  1. Biological (DB) and internal dosimetry (DI) in patients with differentiated thyroid carcinoma (CaDT) treated with iodine 131

    International Nuclear Information System (INIS)

    The internal 131I radiotherapy in patients with CaDT is used within the therapeutic scheme as a step post-thyroidectomy. The success of therapy is to achieve a lethal dose in the tumor tissue without exceeding the dose of tolerance in healthy tissues (doses greater than 2 Gy in bone marrow could lead to myelotoxicity). In this work, the treatment protocol applied incorporates assessment by biological (DB) and internal dosimetry (DI) for estimating doses to the whole body and bone marrow to administer a therapeutic personalized for each patient. The estimate biological dose is based in the quantification of chromosomal aberrations, which is referred to a dose-response curve. Objectives: 1) To estimate the absorbed dose to the whole body and bone marrow due to the administration of 131I therapy in patients with CaDT, by applying three different cytogenetic tests: conventional cytogenetics, micronuclei (MN) and fluorescence in situ hybridization (FISH); 2) Assess the correlation of the results obtained by DB and DI for personalization of treatment. Materials and methods: We evaluated 24 patients with CaDiT by applying the cytogenetic tests mentioned and internal dosimetry (methodology Mird-Olinda). Internal dosimetry: We administered a tracer dose 74 to 111 MBq. Measurements were made of activity in whole body and blood. By adjusting the scheme was estimated MIRD dose in bone marrow and the maximum therapeutic activity to manage and secure. Through software Olinda was determined absorbed dose to the whole body for each patient. We considered patient-specific data (physical frame size, weight, hematocrit) to adjust the methodology in each particular case. It is assumed that the tracer activity administered has a kinetic in the body similar to the 131I to be administered in therapeutic amounts. Biology Dosimetry : We performed for each patient taking 2 sequential venous blood samples to estimate the dose due to therapeutic activity in review: the first shows, pre

  2. 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....

    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.

    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.

    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.

  9. Improved outcome of nasopharyngeal carcinoma treated with conventional radiotherapy

    International Nuclear Information System (INIS)

    Purpose: To describe the outcome of patients with nonmetastatic nasopharyngeal carcinoma (NPC) treated with conventional radiotherapy at a single institution. Methods and materials: From 1990 to 1999, 171 consecutive patients with NPC were treated with conventional (two-dimensional) radiotherapy. Tumor histology was undifferentiated in 82% of cases. Tumor-node-metastasis Stage (American Joint Committee on Cancer/International Union Against Cancer 1997 system) was I in 6%, II in 36%, III in 22%, and IV in 36% of patients. Mean total radiation dose was 68.4 Gy. Chemotherapy was given to 62% of the patients. The median follow-up for surviving patients was 6.3 years (range, 3.1-13.1 years). Results: The 5-year overall survival, disease-specific survival, and disease-free survival rates were 72%, 74%, and 62%, respectively. The 5-year local, regional, and distant control rates were 84%, 80%, and 83% respectively. Late effects of radiotherapy were prospectively recorded in 100 patients surviving without relapse; 44% of these patients had Grade 3 xerostomia, 33% had Grade 3 dental damage, and 11% had Grade 3 hearing loss. Conclusions: This analysis shows an improved outcome for patients treated from 1990 to 1999 compared with earlier retrospective series, despite the use of two-dimensional radiotherapy. Late toxicity, however, was substantial with conventional radiotherapy

  10. 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

    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

    Incidental papillary carcinoma of the thyroid in patients treated surgically for benign thyroid diseases including Graves' disease is a known phenomenon. However, the management of these patients remains an issue of concern and controversy for those who care for them. We report a case of metastatic papillary carcinoma of the thyroid in a patient previously treated for Graves' disease. The subject of this presentation is a 50-year-old lady who was diagnosed with Graves' disease at the age of 29, for which she had a subtotal thyroidectomy following failure of medical and radioactive iodine treatment. Three years later, the patient was referred to our nuclear medicine department with a clinical diagnosis of suspected metastatic lymph nodes presumably from a thyroid malignancy.She had an 123I diagnostic whole body scan that showed 123I avid areas in the thyroid bed as well as left cervical lymph nodes, which later turned out to be metastatic papillary carcinoma of the thyroid on histology. She was treated with therapeutic doses of 131I. Follow-up radioactive iodine scans and serum thyroglobulin assays showed no evidence of malignant thyroid tissue. The occurrence of papillary carcinoma of the thyroid after a subtotal thyroidectomy for Graves' disease is hereby reported. The need for vigilance and regular follow-up in patients who receive all forms of treatment for benign thyroid diseases is emphasized. PMID:24705115

  2. Carcinoma of the maxillary antrum treated by pre-operative radiotherapy or radical radiotherapy alone

    International Nuclear Information System (INIS)

    The results of pre-operative radical radiotherapy and subsequent maxillary resection are reported in 54 consecutive patients with carcinoma of the maxillary antrum treated at The Royal London Hospital from 1965 to 1989. The actuarial two and five year survivals were 50.3 per cent and 38.5 per cent respectively. Patients with adenocarcinomas fared better when compared with squamous and undifferentiated carcinomas (log rank p = <0.01). Undifferentiated carcinoma and involved regional lymph nodes were both very poor prognostic factors. In those patients who were either unfit for or refused maxillary resection, radical radiotherapy alone was still an effective treatment, with only a slight disadvantage in terms of local control and survival.

    Background Papillomatosis presents, most frequently, as multiple lesions of the respiratory tract, which are usually considered benign. 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.

    Renal cell carcinoma is a rare pediatric malignant tumor of the kidney. Unlike Wilms tumor, the efficacy of chemotherapy and radiation therapy in pediatric renal cell carcinoma remains uncertain. Surgery is the best treatment and prognosis is favorable when the tumor is localized and completely eradicated. We report an exceptional observation in a 7-year-old girl with renal cell carcinoma who had been treated 20 months previously for Ewing sarcoma with chemotherapy and radiotherapy. The renal tumor was revealed by abdominal pain without hematuria. She underwent a radical nephrectomy, and histopathology concluded in renal carcinoma associated with translocation Xp 11.2 grade 3 of Furhrman pT3a N1. No adjuvant therapy was given. After 3 years of follow-up, there is no evidence of local or metastatic recurrence. This observation is significant given the very young age of this patient, the occurrence after Ewing sarcoma with a short disease-free interval. It seems that translocation renal cell carcinoma is associated with previous exposure to chemotherapy, particularly topoisomerase II inhibitors or alkylating agents. PMID:26702489

    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.

  9. 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

  10. Risk stratification of patients with advanced squamous cell carcinoma of cervix treated by radiotherapy alone

    International Nuclear Information System (INIS)

    Purpose: To identify prognostic factors for local and distant relapse and perform risk stratification for patients with advanced cervical cancer treated with radiotherapy (RT) alone. Methods and Materials: A total of 1031 patients with Stage IB-IVA squamous cell carcinoma of the cervix treated with full-course RT but without any chemotherapy were included for analysis. Of these, 311 patients with nonbulky Stage IB-IIA disease were designated the reference group and the other 720 patients were the study group. The associations of stage, squamous cell carcinoma antigen (SCC-ag) level, hemoglobin level, age, cell differentiation, and pelvic lymph node status with treatment failure were evaluated. The independent prognostic factors were identified by multivariate analysis. The study group was further stratified into subgroups using combinations of these risk factors. Results: In the study group, independent risk factors for local relapse were advanced stage and age 2, and positive pelvic lymph nodes. The 5-year distant relapse-free survival rate was 83% for patients with bulky Stage IB-IIA and IIB disease, SCC-ag level 2, and positive lymph nodes. Conclusion: The risk of treatment failure in advanced-stage cervical cancer patients treated by RT alone can be more precisely predicted by risk stratification. A certain subgroup of patients had better control than the others. The benefit of treating these relatively low-risk patients with additional treatment such as concurrent chemotherapy should be further evaluated in prospective studies or meta-analyses

    Full Text Available Basal cell carcinoma (BCC is the most common skin cancer worldwide. Surgical excision is considered to be the primary therapeutic modality wherever possible. For inoperable cases, 5% imiquimod seems to be a good alternative. We present two cases of nodular pigmented BCCs on the face in elderly women successfully treated with 5% imiquimod cream application resulting in complete clinical clearance of lesion as well as on histology and dermatoscopy. There was no recurrence of the lesion on 2 years follow-up for the first and 1.5 years for the second patient.

    International Nuclear Information System (INIS)

    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)

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

    High grade neuroendocrine carcinomas (HGNEC) treated by cystectomy often carry an original diagnosis of typical urothelial carcinoma (UC). The correct diagnosis of HGNEC is critical in influencing the decision for early chemotherapy, potentially followed by cystectomy. The objective of this study was to characterise the features of HGNEC treated by radical cystectomy. The study consisted of 79 patients with HGNEC including small cell (68 patients), large cell neuroendocrine (LCNEC) (5 patients) and mixed neuroendocrine (mixed-NEC) carcinoma (6 patients) matched with 122 patients with UC, treated at our institution between 1987 and 2014. Morphometric analysis for cell and nuclear size as well as immunophenotyping for neuroendocrine markers and cell-cycle regulators were applied to tissue microarrays. Small cell, LCNEC and mixed-NEC are a morphological spectrum of high grade neuroendocrine carcinoma with overlapping histological features, identical immunophenotype, Ki-67 proliferative rate and patient outcomes. Finally, the nuclear size criteria is misleading as HGNEC, particularly cases of LCNEC and mixed-NEC, may have enlarged nuclei compared to small cell carcinomas and are more prone to be misdiagnosed as UC, thereby preventing appropriate management.

    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.

    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.

    Full Text Available Lei Yu,1 Yun Jing,2 Shan Ma,1 Fei Li,1 Yun-Feng Zhang11Department of Thoracic Surgery, 2Department of Neurology, Beijing Tongren Hospital, Capital Medical University, People’s Republic of ChinaBackground: The treatment of thymoma or thymic carcinoma with pleural dissemination remains controversial due to the unpredictable natural history of this tumor. Our study discusses the combination of cytoreductive surgery with hyperthermic intrapleural chemotherapy to treat thymoma or thymic carcinoma with pleural dissemination.Methods: From February 2008 to January 2010, there were four patients with pleural thymoma metastases undergoing cytoreductive surgery and intrathoracic hyperthermic perfusion with chemotherapy at our department. After video-assisted thoracoscopic surgery, the hyperthermic perfusion system was set up for hyperthermic intrapleural chemotherapy. The thoracic cavity was perfused at a speed of approximately 1.8–2.3 L/min with 0.9% normal saline. The intrathoracic temperature remained between 42°C and 43°C. The perfusion process lasted for 2 hours.Results: There were no perioperative deaths. During the hyperthermic perfusion, the patient's core temperature varied from 36.3°C and 39.3°C and pulse varied from 59 beats/min and 126 beats/min. Intraoperative sinus tachycardia occurred in two elderly patients. No hematologic toxicity and nephrotoxicity was observed within 1 week after surgery. Postoperative pneumonia occurred in one elderly patient. Patients were followed up for 1–4 years. One elderly patient died of heart failure 1 year after surgery. There were no patients with local recurrence or metastases to distant sites.Conclusions: Cytoreductive surgery and intrathoracic hyperthermic perfusion with chemotherapy may be effective in treating thymoma or thymic carcinoma with pleural dissemination and has an encouraging impact on the patients’ long-term survival.Keywords: thymoma, pleural dissemination, surgery, hyperthermia

  4. Imaging followup in patients with unresectable hepatocellular carcinoma treated with conventional transarterial chemoembolisation

    International Nuclear Information System (INIS)

    Full text: Background: Hepatocellular carcinoma (HCC) represents more than 5% of all neoplasms and is the most frequent cause of mortality in patients with cirrhosis. Although a number of therapeutic options are available, transarterial chemoembolisation is widely used in the treatment of unresectable HCC. Aim: Evaluation of the role of CT and MRI exams in the imaging followup of patients with unresectable hepatocellular carcinoma treated with conventional transarterial chemoembolisation (TACE). Materials and methods: We retrospectively reviewed 120 consecutive patients with the diagnosis of HCC, sent to the Department of Radiology, Medical Imaging and Interventional Radiology between january 2011 and april 2012 for TACE. The diagnosis of HCC was established using imaging criteria and elevated alfafetoprotein levels (higher than 400ng/ml) or histologic diagnosis. After the procedure, the imaging followup algorithm consisted in an ultrasound exam 24 hours after the procedure, a CT exam 1 month, a MRI exam 3 months later (if the previous CT showed no tumoral residues) and a CT exam 6 months later. The tumoral response was evaluated using the modified RECIST criteria (tumoral dimensions defined as the product of the 2 largest diameters), the visualisation of tumoral arterial enhancement and the presence of intratumoral lipiodol accumulation (defined as absent, homogenous or heterogenous). Results: At the CT exam performed 1 month after the procedure, 44 patients (37%) had homogenous intratumoral lipiodol accumulation, without any tumoral residues and with dimensional reduction. In patients with tumoral residue (n=76), the intratumoral lipiodol accumulation was homogenous (n=48) or heterogenous (n=28); in 5 cases, after the first TACE procedure, we had no lipiodol accumulation in the target lesion. Conclusion: CT exam is an essential tool in the post procedural followup in patients with unresectable hepatocellular carcinoma treated with conventional transarterial

  5. Long-term outcome of patients treated by radiation therapy alone for salivary gland carcinomas

    International Nuclear Information System (INIS)

    Purpose: To review a single-institution experience with the management of salivary gland cancers treated by radiation alone. Methods and Materials: Between 1960 and 2004, 45 patients with newly diagnosed salivary gland carcinomas were treated with definitive radiation to a median dose of 66 Gy (range, 57-74 Gy). Distribution of T-stage was: 24% T1, 18% T2, 31% T3, and 27% T4. Histology was: 14 mucoepidermoid (31%), 10 adenocarcinoma (22%), 8 adenoid cystic (18%), 4 undifferentiated (9%), 4 acinic (9%), 2 malignant mixed (4%), 2 squamous (4%), and 1 salivary duct carcinoma (2%). No patient had clinical or pathologic evidence of lymph node disease. Median follow-up was 101 months (range, 3-285 months). Results: The 5-year and 10-year rate estimates of local control were 70% and 57%, respectively. A Cox proportional hazard model identified T3-4 disease (p = 0.004) and radiation dose lower than 66 Gy (p = 0.001) as independent predictors of local recurrence. The 10-year overall survival and distant metastasis-free rates were 46% and 67%, respectively. Conclusion: Radiation therapy alone is a reasonable alternative to surgery in the definitive management of salivary gland cancers and results in long-term survival in a significant proportion of patients. Radiation dose in excess of 66 Gy is recommended

  6. Nasopharyngeal carcinoma treated with facial cervical portal and late-course hyperfractionation radiotherapy

    International Nuclear Information System (INIS)

    Objective: To evaluate the clinical results and side reactions of nasopharyngeal carcinoma (NPC) treated with facial cervical portal and late-course hyperfractionation radiotherapy. Methods: From July 1996 to December 1997, 93 NPC patients were divided into conventional fractionation and hyperfractionation radio- therapy groups. In 47 patients, facial cervical portal was used until the dose of 36 Gy/20 fraction in 4 weeks, and then followed by hyperfractionation radiotherapy: 1.15-1.2 Gy/fraction, 2 fraction/day, with 6-8 hour interval between, to a total dose of 74.2-76.7 Gy in 7.5 weeks without changing the shape of the portal. Forty-six patients were treated by conventional radiotherapy: 2.0 Gy/fraction, 5 fraction/week, to a total dose of 69-72 Gy in 7.5 weeks. Results: The regression rate was 100%, 96% in hyperfractionation and conventional fractionation radio-therapy group after 6 months of radiotherapy, respectively. The 1-, 3-, and 5-year local control rate was 100%, 98%, 86% in the hyperfractionation radiotherapy group and 98%, 86%, 54% in the conventional fractionation group (P0.05). Conclusions: In nasopharyngeal carcinoma, the local control rate and survival rate are raised by hyperfractionation radiotherapy. But recurrence rate and distant metastasis rate are not significantly different. (authors)

  7. High survivin expression as a risk factor in patients with anal carcinoma treated with concurrent chemoradiotherapy

    International Nuclear Information System (INIS)

    To investigate the prognostic value of survivin expression in pretreatment specimens from patients with anal cancer treated with concurrent 5-FU and mitomycin C-based chemoradiation (CRT). Immunohistochemical staining for survivin was performed in pretreatment biopsies of 62 patients with anal carcinoma. Survivin expression was correlated with clinical and histopathological characteristics as well as local failure free- (LFFS), distant metastases free- (DMFS), cancer specific- (CSS), and overall survival (OS). Survivin staining intensity was weak in 10%, intermediate in 48% and intense in 42% of the patients. No association between survivin expression and clinicopathologic factors (tumor stage, age and HIV status) could be shown. In univariate analysis, the level of survivin staining was significantly correlated with DMFS (low survivin vs. high survivin: 94% vs. 74%, p = 0.04). T-stage, N-stage and the tumor grading were significantly associated with OS and CSS and with DMFS and LFFS, respectively. In multivariate analysis, survivin was confirmed as independent prognostic parameter for DMFS (RR, 0.04; p = 0.02) and for OS (RR, 0.27; p = 0.04). Our results demonstrated that the level of pretreatment survivin is correlated with the clinical outcome in patients with anal carcinoma treated with concurrent CRT. Further studies are warranted to elucidate the complex role of survivin for the oncologic treatment and to exploit the protein as a therapeutic target in combined modality treatment of anal cancer

  8. Carcinoma of the nasopharynx treated by radiotherapy alone: determinants of distant metastasis and survival

    International Nuclear Information System (INIS)

    Purpose: This retrospective study was conducted to identify the prognostic factors for distant metastasis and survival in a population of 378 patients with nasopharyngeal carcinomas treated by radiation therapy alone. Materials and methods: All patients were treated at the University of Texas M.D. Anderson Cancer Center between 1954 and 1992, following a consistent dose and volume prescription policy. There were 286 males and 92 females. The median age was 52 years (range: 16-86 years). The majority of the patients were white Caucasians (282 patients, 75%). Tumors were classified as squamous cell carcinomas (193; 51%), lymphoepitheliomas (154; 41%), or unclassified carcinomas (31, 8%). Three fourths of the patients presented with AJCC Stage IV disease (T4, N0-3, 118 patients; T1-3, N2-3 164 patients). The treatment techniques included opposed lateral fields with or without an anteroposterior or an anterior oblique pairs for dose supplementation to the primary site. Average total doses per T-stage ranged between 60.2 and 72.0 Gy. Median follow-up time was 10 years (range 0.3 to 28.6 years). Results: A total of 103 patients (27%) developed distant metastases at a median time of 8 months (range: 1-90 months). Actuarial rates for distant metastasis were 30%, 32%, 32% at 5, 10, and 20 years, respectively. Actuarial rates for disease specific survival at the same time points were 53%, 45%, and 39% with 184 patients (49%) dying of their nasopharyngeal cancer. Advanced T-stage, N-stage, and non-lymphoepithelioma histology were independent adverse prognostic factors for disease specific survival. Advanced N-stage and low neck disease were independent adverse prognostic factors for distant metastasis with a very high rate of distant metastases for those patients who presented with both adverse factors (relative risk 7.86). On average, patients with distant metastasis lived 5 months after they were diagnosed with metastatic disease (range: 0-172 months), although four

  9. 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

  10. 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

  11. Prognostic factors in invasive bladder carcinoma treated by combined modality protocol (organ-sparing approach)

    International Nuclear Information System (INIS)

    Purpose: The results of bladder sparing approach for the treatment of muscle-invasive bladder cancer, using a combination of transurethral resection (TUR), chemotherapy, and radiotherapy, are encouraging. The survival of patients treated by this method is similar to the survival of patients treated by radical cystectomy. The aim of our study was to find out which pretreatment characteristics influence the survival of patients treated by organ sparing approach that would enable us to identify the patients most suitable for this type of treatment. Methods and Materials: The prognostic value of different factors, such as age, gender, performance status, hemoglobin level, clinical stage, histologic grade, presence of obstructive uropathy, and completeness of TUR, has been studied in 105 patients with invasive bladder cancer, who received a bladder sparing treatment in the period from 1988 to 1995. They were treated with a combination of TUR, followed by 2-4 cycles of methotrexate, cisplatinum, and vinblastine polychemotherapy. In complete responders the treatment was completed by radiotherapy (50 Gy to the bladder and 40 Gy to the regional lymph nodes), whereas nonresponders underwent cystectomy whenever feasible. Results: Our study has confirmed an independent prognostic value of performance status, histologic grade, and obstructive uropathy, for the disease-specific survival (DSS) of bladder cancer patients treated by a conservative approach. We believe that performance status best reflects the extent of disease and exerts significant influence on the extent and course of treatment, while obstructive uropathy is a good indicator of local spread of the disease, better than clinical T-stage. Our finding that histologic grade is one of the strongest prognostic factors shows that tumor biology also is a very important prognostic factor in patients treated by conservative approach. Conclusion: Patients with muscle-invasive bladder cancer who are most likely to benefit

  12. An analysis of the fate of patients treated radically for glottic carcinoma of the larynx

    International Nuclear Information System (INIS)

    Conventional survival curves remain the best means of describing events after treatment of a group of patients with cancer but they have limitations when the effects of different secondary events and their treatment are also being assessed. Twelve mutually exclusive categories of patients have been defined with respect to primary control, radiation necrosis, nodal, metastatic spread and death. In patients with glottic carcinoma of the larynx treated with radical radiotherapy, the resulting patterns of fate are presented for three stage grouping T1N0, T2N0 and Tsub(3-4)N0. Radiation necrosis is a much less serious complication (0% mortality) than primary failure (50% mortality). This supports a very radical radiotherapeutic policy for advanced carcinoma of the larynx. The development of nodal disease is of very different significance when the state of the primary disease is considered in association with it, nodal disease alone being the only salvageable complication. There are relatively small numbers of patients with advanced disease in whom primary failure alone is a problem (23% Tsub(3-4)) and even including patients with primary failure and nodal disease as potentially salvageable only identifies 37% of patients with advanced disease with any chance of responding to an improved modality of treatment.

  13. 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.

  15. Carcinoma of penis. Review of cases treated by surgery and radiation therapy 1960-1977

    International Nuclear Information System (INIS)

    Cases of squamous cell carcinoma of the penis treated by surgery and radiation therapy at Moffitt Hospital, University of California, and Mount Zion Hospital and Medical Center are reviewed. Only cases followed for more than three years or with autopsy findings are presented. For the primary lesion, over-all surgical control rate locally was 15/17 or 88 per cent. Over-all control rate with radiation therapy alone was 9/12 (75 per cent), and with surgical salvage 11/12 (92 per cent). Radiation therapy appears to be the treatment of choice for early stage lesions, reserving surgery for salvage. Prophylactic ilioinguinal lymph node dissection for N0 lesions is not warranted. The role of chemotherapy needs further investigation

Methodology: We conducted a retrospective analysis of 66 patients treated HC Basal cell carcinoma between the period from January 1, 2007 and June 30, 2011. Results: For stages T1 and T2 treated with surgery alone, was quantified one relative frequency (fr)of SVLE 0.81 (31/39). For RT -treated patients, there were no in the sample for T1 and T2 was quantified one fr. SVLE of 1 (3/3) at doses > 60 Gy. For those with positive margins who received postoperative adjuvant RT quantified one fr. SVLE of 1 (8 /8) For patients with T3 disease surgery was performed more average dose radiotherapy 54.2 Gy. obtaining a fr. SVLE 0.5 (2/ 4). In patients with T4 disease with surgery more RT (2) non-responders complete. The dose delivered was in the range of 50 to 60 Gy. The other two did not complete treatment. Conclusions: For the early stages results are comparable both in surgery RT as exclusive. For those operated with positive margins benefit from radiation treatment adjuvant with a minimum dose of 60 Gy. In the later stages there is a benefit in most radiotherapy combination of surgery, dose can be delivered mayores.REVISIÓ

  17. Prognosis of esophageal squamous cell carcinoma treated by endoscopic submucosal dissection

    International Nuclear Information System (INIS)

    One hundred and fifty eight patients who had esophageal squamous cell carcinoma (SCC) were treated by endoscopic submucosal dissection (ESD) from Jan. 2,000 to Dec. 2006. The invasion depth was divided as epithelium (EP), Lamina propria mucosa (LPM), muscularis mucosa (MM) and submuosal layer. When the depth of submucosal invasion was 200 micrometers or less, the invasion depth was defined as SM1. In this study, out of 158 patients 28 patients had MM SCC, and 12 patients had SM1 SCC. The additional therapies such as Esophagectomy or Chemo Radio Therapy (CRT) were recommended to the patients, when lymphatic permeation was found. Among the patients who had MM SCC, 5 patients had lymphatic permeation. Among the patients who had SM1 SCC, 4 patients had lymphatic permeation. 2 MM and 2 SM1 patients were treated by CRT and the other 5 patients who had lymphatic permeation refused the additional therapy because of other diseases. All 4 patients who were treated by CRT are alive, but lymph node metastasis was found in 2 of the patients who refused CRT. One died of esophageal SCC, and one died of another disease. No lymph node metastasis was found in 23 patients who had MM without lymphatic permeation, and 8 patients who had SM1 without lymphatic permeation. According to our data, the indication of esophageal ESD could be expanded for MM or SM1 SCC without lymphatic permeation. (author)

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

  20. Evaluation of parotid function using dynamic parotid scintigraphy in nasopharyngeal carcinoma patients treated with external beam radiation therapy

    International Nuclear Information System (INIS)

    Objective: To evaluation of the parotid function using dynamic parotid scintigraphy in nasopharyngeal carcinoma patients treated with external beam radiation therapy. Methods: Twenty-one nasopharyngeal carcinoma patients were included into this study. Dynamic parotid scintigraphy was performed before and after external beam radiation therapy. Semi-quantitative parameters of parotid (uptake index, excretion rate and excretion index) was used to evaluate the changes of parotid function. Results: UI, ER and EI of parotid were decreased markedly after external beam radiation therapy, t is 56.65, 41.34, 30.69 respectively, P<0.001. The uptake and excretion function of the parotid were all impaired, which correlated with the dray mouth symptom of the patients. Conclusion: Dynamic parotid scintigraphy can play a key role in the evaluation of parotid function in nasopharyngeal carcinoma patients treated with external beam radiation therapy. (authors)

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

    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)

    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.

    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.

  10. 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

Conclusion: Correct and proper perioperative nursing care is of significant importance for the prevention of complications and for the therapeutic effectiveness. (authors)

  12. Treatment results and prognostic factors in 101 men treated for squamous carcinoma of the penis

    International Nuclear Information System (INIS)

    Purpose: This retrospective study was performed to assess the treatment outcome and prognostic factors in 101 men with invasive squamous carcinoma of the penis treated at the Royal Marsden Hospital between 1960-1990. Methods and Materials: The tumor was confined to the glans penis (T1) in 79 patients, 82 were node negative (N0), and two patients had distant metastases at presentation. The histology was Grade 1 (G1) in 36, Grade 2 (G2) in 18, Grade 3 (G3) in 28, and unknown in 19 patients. Node-positive disease was commoner in patients with G3 (p = 0.02) or T2/3/4 tumors (p = 0.007). Treatment for the primary tumor was external beam radiotherapy (EBRT) in 59, interstitial brachytherapy in 13, and partial or total penectomy in 29 patients. The median dose, dose/fraction, and treatment time for EBRT was 60 Gy, 2 Gy/fraction, and 46 days, respectively. Eighty patients received no inguinal node treatment, 13 had EBRT (4 with chemotherapy), and 8 underwent groin dissection at presentation. Results: During a median follow-up of 5.2 years (2 months-22 years), 56 patients died (penile cancer 31, inter-current illness 23 and unknown cause 2), giving 10 year overall and cause-specific survival (CSS) of 39 and 57%, respectively. Adverse prognostic factors for CSS on univariate analysis were G3, ulcerative/fungating or T2/3/4 tumors, node positive, Jackson's Stage 2/3/4, and surgical treatment for the primary. All but the last two were significant independent prognostic factors for CSS on multivariate analysis. Penile or perineal recurrence or residual disease after initial treatment was seen in 36 out of 98 evaluable patients, giving a 10-year local failure rate (LFR) of 45%. Local failure after initial treatment was successfully salvaged in the majority (26 out of 36) of patients with further surgery or radiotherapy, and local control was achieved ultimately in 74 out of 77 T1, 7 out of 12 T2; 3 out of 3 T3, and 3 out of 5 T4 tumors. In the 44 evaluable patients with T1

  13. Treatment outcome of ductal carcinoma in situ patients treated with postoperative radiation therapy

    International Nuclear Information System (INIS)

    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.

    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.

    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.

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.

  16. Prognostic factors in invasive squamous cell carcinoma of the vulva treated with surgery and irradiation

    International Nuclear Information System (INIS)

    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.

    2013-01-01

    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.

    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.

    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.

  3. Treatment outcome and analysis of the prognostic factors of ductal carcinoma in situ treated with breast conserving surgery and radiotherapy

    International Nuclear Information System (INIS)

    To evaluate the survival rate, local failure rate and patterns of failure, and analyze the prognostic factors affecting local relapse of ductal carcinoma in situ treated with breast conserving surgery and radiotherapy. From June 1995 to December 2001, 96 patients with ductal carcinoma in situ treated with breast conserving surgery and radiotherapy were retrospectively analyzed. The operations were either local or wide excision in all patients, with an axillary lymph node dissection performed in some patients. Radiation dose to the whole breast was 50.4 Gy, over 5 weeks, with 1.8 Gy daily fractions, with additional doses (10 ∼ 14 Gy) administered to the primary tumor bed in some patients with close (≤ 2 mm) or positive resection margin. The median follow-up period was 43 months (range 12 ∼ 102 months). The 5-year local relapse free survival and overall survival rates were 91 and 100% respectively. Local relapse occurred in 6 patients (6.3%). Of the 6 recurrences, one was invasive ductal cell carcinoma. With the exception of one, all patients recurred 2 years after surgery. There was no regional recurrence or distant metastasis. Five patients with local recurrence were salvaged with total mastectomy, and are alive with no evidence of disease. One patient with recurrent invasive ductal cell carcinoma will receive salvage treatment. On analysis of the prognostic factors affecting local relapse, none of the factors among the age, status of resection margin, comedo type and nuclear grade affected local relapse. Operation extent also did not affect local control (ρ = 0.30). In the patients with close resection margin, boost irradiation to the primary tumor bed did not affect local control (ρ = 1.0). The survival rate and local control of the patients with ductal carcinoma in situ treated with breast conserving surgery and radiotherapy were excellent. Close resection margin and boost irradiation to the primary tumor bed did not affect local relapse, but further

  4. FADD Expression as a Prognosticator in Early-Stage Glottic Squamous Cell Carcinoma of the Larynx Treated Primarily With Radiotherapy

    International Nuclear Information System (INIS)

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

    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

  10. Retrospective analysis of 108 ductal carcinomas in situ of the breast treated by radiosurgery association

    International Nuclear Information System (INIS)

    Purpose. - To evaluate survival and prognostic factors of 108 patients with clinically or mammo-graphically detected ductal carcinoma in situ (DCIS), treated from 1980 to 1996 by complete local excision followed by external irradiation. Patients and methods. - The median age was 51 (range 37-80). All the patients underwent surgery consisting of a wide resection of the mammary gland harboring the tumour. The surgical specimens were sent to the pathologists to get information on histology and margin clearance; all the slides were reviewed by one of us to assess the tumoral diameter. External beam therapy was delivered within 8 weeks after surgery. The prescribed irradiation dose was 50 Gy in 25 fractions to be given in 5 weeks. The median duration of follow-up was 93 months (range 40-173). Results. - There were nine patients with local recurrence (8.3%); three patients had local recurrence of DCIS and six patients developed invasive breast cancer. The treatment of local recurrence consisted of mastectomy with or without axillary dissection (eight cases) and quadrant-ectomy (one case). The 5-year and 10-year ipsilateral recurrence-free rate was respectively 92 and 89%. The 10-year cause specific survival was 100%. In univariate analysis, size ≥ 10 mm, age < 45 years old and margin status were significant P = 0,02. P 0,03, P = 0,005; margin status was significant in multivariate analysis (P < 0,02). Conclusion. - These results are in keeping with those of the literature. They could be improved by the mass screening campaign, which is going on since January 1990 among women aged 50 - 74 years.

    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.

    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

  15. 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

  16. T but not N stage predicts survival for patients with tonsillar carcinoma treated with external radiotherapy and brachytherapy

    International Nuclear Information System (INIS)

    Background. Our aim was to determine the efficacy of a therapeutic schedule including external radiation and brachytherapy in a consecutive and retrospective series of tonsillar carcinoma patients. Patients and methods. Ninety-six patients with tonsillar carcinoma were treated between 1988 and 2000 and were followed up for at least for three years. All patients were treated with accelerated hyperfractionated external radiotherapy, 68 patients had additional brachytherapy and 69 patients with advanced stages also received chemotherapy. There was no planned surgery even though 73% had N+ disease. Eleven patients with persistent neck nodes underwent ultimate salvage surgery. Results. The overall three-year survival (OS) was 70%. OS for the T stage was T1 90%, T2 89%, T3 54% and T4 60%. The corresponding numbers for the N stage were N0 61.5%, N1 73%, N2 78% and N3 66%. Accordingly OS was influenced by the T stage (p>0.001) rather than by N stage. Only four patients with salvage surgery had viable tumour cells in the specimen, their survival was not inferior. Discussion. The primary tumour stage is an essential determinant for survival in patients with irradiated tonsillar carcinoma. Neck dissection should be confined only as a salvage procedure

  17. The clinical application of C arm CT imaging in diagnosing and treating hypo-vascular primary hepatic carcinomas

    International Nuclear Information System (INIS)

    Objective: To investigate the clinical application of C arm CT imaging technique in diagnosing and treating of hypo-vascular primary hepatic carcinomas. Methods: Forty-three patients with hypo-vascular primary hepatic carcinomas were enrolled in this study. All the patients underwent DSA and C arm CT imaging (Philips dual x-ray flat-panel digital imaging system) before transcatheter arterial chemoembolization (TACE). The imaging findings were retrospectively analyzed. The detection rate of hepatic tumors estimated before TACE were compared among CT/MRI, DSA and C arm CT imaging. Results: After TACE a total of 97 hypo-vascular tumors were found on CT scanning. The detection rates of hepatic tumors on CT/MRI, DSA and C arm CT imaging were 71.1% (69/97), 78.4% (76/97) and 89.7% (87/97), respectively, with P0.05. Conclusion: C arm CT imaging technique is superior to CT/MRI and DSA in detecting the hypo-vascular hepatic tumors. This technique can more precisely and more sensitively demonstrate the hepatic lesions, especially for the tumors with a diameter smaller than 10 mm. Therefore, this technique has great clinical value in treating hepatocellular carcinomas. (authors)

    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.

  20. 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)

  2. 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)

  3. Clinical analysis of ear carcinoma treated in the Department of Otolaryngology, Niigata University Hospital. Focus on correlation between treatment method and prognosis

    International Nuclear Information System (INIS)

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

    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)

  8. Supracystic urine diversion in patients with bladder carcinoma treated by cystectomy preceded by short type (2000 R) radiotherapy

    International Nuclear Information System (INIS)

    The authors assessed the results of supracystic urine diversion in 50 patients treated by cystectomy for bladder carcinoma who had short type radiotherapy (2000 R) before the operation. It was found that preoperative radiotherapy caused no difficulties during subsequent cystectomy and the observed postoperative complications should be related rather to the surgical technique. It seems that indications to urine diversion by the method of Goodwin or Coffey should be considered with greater caution. In patients past the age of 65 years and those with more advanced neoplasm (T-3, T-4) bilateral ureterocutaneoustomy should be performed more frequently for superacystic urine diversion. (author)

  11. 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

  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

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. Conclusions 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

  14. 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.

    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.

  19. Relation between simple cytological test and persistence of disease in radiation-treated uterine cervix carcinomas

    International Nuclear Information System (INIS)

    A cytological study was conducted covering 174 epidermoid uterine cervix carcinoma patients who had been given combined radiation therapy. The changes were assessed in the karyopyknotic index (KPI) as related to radiation therapy and the incidence of local relapses. At the limit KPI value of 10, the average reliability of the method for diagnosing persistence in the group under study was 83.0%. Patients showing KPI of more than 10 at six weeks following the termination of radical radiation therapy represent a poor prognosis group whereas those showing KPI values lower than 10 have good prognosis. The results show that no strict hormonal dependence of the KPI value exists in uterine ceervix carcinoma patients; only a different situation exists which is probably due to the tumor-organism interaction or to the metabolism of the tumor itself.

  20. 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)

    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.

    Chemotherapy for lung cancer not only has severe side effects but frequently also exhibits limited, if any clinical effectiveness. Dexamethasone (DEX) and similar glucocorticoids (GCs) such as prednisone are often used in the clinical setting, for example, as cotreatment to prevent nausea and other symptoms. Clinical trials evaluating the impact of GCs on tumour control and patient survival of lung carcinoma have never been performed. Therefore, we isolated cancer cells from resected lung tum...

  9. 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

    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 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.

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.

  15. Assessment of thyroid function in patients with laryngeal carcinoma treated surgically and with radiotherapy

    International Nuclear Information System (INIS)

    In 40 patients with laryngeal carcinoma after total laryngectomy and radiotherapy the triiodotyronine binding index, total thyroxine level, serum free thyroxine index were determined before, during and after treatment. At the same time thyroid iodine uptake was determined by the routine method. Surgical treatment as well as radiotherapy caused lowering of thyroid functions. These changes had a high tendency for return to normal values, not earlier, however, than 6 months after treatment. The authors stress that endocrine thyroid disturbances may have an important influence on delay of psychic rehabilitation and speech training in laryngectomized patients. (author)

  16. Carcinoma of the larynx treated with hypofractionated radiation and hyperbaric oxygen: long-term tumor control and complications

    International Nuclear Information System (INIS)

    Purpose: To evaluate the long-term outcome with respect to local control, survival, and complications in a cohort of patients with locally advanced laryngeal carcinoma treated with hypofractionated radiation and hyperbaric oxygen at 4 atmospheres of pressure (HBO-4). Methods and Materials: Between January 1970 and August 1982, 45 patients with locally advanced carcinoma of the larynx were treated with primary radiation using a unique hypofractionated schedule of 2 fractions of 11 Gy separated by 21 days, with concomitant HBO-4 during each radiotherapy session. To avoid seizures, discomfort and other complications of HBO-4, each session was performed under general anesthesia. All patients had pathologically confirmed squamous cell carcinoma of the glottic (23) or supraglottic larynx (22) and were staged as follows: T2-5, T3-24, T-4-16; N0-26, N1-4, N2-13, N3-1. Patients were treated with opposed lateral wedged fields of 4-6MV photons, with a median field size of 5.5 x 9.75 to a total median dose of 22.5 Gy. Results: As of February 1998, follow-up was complete on all but one patient, who relocated to another country after 8 years. Complete clinical responses were observed in 39 (87%) of the cases. The 10-year local control rate for all 45 patients was 58%, and local control for the complete responders was 69%. Three patients underwent laryngectomy for complications and were found to have no pathological evidence of disease in the laryngectomy specimen. The 10-year survival of the overall population was 27%. The 10-year voice preservation rate for the the 39 complete responders was 55%. Acute mucosal and skin reactions were modest and acceptable. Significant late complications occurred in 14 patients consisting of severe fibrosis, necrosis, pharyngeal fistula, with 3 patients requiring laryngectomy for complications. The actuarial rate of severe complications at 5 years was 42%. Conclusions: The response rate and long-term tumor control rate obtained with this

  17. Prognostic value of p53 mutations in patients with locally advanced esophageal carcinoma treated with definitive chemoradiotherapy

    International Nuclear Information System (INIS)

    A significant correlation has been found between p53 mutation and response to chemotherapy or radiotherapy. To determine the prognostic value of p53 mutation in patients with locally advanced esophageal carcinoma treated with definitive chemoradiotherapy, p53 mutation was analyzed using the biopsied specimens taken for diagnosis. Concurrent chemoradiotherapy was performed for 40 patients with severe dysphagia caused by esophageal squamous cell carcinoma associated with T3 or T4 disease. Chemotherapy consisted of protracted infusion of 5-fluorouracil, combined with an infusion of cisplatinum. Radiation treatment of the mediastinum was administered concomitantly with chemotherapy. The p53 gene mutation was detected by fluorescence-based polymerase chain reaction single-strand conformation polymorphism (PCR-SSCP) methods. DNA sequences were determined for DNA fragments with shifted peaks by SSCP methods. Of the 40 patients, 15 had T3 disease and 25 had T4 disease; 11 patients had M1 lymph node (LYM) disease. Of the 40 patients, 13 (33%) achieved a complete response. The median survival time was 14 months, and the 2-year survival rate was 20%. Among the 40 tumor samples, p53 mutation was detected in 24 tumors (60%). The survival rate in the 24 patients with p53 mutation did not differ significantly from that in the 16 patients without p53 mutation. In contrast, the 15 patients with T3 disease survived longer than the 25 patients with T4 disease (P=0.016); however, the survival rate in the 11 patients with M1 LYM disease did not differ significantly from that in the 29 patients without M1 LYM disease. Concurrent chemoradiotherapy is potentially curative for locally advanced esophageal carcinoma, but p53 genetic abnormality has no impact on prognosis. (author)

  18. Peripheral T-lymphocytes and delayed hypersensitivity in surgically and radiologically treated patients with early stages of larynx-carcinoma

    International Nuclear Information System (INIS)

    122 patients with squamous-cell-carcinoma of the larynx (T1-stage) were examined after surgical or radiological treatment. None of these patients showed evidence of tumor recurrence. Peripheral T-lymphocytes and delayed hypersensitivity were studied in all these patients. According to their treatment, the patients were allotted into three groups and compared with a control group, consisting of 20 patients with nonneoplastic head- and neck-disease. The main finding was a significant decrease in the peripheral T-lymphocytes in surgically- or radiologically-treated patients with a squamous-cell-carcinoma of the larynx (T1-stage). This reduction of T-cells must be interpreted as a congenital or acquired defect of the immunocompetent system. In about half of the control cases the DNCB-tests showed no evidence of delayed hypersensitivity. In view of these results and those reported in the literature, the test should be used critically. In contrast to our earlier findings, where patients received radiotherapy over large areas including big vessels, radiation over a smaller, localised area does not lead to a significant depression of peripheral T-lymphocytes.

    International Nuclear Information System (INIS)

    A group of 381 patients with squamous cell carcinoma of the oral cavity and naso- and oropharynx treated with definitive radiotherapy were analyzed with respect to the incidence and precipitating factors of mandibular osteonecrosis. Elective dental extraction prior to therapy increased the incidence, and dental conservation decreased it. Spontaneous osteonecrosis did not occur with doses less than 6,000 rads in 6 weeks, and was uncommon (1.8 percent) at doses under 7,000 rads in 7 weeks. At doses over 7,000 rads, osteonecrosis developed in 9 percent. The incidence was greater in patients with tumors near bone (9.4 percent) than in those with tumors not next to bone (2.1 percent)

  20. 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

  1. 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

  2. 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

  3. 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.)

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

  7. 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)

  10. Locally-regionally advanced tonsillar squamous cell carcinoma treated with concurrent chemoradiotherapy

    International Nuclear Information System (INIS)

    Purpose: To perform a retrospective review of stage III-IV squamous cell carcinoma of the tonsil managed by definitive concurrent chemoradiotherapy (CCRT) in order to analyze the patients’ outcome and to evaluate the acute and late toxic effects of this treatment modality. Material and methods: Between January 2005 and December 2010, 36 patients with locally and/or regionally advanced tonsillar cancer underwent three dimensional conformal radiotherapy (3DCRT) with concurrent platinum-based chemotherapy. The dose prescription of the planning target volume for gross tumor and low-risk subclinical disease was 70 Gy and 50 Gy, respectively. Conventional fractionation with a daily dose of 2.0 Gy, 5 times per week was used. Concurrent chemotherapy consisted of cisplatin 30 mg/m2 given on a weekly basis. Acute and late radiotherapy-related toxicities were recorded using European Organization for Research and Treatment of Cancer/Radiation Therapy Oncology Group (EORTC/RTOG) grading system. The 3-year locoregional relapse-free survival (LRRFS), disease-free survival (DFS), and overall survival (OS) rates were calculated using the Kaplan-Meier method. Results: The median follow-up of all patients was 20.5 months (range, 5 to 90 months). The median followup of living patients was 59 months (range, 30 to 90 months). Complete response rates of the primary tumor and of the nodal disease were 72.2% and 64.0%, respectively. A complete composite response was present in 25 patients (69.4%). Treatment failure occurred in 15 out of 25 patients who achieved complete composite response following CCRT. The 3-year LRRFS, DFS, and OS rate was 38.8%, 27.8%, and 27.3%, respectively. Grade 3 mucositis occurred in 58.3% of patients. Xerostomia grade 2 was revealed in 72.2% of patients. Conclusion: Taking into account the low 3-year survival rates observed in our study and the high percentage of grade 2 xerostomia, it can be concluded that in the future, instead of 3DCRT with concurrent

    International Nuclear Information System (INIS)

    Objective: To summarize the efficacy and toxicities of induction chemotherapy followed by radiotherapy and adjuvant chemotherapy in the treatment of locally advanced nasopharyngeal carcinoma (NPC). Methods: From Oct. 1997 to Nov. 2000, 77 patients with histologically proven locally advanced NPC, staged according to the Fuzhou stage classification, were retrospectively studied. Before radical radio- therapy, the patients received 1-3 cycles cisplatin(PDD) 20 mg/m2 on Days 1-3 and fluorouracil(5-Fu) 500 nag/ma on Days 1-3 repeated every two weeks. Sixty-two patients also received calcium folinate (CF) 100 mg/m2 on Days 1-3. Two to four cycles of adjuvant chemotherapy was given 21 days after the completion of radiotherapy. All patients received radical radiotherapy by 60 Co to the nasopharynx and neck with a total dose of 64-78 Gy at 1.8-2.0 Gy per fraction over 7.0-7. 5 weeks to the primary site. The dose to the lymph nodes was 60-68 Gy. After-loading radiotherapy was given to the residual disease in 1 patient (20 Gy in 2 fractions). Results: The median follow-up was 60 months (ranged from 3 to 103 months). The 5-year overall urvival rate (OS), disease-free survival rate (DFS), relapse-free survival rate (RFS) and distant metastasis-free survival rate (DMSF) were 68%, 58%, 81% and 75%. The patients who received more than 3 cycles of chemotherapy or not had no significant effects on the OS (χ2=0.05, P=0.831). The incidence of grade 3 or 4 acute side-effects of radiotherapy was vomiting 1%, leukopenia 3%, mucositis 23% and skin reaction 5%, all of which eventually resolved. The most frequent late toxicities were hearing impairment (51% ). Patients with more than 3 cycles chemotherapy were more likely to have late hearing loss (z=2.06, P=0.039). Only one patient had radiation-induced brain damage. Conclusions: Induction chemo- therapy, radiotherapy and adjuvant chemotherapy for locally advanced nasopharyngeal carcinoma would result in a comparable outcome, but may

    2015-11-01

    Full Text Available Hepatocellular carcinoma (HCC is the third leading cause of cancer-related mortality worldwide. Epirubicin (EPI once acted as a main agent for HCC chemotherapy. However, the dosage-dependent side effects seriously limit its application in clinic. The purpose of this study is to develop an effective nanocarrier to improve the efficacy and overcome the limitations of EPI. In this regard, the EPI-complexed micelle (i.e., mPEG-b-PGA/EPI was prepared via the electrostatic interaction between the amino group in EPI and the carboxyl group in PGA segment of methoxy poly(ethylene glycol-block-poly(l-glutamic acid (mPEG-b-PGA, and the subsequent hydrophobic interaction among PGA/EPI complexes. The micelle appeared spherical with a diameter at around 90 nm and possessed a pH-sensitive release property of payload. The cytotoxicity and hemolysis assays in vitro, and the maximum tolerated dose tests in vivo confirmed that mPEG-b-PGA was a kind of safe material with excellent biocompatibility, while the drug-loaded micelle could obviously improve the tolerance of EPI. In addition, mPEG-b-PGA/EPI possessed significantly enhanced antitumor efficacy and security toward the H22-xenografted HCC murine model at macroscopic and microscopic levels compared with free EPI. All these results strongly indicate that mPEG-b-PGA/EPI may be a promising nanoplatform for EPI delivery in the chemotherapy of HCC.

  13. Sensori-neural hearing loss in patients treated with irradiation for nasopharyngeal carcinoma

    International Nuclear Information System (INIS)

    The present investigation has been carried out to evaluate the sensitivity of the inner ear to irradiation. Cochlear function was tested in a cohort of 22 patients before and 7-84 months after receiving external irradiation for nasopharyngeal carcinoma. The pre-irradiation sensori-neural hearing threshold at 500, 1000, 2000, and 4000 Hz was used as a baseline for the individual patient, and the observed sensori-neural hearing loss (SNHL) was calculated as the difference between pre- and post-irradiation values. The pre-irradiation hearing level or patient age was not correlated with the actual SNHL. In contrast, there was a significant correlation between the total radiation dose to the inner ear and the observed hearing impairment. SNHL was most pronounced in the high frequencies, with values up to 35 dB (4000 Hz) and 25 dB (2000 Hz) in some patients. The latent period for the complication appeared to be 12 months or more. The deleterious effect of irradiation on the hearing should be kept in mind both in treatment planning and in the follow-up after radiotherapy

    Taiga Otsuka

    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.

  15. Prognostic value of parapharyngeal extension in nasopharyngeal carcinoma treated with intensity modulated radiotherapy

    International Nuclear Information System (INIS)

    Background and purpose: The development of improved diagnostic and therapeutic techniques has revolutionized the management of nasopharyngeal carcinoma (NPC). The purpose of this study is to revaluate the prognostic value of parapharyngeal extension in NPC in the IMRT era. Material and methods: We retrospectively reviewed data from 749 biopsy-proven non-metastatic NPC patients. All patients were examined with magnetic resonance imaging (MRI) and received intensity-modulated radiotherapy (IMRT) as the primary treatment. Results: The incidence of parapharyngeal extension was 72.1%. A significant difference was observed in the disease-free survival (DFS; 70.3% vs. 89.1%, P < 0.001), distant metastasis-free survival (DMFS; 79.3% vs. 92.0%, P < 0.001), and local relapse-free survival (LRFS; 92.8% vs. 99.0%, P = 0.002) of patients with and without parapharyngeal extension. Parapharyngeal extension was an independent prognostic factor for DFS and DMFS in multivariate analysis (P = 0.001 and P = 0.015, respectively), but not LRFS. The difference between DMFS in patients with or without parapharyngeal space extension was statistically significant in patients with cervical lymph node metastasis (P < 0.001). Conclusions: In the IMRT era, parapharyngeal extension remains a poor prognosticator for DMFS in NPC, especially in patients with positive lymph node metastasis. Additional therapeutic improvements are required to achieve a favorable distant control in NPC with parapharyngeal extension

  16. Biological dosimetry in patients with differenced thyroid carcinoma treated with Iodine-131

    International Nuclear Information System (INIS)

    The differentiated thyroid carcinoma (DTC), constitutes the 90 % of the thyroid gland cancers. 80% of patients are cured after the initial therapy and 12% remained disease-free after successive treatments. The 24 patients included in this study represent a sample of the aforementioned 12% and 8%, with recurrence in the first decade post-treatment (local disease and/or recurrence at distance). The internal radiotherapy with 131I in patients with DTC is used within the therapeutic schema as a step post-thyroidectomy. The success of the therapy is to get a lethal dose in the tumor tissue, which depends on the therapeutic activity and the retention of 131I, without exceeding the dose of tolerance in healthy tissues. The most widespread way of administration is the empirical prescription which considers the clinical and laboratory parameters for its determination. In this work, the treatment protocol applied incorporates assessment by biological (DB) and internal (DI) dosimetry for estimating absorbed dose to the whole body and bone marrow to manage a personalized therapeutic dose for each patient. The biological dose estimation is based on the quantification of chromosomal aberrations, which is often referred to a dose-response curve in which lymphocytes are irradiated in vitro with 131I, allowing to determine the dose in vivo of circulating lymphocytes patients

  17. Development of coronary artery stenosis in a patient with metastatic renal cell carcinoma treated with sorafenib

    International Nuclear Information System (INIS)

    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. 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. 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

    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.

  20. Epidermal Growth Factor Receptor Expression As Prognostic Marker in Patients With Anal Carcinoma Treated With Concurrent Chemoradiation Therapy

    International Nuclear Information System (INIS)

    Purpose: To investigate the prognostic value of epidermal growth factor receptor (EGFR) expression in pretreatment tumor biopsy specimens of patients with anal cancer treated with concurrent 5-fluorouracil and mitomycin C-based chemoradiation therapy (CRT). Methods and Materials: Immunohistochemical staining for EGFR was performed in pretreatment biopsy specimens of 103 patients with anal carcinoma. EGFR expression was correlated with clinical and histopathologic characteristics and with clinical endpoints, including local failure-free survival (LFFS), colostomy-free survival (CFS), distant metastases-free survival (DMFS), cancer-specific survival (CSS), and overall survival (OS). Results: EGFR staining intensity was absent in 3%, weak in 23%, intermediate in 36% and intense in 38% of the patients. In univariate analysis, the level of EGFR staining was significantly correlated with CSS (absent/weak vs intermediate/intense expression: 5-year CSS, 70% vs 86%, P=.03). As a trend, this was also observed for DMFS (70% vs 86%, P=.06) and LFFS (70% vs 87%, P=.16). In multivariate analysis, N stage, tumor differentiation, and patients’ sex were independent prognostic factors for CSS, whereas EGFR expression only reached borderline significance (hazard ratio 2.75; P=.08). Conclusion: Our results suggest that elevated levels of pretreatment EGFR expression could be correlated with favorable clinical outcome in anal cancer patients treated with CRT. Further studies are warranted to elucidate how EGFR is involved in the response to CRT

    Background and study aims: Endoscopic papillectomy is currently used to treat noninvasive tumors of the papilla of Vater, but it is seldom reported for treatment of similar tumors of the minor papilla. This report describes the case of a 69-year-old female with a tumor located at the duodenal minor papilla. Findings of duodenoscopy, biopsy, and pancreatography indicated that her noninvasive tumor of the minor papilla was suitable for treatment with endoscopic resection. Glycerol-injected endoscopic mucosal resection (EMR) was performed, and the resected material histologically showed carcinoma in the adenoma, negative for neoplastic extension at the cut margin. No complications occurred during the treatment course, and no recurrence has been recognized for 80 months. Unlike the major papilla of Vater, the minor papilla can be lifted up by submucosal injection. Noninvasive epithelial tumors of the duodenal minor papilla without extension to the pancreatic duct can be successfully treated with EMR, as the technique is easy, it is minimally invasive, and it is curative.

    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

    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.

    Full Text Available Abstract Background Because intraductal papillary mucinous neoplasm of the bile duct (IPMN-B is believed to show a better clinical course than non-papillary biliary neoplasms, it is important to make a precise diagnosis and to perform complete surgical resection. Case presentation We herein report a case of malignant IPMN-B treated by right trisectionectomy with caudate lobectomy and extrahepatic bile duct resection. Radiologic images showed marked dilatation of the left medial sectional bile duct (B4 resulting in a bulky cystic mass with multiple internal papillary projections. Duodenal endoscopic examination demonstrated very patulous ampullary orifice with mucin expulsion and endoscopic retrograde cholangiogram confirmed marked cystic dilatation of B4 with luminal filling defects. These findings suggested IPMN-B with malignancy potential. The functional volume of the left lateral section was estimated to be 45%. A planned extensive surgery was successfully performed. The remnant bile ducts were also dilated but had no macroscopic intraluminal tumorous lesion. The histopathological examination yielded the diagnosis of mucin-producing oncocytic intraductal papillary carcinoma of the bile duct with poorly differentiated carcinomas showing neuroendocrine differentiation. The tumor was 14.0 × 13.0 cm-sized and revealed no stromal invasiveness. Resection margins of the proximal bile duct and hepatic parenchyma were free of tumor cell. The patient showed no postoperative complication and was discharged on 10th postoperative date. He has been regularly followed at outpatient department with no evidence of recurrence. Conclusion Considering a favorable prognosis of IPMN-B compared to non-papillary biliary neoplasms, this tumor can be a good indication for aggressive surgical resection regardless of its tumor size.

  5. Late Rectal Complication in Patients Treated with High Dose Rate Brachytherapy for Stage IIB Carcinoma of the Cervix

    International Nuclear Information System (INIS)

    Purpose : This paper reports a dosimetric study of 88 patients treated with a combination of external radiotherapy and high dose rate ICR for FIGO stage IIB carcinoma of the cervix. The purpose is to investigate the correlation between the radiation doses to the rectum. external radiation dose to the whole pelvis. ICR reference volume. TDF, BED and the incidence of late rectal complications, retrospectively. Methods and Materials : From November 1989 through December 1992, 88 patients with stage IIB cervical carcinoma received radical radiotherapy at Department or Radiation Oncology in Yonsei University Hospital. Radiotherapy consisted of 44-54 Gy(median 49 Gy) external beam irradiation plus high dose rate intracavitary brachy therapy with 5 Gy per fraction twice a week to a total dose of 30 Gy on point A. The maximum dose to the rectum by contrast(r,R) and reference rectal dose by ICRU 38(dr, DR) were calculated. The ICR reference volume was calculated by Gamma Dot 3.11 HDR planning system, retrospectively. The time-dose factor(TDF) and the biologically effective dose (BED) were calculated. Results : Twenty seven(30.7%) of the 88 patients developed late rectal complications : 12 patients(13.6%) for grade 1, 12 patients(13.6%) for grade 2 and 3 patients(3.4%) for grade 3. We found a significant correlation between the external whole pelvis irradiation dose and grade 2, 3 rectal complication. The mean dose to the whole pelvis for the group of patients with grade 2, 3 complication was higher, 4093.3±453.1 cGy, than that for the patients without complication 3873.8±415.6 (0.05< p<0.1). This investigation has revealed a significant correlation between the dose calculated at the rectal dose by ICRU 38(DR) or the most anterior rectal dose by contrast(R), dose to the whole pelvis and the incidence of grade 2, 3 late rectal complications in patients with stage IIB cervical cancer undergoing external beam radiotherapy and HDR ICR. Thus these rectal reference points doses

    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.

  7. Treating hepatic carcinoma with internal mammary artery blood supply through transcatheter arterial chemoembolization

    International Nuclear Information System (INIS)

    Objective: To study blood supply by the internal mammary artery (IMA)for hepatic carcinoma and evaluate the efficacy and safety of transcatheter arterial chemoembolization (TACE)via IMA. Methods: 86 cases of hepatic cancer(HCC) fed by the IMA underwent TACE of the IMA. All of the patients had previously undergone several TACE for HCC. 16 patients had undertaken percutaneous microwave coagulation therapy in addition to TAE. 4 patients had a history of surgery for upper abdomen. Plain and enhanced CT and MRI scannings were performed before operation. Internal mammary arteriography was carried out during the interventional procedure to clarify the feeding range and then the superselected catheterization of the feeding branch was done with TACE. The IMA angiographic features, tumor location, clinical observation, laboratory tests, imageology were evaluated, and finally were correlated with the angiographic findings of the IMA. Results: All lesions were massive type and located at the ventral aspect and subcapsular region of the liver: 57 cases in segment 4, 5, 8, and 29 cases in segment 5, 7, 8. Recurrent HCCs were supplied by the right IMA in 80 cases, from the left IMA in 5 cases and with the bilateral IMA in 1 case. Lipiodol-TACE of the IMA for HCC can be performed without skin complications in cases of subselective catheterization. Conclusion Tumors located ventrally and superficially in the liver may recruit blood supply through IMA collaterals, often occurring in massive type of HCC after several times of TACE. TACE of IMA is safe and has become technically feasible in almost all patients, although cutaneous damage should be cautious during the interventional procedure. (authors)

    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.

  9. Outcomes of Low-Risk Ductal Carcinoma In Situ in Southeast Asian Women Treated With Breast Conservation Therapy

    International Nuclear Information System (INIS)

    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

    2014-11-01

    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.

  12. Prognostic value of retropharyngeal lymph nodes in nasopharyngeal carcinoma treated by intensity modulated radiotherapy (IMRT)

    International Nuclear Information System (INIS)

    Objective: To investigate the correlation of the the positive rate and necrosis rate of retropharyngeal lymph nodes with the clinical effects of intensity modulated radiotherapy (IMRT) in treatment of nasopharyngeal carcinoma (PNC). Methods: Seventy-two patients with PNC, 50 males and 22 females,with the median age of 50, underwent IMRT delivered into 33 times. The retropharyngeal lymph nodes involved and positive lymph nodes of neck were delineated on the CT image. The median dose and median fractionated dose for gross tumor volume (GTV) were 70.0 and 2.12 Gy respectively, and the median dose and median fractionated dose for clinical target volume (CTV) were 70.0 and 2.12 Gy respectively. The patients were followed up for 36 (5-54) months. Results: The metastasis rate of the neck lymph nodes was 90.3%, the metastasis rates in the regions Ⅰ-Ⅴ were 2.8%, 86.0%, 51.4%, 20.8%, and 37.5%, respectively. The metastasis rate of the retropharyngeal lymph nodes was 79.2%, and specifically the metastasis rates of the left, right, and bilateral retropharyngeal lymph nodes were 51.4%, 45.9%, and 18.1%, respectively. The cross metastasis rate was 6.9%. Necrosis of the retropharyngeal lymph nodes was found in 15 cases. The necrosis rates of the left, right, and bilateral retropharyngeal lymph nodes were 21.6%, 27.2%, 15.4%, respectively. Retropharyngeal lymph nodes metastasis was significantly correlated with N stage and clinical stage (Fuzhou 92:r =-0.383, -0.314, P<0.05; UICC:r =-0.434, -0.306, P<0.05). Local recurrence was observed in 4 patients,6 patients had distant metastasis, and 7 patients died. The positiveness of retropharyngeal lymph nodes was significantly correlated with the recurrence rate, distant metastasis rate,survival rate,and disease free survival rate (r = 0.085, 0.138, -0.140, -0.124, P<0.05), and the necrosis of the retropharyngeal lymph nodes was significantly correlated with the recurrence rate and distant metastasis rate (r = 0.256, -0.057, P<0

  13. Is there a sexual function decline in nasopharyngeal carcinoma survivors treated with radiotherapy?

    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. 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

  15. 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.

However none of the patients had pulmonary progressive disease, showed by radiographic examinations. Owners revealed treatment satisfaction in regards to quality of life improvement, easy M8 administration, good M8

  17. 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

  18. Analysis of complications of cervix carcinoma treated by radiotherapy using the Franco-Italian glossary

    International Nuclear Information System (INIS)

    We analysed the complications of 215 patients with uterine cervix cancer, treated by radiotherapy (RT) alone. It was done according to the rules of the Franco-Italian glossary, presented at the 7th ESTRO meeting, held in The Hague on September 1988. They were ranked by organ sites and by degrees of gravity. The analysis was done on the total number of complications and they were scored at the highest reached grade of gravity. Seventy one complications were found in 55 patients; they were studied by patient, degree of severity, time of onset, organ system and grade, time of onset and grade, time of onset and organ sites, stage and RT doses and brachytherapy volumes. The importance of the study of complications is stressed, particularly when treatment combines external RT and brachytherapy; some guidelines are given to avoid severe complications.

    1990-12-01

    This paper deals with 70 cases of primary liver cancer treated by externally applying Pu Tuo plaster and internally taking oral Chinese herbal medicine. In term of the statistic, of all the cases applied the plaster, 96.7% has proved to be effective in alleviating the pain, 83.5% was remarkable. It has significantly improved the quality of the patients' later lifes. Applying Pu Tuo plaster with taking oral Chinese herbal medicine, the patients could survive longer. On average, after the treatment, the patient could live ten and half months, 44.8% of the II-stage liver cancer patients applied the plaster could live as long as one year, the longest one has been living more than 2 years and 8 months, he looks still well now. He has been working since 1987. In recent B-ultrasonic examination, the patient's primary focus disappeared, and alpha-fetoprotein test turned to be negative. PMID:2292117

  20. Biological dosimetry of patients with differenced carcinoma of thyroid treated with Iodine-131

    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

    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.

    Full Text Available Everolimus is a mammalian target of rapamycin (mTOR inhibitor approved for the treatment of metastatic renal cell carcinoma (mRCC. We aimed to assess the association between the baseline values and treatmentrelated modifications of total serum cholesterol (C, triglycerides (T, body mass index (BMI, fasting blood glucose level (FBG and blood pressure (BP levels and the outcome of patients treated with everolimus for mRCC.177 patients were included in this retrospective analysis. Time to progression (TTP, clinical benefit (CB and overall survival (OS were evaluated.Basal BMI was significantly higher in patients who experienced a CB (p=0,0145. C,T and C+T raises were significantly associated with baseline BMI (p=0.0412, 0.0283 and 0.0001. Median TTP was significantly longer in patients with T raise compared to patients without T (10 vs 6, p=0.030, C (8 vs 5, p=0.042 and C+T raise (10.9 vs 5.0, p=0.003. At the multivariate analysis, only C+T increase was associated with improved TTP (p=0.005. T raise (21.0 vs 14.0, p=0.002 and C+T increase (21.0 vs 14.0, p=0.006 were correlated with improved OS but were not significant at multivariate analysis.C+T raise is an early predictor for everolimus efficacy for patients with mRCC.

  3. A case of metastatic carcinoma of the iris successfully treated by argon laser photocoagulation and 60Co therapy

    International Nuclear Information System (INIS)

    A 69-year-old female developed visual impairment and congestion in the right eye. She had been treated for small cell carcinoma in the left lung for the past 8 months with cytostatics and radiation. Three whitish gray nodules were located on the iris at 10-11 o'clock in the right eye. Three smaller nodules were present in the chamber angle in the same sector. The corrected visual activity of the affected eye was 0.3. The left eye was intact. We performed total iridectomy and sclerotomy to remove the tumors. The resected tissue showed the same cell type as in the lung. Two days after surgery, multiple nodules appeared on the entire iris surface and the chamber angle apparently due to dissemination of tumor cells by the surgical procedure. Repeated argon laser photocoagulation aimed on the cancer nodules was very effective in supressing the tumor and maintaining the visual acuity without severe side effects for the next 5 months, until intravitreal metastasis and death ensued. 60Co therapy was noticeably effective to extinguish the tumor mass in the anterior chamber and in the vitreous cavity. We recommend argon laser photocoagulation for metastatic iris tumor in the initial stage and 60Co therapy in the terminal stage. (author)

  4. Predictive Factors of Downstaging of Hepatocellular Carcinoma Beyond the Milan Criteria Treated with Intra-arterial Therapies

    International Nuclear Information System (INIS)

    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.

  6. Change of plasma transforming growth factor-β1 levels in nasopharyngeal carcinoma patients treated with concurrent chemo-radiotherapy

    International Nuclear Information System (INIS)

    Our aim was to study the correlation between plasma transforming growth factor (TGF) -βl level and radiation-induced mucositis and dermatitis in nasopharyngeal carcinoma (NPC) patients. Blood samples obtained from patients treated with concurrent chemo-radiotherapy (CCRT) were divided into two groups according to the pre-treatment plasma TGF-β1 level (≥7.5 ng/ml as group 1 and <7.5 ng/ml as group 2). Enzyme-linked immunosorbent assay (ELISA) was used for the measurement of the TGF-β1 level. Radiation toxicity was evaluated according to Radiation Treatment Oncology Group criteria. Data were analyzed by the generalized estimation equation method. TGF-β1 levels of group 1 patients were decreased significantly (P=0.002) at the end of the treatment. The rate of decrease was 0.12 ng/ml per fraction (P=0.02). The average TGF-β1 level in patients who suffered acute radiation morbidity (grade ≥2) was significantly higher (P=0.0057) than that of those who suffered less (grade <2). A lower pre-treatment plasma TGF-β1 level and the grade of radiation toxicity both appeared to contribute to the elevated plasma TGF-β1 after CCRT. (author)

  7. 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)

  8. Carcinomas of the Paranasal Sinuses and Nasal Cavity Treated With Radiotherapy at a Single Institution Over Five Decades: Are We Making Improvement?

    International Nuclear Information System (INIS)

    Purpose: To compare clinical outcomes of patients with carcinomas of the paranasal sinuses and nasal cavity according to decade of radiation treatment. Methods and Materials: Between 1960 and 2005, 127 patients with sinonasal carcinoma underwent radiotherapy with planning and delivery techniques available at the time of treatment. Fifty-nine patients were treated by conventional radiotherapy; 45 patients by three-dimensional conformal radiotherapy; and 23 patients by intensity-modulated radiotherapy. Eighty-two patients (65%) were treated with radiotherapy after gross total tumor resection. Nineteen patients (15%) received chemotherapy. The most common histology was squamous cell carcinoma (83 patients). Results: The 5-year estimates of overall survival, local control, and disease-free survival for the entire patient population were 52%, 62%, and 54%, respectively. There were no significant differences in any of these endpoints with respect to decade of treatment or radiotherapy technique (p > 0.05, for all). The 5-year overall survival rate for patients treated in the 1960s, 1970s, 1980s, 1990s, and 2000s was 46%, 56%, 51%, 53%, and 49%, respectively (p = 0.23). The observed incidence of severe (Grade 3 or 4) late toxicity was 53%, 45%, 39%, 28%, and 16% among patients treated in the 1960s, 1970s, 1980s, 1990s, and 2000s, respectively (p = 0.01). Conclusion: Although we did not detect improvements in disease control or overall survival for patients treated over time, the incidence of complications has significantly declined, thereby resulting in an improved therapeutic ratio for patients with carcinomas of the paranasal sinuses and nasal cavity

  9. Clinical observation in nasopharyngeal carcinoma (NPC) treated with the anti-EGFR monoclonal antibody followed by helical tomotherapy

    International Nuclear Information System (INIS)

    Objective: To evaluate the clinical outcome and the acute toxicity in nasopharyngeal carcinoma (NPC) treated with tomotherapy followed by the anti-EGFR monoclonal antibody. Methods: Between March 2008 and November 2009, 34 newly diagnosed NPC patients were treated with helical tomotherapy combined with nimotuzumab or cetuximab. All the patients underwent tomotherapy at the dose of 70 Gy/33F for the gross tumor volume (pGTVns) and positive lymphnodes (GTVnd), and 60 Gy/33F for the high risk clinical target volume (PTV1), and 56 Gy/33 F for the low risk clinical target volume (PTV2), respectively. 17 patients in group N were given weekly injection of 200 mg for 6-7 times and 17 patients in group C were given initial dosage 400 mg/m2 followed by subsequent weekly dosage of 250 mg/m2 for 6-7 times. Acute lesions were evaluated with the RTOG/EORTC criteria. Result: The median follow-up time was 22 months. The effective rates (CR + PR) in 3, 6 and 12 months were 14/17, 12/17, 12/17 in group N and 15/17, 14/17, 14/17 in group C. The 1 year survival rate was 15/17 in group Nand 17/17 in group C. Nimotuzumab had less acute mucositis reaction (u=2.25, P< 0.05), weight loss (t=2.56, P=0.02) and rash (u=4.36, P<0.01) compared with cetuximab. Conclusions: Helical tomotherapy combined with nimotuzumab or cetuximab was effective and made no difference in the short-term efficacy and 1 year survival rate for the patients with NPC. Nimotuzumab has less acute reaction than cetuximab. More studies should be done to prove long-term effects. (authors)

  10. Failure patterns and survival in patients with nasopharyngeal carcinoma treated with intensity modulated radiation in Northwest China: A pilot study

    International Nuclear Information System (INIS)

    To evaluate the clinical outcomes and patterns of failure in patients with nasopharyngeal carcinoma (NPC) treated with intensity modulated radiotherapy (IMRT) in Northwest China. From January 2006 to December 2009, 138 NPC patients were treated at Xijing Hospital. Of them, 25 cases with stage I-II received IMRT only, 113 cases with stage III-IVb received IMRT plus accomplished platinum-based chemotherapy. The IMRT prescribed dose was PTV 68-74 Gy to gross disease in nasopharynx and 66-72 Gy to positive lymph nodes in 30-33 fractions, and high risk and low risk region PTV was 60-63 Gy and 50.4~56 Gy in 30~33 and 28 fractions respectively. Plasma Epstein Barr virus (EBV) DNA load was measured before treatment. The clinical toxicities, outcomes and patterns of failure were observed. The median follow up time was 23 months (range 2 to 53 months). EBV infection positive was only 15.9%. Overall disease failure developed in 36 patients, 99% belonged to stage III/IV disease. Among these, there were 26 distant metastases, 6 local recurrence, and 4 regional recurrence. The 3-year local control rate(LCR), distant metastasis-free survival (MFS), disease-free survival (DFS) and the overall survival (OS) was 93.9%, 79.5%, 70% and 83.1% respectively. Multivariate analyses revealed that age and anemia pre-radiotherapy were independent predictors for OS. IMRT with or without chemotherapy can improve the long term survival of NPC patients in Northwest China. Distant metastasis becomes the main cause of treatment failure. Age and anemia before radiotherapy were the main prognosis factors of NPC patients

  11. Oropharyngeal squamous cell carcinoma with known human papillomavirus status treated with definitive chemoradiotherapy: patterns of failure and toxicity outcomes

    International Nuclear Information System (INIS)

    Tumor human papillomavirus (HPV) status has emerged as one of the most powerful prognostic factors for disease control and survival in patients with oropharyngeal squamous cell carcinoma (OPSCC). We reviewed our experience in patients with OPSCC and known tumor HPV status treated with definitive chemoradiotherapy (CRT). Patients with stage III-IVb OPSCC and known tumor HPV status treated with CRT between 2006 and 2011 were identified from an IRB approved registry for this retrospective review. Outcomes were estimated using the Kaplan-Meier method and compared between HPV-positive and negative patients using the log-rank test. Of the 121 pts (89% male, 93% Caucasian) included in this study, median age was 57 (range: 40–73) and median follow-up was 21 months (range: 6–63). Ninety-seven (80%) patients were HPV-positive and 24 (20%) were HPV-negative. Primary site was base of tongue (55%), tonsil (44%), and oropharyngeal wall (2%). Two year rates of locoregional recurrence (3% vs. 26%; p = 0.002), disease free survival (93% vs. 64%; p = 0.001) and overall survival (94% vs 73%; p = 0.002) were superior in HPV-positive patients, while rates of distant recurrence were similar (3% vs. 5%; p = 0.98). While acute toxicities were similar between both groups, patients with HPV-positive disease were more likely to resume a normal diet (90% vs. 65%; p = 0.017) at last follow up. Also, no HPV-positive patient required a feeding tube beyond 6 months after treatment, compared with 24% of HPV-negative patients. Definitive CRT produces excellent rates of disease control with minimal late toxicity for patients with HPV-positive OPSCC. Studies of OPSCC should account for tumor HPV status when identifying factors prognostic for outcome

    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.

    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).

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.

  14. CT-guided radiofrequency ablation after with transarterial chemoembolization in treating unresectable hepatocellular carcinoma with long overall survival improvement

    International Nuclear Information System (INIS)

    Purpose: To assess the time to disease progression (TTP), long-term survival benefit and safety of patients with unresectable hepatocellular carcinoma (HCC) treated with computed tomography (CT)-guided radiofrequency ablation (RFA) with transarterial chemoembolization chemoembolization (TACE). Methods: This study was approved by the institutional review board. We reviewed the records of patients with intermediate and advanced HCC treated with CT-guided RFA with TACE between January 2000 and December 2009. Median TTP, overall survival (OS) and hepatic function were analyzed with the Kaplan–Meier method and log-rank tests. Results: One hundred and twenty-two patients (112 men and 10 women, mean age 53 years, range 18–86 years) were included in the study. The median follow-up time was 42 months (range 6–89 months), TTP was 6.8 months, the median OS was 31 months, and the 1-, 3-, and 5-year OS were 88.5%, 41.0%, and 10.7%. The results of the univariate analysis revealed that intrahepatic lesion, AJCC stage, and Child-Pugh stage were predictors of OS (P < 0.01). In the multivariate analysis, the AJCC stage system showed a statistically significant difference for prognosis. Procedure-related death was 0.21% (1/470) within 1 month, and a statistical difference was found between the TACE and RFA of liver decompensation and Child-Pugh stage (P < 0.05). Conclusions: The survival probabilities of OS increased with CT-guided RFA with TACE, as observed in randomized studies from Europe and Asia. The longest TTP was observed for the intermediate stage HCC. The procedures were well tolerated with acceptable minor and major complications in unresectable HCC patients

  15. 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

  16. Predictive estimate of effective dose to family members from patients of thyroid carcinoma treated with radioiodine

    International Nuclear Information System (INIS)

    The radiation dose received by any member of the family attending to the patient released after 131I therapy, primarily will be influenced by the whole body activity retained by the patient, the effective half-life of 131I in the body and the length and proximity of contact with the patient i e. the occupancy factor. According to International Commission of Radiological Protection (ICRP 60), the annual effective dose limit for the members of the public is 1 mSv. In the reports available of the doses received by the family members from patients treated with 131I, the doses either have been estimated using dosimeters worn by the relatives for a specific time period or have been theoretically calculated considering physical decay of the radionuclide. In the present study, the likely doses to the family members were estimated based on calculations, wherein the actual effective half-life of 131I and whole body activity of 131I have been used. Two distances (0.6 m and 1 m) and 4 different occupancy factors (0.125, 0.25, 0.75 and 1), were considered for these calculations. In India, the patient is released from the hospital when the whole body 131I activity is less than or equal to 555 MBq (15 mCi), a limit stipulated by AERB. The objective of retaining the patient in the hospital till the whole body retained activity has fallen below the recommended limit is to minimize the radiation exposure to the general public and family members. Our predictive estimated values of effective dose suggests that with proper instructions of radiation safety and hygiene to the patient, doses to the family members and public can be kept below the limit of 1 mSv. Since some individuals in the family will be knowingly and willingly involved in the care, support and comfort of the patient, a dose of more than 1 mSv is acceptable, however, it should be constrained so that it does not exceed 5 mSv.

    Purpose To evaluate transarterial chemoembolization (TACE) use prior to and concomitantly with sorafenib in patients with unresectable hepatocellular carcinoma (HCC) across different global regions. Materials and Methods GIDEON is an observational registry study of more than 3000 HCC patients. Patients with histologically, cytologically, or radiographically diagnosed HCC, and for whom a decision had been made to treat with sorafenib, were eligible. Patients were enrolled into the registry from 39 countries beginning in January 2009, with the last patient follow-up in April 2012. Detailed data on treatment history, treatment patterns, adverse events, and outcomes were collected. All treatment decisions were at the discretion of the treating physicians. Documented approval from local ethics committees was obtained, and all patients provided signed informed consent. Descriptive statistics, including minimum, median, and maximum, were calculated for metric data, and frequency tables for categorical data. Kaplan-Meier estimates with 95% confidence intervals were calculated for survival end points. Results A total of 3202 patients were eligible for safety analysis, of whom 2631 (82.2%) were male. Median age was 62 years (range, 15-98 years). A total of 1511 (47.2%) patients underwent TACE prior to sorafenib; 325 (10.1%) underwent TACE concomitantly. TACE prior to sorafenib was more common in Japan and Asia-Pacific compared with all other regions (362 [71.3%] and 560 [60.3%] vs 12-209 [13.3%-37.1%]). Adverse events were reported in 2732 (85.3%) patients overall, with no notable differences in the incidence of adverse events, regardless of TACE treatment history. Overall survival was 12.7 months in prior-TACE patients, 9.2 months in non-prior-TACE patients, 21.6 months in concomitant-TACE patients, and 9.7 months in non-concomitant-TACE patients. Conclusion Global variation exists in TACE use in sorafenib-treated HCC patients. The combination of TACE with sorafenib appears

  20. Follow-up neurological evaluation in patients with small cell lung carcinoma treated with prophylactic cranial irradiation and chemotherapy

    International Nuclear Information System (INIS)

    The safety of prophylactic cranial irradiation (PCI) has recently been questioned, based on reports of computerized tomographic abnormalities mainly seen in children, who received PCI and chemotherapy, primarily for acute lymphocytic leukemia. In order to clarify the significance of these findings, we examined a series of adult patients who were long term survivors (18 to 48 months, median 26 months, after all treatment). These patients were treated with combination radiotherapy and chemotherapy for small cell lung carcinoma and received cranial irradiation in the absence of known brain involvement by tumor. Patients were divided into three groups: three patients who received PCI + intrathecal methotrexate (MTX) (Group 1), and ten who received only PCI (Group 2). An additional three patients (Group 3) were identified as long term survivors (41 to 70 months after all treatments) of a similar treatment program without any central nervous system (CNS) prophylaxis. All patients received an extensive evaluation of a variety of clinical parameters, EEG, and computer tomography (CT). Although CT abnormalities were detectable (mild cerebral atrophy in eight patients, encephalomalacia in one of the 13 patients with CNS prophylaxis, and mild atrophy in two of the three patients without CNS prophylaxis), no significant clinical abnormalities or EEG changes were detectable. While this group of patients is small, it is a unique cohort: adults who have received cranial irradiation in the absence of known brain tumor with long term follow-up. The precise role of CNS prophylaxis in the etiology of CT abnormalities is unclear, and the lack of clinically significant changes would suggest no contraindication to PCI when indicated

    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

    Some patients with advanced hepatocellular carcinoma (HCC) progressing under sorafenib remain eligible for further systemic therapy. Little is known on the feasibility of systemic treatment beyond sorafenib in this setting. Consecutive HCC patients pre-treated with sorafenib received gemcitabine 1,000 mg/m² and oxaliplatin 100 mg/m² every 14 days. Exclusion criteria included Child C cirrhosis, PS≥3, creatinine clearance54 μmol/L. Pre-treatment body composition was evaluated by CT scan to detect muscle wasting (sarcopenia). The primary evaluation criterion was safety. Secondary evaluation criteria were response rate, and progression-free (PFS) and overall survival (OS). Eighteen patients (median age: 64 years, range 25-77) received a total of 90 cycles (median per patient: 4, range 1-16). Eight patients (44.4 %) had a PS of 2, 5 (27.8%) had Child-Pugh B cirrhosis and 13 (72.2%) had a CLIP score>3. The most frequent toxicities were thrombocytopenia (grade 2-4: n=7, 38.9%) and peripheral neuropathy (grade 2-3: n=7, 38.9%). The overall response rate was 18.8% (95% CI: 0-37.9), and another 18.8 % of patients had stable disease. The median PFS and OS were 3.2 (95% CI: 2.3-3.9) and 4.7 (95% CI: 3.8-8.1) months, respectively. Overall survival was significantly longer in patients without sarcopenia [10.0 months (95% CI: 7.0-13.8) vs. 3.0 months (95 % CI: 2.5-3.9), p<0.001] and in patients with an ECOG PS<2 [8.1 months (95% CI: 7.0-13.8) vs. 3.8 months (95% CI: 2.5-3.9), p=0.017]. In our experience, gemcitabine-oxaliplatin was feasible and had detectable clinical activity in HCC patients pre-treated with sorafenib. Further studies are needed to confirm these findings.

Carcinomas of the floor of mouth treated by exclusive irradiation have a rather good prognosis and the number of grade 2 and 3 complications remains acceptable. Exclusive brachytherapy is preferable to the combination of EBI plus brachytherapy for T1T2N0

    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

  5. 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.

    Among women diagnosed with ductal carcinoma in situ (DCIS), we identified factors associated with local invasive cancer (LIC) and regional/metastatic invasive cancer (RMIC) and provide 10-year risks based on clinically relevant factors. We created a retrospective, population-based cohort of 1492 women with an initial diagnosis of DCIS (1983-1996) treated by lumpectomy alone. Histological and molecular markers (Ki67, ER, PR, COX-2, p16, ERBB2) were collected on DCIS cases with a subsequent tumor (DCIS, LIC, or RMIC) and a subsample of frequency-matched controls without subsequent tumors. Competing risks methods were used to identify factors associated with LIC and RMIC and cumulative incidence methods to estimate 10-year risks for combinations of factors. Median follow-up time was 12.6 years (range 0.5-29.5 years). The overall 10-year risk of LIC (11.9 %) was higher than for RMIC (3.8 %). About half of women with initial DCIS lesions are detected by mammography and p16 negative and have a 10-year risk of LIC of 6.2 % (95 % CI 5.8-6.8 %) and RMIC of 1.2 % (95 % CI 1.1-1.3 %). Premenopausal women whose DCIS lesion was p16 positive or p16 negative and detected by palpation had high 10-year risk of LIC of 23.0 % (95 % CI 19.3-27.4 %). Ten-year risk of RMIC was highest at 22.5 % (95 % CI 13.8-48.1 %) for those positive for p16, COX-2, and ERRB2, and negative for ER, but prevalence of this group is low at 3 %. Ten-year risk of LIC and RMIC is low for the majority diagnosed with DCIS. Combinations of molecular markers and method of detection of initial DCIS lesion can differentiate women at low and high risk of LIC and RMIC. PMID:27146587

    Full Text Available Metastatic lesions to the oral cavity are rare and constitute 1% of all oral lesions. Soft tissues in the oral cavity are less commonly affected when compared with bone. In males, lung is the most common primary site, and the overall survival is low. We present a case of sarcomatoid carcinoma (spindle cell carcinoma of lung that developed metastasis to the tongue alone soon after completing radical treatment. Immunohistochemistry plays a major role in differentiating a primary tongue lesion from a metastatic lesion.

  11. Treatment duration as a prognostic factor for local control and survival in epidermoid carcinomas of the tonsillar region treated by combined external beam irradiation and brachytherapy

    International Nuclear Information System (INIS)

    Purpose: We wanted to study the influence of the time factor in a combination of external irradiation and brachytherapy from a retrospective study of 370 squamous cell carcinomas of soft palate and tonsil. Patients and methods: From 1977 to 1993, 370 soft palate and tonsillar carcinomas were treated at the Centre Alexis Vautrin. All patients received external irradiation (ERT) with a minimum dose to the tumour of 45 Gy, followed by low dose rate brachytherapy by Iridium 192 using the technique of plastic tubes; 22 patients received neo-adjuvant chemotherapy. We treated 85 T1, 159 T2, 117 T3 and nine T4 or TX carcinomas; 128 of these had palpable nodes. There were 267 men and 24 women. The median age was 55 years (range 33-81 years). Results: The median duration of the total treatment was 57 days. The rate of local control was 88% at 5 years when the treatment time was 7 weeks and 74% when it was 9 weeks (P = 0.001). The rates of overall survival at 5 years were 63 and 44%, respectively (P < 0.0001). For the interval between external irradiation and brachytherapy the series was divided into three groups, i.e. patients treated with a delay inferior or equal to 16 days (2 weeks), patients for which the interval was between 16 and 20 days and patients treated with a delay greater than 20 days (3 weeks). The rates of local control and overall survival at 5 years were not significantly different in the two first groups so we amalgamated these two groups and compared them with the third group. In this way the time cut-off for the delay between external irradiation and brachytherapy was 20 days. At 5 years, the rate of local control was 85% for the group for which the interval was inferior to 3 weeks and 73% when the delay was greater (P = 0.01). The rates of overall survival at 5 years were 59 and 38%, respectively (P < 0.001). Multivariate analysis confirmed that protraction of treatment was a factor for poorer local control. This factor was independent of the other

    Conclusion: Pathological parameters like type of tumor, presence of LVE and tumor necrosis in the core biopsy can predict the response to NACT in routine stain. Tumor necrosis and type of breast carcinoma are predictive parameters for tumor responsiveness to NACT. LVE was reliable in predicting axillary lymph node metastasis.

  14. Distribution of protoporphyrin IX in Bowen's disease and basal cell carcinomas treated with topical 5-aminolaevulinic acid

    Science.gov (United States)

    Roberts, David J.; Stables, G. I.; Ash, D. V.; Brown, Stanley B.

    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.

  15. 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)

  16. 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

  17. Carcinoma of the bladder category T3M0, treated using external irradiation combined with radium implantation

    International Nuclear Information System (INIS)

    Experiments using a combination of external irradiation and radium implantation for the treatment of carcinoma of the bladder are described. It is hoped to combine the favourable radiation effects on the lymphatic gland metastases with the preservation of the bladder from implanting radium in the primary tumour. The survival percentages after 40 months are higher than for either of the techniques used alone. (C.F.)

    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.

  19. Risk factors of distant metastasis in patients with squamous cell carcinoma of the uterine cervix treated with postoperative irradiation

    International Nuclear Information System (INIS)

    This paper reports the results of a study of risk factors for recurrence in non-irradiated sites in patients with squamous cell carcinoma of the uterine cervix who received postoperative irradiation. It also discusses clinical experience with such patients, particularly those with a poor prognosis, based on a review of the literature. The study was conducted at the National Shikoku Cancer Center in 62 patients with squamous cell carcinoma of the uterine cervix (mean age=50.5, range=30-66) who received 10 MeV postoperative irradiation with a Linac between 1981 and 1990. An analysis was performed in terms of sites and times of recurrence, risk factors for distant metastasis, and groups at high risk for distant metastasis. Based on the results of the study as well as the review of the literature, it was concluded that squamous cell carcinoma of the uterine cervix is sensitive to radiation therapy and that the clinical outcome of local treatment is satisfactory. However, systemic chemotherapy should be considered for patients who are suspected of having minute distant metastasis at the time of surgical operation, i.e., those with moderate to severe vascular space invasion, multiple lymph node metastasis, parametrium infiltration, and/or endometrial infiltration.

  20. Long-term Outcomes and Quality of Life of 186 Patients With Primary Parotid Carcinoma Treated With Surgery and Radiotherapy at the Daniel den Hoed Cancer Center

    International Nuclear Information System (INIS)

    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

  2. Impact of adjuvant chemotherapy on cosmesis and complications in Stages I and II carcinoma of the breast treated by biopsy and radiation therapy

    International Nuclear Information System (INIS)

    Cosmesis and complication rates were examined in patients with early stage carcinoma of the breast treated by biopsy and radiation therapy with and without adjuvant chemotherapy in an attempt to determine the effect of chemotherapy upon these parameters. Between April 1, l975 and June 1, 1980, 51 patients were treated with radiation therapy and adjuvant chemotherapy (XRT + ACT) and 83 patients with radiotherapy alone (XRT). Cosmetic results deteriorated with time in both groups but to a greater extent in the XRT + ACT group. Comparison of the two treatment groups revealed that complication rates were significantly incresed in the XRT + ACT group. Of the 51 patients in the XRT + ACT group, 21 patients (41%) suffered complications compared to 8 (10%) of the 83 patients in the XRT group. This difference in complication rates resulted primarily from an increased incidence in the XRT + ACT group of wet desquamation in the electron beam portal used to treat the internal mammary lymph nodes and a trend towards a higher incidence of spontaneous nonpathologic rib fractures, myositis and arm edema. The authors' preliminary conclusions are that adjuvant chemotherapy has a negative impact upon cosmesis and complications rates in patients being treated with definitive radiotherapy. However, cosmetic results remain satisfactory and complication rates are maintained at an acceptable level

  3. MVP expression in the prediction of clinical outcome of locally advanced oral squamous cell carcinoma patients treated with radiotherapy

    International Nuclear Information System (INIS)

    To explore the role of Major Vault Protein (MVP) in oral cavity squamous cell carcinoma patients. 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. 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. 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

  5. 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

  6. Psychoeducational group increases vaginal dilation for younger women and reduces sexual fears for women of all ages with gynecological carcinoma treated with radiotherapy

    International Nuclear Information System (INIS)

    Purpose: The association between radiotherapy for gynecological carcinoma and sexual dysfunction is well established. Regular vaginal dilation is widely recommended to these women as a way for them to maintain vaginal health and good sexual functioning. However, the compliance rate with this recommendation is low. The purpose of this study was to test the effectiveness of a group psychoeducational program based on the 'information-motivation-behavioral skills' model of behavior change in increasing the rate of compliance. Methods and Materials: Thirty-two women with Stage I or II cervical or endometrial carcinoma who were being treated with radiotherapy were randomized and received either the experimental group program or the control intervention that consisted of written information and brief counseling. Outcome measures included global sexual health, knowledge about sexuality and cancer, fears about sexuality after cancer, and vaginal dilation compliance. Results: Younger women attending the experimental program (44.4%) were significantly more likely to follow recommendations for vaginal dilation than those who received the control intervention (5.6%). Women, regardless of age, who received the experimental intervention reported less fear about sex after cancer treatment. The older women who received the experimental intervention gained more sexual knowledge. There was no evidence that the experimental intervention improved global sexual health. Conclusions: This is the first controlled study to provide evidence of an intervention's effectiveness 1. in increasing women's vaginal dilation following radiotherapy for gynecological carcinoma and 2. in reducing their fears about sex after cancer. Most women, particularly younger women, are unlikely to follow the recommendation to dilate unless they are given assistance in overcoming their fears and taught behavioral skills

    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.

  9. Interplay Between Oncoproteins and Antioxidant Enzymes in Esophageal Carcinoma Treated Without and With Chemoradiotherapy: A Prospective Study

    International Nuclear Information System (INIS)

    Purpose: To analyze p53, bcl-2, c-myc, and cyclooxygenase-2 protein expression changes and examine their relationship with various antioxidant enzymes in esophageal carcinoma patients. Methods and Materials: Patients in Group 1 underwent transhiatal esophagectomy and those in Group 2 were administered chemoradiotherapy followed by surgery after 4 weeks of neoadjuvant therapy. Results: The relationship analysis among the various protein markers and antioxidant enzymes showed an inverse correlation between bcl-2 and superoxide dismutase/catalase in tumor tissues, irrespective of the treatment arm followed. An important positive association was observed between bcl-2 and reduced glutathione levels in the tumor tissue of patients receiving neoadjuvant therapy. Another apoptosis-modulating marker, c-myc, in the tumor tissue of Group 2 patients showed similar pattern levels (high and low) as that of superoxide dismutase/catalase. The association of cyclooxygenase-2 and p53 with various antioxidant enzymes showed a significant positive correlation between cyclooxygenase-2 expression and catalase activity and an inverse trend between p53 expression and superoxide dismutase and catalase activity in the tumor tissue of patients given neoadjuvant therapy. In addition, patients with overexpressed p53 protein levels had lower glutathione peroxidase enzyme levels and vice versa in the tumor tissue of patients who had undergone surgery as their main mode of treatment. Conclusion: The results of this study broaden the insight into the relationships shared among oncoproteins and the antioxidant defense system, and this could be helpful in the clinical management of esophageal carcinoma

    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.

    We report a case of squamous cell carcinoma of external auditory canal in an Omani man with oculocutaneous albinism. The disease mimicked inflammatory process revealing positive cultures for various microorganisms during the course of his illness. He was eventually biopsied to rule out atypical infective process or presence of malignancy. He was staged as T4N0M0 and treated with radical doses of palliative radiation therapy which was very well tolerated and resulted in a complete resolution of disease clinically and a major soft tissue response on radiological imaging. Another unique finding was the absence of epidermal growth factor receptor (EGFR) protein overexpression in the tumour specimen. More than 90% of mucosal squamous cell carcinoma (SCC) involving the head and neck region overexpress the EGFR protein in normal skin patients. SCC is the predominant cutaneous malignancy in albinos, and the presence of EGFR protein overexpression in cutaneous SCC is believed to be 56–58% in normal skin patients. The scientific literature is scarce on reporting incidence of EGFR overexpression in either cutaneous or mucosal SCC in albinos, and it remains to be defined whether being albino is the cause for its absence.

    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

  13. Time course and incidence of late complications in patients treated with radiation therapy for FIGO Stage IB carcinoma of the uterine cervix

    International Nuclear Information System (INIS)

    Purpose: To determine the time course and incidence of late complications from radiation therapy in patients treated with radiation for FIGO Stage IB carcinoma of the uterine cervix, and to evaluate patient and tumor factors associated with an increased probability of treatment complications. Methods and Materials: The medical records of 1784 patients with FIGO Stage IB cervical carcinoma who were treated with initial radiation therapy between 1960 and 1989 were retrospectively reviewed. Follow-up was obtained from clinic visits and correspondence with patients and their physicians. Treatment complications were graded retrospectively. Complication rates were calculated actuarially; patients who died of disease or intercurrent illness without experiencing a major complication were censored at the time of death. There were 1241, 924, 548, and 274 patients followed for more than 5, 10, 15, and 20 years, respectively. Results: Of patients treated for Stage IB cervical carcinoma, 7.7% and 9.3% had experienced major (≥Grade 3) complications at 3 and 5 years, respectively. After 5 years, there was a small but continuous risk of approximately 0.34% per year, resulting in an overall actuarial risk of having had major complications of 14.4% at 20 years. The risk of developing major urinary tract complications was approximately 0.7% per year for the first 3 years of follow-up, decreasing to about 0.25% per year for at least 25 years. In contrast, the risk of developing rectal complications was about 1% per year during the first 2 years, with a subsequent sharp decline to about 0.06% per year between Years 2 and 25. The risk of fistula formation was approximately doubled in the 234 patients who underwent adjuvant extrafascial hysterectomy (5.3 vs. 2.6% at 20 years; p = 0.04) and in the 111 patients who had pretreatment laparotomy (5.2 vs. 2.9%; p = 0.007). The risk of developing small bowel obstruction was increased in patients who underwent pretreatment laparotomy (14.5 vs

    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

    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.

  16. Incidence of bowel wall oedema on computed tomography exams and association with diarrhoea in renal cell carcinoma patients treated with sunitinib

    International Nuclear Information System (INIS)

    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.)

    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

  1. The effect of local control on metastatic dissemination in carcinoma of the prostate: Long-term results in patients treated with 125I implantation

    International Nuclear Information System (INIS)

    The study evaluates the effect of the locally recurring tumor on the incidence of metastatic disease in early stage carcinoma of the prostate. The probability of distant metastases was studied in 679 patients with Stage B-C/N0 carcinoma of the prostate treated at MSKCC between 1970 and 1985 (median follow-up of 97 months). Patients were staged with pelvic lymph node dissection and treated with retropubic 125I implantation. The actuarial distant metastases free survival (DMFS) for patients at risk at 15 years after initial therapy was 37%. Cox proportional hazard regression analysis of covariates affecting the metastatic outcome showed that local failure, used in the model as a time dependent variable, was the most significant covariate, although stage, grade, and implant volume were also found to be independent variables. The relative risk of metastatic spread subsequent to local failure was 4-fold increased compared to the risk without evidence of local relapse. The 15-year actuarial DMFS in 351 patients with local control was 77% compared to 24% in 328 patients who developed local relapses (p less than 0.00001). The relation of distant spread to the local outcome was observed regardless of stage, grade, or implant dose. Even stage B1/N0-Grade I patient with local control showed a 15-year actuarial DMFS of 82%, compared to 22% in patients with local relapse (p less than 0.00001). The median local relapse-free survival (LRFS) in the 268 patients with local recurrences who did not receive hormonal therapy before distant metastases were detected was 51 months, compared to a median of 71 months for DMFS in the same patients (p less than 0.001), consistent with the possibility that distant dissemination may develop secondary to local failure

  2. Prognostic stratification of patients with advanced renal cell carcinoma treated with sunitinib: comparison with the Memorial Sloan-Kettering prognostic factors model

    International Nuclear Information System (INIS)

    The treatment paradigm in advanced renal cell carcinoma (RCC) has changed in the recent years. Sunitinib has been established as a new standard for first-line therapy. We studied the prognostic significance of baseline characteristics and we compared the risk stratification with the established Memorial Sloan Kettering Cancer Center (MSKCC) model. This is a retrospective analysis of patients treated in six Greek Oncology Units of HECOG. Inclusion criteria were: advanced renal cell carcinoma not amenable to surgery and treatment with Sunitinib. Previous cytokine therapy but no targeted agents were allowed. Overall survival (OS) was the major end point. Significance of prognostic factors was evaluated with multivariate cox regression analysis. A model was developed to stratify patients according to risk. One hundred and nine patients were included. Median follow up has been 15.8 months and median OS 17.1 months (95% CI: 13.7-20.6). Time from diagnosis to the start of Sunitinib (<= 12 months vs. >12 months, p = 0.001), number of metastatic sites (1 vs. >1, p = 0.003) and performance status (PS) (<= 1 vs >1, p = 0.001) were independently associated with OS. Stratification in two risk groups ('low' risk: 0 or 1 risk factors; 'high' risk: 2 or 3 risk factors) resulted in distinctly different OS (median not reached [NR] vs. 10.8 [95% confidence interval (CI): 8.3-13.3], p < 0.001). The application of the MSKCC risk criteria resulted in stratification into 3 groups (low and intermediate and poor risk) with distinctly different prognosis underlying its validity. Nevertheless, MSKCC model did not show an improved prognostic performance over the model developed by this analysis. Studies on risk stratification of patients with advanced RCC treated with targeted therapies are warranted. Our results suggest that a simpler than the MSKCC model can be developed. Such models should be further validated

    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.

  6. Persisting cyclical uterine bleeding in patients treated with radical radiation therapy and hormonal replacement for carcinoma of the cervix

    International Nuclear Information System (INIS)

    Radical radiation therapy used for carcinoma of the cervix will ablate ovarian function. Since January 1986, our policy has been to administer oral combination oestrogen-progesterone replacement hormonal therapy to all premenopausal patients undergoing radical radiation with or without synchronous chemotherapy, for invasive cervix cancer. Five out of 22 (23%) such patients unexpectedly experienced between one and four episodes of cyclical per vaginal bleeding after the completion of radiation therapy. Bleeding episodes occurred in the absence of persistent tumor or radiation reaction, and suggest persisting endometrial response to exogenous hormonal stimulation. Uterine activity was temporarily retained in these five patients despite a minimal endometrial surface dose of between 4800 and 6490 cGy. The limited number of cycles before bleeding spontaneously ceased may represent the slow death of endometrial cells subsequent to radiation or radiochemotherapy treatment, and has not previously been described. In view of the paucity of data on the radiosensitivity of normal endometrium, we have carefully examined these patients who appear to have retained endometrial sensitivity to hormonal stimuli after radical radiation-chemotherapy for uterine cervix cancer

    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.

    Full Text Available Background: Adenoid cystic carcinoma (ACC accounts for 1% of all head and neck (HN cancers. Materials and Methods: Demographic, clinical, treatment, and survival details of 66 patients were collected (1995-2011 and analyzed. Disease-free survival (DFS was estimated by Kaplan-Meier method. Results: Primary disease sites were sinonasal (n = 27, salivary gland (n = 30, and others (n = 9. Median follow-up was 23 months (range: 12-211 months. Estimated DFS at 2- and 5-year were 75% and 67.2%, respectively. On univariate analysis, intra-cranial extension (ICE (hazard ratio [HR]: 3.59, P = 0.0071, lymph node involvement (HR: 4.05, P = 0.0065, treatment modality (others vs. surgery plus adjuvant radiotherapy, HR: 2.39, P = 0.0286 and T stage (T3/4 vs. T1/2, HR: 3.27, P = 0.007 had significant impact on DFS. Lymph node involvement (P = 0.038 and ICE (P = 0.038 continued to have significant impact on DFS on multivariate analysis. Conclusion: Surgery followed by adjuvant radiotherapy remains the treatment of choice for HN ACC. Lymph node involvement and ICE confer poor prognosis.

    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.

  10. Use of serum squamous cell carcinoma antigen for follow-up monitoring of cervical cancer patients who were treated by concurrent chemoradiotherapy

    International Nuclear Information System (INIS)

    To investigate the significance of monitoring the levels of the serum squamous cell carcinoma antigen (SCC-Ag) for the detection of recurrent disease in patients with cervical cancer treated by concurrent chemoradiotherapy. The records of 112 patients with cervical cancer were reviewed. Serum SCC-Ag levels were measured at regular follow-up visits. A SCC-Ag level of 2 ng/mL was considered the upper limit of normal. Biochemical failure was defined as two consecutively increasing SCC-Ag values above normal. Recurrent disease was confirmed by histologic and radiographic studies. Eighteen patients (16%) developed recurrent disease. Sixteen patients had initially elevated SCC-Ag, post-treatment normalization of SCC-Ag, and tumor recurrence. The SCC-Ag difference (ΔSCC-Ag), defined as the difference between the last value after two consecutively increases above normal and the value immediately before the elevation, had good clinical performance in predicting cancer recurrence. The cutoff value of ΔSCC-Ag was 0.95 ng/mL. SCC-Ag is a relatively good method for the detection of disease recurrence in patients with cervical cancer who were treated by concurrent chemoradiotherapy

    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

METHODS The study comprised of audiological evaluation of 60 patients prior to and at the completion of treatment using pure tone audiometry. RESULTS At the end of 6 weeks, incidence of SNHL found to be 65.38% seen in patients who have not received Vitamin E supplement as compared to incidence of 10% seen in patients treated with CRT along with Vitamin E seen at higher frequencies and significant otoprotection offered by Vitamin E supplement was observed at 8kHz. DISCUSSION The possible mechanism for hearing loss are discussed and compared with the result of such studies in literature. CONCLUSION There is definitive benefit of oral Vitamin E supplement in preventing this hearing loss, more so at higher frequencies.

  13. 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

    Full Text Available Everolimus is an orally administered inhibitor of the mammalian target of rapamycin (mTOR recommended for patients with metastatic renal cell carcinoma (mRCC who progressed on previous vascular endothelial growth factor (VEGF receptor-tyrosine kinase inhibitor therapy. Efficacy of everolimus in patients who progressed on anti-VEGF monoclonal antibody bevacizumab is unknown. We did a multicenter prospective trial of everolimus in patients with mRCC whose disease had progressed on bevacizumab ± interferon alpha (IFN. Patients with clear-cell mRCC which had progressed on bevacizumab ± IFN received everolimus 10 mg once daily. The primary end point was the proportion of patients remaining progression-free for 56 days, and a two-stage Simon design was used, with 80 % power and an alpha risk of 5 %. This study is registered with ClinicalTrials.gov, number NCT02056587. From December 2011 to October 2013, a total of 37 patients (28 M, 9 F were enrolled. Median age was 60.5 years (range 41-66, 11 % had Eastern Cooperative Oncology Group Performance Status (ECOG PS > 2, and Memorial Sloan-Kettering Cancer Center (MSKCC favorable/intermediate risk was 38/62 %. Five (14 % patients had a confirmed partial response and 26 (70 % patients had a stable disease. Median progression-free survival was 11.5 months (95 % CI, 8.8–14.2. Median overall survival was not reached. No grade 3 or 4 treatment-related toxicities were observed. The most common grade 2 adverse events were fatigue (19 % and pneumonitis (8 %. Everolimus demonstrated a favorable toxicity profile and promising anti-tumor activity as a second-line therapy in metastatic renal cell carcinoma (RCC patients previously treated with bevacizumab ± IFN.

    Full Text Available Aim: To report the outcome of carcinoma of the uterine cervix patients treated radically by external beam radiotherapy (EBRT and high-dose-rate (HDR intracavitary radiotherapy (ICRT. Materials and Methods: Between January 1997 to December 2001, a total of 550 newly diagnosed cases of carcinoma of the uterine cervix were reported in the department. All cases were staged according to the International Federation of Gynecologists and Oncologists (FIGO staging system, but for analytical convenience, the staging was limited to stages I, II, III, and IV. 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.

  16. Incorporating biologic measurements (SF2, CFE) into a tumor control probability model increases their prognostic significance: a study in cervical carcinoma treated with radiation therapy

    International Nuclear Information System (INIS)

    Purpose: To assess whether incorporation of measurements of surviving fraction at 2 Gy (SF2) and colony-forming efficiency (CFE) into a tumor control probability (tcp) model increases their prognostic significance. Methods and Materials: Measurements of SF2 and CFE were available from a study on carcinoma of the cervix treated with radiation alone. These measurements, as well as tumor volume, dose, and treatment time, were incorporated into a Poisson tcp model (tcpα,ρ). Regression analysis was performed to assess the prognostic power of tcpα,ρ vs. the use of either tcp models with biologic parameters fixed to best-fit estimates (but incorporating individual dose, volume, and treatment time) or the use of SF2 and CFE measurements alone. Results: In a univariate regression analysis of 44 patients, tcpα,ρ was a better prognostic factor for both local control and survival (p2 alone (p=0.009 for local control, p=0.29 for survival) or CFE alone (p=0.015 for local control, p=0.38 for survival). In multivariate analysis, tcpα,ρ emerged as the most important prognostic factor for local control (pα,ρ, CFE was still a significant independent prognostic factor for local control, whereas SF2 was not. The sensitivities of tcpα,ρ and SF2 as predictive tests for local control were 87% and 65%, respectively. Specificities were 70% and 77%, respectively. Conclusions: A Poisson tcp model incorporating individual SF2, CFE, dose, tumor volume, and treatment time was found to be the best independent prognostic factor for local control and survival in cervical carcinoma patients

  19. Does pathologic node status affect local control in patients with carcinoma of the head and neck treated with radical surgery and postoperative radiotherapy?

    International Nuclear Information System (INIS)

    Purpose: To evaluate the effect of pathologic lymph node status and nodal stage on local control at the primary site in patients with advanced squamous cell carcinomas of the head and neck, treated with radical surgery and postoperative irradiation. Methods and Materials: Fifty-seven patients with advanced squamous cell carcinomas of the oral cavity, oropharynx, hypopharynx, larynx, and supraglottic larynx were analyzed. All patients underwent resection of the primary lesion, neck dissection, and postoperative radiotherapy. Minimum follow-up was 2 years. The median dose to the primary tumor bed was 60.4 Gray (range 39.7-72.0). Besides pathologic nodal status (pN0 vs. pN+) and nodal stage, the following factors were analyzed for their impact on local control: age, gender, T stage, tumor grade, resection margins, interval from surgery to irradiation, dose to the primary site, and overall treatment time. Results: The 3-year actuarial local control rate was 78%. When all patients were analyzed, nodal status (pN0 vs. pN+) did not affect control at the primary site (71% vs. 82%, p = 0.42). Nodal stage (pN0-N2a va. pN2b-N2c) was also not a significant factor for local control (74% vs. 82%, p = 0.57). When only patients with negative margins were analyzed, nodal status again did not impact on local control (79% vs. 90% for pN0 vs. pN+, p = 0.39). On univariate analysis, only tumor grade, margin status, and elapsed days were significant factors for local control. Local control was 85% for patients with negative margins vs. 60% for those with positive margins (p = 0.016). For patients with moderately and poorly differentiated tumors, local control was 86% as compared to 50% for patients with well-differentiated tumors (p = 0.007). When radiotherapy was completed within 50 days, local control was 93% as opposed to 63% for >50 days (p 0.016). On multivariate analysis, only margin status (p = 0.002) and tumor grade (p = 0.007) remained significant. Conclusion: We conclude that

  20. Exposure rates (versus time after administration), in relation with clinical factors, for thyroid carcinoma patients treated with Iodine-131

    International Nuclear Information System (INIS)

    While the therapeutic use of iodine-131 for thyroid carcinoma patients offers enormous benefit to them, it contributes also significantly to the radiation exposure of individuals and population. A critical quantity for decisions relating radiation protection system based on restrictions recommended by authorities is the residual I-131 activity in patient's body. When this value is larger than a threshold level, it may keep the patient hospitalised for a short period of usually 2 to 3 days with an additional period of 7 days at home, where he must sleep separately and avoid close contact with other people. Essential for radiation protection issues is the careful collection of radioactive urine, radioactive waste and avoidance of any contaminations by perspiration and saliva. Longer hospital stay would increase the total cost of the treatment and limit the availability of the isolation room. So the patient has then to return home, having always in mind that in spite of the fast washout of the I-131 from his body, even the second week still contributes significantly to the total radiation burden to relatives and friends. Radiation hazards concerning relatives and friends can be kept to a truly negligible level (a small fraction of the annual dose limit of only 1mSv), only if it is provided that: a) reasonable standards of personal hygiene and cleanliness are followed, b) urine or saliva contaminations are avoided and c) patient's close contact with relatives or friends is kept to a minimum. These measures should be followed for a time period of 2-8 days after hospital discharge, a period that depends on administered and retained I-131 activity. This work tries to estimate the correlation between several clinical factors and the residual activity of I-131 in patient's body and proposes a method for a more simple measurement of the total body activity during patient's stay in the treatment centre - hospital

  1. Oropharyngeal Squamous Cell Carcinoma Treated With Radiotherapy or Radiochemotherapy: Prognostic Role of TP53 and HPV Status

    International Nuclear Information System (INIS)

    Purpose: To study the prognostic value of the TP53 mutation and human papilloma virus (HPV) status in oropharyngeal squamous cell carcinoma (OPSCC). Methods and materials: The TP53 mutation and HPV status were analyzed in 78 cases of locoregionally advanced OPSCC. The possible correlation of these factors with locoregiownal control, relapse-free survival, disease-specific survival, and overall survival (OS) was also investigated. Results: Of these 78 cases, 22 had disruptive and 22 had non-disruptive (silent) TP53 mutations; the remaining 34 cases had wild-type (WT) TP53. HPV 16 DNA was found in 9 cases (11%), but all HPV-positive (HPV+) cases carried a functional p53 protein, except for 1 case that had a silent mutation. HPV+ patients fared better than HPV-negative (HPV-) patients in terms of all survival parameters, with highly statistically significant differences between the groups. Specifically, no distant metastases were observed in the HPV+ patients, whereas they occurred in 17% of the HPV- patients. However, no difference was observed between the WT TP53 and mutation group, even when this was analyzed in terms of disruptive and non-disruptive mutations. Regardless, treatment with chemotherapy nearly doubled the 5-year OS rates, both in the mutation (42% vs. 22%) and WT (30 vs. 16%) group, but only the mutation group showed improvement in all survival parameters. In addition, the second tumor-free 5-year survival rate was 72% in HPV- cases, but no second tumors were observed in HPV+ and WT p53 cases. Conclusions: Patients with HPV+ OPSCC have an excellent prognosis after radiochemotherapy, but cisplatin-based chemotherapy may not confer a satisfactory outcome, especially in WT cases, thereby justifying the additional or alternative use of taxanes and epidermal growth factor receptors inhibitors. Uncommon distant metastases and second tumors in the HPV+ group may be cause for clinicians to review the follow-up policies in these patients.

  2. Sensorineural hearing loss in patients treated for nasopharyngeal carcinoma: a prospective study of the effect of radiation and cisplatin treatment

    International Nuclear Information System (INIS)

    Purpose: The pattern of sensorineural hearing loss (SNHL) after primary treatment for nasopharyngeal carcinoma (NPC) was studied, and the effect of cisplatin, radiotherapy dose, and fractionation were evaluated. Methods and Materials: One hundred thirty-two patients, 227 ears, and 1100 audiogram reports were analyzed. Methods and Materials: One hundred thirty-two patients, 227 ears, and 1100 audiogram reports were analyzed. Radiotherapy dose ranged from 59.5 to 76.5 Gy. Fifty-two patients received preirradiation cisplatin, total dose 100-185 mg/m2. Serial postirradiation bone conduction thresholds at 0.5 kHz, 1 kHz, 2 kHz, and 4 kHz were compared with pretreatment thresholds at respective frequencies. Increase of at least 15 dB was considered as significant and was further grouped as transient or persistent SNHL. Univariate and multivariate analyses were performed to identify predicting factors for persistent SNHL. Results: At median follow-up of 30 months, 24.2% of ears developed persistent SNHL. High frequency was more affected than low frequencies, 22 vs. 5.3%. Males were more affected than females, 29.4 vs. 15.5%, p = 0.0132. Incidence of persistent SNHL increased with age, with 0, 17.2, and 37.4% of patients aged under 30, between 30-50 and over 50 affected, respectively, p = 0.0001. High incidence was found in patient with postirradiation serous otitis media (SOM), 46.9%. Chemotherapy with cisplatin and radiation dose or fractionation had no significant effect. Multivariate analysis confirmed age, sex, and postirradiation SOM as significant prognostic factors for persistent SNHL. Conclusions: Transient and persistent SNHL occurred after radiotherapy, more commonly affecting high frequency. A low dose of preirradiation cisplatin did not increase the risk. A dose fractionation effect of radiotherapy was not confirmed in this study

    Background: To examine whether nuclear NF-κB expression correlates with outcome in patients with head and neck squamous cell carcinoma (HNSCC) treated with primary chemoradiation therapy (CRT). Methods and Materials: Between 2007 and 2010, 101 patients with locally advanced primary HNSCC were treated with definitive simultaneous CRT. Pretreatment biopsy specimens were analyzed for NF-κB p65 (RelA) nuclear immunoreactivity. A sample was assigned to be positive with more than 5% positive nuclear expression. The predictive relevance of NF-κB and clinicopathologic factors for overall survival (OS), progression-free survival (PFS), local progression-free survival (LPFS), and metastasis-free survival (DMFS) was examined by univariate and multivariate analysis. Results: No significant differences between the groups were observed with regard to age, sex, total radiation dose, fractionation mode, total chemotherapy applied, T stage or grading. Patients with p65 nuclear positive biopsy specimens showed significantly a higher rate of lymph node metastasis (cN2c or cN3 status, P=.034). Within a mean follow-up time of 25 months (range, 2.33-62.96 months) OS, PFS, and DMFS were significantly poorer in the p65 nuclear positive group (P=.008, P=.027, and P=.008, respectively). These correlations remained significant in multivariate analysis. Conclusion: NF-κB/p65 nuclear expression is associated with increased lymphatic and hematogenous tumor dissemination and decreased survival in HNSCC patients treated with primary CRT. Our results may foster further investigation of a predictive relevance of NF-κB/p65 and its role as a suitable target for a molecular-based targeted therapy in HNSCC cancer.

    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.

  7. 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 Abstract Purpose To investigate the outcome of HIV-seropositive patients under highly active antiretroviral treatment (HAART with anal cancer treated with radiotherapy (RT alone or in combination with standard chemotherapy (CT. Patients and methods Clinical outcome of 81 HIV-seronegative patients (1988 – 2003 and 10 consecutive HIV-seropositive patients under HAART (1997 – 2003 that were treated with 3-D conformal RT of 59.4 Gy and standard 5-fluorouracil and mitomycin-C were retrospectively analysed. 10 TNM-stage and age matched HIV-seronegative patients (1992 – 2003 were compared with the 10 HIV-seropositive patients. Pattern of care, local disease control (LC, overall survival (OS, cancer-specific survival (CSS, and toxicity were assessed. Results RT with or without CT resulted in complete response in 100 % of HIV-seropositive patients. LC was impaired compared to matched HIV-seronegative patients after a median follow-up of 44 months (p = 0.03. OS at 5 years was 70 % in HIV-seropositive patients receiving HAART and 69 % in the matched controls. Colostomy-free survival was 70 % (HIV+ and 100 % (matched HIV- and 78 % (all HIV-. No HIV-seropositive patient received an interstitial brachytherapy boost compared to 42 % of all HIV-seronegative patients and adherence to chemotherapy seemed to be difficult in HIV-seropositive patients. Acute hematological toxicity reaching 50 % was high in HIV-seropositive patients receiving MMC compared with 0 % in matched HIV-seronegative patients (p = 0.05 or 12 % in all HIV-seronegative patients. The rate of long-term side effects was low in HIV-seropositive patients. Conclusion Despite high response rates to organ preserving treatment with RT with or without CT, local tumor failure seems to be high in HIV-positive patients receiving HAART. HIV-seropositive patients are subject to treatment bias, being less likely treated with interstitial brachytherapy boost probably due to HIV-infection, and they are at

  9. Outcome and prognostic factors for local recurrence in mammographically detected ductal carcinoma in situ of the breast treated with conservative surgery and radiation therapy

    International Nuclear Information System (INIS)

    Purpose: We have retrospectively reviewed our institution's experience treating a predominantly mammographically detected population of ductal carcinoma in situ (DCIS) patients with conservative surgery and radiation therapy (CSRT) to determine outcome and prognostic factors for local recurrence. Methods and Materials: Between January 1, 1982 and December 31, 1988, 52 consecutive cases of DCIS of the breast were treated with CSRT at William Beaumont Hospital. Forty-six (88%) were mammographically detected nonpalpable lesions. All patients underwent at least an excisional biopsy and 28 (54%) were reexcised. The axilla was surgically staged in 41 (79%) and all were N0. The entire breast was irradiated to 45-50 Gy over 5-6 weeks. The tumor bed was boosted in 49 (94%) so that the minimum dose was 60 Gy. The three patients not boosted received a minimum dose of 50 Gy to the entire breast. Pathologic materials were reviewed by one of the authors. Results: The predominant DCIS pattern was comedo in 40%, cribriform in 28%, solid in 17%, and micropapillary in 15%. The predominant nuclear grade was Grade I in 51%, Grade II in 49%, and Grade III in 0%. The median follow-up is 68 months. There have been three recurrences in the treated breast at a median time to failure of 30 months. The 5- and 8-year actuarial local recurrence rate is 6%. One patient recurred with invasive ductal cancer at 28 months, and the other two recurrences were DCIS at 30 and 50 months. All three patients were treated with salvage mastectomy. The patient who recurred locally with an invasive cancer developed metastasis and died at 64 months. The 5- and 8-year actuarial cause-specific survival rates are 100% and 97%, respectively. The following pathologic factors were analyzed for an association with local recurrence: predominant DCIS histology, predominant nuclear grade, and highest nuclear grade. Of these, the predominant nuclear grade was the best predictor of local recurrence (p = 0.070). No

  10. The study of tumoral, radiobiological, and general health factors that influence results and complications in a series of 448 oral tongue carcinomas treated exclusively by irradiation

    International Nuclear Information System (INIS)

    The aim was to study the different factors that influence the results and complications in a series of 448 carcinomas of the oral tongue treated from January 31, 1972 to December 31, 1986, by brachytherapy(Br)±neck dissection (181 cases) or combination of external beam irradiation and brachytherapy (EBI + Br) (267 cases). The patients distribution was: 125 T1, 186 T2, 128 T3, 9 T4Tx, 78% NO, and 22% N+. The authors used the guide gutter or plastic tubes technique (Paris system dosimetry). Results at 5 and 10 years are: local control 68% and 64%, locoregional control 58% and 53%, specific survival 45% and 39%, and overall survival 44% and 27%. In the unvariate analysis for local control (LC) and overall survival (OS), they considered the tumoral factors. At 5 years, the LC for T1, T2, T3, are 93%, 65%, and 49%, and the OS 69%, 41%, and 25%, respectively. The lesions of the undersurface of the tongue have a better LC (77%) than other localizations (64%). For general factors, the index of general health condition, age, and sex were not significant for LC, but proved significant for OS. Significant radiobiological factors: the safety margin (expressed by the ratio treated surface on tumoral surface ≥1.2) is significant for LC and OS. This is the same if the interval between EBI and Br is ≤ 20 days. Neither the dose rate, the spacing between the sources, the total dose, nor Br dose were significant, but the last two were adapted according to the infiltration. In the univariate study for grade 2 and 3 complications (tissue and bone), the surface treated (>12 cm2), and the dose rate >0.7 Gy/h were significant. The multivariate study showed that the small size of the lesion is the most important factor for local control, with brachytherapy alone for T1T2NO and the number of days between EBI and brachytherapy ≤20 days. For complications, the most important factors are the total dose >80 Gy and a treated surface >12 cm2. 37 refs., 1 fig., 5 tabs

  11. Long-Term Outcome in Patients With Ductal Carcinoma In Situ Treated With Breast-Conserving Therapy: Implications for Optimal Follow-up Strategies

    International Nuclear Information System (INIS)

    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.

  12. Update report of nasopharyngeal carcinoma treated with reduced-volume intensity-modulated radiation therapy and hypothesis of the optimal margin

    International Nuclear Information System (INIS)

    Background and purpose: To establish the minimally required margins in different directions measured from GTV in the definitive treatment of nasopharyngeal carcinoma (NPC) using IMRT based on the 5-year results. Methods and materials: Between November 2003 and May 2007, 414 patients with non-metastatic NPC were treated with IMRT according to our institutional protocol. Treatment outcomes at 5 years were analyzed. Distances from GTV-T to CTV2 (i.e., CTV 59.4 Gy) in 6 directions (anterior, posterior, superior, inferior, and bilateral) were measured and analyzed. Results: The 5-year estimated overall survival (OS), disease free survival (DFS), local control (LC) were 80%, 77% and 95%, respectively. For the margins measured from GTV-T to CTV2, margins used with T4 disease were significantly and uniformly smaller than the whole group in all the 6 directions (P = 0.000, 0.000, 0.000, 0.000 and 0.046, respectively). However, no increase of local recurrence was associated to this limited margins used. Conclusions: Our 5-years’ experience showed a very high LC rate. The strategy we used for CTV delineation was safe and reliable. Determined CTV through GTV expansion to a minimally required margin, using GTV + margin (used in our T4 patients) + the whole nasopharyngeal mucosa, especially for the patients with early T disease, might be feasible

    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.

  14. Treating dose of target volume of nasopharyngeal carcinoma and contiguous organ at risk influenced by MRI and CT image difference in cranial base

    International Nuclear Information System (INIS)

    Objective: To study the treating dose of target volume of nasopharyngeal carcinoma (NPC) and contiguous organ at risk influenced by magnetic resonance imaging (MRI) and computed tomography (CT) Image difference in cranial base. Methods: 26 cases were performed from 101 patients of NPC with MRI and CT image difference in cranial base. We applied ARTP-TOP3D-TPS system to delineate target volume of NPC and contiguous organ at risk and develop the three-dimensional conformal radiotherapy (3-DCRT) plan, and compared the target volume of NPC by MRI (GTVMR) with the target volume of NPC by CT (GTVCT). Results: There was statistic difference between GTVMR (47.0±16.3) cm3 and GTVCT (31.6±10.0) cm3 (Z=4.462, P5 mean dose of brainstem, spinal cord, pituitary, temporal lobe and both eyes in MRI based plan were larger. There was no statistic difference in the mean dose of spinal cord between two plans. Conclusions: The dose of target volume in 3D-CRT plan based GTVMR is superior to GTVCT, but the dose of contiguous organ at risk in 3D-CRT plan based GTVMR is higher. (authors)

  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)

  16. 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.

  17. Volumetric assessment of tumour response using functional MR imaging in patients with hepatocellular carcinoma treated with a combination of doxorubicin-eluting beads and sorafenib

    International Nuclear Information System (INIS)

    To prospectively assess treatment response using volumetric functional magnetic resonance imaging (MRI) metrics in patients with hepatocellular carcinoma (HCC) treated with the combination of doxorubicin-eluting bead-transarterial chemoembolization (DEB TACE) and sorafenib. A single center study enrolled 41 patients treated with systemic sorafenib, 400 mg twice a day, combined with DEB TACE. All patients had a pre-treatment and 3-4 week post-treatment MRI. Anatomic response criteria (RECIST, mRECIST and EASL) and volumetric functional response (ADC, enhancement) were assessed. Statistical analyses included paired Student's t-test, Kaplan-Meier curves, Cohen's Kappa, and multivariate cox proportional hazard model. Median tumour size by RECIST remained unchanged post-treatment (8.3 ± 4.1 cm vs. 8.1 ± 4.3 cm, p = 0.44). There was no significant survival difference for early response by RECIST (p = 0.93). EASL and mRECIST could not be analyzed in 12 patients. Volumetric ADC increased significantly (1.32 x 10-3 mm2/sec to 1.60 x 10-3 mm2/sec, p < 0.001), and volumetric enhancement decreased significantly in HAP (38.2 % to 17.6 %, p < 0.001) and PVP (76.6 % to 41.2 %, p < 0.005). Patients who demonstrated ≥ 65 % decrease PVP enhancement had significantly improved overall survival compared to non-responders (p < 0.005). Volumetric PVP enhancement was demonstrated to be significantly correlated with survival in the combination of DEB TACE and sorafenib for patients with HCC, enabling precise stratification of responders and non-responders.

  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

    Use of angiotensin system inhibitors (ASIs; angiotensin receptor blockers or angiotensin-converting enzyme inhibitors) has been reported to be associated with improved survival in metastatic renal cell carcinoma (mRCC), particularly when used with vascular endothelial growth factor-targeted therapies. This study was a secondary pooled analysis of two Phase III randomized controlled trials (RCTs) of patients with mRCC: NCT00334282 comparing pazopanib to placebo and NCT00720941 comparing pazopanib to sunitinib. ASI users were defined as patients using an ASI at baseline. Association with overall survival (OS; primary outcome) and progression-free survival (PFS) was evaluated using Cox proportional hazards regression. The association was adjusted in multivariable analysis for baseline systolic blood pressure (SBP), use of other antihypertensive drugs and prognostic factors comprising the Heng risk criteria for mRCC. Of 1,545 patients pooled from the two RCTs, 649 (42%) were using one or more antihypertensive drugs at baseline, 385 (59%) of which were using an ASI. In the multivariable analysis of patients using pazopanib or sunitinib, no significant association was observed between baseline ASI use and OS (hazard ratio [HR] 0.97 [95% confidence interval (CI) 0.80-1.18], p = 0.80) or PFS (HR 0.88 [95% CI 0.73-1.06], p = 0.17). Exploratory subgroup analysis of NCT00720941 highlighted that the effect of baseline ASI use on OS may differ between patients treated with sunitinib and pazopanib. In conclusion, use of ASIs at baseline was not a significant independent prognostic factor for improved survival in a pooled analysis of mRCC patients treated with pazopanib or sunitinib.

    Full Text Available Abstract Background We wished to evaluate the clinical response following ATP-Tumor Chemosensitivity Assay (ATP-TCA directed salvage chemotherapy in a series of UK patients with advanced ovarian cancer. The results are compared with that of a similar assay used in a different country in terms of evaluability and clinical endpoints. Methods From November 1998 to November 2001, 46 patients with pre-treated, advanced ovarian cancer were given a total of 56 courses of chemotherapy based on in-vitro ATP-TCA responses obtained from fresh tumor samples or ascites. Forty-four patients were evaluable for results. Of these, 18 patients had clinically platinum resistant disease (relapse Results The overall response rate was 59% (33/56 per course of chemotherapy, including 12 complete responses, 21 partial responses, 6 with stable disease, and 15 with progressive disease. Two patients were not evaluable for response having received just one cycle of chemotherapy: if these were excluded the response rate is 61%. Fifteen patients are still alive. Median progression free survival (PFS was 6.6 months per course of chemotherapy; median overall survival (OAS for each patient following the start of TCA-directed therapy was 10.4 months (95% confidence interval 7.9–12.8 months. Conclusion The results show similar response rates to previous studies using ATP-TCA directed therapy in recurrent ovarian cancer. The assay shows high evaluability and this study adds weight to the reproducibility of results from different centres.

  2. Assessment of contralateral neck failure in 229 cases of carcinoma of the tonsillar region treated with techniques designed to spare contralateral parotid function

    International Nuclear Information System (INIS)

    Purpose/Objective: Radiation-induced xerostomia is a frequent cause of morbidity in head and neck cancer patients. To minimize this complication unilateral techniques (UT) designed to treat the primary tumor and ipsilateral neck have been used for many years in selected cases at our institution. Although such techniques exclude the contralateral parotid from the high dose target volume, they also leave the contralateral neck nodes untreated. The purpose of the study was to evaluate the risk of failure in the opposite neck. Materials and Methods: We identified 229 patients treated with UT from a series of 641 cases with carcinoma of the tonsillar region treated with curative intent between 1970 and 1991. Detailed documentation of the tumor, the radiation dosimetry, the sites of failure, and outcome including local, regional, and distant failure, and late complications, were performed. Actuarial 5-year plots were used to calculate local control, regional control, and survival rates. Results: Median age was 61 years (74 females/155 males); median follow-up 8 years (range 6 months to 21 years). AJCC (1992) T categories were T1:73, T2:120, T3:30, T4:6. The N category distribution was: N0:136, N1:53, N2a:29, N2b:8, and N3:8 cases. Base of tongue and palate were involved in 49 and 82 cases respectively. Irradiation techniques consisted of ipsilateral wedge pairs with Cobalt of 6MV photons in 210 cases (92%), while the remainder were electrons with or without photons. Customized compensators were used in the majority of cases in addition to the use of wedge filters. 75% received 50 Gy in 4 weeks, 10% received 60 Gy in 6 weeks, while the remainder received other doses intended to be curative. A radioactive implant was also used in 20 patients. The 5-year actuarial rates were as follows: overall local control: 76%, regional node control: 80%; cause specific survival: 80%. A total of 7 patients manifested regional disease in the opposite neck (crude rate of 3% or 7 of 229

  3. Re: Confocal Laser Endomicroscopy in the Management of Endoscopically Treated Upper Urinary Tract Transitional Cell Carcinoma: Preliminary Data

    2016-03-01

    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

  4. Evaluation of effect of body mass index and weight loss on survival of patients with nasopharyngeal carcinoma treated with intensity-modulated radiation therapy

    International Nuclear Information System (INIS)

    Previous studies report body-mass index (BMI) and percent weight loss (WL) to have prognostic significance when treating patients with nasopharyngeal carcinoma (NPC). However, most of these investigations studied patients treated using different radiotherapeutic techniques. We evaluated the predictive effect of these two nutrition-related measurements on therapeutic outcome in NPC patients who only received intensity-modulated radiation therapy (IMRT) as part of their total treatment program. We retrospectively studied NPC patients treated with IMRT from January 2006 to February 2012. Cox proportional hazards was used to test the association of pretreatment BMI (<23 kg/m2 vs. ≥23 kg/m2) and percent weight loss (≥5 % vs. <5 %) during therapy and related survival rates while controlling for various potential confounders. Eighty-one (34 %) of the 238 patients had BMIs ≥23 kg/m2 at pretreatment and 150 (63 %) had significant (≥5 %) weight loss. Median follow-up time was 41.71 months; median radiotherapy was 7.46 ± 0.77 weeks. Those with BMIs ≥23 kg/m2 did not have a better 3-year overall survival (p = 0.672), 3-year disease specific survival (p = 0.341), 3-year locoregional free survival (p = 0.281), or 3-year distant metastatic free survival (p = 0.134). Those with significant WL (≥5 %) did not have worse 3-year clinical endpoints, even after stratifying magnitude of weight loss by BMI category. In sensitivity test, the adjusted hazard ratio remained statistically insignificant using different cutoffs for BMIs and percent weight loss. This study found no significant relationship between BMI and percent weight loss on survival of NPC patients receiving IMRT based therapy. Further studies might want to consider other nutrition related factors as prognostic indicators when studying the correlate between malnutrition and survival in this population.

  6. Carcinoma of the intact uterine cervix treated with radiotherapy alone: a French cooperative study: update and multivariate analysis of prognostics factors

    International Nuclear Information System (INIS)

    Purpose: To determine independent prognostic factors in a group of 1875 patients with invasive carcinoma of the intact uterine cervix treated with radiotherapy alone in a French cooperative study from 1970 to 1993. Materials and Methods: Patients were staged according to the UICC-FIGO and MDAH sub staging. The distribution per FIGO stage was Ia-Ib: 25.5%; IIa: 12%; IIb: 29%; IIIa: 5%; IIIb: 25%, and IV: 3.5%. Ninety-two percent had squamous cell carcinoma. The maximum diameter of the clinically detectable cervical disease was less than 3 cm in 24.5% of Stages I-II and in 10% of Stages III-IV, more than 5 cm in 13.5% of Stages I-II, and in 16% of Stages III-IV. Nodal involvement was shown on lymphangiogram in 16% of Stages I-II and in 32.5% of Stages III-IV. Results: 1) Univariate analysis of Stages I and II: stage, cervical disease diameter, and nodal involvement are significant prognostic factors. Five-year specific survival rate (5ySS) is 83.5% in Stage Ib, 81% in IIa and 71% in IIb. Five-year disease-free survival rate (5yDFS) is 86% in tumors less of 3 cm, 76% in tumors of 3 to 5 cm, and 61.5% in tumor larger than 5 cm. Lymph angiogram strongly influences the 5-year pelvic disease-free survival rate (5yPDFS): respectively, 90% in non positive lymph angiogram vs. 65% when positive. A significant drop in specific and disease-free survival is observed (10 and 14%, respectively (p = 0.04) when comparing adenocarcinoma and squamous cell carcinoma. Age is a significant prognostic factor for specific survival because patients aged less than 30 years old have 91% vs. about 75% for patients over 30 years (p = 0.03). 2) Univariate analysis of Stages III-IV: Stage and positive lymph angiogram are predictive factors for relapse and death. The MDAH sub staging is more reliable to predict the probability of pelvic disease-free survival in Stage III. At 5 years, the FIGO Stages IIIa and IIIb have a rather similar PDFS (65% vs. 59%). Conversely, the difference of survival

  8. Correlation of clinical and pathologic features with outcome in patients with ductal carcinoma in situ of the breast treated with breast-conserving surgery and radiotherapy

    International Nuclear Information System (INIS)

    Purpose: Although breast-conserving surgery followed by radiotherapy (RT) has become a standard treatment option for patients with ductal carcinoma in situ of the breast, risk factors for ipsilateral breast tumor recurrence (IBTR) in these patients remain an active area of investigation. The purpose of this study was to evaluate the impact of clinical and pathologic features on long-term outcome in a cohort of DCIS patients treated with breast-conserving surgery plus RT. Methods and Materials: Between 1973 and 1998, 230 patients with DCIS were treated with breast-conserving surgery plus RT at our institution. All patients were treated by local excision followed by RT to the breast to a total median tumor bed dose of 64 Gy. Adjuvant hormonal therapy was used in only 20 patients (9%). All available clinical, pathologic, and outcome data, including ipsilateral and contralateral events, were entered into a computerized database. The clinical and pathologic variables evaluated included detection method, mammographic appearance, age, family history, histologic subtype, presence of necrosis, nuclear grade, final margin status, and use of adjuvant hormonal therapy. Results: As of December 15, 2000, with a median follow-up of 8.2 years, 17 patients had developed a recurrence in the ipsilateral breast, resulting in a 5- and 10-year IBTR rate of 5% and 13%, respectively. Contralateral breast cancer developed in 8 patients, resulting in a 10-year contralateral recurrence rate of 5%. Patient age, family history, histologic subtype, margin status, and tumor grade were not significantly associated with recurrence on univariate analysis. A significantly higher rate of local relapse was observed in patients with the presence of necrosis. The 10-year relapse rate was 22% in 88 patients with necrosis compared with 7% in 142 patients without necrosis (p <0.01). In multivariate analysis, the presence of necrosis remained a significant predictor of local relapse. No breast relapses

  9. The Role of Diffusion-Weighted Magnetic Resonance Imaging in the Treatment Response Evaluation of Hepatocellular Carcinoma Patients Treated With Radiation Therapy

    International Nuclear Information System (INIS)

    Purpose: We investigated the role of diffusion-weighted magnetic resonance imaging (DW MRI) as a response evaluation indicator for hepatocellular carcinoma (HCC) treated with radiation therapy (RT). Methods and Materials: Inclusion criteria of this retrospective study were DW MRI acquisition within 1 month before and 3 to 5 months after RT. In total, 48 patients were enrolled. Two radiation oncologists measured the apparent diffusion coefficient (ADC). Possible predictive factors, including alteration of the ADC value before and 3 to 5 month after RT, in relation to local progression-free survival (LPFS) were analyzed and compared. Results: Three months after RT, 6 patients (12.5%) showed a complete response, and 27 patients (56.3%) showed a partial response when evaluated using the modified response evaluation criteria in solid tumors (mRECIST). The average ADC ± SD values were 1.21 ± 0.27 ( × 10−3 mm2/s) before and 1.41 ± 0.36 ( × 10−3 mm2/s) after RT (P<.001). The most significant prognostic factor related to LPFS was mRECIST (P<.001). The increment of ADC value (≥20%) was also a significant factor (P=.02), but RECIST (version 1.1; P=.11) was not. When RECIST was combined with the increment of ADC value (≥20%), the LPFS rates were significantly different between the groups (P=.004), and the area under the curve value (0.745) was comparable with that of mRECIST (0.765). Conclusions: ADC value change before and after RT in HCC was closely related to LPFS. ADC value and RECIST may substitute for mRECIST in patients who cannot receive contrast agents

  10. FAZA PET/CT hypoxia imaging in patients with squamous cell carcinoma of the head and neck treated with radiotherapy: Results from the DAHANCA 24 trial

    International Nuclear Information System (INIS)

    Purpose: Hypoxia is a cause of resistance to radiotherapy, especially in patients with head and neck squamous cell carcinoma (HNSCC). The purpose of this study was to evaluate 18F-fluoroazomycin arabinoside (FAZA) positron emission tomography (PET)/computed tomography (CT) hypoxia imaging as a prognostic factor in HNSCC patients receiving radiotherapy. Material and methods: Forty patients with HNSCC treated with radiotherapy (66–76 Gy) were included. Static FAZA PET/CT imaging 2 h post injection was conducted prior to irradiation. The hypoxic volume (HV) was delineated using a tumor-to-muscle value ⩾1.4. In 13 patients, a repetitive FAZA PET/CT scan was conducted during the radiotherapy treatment. Results: A hypoxic volume could be identified in 25 (63%) of the 40 tumors. FAZA PET HV varied considerably with a range from 0.0 to 30.9 (median: 0.3) cm3. The Tmax/Mmed ranged from 1.1 to 2.9 (median: 1.5). The distribution of hypoxia among the Human Papillomavirus (HPV) positive (12/16) and negative (13/24) tumors was not significant different. In the FAZA PET/CT scans performed during radiotherapy, hypoxia could be detected in six of the 13 patients. For these six patients the location of HV remained stable in location during radiotherapy treatment, though the size of the HV decreased. In 30 patients a positive correlation was detected between maximum FAZA uptake in the primary tumor and the lymph node. During a median follow up of 19 months a significant difference in disease free survival rate with 93% for patients with non hypoxic tumors and 60% for patients with hypoxic tumors could be detected. Conclusion: This study emphasizes the role of FAZA PET/CT imaging as a suitable assay with prognostic potential for detection of hypoxia in HNSCC.

    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

  12. Effect of smoking on oxygen delivery and outcome in patients treated with radiotherapy for head and neck squamous cell carcinoma – A prospective study

    International Nuclear Information System (INIS)

    Background: Head and neck cancer patients with high hemoglobin respond better to irradiation compared to patients with low hemoglobin possibly due to hypoxia induced radioresistance. The hemoglobin level is, however, a crude indicator of the amount of oxygen available to the tissue and may be influenced by a number of factors, smoking being of potential importance. The aim of the present study was to examine the effect of smoking on available oxygen to tumors and the effect on outcome in head and neck cancer patients treated with radiotherapy in a prospective study. Materials and methods: A total of 232 consecutive patients with squamous cell carcinoma of the larynx, pharynx and oral cavity completed questionnaires on smoking habits prior to treatment. Venous blood samples were collected before and/or during treatment to determine the hemoglobin and carboxyhemoglobin level. Patients were treated with primary curative radiotherapy 62–68 Gy, 2 Gy/fx, 5 fx/week. Results: All but 12 patients had a history of smoking, 35 were long term quitters, 23 recent quitters, 54 moderate smokers and 108 heavy smokers (>1 pack/day). There was no relationship between total hemoglobin and carboxyhemoglobin, but effective hemoglobin and carboxyhemoglobin were linearly correlated. The amount of carboxyhemoglobin increased with increasing smoking status. Actuarial 5-year univariate analysis showed that heavy smokers had a significantly reduced probability of loco-regional control (44% vs. 65%, p = 0.001), disease-specific (56% vs. 77%, p = 0.003) and overall survival (39% vs. 66%, p = 0.0004) compared to non-smoking patients. Multivariate analyses showed that patients characterized as non-smokers, with low T and N classifications and high hemoglobin level had the best outcome measurements. A rise in carboxyhemoglobin significantly decreased the probability of loco-regional control and each additional pack year increased the risk of death. Smokers and former smokers develop secondary

    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

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. On univariate analysis, patients with better KPS ( P =0.03, treated with narrow applicators (6 mm vs. 10 mm, P =0.00, received CT ( P =0.00 or assigned to Gp E+I+C ( P =0.00 were more likely to develop strictures, with a trend for development of ulcers in Gp.

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.

  15. Usefulness of Positron Emission Tomography With Fluorine-18-Fluorodeoxyglucose in Predicting Treatment Response in Unresectable Hepatocellular Carcinoma Patients Treated With External Beam Radiotherapy

    International Nuclear Information System (INIS)

    Purpose: To assess the significance of the ratio between standardized uptake values (SUV) of tumor and normal liver tissue obtained from positron emission tomography with fluorine-18-fluorodeoxyglucose (FDG-PET) in predicting the response of hepatocellular carcinoma (HCC) patients treated with external beam radiotherapy (EBRT). Methods and Materials: We retrospectively analyzed 35 HCC patients who were treated with EBRT between January 2004 and June 2007. All patients underwent FDG-PET in which SUV values were obtained from tumor and normal liver tissues and were used to calculate the ratios (SUVTumor/SUVLiver). After FDG-PET, patients received liver treatment including concurrent chemoradiation, transarterial chemoembolization plus RT, or intraarterial chemotherapy plus RT. Using three-dimensional conformal RT, median dose of 45 Gy was delivered in conventional fractions. Patients underwent abdominal/pelvic CT 1 month after RT, and treatment responses were evaluated according to the Response Evaluation Criteria in Solid Tumors criteria. Results: Patients were divided into high-SUV ratio group (n = 20) and low-SUV ratio group (n = 15) according to SUV ratio at a cutoff value of 2.5. Objective responses consisting of either complete response (CR) or partial response (PR) were observed in 16 and 6 patients (46% vs. 17%, p = 0.015), respectively; median survivals after RT were 8 months and 5 months (p = 0.41) for the high-SUV ratio group and the low-SUV ratio group, respectively. Rates of intrahepatic metastases (9% vs. 11%, p = 0.39) and distant metastases (32% vs. 32%, p = 0.27) showed no significant difference between two groups. Conclusions: External beam RT for HCC patients with higher SUV ratios resulted in higher response rates than for patients with lower SUV ratios. Treatment of HCC with higher SUV ratios did not result in increased survival; high rates of intrahepatic and distant metastases in both SUV groups may have affected patient survival. SUV ratios

    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

  20. 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

    Objectives: To investigate the volumetric iodine-uptake (VIU) changes by dual-energy CT (DECT) in assessing the response to sorafenib treated hepatocellular carcinoma (HCC) patients, compared with AASLD (American Association for the Study of Liver Diseases) and Choi criteria. Materials and methods: Fifteen patients with HCC receiving sorafenib, monitored with contrast-enhanced DECT scans at baseline and a minimum of one follow-up (8–12 weeks) were retrospectively evaluated. 30 target lesions in total were analyzed for tumor response according to VIU and adapted Choi criteria and compared with the standard AASLD. Results: According to AASLD criteria, 67% target lesions showed disease control: partial response (PR) in 3% and stable disease (SD) in 63%. 33% lesions progressed (PD). Disease control rate presented by VIU (60%) was similar to AASLD (67%) and Choi (63%) (P > 0.05). For disease control group, change in mean VIU was from 149.5 ± 338.3 mg to 108.5 ± 284.1 mg (decreased 19.1 ± 42.9%); and for progressive disease group, change in mean VIU was from 163.7 ± 346.7 mg to 263.9 ± 537.2 mg (increased 230.5 ± 253.1%). Compared to AASLD (PR, 3%), VIU and Choi presented more PR (33% and 30%, respectively) in disease control group (P < 0.05). VIU has moderate consistency with both AASLD (kappa = 0.714; P < 0.005) and Choi (kappa = 0.648; P < 0.005), while VIU showed a better consistency and correlation with AASLD (kappa = 0.714; P < 0.005; r = 0.666, P < 0.005) than Choi with AASLD (kappa = 0.634, P < 0.005; r = 0.102, P = 0.296). Conclusion: VIU measurements by DECT can evaluate the disease control consistent with the current standard AASLD. Measurements are semi-automatic and therefore easy and robust to apply. As VIU reflects vital tumor burden in HCC, it is likely to be an optimal tumor response biomarker in HCC.

    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

Compared to AASLD (PR, 3%), VIU and Choi presented more PR (33% and 30%, respectively) in disease control group (P < 0.05). VIU has moderate consistency with both AASLD (kappa = 0.714; P < 0.005) and Choi (kappa = 0.648; P < 0.005), while VIU showed a better consistency and correlation with AASLD (kappa = 0.714; P < 0.005; r = 0.666, P < 0.005) than Choi with AASLD (kappa = 0.634, P < 0.005; r = 0.102, P = 0.296). Conclusion: VIU measurements by DECT can evaluate the disease control consistent with the current standard AASLD. Measurements are semi-automatic and therefore easy and robust to apply. As VIU reflects vital tumor burden in HCC, it is likely to be an optimal tumor response biomarker in HCC

  4. Mammographically detected ductal carcinoma in situ of the breast treated with breast-conserving surgery and definitive breast irradiation: long-term outcome and prognostic significance of patient age and margin status

    International Nuclear Information System (INIS)

    Purpose: This study was performed to determine the long-term outcome for women with mammographically detected ductal carcinoma in situ (DCIS; intraductal carcinoma) of the breast treated with breast-conserving surgery followed by definitive breast irradiation. Methods and Materials: An analysis was performed of 422 mammographically detected intraductal breast carcinomas in 418 women from 11 institutions in North America and Europe. All patients were treated with breast-conserving surgery followed by definitive breast irradiation. The median follow-up time was 9.4 years (mean, 9.4 years; range, 0.1-19.8 years). Results: The 15-year overall survival rate was 92%, and the 15-year cause-specific survival rate was 98%. The 15-year rate of freedom from distant metastases was 94%. There were 48 local failures in the treated breast, and the 15-year rate of any local failure was 16%. The median time to local failure was 5.0 years (mean, 5.7 years; range, 1.0-15.2 years). Patient age at the time of treatment and final pathology margin status from the primary tumor excision were both significantly associated with local failure. The 10-year rate of local failure was 31% for patient age ≤ 39 years, 13% for age 40-49 years, 8% for age 50-59 years, and 6% for age ≥ 60 years (p=0.0001). The 10-year rate of local failure was 24% when the margins of resection were positive, 9% when the margins of resection were negative, 7% when the margins of resection were close, and 12% when the margins of resection were unknown (p=0.030). Patient age ≤ 39 years and positive margins of resection were both independently associated with an increased risk of local failure (p=0.0006 and p=0.023, respectively) in the multivariable Cox regression model. Conclusions: The 15-year results from the present study demonstrated high rates of overall survival, cause-specific survival, and freedom from distant metastases following the treatment of mammographically detected ductal carcinoma in situ of the

  5. Hepatocellular Carcinoma Metastasis to the Orbit in a Coinfected HIV+ HBV+ Patient Previously Treated with Orthotopic Liver Transplantation: A Case Report

    2011-01-01

    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.

  6. 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

  7. Primary subglottic carcinoma

    International Nuclear Information System (INIS)

    Primary subglottic carcinoma is rare with a uniformly poor prognosis. We present our experience of eight such cases treated over a period of ten years. One patient had a mucoepidermoid carcinoma while the rest has a squamous cell carcinoma. A combination of surgery and radiotherapy was employed in five cases, while one case underwent radiotherapy only, surgery only and salvage surgery following radical irradiation. Three cases died of locoregional failure within a year. The remaining five patients have been disease-free for six months to 3.5 years. (author). 15 refs., 1 tab

    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.

  19. 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.

  20. Impact of the prophylactic gastrostomy for unresectable squamous cell head and neck carcinomas treated with radio-chemotherapy on quality of life: Prospective randomized trial

    International Nuclear Information System (INIS)

    Background and purpose: Concomitant radio-chemotherapy is the gold standard treatment for unresectable head and neck carcinomas. Placement of prophylactic gastrostomy has been proposed to provide adequate nutrition during the therapeutic sequence. The objectives of this study were to assess the impact of prophylactic gastrostomy on the 6-month quality of life, and to determine the factors related to this quality of life. 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.

  1. 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)

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

    International Nuclear Information System (INIS)

    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 (p>0.10). 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. (orig.)

  5. The influence of positive margins and nerve invasion in adenoid cystic carcinoma of the head and neck treated with surgery and radiation

    International Nuclear Information System (INIS)

    Purpose: Surgery is the primary treatment for adenoid cystic carcinomas arising from major and minor salivary glands of the head and neck. However, local recurrence is frequent because of the infiltrative growth pattern and perineural spread associated with these tumors. At UTMDACC, we have had a long-standing policy of using postoperative radiotherapy to reduce the risk of local recurrence and to avoid the need for radical surgery; this 30-year retrospective study analyzes the results of this combined modality approach. Methods and Materials: Between 1962 and 1991, 198 patients ages 13-82 years, with adenoid cystic carcinomas of the head and neck, received postoperative radiotherapy for known or suspected microscopic residual disease following surgery. Distribution of primary sites was: parotid: 30 patients; submandibular/sublingual: 41 patients; lacrimal: 5 patients; and minor salivary glands: 122 patients. Eighty-three patients (42%) had microscopic positive margins and an additional 55 (28%) had close (≤5 mm) or uncertain margins. One hundred thirty-six patients (69%) had perineural spread with invasion of a major (named) nerve in 55 patients (28%). Using radiation techniques appropriate to the primary site, a median dose of 60 Gy (range 50-69 Gy) was delivered to the tumor bed. Follow-up ranged from 5-341 months (median, 93 months). All surviving patients had a minimum of 2 years follow-up. Results: Twenty-three patients (12%) had local recurrences with 5-, 10-, and 15-year actuarial local control rates of 95%, 86%, and 79%, respectively. Fifteen of the 83 patients (18%) with positive margins developed local recurrences, compared to 5 of 55 patients (9%) with close or uncertain margins, and 3 of 60 patients (5%) with negative margins (p 0.02). Patients with and without a major (named) nerve involved had crude failure rates of 18% (10 out of 55) and 9% (13 out of 143), respectively (p 0.02). There was a trend toward better local control with increasing dose

    Background Axitinib, a selective and potent tyrosine kinase inhibitor of vascular endothelial growth factor receptors, was available to patients from Canada and Australia, prior to regulatory approval of axitinib in these countries, for treatment of clear-cell metastatic renal cell carcinoma (mRCC) after failure of one prior systemic regimen. Methods This single-arm, open-label study of axitinib evaluated the efficacy, safety, and quality of life (QoL) in patients with mRCC whose disease progressed after one prior systemic first-line regimen. Primary objective was objective response rate evaluated per Response Evaluation Criteria in Solid Tumors (RECIST) and Choi criteria. Progression-free survival, overall survival, safety, and QoL were secondary end points. Due to the small study size, analyses comprised of descriptive statistics. Results Fifteen patients were recruited, five from Canada and ten from Australia, over a limited recruitment period. Thirteen patients received sunitinib as prior therapy. All patients had clear-cell carcinoma, eleven had prior nephrectomy. Liver, lung, and lymph nodes were the most frequent sites of metastases; one patient had brain metastasis. Median time on axitinib was 118.0 days (range: 3.5–645.0 days); estimated survival probability at 12 months was 57.8%. Two (13.3%) patients had objective responses per RECIST versus nine (60.0%) per Choi criteria. Six patients had progressive disease based on RECIST versus three per Choi criteria. Nine (60.0%) events of progression or death occurred by the end of study, and three patients continued to receive the study drug. Fatigue (33%) and diarrhea (20%) were the most common grade ≥3 all-causality, treatment-emergent adverse events. The mean change in European Quality of Life – 5 Dimensions score from baseline to end of treatment was −0.0837. Conclusion The small number of patients and lack of a comparator arm limit the ability to draw definitive conclusions; however, safety and

    Although rare, severe hidradenitis suppurativa (HS) of the anal, perianal, gluteal, thigh, and groin regions can evolve into squamous cell carcinoma (SCC). This usually does not occur until the HS has been present for more than 20 years. Malignant degeneration of HS in the axilla has not been reported. SCC has developed in dissecting cellulitis, acne conglobata, and pilonidal cysts (other members of the follicular tetrad). Whereas the male to female ratio of HS is 1:3, SCC in HS has a male to female ration of 5:1. The reasons behind malignant degeneration in HS are complex and might differ from the malignant degeneration causing Marjolin ulcers. It likely involves the presence of human papilloma virus (HPV) in affected areas (a rarity in the axilla), and impaired defensins, which combat HPV, in the skin of Hurley Stage III HS. In familial HS, the odds of developing SCC are likely greater because of independent loss-of-function mutations in the γ-secretase multiprotein complex, which regulates the Notch signaling pathway. Compromise of the Notch signaling pathway can undermine immune function and increase the risk of neoplastic development. Coincident SCC with use of tumor necrosis factor α blockers has been reported. I report a patient with long standing Hurley Stage III, familial HS, wwho developed metastatic SCC after 3 courses of infliximab and expired 11 months after the infliximab was started. A 47-year-old male presented with progressive HS since early adulthood. His stage III hidradenitis suppurativa (HS) involved his groin, legs buttocks, and perineal areas.

    Octreotide may extend survival in hepatocellular carcinoma (HCC). Forty-one per cent of HCCs have high-affinity somatostatin receptors. We aimed to determine the feasibility, safety, and activity of long-acting octreotide in advanced HCC; to identify the best method for assessing somatostatin receptor expression; to relate receptor expression to clinical outcomes; and to evaluate toxicity. Sixty-three patients with advanced HCC received intramuscular long-acting octreotide 20 mg monthly until progression or toxicity. Median age was 67 years (range 28-81 years), male 81%, Child-Pugh A 83%, and B 17%. The aetiologies of chronic liver disease were alcohol (22%), viral hepatitis (44%), and haemochromatosis (6%). Prior treatments for HCC included surgery (8%), chemotherapy (2%), local ablation (11%), and chemoembolisation (6%). One patient had an objective partial tumour response (2%, 95% CI 0-9%). Serum alpha-fetoprotein levels decreased more than 50% in four (6%). Median survival was 8 months. Thirty four of 61 patients (56%) had receptor expression detected by scintigraphy; no clear relationship with clinical outcomes was identified. There were few grade 3 or 4 toxicities: hyperglycaemia (8%), hypoglycaemia (2%), diarrhoea (5%), and anorexia (2%). Patients reported improvements in some symptoms, but no major changes in quality of life were detected. Long-acting octreotide is safe in advanced HCC. We found little evidence of anticancer activity. A definitive randomised trial would identify whether patients benefit from this treatment in other ways. PMID:16953241

    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.

    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.

  11. 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.

    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

  15. Prognostic value of α-fetoprotein and des-γ-carboxy prothrombin responses in patients with hepatocellular carcinoma treated with transarterial chemoembolization

    International Nuclear Information System (INIS)

    Alpha-fetoprotein (AFP) and des-gamma-carboxy prothrombin (DCP) have been used as diagnostic tools for hepatocellular carcinoma (HCC). However, prediction of outcome using AFP and DCP has not been elucidated. We investigated the clinical role of AFP and DCP as predictors of treatment outcome in patients with HCC undergoing trans-arterial chemoembolization (TACE). Between January 2003 and December 2005, we enrolled 115 treatment-naïve patients who received TACE as an initial treatment modality. An AFP or DCP response was defined as a reduction of more than 50% from the baseline level 1 month after TACE. Patients with AFP < 20 ng/mL or DCP < 20 mAU/mL were excluded. The median age was 59 years and the male gender predominated (n = 81, 70.4%). AFP and DCP response was identified in 91 (79.1%) and 77 (66.9%) patients after TACE. Although progression-free survival (PFS) did not differ according to AFP response (P = 0.150), AFP responders showed significantly better overall survival (OS) than non-responders (34.9 vs. 13.2 months; P = 0.002). In contrast, DCP response did not influence either PFS or OS (all P > 0.05). Multivariate analyses showed that gamma-glutamyltranspeptidase and baseline AFP were predictors of PFS (all P < 0.05) and that male gender, the presence of liver cirrhosis, baseline DCP, number of measurable tumors and AFP response were independent predictors of OS (all P < 0.05). AFP response and higher baseline DCP level are significant predictors of OS in treatment-naïve patients with HCC receiving TACE who showed pretreatment elevation of both AFP and DCP

  16. Artificial neural network model of survival in patients treated with irradiation with and without concurrent chemotherapy for advanced carcinoma of the head and neck

    International Nuclear Information System (INIS)

    Purpose: This study was performed to investigate the feasibility of predicting survival in squamous cell carcinoma of the head and neck (SCCHN) with an artificial neural network (ANN), and to compare ANN performance with conventional models. Methods and Materials: Data were analyzed from a Phase III trial in which patients with locally advanced SCCHN received hyperfractionated irradiation with or without concurrent cisplatin and 5-fluorouracil. Of the 116 randomized patients, 95 who had 2-year follow-up and all required data were evaluated. ANN and logistic regression (LR) models were constructed to predict 2-year total survival using round-robin cross-validation. A modified staging model was also examined. Results: The best LR model used tumor size, nodal stage, and race to predict survival. The best ANN used nodal stage, tumor size, stage, and resectability, and hemoglobin. Treatment type did not predict 2-year survival and was not included in either model. Using the respective best feature sets, the area under the receiver operating characteristic curve (Az) for the ANN was 0.78 ± 0.05, showing more accurate overall performance than LR (Az = 0.67 ± 0.05, p = 0.07). At 70% sensitivity, the ANN was 72% specific, while LR was 54% specific (p = 0.08). At 70% specificity, the ANN was 72% sensitive, while LR was 54% sensitive (p = 0.07). When both models used the five predictive variables best for an ANN, Az for LR decreased [Az = 0.61 ± 0.06, p z = 0.60 ± 0.07, p = 0.02 (ANN)]. Conclusions: An ANN modeled 2-year survival in this data set more accurately than LR or staging models and employed predictive variables that could not be used by LR. Further work is planned to confirm these results on larger patient samples, examining longer follow-up to incorporate treatment type into the model

  17. Radiotherapeutic management of nasopharyngeal carcinoma. A critical review of 601 cases treated at the Cancer Institute in the period 1947 to 1969

    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.

    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.

  19. 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

  20. Radiation therapy for advanced laryngeal carcinoma

    International Nuclear Information System (INIS)

    From 1967 through 1985, 92 patients with T3 and T4 laryngeal carcinoma were treated with radiation at Osaka University Hospital. Of 92 patients, patients with 14 T3 and 29 T4 carcinoma were treated with a total dose of 60 Gy or more, and those with 14 T3 and 21 T4 carcinoma were treated with a total dose of 40 to 58 Gy and followed by total laryngectomy. Other 14 patients were palliatively treated with a total dose less than 60 Gy without surgery. The 5-year local control rates for T3 and T4 carcinoma treated with radical radiation were 48% and 24%, respectively. The 5-year cause-specific survival rates for T3 carcinoma treated with radical and preoperative radiotherapy were 48% and 71%, and corresponding figures for T4 carcinoma were 52% and 43%. There were no statistically significant differences between cause-specific survival rates of radical and preoperative groups. The 5-year cause-specific survival rates for T3N0 and T4N0 cases treated with radical radiation were 83% and 56%, and corresponding figures for T3N+ and T4N+ cases were 13% and 45%. Voice preservation rates of T3 and T4 patients treated with radical radiation were about 1/2 and 1/4, respectively. Considering the QOL of patients, radiotherapy for advanced carcinoma of larynx should be considered as a primary treatment especially for N0 cases. (author)

    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 highe...

  3. Early assessment by FDG-PET/CT of patients with advanced renal cell carcinoma treated with tyrosine kinase inhibitors is predictive of disease course

    International Nuclear Information System (INIS)

    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.

  5. Impact of Prophylactic Cranial Irradiation Timing on Brain Relapse Rates in Patients With Stage IIIB Non–Small-Cell Lung Carcinoma Treated With Two Different Chemoradiotherapy Regimens

    International Nuclear Information System (INIS)

    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.

  6. Superior prognostic utility of gross and metabolic tumor volume compared to standardized uptake value using PET/CT in head and neck squamous cell carcinoma patients treated with intensity-modulated radiotherapy

    International Nuclear Information System (INIS)

    The objective of this study was to compare the prognostic utility of the 2-[18F] fluoro-2-deoxy-D-glucose (FDG) maximum standardized uptake value (SUVmax), primary gross tumor volume (GTV), and FDG metabolic tumor volume (MTV) for disease control and survival in patients with head and neck squamous cell carcinoma (HNSCC) undergoing intensity-modulated radiotherapy (IMRT). Between 2007 and 2011, 41 HNSCC patients who underwent a staging positron emission tomography with computed tomography and definitive IMRT were identified. Local (LC), nodal (NC), distant (DC), and overall (OC) control, overall survival (OS), and disease-free survival (DFS) were assessed using the Kaplan-Meier product-limit method. With a median follow-up of 24.2 months (range 2.7-56.3 months) local, nodal, and distant recurrences were recorded in 10, 5, and 7 patients, respectively.

    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.

    Renal cell carcinoma is the most common renal tumor in adults. Clear cell carcinoma represents 85% of all histological subtypes. In February 2012 a 72-year-old woman came to our department due to the appearance of massive hemoptysis and pharyngodinia. Previously, this patient was diagnosed with a renal cell carcinoma treated with left nephrectomy. We observed an exophytic, grayish, and ulcerated mass in the left tonsillar lodge and decided to subject the patient to an immediate tonsillectomy....

  12. Glottic ansd supraglottic carcinoma

    International Nuclear Information System (INIS)

    From 1971 through 1982, 442 patients with laryngeal carcinoma were seen at the Leiden University Hospital. They were treated either with radiotherapy alone, sandwich therapy (pre- and postoperative radiotherapy) or by surgery followed by postoperative irradiation. Three hundred and sixty-six patients with glottic or supraglottic tumours could be analysed with respect to two different treatments, complications of treatment and some prognostic factors. Two endpoints of analysis were used: disease-free interval and survival to cfancer death. In patients with glottic or supraglottic carcinoma, the survival of patients with advanced disease, treated with radiotherapy only, was worse as compared to the survival of the same category of patients who were treated with sandwich therapy (p<0.005). In small supraglottic tumours, the survival with both therapy policies was equal. There was no influence on prognosis of histological differentiation of the tumour. It appeared that interruption of radiotherapy for more tah two days had an adverse effect on survival in patients with glottic carcinoma (p=0.0001). (author). 16 refs.; 4 figs.;

    Our knowledge of renal cell carcinoma (RCC) is rapidly expanding. For those who diagnose and treat RCC, it is important to understand the new developments. In recent years, many new renal tumors have been described and defined, and our understanding of the biology and clinical correlates of these tumors is changing. Evolving concepts in Xp11 translocation carcinoma, mucinous tubular and spindle cell carcinoma, multilocular cystic clear cell RCC, and carcinoma associated with neuroblastoma are addressed within this review. Tubulocystic carcinoma, thyroid-like follicular carcinoma of kidney, acquired cystic disease-associated RCC, and clear cell papillary RCC are also described. Finally, candidate entities, including RCC with t(6;11) translocation, hybrid oncocytoma/chromophobe RCC, hereditary leiomyomatosis and RCC syndrome, and renal angiomyoadenomatous tumor are reviewed. Knowledge of these new entities is important for diagnosis, treatment and subsequent prognosis. This review provides a targeted summary of new developments in RCC. PMID:24364021

  17. 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

  18. Team practice for laryngeal carcinoma. Glottic carcinoma

    International Nuclear Information System (INIS)

    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)

    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.

    Cryotherapy has proved to be an effective tool in the management of various dermatoses. We report 6 patients with histopathologically proven basal cell carcinoma of variable sizes treated with liquid nitrogen cryotherapy by the open spray technique. Lesions tended to heal with depigmentation and scar formation. However depigmented areas often repigmented over a period of time.

  4. Prevention of hepatocellular carcinoma.

    Kew, Michael C

    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

  5. Preliminary results of toxicity, biochemical and histological response in patients with carcinoma of the prostate treated on a prospective dose-finding study with 3-D conformal mixed neutron and photon irradiation

    International Nuclear Information System (INIS)

    Purpose: To determine the incidence of chronic toxicity and the probabilities of biochemical and histologic response among patients with carcinoma of the prostate (CaP) treated with 3D conformal mixed neutron and photon irradiation with or without neo-adjuvant hormonal therapy. Materials and Methods: Between November 1991 and December 1994, 150 patients with prostate cancer were entered on 3 prospective dose-finding studies of conformal mixed neutron and photon irradiation. The neutrons were produced from a superconducting cyclotron with a 48 MeV deuteron beam. Patients with low stage, low to intermediate grade CaP (T1-2, Nx,M0, Gleason score ≤ 7) were treated with conformal photon irradiation (38 PhGy) plus non-axial conformal neutron irradiation to 9 Neutron Gy (51 pts) or 10 N Gy (52 patients). Forty-seven patients with locally advanced CaP (T3-4, N0-N1, M0, Gleason score ≥ 8) received 15 N Gy plus 18 Ph Gy to the prostate and 9 NGy + 18 PhGy to the pelvic lymph nodes. The mean pre-treatment PSA values for the two groups were 11.3 and 46.1 ng/ml, respectively. Major prognostic factors were balanced between the 78 patients who did and the 72 who did not receive neo-adjuvant hormonal therapy. Toxicity was scored according to the RTOG toxicity scale. The median follow-up was 12 months. Results: The overall incidence of gastrointestinal (GI) toxicity at 12 months was: grade (0(I)) 92.5%, grade II = 7%, grade III = 1.5%, grade IV = 0%. The overall incidence of genitourinary (GU) toxicity at 12 months was: grade (0(I)) = 94%, grade II = 3%, grade III = 3%, grade IV = 0%. Grade II skin toxicity was recorded in 15% of patients. Stiffness in flexing or abducting the hips at doses of 9 or 10 and 15 NGy was 20% and 42% respectively (p < 0.05). Severe hip stiffness was seen in 0% and 26% of patients, respectively (p < 0.05). At 9 or 10 NGy, 2.6% of patients had grade II GI or GU complications compared with 21% grade II and III at 15 NGy (p < 0.05). Potency was retained

  6. Carcinoma of the penis

    International Nuclear Information System (INIS)

    Seventy-eight patients with carcinoma of the penis treated over a period of twelve years (1972-1983) were retrospectively analyzed. According to Jackson's clinical staging, 18.0% were in stage I, 20.5 in stage II, 26.9 in stage III, and 34.6% in stage IV. Some early-stage patients (12 with stage I and 4 with stage II) were primarily treated by external irradiation to a dose of 55 Gy/5 week/25 fr. Thirteen of these 16 patients had local control with preservation of the organ. The remaining patients with stage II were treated by partial or total penectomy. In stage III penectomy with inguiopelvic lymph node dissection was done. Stage IV patients received palliative irradiation and/or chemotherapy. There years' disease-free survival (including salvage surgery) was 93% in stage I, 62.5% in stage II and 38% in stage III. (orig.)

  7. Carcinoma multiplex

    International Nuclear Information System (INIS)

    Multiple primaries in a single patient are uncommon, though not very rare. The existence of such cancers in two un-related, non-paired organs is even more un-common. Here, we present a case of 55 years old male who presented to us with a mucoepidermoid carcinoma of the parotid gland and was operated. Later on, he presented with a large cystic swelling in the pelvis which turned out to be pseudomyxoma peritonei. A review of slides and immunohistochemistry indicated it to be adenocarcinoma colon. He presented again with recurrent mucoepidermoid carcinoma of the parotid which was operated successfully with the use of myocutaneous flap for wound closure. He is currently undergoing chemotherapy. In order to establish a separate mono-clonal etiology of both tumours, immunohistochemistry was performed. To the best of our knowledge, carcinoma multiplex in the colon and the parotid has never been reported before. (author)

  9. Radiotherapy of bile duct carcinoma

    International Nuclear Information System (INIS)

    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 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)

  10. 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

  11. Carcinomas of the nasal cavity

    International Nuclear Information System (INIS)

    Between 1969-1985, 45 patients with carcinomas of the nasal cavity proper received curative treatment. Of these, 30 had squamous cell carcinoma, 1 un-differentiated carcinoma, 9 adenocarcinoma and 5 adenoid cystic carcinoma. 18 Patients were treated with definitive radiotherapy (interstitial brachy-therapy in 5 patients and external beam therapy in 13 patients), 27 received surgery and radiotherapy. Median length of follow-up was 11 years (range 2.8-16.8 years). 36 Patients had no evidence of disease at the last follow-up visit. All 14 patients with carcinoma of nasal septum had the disease controlled. 9/31 Patients with lesions of lateral wall and floor died of the disease, 5 of uncontrolled local disease, 2 of distant metastases, 2 of both. Disease specific survival rates at 5 and 10 years were 83 and 80%, the corresponding overall survival rates were 75 and 60%. Blindness occurred in 4 patients, 2 due to orbital exenteration and 2 to radiation injury to the cornea and optic pathway. Other infrequent side effects were bone necrosis, dental decay, nasal stenosis and septal perforation. This study indicated that prognosis of patients with nasal cavity carcinoma was better than that of patients with maxillary sinus cancer treated during the same era. In addition, the study showed that carcinoma of the nasal septum were smaller than those of lateral wall and floor at diagnosis, so that excellent control could be achieved by definitive radiotherapy; when accessible, interstitial brachytherapy might be the treatment of choice in such patients.

    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)

    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.

The overall actuarial survival rate was 80% at 3 years, 77% at 5 years and 60% at 10 years. The result of irradiation treatment combined with bleomycin was in stage N0 equivalent to that of surgical therapy. The non-surgical treatment had the advantage of preserved sexual ability. (orig.)

  17. Clinical parotid carcinoma analysis

    International Nuclear Information System (INIS)

    We clinically analyzed 48 consecutive retrospective cases of parotid carcinoma initially treated between 1988 and 2007. Subjects were 30 males and 18 females ranging from 5 to 85 years old (average: 57.9 years). Of the 12 histological types seen, the most common was mucoepidermoid carcinoma, seen in 12 subjects (25.0%). We studied their survival based on 5 potential prognostic factors-stage, T stage, neck metastasis, facial nerve palsy, and malignancy grade-together with features of mortality and recurrence. Overall 5-year disease-specific survival was 71.2% and 10-year survival 54.9%. Survival rates were significantly lower in stage IV and high-grade malignancy groups than in stage I-III and low-grade malignancy groups. T stage, neck metastasis, and facial nerve palsy tended to compromise survival. Recurrence developed in 2 subjects, in whom significant recurrence risk factors were stage III-IV (particularly, stage IV), T3-4, and high-grade malignancy. Of 18 deaths, causes were distant failure in 11 and local failure in 5. None died of nodal failure. Analysis of these prognostic factors is important in selecting appropriate surgery and in determining indications for postoperative radiotherapy and chemotherapy, leading to better treatment outcome in those with parotid carcinoma.

  18. 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)

    of intensity modulated radiation therapy (IMRT) in the treatment of nasopharyngeal carcinoma (NPC) at 2008 stage. Methods A total of 60 cases of nasopha-ryngeal carcinoma patients, who was confirmed by pathological examination in our hospital from February 2014 to No-vember 2015, were divided intoⅠstage (n=4),Ⅱstage (n=12),Ⅲstage (n=25) andⅣstage (n=19) according to 2008 Guangzhou staging standards. Sixty cases received IMRT, and some patients received comprehensive treatment. Accord-ing to ICRU52 and 60, the patients underwent IMRT with modified dose fractionation patterns at the dose of 68 Gy/30~33 fraction for nasopharyngeal gross tumor volume (GTVnx), at the dose of 64~68 Gy/30~33 fraction for neck gross tumor vol-ume (GTVnd), at the dose of 60 Gy/30~33 fraction for clinical target volume 1 (CTV1), at the dose of 54 Gy/30~33 fraction for clinical target volume 2 (CTV2). All patients were treated with thermoplastic mask fixation, CT simulation, and data was send to Viran eclipse 10 IMRT plan system for target delineation, plan design and evaluation. Survival analysis was per-formed by Kaplan-Meier method, and RTOG/EORTC criteria were used to evaluate acute and late injury. Results During the median follow-up time of 9 months, the whole group had 2 patients died, with 96.7%of one-year survival rate. In 60 pa-tients, 3 cases had distant metastases, and metastatic sites were bone, liver and lung, with the rate of metastasis of 5%, of which 2 cases of local recurrence (which occurred in the twelfth months after treatment and fourteenth months) were in nasopharyngeal recurrence, and 1-year local control rate was 96.7%. Most of the patients was grade 1~2 acute reaction, and 2 patients, due to the occurrence of 3 radioactive stomatitis, did not complete the entire radiotherapy. There was no case belongs to more than 4 cases of radioactive reaction. The average dose of PGTVnx, PGTVnd, PTV1 and PTV2 were respectively 72.3 Gy, 69.3 Gy, 66.5 Gy, 58.3 Gy; The average

  5. Evolution and pathology of colorectal carcinoma

    International Nuclear Information System (INIS)

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

    Full Text Available 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.

  9. An afterloading procedure using 137Cs needle for tongue carcinoma

    International Nuclear Information System (INIS)

    We have developed an afterloading procedure using Cs needle for tongue carcinoma. Seven patients with T1-2NO squamous cell carcinoma of the oral tongue were treated by this method at the Oita Medical University between 1988 and 1994. This method reduced the radiotherapist's radiation exposure and resulted in good local control in the primary site. We have found no other report of a case treated in this way. We emphasize that cesium therapy using an afterloading procedure is very useful in treating tongue carcinoma. (author)

  12. Diagnosis and management of carcinoma of the thyroid

    International Nuclear Information System (INIS)

    Thyroid nodules are a frequent finding but engender concern primarily because of a large size or, occasionally, as a manifestation of a carcinoma. Needle biopsy permits a definite diagnosis in the majority of cases. Well-differentiated thyroid carcinoma is treated by surgery, the extent of which would be based on the gross evidence of the extent of the disease, the histologic features of the lesion, the patient's age and overall medical status, and the need to avoid postoperative complications. The appropriate care after surgery is also based on the individual patient. Medullary thyroid carcinoma is best treated by total thyroidectomy with cervical lymph node dissection on the side of a palpable nodule. Serum calcitonin determinations provide diagnostic and some prognostic data. Anaplastic carcinoma is usually best treated by radiation therapy. The outlook is good for most thyroid carcinoma recognized reasonably early

    Differentiated thyroid carcinoma was studied with regard to mode of presentation, initial findings, treatment and survival. The classic signs, symptoms, physical and scan findings were found to be present in approximately 70% of the patients. Prognosis was found to be dependent on age of presentation more than any other factor. Patients with prior exposure to radiation were found to have more extensive disease and require more extensive surgery but ultimately had the same prognosis for 15-year cure. Treatment for distant metastatic disease by surgery, radioactive iodine and external radiation all resulted in long-term survival in certain cases

  15. Radiation therapy for carcinoma of the major salivary glands

    International Nuclear Information System (INIS)

    From January 1967 through November 1991, a total of 135 patients with carcinoma of the major salivary glands (parotid: 95; submandibular: 39, sublingual: 1) were treated at our department. 40 patients had adenocarcinoma, 29 adenoid cystic carcinoma, 24 mucoepidermoid carcinoma and 16 squamous cell carcinoma. 100 patients were irradiated postoperatively and the remaining 35 were treated with radiation alone. Total radiation doses delivered were 50 Gy for the postoperative group and 50 to 66 Gy for the group receiving only radiation using a 60Co single portal with or without wedged paired or single electron portal boost. Actuarial five-year survivals after radiation therapy were 55% for the postoperative group and 26% for radiation only group (p=0.0004). The local control rates for the postoperative group were 83% for adenocarcinoma, 81% for adenoid cystic carcinoma, 83% for mucoepidermoid carcinoma and 62% for squamous cell carcinoma. Corresponding figures for the radiation only group were 40% for adenocarcinoma, 38% for adenoid cystic carcinoma and 33% for mucoepidermoid carcinoma. Conventional irradiation techniques continue to play an important role because they offer superior local control for postoperative patients with carcinoma of the major salivary glands. However, the local control rates for the radiation only group were only 30 to 40%, so that new irradiation modalities such as provided by a high LET machine are needed for these patients. (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.

    International Nuclear Information System (INIS)

    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.)

  9. Coexpression of cyclooxygenase-2 and thymidine phosphorylase as a prognostic indicator in patients with FIGO stage IIB squamous cell carcinoma of uterine cervix treated with radiotherapy and concurrent chemotherapy

    International Nuclear Information System (INIS)

    Purpose: To evaluate the prognostic significance of thymidine phosphorylase (TP) and coexpression of cyclooxygenase-2 (COX-2)/TP, and to investigate the relationship between COX-2 and TP expression in squamous cell carcinoma of the uterine cervix. Methods and Materials: Cancer specimens from 75 patients with International Federation of Gynecology and Obstetrics Stage IIB squamous cell carcinoma of the uterine cervix who had undergone radiotherapy and concurrent chemotherapy were immunohistochemically stained with COX-2 and TP antibodies and scored. The prognostic significance of their expression status, and the relationship between COX-2 and TP was investigated. Results: TP predominantly stained cytoplasm and the cell membrane of the tumor cells mainly in a diffuse and intense manner. TP was negative (50%) in 57% of patients. TP overexpression was related to a marginal prognostic significance of a poor 5-year overall survival (p = 0.082, log-rank test) and a high locoregional recurrence rate (p < 0.1, chi-square test). COX-2 and TP coexpression was observed in 24% of patients and was significantly related to poor 5-year disease-free and overall survival rates (p = 0.0083 and p 0.025, respectively), a high pelvic lymph node involvement rate, a poor response to treatment, and a greater incidence of locoregional recurrence (p < 0.05). By multivariate analyses, only COX-2, TP, and coexpression of COX-2/TP were significant independent prognostic indicators of patient survival. All tumors showed 1+ or 2+ TP expression when COX-2 was positive, and no tumor expressed COX-2 when TP was negative (p = 0.03). In contrast, 77% of tumors expressed 1+ or 2+ TP without the synchronous expression of COX-2. Conclusions: Thymidine phosphorylase expression or COX-2/TP coexpression may be used as a molecular prognostic marker for squamous cell carcinoma of the uterine cervix. TP appears to be an important downstream molecule of COX-2 during angiogenesis and may be a new target for the

  10. Radiotherapy and verrucous carcinoma of the oral cavity

    International Nuclear Information System (INIS)

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

    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.

    Full Text Available Abstract Background Bladder small cell carcinoma is an uncommon tumour. Through a retrospective study we will present the evolution of recurrent and metastatic disease and outcome of patients treated at Léon-Bérard Cancer Centre. Methods Only 15 patients having recurrent or metastatic bladder small cell carcinoma were treated at Léon-Bérard Cancer Centre between 1996 and 2007. The patients were divided in two groups: a mixed small cell carcinoma group (9 patients and a pure small cell carcinoma group (6 patients. All the records and informations related to treatment and outcome of the 15 patients were retrospectively analyzed. Various characteristics of small cell carcinoma were investigated. Results The median age of the 15 patients having recurrent or metastatic bladder small cell carcinoma and treated at Léon-Bérard Cancer Centre was 63 years and the disease was at stage IV for all cases. Nine patients were treated by chemotherapy. Four patients were treated by local radiotherapy (3 with radiotherapy without previous surgery and 1 with surgery followed by radiotherapy and chemotherapy. One patient was treated by whole brain radiotherapy. And one patient died before treatment. After 52.4 months median follow up, 12 patients died. Median overall survival was 7.6 months. Survival probability at 1 year was 33%. Median overall survival was 9.9 months in the mixed small cell carcinoma group, and was only 4.6 months in the pure small cell carcinoma group. Survival probability at 1 year in the mixed small cell carcinoma group was 44% as compared to 17% in the pure small cell carcinoma group (Log-rank test: p = 0.228. Conclusion Recurrent and metastatic bladder small cell carcinoma is associated with very poor prognosis. The pure bladder small cell carcinoma appears to have poorer outcome than the mixed bladder small cell carcinoma. Chemotherapy using platinum drugs is a mainstay treatment.

  1. 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

    Liver cancer is the second leading cause of cancer-related deaths globally and has an incidence of approximately 850,000 new cases per year. Hepatocellular carcinoma (HCC) represents approximately 90% of all cases of primary liver cancer. The main risk factors for developing HCC are well known and include hepatitis B and C virus infection, alcohol intake and ingestion of the fungal metabolite aflatoxin B1. Additional risk factors such as non-alcoholic steatohepatitis are also emerging. Advances in the understanding of the molecular pathogenesis of HCC have led to identification of critical driver mutations; however, the most prevalent of these are not yet druggable targets. The molecular classification of HCC is not established, and the Barcelona Clinic Liver Cancer staging classification is the main clinical algorithm for the stratification of patients according to prognosis and treatment allocation. Surveillance programmes enable the detection of early-stage tumours that are amenable to curative therapies - resection, liver transplantation or local ablation. At more developed stages, only chemoembolization (for intermediate HCC) and sorafenib (for advanced HCC) have shown survival benefits. There are major unmet needs in HCC management that might be addressed through the discovery of new therapies and their combinations for use in the adjuvant setting and for intermediate- and advanced-stage disease. Moreover, biomarkers for therapy stratification, patient-tailored strategies targeting driver mutations and/or activating signalling cascades, and validated measurements of quality of life are needed. Recent failures in the testing of systemic drugs for intermediate and advanced stages have indicated a need to refine trial designs and to define novel approaches. PMID:27158749

    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

    Background Prognostic factors in predicting outcomes in patients with head and neck squamous‐cell carcinoma (HNSCC) are limited to the clinical–pathological parameters, including lymph node metastasis, location, grade and stage of the disease. Aim To determine whether the expression of these proteins has a value in predicting patient outcome. Methods Ezrin, maspin and nm23‐H1 immunohistochemistry in tissue samples of 120 patients with HNSCC were evaluated using the microarray technique. Results In determining the association among each of the three proteins and the clinical–pathological parameters, low maspin expression was the only one found to be significantly associated with high tumour grade (p = 0.007); all others showed no significant associations. In univariate analysis, patients with tumours expressing high ezrin had a shorter disease‐free survival (DFS) of 51% than those with low ezrin expression (DFS 84%; p = 0.08). In multivariate analysis, tumours with the combination of loss of maspin and low histological grade had longer DFS (83%) compared with those with high maspin and high histological grade (DFS 42%; p = 0.08). Conclusion Our study is the first to determine the value of ezrin and maspin in HNSCC in a large series of patients with long follow‐up. Ezrin and maspin seem to have a potential prognostic value in patients with HNSCC but results should be confirmed with further studies. PMID:16698950

    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.

    Dracaena cinnabari Balf.f. is a red resin endemic to Socotra Island, Yemen. Although there have been several reports on its therapeutic properties, information on its cytotoxicity and anticancer effects is very limited. This study utilized a bioassay-guided fractionation approach to determine the cytotoxic and apoptosis-inducing effects of D. cinnabari on human oral squamous cell carcinoma (OSCC). The cytotoxic effects of D. cinnabari crude extract were observed in a panel of OSCC cell lines and were most pronounced in H400. Only fractions DCc and DCd were active on H400 cells; subfractions DCc15 and DCd16 exhibited the greatest cytotoxicity against H400 cells and D. cinnabari inhibited cells proliferation in a time-dependent manner. This was achieved primarily via apoptosis where externalization of phospholipid phosphatidylserine was observed using DAPI/Annexin V fluorescence double staining mechanism studied through mitochondrial membrane potential assay cytochrome c enzyme-linked immunosorbent and caspases activities revealed depolarization of mitochondrial membrane potential (MMP) and significant activation of caspases 9 and 3/7, concomitant with S phase arrest. Apoptotic proteins array suggested that MMP was regulated by Bcl-2 proteins family as results demonstrated an upregulation of Bax, Bad, and Bid as well as downregulation of Bcl-2. Hence, D. cinnabari has the potential to be developed as an anticancer agent.

    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)

    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.

    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...

    @@ 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.

    During the period 1943-67, 903 Danish patients aged less than 40 years had colorectal carcinoma. The patients were followed up for up to 41 years and during this period 44 of 501 (9 per cent) operated on for cure developed a metachronous colorectal carcinoma. The cumulative risk of a metachronous...... colorectal carcinoma was 30 per cent after up to 41 years of observation. The occurrence of a metachronous colorectal carcinoma was evenly distributed in the observation period. The cumulative survival rate after operation for a metachronous colorectal carcinoma was 41 per cent after 20 years of observation....... We propose a lifelong follow-up programme after resection of colorectal carcinoma for cure in this age group, including annual Hemoccult test and colonoscopy at 3-year intervals....

    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.

    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

    1987-11-01

    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

  7. A clinical study of oral carcinoma

    International Nuclear Information System (INIS)

    Data of a total of 62 patients with oral carcinoma treated at the University of Tsukuba Hospital between January 2001 and December 2010 were reviewed. Out of the 62 patients, in 59, the tumors were histopathologically diagnosed as squamous cell carcinoma (SCC), and the remaining three as verrucous carcinoma. Treatment for each patient was determined according to the tumor, nodes and metastasis (TNM) classification (Union for International Cancer Control (UICC), 1997) and the histopathological features. The three patients with verrucous carcinoma in whom the tumors were insensitive to radiation or chemotherapy were treated surgically. For stage I or II SCC cases, except for tongue cancer, full-dose irradiation was the treatment of choice. For cases of stage I or II tongue cancer, brachytherapy (RALS) or surgery was the treatment of choice. In stage III or IV cases, the treatment of choice was a combination of surgery, radiotherapy and chemotherapy. The 5-year survival rate of the SCC cases, overall, was 62.6% as analyzed by the Kaplan-Meier method, while the rates for the stage I, II, III, and IV cases were 100%, 75.6%, 37.5%, and 40.7%, respectively.

  8. Radiation therapy for carcinoma of the ear

    International Nuclear Information System (INIS)

    Carcinoma of the ear is rarely reported. From 1978 through 1992, we treated 9 patients, of whom 5 had malignant tumors of the external auditory canal and 4 had malignant tumors of the middle ear, with radiation. These patients accounted for only 0.9% of all patients with head and neck carcinomas treated with radiation at our hospital. Most patients had otorrhea and otalgia, but few patients had specific symptoms of carcinoma. The outcome in cases in which radiotherapy was given after tumor was completely resected was good. The overall 5-year survival rate was 55%. In addition, the 3-year survival rates in cases of carcinoma of the middle ear and of the external auditory canal were 50% and 60%. However, there was no statistical difference in 5-year survival rates between the two sites. We believe factors that affect prognosis are early diagnosis of malignant change, the area of tumor involvement at diagnosis, and combined therapy with surgery and radiation. (author)

    Purpose. - To identify prognostic factors and treatment toxicity in a series of epidermoid cancers of the anal canal without evident metastasis. Patients and methods. - Between June 1972 and January 1997, 305 patients (pts) were treated with curative-intent radiation therapy (RT). The T-stages according to the 1987 UICC classification were: 26 T1, 141 T2, 104 T3, and 34 T4. There were 49 pts with nodal involvement at presentation. Pretreatment anal function scoring according to our in-house system was: 22 scored 0, 182 scored 1, 74 scored 2, 7 scored 3. 11 scored 4, and 9 not available pts. The treatment started with external beam RT (EBRT) in 303 pts (median dose: 45 Gy). After a rest period of 4 to 6 weeks, a boost of 20 Gy was delivered by EBRT in 279 pts and by interstitial {sup 192}Ir brachytherapy (Bcy) in 17 pts. Seven pts received only one course of EBRT (mean dose: 49.5 Gy) and 2 pts were treated with interstitial {sup 192}Ir Bcy alone (55 and 60 Gy, respectively). concomitant chemotherapy (5-fluoro-uracil and either mitomycin C or cisplatin) was delivered to 19 pts. Mean follow-up was 103 months. Results. - At the end of RT local tumor clinical complete response (cCR) rate was 80%. Out of 61 non responders or local progressive tumors 27 (44%) were salvaged with abdomino-perineal resection (APR). The rate of local tumor relapse (LR) was 12%. Out of 37 LTR, 20 (54%) were salvaged with APR and one with interstitial {sup 192}Ir Bcy. The overall local tumor control (LC) rate with or without salvage local treatment was 84%. LC rate with a good anal function scoring (score 0 and 1) was 56.5%0. Among 181/186 available pts who preserved their anus, 94% had a good anal function scoring. For a subgroup of 15 pts with length tumor <2 cm-N0, the LC rate after the end of RT was 100% the LC rate with or without local salvage treatment was 100%, and among 13 available pts who preserved their anus, the anal function scoring was good in 12 pts (92%).

  10. Squamous cell carcinoma of the oral cavity

    International Nuclear Information System (INIS)

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

  11. Fast neutron therapy of bronchus carcinoma: the pooled results from two european centres

    International Nuclear Information System (INIS)

    The Berlin-Buch and Heidelberg centres used fast neutron therapy in bronchial carcinomas. The neutron source was a cyclotron in Berlin-Buch/Rossendorf and a d-t generator in Heidelberg. Three hundred twelve patients with inoperable bronchial carcinoma were treated with fast neutron therapy alone or in combination with photons. The results were then compared with those obtained from 594 patients treated only with photons. Altogether, 788 were treated in Berlin-Buch and 188 in Heidelberg. The results suggest that neutron therapy for bronchial carcinoma can be a good alternative in curative and palliative situations in the early stages. (author)

  20. Prognostic Relevance of Objective Response According to EASL Criteria and mRECIST Criteria in Hepatocellular Carcinoma Patients Treated with Loco-Regional Therapies: A Literature-Based Meta-Analysis.

    Directory of Open Access Journals (Sweden)

    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.

  1. A clinical study of oral carcinoma

    International Nuclear Information System (INIS)

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

  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

Between 1973 and 1998, 14 patients with thymic carcinoma were treated at Gunma Prefectural Cancer Center. Two patients who had hematogenous metastasis were excluded from this study, therefore 12 patients were analyzed. The Masaoka staging system was used; four patients were diagnosed with stage III disease and eight patients with stage IV disease. The pathological subtype according to the World Health Organization histological criteria for thymic tumors was squamous cell carcinoma (low-grade histology) in six cases and undifferentiated carcinoma (high-grade histology) in six. Ten patients underwent thoracotomy, and two patients underwent excisional biopsy without thoracotomy. Ten patients (83%) received radiotherapy as a curative intent, and the median dose was 60 Gy. Systemic chemotherapy was administered to four patients (33%), and the majority (75%) of the regimens contained cisplatin. The 3-year overall survival rate was 25%. Histological subtype (low-grade versus high-grade), surgical resection (complete versus incomplete), radiotherapy and chemotherapy were evaluated as prognostic factors in a univariate analysis. Low-grade histology and complete resection were good prognostic factors, although these were not statistically significant. Patients who received radiotherapy had a better outcome than those who did not. The major sites of recurrence were the pleura and pericardium. Recurrence within the radiation field was observed in one of seven patients in whom failure patterns could be evaluated. Complete resection is mandatory if possible. Radiotherapy plays an important role in treating thymic carcinoma in terms of reducing local recurrence and prolonging survival time. Establishment of an innovative treatment protocol that includes chemotherapy is necessary to control intrathoracic relapse and distant metastasis. (authors)

  5. 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

    Sarcomatoid renal cell carcinoma (SRCC) is an aggressive tumor variant thought to arise predominantly from differentiation of clear cell carcinoma. A few reports of SRCC asso-ciated with non-clear cell tumors led to the presumption that SRCC may arise from any renal cell carcinoma, although direct evidence of this is lacking. We report a case of a 70-year-old male patient, who presented with acute left upper quadrant abdominal pain and was diagnosed to have SRCC after pathological examination...

    The prognosis of salivary gland carcinomas is difficult to assess. Simple mucin-type carbohydrates (T and sialosyl-T antigens, Tn and sialosyl-Tn antigens) have been shown to be of value in predicting prognosis for carcinomas in other locations. We studied the prognostic significance of the...... expression of these structures in a retrospective study of 133 patients with salivary gland carcinomas, using immunohistochemistry and a panel of well-defined monoclonal antibodies (MAbs) on formalin-fixed paraffin-embedded tissues. Sialosyl-Tn, T and sialosyl-T antigens were not correlated with prognosis...

    External auditory canal (EAC) carcinomas are relatively rare conditions lack on established treatment strategy. We analyzed a treatment modalities and outcome in 32 cases of EAC squamous cell carcinoma treated between 1980 and 2008. Subjects-17 men and 15 women ranging from 33 to 92 years old (average: 66) were divided by Arriaga's tumor staging into 12 T1, 5 T2, 6 T3, and 9 T4. Survival was calculated by the Kaplan-Meier method. Disease-specific 5-year survival was 100% for T1, T2, 44% for T3, and 33% for T4. In contrast to 100% 5-year survival for T1+T2 cancer, the 5-year survival for T3+T4 cancer was 37% with high recurrence due to positive surgical margins. The first 22 years of the 29 years surveyed, we performed surgery mainly, and irradiation or chemotherapy was selected for early disease or cases with positive surgical margins as postoperative therapy. During the 22-years, 5-year survival with T3+T4 cancer was 20%. After we started superselective intra-arterial (IA) rapid infusion chemotherapy combined with radiotherapy in 2003, we achieved negative surgical margins for advanced disease, and 5-year survival for T3+T4 cancer rise to 80%.

  9. 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.)

  13. Clear cell carcinoma of the endometrium: an uncommon entity with a favorable prognosis

    International Nuclear Information System (INIS)

    From 1969 to 1978, 345 patients with endometrial carcinoma were treated at the Medical College of Virginia. Twenty-three of these were clear cell carcinoma (6.6%). Previous reports indicate a poor prognosis with this histological entity. In this series no differences were noticed between clear cell carcinoma and classical adenocarcinoma with regard to variables such as age, race, stage at presentation or response to treatment. Clear cell carcinoma is a distinct histological entity and does not appear to be different than classical adenocarcinoma in its behavior and response to therapy. It is recommended that these tumors be managed by a combination of surgery and radiotherapy

  14. Invasive cervical carcinoma (Stages IB-IIB)

    International Nuclear Information System (INIS)

    In the patients with invasive cervical carcinoma, the accurate assessment of parametrial invasion greatly affects the therapeutic choice between surgery and radiation therapy. As a matter of fact, surgery is usually performed only in the patients with carcinoma confined to the cervix, whereas those with parametrial involvement, or more advanced stages, are treated with radiation therapy. This prospective study was aimed at investigating the comparative adequecy of CT and MR imaging in assessing parametrial status in the patients with invasive cervical cancer. Twenty-one consecutive patients, with histologic diagnosis of cervical carcinoma, were investigated. All of them were clinically considered as having invasive cervical cancer (FIGO stage IB-IIB) and subsequently underwent surgery. In all cases, detailed histology of the parametrium was obtained. Pathological data were compared with CT and MR findings in all cases. As for assessing parametrial involvement by cancer, CT had 62% accuracy, 63% sensitivity, and 60% specificity, versus MR imaging 81% accuracy, 69% sensitivity, and 80% specificify. Therefore, MR imaging appears to be superior to CT in assessing the parametrial status of patients with invasive cervical carcinoma; the method yields valuable information for treatment planning

    International Nuclear Information System (INIS)

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

    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.

    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.

  18. 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

    Pulmonary sarcomatoid carcinomas are a rare group of tumors accounting for about one percent of non-small cell lung carcinoma (NSCLC). In 2015, the World Health Organization classification united under this name all the carcinomas with sarcomatous-like component with spindle cell or giant cell appearance, or associated with a sarcomatous component sometimes heterologous. There are five subtypes: pleomorphic carcinoma, spindle cell carcinoma, giant cell carcinoma, carcinosarcoma and pulmonary blastoma. Clinical characteristics are not specific from the other subtypes of NSCLC. Epithelial to mesenchymal transition pathway may play a key role. Patients, usually tobacco smokers, are frequently symptomatic. Tumors are voluminous more often peripherical than central, with strong fixation on FDG TEP CT. Distant metastases are frequent with atypical visceral locations. These tumors have poorer prognosis than the other NSCLC subtypes because of great aggressivity, and frequent chemoresistance. Here we present pathological description and a review of literature with molecular features in order to better describe these tumors and perhaps introduce new therapeutics. PMID:26778815

  12. 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

  13. Late local recurrence after radiotherapy for tongue and early glottic carcinoma

    International Nuclear Information System (INIS)

    From 1967 through 1982, 633 patients with tongue carcinoma and 330 patients with early (T1T2N0) glottic carcinomas were treated at the Department of Radiology, Osaka University Hospital. Of these 821 patients, 329 patients with tongue carcinoma and 221 patients with early glottic carcinoma survived at 5 years after radiotherapy without local recurrence. For tongue carcinoma, patients were divided by T category. For early glottic carcinoma, patients were divided by the tumor response at 40 Gy. Late local recurrence occurred in 23 of 329 patients (7%) with tongue carcinoma, and in 9 of 221 patients (4%) with early glottic carcinoma. For tongue carcinoma, late recurrence occurred in 19 of 249 patients (8%) in stage I and II, and 4 of 80 patients (5%) in stage III and IV. For glottic carcinoma, late recurrence occurred in 8 of 137 patients (6%) with tumor clearance at 40 Gy and 1 of 63 patients (2%) with tumor persistence at 40 Gy. The incidence of double cancer was also evaluated. Of 329 5-year survivors with tongue carcinoma, 39 patients (12%) had another malignancy, and 26 patients of 221 5-year survivors with early glottic carcinoma (12%) had also another malignancy. Of 39 double primaries of tongue carcinoma, 10 patients (26%) had head and neck malignancies, and none of 26 double primaries of early glottic carcinoma. Late local recurrence was not rare in tongue and early glottic cancer. Poor prognostic group showed lower incidence of late recurrence than good prognostic group. This result suggests that secondary tumor at the same site of primary tumor is late local recurrence. (orig./MG)

    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

  15. Carcinoma of the penis and male urethra

    International Nuclear Information System (INIS)

    Early carcinoma of the penis can be effectively treated with either surgical resection or radical radiation therapy. Preservation of a functioning organ is the principal advantage of treatment by irradiation. The advantages of surgical resection include expediency and, in advanced primary lesions, superior local control. In reliable patients amenable to frequent follow-up, use of radiation therapy followed by salvage surgery does not appear to compromise cure rate or survival. As a rule, regional lymphatics should be treated therapeutically rather that prophylactically. Surgical resection is the treatment of choice in patients with resectable nodal disease. Use of electric irradiation of the regional lymphatics in patients who are at high risk of involvement (advanced primary high grade lesions) should be tested in a trial before it can be advocated in daily practice. Therapeutic considerations applicable to carcinoma of the penis are also applicable to carcinoma of the distal urethra. Lesions of the proximal urethra carry an ominous prognosis; an optimal therapeutic strategy (which probably will entail a combination of radiation therapy plus surgery) remains to be defined

    Metastases of esophageal carcinoma to the skeletal muscle are rare,but the incidence may be increasing because of better diagnosis resulting from widespread use of positron emission tomography/computed tomography (PET/CT).A cohort of 205 patients with esophageal carcinoma treated at our center who had PET/CT between 2006 and 2010 was retrospectively evaluated for the presence of skeletal muscle metastases.Four patients had skeletal muscle metastases of esophageal carcinoma,including two patients with squamous cell carcinoma.In another patient with squamous cell carcinoma of the esophagus and synchronous skeletal muscle metastases,muscle metastases were subsequently shown to be related to second primary pancreatic adenocarcinoma.In all cases,skeletal muscle metastases were the first manifestation of systemic disease.In three patients palliation was obtained with the combination of external beam radiation therapy,systemic chemotherapy or surgical resection.Skeletal muscle metastases are a rare complication of esophageal carcinoma.

    A total of 122 patients with pharyngeal cancer (55 cases), carcinoma of the oral tongue (28 cases) and carcinoma of the oral cavity (39 cases) were treated by external irradiation at the Department of Radiology, Kumamoto National Hospital. In the retrospective study, therapeutic results in pharyngeal cancer (39 cases), in carcinoma of the oral tongue (20 cases) and in carcinoma of the oral cavity (30 cases) were analyzed. 1) Thirty-nine cases of pharyngeal cancer consitituted 9 cases of epipharyngeal cancer, 17 of mesopharyngeal cancer and 13 of hypopharyngeal cancer. The five-year survival rate was 35 % for epipharyngeal cancer, 13 % for mesopharyngeal cancer and 10 % for hypopharyngeal cancer. 2) Twenty cases of carcinoma of the oral tongue were treated by external irradiation and intraoral electron therapy. The five-year survival rate was 28 %. Three cases survived more than five years ; 2 were preoperative irradiation and 1 undergoing a curative irradiation was salvaged with surgery. 3) Thirty cases of carcinoma of the oral cavity consitituted 10 cases of carcinoma of the floor of the mouth, 9 of carcinoma of the cheek mucosa, 7 of carcinoma of the gum, 2 of carcinoma of the hard palate and 2 of carcinoma of the lip. An overall survival rate was 27 %. Five cases survived more than five years ; 3 were carcinoma of the gum and 2 were carcinoma of the cheek mucosa.

    Silent pituitary corticotroph carcinomas are rare, with only six previously described cases in the literature. We report a patient with a silent pituitary corticotroph adenoma treated with multiple trans-sphenoidal resections. Twelve years after her initial presentation, she returned with leptomeningeal metastases to the posterior fossa, foramen magnum, and numerous other subarachnoid locations involving the spine. Histopathology obtained from the metastatic foci was identical to previous trans-sphenoidal specimens - consistent with the diagnosis of corticotroph pituitary carcinoma. A carboplatin and etoposide chemotherapy regimen successfully arrested disease progression and produced regression of multiple radiographically documented leptomeningeal deposits. To the authors' knowledge, this is the first report of a patient with silent pituitary carcinoma treated successfully with chemotherapy. PMID:27150544

    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.
