The subject of this work is the therapeutic success of radiation therapy, respectively operation, with uterine carcinoma. For the evaluation 938 patients of the Marburg University Radiation Clinic from the years 1960 to 1979 were included. The 5-year survival rate with collum carcinoma was 56.99% (stage I 79.62%, II 57.29%, III 31.13%, IV 5.88%). With patients with corpus carcinoma the 5-year survival rate was 74.27% (stage II 80.79%, I 77.50%, III 57.50%, IV 30.00%). The results of various radiotherapeutic methods ('Duesseldorf method', 'Marburg method') were discussed. With respect to the international results published in 'Annual Report' the Marburg results for the treatment of collum carcinoma (the 5-year survival rates) are at world level, and the successes in the treatment of corpus carcinoma are clearly better.

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

Between 1967 and 1976, 82 patients who had epithelial carcinoma of the ovary and were treated with surgery and postoperative radiation therapy, respectively, were studied. Of these patients, 35% had Stage I disease, 16% Stage II, 45% Stage III, and 4% Stage IV. Survival at five years was 96% for Stage I patients, 60% for Stage II, and 60% for Stage III. No stage IV patient survived past two years. Patients with Stage III disease treated by whole-abdominal irradiation with a pelvic boost did better than those who received 3000 rad or less to the pelvis. Radiation therapy continues to be an important treatment modality in epithelial carcinoma of the ovary, particularly in patients with minimal tumor burden. Long-term complications were primarily abdominal

The study is concerned with immunologic status (cell-mediated and humoral immunity) as a factor influencing the choice of scheme of treatment for carcinoma of cervix uteri. The indexes of immunocompetence should be taken into account in planning the differential treatment of precancer and early forms of carcinoma of cervix uteri. Radiation treatment exerts an immunosuppressive effect. However, immunologic indexes are not affected considerably by laser destruction or surgery. Cryodestruction has a beneficial effect on cell-mediated immunity. Considering these effects as well as the long-term results of different orocedures of treatment, laser coagulation, cryogenic destruction or diathermoconization should be recommended for management of carcinoma in situ of cervix uteri, and extensive extirpation of the uterus, unattended by radiation, for Tla

To improve the surgical rate and the quality of life (QOL) for patients with advanced low rectal carcinoma, we investigated whether preoperative treatments (irradiation and hyperthermia and 5-fluorouracil (5-FU) suppository, irradiation and hyperthermia, irradiation and 5-FU suppository, irradiation alone and 5-FU suppository alone) were useful. The tumor shrinkage rate after preoperative treatments was highest in the irradiation, hyperthermia and 5-FU suppository group. Pathologically complete regression was observed in the 2 of 18 cases (12%). According to our criteria of histological changes, the irradiation, hyperthermia and 5-FU suppository group showed the greatest effectiveness. The 4 year postoperative survival rate and the 4 year local recurrence rate were 100% and 8% in the irradiation, hyperthermia and 5-FU suppository group and the data suggest that these results were the best of the 5 treatments. After the carcinoma was shrunk after irradiation, hyperthermia and 5-FU suppository, the patients could receive curatively a sphincter-saving operation (super-low anterior resection and transanal rectal resection). The fecal continence of 7 patients after sphincter-saving operations was increased as good by manometric study, defecography and clinical evaluation. In conclusion, our data suggest that the preoperative combined treatment of irradiation, hyperthermia and 5-FU suppository prevents local recurrence and increases the possibility of a sphincter-saving operation for advanced rectal carcinoma.

1994-01-01

584 patients with carcinoma of the larynx treated with surgery of the larynx and bilateral functional neck dissection, between 1980 and 1989, were reviewed. 127 of them had histopathologically proven metastases to the lymph nodes. Pathologic stating of cervical metastases was as followed: pN1 - 24.5%, pN2a - 10.2%, pN2b - 26%, pN2c - 29.1%, pN3 - 10.2%. Of the 127 patients 89% were treated by surgery and postoperative radiation, 20% had surgery alone, that means radical or conservative neck dissection. In the group with combined treatment the results were much better than in cases of surgery alone, in advanced cases (pN2c, pN3) - 43.2% and 10% 5-year survival rate respectively. In the group of less advanced changes in the neck the difference in survival rate in the group with and without radiotherapy was very small. The results indicate that postoperative radiotherapy has great effect on survival rate in advanced cases of cervical metastases. (author)

2001-01-01

In this retrospective study the results of primary and salvage treatment of oropharyngeal carcinoma were evaluated. A total of 289 consecutive patients (103 females and 186 males) were included in the study. Most tumours originated in the tonsil area (58%) and comprised stages I 8%, II 19%, III 46% and IV 28%. The primary treatment was delivered with curative intent in 276 cases (96%). Of these, 266 received primary radiotherapy. The median radiation dose was 62 Gy, given as laterally opposed fields to the primary tumour and bilateral neck. Eight patients were treated with primary surgery and two with chemotherapy as part of a curatively intended treatment programme including radiotherapy. Six patients received palliative treatment, and seven were not treated at all. Out of 276 tumours treated with curative intent, 173 reappeared; 72% recurred in T position, 38% in N position, and 12% at distant metastatic sites, some in combination. Salvage surgery was possible in 52 patients, and 24 treatments were successful. Salvage radiotherapy or cryotherapy was used in 22 patients and 4 were controlled. For the entire group, the 5-year locoregional tumour control, disease-specific survival and overall survival rates were 38%, 44% and 31%, respectively. For patients treated with curative intent, clinical T- and N-stage, stage, tumour size, gender, age, and pretreatment haemoglobin were significant prognostic parameters in a univariate analysis. The Cox multivariate analysis showed that T-stage, N-stage and gender were independent prognostic factors. It is concluded that T-stage, N-stage and gender are significant independent prognostic factors. The primary control of the carcinoma in the T-position is crucial for overall success, but salvage surgery is found to have a favourable success rate in patients suitable for relapse treatment

Skin carcinoma, particularly basal cell carcinoma, and its treatment can result in large defects of the hairy skull. A 53-year-old man is described who was surgically treated for a large basal cell carcinoma invading the skin and underlying tissue at the top of the hairy skull. Treatment consisted of resecting the tumor and external part of the skull bone. To protect the brain and to cover the defect of the hairy skull, an acrylic resin skull prosthesis with hair was designed to mask the defect. The skull prosthesis was retained on 8 extraoral implants placed at the margins of the defect in the skull bone. The patient was satisfied with the treatment outcome.

Nori, Dattatreyudu

1995-01-01

Purpose: This course will review current staging, prognostic factors, treatment options, rationale and management strategies for patients with endometrial carcinoma. Carcinoma of the endometrium is the most common gynecological malignancy in the U.S. About 40,000 new cases are diagnosed each year. The majority of the patients at the time of diagnosis have early stage disease. Staging of endometrial cancer has been modified three times by FIGO over the past 25 years. Materials and Methods: Various treatment options will be reviewed and current available literature on results and complications of various treatments will be discussed. The standard treatment for operable patients with carcinoma of the endometrium is total abdominal hysterectomy-bilateral salpingoopherectomy with regional lymph node staging. There is considerable controversy regarding the role of radiation as an adjuvant treatment. Various combinations of surgery and radiation have been used in the past. With better knowledge and understanding of the natural history of the disease and significance of prognostic factors, three different risk groups have been identified; low risk, intermediate risk, high risk. Postoperative radiation has been shown to decrease local failures and improve survival in the majority of the intermediate risk group and high risk group of patients. There is considerable controversy on the role of intravaginal radiation. Considerable experience has been accumulated in the use of High Dose Rate fractionated intravaginal treatment. Results: The results of combined surgery and radiation treatment have been very satisfactory with associated minimal complication rate. The long term published data on results and complications will be discussed. Conclusion: Various treatment strategies for different prognostic groups will be discussed. The advantages and disadvantages of low dose rate versus high dose rate brachytherapy, intracavitary versus external beam radiation therapy will be

Abstarct: Background and purpose: Tumor recurrence after surgery for cervical carcinoma is associated with high fatality and morbidity, forming a major therapeutic challenge. This paper presents our experience with treatment of this patient group by salvage radiotherapy with curative intent. Materials and methods: Thirty-five patients with a pelvic recurrence after hysterectomy received high-dose radiotherapy. A retrospective analysis of long-term outcome and prognostic factors was performed. Results: After a median follow-up period of 12.1 years, actuarial 2-,5- and 10-year overall survival rates were 66%, 43% and 33%; disease-free survival rates were 62%, 45% and 41%, respectively. Pelvic control rates at 2-,5- and 10-years were 77%, 69% and 62%. Unfavorable prognostic factors on univariate analysis for survival were: recurrence extending to the pelvic wall versus central recurrence, early recurrence after surgery, external boost versus brachytherapy boost, low total dose and high age. Only a brachytherapy boost and a long interval between surgery and recurrence were significant on multivariate analysis. Severe complications (≥grade 3) were seen in 6 patients (17%; actuarial after 5 years, 21%). Conclusions: Salvage radiotherapy for recurrent cervical carcinoma following surgery may result in 40-50% long-term disease-free survival and an acceptable risk of severe treatment complications, even in patient with recurrences extending to the pelvic wall

Full Text Available The most important prognostic factors for clear cell carcinoma (CCC are clinical and morphological signs and clinical stage of the disease. Analyses of 5-year survival in patients with I stage of CCC is 69 %, in II stage – 55 %, in III stage – 14 % and in IV stage – 4 % patients. We analyzed distant results of treatment of 71 patients with CCC and of 25 patients with mixed malignant ovaries neoplasm with obligatory clear cell component taking into consideration main clinical and morphological sings of disease. On the base of performed reseal we revealed that morphological structure of the tumors and stage of the disease exerted heist influence on the exponent of survival of the patients with clear CCC ovaries neoplasm. Besides, there is a correlation between exponent of patients’ survival and radicalized of surgery, character of tumor growth, differentiation degree, cell anaplasia and mitotic activity of tumor cells.

Treatment resistance in urothelial carcinoma: an evolutionary perspective.

The emergence of treatment-resistant clones is a critical barrier to cure in patients with urothelial carcinoma. Setting the stage for the evolution of resistance, urothelial carcinoma is characterized by extensive mutational heterogeneity, which is detectable even in patients with early stage disease. Chemotherapy and immunotherapy both act as selective pressures that shape the evolutionary trajectory of urothelial carcinoma throughout the course of the disease. A detailed understanding of the dynamics of evolutionary drivers is required for the rational development of curative therapies. Herein, we describe the molecular basis of the clonal evolution of urothelial carcinomas and the use of genomic approaches to predict treatment responses. We discuss various mechanisms of resistance to chemotherapy with a focus on the mutagenic effects of the DNA dC->dU-editing enzymes APOBEC3 family of proteins. We also review the evolutionary mechanisms underlying resistance to immunotherapy, such as the loss of clonal tumour neoantigens. By dissecting treatment resistance through an evolutionary lens, the field will advance towards true precision medicine for urothelial carcinoma.

The methods and results of treatment for cancer of the cervical esophagus differ from those for cancer of the thoracic esophagus. Our objective was to retrospectively review the outcome for cervical esophageal cancer patients treated with radiotherapy. Twenty-seven patients with carcinoma of the cervical esophagus treated with definitive radiotherapy from 1988 to 2002 were enrolled in the study. Clinical stage (UICC 1997) was stage I in five, II in six, III in 12 and IV in four. Concurrent head and neck malignancy was found in six patients (22%). The mean radiation dose was 66 Gy. Concurrent chemotherapy (cisplatin and 5-fluorouracil) was performed in 23 patients. The actuarial overall survival rates at 1, 3 and 5 years were 55.6%, 37.9% and 37.9%, respectively, with a median survival of 13.9 months. In the patients with stage I, the 3-year and 5-year survival rates were 75% and 75%, respectively. With univariate analysis, only two of the possible prognostic factors were found to actually influence survival: performance status (p<0.01) and tumor length (p<0.01). The survival of patients with cervical esophageal cancer remains poor. It is thought that organ preservation is possible by definitive chemoradiation for early cancer

Clinical results of the use of mitotane for adrenocortical carcinoma

Directory of Open Access Journals (Sweden)

Kasperlik-Zaluska A.A.

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

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

Brachytherapy as sole treatment modality in initial cervix carcinoma

Heredia Z, A.

1993-01-01

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

1994-01-01

Background: To exam the effect of radioactive iodine treatment for thyroid remnant ablation and/or distant metastasis. A total of 134 well-differentiated thyroid cancer patients with cervical lymphnode metastasis at the time of diagnosis were retrospectively reviewed at Chang Gung Medical Center in Taiwan from 1977 to 1995. Methods: Among them, 126 cases were papillary carcinomas and 8 cases were follicular carcinomas. The mean age was 37.0 ± 14.6 years old. After the operation, 127 (95 %) patients received 131 I treatment (mean dose: 146.6 ± 109.5 mCi, range 30 - 550 mCi) and long-term follow-up. The mean follow-up period is 5.9 ± 3.9 yrs. All patients were restage at the end of 1995. Clinical biochemical results were also analyzed. Results: Among 127 cases who received postoperative radioactive iodine treatment, the majority of cases (92.5 % in papillary ca. vs. 57.1 % in follicular ca.) improved to stage I, 11 (8.6 %) cases remained on the same disease and stages. 13 cases (10.2 %, 10 papillary and 3 follicular) deteriorated to stage III or IV. However, in the non-treatment group, only 33.3 % of papillary carcinoma patients improved to stage I and 16.7 % of the patients remained as stage II. There were 5 cases (3.7 %) of mortality. Two cases with stage IV papillary carcinomas died of metastatic or recurrent malignancy, and the other 2 cases with stage I or III papillary carcinomas died of tracheal cancer or valvular heart disease. One patient with stage IV follicular carcinoma died of cerebral vascular accident. Conclusions: Radioactive iodine ( 131 I) treatment plays a significant role in the management of well-differentiated thyroid carcinoma patients with cervical lymphnode metastasis. The effect of postoperative 131 I treatment on papillary carcinoma was better than that on follicular carcinoma. The optimal dosage and frequency of radioactive iodine treatment warrant further study. (author)

Background and Purpose: In a retrospective study the role of radiation therapy for the treatment of primary tracheal carcinoma was investigated. Patients and Methods: Between 1984 and 1997, 25 patients with primary tracheal carcinoma were treated with external beam radiotherapy (17 squamous-cell carcinoma [SCC], 8 adenoid cystic carcinoma [ACC], median dose SCC 60 Gy, ACC 55 Gy). An additional brachytherapy boost was carried out in 10/25 patients (median dose SCC 18 Gy, ACC 15 Gy). Ten patients underwent operative treatment. Results: The median survival (Kaplan-Meier) for patients with SCC was 33 months (ACC 94.2). The 1-, 2- and 5-year survival rates (Kaplan-Meier) for patients with SCC were 64.7% (ACC 85.7%), 64.7% (ACC 85.7%), and 26% (ACC 85.7%). Patients with ACC and patients with a complete remission after treatment had a significantly better survival probability (log rank test, p [de

Purpose/Objective: To evaluate the place of conservative treatment in invasive lobular carcinoma. Materials and Methods: From 01/01/85 to 31/12/92, 109 patients with clinically and mammographically unifocal invasive lobular carcinoma of the breast (T<35 mm) underwent tumorectomy, axillary dissection and radiation therapy; they received an adjuvant treatment in case of nodal involvement (n = 31) or lack of estrogen and progesterone receptors (n = 16). The entire breast received 50 Gy with a systematic boost of 10 Gy. Results: With a median follow-up of 86 months, we observed 11 isolated local recurrences (T0 = (3(19)), T1 = (6(41)), T2 = (2(49))), 7 local recurrences associated with metastases (T1 = (3(41)), T2 = (4(49))) and 7 cases of metastatic diseases (T1 = (4(41)), T2 = (3(49))). Among the 11 patients with isolated local recurrence, 7 are alive with no evidence of disease after salvage mastectomy. Nine contro-lateral breast cancers occurred, 2 synchronous and 7 metachronous. The 5-year actuarial local relapse free survival, metastase free survival and overall survival are respectively 87.3%, 89.5% and 92.5%, whatever histological subtypes. These results are comparable to those obtained in 1393 cases of infiltrating ductal carcinoma similarly treated during the same period in our institute, except for local relapse (87.3% vs 91%, p = 0.008). Conclusion: Conservative treatment for invasive lobular carcinoma of the breast (T<35 mm) is appropriate in the absence of clinical or mammographic multifocality

Randomized investigation in two patients groups suffered with endometrial carcinoma (EC) of 1-2 and 3-4 stages (FIGO, 1977) is performed. Effect of blood lymphocytes contrasuppression before and after combined treatment (operation + radiotherapy) is studied as well as delayed therapy results. A part of patients was immunized with tularemia live vaccine (TLV) before treatment. It is shown that the delayed combined treatment results in EC patients correlate with contrasuppression effect revealed in them before therapy. It is concluded that the index of contrasuppression effect revealability and delayed results of combined therapy in EC patients immunized with TLV before therapy have an expressed tendency to improving as compared to nonimmunized patients of the same stages [ru

This study reports on 5 years experience of the treatment of carcinoma of the cervix and poor-risk carcinoma of the body of the uterus using a combination of external beam radiotherapy and high-dose-rate intracavitary 60Co-brachytherapy using the Cathetron since 1979 at the Middlesex Hospital, London. Despite a reduction in external beam dose of 20% since 1979, survival rates for both diseases remain unchanged and also compare favourably with those of other centres; they are 70.02% for carcinoma of the cervix of all stages except Ia, and 81.17% for 'poor-risk' carcinoma of body of uterus of all stages. The complication rates were acceptable. Analysis of the results of treatment by stage of disease in those patients with carcinoma of the cervix revealed that, except for Stage I cases, the results were comparable with those reported in the literature. The reason for the poor results in Stage I was found to be due to the high proportion of patients of 35 years of age and under with Stage I disease who fared significantly worse than older patients.

Background: Nasopharyngeal Carcinoma (NPC) is a common malignant neoplasm of the head and neck that occurs most commonly in people in the South Eastern Asia but its condition in Iran is not much clear. Objective: In this retrospective study, we evaluated the treatment characteristics determining the outcome in patients with NPC. Patients and Methods: In this retrospective study, we reviewed the records of one hundred and seven patients with biopsy proven diagnosis of NPC who were referred to the radiation oncology department, Nemazee Hospital, Shiraz University of Medical Sciences, Iran, during the time period from January 1985 to December 2000. Eighty five patients (79.4%) received 60-70 Gy radiation (1.82 Gy/fraction, one fraction per day, and 5 fractions per week). Sixty-two patients (57.5%) received radiotherapy combined with adjuvant chemotherapy which consisted of cisplatin and 5-fluorouracil. Eighty-six patients (80.4%) had WHO II-III histopathologic diagnosis. According to the AlCC 1997 staging system, 4 (3.6%), 3 (2.7%), 33 (30.8%) and 67 (62%) patients were in stages I, II, III and IV, respectively. Results: With a median follow-up of 12 months, the 2-year overall and disease-free survival rates were 35% and 21%, respectively. According to the multivariate analysis for overall survival, patients under 40 years had a better prognosis (p=0.041). Node stage and stage of disease were significant prognostic factors (p=0.0001. On multivariate analysis for disease-free survival, age and node stage were significant prognostic factors. The patients who received more than 60 Gy radiation had a better prognosis (p=0.02), however; sequential adjuvant chemotherapy had no impact on survival and response (p=0.6). Conclusion: Our experience confirmed earlier reports showing poor outcomes for locoregionally advanced nasopharyngeal carcinomas. This study failed to demonstrate improvement in the outcome regarding overall and disease-free survival by adding sequential

Full Text Available A select group of patients with upper tract urothelial carcinoma may be appropriate candidates for minimally invasive management. Organ-preserving endoscopic procedures may be appropriate for patients with an inability to tolerate major surgery, solitary kidney, bilateral disease, poor renal function, small tumor burden, low-grade disease, or carcinoma in situ. We review the published literature on the use of topical treatment for upper tract urothelial carcinoma and provide our approach to treatment in the office setting.

The treatment results were compared in 77 patients with maxillary sinus squamous cell carcinoma (MC) and 53 patients with squamous cell carcinoma arising from the oral part of the upper law (OC). Both sets of patients received radiotherapy alone, or radiotherapy combined with surgery and/or chemotherapy. Computerized tomography was useful for the definition of the treatment volume. Intraarterial chemotherapy was given in 89 of 130 patients and in these patients the total radiation dose was reduced by about 10 Gy. No difference was found in the 5-year survival rate between the MC (65%) and the OC (66%) groups. The cumulative incidence of local failure was higher in MC (36%) than in OC (26%), whereas the ultimate incidence of neck node metastasis was higher in OC (43%) than in MC patients (18%). Half of the inoperable patients (9/18) were older than 80 years and had contraindications to anaesthesia and major surgery. The local recurrence rate was high in the inoperable MC patients (6/8). Contralateral simus cancers occurred in 4 patients in the MC group. (orig.)

Objective: To show the computed tomography (CT) usefulness after treatment with transcatheter arterial quimioembolization and radiofrequency ablation of hepatocellular carcinoma. Material and methods: In a period between march 2006 to april 2008 a total of 90 patient presenting 148 nodular lesions with diagnosis of hepatocellular carcinoma were controlled with triphasic CT. All the lesions were treated with minimally invasive procedure. For the treatment, the patients were classified in two groups following Milan criteria. The first group, constituted by 75 patients with 109 nodules, was treated with quimioembolization. The second group, of 15 patients with 25 nodules, was treated with radiofrequency ablation. In our population, a subgroup of 10 patients was treated with both methods. Results: Of 90 patients after CT control on a month, 3 months and for each 3 months during 2 years, on 63 cases (70%) was observed homogeneous accumulation of iodized oil, partial defect without enhancement or absence of enhancement on treated lesions. In these patients a new treatment after initial one was not performed. The remaining 27 patients (30%) underwent new treatment because we founded partial defect or absence of iodized oil with enhancement or peripheral enhancement on arterial phase in treated lesions. In this last group, 16 treated patients (17.7%) had new nodular enhancement on the remaining hepatic parenquimal. Conclusion: The CT unenhanced and the arterial phase on a month and for each 3 months, allow monitoring the effectiveness, residual disease and/or relapse of hepatocellular carcinoma after minimally invasive treatment.

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

The survival rates of 36 patients with early cervical carcinoma who had undergone total hysterectomy and bilateral salpingoophorectomy (THBSO) were compared to the survival rates of 41 patients who were subjected to the radical operation. As an integral part of their therapy both groups postoperatively received adequate doses of external beam supervoltage irradiation. Satisfactory results were obtained in both groups of patients. According to these results THBSO followed by postoperative radiotherapy is adequate treatment for early cervical carcinoma. In comparison to the radical operation or curietherapy alone this type of treatment has the advantage of requiring less surgical or radiotherapeutic expertise; it probably is associated with less morbidity

The purpose of this study was to evaluate the outcome of primary treatment and treatment of recurrences in patients with nasopharyngeal carcinoma. The material included 149 consecutive patients seen at the Aarhus University Hospital from 1963 to 1991 (49 females and 100 males). The stage distribution was: Stage I -9%, II-3%, III-28%, and IV-60%. Primary treatment was delivered with curative intent in 145 patients (97%). Persistent or recurrent disease after primary radical treatment was observed in 82 of the patients; 54% at the T-level, 40% at the N-level, and 33% at the M-level. A curative salvage attempt was carried out in 14 patients only, all with nodal recurrence: surgery in 8 patients (4 controlled) and radiotherapy in 6 patients (2 controlled). The 5-year local tumour control, locoregional tumour control, disease-specific survival rate and the overall survival rate for the patients treated with curative intent were 66%, 53%, 50% and 43%, respectively. Most of the patients (88%) had poorly differentiated tumours and these patients had the best prognosis. A major complication in three patients was radiation-induced myelopathy due to high-dose radiation delivered to the brain stem. Significant positive prognostic factors for treatment outcome in univariate analyses were early T-classification, small clinical stage, poor differentiation and low age. The Cox multivariate analysis showed that early T-categories, low N-categories and poor differentiation were independent, positive prognostic factors. Nasopharyngeal carcinoma is curable with primary radiotherapy; patients with poorly differentiated tumours have the best prognosis. Only a few patients were salvaged after recurrence. The factor most essential for success is primary control of the disease at the T- and N-levels

It has been considered that oral cancer is cured if more than five years pass without recurrence or metastasis after the initial treatment. Treatment results are usually evaluated as a 5-year survival rate, but we sometimes find recurrence more than five years after the initial treatment. We retrospectively investigated treatment results by long-term follow-up of advanced squamous cell carcinoma of the oral cavity after radical surgery, and analyzed the relation between the period of follow-up and the time to recurrence. One hundred and sixteen patients with advanced squamous cell carcinoma of the oral cavity were enrolled between November 1994 and October 2004 in this study. Seventy-six patients were Stage III and 40 were stage IV, and the mean age of this cohort was 63.0 years. All patients received radical surgery with or without preoperative chemoradiotherapy and were followed for a minimum of 5 years. Overall actuarial survival of all patients was 77.8% at 10 years. The 10-year cumulative local and regional recurrence rates were 20.1% and 12.9%, respectively. The actuarial loco-regional recurrence rate was the highest within 2 years after initial treatment at 19.0%, and was seen in 3.4% even after 5 years. These results showed that it is necessary to follow-up patients with advanced oral cancer even beyond 5 years after the initial treatment because there was delayed loco-regional recurrence in 3.4%.

Purpose: To retrospectively evaluate the outcome after radical radiotherapy (RT) and surgical salvage and assess the risk of late toxicity for patients with primary subglottic squamous cell carcinoma treated at our center. Methods and Materials: Between 1971 and 1996, 43 patients with primary squamous cell carcinoma of the subglottis (35 men, 8 women) were treated with radical RT. All received megavoltage irradiation, most commonly to a dose of 50-52 Gy in 20 fractions during 4 weeks (39 patients). The median follow-up was 4.2 years. Results: Local control was achieved with RT alone in 24 (56%) of the 43 patients: 7 of 11 with T1, 8 of 12 with T2, 4 of 8 with T3, and 5 of 12 with T4. The 5-year actuarial local relapse-free rate was 52%. Subsequent local control was achieved in 11 of the 13 patients with failed RT and attempted surgical salvage, for an ultimate local control rate of 81.4% (35 of 43). The 5-year overall and cause-specific actuarial survival rate was 50.3% and 66.9%, respectively. No patients developed Grade 3 or 4 late radiation morbidity. Conclusion: These data support the use of primary RT in the treatment of patients with primary squamous cell carcinoma of the subglottis as an appropriate treatment approach providing an option for laryngeal conservation

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

Nasopharyngeal carcinoma (Nc) is a rare disease in Sweden. For evaluation of the treatment outcomes in our NPC patients, 52 new cases that were referred to our department between 1991 and 2002 were retrospectively analysed. Tumor stage, according to the 1997 AJCC staging system, was I in five, II in ten, III in 12 and IV in 25 patients. Majority of the patients (87%) had World Health Organization type II-III tumors. Neoadjuvant chemotherapy was delivered in 33 patients. Thirty-two patients received hyperfractionated accelerated radiation therapy with a median dose of 64.6Gy (1.7Gy/fr bid). Conventional external irradiation with a median dose of 66Gy (2Gy/fr) was delivered to 18 patients. An intracavitary brachy-boost of 4.5-12Gy was delivered to 40 patients. Two patients were excluded from the analysis due to treatment refusal. For the patients with tumor stages I-IVB, the 5-year disease-free and overall survival rates were 61% and 55%, respectively. The 5-year local, regional, and distant relapse-free survival rates were 70%, 92% and 77%, respectively. The most frequent late side effects were xerostomia (98%), otitis (70%) and hearing deterioration (64%). Our data suggest that optimization of the treatment outcomes in NPC patients requires implementation of new therapeutic strategies.

Magnetic resonance imaging following treatment of advanced hepatocellular carcinoma with sorafenib

Directory of Open Access Journals (Sweden)

Full Text Available Hepatocellular carcinomas are highly vascular tumors, showing progressive hypervascularity by the process of neoangiogenesis. Tumor angiogenesis is critical for tumor growth as well as metastatic spread therefore, imaging and quantification of tumor neo-angiogenesis is essential for monitoring response to targeted therapies and predicting disease progression. Sorafenib is a molecular targeting agent used for treating hypervascular tumors. This drug is now the standard of care in treatment of patients with advanced hepatocellular carcinoma. Due to its anti-angiogenic and anti-proliferative actions, imaging findings following treatment with Sorafenib are quite distinct when compared to conventional chemotherapeutic agents. Liver MRI is a widely adopted imaging modality for assessing treatment response in hepatocellular carcinoma and imaging features may reflect pathophysiological changes within the tumor. In this mini-review, we will discuss MRI findings after Sorafenib treatment in hepatocellular carcinoma and review the feasibility of MRI as an early biomarker in differentiating responders from non-responders after treatment with molecular targeting agents.

Unresectable hepatocellular carcinoma is extremely difficult to treat. TheraSphere consists of yttrium-90 (a pure beta emitter) microspheres, which are injected into the hepatic arteries. This article reviews the safety and survival of patients with hepatocellular carcinoma who were treated with yttrium-90 microspheres. Eighty patients were selected from a database of 108 yttrium-90 microsphere-treated patients and were staged by using Child-Pugh, Okuda, and Cancer of the Liver Italian Program scoring systems. Patients were treated with local, regional, and whole-liver approaches. Survival from first treatment was analyzed with Kaplan-Meier and Cox regression methods. Adverse events and complications of treatment were coded by using the Southwest Oncology Group toxicity scoring system. Patients received liver doses ranging from 47 to 270 Gy. Thirty-two patients (40%) received more than 1 treatment. Survival correlated with pretreatment Cancer of the Liver Italian Program scores ( P = .002), as well as with the individual Cancer of the Liver Italian Program components, Child-Pugh class, alpha-fetoprotein levels, and percentage of tumor replacement. Patients classified as Okuda stage I (n = 54) and II (n = 26) had median survival durations and 1-year survival rates of 628 days and 63%, and 384 days and 51%, respectively ( P = .02). One patient died of liver failure judged as possibly related to treatment. Thus, in selected patients with hepatocellular carcinoma, yttrium-90 microsphere treatment is safe and well tolerated. On the basis of these results, a randomized controlled trial is warranted comparing yttrium-90 microsphere treatment with transarterial chemoembolization by using the Cancer of the Liver Italian Program system for prospective stratified randomization.

Background/Aim: The therapeutic effect of intra-arterial injection of 131-iodine-labeled lipiodol for treatment of hepatocellular carcinoma in palliative or adjuvant settings has been promising. We report, the results of an open study of this therapy in cirrhotic patients with small hepatocellular carcinoma. Patients and method: Forty patients with hepatocellular carcinoma were given intra-arterial injections of 131-iodine-labeled lipiodol. These injections were repeated if necessary every 3 months. Tumor response (WHO criteria) was determined on CT scans performed after each treatment and every 3 months during the follow-up. Side effects and the cause of death were recorded. Therapeutic response and survival were analyzed. Results: The median number of treatment was 2 (1-4). There was one complete response, 18 partial responses (47.5% response rate); 19 had stable disease and 2 progressions. Overall survival rates (±CI 95%) at 1, 2 and 3 years were: 90 ± 4.7%, 60.3 ± 8%, and 39 ± 8.3%, respectively. Median survival was 27 months; 25 patients have died (4-56 months), 8 of tumor progression with a multifocal spread in the liver. Tolerance was good except for 2 patients who develop a fatal drug-related pulmonary insufficiency. Conclusion: These data suggest that intra-arterial therapeutic injection of 131-iodine-labeled lipiodol for treatment of hepatocellular carcinoma can provide high rate response and long survival for individuals not eligible for surgery or local treatment

Purpose: The purpose of this work was to examine outcomes in patients with T4 nasopharyngeal carcinoma (NPC) treated with intensity-modulated radiation therapy (IMRT). Methods and materials: Between 2007 and 2010, 154 patients with nonmetastatic T4 NPC were treated with IMRT to a total dose of 70 Gy in 33-35 fractions. In addition, 97 % of patients received concurrent platinum-based chemotherapy. The median follow-up time was 52.8 months. Results: The rates of 5-year actuarial locoregional control, distant metastasis-free survival, progression free-survival, and overall survival (OS) were 81.2, 72.2, 61.9, and 78.1 %, respectively. A total of 27 patients had locoregional recurrence: 85.2 % in-field failures, 11.1 % marginal failures, and 3.7 % out-of-field failures. Fourteen patients with locoregional recurrence received aggressive treatments, including nasopharyngectomy, neck dissection, or re-irradiation, and the 5-year OS rate tended to be better (61.9 %) compared to those receiving conservative treatment (32.0 %, p = 0.051). In patients treated with 1 course of radiotherapy, grade {>=} 3 toxicities of ototoxicity, neck fibrosis, xerostomia, epistaxis, and radiographic temporal lobe necrosis occurred in 18.2, 9.8, 6.3, 2.1, and 5.6 % of patients, respectively. Increased ototoxicity, osteonecrosis, severe nasal bleeding, and temporal necrosis were observed in patients treated by re-irradiation. Conclusion: IMRT offers good locoregional control in patients with T4 NPC. For patients with locoregional recurrence after definitive radiotherapy, aggressive local treatment may be considered for a better outcome. (orig.)

Background: interstitial low-dose-rate (LDR) brachytherapy allows conservative treatment of T1-T2 penile carcinoma. High-dose-rate (HDR) is often considered to be dangerous for interstitial implants because of a higher risk of complications, but numerous reports suggest that results may be comparable to LDR. Nevertheless, there are no data in the literature available regarding HDR interstitial brachytherapy for carcinoma of the penis. Case report: a 64-year-old man with T1 NO MO epidermoid carcinoma of the glans is reported. Interstitial HDR brachytherapy was performed using the stainless hollow needle technique and a breast template for fixation and good geometry. The dose delivered was 18 x 3 Gy twice daily. Results: after 232 days from brachytherapy, the patient was without any evidence of the tumor, experienced no serious radiation-induced complications, and had a fully functional organ. Conclusion: HDR interstitial brachytherapy is feasible in selected case of penis carcinoma, when careful planning and small single fractions are used. (orig.)

Small cell carcinoma is a rare malignant tumor of the larynx. Since this lesion was first described, only 58 cases have been reported in the literature. Between December 1985 and March 1992, five patients with small cell carcinoma of the larynx were treated at the Hospital de la Santa Creu i Sant Pau in Barcelona, Spain. One patient was treated with radiation therapy alone, three patients with chemotherapy and radiation therapy, and one patient with surgery, chemotherapy and radiation therapy. Local and distant control was achieved in only one patient who was observed for 12 months after radiation therapy. Four patients died, one of local disease without distant metastasis at 6 months following treatment, one of local and distant disease at 53 months after radiation therapy, and two of distant metastasis without local disease at 22 and 36 months following treatment. In spite of the fact that only one of the five patients presented in this series is alive and free of disease 12 months following treatment, recent published information suggests that chemotherapy and radiotherapy are currently the most effective form of therapy for small cell carcinoma of the larynx. 16 Refs

For patients with unresectable pancreatic carcinoma, a few kind of treatment including chemoradiation, intraoperative radiation and intra-arterial chemotherapy was done. Chemoradiation using 5FU, CDDP, ADM and radiation to the lesion and liver was performed in 16 patients, showing a response rate of 10%. One-year survivals rate and mean a survival period of this group was 11.7% and 6.6 months respectively. Postmortem autopsy in 6 cases revealed insufficient therapeutic effects in both primary and metastatic site. Because of above-mentioned reasons, chemoradiation therapy to the pancreatic carcinoma, which we did, was estimated as ineffective. (author)

Avelumab is a promising new therapeutic agent for patients with metastatic Merkel cell carcinoma, a rare and aggressive type of neuroendocrine tumor of the skin. Until the recent approval of avelumab (Bavencio), no therapies were approved by the U.S. Food and Drug Administration for the treatment of metastatic Merkel cell carcinoma. In a recent trial, avelumab, an anti-programmed death ligand-1 antibody, demonstrated an objective response in 28 of 88 patients (31.8% [95.9% CI, 21.9-43.1]) with advanced, chemotherapy-refractory Merkel cell carcinoma. Overall, avelumab was well tolerated at a dose of 10 mg/kg administered intravenously every 2 weeks. Serious treatment-related adverse events were reported in 5 patients (6%), but no grade 4 adverse events or treatment-related deaths were reported. Preliminary data evaluating avelumab in chemotherapy-naive patients is also encouraging. Copyright 2017 Clarivate Analytics.

The AIM of this retrospective study is to analyse the indications and the results of treatment of endometrial carcinomas by preoperative radiotherapy. MATERIAL: From 1976 to 1995, 183 patients FIGO stage I or II were treated by preoperative radiotherapy consisting in 95 cases of external radiotherapy (XRT) and brachytherapy (BT) followed by surgery (S) and, in 88 cases of BT alone before surgery, XRT was indicated in cases of grade 2 or 3 and/or cervical involvement. METHODS: XRT was delivered with a 4-fields technique to 40 Gy in 20 fractions with a medial shielding at 30 Gy. BT was done with low dose rate Cs137 and Fletcher-Suit-Delclos applicators with two intra-uterine tubes and vaginal ovoieds. Complications were scored using the French-Italian syllabus. RESULTS: Five-year actuarial survival rates per stage are: Ia=91%, Ib=83%, II=71%, and per grade: G1=80%, G2=79%, G3=90%. Failures were pelvic in 5/183 (2.7%), vaginal in 4 cases (2%) and nodal in 2 cases (1%). Twelve patients developed metastases (6.5%). Complications were analysed during the radiotherapy, after the surgery and with unlimited follow-up. After BT/S, 12 grade 1, 1 grade 2 and 1 grade 3 complications were observed. In the group of patients treated by RT/BT/S, 22 grade 1, 11 grade 2, 4 grade 3 occurred. There is no statistical correlation between complications and parameters of treatment (XRT, hwt, HWT, reference dose to the bladder and rectum, dose rate of brachytherapy). SUMMARY: Preoperative irradiation is an effective and safe treatment of high risk stage I/II endometrial carcinomas. Results seem independent of the pathology grade

Full Text Available We report a rare case of severe hypoglycemia after sunitinib treatment for pancreatic neuroendocrine carcinoma. We describe the initial clinical presentation, laboratory results, pathologic findings, and managment in a patient with a nonfunctioning pancreatic neuroendocrine carcinoma with liver metastases who developed life threatening hypoglycemia after 2 months of sunitinib therapy. A 46-year-old woman presented to the emergency department with loss of consciousness from hypoglycemia. Serum C-peptide and insulin levels at fasting state revealed that the hypoglycemia resulted from endogenous hyperinsulinemia. She had been diagnosed with nonfunctioning pancreatic neuroendocrine carcinoma based on a biopsy of metastatic cervical lymph node and was being treated with sunitinib, a small molecule tyrosine kinase inhibitor. Immunohistochemical stain of the metastatic liver mass demonstrated that the initially nonfunctioning neuroendocrine carcinoma cells had changed into insulin-producing cells after sunitinib therapy. Transarterial chemoembolization of the liver masses and systemic chemotherapy with streptozotocin/adriamycin relieved the hypoglycemia. A nonfunctioning pancreatic neuroendocrine carcinoma was transformed into an insulin-producing tumor after treatment with sunitinib, causing endogenous hyperinsulinemia and severe hypoglycemia.

Objective: To analyze the efficacy, side effects and complications of percutaneous high frequency induced thermotherapy (HiTT) performed under CT guidance involving 36 patients with hepatocellular carcinomas (HCC) and hepatic metastatic lesions. Methods: HiTT was performed in treatment of 36 patients (24 men and 12 women) with 42 hepatocellular carcinoma and hepatic metastatic carcinoma (six patient out of 36 had two nidi). The diameter of the tumors ranged from 1.6 to 7.8 cm (mean, 3.2 cm). The efficacy of HiTT was evaluated with triphasic spiral CT performed 1 month after the procedure. Results: The post-treatment CT scan showed complete necrosis in 33 nidi (78%) out of 42 nidi of hepatocellular carcinoma and hepatic metastatic carcinoma in 30 patients out of 36. Complete necrosis was obtained in 18 (95%) of 19 tumors no larger than 3 cm in diameter, 13 (72%) of 18 tumors between 3.0 and 5.0 cm in diameter. Eleven tumors showed incomplete necrosis. In our study, none of the patients experienced severe complications. All the patients are alive in the follow-up ranging from 2 to 12 months (mean, 7 months). Conclusion: Our research suggests that HiTT can be a safe and effective treatment of hepatocellular carcinomas and hepatic metastatic carcinoma when the lesion is no larger than 3 cm. The treatment is relatively effective for hepatocellular carcinoma between 3 and 5 cm in size. (authors)

Full Text Available Abstract Background The treatment strategy of central lung tumors is not established. Intraluminal brachytherapy (ILBT is widely used for palliative treatment of endobronchial tumors, however, it is also a promising option for curative treatment with limited data. This study evaluates the results after ILBT for endobronchial carcinoma. Method Sixteen-endobronchial carcinoma of 13 patients treated with ILBT in curative intent for 2000 to 2008 were retrospectively reviewed. ILBT using high dose rate 192 iridium thin wire system was performed with 5 Gy/fraction at mucosal surface. The patient age ranged from 57 to 82 years old with median 75 years old. The 16 lesions consisted of 13 central endobronchial cancers including 7 roentgenographically occult lung cancers and 3 of tracheal cancers. Of them, 10 lesions were treated with ILBT of median 20 Gy combined with external beam radiation therapy of median 45 Gy and 6 lesions were treated with ILBT alone of median 25 Gy. Results Median follow-up time was 32.5 months. Two-year survival rate and local control rate were 92.3% and 86.2%, respectively. Local recurrences were observed in 2 lesions. Three patients died due to lung cancer (1 patient and intercurrent disease (2 patients. Complications greater than grade 2 were not observed except for one grade 3 dyspnea. Conclusions ILBT combined with or without EBRT might be a curative treatment option in inoperable endobronchial carcinoma patients with tolerable complication.

A total of 47 patients with a diagnosis of nasopharyngeal carcinoma was treated in Department of Therapeutic Radiology, Seoul National University Hospital during last 4 years. Of the 47 patients, 23(49%) had undifferentiated carcinoma, 20(43%) had squamous cell carcinoma, while 4(8%) had lymphoepithelioma. Most of the patients(71%) has Stage IV disease, cervical lymph node metastases were found in 36(77%) and distant metastasis was found in 1 at the time of diagnosis. Complete response rate after radiotherapy for 47 patients of nasopharyngeal carcinoma was 85.1%. The overall actuarial 3 year survival rates was 0.718 and the disease free actuarial 3 year survival rates was 0.468. Nodal involvement and symptom duration were statistically significant influencing factors for actuarial survival rate. Treatment failures were found in 20 patients (42.6%), local recurrence only in 6(30%), local and neck recurrence in 3(15%), local recurrence with metastasis in 4(20%) and distant metastasis only in 7(35%). Local failures were more frequent in the patients with cranial nerve symptoms (P=0.032). Distant metastases were more frequent with T4 lesions (P=0.047), and with nodal involvement (P<0.01). Retreatment after the tumor recurrence was chemotherapy and/or radiotherapy, two patients retreated for local recurrence were alive without evidence of disease for more than 19 and 44 months after retreatment

Patients diagnosed with localized prostate carcinoma need to interpret complicated medical information to make an informed treatment selection from among treatments that have comparable efficacy but differing side effects. The authors reported initial results for treatment decision-making strategies among men receiving definitive treatment for localized prostate carcinoma. One hundred nineteen men treated with radical prostatectomy (44%) or brachytherapy (56%) consented to participate. Guided by a cognitive-affective theoretic framework, the authors assessed differences in decision-making strategies, and treatment and disease-relevant beliefs and affects, in addition to demographic and clinical variables. Approximately half of patients reported difficulty (49%) and distress (45%) while making treatment decisions, but no regrets (74%) regarding the treatment choice they made. Patients who underwent prostatectomy were younger, were more likely to be employed, had worse tumor grade, and had a shorter time since diagnosis (P Decision-making aids or other interventions to reduce decisional difficulty and emotional distress during decision making were indicated.

Nasopharyngeal Carcinoma (NPC) is a common malignant neoplasm of the head and neck that occurs most commonly in people in the South Eastern Asia but its condition in Iran is not much clear. In this retrospective study, we evaluated the treatment characteristics determining the outcome in patients with NPC. In this retrospective study, we reviewed the records of one hundred and seven patients with biopsy proven diagnosis of NPC who were referred to the radiation oncology department, Nemazee Hospital, Shiraz University of Medical Sciences, Iran, during the time period from January 1985 to December 2000. Eightyfive patients (79.4%) received 60-70Gy radiation (1.8- 2Gy/fraction, one fraction per day, and 5 fractions per week). Sixty-two patients (57.5%) received radiotherapy combined with adjuvant chemotherapy which consisted of cisplatin and 5-fluorouracil. Eighty-six patients (80.4%) had WHO II-III histopathologic diagnosis. According to the AJCC 1997 staging system, 4 (3.6%), 3 (2.7%), 33 (30.8%) and 67 (62%) patients were in stages I, II, III and IV, respectively. With a median follow-up of 12 months, the 2-year overall and disease-free survival rates were 35% and 21%, respectively. According to the multivariate analysis for overall survival, patients under 40 years had a better prognosis (p=0.041). Node stage and stage of disease were significant prognostic factors (p=0.0001). On multivariate analysis for disease-free survival, age and node stage were significant prognostic factors. The patients who received more than 60Gy radiation had a better prognosis (p=0.02), however; sequential adjuvant chemotherapy had no impact on survival and response (p=0.6). Our experience confirmed earlier reports showing poor outcomes for locoregionally advanced nasopharyngeal carcinomas. This study failed to demonstrate improvement in the outcome regarding overall and disease-free survival by adding sequential adjuvant chemotherapy after radiotherapy for patients with advanced NPC.

Purpose. - To report characteristics and outcome of breast cancer after irradiation for Hodgkin lymphoma with special focus on breast conservation surgery. Patients and methods. - Medical records of 72 women who developed either ductal carcinoma in situ or stage I-III invasive carcinoma of the breast after Hodgkin lymphoma between 1978 and 2009 were retrospectively reviewed. Results. - Median age at Hodgkin lymphoma diagnosis was 23 years old. Median total dose received by the mediastinum was 40 Gy, mostly by a mantle field technique. Breast cancer occurred after a median time interval of 21 years. Ductal invasive carcinoma and ductal carcinoma in situ represented respectively 71% and 19% of the cases. Locoregional treatment for breast cancer consisted of mastectomy with or without radiotherapy in 39 patients and of lumpectomy with or without adjuvant radiotherapy in 32 patients. The isocentric lateral decubitus radiation technique was used in 17 patients after breast conserving surgery (57%). With a median follow-up of 7 years, 5-year overall survival rate and locoregional control rate were respectively 74.5% and 82% for invasive carcinoma and 100% and 92% for in situ carcinoma. Thirteen patients died of progressive breast cancer and contralateral breast cancer was diagnosed in ten patients (14%). Conclusions. - Breast conserving treatment can be an option for breast cancers that occur after Hodgkin lymphoma despite prior thoracic irradiation. It should consist of lumpectomy and adjuvant breast radiotherapy with use of adequate techniques, such as the lateral decubitus isocentric position. (authors)

A 3-yr-old male panther chameleon (Furcifer pardalis) presented with bilateral raised crusted skin lesions along the lateral body wall that were found to be carcinoma in situ and squamous cell carcinoma. Similar lesions later developed on the caudal body wall and tail. A subcutaneous implantable carboplatin bead was placed in the first squamous cell carcinoma lesion identified. Additional new lesions sampled were also found to be squamous cell carcinomas, and viral polymerase chain reaction was negative for papillomaviruses and herpesviruses. Significant skin loss would have resulted from excision of all the lesions, so treatment with only carboplatin beads was used. No adverse effects were observed. Lesions not excised that were treated with beads decreased in size. This is the first description of cutaneous squamous cell carcinoma and treatment with carboplatin implantable beads in a panther chameleon.

Purpose: The present study reviews the experience in treatment of 447 patients with nasopharyngeal carcinomas, analyzing patient, tumor and treatment characteristics determining outcome. Materials and methods: There were 322 males and 125 females, their ages ranging from 7 to 85 years (median, 45 years). Two-hundred and seventy-two patients had World Health Organization (WHO) type 3 carcinomas, 123 patients had T4 tumors and 320 patients had metastatic cervical lymph nodes. Three-hundred and eight patients were treated with radiation therapy alone and 139 patients with chemotherapy in combination with radiation therapy. Cumulative radiation dose to primary tumor ranged from 50 to 76 Gy (median, 70 Gy) and radiation dose to metastatic cervical lymph nodes ranged from 46 to 74 Gy (median, 66 Gy). Results: Follow-up ranged from 0.1 to 19.5 years (mean, 7.6 years). Local complete response was achieved in 357 patients. In multivariate analysis, T-classification, cumulative radiation dose to primary tumor and treatment with chemotherapy in combination with radiation therapy predicted local response. Nodal complete response was achieved in 272 patients. In multivariate analysis, N-classification and radiation dose to metastatic cervical lymph nodes predicted nodal response. Local failure was observed in 70 patients, nodal failure in 35 patients and systemic failure in 114 patients. Overall survival, disease-free survival and disease-specific survival were 33, 32 and 37%, respectively, at 10 years. In multivariate analysis, age, T-classification, N-classification, radiation dose and treatment with chemotherapy in combination with radiation therapy predicted overall survival whereas T-classification, N-classification, radiation dose and treatment with chemotherapy in combination with radiation therapy predicted both disease-free survival and disease-specific survival. Conclusions: Radiation therapy alone appears to be an adequate and viable treatment for patients with early

Electrochemotherapy provides non-thermal ablation of cutaneous as well as deep seated tumors. Based on positive results of the treatment of colorectal liver metastases, we conducted a prospective pilot study on hepatocellular carcinomas with the aim of testing the feasibility, safety and effectiveness of electrochemotherapy. Electrochemotherapy with bleomycin was performed on 17 hepatocellular carcinomas in 10 patients using a previously established protocol. The procedure was performed during open surgery and the patients were followed for median 20.5 months. Electrochemotherapy was feasible for all 17 lesions, and no treatment-related adverse events or major post-operative complications were observed. The median size of the treated lesions was 24 mm (range 8-41 mm), located either centrally, i.e., near the major hepatic vessels, or peripherally. The complete response rate at 3-6 months was 80% per patient and 88% per treated lesion. Electrochemotherapy of hepatocellular carcinoma proved to be a feasible and safe treatment in all 10 patients included in this study. To evaluate the effectiveness of this method, longer observation period is needed; however the results at medium observation time of 20.5 months after treatment are encouraging, in 15 out of 17 lesions complete response was obtained. Electrochemotherapy is predominantly applicable in patients with impaired liver function due to liver cirrhosis and/or with lesions where a high-risk operation is needed to achieve curative intent, given the intra/perioperative risk for high morbidity and mortality.

Asakawa, H; Otawa, H; Yamada, S [Miyagi Prefectural Adult Disease Center, Natori (Japan)

1979-01-01

Thirty cases with recurrent gastric carcinoma were treated with a combination of high energy x-ray and some anti-cancer drugs at Miyagi Seijinbyo Center between 1967 and 1977. Twenty three cases of them tolerated well such treatment; the irradiated dose was more than 4000 rad without any serious complication. The response of recurrent tumor to irradiation was marked in 11 lesions of 21 local recurrences and 4 metastases of the lymph node. The survival rates of those irradiated more than 4000 rad were 22% at one year, 15% at two years and 5% at three years. The median survival month was 6,9 months. These rates obtained in a combined radiation therapy seemed to be well matched for those reported by other authors in a surgical management of recurrent gastric carcinoma. As a conclusion, it was suggested that a combined radiation therapy with some anticancer drugs should be an effective procedure to prolong the life of a patient of recurrent gastric carcinoma.

The Changing Treatment Landscape for Metastatic Urothelial Carcinoma.

Flaig, Thomas W

2018-05-01

Urothelial carcinoma is the predominant histologic type of bladder cancer. After 30 years of minimal progress in the treatment of advanced-stage disease, recent advances in the genomic characterization of urothelial cancer and breakthroughs in bladder cancer therapeutics have rejuvenated the field. Nivolumab, pembrolizumab, atezolizumab, durvalumab, and avelumab are among the exciting recent novel therapeutic advances gaining approvals by the FDA for treatment of advanced-stage urothelial carcinoma. Yet the challenge for clinicians is to determine the optimal choice of agents as first-line or second-line therapy and which offers the best chance for overall survival for the individual patient in this rapidly changing field.

Eriko Fujimoto

2018-05-01

Full Text Available Pulmonary pleomorphic carcinoma (PPC has a poor prognosis due to the poor results of treatment with systemic chemotherapy. We report the case of a 73-year-old woman with PPC who showed a favorable response to nivolumab. As first-line treatment for postoperative recurrence, she received carboplatin and nanoparticle albumin-bound paclitaxel. However, 12 months later, a new metastatic lymph node appeared. Nivolumab was administered as second-line treatment, and the patient showed a favorable prolonged response. The effects of treatment of PPC with nivolumab seem promising. The results of a future prospective study are expected to identify indicators for the treatment of PPC.

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%.

To evaluate the long-term follow-up results of percutaneous ethanol injection (PEI) for the treatment of hepatocellular carcinoma (HCC) in Korea. Sixty-eight nodular HCCs initially detected in 64 patients, were subjected to US-guided PEI as a first-line treatment. Long-term survival rates, local tumor progression rates, and complications were evaluated, as were the influences of tumor size and Child-Pugh class on these variables. No major complications occurred. The overall survival rates of the 64 patients at three and five years were 71% and 39%, and their cancer-free survival rates were 22% and 15%, respectively. The overall survival rate of patients with a small HCC (≤ 2 cm) was significantly higher (p = 0.014) than that of patients with a medium-sized HCC (≤ 2 cm). The overall survival rate of patients with Child- Pugh class A was significantly higher (p = 0.049) than that of patients with Child- Pugh class B. Of 59 cases with no residual tumor, local tumor progression was observed in ablation zones in 18, and this was not found to be significantly influenced by tumor size or Child-Pugh class. The results of our investigation of the long-term survival rates of PEI in HCC patients in Korea (a hepatitis B virus-endemic area) were consistent with those reported previously in hepatitis C endemic areas. Patients with a smaller tumor or a better liver function exhibited superior survival rates

Adenovirus mediated homozygous endometrial epithelial Pten deletion results in aggressive endometrial carcinoma

Energy Technology Data Exchange (ETDEWEB)

Pten is the most frequently mutated gene in uterine endometriod carcinoma (UEC) and its precursor complex atypical hyperplasia (CAH). Because the mutation frequency is similar in CAH and UEC, Pten mutations are thought to occur relatively early in endometrial tumorigenesis. Previous work from our laboratory using the Pten{sup +/-} mouse model has demonstrated somatic inactivation of the wild type allele of Pten in both CAH and UEC. In the present study, we injected adenoviruses expressing Cre into the uterine lumen of adult Pten floxed mice in an attempt to somatically delete both alleles of Pten specifically in the endometrium. Our results demonstrate that biallelic inactivation of Pten results in an increased incidence of carcinoma as compared to the Pten{sup +/-} mouse model. In addition, the carcinomas were more aggressive with extension beyond the uterus into adjacent tissues and were associated with decreased expression of nuclear ER{alpha} as compared to associated CAH. Primary cultures of epithelial and stromal cells were prepared from uteri of Pten floxed mice and Pten was deleted in vitro using Cre expressing adenovirus. Pten deletion was evident in both the epithelial and stromal cells and the treatment of the primary cultures with estrogen had different effects on Akt activation as well as Cyclin D3 expression in the two purified components. This study demonstrates that somatic biallelic inactivation of Pten in endometrial epithelium in vivo results in an increased incidence and aggressiveness of endometrial carcinoma compared to mice carrying a germline deletion of one allele and provides an important in vivo and in vitro model system for understanding the genetic underpinnings of endometrial carcinoma.

The results of the treatment of 28 patients with an anaplastic thyroid gland carcinoma are investigated, to see whether an optimal therapy is indicated. The execution of an operation before radiotherapy does not appear to improve the prognosis (statistically this conclusion is not wholly justified). The presence of metastases at the beginning of the therapy gave rise to a worse prognosis than the absence of metastases. The combination treatment of chemotherapy and either surgery or radiotherapy was only applied to two patients so no conclusions can be made about its benefit. (C.F.)

Objective: To investigate the application of virtual reality technology in the preoperative evaluation of complex head and neck carcinoma and he value of virtual reality technology in surgical treatment of head and neck carcinoma. Methods: The image data of eight patients with complex head and neck carcinoma treated from December 2016 to May 2017 was acquired. The data were put into virtual reality system to built the three-dimensional anatomical model of carcinoma and to created the surgical scene. The process of surgery was stimulated by recognizing the relationship between tumor and surrounding important structures. Finally all patients were treated with surgery. And two typical cases were reported. Results: With the help of virtual reality, surgeons could adequately assess the condition of carcinoma and the security of operation and ensured the safety of operations. Conclusions: Virtual reality can provide the surgeons with the sensory experience in virtual surgery scenes and achieve the man-computer cooperation and stereoscopic assessment, which will ensure the safety of surgery. Virtual reality has a huge impact on guiding the traditional surgical procedure of head and neck carcinoma.

mTOR inhibitors in the treatment of advanced renal cell carcinoma

Renal Cell Carcinoma (RCC) accounts for approximately 4 % of all malignancies. Much is known about the pathogenesis of RCC because of studies examining its close relationship with dysfunction of the Von Hippel-Lindau gene (VHL) and hypoxia inducible factor (HIF). Mammalian target of rapamycin (mTOR) regulates nutritional needs, cell growth, and angiogenesisi in cells by down regulating or up regulating a variety of proteins including HIF. Until 2005, only a single agent high dose interleukin 2 was approved by Food and Drug Administration (FDA) for treatment of advanced renal cell carcinoma. More recently thanks to better knowledge in the field of molecular biology new treatment options appeared. Sunitinib and bevacizumab are currently considered to be treatment of first choice for patients in good and intermediate prognostic group and sorafenib is preferred second line treatment in the same patient population pretreated with cytokines after disease progression. Temsirolimus and everolimus, rapamycin analouges, have recently been tested in III trials in first and second line treatment in patients with advanced metastatic clear cell renal cell carcinoma.

Distant metastases in differentiated thyroid carcinoma: diagnosis and treatment

International Nuclear Information System (INIS)

Schmidt, A.; Cross, G.; Pitoia, F.

2017-01-01

Distant metastases occur in less than 10% of patients with differentiated thyroid carcinoma. In these patients, overall survival at 10 years is considerably reduced. Whereas cure is the initial goal of treatment, stabilisation of the disease and management of symptoms have become the primary objective in many patients with persistent radio-iodine refractory progressive disease. In the last decade, several targeted therapies have shown encouraging results in patients with advanced disease. The objective of this review is to describe the characteristics, diagnosis, overall survival, and the local and systemic available treatments for patients with distant metastases from differentiated thyroid cancer.

Hepatocellular carcinoma (HCC) is frequently diagnosed at advanced stages and has a high mortality rate. With improved survival of patients with cirrhotic liver disease and increased prevalence of chronic hepatitis C viral infections, a rise in the number of HCC cases is being reported worldwide. Early diagnosis and treatment can significantly improve the prognosis of patients with HCC. Although surgical resection is an important potentially curative therapy for liver tumors, in appropriately selected patients, liver transplantation has been shown to achieve excellent survival rates for a solid tumor. Locally ablative and locoregional therapies in the form of percutaneous ethanol injection, radiofrequency ablation, transcatheter arterial chemoembolization and transcatheter arterial radioembolization (TheraSphere) are viable options in patients with unresectable HCC. Unfortunately, the role of systemic therapy has been very limited in the treatment of these patients. Novel treatment options based on an improved understanding of the molecular pathogenesis of HCC are being explored. These targeted molecular therapies are aimed at growth factors and their receptors, intracellular signal transduction and cell cycle control. A substantial improvement in outcomes of intermediate and advanced stage HCC is expected with the advent of these targeted therapies, used in combination with surgical or locoregional therapies. Recent positive results from a large Phase III study of the receptor tyrosine kinase inhibitor, sorafenib, hold great promise in the treatment of HCC.

Ultrastructural changes of human esophageal carcinoma induced by preoperative treatments with bleomycin and/or radiation

In the present study, 44 cases of esophageal carcinoma were electron-microscopically examined. Nuclear bodies of various types observed in carcinoma cells or in normal mucosa of the esophagus treated by bleomycin and radiation, single or combined (BLM/R), were classified into seven types. Types A and B were observed in carcinoma cells of both conditions of untreated or treated with BLM/R. Types C, D and E were specific findings in squamous carcinoma cells after BLM/R treatment. Types F and G were considered to be far advanced in terms of other nuclear bodies and were observed in strongly affected carcinoma cells. These nucleolar changes were considered to be specific alterations induced by BLM in esophageal carcinoma cells. The appearance of various nuclear bodies and a series of nucleolar segregation after BLM/R treatments were confirmed as well in metastatic lesions of abdominal lymph nodes that may be affected only with minimal or disregardable scattered radiation, if any, giving no sifnificant influence to cell activity. This fact has suggested that types C, D and E nuclear bodies and nucleolar segregation are changes specific to BLM/R treatments, some solely to BLM. Other nuclear changes consisted in the appearance of fibrillar structures of three different types that were considered to have been produced by disturbed ribosomal activity in the nuclei. On the basis of results in the present study, BLM apparently showed serious evidence of remarkable influences or effects, although not constantly and generally available, on certain squamous carcinoma cells of the esophagus. Some of the evidence was represented by nucleolar segregation and characteristic nuclear bodies of different types, particularly of types C, D and E.

The purpose of this study is to evaluate the therapeutic efficacy of intra-arterial infusion of Cis-diamminedichloroplatinum (C-DDP) for the treatment of hepatocellular carcinomas with widespread involvement. We retrospectively analyzed 22 patients who between July 1994 and June 1996 had undergone intra-arterial c-DDP infusion therapy for the treatment of hepatocellular carcinomas with widespread involvement. The hepatomas involved both lobes in ten, portal venous obstructions in fourteen, arterio-portal shunts in nine, and arterio-venous shunts in two. Proper hepatic artery was selected for infusion of 100 mg/BSA of C-DDP. The same procedure was repeated every 3 to 4 weeks, and the total number of infusions was 65. On the basis of WHO criteria, response was classified as complete remission, partial remission, stable, or progression of the disease. Six-month and one-year survival rates were estimated, and adverse reactions were evaluated. Although the response rate is not high, intra-arterial C-DDP infusion therapy can be used as an alternative treatment for hepatocellular carcinomas with widespread involvement; adverse reactions are tolerable.

1999-01-01

This article presents a review of the literature regarding the use of transcatheter arterial chemoembolization (TACE) in the treatment of hepatocellular carcinoma (HCC). There have been two different approaches to the treatment: (a) percutaneous tumor ablation methods which can be divided into injectable and thermal methods; percutaneous ethanol injection (PEI) is the most widely used method, and (b) TACE. PEI is the treatment of choice for single HCCs smaller or equal to 3 cm in size. For patients with large HCCs combined TACE and PEI is probably the most effective nonsurgical treatment. In the presence of multiple HCC nodules, TACE remains the treatment of choice

The efficacy of hypofractionated radiation protocol for feline facial squamous cell carcinoma was evaluated. Hypofractionated radiation therapy was applied to five cats showing single or multiple facial squamous cell carcinomas, in a total of ten histologically confirmed neoplastic lesions. Of the lesions, two were staged as T{sub 1}, four as T{sub 2}, two as T{sub 3}, and two as T{sub 4}. The animals were submitted to four radiation fractions from 7.6 to 10 grays each, with one week intervals. The equipment was a linear accelerator with electrons beam. The cats were evaluated weekly during the treatment and 30 and 60 days after the end of the radiation therapy. In this study, 40% of the lesions had complete remission, 40% partial remission, and 20% did not respond to the treatment. Response rates were lower as compared to other protocols previously used. However, hypofractionated radiation protocol was considered safe for feline facial squamous cell carcinoma. (author)

Carcinoma of the endometrium-prognostic factors and treatment decisions

1997-01-01

PURPOSE: Carcinoma of the endometrium is the most common gynecological malignancy in the U.S. As the treatment for endometrial cancer has evolved, FIGO has modified the staging three times over the past 25 years This course will review current staging, prognostic factors, treatment options, rationale and management strategies for patients with endometrial carcinoma. The data regarding local control and survival, and the ongoing clinical trials and controversies will be discussed in depth. MATERIALS AND METHODS: Despite the continued controversy regarding the true contribution of extensive surgical staging, the standard treatment for operable patients is total abdominal hysterectomy-bilateral salpingoopherectomy with regional lymph node staging. Various combinations of surgery and radiation have been used in the past, but the precise role of radiation as an adjuvant treatment is not well defined due to lack of well conducted randomized trials. With better knowledge and understanding of the natural history of the disease and significance of prognostic factors, three different risk groups have been identified; low risk, intermediate risk, high risk. Postoperative radiation has been shown to decrease local failures and improve survival in the majority of the intermediate risk group and high risk group of patients. Considerable experience has been accumulated in the use of High Dose Rate fractionated intravaginal treatment, and it probably has a very broad application in optimizing local control, with minimal morbidity. A stage-specific treatment algorithm, including critical pathways for the management of early and advanced endometrial cancer will be presented. RESULTS: As is evident from the long-term published data, the results of combined surgery and radiation treatment have been very satisfactory with minimal complications. CONCLUSION: A thorough assessment of the clinical and surgicopatho-logic prognostic parameters, in the context of the natural history of the

Thyroid cancer is the endocrine tumor that bears the highest incidence with 33 550 new cases per year. It bears an excellent prognosis with a mortality of 1530 patients per year (Jemal et al.; 2007). We have been treating patients with thyroid carcinoma during many years without many innovations. Recently, we have assisted to the development of new agents for the treatment of this disease with unexpected good results. Here we present a review with the old and new methods for the treatment of this disease. PMID:21048836

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

Differentiated thyroid carcinoma includes 2 different tumor types, papillary (PC) and follicular carcinoma (FC), and although similar, their prognosis is different. FC is uncommon, and this has led to it often being analyzed together with PC, and therefore the true reality of this tumor is difficult to know. As a result, the diagnostic and therapeutic management and the prognostic factors in differentiated carcinoma are more predictive of PC than FC. In this review we analyze the current state of many of the therapeutic aspects of this pathology. The best surgical technique and the usefulness of associated lymphadenectomy is also analyzed. Regarding post-surgical ablation with 131I, the indications, doses and usefulness are discussed. For the remaining therapies we analyze the few indications for radiotherapy and chemotherapy, and of new drugs such as tyrosine kinase inhibitors. Copyright © 2015 AEC.

Forty-seven cases of carcinoma of the mesopharynx, treated from 1973 to 1981 at Gunma Cancer Center, were evaluated. The following results were obtained, 1) According to histopathologic diagnosis, 37 were well-differentiated squamous cell carcinoma and other cases were poorly differentiated squamous cell carcinoma. 2) Classification of the site of the disease showed the most frequent site was lateral wall type (31 cases, 65.9 per cent) followed by anterior wall (9 cases), superior wall (5 cases), and posterior wall types (2 cases). 3) According to TN classification, there were 1 case in T1, 14 cases in T2, 24 cases in T3, and 7 cases in T4, N distribution revealed 27 cases N0, 20 cases N1, N2 and N3. 4) The most common treatment was intraarterial chemotherapy using 5-FU combined with external irradiation (15 cases, 31.9 per cent), external irradiation alone (14 cases, 29.7 per cent), external irradiation with Radium (8 cases, 17.0 per cent), and combined with cryosurgery 5 cases, 10.6 per cent). The five-year cumulative survival rate was 35.3 per cent. The lesion of mesopharyngeal carcinoma takes verious forms, so the treatment policy cannot be a standard one. Thus multi-disciplinary treatment should be applied for this disease. (author)

Objective: To discuss the clinical effect and safety of urgent embolization with arterial catheterization in the treatment of serious epistaxis in patients with nasopharyngeal carcinoma after radiotherapy. Methods: Fifteen patients with nasopharyngeal carcinoma occurred serious epistaxis after radiotherapy. Because of failure to respond to the treatment of nasal packing and medication, embolization of the bleeding arteries with gelfoam or steel coils was carried out within 1-4 hours after the bleeding. The target arteries were judged by the internal and external carotid angiographic findings. Results: The embolization procedure was successfully completed, in all of 15 patients within 1.5 hours with the technical successful rate of 100%. The bleeding ceased in all 15 patients with the effective rate of 100%. Mild facial palsy occurred in 2 cases, and facial pain of the affected side in one case. All above symptoms were relived and disappeared in about one week after the procedure, leaving no serious complications. Conclusion: Urgent arterial embolization is an effective, safe and simple method for controlling the serious epistaxis in nasopharyngeal carcinoma after radiotherapy. (authors)

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

Current and emerging treatment options for nasopharyngeal carcinoma

Full Text Available Daniel E Spratt, Nancy LeeDepartment of Radiation Oncology, Memorial Sloan-Kettering Cancer Center, New York, NY, USAAbstract: In this article, we focus on the current and emerging treatments in nasopharyngeal cancer (NPC. A detailed evolution of the current standard of care, and new techniques and treatment options will be reviewed. Intergroup 0099 established the role for chemoradiotherapy (chemo-RT in the treatment of nasopharyngeal carcinoma. Multiple randomized Phase III trials have shown the benefit of chemo-RT; however, none of these studies utilized modern radiotherapy (RT techniques of intensity-modulated radiation therapy (IMRT. IMRT has the ability to deliver high doses of radiation to the target structures while sparing adjacent bystander healthy tissues, and has now become the preferred RT treatment modality. Chemotherapy also has had a shifting paradigm of induction and/or adjuvant chemotherapy combined with RT alone, to the investigation with concurrent chemo-RT. New treatment options including targeted monoclonal antibodies and small molecule tyrosine kinase inhibitors are being studied in NPC. These new biologic therapies have promising in vitro activity for NPC, and emerging clinical studies are beginning to define their role. RT continues to expand its capabilities, and since IMRT and particle therapy, specifically intensity-modulated proton therapy (IMPT, has reports of impressive dosimetric efficacy in-silica. Adaptive RT is attempting to reduce toxicity while maintaining treatment efficacy, and the clinical results are still in their youth. Lastly, Epstein–Barr virus (EBV DNA has recently been studied for prediction of tumor response and its use as a biomarker is increasingly promising to aid in early detection as well as supplementing the current staging system. RT with or without chemotherapy remains the standard of care for nasopharyngeal carcinoma. Advances in RT technique, timing of chemotherapy, biologically

New strategy for treatment of carcinoma of the hilar bile duct

Koyama, K.; Tanaka, J.; Kato, S.; Asanuma, Y.

1989-01-01

Surgical treatment for carcinoma of the hilar bile duct has been a challenging problem, because the five year survival rate is less than 5 per cent and the mean survival period is 17 to 24 months even in curatively resected instances. The prognostic factors of carcinoma of the hilar bile duct are remnant carcinoma at the bile duct stump and cancerous invasion into the lymphatics, veins, perineural spaces around the intrahepatic bile duct and caudate lobe of the liver. Based on these data, a new strategy for treatment of carcinoma of the hilar bile duct has been developed and applied clinically. The strategy consists of three procedures. The first is resection of the hilar bile duct with portajejunostomy; the second, specific anticancer therapy with mitomycin C (4 milligrams) adsorbed to the activated charcoal (MMC-CH) focused on the invasion of carcinoma to the periductal lymphatics, and third, intracavitary irradiation (32 to 40 gray) by 60Co using the remote after loading system through the bile duct focused on the periductal infiltration of the carcinoma and through the inferior vena cava focused on the caudate lobe of the liver. In this article, the operative procedures and theoretic background of the specific chemotherapy and irradiation are described. Seven patients have been treated using this regimen. Follow-up study ranged from seven to 38 months. All patients are alive, and five of seven are disease-free

Objective: To evaluate treatment results and prognostic factors of 47 patients with primary urethral transitional cell carcinoma treated with post-operative adjuvant radiotherapy. Methods: From October 1998 to October 2008, 47 patients with primary urethral transitional cell carcinoma received postoperative adjuvant radiotherapy. Thirty-one patients had stage T 3 /T 4 disease, 7 had lymph node metastasis. Thirty-nine patients had G3 tumor, 13 had stump-positive. The median radiotherapy dose was 60 Gy (36-64 Gy). 81% patients (38/47) were treated with regional irradiation. Results: The median follow-up time was 21 months (6 -88 months). The follow-up rate was 92%. The median overall survival time was 35 months (5 -88 months). The 2-and 5-year overall survival rates were 57% and 49%, respectively. In univariate analysis, the median overall survival time was better in patients with stage T 1 or T 2 compared with stage T 3 or T 4 tumor (42 months vs. 19 months, χ 2 =7.28, P=0.007), with age of ≤65 years compared with >65 years (28 mouths vs 18 months,χ 2 =8.23, P =0.004). There was no significant difference in the long term survival in patients with non-radical surgery compared with radical mastectomy (21 months vs. 20 months, χ 2 = 0.90, P = 0.344). In multivariate analysis, the stage T 3 or T 4 (χ 2 = 7.89, P =0.005), >65 years old (χ 2 = 4.85, P = 0.028), renal pelvis involvement (χ 2 = 5.65, P = 0.018), and tumor located in the mid or inferior segment (χ 2 =6.08,P =0.014) were factors associated with poorer prognosis. Conclusions: Postoperative adjuvant radiotherapy can improve the efficacy of patients with locally advanced urethral transitional cell carcinoma. Advanced T stage and > 65 years age are associated with poorer prognosis. (authors)

We report a case of a mixed adenoneuroendocrine carcinoma developed in a colorectal adenocarcinoma with lymph node and liver metastases exclusively emanating from the neuroendocrine carcinoma component. The patient underwent right hemicolectomy and postoperatively received chemotherapy with cisplatin and etoposide and subsequent high-dose induction chemotherapy, followed by autologous stem cell transplantation. Following this treatment, there was a complete remission. Currently, thirty months after treatment, the patient is in unmaintained complete remission. Comparative exome sequencing of germline DNA and DNA from the two separate malignant components revealed six somatic changes in cancer consensus genes. Both components shared somatic mutations in Adenomatous polyposis coli (APC), Kirsten rat sarcoma viral oncogene homolog (KRAS), B-cell CLL/lymphoma 9 (BCL9) and Forkhead Box P1 (FOXP1) genes. Mutation in SWI/SNF related, matrix associated, actin dependent regulator of chromatin, subfamily a, member 4 (SMARCA4) was only found in the neuroendocrine carcinoma component. The finding of several identical somatic mutations in both components supports a clonal relationship between the neuroendocrine carcinoma and the adenocarcinoma. We suggest that a mutation in SMARCA4 could be responsible for the transformation of the adenocarcinoma component into the neuroendocrine phenotype.

The effect of wool hydrolysates on squamous cell carcinoma cells in vitro. Possible implications for cancer treatment.

Directory of Open Access Journals (Sweden)

Tatsiana Damps

Full Text Available Squamous cell carcinoma of the skin is the second most common cutaneous malignancy. Despite various available treatment methods and advances in noninvasive diagnostic techniques, the incidence of metastatic cutaneous squamous cell carcinoma is rising. Deficiency in effective preventive or treatment methods of transformed keratinocytes leads to necessity of searching for new anticancer agents. The present study aims to evaluate the possibility of using wool hydrolysates as such agents. Commercially available compounds such as 5-fluorouracil, ingenol mebutate, diclofenac sodium salt were also used in this study. The process of wool degradation was based on chemical pre-activation and enzymatic digestion of wool. The effect of mentioned compounds on cell viability of squamous carcinoma cell line and healthy keratinocytes was evaluated. The obtained data show a significantly stronger effect of selected wool hydrolysates compared to commercial compounds (p<0.05 on viability of cells. The wool hydrolysates decreased squamous cell carcinoma cells viability by up to 67% comparing to untreated cells. These results indicate bioactive properties of wool hydrolysates, which affect the viability of squamous carcinoma cells and decrease their number. We hypothesize that these agents may be used topically for treatment of transformed keratinocytes in actinic keratosis and invasive squamous skin cancer in humans.

Between 1969 and 1985, 73 patients with maxillary sinus cancers underwent surgical excision and postoperative radiotherapy. The clinical stage distribution by the AJC system was 3T{sub 1}, 16T{sub 2}, 32T{sub 3} and 22 T{sub 4}. Six patients had palpable lymphadenopathy at diagnosis. Surgery for the primary tumor consisted of partial or radical maxillectomy, and if disease stage indicated it, ipsilateral orbital exenteration. This was followed by radiation treatment delivered through a wedge-pair or three-field technique. All but 3 patients received 50-60 Gy in 2 Gy fractions to an isodose line defining the target volume. Elective neck irradiation (ENI) was nor routinely given. Clinically involved nodes were treated with definitive radiotherapy (5 patients) or combined treatment (1 patient). Forty-five patients had no evidence of disease at the last follow-up. The 5-year relapse-free survival for the whole group was 51 percent. The overall local control rate was 78 percent, Patients with larger tumors, particularly if they also had histological signs of nerve invasion, had a higher recurrence rate than others. The overall nodal recurrence rate without ENI was 38 percent for squamous and undifferen-tiated carcinoma, and only 5 for adenoid cystic carcinomas. Therefore, the current recommendation is to deliver elective nodal irradiation routinely to patients with squamous or undifferentiated carcinoma, except for those who have T{sub 1} lesions. Treatment complications were vision impairment, brain and bone necrosis, trismus, hearing loss, and pituitary insufficiency. The incidence of major side effects was determined by disease extent and treatment technique. Many technical refinements were introduced in order to limit the dose to normal tissues in an attempt to reduce the complication rate. To what extent such practice influences the outcome will be determined from subsequent analysis. (author). 23 refs.; 2 figs.; 5 tabs.

High dose radiation therapy given as a single fraction to the upper and lower halves of the body gives effective palliation for metastatic solid tumours. This treatment modality appears to be particularly effective in tumours which may have a slow doubling time such as carcinoma of the prostate. Fifty-two patients with metastatic carcinoma of the prostate involving the skeletal system have received half-body irradiation (8 MeV X-rays at a dose rate of about 100 cGy/min). All had prior treatment with additive hormones or orchiectomy and the majority had received localised irradiation and/or chemotherapy. Significant immediate pain relief was achieved in 42 out of 52 patients (80%). This pain relief was maintained until death in 29 out of 43 patients (67%). Pain relief in responders appears to occur within 24 to 48 h of treatment. (author)

Full Text Available O carcinoma basocelular é a neoplasia mais comum da região periocular, sendo responsável por 90% dos tumores palpebrais. Sua incidência vem aumentando significativamente nos últimos anos. Embora de crescimento lento e raramente resultando em metástases, sua extensão e localização oferecem grandes dificuldades terapêuticas, quando envolve a região periocular. O tratamento cirúrgico é o de escolha para a região periocular, entretanto, novas modalidades de terapia têm sido propostas. As técnicas cirúrgicas reparadoras podem comprometer tanto a função palpebral (proteção ocular como a estética da região. Atualmente, se destaca uma nova forma de abordagem clínica, os imunomoduladores tópicos. O Imiquimode creme 5% é o principal representante dessa nova classe de medicamentos, tendo sido amplamente estudado recentemente e tendo apresentado alto índice de eficácia no tratamento do carcinoma basocelular. A presente revisão tem, portanto a finalidade de realizar uma análise sistemática da literatura relevante em busca de artigos e trabalhos que comprovem a eficácia da utilização do imiquimode 5% creme no tratamento do carcinoma basocelular periocular.The basal cell carcinoma is the most common neoplasia of the periocular region, being responsible for 90% of the eyelid malignancies.

Purpose: This study aimed to evaluate the efficacy of high-dose-rate brachytherapy (HDRB) in the primary treatment of endometrial carcinoma. The results of 12 years of experience (1981-1992) covering 280 patients (mean age 72 years) and their follow-up over 10 years (mean 55 months) are reported. Methods and Materials: Staging was based on clinical examination and fractionated curettage. There were 116 patients in clinical Stage Ia, 119 in Stage Ib, 37 in Stage II, and 8 in Stage III. HDRB was performed four to five times (8.5 Gy) with a one-channel intracavitary applicator and one to two times (7 Gy) with an intravaginal cylinder applicator. Overall and disease-specific survival, local control according to stage and histology, and late side effects were analyzed retrospectively (actuarial method). Results: At 5 years, overall survival, disease-specific survival, and local control were 52.7%, 76.6%, and 75.4% (Stage Ia: 63.9%, 84.9%, and 86.0%; Stage Ib: 47.3%, 73.3%, and 68.8%; and Stage II: 40.2%, 68.6%, and 60.5%) according to histopathologic Grade 1: 65.1%, 83.5%, and 77.7%; for Grade 2: 44.7%, 75.4%, and 75.8%; and for Grade 3: 37.7%, 63.9%, and 74.1%. Eight patients showed progressive disease, 64 developed recurrence after a median of 13 months (45 of whom had a local recurrence only, and 6 of whom had a local recurrence with distant metastases), 6 developed a lymph node recurrence only, and 7 developed distant metastases only. The calculated probability for developing a Grade III late side effect was 5.2% at 5 years. Conclusion: At Stages Ia, Ib, and II in endometrial carcinoma, HDRB is a very effective treatment modality with acceptable local control rates and disease-specific survival for patients who are not fit for surgery. During the time frame of 12 years and in 280 patients the method has proven to have a low risk of acute complications and an acceptable risk of long-term side effects

Full Text Available Saby George1, Ronald M Bukowski21University of Texas Health Sciences Center, MC-8221, Division of Hematology and Oncology, San Antonio, Texas, USA; 2CCF Lerner College of Medicine Division of Hematology and Oncology, Cleveland, Ohio, USAAbstract: The therapeutic options in metastatic renal cell carcinoma have been recently expanded by the discovery of the VHL gene, the mutation of which is associated with development of clear cell carcinoma, and overexpression of the angiogenesis pathway, resulting in a very vascular tumor. This breakthrough in science led to the development of a variety of small molecules inhibiting the VEGF-dependent angiogenic pathway, such as sunitinib and sorafenib. These agents prolong overall and progression-free survival, respectively. The result was the development of robust front-line therapies which ultimately fail and are associated with disease progression. In this setting, there existed an unmet need for developing second-line therapies for patients with refractory metastatic renal cell carcinoma (MRCC. Everolimus (RAD 001 is an oral inhibitor of the mammalian target of rapamycin (mTOR pathway. The double-blind, randomized, placebo-controlled phase III trial of everolimus (RECORD-1 conducted in MRCC patients after progression on sunitinib or sorafenib, or both, demonstrated a progression-free survival benefit favoring the study drug (4.9 months vs 1.9 months, HR 0.33, 95% CI 0.25 to 0.43, P ≤ 0 0.001. Everolimus thus established itself as a standard of care in the second-line setting for patients with MRCC who have failed treatment with VEGF receptor inhibitors.Keywords: mTOR inhibitor, mammalian target of rapamycin inhibitor, signal transduction inhibitor, renal cell carcinoma, targeted therapy

Merkel cell carcinoma, though rare, is one of the most aggressive tumors a dermatologist faces. More than a third of patients with this diagnosis die from the disease. Numerous researchers have attempted to identify clinical and pathologic predictors to guide prognosis, but their studies have produced inconsistent results. Because the incidence of Merkel cell carcinoma is low and it appears in patients of advanced age, prospective studies have not been done and no clear treatment algorithm has been developed. This review aims to provide an exhaustive, up-to-date account of Merkel cell carcinoma for the dermatologist. We describe prognostic factors and the imaging techniques that are most appropriate for evaluating disease spread. We also discuss current debates on treating Merkel cell carcinoma.

1997-01-01

Purpose. The comparative efficacy of transcatheter arterial chemoembolization (TACE) and percutaneous ethanol injection (PEI) in the treatment of hepatocellular carcinoma (HCC) was investigated. Methods. Two hundred and sixty consecutive patients were retrospectively analyzed: 156 had received between one and six chemoembolization sessions at 3-month intervals, 33 had had PEI, and the remaining 71 patients refused any treatment. The follow-up ranged from 3 to 36 months. Survival rates were statistically analyzed by life-table analysis. Results. Patients' survival was affected by the number of nodules and by the Child's and Okuda's classes; no relationship was found between survival rates and the histologic grade or vascular supply of the tumor. In the case of a single lesion of Okuda's class I, TACE was more effective than PEI. In multifocal HCC, TACE was better than no treatment in Okuda's class I and Child's class A. Conclusion. We suggest TACE as the treatment of choice in Child A or Okuda I patients with multifocal HCCs; it seems of little help in Child B-C or Okuda II-III patients

The purpose of this study was to evaluate the effectiveness of three-dimensional conformal radiotherapy and thalidomide in the treatment of advanced hepatocellular carcinoma. Between 1999 and 2003, 121 patients (mean age, 54.4±12.4 years; range, 20-81 years) with advanced hepatocellular carcinoma received three-dimensional conformal radiotherapy and thalidomide. Radiation was delivered in 1.5 Gy fractions twice daily for 5 days a week, for a total dose of 45-75 Gy. Mean treatment volume was 429.52±408.50 cm 3 (range, 26.89-2284.82 cm 3 ). Thalidomide was given concomitantly: 200 mg/day in 109 patients, 300 mg/day in 8 patients and 400 mg/day in 4 patients. Treatment responses, survival rates and factors affecting survival were analyzed. Treatment responses were observed in 61% of the patients. Liver cirrhosis (P=0.001) and tumor size (P=0.001) significantly affected the tumor responses. Overall survival at 6, 12 and 24 months was 84.8, 60.0 and 44.6%, respectively. On univariate analysis, liver cirrhosis (P=0.003), Karnofsky performance status (P=0.007), tumor size (P<0.001), portal vein tumor thrombosis (P<0.001) and alpha-fetoprotein level (P=0.003) were shown to significantly affect survival. On multivariate analysis, only thrombosis (P=0.039) and alpha-fetoprotein level (P=0.006) were shown to be factors affecting survival. Three-dimensional conformal radiotherapy with thalidomide seems to be effective in the treatment of advanced hepatocellular carcinoma. (author)

Purpose: To define patient, tumor, and treatment factors that influence the outcome of patients with FIGO Stage IIIB squamous cell carcinoma of the intact uterine cervix. Materials and Methods: The hospital and radiotherapy records of 1007 consecutive patients treated between 1960 and 1989 for FIGO Stage IIIB squamous cell carcinoma of the intact uterine cervix were reviewed retrospectively. All patients were treated with radiation therapy (RT) either with curative intent (903 patients) or to palliate symptoms (104 patients). Patients who were selected for palliative treatment usually had a combination of adverse characteristics including massive tumor with bilateral pelvic wall fixation, hydronephrosis, bulky adenopathy, pathologic evidence of extrapelvic disease, and poor performance status. 64 (7%) of 903 patients failed to complete planned curative RT either because of progressive disease, complications, or poor compliance. Of 903 patients treated with curative intent, 319 (35%) were treated with external beam radiotherapy (EBRT) alone and 586 (65%) were treated with a combination of EBRT and intracavitary irradiation (ICRT). EBRT was usually delivered using 18-25 MV photons and ICRT was administered with Fletcher-Suit-Delclos applicators. Treatment philosophies evolved during the study period with greater emphasis placed on EBRT between 1966 and 1979 (52% treated with EBRT alone) compared with the other study years (15% treated with EBRT alone). 206 patients received investigational treatments including neutrons (69 pts), hyperbaric oxygen (66 pts), concurrent chemotherapy (29 pts), or neoadjuvant chemotherapy (42 pts). 875 patients have been followed until death. Median follow up for surviving patients is 171 months with only 9 surviving patients followed for 10%, or hgb < 10 gm% before treatment or at any time during radiotherapy. DSS was significantly better for patients whose treatment included ICRT (43% vs 21%; P< 0.0001). Also, patients who received

In 1979 the Cancer Control Agency of British Columbia changed from radium to remote controlled afterloaded caesium in the treatment of carcinoma of the cervix. In 3 years prior to the change, 139 patients received radium as part of their treatment and in the 3 years after the change, 158 patients received caesium. Overall referral patterns, patient and cancer demographics, and treatment policies were stable throughout the 6-year period. Radiotherapy technique, dose, dose distribution and dose rate were comparable for both radium and caesium treated patients. The results of treatment in the two time periods showed no difference in survival, local tumour control or complications. The use of afterloading has not compromised treatment results and has allowed better nursing care for patients and protection from radiation for all staff. (author)

From 1975 to 1989 114 patients with analcanal carcinoma were treated, 81 of these with radiotherapy (RT) alone and 33 with chemoradiotherapy (CRT). 80% respectively 82% of the patients were colostomy-free at the onset of therapy. RT was given to a total dose of 60 Gy in six weeks, for CRT additional simultaneous 5-fluorouracil (500 mg/m{sup 2} days 1 to 5 and 8 to 12) and mitomycin C (5 mg/m{sup 2} days 5 and 12) was administered. 67% respectively 82% of the patients had UICC stage II to IIIB disease predominantly with G2 and G3 squamous cell carcinomas. Local control after three years was 79% for the RT group vs. 82% for the CRT group. Three-year survival rate was 68% and 71%, respectively. These differences were not signficant. Only for G1-compared to G3-tumors there is a significantly higher survival rate. Acute and late damage was slightly lower for the RT treatment group (77% and 25%) compared to the CRT group (79% and 30%). In both treatment groups there was one patient needing a permanent colostomy due to radiation induced proctitis. In conclusion, RT or CRT should be the primary form of treatment in patients with anal canal carcinoma and abdominoperineal resection should only be performed in case of local recurrence or tumor persitence. The final decision about the indications for RT or CRT can only be made with the results of a prospective randomized trial. (orig.).

Purpose: Treatment for small-cell carcinoma of the bladder is largely guided by case reports, retrospective reviews, and small prospective trials. This study aimed to study outcomes using a large population-based database. Methods: The Surveillance, Epidemiology, and End Results-Medicare database (1991-2005) was used to analyze how different treatment combinations of specific bladder surgeries, chemotherapy, and radiation affected patient outcomes. Trends in the use of these combinations over time were also analyzed. Results: A total of 533 patients were retrieved from the database. A bladder-sparing approach involving transurethral resection of the bladder tumor (TURBT) combined with chemotherapy and radiation yielded no significant difference in overall survival compared with patients undergoing at least a cystectomy (of whom over 90% received radical cystectomy) with chemotherapy (p > 0.05). The analysis of treatment trends indicated that these two general strategies for cure combined to account for fewer than 20% of patients. A majority of patients (54%) received TURBT as their only surgical treatment, and a subset analysis of these patients indicated that chemotherapy played a role in all stages of disease (p < 0.05) whereas radiation improved overall survival in regional-stage disease (p < 0.05). Conclusion: Relatively few patients with small-cell carcinoma of the bladder receive potentially curative therapies. Chemotherapy should be a major component of treatment. Cystectomy and bladder-sparing approaches represent two viable strategies and deserve further investigation to identify the patients who may benefit from organ preservation or not. In addition, the role of radiation in regional-stage disease should be investigated further, because it positively affects survival after TURBT.

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

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

Purpose : A retrospective analysis was performed to investigate the proper management of maxillary sinus carcinoma. Materials and Methods : Authors analysed 33 patients of squamous cell carcinoma of maxillary sinus treated at Chonnam University Hospital from January 1986 to December 1992. There were 24 men and 9 women with median age of 55 years. According to AJCC TNM system of 1988, a patient of T2, 10 patients of T3 and 22 patients of T4 were available, respectively. Cervical lymph node metastases was observed in 5 patients(N1;4/33, N2b;1/33). Patients were classified as 3 groups according to management method. The first group, named as 'FAR' (16 patients), was consisted of preoperative intra-arterial chemotherapy with 5-fluorouracil(5-FU;mean of total dosage;3078mg) through the superficial temporal artery with concurrent radiation(mean dose delivered;3433cGy, daily 180-200cGy) and vitamin A(50,000 IU daily), and followed by total maxillectomy and postoperative radiation therapy(mean dose;2351cGy). The second group, named as 'SR'(7 patients), was consisted of total maxillectomy followed by postoperative radiation therapy(mean dose 5920 cGy). Her third group, named as 'R'(6 patients), was treated with radiation alone(mean dose;7164cGy). Kaplan-Meier product limit method was used for survival analysis and Mantel-Cox test was performed for significance of survival difference between two groups. Results : Local recurrence free survival rate in the end of 2 year was 100%, 5-% and 0% in FAR, SR and R group, respectively. Disease free survival rate in 2 years was 88.9%, 40% and 50% in Far, SR and R group, respectively. There were statistically significant difference between FAR and SR or FAR and R group in their local recurrence free, disease free and overall survival rates. But difference of each survival rate between SR and R group was not significant. Conclusion : In this study FAR group revealed better results that SR or R group. In the

Fifteen patients with advanced or recurrent squamous-cell carcinoma of the cervix, vulva, vagina, and urethra were treated with simultaneous combination chemotherapy (5-fluorouracil infusion and mitomycin C) and radiotherapy (3,000 rad for a period of three weeks). Three to four weeks after completion of radiotherapy, 13 of 15 patients achieved partial or complete tumor shrinkage. Nine of 15 patients are alive, eight of whom (at a median follow-up time of 24 months) have no evidence of disease. The longest survival time was 45 + months. There was minimal toxicity associated with this therapy. The results of this pilot study suggest that the simultaneous administration of radiation and chemotherapy is an effective method of treatment of advanced female genital tract carcinoma

Full text: Aim: Cell membrane-specific somatostatin receptors are usually expressed by neuroendocrine tumors. Radiolabelled receptor-binding somatostatin analogues target tissues expressing these receptors and can be used for visualization and treatment. After the localization of tumors bearing somatostatin receptors with 111In or 99mTc labeled somatostatin analogues, in the case of high tumor uptake related to non target tissues, different radioisotopes have been used for their treatment. Thus, application of high doses of 111In- DTPA-octreotide had an impact on improvement of the clinical symptoms, without significant reduction of the tumor mass. However, 90Y somatostatin analogues (DOTA TOC, lanreotide) may be more effective for reduction of the tissue of the larger tumors while 177Lu labeled ones may be applied in smaller tumors. Combination of both of them seems to be the most effective therapy, particularly in tumors bearing both small and large lesions. The aim of this work is presentation of the preliminary results of the therapy of NETs with another octreotide analogue, 90Y DOTA TATE, which so far has been proved to have high therapeutic potential when labeled with 177Lu. Patients and methods: We investigated 7 patients with neuroendocrine tumors (two patients had neuroendocrine pancreatic carcinomas with liver metastases (one of them had metastases in peritoneal lymph nodes), one patient with operated (resected) bronchial carcinoid and liver metastases, three patients with neuroendocrine carcinomas of unknown origin and hepatic metastases (one with skeletal metastases) and one with pancreatic gastrinoma without metastases (surgery was impossible to perform). In all of them, together with other laboratory analyses and imaging methods, scintigraphy with somatostatin analogues was performed (in 3 with 111In Octreoscan and in the other 4 with 99mTc HYNIC TOC) and high tumor uptake was observed. The therapy was performed with 2- 4,5 GBq 90Y DOTA TATE per

Full Text Available The basal cell carcinoma is the most common skin cancer but the giant vegetating basal cell carcinoma reaches less than 0.5 % of all basal cell carcinoma types. The Giant BCC, defined as a lesion with more than 5 cm at its largest diameter, is a rare form of BCC and commonly occurs on the trunk. This patient, male, 42 years old presents a Giant Basal Cell Carcinoma which reaches 180 cm2 on the right shoulder and was negligent in looking for treatment. Surgical treatment was performed and no signs of dissemination or local recurrence have been detected after follow up of five years.O carcinoma basocelular é o tipo mais comum de câncer de pele, mas o carcinoma basocelular gigante vegetante não atinge 0,5% de todos os tipos de carcinomas basocelulares.

The Purpose of this study was to evaluate retrospectively the management and prognosis of Merkel cell carcinoma of the eyelid in Japanese patients. Cases diagnosed as Merkel cell carcinoma of the eyelid from January 1993 to February 2005 in 111 institutions in Japan were included in this retrospective study. Management and prognosis were evaluated. The total number of cases enrolled was 21 (5 male and 16 female patients). Excision of the tumor was carried out in 18 cases. Two cases were treated with either irradiation or local injection of interferon after biopsy of the tumor. After initial treatment, there were recurrences in 3 cases; local recurrence in one case and nodal metastasis in two cases. No patient died because of Merkel cell carcinoma of the eyelid. Excision with wide surgical margins with irradiation is recommended as the first choice of treatment for Merkel cell carcinoma of the eyelid. Because the number of patients was only 21 and the duration of observation was short, further investigation is necessary to determine the optimal management and more accurate prognosis for Merkel cell carcinoma.

Sklaroff, R B; Yagoda, A

1980-01-15

Eight patients with epidermoid carcinoma of the penis received methotrexate, five with high-dose methotrexate, 250--1500 mg/m2 with citrovorum rescue Q 2--4 weeks, and three with low-dose methotrexate, 0.5--3.0 mg/kg weekly. Three (38%) patients achieved a complete or partial remission which persisted for 11, 3 and 2 months, respectively. Methotrexate appears to be an active agent in the treatment of advanced penile cancer.

Treatment recommendations in patients diagnosed with high-risk cutaneous squamous cell carcinoma

International Nuclear Information System (INIS)

Veness, M.J.

Non-melanoma cutaneous cancers occur at an epidemic rate in Australia. With an ageing population, more Australians will develop these cancers and at an increasing rate. In the majority of cases local treatment is highly curative. However, a subset of the population will be diagnosed with a high-risk cutaneous squamous cell carcinoma. These can be defined as patients at risk of having subclinical metastases to regional lymph nodes based on unfavourable primary lesion features (including inadequately excised and recurrent lesions), patients with metastatic squamous cell carcinoma to regional lymph nodes, and squamous cell carcinoma in immunosuppressed patients. The mortality and morbidity associated with high-risk cutaneous squamous cell carcinoma is usually as a consequence of uncontrolled metastatic nodal disease and, to a lesser extent, distant metastases. Radiotherapy has an essential role in treating these patients and in many cases the addition of adjuvant radiotherapy may be life saving. It is therefore important that all clinicians treating skin cancers have an understanding and awareness of the optimal approach to these patients. The aim of this article is to present treatment recommendations based on an overview of the current published literature. Copyright (2005) Blackwell Science Pty Ltd

Radiation retinopathy following treatment of posterior nasal space carcinoma

Thompson, G.M.; Migdal, C.S.; Whittle, R.J.M.

1983-01-01

Posterior nasal space carcinoma has a high mortality and most patents are treated with radiotherapy. Radiation retinopathy was encountered in 7 out of 10 survivors included in this study. Five of the affected patients lost vision as a result of the retinopathy. One patient required laser photocoagulation and responded well to this treatment. There was a variation in the severity of the retinopathy among the patients studied despite the fact that all patients received a similar dose of radiotherapy. We suspect that previously unrecognised factors in the planning of radiotherapy fields may explain this difference. (author)

Vismodegib is a first-in-class agent targeting the hedgehog signaling pathway for treatment of patients with locally advanced basal cell carcinoma (BCC) and metastatic BCC. There have been concerns about the development of squamous cell carcinoma (SCC) in patients treated with this drug. We sought to determine whether treatment with vismodegib is associated with an increase in the risk of cutaneous SCC. In this retrospective cohort study, patients treated with vismodegib as part of phase I and II clinical studies were compared with participants from the University of California, San Francisco, Nonmelanoma Skin Cancer Cohort who received standard therapy for primary BCC. In total, 1675 patients were included in the analysis, and the development of SCC after vismodegib exposure was assessed. The use of vismodegib was not associated with an increased risk of subsequent development of SCC (adjusted hazard ratio, 0.57; 95% confidence interval, 0.28-1.16). Covariates including age, sex, history of previous nonmelanoma skin cancer, and number of visits per year were significantly associated with the development of SCC. A limitation of the study was that a historic control cohort was used as a comparator. Vismodegib was not associated with an increased risk of subsequent SCC when compared with standard surgical treatment of BCC. Copyright © 2017 American Academy of Dermatology, Inc.

This study aimed to evaluate the antitumor activity of platinum nanoparticles compared with cis-platin both in vitro and in vivo in the treatment of hepatocellular carcinoma induced in rats. The treatment efficacy of platinum nanoparticles was evaluated by measuring antioxidant activities against oxidative stress caused by diethylnitrosamine in liver tissue. The measurements included reduced glutathione content and superoxide dismutase activity, as well as malondialdehyde level. Liver function tests were also determined, in addition to the evaluation of serum alpha-fetoprotein, caspase-3, and cytochrome c in liver tissue. Total RNA extraction from liver tissue samples was also done for the relative quantification of B-cell lymphoma 2, matrix metallopeptidase 9, and tumor protein p53 genes. Histopathological examination was also performed for liver tissue. Results showed that platinum nanoparticles are more potent than cis-platin in treatment of hepatocellular carcinoma induced by diethylnitrosamine in rats as it ameliorated the investigated parameters toward normal control animals. These findings were well appreciated with histopathological studies of diethylnitrosamine group treated with platinum nanoparticles, suggesting that platinum nanoparticles can serve as a good therapeutic agent for the treatment of hepatocellular carcinoma which should attract further studies.

Getting the right balance in treatment of ductal carcinoma in situ (DCIS

Full Text Available As a result of mammographic detection, ductal carcinoma in situ (DCIS is an increasing problem in breast clinics. Both histopathology and molecular profiling can identify subtypes likely to progress to invasive disease, but there is no subgroup with a zero likelihood of subsequent invasion. In patients with low/intermediate grade DCIS, if breast irradiation is not being carried out after free margins have been achieved the patient should be aware of the risks of withholding and the benefits and morbidity of adjuvant radiotherapy. Either tamoxifen or an aromatase inhibitor may be of value in those with low/intermediate ER+ve disease if radiotherapy is being withheld. For those patients with extensive or multicentric DCIS, mastectomy is the appropriate treatment. This is best combined with sentinel node biopsy and all such cases should be offered immediate reconstruction.----------------------------Cite this article as:Fentiman IS.

To evaluate the surgical diagnosis and treatment of primary hyperthyroidism complicated with occult thyroid carcinoma. Data of 51 cases of primary hyperthyroidism complicated with occult thyroid carcinoma admitted during January 2004 to November 2014 were analyzed retrospectively. The incidence of occult thyroid carcinoma was 5.03% in hyperthyroidism,and 47 cases (92.16%) were female. The preoperative diagnosis of all these 51 cases was primary hyperthyroidism and 11 cases were diagnosed thyroid carcinoma at the same time;25 cases were diagnosed thyroid carcinoma by frozen section and the remaining 26 cases were diagnosed by postoperative pathology. Finally,26 cases underwent subtotal thyroidectomy,4 cases underwent total thyroidectomy, and 21 cases underwent total thyroidectomy with lymphadenectomy. The tumor size ranged from 0.1 to 1.0 cm [mean:(0.63 ± 0.35) cm]. The lesions were less than or equal to 0.5 cm in 28 cases (54.9%). The follow-up lasted from 1 to 121 months [mean:(28.6 ± 22.7)months] in 43 patients,and all of them survived. Primary hyperthyroidism complicated with occult thyroid carcinoma is commonly found in female patients. Preoperative diagnosis is difficult. Ultrasound is the major examining method. Frozen section can increase the detection rate. The postoperative prognosis of hyperthyroidism complicated with occult thyroid carcinoma is satisfactory.

Radiation with concomitant infusion chemotherapy has proved more effective in treating several epithelial malignancies than radiation alone. Hyperfractionated radiation was combined with concomitant infusion cis-platinum chemotherapy in an attempt to obtain still better control rates. This paper presents the early results of a pilot study using this combination in the treatment of advanced and recurrent carcinoma of the paranasal sinuses as well as a case that showed response of large fixed cervical nodes having metastasized from a previously treated carcinoma of the maxillary antrum

Full text: The method of dynamic control (monitoring) of the treatment efficiency of the patients with rectal carcinoma was developed. Data of dynamic examination (every 10 days) of 174 patients with rectal carcinoma received a specific treatment at the clinic of NOSC of Uzbekistan (Tashkent) were presented. Complex examination of the patients included the data of conventional clinical, special and radionuclide methods (RIA CEA, AFP, IRI ACTH in serum, gamma scintigraphy of liver) was carried out. For a selection of 17 parameters the factor analysis was used. Diagnostic significance of every parameter was determined. CEA and AFP markers were included as indices of tumor activity, ACTH and IRI markers were used as characterization of an organism's response to therapy. In the results of the multifactor investigations the monitoring programs 'Diagnosis-1' and 'Diagnosis-2' were developed. These programs permit to evaluate the treatment efficiency and correct the treatment schemes the case of the absence of the effect. Programmes 'Diagnosis-1' and D iagnosis-2' have a high both the diagnostic (89.9 ± 0.9% and 87.1 ± 0.9 %) and the prognostic (85.2 ± 1.3 % and 83.2 ± 1.3 %) significance. It is concluded that use of radionuclide methods permit to provide an adequate treatment in every case of rectal carcinoma. We suggesting: Use the D iagnosis-1' for evaluation of efficiency of different methods of treatment (CEA-produced tumors of rectum). Use the 'Diagnosis-2' for evaluation of efficiency of treatment of the CEA un-produced tumors of rectum. For objective and quantitative evaluation of the cancer of rectum it is necessary to determine the CEA and AKTH level in blood serum

In the years 1962-1966 225 patients with carcinoma of the rubor labiorum were observed in the Institute of Oncology in Gliwice. The patients were treated surgically or with X-rays. In the group of 204 treated patients the 5-year survival rate was 86% without signs of recurrence (after taking into consideration the natural mortality in the population). Advanced cases were treated mostly with X-rays. Evaluation of nominal standard dose on tissues showed best results in the group in which this dose was about 1700 r.

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

After statistical analysis of the results of treatment (drawn from case reports and data collected over 31 years, which were investigated for histological findings, five-year survival rates, sex and age distributions, formation of metastases), the author came to the following conclusions: 1) Total strumectomy was the most succesful method of treatment. 2) In papillary tumours, 131-radioiodine led to the best results that were quite independent of the patient's age. It is of particular note that no further metastases appeared in those cases where metastatisation could be kept under control for the first two years. 3) Controversial findings were revealed as to the therapeutic success in follicular carcinomas. 4) Huethle's oncocytoma rather appears to be of a benign nature, major therapeutic problems are posed by anaplastic tumours. Further surgical measures are recommended to be taken especially in tumours showing structural differentiation. (TRV) [de

Tonsillary carcinoma after temozolomide treatment for glioblastoma multiforme: treatment-related or dual-pathology?

Science.gov (United States)

Binello, E; Germano, I M

2009-08-01

Glioblastoma multiforme is a primary malignant brain tumor with a prognosis of typically less than 2 years. Standard treatment paradigms include surgery, radiation therapy and temozolomide. Little data exists for temozolomide recommendations after the first 6 months. We present a case of a patient with glioblastoma multiforme treated with surgery, radiation and chronic temozolomide for 6 years. He continues to survive glioblastoma-recurrence-free, but developed tonsillary carcinoma. This case raises the question of whether this secondary solid-organ malignancy is treatment-related or dual pathology.

Effect of non-specific prophylaxis of thrombogenic complications on delayed results of combined treatment of bladder carcinoma

Popov, A.I.

1987-01-01

Altogether 106 patients with bladder carcinoma (Stage T 3 N x M 0 ) after combined treatment were followed-up for 5 yrs. Nicotonic acid and aspirin at common doses were adminstrated to 51 patients (the 1st group) during pre- and postoperative radiation therapy. The other 55 patients (the 2nd group) did not receive these drugs. Relapses were noted in 33.3% of the patients of the 1st group and in 76.3% of the patients of the 2nd group. The 5-year survival in the 1st group was 72.5% and in the 2nd group 27.4%. The administration of nicotonic acid and aspirin to patients during pre- and postoperative γ-beam therapy was shown to raise the body antitumor resistance

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

Purpose A retrospective analysis of risk factors for late neurological toxicity after nasopharyngeal carcinoma radiotherapy. Patients and methods Between 1993 and 2004, 239 patients with non metastatic nasopharyngeal carcinoma were treated by radiotherapy associated or not to chemotherapy. Radiotherapy was delivered with two modalities: hyperfractionated for 82 patients and conventional fractionation for 157 patients. We evaluated the impact of tumour stage, age, gender, radiotherapy schedule and chemotherapy on neurological toxicity. Results After a mean follow-up of 107 months (35-176 months), 21 patients (8.8%) developed neurological complications, such as temporal necrosis in nine cases, brain stem necrosis in five cases, optics nerve atrophy in two cases and myelitis in one case. Five- and ten-year free of toxicity survival was 95 and 84% respectively. Young patients had greater risk of temporal necrosis, and hyperfractionated radiotherapy was associated with a significantly higher risk of neurological complications (14.6% vs 5.7%, p = 0.02). On multivariate analysis, hyperfractionation and age were insignificant. Conclusion Late neurological toxicity after radiotherapy for nasopharyngeal carcinoma was rare. Younger age and hyperfractionation were considered as risk factors of neurological toxicity in our study

Koay, Eugene J.; Teh, Bin S.; Paulino, Arnold C.; Butler, E. Brian

2012-01-01

Purpose: Treatment for small-cell carcinoma of the bladder is largely guided by case reports, retrospective reviews, and small prospective trials. This study aimed to study outcomes using a large population-based database. Methods: The Surveillance, Epidemiology, and End Results–Medicare database (1991–2005) was used to analyze how different treatment combinations of specific bladder surgeries, chemotherapy, and radiation affected patient outcomes. Trends in the use of these combinations over time were also analyzed. Results: A total of 533 patients were retrieved from the database. A bladder-sparing approach involving transurethral resection of the bladder tumor (TURBT) combined with chemotherapy and radiation yielded no significant difference in overall survival compared with patients undergoing at least a cystectomy (of whom over 90% received radical cystectomy) with chemotherapy (p > 0.05). The analysis of treatment trends indicated that these two general strategies for cure combined to account for fewer than 20% of patients. A majority of patients (54%) received TURBT as their only surgical treatment, and a subset analysis of these patients indicated that chemotherapy played a role in all stages of disease (p < 0.05) whereas radiation improved overall survival in regional-stage disease (p < 0.05). Conclusion: Relatively few patients with small-cell carcinoma of the bladder receive potentially curative therapies. Chemotherapy should be a major component of treatment. Cystectomy and bladder-sparing approaches represent two viable strategies and deserve further investigation to identify the patients who may benefit from organ preservation or not. In addition, the role of radiation in regional-stage disease should be investigated further, because it positively affects survival after TURBT.

The incidence of ductal carcinoma in situ (DCIS) has increased markedly in recent decades. In the past, mastectomy was the primary treatment for patients with DCIS, but as with invasive cancer, breast-conserving surgery followed by radiation therapy (RT) has become the standard approach. We present the final results of a multi-institutional retrospective study of an Italian Radiation Oncology Group for the study of conservative treatment of DCIS, characterized by a very long period of accrual, from February 1985 to March 2000, and a median follow-up longer than 11 years. A collaborative multi-institutional study was conducted in Italy in 10 Radiation Oncology Departments. A consecutive series of 586 women with DCIS histologically confirmed, treated between February 1985 and March 2000, was retrospectively evaluated. Median age at diagnosis was 55 years (range: 29–84); 32 patients were 40 years old or younger. All women underwent conservative surgery followed by whole breast RT. Irradiation was delivered to the entire breast, for a median total dose of 50 Gy; the tumour bed was boosted in 295 cases (50%) at a median dose of 10 Gy. After a median follow-up of 136 months (range: 16–292 months), 59/586 patients (10%) experienced a local recurrence: invasive in 37 cases, intraductal in 20 and not specified in two. Salvage mastectomy was the treatment of choice in 46 recurrent patients; conservative surgery in 10 and it was unknown in three patients. The incidence of local recurrence was significantly higher in women younger than 40 years (31.3%) (p= 0.0009). Five patients developed distant metastases. Furthermore 40 patients developed a contralateral breast cancer and 31 a second primary tumour in a different site. The 10-year actuarial overall survival (OS) was 95.5% and the 10-year actuarial disease-specific survival (DSS) was 99%. Our results are consistent with those reported in the literature. In particular it has been defined the importance of young age (40

Purpose/Objective: To reduce the incidence of radiotherapy induced xerostomia, we developed techniques of external beam irradiation with preservation of parotid function for patients with early to intermediate stage carcinomas of the head and neck. This analysis reports the efficacy of our methods. Materials and Methods: From 1985 to 1993, 42 patients with early to intermediate stage (T 1-3 N 0-2 M 0 ) head and neck carcinomas received a course of external beam radiotherapy. There were 13 patients with carcinoma of the oropharynx, 26 with carcinomas of the oral cavity and 3 with carcinomas of the hypopharynx (lateral wall). 7 patients received a course of definitive radiotherapy (66 to 72 Gy), while 35 patients received a course of postoperative radiotherapy (60-66 Gy). The fraction size was 2 Gy per day. In terms of treatment planning, the primary site (plus a margin) and the ipsilateral neck were covered by the irradiation volume. The ipsilateral parotid gland was within the treatment volume while the contralateral parotid gland was not. The most frequently used field arrangement was a paired wedge fields with an AP (medially just across the mid-line) and an ipsilateral posterior oblique field (usually 30 deg. off vertical axis with a spinal cord block). Multiple level of contours were taken and transmission blocks were used to improve dose homogeneity. In all patients, the ipsilateral parotid gland (and the neck) was irradiated while the contralateral parotid gland (and the neck) was not. Results: With a median follow up of 4 years (ranged from 1.5 to 9 years), only one patient developed symptomatic xerostomia. None had radiation induced dental caries. No patient developed recurrent disease in the contralateral neck. The local control rate was (38(42)) (90%) in the primary site and(41(42)) (98%) in the ipsilateral neck. Conclusion: With appropriate treatment planning, external beam irradiation with parotid function preservation can be achieved. Our results

To determine whether doxorubicin-piroxicam combination is safe and has activity against transitional cell carcinoma in dogs. Data was collected retrospectively from 34 dogs from two institutions over a 6-year period. Signalment, clinical presentation, treatment specifics, adverse events, response, progression-free survival and overall survival time were evaluated. Dogs received doxorubicin every 3 weeks and daily piroxicam; 17 dogs (50%) had surgery. Clinical presentations were those typically reported for transitional cell carcinoma. Mean number of doses administered was 3·5. Of the 23 dogs with measurable disease, 14 (60·5%) had stable disease, 7 (30·5%) had progressive disease and 2 (9%) a partial response. Adverse events were generally manageable, and gastrointestinal in origin; one dog died of treatment-related complications. Overall median progression-free survival and overall survival were 103 and 168 days, respectively. Cytoreductive surgery did not result in prolongation of progression-free survival, but significantly prolonged overall survival. All dogs but one died as a result of disease progression. Doxorubicin-piroxicam combination therapy is well-tolerated in dogs with transitional cell carcinoma although progression-free survival, overall survival and biological response rates appear modest. Combination with surgery appears to offer a survival advantage; however, this may reflect tumour location and volume. Prospective studies are necessary to compare activity of combination doxorubicin-piroxicam to currently applied therapies. © 2013 British Small Animal Veterinary Association.

Vascular complications after this treatment are rare. Artery stenosis or occlusions, more often iliac, are well recognized complications of postoperative radiotherapy. These segmental lesions, sometimes, are pathological lesions similar to arteriosclerotic changes. These lesions may be corrected later on after the treatment of carcinoma of the cervix. The venous complications often present later and tall within the context of post thrombotic syndrome. Conservative treatment is indicated alone. A well recognized complication, lymphedema is usually mild; a superimposed iliofemoral thrombophlebitis often may be suspected [fr

Purpose: The aim of this study was to investigate the treatment results of postoperative radiotherapy (PORT) on squamous cell carcinoma of the oral cavity (OSCC). Materials and Methods: This study included 302 OSCC patients who were treated by radical surgery and PORT. Indications for PORT include Stage III or IV OSCC according to the 2002 criteria of the American Joint Committee on Cancer, the presence of perineural invasion or lymphatic invasion, the depth of tumor invasion, or a close surgical margin. Patients with major risk factors, such as multiple nodal metastases, a positive surgical margin, or extracapsular spreading, were excluded. The prescribed dose of PORT ranged from 59.4 to 66.6Gy (median, 63Gy). Results: The 3-year overall and recurrence-free survival rates were 73% and 70%, respectively. Univariate analysis revealed that differentiation, perineural invasion, lymphatic invasion, bone invasion, location (hard palate and retromolar trigone), invasion depths ≥10mm, and margin distances ≤4mm were significant prognostic factors. The presence of multiple significant factors of univariate analysis correlated with disease recurrence. The 3-year recurrence-free survival rates were 82%, 76%, and 45% for patients with no risk factors, one or two risk factors, and three or more risk factors, respectively. After multivariate analysis, the number of risk factors and lymphatic invasion were significant prognostic factors. Conclusion: PORT may be an adequate adjuvant therapy for OSCC patients with one or two risk factors of recurrence. The presence of multiple risk factors and lymphatic invasion correlated with poor prognosis, and more aggressive treatment may need to be considered.

This study aims to investigate the effects of treatments on the quality of life for patients with esophageal squamous cell carcinoma patients diagnosed at early and late stages. From a medical center in central Taiwan, patients who had been diagnosed with esophageal squamous cell carcinoma from February 2007 and March 2011 were recruited. Using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30) and the Quality of Life Questionnaire Oesophageal 18 (QLQ-OES18), quality of life scores for 105 esophageal squamous cell carcinoma patients were obtained and assessed. Multivariate analysis was performed on the quality of life scores after stratification by cancer stage. Among early-stage esophageal squamous cell carcinoma patients, those received only surgery (S-only) performed better in physical and social functioning compared with patients who underwent surgery and concurrent chemoradiotherapy (S+CCRT) (β = 9.0, P = 0.03; β = 12.1, P = 0.04, respectively). For those that received only concurrent chemoradiotherapy (CCRT-only), they performed worse in role and emotional functioning relative to S+CCRT patients (β = -17.2, P = 0.02; β = -15.7, P = 0.05, respectively). Among late-stage patients, CCRT-only treatment gave insignificantly better global health status and functional scale scores and less severe symptoms compared to the S+CCRT option. Better functional scores and less aggravated symptoms are observed in early-stage esophageal squamous cell carcinoma patients who received surgery-only treatment relative to those that underwent both surgery and chemoradiotherapy. For late-stage esophageal cancer patients, the measured difference of quality of life is not significant between CCRT-only and S+CCRT treatments. © The Authors 2017.

1982-01-01

This dissertation is a study concerning the treatment and corresponding results of 332 patients with an invasive cervical carcinoma. The purpose of this investigation is to gain insight into the efficacy of the treatment used and, if necessary, to suggest guidelines for its improvement. In chapter I, a historical overview is given of both treatment modalities, radiotherapy and surgery, which are used in patients with cervical carcinoma. A discussion of the advantages and disadvantages of both methods follows. In chapter II, an overview is given of the composition of the group of patients studied. A systematic overview of the treatment methods is given, followed by a discussion of the items covered in this study. In chapter III, in which the combined modality treatment is discussed, a detailed consideration is given of the motivation for using a combination of radiotherapy and surgery. In chapter IV, the group of patients treated exclusively by radiotherapy is considered. In chapter V, attention is focused on the localisation of the recurrences and the relationship of this localisation with regard to the target area of the primary treatment. In chapter VI there is a discussion of the complications of treatment. In the combined modality treatment, most complications appear to occur as a result of the surgical treatment. The final chapter contains the conclusions and discussions. (Auth.)

Purpose: We retrospectively evaluated the clinical, radiological and pathological features determining the prognosis of patients with nasopharyngeal carcinoma in Ankara Oncology Hospital, Turkey. Material and Methods: Two hundred and fifty-nine patients, 74 women and 185 males with nasopharyngeal carcinoma were treated between 1993 and 2008. All imaging data including CT and MRI were reevaluated according to the criteria which determine parapharyngeal, oropharyngeal, nasal, skull-base (bone)/sinus, infra temporal fossa, orbit, intracranial involvements and lymph node metastasis by our radiologists. The patients were re staged using the AJCC 2002 classification with these new radiological findings and clinical data base. We evaluated prognostic factors using univariate Kaplan- Meier and multivariate Cox regression analyses. Gender, age (40-year cut-off), histology, T- and N-stage, tumor size, regional involvement, radiotherapy and/or chemotherapy and response to therapy were studied as variables. Results: Five-year disease-free and overall survival rates were 45±4% and 72±3%, respectively. We found that age, gender, WHO type, radiotherapy and/or chemotherapy, N-stage and response to therapy were significant prognostic factors on disease-free survival and overall survival. In the chemo-radiotherapy group, we did not detect any survival difference between patients given four or fewer chemotherapy courses. Conclusions: Radiotherapy improved survival but chemotherapy, in the neoadjuvant and adjuvant setting, had no added effect to radiotherapy. N-stage and response to treatment were the most important independent predictors on survival. Age, gender, type, therapy and bone/sinus involvement were among the predictive factors on multivariate analysis, as well.

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

This present work reports the long term results after endoscopic laser treatment in 474 patients with benign rectosigmoid villous adenomas revealed by biopsy. Two types of wavelength were used: The 1.06 micrometers infrared light from the Nd:YAG laser and the green light from the argon laser or the Nd:YAG frequency doubled laser. In some patients, both wavelengths were used. Treatment was completed in 415 patients. Total tumor destruction was obtained in 92.8% of them, a carcinoma was detected in 6.5% on biopsy specimens obtained during laser treatment, and benign villous tissue persisted in 0.7%. During the average 30 mo. follow up period of the patients with total tumor destruction, 18% had a tumor recurrence. Treatment was well tolerated with a 1.8% complication rate (one perforation, one hemorrhage, and 7 stenosis requiring dilatation). Because treatment is long and difficult and cancer rate is high, endoscopic laser should be limited in patients with a circumferential villous adenoma to nonsurgical candidates. The risk of complication after surgery (some being fatal) has to be balanced against the risk of undetected carcinoma in the other patients and the indication for endoscopic laser treatment should be discussed case by case.

Full Text Available "nBackground: Treatment of cervical carcinoma is routinely performed with Low Dose Rate (LDR brachytherapy, but Brachytherapy in our department is done with Medium Dose Rate (MDR due to the technical characteristics of the machine available here. Thus we decided to evaluate the results of this treatment in our department in a prospective study. "nMethods: Between March 2006 and July 2008, 140 patients with histologic diagnosis of cervical carcinoma referred to Tehran Cancer Institute; were treated with external beam radiotherapy (44-64 Gy to whole pelvis and MDR brachytherapy (8-30 Gy to Point A with a dose rate of 2.2±0.3 Gy/h. "nResults: 121 patients were followed up for a median time of 18 months (range: 9-39 m. There were 11%(6/54 local recurrence for surgery and adjuvant radiotherapy group; 25%(16/65 for radical radiotherapy group, and 19%(23/121 for all patients. Rectal and bladder complications incidence for all patients were 10%(12/121 and 13%(16/121 respectively. High grade complication was shown only in one patient in radical radiotherapy group. In this study 3-years disease free survival and overall survival were 73% and 92% respectively, and disease stage (p=0.007 and overall treatment time (p=0.05 were the significant factors affecting disease free survival. "nConclusions: Results of this series suggest that the use of external beam radiotherapy and MDR brachytherapy with about 20% dose reduction in comparison with LDR can be an acceptable technique with regard to local control and complications.

Objective: To evaluate the clinical efficacy of transcatheter hepatic arterial thermo-chemotherapy and thermo-lipiodol embolization in the treatment of hepatic metastases from colorectal carcinoma. Methods: Sixty-eight cases with hepatic metastases from colorectal carcinoma were equally and randomly divided into two groups. The patients in study group were treated with transcatheter hepatic arterial thermo-chemotherapy and thermo-lipiodol embolization, while the patients in control group were treated with conventional (normal temperature) transcatheter hepatic arterial chemotherapy lipiodol embolization. Results: The effective rate of study group and control group was 65%(22/34) and 32%(11/34) respectively, the difference between two groups was statistically significant (P<0.05). No significant difference in the postoperative changes of hepatic function tests was found between the two groups. The survival rate at 6,12,18 and 24 months after the treatment was 100%, 82%, 44% and 18% respectively in study group, while it was 91%, 47%, 15% and 6% respectively in control group. Conclusion: Transcatheter hepatic arterial thermo-chemotherapy and thermo-lipiodol embolization is an effective and safe treatment for the hepatic metastases from colorectal carcinoma and has no obvious damage to the hepatic function.

1999-01-01

Objectives: To conduct a survey of the angiosarcomas developing after breast conservation for carcinoma in the French Cancer Centers, to study the evolution of these cases in detail, and to review literature in an attempt to propose an optimal treatment scheme. Material and Methods: Eleven of the 20 French Cancer Centers agreed to research and retrospectively analyze all angiosarcomas discovered in patients previously treated by conservative treatment. The majority of the patients were node negative, T1N0M0. The mean age of the patients at the time of primary breast cancer treatment was 62.5 years, and 69 years at the diagnosis of the angiosarcoma. Results: During the last two decades, nearly 20,000 patients have been treated conservatively in these 11 centers, and only 9 cases of angiosarcoma were found. The median latency period between the treatment of the breast carcinoma and the diagnosis of the breast angiosarcoma was approximately 74 months, with a range of 57-108 months. Mastectomy was performed as the main treatment of this angiosarcoma. All recurrences after mastectomy for the angiosarcoma appeared within 16 months after the mastectomy. A median time of recurrence was found to be 7.5 months, regardless of the treatment. The angiosarcomas appeared to be very aggressive, and chemotherapy, radiotherapy, and sometimes hyperthermia could only palliate the condition for a short time. After the diagnosis of angiosarcoma, the median survival was 15.5 months, showing a particularly poor prognosis. Only 1 patient of 9 is alive without progressive disease at 32 months after salvage mastectomy for the recurrence of the angiosarcoma. Precise data obtained from 11 centers show that, of 18115 breast carcinomas treated conservatively, only 9 breast angiosarcomas are reported, which represents a prevalence of 5 cases of angiosarcoma per 10,000, which is the same prevalence for primary breast angiosarcomas occurring in healthy breasts. Conclusion: Angiosarcoma developing

The efficacy of radiation therapy for feline advanced cutaneous squamous cell carcinoma was evaluated. A full course radiation therapy protocol was applied to six cats showing single or multiple facial squamous cell carcinomas, in a total of seven histologically confirmed neoplastic lesions. Of the lesions, one was staged as T 1 , and six as T 4 according to WHO staging system of epidermal tumors. The animals were submitted to twelve radiation fractions of 4 Gy each, on a Monday-Wednesday-Friday schedule, and the equipment used was an orthovoltage unit. Energy used was 120 kV, 15 mA and 2 mm aluminum filter. The cats were evaluated during the treatment and 30 and 60 days after the end of the radiation therapy. In this study, 87% of the lesions had complete remission and 13% partial remission to the treatment. Side effects were considered mild according to Veterinary Radiation Therapy Oncology Group Toxicity criteria, and included erythema, epilation and rhinitis. Radiation Therapy was considered safe for feline cutaneous squamous cell carcinoma, leading to mild side effects and can represent a good therapeutic option. (author)

Combined radio- and hormone therapy of the prostate carcinoma

Papic, R.

1979-08-01

Intention of this study is to detect in 49 patients suffering from prostate carcinomas, effects and side effects of radiotherapy. According to the present results, there is not any doubt that prostate carcinomas are radiosensitive. In all patients radiotherapy induced a prostate shrinkage and an increasing of consistency. It resulted that a prostate biopsy must be carried out in order to control the success of therapy. The success of the treatment depends upon tumour spreading and on its degree of differentiation. Within the observation period only in four cases metastasation of the prostate carcinoma occurred after radiotherapy. According to literature, the 5-year survival rate with an organ-defined prostate carcinoma ranges between 70 and 80% when radiotherapeutic methods are applied. The same authors indicate a 5-year survival rate between 42 and 48% for scattered carcinomas. Only minor side effects are provoked by radiotherapy. In 75% of the patients pollakisuria and dysuria resulted. After irradiation was finished, the symptoms disappeared and did not cause in any case any late complications. In 12% of the cases proctitic pain occurred during irradiation, which in 6% remained even after the treatment was terminated. We could prove unequivocally on our patients that passage impairments caused by a prostate carcinoma are improved by radiotherapy. Finally it can be said that this treatment is applicable for curing carcinoma which is localised on the prostate. In the case of an undefined, scattered carcinoma radiotherapy combined with hormone therapy is the treatment of choice. With regards to undesired side effects radiotherapy is superior to other therapeutic measures. (orig./MG) [de

Neoadjuvant treatment intensification or adjuvant chemotherapy for locally advanced carcinoma rectum: The optimum treatment approach remains unresolved

International Nuclear Information System (INIS)

Mallick, S.; Benson, R.; Haresh, K.P.; Rath, G.K.

2015-01-01

Background: Rectal carcinoma [RC] is often managed with preoperative radiotherapy or radio chemotherapy followed by total meso rectal excision (TME). Efforts are being made to improve outcome by intensifying the preoperative treatment. However, the optimum therapy remains unclear. There is ongoing controversy regarding the optimum radiation dose, chemotherapy regimen and schedule. In addition there exists growing disagreement regarding the role of adjuvant chemotherapy after neoadjuvant radiation or chemo radiation. Methodology: We reviewed the recent land mark trials to find a road map in the management of locally advanced rectal carcinoma. Results: Preoperative short course radiotherapy has long been proven to improve local disease con- trol. The initial trials with long course chemoradiotherapy, comparing short course radiotherapy have shown to increase local control and pathological complete response rates. Since then treatment intensification of this neoadjuvant schedule has been tried by many researchers. But initial results of these treatment intensification trials, show no significant benefit and are associated with increased toxicity. There is an unmet need to stratify patients depending on risk to assign them to long course chemoradiotherapy or short course radiotherapy. Current evidence does not support the use of adjuvant chemotherapy in patients who were treated with preoperative (chemo)radiotherapy. Conclusion: Preoperative radiotherapy appears to improve disease control with favorable toxicity profile and there is very little to choose between long course chemoradiotherapy and short course radiotherapy. However, long course chemoradiotherapy may be beneficial for patients with high risk features like positive circumferential resection margin [CRM] and extramural spread of >5 mm. There is no role for adjuvant chemotherapy in patients who were treated preoperative (chemo)radiotherapy

Full Text Available Objective: To study the effect of integrated surgery + radiotherapy + chemotherapy treatment on the survival status and serum indexes in patients with gallbladder carcinoma. Methods: A total of 68 patients with gallbladder carcinoma were divided into observation group (received integrated surgery + radiotherapy + chemotherapy treatment and control group (received surgery + radiotherapy according to different treatments. Differences in the content of tumor markers, growth factors and adhesion molecules in serum as well as the median survival time and survival rate in 5 years of follow-up were compared between the two groups 1 month after treatment. Results: Tumor markers β2-MG, CA19-9, CA242, CA125, CA724, CEA and AFP content in serum of observation group after treatment were significantly lower than those of control group; growth factors VEGF, FGF, EGFR and HER2 content in serum were significantly lower than those of control group while IGFBP-2 and IGFBP-3 content were significantly higher than those of control group; adhesion molecules E-selectin, ICAM-1, VCAM-1 and sE-Cd content in serum were significantly lower than those of control group; the median survival time of 5-year follow-up as well as 1-, 3- and 5-year survival rate were significantly greater than those of control group. Conclusions: Integrated treatment of surgery + radiotherapy + chemotherapy can optimize the short-term and long-term curative effect in patients with gallbladder carcinoma.

To evaluate the predictive factors for treatment response and prognostic factors affecting survival outcomes after concurrent chemoradiotherapy (CCRT) for patients with anal squamous cell carcinoma. Medical records of forty two patients with histologically confirmed analsquamous cell carcinoma, who had complete CCRT between 1993 and 2008, were reviewed retrospectively. Median age was 61.5 years (39-89 years), and median radiotherapy (RT) dose was 50.4 Gy (30.0-64.0 Gy). A total of 36 patients had equal to or less than T2 stage (85.7%). Fourteen patients (33.3%) showed regional nodal metastasis, 36 patients (85.7%) were treated with 5-fluorouracil (5-FU) plus mitomycin, and the remaining patients were treated by 5-FU plus cisplatinum. The median follow--up time was 62 months (2-202 months).The 5-year overall survival, locoregional relapse-free survival, disease-free survival, and colostomy-free survival rates were 86.0%, 71.7%, 71.7%, 78.2%, respectively. Regarding overall survival, the Eastern Cooperative Oncology Group (ECOG) performance status and complete response were found to be significant prognostic factors on univariate analysis. For multivariate analysis, only the ECOG performance status was significant. No significant factor was found for locoregional relapse-free survival or disease-free survival and similarly for treatment response, no significant factor was determined on logistic regression analysis. There were 7 patients who had local or regional recurrences and one patient with distant metastasis. The only evaluable toxicity in all patients was radiation dermatitis of perianal skin (grade 3), which developed in 4 patients (9.5%) and grade 2 in 22 patients (52.4%). This study revealed that patients with a performance score of ECOG 0-1 survived significantly longer than those with a poorer score. Finally, there was no significant predicting factors tested for treatment response.

The optimal treatment of ductal carcinoma in situ (DCIS) of the breast has not yet been established. The effectiveness of adjuvant postoperative radiotherapy after conservative surgery is debated. Few data are available in Italy on the combined treatment. A collaborative multi-institutional study on this issue in 10 radiation oncology departments of the north-east of Italy was conducted. One hundred and thirty nine women with DCIS of the breast were treated between 1980 and 1990. Age ranged between 28 and 88 years (median 50 years). Surgical procedures were: quadrantectomy in 108, lumpectomy in 22 and wide excision in 9 cases. The axilla was surgically staged in 97 cases: all the patients were node-negative. Radiation therapy was delivered with 60Co units (78%) or 6 MV linear accelerators (22%) for a median total dose to the entire breast of 50 Gy (mean 49.48 Gy; range 45-60 Gy). The tumour bed was boosted in 109 cases (78%) at a dose of 4-30 Gy (median 10 Gy) for a minimum tumour dose of 58 Gy. Median follow-up was 81 months. Thirteen local recurrences were recorded, 7 intraductal and 6 invasive. All recurrent patients had a salvage mastectomy and are alive and free of disease. Actuarial overall, cause-specific and recurrence-free survival at 10 years are of 93%, 100% and 86%, respectively. The results of this retrospective multicentric study substantiate the favourable data reported in the literature and confirm the efficacy of the breast-conserving treatment of DCIS employing conservative surgery and adjuvant radiation therapy.

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

With substantially increased survival after most paediatric cancers over the past decades have come the late sequelae of treatment. Of all late complications of treatment, second malignancies are generally considered to be the most serious. We report on a 20-year-old man with an oral squamous cell carcinoma 17 years after initial chemotherapy and irradiation for acute lymphoblastic leukaemia. Although occurrence of the oral malignancy in this patient could have been treatment-related, one should keep in mind that the occurrence of second tumours may also be based on a shared genetic aetiology.

Purpose: This study's aim was to assess outcome and toxicity of high-dose-rate endoluminal brachytherapy (HDREB) for recurrent bronchial carcinoma. Methods and Materials: From 1987 to 2005, 41 patients were treated with HDREB for symptomatic recurrent bronchial carcinoma. All patients had previously undergone external beam radiotherapy (EBRT) with a median dose of 56 Gy (range, 30-70 Gy). The median HDREB dose applied was 15 Gy (range, 5-29 Gy). The median time interval between primary EBRT and reirradiation was 9 months (range, 2-54 months). Results: After a median follow-up of 6.7 months, the 6-, 12-, and 24-month overall survival rates were 58%, 18%, and 7%, respectively. The median overall survival time was 6.7 months. Local remission was achieved in 73% of patients (n = 30). A total of 24% of patients (n = 10) showed no response or progressive disease within 8 weeks after treatment. In 1 patient, treatment response was not documented. The 6-, 12-, and 24-month local control rates were 38%, 17%, and 3%, respectively. The median local progression-free survival time was 4 months (range, 1-23 months). Prognostic factors were a total dose of ≥15 Gy of HDREB (p = 0.029) and a Karnofsky performance score of ≥80% (p = 0.0012). The cause of death was locoregional progression in 27% of patients (n = 11), distant metastases in 24% of patients (n = 10), fatal hemorrhage in 15% of patients (n = 6), and other causes in 29% of patients (n = 12). None of the patients with locally controlled disease showed grade 3 or 4 late effects. Conclusions: Palliative treatment of symptomatic, locally recurrent bronchial carcinoma with HDREB can effectively relieve symptoms in the majority of patients while causing only few complications. Still, time to progression is short.

Radiotherapy - an effective treatment for vaginal verrucous carcinoma

Reinecke, L.; Thornley, A.L.

1993-01-01

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

Merkel cell carcinoma (MCC) is an uncommon primary cutaneous carcinoma with neuroendocrine differentiation. Since recent discovery of MCCs strong association with Merkel cell polyomavirus (MCPyV), there has been a rapid increase in the understanding of the carcinomas genetics, molecular biology and pathogenesis. In our study, we reviewed recent advances and controversies concerning MCC histogenesis, epidemiology, diagnostic and prognostic markers. We analyzed the association of MCPyV with MCC and the possible new targets for therapy. We also examined English-based literature regarding MCC pathogenesis published between 2008 and 2013, which lead to a deeper understanding of the topic. Our study showed that the association of MCPyV strongly influences the course of MCC. Additionally, it has been shown that a immunological response to MCPyV may in the future give hope to identify new therapeutic strategies in treatment of this fatal malignancy.

Full Text Available ABSTRACT Hepatocellular carcinoma is a malignancy of global importance and is associated with a high rate of mortality. Recent advances in the diagnosis and treatment of this disease make it imperative to update the recommendations on the management of the disease. In order to draw evidence-based recommendations concering the diagnosis and management of hepatocellular carcinoma, the Brazilian Society of Hepatology has sponsored a single-topic meeting in João Pessoa (PB. All the invited pannelists were asked to make a systematic review of the literature and to present topics related to the risk factors for its development, methods of screening, radiological diagnosis, staging systems, curative and palliative treatments and hepatocellular carcinoma in noncirrhotic liver. After the meeting, all panelists gathered together for the discussion of the topics and the elaboration of those recommendations. The text was subsequently submitted for suggestions and approval of all members of the Brazilian Society of Hepatology through its homepage. The present paper is the final version of the reviewed manuscript containing the recommendations of the Brazilian Society of Hepatology.

Purpose: To describe efficacy and safety of stereotactic body radiation therapy (SBRT) for the treatment of inoperable hepatocellular carcinoma. Methods: The records of 77 consecutive patients treated with SBRT for 97 liver-confined HCC were reviewed. A total dose of 45 Gy in 3 fractions was prescribed to the 80% isodose line. Local control (LC), overall survival (OS), progression-free survival (PFS) and toxicity were studied. Results: The median follow-up was 12 months. The median tumor diameter was 2.4 cm. The LC rate was 99% at 1 and 2 years. The 1 and 2-year OS were 81.8% and 56.6% respectively. The median time to progression was 9 months (0–38). The rate of hepatic toxicity was 7.7% [1.6–13.7], 14.9% [5.7–23.2] and 23.1% [9.9–34.3] at 6 months, 1 year and 2 years respectively. In multivariate analysis, female gender (HR 7.87 [3.14–19.69]), a BCLC B-C stage (HR 3.71 [1.41–9.76]), a sum of all lesion diameters ⩾2 cm (HR 7.48 [2.09–26.83]) and a previous treatment (HR 0.10 [0.01–0.79]) were independent prognostic factors of overall survival. Conclusion: SBRT allows high local control for inoperable hepatocellular carcinomas. It should be considered when an ablative treatment is indicated in Child A patients

We evaluated the effectiveness of radiotherapy combined with chemotherapy in patients with oral squamous cell carcinoma. Therefore, 1042 cases where reviewed in School Dentistry - Osaka Univ. Seven hundred and fifteen were male and three hundred and twenty-seven were female. Ora cancer was affected more male than female patients, with mean age of 582 years old. The tongue was the most common anatomic localization of oral cancer. In tongue, the use of external radiotherapy y combined with brachytherapy and brachytherapy isolated presented better results than chemotherapy combined with external radiotherapy. In buccal mucosa, there was not differences in the treatment's results using external radiotherapy and combined chemotherapy and external radiotherapy. In tongue's floor and upper and jaw gingiva the combined treatment with chemotherapy and external radiotherapy presented better results than isolated external radiotherapy. (author)

No standard second-line treatments are available for hepatocellular carcinoma patients who fail sorafenib therapy. We assessed the safety and efficacy of metronomic capecitabine after first-line sorafenib failure. Retrospective analysis of consecutive hepatocellular carcinoma patients receiving metronomic capecitabine between January 2012 and November 2014. The primary end-point was safety, secondary end-point was efficacy, including time-to-progression and overall survival. Twenty-six patients (80% Child-Pugh A, 80% Barcelona Clinic Liver Cancer stage C) received metronomic capecitabine (500 mg/bid). Median treatment duration was 3.2 months (range 0.6-31). Fourteen (53%) patients experienced at least one adverse event. The most frequent drug-related adverse events were bilirubin elevation (23%), fatigue (15%), anaemia (11%), lymphoedema (11%), and hand-foot syndrome (7.6%). Treatment was interrupted in 19 (73%) for disease progression, in 4 (15%) for liver deterioration, and in 1 (3.8%) for adverse event. Disease control was achieved in 6 (23%) patients. Median time-to-progression was 4 months (95% confidence interval 3.2-4.7). Median overall survival was 8 months (95% confidence interval 3.7-12.3). Metronomic capecitabine was well tolerated in hepatocellular carcinoma patients who had been treated with sorafenib. Preliminary data show potential anti-tumour activity with long-lasting disease control in a subgroup of patients that warrants further evaluation in a phase III study.

2006-01-01

Purpose: This Rare Cancer Network (RCN) study was performed in pediatric nasopharyngeal carcinoma (PNPC) patients to evaluate the optimal dose of radiotherapy and to determine prognostic factors. Patients and Methods: The study included 165 patients with the diagnosis of PNPC treated between 1978 and 2003. The median age was 14 years. There were 3 (1.8%) patients with stage I, 1 (0.6%) with IIA, 10 (6.1%) with IIB, 60 (36.4%) with III, 44 (26.7%) with IVA, and 47 (29%) with IVB disease. While 21 (12.7%) patients were treated with radiotherapy (RT) alone, 144 (87.3%) received chemotherapy and RT. The median follow-up time was 48 months. Results: The actuarial 5-year overall survival (OS) was 77.4% (95% CI: 70.06-84.72), whereas the actuarial 5-year disease-free survival (DFS) rate was 68.8% (95% CI: 61.33-76.31). In multivariate analysis, unfavorable factors were age >14 years for LRC (p = 0.04); male gender for DMFS (p = 0.03); T3/T4 disease for LRFS (p = 0.01); and N3 disease for DFS (p = 0.002) and OS (p = 0.002); EBRT dose of less than 66 Gy for LRFS (p = 0.02) and LRRFS (p = 0.0028); and patients treated with RT alone for LRFS (p = 0.0001), LRRFS (p = 0.007) and DFS (p = 0.02). Conclusion: Our results support the current practice of using combined radiation and chemotherapy for optimal treatment of NPC. However, research should be encouraged in an attempt to reduce the potential for long-term sequelae in pediatric patients given their relatively favorable prognosis and potential for longevity

Mucoepidermoid carcinoma of the tracheobronchial tree is a rare airway tumor (cesarean section. We report the first case to be treated by Argon-Plasma Coagulation (APC) in pregnancy. A 35-year-old Caucasian woman G1P0, at 27 weeks of gestation was admitted to the emergency department because of hemoptysis and severe dyspnea. Bronchoscopy and biopsies diagnosed primary tracheal mucoepidermoid carcinoma. Following an episode of tracheal bleeding, she was intubated. After thorough explanations to the family and obtaining informed consent, therapeutic bronchoscopy, under general anesthesia using a rigid bronchoscope, was performed. The tumor was cored out with the tip of the bronchoscope and removed with an alligator forceps. The tumor bed was coagulated with APC. The obstetrical team was ready to intervene in case of maternal emergency. Immediate follow-up was good, and she left the hospital 4 days later. She delivered at 39 weeks of gestation by cesarean section because of dystocia. Five years later, the patient is doing well without any signs or symptoms of recurrence. Pediatric follow-up is normal. Argon Plasma Coagulation for treatment of mucoepidermoid tracheal carcinoma is feasible during pregnancy. Reporting this case could lead to less aggressive management of mucoepidermoid carcinoma in pregnant patients.

The best way to treat locally recurrent carcinoma of the uterine cervix has not been established. This retrospective study refers to 37 consecutive patients, with recurrence in the pelvis, treated by radiotherapy alone. Thirty patients were treated by external beam therapy alone; intracavitary brachitherapy alone was adopted in 3 patients and a combination of both techniques in 4 patients. The total radiation dose exceeded 60 Gy in 62% of cases. A complete clinical response was observed in 54% of patiens and a partial response in 32.4%. Overall crude survival was 70.3%, 28.9% and 23.2% at 1, 3 and 5 years respectively. In patients with recurrent tumors less than 40 mm in diameter a threefold 3-year survival was achieved (48.6% vs. 14.5%, p<0.025). With total doses higher than 60 Gy the 3-year survival resulted to be far better than with lower doses (39.1% vs. 10%, p<0.025). A significant advantage was also observed in the ''complete responders'' group (44% vs. 11.8%), but this difference can be explained by the link between response and the above-mentioned basic prognostic factors. Acute side effects and late complications were moderate and did not correlate with the type of primary treatment. A significant percentage (about 25%) of patients with locally recurrent cervix carcinoma may reach medium-term survival; better results can be achieved in selected groups with favourable prognostsc factors and with adequate radiotherapic treatment

Supraestructure maxillectomy and orbital exenteration for treatment of basal cell carcinoma of inferior eyelid: Case report and review

Directory of Open Access Journals (Sweden)

Villalon-Lopez J

2006-01-01

Full Text Available Basal cell carcinoma (BCC is the most frequent type of skin cancer in humans, with cumulative exposure to ultraviolet radiation as an important risk factor for development of illness such as severe solar burns during childhood or adolescence. BCC is mainly located on sun-exposed sites, head and neck being the areas of more incidences; although nose, eyelids and periorbitary tissue are unfavorable due to cosmetic results that BCC involves. Tumors can be classified as nodular, superficial, micronodular, morphea variety, infiltrating, pigmented, metatypic and fibroepithelioma of Pinkus. Several treatment options such as surgical and nonsurgical are available. The goal of treatment is complete excision of the tumor with preservation of surrounding structures in a way aesthetically acceptable. Mohs′ micrographic surgery is the standard treatment for all nonmelanoma skin cancers. Orbital exenteration is also used for treatment of malignancies of ocular tissues, mainly squamous cell carcinoma, sebaceous cell carcinoma and BCC. The tissue beneath the surgical site can be left for second-intention granulation or covered with a cutaneous implant of partial thickness. The case of a 77-year-old patient is presented with BCC of inferior eyelid of 14 years′ duration, formerly managed with radiotherapy; however, due to recurrent illness and invasion to the maxillary antrum, he needed supraestructure maxillectomy with left orbital exenteration.

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

Science.gov (United States)

2014-01-01

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

Neglected Giant Scalp Basal Cell Carcinoma

Directory of Open Access Journals (Sweden)

Anne Kristine Larsen, MD

2014-03-01

Full Text Available Summary: Rarely, basal cell carcinoma grows to a giant size, invading the underlying deep tissue and complicating the treatment and reconstruction modalities. A giant basal cell carcinoma on the scalp is in some cases treated with a combination of surgery and radiation therapy, resulting in local control, a satisfactory long-term cosmetic and functional result. We present a case with a neglected basal cell scalp carcinoma, treated with wide excision and postoperative radiotherapy, reconstructed with a free latissimus dorsi flap. The cosmetic result is acceptable and there is no sign of recurrence 1 year postoperatively.

2004-01-01

The purpose of this study was to assess the anatomic and functional outcomes and compare the voice quality in patients affected by T1a glottic carcinoma treated with curative intent with radiotherapy or laser cordectomy. Fifty-seven cases were analysed: 27 after curative radiotherapy and 30 after laser cordectomy. All patients were studied with videolaryngostroboscopy, voice analysis by narrow spectrogram, and vocal parameters (Jitter, Shimmer, noise/harmonic ratio, and diplophonia). Videolaryngostroboscopy showed severe glottic inadequacy in 25% of cases treated with radiation and insufficient compensation 'ventricular band' or 'with arytenoid hyperadduction' in 65% of cases after surgery. Severe dysphonia on the electro-acoustic analysis of voice was observed in 25% of cases after radiation and 70% after laser (p<0.001). Fundamental frequency and vocal parameters showed more favourable results in the radiation group (p<0.001). Voice assessment showed better results after radiotherapy compared with laser cordectomy. Voice outcome should be carefully considered in the treatment decision for T1 glottic carcinoma

Dependence of radiotherapeutic results on tumor size in patients with cervix uteri carcinoma

International Nuclear Information System (INIS)

Gabelov, A.A.; Zharinov, G.M.

1981-01-01

A method is suggested that permits specifying the primary tumor size on the basis of clinical examination of patients with cervix uteri carcinoma. The values of tumor size have been correlated with long-term results of concomitant radiotherapy in 1358 patients with cervix uteri carcinoma. The data obtained have shown that the primary tumor size is a factor that determines to a large extent radiotherapeutic results in patients with cervix uteri carcinoma. The specification of tumor size values makes it possible to considerably lessen prognostic uncertainty of present-day staging classifications. The structure of radiotherapeutic failures also turned out to be closely associated with the primary tumor size

Investigation of acupuncture-point injection combined with intratumor injection of radionuclide phosphorus 32 in treatment of metastatic carcinoma

International Nuclear Information System (INIS)

Chou, H.C.

1986-01-01

Seventeen patients with carcinoma and three patients with benign lesions of the head were studied by acupuncture-point injection combined with intratumor injection of radionuclide P-32 for treatment of metastatic carcinoma. The metastatic cervical nodules shrank to half their original sizes within 2-3 weeks in five cases of nasopharyngeal carcinoma. The injected dose ranged from 0.222 to 0.421 mCi, approximately 10 times less than that given by the ordinary method. The acupuncture points are selected according to the Theory of Channels and Collaterals of Chinese traditional medicine. The mechanism of therapeutic action of radionuclide P-32 is possibly by the delivery of destructive ionizing radiation from beta emission properties of P-32. This method appears to offer a low-dose means of P-32 treatment of metastatic carcinoma

Combined regional chemotherapy and radiation therapy in the treatment of epidermoid carcinoma in the oro-facial region

Danko, J; Satko, I [Komenskeho Univ., Bratislava (Czechoslovakia). Lekarska Fakulta; Durkovsky, J [Institute of Clinical Oncology, Bratislava (Czechoslovakia)

1979-01-01

Treatment was studied of oro-facial epidermoid carcinoma by combined chemo- and radiotherapy and eventual surgery. Cytostatic drugs were applied intraarterially. After a monocytostatic treatment trial with Methotrexate (MTX), a combined cytostatic program was developed alternating two cytostatic drugs, viz., MTX and Bleomycin (BLM). The usefulness of chemotherapy and its inclusion in the treatment of epidermoid carcinoma in the oro-facial region was found justified for combined therapy. The selected intraarterial administration, however, is not suitable for routine application. For this reason, the combination irradiation or surgical therapy with chemotherapy was adopted.

Sensitivity and specificity of narrow-band imaging nasoendoscopy compared to histopathology results in patients with suspected nasopharyngeal carcinoma

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

Full Text Available Objective: To analyze the malignant degree of primary hepatocellular carcinoma after endostar combined with transcatheter arterial chemoembolization (TACE treatment. Methods: A total of 68 cases of patients with primary hepatocellular carcinoma treated in our hospital from September 2011 to December 2014 were enrolled for study and divided into observation group 34 cases and control group 34 cases according to different treatment methods. Control group received transcatheter arterial chemoembolization (TACE treatment, observation group received endostar combined with TACE treatment, and then differences in serum amino acid levels, micro RNA levels, levels of GP73, GPC3, GS, etc as well as levels of ChE, TBA and AFP were compared between two groups after treatment. Results: Serum aspartic acid, leucine and arginine levels of observation group after treatment were higher than those of control group, and αα-aminoadipic acid, methionine, β-alanine and 3-methylhistidine levels were lower than those of control group; relative values of serum miR-106b, miR-222 and miR-21 expression of observation group after treatment were lower than those of control group, and relative values of miR-199a and miR-122 expression were higher than those of control group; GP73, IL-17, IL-6, GPC3, GS and HSP70 levels of observation group after treatment were lower than those of control group, and endostatin level was higher than that of control group; ChE level of observation group after treatment was higher than that of control group, and TBA and AFP levels were lower than those of control group. Conclusion: Endostar combined with TACE treatment for patients with primary hepatocellular carcinoma can effectively inhibit tumor proliferation, invasion and other malignant processes and improve liver function, and it has positive clinical significance.

Following the increasing desire of many patients to keep the form and function of speech and swallowing, interstitial brachytherapy has become the main treatment for head and neck cancer. In addition, aged and physically handicapped patients who are refused general anesthesia have come to be referred to our clinic to receive less invasive and curative treatment. In the field of brachytherapy for head and neck cancers, less complicated and more superior treatment results have been achieved following the introduction of spacers, computer dosimetry and so on. As a result of these efforts, treatment results have come to fulfill the desire of patients and their families. During the past 43 years from 1962 to 2005, we have treated over 2, 100 patients of head and neck cancer including 850 with stage I·II oral tongue carcinoma by brachytherapy and acquired a lot of important and precious data including the treatment results, multiple primary cancers as well as radiation-induced cancers.

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

Full Text Available Audrey Bellesoeur, Edith Carton, Jerome Alexandre, Francois Goldwasser, Olivier Huillard Department of Medical Oncology, Hopital Cochin AP-HP, Paris, France Abstract: Since 2005, the approved first-line treatment of metastatic renal cell carcinoma consists in tyrosine kinase inhibitors (TKIs targeting the vascular endothelial growth factor receptors (VEGFRs. Axitinib is an oral second-generation TKI and a potent VEGFR inhibitor with a half maximal inhibitory concentration for the VEGF family receptors 10-fold lower than other TKIs. Axitinib activity in renal cell carcinoma (RCC patients has been studied in various settings and particularly as second-line treatment. In this setting, axitinib with clinically based dose escalation compared to sorafenib has demonstrated an improvement in progression-free survival in a randomized Phase III trial leading to US Food and Drug Administration approval. In the first-line setting, axitinib failed to demonstrate improved efficacy over sorafenib, but the field of RCC treatment is rapidly changing with novel TKIs as cabozantinib or the emergence of check point inhibitors as nivolumab and the place of axitinib in therapy is therefore challenged. In this review, we focus on axitinib pharmacological and clinical properties in RCC patients and discuss its place in the treatment of patients with RCC.

The goal of this work is to portray the effect of a high-dosed short-timed pre-irradiation on intra- and post-operative therapy of rectal carcinoma and the appearance of recidivistic tumors, respectively distant metastasis. This intermediate balance should help make the decision easier as to whether to continue to use this combined treatment form. The subjects consisted of 65 rectal carcinoma patients - pre-irradiated and operated - and 95 only operated patients. The irradiation was completed using a 8 MeV linear accelerator with ultra hard x-radiation. Dosing - (more than 80%) as short-timed irradiation with 16 Gy (4 x 4 Gy in 2 days) - 25 Gy (10 x 2,5 Gy in 12 days); average field size 150 mm x 150 mm. There were no significant differences with regard to intra- and post-operative complications, late complications or distant metastasis, but there was with tumor recidivision reduced with pre-irradiated. Regarding the survival rate, there was a slight tendency in favor of the pre-irradiated. (orig./MG) [de

1981-01-01

Between 1960 and 1978, 87 patients with locally advanced Tsub(3-4)Nsub(0-3)M 0 carcinoma of the breast were treated with 5,000 to 8,000 rad of external beam supervoltage radiotherapy. Initial clinical eradication of the tumour was observed in 76 of 87 cases (87%), but the actuarial probability of local control at 5 yr was only 53%. Furthermore, the actuarial probability of disease-free survival was 25% at 5 yr and 13% at 10 yr. Most of the patients eventually succumbed to metastatic breast carcinoma and the actuarial survival at 5 yr was 43% and at 10 yr, 16%. The addition of adjuvant low-dose chemotherapy, given to 13 patients, did not affect the rates of local control, survival or disease-free survival. The most common long-term complication was extensive and deforming radiation-induced fibrosis of the treated breast. The actuarial probability of 10-yr survival without a local recurrence and without severe fibrosis of the treated breast was only 17.5%. The role of adjuvant high-dose chemotherapy in the treatment of locally advanced breast carcinoma and the possible use of improved radiotherapy techniques to achieve a more effective long-term local control and a more desirable cosmetic end result are discussed.

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.)

ANGIOGENESIS INHIBITORS FOR THE TREATMENT OF HEPATOCELLULAR CARCINOMA

Directory of Open Access Journals (Sweden)

Massimiliano Berretta

2016-11-01

Full Text Available Background: Angiogenesis inhibitors have become an important therapeutic approach in the treatment of hepatocellular carcinoma (HCC patients. The achievement of Sorafenib in prolonging overall survival of patients with HCC makes therapeutic inhibition of angiogenesis a fundamental element of the treatment of HCC. Considering the heterogeneous aspects of HCC and to enhance therapeutic efficacy, overcome drug resistance and reduce toxicity, the combination of antiangiogenic drugs with antiblastic chemotherapy (AC, radiotherapy or other targeted drugs have been evaluated. The issue is further complicated by the combination of antiangiogenesis with other AC or biologic drugs. To date, there is no planned approach to determine which patients are more responsive to a given type of antiangiogenic treatment. Conclusion: Large investments in the clinical research are essential to improve treatment response and minimize toxicities for patients with HCC. Future investigations will need to focus on utilizing patterns of genetic information to classify HCC into groups that display similar prognosis and treatment sensitivity, and combining targeted therapies with AC producing enhanced anti-tumor effect. In this review the current panel of available antiangiogenic therapies for the treatment of HCC have been analyzed. In addition current clinical trials are also reported herein.

This is a retrospective analysis of a new treatment modality, intra-arterial administration of Yttrium-90 TheraSphere, for unresectable hepatocellular carcinoma (HCC). Patients with HCC not amenable to surgical treatment who had satisfactory physiological function without comorbid disease or significant pulmonary shunting were eligible for treatment. Patients were categorized into complete, partial, or no response based on serum alpha-fetoprotein (AFP) levels and CT or MRI imaging. Fourteen patients were considered candidates for treatment. Three patients were excluded due to significant hepatopulmonary shunting. Eleven patients were treated with TheraSphere. One patient (9%) had a complete response, eight patients (78%) had a partial response, and two patients (18%) showed no response. Partial and complete responders with AFP-associated HCC demonstrated a median decrease in AFP levels of 79 per cent at 73 days. No patients developed liver toxicity nor died due to treatment. Five patients (45%) died of progressive disease at a median of 7 months post-treatment. Six patients (54%) were alive at a median of 11 months (range, 9 to 20 months). Okuda stage 2 and 3 patients showed a median survival of 11 months and 7 months, respectively. Yttrium-90 TheraSphere treatment for unresectable hepatocellular carcinoma is well tolerated and appears to extend survival.

Johnston Mark H

2007-03-01

Full Text Available Abstract Background Esophageal carcinoma is the ninth most prevalent cancer worldwide with squamous cell carcinoma (SCCA and adenocarcinoma accounting for the vast majority of new cases (13,900 in 2003. Cure rates in the U.S. are less than 10%, similar to lung cancer. More than 50% of patients with esophageal carcinoma present with unresectable or metastatic disease, are not surgical candidates, or display disease progression despite the addition of neoadjuvant chemoradiotherapy to surgery. Need for improved palliation exits. Case presentation This case describes a 73-year-old African American male who presented with recurrent squamous cell carcinoma (SCCA of the esophagus who has a achieved complete remission for 24 months via endoscopic cryospray ablation. Conclusion Endoscopic cryo spray ablation warrants further investigation as a palliative treatment modality for esophageal cancer. This is the first reported case in the medical literature.

The purpose of the current study was to evaluate the impact of fractionation on the treatment outcome of radiation therapy for hypopharyngeal carcinoma. Thirty-six inoperable or operation-refused hypopharyngeal patients were treated with curative-intended radiation therapy between 1976 and May 2001. Seventeen patients were treated with conventional radiation therapy, 1.8-2.0 Gy per fraction, totaling 64.0 Gy (conventional fractionation (CF) group), and 19 were treated with hyperfractionated radiation therapy, 1.2 Gy per fraction, totaling 74.4 Gy (hyperfractionation (HF) group). The radiation response of the two groups at the end of radiation therapy was almost the same. However, the 2-year local control rates of the HF and CF groups were 59.0% and 26.1% (p=0.012), respectively, a statistically significant differences. Moreover, multivariate analysis showed that HF was an independent prognostic factor for local control. Hyperfractionated radiation therapy was superior to conventional radiation therapy for local control. Local control of hypopharyngeal carcinoma correlated with laryngeal preservation, suggesting that hyperfractionated radiation therapy for hypopharyngeal carcinoma could be beneficial for patient quality of life (QOL).

By using chemotherapy combined with radiotherapy, significant improvements were achieved in treatment results of localized non-Hodgkin's lymphoma, intraoral cancer, and carcinoma of the maxillary sinus. Administering chemotherapy with radiation was given sumultaneously in the patients with intraoral cancer (BLM iv) and with carcinoma of the maxillary sinus (5-FU ia). In the patients with non-Hodgkin's lymphoma, chemotherapy (1 or 2 cycles of COPP) was administered and followed by radiotherapy. If radiation dose were reduced by about 50% in the intraoral cancer, 20% in carcinoma of the maxillary sinus, and 10% in non-Hodgkin's lymphoma, acute and/or chronic complications were within tolerable limits in this series of observations, although toxicity was dose-related for both chemotherapy and radiotherapy.

Basal cell carcinoma (BCC) is the most common cancer in the US population affecting approximately 2.8 million people per year. Basal cell carcinomas are usually slow-growing and rarely metastasize, but they do cause localized tissue destruction, compromised function, and cosmetic disfigurement. To provide clinicians with guidelines for the management of BCC based on evidence from a comprehensive literature review, and consensus among the authors. An extensive review of the medical literature was conducted to evaluate the optimal treatment methods for cutaneous BCC, taking into consideration cure rates, recurrence rates, aesthetic and functional outcomes, and cost-effectiveness of the procedures. Surgical approaches provide the best outcomes for BCCs. Mohs micrographic surgery provides the highest cure rates while maximizing tissue preservation, maintenance of function, and cosmesis. Mohs micrographic surgery is an efficient and cost-effective procedure and remains the treatment of choice for high-risk BCCs and for those in cosmetically sensitive locations. Nonsurgical modalities may be used for low-risk BCCs when surgery is contraindicated or impractical, but the cure rates are lower.

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

Purpose: To analyze the results obtained in a prospective group of patients with basal or squamous cell skin carcinomas of the face treated by high-dose-rate (HDR) brachytherapy via custom-made surface molds. Methods and Materials: A total of 136 patients with basal or squamous cell carcinomas of the face were treated between March 1992 and March 1997 by surface molds and HDR brachytherapy with iridium-192. Nineteen patients were treated with standard Brock applicators and 117 patients with custom-made polymethyl methacrylate applicators, built over a plaster mold obtained of the patient's face. Minimum dose administered to the tumor was 6000 to 6500 cGy in 33 to 36 fractions at 180 cGy/fraction in lesions of up to 4 cm. Lesions greater than 4 cm were boosted up to 7500-8000 cGy after a 3-week pause. Results: With the custom-made surface molds, the dose distribution was uniform in the surface of the skin and at 5 mm depth in the whole area of the applicator. Differences between the areas of maximum and minimum dose at this depth never reached values higher than 5% of the prescribed dose. At the edges of the custom-made molds dose gradient was sharp, with the detected dose at 5 mm from the applicator being negligible. All the patients were complete responders. There were 3 local recurrences, 1/73 patients treated for primary tumor and 2/63 patients treated for recurrent tumor. Actuarial local control at 5 years for all patients was 98%, for those patients with primary tumors 99%, and for recurrent patients 87%. The treatment tolerance was excellent in all cases. No severe, early, or late, complications were detected. Conclusions: Radiotherapy is a highly effective treatment of skin carcinomas of the face. Custom-made molds, to be used in conjunction with HDR brachytherapy equipment, make possible a uniform dose distribution, with a sharp dose gradient in the limits of applicators. Custom-made surface molds are easy and safe to use, and they fit very accurately for

Idiopathic granulomatous lobular mastitis (IGLM) is a rare chronic inflammatory disease of the breast with obscure etiology that mimics invasive carcinoma both clinically and radiologically. The treatment of IGLM remains controversial. The aim of proper management is to use a combination of medical and surgical treatment of this benign condition to achieve a good cosmetic result and low recurrence rate. A retrospective analysis of 19 patients with IGLM is performed based on the findings of clinical, radiological, and pathological examinations. The results of two treatments are presented: medical treatment with oral corticosteroids, and consecutive surgical excision after a follow-up period of 20 months (range, 6-75 months). The majority of patients treated in this paper were young (mean, 34 years) parous women with a history of hormonal medication use. The main clinical finding is large, irregular, and painful mass. Hypoechoic lobulated, irregular tubular or oval shaped masses had been imaged by ultrasound. Mammographic findings were an ill-defined mass, enlarged axillary lymph nodes, asymmetric density, and architectural distortion. Diagnoses of IGLM had been established by cytological or histological examination. Symptoms subside and inflammatory changes regressed with medical treatment. The remaining lesions were excised by consecutive breast conserving surgery. The disease recurred in one patient during the follow-up period. IGLM is an inflammatory breast disease found in young women who present with a large painful irregular mass, which mimics carcinoma, as a physical change. Breast imaging modalities are not helpful to differentiate IGLM from invasive cancer. The correct diagnosis is established by cytological or histological examination. Medical treatment with corticosteroids provides significant regression of the inflammatory disease, allowing more conservative surgery. Consecutive surgical excision of the remaining lesions with good cosmetic results

We investigated the contribution of subsequent therapy for advanced hepatocellular carcinoma refractory or intolerant to sorafenib. Further, we investigated the impact of sorafenib on overall survival using individual data. We reviewed the medical records of patients with advanced hepatocellular carcinoma treated with sorafenib. Survival after sorafenib treatment and overall survival were defined as the time when we discovered that patients were either refractory or intolerant to sorafenib and the period from the start of sorafenib treatment, respectively, until death during the study. We compared patients’ prognoses according to their subsequent treatment as follows: group A, therapies targeting intrahepatic lesions; group B, systemic therapies alone; group C, no subsequent therapy. We used linear regression analysis to determine whether there was an association with survival after sorafenib treatment and with overall survival. Of 79 patients, 63 (79.7 %) received one or more subsequent therapies (44 and 19 patients in groups A and B, respectively). The five patients who survived more than two years after sorafenib treatment was discontinued responded to therapies targeting intrahepatic lesions. The median survival times of groups A, B, and C were 11.9 months, 5.8 months, and 3.6 months, respectively. Multivariate analysis revealed that group A, Child-Pugh score, serum α-fetoprotein level, and cause of failure of sorafenib treatment were independent prognostic factors for survival after sorafenib treatment. Individual survival after sorafenib treatment correlated highly with overall survival. Targeting intrahepatic lesions may be useful for treating patients with advanced hepatocellular carcinoma patients after sorafenib treatment is discontinued.

Hepatocellular carcinoma (HCC) is a common cause of cancer mortality. Hepatitis B and C viruses, aflatoxin and alga toxin in the contaminated drinking water are the major etiological factors. Rapidly progressing medical imaging has resulted in the improved treatment results. Surgical resection has a major role for influencing prognosis of HCC. Local cancer therapies based on the advances in early diagnosis are progressing rapidly. Multimodality combination and sequential treatment has proved effective, unfortunately systemic chemotherapy for HCC remains disappointed. All of these have resulted in the improved prognosis of HCC.

From 1966 to 1981, 47 patients with a diagnosis of anal carcinoma were irradiated. This group was composed of 23 males and 24 females, with age ranging from 38 to 84 years (average 64.4 years). Five patients were treated preoperatively and 34 were treated definitively with cancericidal doses of irradiation. Acute radiation reactions requiring a rest-break were noted in 28% of patients, but all were managed as outpatients without untoward chronic sequelae. Chronic complications were noted in 13 patients, including two patients who required colostomy for severe anal stenosis and two who required A-P resection for large painful ulcers. Twenty-eight of 35 patients (80%) treated with irradiation alone have remained locally controlled without further treatment. An additional four have been salvaged by surgery. Only three patients had interstitial implants as part of their treatment course. Actuarial survival at five years for the N/sub 0/ patients and the group as a whole are 95.6 and 79.3%, respectively. It is concluded that external beam irradiation alone, properly fractionated to cancericidal doses, can control anal carcinoma with acceptable morbidity rates and without the use of either chemotherapy or interstitial implants in most cases. There is also a strong correlation suggesting that anal intercourse and male homosexuality play a significant role in the etiology of this disease.

Endometrial carcinoma is the most common gynaecologic malignancy in industrialised countries and the incidence is still rising. Primary treatment is based on preoperative risk classification and consists in most cases of hysterectomy with bilateral salpingo-oophorectomy. In patients with serous and clear cell histology a complete surgical staging is mandatory. However, in routine clinical practice final histology regularly does not correspond with the preoperative histological diagnosis. This results in both over and under treatment. The aim of this multicentre, prospective cohort study is to select a panel of prognostic biomarkers to improve preoperative diagnosis of endometrial carcinoma in order to identify those patients that need extended surgery and/or additional treatment. Additionally, we will determine whether incorporation of cervical cytology and comorbidity could improve this preoperative risk classification. All patients treated for endometrial carcinoma in the participating hospitals from September 2011 till December 2013 are included. Patient characteristics, as well as comorbidity are registered. Patients without preoperative histology, history of hysterectomy and/or endometrial carcinoma or no surgical treatment including hysterectomy are excluded. The preoperative histology and final pathology will be reviewed and compared by expert pathologists. Additional immunohistochemical analysis of IMP3, p53, ER, PR, MLH1, PTEN, beta-catenin, p16, Ki-67, stathmin, ARID1A and L1CAM will be performed.

Purpose: The purpose of this study was to develop a radiation therapy (RT) contouring atlas and recommendations for women with postoperative and locally advanced vulvar carcinoma. Methods and Materials: An international committee of 35 expert gynecologic radiation oncologists completed a survey of the treatment of vulvar carcinoma. An initial set of recommendations for contouring was discussed and generated by consensus. Two cases, 1 locally advanced and 1 postoperative, were contoured by 14 physicians. Contours were compared and analyzed using an expectation-maximization algorithm for simultaneous truth and performance level estimation (STAPLE), and a 95% confidence interval contour was developed. The level of agreement among contours was assessed using a kappa statistic. STAPLE contours underwent full committee editing to generate the final atlas consensus contours. Results: Analysis of the 14 contours showed substantial agreement, with kappa statistics of 0.69 and 0.64 for cases 1 and 2, respectively. There was high specificity for both cases (≥99%) and only moderate sensitivity of 71.3% and 64.9% for cases 1 and 2, respectively. Expert review and discussion generated consensus recommendations for contouring target volumes and treatment for postoperative and locally advanced vulvar cancer. Conclusions: These consensus recommendations for contouring and treatment of vulvar cancer identified areas of complexity and controversy. Given the lack of clinical research evidence in vulvar cancer radiation therapy, the committee advocates a conservative and consistent approach using standardized recommendations.

Combined radiological and chemical treatment of carcinomas of the anus

International Nuclear Information System (INIS)

Schuck, U.

1988-01-01

A combination of radiotherapy and chemotherapy has proved effective and the toxic reactions to this treatment generally remain within tolerable limits, as there is no need to inflict major wounds and the anal functions can largely be maintained. The tumour remission seen here is more rapid and more radical than that achieved by the simple use of irradiation. This means that the radiation dose may safely be reduced without thereby marring the success of treatment. Cytostatic drugs alone show no great effectiveness against anal carcinomas and are beneficial only in connection with radiation treatment. Acute local reactions were observed in all patients, while the delayed effects seen following surgery or radiotherapy as the sole method of treatment failed to occur here. The main drawback of radiochemical treatment are hematological side-effects in the form of bone marrow depression. (VHE) [de

Neoadjuvant treatment intensification or adjuvant chemotherapy for locally advanced carcinoma rectum: The optimum treatment approach remains unresolved.

2015-12-01

Rectal carcinoma [RC] is often managed with preoperative radiotherapy or radio-chemotherapy followed by total mesorectal excision (TME). Efforts are being made to improve outcome by intensifying the preoperative treatment. However, the optimum therapy remains unclear. There is ongoing controversy regarding the optimum radiation dose, chemotherapy regimen and schedule. In addition there exists growing disagreement regarding the role of adjuvant chemotherapy after neoadjuvant radiation or chemoradiation. We reviewed the recent land mark trials to find a road map in the management of locally advanced rectal carcinoma. Preoperative short course radiotherapy has long been proven to improve local disease control. The initial trials with long course chemoradiotherapy, comparing short course radiotherapy have shown to increase local control and pathological complete response rates. Since then treatment intensification of this neoadjuvant schedule has been tried by many researchers. But initial results of these treatment intensification trials, show no significant benefit and are associated with increased toxicity. There is an unmet need to stratify patients depending on risk to assign them to long course chemoradiotherapy or short course radiotherapy. Current evidence does not support the use of adjuvant chemotherapy in patients who were treated with preoperative (chemo)radiotherapy. Preoperative radiotherapy appears to improve disease control with favorable toxicity profile and there is very little to choose between long course chemoradiotherapy and short course radiotherapy. However, long course chemoradiotherapy may be beneficial for patients with high risk features like positive circumferential resection margin [CRM] and extramural spread of >5mm. There is no role for adjuvant chemotherapy in patients who were treated preoperative (chemo)radiotherapy. Copyright © 2015 The Authors. Production and hosting by Elsevier B.V. All rights reserved.

Improving clinical trial design for hepatocellular carcinoma treatments

Directory of Open Access Journals (Sweden)

Robert G. Gish

2011-12-01

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

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)

A report is given on 160 patients suffering from ovarian carcinomas the stages which were exactly determined by TNM classification. 32 patients had tumors of the stages T1-T3, 128 patients had tumors of the stage T4. All T3 subgroups showed favorable results after radical surgery and a postoperative combination of radiotherapy and selective cytostatic chemotherapy. The therapy plans including radiotherapy had more advantages than those without radiotherapy. Furthermore, the cytostatic treatment was more successful after a chemotherapy resistance test than after blind administration of cytostatic drugs. (orig.) [de

The comparison between effect of chemoradiation with weekly cisplatin with or without celecoxib in treatment of nasopharyngeal carcinoma: A phase III clinical trial

2009-07-01

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

Osseous oligometastases from thymic carcinoma: a case report suggesting the effectiveness of palliative-intent radiotherapy treatment.

2016-01-01

Oligometastasis, a recently proposed concept, is defined as an intermediate state of cancer, between localized and systemic disease, that may be well controlled by local ablative treatment. Thymic carcinoma is a rare cancer with a poor prognosis. A definitive management approach has yet to be confirmed by a high level of evidence. We present the case of a 41-year-old female who underwent curative-intent surgery for a stage III squamous cell carcinoma of the thymus. Bone metastases were detected 1 year later by magnetic resonance imaging. These were treated with palliative-intent radiotherapy. Disease progression has not been observed in more than 15 years since the achievement of complete radiological remission. The treatment outcomes in this and other reported cases suggest that some patients with oligometastatic thymic carcinoma may achieve prolonged survival or even cure with low-dose radiotherapy delivered to the metastases.

The purpose of this study was to assess the anatomic and functional outcomes and compare the voice quality in patients affected by T1a glottic carcinoma treated with curative intent with radiotherapy or laser cordectomy. Fifty-seven cases were analysed: 27 after curative radiotherapy and 30 after laser cordectomy. All patients were studied with videolaryngostroboscopy, voice analysis by narrow spectrogram, and vocal parameters (Jitter, Shimmer, noise/harmonic ratio, and diplophonia). Videolaryngostroboscopy showed severe glottic inadequacy in 25% of cases treated with radiation and insufficient compensation 'ventricular band' or 'with arytenoid hyperadduction' in 65% of cases after surgery. Severe dysphonia on the electro-acoustic analysis of voice was observed in 25% of cases after radiation and 70% after laser (p<0.001). Fundamental frequency and vocal parameters showed more favourable results in the radiation group (p<0.001). Voice assessment showed better results after radiotherapy compared with laser cordectomy. Voice outcome should be carefully considered in the treatment decision for T1 glottic carcinoma.

Radiotherapy of bronchogenic carcinoma

Heilmann, H.P.

1982-01-01

Radiotherapy of branchogenic carcinoma comprises; palliative treatment, postoperative or pre-operative radiotherapy, radiotherapy as part of a combination of chemotherapy and radiotherapy of small cell carcinoma and curative radiotherapy of non-operable non-small cell carcinoma. Atelectasis and obstruction are indications for palliative radiotherapy. Postoperative radiotherapy is given only in cases of incomplete resection or mediastinal metastases. In the treatment of small cell carcinoma by combined irradiation and chemotherapy the mediastinum and primary tumour are irradiated, generally after chemotherapy, and the C.N.S. receives prophylactic radiotherapy. Curative radiotherapy is indicated in cases of non-operable small cell carcinoma. Irradiation with doses of 60-70 Gy produced 5-years-survival rates of 10-14% in cases classified as T 1 -T 2 N 0 M 0 . (orig.) [de

To investigate the effectiveness of hyperthermia in the preoperative combined treatment of radiation, chemotherapy and hyperthermia for rectal carcinoma, two groups were compared. Group A consisted of 18 patients in whom hyperthermia, radiation and chemotherapy were performed. Group B consisted of 18 patients in whom only chemotherapy and radiation were performed. The total dose of radiation in both of the two groups was 40.5 Gy, and a radiation field covering the whole pelvis was used. Hyperthermia was performed using 8 MHz radiofrequency waves (Thermotron RF8, Yamamoto Vinyter, Japan), and tumors were heated at about 42 degrees C for 50 minutes. Hyperthermia was repeated five times during the preoperative treatment. Chemotherapy was performed by giving 5-fluorouracil suppositories to a total dose of 3400 mg. Mean tumor reduction rates on barium enema were 31.8% in group A and 18.2% in group B. The difference was statistically significant. The result of the histological assessment of tumor necrosis showed that there was a significantly higher degree of necrosis in group A than in group B. These results showed that the addition of hyperthermia enhanced tumor necrosis. It was concluded that the addition of hyperthermia would be an effective preoperative treatment of rectal carcinoma.

Currently available curative options, such as surgery and transplantation, are not available to patients with advanced stages of disease. Among the potential new treatments being investigated are microRNA (miRNA-based therapies. A number of preclinical studies have reported antitumor activities of miRNA mimics or anti-miRNA molecules. Optimal in vivo delivery of miRNA molecules is crucial to their action. To this end, significant progress has been made in the development of nanoparticles for in vivo delivery of miRNA molecules. Delivery of these molecules, alone or in combination with other drugs, promises to open new possibilities for therapeutic approaches to hepatocellular carcinoma.

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

The efficacy of adjuvant radiochemotherapy (RCT) in patients with advanced stage head and neck carcinoma has been proven in prospective randomized trials. However, these trials focused on different head and neck sites. Specific analyses for treatment effects in squamous cell carcinoma of the oral cavity (OSCC) are missing. We evaluated our experiences with adjuvant concomitant RCT in advanced OSCC to compare the results with other treatment schemes using adjuvant RCT. A total of 183 patients with OSCC of UICC stages II-IVb were reviewed retrospectively. All patients were treated with radical surgery followed by adjuvant, conventional fractionated concomitant RCT using carboplatin. Overall survival was plotted by Kaplan-Meier analysis. Prognostic factors were identified through univariate and multivariate analysis. Univariate analysis showed a significant impact of T, N, and UICC stage, histopathologic grading, surgical margins, extracapsular spread (ECS), and lymphangiosis carcinomatosa on overall survival (Table 3). Patients with stage IVa had a higher 5-year overall survival rate (42.8%) than patients with stage IVb (25.0%) (Figure 1). The differences were significant in multivariate analysis (p = 0.033) (Table 4). Adjuvant concomitant RCT is an effective treatment in patients with advanced stage OSCC. However, it remains unclear, which patients should be treated with adjuvant RCT. For patients with stage IVb, adjuvant RCT yields poor results. Prospective randomized trials are needed to confirm which patients should be treated with adjuvant RCT. (orig.)

This study describes the experience with hypofractionated radiation therapy of squamous cell carcinoma and melanoma in dogs and cats. A total dose of 32-48 Gray (Gy) was delivered once a week in 8 Gy fractions. 34 animals in which a complete surgical excision was impossible were treated. There was no tumor detectable macroscopically in 14 patients at the beginning of radiation therapy. In 20 animals the median volume of the tumor was 9.9 cm3. The median survival times and the local tumor control of squamous cell carcinoma of the oral and nasal cavities and of the body are comparable to results which were reached with a Monday-Wednesday-Friday scheme. For the treatment of Melanoma the hypofractionated radiation therapy is first choice. There are no significant side effects. Late side effects did not occur. 88% of the owners are satisfied with this kind of treatment and would choose it again.

To investigate the accuracy of Medical Benefit Schedule (MBS) item numbers to identify treatments for basal cell carcinomas (BCC) and squamous cell carcinomas (SCC). We linked records from QSkin Study participants (n=37,103) to Medicare. We measured the proportion of Medicare claims for primary excision of BCC/SCC that had corresponding claims for histopathology services. In subsets of participants, we estimated the sensitivity and external concordance of MBS item numbers for identifying BCC/SCC diagnoses by comparing against 'gold-standard' histopathology reports. A total of 2,821 (7.6%) participants had 4,830 separate Medicare claims for BCC/SCC excision; almost all (97%) had contemporaneous Medicare claims for histopathology services. Among participants with BCC/SCC confirmed by histology reports, 76% had a corresponding Medicare claim for primary surgical excision of BCC/SCC. External concordance for Medicare claims for primary BCC/SCC excision was 68%, increasing to 97% when diagnoses for intra-epidermal carcinomas and keratoacanthomas were included. MBS item numbers for primary excision of BCC/SCC are reasonably reliable for determining incident cases of keratinocyte skin cancers, but may underestimate incidence by up to 24%. Medicare claims data may have utility in monitoring trends in conditions for which there is no mandatory reporting. © 2015 Public Health Association of Australia.

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

We have been applying superselective intra-arterial chemotherapy (SIC) by using the Seldinger technique as the treatment strategy for maxillary sinus carcinoma since 1998 in combination with radiotherapy and surgery. SIC allows delivery of high-dose anticancer drugs to the target tumor at high concentrations through its feeding vessel with few adverse effects by neutralizing and limiting the toxic effects of cisplatin (CDDP) within an acceptable range. We studied the effect of primary treatment and adverse events in 40 patients with squamous cell carcinoma of the maxillary sinus who underwent high-dose SIC combined with radiotherapy in our department between 1998 and 2008. The patients were 30 men and 10 women aged 43 to 75 years (median, 61 years). All carcinomas were advanced and graded as T3 in 17, T4 in 23, and N+ in 8. Some of the carcinomas reached the skull base or extended deep into the orbit. SIC was performed using the Seldinger technique from the femoral artery. Total CDDP dose was 200-300 mg/m 2 (mean, 210 mg/m 2 ). All vessels used for the treatment were those branching from the external carotid arteries; those from internal carotid arteries were not used for intra-arterial infusion. Following arterial infusion chemotherapy, systemic administration of 800 mg 5-fluorouracil (FU) was started on Day 2. Simultaneous radiotherapy was started on Day 2 at a dose of 2 Gy with a goal of increasing up to 60 Gy. Patients enrolled in this treatment arm received two courses of chemotherapy at 1- to 2-week intervals, along with a total dose of 60 Gy of radiotherapy from 1998 to 2007. Since 2008, two courses of SIC with the Seldinger technique, based on the results of postoperative pathological examination, and curative radiation at 60 Gy became the preferred basic treatment strategy irrespective of tumor size, and evaluation of treatment response at the level of 40 Gy was abandoned. For residual or recurrent carcinoma, we took a ''wait and see'' approach and

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

This is a retrospective analysis of 148 patients with histologically proven carcinoma of the cervix, stage III, treated with irradiation. All patients received external irradiation with cobalt 60 followed by intracavitary radium application. The median age was 55 years. Squamous cell carcinoma was found in 96.5% of the cases. The 8-year actuarial survival rate was 41%. Bilateral parametrial invasion proved to be a strong prognostic factor. Patients with unilateral disease had a survival rate of 43% whereas in those with bilateral involvement it was only 15% (P less than 0.005). The total pelvic failure rate was 29.5%. The overall incidence of distant metastasis was 11%. The complication rate (minor and major complications) was high, with vaginal stenosis (22.5%), proctitis (21.5%), cystitis (13.5%), and fistulae (4%) occurring in 33, 32, 20, and 6 patients, respectively. New treatment modalities are urgently needed for advanced carcinoma of the cervix. Bilateral parametrial involvement is an unfavorable prognostic factor and this should be kept in mind when designing new protocols

The goal of the current study was to understand and document contemporary treatment approaches in the management of ductal carcinoma in situ (DCIS). An original questionnaire was designed to assess radiation oncologists' management of breast carcinoma, including 26 questions specifically addressing DCIS. A postal survey was conducted of members of the American and European Societies of Therapeutic Radiology and Oncology. The results of 702 responses from North America were compared with 435 responses from Europe, to determine treatment recommendations and variability by type of institution and geographic region. There were strong correlations between the grade of DCIS and/or the margin status and the use of radiotherapy (RT; P variations in physician recommendations for tamoxifen (P < 0.001), but not in the tendency to recommend RT. North American academic physicians were less likely to recommend RT for favorable DCIS than nonacademic physicians (P < 0.01). There were marked differences in physician opinions regarding the management of DCIS, with significant international differences in patterns of care. The survey quantified and highlighted areas of agreement and controversy regarding the use of RT and tamoxifen in the management of DCIS. It provided support for large international trials to evaluate the optimal management of DCIS in the areas identified as most controversial.

Objective: To investigate the clinical characteristics and treatment of primary parotid squamous cell carcinoma through 16 patients. Methods: Sixteen such patients treated in our hospital from 1984 to 2005 were analyzed retrospectively. There were T1 2 patients, T2 and T3 5 patients each and T4 4. Ten patients had NO, and 6 N + lesions. Six patients were treated by monotherapy, ie-mono group (surgery alone or radiotherapy alone), the other 10 patients by surgery combined with postoperative radiotherapy. Results: The overall neck metastastic lymph nodes was observed in 12 patients (75%). The 3- and 5-year local control, overall survival and disease-free survival for the whole group was 45% and 30%, 58% and 58%; 36% and 27%, respectively. The 5-year survival for T1-T2 and T3-T4 patients was 100% and 29% (χ 2 =4.50, P=0.034), respectively. The 3-year overall survival of NO and N + patients was 80%, and 20% (χ 2 =8.70, P=0.003), with a disease-free survival of 54% and 0 (χ 2 =9.83, P=0.002), respectively. Conclusions: The choice of suitable treatment for locally advanced primary parotid squamous cell carcinoma is surgery plus postoperative radiotherapy. Prophylactic ipsilateral neck irradiation is necessary e- ven for N0 patients for the sake of high risk of neck node metastasis. (authors)

Purpose: To determine the role of laparoscopic lymphadenectomy (pelvis ± para-aortic nodes) and laparoscopic hysterectomy in cervical cancer compared to 'classic radical surgery' in patients undergoing surgery in comparison with modern imaging in patients treated with radiotherapy alone.Materials and methods: The limitations of modern imaging are presented as well as how complication rates can be increased when classic laparotomy is followed by radiation therapy.Laparoscopic procedures are described with particular emphasis on how to provide information on lymph node metastases with the risk of overlooking microscopic involvement. A number of clinical experiences are cited to illustrate this problem and show how treatment approaches can be adapted.Results: The role of laparoscopy is evaluated according to different clinical situations and treatment protocols emphasizing the possibilities offered by this method to the radiotherapist. Conclusion: When developing laparoscopic techniques for the management of cervical carcinoma, caution must be exercised to ensure that these techniques are not detrimental to the prognosis.

In a majority of the cases, HCC is associated with the underlying chronic liver disease, and it is diagnosed in advanced stage of disease when curative treatment options are not applicable. Sorafenib is a treatment of choice for patients with performance status 1 or 2 and/or macrovascular invasion or extrahepatic spread, and regorafenib is the only systemic treatment found to provide survival benefit in HCC patients progressing on sorafenib treatment. Other drugs tested in different trials failed to demonstrate any benefit. Disappointing results of numerous trials testing the efficacy of various drugs indicate that HCC has low sensitivity to chemotherapy that is in great part caused by multidrug resistance. Immunotherapy for HCC is a new challenging treatment option and involves immune checkpoint inhibitors/antibody-based therapy and peptide-based vaccines. Another challenging approach is microRNA-based therapy that involves two strategies. The first aims to inhibit oncogenic miRNAs by using miRNA antagonists and the second strategy is miRNA replacement, which involves the reintroduction of a tumor-suppressor miRNA mimetic to restore a loss of function.

Wolfgang Hagmann

2010-09-01

Full Text Available Gemcitabine is widely used as first-line chemotherapeutic drug in the treatment of pancreatic cancer. Our previous experimental chemotherapy studies have shown that treatment of human pancreatic carcinoma cells with 5-fluorouracil (5-FU alters the cellular transporter expression profile and that modulation of the expression of multidrug resistance protein 5 (MRP5; ABCC5 influences the chemoresistance of these tumor cells. Here, we studied the influence of acute and chronic gemcitabine treatment on the expression of relevant uptake and export transporters in pancreatic carcinoma cells by reverse transcription-polymerase chain reaction (RT-PCR, quantitative RT-PCR, and immunoblot analyses. The specific role of MRP5 in cellular gemcitabine sensitivity was studied by cytotoxicity assays using MRP5-overexpressing and MRP5-silenced cells. Exposure to gemcitabine (12 nM for 3 days did not alter the messenger RNA (mRNA expression of MRP1, MRP3, MRP5, and equilibrative nucleoside transporter 1 (ENT1, whereas high dosages of the drug (20 µM for 1 hour elicited up-regulation of these transporters in most cell lines studied. In cells with acquired gemcitabine resistance (up to 160 nM gemcitabine, the mRNA or protein expression of the gemcitabine transporters MRP5 and ENT1 was upregulated in several cell lines. Combined treatment with 5-FU and gemcitabine caused a 5- to 40-fold increase in MRP5 and ENT1 expressions. Cytotoxicity assays using either MRP5-overexpressing (HEK and PANC-1 or MRP5-silenced (PANC1/shMRP5 cells indicated that MRP5 contributes to gemcitabine resistance. Thus, our novel data not only on drug-induced alterations of transporter expression relevant for gemcitabine uptake and export but also on the link between gemcitabine sensitivity and MRP5 expression may lead to improved strategies of future chemotherapy regimens using gemcitabine in pancreatic carcinoma patients.

Preliminary results of transarterial Rhenium-188 HDD Lipiodol in treatment of inoperable primary hepatocellular carcinoma

Full text: In this paper we present our early experience with a new radio-conjugate, namely rhenium-188 HDD Lipiodol (Re-188 lipiodol). Imported radiopharmaceuticals are generally expensive, particularly for developing countries. A Tungsten (W-188-Re 188) generator obtained from ORNL (Oak Ridge National Laboratory, Tennessee, USA) allows us on-site production of a beta emitting therapeutic isotope (Re-188) for up to 6 months from a single generator. The objectives of this study were to establish the safety of trans-arterial Re-188 lipiodol in patients with inoperable HCC, and determine the adverse effects and efficacy for this radio-conjugate treatment in a multi-center study of patients with advanced HCC. A multi-center study was sponsored by the International Atomic Energy Agency (Vienna) to assess the safety and efficacy of trans-arterial Re-188 HDD conjugated lipiodol (radio-conjugate) in the treatment of patients with inoperable hepatocellular carcinoma (HCC), The radio-conjugate was prepared by using a HDD (4-hexadecyl 1-2, 9, 9-tetramethyl-4, 7-diaza-1, 10-decanethiol) kit developed in Korea, and lipiodol. Over a period of eighteen months seventy patients received at least one treatment of radio-conjugate. Some patients were re-treated if there was no evidence of disease progression. The level of radio-conjugate administered was based on radiation-absorbed dose to critical normal organs, calculated following a 'scout' dose of radio-conjugate. The organs at greatest risk for radiation toxicity are the normal liver, the lung and the bone marrow. A specially designed spreadsheet was used to determine maximum tolerated activity (MTA), defined as the amount of radioactivity calculated to deliver no more than 12 Gray (Gy) to lungs, or 30 Gy to liver, or 1.5 Gy to bone marrow. These doses have been found to be safe in multiple trials using external beam therapy and systemically administered radiopharmaceuticals. Patients were followed for at least twelve weeks

Between 1971 and 1976, 33 patients with adenocarcinoma of the prostate T2-T4 and without evidence of distant metastases have been treated with high energy radiotherapy 50-70Gy given to the primary tumour. 72% showed local response to the treatment. Actuarial 5 years survival (uncorrected) for patients primarily treated with radiotherapy was 52%, but for patients who had earlier received oestrogens, only 16%. The results in terms of local control as well as survival were best for category T2 and T3 patients who had not previously received hormone treatment. The response rate was better for moderately differentiated carcinomas than for poorly differentiated carcinomas.

A 59-year-old woman was admitted to the hospital with a one-month history of hemoptysis, generalized fatigue, and a high fever. A chest X-ray film obtained on admission showed a massive right-sided pleural effusion. Examination of an aspirate showed a high level of amylase, and bacteria that were the same as oral bacteria. Closed drainage yielded ichorous pus and food residues, which led us to the diagnosis of empyema caused by esophageal perforation. Esophagography and fiberoptic esophagoscopy revealed that an esophagobronchial fistula related to an advanced esophageal carcinoma had caused the empyema. Surgical resection was done, and the patient was alive at the time of this writing, 7 months after she was first treated. Esophageal carcinoma is sometimes accompanied by esophagobronchial fistula. Patients with this condition usually have severe respiratory symptoms; those presenting with empyema are rare. Esophageal carcinoma must be carefully ruled out as the cause of empyema.

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 evaluate survival and functional results of the treatment of carcinomas of the vallecula using surgery, irradiation, and interstitial brachytherapy. Methods and Materials: Between 1990 and 1998, 36 patients with squamous cell carcinoma of the vallecula were treated with horizontal supraglottic functional laryngectomy, external beam radiotherapy (median dose 54 Gy), and additional interstitial brachytherapy (median dose 16 Gy). Results were compared with a previous series of 22 patients treated without brachytherapy. Results: The median follow-up was 44 months. The 5-year actuarial overall survival rate was 61.3%. The 5-year specific survival rate was 86%, with 2 local failures (local control rate 94.4%) and 4 isolated distant metastases. Ten patients developed a second primary. The overall survival was 34% for 22 patients previously treated without brachytherapy. Severe toxicities occurred in 9 patients: death (related to larynx edema or inhalation, n=1), soft tissue necrosis (n=1), aspiration pneumonia (n=1), mandibular necrosis (n=2), pharyngocutaneous fistula (n=2), and laryngeal edema (n=2). All the patients fed orally with no definitive gastrostomy or tracheotomy. Conclusion: Additional brachytherapy for vallecula carcinoma seems to improve locoregional control and overall survival dramatically. Functional results were also excellent. To our knowledge, this original therapeutic schedule has never been previously described

The incidence of post-operative complications and treatment results of 60 cases of hypopharynx carcinoma receiving laryngo-pharyngo-esophagectomy followed by reconstruction with jejunum after chemoradiotherapy (CRT) from 1997 to 2006 in 6 hospitals was analyzed. The overall complication rate was 57%. There were 3 cases with carotid artery rupture (5%), 4 with jejunum necrosis (6%), 6 with major salivary fistula (10%), 8 with minor salivary fistula (13%), 8 with abscess alone (13%), 3 with trachea stoma necrosis (5%), and 3 with skin flap necrosis (5%). The death rate due to surgical complications was 3% (2/60). When the cases were divided into two groups, namely the cases with fistula and the cases without fistula, the number of days that permitted drinking was 18.1 in the latter and 81.8 in the former. The 5-year overall survival rate among all cases was 37%. We found that salvage surgery after CRT was effective for recurrent cases. These findings suggest that reconstruction with jejunum is a suitable type of operation with better surgical results. Care is required to reduce the incidence of post-operative complications.

Despite improvements in the management of liver cancer, the survival rate for individuals with hepatocellular carcinoma (HCC) remains dismal. The survival benefit of systemic chemotherapy for the treatment of liver cancer is only marginal. Although the reasons for treatment failure...... are multifactorial, intrinsic resistance to chemotherapy plays a primary role. Here, we analyzed the expression of 377 multidrug resistance-associated genes in two independent cohorts of patients with advanced hepatocellular carcinoma, with the aim of finding ways to improve survival in this poor-prognosis cancer...

Full Text Available Jörg Trojan, Oliver Waidmann Medizinische Klinik 1, Universitätsklinikum Frankfurt, Germany Abstract: Sorafenib is still the only systemic drug approved for the treatment of advanced hepatocellular carcinoma (HCC. In recent years, several investigational agents mainly targeting angiogenesis failed in late-phase clinical development due to either toxicity or lack of benefit. Recently, data of the RESORCE trial, a placebo-controlled Phase III study that evaluated the efficacy and safety of regorafenib in patients with HCC and documented disease progression after systemic first-line treatment with sorafenib, were presented at the ESMO World Congress on Gastrointestinal Cancer, 2016. Regorafenib treatment resulted in a 2.8-month survival benefit compared to placebo (10.6 months vs 7.8 months. Side effects were consistent with the known profile of regorafenib. The approval of regorafenib for this indication is expected in 2017. Further candidate agents in Phase III evaluation for second-line treatment of patients with HCC are the MET inhibitors tivantinib and cabozantinib, the vascular endothelial growth factor receptor-2 antibody ramucirumab, and the programmed death receptor-1 (PD-1 blocking antibody pembrolizumab. Furthermore, results from two first-line trials with either the tyrosine kinase inhibitor lenvatinib or the PD-1 antibody nivolumabin in comparison to sorafenib are awaited in the near future and might further change the treatment sequence of advanced HCC.

From 1965 through 1985, 85 patients with carcinoma of the nasopharynx were irradiated with curative intent at the Department of Radiation Therapy, Aichi Cancer Center Hospital. The observed 5-year survival rate was found to be 34 %. Local recurrence was observed in 15 cases, regional lymph node recurrence in 10 cases, local and regional lymph node recurrence in 2 cases and distant metastases in 24 cases. Most manifestations of recurrence appeared within 2 years after treatment. Local recurrence was often observed in the base of skull in patients in advanced stages of their disease (T 3 - 4). The likelihood of a distant metastasis was stronger in patients with a bilateral neck nodes metastases and/or a lower neck metastases. (author)

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

Metastatic renal cell carcinoma management

Directory of Open Access Journals (Sweden)

Flavio L. Heldwein

2009-06-01

Full Text Available PURPOSE: To assess the current treatment of metastatic renal cell carcinoma, focusing on medical treatment options. MATERIAL AND METHODS: The most important recent publications have been selected after a literature search employing PubMed using the search terms: advanced and metastatic renal cell carcinoma, anti-angiogenesis drugs and systemic therapy; also significant meeting abstracts were consulted. RESULTS: Progress in understanding the molecular basis of renal cell carcinoma, especially related to genetics and angiogenesis, has been achieved mainly through of the study of von Hippel-Lindau disease. A great variety of active agents have been developed and tested in metastatic renal cell carcinoma (mRCC patients. New specific molecular therapies in metastatic disease are discussed. Sunitinib, Sorafenib and Bevacizumab increase the progression-free survival when compared to therapy with cytokines. Temsirolimus increases overall survival in high-risk patients. Growth factors and regulatory enzymes, such as carbonic anhydrase IX may be targets for future therapies. CONCLUSIONS: A broader knowledge of clear cell carcinoma molecular biology has permitted the beginning of a new era in mRCC therapy. Benefits of these novel agents in terms of progression-free and overall survival have been observed in patients with mRCC, and, in many cases, have become the standard of care. Sunitinib is now considered the new reference first-line treatment for mRCC. Despite all the progress in recent years, complete responses are still very rare. Currently, many important issues regarding the use of these agents in the management of metastatic renal cancer still need to be properly addressed.

Transfer of intestine-derived diamines into tumour cells during treatment of Ehrlich-ascites--carcinoma-bearing mice with polyamine anti-metabolites.

Kallio, A; Nikula, P; Jänne, J

1984-01-01

Treatment of Ehrlich-ascites-carcinoma-bearing mice with methylglyoxal bis(guanylhydrazone) alone or in combination with 2-difluoromethylornithine greatly enhanced the transfer of intragastrically administered radioactive putrescine and cadaverine into the carcinoma cells. Difluoromethylornithine alone did not have any effect on the accumulation of intestine-derived diamines in the tumour cells. The frequently reported restoration of difluoromethylornithine-induced polyamine depletion on administration of methylglyoxal bis(guanylhydrazone) is in all likelihood attributable to a profound inhibition of intestinal diamine oxidase (EC 1.4.3.6), resulting in an enhanced entry of intestinal (bacterial) diamines into general circulation and finally into tumour cells.

1975-01-01

A selected group of 136 patients with Stage I squamous cell carcinoma of the cervix was treated in six naval hospitals during the period 1957--1965 using a three-stage combined radiation therapy and surgery protocol. Treatment consisted of two radium applications to the cervix, followed in 6 weeks by extraperitoneal lymphadenectomy. If the lymph nodes were tumor-negative, simple hysterectomy in 3 to 6 months completed the protocol. If the nodes were tumor-positive, a course of external pelvic irradiation was given with midline shielding. The incidence of positive nodes was 9.6 percent. Actuarial survival for all patients was 89.4 percent, comparable to the rate obtained by radical surgery or radiation alone. Postoperative and postradiation complications were minimal, with no urinary or bowel fistulas. There was no operative mortality

Purpose To assess the long-term outcome in 108 consecutive patients treated with no-touch multibipolar radiofrequency ablation (RFA) for hepatocellular carcinoma (HCC) that met the Milan criteria. Materials and Methods This retrospective study was approved by the ethical review board, and the need to obtain informed consent was waived. Between November 1, 2006, and December 31, 2011, 132 HCC tumors (diameter, 10-45 mm; 39 tumors ≥ 30 mm) in 108 consecutive patients (106 with cirrhosis) that met Milan criteria were treated with no-touch multibipolar RFA, which consisted of activating, in bipolar mode, three or four electrodes inserted just beyond the tumor margins. Follow-up was performed every 3 months for 2 years and every 6 months thereafter with computed tomographic or magnetic resonance imaging. Survival probabilities were computed by using the Kaplan-Meier method. Predictive factors of tumor progression and overall survival were assessed by using the Cox proportional hazard model. Results No technical failure occurred, and complete ablation was achieved for all the nodules. After a median of 40.5 months (range, 2-84 months) of follow-up, 3- and 5-year local and overall tumor progression-free survival were 96%, 94%, 52%, and 32%, respectively. Neither tumor diameter greater than 30 mm nor location abutting a large vessel were associated with local tumor progression. Tumor diameter greater than 30 mm was the only parameter predictive of overall tumor progression (P = .0036). Independent factors associated with shorter overall survival were Child-Pugh class B disease, age greater than 65 years, and platelet count of less than 150 g/L (P touch multibipolar RFA for HCC tumors that meet Milan criteria provides a high local tumor progression-free survival rate. An ongoing randomized trial might help to clarify the role of this new approach for the treatment of early HCC. (©) RSNA, 2016 Online supplemental material is available for this article. An earlier

Transarterial RAdioembolization versus ChemoEmbolization for the treatment of hepatocellular carcinoma (TRACE: study protocol for a randomized controlled trial

Full Text Available Abstract Background Hepatocellular carcinoma is a primary malignant tumor of the liver that accounts for an important health problem worldwide. Only 10 to 15% of hepatocellular carcinoma patients are suitable candidates for treatment with curative intent, such as hepatic resection and liver transplantation. A majority of patients have locally advanced, liver restricted disease (Barcelona Clinic Liver Cancer (BCLC staging system intermediate stage. Transarterial loco regional treatment modalities offer palliative treatment options for these patients; transarterial chemoembolization (TACE is the current standard treatment. During TACE, a catheter is advanced into the branches of the hepatic artery supplying the tumor, and a combination of embolic material and chemotherapeutics is delivered through the catheter directly into the tumor. Yttrium-90 radioembolization (90Y-RE involves the transarterial administration of minimally embolic microspheres loaded with Yttrium-90, a β-emitting isotope, delivering selective internal radiation to the tumor. 90Y-RE is increasingly used in clinical practice for treatment of intermediate stage hepatocellular carcinoma, but its efficacy has never been prospectively compared to that of the standard treatment (TACE. In this study, we describe the protocol of a multicenter randomized controlled trial aimed at comparing the effectiveness of TACE and 90Y-RE for treatment of patients with unresectable (BCLC intermediate stage hepatocellular carcinoma. Methods/design In this pragmatic randomized controlled trial, 140 patients with unresectable (BCLC intermediate stage hepatocellular carcinoma, with Eastern Cooperative Oncology Group performance status 0 to 1 and Child-Pugh A to B will be randomly assigned to either 90Y-RE or TACE with drug eluting beads. Patients assigned to 90Y-RE will first receive a diagnostic angiography, followed by the actual transarterial treatment, which can be divided into two sessions in case

Preclinical Characterization of a Novel Monoclonal Antibody NEO-201 for the Treatment of Human Carcinomas

Full Text Available NEO-201 is a novel humanized IgG1 monoclonal antibody that was derived from an immunogenic preparation of tumor-associated antigens from pooled allogeneic colon tumor tissue extracts. It was found to react against a variety of cultured human carcinoma cell lines and was highly reactive against the majority of tumor tissues from many different carcinomas, including colon, pancreatic, stomach, lung, and breast cancers. NEO-201 also exhibited tumor specificity, as the majority of normal tissues were not recognized by this antibody. Functional assays revealed that treatment with NEO-201 is capable of mediating both antibody-dependent cellular cytotoxicity (ADCC and complement-dependent cytotoxicity (CDC against tumor cells. Furthermore, the growth of human pancreatic xenograft tumors in vivo was largely attenuated by treatment with NEO-201 both alone and in combination with human peripheral blood mononuclear cells as an effector cell source for ADCC. In vivo biodistribution studies in human tumor xenograft-bearing mice revealed that NEO-201 preferentially accumulates in the tumor but not organ tissue. Finally, a single-dose toxicity study in non-human primates demonstrated safety and tolerability of NEO-201, as a transient decrease in circulating neutrophils was the only related adverse effect observed. These findings indicate that NEO-201 warrants clinical testing as both a novel diagnostic and therapeutic agent for the treatment of a broad variety of carcinomas.

Radiochemotherapy is the main treatment for patients with squamous cell carcinoma of the anal canal. Anaemia is reported to have adverse effect on survival in cancer patients. The aim of the study was to evaluate the influence of anaemia on radiochemotherapy treatment outcome in patients with squamous cell carcinoma of the anal canal. One hundred consecutive patients with histologically confirmed squamous cell carcinoma of the anal canal were treated radically with 3-dimensional conformal or intensity-modulated radiation therapy followed by brachytherapy or external beam radiotherapy boost and with concurrent mitomycin C and 5-fluorouracil. The influence on survival of pre-treatment, mean on-treatment and end-of-treatment haemoglobin (Hb) concentrations was studied. The 5-year locoregional control, disease free survival, disease specific survival and overall survival rates for all patients were 72%, 71%, 77% and 62%, respectively. In univariate analysis, patients with pre-treatment and end-of-treatment Hb > 120 g/L survived statistically significantly better compared to patients with Hb ≤ 120 g/L. Patients with mean on-treatment Hb > 120 g/L only had statistically significant better locoregional control and overall survival than patients with Hb ≤ 120 g/L. In multivariate analysis, independent prognostic factors were pre-treatment Hb (> 120 g/L vs. ≤ 120 g/L) for overall survival (hazard ratio [HR] = 0.419, 95% confidence interval [CI] = 0.190-0.927, p = 0.032) and stage (I & II vs. III) for disease specific (HR = 3.523, 95% CI = 1.375-9.026, p = 0.009) and overall survival (HR = 2.230, 95% CI = 1.167-4.264, p = 0.015). The pre-treatment, mean on-treatment and end-of-treatment Hb concentration > 120 g/L carried better prognosis for patients for with squamous cell carcinoma of the anal canal treated with radiochemotherapy. The pre-treatment Hb > 120 g/L was an independent prognostic factor for overall survival of patients with anal canal cancer.

Full Text Available Abstract Background The objective of this retrospective study is to investigate laryngeal preservation and long-term treatment results in hypopharyngeal carcinoma treated with intensity-modulated radiotherapy (IMRT combined with chemotherapy. Methods Twenty-seven patients with hypopharyngeal carcinoma (stage II-IV were enrolled and underwent concurrent chemoradiotherapy. The chemotherapy regimens were monthly cisplatin and 5-fluorouracil for six patients and weekly cisplatin for 19 patients. All patients were treated with IMRT with simultaneous integrated boost technique. Acute and late toxicities were recorded based on CTCAE 3.0 (Common Terminology Criteria for Adverse Events. Results The median follow-up time for survivors was 53.0 months (range 36-82 months. The initial complete response rate was 85.2%, with a laryngeal preservation rate of 63.0%. The 5-year functional laryngeal, local-regional control, disease-free and overall survival rates were 59.7%, 63.3%, 51.0% and 34.8%, respectively. The most common greater than or equal to grade 3 acute and late effects were dysphagia (63.0%, 17 of 27 patients and laryngeal stricture (18.5%, 5 of 27 patients, respectively. Patients belonging to the high risk group showed significantly higher risk of tracheostomy compared to the low risk group (p = 0.014. Conclusions After long-term follow-up, our results confirmed that patients with hypopharyngeal carcinoma treated with IMRT concurrent with platinum-based chemotherapy attain high functional laryngeal and local-regional control survival rates. However, the late effect of laryngeal stricture remains a problem, particularly for high risk group patients.

Objective: to correlate the results of 18 F-fluoro-2-deoxy-D-glucose ( 18 F-FDG) positron emission tomography/computed tomography (PET/CT) performed with a specific protocol for assessment of breasts with histological/immunohistochemical findings in breast carcinoma patients. Materials and methods: cross-sectional study with prospective data collection, where patients with biopsy-confirmed breast carcinomas were studied. The patients underwent PET/CT examination in prone position, with a specific protocol for assessment of breasts. PET/CT findings were compared with histological and immunohistochemical data. Results: the authors identified 59 malignant breast lesions in 50 patients. The maximum diameter of the lesions ranged from 6 to 80 mm (mean: 32.2 mm). Invasive ductal carcinoma was the most common histological type (n = 47; 79.7%). At PET/CT, 53 (89.8%) of the lesions demonstrated anomalous concentrations of 18 F-FDG, with maximum SUV ranging from 0.8 to 23.1 (mean: 5.5). A statistically significant association was observed between higher values of maximum SUV and histological type, histological grade, molecular subtype, tumor diameter, mitotic index and Ki-67 expression. Conclusion: PET/CT performed with specific protocol for assessment of breasts has demonstrated good sensitivity and was associated with relevant histological/immunohistochemical factors related to aggressiveness and prognosis of breast carcinomas.

Discriminant analysis was carried out for 48 tongue cancer patients who were treated with radium single-plane implantation. The 48 patients were grouped into 32 successfully cured without complications, five successfully cured with complications, six successfully cured but requiring additional boost therapy and five with local recurrence. To evaluate the relation between the dose distribution and the local treatment results, the analysis was based on a volume-dose relationship. The functions introduced by this discriminant analysis were linear, and the parameters used were modal dose, average dose and shape factors of histograms. Each group of treatment results had a correction rate of >80%, except for the successfully cured group with ulcers. The discriminant functions were useful as an index to obtain a final clinical treatment result at the early time of implantation, and these functions could be used as a criterion for the optimal treatment of tongue carcinoma. We were also able to recognize the limitation of the actual arrangement of sources in the single-plane implant. (author)

1987-01-01

Thirty-one patients have been treated for carcinoma of the prostate with /sup 198/Au seeds placed transperineally using transrectal ultrasonic guidance. Twenty patients have been followed postoperatively for periods ranging from 3 to 31 months, with an average follow-up time of 12 months. Cumulative dose of radiation to the prostate calculated by dosimetry was either 9000 rads or 15,000 rads. Serial transrectal ultrasound examinations performed on these patients showed a decrease in prostate size in all patients within 6 months of treatment, with a statistically significant decrease observed between the third and sixth months. No significant difference in amount or rate of tumor regression was noted when tumor stage and grade were correlated to volume decrease after treatment. Patients who received the larger doses of radiation (15,000 rads) showed a significantly greater rate of decline in prostatic volume than those who received 9000 rads. Seven patients underwent prostate biopsy between 12 and 18 months after treatment; six biopsies showed residual tumor. Complications after treatment included urinary retention because of prostatic edema (three), radiation urethritis (three), and rectal ulceration (one). Transperineal placement of /sup 198/Au is well tolerated and offers an alternative to external beam radiation for treatment of carcinoma of the prostate.

Full Text Available Lymphoepithelioma-like carcinoma (LELC of the urinary bladder is a rare variant, which can occur in a pure form or in conjunction with transitional cell carcinoma. Owing to the scarcity of reported cases, the optimum treatment is yet to be defined, although the benefits of chemotherapy are increasingly recognised. We present a case of a 64-year-old man with pure LELC, treated with trans-urethral resection of the bladder tumor (TURBT and primary gemcitabine and platinum-based chemotherapy. He remained free of disease at six-month follow-up cystoscopy. The case adds to the growing evidence for the efficacy of chemotherapy, coupled with TUR, as part of a bladder-preserving treatment option for LELC.

Objective: To investigate the side effects and curative effect in high-dosed lipiodol-transcatheter arterial chemoembolization as a treatment of large hepatocellular carcinoma. Methods: 79 patients with unresectable hepatocellular carcinoma were treated by TACE, and divided into 2 groups. In group A, 39 patients with the tumor sized 7-18cm in diameter, routine-dosed, 10-20ml lipiodol was given in TACE. 40 patients were enrolled in the high-dosed group B, who were given more than 20ml iodized oil in TACE. Results: The First to third year survival rate of group A was 66.7%, 33.3%, 0% respectively,while in group B it was 75%, 45%, 7.5% respectively. The effective rate was 71.7% in Group A and 87.5% in Group B. There was a significant difference between both groups. There was no significant difference of critical side effects and liver function damage between group A and B. Conclusion: High-dosed lipiodol chemoembolization as a treatment of unresectable hepatocellular carcinoma is superior to the routine TACE, especially when the tumor is large and the liver function reserve is good.

2006-01-01

To present a critical review of yttrium-90 (TheraSphere) for the treatment of hepatocellular carcinoma (HCC). Medical literature databases (Medline, Cochrane Library, and CANCERLIT) were searched for available literature concerning the treatment of HCC with TheraSphere. These publications were reviewed for scientific and clinical validity. Studies pertaining to the use of yttrium-90 for HCC date back to the 1960s. The results from the early animal safety studies established a radiation exposure range of 50-100 Gy to be used in human studies. Phase I dose escalation studies followed, which were instrumental in delineating radiation dosimetry and safety parameters in humans. These early studies emphasized the importance of differential arteriolar density between hypervascular HCC and surrounding liver parenchyma. Current trends in research have focused on advancing techniques to safely implement this technology as an alternative to traditional methods of treating unresectable HCC, such as external beam radiotherapy, conformal beam radiotherapy, ethanol ablation, trans-arterial chemoembolization, and radiofrequency ablation. Yttrium-90 (TheraSphere) is an outpatient treatment option for HCC. Current and future research should focus on implementing multicenter phase II and III trials comparing TheraSphere with other therapies for HCC

2016-05-23

Fibrolamellar hepatocellular carcinoma (FL-HCC) is a malignant liver tumor which is thought to be a variant of conventional hepatocellular carcinoma (HCC). It accounts for a small proportion of HCC cases and occurs in a distinctly different group of patients which are young and usually not in the setting of chronic liver disease. The diagnosis of FL-HCC requires the integration of clinical information, imaging studies, and histology. In terms of the treatment options, the only potentially curative treatment option for patients who have resectable disease is surgery either liver resection (LR) or liver transplantation (LT). When performed in a context of aggressive therapy, long-term outcomes after surgery, particularly liver resection for FL-HCC, were favorable. The clinical outcome of patients with unresectable disease is suboptimal with median survival of less than 12 months. The aim of this review is to update the available evidence on diagnosis, treatment options, outcome predictors, and recent developments of patients with this rare disease and to provide a summarized overview of the available literature.

Leucopenia or neutropenia during chemotherapy predicts better survival in several cancers. We aimed to assess whether leucopenia could be a biological measure of treatment and a marker of efficacy in advanced nasopharyngeal carcinoma (ANPC). We retrospectively analyzed 3826 patients with ANPC who received chemoradiotherapy. Leucopenia was categorised on the basis of worst grade during treatment according to the National Cancer Institute Common Toxicity Criteria version 4.0: no leucopenia (grade 0), mild leucopenia (grade 1–2), and severe leucopenia (grade 3–4). Associations between leucopenia and survival were estimated by Cox proportional hazards model. Of the 3826 patients, 2511 (65.6 %) developed mild leucopenia (grade 1–2) and 807 (21.1 %) developed severe leucopenia (grade 3–4) during treatment; 508 (13.3 %) did not. A multivariate Cox model that included leucopenia determined that the hazard ratios (HR) of death for patients with mild and severe leucopenia were 0.69 [95 % confidence interval (95 %CI) 0.56-0.85, p < 0.001] and 0.75 (95 %CI 0.59-0.95, p = 0.019), respectively; the HR of distant metastasis for patients with mild and severe leucopenia were 0.77 (95 %CI 0.61-0.96, p = 0.023) and 0.99 (95 %CI 0.77-1.29, p = 0.995), respectively. Leucopenia had no effect on locoregional relapse. Our results indicate that mild leucopenia during chemoradiotherapy is associated with improved overall survival and distant metastasis–free survival in ANPC. Mild leucopenia may indicate appropriate dosage of chemotherapy. We can identify the patients who may benefit from chemotherapy if they experienced leucopenia during the treatment. Prospective trials are required to assess whether dosing adjustments based on leucopenia may improve chemotherapy efficacy

Thyroid carcinoma in children

International Nuclear Information System (INIS)

Akhzari, F.

2002-01-01

Thyroid cancer is rare in children, with only 3-6% of thyroid malignancies occurring in children, and constitutes but 6% of head and neck tumors. Over 95% thyroid cancer are differentiated, and 10% of these occur in children of adolescents. Any of the histologic types that occur in adults may be in children, but they are most often differentiated thyroid carcinomas. The etiologies of thyroid carcinoma are unknown, but factors considered in pathogenesis include irradiation, sex and age. The incandesce of thyroid carcinoma in a solitary coddle in a child has been described as high as 70%. History and /or physical examination alone are unlikely to advance the diagnosis, and with exception of plasma CT in medullary thyroid carcinoma, blood studies are unhelpful in the diagnosis of thyroid carcinoma. Radiographs and ultrasound imaging are helpful in planning treatment and follow-up, but are unlikely to be needed for initial diagnosis. One of the main indication of thyroid scan in the pediatric group is thyroid nodule. FNAB is established as the most effective method of diagnosis in adults, although in children it may be less reliable. While radionuclide scintigraphy may be considered for initial screening, FNAB is well established and its specificity allows it to negate the need for a substantial number of operation. Treatment of differentiated thyroid carcinoma in children is more controversial. Some authors maintain that modified or subtotal thyroidectomy is appropriation this disease, others maintain that total thyroidectomy is required Nevertheless, radioiodine therapy is considered to be standard in the treatment of iodine-avid thyroid carcinomas for ablation of the thyroid remnant following surgery and for treatment of iodine-avid distant diseases. The front-line treatment of medullary thyroid carcinoma is aggressive surgery. Total thyroidectomy is indicated, In general treatment with chemotherapy, extemal radiation and I-131 are not helpful, however radioactive

Endoplasmic reticulum stress-induced resistance to doxorubicin is reversed by paeonol treatment in human hepatocellular carcinoma cells.

Directory of Open Access Journals (Sweden)

Lulu Fan

Full Text Available BACKGROUND: Endoplasmic reticulum stress (ER stress is generally activated in solid tumors and results in tumor cell anti-apoptosis and drug resistance. Paeonol (Pae, 2-hydroxy-4-methoxyacetophenone, is a natural product extracted from the root of Paeonia Suffruticosa Andrew. Although Pae displays anti-neoplastic activity and increases the efficacy of chemotherapeutic drugs in various cell lines and in animal models, studies related to the effect of Pae on ER stress-induced resistance to chemotherapeutic agents in hepatocellular carcinoma (HCC are poorly understood. METHODOLOGY/PRINCIPAL FINDINGS: In this study, we investigated the effect of the endoplasmic reticulum (ER stress response during resistance of human hepatocellular carcinoma cells to doxorubicin. Treatment with the ER stress-inducer tunicamycin (TM before the addition of doxorubicin reduced the rate of apoptosis induced by doxorubicin. Interestingly, co-pretreatment with tunicamycin and Pae significantly increased apoptosis induced by doxorubicin. Furthermore, induction of ER stress resulted in increasing expression of COX-2 concomitant with inactivation of Akt and up-regulation of the pro-apoptotic transcription factor CHOP (GADD153 in HepG2 cells. These cellular changes in gene expression and Akt activation may be an important resistance mechanism against doxorubicin in hepatocellular carcinoma cells undergoing ER stress. However, co-pretreatment with tunicamycin and Pae decreased the expression of COX-2 and levels of activation of Akt as well as increasing the levels of CHOP in HCC cells. CONCLUSIONS/SIGNIFICANCE: Our results demonstrate that Pae reverses ER stress-induced resistance to doxorubicin in human hepatocellular carcinoma cells by targeting COX-2 mediated inactivation of PI3K/AKT/CHOP.

(1) Microspheres containing radioactive yttrium-90 (90Y) are infused into the hepatic artery. These deliver high doses of ionizing radiation to inoperable hepatocellular carcinoma, the most common type of primary liver cancer. (2) Limited evidence from several case series indicates that palliative therapy with 90Y microspheres may reduce tumour size and increase survival time. (3) In some patients, 90Y treatment may result in enough tumour reduction to permit liver resection or transplantation. (4) While 90Y microsphere therapy is generally well tolerated, major complications and several treatment-related deaths have occurred. Improved patient selection criteria and technical changes to microsphere delivery have reduced the risks of complications and death. (5) Patient selection and the technical aspects of 90Y microsphere treatment are complex and require the coordinated expertise of a multidisciplinary team.

Thymic carcinoma is a rare cancer with a poor prognosis. A definitive management approach has yet to be confirmed by a high level of evidence.Case presentation: We present the case of a 41-year-old female who underwent curative-intent surgery for a stage III squamous cell carcinoma of the thymus. Bone metastases were detected 1 year later by magnetic resonance imaging. These were treated with palliative-intent radiotherapy. Disease progression has not been observed in more than 15 years since the achievement of complete radiological remission.Conclusion: The treatment outcomes in this and other reported cases suggest that some patients with oligometastatic thymic carcinoma may achieve prolonged survival or even cure with low-dose radiotherapy delivered to the metastases.

In order to claim a benefit of screen-based diagnosis for asymptomatic individuals, treatment of occult disease needs to offer survival advantages compared to the treatment of symptomatic disease, yet information on this issue is scarce with regard to hepatocellular carcinoma (HCC) screening. A total of 3353 treatment-naïve, consecutive, newly diagnosed HCC patients [age: 57.9 ± 10.3, male: 2,689 (80.2%), hepatitis B virus: 2555 (76.2%)], diagnosed between 2010 and 2013 were analyzed. Data on the mode of detection was prospectively collected at the time of HCC diagnosis and was used to group patients into occult or symptomatic cases. Overall, 643 (19.2%) patients were symptomatic cases. The proportion of patients undergoing resection, radiofrequency ablation or transplantation were lower in symptomatic cases than occult cases (20.8 vs. 56.2%, p offered a survival benefit to patients over symptomatic cases. These data support screening practices for asymptomatic individuals to diagnose occult HCC.

, complications, histopathological analysis and invasion of the contralateral lobe were analyzed. Patients' ages varied from 17 to 89; the most frequent histopathological pattern was the classical papillary carcinoma (18 cases, followed by follicular carcinoma (6; the follicular variant of the papillary carcinoma (2 and the Hürthle cell carcinoma (1. Twenty-one patients underwent full thyroidectomies, from 15 to 30 days after the first intervention. RESULTS: the contralateral lobe analysis was negative for carcinoma in 16 (76.5% and positive in the other 5 (23.8% patients. The complications observed were temporary dysphonia (3 cases and hypoparathyroidism (2 cases, one permanent. CONCLUSIONS: total thyroidectomy is important in the treatment of differentiated thyroid carcinomas, because there is a high contralateral spread rate (23.8%. It is a procedure without mortality, which bears few complications.

Full Text Available ObjectiveTo compare clinical efficacy and recurrence between surgical resection and radiofrequency ablation (RFA in the treatment of small hepatocellular carcinoma (HCC. MethodsThe clinical data of 97 patients with small HCC, who underwent surgical resection or RFA as the initial treatment in The First Hospital of Jilin University from January 2002 to December 2008, were collected. Sixty-three cases, who survived 2 years after treatment, were followed up; of the 63 cases, 34 underwent surgical resection, and 29 underwent RFA. The recurrence of these patients was analyzed retrospectively. The measurement data were analyzed by chi-square test. The Cox regression analysis was used for determining the risk factors for recurrence. The log-rank test was used for disease-free survival (DFS difference analysis. ResultsThe 3-month, 1-year, and 2-year intrahepatic recurrence rates for the patients who underwent surgical resection were 15%, 38%, and 64%, respectively, versus 21%, 35%, and 45% for those who underwent RFA, without significant differences between the two groups of patients. The intrahepatic recurrence after initial treatment was not significantly associated with treatment method, sex, age, Child-Pugh grade, tumor size, number of nodules, presence of cirrhosis, and alpha-fetoprotein level. There was no significant difference in DFS between the two groups of patients. ConclusionRFA produces a comparable outcome to that by surgical resection in the treatment of small HCC. RFA holds promise as a substitute for surgical resection.

Full text: Hyperthermia treatment planning (HTP) is a useful tool for improvement of clinical hyperthermia treatments. Aim of this study was to determine the correlation between HTP and measurements during hyperthermia treatments. We compared the calculated specific absorption rate (SAR) with clinically measured SAR-values, from ΔT-measurements, in cervix carcinoma patients. General difficulties for such clinical verifications are changes in the anatomy during the different steps and possible movement of the catheters. We used one fixed invasive catheter in the tumor additional to the usual non-invasive catheters in the vagina, bladder and rectum, for insertion of multisensor thermocouple probes. A special CT-scan with the patient in treatment position and the catheters in situ was made for the HTP. We performed these verifications in a total of 11 treatments in 7 patients. The main difficulties for accurate verification were of clinical nature: difficulties arising from the use of gynaecological tampon and the limited number of measurements in tissue. Remaining air in the vagina and sub-optimal tissue contact of the catheters resulted in bad thermal contact between thermocouples and tissue, causing measurement artefacts that are difficult to correlate with calculations. These artefacts are probably not specific for thermocouple measurements, but more general for intraluminal temperature and SAR measurements. (author)

The purpose of this study is to present the treatment results and to identify possible prognostic indicators in patients with locally advanced hypopharyngeal carcinoma. Materials and Methods: Between October 1985 to December 2000, 90 patients who had locally advanced stage IV hypopharyngeal carcinoma were studied retrospectively. Twelve patients were treated with radiotherapy alone, 65 patients were treated with a combination of chemotherapy and radiotherapy, and 13 patients were treated with surgery and postoperative radiotherapy with or without neoadjuvant chemotherapy. Total radiation dose ranged from 59.0 to 88.2 Gy (median 70 Gy) for radiotherapy alone. Most patients had ciplatin and 5-fluorouracil, and others had cisplatin and peplomycin or vincristin. Median follow-up period was 15 months. Kaplan-Meier method was used for survival rate and Cox proportional hazard model for multivariate analysis of prognostic factors. Results: Overall 3- and 5-year survival rates were 27% and 17%, respectively. The 2-year locoregional control rates were 33% for radiotherapy alone, 32% for combined chemotherapy and radiotherapy, and 81% for combined surgery and radiotherapy (p=0.006). The prognostic factors affecting overall survival were T stage, concurrent chemo radiation and treatment response. Overall 3- and 5-year laryngeal preservation rates in combined chemotherapy and radiotherapy were 26% and 22%, respectively. Of these, the 5-year laryngeal preservation rates were 52% for concurrent chemo radiation group (n=11), and 16% for neoadjuvant chemotherapy and radiotherapy (n=54, p=0.012). Conclusion: Surgery and postoperative radiotherapy showed better results than radiotherapy alone or with chemotherapy. Radiotherapy combined with concurrent chemotherapy is an effective modality to achieve organ preservation in locally advanced hypopharyngeal cancer. Further prospective randomized studies will be required

Million, R.R.; Bova, F.J.

1987-01-01

Although squamous cell carcinoma of the head and neck represents only 5% of all malignancies, the head and neck area is one of the few anatomical areas remaining where radiotherapy is often used as the only modality for cure and often with substantial doses. There are at least 35 separate anatomical sites for origin of squamous cell carcinoma in the upper respiratory tract, and each site has its own distinctive pattern of spread, incidence of regional and distant metastases, and varying stages of presentation. It would be impossible in this short chapter to cover every contingency for treatment planning, and only general principles are outlined

The value of radiotherapie in the treatment of the carcinoma of the vulva

International Nuclear Information System (INIS)

Lochmueller, H.

1983-01-01

In carcinoma of the vulva radical vulvectomy and lymphadenectomy are the treatments of choice if general, condition of the patient size and site of tumor are apt for surgery. The alternative method in high risk patients is a combination of surgical and radiotherapeutic treatment like electrocoagulation, resection, and radiation of the lymph vessels or electroresection and local electron-radiation at the surgically exposed area as well as inguinal and iliacal telecobalt treatment of the lymphnodes sometimes combined with selective lymphadenectomy. Radiation therapy itself as primary treatment seems to be inferior to other methods. The interstitial radiation treatment is only indicated in recurrencies or small tumors which are located in regions which are difficult to reach by surgery. (orig.)

Materials and Methods Cross-sectional study with prospective data collection, where patients with biopsy-confirmed breast carcinomas were studied. The patients underwent PET/CT examination in prone position, with a specific protocol for assessment of breasts. PET/CT findings were compared with histological and immunohistochemical data. Results The authors identified 59 malignant breast lesions in 50 patients. The maximum diameter of the lesions ranged from 6 to 80 mm (mean: 32.2 mm. Invasive ductal carcinoma was the most common histological type (n = 47; 79.7%. At PET/CT, 53 (89.8% of the lesions demonstrated anomalous concentrations of 18F-FDG, with maximum SUV ranging from 0.8 to 23.1 (mean: 5.5. A statistically significant association was observed between higher values of maximum SUV and histological type, histological grade, molecular subtype, tumor diameter, mitotic index and Ki-67 expression. Conclusion PET/CT performed with specific protocol for assessment of breasts has demonstrated good sensitivity and was associated with relevant histological/immunohistochemical factors related to aggressiveness and prognosis of breast carcinomas.

Head and neck: treatment of primary and relapsed nasopharyngeal carcinoma

International Nuclear Information System (INIS)

Wang, C.C.

1995-01-01

Purpose/Objective: Nasopharyngeal carcinoma (NPC) is not a common malignancy of the head and neck in the United States and presents a great challenge to the radiation oncologists in this country. Its management is radiotherapeutic and technically demanding and calls for careful treatment techniques to include the primary and the lymphatic drainage areas to high doses while sparing the neighboring organs such as the spinal cord, eyes, temporal lobes and midrain. This refresher course will review the clinical course, pattern of spread with manifestations of various neurologic syndromes of the disease. The radiotherapeutic management of primary lesion will be discussed in detail including the treatment techniques, placement of the irradiation portals, dose levels, etc. Treatment results as reported in the literature as well as those achieved at the MGH will be presented. Special emphasis will be placed on the routine use of intracavitary implant to boost the primary site and its technical aspects. Relapsed NPC after previous radiation therapy presents a difficult problem in management, but can be re-irradiated with occasional success by observing careful technique and fractionated intracavitary brachytherapy and the local control rates will be briefly covered. Recurrent disease in the neck will be managed by neck dissection. Xerostomia is undesirable and common sequelae following radical radiation therapy for NPC. Efforts are being made to decrease its magnitude by using higher energies of photons, i.e. 10 MV to spare a portion of the parotid glands with some promising results. Because of the unique location of the primary lesion, currently a modified BID program (MBID) is used and its techniques and treatment concept are discussed

To investigate the efficacy and safety of transarterial chemoembolization (TACE)-based multimodal treatment in patients with large hepatocellular carcinoma (HCC). A total of 146 consecutive patients were included in the analysis, and their medical records and radiological data were reviewed retrospectively. In total, 119 patients received TACE-based multi-modal treatments, and the remaining 27 received conservative management. Overall survival (P<0.001) and objective tumor response (P=0.003) were significantly better in the treatment group than in the conservative group. After subgroup analysis, survival benefits were observed not only in the multi-modal treatment group compared with the TACE-only group (P=0.002) but also in the surgical treatment group compared with the loco-regional treatment-only group (P<0.001). Multivariate analysis identified tumor stage (P<0.001) and tumor type (P=0.009) as two independent pre-treatment factors for survival. After adjusting for significant pre-treatment prognostic factors, objective response (P<0.001), surgical treatment (P=0.009), and multi-modal treatment (P=0.002) were identified as independent post-treatment prognostic factors. TACE-based multi-modal treatments were safe and more beneficial than conservative management. Salvage surgery after successful downstaging resulted in long-term survival in patients with large, unresectable HCC.

The efficacy of radiation therapy for feline advanced cutaneous squamous cell carcinoma was evaluated. A full course radiation therapy protocol was applied to six cats showing single or multiple facial squamous cell carcinomas, in a total of seven histologically confirmed neoplastic lesions. Of the lesions, one was staged as T{sub 1}, and six as T{sub 4} according to WHO staging system of epidermal tumors. The animals were submitted to twelve radiation fractions of 4 Gy each, on a Monday-Wednesday-Friday schedule, and the equipment used was an orthovoltage unit. Energy used was 120 kV, 15 mA and 2 mm aluminum filter. The cats were evaluated during the treatment and 30 and 60 days after the end of the radiation therapy. In this study, 87% of the lesions had complete remission and 13% partial remission to the treatment. Side effects were considered mild according to Veterinary Radiation Therapy Oncology Group Toxicity criteria, and included erythema, epilation and rhinitis. Radiation Therapy was considered safe for feline cutaneous squamous cell carcinoma, leading to mild side effects and can represent a good therapeutic option. (author)

Full Text Available Abstract Background In head and neck cancer, bilateral neck irradiation is the standard approach for many tumor locations and stages. Increasing knowledge on the pattern of nodal invasion leads to more precise targeting and normal tissue sparing. The aim of the present study was to evaluate the morbidity and tumor control for patients with well lateralized squamous cell carcinomas of the oral cavity and oropharynx treated with ipsilateral radiotherapy. Methods Twenty consecutive patients with lateralized carcinomas of the oral cavity and oropharynx were treated with a prospective management approach using ipsilateral irradiation between 2000 and 2007. This included 8 radical oropharyngeal and 12 postoperative oral cavity carcinomas, with Stage T1-T2, N0-N2b disease. The actuarial freedom from contralateral nodal recurrence was determined. Late xerostomia was evaluated using the European Organization for Research and Treatment of Cancer QLQ-H&N35 questionnaire and the National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE, version 3. Results At a median follow-up of 58 months, five-year overall survival and loco-regional control rates were 82.5% and 100%, respectively. No local or contralateral nodal recurrences were observed. Mean dose to the contralateral parotid gland was 4.72 Gy and to the contralateral submandibular gland was 15.30 Gy. Mean score for dry mouth was 28.1 on the 0-100 QLQ-H&N35 scale. According to CTCAE v3 scale, 87.5% of patients had grade 0-1 and 12.5% grade 2 subjective xerostomia. The unstimulated salivary flow was > 0.2 ml/min in 81.2% of patients and 0.1-0.2 ml/min in 19%. None of the patients showed grade 3 xerostomia. Conclusion In selected patients with early and moderate stages, well lateralized oral and oropharyngeal carcinomas, ipsilateral irradiation treatment of the primary site and ipsilateral neck spares salivary gland function without compromising loco-regional control.

A variety of unfulfilled needs may trigger doctor-shopping behavior (DSB) in patients. In oncology, treatment results usually cause patients the most concern. This study investigated the association of DSB with active treatments received by patients with hepatocellular carcinoma (HCC) and outcomes. With approval from the institutional review board, all patients registered in the cancer database of a teaching hospital and diagnosed as having HCC by self-referral from outside hospitals or by in-house diagnosis were retrospectively identified. Patient data were then reviewed and analyzed via electronic medical records. Hepatitis B carriers were significantly more likely than noncarriers to show first-time DSB. Recurrent disease was less likely to result in DSB than predicted. Patients from outside hospitals not receiving upfront first treatment after diagnosis were significantly more likely to show more frequent DSB than those receiving it. Male patients eligible for salvage treatment were less likely to have frequent occurrences of DSB than their female counterparts. Receiving first salvage treatment was not associated with more frequent DSB. Treatment recommendations offered in the study hospital did not influence patients' decisions to leave or stay. Only elderly patients (>70 years) were less likely to show DSB. DSB can occur throughout the entire course of treatment for HCC for a variety of reasons. Active treatments, disease status, and patient characteristics all exerted an influence on DSB.

Osteoradionecrosis is most commonly caused by radiation-induced injury. We report on 3 cases of temporal bone necrosis that occurred after chemoradiotherapy for nasopharyngeal carcinoma performed more than 10 years previously. Case 1 was a 42-year-old woman who had nasopharyngeal carcinoma in 1991. The patient underwent chemoradiotherapy (70 Gy total) in 1991, and gamma knife irradiation (20 Gy) in 1998 for local recurrence. The bone in the posterior wall of the left external auditory canal began to be exposed in 2003. Otorrhea from the left ear increased and we found a skin defect and ulcer formation in the postauricular region. We performed radical mastoidectomy and debridement on April, 2010. The area of the defect was covered and filled in with a pedicle musculoperiosteal flap. The intra-aural skin became dry in 6 months, however, she lost consciousness due to a temporal lobe abscess and underwent an emergency operation on April, 2011. After operation, the patient recovered with no neurological symptoms and infections up to the present date. Case 2 was a 58-year-old man who had nasopharyngeal carcinoma in 2001. The patient underwent chemoradiotherapy (66 Gy total) in 2001, and X knife irradiation (15 Gy) 3 months later due to the remaining tumor. The left posterior ear canal wall collapsed and the tympanic membrane retracted with pooling epithelial debris appearing in 2007. Left facial nerve palsy was seen in December 2010. We performed a mastoidectomy on January, 2011. Cholesteatoma and necrotic granuloma with fragile bone filled the mastoid cavity, and a facial canal bone defect was seen. Bone necrosis with cholesteatoma and inflammatory granuloma was revealed by the pathological examination. The facial palsy improved after the operation. Case 3 was a 59-year-old man who had left abducens palsy with nasopharyngeal carcinoma invading the clivus. The patient underwent chemoradiotherapy (60 Gy total) in 2001, and X knife irradiation (24 Gy) 4 months later for

Radiotherapy is used to treat a wide variety of head and neck tumours that arise in and around the skull base. The delayed effects of radiation damages a range of structures, including the nervous system, bone, major vessels, mucus membranes, pituitary and salivary glands, as well as increasing the risk of radiation-induced neoplasms. In this review the complications resulting from radiation treatment for nasopharyngeal carcinoma (NPC), a cancer treated with a high dose of radiation to a fairly large region, are illustrated. Many patients with NPC have a long-term survival, so are at risk of developing delayed radiation effects, and hence may demonstrate a wide range of complications on imaging. Other tumours around the skull base treated with radiotherapy include meningiomas, chordomas, chondrosarcomas, pituitary adenomas, paranasal sinus and nasal cavity tumours. In these cases similar complications may be encountered on imaging, although the severity, incidence and location will vary

Objective: To explore the diagnostic and therapeutic efficacy of interventional procedure for upper gastrointestinal bleeding in patients of hepatic carcinoma accompanied with hepatic artery-portal vein shunting (HAPVS). Methods: Clinical data of 27 patients of hepatic carcinoma accompanied with HAPVS were retrospectively analyzed. All patients underwent hepatic arterial angiography and transcatheter arterial embolization. Shunts were embolized with coils, Gelfoam particles or PVA particles. Results: Of 27 patients with upper gastrointestinal bleeding, central type HAPVS was seen in 16 and peripheral type HAPVS in 11. Reversed portal venous flow was detected in 20 cases and ascites was found in 23 cases. The abnormal shunts were successfully occluded in all patients and the bleeding ceased within 2 days after embolization. No recurrent bleeding occurred in one month after the treatment. Ascites disappeared in 16 cases and subsided in 7 cases. Conclusion: HAPVS is an important cause for upper gastrointestinal bleeding in patients of hepatic carcinoma, and the arteriovenous fistula can be confirmed with hepatic artery DSA. Embolization of fistulous orifice is the most effective therapy for such patients. (authors)

2004-01-01

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

The purpose of this study was to determine the prognostic factors affecting local outcomes for patients with T2N0 glottic carcinoma treated by definitive radiotherapy. A total of 48 patients with T2N0 squamous cell carcinoma treated by definitive radiotherapy between 1992 and 2005 were studied. Cumulative probability of overall survival, cause-specific survival, local control and larynx-preserving were calculated according the Kaplan-Meier method, and the prognostic significance of patient's age, number of subsites involved, impaired cord mobility, anterior commisure involved, total dose and overall treatment time were analyzed using the log-rank test in univariate analysis and Cox regression in multivariate analysis. Follow-up ranged from 13 to 141 months (median, 62 months). Five-year survivals were: overall, 95.3%; cause-specific, 97.9% and five years rates were local control, 61.4%; larynx-preserving, 76.4%. Multivariate analyses of the six parameters showed that overall treatment time significantly influenced the probability of local control, and impaired mobility and overall treatment time affected the probability of larynx-preserving. Our study showed that longer overall treatment time significantly worsened the percentage of local control and larynx-preserving for patients with T2N0 glottic carcinoma treated with definitive radiotherapy. Therefore, we suggest treating, the patients in a shorter treatment course. (author)

Background: Our previous results for treatment of hepatocellular carcinoma (HCC) with proton beam therapy revealed excellent local control with low toxicity. Three protocols were used to avoid late complications such as gastrointestinal ulceration and bile duct stenosis. In this study, we examined the efficacy of these protocols. Methods and Materials: The subjects were 266 patients (273 HCCs) treated by proton beam therapy at University of Tsukuba between January 2001 and December 2007. Three treatment protocols (A, 66 GyE in 10 fractions; B, 72.6 GyE in 22 fractions; and C, 77 GyE in 35 fractions) were used, depending on the tumor location. Results: Of the 266 patients, 104, 95, and 60 patients were treated with protocols A, B, and C, respectively. Seven patients with double lesions underwent two different protocols. The overall survival rates after 1, 3 and 5 years were 87%, 61%, and 48%, respectively (median survival, 4.2 years). Multivariate analysis showed that better liver function, small clinical target volume, and no prior treatment (outside the irradiated field) were associated with good survival. The local control rates after 1, 3, and 5 years were 98%, 87%, and 81%, respectively. Multivariate analysis did not identify any factors associated with good local control. Conclusions: This study showed that proton beam therapy achieved good local control for HCC using each of three treatment protocols. This suggests that selection of treatment schedules based on tumor location may be used to reduce the risk of late toxicity and maintain good treatment efficacy.

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

Full Text Available Background. Carcinoma vulva is a rare disease accounting for 1.3% of all gynaecological malignancies. The present study is a 10-year retrospective review of our experience of the surgical options, morbidity, failure pattern, and survival for invasive carcinoma vulva. Materials and Methods. Retrospective analysis of case records of 39 patients who underwent surgery for invasive vulval cancer between 2004 and 2013 in the Department of Surgical Oncology at the Government Royapettah Hospital, Chennai. Results. The median age was 55 years. Radical vulvectomy was the preferred surgery. 31 patients underwent lymphadenectomy. Seroma formation and groin skin necrosis were the most common postoperative complications. With a median follow-up of 32 months, 8 patients (20.5% developed recurrence (systemic = 1, regional = 4, and local = 3. The estimated 5-year disease-free survival (DFS was 65.4% and the overall survival (OS was 85.1%. On univariate analysis, stage and lymph node involvement significantly affected OS. Nodal involvement with extracapsular spread (ECS significantly affected both DFS and OS. Conclusion. The treatment of carcinoma vulva should be individualized with multidisciplinary cooperation. The paucity of data, especially from India, necessitates the need for more studies, preferably multicentric, keeping in mind the low prevalence.

Purpose: The optimal management of breast cancer in elderly women is not well established. Therefore, the present study was undertaken to evaluate the outcome of breast cancer in elderly women treated with breast-conserving surgery and definitive breast irradiation. Methods and Materials: An analysis was performed of 558 women age ≥ 50 years treated with breast-conserving surgery and definitive breast irradiation for Stages I-II invasive carcinoma of the breast. Of the 558 total women, there were 173 elderly women age ≥ 65 years and a comparison group of 385 women age 50-64 years. Treatment for all women included complete gross excision of the primary tumor, pathologic axillary lymph node staging, and definitive breast irradiation. Adjuvant systemic chemotherapy was used in 18% (102 out of 558) of the overall group. Adjuvant tamoxifen was used in 17% (94 out of 558) of the overall group. The median follow-up after treatment was 6.2 years (mean = 6.4 years; range 0.1-15.4 years). Results: Elderly patients age ≥ 65 years and patients age 50-64 years were both found to have tumors with adverse prognostic features, including clinical T2 lesions (43 vs. 34%, respectively; p = 0.055), estrogen receptor negativity (9 vs. 16%, respectively; p = 0.13), and progesterone receptor negativity (17 vs. 21%, respectively; p = 0.50). Pathologic axillary lymph node staging showed that 24% of the elderly women were node positive, including 8% with four or more positive nodes, which was not different from women age 50-64 years (p = 0.23). There was no difference between the two age groups for the rate of deaths from breast cancer at 10 years (13 vs. 13%, respectively; p = 0.71). However, there was a significant difference between the two age groups for the rate of deaths from intercurrent disease at 10 years (11 vs. 2%, respectively; p = 0.0006). There were no differences between the two age groups for the 10-year rates of overall survival (77 vs. 85%, respectively; p = 0

AIM: To provide an update on the aetiology, pathogenesis, diagnosis, staging and management of rectal squamous cell carcinoma (SCC). METHODS: A systematic review was conducted according to the preferred reporting items for Systematic Reviews and Meta-Analyses guidelines. A comprehensive search of Ovid MEDLINE was performed with the reference list of selected articles reviewed to ensure all relevant publications were captured. The search strategy was limited to the English language, spanning from 1946 to 2015. A qualitative analysis was undertaken examining patient demographics, clinical presentation, diagnosis, staging, treatment and outcome. The quantitaive analysis was limited to data extracted on treatment and outcomes including radiological, clinical and pathological complete response where available. The narrative and quantitative review were synthesised in concert. RESULTS: The search identified 487 articles in total with 79 included in the qualitative review. The quantitative analysis involved 63 articles, consisting of 43 case reports and 20 case series with a total of 142 individual cases. The underlying pathogenesis of rectal SCC while unclear, continues to be defined, with increasing evidence of a metaplasia-dysplasia-carcinoma sequence and a possible role for human papilloma virus in this progression. The presentation is similar to rectal adenocarcinoma, with a diagnosis confirmed by endoscopic biopsy. Many presumed rectal SCC’s are in fact an extension of an anal SCC, and cytokeratin markers are a useful adjunct in this distinction. Staging is most accurately reflected by the tumour-node-metastasis classification for rectal adenocarcinoma. It involves examining locoregional disease by way of magnetic resonance imaging and/or endorectal ultrasound, with systemic spread excluded by way of computed tomography. Positron emission tomography is integral in the workup to exclude an external site of primary SCC with metastasis to the rectum. While the

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

We analyzed the results of radiotherapy in 36 patients with hypopharyngeal carcinoma. The overall 2-year and 5-year survival rates were 45.3% and 31.1%, respectively. For 23 patients given radical irradiation, the corresponding figures were 37.8% and 28.3%. However, in 16 patients receiving a combined therapy of radical irradiation and chemotherapy, mainly an intraarterial injection of cisplatin, the survivals were better; the 2-year survival rate was 50.0% and four patients have survived for more than three years without recurrence. In managing patients with hypopharyngeal carcinoma, this combined therapy would improve therapeutic outcome and also assist in larynx preservation. (J.P.N.)

The effect of concurrent combined treatment with 22.5 Gy of radiation and 110 mg of bleomycin or 55 mg of peplomycin on oral carcinoma involving the mandible was examined histologically. In 14 of 18 patients who had mandibles resected after this combined treatment, bone invasion by carcinoma was observed histologically. According to Shimosato's classification of histological effects, 3 belonged to Grade III/IV, 4 to IIb, 3 to IIa and 4 to I. The formation of new bone that was considered to be reparable was observed in the marked effective patients. In 4 patients the Grade IIb, residual surviving cancer cells were observed in the mandible. Accordingly, excision was needed in the area of radiologic features of mandibular infiltration. But it is considered that although the excision scope for the patient who has received the preoperative treatment is the same as that for the patient who has not, it is advantageous for the former patient that a wider safety region is obtained.

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

Full Text Available Abstract Background PMS2 expression loss was reported in a variety of human. However, its importance has not been fully understood in cervical carcinoma. The aim of this study was to determine the expression of PMS2 in cervical carcinoma and evaluate the significance of mismatch repair gene PMS2 regulated by glycogen synthase kinase 3β (GSK-3β in chemosensitivity. Methods We examined PMS2 and phosphorylated GSK-3β(s9 expression in cervical carcinoma tissues using immunohistochemical staining. Furthermore, we detected PMS2 expression in HeLa cells and evaluate the interaction with GSK-3β after transfection with GSK-3β by small interference RNA (siRNA, co-immunoprecipitation and immunoblotting. We also evaluated the effect of PMS2 transfection on HeLa cells' chemosensitivity to cisplatin treatment. Results We found significant downregulation of PMS2 in cervical carcinoma, which was negatively associated with phosphorylated GSK-3β (s9. Furthermore, we demonstrated GSK-3β transfection was able to interact with PMS2 and enhance PMS2 production in HeLa cells, and increased PMS2 production was responsible for enhanced chemosensitivity. Conclusions Our results provide the evidence that stabilization of PMS2 production by GSK-3β was important to improve chemosensitization, indicating the significance of GSK-3β-related PMS2 downregulation in the development of cervical carcinoma and in developing a potential strategy for chemotherapy.

The management of in situ lesions ductal carcinoma in situ (DCIS) and lobular carcinoma in situ (LCIS) continues to evolve. These diagnoses now comprise a large burden of mammographically diagnosed cancers, and with a global trend towards more population-based screening, the incidence of these lesions will continue to rise. Because outcomes following treatment for DCIS and LCIS are excellent, there is emerging controversy about what extent of treatment is optimal for both diseases. Here we review the current approaches to the diagnosis and treatment of both DCIS and LCIS. In addition, we will consider potential directions for future management of these lesions.

Full Text Available Context (Background: Imiquimod (IMQ 5% cream is an immunomodulatory and antitumorigenic agent, which was used as a topical treatment regimen, who had periocular basal cell carcinoma (BCC. Aim: This study aims to present three cases with large BCC at the medial canthal area treated with IMQ 5% cream. Materials and Methods: IMQ 5% cream was used in three patients with ages 45, 49, and 73 who preferred medical treatment over surgery. Following incisional biopsy IMQ cream was used once a day, 5 times a week and the patients were followed up weekly during 12 week treatment period and monthly after the clearance of the lesion. Results: Erythema and erosion on the surface of the lesion, injection of conjunctiva, burning and itching sensation, epiphora and punctate keratitis were seen in all patients during the treatment period. The ophthalmic side effects could be managed by topical lubricating eye drops and the inflammatory reactions resolved within 1 month after cessation of therapy. The patients were followed up for at least 3 years without tumor recurrence and the biopsies taken from the suspected area were found to be tumor free. Conclusion: Surgical excision of carcinoma of the eyelid at medial canthal area can be difficult without causing damage to the lacrimal system and reconstruction of the defect may need grafts or flaps. IMQ may provide an alternative therapy to surgery in certain cases.

Collision tumor of the thyroid: follicular variant of papillary carcinoma and squamous carcinoma

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

Objective: To summarize the outcome of nasopharyngeal carcinoma (NPC) treated by helical tomotherapy in the Chinese PLA general hospital. Methods: Between September 2007 and August 2010, 121 newly diagnosed NPC patients were treated by radiotherapy with Tomotherapy system, with (n =90) or without (n = 31) concurrent chemotherapy or molecular target therapy. The prescription dose was 70 - 74 Gy/33f to primary tumor and positive lymph node planning target volume, 60.0 - 62.7 Gy/33f to high risk planning target volume, and 52 -56 Gy/33f to low risk planning target volume. Acute side-effects were evaluated with RTOG/EORTC criteria. Results: The remission rate of primary lesion and positive lymph nodes was 95.0% and 99.0%, respectively. The follow-up rate was 100%. The number of patients with 1, 2 and 3 years followed-up were 99, 49, and 7. The 1-, 2-and 3-year local relapse-free survival rates were 97.30%, 97.3% and 97.3%, respectively. The 1-, 2-and 3-year nodal relapse-free survival rates were 100%, 100% and 100%, respectively. The 1-, 2-and 3-year distant metastasis-free survival rates were 98.4%, 96.3% and 96.3%, respectively. The 1-, 2-and 3-year overall survival rates were 96.5%, 92.6% and 86.8%, respectively. Acute toxicities of skin, oral mucosa and xerostomia with grade 0, 1, 2 and 3 were 5.0%, 74.4%, 15.7% and 4.9%; 0.8%, 37.2%, 57.9% and 4.1%; 3.3%, 53.7%, 43.0% and 0%, respectively. Xerostomia restored with time, no grade 2 or more xerostomia was observed 1 year after radiation therapy. Concurrent chemotherapy significantly increased incidence of mucositis, esophagitis and tracheitis. Conclusion: Helical tomotherapy is efficient, secure and effective modality for the treatment of nasopharyngeal carcinoma. (authors)

Radioactive iodine ( 131 I) was used in the treatment of a 12-year-old female dog with hyperthyroidism resulting from a large, unresectable (and metastatic) thyroid carcinoma associated with signs of severe inspiratory stridor and dyspnea. Hyperthyroidism was diagnosed on the basis of clinical signs (polyuria, polydipsia, polyphagia, weight loss, nervousness) and high basal serum thyroxine (T4) concentrations, as well as thyroid radioiodine kinetic studies that showed a high radioiodine uptake into the thyroid (% thyroid uptake) and markedly increased serum concentrations of protein-bound iodine-131 (PB 131 I) after 131 I tracer injection. Thyroid imaging revealed diffuse radionuclide accumulation by the tumor, which involved both thyroid lobes. The dog was treated with three large doses of radioiodine ( 131 I), ranging from 60 to 75 mCi, given at intervals of 5 to 7 months. The dog became euthyroid, and the size of the tumor decreased by approximately 25% after each 131 I treatment, improving the severe inspiratory stridor and dyspnea, but both the hyperthyroid state and breathing difficulty recurred within a few months of each treatment. The dog was euthanatized 5 months after the last treatment because of progressive tracheal compression and pulmonary metastasis

Sunitinib, a multitargeted tyrosine kinase inhibitor, is widely used in the treatment of carcinoma. Adverse events associated with this treatment, including fatigue, diarrhea, and hematotoxicity, have been reported in clinical trials. Bowel perforation is a surgical emergency that requires immediate treatment depending on the location and progression of the tumor. We report 2 cases of bowel perforation during sunitinib treatment. The patients presented with diffuse peritonitis, and emergency exploratory laparotomy was performed. We speculate that the underlying mechanisms were decrease in capillary density of the normal mucosa in case 1 and tumor shrinkage because of sunitinib treatment in case 2. To the best of our knowledge, this is the first study to report the pathological findings implicating bowel perforation due to sunitinib treatment. Further investigations are needed to clarify the risk factors for intestinal perforations associated with sunitinib treatment.

Fifty patients with invasive bladder carcinoma were treated with neoadjuvant intra-arterial chemotherapy using doxorubicin or pirarubicin, and this was combined with low dose radiotherapy. All of 50 patients were evaluated for clinical and histological efficacy. Twenty-nine of 50 (58%) patients achieved a clinically complete remission (CR) and 17 of 50 (34%) achieved a clinically partial remission (PR). Twenty-eight of 50 (56%) achieved a histological CR and 13 of 50 (26%) achieved a histological PR. The patients who underwent bladder preservation operations after this treatment and were followed up for longer than 3 years were evaluated for long-term results. The 5-year survival for 35 patients in this group was 74.1%. The 5-year survival for patients with a clinical CR was 93.3%, and for patients with a clinical PR it was 45.3%. The survival for patients with a histological CR was 93.3%, and for patients with a histological PR, it was 85.7%. This study suggests that neoadjuvant intra-arterial chemotherapy plus radiotherapy is a useful regimen that could become the treatment of first choice for patients with invasive bladder carcinoma. Patients who achieved a histological CR or PR with this regimen, might be able to retain the function of their bladders. (author)

At the Proton Medical Research Centre, University of Tsukuba, a pilot study of proton-beam radiotherapy was performed in 12 patients with the following types of carcinoma: Bowen's disease (4), oral verrucous carcinoma (5), and squamous cell carcinoma (3). They received total doses of 51-99.2 Gy in fractions of 2-12.5 Gy. All tumours responded well to the treatment. All four lesions of Bowen's disease, three of the five oral verrucous carcinomas, and the three squamous cell carcinomas completely regressed following irradiation. Two squamous cell carcinomas recurred during the follow-up period. One recurrent squamous cell carcinoma was successfully treated by a salvage surgical operation, and in the other case the patient refused further therapy. In two verrucous carcinomas there was 90% regression of tumour volume. No severe radiation-related complication occurred. (Author)

Full Text Available Adrenal sarcomatoid carcinomas are extremely rare tumors presenting with extensive locoregional spread at the time of diagnosis. Patients succumb to metastases within a couple of months. As a result, very few cases are reported in the literature until now. We present a case of a 62-year old female with non-functional sarcomatoid carcinoma of the right adrenal gland. There was no radiological evidence of locoregional metastases. Patient underwent right adrenalectomy. Follow up after 3 months showed para-aortic lymphadenopathy and similar left adrenal mass on computed tomography. Patient refused further treatment and succumbed to the disease. A brief case report with review of literature is presented.

Full Text Available Background. Basal cell carcinoma (BCC is the most prevalent skin cancer. Because of its highly vascular characteristic, it is amendable to treatment with pulse dye laser (PDL. The goal of this study is to determine the safety and efficacy of PDL therapy for mostly facial BCCs. Materials and Methods. Sixteen men and thirteen women (29 total with 39 biopsy-proven BCCs were treated with 1–4 PDL (595 nm therapies at 2–4-week intervals. The treatment parameters included pulse energy of 15 J/cm 2, pulse length of 3 millisecond, with no dynamic cooling, and 7 mm spot size. The age of the patients was 30–90 years (mean 73 years. Response rates were evaluated by the clinical assessments with mean followup of 11 months. Results. Twenty-four patients with thirty-two tumors reached at least three months followup: 24/32 (75% tumors with complete resolution (mean 3 treatment sessions; 5/32 (16% tumors recurred; 3/32 (9% tumors with incomplete responses after four treatments. Minimal side effects and discomfort were experienced by the patients with PDL therapy. Conclusion. PDL is a safe, tolerable, and moderately effective method of treating various BCCs. The ideal niche and standardized settings for PDL treatment of BCCs are yet to be determined.

Seventy-five patients with medullary thyroid carcinoma (MTC) have been treated at Institut Gustave-Roussy from 1932 to 1979. Of these, 13 patients had distant metastases and received palliative treatment, their median survival was 3 years. Sixty-two patients with MTC limited to the neck received curative treatment: 6 had exclusive external radiotherapy for inoperable disease and 56 were surgically treated: 23 by total thyroidectomy and 33 by partial thyroidectomy. After surgery 29 patients received external radiotherapy for cervical lymph node involvement (25/29) and/or incomplete surgical resection (12/27). The survival rate was 69% at 5 years and 48% at 10 years. The 29 patients who received post-operative cervical radiotherapy had initially more extensive local disease (p<0.05) than the 27 patients treated by surgery alone, nevertheless their survival was slightly higher. No difference in survival rate was observed between patients treated by total thyroidectomy or partial thyroidectomy, among whom only 4 local recurrences occurred. Three of the 6 patients treated with external radiotherapy alone experienced long survival (4, 7 and 10 years) and a fourth is still in clinical remission 4 years after treatment. The effectiveness of chemotherapy in patients with metastases was poor, only one patient out of 6 had a partial remission following a treatment by adriamycin. In the familial form and multiple endocrine neoplasia type II, total thyroidectomy appears to be indicated. In the sporadic cases, partial thyroidectomy is usually sufficient. External radiotherapy is effective in MTC and seems to be able to eradicate small foci of residual tumor; it is indicated when surgical excision is impossible or incomplete

Therapeutic results were analysed in 30 patients with gingival carcinoma irradiated with 60 Co at the Institute of Oncology in Gliwice. Three-year asymptomatic survival rate was 26%. Administration of 1950 rets dose was associated with a high probability of cure and low risk of complications. Tumour diameter exceeding 3 cm, involvement of adjacent anatomical structures and metastases to cervical lymph nodes worsened considerably the prognosis. (author)

A group of 30 patients with adenocarcinoma of the pancreas including some patients with very advanced disease, were treated with the so-called mixed beam modality employing photon treatments three times per week and neutron treatments twice a week. Two hundred Rads or equivalent Rads (RBE 3.3) were given in daily fractions aiming at a total dose of 6000 Rads in 6 to 8 weeks. The treatments were well tolerated and significant palliation was achieved in 26 to 30 cases. Twelve months survival was 33 percent with a median survival of 7 months or 210 days. Treatment techniques and localization procedures are discussed.

1994-01-01

Forty-six patients with T1 and T2 carcinomas of the floor of mouth (FOM), who underwent brachytherapy from February 1979 to March 1991, were reviewed retrospectively. Four of the 46 patients died within 2 years of their initial treatment, without a local recurrence and/or radiation injury. Therefore, they were excluded from the evaluation of two-year local control and radiation injury rate. The two-year local control rate of the remaining 42 patients was 93% (39/42). The rate was 100% (27/27) in patients treated by brachytherapy (BT) alone, and 80% (12/15) in those treated by BT with external radiation (ERT) and chemotherapy. This rate was not elevated from that achieved at a dose of 70 Gy by BT (88%) when a dose of 80 Gy was given by BT with ERT (90%) in the dose-response relationship. According to tumor extension, the local control rates for pelvic-gingival (PG), pelvic (P) and pelvic-lingual (PL) tumors were 75% (6/8), 100% (19/19) and 93% (14/15), respectively. The two-year radiation injury (mandibular exposure) rate was 10% (4/42). The rate was 7% (2/27) in patients treated by BT alone and 13% (2/15) in those treated by BT with ERT, and was greatly elevated from that occurring with a dose of 70 Gy by BT (5%) when a dose of 80 Gy was given by BT with ERT (13%) in the dose-response relationship. According to tumor extention, the radiation injury rates for PG, P and PL tumors were 13% (1/8), 5% (1/19) and 13% (2/15), respectively. In conclusion, BT with ERT did not improve the local control rate of T1 and T2 carcinomas of FOM, and elevated the radiation injury rate greatly. Therefore, we believe that T1 and T2 carcinoma, even when extending to the gingiva, should be treated by BT alone. Multiple cancer incidence in these patients was 28% (13/46), and the incidence of digestive tract cancer was especially high. Therefore, a complete work-up is necessary before treatment and during the follow-up period. (author)

Objective: To evaluate the effect and safety of external carotid artery infusion treatment of recurrent nasopharyngeal carcinoma (NPC). Methods: 20 cases of recurrent NPC (13 male and 7 female, age 36-65 years, mean 50 years) diagnosed by clinical examination (including nasopharyngoscope), serology (VCA-IgA) and imaging (CT, MR) and treated by external carotid artery infusion (trans-femoral) with adriamycin (or epi-adriamycin), cisplatin (or carboplatin), Pingyangmycin and 5-Fluorouracil. Results: Of all the patients, 8 cases (40%) had a complete response (CR), 7 cases (35%) had a partial response (PR). The overall response rate (CR + PR) was 75%. Cumulative survival rates at 1, 3 years were 90% (18/20), 50%(10/20) respectively. No severe side-effects and complications found. Conclusion: External carotid artery infusion (trans-femoral) should be effective and safe in the treatment of recurrent NPC

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

The hyperfractionation in the oropharynx carcinomas treatment: stages III and IV

International Nuclear Information System (INIS)

Pinto, L.H.J.

1990-01-01

From April 1986 until May 1989. 112 patients with stages III and IV oropharynx carcinomas were included in a protocol comparing the use of Hyperfractionation and Conventional Fractionation. The doses were 6600 rad in 33 fractions of 200 rad for the conventional fractionation and 7040 rad in 64 fractions, two fractions of 110 rad per day for the hyperfractionation. As of January 1990 an analysis was performed in 98 patients, with a median follow-up of 14 months. The probability of complete responses in the oropharynx was 74%, with 84% for the hyperfractionation and 64% for the conventional fractionation ( p < 0,05). Survival was improved in 42 months for those patients treated with hyperfractionation: 27% versus 8% (p < 0,05). In patients with lesions out of the base of the tongue and in those with Karnofsky performance status of 50%, 60% and 70%, survival was improved with the use of hyperfractionation (p = 0,02 and p 0,006 respectively. The study demonstrates the superiority of hyperfractionation over the classical fractionation in the treatment of patients with carcinoma of the oropharynx. (author)

Purpose: The Patterns of Care Study (PCS) of patients treated in 1988-89 included 'patterns of treatment planning' for radiotherapy of carcinoma of the uterine cervix. A Consensus Committee of radiation physicists and oncologists established current guidelines and developed questionnaires to assess the treatment planning process (i.e., the general structure, methodology, and tools) of institutions involved in the Patterns of Care Study. This paper reports the findings of the assessment. Methods and Materials: The PCS surveyed 73 radiotherapy facilities, of which 21 are academic institutions (AC), 26 hospital-based facilities (HB), and 26 free-standing centers (FS). In total, 242 cases were assessed with 39% from academic centers, 33% from hospital-based centers, and 28% from free-standing centers. The survey collected treatment planning information such as the use of computed tomography (CT), simulation procedure, contouring of patient outline, tumor or target delineation, identification of critical structures, method of dose prescription (point or isodose), etc. Data was also obtained concerning implant boosts, e.g., radioisotope used, use of midline block for external beam treatment, availability of remote afterloader, practice of interstitial implants, combination with hyperthermia, etc. Results: There is a high degree of compliance relative to the basic treatment planning standards. For example, 171 cases (out of 173) from AC and HB institutions included simulation and 169 used port film; for cases from FS centers, 61 out of 69 involved simulation and 66 out of 69 included port film. Most institutions used linacs (231 out of 242); in five cases, Co-60 units and in six cases betatron was used. In terms of treatment planning, 53% used skin contours, but only 14% had target volume delineation, with AC and HB being slightly more conscientious in these efforts. Critical organs did not appear to be explicitly considered in external beam treatment planning, with only

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

Esophageal carcinoma has a special place in gastrointestinal carcinomas because it contains two main types, namely, squamous cell carcinoma and adenocarcinoma. Carcinoma esophagus patients require some form of palliation because of locally advanced stage or distant metastasis, where it cannot be subjected to curable treatment with surgery and chemoradiation. Many modalities of palliation of dysphagia are available, but the procedure with least morbidity, mortality, and long-term palliation of...

To evaluate the incidence and risk factors of post-treatment intracranial hemorrhage of brain metastases from hepatocellular carcinoma (HCC). Medical records of 81 patients who have been diagnosed of brain metastases from HCC and underwent surgery, radiosurgery and/or whole brain radiotherapy (WBRT) between January 2000 and December 2013 were retrospectively reviewed. Intracranial hemorrhage was present in 64 patients (79%) at the time of diagnosis. Median value of alpha-fetoprotein (AFP) level was 1,700 ng/mL. The Eastern Cooperative Oncology Group (ECOG) performance status for 20 patients was greater than 2. Fifty-seven patients underwent WBRT and the others were treated with surgery and/or radiosurgery without WBRT. During follow-up, 12 events of intracranial hemorrhage after treatment were identified. Three-month post-treatment hemorrhage rate was 16.1%. Multivariate analyses revealed that ECOG performance status, AFP, and WBRT were associated with post-treatment hemorrhage (p = 0.013, 0.013, and 0.003, respectively). Kaplan-Meier analysis showed that 3-month post-treatment hemorrhage rate of new lesion was higher in patients treated without WBRT, although statistical significance was not reached. (18.6% vs. 4.6%; p = 0.104). Ten of 12 patients with post-treatment hemorrhage died with neurologic cause. WBRT should be considered to prevent post-treatment hemorrhage in the treatment of brain metastases from HCC.

Background: in advanced vaginal recurrences of cervical and endometrial carcinomas therapeutic options are rare because of preceding therapy. Patients and methods: 23 patients developing advanced vaginal recurrences of cervical and endometrial carcinomas were included. 15 patients started with external-beam therapy to the pelvis and eight patients after preceding radiotherapy underwent brachytherapy alone. All patients had ultrasound-guided implantation of transvaginal or transperineal interstitial needles for brachytherapy. Median prescribed total dose was 64 Gy. Results: 18 patients (78%) achieved complete remission. Six patients are alive without tumor and one with tumor after a median follow-up of 64 months. 14 patients died of tumor and two of intercurrent disease. 5-year disease-specific survival and local control rate were 43% and 47%, respectively, in patients with complete remission. Univariate analysis found time to relapse > 2 years, initial diameter {<=} 4 cm, initial volume < 15 cm{sup 3}, no extension to the pelvic side wall, volume before brachytherapy < 7.5 cm{sup 3}, brachytherapy coverage index > 0.8, and prescribed total dose > 64 Gy being positive predictors for local control and survival. Conclusion: the use of ultrasound guidance for placement of interstitial needles in template-based brachytherapy of advanced recurrent gynecologic malignancies is a feasible, safe, and cheap method with encouraging results. Today, ultrasound imaging can be also used to some extent for treatment planning which requires further development. Patient- and treatment-related prognostic factors can be defined. (orig.)

2008-04-01

A small percentage of patients with hepatocellular carcinoma (HCC) are candidates for curative treatment in form of resection or transplantation. There are different treatment options for unresectable HCC-like local ablative therapies and recently systemic therapy with Sorafenib. All of these have variable response rate and had been proven to improve survival. In the last few years, there is a growing interest in TheraSphere radioembolization. It consists of yttrium90 (Y-90) embedded into nonbiodegradable glass microspheres. It is selectively administered by intraarterial hepatic injection giving high doses of radiation to the tumor and sparing the liver parenchyma. It has been shown to improve survival and used as a bridge to transplantation and to downstage tumors for resection. Therasphere seems to have favorable safety profile and has been used in patients with portal vein thrombosis with successful outcome.

Full Text Available Man Wu,1,2 Guanren Zhao,2 Xiaomei Zhuang,1 Tianhong Zhang,1 Ce Zhang,2 Wenpeng Zhang,1 Zhenqing Zhang1 1State Key Laboratory of Toxicology and Medical Countermeasures, Beijing Institute of Pharmacology and Toxicology, Beijing, China; 2Department of Pharmacy, The 309th Hospital of PLA, Beijing, China Background: Triclosan is a widely applied antimicrobial agent which affects the endocrine system and homeostasis; it may also promote the cirrhosis and hepatocellular carcinoma (HCC growth in a mice model. The exact roles of triclosan in regulating human hepatocellular carcinoma development and treatment remain unknown. Methods: MHCC97-H, a highly aggressive HCC cell line, was treated with indicated concentration of triclosan or sorafenib. The expression of drug-resistance genes was examined by qPCR. The clearance or metabolism of sorafenib was determined by liquid chromatograph-mass spectrometer/mass spectrometer (LC-MS/MS. MTT assay was used to examine the MHCC97-H cell proliferation. Nude mice were used to exam the anti-tumor effect of sorafenib on subcutaneous and intrahepatic growth of MHCC97-H cells. Results: In the present study, triclosan could induce the expression of drug-resistance genes in MHCC97-H cells (a highly aggressive HCC cell line, accelerate the clearance of sorafenib, and attenuate the anti-proliferation effect of this molecular targeted agent in MHCC97-H cells. Triclosan decreased the antitumor effect of sorafenib on subcutaneous and intrahepatic growth of MHCC97-H in nude mice. Conclusion: By discovering the fact that triclosan treatment enhances sorafenib resistance in HCC cells, this work suggests exposure of triclosan is detrimental to HCC patients during chemotherapy. Keywords: HCC, triclosan, sorafenib resistance, drug clearance

Purpose: Adjuvant radiation therapy (RT) has been shown to improve local control in patients with endometrial carcinoma. We analyzed the impact of the time interval between hysterectomy and RT initiation in patients with endometrial carcinoma. Methods and Materials: In this institutional review board-approved study, we identified 308 patients with endometrial carcinoma who received adjuvant RT after hysterectomy. All patients had undergone hysterectomy, oophorectomy, and pelvic and para-aortic lymph node evaluation from 1988 to 2010. Patients' demographics, pathologic features, and treatments were compared. The time interval between hysterectomy and the start of RT was calculated. The effects of time interval on recurrence-free (RFS), disease-specific (DSS), and overall survival (OS) were calculated. Following univariate analysis, multivariate modeling was performed. Results: The median age and follow-up for the study cohort was 65 years and 72 months, respectively. Eighty-five percent of the patients had endometrioid carcinoma. RT was delivered with high-dose-rate brachytherapy alone (29%), pelvic RT alone (20%), or both (51%). Median time interval to start RT was 42 days (range, 21-130 days). A total of 269 patients (74%) started their RT <9 weeks after undergoing hysterectomy (group 1) and 26% started ≥9 weeks after surgery (group 2). There were a total of 43 recurrences. Tumor recurrence was significantly associated with treatment delay of ≥9 weeks, with 5-year RFS of 90% for group 1 compared to only 39% for group 2 (P<.001). On multivariate analysis, RT delay of ≥9 weeks (P<.001), presence of lymphovascular space involvement (P=.001), and higher International Federation of Gynecology and Obstetrics grade (P=.012) were independent predictors of recurrence. In addition, RT delay of ≥9 weeks was an independent significant predictor for worse DSS and OS (P=.001 and P=.01, respectively). Conclusions: Delay in administering adjuvant RT after

Prognostic factors in the treatment of local advanced hepatocellular carcinoma with radiotherapy, transcatheter arterial embolization and arterial infusion. The treatment effects of radiotherapy and combination modality therapy for the local advanced hepatocellular carcinoma (HCC) were retrospectively reviewed. Three hundred and fifty-six patients of HCC (187 recurrent cases after surgical resection) were treated by: radiotherapy only ; bi-therapeutic method: hepatic artery ligation (HAL) and/or hepatic artery embolization (HAE) plus radiotherapy; and tri-therapeutic method (bi-therapeutic method plus hepatic artery infusion) from 1975 to 1996. Kaplan-Meier method has been used to evaluate the survival rates. There were no significant differences among these three treatment groups in the symptom relied rate, but the mean relief time period was much shorter in radiotherapy alone group (2.5 vs 44 months, P 0.05). There were evident differences in five-year survivals among these three treatment groups: 0 % for radiotherapy alone, 22.8 % for bi-therapeutic method and 38.8 % for tri-therapeutic method (P < 0.01). The prognosis was influenced by Okuda classification. Non-resectable local advanced HCC can be treated by the combination modality therapy, including radiotherapy, with a quite high cure rate. Radiotherapy alone can relief the symptoms. (authors)

Background and purpose: to date none of the studies examined the feasibility and efficacy of interstitial high-dose-rate (HDR) brachytherapy in the treatment of carcinoma of the tongue base. Therefore the aim of this study was to contribute to this issue. Patients and methods: between 1992 and 2000 37 patients (mean age 55 years) with T1-4 and NO-3 carcinoma of the base of tongue were presented. Neck dissection was carried out in twelve cases (32%). 30 patients with advanced stage received brachytherapy boost after 50-66.5 Gy (mean, 60 Gy) locoregional external beam irradiation (EBI) and 7 patients with early stage (T1-2, NO) were managed locally with wide tumor excision and sole brachytherapy. 4 of them underwent neck dissection and the others were subjected to 50 Gy regional EBI. The mean dose of boost and sole brachytherapy was 18 Gy and 28 Gy, respectively. Results: the median follow-up time for surviving patients was 51 months. The 7 sole brachytherapy patients are living with no evidence of disease. For patients treated with EBI and brachytherapy boost, the 5-year actuarial rate of local, locoregional recurrence-free and overall survival was 60%, 52% and 46%, respectively. For all patients in univariate analysis larger tumor size (T4 vs. T1-3) was significant negative predictor of local (RR: 7.23) and locoregional control (RR: 3.87), but nodal involvement was not. Delayed soft tissue ulceration and osteoradionecrosis occurred in 4 (13%) EBI and brachytherapy treated patients. None of the sole brachytherapy patients experienced severe late radiation toxicity. Conclusion: EBI combined with interstitial HDR brachytherapy boost result in acceptable local tumor control with low incidence of late side effects in patients with advanced disease. Fractionated sole HDR brachytherapy following tumor excision is a feasible treatment option for patients with early stage cancer and gives excellent local results. (orig.)

Primary treatment of basal cell carcinoma of the lower eyelid and the inner corner is essentially surgical, but advanced lesions require extensive surgical interventions. In some cases it is necessary to continue with the mutilating surgery--exenteration of the orbit. In this work we evaluate the indications of radical solutions in patients with basal cell carcinoma invading the orbit and the subsequent possibility for individually made prosthesis to cover the defect of the cavity. Indications to exenteration of the orbit in patients with basal cell carcinoma findings in 2008-2013. Case report of 2 patients. In period 2008-20013 at the Dept. of Ophthalmology, Comenius University in Bratislava totally 221 patients with histologically confirmed basal cell carcinoma of the eyelids and the inner corner were treated. In 5 cases (2.7 %) with infiltration of the orbit the radical surgical procedure, exenteration was necessary. In 3 patients exenteration was indicated as the first surgical procedure in the treatment of basal cell carcinoma, since they had never visited ophthalmologist before only at in the stage of infiltration of the orbit (stage T4). In one case was indicated exenteration after previous surgical interventions and relapses. After healing the cavity patients got individually prepared epithesis. Surgical treatment of basal cell carcinoma involves the radical removal of the neoplasm entire eyelid and stage T1 or T2 can effectively cure virtually all tumors with satisfactory cosmetic and functional results. In advanced stages (T4 stage) by infiltrating the orbit by basal cell carcinoma exenteration of the orbit is necessary. This surgery is a serious situation for the patient and also for his relatives. Individually made prosthesis helps the patient to be enrolled to the social environment.

In 31 cases of Stages I or II carcinoma of the breast treated by primary radiation therapy, the cosmetic results were analyzed with regard to the details of treatment. Three principal treatment factors were identified which influenced the cosmetic outcome: (1) the extent and location of the biopsy procedure; (2) the time/dose factors of the radiation therapy; and (3) the technique of the radiation therapy. Cosmetic results were lessened when the biopsy procedure included a wide resection of adjacent breast tissue or when the biopsy scar was obvious. Increasing doses of external beam radiation were associated with greater degrees of retraction and fibrosis of the treated breast. All 6 patients who received 6000 rad by external beam had significant retraction, and fibrosis while patients who received 5000 rad rarely showed significant changes. Local boost doses by interstitial implantation did not diminsh the cosmetic outcome. All patients were treated using supervoltage equipment without bolus and skin changes secondary to treatment were infrequent. Seventeen patients developed localized areas of fibrosis and skin changes at the matchline between adjacent radiation fields. Recommendations are made for improved cosmetic results based on these findings

Coplanar extended-field intensity-modulated radiation therapy (EF-IMRT) targeting the whole-pelvic and para-aortic lymph nodes in patients with advanced cervical cancer results in impaired creatinine clearance. An improvement in renal function cannot be expected unless low-dose (approximately 10 Gy) kidney exposure is reduced. The dosimetric method should be considered during EF-IMRT planning to further reduce low-dose exposure to the kidneys. To assess the usefulness of non-coplanar EF-IMRT with kidney-avoiding beams to spare the kidneys during cervical carcinoma treatment in dosimetric analysis between non-coplanar and coplanar EF-IMRT, we compared the doses of the target organ and organs at risk, including the kidney, in 10 consecutive patients. To estimate the influence of EFRT on renal dysfunction, creatinine clearance values after treatment were also examined in 18 consecutive patients. Of these 18 patients, 10 patients who were included in the dosimetric analysis underwent extended field radiation therapy (EFRT) with concurrent chemotherapy, and eight patients underwent whole-pelvis radiation therapy with concurrent chemotherapy to treat cervical carcinoma between April 2012 and March 2015 at our institution. In the dosimetric analysis, non-coplanar EF-IMRT was effective at reducing low-dose (approximately 10 Gy) exposure to the kidneys, thus maintaining target coverage and sparing other organs at risk, such as the small bowel, rectum, and bladder, compared with coplanar EF-IMRT. Renal function in all 10 patients who underwent EFRT, including coplanar EF-IMRT (with kidney irradiation), was low after treatment, and differed significantly from that of the eight patients who underwent WPRT (no kidney irradiation) 6 months after the first day of treatment (P = 0.005). In conclusion, non-coplanar EF-IMRT should be considered in patients with advanced cervical cancer, particularly in patients with a long life expectancy or with pre-existing renal dysfunction.

Full Text Available We report a case of pleomorphic carcinoma with exon 18 mutation (G719X of the epidermal growth factor receptor (EGFR, which showed good response to afatinib and resulted in successful resection. To our knowledge, this is the first report on the use of afatinib for pleomorphic carcinoma followed by the surgical resection. The patient was a 59-year-old woman, who visited our hospital because chest computed tomography showed a 28 × 28-mm nodule in the left upper lobe. Bronchoscopy was performed and the histological findings of transbronchial biopsy revealed adenosquamous carcinoma positive for G719X mutation in exon 18 of the EGFR. Since fluorodeoxyglucose (FDG-positron emission tomography/computed tomography revealed a positive accumulation in the bilateral hilar and mediastinal lymph nodes, the disease was diagnosed as cT1bN3M0, stage IIIB. After 3 months of afatinib therapy, FDG accumulation in primary tumor was almost gone. However, FDG accumulation in lymph nodes remained unchanged. Video-assisted thoracic surgery was planned for further diagnostic information and left upper lobectomy with mediastinal lymph node dissection was performed. The resected tumor included adenocarcinoma, squamous cell carcinoma, and spindle cell components, without lymph node metastasis. Thus, the disease was diagnosed as pleomorphic carcinoma (pT2aN0M0, stage IB. All components in the resected specimen had the same G719X mutation in exon 18 of the EGFR. The patient has shown no signs of recurrence at 1 year after the operation. The present case indicates the possibility of minor EGFR mutations in pleomorphic carcinoma and successful outcome by the use of afatinib and surgical resection.

Walsh, S

2012-02-01

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

Objective: To evaluate the transarterial chemoembotherapy in the treatment of advanced or late staged digestive tract carcinoma. Methods: One hundred fifty-one patients with advanced or late staged digestive tract carcinoma (including 20 cases of esophageal carcinoma, 29 cases of cardia carcinoma, 71 cases of gastric carcinoma and 31 cases of large intestinal carcinoma) underwent super selective transarterial chemoembotherapy. Results: Interventions were successful. Symptoms were apparently improved in all cases. Decreased diameter of tumor was seen in all cases. Half-year survival rate was 95% (144/151); one year survival was 86% (130/150); two year survival rate was 66% (99/151); and three year survival rate was 29% (44/151). Conclusion: The transarterial chemoembotherapy is an effective treatment of advanced or late staged digestive tract carcinoma. In patients with metastases, the intervention is especially valuable for both primary and metastatic lesions

Purpose: To assess outcome of patients with bilateral breast carcinoma treated with bilateral breast conserving surgery with radiation therapy (CS+RT) and to compare their outcome to (1) patients with unilateral disease treated with CS+RT and (2) patients of comparable stage treated with bilateral mastectomy. Methods and Materials: The charts of all patients with the diagnosis of breast cancer treated with CS+RT at our facilities prior to 1993 were reviewed to identify patients with bilateral disease. A total of 50 patients identified as having bilateral breast cancer conservatively treated(BCT) served as the index population. Out of the 50 patients, 23 presented with synchronous bilateral breast cancer and 27 presented with metachronous bilateral breast cancer. A group of 984 patients with unilateral breast cancer (UCT) treated with CS+RT during the same time interval served as the first control group. A second control group was comprised of 42 patients with early stage bilateral breast cancer presenting during the same time interval treated with bilateral mastectomy (BMAST). Patients who had locally advanced disease in either breast or those patients treated exclusively for lobular carcinoma in situ in either breast were excluded from the analysis. Of the 42 BMAST patients, 33 presented with synchronous disease and nine presented with metachronous disease. Local-regional relapse rates were calculated from the date of treatment of each breast. Overall survival and distant relapse rates were calculated from the date of treatment of the second breast cancer diagnosed. Survival curves were calculated via the life table method and statistical comparisons between curves were performed using the log rank statistic. Chi square analysis was used to detect differences between categorical variables. Results: As of December 1995, the median follow-up of the bilateral conservatively treated patient population was 9.4 years. No statistically significant differences were noted

Sorafenib is the standard of care for patients with advanced hepatocellular carcinoma (HCC) and well preserved liver function. However, until recent approval of regorafenib by the Food and Drug Administration (FDA), no effective therapeutic options were available for patients resistant to sorafenib. Areas covered: The present article reviews the preclinical and clinical data of regorafenib, putting them into the context of current and future landscape of treatment options for patients with HCC. Recently, the randomized, placebo-controlled, Phase III RESORCE trial, demonstrated a statistically and clinically significant increase in overall survival from 7.8 months with placebo to 10.6 months with regorafenib in patients progressing on sorafenib. Furthermore, the study showed a significant improvement in all the other efficacy endpoints. Main adverse events were hypertension, hand-foot skin reaction, fatigue and diarrhea, with no negative impact on quality of life. Expert commentary: Regorafenib is a recently approved treatment option for HCC patients who have been previously treated with sorafenib. The RESORCE trial demonstrates the beneficial effect of a sequential approach involving two multikinase inhibitors, namely sorafenib and regorafenib, whose antitumor activity extends beyond their antiangiogenic functions.

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

PMS2 expression loss was reported in a variety of human. However, its importance has not been fully understood in cervical carcinoma. The aim of this study was to determine the expression of PMS2 in cervical carcinoma and evaluate the significance of mismatch repair gene PMS2 regulated by glycogen synthase kinase 3beta (GSK-3beta) in chemosensitivity. We examined PMS2 and phosphorylated GSK-3beta(s9) expression in cervical carcinoma tissues using immunohistochemical staining. Furthermore, we detected PMS2 expression in HeLa cells and evaluate the interaction with GSK-3beta after transfection with GSK-3beta by small interference RNA (siRNA), co-immunoprecipitation and immunoblotting. We also evaluated the effect of PMS2 transfection on HeLa cells' chemosensitivity to cisplatin treatment. We found significant downregulation of PMS2 in cervical carcinoma, which was negatively associated with phosphorylated GSK-3beta (s9). Furthermore, we demonstrated GSK-3beta transfection was able to interact with PMS2 and enhance PMS2 production in HeLa cells, and increased PMS2 production was responsible for enhanced chemosensitivity. Our results provide the evidence that stabilization of PMS2 production by GSK-3beta was important to improve chemosensitization, indicating the significance of GSK-3beta-related PMS2 downregulation in the development of cervical carcinoma and in developing a potential strategy for chemotherapy.

Adriamycin (doxorubicin, Adriblastin) and cis-diammine-dichloro-platinum (II) (DDP, NSC 119 875) were used in the treatment of 18 patients with ovarian carcinoma, usually after intensive pre-treatment, both in a dosage of 50 mg/m2 once every 4 weeks. Forced diuresis was initiated at the same time. On average three such treatments were given. Six patients showed partial remission defined as decrease of tumour mass by more than 50% or as almost complete disappearance of ascites during more than two months without concomitant diuretic treatment. The remission time was 2+, 3, 3+, 3.5, 7+, and 9+ months. In all patients severe gastrointestinal toxicity occurred, however the myelosuppressive action was only moderate. Nephrotoxicity was negligible. Combined chemotherapy with Adriblastin and DDP thus seems effective even in intensively pretreated patients with ovarian carcinoma.

Inhibition of STAT-3 results in radiosensitization of human squamous cell carcinoma

International Nuclear Information System (INIS)

Bonner, James A.; Trummell, Hoa Q.; Willey, Christopher D.; Plants, Brian A.; Raisch, Kevin P.

2009-01-01

Background: Signal transducer and activator of transcription-3 (STAT-3) is a downstream component of the Epidermal Growth Factor Receptor (EGFr) signaling process that may facilitate the resistance of tumor cells to conventional cancer treatments. Studies were performed to determine if inhibition of this downstream protein produces radiosensitization. Methods/Results: A431 cells (human squamous cell carcinoma cells with EGFr overexpression) were found to be sensitized to radiation after treatment with STAT-3 small interfering RNA (siRNA). Therefore, a short hairpin RNA (shRNA) against STAT-3 was designed and cloned into a pBABE vector system modified for shRNA expression. Following transfection, clone 2.1 was selected for further study as it showed a dramatic reduction of STAT-3 protein (and mRNA) when compared to A431 parental cells or a negative control shRNA cell line (transfected with STAT-3 shRNA with 2 base pairs mutated). A431 2.1 showed doubling times of 25-31 h as compared to 18-24 h for the parental cell line. The A431 shRNA knockdown STAT-3 cells A431 were more sensitive to radiation than A431 parental or negative STAT-3 control cells. Conclusion: A431 cells stably transfected with shRNA against STAT-3 resulted in enhanced radiosensitivity. Further work will be necessary to determine whether the inhibition of STAT-3 phosphorylation is a necessary step for the radiosensitization that is induced by the inhibition of EGFr.

Endoscopic Laser Treatment for Rectosigmoid Villous Adenoma: Factors Affecting the Results

JM Brunetaud

1992-01-01

Full Text Available Endoscopic laser treatment is now commonly used for palliation of advanced digestive cancers in nonsurgical candidates. lt has also been used for treatment of benign rectosigmoid villous adenoma. The present work reports the long term results in 387 patients with benign rectosigmoid villous adenomas revealed by biopsy. Patients included 39% who had contraindications to surgery, 19% who had a tumour recurrence after a nonlaser treatment, 41 % for whom surgical resection appeared to be too drastic for a tumour found benign on biopsy, and 1 % who refused surgery. Two types of wavelength were used: the 1.06 µm infrared light from the Nd:YAG laser and the green light from the argon laser or the Nd:YAG frequency doubled laser. In some patients, both wavelengths were used. Treatment was completed in 343 patients. Total tumour destruction was achieved in 92.8% of patients, a carcinoma was detected in 6.4% on biopsy specimens obtained during laser treatment and benign villous tissue persisted in 0.8%. During the average 30-month follow-up period of the patients with total tumour destruction , 16% had a recurrence. Treatment was well-tolerated with a complication race of 2.3% (one patient with a perforation, one with hemorrhage and seven with stenosis requiring dilation. Circumferential extension of the tumour base was the only factor affecting the duration of treatment, the rate of cancers detected during treatment and the rate of complications. Recurrence rate after initial treatment was higher in patients treated for a recurrence after a previous nonlaser treatment than in patients treated only by laser (P<0.01. It was also higher when the initial histology showed low grade dysplasia as opposed to high grade dysplasia (P<0.01 and when the tumour was located in the lower or middle rectum rather than in the upper rectum or sigmoid (P<0.01. Direct cost of laser treatments was estimated to be 28 to 40% of the surgery charges for lesions of identical size

Full Text Available Photodynamic therapy has shown promise in the treatment of early head and neck squamous cell carcinoma (SCC. In photodynamic therapy (PDT, a light sensitive drug (photosensitizer and visible light cause cancer cell death by the creation of singlet oxygen and free radicals, inciting an immune response, and vascular collapse. In this paper, we review several studies that demonstrate the effectiveness of PDT in the treatment of early stage SCC of the head and neck, with some showing a similar response rate to surgery. Two cases are presented to illustrate the effectiveness of PDT. Then, new advances are discussed including the discovery of STAT3 crosslinking as a potential biomarker for PDT response and interstitial PDT for locally advanced cancers.

Purpose: To compare the safety of image-guided percutaneous cryoablation and radiofrequency ablation in the treatment of hepatocellular carcinoma in patients with cirrhosis. Materials and methods: This retrospective HIPAA-compliant study received institutional review board approval. Forty-two adult patients with cirrhosis underwent image-guided percutaneous ablation of hepatocellular carcinoma from 2003 to 2011. Twenty-five patients underwent 33 cryoablation procedures to treat 39 tumors, and 22 underwent 30 radiofrequency ablation procedures to treat 39 tumors. Five patients underwent both cryoablation and radiofrequency ablation procedures. Complication rates and severity per procedure were compared between the ablation groups. Potential confounding patient, procedure, and tumor-related variables were also compared. Statistical analyses included Kruskal–Wallis, Wilcoxon rank sum, and Fisher's exact tests. Two-sided P-values <0.05 were considered significant. Results: The overall complication rates, 13 (39.4%) of 33 cryoablation procedures versus eight (26.7%) of 30 radiofrequency ablation procedures and severe/fatal complication rates, two (6.1%) of 33 cryoablation procedures versus one (3.3%) of 30 radiofrequency ablation procedures, were not significantly different between the ablation groups (both P = 0.26). Severe complications included pneumothoraces requiring chest tube insertion during two cryoablation procedures. One death occurred within 90 days of a radiofrequency ablation procedure; all other complications were managed successfully. Conclusion: No significant difference was seen in the overall safety of image-guided percutaneous cryoablation and radiofrequency ablation in the treatment of hepatocellular carcinoma in patients with cirrhosis

Bokhman, Ya.V.; Kuznetsov, V.V.

1981-01-01

A group of patients with uterine cervix carcinoma with metastatic indices in regional lymphatic vessels detected on lymphograms is studied. It is established that after radiation treatment the relative resistance of lymphogenic metastases to the ionizing radiation is found in 14.9% patients. Extraperitoneal removal of regional lymphatic collectors after a complete course of combined radiation therapy in patients with uterine cervix carcinoma with histologically proved metastases improves 3-year results of survival up to 40%. In the case of multiple and bilateral metastatic injury of regional lymph nodes the therapeutic value of extraperitoneal lymphadenectomy reduces sharply. The diagnostic value of X-ray contrast lymphography not only for defining regional metastases, but for planning and carrying out the treatment of patients with uterine cervix carcinoma is pointed out [ru

Forty-four patients with squamous cell carcinoma of the penis stage T1-T2, N0 were either treated surgically (n=19) or with a combination of irradiation and bleomycin (n=25). 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.)

Eighty-two patients with advanced well-differentiated thyroid carcinoma were treated. Sixty-six patients survived for more than 10 years and 10-year-survival rate was 80.5 %. Multidisciplinary treatment, consisting of surgery, radioiodine, external irradiation and TSH suppression was studied. We emphasized that radioiodine treatment after thyroid-ectomy was unique and an ideal therapeutic model for locally advanced, distant metastatic and recurrent cases as far as radioiodine was accumulated on thyroid cancer tissue. External irradiation was sometimes effective for the remnant thyroid carcinoma and metastases. Occassionally, well-differentiated thyroid carcinoma showed good response to TSH suppression therapy using thyroid hormone. The significance of conversion of well-differentiated carcinoma of thyroid to anaplastic carcinoma was noticed. We recognized that radiation therapy was effective for advanced well-differentiated thyroid carcinoma in multidisciplinary treatment. (author)

Objective: To analyze the optimum method of radiotherapy for loco-regional recurrence in 45 patients after surgery for esophageal carcinoma. Methods: From June 1993 to June 1999, 45 such patients were treated by radiotherapy. Eleven patients had recurrent lesions in the supraclavicular region, 23 in the mediastinum, 5 in both mediastinum plus supraclavicular area and 6 in mediastinum plus anastomotic orifice. A total dose of 50-80 Gy was given. Nineteen patients received FP (5-Fu+DDP) chemotherapy after radiotherapy. Results: The medium survival was 12 months and the 1-, 2- and 3-year survival rates were 51.1%, 26.7% and 11.1%. For those who received R+C and R only, the 3-year survival rates were 21.1% and 3.9%, showing a conspicuous raise in the survival although P>0.05. Multi-variate analysis showed that post-surgical staging (P=0.023) and radiotherapy (P=0.002) were closely related to prognosis. Conclusion: Among the various methods of treating loco-regional recurrence after surgery of esophageal carcinoma, commonly yielding poor results, radiotherapy is still the method of choice. A total dose of >60 Gy is able to effect a good loco-regional control as well as a good result

Purpose: To assess the role of radiotherapy alone or in combination with surgery in the treatment of patients with malignant minor salivary gland carcinomas. Methods and Materials: Between October 1964 and November 1992, 95 patients with minor salivary gland carcinomas of the head and neck received radiotherapy with curative intent. Eighty-seven patients were previously untreated, and 8 were treated for postsurgical recurrence. Fifty-one patients were treated with radiotherapy alone, and 44 were treated by surgical resection plus radiotherapy. Patients were staged according to the 1983 American Joint Committee on Cancer (AJCC) staging criteria for squamous cell carcinomas. Results: The 20-year actuarial rate of local control was 57% with no significant difference according to histologic type. When tumor stage was taken into consideration, there were no significant differences in local control according to tumor site. The 12-year actuarial probability of distant metastases was 40% (19% as the only site of failure). In multivariate analyses, local control was significantly affected only by tumor stage and treatment type (combined therapy better than radiotherapy alone); tumor stage was a significant predictor of cause-specific survival and freedom from relapse. Freedom-from-relapse rates were higher for patients who received combined treatment (p = 0.068). Conclusions: Treatment of minor salivary gland carcinomas is usually by combined surgery and radiotherapy, but there are situations where surgery alone or radiotherapy alone may be used. The ability to control these tumors with radiotherapy alone is not widely recognized. In the present series, the tumor was locally controlled in 20 patients with previously untreated primary lesions after radiotherapy alone (2.5 to 21 years) and in 4 other patients who were treated by radiotherapy alone for postsurgical recurrent tumor (3.5 to 14 years after radiotherapy). Contrary to the widely held belief that local recurrence

Purpose: To evaluate the impact of both adjuvant and definitive radiotherapy on local control of adrenocortical carcinoma. Methods and Materials: Outcomes were analyzed from 58 patients with 64 instances of treatment for adrenocortical carcinoma at the University of Michigan's Multidisciplinary Adrenal Cancer Clinic. Thirty-seven of these instances were for primary disease, whereas the remaining 27 were for recurrent disease. Thirty-eight of the treatment regimens involved surgery alone, 10 surgery plus adjuvant radiotherapy, and 16 definitive radiotherapy for unresectable disease. The effects of patient, tumor, and treatment factors were modeled simultaneously using multiple variable Cox proportional hazards regression for associations with local recurrence, distant recurrence, and overall survival. Results: Local failure occurred in 16 of the 38 instances that involved surgery alone, in 2 of the 10 that consisted of surgery plus adjuvant radiotherapy, and in 1 instance of definitive radiotherapy. Lack of radiotherapy use was associated with 4.7 times the risk of local failure compared with treatment regimens that involved radiotherapy (95% confidence interval, 1.2-19.0; p = 0.030). Conclusions: Radiotherapy seems to significantly lower the risk of local recurrence/progression in patients with adrenocortical carcinoma. Adjuvant radiotherapy should be strongly considered after surgical resection.

Purpose: To analyze the results of radical radiotherapy by electron beams for squamous cell carcinoma (SCC) of the eyelid and to find the possible prognostic factors. Materials and Methods: Records of 38 patients with histologically confirmed SCC of the eyelid who underwent electron beam radiation therapy between 1964 and 2010 in our institution were retrospectively reviewed. Median tumor size was 15 mm (range, 3–40 mm). T stage was T1 in three, T2a in six, T2b in 14, and T3a in 15 patients. Four patients had nodal metastasis. Of the 38 patients, 14 had relapsed disease after prior treatment. Median radiation dose was 60.0 Gy (range, 45.0–70.4 Gy). Median follow-up was 72.5 months (range, 2.0–369 months). Results: 5-year local relapse-free, nodal relapse-free, distant metastasis-free and relapse-free rates for all patients were 71.8%, 77.5%, 90.6% and 58.0%, respectively. In seven patients, lymph node metastases occurred in 11 faciocervical regions. The 5-year overall survival was 79.5%. T stage and radiation dose expressed in EQD 2 Gy tended to have impacts on local control. Relapsed patients showed unfavorable local relapse-free rate, however this was without statistical significance. Of the 14 patients who died, 12 succumbed to concurrent diseases. Grade 3 or greater severe late morbidities (CTCAE ver4.0) were observed in nine patients. Due to the morbidities, two patients lost their vision. Conclusion: Radical radiotherapy for SCC of the eyelid yielded good results and could be a treatment option. Whether radiation-dose escalation could improve local control in advanced T stages and relapsed patients needs further study

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

A bibliographic review was conduced on the use of 5-methyl aminolevulinate in dermatology, specifically in the treatment of actinic keratosis, epidermoid carcinoma and basal cell carcinoma. The basic fundamentals of photodynamic therapy are described. The preparation and method of use of photodynamic therapy with 5-methyl aminolevulinate (MAL-PDT) are detailed. The clinical studies that were realized with photodynamic therapy for the treatment of actinic keratosis, epidermoid carcinoma and basal cell carcinoma are mentioned. Different photo-inducible agents and other current therapeutic options of first-line are compared. The MAL-PDT has have the advantage of to present less side effects and the same have been more tolerable than liquid nitrogen and 5 fluorouracil. The MAL-PDT has been considered as an effective option for the treatment of Bowen's disease. Invasive epidermoid carcinoma has existed without evidence to support the routine use of this therapeutic. For superficial basal cell carcinoma, the MAL-PDT has presented a high cure rate and transient and manageable side effects in extensive and multiple lesions. The MAL-PDT has been an effective and safe treatment in patients with basal cell carcinoma, for those with less depth of 2mm. The MAL-PDT could play an important role in the field of prevention with immunosuppressed patients, particularly, those that have required transplant and its immunosuppression has been pharmacological. The use or not of the MAL-PDT, should be evaluated individually for each patient and to have suitable characteristics for each disease that was cited in this review. The photodynamic therapy with 5-methyl aminolevulinate has been a therapeutic modality of considerable economy, however, it should be evaluated in the context of number of inquiries and side effects that have offered other therapeutic modalities [es

Radioactive iodine (/sup 131/I) was used in the treatment of a 12-year-old female dog with hyperthyroidism resulting from a large, unresectable (and metastatic) thyroid carcinoma associated with signs of severe inspiratory stridor and dyspnea. Hyperthyroidism was diagnosed on the basis of clinical signs (polyuria, polydipsia, polyphagia, weight loss, nervousness) and high basal serum thyroxine (T4) concentrations, as well as thyroid radioiodine kinetic studies that showed a high radioiodine uptake into the thyroid (% thyroid uptake) and markedly increased serum concentrations of protein-bound iodine-131 (PB/sup 131/I) after /sup 131/I tracer injection. Thyroid imaging revealed diffuse radionuclide accumulation by the tumor, which involved both thyroid lobes. The dog was treated with three large doses of radioiodine (/sup 131/I), ranging from 60 to 75 mCi, given at intervals of 5 to 7 months. The dog became euthyroid, and the size of the tumor decreased by approximately 25% after each /sup 131/I treatment, improving the severe inspiratory stridor and dyspnea, but both the hyperthyroid state and breathing difficulty recurred within a few months of each treatment. The dog was euthanatized 5 months after the last treatment because of progressive tracheal compression and pulmonary metastasis.

Introduction Efficacious chemotherapy does not exist for treatment or prevention of prostate, liver, and pancreatic carcinomas, and some other cancers that exhibit decreased zinc in malignancy. Zinc treatment offers a potential solution; but its support has been deterred by adverse bias. Areas covered 1. The clinical and experimental evidence for the common ZIP transporter/Zn down regulation in these cancers. 2. The evidence for a zinc approach to prevent and/or treat these carcinomas. 3. The issues that introduce bias against support for the zinc approach. Expert opinion ZIP/Zn downregulation is a clinically established common event in prostate, hepatocellular and pancreatic cancers. 2. Compelling evidence supports the plausibility that a zinc treatment regimen will prevent development of malignancy and termination of progressing malignancy in these cancers; and likely other carcinomas that exhibit decreased zinc. 3. Scientifically-unfounded issues that oppose this ZIP/Zn relationship have introduced bias against support for research and funding of a zinc treatment approach. 4. The clinically-established and supporting experimental evidence provide the scientific credibility that should dictate the support for research and funding of a zinc approach for the treatment and possible prevention of these cancers. 5. This is in the best interest of the medical community and the public-at-large. PMID:27885880

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

We report our institutional observations of ten patients with advanced hepatocellular carcinoma (HCC) (seven and three were Child-Pugh class A and B, respectively) who received compassionate regorafenib therapy between June 2016 and January 2017. These patients did not fit the rigid criteria of a clinical trial and represented the use of regorafenib in an everyday clinic situation. Regorafenib (160 mg P.O. daily) was administered to patients on a 4-week cycle (3 weeks on, 1 week off) until disease progression (assessed using mRECIST criteria) or discontinuation secondary to toxicity (assessed using CTCAE criteria). Relevant clinical data were abstracted from patient medical records and reviewed retrospectively. The median duration of patient treatment was 6.6 weeks, and the median time to disease progression was 12.5 weeks. Most common treatment emergent adverse events were fatigue, diarrhea, and hand-foot skin reaction. Elevated AST and ALT were the most commonly observed laboratory-assessed adverse events, which reached grade 3 status in the Child-Pugh class B patients only. We observed intolerance to regorafenib treatment in one patient who had previously received a liver transplant. We also saw lithium toxicity in one patient receiving long-term lithium treatment, suggesting a potential and unexpected drug-drug interaction with regorafenib. Taken together, our observations indicate that regorafenib is beneficial in the treatment of patients with advanced HCC who progressed on or demonstrated intolerance to sorafenib therapy; however, careful selection and close monitoring of patients is necessary to maximize the benefit while minimizing the toxicities of regorafenib treatment.

Full Text Available Hepatocellular carcinoma (HCC is one of the most common malignant tumors worldwide, and traditional surgery and chemotherapy provide limited benefit. Sorafenib, a multikinase inhibitor, was proved effective for advanced HCC in phase III clinical trial, which was a breakthrough in the treatment of HCC. In recent years, the studies on sorafenib combined with other therapies in the treatment of HCC have been conducted around the world, and inspiring results have been seen. The research advances in sorafenib combined with orthotopic liver transplantation, radiofrequency ablation, and transarterial chemoembolization in the treatment of HCC are summarized. It is thought that sorafenib combined with other anticancer therapies is expected to become a new approach of targeted therapy of HCC.

Purpose/Objective: To determine the role of radiation therapy and chemotherapy in the treatment of Merkel Cell Carcinoma (MCC), a highly aggressive skin tumor. Materials and Methods: A retrospective analysis of 27 patients treated at the Rabin Medical Center in Israel is presented. Data on 40 patients, including 13 additional patients from the Israel Cancer Registry, were analyzed for prognostic factors using uni- and multivariate analysis. Results: Univariate analysis revealed regional lymph node involvement and coexistence of secondary primary as unfavorable prognostic factors. In multivariate analysis only lymph node involvement showed borderline statistical significance. Radiation therapy was highly effective when given as consolidation after surgery or chemotherapy. In 11 patients irradiated prophylactically only one in-field relapse (9%) occurred. Radiation therapy yielded responses in 15 of 15 measurable sites (5CR, 10 PR). Chemotherapy produced responses in 18 of 26 treatments (70%), mostly CR (41%). However, in the absence of radiation therapy the responses were of short duration. Conclusion: Our data support combined treatment with chemotherapy followed by irradiation for advanced loco-regional disease. Further large scale investigations are warranted to confirm this approach

SQUAMOUS CELL CARCINOMA OF THE HEAD AND NECK: NEW AVENUES OF TREATMENT?

Full Text Available Squamous cell carcinoma of the head and neck counts for 3 % of all cancers in men and half of this number less in women with a 5-year survival of 61 %. While the number of laryngeal carcinoma is decreasing, carcinoma of the oral cavity related to an infection by the human papilloma virus (HPV, high-risk subtypes is increasing, especially in younger patients. HPV related squamous cell carcinomas show better survival data, especially in regard to recurrence free rates or secondary carcinoma of adjacent locations. Squamous cell carcinomas related to the presence of HPV DNA material is almost exclusively found in carcinoma of the oral cavity and oropharyngeal mucosa. Much less frequently HPV is present in hypopharyngeal carcinomas and even less number of cases of squamous cell carcinoma with proof for HPV in the nasopharynx and larynx. In case of evidence for HPV DNA; most cases are positively tested for subtype 16, followed by subtype 18. As a surrogate immunhistochemical marker, p16 INK4A is stained positive, cytoplasmic and nuclear. In a small study by ourselves, we found a positive correlation in 100 % of p16 INK4A positivity and positive HPV testing. Oral squamous cell carcinoma is more frequently related to HPV in patients below 50 years of age with a prevalence of ca. 20 %. Whilst HPV high-risk positive carcinomas show very few mutations in single signalling molecules of the downstream receptor tyrosin kinase pathways, HPV negative carcinomas show in many cases a chaotic DNA mutation type with typical mutations in tumor suppressor genes, as p53 and CDKN2A. This pattern is often seen in carcinoma types develop from a summation of accidental mutations often caused by toxins (e.g. inhaled cigarette smoke. However, it is discussed and under investigation whether a subset of head and neck squamous cell carcinomasdevelop from so called driver mutations, as are called mutations in critical members of signalling pathways and receptor tyrosin kinases

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

Advances in imaging diagnostics have contributed to the frequent detection of small kidney tumours both at an early stage and of low grade. Although radical nephrectomy is still the gold standard in Renal Cell Carcinoma (RCC) treatment, yet it slowly ceases to be the standard approach and open or laparoscopic Nephron Sparing Surgery (NSS) is becoming more and more common. Ai m. The purpose of the study was to determine the functional and oncological outcomes of NSS for RCC basing on an analysis of 108 patients. Material and methods. The patients were divided into two groups: T1a (≤ 4 cm) and T1b (≥ 4 ≤ 7 cm). We performed an analysis of all patients with a minimal follow-up time of 24 months. In the majority of patients the diagnosis was clear cell carcinoma(83.9%). Results. G2 tumours were the most common (51.7%). The cumulative proportion of survivors without local relapse within the operated kidney and/or in the local lymph nodes and without distant metastases after 2 and 3 years was 99% and 93%, respectively. Our results support the fact that in pT1a and pT1b patients NSS is a safe and effective procedure. The size of pT1 tumours has no bearing on 2-year and 3-year recurrence-free survivals. Conclusion. Intraoperative ultrasound allows for further identification of additional neo plasmatic foci and for the use of the best surgical approach. Intraoperative ultrasound is useful in NSS, and especially in those cases, where the tumor lies in the central part of the kidney. (authors)

Background - Squamous cell carcinoma of the esophagus is still a difficult tumor to treat with very poor prognosis. Aim - To compare the response to teletherapy treatment (external beam radiotherapy) alone versus teletherapy combined with brachytherapy for patients with advanced squamous cell carcinoma of the esophagus. Methods - Were studied 49 patients with advanced squamous cell carcinoma of the esophagus on clinical stage III (TNM-1999). They were separated into two groups. The first, underwent radiation therapy alone with linear accelerator of particles, average dose of 6000 cGy and the second to external beam radiation therapy at a dose of 5040 cGy combined with brachytherapy with Iridium 192 at a dose of 1500 cGy. Brachytherapy started one to two weeks after the end of teletherapy, and it was divided into three weekly applications of 500 cGy. Age, gender, race, habits (smoking and drinking), body mass index (BMI), complications with treatment benefits (pain relief and food satisfaction) and survival were analyzed. Results - The quality of life (food satisfaction, and pain palliation of dysphagia) were better in the group treated with external beam radiation therapy combined with brachytherapy. Survival was higher in the brachytherapy combined with external beam radiation therapy alone. Conclusion - Although the cure rate of squamous cell cancer of the esophagus is almost nil when treated with irradiation alone, this therapy is a form of palliative treatment for most patients in whom surgical contraindication exists.
