and included 26 with bronchogenic carcinoma. The diagnosis was proved histologically in 24 patients, and it was based on the clinico-radiological picture in the remainder two patients. The mean age was 49 years,SD ±16.5. The male:female ratio was 2.2:1.0. All five patients under thirty years were females. 13 patients(50%) were smokers. The mean duration of smoking was 28 years, SD±8. The mean number of cigarettes per day was 24, SD±11.8. Chest symptoms and signs were observed in 92% and 48% of patients respectively, and 10 patients(38%) showed evidence of metastases at diagnosis. Bronchioscopic was done in 11 patients and transthorasic needle biopsy in 6. The diagnosis in the remainder of patients was confirmed by operative biopsy, or pleural cytology, or pleural biopsy or by biopsy from secondaries. The histology revealed squamous cell carcinoma in 14 patients, small cell carcinoma in 5, adenocarcinoma in 3, large cell carcinoma in 2, and the histology was not obtained in two patients. Radiotherapy alone was given to 9 patients. Ten patients underwent surgery followed by radiotherapy in 5 patients and chemotherapy in 4. Only 10 patients survived for more than 3 months. One patient survived for more than one year after diagnosis.(Author)

    96 women with primary carcinoma corporis uteri and 79 women after surgery were treated between 1965-1970 with different radiotherapeutic methods, in some cases in combination with cytostatics and gestagens. In the group of primary radiation best results were obtained with combination of intracavitary brachytherapy and external radiation (55% 5-years-survival), and in the postoperative group with external radiation alone (67% 5-years-survival). Late complications with 17% fibrosis in the parametrial tissue and 12% persistant diarrhea in the postoperative group needs strict individualization in therapy and requires exact knowledge on extention and biological behavior of the tumor.

    Actinomycosis is a rare, chronic, spreading, suppurative,granulomatous and fibrosing infection. Actinomyces are normal inhabitants of the oral cavity and gastrointestinal tract. They rarely cause disease and are seldom reported as pathogens. Herein, we reported on a 69-year-old male patient who had undergone Whipple's operation due to ampulla Vater carcinoma, and became infected with actinomycosis at the pancreaticojejunostomy, which mimicked a recurrent malignancy. He was treated with radical resection of the mass at the pancreaticojejunostomy and had an uneventful postoperative course.

    Uterine papillary serous carcinoma (UPSC) is an aggressive variant of endometrial cancer. Owing to its rarity, most clinicians are unfamiliar with the clinical aspects and management of UPSC. Furthermore, little prospective evidence exists regarding how best to treat this subset of patients. In anticipation of prospective clinical trials, this article summarizes the latest results of various clinical management options in the different substages of UPSC, with a special focus on the effects of cytoreductive surgery, comprehensive surgical staging and different adjuvant treatment options in relation to recurrence rate and survival outcome.

    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

    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.

    Purpose: This paper reports long-term results of RTOG 9903, to determine whether the addition of erythropoietin (EPO) would improve the outcomes of radiation therapy (RT) in mildly to moderately anemic patients with head and neck squamous cell carcinoma (HNSCCa). Methods and Materials: The trial included HNSCCa patients treated with definitive RT. Patients with stage III or IV disease received concomitant chemoradiation therapy or accelerated fractionation. Pretreatment hemoglobin levels were required to be between 9.0 and 13.5 g/dL (12.5 g/dL for females). EPO, 40,000 U, was administered weekly starting 7 to 10 days before RT was initiated in the RT + EPO arm. Results: A total of 141 of 148 enrolled patients were evaluable. The baseline median hemoglobin level was 12.1 g/dL. In the RT + EPO arm, the mean hemoglobin level at 4 weeks increased by 1.66 g/dL, whereas it decreased by 0.24 g/dL in the RT arm. With a median follow-up of 7.95 years (range: 1.66-10.08 years) for surviving patients and 3.33 years for all patients (range: 0.03-10.08 years), the 5-year estimate of local-regional failure was 46.2% versus 39.4% (P=.42), local-regional progression-free survival was 31.5% versus 37.6% (P=.20), and overall survival was 36.9% versus 38.2% (P=.54) for the RT + EPO and RT arms, respectively. Late toxicity was not different between the 2 arms. Conclusions: This long-term analysis confirmed that despite the ability of EPO to raise hemoglobin levels in anemic patients with HNSCCa, it did not improve outcomes when added to RT. The possibility of a detrimental effect of EPO could not be ruled out.

    Full Text Available Pituitary carcinoma is a rare malignancy and is difficult to manage. Pituitary carcinomas commonly produce either PRL or ACTH, but some do not produce pituitary hormones. The alkylating reagent temozolomide (TMZ was recently shown to be effective as a treatment for pituitary carcinoma. Most of the published reports of TMZ use in pituitary carcinoma cases were against hormone-producing carcinomas. Only a few patients with a nonfunctioning pituitary carcinoma treated with TMZ have been reported. Here we describe our treatment of a patient with nonfunctioning pituitary carcinoma and a background of multiple endocrine neoplasia type 1. The pituitary carcinoma was accompanied by meningeal dissemination with cerebral and L1 spinal bone metastasis. The patient received continuous dosing of TMZ along with external radiation, followed by standard dosing of TMZ. There was an apparent antitumor response seen in MRI. MGMT, an enzyme antagonized by TMZ, was negative in the tumor. The therapeutic efficacy of TMZ and dosing schedules of TMZ in pituitary carcinoma are discussed.

    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.

    Small cell lung carcinoma (SCLC) commonly metastasizes to distant organs. However, metastasis to the pancreas is not a common event. Moreover, obstructive jaundice as a first clinical presentation of SCLC is extremely unusual. This case reports a 51-year-old male with SCLC, manifesting with obstructive jaundice as the initial clinical presentation. Endoscopic retrograde cholangiopancreatograghy (ERCP) and abdominal computed tomography (CT) scan showed a mass at the head of the pancreas. The patient underwent pancreatoduodenectomy (Whipple procedure). Histopathology revealed a chromogranin- A-positive poorly-differentiated neuroendocrine carcinoma of the pancreas. No imaging study of the lung was performed before surgery. A few months later, a follow-up CT revealed unilateral lung nodules with ipsilateral hilar nodes. A lung biopsy was done and histopathology reported a TTF- 1-positive, chromogranin A-positive, small cell carcinoma of the lung. On review, the pancreatic tumour was also TTF-1-positive. He was then treated with combination chemotherapy (cisplatin, etoposide). These findings highlight that presentation of a mass at the head of pancreas could be a manifestation of a metastatic tumour from elsewhere such as the lung, and thorough investigations should be performed before metastases can be ruled out.

    NUT carcinoma (NC) is a recently described, rare and extremely aggressive cancer primarily located to supradiaphragmatic structures and affecting young individuals. NC is characterized by translocations involving the NUT gene on 15q14 with the most common translocation partner gene being BRD4 on 19p13, resulting in the t(15;19)(q14;p13) karyotype. NC is poorly differentiated and is likely to be overlooked and misdiagnosed as poorly differentiated squamous cell carcinoma (SCC) when immunohistochemical evaluation of NUT protein expression is omitted. Previously, NC has been found in the parotid and submandibular glands and we present the first case in the sublingual gland arising in a 40-year-old woman. We discuss the diagnostic considerations for poorly differentiated carcinomas of the salivary glands and advocate the inclusion of NUT immunohistochemistry in this setting. Not only does the NC diagnosis confer a grave prognosis when treated as SCC as illustrated by the present case, but is important for the inclusion of patients in ongoing clinical trials.

  12. Perineural Infiltration of Cutaneous Squamous Cell Carcinoma and Basal Cell Carcinoma Without Clinical Features

    International Nuclear Information System (INIS)

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

    Aim: The article focuses on the radioprotective effect of acute hypoxia on healthy tissues during preoperative accelerated hypoxyradiotherapy of colorectal carcinoma performed as locoregional irradiation including the common iliac lymph nodes. Analysis of early and late side effects and complications. Patients and Methods: In this prospective study, early and late complications were assessed in 50 patients as a function of hypoxyradiotherapeutic dose increase. The preliminary treatment results of this radiotherapeutic modification were evaluated after a median follow-up of 48 months using Kaplan-Meier analysis. Between April 1991 and February 1997, 50 patients (36 men and 14 women) with colorectal carcinoma were treated preoperatively with locoregional accelerated hypofractionated hypoxyradiotherapy. The extent of disease was classified according to Dukes' criteria (A: four patients, B: 28 patients, C: 18 patients). We used a 20-MeV linear accelerator with two parallel opposed fields. Hypoxyradiotherapy was performed extending from the perineum to the L4 region. Acute hypoxia was induced during irradiation by ventilation of a hypoxic gas mixture containing 7.8-8.0% oxygen. Total doses of 24 Gy/8 days, 28 Gy/9 days, and 32 Gy/10 days were applied in five, 20, and 25 patients, respectively. Low anterior resection or abdominoperineal amputation of the rectum was performed the day after completion of preoperative hypoxyradiotherapy. The early reactions after irradiation were evaluated according to the Common Toxicity Criteria of the National Cancer Institute (CTC-NCI). Results: Early postirradiation proctitis was documented in three and early radiation-induced cystitis in two patients only. Neither early nor late radiation-associated complications were observed in any of the three hypoxyradiotherapy schedules during the follow-uper period of 6-105 months. Based on Kaplan-Meier analysis (median 48 months), a 5-year overall survival rate of 61.5% and a local relapse

    OBJECTIVE To study the proper sites and doses of intraoperative radiotherapy (IORT) for gastric carcinoma and the effects of this treatment.METHODS A total of 106 cases of stage Ⅰ- Ⅳ gastric carcinoma who received a D2 or D3 radical resection operation combined with IORT were analyzed. Sixty-seven patients with gastric cancer of the antrum and body received distal gastrectomy. The sites of irradiation were at the celiac artery and hepatoduodenal ligament area. Another 39 patients with carcinoma of the cardia and upper part of the gastric body and whole stomach received proximal gastrectomy or total gastrectomy. The sites of irradiation for this group were the upper margin of the pancreas and the regional paraaorta.The therapeutic effects (including survival and complications) of these 106cases who received a combined operation IORT (IORT group) were compared with 441 cases treated during the same time period by a radical resection operation alone (operation group).RESULTS The radiation dose below 30 Gy was safe. The therapeutic method of the operation combined with IORT did not prolong the survival time of patients with stage Ⅱ and Ⅳ gastric cancer, but the 5-year survival rates of patients with stage Ⅱ and Ⅲ gastric cancers were significantly improved.While the 5-year survival rates of the stage Ⅲ cancer patients receiving D2 resection combined with IORT had marked improvement, for those receiving a D3 radical resection, only the postoperative survival rates at 3 and 4 years of those cases in stages Ⅲ cancers were improved (P<0.005-0.001). The 5-year survival rate for those patients was raised only 4.7%(P>0.05).CONCLUSION The 5-year survival rates of patients with stages Ⅱ and Ⅲ gastric carcinoma who received a D2 lymphadenectomy combined with IORT were improved and had no influence on the postoperative complications and mortality.

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

    Full Text Available Background. Simultaneous presence of Hashimoto's thyroiditis and papillary thyroidal carcinoma in thyroidal gland with papillary carcinoma association in thyroglossal duct is quite rare. The questions like where the original site of primary process, is where metastasis is, what the cause of coexisting of these diseasesis present a diagnostic dilemma. Case report. We presented a case of a 53-year old female patient, with the diagnosis of Hashimoto's thyroiditis and symptoms of subclinical hypothyreosis and nodal changes in the right lobe of thyroidal gland, according to clinical investigation. Morphological examination of thyroidal gland, ultrasound examination and scintigraphy with technetium (Tc confirmed the existence of nonhomogenic tissue with parenchyma nodular changes in the right lobe of thyroidal gland that weakly bonded Tc. Fine needle biopsy in nodal changes, with cytological analyses showed no evidence of atypical thyreocites. Hashimoto's thyroiditis was confirmed on the basis of the increased values of anti-microsomal antibodies, the high levels of thyreogobulin 117 ng/ml and TSH 6.29 μIU/ml. The operation near by the nodular change in the right lobe of thyroidal gland revealed pyramidal lobe spread in the thyroglossal duct. Total thyroidectomia was done with the elimination of thyroglossal duct. Final patohystological findings showed papillary carcinoma in the nodal changes pT2, N0 and in the thyroglossal duct with the presence of Hashimoto's thyroiditis in the residual parenchyme of the thyroid gland. After the surgery the whole body scintigraphy with iodine 131 (131I did not reveal accumulation of 131I in the body, while the fixation in the neck was 1%. After that, the patient was treated with thyroxin with suppressionsubstitution doses. Conclusion. Abnormality in embrional development of thyroidal tissue might be the source of thyroidal carcinoma or the way of spreading of metastasis of primary thyroidal carcinoma from thyroid

    2015-01-01

    Full Text Available Laryngeal spindle cell carcinoma (SpCC is an uncommon subtype of squamous cell carcinoma which represents 0.5% of all laryngeal squamous cell carcinomas. It is a biphasic tumor consisting of the combination of a malignant mesenchymal spindle cell component and a squamous cell component that includes dysplasia, carcinoma in situ, or invasive carcinoma. Although it has aggressive biological features, the probability of making a diagnosis in the early stages is high as it often leads to obstructive symptoms in the early period. Due to its low incidence, there is no clear consensus on prognostic factors and optimal treatment strategies yet. In this paper, a 60-year-old laryngeal SpCC case that was effectively treated with wide local excision followed by adjuvant radiotherapy was presented with the literature.

  5. Adenoid cystic carcinoma of sublingual glands. Surgery and radiotherapy combination

    International Nuclear Information System (INIS)

    The Adenoid Cystic Carcinoma (ACC) or Cilindroma is a strange entity classified by the WHO within the carcinomas of salivary glands. It represents only 1 % of all the wicked tumours of the oral and maxillofacial region although, when making reference to the salivary glands, it constitutes 5% of the parotid, submaxilar and sublingual carcinomas, and about 50% of the smallest ones. The most frequent location is in the palatine glands and its main characteristics are: slow but persistent growth, high rates of local relapse and metastasis at distance originating the death between the first 5 and 10 years in 50-70% of the cases approximately. A case of localization is presented in sublingual gland which was first treated surgically and later with radiotherapy, obtaining good results. (author)

    Small cell carcinoma of the uterine cervix accounts for 1-3% of all cervix cancers. It is an aggressive disease with a poor prognosis. To date, no effective treatment protocol has been determined. Surgery, radiotherapy, and chemotherapy have been used either alone or in combination. Recent data suggests that survival in patients with early staged small cell carcinoma of the cervix is better with surgery combined with chemo-radiotherapy. Here, we presented two patients with stage IB1 small cell carcinoma of the uterine cervix. For both patients, definitive surgery was performed with pelvic and para-aortic lymphadenectomy. Subsequently, they were treated with pelvic external radiotherapy and high-dose-rate intracavitary brachytherapy with concurrent cisplatin based chemotherapy. They were alive with no evidence of disease at 91 and 65 months, respectively.

    Sarcomatoid transitional cell carcinoma of the renal pelvis is a rare neoplasm with only 14 well-illustrated examples reported previously. Duplex kidney is the most common congenital abnormality of the urinary tract, with an incidence of around 2%. Neoplasia of the renal pelvis in duplex kidney is rare. We reported a case whose sarcomatoid carcinoma originated from the upper portion of the duplicated renal pelvis with hydronephrosis, and total nephroureterectomy with bladder cuff excision surgery of both renal units was carried out. Because of the rare nature of renal pelvic sarcomatoid carcinoma and its apparent lack of response to adjuvant therapy, it is essential to do early diagnosis and early radical surgery to improve survival. It is important to stress the need for frequent and diligent monitoring or treating complex duplex kidney with hydronephrosis of either moiety in case of a risk of having neoplasias.

    Full Text Available Myoepithelial carcinoma is a rare neoplasm of salivary glands that account for < 1% of all salivary gland tumors. The most common sites of involvement are major salivary glands mainly parotid gland. Intraorally, it can arise from minor salivary glands; palate is the most common site of occurrence. It also occurs in nasopharynx, paranasal sinuses, nasal cavity and larynx in head and neck region. Myoepithelial tumors were first described in 1943. Their malignant variant, myoepithelial carcinoma, was first reported by Stromeyer et al., in 1975, characterized by distinct morphologic heterogeneity and an infiltrative growth pattern into adjacent tissues. Here, we report a rare case of a 55-year-old female with myoepithelial carcinoma of buccal mucosa. It was also rare because of unusual location of tumor. Our patient was treated with wide local resection and remained free of disease for 15 months.

  9. Computed tomography in bronchogenic carcinoma- a pictorial essay

    International Nuclear Information System (INIS)

    Bronchogenic carcinoma is an extremely common and aggressive tumor, being the commonest cancer in men and the fourth commonest cancer in men and the fourth commonest cancer in women, ranking after breast, colon and skin cancers. The extent of the tumor has to be known accurately, as the treatment options change, based on the staging of the tumor. An advanced tumor cannot be resected and has to be treated by radiotherapy and/or chemotherapy. Computed Tomography (CT) is of great value in staging bronchogenic carcinomas and therefore helps in deciding the further management of the patient. In this pictorial essay, we illustrate the broad spectrum of abnormalities that can be shown by CT in bronchogenic carcinoma. (author). 21 refs., 21 figs

    Objective: To study the use of interventional chemotherapy in comprehensive treatment for advanced nasopharyngeal carcinoma. Methods: Interventional chemotherapy with multi-drugs including cisplatin (DDP) 100 mg, 5-fluorouracil (5-FU) 1000 mg and bleomycin (BLM) 16 mg was used to treat 30 cases with advanced nasopharyngeal carcinoma before radiotherapy. 50 cases that received radiotherapy alone were used as a control group. The methods, time and dose schedule of radiotherapy were similar in the two groups. Results: The primary lesions in 16 cases and the cervical lymph nodes in 12 cases were reduced in size after interventional chemotherapy. Radiation doses of those in complete response in their primary lesion and cervical lymph nodes were lower than that of the control group (P<0.05). The complete response rate of study group was 83.3% and that of control group was 72.0% (P<0.05). Conclusion: Interventional chemotherapy plus radiotherapy is a valuable treatment method in advanced nasopharyngeal carcinoma.

    Merkel cell carcinoma is a rare lymphophilic skin tumor of neuroendocrine origin with the potential for rapid progression. Small, localized lesions are diagnosed and treated clinically, but advanced tumors often undergo imaging evaluation. Due to its rarity, radiologists are unaware of evocative imaging features and usually do not consider Merkel cell carcinoma in the differential diagnosis of soft tissue tumors. Appropriate staging is important to determine appropriate treatment and has an impact on patient prognosis. Multimodality imaging is usually needed, and there is no consensus on the optimal imaging strategy. The purpose of this article is to review various aspects of Merkel cell carcinoma imaging and look in detail at how optimal multimodality staging should be carried out. (orig.)

    A few signaling pathways are driving the growth of hepatocellular carcinoma. Each of these pathways possesses negative regulators. These enzymes, which normally suppress unchecked cell proliferation, are circumvented in the oncogenic process, either the over-activity of oncogenes is sufficient to annihilate the activity of tumor suppressors or tumor suppressors have been rendered ineffective. The loss of several key tumor suppressors has been described in hepatocellular carcinoma. Here, we systematically review the evidence implicating tumor suppressors in the development of hepatocellular carcinoma.

    2012-02-01

    Thyroid carcinoma is the most commonly diagnosed endocrine malignancy. Its incidence is currently rising worldwide. The discovery of genetic mutations associated with the development of thyroid cancer, such as BRAF and RET, has lead to the development of new drugs which target the pathways which they influence. Despite recent advances, the prognosis of anaplastic thyroid carcinoma is still unfavourable. In this review we look at emerging novel therapies for the treatment of well-differentiated and medullary thyroid carcinoma, and advances and future directions in the management of anaplastic thyroid carcinoma.

    Introduction Nasopharyngeal carcinoma among the children has been rare accounting for only 1% of all pediatric malignancies. Both genetic and environmental factors have contributed to the development of nasopharyngeal carcinoma. Among the children there was a higher rate of undifferentiated histology. The mean age of nasopharyngeal carcinoma diagnosis has been 11 years old age; and the most common site was nasopharynx. Palpable lymphadenopathy, dysphasia and neural defect were common associated signs. Case Presentation A 15-year-old boy has presented with a mass that located near by the heart in the left side of mediastinum with invasion to anterior mediastinum from two years ago. In biopsy, nasopharyngeal carcinoma, non-keratinizing type, has diagnosed while there was no involvement of nasopharyngeal region. Patient has treated by 70 Gy (2.0 Gy/fraction) radiotherapy plus concomitant chemotherapy with base of docetaxel. But the mass had no regression. Then, the patient has treated with Cisplatin 100 mg/m2 IV on days 1, 22, and 43 with radiation, then cisplatin 80 mg/m2 IV on day 1 plus fluorouracil (5-FU) 1000 mg/m2/day by continuous IV infusion on days 1 - 4 every 4wk for 3 cycles and after remission interferon beta has added to treatment for 6 months duration as a maintenance therapy. After 1 year follow up; the patient was in complete remission. In the course of therapy, only hypothyroidism has occurred. Conclusions Nasopharyngeal carcinoma in childhood, without nasopharyngeal involvement, initially could be detected in other sites such as pericardium. Also good results could be respected by cisplatin and 5-fluorouracil based neoadjuvant chemotherapy before radiotherapy plus interferon beta as a maintenance therapy in childhood aggressive nasopharyngeal carcinoma.

    2012-01-01

    Full Text Available Alpha-fetoprotein-producing carcinoma (AFPC/hepatoid adenocarcinoma (HAC and neuroendocrine carcinoma (NEC are uncommon in the stomach. Composite tumors consisting of these carcinomas and their histologic phenotypes are not well known. Between 2002 and 2007, to estimate the prevalence of composite tumors consisting of tubular adenocarcinoma, AFPC/HAC and NEC, we reviewed specimens obtained from 294 consecutive patients treated surgically for gastric cancer. We examined histological phenotype of tumors of AFPC or NEC containing the composite tumor by evaluating immunohistochemical expressions of MUC2, MUC5AC, MUC6, CDX2, and SOX2. Immunohistochemically, AFPC/HAC dominantly showed the intestinal or mixed phenotype, and NEC frequently showed the gastric phenotype. In the composite tumor, the tubular and hepatoid components showed the gastric phenotype, and the neuroendocrine component showed the mixed type. The unique composite tumor predominantly showed the gastric phenotype, and the hepatoid and neuroendocrine components were considered to be differentiated from the tubular component.

  2. Radiation therapy for endometrial carcinoma

    International Nuclear Information System (INIS)

    Although pelvic irradiation has traditionally been employed as an adjunct to surgery, the role of radiation therapy as a definitive therapeutic modality continues to be controversial. One-hundred and twenty-one patients were treated for endometrial carcinoma between 1978 and 1985 at the Medical College of Virginia Hospital. These patients were divided into three groups with respect to their treatment. Group 1 consisted of 16 patients who had preoperative radiation therapy, group 2 consisted of 77 patients who had postoperative radiation therapy, and group 3 consisted of 28 patients who had radiation therapy alone. Ninety-three percent of the patients in groups 1 and 2 and 68% of patients in group 3 had stages I and II disease. In group 3, 32% of the patients had stages III and IV disease. Two-thirds of the patients in groups 1 and 2 had moderately differentiated tumor. One-third of patients in group 3 had poorly differentiated tumor. Sixty percent of the study's population in group 2 had deep myometrial invasion. The treatment doses utilized and local failures will be presented. All of the patients have been followed for a minimum period of 2 years. The observed actuarial 5-year survival was 85%, 80%, and 53%, respectively, for groups 1, 2, and 3. The overall survival of the entire patient population was 77%. There was 1 fatality secondary to small bowel complication in group 2 and another serious complication of rectovaginal fistula in group 1 requiring colostomy. Other side effects were skin reaction, diarrhea, and cystitis, which were treated symptomatically. Analysis of the authors' institution experience with adenocarcinoma of the endometrium and its management with radiation therapy is presented. Survival is correlated with stage, grade, and depth of myometrial invasion

    Aims: To describe the magnetic resonance imaging (MRI) features of vaginal carcinoma and to suggest a role for MRI in its management. Materials and methods: Twenty-five patients with primary vaginal carcinoma treated at our institution between 1996 and 2005 were included in the study. The MRI examinations were reviewed and tumour dimensions, signal characteristics and involvement of pelvic structures were documented, as were sites of enlarged lymph nodes and metastases. Details of patient treatment and outcome were obtained from the clinical notes. Results: The median patient age was 54 years (range 31-86 years). Tumour maximum diameter ranged from 1.6-11.3 cm (mean 3.7 cm). Most tumours were of iso-intense signal to muscle on T1-weighted images and hyper-intense to muscle on T2-weighted images. Eighty-eight percent of patients had tumour extending beyond the vagina and 56% of patients had Figo stage III or above tumours. Sixteen patients were treated with radiotherapy (two with chemoradiotherapy), five with surgery and four with supportive care. Ten patients (40%) died of their disease during the study period. The MRI stage of the tumour correlated with survival. Conclusion: MRI identified over 95% of primary vaginal tumours in the present study, enabled radiological staging, which correlated with outcome, and provided information of use in treatment planning.

  5. Malignant biliary obstruction treated with metallic stents

    International Nuclear Information System (INIS)

    Purpose: The outcome of 33 patients with malignant biliary obstruction treated with metallic stents is presented. Materials and methods: Thirty-eight biliary metallic stents were placed in 33 patients with malignant biliary obstruction. They were 52-71 years old (mean = 61.7); 23 were male and 10 were female. The biliary obstruction was caused by biliary carcinoma (n = 16), pancreatic carcinoma (n = 2), hepatoma (n = 2), metastasis in liver (n = 3) and lymph node metastasis (n = 10). Six types and 38 metallic stents were used. After stentering, 3 cases were treated with intrastent brachytherapy, 7 cases treated with external radiotherapy and 2 patients treated with interventional radiology. Patients were followed for 6-28 months, mean 11 months. Results: Stent placement was successful in all 33 cases. The same time, 4 patients were treated with plastic tube for external drainage only. The successful rate was 90%. Twenty-nine patients were placed in one time, 4 cases began with plastic tube which was replaced with metallic stents after 1-2 weeks. Nine had metallic stents and plastic tube, because of complicated obstruction. The external drainage catheters were removed after 15-200 days. Three patients had stents crossing the ampulla. In 28 cases (84.85%), jaundice was reduced satisfactorily while in 5 cases with complicated biliary obstruction, the result was unsatisfactory. The median survival was 7 months. After stentering, 12 cases were treated with locat chemotherapy, brachytherapy or radiotherapy. The median survival period was 10 months. Conclusion: The metallic stent provides good palliative drainage and is well tolerated by patients. It improves the survival rate when combined with radiotherapy, brachytherapy and chemotherapy in patients with malignant biliary obstruction

    A 66-year-old patient was treated with external radiation therapy for an advanced carcinoma of the vulva. Seven years later, a lymphangiosarcoma developed in her edematous lower extremity. Lymphangiosarcomas have been reported to occur in postmastectomy patients; however, this is only the third case in a patient with a gynecologic primary malignancy. In anticipation of possible increased use of radiation therapy in vulvar carcinoma, gynecologists should be aware of this rare, highly aggressive neoplasm.

    @@ Basal cell carcinoma (BCC) is the most common cancer of the skin. However, BCC occurring on non-sun-exposed sites, especially the genital regions such as scrotum and labia, are very rare. An estimated annual incidence of basal cell carcinoma of the scrotum is 1 per 1 000 000 population.1 Here, we report a man with scrotal BCC with the lesion for 51 years, the longest one in the documents. He was successfully treated by circumferential excision.

  11. Multiple basal cell carcinomas arising in a port-wine stain with a remote history of therapeutic irradiation

    International Nuclear Information System (INIS)

    The coexistence of a basal cell carcinoma and a port-wine stain is a very rare condition that may be associated with previous treatments. We present a case of multiple basal cell carcinomas developing within the boundaries of a port-wine stain, which had been treated with a tholium X and argon laser. Our case suggests that port-wine stains which were previously treated with irradiation or argon laser should be examined carefully and regularly by both physician and patient, because they may hide basal cell carcinomas.

    Full Text Available Meningeal metastasis is rare in the clinical course of ovarian carcinoma and its prognosis is extremely poor. We experienced a case of carcinomatous meningitis from metastatic ovarian small cell carcinoma. A 33-year-old woman with atypical genital bleeding, was diagnosed with a right ovarian tumor and referred to our department. She underwent a total abdominal hysterectomy, bilateral salpingo-oophorectomy, omentectomy, and lymphadenectomy. It was an optimal debulking surgery. She was diagnosed with ovarian carcinoma classified as Stage IIIc according to the Féderation Internationale de Gynécologie et d’Obstétrique classification system. Histological findings showed small cell carcinoma of the pulmonary type. The tumor was bilateral with paraaortic lymph node involvement. The patient was treated with irinotecan and cisplatin (CPT-P therapy. After 4 courses of CPTP therapy, multiple liver metastases and Virchow’s lymph node metastases were found. She was treated with amrubicin as a secondline chemotherapy, but the treatment was ineffective. Five months after surgery, the patient complained of severe headache and nausea. Lumbar puncture was performed and cytology was positive. Magnetic resonance brain imaging indicated meningeal thickening. The patient was diagnosed with meningeal metastasis and received 19-Gy whole cranial irradiation. In spite of these treatments, her disease progressed rapidly and she was often drowsy. She died of aspiration pneumonia 6 months after surgery.

    Full Text Available Context Although surgical resection is the only curative therapeutic option for recurrent or metachronous pancreatic carcinomas, most such cancers are beyond surgical curability. We herein report on two rare cases of remnant pancreatectomy used to treat recurrent or metachronous pancreatic carcinomas. Case reports Case#1 A 65-year-old male developed weight loss and diabetes mellitus 83 months after a pylorus-preserving pancreaticoduodenectomy followed by two years of adjuvant chemotherapy (5- fluorouracil plus leucovorin plus mitomycin C for a pancreatic carcinoma in the head of the pancreas (stage IA. An abdominal CT scan revealed a 3 cm tumor in the remnant pancreas which appeared as a ‘hot’ nodule on FDG-PET. A remnant distal pancreatectomy was performed and a pancreatic carcinoma similar in profile to the primary lesion (stage IIB was confirmed pathologically. Case#2 A 67-year-old male showed increased CA 19-9 levels 25 months after a distal pancreatectomy for a pancreatic carcinoma in the body of the pancreas (stage IA. An abdominal CT scan revealed a cystic lesion in the cut end of the pancreas which appeared as a ‘hot’ nodule on FDG-PET. A remnant proximal pancreatectomy with duodenectomy was performed and a metachronous pancreatic carcinoma (stage III was confirmed pathologically. Conclusion Remnant pancreatectomy can be considered a treatment option for recurrent or metachronous pancreatic carcinomas. FDG-PET can play a key role in detecting remnant pancreatic carcinomas.

    2002-01-01

    Objective: To evaluate factors for prognosis of cervical carcinoma. Methods: Expressions of mn23- HI, erbB3 and erbB4 were examined by immunohistochemical staining. The apoptosis was detected in situ by the TdT mediated duip-biotin nick end-labeling (TUNEL) technique. Mitotic cell were counted by HE dyeing. Results: FIGO stage and lymph node metastasis were the most important factors for evaluating prognosis in adenocarcinoma or squamous cell carcinoma. AI/MI was positively correlated with 5-year survival of cervical carcinoma. Positive expression of nm23-H1 combed with negative expression of erbB4 [nm23-H1(+)/erbB4(-)] predicted good prognosis for adeno-carcinoma. In multivariable Cox regression analysis, only FIGO stage and AI/MI were into equation. Conclusion: FIGO stage and AI/MI were independent evaluating parameter for adenocarcinoma or squamous cell carcinoma.

  18. Concurrent Androgen Deprivation Therapy During Salvage Prostate Radiotherapy Improves Treatment Outcomes in High-Risk Patients

    International Nuclear Information System (INIS)

    Purpose: To determine whether concurrent androgen deprivation therapy (ADT) during salvage radiotherapy (RT) improves prostate cancer treatment outcomes. Methods and Materials: A total of 630 postprostatectomy patients were retrospectively identified who were treated with three-dimensional conformal RT. Of these, 441 were found to be treated for salvage indications. Biochemical failure was defined as prostate-specific antigen (PSA) of 0.2 ng/mL or greater above nadir with another PSA increase or the initiation of salvage ADT. Progression-free survival (PFS) was defined as the absence of biochemical failure, continued PSA rise despite salvage therapy, initiation of systemic therapy, clinical progression, or distant failure. Multivariate-adjusted Cox proportional hazards modeling was performed to determine which factors predict PFS. Results: Low-, intermediate-, and high-risk patients made up 10%, 24%, and 66% of patients, respectively. The mean RT dose was 68 Gy. Twenty-four percent of patients received concurrent ADT (cADT). Regional pelvic nodes were treated in 16% of patients. With a median follow-up of 3 years, the 3-year PFS was 4.0 years for cADT vs. 3.4 years for cADT patients (p = 0.22). Multivariate analysis showed that concurrent ADT (p = 0.05), Gleason score (p < 0.001), and pre-RT PSA (p = 0.03) were independent predictors of PFS. When patients were stratified by risk group, the benefits of cADT (hazard ratio, 0.65; p = 0.046) were significant only for high-risk patients. Conclusions: This retrospective study showed a PFS benefit of concurrent ADT during salvage prostate RT. This benefit was observed only in high-risk patients.

  19. Recurrent Syncope due to Esophageal Squamous Cell Carcinoma

    2011-09-01

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

    Objective: To investigate the effect of Celecoxib on proliferation and apoptosis of the endometrial carcinoma cell HEC-1B and the effect on the expression of Fas and Survivin mRNA. Methods: The inhibition on the growth of human endometrial carcinoma cell HEC-1B was investigated by cell culture and MTT experiment when treated with different concentrations of Celecoxib. The cell apoptosis was detected by flow cytometry and DNA Ladder Electrophoresis. The change of the expression of Fas and Survivin mRNA after the treatment of Celecoxib was detected With RT-PCR. Results: Celecoxib could effectively inhibit the growth of HEC-1B cells and induce apoptosis. Survivin mRNA expression was decreased and Fas mRNA expression was increased after treating with Celecoxib. Conclusion: Celecoxib could inhibit HEC-1B cell proliferation and induce its apoptosis.

    2016-08-01

    Upper tract urothelial carcinoma is a disease with rapidly changing management. Though rare, recent multi-institutional collaborations have allowed for study of its biology and treatment outcomes in greater detail than ever before. In coming years physicians treating ureteral cancers will have an expanded armamentarium of treatment options and better data on which to base treatment decisions. Currently there is exciting work underway both in terms of developmental therapies, including neoadjuvant chemotherapy, as well as improved prognostics allowing for better utilization of nephron-sparing approaches where applicable. We present a review of current management techniques and the data on which to base management choices for surgeons treating upper tract urothelial carcinoma. The ultimate goal is improving outcomes for patients; with recent developments and current work in the field, there is reason to be optimistic for the future in this rare, challenging disease.

    Full Text Available Pancreatic cancer patients present late in their course and surgical resection as a modality of treatment is of limited value. Majority develop loco-regional failure and distant metastasis, therefore, adjuvant therapy comprising of radiotherapy and chemotherapy are useful treatment options to achieve higher loco-regional control. Specialized irradiation techniques like intra-operative radiotherapy that help to increase the total tumor dose have been used, however, controvertible survival benefit was observed. Various studies have shown improved median and overall survival with chemoradiotherapy for advanced unresectable pancreatic carcinoma. The role of new agents such as topoisomerase I inhibitors also needs further clinical investigations.

    2012-01-01

    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

  13. Temporal lobe necrosis in nasopharyngeal carcinoma: Pictorial essay

    International Nuclear Information System (INIS)

    Nasopharyngeal carcinoma (NPC) shows a high frequency of skull base erosion and intracranial spread. This tumour is usually treated with radiation therapy. The medial and inferior portions of both temporal lobes are included within the radiation portals. These areas are therefore potential sites of radiation-induced necrosis. It is important to recognize this complication and separate it from intracranial tumour recurrence because the treatments of these entities are different. (authors)

    [Objective] To evaluate the inter-fraction and intra-fraction setup error during the treatment with cone beam computer tomography (CBCT) and provide theoretical basis for clinical target volume-planning target volume (CTV-PTV) margins for nasopharyngeal carcinoma patients treated with volumetric-modulated arc: therapy (VMAT). [Methods] Seventeen consecutive NPC patients treated with VMAT were prospectively enrolled for the study between October 2010 and January 2012. For each patient, three CBCT scans were obtained after conventional positioning, online correction with 2 mm tolerance daily and VMAT delivery weekly, and the scans were registered to the planning CT to determine inter-fraction and intra-fraction errors. The MPTV were calculated with the recipe, Vmurin = 2.5Σ + 0.7σ (Σ, systematic error; σ, random error). [Results] The average absolute errors of the pre-correction, post-correction, and intra-fraction error were 1.1-1.2 mm, 0.6-0.7 mm and 0.4-0.6 mm in the three dimensions. The corresponding X were 0.9—1.3 mm, 0.4—0.5 mm and 0.2-0.4 mm, σ were 0.7-0.9 mm, 0.7 mm and 0.5-0.7 mm. Gradual increases in both inter-fraction and intra-fraction three-dimensional (3D) displacement were observed with time and treatment (P = 0.004, P = 0.009).

    Objective To discuss the clinical feasibility of using 18F - FDG PET/CT imaging to evaluate the prognosis of hepatocellular carcinoma (HCC) that is treated with sorafenib. Methods A total of 40 patients with advanced HCC, who were admitted to authors' hospital during the period from June 2005 to July 2011, were enrolled in this study. All the patients received orally administered sorafenib therapy. Before and after the treatment 18F - FDG PET/CT imaging was performed, the maximum standardized uptake value (SUVmax) of the hepatic lesion was determined, and the therapeutic efficacy was evaluated. The factors affecting the overall survival (OS) time and progress - free survival (PFS) time were analyzed by using multivariable analysis method. Results All the patients were followed up for 2 - 18 months with a median of 9 months. Of the 40 patients, partial response was obtained in 3 and stable disease was seen in 22, and the overall effective rate was 62.5%. The median OS and PFS were 6.1 months (95% CI: 0.0 - 12.0) and 4.8 months (95% CI: 1.4 — 7.2) respectively. The multivariate analysis of OS showed that the following four indices were the independent factors that affected the prognosis: eastern cooperative oncology group (ECOG) performance status, α-fetoprotein concentration, portal vein thrombosis and SUVmax. AFP level and SUVmax were the independent prognostic factors affecting PFS. Based on the optimal critical value of SUVmax (= 5.5), the patients were divided into low SUVmax group (n = 14) and high SUVmax group (n = 26). The values of OS and PFS of the low SUVmax group were significantly higher than those of the high SUVmax group (P = 0.009 and P = 0.003). Conclusion SUVmax determined by 18F-FDG PET/CT imaging is an useful independent prognostic factor for the evaluation of advanced HCC that is treated with orally administered sorafenib therapy.%目的 探讨18F-FDG PET/CT显像评价索拉非尼治疗肝细胞癌预后的可行性.方法 分析2005年6

    Although basal cell carcinoma is the most common skin cancer, it rarely metastasizes. Metastatic basal cell carcinoma may, therefore, initially elude diagnosis and management. We describe the case of a patient with a metastatic basal cell carcinoma present in the lungs. The differential diagnosis of suspected metastatic lesions should include metastases from a cutaneous basal cell carcinoma, in addition to those from more commonly metastasizing carcinomas, especially in patients with a histor...

    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.

Immunohistochemical analysis of carcinomas revealed a strong vitronectin accumulation in extracellular matrix (ECM) around some cancer cell clusters...... and in the subendothelial area of some blood vessels. In normal tissue, vitronectin had a homogeneous periductal occurrence, with local accumulation much lower than that in the carcinomas. Using a new solid phase radioligand assay, the vitronectin concentrations of extracts of carcinomas and normal breast tissue were...... determined and found to be indistinguishable. Comparison of the vitronectin and the hemoglobin concentrations of the extracts showed that their vitronectin content was not derived from blood contamination. Vitronectin mRNA was undetectable in both carcinomas and normal tissue. We conclude that vitronectin...

  4. Conformal radiotherapy of prostate carcinoma: Procedure description

    Full Text Available Introduction. Today, three-dimensional conformal radiotherapy is a standard way in the radical treatment of localized prostate cancer, and it is an alternative to the radical prostatectomy. This method of radiotherapy treatment is widely accepted in the treatment of prostate cancer patients, and provides irradiation of targeted volume (prostate, seminal vesicles with dose escalation sparing the surrounding healthy tissues (rectum, bladder at the same time. That is not possible with the conventional twodimension technique. Procedure description. Three-dimensional conformal radiotherapy is a volumetric, visual simulation according to the computed tomography slices; it defines the tumour and organ at risk individually in each patient. Results of several studies have shown that there is a significant decrease in the development of acute toxicity when prostate cancer patients are treated with conformal radiotherapy. High dose irradiation gives excellent results in treatment of localized prostate carcinoma and improves treatment results in the patients with locally advanced carcinoma of prostate. Discussion. Prostate carcinoma irradiation techniques have been changed dramatically during recent years. Data obtained by computed tomography are important since the size and shapes of the prostate as well as its anatomic relations towards the rectum and bladder are considerably different in individual patients. The three-dimension plan of irradiation can be designed for each patient individually by performing computed tomography technique when planning radiotherapy. Conclusion. The advanced planning systems for conformal radiotherapy can reconstruct the anatomic structures of pelvis in three-dimension technique on the basis of computed tomography scans, which provides better conformality between the irradiation beam and geometrical shape of the tumour with minimal irradiation of the surrounding healthy tissue.

    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.

    BACKGROUND Uterine papillary serous carcinoma (UPSC) is a highly malignant form of endometrial cancer with a high propensity for metastases and recurrences even when there is minimal or no myometrial invasion. It usually metastasizes to the pelvis, retroperitoneal lymph nodes, upper abdomen, and peritoneum. However, adrenal metastases from UPSC is extremely rare. Here, we present a case of UPSC with adrenal metastasis that occurred 6 years after the initial diagnosis. CASE REPORT A 60-year-old woman previously diagnosed with uterine papillary serous carcinoma at an outside facility presented in September of 2006 with postmenopausal bleeding. She underwent comprehensive surgical staging with FIGO (International Federation of Gynecology and Obstetrics) stage 2. Post-operatively, the patient was treated with radiation and chemotherapy. The treatment was completed in April of 2007. The patient had no evidence of disease until July 2009 when she was found to have a mass highly suspicious for malignancy. Subsequently, she underwent right upper lobectomy. The morphology of the carcinoma was consistent with UPSC. She refused chemotherapy due to a previous history of chemotherapy-induced neuropathy. The patient was followed up with regular computed tomography (CT) scans. In October 2012 a new right adrenal nodule was seen on CT, which showed intense metabolic uptake on positron emission tomography (PET)/CT scan. The patient underwent right adrenalectomy. Pathology of the surgical specimen was consistent with UPSC. CONCLUSIONS UPSC is an aggressive variant of endometrial cancer associated with high recurrence rate and poor prognoses. Long-term follow-up is needed because there is a possibility of late metastases, as in this case. PMID:27117594

    AIM: To investigate the inhibitory effects of genistein on metastasis of MHCC97-H hepatocellular carcinoma cells and to explore the underlying mechanism.METHODS: MHCC97-H hepatocellular carcinoma cells were exposed to genistein. A cell attachment assay was carried out in a microculture well pre-coated with fibronectin. The invasive activity of tumor cells was assayed in a transwell cell culture chamber, and cell cycle and apoptosis were evaluated by a functional assay. In addition, the expression and phosphorylation of FAK were detected by Western blotting. In situ xenograft transplantation of hepatocellular carcinoma was performed in 12 nude mice and lung metastasis of hepatocellular carcinoma was observed.RESULTS: Genistein significantly inhibited the growth of MHCC97-H cells in vitro. Adhesion and invasiveness of MHCC97-H cells were inhibited in a concentrationdependent fashion, and the inhibitory effect of genistein was more potent in the 10 μg/mL and 20 μg/ mL genistein-treated groups. Genistein caused G0/G1 cell cycle arrest, an S phase decrease, and increased apoptosis. The expression and phosphorylation of FAK in MHCC-97H cells were significantly decreased. In situ xenograft transplantation of hepatocellular carcinoma was also significantly suppressed by genistein. The number of pulmonary micrometastatic foci in the genistein group was significantly lower compared with the control group (12.3 ± 1.8 vs 16.6 ± 2.6, P < 0.05). CONCLUSION: Genistein appears to be a promising agent in the inhibition of metastasis of hepatocellular carcinoma.

  11. Maxillary sinus carcinoma: Natural history and outcome

    International Nuclear Information System (INIS)

    To assess natural history, treatment outcome and pattern of relapse in patients with maxillary sinus carcinoma. A review was conducted of the medical records of all adult patients with maxillary sinus carcinoma, who were treated at King Faisal Hospital and Research Centre, Riyadh, Kingdom of Saudi Arabia, between January 1990 and December 1999. A total of 60 patients were identified for analysis, 36 men and 24 women; the median age was 58-years (range 23-95). Major presenting symptoms were facial swelling 55%, facial pain 50%, and nasal obstruction 43.4%, with a median duration of 5-months (range 1-24). Histology was quamous cell carcinoma in 71.7% and adenoid cystic in 16.7%. They were restaged according to American Joint Committee on Cancer classification 1997 as II, III and IV in 1, 10 and 49. Thirty patients received treatment with curative intent (surgery in 4 patients, radiotherapy in 2, and combined modality in 24), 6 patients refused treatment and 24 were treated palliatively. With a median follow up of 50-months (range 2-128) in surviving patients treated with a curative intent, 12/30 failed locally, 4/30 in the regional neck nodes and 2/30 had systemic relapse. The actuarial 5-year overall survival (OS), relapse free survival (RFS) and local control rate (LC) were 55%, 39% and 51%. Treatment modality was the only significant prognostic factor for outcome, with 5 year OS, RFS and LC of 72%, 49% and 61%, for combined modality using surgery followed by radiotherapy compared to 0% for single approach (p=0.0003, p=0.0052 and p=0.0098). This study indicates that the majority of our patients presented with advanced disease, resulting in poor outcome to conventional treatment modalities. Efforts should be directed to minimize the delay in diagnosis at the primary care level. Combined modality treatment should be offered to all patients with locally advanced disease. New approaches such as neoadjuvant or concurrent chemoradiotherapy with or without surgery need to

    Thyroglossal duct carcinoma, which is usually diagnosed postoperatively, is a rare malignant tumor arising in the thyroglossal duct cyst. The definitive diag-nosis can be made only after microscopic examination. We retrospectively reviewed three cases of thyroglossal duct carcinoma diagnosed in Peking University School and Hospital of Stomatology from January 1986 to August 2006. Clinical and pathological features were investigated and the optimal treatment protocol was proposed. The constituent ratio of thyroglossal duct car-cinoma among surgically excised thyroglossal duct lesions was 2.9%. The clinical presentation of thyroglos-sal duct carcinoma was very similar to that of its benign counterpart. Two cases were diagnosed as thyroglossal duct cyst prior to the operation, the remaining one as dermoid cyst. All three cases were diagnosed as papillary carcinoma of thyroid origin after microscopic examina-tion. Primary thyroglossal duct carcinoma should con-form to the following criteria: localization of the carcinoma to a clearly demonstrable thyroglossal duct cyst or tract; clinically or histologically confirmed absence of carcinoma of the thyroid gland. Papillary carcinoma is the most common histological type, which usually develops slowly with an excellent Prognosis. The histological characteristics including: formation of pap-illary structure; nuclear morphological variations such as ground glass nuclei, pseudoinclusions, intranuclear grooves and filaments; concentrically calcified struc-tures termed psammoma bodies which is regarded as a strong indication of papillary carcinoma; and positiv-ity in immunohistological staining for thyroglobin. Sistrunk procedure of excision is the choice for treat-ment. A close follow-up is needed. In the presence of thyroid gland masses or cervical lymphadenopathy, thyroidectomy or neck dissection should be recom-mended. The effect of thyroid suppression therapy and radioactive iodine therapy is not conclusive.

    1982-01-01

    Fifteen patients with inoperable squamous cell carcinoma of the vulva were treated with Bleomycin and irradiation. Only 2 patients were also treated with vulvectomy and bilateral lymphadenectomy 2 weeks later. One patient survived more than 4 years without signs of recurrence, another survived 2 1/2 years and 2 more 18 and 12 months respectively. The rest died less than 6 months after the treatment. Three patients developed signs of lung fibrosis. Bleomycin and irradiation may render a tumor operable, but in most cases this regime merely aims at palliation.

    The EGF receptor (EGFR) is expressed in most cases of anal carcinomas. Anecdotal benefit from EGFR-targeted therapy has been reported in anal cancer and a negative correlation with Kirsten Ras (KRAS) mutation status has been proposed. The purpose of this retrospective study was to investigate...... the frequency and the prognostic value of KRAS and BRAF mutations in a large cohort of patients with anal cancer. One hundred and ninety-three patients with T1-4N0-3M0-1 anal carcinoma were included in the study. Patients were treated with curative (92%) or palliative intent (8%) between January 2000...... and January 2010. KRAS mutations were detected using Therascreen(®)KRAS real-time PCR assay (Qiagen) and V600E or V600D/K BRAF mutations were uncovered using Pyrosequencing. The frequency of KRAS and BRAF mutations was low; KRAS mutations were detected in 1.6% and BRAF mutations in 4.7% of the biopsies...

    1982-02-01

    With modern radiotherapy techniques, clinical radionecrosis is uncommon following eradication of primary squamous cell carcinoma from the larynx. Histologic sections from 265 specimens, prepared by the technique of whole organ subserial step-sectioning were studied to determine the incidence and location of chondronecrosis and/or osteomyelitis in both irradiated and non-irradiated cases. Chondronecrosis occurred in only 1 of 41 early (pT1 - pT2) tumors but in 143 advanced tumors (pT - pT4) treated with radical radiotherapy and containing residual carcinoma, 27% had evidence of significant necrosis, compared with 24% of those not irradiated. Age, sex, tumor grade and previous laryngeal surgery did not appear to be significant factors in the development of necrosis in irradiated patients. The arytenoid cartilage was most frequently involved when chondronecrosis occurred in association with radiotherapy. Six total laryngectomy specimens (3%) were received from patients with symptoms of chondronecrosis and in whom no residual tumor was present. We conclude that although the incidence of clinical perichondritis is low, histologic chondronecrosis and/or osteomyelitis occurred in 26% of all the larynges studied. Radiotherapy appears to be a significant causative factor only in advanced supraglottic tumors.

    Full Text Available Spindle cell carcinoma (SpCC is a unique variant of squamous cell carcinoma (SCC. SpCC confined to the nasal cavity is extremely rare, with only one case having been previously reported. We present a case report of nasal cavity SpCC and review the literature on this rare entity. A 29-year-old male presented with intermittent epistaxis from the left nasal cavity. On physical examination, the patient had an ulcerated mass in the left nasal vestibule and a biopsy showed a proliferation of spindle and epitheliod cells. The patient underwent wide local excision of the mass via a lateral alotomy approach and reconstruction with a composite conchal bowl skin and cartilage graft. Histologically, the mass had dyplastic squamous epithelium and spindle-shaped cells admixed with epitheliod cells. Immunohistochemistry was only positive for pancytokeratin AE1/AE3 and vimentin. Six months after surgery, the patient continues to have no evidence of disease. On literature review, only one previous case of SpCC confined to the nasal cavity was identified. We present a rare case of nasal cavity SpCC. No definite treatment protocol exists for this unique entity, but we believe that this tumor should primarily be treated with aggressive, wide local excision. Adjuvant radiation and/or chemotherapy have also been used anecdotally.

    International Nuclear Information System (INIS)

    A 69-year-old white Italian woman was first seen at Memorial Sloan-Kettering Cancer Center in 1981 concerning several skin growths on her back. The patient had had several basal cell carcinomas surgically removed from her back during the preceding 5 years. There was no history of arsenic ingestion or prolonged sun exposure and her family history was negative for skin cancer. The patient had developed pulmonary tuberculosis in 1938 and was treated with pneumothorax therapy. She had had more than 50 fluoroscopic examinations of the chest following this therapy, as well as multiple diagnostic x-ray films since that time. On the back, clustered in the interscapular region, were multiple scars and nine erythematous nodules with pearly borders, telangiectasia, and translucent surfaces. Within several nodules there were areas of light and dark brown pigmentation. Biopsy of all lesions revealed basal cell carcinoma, some of which were pigmented, without evidence of chronic radiodermatitis. All lesions were treated with curettage and electrodesiccation three times with good cosmetic results

    From 1967 through 1985, 358 cases of early glottic carcinoma were treated with telecobalt therapy at the Department of Radiology, Osaka University Medical School. Among 278 cases treated with 2 Gy a day, the tumor response of 262 cases at 40, 50 and 60 Gy were evaluated by direct or indirect laryngoscope. The five-year local control rates of these evaluable cases of T1 and T2 glottic carcinoma were 79% and 70%, respectively. The local control rates of T1 glottic carcinoma with tumor clearance and persistence at 40 Gy were 83% (119/143) and 64% (43/67), and those of T2 cases were 86% (18/21) and 58% (18/31), respectively. The local control rates of the cases with tumor clearance and persistence at 40 Gy were same between T1 and T2 cases. The tumor clearance rates of T1 cases were significantly higher than those of T2 cases (p<0.005). T2 glottic carcinoma had larger tumor volumes and slower tumor regression and resulted in lower control rates compared with T1 glottic carcinoma. The difference in the radiation dose of T1 and T2 glottic carcinoma with the same clearance rate was estimated as 15 Gy using logit analysis. (orig.).

    Salivary gland myoepithelial carcinoma (MC) or malignant myoepithelioma is a rare entity. MC usually presents as a slow-growing painless mass arising in the parotid gland, but may involve other salivary glands. This tumour may be particularly locally aggressive, but its clinical and biological features are not yet fully understood. MC may arise from pre-existing benign lesions, such as pleomorphic adenomas or benign myoepitheliomas, or may arise de novo. It usually affects patients over 50 years old, with no gender preference. Because it is often asymptomatic, the presentation and diagnosis can be delayed by months, even years. The current WHO classification considers MC to be an intermediate- to high-grade malignancy. Other published data suggest it is likely to be a high-grade neoplasm, consistent with its aggressive behaviour. Its epidemiology, histopathological features, immunohistochemical profile, clinical behaviour and optimal management are not well understood. Following review of the current literature we aim to address these.

  3. Carcinoma of the vulva

    International Nuclear Information System (INIS)

    The accepted primary treatment modality in carcinoma of the vulva is a surgical resection. The standard approach is a radical vulvectomy with superficial nodal dissections if the superficial ignuinal nodes are involved. Surgical treatment is associated with a substantial incidence of local recurrence and significant morbidity predominantly associated with nodal dissection. Definitive radiation therapy is a viable alternative to surgery; with it, an overall 5-year survival of 40% to 50% can be expected. The incidence of sequelae with definitive radiation therapy appears acceptable, and is conceivable that it might be reduced substantially if modern techniques and time-dose schemes are applied. A promising area for radiation therapy is in combination with surgery

    A 92-year-old man presented for evaluation with a 1-month history of a rapidly growing asymptomatic pink nodule on his forearm. Biopsy results of the lesion demonstrated pathology consistent with Merkel cell carcinoma (MCC). Immunohistochemical studies displayed positive cytoplasmic staining for cytokeratin AE1/AE3, positive dot-like perinuclear staining for cytokeratin-20, diffuse cytoplasmic staining for neuron specific enolase, and no significant staining for S-100. Subsequent positron emission tomography did not reveal evidence of metastatic disease. Wide excision of the lesion was performed along with a sentinel node biopsy of his left axilla. The sentinel nodes were negative for MCC. Adjuvant radiation treatment of the tumor site was provided because the pathologist noted MCC within 2 mm of the deep margin. PMID:24933855

  5. Hepatocellular Carcinoma (HCC)

    Helmberger, Thomas K.

    Hepatocellular carcinoma (HCC) is considered to be one of the most common malignancies worldwide, and the most common one in Africa and Asia. Over the last decade, a rising incidence of up to 10-15/100,000 per population has been seen in the Western world, with an estimate of 250,000 deaths and more than a million worldwide per year. By the year 2010, the World Health Organization expects that HCC will be the leading cause of cancer mortality surpassing lung cancer. This increasing incidence is most likely related to an increasing prevalence of chronic hepatitis C (HC) and B (HB) virus infections and other diseases inducing chronic inflammation (Befeler and Di Bisceglie 2002; Llovet et al. 2003).

    The completely assembled human genome has made it possible for modern medicine to step into an era rich in genetic information and high-throughput genomic analysis. These novel and readily available genetic resources and analytical tools may be the key to unravel the molecular basis of hepatocellular carcinoma (HCC). Moreover, since an efficient treatment for this disease is lacking, further understanding of the genetic background of HCC will be crucial in order to develop new therapies aimed at selected targets. We report on the current status and recent developments in HCC genetics. Special emphasis is given to the genetics and regulation of major signalling pathways involved in HCC such as p53, Wntsignalling, TGFβ, Ras, and Rb pathways. Furthermore, we describe the influence of chromosomal aberrations as well as of DNA methylation. Finally, we report on the rapidly developing field of genomic expression profiling in HCC, mainly by microarray analysis.

    We report a case of dermatomyositis associated with prostatic carcinoma. A 69-year-old male was admitted to the Department of Internal Medicine with the chief complaint of general fatigue, appetite loss and facial anthema. Abdominal ultrasound demonstrated swollen periaortic lymph nodes and the margin of prostate was unclear. Prostatic carcinoma was suspected based on digital rectal examination, so he was admitted to our department. Serum prostate specific antigen level was 190 ng/ml. He was examined by a dermatologist because of deterioration of anthema. Dermatomyocitis was demonstrated by dermatoses (edema erythema at face, neck and limbs, nail fold thrombosis and poikiloderma), high serum level of creatine phosphokinase and a decrease in muscular strength (especially at the proximal musculus). There was no interstitial pneumonitis or malignancy of the digestive system. On needle biopsy of the prostate and quadriceps femoris muscle, prostatic carcinoma (poorly differentiated adenocarcinoma, Gleason score 5 + 5) and myositis were suspected. The stage of prostatic carcinoma was T4N1M1. The patient was treated by administration of diethylstilbestrol phosphate and prednisolone for prostatic carcinoma and dermatomyositis, respectively, but he died of multiple metastasis of the tumor 1 year and 5 months later. Dermatomyocitis is associated with malignancy more frequently than any other collagen disease. In Japan, it is frequently complicated by gastric, lung and mammory cancers, but rarely by prostatic carcinoma. To our knowledge, this is the fourth case of prostatic carcinoma associated with dermatomyocitis in Japan. PMID:15101164

    Full Text Available Carcinoma of the cervix is the most common malignancy among women in India. Although metastatic disease is common, metastasis to breast is rare. A limited number of case reports are published in the world literature. Most of the previous reports of metastatic cervical carcinoma to breast are either autopsy series or widely disseminated disease where no treatment options were available. A rare case of cervical carcinoma presenting as metastasis in breast is reported here where palliative mastectomy improved the general condition of the patient. A female patient aged 58 years was diagnosed and treated for cervical carcinoma, FIGO stage 2B. Four months after the treatment which included both external beam and intracavitory radiotherapy, the patient presented with breast and lung metastasis. Palliative mastectomy was done which improved the general condition of the patient. Metastatic carcinoma of the cervix can present as a case of breast carcinoma. In an appropriate setting, this possibility should be kept in mind. Palliative mastectomy should be offered for patients of cervical carcinoma with metastasis to breast when needed.

    Full Text Available BACKGROUND Incidence of carcinoma larynx in India reported to be 1.3 to 8.8 per 100,000 populations in six different regions of the country. The main risk factors for development of carcinoma larynx are consumption of smoke tobacco and alcohol. The aim of this study was to evaluate clinico-pathological parameters in patients with carcinoma larynx. MATERIAL AND METHOD A total of 110 patients newly diagnosed with carcinoma larynx were included in this study after taking informed consent from the patient and clearance from the ethics committee. Previously treated larynx cancer patients with recurrence were excluded. RESULT Pain on swallowing was the commonest presenting symptom present in 101 (91.81% patients. Smoke tobacco consumption was present in 104 (94.54% patients, smokeless tobacco consumption was present in 12 (10.90% patients and alcohol consumption was present in 94 (85.45% patients with cancer larynx. Most of the patients had inadequate dietary intake as per recommended dietary allowance. CONCLUSIONS The most common site involved was supraglottis seen in 70 (63.63% patients. Most of the patients presented with stage III cancer in 43 (39.09% patients. Squamous cell carcinoma was the histopathological variant seen in all patients in our study. Moderately differentiated squamous cell carcinoma was the most common squamous cell carcinoma variant seen present in 62 (56.36% patients.

    -B-containing isoform and the oncofetal FN isoform derived by O-glycosylation, in oral squamous cell carcinomas, premalignant lesions, and normal oral mucosa. A selective expression of the ED-B-containing isoform was demonstrated in close relation to the invading carcinoma (38/38), whereas there was virtually...... no staining in submucosa underlying premalignant lesions (1/11) and normal epithelium (0/5).

These results demonstrate that accumulation of FN adjacent to oral carcinomas includes...... both the ED-B-containing isoform and the isoform derived by O-glycosylation. Although both the change in primary structure and glycosylation of FN create conformational and immunologically detectable changes, the functional consequences in association with invasive carcinoma are poorly understood...

    We submit the case of a child afflicted with a mucoepidermoid bronchial tumor. The patient is a boy, aged seven, who after undergoing antibiotic treatment for six weeks because of a fever and atelectasia-condensation in the right lower lobe showed no signs of clinical improvement and was sent to our department to undergo further study and treatment. A bronchoscopy performed shows a polypoid mass that partially blocks the main bronchial tube a few milimiters under the access to the right upper lobe. A biopsy is carried out and the anatomopathological test shows there is a low degree epidermoid carcinoma. We decide to perform a lobectomy which for the tumor location and the lung condition has to be medium and lower right. We proceed to remove the adenopaty of hilium not affected by the tumor. The postoperative period develops without incidents. A check-up bronchoscopy performed three months later shows two polypoid masses in the right bronchial tube which, once a biopsy is performed, proved to be granulation tissue. Twelve months after undergoing surgery, the patient's condition is good, there is no evidence of tumor relapse and the breathing capacity is adequate, though there is an obstructive restrictive pattern in the espirometry. Even taking into consideration that lung tumors are extremely unusual, the epidermoid carcinoma is the one which most frequently occurs. The tumor's low malignancy is a sign that points to a good prognosis. Performing conservative surgery by means of bronchoplasty should be taken into account so as to keep the sequelae on the lung condition to a minimum, even though in this case the tumor location made it impossible.

    Breast cancer is a heterogeneous disease that encompasses a wide range of histopathological types including: invasive ductal carcinoma, lobular carcinoma, medullary carcinoma, mucinous carcinoma, tubular carcinoma, and apocrine carcinoma among others. Pure apocrine carcinomas represent about 0...... benign apocrine changes and breast carcinoma is unclear and has been a matter of discussion for many years. Recent proteome expression profiling studies of breast apocrine macrocysts, normal breast tissue, and breast tumours have identified specific apocrine biomarkers [15-hydroxyprostaglandin...... dehydrogenase (15-PGDH) and hydroxymethylglutaryl coenzyme A reductase (HMG-CoA reductase)] present in early and advanced apocrine lesions.

    A case of an 82-year-old female with primary laryngeal cryptococcosis who had undergone long-term corticosteroid therapy for chronic obstructive pulmonary disease and rheumatoid arthritis is reported. She complained hoarseness with swallowing pain and irritability of the larynx for over a month. Endoscopic examination revealed a white, exudative irregular region on right arytenoid that mimicked a laryngeal carcinoma. Histological examination showed pseudoepitheliomatous hyperplasia and severe submucosal inflammation with ovoid budding yeasts by Grocott's stain. A serological study indicated a high titer of cryptococcal antigen. After treating with oral fluconazole for 3 months, her primary lesion of larynx turned to be clear. We implicate a long-term use of steroids as the significant risk factor in developing cryptococcosis of the larynx.

    2014-11-01

    We reported 1 case of salivary duct carcinoma (SDC) in the mandible. The patient complained of pain and a growing mass in the right submandibular area for approximately 2 months. On clinical examination, there was a mass under the right angle of the mandible with a size of approximately 3 × 3 cm, a smooth surface, a poor activity, and a hard texture. Panoramic radiograph revealed poorly circumscribed area. Computed tomography presented mandible central destruction. Biopsy examination showed a malignant tumor that originated in the central epithelium of the mandible. An operation of unilateral selective neck dissection and mandible subtotal ectomy was performed. Postoperative pathology reported SDC. The patient received postoperative radiation and stayed alive at last follow-up without disease recurrence. Ablative resection and postoperative radiotherapy were the standard treatment stratagem for SDC, but trastuzumab therapy might play a key role in treating the disease in future. PMID:25377985

    Hepatocellular carcinoma (HCC) is an aggressive liver tumor that occurs with chronic liver disease. Surgical resection is the mainstay of therapy for localized disease whereas therapeutic options for advanced disease are limited. The innovative blockade of immune checkpoints with targeted immunotherapies, such as monoclonal antibodies against programmed death receptor 1 (PD-1), have shown promise in the treatment of solid malignancies. The PD-1 inhibiting antibodies, nivolumab and pembrolizumab prolonged overall survival in randomized trials in metastatic melanoma and advanced non-small cell lung cancer. This is a report of a 75-year-old male patient with metastatic HCC who was initially treated with the standard of therapy sorafenib. After failure of sorafenib therapy, pembrolizumab was started. There was a dramatic response to pembrolizumab with decrease in tumor size and drop in alfa fetoprotein. To the best of our knowledge, this is the first case report of metastatic HCC responsive to pembrolizumab after failure of sorafenib.

    2003-01-01

    Hepatocellular carcinoma (HCC) is one of the most commonmalignancies in the world, responsible for an estimated one million deaths annually. It has a poor prognosis due to its rapid infiltrating growth and complicating liver cirrhosis.Surgical resection, liver transplantation and cryosurgery are considered the best curative options, achieving a high rate of complete response, especially in patients with small HCC and good residual liver function. In nonsurgery, regional interventional therapies have led to a major breakthrough in the management of unresectable HCC, which include transarterial chemoembolization (TACE), percutaneous ethanol injection (PEI), radiofrequency ablation (RFA), microwave coagulation therapy (MCT), laser-induced thermotherapy (LITT), etc. As a result of the technical development of locoregional approaches for HCC during the recent decades,the range of combined interventional therapies has been continuously extended. Most combined multimodal interventional therapies reveal their enormous advantages as compared with any single therapeutic regimen alone,and play more important roles in treating unresectable HCC.

    Renal cell carcinoma presents several unique features, which distinguish it from other tumours. The increase in survival that has been described in patients with renal cell carcinoma following nephrectomy breaks a classical rule of oncology, which states that surgery of the primary tumour has no role in the treatment of patients with advanced disease. Together with melanoma, it is the only tumour in which immunomodulatory treatments with drugs such as interleukin-2 produces a clinical benefit...
