    Purpose: The optimal sequence of radiotherapy and chemotherapy in breast-conserving therapy is unknown. Methods and Materials: From 1983 through 2007, a total of 641 patients with 653 instances of breast-conserving therapy (BCT), received both chemotherapy and radiotherapy and are the basis of this analysis. Patients were divided into three groups. Groups A and B comprised patients treated before 2005, Group A radiotherapy first and Group B chemotherapy first. Group C consisted of patients treated from 2005 onward, when we had a fixed sequence of radiotherapy first, followed by chemotherapy. Results: Local control did not show any differences among the three groups. For distant metastasis, no difference was shown between Groups A and B. Group C, when compared with Group A, showed, on univariate and multivariate analyses, a significantly better distant metastasis-free survival. The same was noted for disease-free survival. With respect to disease-specific survival, no differences were shown on multivariate analysis among the three groups. Conclusion: Radiotherapy, as an integral part of the primary treatment of BCT, should be administered first, followed by adjuvant chemotherapy.

    The use of targeted intraoperative radiotherapy (TARGIT-IORT) as a tumour bed boost during breast-conserving surgery (BCS) for breast cancer has been reported since 1998. We present its use in patients undergoing breast conservation following neoadjuvant therapy (NACT). In this retrospective study involving 116 patients after NACT we compared outcomes of 61 patients who received a tumour bed boost with IORT during lumpectomy versus 55 patients treated in the previous 13 months with external (EBRT) boost. All patients received whole breast radiotherapy. Local recurrence-free survival (LRFS), disease-free survival (DFS), distant disease-free survival (DDFS), breast cancer mortality (BCM), non-breast cancer mortality (NBCM) and overall mortality (OS) were compared. Median follow up was 49 months. The differences in LRFS, DFS and BCM were not statistically significant. The 5-year Kaplan-Meier estimate of OS was significantly better by 15% with IORT: IORT 2 events (96.7%, 95%CI 87.5-99.2), EBRT 9 events (81.7%, 95%CI 67.6-90.1), hazard ratio (HR) 0.19 (0.04-0.87), log rank p = 0.016, mainly due to a reduction of 10.1% in NBCM: IORT 100%, EBRT 89.9% (77.3-95.7), HR (not calculable), log rank p = 0.015. The DDFS was as follows: IORT 3 events (95.1%, 85.5-98.4), EBRT 12 events (69.0%, 49.1-82.4), HR 0.23 (0.06-0.80), log rank p = 0.012. IORT during lumpectomy after neoadjuvant chemotherapy as a tumour bed boost appears to give results that are not worse than external beam radiotherapy boost. These data give further support to the inclusion of such patients in the TARGIT-B (boost) randomised trial that is testing whether IORT boost is superior to EBRT boost. (orig.)

    We compared concurrent combination chemoradiotherapy and adjuvant radiotherapy after laser surgery in patients with stage 3/4 non metastatic squamous cell head and neck cancer. Combination chemotherapy and concurrent irradiation after laser surgery was not superior to surgery and postoperative radiotherapy for resectable advanced squamous cell head and neck cancer. However, the collective is small, and the follow-up to short to conclude. (authors)

    The optimal treatment of advanced maxillary sinus cancer has been challenging for several decades. Intra-arterial chemotherapy (IAC) for head and neck cancer has been controversial. We have analyzed the long-term outcome of neoadjuvant IAC followed by radiation therapy (RT) and surgery. Twenty-seven patients with advanced maxillary sinus cancer were treated between 1989 and 2002. Five-fluorouracil (5-FU, 500 mg/m2) was infused intra-arterially, and followed by RT (total 50.4 Gy/28 fractions). A planned surgery was performed 3 to 4 weeks after completion of IAC and RT. At a median follow-up of 77 months (range, 12 to 169 months), the 5-year rates of overall survival in all patients were 63%. The 5-year rates of overall survival of stage T3/T4 patients were 70.0% and 58.8%, respectively. Seven of fourteen patients with disease recurrence had a local recurrence alone. The 5-year actuarial local control rates in patients with stage T3/T4, and in all patients were 20.0%, 32.3%, and 27.4%, respectively. Overall response rate after the completion of IAC and RT was 70.3%. During the follow-up, seven patients (25.9%) showed mild to moderate late complications. The tumor extent (i.e., the involvement of either orbit and/or base of skull) appeared to be related with local recurrence. Neoadjuvant IAC with 5-FU followed by RT and surgery may be effective to improve local tumor control in the patients with advanced maxillary sinus cancer. However, local failure was still the major cause of death. Further investigations are required to determine the optimal treatment schedule, radiotherapy techniques and chemotherapy regimens.

    Purpose: To evaluate the treatment outcome and efficacy of regional lymph node irradiation after neoadjuvant chemotherapy (NCT) and surgery in positron emission tomography (PET)-positive clinical N3 (cN3) breast cancer patients. Methods and Materials: A total of 55 patients with ipsilateral infraclavicular (ICL), internal mammary (IMN), or supraclavicular (SCL) lymph node involvement in the absence of distant metastases, as revealed by an initial PET scan, were retrospectively analyzed. The clinical nodal stage at diagnosis (2002 AJCC) was cN3a in 14 patients (26%), cN3b in 12 patients (22%), and cN3c in 29 patients (53%). All patients were treated with NCT, followed by mastectomy or breast-conserving surgery and subsequent radiotherapy (RT) with curative intent. Results: At the median follow-up of 38 months (range, 9-80 months), 20 patients (36%) had developed treatment failures, including distant metastases either alone or combined with locoregional recurrences that included one ipsilateral breast recurrence (IBR), six regional failures (RF), and one case of combined IBR and RF. Only 3 patients (5.5%) exhibited treatment failure at the initial PET-positive clinical N3 lymph node. The 5-year locoregional relapse-free survival, disease-free survival (DFS), and overall survival rates were 80%, 60%, and 79%, respectively. RT delivered to PET-positive IMN regions in cN3b patients and at higher doses ({>=}55 Gy) to SCL regions in cN3c patients was not associated with improved 5-year IMN/SCL relapse-free survival or DFS. Conclusion: NCT followed by surgery and RT, including the regional lymph nodes, resulted in excellent locoregional control for patients with PET-positive cN3 breast cancer. The primary treatment failure in this group was due to distant metastasis rather than RF. Neither higher-dose RT directed at PET-positive SCL nodes nor coverage of PET-positive IMN nodes was associated with additional gains in locoregional control or DFS.

    Purpose: to prospectively assess health-related quality of life (HR-QoL) in women after conserving surgery for breast cancer during/after postoperative 3-D radiotherapy. Patients and methods: 109 consecutively treated patients were analyzed. HR-QoL was assessed at initiation (t1), end (t2), and 6 weeks after radiotherapy (t3) using the EORTC modules QLQ-C30/BR23. Patients were divided into three therapy groups. Group I comprised 41 patients (radiotherapy and adjuvant chemotherapy), group II 45 patients (radiotherapy and adjuvant hormonal therapy), and group III 23 patients (radiotherapy alone). Reliability was tested. Scale means were calculated. Univariate (ANOVA) and multivariate (MANCOVA) analyses were performed. Results: reliability testing revealed mean Cronbach's {alpha} > 0.70 at all measurement points. ANOVA/MANCOVA statistics revealed significantly better HR-QoL for patients in group II versus I. Patients receiving radiotherapy alone (group III) showed the best results in HR-QoL. However, scale mean differences between groups II and III were not significant. Conclusion: HR-QoL measurement using EORTC instruments during/after radiotherapy is reliable. Adjuvant chemotherapy significantly lowered HR-QoL versus hormones or radiotherapy alone. Chemotherapy patients did not recover longitudinally (from t1 to t3). (orig.)

    Objective: to identify prognostic factors and evaluate the clinical outcome of patients with glioblastoma treated with surgery and radiotherapy combined or not with chemotherapy. Material and method: in this retrospective study, 48 patients with glioblastoma were treated between 1997 and 2007. All patients were classified according the recursive partitioning analysis (RPA) criteria. Results: the majority of patients were female, with 50 years of age or above. Performance status of 70 or greater were found in 70.8% of cases, and RPA classes V and VI prevailed. Seventy-two percent of patients were submitted to partial resection and 27.1% to total or subtotal resection. Chemotherapy was administered in 47.9% of patients and doses between 50 and 60 Gy were delivered in 72.9%. The median overall survival was 52 weeks. Conclusion: our data show an overall survival that approaches the related in others reports and were dependent of factors such as chemotherapy, dose of radiation and Karnofsky performance status.

    Gliomas, the most common primary brain tumors, are diffusive and highly invasive. The standard treatment for brain tumors consists of a combination of surgery, radiation therapy and chemotherapy. Over the past few years, mathematical models have been applied to study untreated and treated brain tumors. In an effort to improve treatment strategies, we consider a simple spatio-temporal mathematical model, based on proliferation and diffusion, that incorporates the effects of radiotherapeutic and chemotherapeutic treatments. We study the effects of different schedules of radiation therapy, including fractionated and hyperfractionated external beam radiotherapy, using a generalized linear quadratic (LQ) model. The results are compared with published clinical data. We also discuss the results for combination therapy (radiotherapy plus temozolomide, a new chemotherapy agent), as proposed in recent clinical trials. We use the model to predict optimal sequencing of the postoperative (combination of radiotherapy and adjuvant, neo-adjuvant or concurrent chemotherapy) treatments for brain tumors.

    Full Text Available Introduction/Aim. Lung cancer is a leading cause of mortality among patients with carcinomas. The aim of this study was to point out risk factors for brain metastases (BM appearance in patients with IIIA (N2 stage of nonsmall cell lung cancer (NSCLC treated with three-modal therapy. Methods. We analyzed data obtained from 107 patients with IIIA (N2 stage of NSCLC treated surgically with neoadjuvant therapy. The frequency of brain metastases was examined regarding age, sex, histological type and the size of tumor, nodal status, the sequence of radiotherapy and chemotherapy application and the type of chemotherapy. Results. Two and 3-year incidence rates of BM were 35% and 46%, respectively. Forty-six percent of the patients recurred in the brain as their first failure in the period of three years. Histologically, the patients with nonsquamous cell lung carcinoma had significantly higher frequency of metastases in the brain compared with the group of squamous cell lung carcinoma (46% : 30%; p = 0.021. Examining treatment-related parameters, treatment with taxane-platinum containing regimens was associated with a lower risk of brain metastases, than platinum-etoposide chemotherapy regimens (31% : 52%; p = 0.011. Preoperative radiotherapy, with or without postoperative treatment, showed lower rate of metastases in the brain compared with postoperative radiotherapy treatment only (33% : 48%; p = 0.035. Conclusion. Brain metastases are often site of recurrence in patients with NSCLC (IIIA-N2. Autonomous risk factors for brain metastases in this group of patients are non-squamous NSCLC, N1-N2 nodal status, postoperative radiotherapy without preoperative radiotherapy.

    The metastasis of uterine leiomyosarcoma to the neck node has not been reported previously and the radiotherapy has been rarely used for the metastatic lesion of the other sites. We report a case of neck metastasis from a uterine leiomyosarcoma, which developed 10 months after surgery and postoperative pelvic radiotherapy. It also involved the parapharyngeal space, adjacent spine, and spinal canal. The metastatic neck mass was inoperable, and was treated by neck radiotherapy (6,000 cGy) and chemotherapy including taxol and carboplatin. The mass has regressed progressively to a nearly impalpable state. She has never developed spinal cord compression syndrome, and has maintained good swallowing for eight months since the neck radiotherapy and chemotherapy. Since the extensive metastatic neck mass showed good local response to high dose radiotherapy and chemotherapy, both treatments may be considered for an unresectable metastatic leiomyosarcoma.

    Full Text Available Abstract Background Induction chemotherapy (ICT with docetaxel, cisplatin and fluorouracil (TPF followed by radiotherapy is an effective treatment option for unresectable locally advanced head and neck cancer. This phase I study was designed to investigate the safety and tolerability of a split-dose TPF ICT regimen prior to surgery for locally advanced resectable oral and oropharyngeal cancer. Methods Patients received TPF split on two dosages on day 1 and 8 per cycle for one or three 3-week cycles prior to surgery and postoperative radiotherapy or radiochemotherapy. Docetaxel was escalated in two dose levels, 40 mg/m2 (DL 0 and 30 mg/m2 (DL −1, plus 40 mg/m2 cisplatin and 2000 mg/m2 fluorouracil per week using a 3 +3 dose escalation algorithm. Results Eighteen patients were enrolled and were eligible for toxicity and response. A maximum tolerated dose of 30 mg/m2 docetaxel per week was reached. The most common grade 3+ adverse event was neutropenia during ICT in 10 patients. Surgery reached R0 resection in all cases. Nine patients (50% showed complete pathologic regression. Conclusions A split-dose regime of TPF prior to surgery is feasible, tolerated and merits additional investigation in a phase II study with a dose of 30 mg/m docetaxel per week.

    Primary systemic treatment of breast cancer with cytotoxics yields a high response rate and allows conservative surgical procedures in bulky tumours. In order to maximise local control of disease, two innovations were introduced in a pilot study. The first was to identify the good responders after three cycles of chemotherapy and to treat them with three additional cycles. The second was to also give this group of patients a full dose of radiotherapy before surgery with the aim of verifying the rate of pathological complete remissions in view of a possible treatment of breast primary with chemoradiotherapy only. Patients were treated with doxorubicin 60 mg/m{sup 2} and cyclophosphamide, 600 mg/m{sup 2} both intravenously on day 1, every 21 days for three courses. Partial or complete responders received three more courses followed by radiotherapy (50 Gy plus a 10 Gy boost). The others underwent immediate surgery. A total of 32 patients (median age, 50 years; range 28-69 years); performance status, 0-1; T{sub 2} 22, T{sub 3} 8, T{sub 4} 2) were enrolled and were evaluable for response and side-effects. 9 patients had only three cycles of chemotherapy due to absence of response and 23 patients had six cycles of chemotherapy. Overall, 7 patients had a complete remission, 16 a partial remission and 9 had stable disease, for an overall response rate of 72% (95% confidence interval 53-86%). In the group of patients that completed the programme, two complete pathological remissions were observed and 5 patients had only microfoci of tumour. No toxic death or grade III-IV toxicities were observed. Mild or moderate side-effects included mucositis, nausea/vomiting and leucopenia. In conclusion, our results indicate that the addition of radiotherapy to pre-operative chemotherapy did not significantly enhance the incidence of pathological complete remissions. New primary treatment approaches should be explored in this subset of patients in order to improve outcome. (Copyright (c

    To evaluate the usefulness chemotherapy for postoperative adjuvant therapy, authors compared with chemoradiotherapy and the prognosis was analyzed. Patients were 171 cases of endometrial carcinoma which underwent surgery between January 1976 and December 1993. They were accurately determined the surgical stages. In chemoradiotherapy group, patients received irradiation on whole-pelvis or para-aortic lymph nodes after chemotherapy. In the IIIc stage patients, who received combined therapy with chemotherapy (CP or CAP regimen) and radiotherapy, the prognosis was significantly better than those by the chemotherapy alone. The five-year survival rate was 90.9% in chemoradiotherapy group and 50.0% in chemotherapy alone group. The trial on the regimen of chemotherapy and the use of new anti-cancer drugs will be required.

    Abstract This study explored which kinds of cancer are related to a higher incidence of subsequent myelodysplastic syndrome (MDS) after radiotherapy (RT) and chemotherapy (CT). We performed a nested case–control study by using data from the Taiwanese National Health Insurance (NHI) system. The case group included cancer patients who developed MDS. For the control group, 4 cancer patients without MDS were frequency-matched with each MDS case by age, sex, year of cancer diagnosis, and MDS index year. A multivariable logistic regression analysis was conducted, and odds ratios (ORs) and 95% confidence intervals (CIs) were estimated. Overall, cancer patients who received RT or CT exhibited secondary MDS more frequently than did those who did not (RT: OR = 1.53; 95% CI = 1.33–1.77; CT: OR = 1.51; 95% CI = 1.25–1.82). Analysis by cancer site showed that RT increased the risk of MDS for patients with stomach, colorectal, liver, breast, endometrial, prostate, and kidney cancers. By contrast, CT was more likely to increase the risk of MDS for patients with lung, endometrial, and cervical cancers. Further analysis revealed that RT and CT seemed to have a positive interaction. The major limitation of this study was the lack of certain essential data in the NHI Research Database, such as data regarding cancer stage and treatment dose details. This population-based nested case–control study determined that RT and CT predisposed patients in Taiwan to the development of MDS. This effect was more prominent when both modalities were used.

    Postoperative combined modality therapy with radiotherapy and 5-fluorouracil (5FU) chemotherapy is an effective adjuvant approach that reduces locoregional and distant metastatic disease in patients with high-risk rectal carcinoma. However, this approach results in a treatment regimen of at least 6 months` duration. The present prospective study investigates the integration of radiotherapy and 5FU chemotherapy in a protocol designed to minimize toxicity and reduce the overall treatment time. A total of 40 patients with TNM stage 11 or 111 disease receives postoperative radiotherapy at four fractions per week with weekly 5FU bolus injections delivered on the fifth non radiotherapy day. Patients also received systemic chemotherapy with leucovorin both before and after pelvic irradiation, with the total treatment duration extending for only 18 weeks. Patients were able to complete radiotherapy in 90% of cases, while the delivery of full-dose chemotherapy was achievable in the vast majority. The incidence of haematologic and gastrointestinal toxicities requiring the cessation of treatment was acceptable. With a median follow-up of 20.9 months among surviving patients, the estimated progression-free and overall survival at 2 years were 71% and 79%, respectively.

    Full Text Available Myoepithelial carcinoma (malignant myoepithelioma of the breast is a rare tumor, for which only a limited number of reports have been published. Most of the reports emphasized diagnosis and pathology but not biological behavior and treatment. We report a 61-year-old patient with breast myoepithelial carcinoma who developed locoregional and distant metastases and received many chemotherapy regimens. She presented with an elastic hard mass of the left breast. Breast conserving surgery was performed as part of both diagnosis and treatment. From the results of histological and immunohistochemical examinations, this case was considered to be a myoepithelial carcinoma. Fifteen months after the completion of adjuvant radiotherapy, distant metastasis of the left parasternal lymph node metastasis developed. She was treated by further excision and received a total of four regimens of chemotherapy including a combination of doxorubicin and cyclophosphamide. She received chemotherapy for 20 months after the diagnosis of metastasis.

    In 1996, a multicenter randomized study comparing after breast-conservative surgery. sequential vs concurrent adjuvant chemotherapy (CT) with radiation therapy (RT) was initiated (ARCOSEIN study). Seven hundred sixteen patients were included in this trial. After a median follow-up of 6.7 (4.3 -9) years, we decided to prospectively evaluate the late effects of these two strategies. Patients and methods - A total of 297 patients were asked to follow-up from the five larger including institutions. Seventy-two percent (214 patients) were eligible for late toxicity. After breast-conserving surgery with axillary dissection, patients were treated either with sequential treatment with CT first followed by RT (arm A) or CT administered concurrently with RT (arm B). In all patients, CT regimen combined mitoxantrone (12 mg/m{sup 2}). 5-FU (500 mg/m{sup 2}), and cyclophosphamide (500 mg/m{sup 2}), 6 cycles (day 1-day 21). In arm B, patients received concurrently the first 3 cycles of CT with RT. In arm A, RT started 3 to 5 weeks after the 6. cycle of CT. Conventional RT was delivered to the whole breast using a 2 Gy-fraction protocol to a total dose of 50 Gy ({+-} boost to the primary tumour bed). The assessment of toxicity was blinded to treatment and was graded by the radiation oncologist according to the LENT-SOMA scale. Skin pigmentation was also evaluated using a personal 5-points scoring system (excellent, good, moderate, poor, very poor). Results - Among the 214 evaluated patients, 107 were treated in each arm. The two populations were homogeneous for patients', tumors' and treatment characteristics. Subcutaneous fibrosis (SF), telangiectasia (T), skin pigmentation (SP), and breast atrophy (BA) were significantly increased in arm B. Twenty patients experienced grade superior or equal to 2 (SF) in arm B vs five in arm A (P 0.003). Twenty-five and seven patients showed grade superior or equal to 2 (T) in ann B and A, respectively (P = 0.001). Forty-four and

    To present patterns of practice and outcomes in the adjuvant treatment of intermediate- and high-risk endometrial cancer. Retrospective data on 224 women with intermediate-risk and high-risk endometrial cancer from 1999 to 2006 were reviewed. All patients underwent surgical staging. Patterns of adjuvant treatment, consisting of pelvic radiotherapy, chemotherapy, and radiotherapy plus chemotherapy, were assessed. The 3- and 5-year disease-specific survival (DSS) rates were calculated using the Kaplan-Meier method. The difference in 5-year DSS rate was statistically significant between adjuvant group and non-adjuvant group (80.65% vs. 63.80%, P=0.040). In 110 high-risk patients who underwent adjuvant treatment, both 5-year DSS rate and recurrent rate were significantly different in combined radiotherapy and chemotherapy group compared with radiotherapy alone and chemotherapy alone groups (DSS rate, P=0.049; recurrent rate, P=0.047). In 83 intermediate-risk women who underwent adjuvant treatment, there was no significant difference in 5-year DSS rate and recurrence rate among the combined radiotherapy and chemotherapy, radiotherapy alone and chemotherapy alone groups (DSS rate, P=0.776; recurrent rate, P=0.937). Adjuvant radiotherapy plus chemotherapy is associated with a higher 5-year DSS rate and lower recurrence rate compared with radiotherapy alone and chemotherapy alone in high-risk endometrial cancer patients. Patients with intermediate-risk endometrial cancer may be not likely to benefit from adjuvant combined radiotherapy and chemotherapy.

    Systemic chemotherapy has been performed for brain metastasis in small cell lung cancer based on the idea that the blood-brain-barrier may not function in the tumor tissue. In order to elucidate the role of radiotherapy and chemotherapy in this situation, a retrospective study was performed. Response rates to radiotherapy and chemotherapy were 55% and 31%, respectively. The median survival times (MST) of radiotherapy alone, chemotherapy alone and combined therapy were 1.6, 4.0 and 6.1 months, respectively, and there were significant differences between radiotherapy alone and combined therapy and between chemotherapy alone and combined therapy. Forty-nine percent of patients who were treated with radiotherapy alone, 63% with chemotherapy alone and 42% with combined therapy died of brain metastasis. The MST of the patients with no prior therapy, relapsed patients whose response to the initial chemotherapy was CR and relapsed patients whose response were PR, were 6.1, 6.1 and 3.3 months, respectively. In the former 2 groups, the presence of brain metastasis is not considered to be a contraindication for chemotherapy. However, chemotherapy should be combined with radiotherapy since relative poor survival and high frequency of death due to tumor were observed when treated with chemotherapy alone, and radiotherapy is considered to be useful as a palliative treatment because of its high response rate and low toxicity.

    Full Text Available Abstract Background To analyze the rate of larynx preservation in patients of locally advanced hypopharyngeal cancer treated with intensity modulated radiotherapy (IMRT plus concurrent chemotherapy, and compare the results with patients treated with primary surgery. Methods Between January 2003 and November 2007, 14 patients were treated with primary surgery and 33 patients were treated with concurrent chemoradiotherapy (CCRT using IMRT technique. Survival rate, larynx preservation rate were calculated with the Kaplan-Meier method. Multivariate analysis was conducted for significant prognostic factors with Cox-regression method. Results The median follow-up was 19.4 months for all patients, and 25.8 months for those alive. The 5-year overall survival rate was 33% and 44% for primary surgery and definitive CCRT, respectively (p = 0.788. The 5-year functional larynx-preservation survival after IMRT was 40%. Acute toxicities were common, but usually tolerable. The rates of treatment-related mucositis (≥ grade 2 and pharyngitis (≥ grade 3 were higher in the CCRT group. For multivariate analysis, treatment response and cricoid cartilage invasion strongly correlated with survival. Conclusions IMRT plus concurrent chemotherapy may preserve the larynx without compromising survival. Further studies on new effective therapeutic agents are essential.

    A 60-year-old female, who complained of delayed healing and swelling after extraction of left lower second molar during chemotherapy, visited our department. She had a history of a resection surgery of breast cancer and postoperative radiotherapy. The conventional radiographs showed diffuse primitive bone destruction in posterior mandibular body, which gave the first radiologic impression of osteonecrosis associated with radiotherapy or chemotherapy. And bone metastasis from the breast cancer was also considered in the differential diagnosis. On the enhanced computed tomography (ECT) the posterior mandibular body was occupied by a large expansible lesion showing central low attenuation with peripheral rim enhancement. Magnetic resonance images revealed that the low attenuated area on ECT did not show as high signal intensity as water on T2 weighted image and indicated solid component of a tumor. The final diagnosis was central squamous cell carcinoma. We present the diagnostic imaging features of the patient with special emphasis on the differential diagnosis.

    Science.gov (United States)

    Barazzuol, Lara

    Glioblastoma (GBM) is the most common primary brain tumour in adults and among the most aggressive of all tumours. For several decades, the standard care of GBM was surgical resection followed by radiotherapy alone. In 2005, a landmark phase III clinical trial coordinated by the European Organization for Research and Treatment of Cancer (EORTC) and the National Cancer Institute of Canada (NCIC) demonstrated the benefit of radiotherapy with concomitant and adjuvant temozolomide (TMZ) chemotherapy. With TMZ, the median life expectancy in optimally managed patients is still only 12-14 months, with only 25% surviving 24 months. There is an urgent need for new therapies in particular in those patients whose tumour has an unmethylated methylguanine methyltransferase gene (MGMT) promoter, which is a predictive factor of benefit from TMZ. In this dissertation, the nature of the interaction between TMZ and radiation is investigated using both a mathematical model, based on in vivo population statistics of survival, and in vitro experimentation on a panel of human GBM cell lines. The results show that TMZ has an additive effect in vitro and that the population-based model may be insufficient in predicting TMZ response. The combination of TMZ with particle therapy is also investigated. Very little preclinical data exists on the effects of charged particles on GBM cell lines as well as on the concomitant application of chemotherapy. In this study, human GBM cells are exposed to 3 MeV protons and 6 MeV alpha particles in concomitance with TMZ. The results suggest that the radiation quality does not affect the nature of the interaction between TMZ and radiation, showing reproducible additive cytotoxicity. Since TMZ and radiation cause DNA damage in cancer cells, there has been increased attention to the use of poly(ADP-ribose) polymerase (PARP) inhibitors. PARP is a family of enzymes that play a key role in the repair of DNA breaks. In this study, a novel PARP inhibitor, ABT-888

    Background: Locoregional treatment of inflammatory breast cancer (IBC) is crucial because local relapses may be highly symptomatic and are commonly associated with distant metastasis. With a median follow-up of 20 years, we report here the long-term results of a monocentric clinical trial combining primary chemotherapy (CT) with a schedule of anthracycline-based CT and an alternating split-course of radiotherapy (RT Asterisk-Operator CT) without mastectomy. Methods and Materials: From September 1983 to December 1989, 124 women with nonmetastatic IBC (T4d M0) were treated with three cycles of primary AVCMF chemotherapy (anthracycline, vincristine, cyclophosphamide, methotrexate, and 5-fluorouracil) and then an alternating RT Asterisk-Operator CT schedule followed by three cycles of FAC. Hormonal therapy was systematically administered: ovarian irradiation (12 Gy in four fractions) or tamoxifen 20 mg daily. Results: Local control was achieved in 82% of patients. The 10- and 20-year local relapse rates were 26% and 33%, respectively, but only 10% of locally controlled cases were not associated with concurrent distant metastasis. The 10- and 20-year overall survival rates were 39% and 19%, respectively. Severe fibrosis occurred in 54% of patients, grade 3 brachial plexus neuropathy in 4%, grade 2 pneumonitis in 9%. Grade 1, 2 and 3 cardiac toxicity was observed in 3.8%, 3.8% and 1.2% of cases respectively. Conclusions: This combined regimen allowed good long-term local control without surgery. Survival rates were similar to those obtained with conventional regimens (primary chemotherapy, total mastectomy, and adjuvant radiotherapy). Since IBC continues to be an entity with a dismal prognosis, this approach, safely combining preoperative or postoperative radiation therapy and systemic treatments, should be reassessed when suitable targeted agents are available.

    Nasopharyngeal angio-fibroma is a locally aggressive, although histologically benign, vascular neoplasm. This neoplasm accounts for 0.05% of head and neck tumours and affects almost exclusively male adolescents. Surgery is considered as the primary treatment of nasopharyngeal angio-fibroma. Other treatment modalities such as radiotherapy and chemotherapy are still recommended for intracranial extension involving the cavernous sinus or the internal carotid artery. We report a rare case of nasopharyngeal angio-fibroma, further complicated with a Kennedy syndrome in a 34 year-old women. The treatment consisted in a chemotherapy (adriamycin, decarbazine) followed by radiotherapy. We discuss the relevance and outcome of the association chemotherapy-radiotherapy in the treatment of nasopharyngeal angio-fibroma with a consistent intracranial extension (stage III B of Arch Otolaryngol Head Neck Surg 122 (2003) 122-129).

    Full Text Available Neoadjuvant chemotherapy (NAC is widely used in locally advanced breast cancer (BC treatment. The role of postmastectomy radiotherapy (PMRT after NAC is strongly debated. The aim of our analysis was to identify major prognostic factors in a single-center series, with emphasis on PMRT. From 1997 to 2011, 170 patients were treated with NAC and mastectomy at our center; 98 cases (57.6% underwent PMRT and 72 cases (42.4% did not receive radiation. At a median follow-up period of 7.7 years (range 2–16 for the whole cohort, median time to locoregional recurrence (LRR was 3.3 years (range 0.7–12.4. The 5-year and 10-year actuarial LRR rate were 14.5% and 15.9%, respectively. At the multivariate analysis the factors that significantly correlated with survival outcome were ≥4 positive nodes (HR 5.0, 1.51–16.52; P=0.035, extracapsular extension (HR 2.18, 1.37–3.46; P=0.009, and estrogen receptor positive disease (HR 0.57, 0.36–0.90; P=0.003. Concerning LRR according to use of radiation, PMRT reduced LRR for patient with clinical T3 staged disease (P=0.015. Our experience confirmed the impact of pathological nodal involvement on survival outcome. PMRT was found to improve local control in patients presenting with clinical T3 tumors, regardless of the response to chemotherapy.

    Full Text Available Acquired lymphangiectasia (AL is a significant and rare complication of surgery and radiotherapy. We report lymphangiectasia in a 40-year-old woman who had undergone radical mastectomy and radiotherapy. After 4 years of combined therapy, she developed multiple vesicles and bullae. Skin biopsy confirmed the diagnosis of lymphangiectasia. The case is unique as it is not associated with lymphedema, which is a usual accompaniment of lymphangiectasia following surgery and radiotherapy. AL is usually asymptomatic, but trauma may cause recurrent cellulitis. Treatment modalities include electrodessication, surgical excision, sclerotherapy and carbon dioxide laser ablation.

    To compare "sandwich chemo-radiotherapy" with six cycles of chemotherapy followed by adjuvant radiotherapy with respect to tolerability and acute toxicity. Twenty-five women with surgically staged IIIC endometrial cancer were included. Treatment consisted of either three cycles of paclitaxel (175 mg/m²) and carboplatin (AUC 6) on a q21-day schedule followed by irradiation (45-50.4 Gy) or six cycles of the same chemotherapy followed by radiotherapy. Acute toxicity related to either chemotherapy or radiotherapy was evaluated. Median age was 61.5 years (range 36-83 years). Eleven patients had sandwich chemo-radiotherapy, and the other 14 patients had 6 cycles of chemotherapy followed by radiotherapy. Three out of the five patients who could not complete all the cycles in the sandwich chemo-radiotherapy group had pelvic and para-aortic radiotherapy. Acute radiotherapy related grade 1-2 gastrointestinal system (GIS) and genitourinary system (GUS) toxicities were observed in 72.8 and 63.6 % of patients, respectively, for sandwich group. Undesired treatment breaks in the course of radiotherapy were observed in six patients for sandwich chemo-radiotherapy and in one patient receiving six cycles of chemotherapy followed by radiotherapy. All the patients who had undesired treatment breaks in the sandwich chemo-radiotherapy group had pelvic and para-aortic radiotherapy. Sandwich chemo-radiotherapy seems to be more toxic particularly for patients who had pelvic and para-aortic irradiation. Therefore, it might be more convenient to delay radiotherapy after six cycles of chemotherapy for patients with the indication of pelvic para-aortic radiotherapy.

    To evaluate the role of salvage radiotherapy (RT) for the treatment of regional lymph node recurrence (RLNR) after radical surgery in advanced gastric cancer. We retrospectively analyzed medical records of 26 patients who underwent salvage treatment after diagnosis of RLNR between 2006 and 2011. Patients with peritoneal seeding or distant metastasis were excluded. Eighteen patients received RT with or without chemotherapy and the other 8 did chemotherapy only without RT. A three-dimensional conformal RT was performed with median dose of 56 Gy (range, 44 to 60 Gy). Sixteen patients had fluoropyrimidine-based chemotherapy, 5 did taxane-based chemotherapy, and irinotecan was applied in 4. With a median follow-up of 20 months (range, 5 to 57 months), median overall survival (OS) and progression-free survival (PFS) after diagnosis of RLNR were 29 months and 12 months in the entire patients, respectively. Radiotherapy (p = 0.007) and disease-free interval (p = 0.033) were statistically significant factors for OS in multivariate analysis. Median OS was 36 months in patients who received RT and 16 months in those who did not. Furthermore, delivery of RT (p < 0.001), complete remission after salvage treatment (p = 0.040) and performance status (p 0.023) were associated with a significantly better PFS. Gastrointestinal toxicities from RT were mild in most patients. Salvage RT combined with systemic chemotherapy may be an effective treatment managing RLNR from advanced gastric cancer.

    Eleven cases of inoperable non-small cell lung cancer were treated with hyperfractionated radiotherapy combined with chemotherapy. Hyperfractionated radiotherapy consisted of 1.6 Gy per fraction, 2 fractions a day with 6 hours between fractions, 5 days a week for a total of 60.8 Gy. After 38.4 Gy of irradiation to the primary tumor, hilar, and mediastinal lymph nodes, an additional 22.4 Gy was given to primary lesion. Chemotherapy consisted of cisplatin, 80 mg/m{sup 2} day 1, mitomycin C, 10 mg/m{sup 2} day 1, and vinblastine, 5 mg/m{sup 2}, days 1 and 15. At least 2 courses were administered. The combination of radiotherapy and chemotherapy was sequential. Of 6 patients in whom hyperfractionated radiotherapy was performed first, 5 achieved partial response (PR). Of 5 patients in whom chemotherapy was performed first, 2 achieved PR. Median survival time was 300 days. Nine of the eleven patients experienced esophagitis, but in all patients this was controlled easily by oral antacids and/or H{sub 2} blockers. In regard to radiation pneumonitis, fibrosis occurred in seven of nine cases, but they did not require corticosteroids. Levels of hematological toxicity were similar to previous reports, but were somewhat severe in cases receiving chemotherapy after irradiation. We conclude that hyperfractionated radiotherapy combined with chemotherapy including cisplatin is safe, but further evaluation to determine optimal dose and combination methods is necessary.

    To evaluate the toxicity and efficacy of adjuvant chemotherapy after radiotherapy for patients with locally advanced head and neck squamous cancer, 40 patients, previously untreated (6 with stage III and 34 with stage IV; 26 with resectable, 10 with unresectable and 4 patients with inoperable) were treated with radiotherapy followed by adjuvant chemotherapy (Nedaplatin /tegafur-uracil (UFT)) at our outpatient clinic. The primary site was identified in the larynx or hypopharynx in 15, oral cavity or oropharynx in 11, sinuses in 6, nasopharynx in 4, unknown primary in 3, and parotis in 1 patient. Treatment consisted of 6 courses of Nedaplatin 80 mg/m{sup 2} repeated at 4 weeks intervals, and one-year oral administration of UFTE 400mg/day, after radiotherapy. Toxicities included leukopenia (grade 3, 20.5%, grade 4, 2.6%), thrombocytopenia (grade 3, 7.7%). There was one death due to gastric ulcer. Twenty-five patients (62.5%) received 6 courses of adjuvant chemotherapy. Two-year overall survival rate was 100% for stage III and 61.1% for stage IV. Over the same period, the progression-free survival rate was 83.3% for stage III and 46.1% for stage IV. 85.7% of complete response (CR) (12/14 patients) and 63.6% of partial response (PR) (14/22 patients) to radiotherapy showed that the effect of radiotherapy was maintained during adjuvant chemotherapy. If the effect of radiotherapy was maintained during adjuvant chemotherapy, the two-year progression free survival rate was not different between 81.8% for CR to radiotherapy and 81.3% for PR. The rate of distant failure was 2.5%, which was lower than that citedin previous reports. This adjuvant chemotherapy regimen is tolerable at outpatient clinics and might suppress distant metastasis after radiotherapy. (author)

    The sequential use of chemotherapy and surgery in the treatment of osteosarcoma developed in an empirical fashion without the benefit of investigations in animal models. The MGH-OGS murine osteosarcoma is a transplantable tumor that resembles the human disease with respect to histology, local invasiveness, metastatic characteristics, tumor ploidy, and its response to chemotherapy. We have used this tumor model to investigate the efficacy of preoperative, perioperative, and postoperative chemotherapy on the development of pulmonary metastases in three different experimental protocols. In each experimental design, perioperative chemotherapy demonstrated a significant advantage in preventing systemic relapse.

    To determine the impact of a policy change in which women with high-risk early stage endometrioid endometrial cancer (EEC) received adjuvant chemoradiotherapy. This is a population-based retrospective cohort study of British Columbia Cancer Registry patients diagnosed from 2008 to 2012 with high-risk early stage EEC, who received adjuvant chemoradiotherapy after primary surgery. High-risk early stage was defined as the presence of two or more high-risk uterine factors: grade 3 tumor, more than 50% myometrial invasion, and/or cervical stromal involvement. Adjuvant therapy consisted of 3 or 4 cycles of carboplatin and paclitaxel chemotherapy, followed by pelvic radiotherapy. Sites and rate of recurrence were compared to a historical cohort diagnosed from 2005 to 2008 in which none of the patients received adjuvant chemoradiotherapy. Five-year progression-free and overall survival rates were calculated. The study includes 55 patients. All patients except for 2 received at least 3 cycles of chemotherapy. All patients received pelvic radiotherapy except for 2 who received brachytherapy only. Median follow-up was 27 months (7-56 months). Four patients (7.3%) recurred, including three with distant recurrence only and one with both a pelvic and paraaortic nodal recurrence. The historical cohort had a 29.4% recurrence rate, and therefore the hazard ratio for recurrence was 0.27 (95% CI 0.02-4.11). Five-year progression-free and overall survival rates were 88.6% and 97.3%, respectively. Patients with high-risk early stage endometrial carcinoma treated with adjuvant chemoradiotherapy have a low rate of recurrence compared to those not receiving such therapy. © 2013.

    For the last four decades, the treatment of cancer has relied on four treatment modalities, namely surgery, radiotherapy, cytotoxic chemotherapy, and hormonotherapy. Most of these therapies are believed to directly attack and eradicate tumor cells. The emerging concept that cancer is not just a disease of a tissue or an organ but also a host disease relies on evidence of tumor-induced immunosuppression and polymorphisms in genes involved in host protection against tumors. This theory is now gaining new impetus, based on our recent data showing that optimal therapeutic effects require the immunoadjuvant effect of tumor cell death induced by cytotoxic anticancer agents. Here, we show that the release of the high mobility group box 1 protein (HMGB1) by dying tumor cells is mandatory to license host dendritic cells (DCs) to process and present tumor antigens. HMGB1 interacts with Toll-like receptor 4 (TLR4) on DCs, which are selectively involved in the cross-priming of anti-tumor T lymphocytes in vivo. A TLR4 polymorphism that affects the binding of HMGB1 to TLR4 predicts early relapse after anthracycline-based chemotherapy in breast cancer patients. This knowledge may be clinically exploited to predict the immunogenicity and hence the efficacy of chemotherapeutic regimens.

    Full Text Available Purpose: Treatment of advanced Non small cell lung cancer (NSCLC often produces dismal results. Combination of available treatment modalities has reportedly improved the outcome. A prospectively randomized trial was conducted, comparing combined treatment modalities versus radiotherapy alone, in treatment of unresectable NSCLC. Materials and Methods: A total of 103 patients were randomized to three groups. In group ′A′, 32 patients received radiotherapy alone (6500 cGy/30 fraction. In group ′B′, 35 patients received neoadjuvant chemotherapy (Cisplatin 80 mg/m2 on day 1 and Etoposide 100 mg/m day 1-3 intravenously q3 weeks for 3 cycles, followed by radiotherapy (6000 cGy/30 fractions and 3 more cycles of Chemotherapy, with the same regimen. In group ′C′, 36 patients received radiotherapy (5000 cGy/25 fractions with concurrent chemotherapy (ciplatin 20 mg/m2 + Etoposide 75 mg/m2 intravenously on day 1-5 and day 22-26, followed by 2 more cycles of chemotherapy,q3 weeks with the same regimen. Results: Initial treatment responses were significantly higher in group ′B′ ( P P Conclusion: Addition of chemotherapy with radiation in unresectable NSCLC improves response rates, time to tumour progression and disease free survival, though the same effect is not translated in overall survival.

    Full Text Available Purpose. Conservative treatment in the form of limited surgery and post-operative radiotherapy is controversial in hand and foot sarcomas, both due to poor radiation tolerance of the palm and sole, and due to technical difficulties in achieving adequate margins.This paper describes the local control and survival of 41 patients with soft tissue sarcoma of the hand or foot treated with conservative surgery and radiotherapy. The acute and late toxicity of megavoltage radiotherapy to the hand and foot are described. The technical issues and details of treatment delivery are discussed. The factors influencing local control after radiotherapy are analysed.

    Neoadjuvant chemotherapy (NAC), the systematic chemotherapy given to patients with locally advanced and inoperable breast caner, has been proven to be of great clinical values. Many scientific reports confirmed NAC could effectively eliminate sub-clinical disseminated lesions of tumor, and improve long-term and disease-free survival rate of patients with locally advanced breast cancer (LABC); however, up to now, LABC is still a serious clinical issue given improved screening and early diagnosis. This study, with main focus on inoperable LABC, investigated the values of NAC in converting inoperable LABC into operable status and assessed the prognosis. Sixty-one patients with inoperable LABC were initially treated with neoadjuvant chemotherapy; their local conditions were improved to operable status. Radical surgery was exerted on 49 patients. Original chemotherapy was performed after surgery, followed by local radiotherapy. And endocrine therapy was optional according to the hormone receptor status. The quality of life for most patients with skin diabrosis was obviously improved because their local conditions were under control. For all recruited cases, the survival duration and life quality were significantly improved in patients who finished both NAC and surgery compared to those who did not. Further more, this study demonstrates improved prognostic consequences.

    Full Text Available The purpose of this study was to find a more efficacious treatment for patients with primary central nervous system Lymphoma using chemotherapy. The objective was to determine the optimal time for radiotherapy treatment in relation to chemotherapy. Retrospective evaluation in patients with brain lymphoma was conducted from 1992 to 1998. Twenty-three patients were evaluated. Patients were divided into two groups based on the timing of radiotherapy in relation to the chemotherapy. The first group of patients (n=13 initially received radiotherapy followed by chemotherapy. Five of these patients receied classic CHOP (cyclophosphamide, Doxorubicine, Vincistine and Prednisone, six patients received Cis-platin (60 Megs/M2 and Etoposide (120 Megs/M2 and two patients received Cis-platin (60 Megs/M2, Etoposide (120 Megs/M2 and Cytarabine (600 Megs/M2 every 2 to 3 weeks. The second group of patients (Group II, n=10 received the followeing treatment regimen: a course of BCNU 120 Megs/M2 with Ifosfamide 1200 Megs/M2, Mesna and Etoposide 120 Megs/M2 on the first day of treatment (course A. Two weeks later, treatment was continued with a course of Cis-platin 35 Megs/M2 and Cytarabine 600 Megs/M2 (course B.

After the fourth week of chemotherapy, these patients received radiotherapy to the brain (5000 RADS in 4 weeks. During radiotherapy and at the beginning of course chemotherapy, intrathecal therapy with Methorexate 12 Megs/M2 and Cytarabine 60 Megs/M2 was given. Immediately after radiotherapy, the same chemothotrexate 12 Megs/M2 and Cytarabine 60 Megs/M2 was given. Immediately after radiotherapy, the same chemotherapy treatment was repeated to a total of 3 times. After complete clearance of the tumor determined by MRI and absence of tumor cells in the spinal fluid, the chemotherapeutic regimen was repeated one last time. The

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

    Primary mediastinal seminoma is an uncommon neoplasm, the optimal management of which is still debated. Radiotherapy produces a 65% disease-free survival rate. We assess whether these results have been improved with the advent of cisplatin-based chemotherapy. Data from 14 patients treated at the Institut Gustave-Roussy were reviewed. 9 had received cisplatin-based chemotherapy (Group 1): their outcome was compared with that of 5 patients treated with radiotherapy without chemotherapy (Group 2). We also reviewed data from the English literature using strict criteria, and report results concerning patients who received cisplatin-based chemotherapy and those who received radiotherapy. 8 of the 9 patients (89%) in Group 1 are long-term disease-free survivors and only 3 of 5 patients in Group 2. The patient who died in Group 1 was the only one who refused surgical resection of residual masses after chemotherapy. The review of the literature revealed that 59 of 68 (87%) patients initially managed with cisplatin- or carboplatin-based chemotherapy and for whom sufficient data are available, are long-term survivors and free of disease. Some of these patients had also received radiotherapy. Only 64 of 103 (62%) treated with thoracic radiotherapy without chemotherapy were long-term disease-free survivors. The disease-free survival rate of 51 patients who received cisplatin-based chemotherapy (excluding those who received carboplatin) was 86%. The difference in survival between patients administered cisplatin-based chemotherapy and those who underwent radiotherapy is apparently not due to unbalanced prognostic factors, the effect of time or non-specific medical management. We conclude that cisplatin-based chemotherapy allows long-term disease-free survival in approximately 85% of patients. These results seem to be higher than those obtained without cisplatin-based chemotherapy. However, a randomised study is required for definitive conclusions, but it is very unlikely that

    To assess the relationship between the timing of radiotherapy and the risk of local failure in patients with endometrioid-type endometrial cancer who had undergone surgery and adjuvant external pelvic radiotherapy (with or without brachytherapy), but not chemotherapy. One hundred and seventy seven patients were analyzed in this study. The median follow-up of the survivors was 72 months. Radiotherapy was delivered after a median time of 14.6 weeks from surgery and the median overall treatment time was 6.4 weeks. The tumor relapsed in 32 (18.1%) patients after a median time of 21 months. The local recurrence (vaginal or central pelvic) occurred in 11 patients. The local recurrence rate was associated with tumor grade (p=0.02), myometrial invasion (p=0.046), FIGO stage (p=0.003), pathological node status (p=0.037) and time interval from surgery to radiotherapy using 9 weeks as the cut-off value (p=0.046), but not with the overall treatment time. All the local relapses occurred in patients who received adjuvant irradiation after an interval from surgery >9 weeks. The time interval from surgery to radiotherapy might affect the local recurrence rate in patients not receiving chemotherapy. Every possible effort should be made to start radiotherapy within 9 weeks, when radiotherapy only is deemed necessary as adjuvant treatment.

    To determine the impact of clinical variables and adjuvant therapy on survival in patients with Stage IVB endometrial cancer (EC) confined to abdomen. A total of 65 patients were included. Curative chemotherapy was defined as using only chemotherapy (platin based) or sandwich therapy. Patients receiving only radiotherapy had standard pelvic radiotherapy and extended-field radiotherapy when necessary. The optimal cytoreduction was achieved in 89.3% of patients. With a median follow-up of 18 months, two-year progression free survival (PFS) and overall survival (OS) were calculated as 33.4% and 42.2%, respectively. Optimal cytoreduction provided more longer PFS and OS compared to suboptimal cytoreduction. In univariate analysis, curative chemotherapy instead of radiotherapy improved the two-year PFS and two-year OS. Type of adjuvant therapy, tumor grade, and peritoneal cytology were found as the independent prognostic factors for PFS. Peritoneal cytology, adnexal involvement, and adjuvant therapy were independent prognostic factor for OS. Curative chemotherapy significantly improved both two-year PFS and OS in patients with Stage IVB endometrial disease confined to abdomen over only radiotherapy.

    Successful therapeutic interventions to prevent disease progression in patients with nonmetastatic osteosarcoma have included surgery with adjuvant chemotherapy. Presurgical chemotherapy has been advocated for these patients because of putative improvement in event-free survival (EFS). The advantages of presurgical chemotherapy include early administration of systemic chemotherapy, shrinkage of primary tumor, and pathologic identification of risk groups. The theoretic disadvantage is that it exposes a large tumor burden to marginally effective chemotherapy. The contribution of chemotherapy and surgery timing has not been tested rigorously. Between 1986 and 1993, we conducted a prospective trial in patients with nonmetastatic osteosarcoma who were assigned randomly to immediate surgery or presurgical chemotherapy. Except for the timing of surgery (week 0 or 10), patients received 44 weeks of identical combination chemotherapy that included high-dose methotrexate with leucovorin rescue, doxorubicin, cisplatin, bleomycin, cyclophosphamide, and dactinomycin. One hundred six patients were enrolled onto this study. Six were excluded from analysis. Of the remaining 100 patients, 45 were randomly assigned to immediate chemotherapy, and 55 were randomly assigned to immediate surgery. Sixty-seven patients remain disease-free. At 5 years, the projected EFS +/- SE is 65% +/- 6% (69% +/- 8% for immediate surgery and 61% +/- 8% for presurgical chemotherapy; P =.8). The treatment arms had similar incidence of limb salvage (55% for immediate surgery and 50% for presurgical chemotherapy). Chemotherapy was effective in both treatment groups. There was no advantage in EFS for patients given presurgical chemotherapy.

    Background: To evaluate the efficacy of multimodality therapy in patients with esthesioneuroblastoma (ENB). Patients and Methods: From 01/1979 through 08/2001, 47 patients with ENB (20 men, 27 women, age 5-81 years), were registered from 18 oncologic centers. There were 14 tumors stage B and 33 stage C according to the Kadish classification. Initial treatment included surgery alone in seven patients, radiotherapy (RT) with or without chemotherapy (CTX) in twelve, surgery plus postoperative RT in 15, and multimodality therapy (surgery plus pre- or postoperative CTX plus postoperative RT) in 13. Results: The 5-year overall survival (OS) for the whole group was 64 {+-} 8% and the 5-year event-free survival (EFS) 50 {+-} 8%. Patients with multimodality treatment had a significantly better 5-year EFS (74 {+-} 13%) compared to the other patients (41 {+-} 9%; p = 0.05), while the 5-year OS was not significantly different between the treatment groups (p = 0.39). For patients with Kadish stage C, multimodality therapy (n = 11) resulted in superior 5-year EFS (72 {+-} 14% vs 17 {+-} 9%; p = 0.01). These patients tended to have an improved OS (69 {+-} 15% vs 47 {+-} 12%; p = 0.19) compared to the other treatment groups. None of the patients with multimodality treatment had a metastatic relapse. Conclusion: Multimodality treatment (surgery plus pre- or postoperative CTX plus postoperative RT) appears to be highly efficient in preventing local and systemic relapse in patients with advanced ENB. Timing and optimal agents of CTX need to be further evaluated. (orig.)

    We intended to decrease late CNS reaction after radical radiotherapy for an intracranial germinoma by using combined neoadjuvant chemotherapy and involved-field radiotherapy. The efficacy in terms of its acute toxicity and short-term relapse patterns was analyzed. Eighteen patients were treated with combined neoadjuvant chemotherapy and radiotherapy between 1995 and 2001. The chemotherapy regimen used was the Children's Cancer Group (CCG) 9921A (cisplatin, cyclophosphamide, VP-16, vincristine) for 5 patients younger than 16 years, BEP(bleomycin, VP-16, cisplatin) for 12 patients, and EP (VP-16, cisplatin) for 1 patient. The radiotherapy covered the whole craniospinal axis for 5 patients, the whole brain for 1, and the partial brain (involved field) for 12. the primary lesion received tumour doses between 3,960 and 5,400 cGy. The male to female ratio was 16:2 and the median age was 16 years old. The tumors were located in the pineal gland in 12 patients, in the suprasellar region in 1, in the basal ganglia in 1, in the thalamus in 1. Three patients had multiple lesions and ventricular seedings were shown at MRI. In 3 patients, tumor cells were detected in the cerebrospinal fluid and MRI detected a spinal seeding in 2 patients. The response to neoadjuvant chemotherapy was complete remission in 5 patients, partial remission in 12, and no response in 1. However, after radiotherapy, all except 1 patient experienced complete remission. The toxicity during or after chemotherapy greater than or equal to grade III was remarkable; hematologic toxicity was observed in 11 patients, liver toxicity in none, kidney toxicity in none, and gastrointestinal toxicity in one. One patient suffered from bleomycin-induced pneumonitis. Radiotherapy was therefore stopped and the patient eventually died of respiratory failure. The other 17 are alive without any evidence of disease or relapse during an average of 20 months follow-up. A high response rate and disease control was

    Indications for radiotherapy and chemotherapy in stage II seminoma are currently debated. Since 1980, the policy at Institut Gustave Roussy was to treat patients with stage IIA-B disease with external radiotherapy and patients with stage IIB-C with cisplatin-based chemotherapy. In stage IIB disease, 3 cm was the usual tumor size threshold above which individual patients were considered for chemotherapy. During the period 1980-2001, 67 patients with stage II seminoma were treated: stage IIA (n = 5), stage IIB (n = 31), and stage IIC (n = 31). The median age was 40 years (range: 23-64). Among 37 patients who received radiotherapy, 5, 28, and 4 had a stage IIA, IIB, and IIC, respectively. Among 30 patients who received chemotherapy, 27 had a stage IIC. With a median follow-up of 9.4 years, 19 relapses (28%) occurred, including 11 and 8 cases treated with radiotherapy (30%) and chemotherapy (27%), respectively. The 5-year relapse-free survival was 71% (95% CI: 59-80). All but three relapses were salvaged with chemotherapy followed in selected cases by surgical resection of residual masses. Only 3 patients died of seminoma. The 5-year overall survival rate is 97% (95% CI: 89-99). Five patients subsequently developed a non-germ-cell second cancer, which occurred within the radiation field in 3 cases. With an overall survival rate of 97%, the overall outcome of patients with stage II seminoma managed according to this risk-adapted strategy is good. The possibility of extending the indications for chemotherapy to selected stage IIB seminoma patients needs to be further evaluated as potentially beneficial in terms of relapse risk.

Seven patients received breast-conserving treatment and 4 patients received modified radical operation. All the patients received postoperative radiotherapy and 8 patients received chemotherapy. Results Of the 11 patients, molybdenum target examination found 9 positive patients and B ultrasound found 6 positive patients. Because the diagnosis was late, the numbers of patients with stageⅠ, stageⅡ and stage Ⅲ tumor were 2, 5 and 4. Follow-up of all the patients found that 9 patients survived and were free of the disease and 2 patients had local relapse or metastasis 2 years after the treatment.ConclusionMisdiagnosis of pregnancy breast cancer is commonly seen, so the role of mammary examination and ultrasound examination during the pregnancy and lactation periods should be emphasized in the diagnosis. In the treatment, the urgency of disease and the safety of fetuses should be considered at the same time. The study shows that on the premise of allowing the comprehensive treatment combining chemotherapy and radiotherapy, breast-conserving treatment is a feasible way to treat pregnancy breast cancer.%目的:对妊娠期乳腺癌的诊断、手术、放疗、化疗等综合治疗方面的特殊性进行探讨。方法回顾性分析自2000年5月~2007年5月期间某院收治的妊娠期乳腺癌患者11例,其中属于妊娠期的有5例,分娩后1年内的有6例。对7例患者实施了乳房保留治疗,4例实施改良根治术,且所有患者在术后进行放疗,有8例接受了化疗。结果11例患者通过钼靶检查中有9例以及6例B超

    Purpose. - To determine whether exclusive radiotherapy could be a therapeutic option after complete clinical response (cCR) to neo-adjuvant chemotherapy (NCT) for early breast cancers (EBC). Patients and methods. - Between 1985 and 1999, 1477 patients received neo-adjuvant chemotherapy for early breast cancer considered to be too large for primary conservative surgery. Of 165 patients with complete clinical response, 65 were treated by breast surgery (with radiotherapy) and 100 by exclusive radiotherapy. Results. - The two groups were comparable in terms of baseline characteristics, except for larger initial tumor sizes in the exclusive radiotherapy group. There were no significant differences in overall, disease-free and metastasis-free survivals. Five-year and 10-year overall survivals were 91 and 77% in the no surgery group and 82 and 79% in the surgery group, respectively (P = 0.9). However, a non-significant trend towards higher locoregional recurrence rates (LRR) was observed in the no surgery group (31 vs. 17% at 10 years; P = 0.06). In patients with complete responses on mammography and/or ultrasound, LRR were not significantly different (P = 0.45, 10-year LRR: 21 in surgery vs. 26% in exclusive radiotherapy). No significant differences were observed in terms of the rate of cutaneous, cardiac or pulmonary toxicities. Conclusion. - Surgery is a key component of locoregional treatment for breast cancers that achieved complete clinical response to neo-adjuvant chemotherapy. (authors)

    This paper characterizes regulatory procedures applied by private health plan operators on their outpatient radiotherapy and chemotherapy services, especially via contracts, and outlines the health care providers’ perception on regulation. The study relied on primary data, taking into consideration 638 hospitals and outpatient health care units with the services in question. A stratified random sample was selected, resulting in the inclusion of 54 units that are representative of the population, excluding hospitals that only provide radiotherapy. Private chemotherapy services are largely funded by health insurance plans (75.0%), while radiotherapy services are predominantly covered by the public health system (49.0%). Contracts are not applied by third part payers, in their potential, as regulatory and health care coordination instruments. The mechanisms of regulation applied by third part payers are centered on services use control and administrative aspects. It is recognized the need of adjustments for a health care quality focus, and contracts may contribute in this sense.

    The concurrent use of radiotherapy (RT) and chemotherapy (CT) as adjuvant treatment after surgery in high-risk endometrial cancer has been generally considered cautiously. Recently some of us have reported preliminary data on the efficacy and tolerability of concomitant CT and RT. In this paper, we update our experience. A total of 47 patients aged >18 years and endometrial endometrioid carcinomas entered the study. Inclusion criteria were stages IC G3, IIB, IIIA (patients with positive washing without other unfavourable prognostic factors were omitted), IIIB and IIIC. The radiation plan consisted of a total dose of 50.4 Gy, given in five fractions per week (1.8 Gy: daily dose) for 6 weeks. Paclitaxel (P) at a dose of 60 mg/m(2) was infused intravenously in 250 mL of normal saline for 1 h once weekly during RT for 5 weeks. Three further cycles of Paclitaxel, at a dose of 80 mg/m(2), have been given weekly at the end of RT. There was no life-threatening toxicity. The overall 5-year relapse-free survival was 81.8% (95% CI, 65.2-90.9). The 5-year percent overall disease-specific survival was 88.4% (95% CI, 71.1-95.6). These results, based on a larger series, support our previous data: Paclitaxel plus RT may represent an effective and well-tolerated treatment in high-risk endometrial cancer patients.

    Purpose: Despite a previously published randomized trial, controversy exists regarding the benefit of adding surgery to radiotherapy for metastatic spinal cord compression (MSCC). It is thought that patients with MSCC from relatively radioresistant tumors or tumors associated with poor functional outcome after radiotherapy alone may benefit from surgery. This study focuses on these tumors. Methods and Materials: Data from 67 patients receiving surgery plus radiotherapy (S+RT) were matched to 134 patients (1:2) receiving radiotherapy alone (RT). Groups were matched for 10 factors and compared for motor function, ambulatory status, local control, and survival. Additional separate matched-pair analyses were performed for patients receiving direct decompressive surgery plus stabilization of involved vertebrae (DDSS) and patients receiving laminectomy (LE). Results: Improvement of motor function occurred in 22% of patients after S+RT and 16% after RT (p = 0.25). Posttreatment ambulatory rates were 67% and 61%, respectively (p = 0.68). Of nonambulatory patients, 29% and 19% (p = 0.53) regained ambulatory status. One-year local control rates were 85% and 89% (p = 0.87). One-year survival rates were 38% and 24% (p = 0.20). The matched-pair analysis of patients receiving LE showed no significant differences between both therapies. In the matched-pair analysis of patients receiving DDSS, improvement of motor function occurred more often after DDSS+RT than RT (28% vs. 19%, p = 0.024). Posttreatment ambulatory rates were 86% and 67% (p = 0.30); 45% and 18% of patients regained ambulatory status (p = 0.29). Conclusions: Patients with MSCC from an unfavorable primary tumor appeared to benefit from DDSS but not LE when added to radiotherapy in terms of improved functional outcome.

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

    The case history is reported of a patient with a carcinoma of the duodenum 30 years after blunt abdominal trauma at the site of the 'scar' in the duodenum. Thirteen years after the trauma the patient was treated with chemotherapy and abdominal irradiation for a relapse of Hodgkin's disease. At follow-up, 25 months after the operation, he had no local recurrence of Hodgkin's disease or duodenal cancer. The possible relation between the cancer and the abdominal trauma, chemotherapy and abdominal irradiation is discussed.

    AIM: To evaluate the effect of chemotherapy to the acute toxicity of a hypofractionated radiotherapy (HFRT) schedule for breast cancer. METHODS: We retrospectively analyzed 116 breast cancer patients with T1, 2N0Mx. The patients received 3-D conformal radiotherapy with a total physical dose of 50.54 Gy or 53.2 Gy in 19 or 20 fractions according to stage, over 23-24 d. The last three to four fractions were delivered as a sequential tumor boost. All patients were monitored for acute skin toxicity according to the European Organization for Research and Treatment of Cancer/Radiation Therapy Oncology Group criteria. The maximum monitored value was taken as the final grading score. Multivariate analysis was performed for the contribution of age, chemotherapy and 19 vs 20 fractions to the radiation acute skin toxicity. RESULTS: The acute radiation induced skin toxicity was as following: grade I 27.6%, grade II 7.8% and grade III 2.6%. No significant correlation was noted between toxicity grading and chemotherapy (P = 0.154, χ2 test). The mean values of acute toxicity score in terms of chemotherapy or not, were 0.64 and 0.46 respectively (P = 0.109, Mann Whitney test). No significant correlation was also noted between acute skin toxicity and radiotherapy fractions (P = 0.47, χ2 test). According to univariate analysis, only chemotherapy contributed significantly to the development of acute skin toxicity but with a critical value of P = 0.05. However, in multivariate analysis, chemotherapy lost its statistical significance. None of the patients during the 2-years of follow-up presented any locoregional relapse. CONCLUSION: There is no clear evidence that chemotherapy has an impact to acute skin toxicity after an HFRT schedule. A randomized trial is needed for definite conclusions. PMID:25405195

    To investigate the clinical features and therapeutic effects of sudden deafness after radiotherapy combined with chemotherapy in nasopharyngeal carcinoma patients. Clinical data of 42 nasopharyngeal carcinoma patients suffered from sudden deafness after radiotherapy combined with chemotherapy were analyzed retrospectively. Among the 42 patients, 2 showed moderate deafness, 4 presented excessive deafness, 30 suffered from severe deafness, and 6 exhibited profound deafness. The audiogram pattern of 33 patients met with the type of high tone frequencies hearing loss, and that of the rest 9 cases showed hearing loss at all frequencies. All patients received medical therapy combined with hyperbaric oxygen therapy. Of all the cases with hearing loss, 2 were cured, 2 showed excellent recovery, 9 came out partial recovery, and 29 showed no response to the treatment. The total effective rate was 30.95%. For the accompanied symptoms, none of the 30 cases of tinnitus were relieved, 3 out of 10 cases of aural fullness were cured, and the 5 cases of dizziness or vertigo were all improved. The sudden deafness after radiotherapy combined with chemotherapy in patients with nasopharyngeal carcinoma is closely related to radiotherapy. The hearing loss is serious, and the therapeutic effects are not satisfactory.

    Experience obtained in a group of 44 patients with advanced cervical cancer is reported. In this study, patients with residual cancer underwent laparotomy eight weeks after one or two different radiotherapy protocols. Sixty-eight percent of patients underwent radical surgery, 85% of patients pelvic exenterations, and 15% radical hysterectomies. In 27% of patients, no evidence of residual cancer was found in surgical specimens. Radical surgery was well tolerated, and one-third of patients were free of disease for one year or more. Control of disease was obtained in 50% of pelvic extenterations and in 60% of radical hysterectomies, regardless of prognosis, clinical stage or radiotherapy scheme. Although results show an improvement of up to 22% when comparing this to other more conventional treatments, it has been concluded that a wider experience in order to support the findings must be obtained.

    The objective of our study was to determine whether adjuvant chemotherapy combined with postoperative radiotherapy would have benefits for the disease-free survival and overall survival in patients with high-risk endometrial cancer. Electronic searches for studies of adjuvant chemotherapy combined with postoperative radiotherapy in endometrial cancer patients between March 1971 and March 2012 were made on MEDLINE, SCOPUS, and the Cochrane library. Articles with more than 4 stars on the Newcastle-Ottawa scale or a score of more than 4 on the modified Jadad scale were included. A meta-analysis was performed, and pooled hazard ratios (HR) of progression-free survival (PFS) and overall survival (OS) between patients whose adjuvant chemotherapy was combined with radiotherapy (the CTx+RTx group) and patients with adjuvant radiotherapy only (the RTx group) were derived from the fixed effect model or random effect model. Three observational studies and 3 randomized clinical trials (RCTs) were included in the final analysis. Subgroup analysis for FIGO stage showed that the CTx+RTx group had a more significant survival benefit compared to that of the RTx group in advanced stage endometrial cancer (OS HR 0.53, 95% CI 0.36-0.80; PFS HR 0.54, 95% CI 0.37-0.77), but no significant benefit in early stage endometrial cancer (OS HR 0.96, 95% CI 0.70-1.32; PFS HR 1.00, 95% CI 0.39-2.58). This meta-analysis suggests that adjuvant chemotherapy combined with postoperative radiotherapy could probably reduce disease progression and overall death in patients with advanced-stage disease. In order to examine whether the multimodal treatment has benefit in high-risk endometrial cancer, we need further large-scale RCTs. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

    Introduction Endometrial cancer patients with high grade tumours, deep myometrial invasion, or advanced stage disease have a poor prognosis. Randomized studies have demonstrated prevention of loco-regional relapses with radiotherapy with no effect on overall survival. The possible additive effect of chemotherapy remains unclear. Two randomized clinical trials (NSGO-EC-9501/EORTC-55991 and MaNGO ILIADE-III) were undertaken to clarify if sequential combination of chemotherapy and radiotherapy improves progression-free survival in high-risk endometrial cancer. The two studies were pooled. Methods Patients (n=540; 534 evaluable) with operated endometrial cancer FIGO stage I-III with no residual tumour and prognostic factors implying high-risk were randomly allocated to adjuvant radiotherapy with or without sequential chemotherapy. Results In the NSGO/EORTC study, combined modality treatment was associated with a 36 % reduction in the risk for relapse or death (HR 0.64, 95 % CI 0.41-0.99; P=0.04); two-sided tests were used. The result from the MaNGO-study pointed in the same direction (HR 0.61), but was not significant. In combined analysis, the estimate of risk for relapse or death was similar but with narrower confidence limits (HR 0.63, CI 0.44-0.89; P=0.009). Neither study showed significant differences in overall survival. In combined analysis, overall survival approached statistical significance (HR 0.69, CI 0.46-1.03; P = 0.07) and cancer-specific survival was significant (HR 0.55, CI 0.35-0.88; p=0.01). Conclusion Addition of adjuvant chemotherapy to radiation improves progression-free survival in operated endometrial cancer patients with no residual tumour and high risk profile. A remaining question for future studies is if addition of radiotherapy to chemotherapy improves the results. PMID:20619634

    Oral mucositis is a common side effect of systemic chemotherapy and radiotherapy of head and neck in patients with cancer. Severe oral mucositis is painful and affects oral functions, including intake of food and medications and speech. Prevention of oral mucositis affects the life quality of patients. Recent studies have been focused on natural products to improve or reduce this complication. Many clinical trials have been performed to assess natural products for treatment of mucositis and their results are promising. The authors reviewed the evidence for natural products in the prevention and treatment of oral mucositis induced by radiation therapy and chemotherapy.

    Peritoneal surface malignancies are generally associated with poor prognosis.In daily clinical routine,systemic chemotherapy is still considered the only reasonable therapy despite of encouraging results of cytoreductive surgery (CRS) along with intraperitoneal hyperthermic chemotherapy (HIPEC).The Achilles heel of CRS and HIPEC is appropriate patient selection and precise surgical technique preventing patients from excessive morbidity and mortality.Given these findings,new concepts of second look surgery for high risk patients allow detection of peritoneal spread ahead of clinical symptoms or presence of peritoneal masses reducing perioperative morbidity.In addition,personalized intraperitoneal chemotherapy might further improve outcome by appreciating individual tumor biology.These days,every physician should be aware of CRS and HIPEC for treatment of peritoneal surface malignancies.Since there is now sufficient data for the superiority of CRS and HIPEC to systemic chemotherapy in selected patients,our next goal should be providing this strategy with minimal morbidity and mortality even in the presence of higher tumor load.

    SUMMARY Purpose This study was aimed at assessing the effectiveness and the importance of an oral hygiene (OH) protocol in patients undergoing radiation therapy and chemotherapy after prosthesis rehabilitation, in order to reduce or minimize oral complications. Materials and methods This study was carried out at the Department of Dental Science, at the University of Bari-Italy from December 2012 to December 2015 on 34 selected patients with primary oral cancer undergoing chemotherapy and radiotherapy after prosthesis rehabilitation. They were divided into 2 groups according to their age, sex and cancer therapy. Seventeen patients were assigned to the control group and seventeen in the experimental one. In the experimental group (Table 1), patients underwent an oral hygiene protocol whereas in the control group (Table 2) patients received the usual care provided within the clinical setting. All the patients gave written informed consent. It has been asked and obtained the authorisation from the Ethics Committee of the Dental Science and Surgery Department. Results Results show that in patients undergoing the oral hygiene protocol, the complications and the risks of infection and permanent dental problems have been minimized. Indeed, of the seventeen patients undergoing the OH protocol, 70% obtained positive results and were satisfied with the program outcome. Conclusions The role of the health care providers is essential to educate patients to adhere to the prescribed treatments and reinforce their motivation in oral hygiene. The oral hygiene procedures prevent and ameliorate oral complications due to the radiation therapy and chemotherapy. PMID:28280537

    The adjuvant treatment of gastric cancer includes radiotherapy and chemotherapy. The patient underwent gastrectomy on November 10, 2006 and began adjuvant chemotherapy (McDonald scheme) on january 2, 2007, finishing on june 1, 2007. Radiotherapy was started on February 6, 2007 and finished on March 16, 2007. The care plan presented was designed following the Virginia Henderson model and is routinely used at the Reina Sofía Hospital. This care plan follows the NANDA, NOC and NIC taxonomies and is based on the following nursing diagnoses: risk of infection, fear, and disposition to improve knowledge. During the clinical course, two new nursing diagnoses were identified: deterioration of oral mucosa and skin integrity.

    Cytoreductive surgery and Hyperthermic Intraperitoneal Chemotherapy have achieved good long-term results in patients with complete surgical eradication of their peritoneal dissemination but at the expense of significant perioperative morbidity and mortality. The high complication rate has been attributed to the steep learning curve associated with this procedure. We report on the current literature regarding the learning curve for this procedure and the key components that determine the success in learning this new skill.

    concurrently with radiotherapy. Weekly administration of these drugs at reduced doses during a full course of conformational radiotherapy up to 70 Gy or more, however, resulted in encouraging results in several phase II studies, with median survival in excess of 20 months and 2- and 3-year survival rates near 50% and 40%, respectively. The respective benefits of either induction or consolidation full-dose chemotherapy with these drugs, before or after concurrent chemoradiotherapy with second- or third-generation chemotherapy, are presently being evaluated in phase III studies. As a result of improved survival and enhanced local control, most of these studies show a significant increase in the incidence of brain metastases. Because the brain is often the first site of relapse after concurrent chemoradiotherapy with or without surgery, the issue of prophylactic cranial irradiation is currently being addressed in a phase III trial.

  20. Efficacy of Rasayana Avaleha as adjuvant to radiotherapy and chemotherapy in reducing adverse effects

    OpenAIRE

    2010-01-01

    Cancer is the most dreadful disease affecting mankind. The available treatments such as chemotherapy and radiotherapy have cytotoxic effects, which are hazardous to the normal cells of the patient, causing many unnecessary effects. This further leads to complications of the therapy, impaired health, and deterioration of quality of life, resulting in mandatory stoppage of the treatment. In the present study, the efficacy of an Ayurvedic formulation, Rasayana Avaleha, has been evaluated as an a...

    Full Text Available It has been found that preoperative plasma IGFBP-2 levels correlate with prognosis in glioma patients. The prognostic value of plasma IGFBP-2 after postoperative combined radiotherapy and chemotherapy in glioma patients is unknown. Plasma IGFBP-2 levels in 83 glioblastoma patients after postoperative radiotherapy plus chemotherapy were analyzed using an IGFBP-2 ELISA kit. We found that after standard therapy plasma IGFBP-2 levels significantly correlated with the patient's age (R = 0.738, P<0.001 and Karnofsky performance status (KPS, R =  -0.633, P<0.05. Cox proportional hazards models were used to calculate hazard ratios (HRs of death according to plasma IGFBP-2 levels adjusted for patient clinical characteristics. Plasma IGFBP-2 levels significantly correlated with overall survival in glioblastoma patients (multivariate HR = 1.035; 95% CI, 1.024-1.047; P<0.001. The effect of plasma IGFBP-2 levels on survival seemed to differ according to patients' age. Among patients older than 60, high plasma IGFBP-2 levels were associated with a significant increase in overall mortality (HR = 1.097; 95% CI, 1.055-1.140; P<0.001. In contrast, plasma IGFBP-2 levels conferred no significant effect on mortality among patients younger than 60. Elevated plasma IGFBP-2 levels after combined postoperative radiotherapy and chemotherapy in elderly glioblastoma patients correlate with poor KPS score and predicts poor prognosis.

    Conventional cancer treatments rely on radiotherapy and chemotherapy. Such treatments supposedly mediate their effects via the direct elimination of tumor cells. Here we show that the success of some protocols for anticancer therapy depends on innate and adaptive antitumor immune responses. We describe in both mice and humans a previously unrecognized pathway for the activation of tumor antigen-specific T-cell immunity that involves secretion of the high-mobility-group box 1 (HMGB1) alarmin protein by dying tumor cells and the action of HMGB1 on Toll-like receptor 4 (TLR4) expressed by dendritic cells (DCs). During chemotherapy or radiotherapy, DCs require signaling through TLR4 and its adaptor MyD88 for efficient processing and cross-presentation of antigen from dying tumor cells. Patients with breast cancer who carry a TLR4 loss-of-function allele relapse more quickly after radiotherapy and chemotherapy than those carrying the normal TLR4 allele. These results delineate a clinically relevant immunoadjuvant pathway triggered by tumor cell death.

    We analyzed the treatment outcomes and prognostic factors of breast conserving surgery, followed by postoperative radiotherapy. Materials and Methods: A total of 424 breast cancer patients treated with breast conserving surgery and postoperative radiotherapy between February 1992 and January 2001 were retrospectively analyzed. A quadrantectomy and axillary lymph node dissection was performed in 396 patients. A total of 302 patients had T1 disease, and 122 patients had T2 disease. Lymph node involvement was confirmed in 107 patients. Whole breast irradiation was administered at up to 50.4 Gy in 28 fractions, followed by a 10 Gy boost in 5 fractions to the tumor bed. In addition, 57 patients underwent regional lymph node irradiation. Moreover, chemotherapy was administered in 231 patients. A regimen consisting of cyclophosphamide, methotrexate, and 5-fluorouracil was most frequently used with 170 patients. The median follow-up time was 64 months. Results: The 5-year local control rate was 95.6%. During the follow-up period, local tumor recurrence was observed in 15 patients. The 5-year overall and disease-free survival rates were 93.1% and 88.7%, respectively. The 5-year overall survival rates, by stage, were 94.8% for stage I, 95.0% for stage IIA, 91.1% for stage IIB, 75.9% for stage IIIA, and 57.1% for stage IIIC. As for disease-free survival, the corresponding figures, by stage (in the same order), were 93.1%, 89.4%, 82.8%, 62.0%, and 28.6%, respectively. The advanced N stage (p=0.0483) was found to be a significant prognostic factor in predicting poor overall survival, while the N stage (p=0.0284) and age at diagnosis (p=0.0001) were associated with disease-free survival. Conclusion: This study has shown that breast conserving surgery and postoperative radiotherapy for early breast cancer results was excellent for local control and survival.

    Background Despite broad advances in multimodal treatment of locally advanced breast cancer (LABC), 30 to 40% of patients develop loco-regional relapse. The aim of this study was to analyze in a retrospective manner the effectiveness of concurrent chemo-radiotherapy (CCRTh) after neoadjuvant chemotherapy (NCT) in patients with LABC. Methods One hundred twelve patients with LABC (stage IIB-IIIB) were treated with NCT (5-fluorouracil 500 mg/m2, doxorubicin 50 mg/m2, and cyclophosphamide 500 mg/m2 (FAC), or doxorubicin 50 mg/m2 and cyclophosphamide 500 mg/m2 (AC) IV in four 21-day courses) followed by CCRTh (60 Gy breast irradiation and weekly mitomycin 5 mg/m2, 5-fluorouracil 500 mg/m2, and dexamethasone 16 mg, or cisplatin 30 mg/m2, gemcitabine 100 mg/m2 and dexamethasone 16 mg), and 6–8 weeks later, surgery and two additional courses of FAC, AC, or paclitaxel 90 mg/m2 weekly for 12 weeks, and in case of estrogen-receptor positive patients, hormonal therapy. Results Stages IIB, IIIA and -B were 21.4, 42.9, and 35.7%, respectively. Pathological complete response (pCR) in the breast was 42% (95% CI, 33.2–50.5%) and, 29.5% (95% CI, 21.4–37.5%) if including both the breast and the axillary nodes. Multivariate analysis showed that the main determinant of pCR was negative estrogen-receptor status (HR = 3.8; 95% CI, 1.5–9; p = 0.016). The 5-year disease-free survival (DFS) was 76.9% (95% CI, 68.2–84.7%). No relationship between pCR and DFS was found. Multivariate analysis demonstrated that the main DFS determinant was clinical stage (IIB and IIIA vs. IIIB, HR = 3.1; 95% CI, 1.02–9.74; p = 0.04). Only one patient had local recurrence. Five-year overall survival was 84.2% (95% CI, 75–93.2%). The toxicity profile was acceptable. Conclusion This non-conventional multimodal treatment has good loco-regional control for LABC. Randomized clinical trials of preoperative CCRTh following chemotherapy, in patients with LABC are warranted. PMID:19591689

    Purpose: To analyze the recent single-institution experience of patients with salivary gland tumors who had undergone adjuvant intensity-modulated radiotherapy (IMRT), with or without concurrent chemotherapy. Patients and Methods: We performed a retrospective analysis of 35 salivary gland carcinoma patients treated primarily at the Dana-Farber Cancer Institute between 2005 and 2010 with surgery and adjuvant IMRT. The primary endpoints were local control, progression-free survival, and overall survival. The secondary endpoints were acute and chronic toxicity. The median follow-up was 2.3 years (interquartile range, 1.2-2.8) among the surviving patients. Results: The histologic types included adenoid cystic carcinoma in 15 (43%), mucoepidermoid carcinoma in 6 (17%), adenocarcinoma in 3 (9%), acinic cell carcinoma in 3 (9%), and other in 8 (23%). The primary sites were the parotid gland in 17 (49%), submandibular glands in 6 (17%), tongue in 4 (11%), palate in 4 (11%), and other in 4 (11%). The median radiation dose was 66 Gy, and 22 patients (63%) received CRT. The most common chemotherapy regimen was carboplatin and paclitaxel (n = 14, 64%). A trend was seen for patients undergoing CRT to have more adverse prognostic factors, including Stage T3-T4 disease (CRT, n = 12, 55% vs. n = 4, 31%, p = .29), nodal positivity (CRT, n = 8, 36% vs. n = 1, 8%, p = .10), and positive margins (n = 13, 59% vs. n = 5, 38%, p = .30). One patient who had undergone CRT developed an in-field recurrence, resulting in an overall actuarial 3-year local control rate of 92%. Five patients (14%) developed distant metastases (1 who had undergone IMRT only and 4 who had undergone CRT). Acute Grade 3 mucositis, esophagitis, and dermatitis occurred in 8%, 8%, and 8% (1 each) of IMRT patients and in 18%, 5%, and 14% (4, 1, and 3 patients) of the CRT group, respectively. No acute Grade 4 toxicity occurred. The most common late toxicity was Grade 1 xerostomia (n = 8, 23%). Conclusions: Treatment of

    A case of dento-maxillofacial abnormality involving a 10-year-old male patient with a history of esthesioneuroblastoma is presented. This patient had been treated with 54 Gy {sup 60}Co-gamma-radiation to the nasal cavity for 6 weeks and 6 cycles of combination chemotherapy of Cyclophosphamide, Cisplatin, Adriamycin, VM-26 (Teniposide), and DTIC (Dacarbazine) when he was 16 months of age. Five years after cessation of cancer therapy, he was disease free and transferred for extensive dental care to Kyung Hee University Dental Hospital. A clinical and radiologic follow-up over last 4 years showed root stunting, premature closure of the root apices, microdontia, developmental arrest, small crowns, and partial anodontia. Maxillofacial morphology evaluated by cephalometric analysis showed deficiency of maxillary development.

    Forty-five patients with muscle-invasive bladder cancer treated with intra-arterial doxorubicin chemotherapy plus low-dose radiotherapy between September 1979 and March 1990 were retrospectively studied. Twenty-eight (62%) patients achieved a complete response (CR) and in all of them, a functional bladder could be preserved. The 10-year cause-specific survival rate of patients with CR was 95.5%, but that of patients not achieving a CR was 39%. These results demonstrate that in patients who achieve a CR with this treatment, we may be able to preserve a functional bladder. In a prospective study, we designed a new intra-arterial chemotherapy regimen in order to achieve a higher degree of effectiveness and to preserve a functional bladder. Twenty-three patients were treated with concurrent pirarubicin/cisplatin intra-arterial chemotherapy and radiotherapy after complete transurethral resection. Twenty-one (91%) patients achieved CR. One of these patients had relapse with lung metastases and was treated surgically. Two patients who did not achieve a CR died of cancer, and 21 patients are alive with preservation of functional bladder. For treatment of prostate cancer, we now administer only adjuvant intra-arterial chemotherapy plus irradiation for patients after radical prostatectomy. (author)

    Twenty-nine patients with locally advanced head and neck cancer were treated with twice-a-day fractionated radiotherapy (TDFR) for a total dose of 72 Gy to 82 Gy combined with Neo-adjuvant chemotherapy (NAC) of CDDP+5FU and concurrent chemotherapy of low dose CBDCA between 1994 and 1997. Twenty-one cases (72%) had complete response and sixteen cases recurred. The relapse-free rate at 2 years was 23.4% and the actual 2-year survival rate was 42.0%. No severe toxicity has been observed. Based on this investigation, it was concluded that TDFR with chemotherapy is a promising modality for locally advanced head and neck cancer and toxicity is acceptable. (author)

    Between January 1983 and December 1988, 218 female patients with known breast cancer and positive axillary nodes were treated with adjuvant radiotherapy and chemotherapy following radical mastectomy. Treatment results were retrospectively analysed at the Department of Radiation Oncology, Yonsei Cancer Center, Yonsei University of College of Medicine. The patients were classified into 3 groups; group 1 included 80 patients treated with adjuvant chemotherapy alone; in group 2, 52 patients treated with radiotherapy alone; and in group 3, 86 patients treated with combined chemo-radiotherapy. The mean age was 44 years and ranged from 27 to 70. The median follow-up time was 51 months. Seven-year relapse free and overall survival rates were 56% and 67%; in group 1, 50% and 56%; in group 2, 51% and 65%; and in group 3, 62% and 75% respectively. This difference was not statistically significant(p<0.05). The loco-regional failure rates were 13% and distant failure rates were 33%. There was less risk of loco-regional failure in group 2 and 3 which included radiotherapy (.0<0.05). But there was no significant y difference in the rates of distant failure(p>0.05). By univariate analysis, the only significant prognostic factor affecting relapse-free survival was the percentage of positive axillary nodes; and the overall survival significantly correlated with the primary tumor size, the number or percentage of positive axillary nodes, and stage. But in multivariate analysis, the only significant prognostic factor was treatment modality. By univariate analysis of prognostic factors affecting the rates of overall failure and distant failure, the significant prognostic factors was the percentage of positive axillary nodes; and the risk of the loco-regional failure significantly correlated with the treatment modality. In conclusion, these results suggest a potential for decreasing the risk of loco-regional failure with the addition of postoperative radiotherapy to chemotherapy in the

    This article aims to review the rationale behind the combination of radiotherapy and chemotherapy. Theoretical concepts describing the principles of the joint effects of chemoradiotherapy are reviewed. Preclinical and clinical evidence are collected and summarised demonstrating the co-operation between the two modalities which form the mainstay of the treatment of most solid tumours. Initially, the evolution of chemoradiotherapy was mostly empirically driven which is true for both, the early studies and the experimental investigations, rather than relying on scientific rationale. To date, the revised Steel's model proposes five mechanisms, spatial cooperation, cytotoxic enhancement, biological co-operation, temporary modulation and normal tissue protection to describe the interaction between radiotherapy and chemotherapy. Chemoradiotherapy has become the standard modality for most patients with locally advanced solid tumours due to better control of loco-regional disease and prolonged survival. Gradually, molecular prediction of efficacy is integrated such as MGMT status for combining temozolomide with radiotherapy in glioblastoma. As molecular targeted drugs are ready to be taken into triple combinations with chemoradiotherapy it is crucial to have a good understanding of the mechanisms of chemoradiotherapy for the rational development of future combinations.

  12. South Asian Medicinal Compounds as Modulators of Resistance to Chemotherapy and Radiotherapy

    Full Text Available Cancer is a hyperproliferative disorder that involves transformation, dysregulation of apoptosis, proliferation, invasion, angiogenesis and metastasis. During the last 30 years, extensive research has revealed much about the biology of cancer. Chemotherapy and radiotherapy are the mainstays of cancer treatment, particularly for patients who do not respond to surgical resection. However, cancer treatment with drugs or radiation is seriously limited by chemoresistance and radioresistance. Various approaches and strategies are employed to overcome resistance to chemotherapy and radiation treatment. Many plant-derived phytochemicals have been investigated for their chemo- and radio-sensitizing properties. The peoples of South Asian countries such as India, Pakistan, Sri Lanka, Nepal, Bangladesh and Bhutan have a large number of medicinal plants from which they produce various pharmacologically potent secondary metabolites. The medicinal properties of these compounds have been extensively investigated and many of them have been found to sensitize cancer cells to chemo- and radio-therapy. This review focuses on the role of South Asian medicinal compounds in chemo- and radio-sensitizing properties in drug- and radio-resistant cancer cells. Also discussed is the role of South Asian medicinal plants in protecting normal cells from radiation, which may be useful during radiotherapy of tumors to spare surrounding normal cells.

    Endometrial cancer patients with high grade tumours, deep myometrial invasion or advanced stage disease have a poor prognosis. Randomised studies have demonstrated the prevention of loco-regional relapses with radiotherapy (RT) with no effect on overall survival (OS). The possible additive effect of chemotherapy (CT) remains unclear. Two randomised clinical trials (NSGO-EC-9501/EORTC-55991 and MaNGO ILIADE-III) were undertaken to clarify if sequential combination of chemotherapy and radiotherapy improves progression-free survival (PFS) in high-risk endometrial cancer. The two studies were pooled. Patients (n=540; 534 evaluable) with operated endometrial cancer International Federation of Obstetrics and Gynaecology (FIGO) stage I-III with no residual tumour and prognostic factors implying high-risk were randomly allocated to adjuvant radiotherapy with or without sequential chemotherapy. In the NSGO/EORTC study, the combined modality treatment was associated with 36% reduction in the risk for relapse or death (hazard ratio (HR) 0.64, 95%confidence interval (CI) 0.41-0.99; P=0.04); two-sided tests were used. The result from the Gynaecologic Oncology group at the Mario Negri Institute (MaNGO)-study pointed in the same direction (HR 0.61), but was not significant. In the combined analysis, the estimate of risk for relapse or death was similar but with narrower confidence limits (HR 0.63, CI 0.44-0.89; P=0.009). Neither study showed significant differences in the overall survival. In the combined analysis, overall survival approached statistical significance (HR 0.69, CI 0.46-1.03; P=0.07) and cancer-specific survival (CSS) was significant (HR 0.55, CI 0.35-0.88; P=0.01). Addition of adjuvant chemotherapy to radiation improves progression-free survival in operated endometrial cancer patients with no residual tumour and a high-risk profile. A remaining question for future studies is if addition of radiotherapy to chemotherapy improves the results. Copyright 2010 Elsevier

    Recent literature on chemoradiotherapy for esophageal cancer report the comparable survival results as surgery, and suggest the importance of management for the late adverse effect of chemoradiotherapy. The aim of this study is to investigate the incidence and risk factors of cardiomegaly after chemoradiotherapy using low dose continuous infusion of 5FU/CDDP+5FU for esophageal cancer. Fifty-one patients with stage I-IVA esophageal cancer who were treated by radiotherapy with more than 50 Gy with or without chemotherapy and followed up for more than 6 months were analyzed. Sixteen patients were treated by radiation alone and 35 patients were treated by chemoradiotherapy. A change of CTR (cardio-thoracic ratio) was defined as the difference between CTR in the pre-treatment X-ray film and CTR in the post-treatment X-ray film with maximum cardiac silhouette. A change of CTR by more than 10% was defined as ''significant cardiomegaly''. In this study cardiac area-dose'', which is the sum of the products of cardiac area within every radiation field and its target dose, was calculated in each patient as a radiation parameter. Significant cardiomegaly was noted in 1 patient (6%) in the radiation alone group, in 8 patients (23%) in the chemoradiotherapy group and in 9 patients (18%) in the total population. In cases with more than 0.4 m{sup 2}{center_dot}Gy in cardiac area-dose, CTR elevation was significantly higher than in cases with less than 0.4m{sup 2}{center_dot}Gy. More than moderate pleural effusion was noted in 5 patients (10%). Chronic pericardial effusion and subsequent cardiac tamponade was considered to be one of the contributing factors for pleural effusion, because increases of pleural effusion coincided with CTR elevations in 3 cases. In addition, the fact that no case had right-sided unilateral pleural effusion suggested the direct effect of radiation to the pleura. Significant cardiomegaly was seen in 18% of 51 patients with

    Full Text Available Recent studies have shown that rebamipide, which suppresses reactive oxygen species, prevents chemoradiotherapy-induced oral mucositis in patients with head and neck cancers. However, anticancer action of radiotherapy and chemotherapy is believed to be partially associated with generation of reactive oxygen species. The aim of this study was to determine whether rebamipide interferes with the antitumor action of radiotherapy and chemotherapy. The effect of rebamipide on tumor cell growth was investigated using a human oral squamous carcinoma cell line, HSC-2, in vitro and in vivo. Rebamipide showed no significant effect on cell or tumor growth in HSC-2 tumor-bearing nude mice. Influences of rebamipide on the antitumor action of radiotherapy and of chemotherapy with cisplatin or docetaxel were investigated using the same animal model. In radiotherapy, the tumor was treated with 2.5 Gy of X-rays for 5 days, and rebamipide (300 mg/kg p.o. was administered during irradiation periods. In chemotherapy, tumor-bearing mice were treated once with cisplatin (8 mg/kg, i.v. or docetaxel (15 mg/kg i.v. and rebamipide (300 mg/kg p.o. was administered for 5 days following the antitumor drug treatment. Rebamipide did not interfere with the antitumor action of radiotherapy and chemotherapy.

In chemotherapy, tumor-bearing mice were treated once with cisplatin (8 mg/kg, i.v.) or docetaxel (15 mg/kg i.v.) and rebamipide (300 mg/kg p.o.) was administered for 5 days following the antitumor drug treatment. Rebamipide did not interfere with the antitumor action of radiotherapy and chemotherapy. Copyright © 2015 The Authors. Production and hosting by Elsevier B.V. All rights reserved.

    To analyze prognostic factors associated with long-term outcomes in patients with resected pancreatic cancer treated with chemotherapy (CT) and surgery with or without external beam radiotherapy (EBRT). From January 1995 to December 2012, 95 patients with adenocarcinoma of the pancreas and locoregional disease [clinical stage IB-IIA (n = 45; 47 %), IIB-IIIC (n = 50; 53 %)] were treated with curative resection [R0 (n = 52; 55 %), R1 (n = 43, 45 %)] and CT with (n = 60; 63 %) or without (n = 35; 37 %) EBRT (45-50.4 Gy). Additionally, 29 patients (48 %) also received a pre-anastomosis IOERT boost (applicator diameter size, 7-10 cm; dose, 10-15 Gy; beam energy, 9-18 MeV). With a median follow-up of 17.2 months (range, 1-182), 2-year overall survival (OS), disease-free survival (DFS), and locoregional control were 28, 20, and 53 %, respectively. Univariate analyses showed that IIB-IIIC stage (HR, 2.23; p = 0.04), R1 margin resection status (HR, 2.09; p = 0.04), no vascular resection (HR, 0.42; p = 0.02), and not receiving external beam radiotherapy (HR, 2.70; p = 0.004) were associated with locoregional recurrence. In the multivariate analysis, only R1 margin resection status (HR, 2.63; p = 0.009) and not receiving EBRT (HR, 2.91; p = 0.002) retained significance with regard to locoregional recurrence. We observed no difference in toxicity between patients treated with or without EBRT (p = 0.44). Overall treatment mortality was 3 %. No long-term treatment-related death occurred. Although adjuvant CT is still the standard of care for resected pancreatic tumors, OS remains modest owing to the high risk of distant metastases. Locoregional treatment needs to be tested in the context of more efficient systemic therapy. (orig.)

    Full Text Available Background: Carcinoma of uterine cervix is the commonest cancer affecting females in developing countries. Concurrent chemoradiation has remained the sole definitive treatment available in the advanced stages. The study was planned to take the advantage of radiosensitisation accruing due to chemotherapy at the time of brachytherapy, when approximately 40% of total tumor dose is applied. Subjects and Methods: Sixty-four patients were enrolled who had locally advanced uterine cervix carcinoma (Federation of Gynecology and Obstetrics Stage IIB–IVA from July 2011 to May 2013 for concurrent chemotherapy and intracavitory brachytherapy after completion of concurrent chemotherapy and external beam radiotherapy followed by three insertion of brachytherapy separated by a week by flexitron brachytherapy unit to Point A, for each application was 6 Gy by high dose rate. Cisplatin was given (35 mg/m2 1 day before brachytherapy in each application. Results: At medium follow-up of 19 months (range 8–30 months clinical complete response rate was found to be 89% at 3 months of follow-up. Acute side effect as nausea and vomiting Grades I and II were recorded as 55% and 28% respectively, no renal dysfunction and no thrombocytopenia were encountered. No patients had Grade IV or life threatening toxicity. Overall survival and disease free survival after 30 months of follow-up is 88% and 75% respectively. Conclusion: Use of concurrent chemotherapy with brachytherapy is effective and feasible with acceptable toxicity for locally advanced carcinoma of the uterine cervix.

    Protection of the patients against the side effects of chemotherapy and radiotherapy regimens has attracted increasing interest of clinicians and practitioners. Caffeic acid phenethyl ester (CAPE), which is extracted from the propolis of honeybee hives as an active component, specifically inhibits nuclear factor κB at micromolar concentrations and show ability to stop 5-lipoxygenase-catalysed oxygenation of linoleic acid and arachidonic acid. CAPE has antiinflammatory, antiproliferative, antioxidant, cytostatic, antiviral, antibacterial, antifungal and antineoplastic properties. The purpose of this review is to summarize in vivo and in vitro usage of CAPE to prevent the chemotherapy-induced and radiotherapy-induced damages and side effects in experimental animals and to develop a new approach for the potential usage of CAPE in clinical trial as a protective agent during chemotherapy and radiotherapy regimens.

    Objective: The aim of this study was to explore the three-dimensional conformal radiotherapy combined with FOLFOX scheme chemotherapy in the treatment of postoperative recurrence of rectal cancer. Methods: Sixty-eight cases of recurrent rectal cancer were divided randomly into two groups: 34 cases of conformal radiotherapy plus FOLFOX chemotherapy group (experiment group) and 34 cases of conformal radiotherapy (control group). After 6 MvX line with three-dimensional conformal radiotherapy technologies for recurrent lesions and pelvic cavity around subclinical lymphatic drainage radiotherapy after radiotherapy to DT 40 Gy to reposit was made use of between both groups, experiment group was made the new treatment plan to continue to irradiate to 50 Gy, and then Shrinkage GTV was pushed quantity in the field 66 Gy. Researchers took chemotherapy in the first week and the fourth week after radiotherapy, with 5-fluorouracil 500 mg/m2, calcium leucovorin 200 mg, d1-5 with intravenous drip, Oxaliplatin 130 mg/m2 and d1 with intravenous drip 2 h, 21 days was one cycle. Kaplan-Meier method was used for survival analysis. Results: The survival rates for 1, 2 and 3 years for experiment group and control group were 88.2%, 64.7%, 47.1% and 66.7%, 38.2%, 29.4% (P = 0.03), the 2-year rate of distant metastases was 32.4% and 58.8% (P = 0.032) respectively. The median survival time was 33 and 20 months respectively. There were some side effects between the groups, but there was no statistical difference. Conclusion: Three-dimensional conformal radiotherapy plus FOLFOX chemotherapy can be considered as a safe and effective approach to treat rectal cancer patients of postoperative recurrence, and can improve the survival rates of patients and reduce distant metastasis rate obviously and make the acute adverse reaction rate insignificantly.

    Full Text Available BackgroundPostmastectomy adjuvant therapy is used to prevent locoregional recurrence and improve overall breast cancer specific survival rates. However, it can adversely affect the cosmetic results of reconstruction. Therefore, the authors examined flap stability and patients' satisfaction with immediate breast reconstruction after adjuvant therapy.MethodsWe retrospectively reviewed the medical records of 204 patients from January 2006 to November 2011. For complication rates, the authors categorized the patients who underwent the immediate breast reconstruction into 4 groups: adjuvant chemotherapy and radiotherapy group, adjuvant chemotherapy only group, adjuvant radiotherapy only group, and the group that did not undergo adjuvant therapy. For comparison of patients' satisfaction, the study was performed with an additional 16 patients who had undergone delayed breast reconstruction.ResultsRegarding complication rates, the group that had undergone adjuvant therapy showed no significant difference compared to the group that did not undergo adjuvant therapy. In evaluating the patients' satisfaction, there was no significant difference.ConclusionsEven after adjuvant therapy, immediate breast reconstruction showed good results with respect to flap stability and patients' satisfaction. Immediate breast reconstruction and adjuvant therapy is a safe and useful option for breast cancer patients.

    Purpose: to evaluate the efficacy of simultaneous postoperative temozolomide radiochemotherapy in glioblastoma patients. Patients and methods: from February 2002 to July 2004, n = 65 patients from 11 German centers with macroscopic complete tumor resection were randomized to receive either postoperative radiotherapy alone (RT, n = 35) or postoperative radiotherapy with simultaneous temozolomide (RT + TMZ, n = 30). Patients were stratified according to age ({<=}/> 50 years) and WHO performance score (0-1 vs. 2). RT consisted of 60 Gy in 30 fractions. In the RT + TMZ arm, oral TMZ was administered daily at a dose of 75 mg/m{sup 2} including weekends (40-42 doses). Adjuvant treatment was not given, but in both arms, patients with recurrent tumors and in good condition (WHO 0-2) were scheduled for salvage chemotherapy with TMZ. Results: the trial was stopped early due to the results of EORTC-study 26981-22981 that showed a survival benefit for the combination of concomitant and adjuvant TMZ compared to radiotherapy alone. In total, 62/65 patients were evaluable. Stratification variables were well balanced ({<=} 50 years 26% vs. 20%, WHO 0-1 91% vs. 100%). Neither overall survival (median 17 vs. 15 months) nor progression-free survival (median 7 vs. 6 months) differed significantly between the two arms. In the RT (RT + TMZ) arm, 76% (62%) of the progressing patients received salvage chemotherapy with TMZ, 36% (50%) had a second resection. There was a time-constant trend for increased general quality of life (EORTC questionnaire QLQ C30) and brain-specific quality of life (EORTC questionnaire B20) in the combined arm. Lymphopenia G3-4 was more frequent (33 vs. 6%) in the RT + TMZ arm. Conclusion: after early closure of this trial, a benefit for progression-free survival for simultaneous TMZ radiochemotherapy alone could not be demonstrated. In both arms, salvage therapies were frequently used and probably had a major effect on overall survival. (orig.)

    Background: Ewing's tumors are sensitive to radio- and chemotherapy. Patients with multifocal disease suffer a poor prognosis. Patients presenting primary bone marrow involvement or bone metastases at diagnosis herald a 3-year disease-free survival below 15%. The European Intergroup Cooperative Ewing's Sarcoma Study (EICESS) has established the following indications for high-dose therapy in advanced Ewing's tumors: Patients with primary multifocal bone disease, patients with early (<2 years after diagnosis) or multifocal relapse. Patients and Method: As of 1987, 83 patients have been treated in the EICESS group, 39 of them at the transplant center in Duesseldorf, who have been analyzed here. All individuals received 4 courses of induction chemotherapy with EVAJA and stem cell collection after course 3 and 4. Consolidation radiotherapy of the involved bone compartments was administered in a hyperfractionated regimen 2 times 1.6 Gy per day, up to 22.4 Gy simultaneously to course 5 and 22.4 Gy to course 6 of chemotherapy. The myeloablative chemotherapy consisted of melphalan and etoposide (ME) in combination with 12 Gy TBI (Hyper-ME) oder Double-ME with whole lung irradiation up to 18 Gy (without TBI). Results: The survival probability at 40 months was 31% (44% DOD; 15% DOC). Pelvic infiltration did not reach prognostic relevance in this cohort. Radiotherapy encompassed 75% of the bone marrow at maximum (average 20%). Engraftment was not affected by radiotherapy. Conclusion: High-dose chemotherapy can improve outcome in poor prognostic advanced Ewing's tumors. The disease itself remains the main problem. The expected engraftment problems after intensive radiotherapy in large volumes of bone marrow can be overcome by stem cell reinfusion. (orig.) [German] Hintergrund: Ewing-Tumoren sind radio- und chemosensibel. Im metastasierten Stadium ist die Prognose schlecht.

    2002-08-01

    Background: The aim was to ascertain whether many hundreds of clinical reports over the last decade are consistent with the prediction of a poorer outcome in cancer patients with p53 abnormalities treated with cytotoxic drugs and radiation. Material and method: There are 301 studies on the influence of p53 overexpression published through summer 2000, in which chemotherapy or radiotherapy was used alone or in combination with surgery. From 45 reports meeting stringent selection rules, comparison groups are identified in whom the same measure of outcome was reported for the same treatment applied to the same tumor, with results corrected for important prognostic factors. Metaanalysis techniques are then applied to the comparison groups. Attention was limited to reports using immunohistochemical techniques, to form comparison groups of sufficient size. Results: Four comparison groups were identified by treatment and endpoint: (1) Stage-I-III breast cancer (surgery and chemotherapy, disease-free survival, seven studies); (2) stage I-III breast cancer (surgery and chemotherapy, overall survival, six studies); (3) stage II-IV head and neck cancer (radiotherapy and chemotherapy, overall survival, five studies); (4) FIGO I-IV ovarian cancer (surgery and chemotherapy, overall survival, six studies). In the breast (disease-free survival) and ovarian (overall survival) comparison groups, the hazard ratio for a deleterious effect of p53 overexpression was significant or marginally significant, depending on assumed ranges for unreported hazard ratios in non-significant studies. Conclusions: Despite the many caveats related to metaanalysis applied to retrospective data, high variability of immunohistochemical technique, etc., a nearly significant negative effect of p53 overexpression on outcome of treatment with cytotoxic drugs and radiation emerges in the few studies where heterogeneity can be sufficiently reduced or accounted for.

Settings and Design: Data from patients with squamous cell cancer of oral cavity, oropharynx, hypopharynx, and larynx (AJCC, 2010 Stage II to IVB; who received hypofractionated (n = 30 or conventionally fractionated (n = 30 radiotherapy, with or without chemotherapy, between January 2010 to June 2011 were retrieved and retrospectively analyzed. Materials and Methods: In conventional arm (Arm A, each patient received 70 Gy at 2 Gy per fraction over 7 weeks, along with concurrent cisplatin (100 mg/m 2 on days 1, 22, and 43 for locally advanced stage. In hypofractionated arm (Arm B, each patient received 55 Gy at 2.75 Gy per fraction over 4 weeks, along with concurrent cisplatin (100 mg/m 2 on days 1 and 22 for locally advanced stage. The end points were tumor response, acute and late toxicities, overall survival (OS, and diseases-free survival (DFS. Results: The tumor response distribution was comparable - 24 (80% patients in arm A and 23 (76% in arm B achieved a complete response. Significant differences in frequencies of acute grade ≥ 2 skin toxicity, mucositis were found, with higher frequencies in Arm B. Higher frequencies of late grade ≥ 2 dysphagia, laryngeal edema, xerostomia, and confluent mucositis were encountered in Arm B at 6 months from start of chemoradiation. However, OS, DFS, and loco-regional recurrence rates were comparable between the two arms. Conclusions: Hypofractionated radiotherapy can achieve similar tumor response to conventionally fractionated radiotherapy in HNSCC, although with some increase of toxicity.

    Endometrial cancer is one of the most common gynecological malignancies and the standard treatment modality has not been established.To assess the efficacy and tolerability of a sandwich method consisted of chemotherapy followed by involved field irradiation and additional chemotherapy for the treatment of advanced endometrial cancer.The Medline, Embase, Cochrane, and China National Knowledge Infrastructure (CNKI) Library were searched to identify the relevant literature published between 1970 and September 2014. A meta-analysis was performed to evaluate progression-free survival (PFS), overall survival (OS), and toxicity.A total of 5 articles were subjected to this meta-analysis. The pooled 3-year PFS and OS of patients with advanced endometrial cancer treated with the "sandwich" method was 68% (95% CI: 0.60-0.77) with no heterogeneity (I = 0.00%, P = 0.77) among the studies and 75% (95% CI: 0.61-0.89) with significant heterogeneity (I = 71.8%, P = 0.01), respectively. Pooled analysis of toxicity was not performed because of the substantial heterogeneity.Sequential chemotherapy and radiotherapy in the sandwich method is both efficacious and well tolerated. Large-scale randomized controlled trials (RCTs) are necessary in the future.

    High indexes of loco-regional recurrence in patients with rectal cancer have stimulated the search of complementary therapy. Since the sixties, neo adjuvant radiotherapy has gained space in order to reduce local recurrence and to increase the survival of these patients. Recently some publications have pointed out the importance of associating chemotherapy and total excision of mesorectum to the radiotherapy in the same way. The results of large prospective researches are expected to determine the exact role of this association. (author)

    To evaluate the long-term disease control, survival, and complications after definitive radiotherapy (RT) alone or combined with adjuvant chemotherapy with or without planned neck dissection for base of tongue squamous cell carcinoma (SCC). We retrospectively reviewed the medical records of 467 patients treated at the University of Florida with definitive RT alone or combined with adjuvant chemotherapy between 1964 and 2011 for base of tongue SCC. Median follow-up was 5.6 years. Median total dose to the primary site was 74.4 Gy. Eighty-seven patients (19%) were treated with once-daily fractionation, and 380 (81%) received altered fractionation schedules. Intensity-modulated RT was used in 128 patients (27%). Chemotherapy was administered to 173 (37%) patients. Planned neck dissection after RT was performed in 226 patients (48%). Data regarding p16 pathway activation were available for 25 patients. At 5 years, the local, local-regional, and regional control rates were 85.5%, 80.0%, and 90.0%, respectively. The 5-year overall, cause-specific, and distant metastasis-free survival rates were 59.1%, 71.5%, and 84.1%, respectively. Sixty-four patients (14%) developed one or more severe late complications. Fifty patients (11%) required late gastrostomy tube placement. This study supports the continued use of RT alone or combined with adjuvant chemotherapy for patients with base of tongue SCC, as this treatment yields high rates of cause-specific survival and disease control, with a relatively low rate of late complications. 4.

    Evaluated in this study were the feasibility and the efficacy of concurrent low dose fractionated radiotherapy (LD-FRT) and chemotherapy as palliative treatment for recurrent/progressive glioblastoma multiforme (GBM). Eligible patients had recurrent or progressive GBM, Karnofsky performance status ≥70, prior surgery, and standard radiochemotherapy treatment. Recurrence/progression disease during temozolomide (TMZ) received cisplatin (CDDP; 30 mg/m{sup 2} on days 1, 8, 15), fotemustine (FTM; 40 mg/m{sup 2} on days 2, 9, 16), and concurrent LD-FRT (0.3 Gy twice daily); recurrence/progression after 4 months from the end of adjuvant TMZ were treated by TMZ (150/200 mg/m{sup 2} on days 1-5) concomitant with LD-FRT (0.4 Gy twice daily). Primary endpoints were safety and toxicity. A total of 32 patients were enrolled. Hematologic toxicity G1-2 was observed in 18.7% of patients and G3-4 in 9.4%. One patient (3.1%) had complete response, 3 (9.4%) had partial response, 8 (25%) had stable disease for at least 8 weeks, while 20 patients (62.5%) experienced progressive disease. The clinical benefit was 37.5%. Median progression-free survival (PFS) and overall survival (OS) were 5 and 8 months, respectively. Survival rate at 12 months was of 27.8%. LD-FRT and chemotherapy for recurrent/progressive GBM have a good toxicity profile and clinical outcomes, even though further investigation of this novel palliative treatment approach is warranted.

    Full Text Available Background. Radiotherapy (RT in patients with pancreatic cancer is still a controversial subject and its benefit in inoperable stages of locally advanced pancreatic cancer (LAPC, even after induction chemotherapy, remains unclear. Modern radiation techniques such as image-guided radiotherapy (IGRT and intensity-modulated radiotherapy (IMRT may improve effectiveness and reduce radiotherapy-related toxicities. Methods. Patients with LAPC who underwent radiotherapy after chemotherapy between 09/2004 and 05/2013 were retrospectively analyzed with regard to preradiation chemotherapy (PRCT, modalities of radiotherapy, and toxicities. Progression-free (PFS and overall survival (OS were estimated by Kaplan-Meier curves. Results. 15 (68% women and 7 men (median age 64 years; range 40–77 were identified. Median duration of PRCT was 11.1 months (range 4.3–33.0. Six patients (27% underwent conventional RT and 16 patients (73% advanced IMRT and IGRT; median dosage was 50.4 (range 9–54 Gray. No grade III or IV toxicities occurred. Median PFS (estimated from the beginning of RT was 5.8 months, 2.6 months in the conventional RT group (conv-RT, and 7.1 months in the IMRT/IGRT group (P=0.029; median OS was 11.0 months, 4.2 months (conv-RT, and 14.0 months (IMRT/IGRT; P=0.141. Median RT-specific PFS for patients with prolonged PRCT > 9 months was 8.5 months compared to 5.6 months for PRCT 9 months group, with 19.0 months compared to 8.5 months in the PRCT  <  9 months group (P=0.049. Conclusions. IGRT and IMRT after PRCT are feasible and effective options for patients with LAPC after prolonged preradiation chemotherapy.

    For locally-advanced uterine cancer clinically extending to the cervix, two treatment paradigms exist: surgical staging radical hysterectomy with tailored adjuvant therapy or neoadjuvant therapy followed by a less extensive simple hysterectomy. Currently, insufficient data exists to guide consensus guidelines and practical application of preoperative radiotherapy. Retrospective IRB approved cohort study from 1999 to 2014 of 36 endometrial cancer patients with clinical involvement of cervix±parametria treated with neoadjuvant external beam radiotherapy (45-50.4Gy in 25-28 fractions) and image-based HDR brachytherapy (5-5.5Gy times 3-4 fractions)±chemotherapy followed by extrafascial hysterectomy performed at a median of 6weeks after radiotherapy. All patients had clinical cervical extension, 50% also had parametria extension, and 31% had nodal involvement. At the time of surgery 91% had no clinical cervical involvement, 58% had no pathologic cervical involvement, and all had margin negative resection. The pathologic complete response rate was 24%. Median follow-up from the time of surgery was 20months (range: 0-153). The 3-year local control, regional control, distant control, disease free survival and overall survival rates were 96%, 89%, 84%, 73%, and 100%. The 3-year rate of grade 3 complications was 11%, with no grade 4+ toxicity. Neoadjuvant radiation therapy±chemotherapy followed by extrafascial hysterectomy appears to be a viable option for patients with endometrial cancer clinically extending to the cervix and parametria. The HDR brachytherapy schema of 5-5.5Gy times 3-4 fractions, for a cumulative EQD2 of 60-70Gy, is well tolerated with high rates of clinical and pathological response. Copyright © 2014 Elsevier Inc.

    Full Text Available Background Postmastectomy adjuvant therapy is used to prevent locoregional recurrenceand improve overall breast cancer specific survival rates. However, it can adversely affectthe cosmetic results of reconstruction. Therefore, the authors examined flap stability andpatients’ satisfaction with immediate breast reconstruction after adjuvant therapy.Methods We retrospectively reviewed the medical records of 204 patients from January2006 to November 2011. For complication rates, the authors categorized the patients whounderwent the immediate breast reconstruction into 4 groups: adjuvant chemotherapyand radiotherapy group, adjuvant chemotherapy only group, adjuvant radiotherapy onlygroup, and the group that did not undergo adjuvant therapy. For comparison of patients’satisfaction, the study was performed with an additional 16 patients who had undergonedelayed breast reconstruction.Results Regarding complication rates, the group that had undergone adjuvant therapyshowed no significant difference compared to the group that did not undergo adjuvanttherapy. In evaluating the patients’ satisfaction, there was no significant difference.Conclusions Even after adjuvant therapy, immediate breast reconstruction showed goodresults with respect to flap stability and patients’ satisfaction. Immediate breast reconstructionand adjuvant therapy is a safe and useful option for breast cancer patients.

    Highlights: • Glycidyl nitrate (GLYN) is a NO generating small molecule and has ability to release NO on bioactivation in tumor cells. • GLYN-induced intracellular NO generation was attenuated by NO scavengers. • GLYN increases tumor blood flow in tumor-bearing animal model. • GLYN significantly increased the anti-tumor efficacy of cisplatin and radiation therapy in mice. • GLYN is well tolerated with no obvious systemic toxicities at its effective therapeutic doses in preclinical animal studies. - Abstract: Selective release of nitric oxide (NO) in tumors could improve the tumor blood flow and drug delivery for chemotherapeutic agents and radiotherapy, thereby increasing the therapeutic index. Glycidyl nitrate (GLYN) is a NO generating small molecule, and has ability to release NO on bioactivation in SCC VII tumor cells. GLYN-induced intracellular NO generation was significantly attenuated by NO scavenger carboxy-PTIO (cPTIO) and NAC. GLYN significantly increases tumor blood flow, but has no effect on the blood flow of normal tissues in tumor-bearing mice. When used with cisplatin, GLYN significantly increased the tumor growth inhibition effect of cisplatin. GLYN also had a modest radiosensitizing effect in vitro and in vivo. GLYN was well tolerated and there were no acute toxicities found at its effective therapeutic doses in preclinical studies. These results suggest that GLYN is a promising new drug for use with chemotherapy and radiotherapy, and provide a compelling rationale for future studies of GLYN and related compounds.

    Eleven inoperable patients with advanced esophageal carcinoma were treated with chemotherapy (carboplatin, 5-FU, vindesine) and concomitant radiotherapy. Two patients (T2) received this treatment due to their poor general condition and refusal of operation, and 9 patients for infiltration of tumor into the adjacent organs (T4). Administration of carboplatin (30 mg/body) and 5-FU (250 mg/body) together with radiotherapy (1.8 Gy/d) for 5 days a week was performed. This chemoradiation therapy was carried out for 5 consecutive weeks. In addition, vindesine (1-3 mg/body) was administered in the 1st and 4th week. After evaluation, endoscopic balloon dilatation was performed in 6 patients with stenosis of the esophagus. The general response rate was 80%. CR was noted in 2 patients of T2 but 1 patient of T4 developed severe leucopenia and immunosuppression, and died of septic MOF. All but the MOF case could take enough food orally following the endoscopic dilatation. The 1-year survival rate in the T4 group (45%) was significantly better than the non-treatment group (0%). In conclusion, this treatment is beneficial for patients with inoperable esophageal carcinoma to obtain a satisfactory QOL and survival rate. (author)

    This study aimed to assess the effects of body mass index (BMI) on survival in cervical cancer patients who had undergone surgery and radiotherapy (RT). We retrospectively reviewed the medical records of 70 cervical cancer patients who underwent surgery and RT from 2007 to 2012. Among them, 40 patients (57.1%) had pelvic lymph node metastases at the time of diagnosis. Sixty-seven patients (95.7%) had received chemotherapy. All patients had undergone surgery and postoperative RT. Median BMI of patients was 22.8 kg/m2 (range, 17.7 to 35.9 kg/m2). The median duration of follow-up was 52.3 months (range, 16 to 107 months). Twenty-four patients (34.3%) showed recurrence. Local failure, regional lymph nodal failure, and distant failure occurred in 4 (5.7%), 6 (8.6%), and 17 (24.3%) patients, respectively. The 5-year actuarial pelvic control rate was 83.4%. The 5-year cancer-specific survival (CSS) and disease-free survival (DFS) rates were 85.1% and 65.0%, respectively. The presence of pelvic lymph node metastases (n = 30) and being overweight or obese (n = 34, BMI ≥ 23 kg/m2) were poor prognostic factors for CSS (p = 0.003 and p = 0.045, respectively). Of these, pelvic lymph node metastasis was an independent prognostic factor (p = 0.030) for CSS. Overweight or obese cervical cancer patients showed poorer survival outcomes than normal weight or underweight patients. Weight control seems to be important in cervical cancer patients to improve clinical outcomes.

    Conclusion: Cervical cancer survivors treated with radiotherapy had worse sexual functioning than did those treated with radical hysterectomy and lymph node dissection. Appropriate measures like Pelvic exercises, Yoga, vaginal dilators, vaginal cream should be used to decrease radiotherapy related side effects on sexual functioning. Cervical cancer survivors treated with surgery alone can expect overall quality of life and sexual function not unlike that of peers without a history of cancer.

    OBJECTIVE To examine fatigue and quality of life (QOL) in breast cancer patients undergoing chemotherapy or radiotherapy.METHODS A self-report survey derived from the Chinese version of Brief Fatigue Inventory, the Functional Assessment of Chronic Illness Therapy for Breast Cancer, and the Medical Outcomes Study Social Support Survey. Descriptive statistics was used to examine the intensity of fatigue and the prevalence of severe fatigue. Multivariate analysis of variance was used to determine factors that affect the five domains of QOL among the participants.RESULTS The majority of the participants (n = 261) perceived a mild level of fatigue, but 35.6% of them suffered severe fatigue. Fatigue had a significantly negative association with all domains of QOL except social/family wellbeing. The participants who were receiving chemotherapy, undergoing curative treatment and having inadequate social support were more likely to have poorer QOL in all five domains (after adjustment for age).CONCLUSION Although the majority of the participants experienced a mild level of fatigue, there was a substantial group of breast cancer patients who perceived their fatigue as severe. The findings of this study showed that fatigue had a detrimental effect on the various aspects of the participants'QOL. Demographic and clinical characteristics of breast cancer patients who were at risk of getting poorer QOL were identified. The results of the study demonstrate that we should enhance healthcare professionals' awareness of the importance of symptom assessment, and provide them with information for planning effective symptom-management strategies among this study population.

    Full Text Available Abstract Background The molecular characteristics associated with the response to treatment in glioblastomas (GBMs remain largely unknown. We performed a retrospective study to assess the genomic characteristics associated with the response of GBMs to either first-line chemotherapy or radiation therapy. The gene expression (n = 56 and genomic profiles (n = 67 of responders and non-responders to first-line chemotherapy or radiation therapy alone were compared on Affymetrix Plus 2 gene expression arrays and BAC CGH arrays. Results According to Verhaak et al.'s classification system, mesenchymal GBMs were more likely to respond to radiotherapy than to first-line chemotherapy, whereas classical GBMs were more likely to respond to first-line chemotherapy than to radiotherapy. In patients treated with radiation therapy alone, the response was associated with differential expression of microenvironment-associated genes; the expression of hypoxia-related genes was associated with short-term progression-free survival ( 10 months. Consistently, infiltration of the tumor by both CD3 and CD68 cells was significantly more frequent in responders to radiotherapy than in non-responders. In patients treated with first-line chemotherapy, the expression of stem-cell genes was associated with resistance to chemotherapy, and there was a significant association between response to treatment and p16 locus deletions. Consistently, in an independent data set of patients treated with either radiotherapy alone or with both radiotherapy and adjuvant chemotherapy, we found that patients with the p16 deletion benefited from adjuvant chemotherapy regardless of their MGMT promoter methylation status, whereas in patients without the p16 deletion, this benefit was only observed in patients with a methylated MGMT promoter. Conclusion Differential expression of microenvironment genes and p16 locus deletion are associated with responses to radiation therapy and to first

    The prevalence of malnutrition in lung cancer patients across a variety of treatment modalities and disease stages ranges from 45% to 69%. Malnutrition is associated with poorer clinical outcomes in cancer patients. This systematic review examined whether dietary counseling or oral supplements during chemotherapy and/or radiotherapy in patients with lung cancer affect patient or clinical outcomes. Relevant nutrition intervention studies from 1980 to March 2012 were identified. Articles meeting predetermined inclusion/exclusion criteria were critically appraised and included in the review. The outcomes of interest included dietary intake, weight, nutritional status, quality of life, functional status, treatment response, and survival. Five eligible studies were identified including 3 randomized controlled trials, 1 historical cohort, and 1 case series. These studies suggest dietary counseling improves energy and protein intake during chemotherapy in patients with lung cancer but has no benefit to other outcomes during chemotherapy. There is insufficient evidence regarding the effect on patient or clinical outcomes during radiotherapy. Randomized trials examining dietary counseling in patients with lung cancer during radiotherapy are required.

    We analyzed 52 cases of advanced or recurrent cancer of the cervix treated by intra-arterial infusion chemotherapy (IAIC) with or without radiotherapy. IAIC regimen was separated into two groups: Group I consisted of 5-FU + MMC {+-} ADR (30 cases) and Group II of CDDP + MMC {+-} 5-FU (22 cases). The tip of the catheter was placed in the bifurcation of abdominal aorta or the bilateral internal iliac arteries (7 cases). The overall response rate (CR + PR) was 71%, 87% in patients given radiotherapy, 50% in those without radiotherapy, and 100% in primary cases. The five-year survival rate was 20% in primary cases, 14% in recurrent cases, 3% in Group I and 38% in Group II (p=0.00182) by chemotherapy regimen. Severe (more than grade III) hematological acute side effect was 48% for all cases, but recovered by interruption of drugs. In 7 cases in which the tip of the catheter was placed in internal iliac arteries, there were severe skin ulcers in 2 cases and severe pain of leg or gluteal region requiring narcotics in 2 cases. These data suggest that IAIC mainly with cisplatin with or without radiotherapy is one of the effective treatments for advanced or recurrent cervix cancer. But we should check the blood flow distribution periodically, and control the concentration of drugs. (author)

    AIM: To investigate the change in expression of p53, Bcl-2, and Bax genes in human colon cancer cells transplanted into nude mice after hyperthermia,chemotherapy, radiotherapy, thermochemotherapy,thermoradiotherapy and thermochemoradiotherapy.METHODS: Human colon cancer cell line (HT29)was transplanted into the hind limbs of nude mice.Under laboratory simulated conditions of hyperthermia (43℃, 60 min), the actual radiation doses and doses of mitomycin C (MMC) were calculated in reference to the clinical radiotherapy for human rectal cancer and chemotherapy prescription for colon cancer. The mice were divided into 6 groups according to the treatment approaches: hyperthermia, chemotherapy,radiotherapy, thermochemotherapy, thermoradiotherapy,and thermochemoradiotherapy. The mice were sacrificed at different time points and the tumor tissue was taken for further procedures. The morphologic changes in membrane, cytoplasm and nuclei of tumor cells of p53, Bcl-2, and Bax after treatment, were observed by immunohistochemistry staining.RESULTS: All of the six treatment modalities downregulated the expression of p53, Bcl-2 and up-regulated the expression of Bax at different levels. The combined therapy of hyperthermia, with chemotherapy, and/or irradiation showed a greater effect on down-regulating the expression of p53 (0.208 ± 0.009 vs 0.155 ± 0.0115,P < 0.01) and Bcl-2 (0.086 ± 0.010 vs 0.026 ± 0.0170,P < 0.01) and up-regulating Bax expression (0.091 ±0.0013 vs 0.207 ±0.027, P < 0.01) compared with any single therapy.CONCLUSION: Hyperthermia enhances the effect of radio- and chemotherapy on tumors by changing the expression of apoptosis genes, such as p53, Bcl-2 and Bax.

    Purpose: To determine the maximal tolerated biologic dose intensification of radiotherapy using fractional dose escalation with temozolomide (TMZ) chemotherapy in patients with newly diagnosed glioblastoma multiforme. Methods and Materials: Patients with newly diagnosed glioblastoma multiforme after biopsy or resection and with adequate performance status, bone marrow, and organ function were eligible. The patients underwent postoperative intensity-modulated radiotherapy (IMRT) with concurrent and adjuvant TMZ. All patients received a total dose of 60 Gy to the surgical cavity and residual tumor, with a 5-mm margin. IMRT biologic dose intensification was achieved by escalating from 3 Gy/fraction (Level 1) to 6 Gy/fraction (Level 4) in 1-Gy increments. Concurrent TMZ was given at 75 mg/m{sup 2}/d for 28 consecutive days. Adjuvant TMZ was given at 150-200 mg/m{sup 2}/d for 5 days every 28 days. Dose-limiting toxicity was defined as any Common Terminology Criteria for Adverse Events, version 3, Grade 3-4 nonhematologic toxicity, excluding Grade 3 fatigue, nausea, and vomiting. A standard 3+3 Phase I design was used. Results: A total of 16 patients were accrued (12 men and 4 women, median age, 69 years; range, 34-84. The median Karnofsky performance status was 80 (range, 60-90). Of the 16 patients, 3 each were treated at Levels 1 and 2, 4 at Level 3, and 6 at Level 4. All patients received IMRT and concurrent TMZ according to the protocol, except for 1 patient, who received 14 days of concurrent TMZ. The median number of adjuvant TMZ cycles was 7.5 (range, 0-12). The median survival was 16.2 months (range, 3-33). One patient experienced vision loss in the left eye 7 months after IMRT. Four patients underwent repeat surgery for suspected tumor recurrence 6-12 months after IMRT; 3 had radionecrosis. Conclusions: The maximal tolerated IMRT fraction size was not reached in our study. Our results have shown that 60 Gy IMRT delivered in 6-Gy fractions within 2 weeks with

    The objective of the study is to determine whether surgery influences the outcome of stage IV ovarian cancer. The study design is as follows: From May 1995 to December 2000, 129 patients with FIGO stage IV ovarian cancer, recruited in 42 centers, were prospectively included in GINECO first-line randomized studies of platinum-based regimens with paclitaxel administered simultaneously or sequentially. In all, 109 were eligible for this study. Standard peritoneal cytoreductive surgery was defined as a procedure including at least total hysterectomy, bilateral salpingo-oophorectomy, omentectomy, and peritoneal debulking. Surgery was considered optimal if residual lesions were smaller than 1 cm. The Kaplan-Meier method was used to compare survival. Initial abdominopelvic cytoreductive surgery was considered standard in 55 (54%) patients. Abdominopelvic surgery was optimal in 29 patients and nonoptimal in 26. Twenty-two (22%) patients had a simple biopsy, and 25 (24%) patients underwent substandard surgery. Twenty-two of these 47 patients without initial standard surgery underwent a second surgical procedure, and 17 of the 22 patients completed standard surgery. The median overall survival time in the entire population was 24.3 months (95% confidence interval [CI], 19.5-29.1 months). Patients treated without a cytoreductive surgical procedure had significantly worse median survival (15.1 months; 95% CI, 5.4-24.9 months) than patients who had optimal primary surgery (22.9 months; 95% CI, 15.6-30.1 months), nonoptimal primary surgery (27.1 months; 95% CI, 21.2-32.9 months), or neoadjuvant chemotherapy followed by surgery (45.5 months; 95% CI, 23.5-67.5 months) (P= .001). In conclusion, this study shows a significant benefit of debulking surgery in stage IV ovarian cancer patients who responded to neoadjuvant chemotherapy. Neoadjuvant chemotherapy can help to select patients for surgery.

    Breast conservative surgery after neoadjuvant chemotherapy intends to remove any residual tumor with negative margins. The purpose of this study was to analyze the preoperative clinical-pathological factors influencing the margin status after conservative surgery in breast cancer patients receiving neoadjuvant chemotherapy. A retrospective study of 91 breast cancer patients undergoing neoadjuvant chemotherapy (92 breast lesions) during the period 2006 to 2013. A Cox regression analysis to identify baseline tumor characteristics associated with positive margins after breast conservative surgery was performed. Of all cases, 71 tumors were initially treated with conservative surgery after neoadjuvant chemotherapy. Pathologic exam revealed positive margins in 16 of the 71 cases (22.5%). The incidence of positive margins was significantly higher in cancers with initial size >5cm (P=.021), in cancers with low tumor grade (P=.031), and in patients with hormone receptor-positive cancer (P=.006). After a median follow-up of 45.2 months, 7 patients of the 71 treated with conservative surgery had disease recurrence (9.8%). There was no significant difference in terms of disease-free survival according to the margin status (P=.596). A baseline tumor size >5cm, low tumor grade and hormone receptor-positive status increase the risk for surgical margin involvement in breast conservative surgery after neoadjuvant chemotherapy.

    Purpose Neoadjuvant therapy is able to reduce local recurrence in rectal cancer. Immediate surgery after short course radiotherapy allows only for minimal downstaging. We investigated the effect of delayed surgery after short-course radiotherapy at different time intervals before surgery, in patients affected by rectal cancer. Methods From January 2003 to December 2013 sixty-seven patients with the following characteristics have been selected: clinical (c) stage T3N0 ≤ 12 cm from the anal verge and with circumferential resection margin > 5 mm (by magnetic resonance imaging); cT2, any N, CRM+ve who resulted unfit for chemo-radiation, were also included. Patients underwent preoperative short-course radiotherapy with different interval to surgery were divided in three groups: A (within 6 weeks), B (between 6 and 8 weeks) and C (after more than 8 weeks). Hystopatolgical response to radiotherapy was measured by Mandard’s modified tumor regression grade (TRG). Results All patients completed the scheduled treatment. Sixty-six patients underwent surgery. Fifty-three of which (80.3%) received a sphincter saving procedure. Downstaging occurred in 41 cases (62.1%). The analysis of subgroups showed an increasing prevalence of TRG 1–2 prolonging the interval to surgery (group A—16.7%, group B—36.8% and 54.3% in group C; p value 0.023). Conclusions Preoperative short-course radiotherapy is able to downstage rectal cancer if surgery is delayed. A higher rate of TRG 1–2 can be obtained if interval to surgery is prolonged to more than 8 weeks. PMID:27548058

    Treatment of stage IA non-Hodgkin`s lymphoma (NHL) of Waldeyer`s ring remains controversial, probably because of the small number of patients and the scarcity of controlled studies. Between 1981 and 1991, 316 patients with stage I NHL of Waldeyer`s ring were randomised for treatment with radiotherapy alone (extended fields), 101 patients; combined chemotherapy with a regimen of CHOP (cyclophosphamide, vincristine, doxorubicin, and prednisone) or CHOP-like (epirubicin instead of doxorubicin), 106 patients; and combined therapy (radiotherapy followed by the same combination chemotherapy), 109 patients. Median follow-up was 6.8 years. Complete response was achieved in 93, 87 and 97%, respectively. Relapses were least frequent in patients treated with combination therapy. The 5-year rate for failure-free survival was 48% for radiation therapy, 45% for the patients who were treated with chemotherapy, which was statistically significantly less than the 83% for patients treated with combined therapy (P < 0.001). Overall survival was also better in the combined therapy arm: 90%, statistically different to 58% for the patients treated with chemotherapy alone and 56% for patients treated with radiation therapy (P < 0.001). Toxicity was mild and late side-effects were not observed in any patients. From these results combined therapy should be considered as the best therapeutic approach in patients with localised NHL of Waldeyer`s ring. (author).

    Full Text Available In the October of 1996, Lance Armstrong, celebrated cyclist and one of the greatest athletes the world has ever seen, at the age of 24, was diagnosed with metastatic testicular cancer with disease having already spread to his abdomen, lungs and brain. Lance underwent four cycles of chemotherapy, actually the pretty standard one, pioneered at the Indiana University and not only did he get completely cured of his cancer, he remains extremely well till date, 12 years later. He sure did have a few adverse effects during those cycles of chemotherapy in the form of nausea, vomiting, weakness and fall in blood count but he knew and experienced them only for a short transient time and emerged triumphant and strong. In fact, he went on to win six awe-inspiring and incredible successive Tours de France victories from 1999-2005, one of the most grueling sporting events testing the endurance of the very fittest. After his retirement, he has been so inspired that he has completely devoted himself to educate people about the common myths about cancer, and promised to raise awareness and generate money for furthering research into surgery, radiation therapy and chemotherapy for cancer through his foundation. He says "I am indebted to the doctors, nurses and medicine and would want to pay them back for all their energy and caring." In his successful journey of overcoming cancer, he captures the essence of its treatment so well by declaring "Pain is temporary, it may last a minute, or an hour, or a day, or a year, but eventually, it will subside and something else will take its place. If I quit, however, it will last forever".

    A prospective comparative study of the alveolar bone resorption after teeth extraction was achieved in a series of 79 patients in order to analyze macroscopically the possible consequences of radiotherapy and chemotherapy on the toothless edges. After quarterly coronal and sagittal X-rays for two years, this study enhances quite a similar vertical resorption for the radiation and chemotherapy-treated patients as well as for the witness patients. The alveolar bone resorption progression also appears unaltered by anti cancerous treatments. In both cases, a resorption stabilization can be clearly seen after 6 months according to dental extractions. The vertical alveolar bone resorption is more important in incisor and canin regions. The anti cancerous treatments may not have significant disastrous consequences as fas as available bone amount is concerned, on a post prosthetic restoration.

    Objective: To evaluate the efficacy of adjuvant chemotherapy after radical surgery for non-small cell lung cancer (NSCLC). Methods: Seventy patients with NSCLC (stage Ⅰ-Ⅲ) undergone radical surgery were randomized into two groups: 35 patients received adjuvant chemotherapy with cyclophosphamide (CTX)300 mg/m2, vincristine (VCR) 1.4% mg/m2, adriamycin (ADM) 50 mg/m2, lomustine (CCNU) 50 mg/m2 d1,cisplatin (DDP) 20 mg/m2, d1-5, for 4 cycles, and followed by oral Ftorafur (FT-207) 600-900 mg/d for 1year (adjuvant chemotherapy group). The other 35patients received surgical treatment only (surgery group). Results: The overall 5-year survival rate was 48.6% in the adjuvant chemotherapy group, and 31.4%in the surgery group, respectively. The difference between the two groups was not statistically significant (P>0.05). The 5-year survival rate of patients in stage Ⅲwas 44.0% and 20.8% received surgery with and without adjuvant chemotherapy, respectively. The difference between the two groups was statistically significant (P<0.025). The 5-year survival rate of patients in stage Ⅰ-Ⅱ in the two groups was 60.0% and 54.5%, respectively (P>0.75). Conclusion: Postoperative adjuvant chemotherapy in NSCLC can improve survival, for those patients in stage Ⅲ, it suggests significantly 5-year survival rate in the adjuvant chemotherapy group was higher than that in the surgery alone group.

    Preoperative short-course radiotherapy with immediate surgery improves local control in patients with rectal cancer. Tumor responses are smaller than those described with radiochemotherapy. Preliminary data associate this lower response to the short period until surgery. The aim of this study is to analyze the response to preoperative short-course radiotherapy and its correlation with the interval to surgery especially analyzing patients with mesorectal fascia involvement. A total of 155 patients with locally advanced rectal cancer treated with preoperative radiotherapy (5×5Gy) were retrospectively analyzed. Tumor response in terms of rates of complete pathological response, downstaging, tumor regression grading and status of the circumferential resection margin were quantified. The mean interval from radiotherapy to surgery was 23 days. The rate of complete pathological response was 2.2% and 28% experienced downstaging (stage decreased). No differences between these rates and interval to surgery were detected. Eighty-eight patients had magnetic resonance imaging for staging (in 31 patients the mesorectal fascia was involved).The mean time to surgery in patients with involvement of the fascia and R0 surgery was 27 days and 16 days if R1 (P=.016). The cutoff of 20 days reached the highest probability of achieving a free circumferential resection margin between patients with mesorectal fascia involvement, with no statistically significant differences: RR 3.036 95% CI=(0.691-13.328), P=.06. After preoperative short-course radiotherapy, an interval>20 days enhances the likelihood of achieving a free circumferential resection margin in patients with mesorectal fascia involvement.

    Context Maintaining excellent cure rates in pediatric Hodgkin lymphoma while minimizing toxicity. Objective To evaluate the efficacy of 4 cycles of vinblastine, Adriamycin, methotrexate, and prednisone (VAMP) in patients with favorable risk Hodgkin lymphoma who achieve a complete response after 2 cycles and do not receive radiotherapy. Design, Setting, and Patients Multi-institutional, unblinded, non-randomized single group phase II clinical trial to assess the need for radiotherapy based on early response to chemotherapy. Eighty-eight eligible patients with Hodgkin lymphoma stage I and II (< 3 nodal sites, no B symptoms, mediastinal bulk, or extranodal extension) enrolled between March 3, 2000 through December 9, 2008. Data frozen March 12, 2012. Interventions Patients who achieved a complete response (n=47) after 2 cycles received no radiotherapy, and those with less than complete response (n=41) were given 25.5 Gy involved field radiotherapy. Main Outcome Measures 2-year event-free survival was the primary outcome measure. A 2-year event-free survival of greater than 90% was desired, and 80% was considered to be unacceptably low. Results Two-year event-free survival was 90.8% (95% CI, 84.7% – 96.9%); for patients who did not require radiotherapy it was 89.4% (95% CI, 80.8% – 98%), compared with 92.5% (95% CI, 84.5% – 100%) for those who did (P=0.61). Most common acute side effects were neuropathic pain (2% of patients), nausea/vomiting (3% of patients), neutropenia (32% of cycles), and febrile neutropenia (2% of patients). Nine patients (10%) were hospitalized 11 times (3% of cycles) for febrile neutropenia or non-neutropenic infection. Long term side effects after radiotherapy were asymptomatic compensated hypothyroidism in 9 patients (10%), osteonecrosis and moderate osteopenia in 2 patients each, subclinical pulmonary dysfunction in 12 patients (26%) and asymptomatic left ventricular dysfunction in 4 patients (5%).

    Five years overall survival in osteosarcoma patients is around 70%, although in patients with metastatic disease it is only 10-30%. The objective of this study was to analyze overall survival and prognostic factors in a group of patients with metastatic osteosarcoma treated with surgical removal of the lung metastases. A retrospective review from our oncology data base revealed 38 patients treated between 1992 and 2006. The mean age at diagnosis was 18 ± 9.4 years (3-45) and mean follow-up was 57 ± 53.8 months (12-231). All patients were treated with chemotherapy and oncologic resection of the primary tumor and surgical removal of the lung metastases. We analyzed overall survival and prognostic factors: age, gender, site, time of metastasis, local recurrences, number of lung metastasis and chemotherapy response (necrosis). Overall survival of the entire series was 29% at 5 years (CI 95%: 14.5-43.5) and 26% at 10 years (CI 95%: 12-40). Significant difference in 5 year overall survival was found between good and bad responders to chemotherapy, 53% (IC 95%: 28-78) vs. 8% (IC 95%: 0-20) (p = 0.0008). No statistically significant relationship between other prognostic factors analyzed was observed. Five and ten years overall survival rates in osteosarcoma patients with lung metastasis treated with chemotherapy and surgically resection is poor. Patients with good response to chemotherapy have better prognosis.

    Purpose: To retrospectively analyze results of concurrent chemoradiotherapy (CCRT) using gemcitabine (GEM) for unresectable pancreatic adenocarcinoma. Methods and Materials: Records of 108 patients treated with concurrent external beam radiotherapy (EBRT) and GEM were reviewed. The median dose of EBRT in all 108 patients was 50.4 Gy (range, 3.6-60.8 Gy), usually administered in conventional fractionations (1.8-2 Gy/day). During radiotherapy, most patients received GEM at a dosage of 250 to 350 mg/m{sup 2} intravenously weekly for approximately 6 weeks. After CCRT, 59 patients (54.6%) were treated with adjuvant chemotherapy (AC), mainly with GEM. The median follow-up for all 108 patients was 11.0 months (range, 0.4-37.9 months). Results: Initial responses after CCRT for 85 patients were partial response: 26 patients, no change: 51 patients and progressive disease: 8 patients. Local progression was observed in 35 patients (32.4%), and the 2-year local control (LC) rate in all patients was 41.9%. Patients treated with total doses of 50 Gy or more had significantly more favorable LC rates (2-year LC rate, 42.9%) than patients treated with total doses of less than 50 Gy (2-year LC rate, 29.6%). Regional lymph node recurrence was found in only 1 patient, and none of the 57 patients with clinical N0 disease had regional lymph node recurrence. The 2-year overall survival (OS) rate and the median survival time in all patients were 23.5% and 11.6 months, respectively. Patients treated with AC had significantly more favorable OS rates (2-year OS, 31.8%) than those treated without AC (2-year OS, 12.4%; p < 0.0001). On multivariate analysis, AC use and clinical T stage were significant prognostic factors for OS. Conclusions: CCRT using GEM yields a relatively favorable LC rate for unresectable pancreatic adenocarcinoma, and CCRT with AC conferred a survival benefit compared to CCRT without AC.

    The new technique of ileocolic free flap reconstruction provides a better quality of life in terms of swallowing and speech for patients who have undergone laryngopharyngectomy with concomitant chemotherapy and radiotherapy (CCRT). To compare and contrast the swallowing and speech outcomes of patients who underwent total laryngopharyngectomy with ileocolic free flap reconstruction and to analyze the survival rate after surgery and CCRT. This was a follow-up study of 12 patients with advanced (stages III, IVA and IVB) laryngeal and hypopharyngeal cancer who underwent major surgery, CCRT (with one exception) and ileocolic free flap reconstruction. All patients were able to tolerate single-stage combined management comprising total laryngopharyngectomy with or without radical neck dissection plus ileocolic free flap reconstruction and postoperative CCRT (with one exception), without immediate morbidity or mortality. Eleven patients were diagnosed with hypopharyngeal cancer and one with laryngeal cancer. The mean interval between surgery and CCRT was 34.1 days. The mean follow-up period was 16.5 months. Four patients died during the follow-up period as a result of local recurrence (n=2), distant metastasis (n=1) and suicide (n=1). One patient was alive with disease despite neck recurrence.

    Peritoneal carcinomatosis in gastric cancer is associated with a dismal prognosis. Systemic chemotherapy is not effective because of the existence of a blood-peritoneal barrier. Cytoreductive surgery and intraperitoneal chemotherapy can improve survival and quality of life in selected patients. Patient selection for this multimodal approach is one of the most critical issues, and calls for interdisciplinary evaluation by radiologists, medical and surgical oncologists, and anaesthetists. This article sets forth criteria for selection of gastric cancer patients suffering from peritoneal carcinomatosis.

    The purpose of the present paper was to evaluate treatment outcome after conservative breast surgery or mastectomy followed by simultaneous adjuvant radiotherapy and cyclophosphamide, methotrexate and fluorouracil (CMF) therapy. Two hundred and sixty eight (268) patients were treated at two Australian and two New Zealand centres between 1981 and July 1995. One hundred and sixty-nine patients underwent conservation surgery and 99 had mastectomies. Median follow-up was 53 months. Conventionally fractionated radiation was delivered simultaneously during the first two cycles of CMF, avoiding radiation on the Fridays that the intravenous components of CMF were delivered. In conservatively treated patients, 5-year actuarial rates of any recurrence, distant recurrence and overall survival were 34.5 {+-} 5.2%, 25.4 {+-} 4.5% and 75.5 {+-} 4.8%, respectively. Crude incidence of local relapse at 4 years was 6.3% and at regional/distant sites was 26.3%. Highest grades of granulocyte toxicity (< 0.5 x 10{sup 9}/L), moist desquamation, radiation pneumonitis and persistent breast oedema were recorded in 10.7, 8.5, 8.9 and 17.2%, respectively. In patients treated by mastectomy, 5-year actuarial rates of any recurrence, distant recurrence and overall survival were 59.7 {+-} 7.3%, 56.7 {+-} 7.4% and 50.1 {+-} 7%. The crude incidence of local relapse at 4 years was 5.6% and at regional/distant sites it was 45.7%. The issue of appropriate timing of adjuvant therapies has become particularly important with the increasing acknowledgement of the value of anthracycline-based regimens. For women in lower risk categories (e.g. 1-3 nodes positive or node negative), CMF may offer a potentially better therapy, particularly where breast-conserving surgical techniques have been used. In such cases CMF allows the simultaneous delivery of radiotherapy with the result of optimum local control, without compromise or regional or systemic relapse rates.

    Although the technical developments of radiotherapy have been remarkable, there are currently few reports on the treatment results of radiotherapy for local recurrence of rectal cancer treated with surgery alone as initial treatment in this three-dimensional conformal radiotherapy era. Thus, we retrospectively evaluated the treatment results of radiotherapy for local recurrence of rectal cancer treated with surgery alone as the initial treatment. Thirty-two patients who underwent radiotherapy were enrolled in this study. The dose per fraction was 2.0–3.5 Gy. Because the treatment schedule was variable, the biological effective dose (BED) was calculated. Local control (LC) and overall survival (OS) rates from the completion of radiotherapy were calculated. The 1-, 2-, 3-, 4-, and 5-year LC rates were 51.5%, 24.5%, 19.6%, 19.6%, and 13.1%, respectively. LC rates were significantly higher for the high BED group (≥75 Gy10) than for the lower BED group (<75 Gy10). All patients who reported pain achieved pain relief. The duration of pain relief was significantly higher for the high BED group than for the lower BED group. The 1-, 2-, 3-, 4-, and 5-year OS rates were 82.6%, 56.5%, 45.2%, 38.7%, and 23.2%, respectively. There was a trend toward higher OS rates in with higher BED group compared to lower BED group. For patients with unresectable locally recurrent rectal cancer treated with surgery alone, radiotherapy is effective treatment. The prescribed BED should be more than 75 Gy10, if the dose to the organ at risk is within acceptable levels.

    Preoperative radiotherapy (pRT) for rectal cancer may reduce local recurrence and improve survival. This study was undertaken to assess a selective policy of pRT in rectal cancer. The aim was to determine whether patients likely to have involved circumferential margins (CRM) could be reliably selected for pRT using clinical criteria. We have used CRM and delay in surgery as outcome measures. Seventy-nine patients with rectal cancer were assessed for preoperative radiotherapy using clinical criteria. Twelve of 26 (46%) pRT patients had positive CRM compared with three of 53 (5.6%) who did not receive pRT (P benefit from radiotherapy and has avoided excessive delays prior to surgery. However, almost half of the pRT patients did not have involved CRM. With improved imaging techniques we may be able to refine our selection criteria further.

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

    The aim of this study was to describe the impact of postoperative adjuvant treatment modalities and identify risk factors associated with recurrence and survival rates in women diagnosed with early stage type II endometrial cancer and carcinosarcoma. In this retrospective study, patients diagnosed with early stage (stages I-II) carcinosarcoma and type II endometrial cancer were reviewed. All women underwent comprehensive surgical staging. Postoperative treatment options of chemotherapy (CT), radiotherapy (RT), observation (OBS) and chemotherapy-radiotherapy (CT-RT) combination were compared in terms of recurrence and survival outcome. In CT-RT treatment arm, recurrence rate was found as 12.5% and this result is significantly lower than the other treatment approaches (P = 0.01 CT alone: 33.3%, RT alone: 26.7%, OBS: 62.5%). Three-year disease free survival(DFS) rate and overall survival (OS) rate were statistically higher for the group of women treated with combination of CT-RT (92-95%) compared to the women treated with RT alone (65-72%), treated with CT alone (67-74%) and women who received no adjuvant therapy (38-45%). The multivariate analysis revealed that carcinosarcoma histology was associated with shortened DFS and OS (P = 0.001, P = 0.002). On the other hand, being at stage Ia (P = 0.01, P = 0.04) and receiving adjuvant treatment of CT-RT combination (P = 0.005, P = 0.002) appeared to lead to increased DFS and OS rates. We identified that a combination treatment of chemotherapy and radiotherapy is superior compared to other postoperative adjuvant treatment approaches concerning PFS, OS and recurrence rates in stages I-II of type II endometrial cancers and uterine carcinosarcoma. © 2016 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

    To evaluate the outcomes of adjuvant chemotherapy administered alone or with radiotherapy in a "sandwich" protocol in patients with advanced endometrial cancer. The authors retrospectively reviewed the clinical records of patients with staged III - IV disease who received adjuvant chemotherapy (docetaxel plus carboplatin) administered alone or interposed with radiotherapy between January 2004 and August 2010. Of the 35 study patients, 10 (28.6%) had stage IIIA disease, 15 (42.9%) had IIIC1 disease, 7 (20.0%) had IIIC2 disease and 3 (8.6%) had IVB disease. Nine (90.0%) of the 10 patients with stage IIIA disease received four to six cycles of adjuvant docetaxel and carboplatin chemotherapy alone. All 25 patients with stage IIIC - IVB disease and 1 patient with stage IIIA disease received radiotherapy sandwiched between chemotherapy cycles (total, three to six cycles). The 3-year progression-free survival (PFS) and overall survival (OS) rates were 73.0 and 87.0%, respectively, for all patients. For patients with stage IIIC - IVB disease, the 3-year PFS and OS rates were 62.4 and 81.8%, respectively. Combination chemotherapy with docetaxel and carboplatin interposed with radiotherapy is efficacious and well tolerated for stage IIIC - IVB endometrial cancer. Adjuvant chemotherapy alone with docetaxel and carboplatin might be sufficient for stage IIIA disease.

    Short-term radiotherapy (STR) for rectal cancer (RC) has rarely been used in Spain. The aim of the present study is to describe oncological results after RTC and surgery for RC. This is a retrospective analysis of a consecutive series of patients treated with STR and surgery for RC (1999-2012). Epidemiological data, staging, complications of STR, STR-surgery interval, surgical approach, rate of anastomotic/perineal wound dehiscence, and pathological data (regression degree and staging) were collected. Global survival, disease free survival, local recurrence rate and incidence of toxicity, response and complications of combined treatment are reported. Of 1229 patients treated, 209 patients received STR and surgery. The median follow-up was 6.2 years. Mean age was 68 years and 66% of the patients were men. A total of 88% were cT3-4 and 44% cN+17 (8.1%) patients had resectable synchronous metastases. Acute and chronic toxicity due to STR was 4 weeks. Seven patients (3.3%) presented complete response. Nine (4.3%) patients presented an local recurrence rate. Global survival at 5, 10 and 15 years was 67.8, 49.2 and 37.5%, respectively. Disease free survival at 5, 10 and 15 years was 66.1, 47.1 and 33%, respectively. The results compare favorably with multicentric historical series. STR offers certain advantages that could be increased by increasing the STR-surgery interval and/or interspersed with sequential chemotherapy. Copyright © 2017 AEC.

    Purpose: this study was undertaken to evaluate the efficacy of two regimens of chemoradiotherapy in the treatment of locally advanced head and neck cancer. Methods: from 1992 to 1997, 127 patients with locally advanced head and neck cancer (stage III-IV) were randomized. Sixty-six patients (group a), 42 male and 24 female, with a median age of 48 years (range 40-72) received during radiotherapy two courses (1.-6. week) of chemotherapy with carbo-platin (300 mg/m{sup 2} day 1) and etoposide (60 mg/m{sup 2} days 1 to 3). Sixty-one patients (group b), 40 male and 21 female, with a median age of 51 years (range 42-69) received two cycles of chemotherapy with 5 FU (750 mg/m{sup 2} days 1 to 5) and MIT C ( 10 mg/m{sup 2} day 1). The median dose of radiotherapy was 60 Gy (range 55-66 Gy) 180 cGy /d 5w. Results: the actuarial five-year survival rate(Kaplan-Meier) was 38 % for group a (CBDCA+etoposide+RT) and 25 % for group b (5FU+MIT C+RT). The difference was statistically significant (p = 0.036). Toxicity group a: mucositis G III in 41 patients and G IV in 16; dysphagia G III in 46 patients and IV in 5; leukopenia in 24 patients; 28 patients required nutritional therapy. Toxicity group b: mucositis G III in 38 patients and G IV in 17; dysphagia G III in 48 patients and G IV in 3; leukopenia in 23 patients; 25 patients needed nutritional therapy. Conclusions: the data of the actuarial survival five-year rate suggest that concomitant chemotherapy in group a (CBDCA+etoposide+RT) is better than the concomitant chemotherapy in group b (5FU+MIT C+RT).

    A 38-year-old woman with early stage invasive breast cancer was treated with wide excision of the tumor, axillary lymph node dissection, and breast irradiation. Three years later, she gave birth to a normal baby. She attempted breast feeding and had full lactation from the untreated breast. The irradiated breast underwent only minor changes during pregnancy and postpartum but produced small amounts of colostrum and milk for 2 weeks postpartum. There are only a few reports of lactation after breast irradiation. These cases are reviewed, and possible factors affecting breast function after radiotherapy are discussed. Because of scant information available regarding its safety for the infant, nursing from the irradiated breast is not recommended.

    Ovarian function was evaluated in 11 women 16 to 43 years of age at treatment who received doxorubicin, cyclophosphamide, and high doses of methotrexate with or without radiotherapy in adjuvant therapy of soft tissue sarcoma. Five women (16-33 yr old) who received chemotherapy alone or combined with radiotherapy only at sites distant from the ovaries (chest wall, thigh, and leg) had minimal menstrual irregularities or temporary cessation of menses during therapy; cyclic menses returned promptly after therapy. Gonadotropin levels (expressed as means +/- SD (follicle-stimulating hormone (FSH), 10 +/- 5 mlU/ml; luteinizing hormone (LH), 10 +/- 4 mlU/ml) and 17 beta-estradiol (E2) levels (means +/- SD, 208 +/- 147 pg/ml) were normal. By contrast, 4 older women (ages 36-43 yr) who received similar treatment developed persistent amenorrhea with postmenopausal levels of gonadotropin (FSH, 108 +/- 29 mlU/ml; LH, 72 +/- 19 mlU/ml) and E2 (19 +/- 8 pg/ml). Two additional women (ages 21 and 39 yr) who received radiation (7,000 rad) to the pelvis plus chemotherapy developed prompt cessation of menses and became functional castrates (FSH, 77 and 80 mlU/ml; LH, 40 and 58 mlU/ml; E2, 10 and 19 pg/ml). However, this result would be expected from the radiation dose alone. The data demonstrated that ovarian dysfunction may follow the use of doxorubicin, cyclophosphamide, and high doses of methotrexate and that the injury is age related.

    Severe stomatitis caused by chemotherapy and radiotherapy is accompanied by severe pain and results in a poor quality of life. We used a spray preparation of indomethacin (IM; 0.25% IM dissolved in phosphate buffer, pH 7.4), a nonsteroidal anti-inflammatory drug (NSAID) to control the pain associated with stomatitis at the University of Tsukuba Hospital. This review specifically aimed to collect information on the use of the IM spray preparation, from our previous studies, to facilitate its proper use in a hospital setting. On studying the stability of the IM spray preparation, we concluded that the preparation should be kept in the refrigerator for daily use, and that it can be stored for at least 2 months at 4°C, and for 24 months at -20°C. To evaluate the efficacy of the IM spray preparation, we retrospectively surveyed its analgesic effects. Using the 10-grade Visual Analogue Scale in 23 patients, we found that pain associated with stomatitis was reduced from 10 to 4.7 after application of the spray. In conclusion, our study results on the stability and efficacy of the IM spray preparation have led to the proper use of the spray in cancer patients with stomatitis caused by chemotherapy and radiotherapy.

    The purpose of this study is to evaluate the treatment outcomes of adjuvant radiotherapy using vaginal brachytherapy (VB) with a lower dose per fraction and/or external beam radiotherapy (EBRT) following surgery for patients with stage I endometrial carcinoma. The subjects were 43 patients with the International Federation of Gynecology and Obstetrics (FIGO) stage I endometrial cancer who underwent adjuvant radiotherapy following surgery between March 2000 and April 2014. Of these, 25 received postoperative VB alone, while 18 received postoperative EBRT to the whole pelvis; 3 of these were treated with EBRT plus VB. The median EBRT dose was 50.0 Gy (45.0-50.4 Gy) and the VB dose was 24 Gy in 6 fractions. Tumor dose was prescribed at a depth of 5 mm from the cylinder surface and delivered twice per week. The median follow-up period for all patients was 57 months (range, 9 to 188 months). Five-year disease-free survival (DFS) and overall survival (OS) for all patients were 92.5% and 95.3%, respectively. Adjuvant radiotherapy was performed according to risk factors and stage IB, grade 3 and lymphovascular invasion were observed more frequently in the EBRT group. Five-year DFS for EBRT and VB alone were 88.1% and 96.0%, respectively (p = 0.42), and 5-year OS for EBRT and VB alone were 94.4% and 96%, respectively (p = 0.38). There was no locoregional recurrence in any patient. Two patients who received EBRT and 1 patient who received VB alone developed distant metastatic disease. Two patients who received EBRT had severe complications, one each of grade 3 gastrointestinal complication and pelvic bone insufficiency fracture. Adjuvant radiotherapy achieved high DFS and OS with acceptable toxicity in stage I endometrial cancer. VB (with a lower dose per fraction) may be a viable option for selected patients with early-stage endometrial cancer following surgery.

    The purpose of this study is to evaluate the treatment outcomes of adjuvant radiotherapy using vaginal brachytherapy (VB) with a lower dose per fraction and/or external beam radiotherapy (EBRT) following surgery for patients with stage I endometrial carcinoma. The subjects were 43 patients with the International Federation of Gynecology and Obstetrics (FIGO) stage I endometrial cancer who underwent adjuvant radiotherapy following surgery between March 2000 and April 2014. Of these, 25 received postoperative VB alone, while 18 received postoperative EBRT to the whole pelvis; 3 of these were treated with EBRT plus VB. The median EBRT dose was 50.0 Gy (45.0–50.4 Gy) and the VB dose was 24 Gy in 6 fractions. Tumor dose was prescribed at a depth of 5 mm from the cylinder surface and delivered twice per week. The median follow-up period for all patients was 57 months (range, 9 to 188 months). Five-year disease-free survival (DFS) and overall survival (OS) for all patients were 92.5% and 95.3%, respectively.

    Full Text Available Objective To investigate the clinical efficacy of neoadjuvant chemotherapy combined with breast-conserving surgery for locally advanced breast cancer. Methods Eighty-one patients with locally advanced breast cancer were selected from those who were admitted into 309 Hospital of PLA from January 2009 to October 2013, consisting of 65 patients in stage Ⅲa and 16 in stage Ⅲb, and they were treated with neoadjuvant chemotherapy combined with breast-conserving surgery. The clinical efficacy [complete response (CR, partial response (PR, stable disease (SD and progress disease (PD] was observed during follow-up. Results All the patients were followed-up for 12-60 months with a median of 34 months. There were 12 CR patients (14.8%, including 4 with pathological complete response (4.9%, and 52 PR patients (64.2%, 17 SD patients (21.0%. No PD was observed. The overall response rate(ORR was 79.0%(64/81. After follow-up for 12-60 months (median 34 months, distant metastasis to the lung, liver, meninges and bone occurred in 3 patients (3.7%, 3/81 and 1 of them died. Forty-eight patients received breastconserving surgery. The local recurrence rate was 6.3% (3/48. Assessment of cosmetic result was carried out in 48 patients who received breast-conserving surgery and comprehensive treatment for one year, and excellent results were obtained in 14.6% (7/48, good in 43.8% (21/48, and poor in 41.7% (20/48. Conclusions The therapeutic efficacy of locally advanced breast cancer is satisfactory by neoadjuvant chemotherapy and breast-conserving surgery. Standardization of excision and postoperative radiotherapy, systemic comprehensive treatment is the key to the success of the treatment. DOI: 10.11855/j.issn.0577-7402.2015.06.14

    Full Text Available PURPOSE: It deserves investigation whether induction chemotherapy (IC followed by intensity-modulated radiotherapy (IMRT is inferior to the current standard of IMRT plus concurrent chemotherapy (CC in locoregionally advanced nasopharyngeal carcinoma. METHODS: Patients who received IC (94 patients or CC (302 patients plus IMRT at our center between March 2003 and November 2012 were retrospectively analyzed. Propensity-score matching method was used to match patients in both arms at equal ratio. Failure-free survival (FFS, overall survival (OS, distant metastasis–free survival (DMFS, and locoregional relapse–free survival (LRFS were assessed with Kaplan-Meier method, log-rank test, and Cox regression. RESULTS: In the original cohort of 396 patients, IC plus IMRT resulted in similar FFS (P = .565, OS (P = .334, DMFS (P = .854, and LRFS (P = .999 to IMRT plus CC. In the propensity-matched cohort of 188 patients, no significant survival differences were observed between the two treatment approaches (3-year FFS 80.3% vs 81.0%, P = .590; OS 93.4% vs 92.1%, P = .808; DMFS 85.9% vs 87.7%, P = .275; and LRFS 93.1% vs 92.0%, P = .763. Adjusting for the known prognostic factors in multivariate analysis, IC plus IMRT did not cause higher risk of treatment failure, death, distant metastasis, or locoregional relapse. CONCLUSIONS: IC plus IMRT appeared to achieve comparable survival to IMRT plus CC in locoregionally advanced nasopharyngeal carcinoma. Further investigations were warranted.

    In recent years, lymphadenitis caused by atypical mycobacteria (also called nontuberculous mycobacteria [NTMB] or, more recently, environmental) have played a significant role in the differential diagnosis of adenitis in non-immunocompromised children. To describe the clinical and pathological findings in childhood NTMB adenitis and study the possible usefulness of antimicrobial therapy in addition to surgery. We present eight cases of neck lymphadenitis occurring over a 5-year period. All of the children received combined chemotherapy, and six also underwent surgery. Of the two remaining patients, the parents of one child refused surgery and a watchful approach was adopted in the other. Complete clinical recovery was achieved in all patients except one who did not undergo surgery. Prolonged administration of two antibiotics (of which one must be clarithromycin) in addition to surgery was well-tolerated and could be useful in patients with NTMB neck lymphadenitis.

    Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) is associated with prolonged survival for appropriately selected patients with peritoneal dissemination of abdominal malignancies. CRS and HIPEC has been criticized for perceived high rates of morbidity and mortality. Morbidity and mortality rates of CRS and HIPEC, however, do not appear dissimilar to those of other large abdominal surgeries, particularly when relevant patient and operative factors are accounted for. The risk of morbidity and mortality following this surgery for a given individual can be predicted in part by a variety of patient and operative factors. While strong data are lacking, the limited data that exists on the matter suggests that the independent contribution of the heated intraperitoneal chemotherapy to CRS and HIPEC morbidity is relatively small. A more thorough understanding of the patient and operative factors associated with CRS and HIPEC morbidity and mortality, as well as the specific complications related to the intraperitoneal chemotherapy, can better inform clinicians in multidisciplinary teams and patients alike in the decision-making for this surgery.

    Objective: To investigate the clinical efficacy of endoscopic surgery for extensive osteoradionecrosis (ORN) of skull base in patients with nasopharyngeal carcinoma (NPC) after radiotherapy. Methods: Seventeen patients diagnosed as ORN of skull base after radiotherapy for NPC and underwent endoscopic surgery were retrospectively studied with their clinic data. Results: Based on the CT and endoscopic examination, all patients had large skull base defects with bone defects averaged 7.02 cm(2) (range, 3.60 - 14.19 cm(2)). Excepting for curetting the sequestra, endoscopic surgery was also used to repair the wound or to protect the internal carotid artery with flap in 12 patients. No bone reconstructions were conducted in all patients with the bone defects of skull base. CT examinations were taken after endoscopic surgery when required. The postoperative follow-up ranged from 8 months to 6 years (average, 14 months). Aside from 1 patient with delayed cerebrospinal fluid (CSF), others had no related complications. Conclusions: The patients with extensive ORN can be treated with endoscopic surgery to curette the necrotic bone of skull base, and endoscopic reconstruction provides an alternative technique. It may not be necessary to reconstruct the bone defects at skull base, however, the exposed important structures of skull base, such as internal carotid artery, need to repair with soft tissue such as flap.

    Full Text Available Background: Anthracycline based regiments and/or taxanes and adjuvant radiotherapy; the main modalities of treatment for breast cancers are associated with deterioration of pulmonary functions and progressive pulmonary toxicities. Aim: Assessment of pulmonary toxicities and impact on pulmonary functions mainly in terms of decline of forced vital capacity (FVC and the ratio of forced expiratory volume (FEV in 1 Second and FEV1/FVC ratio with different treatment times and follow ups in carcinoma breast patients receiving anthracycline and/or taxane based chemotherapy and radiotherapy. Materials and methods: A prospective single institutional cohort study was performed with 58 breast cancer patients between January 2011 to July 2012 who received either anthracycline based (37 patients received 6 cycles FAC= 5 FU, Adriamycin, Cyclophosphamide regime and radiotherapy or anthracycline and taxane based chemotherapy (21 patients received 4cycles AC= Adriamycin, Cyclophosphamide; followed by 4 cycles of T=Taxane and radiotherapy. Assessment of pulmonary symptoms and signs, chest x-ray and pulmonary function tests were performed at baseline, midcycle, at end of chemotherapy, at end radiotherapy, at 1 and 6 months follow ups and compared. By means of a two-way analysis of variance (ANOVA model, the course of lung parameters across the time points was compared. Results and Conclusion: Analysis of mean forced vital capacities at different points of study times showed definitive declining pattern, which is at statistically significant level at the end of 6th month of follow up (p=0.032 .The FEV1/FVC ratio (in percentage also revealed a definite decreasing pattern over different treatment times and at statistically significant level at 6th month follow up with p value 0.003.

    A 68 year-old man was given a diagnosis of lung cancer of the right upper lobe (small cell carcinoma, T 4 N 2 M 0, stage IIIB) in February 1991. The tumor diminished after chemotherapy and radiotherapy. In February 1992, a partial resection of the lower lobe of the right lung was performed because of the appearance of a metastatic tumor. In September 1994, squamous cell carcinoma developed in the lower part of the esophagus, but disappeared after radiotherapy. In February 1998, a diagnosis of myelodysplastic syndrome was made. Two months later, the patient had an attack of acute myelocytic leukemia and died of cardiac tamponade. An autopsy determined that both the lung cancer and esophageal cancer had disappeared. Acute myelocytic leukemia and plasmacytoma of lymph nodes in the irradiated area were confirmed. These were regarded as secondary malignancies induced by chemotherapy and radiotherapy. (author)

    The aim of this study was to assess and compare adjuvant chemotherapy followed by either high-dose-rate vaginal vault brachytherapy (VBT) alone or combined with pelvic external beam radiotherapy (EBRT) for International Federation of Gynaecology and Obstetrics stage 1 serous or clear cell (CC) endometrial cancer. Between 2006 and 2012, 84 women with stage 1 serous or CC endometrial cancer were evaluated postoperatively for adjuvant treatment at our hospital. More than 80% of patients had pelvic lymphadenectomy. Patients declining or not completing adjuvant treatments were excluded. Twenty-five women received 4 to 6 cycles of carboplatin/paclitaxel followed by EBRT and VBT. Thirty-two women received 6 cycles of carboplatin/paclitaxel followed by VBT. Locoregional control and toxicities were assessed during follow-up. The 3-year disease-free survival and overall survival rates for the VBT group compared with the EBRT + VBT group were 88% versus 84%, P = 0.6, and 100% versus 94%, P = 0.6, respectively. Only 1 patient in the EBRT + VBT group developed a distant recurrence. One patient had grade 3 toxicity (chronic gastrointestinal [GI] toxicity) in the EBRT + VBT group. Acute grade 1-to-2 GI and grade 1 genitourinary (GU) toxicities were less frequent in the VBT group compared with the EBRT + VBT group (P = 0.008 and P = 0.019, respectively). Late GI and GU toxicities were comparable. Grade 1 vaginal toxicity was similar in both groups. No acute or late grade 2 GU or vaginal toxicities were reported. According to this study, VBT alone seems to be as effective as EBRT and VBT for stage 1 serous and CC endometrial cancer treated with surgery and adjuvant chemotherapy. Furthermore, less acute GI and GU toxicities were seen in the VBT group.

    To determine failure patterns and survival outcomes of T4N0-1 non-small cell lung cancer (NSCLC) treated with definitive radiotherapy. Ninety-five patients with T4N0-1 NSCLC who received definitive radiotherapy with or without chemotherapy from May 2003 to October 2014 were retrospectively reviewed. The standard radiotherapy scheme was 66 Gy in 30 fractions. The main concurrent chemotherapy regimen was 50 mg/m2 weekly paclitaxel combined with 20 mg/m2 cisplatin or AUC 2 carboplatin. The primary outcome was overall survival (OS). Secondary outcomes were failure patterns and toxicities. The median age was 64 years (range, 34 to 90 years). Eighty-eight percent of patients (n = 84) had an Eastern Cooperative Oncology Group performance status of 0-1, and 42% (n = 40) experienced pretreatment weight loss. Sixty percent of patients (n = 57) had no metastatic regional lymph nodes. The median radiation dose was EQD2 67.1 Gy (range, 56.9 to 83.3 Gy). Seventy-one patients (75%) were treated with concurrent chemotherapy; of these, 13 were also administered neoadjuvant chemotherapy. At a median follow-up of 21 months (range, 1 to 102 months), 3-year OS was 44%. The 3-year cumulative incidences of local recurrence and distant recurrence were 48.8% and 36.3%, respectively. Pretreatment weight loss and combined chemotherapy were significant factors for OS. Acute esophagitis over grade 3 occurred in three patients and grade 3 chronic esophagitis occurred in one patient. There was no grade 3-4 radiation pneumonitis. Definitive radiotherapy for T4N0-1 NSCLC results in favorable survival with acceptable toxicity rates. Local recurrence is the major recurrence pattern. Intensity modulated radiotherapy and radio-sensitizing agents would be needed to improve local tumor control.

    Full Text Available Herein, we will review the available literature about robot-assisted radical prostatectomy in patients who have undergone prostate surgery or radiotherapy. Current data about this topic consists of small case series with limited follow-up. Despite being technically demanding, robot-assisted radical prostatectomy (RARP can be considered feasible in either setting. Prostate surgery or prostatic irradiation should not be considered as a contraindication for robot-assisted radical prostatectomy. Nevertheless, patient counseling about the possible complications and the need for reintervention is of extreme importance in this patient population. Early oncologic and functional results of RARP performed in case of radiorecurrent prostate cancer look promising. Regarding postprostate surgery RARP, some series have reported comparable results, while some have demonstrated more inferior outcomes than those of naive cases. In order to assess the exact functional and oncologic outcome of RARP in patients with previous prostate surgery and radiotherapy, studies enrolling higher number of patients and providing longer follow-up data are needed.

    The coexistence of pregnancy and cancer is a challenging situation for the physician. Chemotherapy and radiotherapy are often necessary, depending on the type and stage of cancer at diagnosis. When applying such treatment, several key points concerning the health of the fetus must be carefully monitored. Meanwhile, if the appropriate treatment is delayed until postpartum, the mother's life may be at risk. Historically, the mother's health was placed above that of the fetus. This concept has changed, and harmonization of maternal and fetal health is now considered ideal. Numerous reports have shown the safe use of chemotherapy especially during the second and third trimesters of pregnancy. In 2004 our department treated seven cases of simultaneous cancer and pregnancy, leading us to review the use of chemotherapy and radiotherapy during pregnancy and the repercussions on neonatal outcome.

A 50-year-old female with SCLC who had limited disease and achieved full response after treatment presented with acute pancreatitis during her follow-up. The radiologic studies revealed a small area causing obliteration of the pancreatic duct without mass in the pancreatic neck, and endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA confirmed the metastasis of SCLC. The patient was treated successfully with systemic chemotherapy and radiotherapy delivered to pancreatic field. In SCLC, cases of MIAP can be encountered with conventional computed tomography with no mass image, and positron emission tomography and EUS-FNA can be useful for diagnosis of such cases. Aggressive systemic and local treatment can prolong survival, especially in patients with good performance status.

    Ovarian function was evaluated in 11 women 16 to 43 years of age at treatment who received doxorubicin, cyclophosphamide, and high doses of methotrexate with or without radiotherapy in adjuvant therapy of soft tissue sarcoma. Five women (16-33 yr old) who received chemotherapy alone or combined with radiotherapy only at sites distant from the ovaries (chest wall, thigh, and leg) had minimal menstrual irregularities or temporary cessation of menses during therapy; cyclic menses returned promptly after therapy. Gonadotropin levels (expressed as means +/- SD) (follicle-stimulating hormone (FSH), 10 +/- 15 mlU/ml; luteinizing hormone (LH), 10 +/- 4 mlU/ml) and 17 ..beta..-estradiol (E/sub 2/) levels (means +/- SD, 208 +/- 147 pg/ml) were normal. By contrast, 4 older women (ages 36-43 yr) who received similar treatment developd persistent amenorrhea with postmenopausal levels of gonadotropin (FSH, 109 +/- 29 mlU/ml; LH, 72 +/- 19 mlU/ml) and E/sub 2/ (19 +/- 8 pg/ml). Two additional women (ages 21 and 39 yr) who received radiation (7000 rad) to the pelvis plus chemotherapy developed prompt cessation of menses and became functional castrates (FSH, 77 and 80mlU/ml; LH, 40 and 58 mlU/ml; E/sub 2/, 10 and 19 pg/ml). However, this result would be expected from the radiation dose alone. The data demonstrated that ovarian dysfunction may follow the use of doxorubicin, cyclophosphamide, and high doses of methotrexate and that the injury is age related.

    Purpose: To evaluate the role of radiotherapy (RT) and prognostic factors in 62 patients with brain metastases from transitional cell carcinoma (TCC) of the urinary bladder. Patients and Methods: 62 patients received either RT (n = 49), including whole-brain radiotherapy (WBRT) and/or stereotactic radiosurgery (SRS), or surgery (OP) combined with WBRT (n = 13). Overall survival (OS), intracerebral control (ICC) and local control (LC) were retrospectively analyzed. Six potential prognostic factors were assessed: age, gender, number of brain metastases, extracerebral metastases, recursive partitioning analysis (RPA) class, and interval from tumor diagnosis to RT. Results: Median OS and ICC for the entire cohort were 9 and 7 months. No significant difference between RT and OP + RT was found for OS (p = 0.696) and ICC (p = 0.996). On multivariate analysis, improved OS was associated with lack of extracerebral metastases (p < 0.001) and RPA class (p < 0.001), and ICC with the latter (p < 0.001). SRS-incorporating RT resulted in 1-, 2-, and 3-year LC probability of 78%, 66%, and 51%. No association between LC and any of the potential prognostic factors was observed. The results of the subgroup RPA class analyses were similar to the entire cohort. Conclusion: Patient outcome for the RT-alone arm was not significantly different from OP + RT. SRS-incorporating treatment offers excellent LC rates. RPA class and the presence of extracerebral metastases demonstrated a significant prognostic role for survival. The latter should be used as stratification factors in randomized trials and can help define the cohort of patients that may benefit from more aggressive therapies. (orig.)

    The aim of this study was to assess the long-term side effects of central nervous system prophylaxis (high-dose chemotherapy alone vs chemotherapy and CNS radiotherapy) according to the ALL IC-BFM 2002. Thirty-tree children aged 6.7-19.9 years have been studied. The control group consisted of 12 children newly diagnosed with acute lymphoblastic leukemia. We assessed subcortical gray matter volume using automatic MRI segmentation and cognitive performance to identify differences between two therapeutic schemes and patients prior to treatment. Patients treated with chemotherapy and CNS radiotherapy had smaller hippocampi than two other subgroups and lower IQ score than patients treated with chemotherapy alone. Both treated groups, whether with chemotherapy only or in combination with CNS radiotherapy, had significantly lower volumes of caudate nucleus and performed significantly worse on measures of verbal fluency in comparison with patients prior to treatment. There were no differences in the mean volumes of total white matter, total gray matter, thalamus, putamen, and amygdala between the studied groups. In all children treated according to the ALL IC-BFM 2002 with high-dose chemotherapy, both decreased volume of selected subcortical structures and cognitive impairment was observed, especially in children who received chemotherapy in combination with reduced dose CNS radiotherapy. In all children treated according to the ALL IC-BFM 2002 with high-dose chemotherapy, both decreased volume of selected subcortical structures and cognitive impairment were observed, especially in children who received chemotherapy in combination with CNS radiotherapy.

    In order to improve the prognosis of patients with localized non-Hodgkin's lymphomas (NHL) who are treated with radiotherapy (RT), a prospective controlled study utilizing a combined modality approach was carried out in patients with pathologic Stage I-II NHL. After treatment with regional RT, patients in complete remission were randomized to receive either no further therapy or 6 cycles of cyclophosphamide, vincristine and prednisolone (CVP). At 5 years from completion of irradiation, the relapse-free survival was 46.3% after RT and 72.1% after RT plus CVP (P=0.005). The corresponding findings for the overall survival calculated from the beginning of irradiation were 55.8 and 82.8% respectively (P=0.03). The favorable effects of adjuvant chemotherapy on relapse-free survival were statistically significant only in the subgroup with diffuse histology. In patients who relapsed after RT alone, the salvage therapy failed to induce a high incidence of second durable remission. Adjuvant chemotherapy is indicated to improve the curve rate in pathologic stage I-II NHL with diffuse histology when regional RT is utilized.

    .105). Conclusions:Patients with MIBC who overexpress Ki-67 and with negative hormonal receptors have relatively substantial risk of relapse within the first five years after surgery. However, adjuvant chemotherapy can only improve the outcomes of ER(-)/PR(-) patients, but not those who overexpress Ki-67. Further studies with prolonged follow-up of large cohorts are recommended to assess the prognostic significance and treatment of this lesion.

    Treatment outcomes of patients with pelvic recurrence after hysterectomy alone for uterine cervical cancer who received salvage radiotherapy (RT) with or without concurrent chemotherapy were investigated. Salvage RT for recurrent cervical cancer confined to the pelvic cavity after hysterectomy alone was received by 33 patients. The median interval between initial hysterectomy and recurrence was 26 months. Whole-pelvic irradiation was delivered to median dose of 45 Gy, followed by a boost with a median dose of 16 Gy to the gross tumor volume. Cisplatin-based concurrent chemotherapy was administered to 29 patients. The median follow-up period was 53 months for surviving patients. Most patients (97.0%) completed salvage RT of ≥45 Gy. Complete response (CR) was achieved in 23 patients (69.7%). Pelvic sidewall involvement and evaluation with positron-emission tomography-computed tomography were significantly associated with CR. The 5-year progression-free survival (PFS), local control (LC), distant metastasis-free survival (DMFS), and overall survival (OS) rates were 62.7, 79.5, 72.5, and 60.1%, respectively. Initial International Federation of Gynecology and Obstetrics stage, pelvic sidewall involvement, and CR status were significant factors for PFS and OS rates in multivariate analysis. The incidence of severe acute and late toxicities (≥grade 3) was 12.1 and 3.0%, respectively. Aggressive salvage RT with or without concurrent chemotherapy for recurrent cervical cancer confined to the pelvic cavity was feasible, with promising treatment outcomes and acceptable toxicities. However, even more intensive novel treatment strategies should be investigated for patients with unfavorable prognostic factors. (orig.)

    Pathologic downstaging following chemotherapy for stage III-N2 NSCLC is a well-known positive prognostic indicator. However, the predictive factors for locoregional recurrence (LRR) in these patients are largely unknown. Between 1998 and 2008, 153 patients with clinically or pathologically staged III-N2 NSCLC from two cancer centers in the United States were treated with induction chemotherapy and surgery. All had pathologic N0-1 disease, and none received postoperative radiotherapy. LRR were defined as recurrence at the surgical site, lymph nodes (levels 1-14 including supraclavicular), or both. Median follow-up was 39.3 months. Pretreatment N2 status was confirmed pathologically (18.2 %) or by PET/CT (81.8 %). Overall, the 5-year LRR rate was 30.8 % (n = 38), with LRR being the first site of failure in 51 % (22/+99877943). Five-year overall survival for patients with LRR compared with those without was 21 versus 60.1 % (p recurrence (p = 0.021, HR 1.91, 95 % CI 1.1-3.3) but only trended for poorer survival (p = 0.123, HR 1.48, 95 % CI 0.9-2.44). LRR remains high in resected stage III-N2 NSCLC patients after induction chemotherapy and nodal downstaging, particularly in patients with persistent N1 disease.

    The current standard therapeutic option for early stage breast cancer (EBC) employs a multimodality treatment approach including conservative surgery, radiotherapy, chemotherapy, and hormone therapy. The most common adjuvant radiotherapeutic strategy consists of external beam radiation therapy (EBRT) delivered to the whole breast using 1.8-2 Gy fractions given five times a week, up to a total dose of 45-50 Gy over a period of 5 weeks. In recent years, altered schedules employing larger dose per fraction delivered in fewer treatment sessions over a shorter overall treatment time began to be explored. We herein present clinical data on accelerated hypofractionated adjuvant whole-breast radiotherapy delivered on a daily basis for a total treatment time of 20 fractions. Between February 2005 and June 2009, a total of 463 patients underwent hypofractionated accelerated adjuvant radiation after conservative surgery for early breast cancer (pathological stage pTis, pT1 or pT2, pN0-N1). The basic course of radiotherapy consisted of 45 Gy, to the whole breast in 20 fractions with 2.25 Gy/fraction; an additional daily boost dose of 0.25 Gy was concomitantly delivered, to the lumpectomy cavity, for an additional total dose of 5 Gy. The cumulative nominal dose was 50 Gy. At follow-up, patients were examined at 3 and 6 months after the end of radiotherapy and twice a year afterward. Toxicity was scored according to the Common Terminology Criteria for Adverse Events, using the Radiation Therapy Oncology Group /European Organization for Research and Treatment of Cancer toxicity scale. Cosmetic results were assessed in agreement with the Harvard criteria. All the 463 patients treated with the accelerated hypofractionated adjuvant whole-breast radiotherapy schedule achieved at least 6 months' follow-up and subsequently were considered for the present analysis. With a median follow-up of 27 months, 5-year DFS is 93.1%. Only three patients experienced disease recurrence: two of them

    The purpose of this study was to retrospectively review outcomes for patients treated with definitive radiotherapy for carcinoma of the supraglottic larynx at a community hospital and to compare our results with the literature. Treatment records of 46 patients with localized carcinoma of the supraglottic larynx treated from January 1987 through January 2012 were reviewed. Overall, 18 (39%) presented with stage I or II disease, whereas 28 (61%) presented with stage III to IV. In total, 30 patients (65%) were treated using hyperfractionation, whereas 16 (35%) received once-daily fractionation. Twelve patients (26%) received concurrent chemotherapy with weekly cisplatin. The Kaplan-Meier method was used to assess outcomes. The median follow-up for the living patients was 6.7 years (range, 1.7 to 23.1 y). At 5 years, the local-regional control (LRC), ultimate LRC, laryngeal preservation, and overall survival (OS) rates were 70%, 82%, 65%, and 53%, respectively. At 5 years, disease-free survival and cause-specific survival rates were 75% and 76%, respectively. The 5-year OS rates by American Joint Committee on Cancer stage were as follows: I to II, 61%; III, 51%; and IV, 44%. For those receiving concurrent chemotherapy, there was no improvement in 5-year LRC (83% vs. 66%; P=0.4081) or OS (55% vs. 50%; P=0.7697). For those receiving hyperfractionation, there was no improvement in 5-year LRC (75% vs. 63%; P=0.3369) or OS (55% vs. 50%; P=0.4161). Our outcomes are similar to those reported in the literature. Neither hyperfractionation nor chemotherapy appeared to confer a benefit for disease control or OS possibly owing to small sample size and the inherent bias of a retrospective review.

    Six cycles of mechloretamine, vincristine, procarbazine and prednisone (MOPP) chemotherapy were randomly compared with extended field radiotherapy (RT) in 89 adult patients with pathological stage I-II A Hodgkin's disease (HD). 45 patients received RT and 44 were treated with MOPP. Complete remission (CR) was obtained in all patients in the RT group and in 40 of 44 in the MOPP group. 12 patients relapsed in both groups. 10 out of 44 patients treated with MOPP died of HD, compared with only 2 in the RT group. 3 more patients died in the MOPP group following the occurrence of second cancers. 11 out of the 12 (96%) patients relapsing after RT achieved a second CR, compared with 6 out of the 12 (50%) patients relapsing after MOPP. With a median follow-up of more than 8 years, overall survival of patients was significantly better for RT compared with MOPP; 93 and 56% respectively (P < 0.001). The authors conclude RT alone remains the treatment of choice for adult patients with early-stage HD with favourable prognosis. (Author).

    In the present paper, the authors analyze the academic theses of acupuncture for treatment of leucopenia induced by chemo- or radio-therapy. A total of 14 theses are retrieved and all written in Chinese. Quantitative meta-analysis is done for 4 studies of dichotomous data and 5 studies of continuous data. Both of them have positive resuits. Majority of these trials have methodological and/or reporting shortcomings. Overall, the existing evidence supports the value of acupuncture for the treatment of leucopenia induced by chemo- or radio-therapy. However, the evidance is still not fully convincing. There is an urgent need for well planned, large-scale and multiple-center studies to assess the effectiveness and cost-effectiveness of acupuncture under real-life conditions.

    Full Text Available Background In rectal cancer therapy, radiotherapy or chemoradiotherapy (RT/CRT is extensively used preoperatively to (i decrease local recurrence risks, (ii allow radical surgery in non-resectable tumours and (iii increase the chances of sphincter-saving surgery or (iv organ preservation. There is a growing interest among clinicians and scientists to prolong the interval from the RT/CRT to surgery to achieve maximal tumour regression and to diminish complications during surgery.Methods The pros and cons of delaying surgery depending upon the aim of the preoperative RT/CRT are critically evaluated. Results Depending upon the clinical situation, the need for a time interval prior to surgery to allow tumour regression varies. In the first and most common situation (i, no regression is needed and any delay beyond what is needed for the acute radiation reaction in surrounding tissues to wash out can potentially only be deleterious. After short-course RT (5Gyx5 with immediate surgery, the ideal time between the last radiation fraction is 2-5 days since a slightly longer interval appears to increase surgical complications. A delay beyond 4 weeks appears safe; it results in tumour regression including pathologic complete responses, but is not yet fully evaluated concerning oncologic outcome. Surgical complications do not appear to be influenced by the CRT-surgery interval within reasonable limits (about 4-12 weeks, but this has not been sufficiently explored. Maximum tumour regression may not be seen in rectal adenocarcinomas until after several months; thus, a longer than usual delay may be of benefit in well responding tumours if limited or no surgery is planned, as in (iii or (iv, otherwise not.Conclusions A longer time interval is undoubtedly of benefit in some clinical situations but may be counterproductive in most situations.

    Purpose: To analyze the long-term results of a Phase II trial of radiotherapy given immediately after hyperbaric oxygenation (HBO) with multiagent chemotherapy in adults with high-grade gliomas. Methods and Materials: Patients with histologically confirmed high-grade gliomas were administered radiotherapy in daily 2 Gy fractions for 5 consecutive days per week up to a total dose of 60 Gy. Each fraction was administered immediately after HBO, with the time interval from completion of decompression to start of irradiation being less than 15 minutes. Chemotherapy consisting of procarbazine, nimustine, and vincristine and was administered during and after radiotherapy. Results: A total of 57 patients (39 patients with glioblastoma and 18 patients with Grade 3 gliomas) were enrolled from 2000 to 2006, and the median follow-up of 12 surviving patients was 62.0 months (range, 43.2-119.1 months). All 57 patients were able to complete a total radiotherapy dose of 60 Gy immediately after HBO with one course of concurrent chemotherapy. The median overall survival times in all 57 patients, 39 patients with glioblastoma and 18 patients with Grade 3 gliomas, were 20.2 months, 17.2 months, and 113.4 months, respectively. On multivariate analysis, histologic grade alone was a significant prognostic factor for overall survival (p < 0.001). During treatments, no patients had neutropenic fever or intracranial hemorrhage, and no serious nonhematologic or late toxicities were seen in any of the 57 patients. Conclusions: Radiotherapy delivered immediately after HBO with multiagent chemotherapy was safe, with virtually no late toxicities, and seemed to be effective in patients with high-grade gliomas.

    Full Text Available The aim of this study was to evaluate the early acute side effects following radiation and chemotherapy in patients with head and neck cancer (HNC, namely: to ascertain main patient complaints; to investigate saliva properties and to determine the microecology of the oral cavity in patient with HNC before and after radiation and chemotherapy. Eighteen patients with HNC which were prescribed gamma therapy on two buccal submandibular fields combined with close-focus roentgenotherapy and methotrexate as a cytostatic were examined. It was established that 3 weeks after the radio- and chemotherapy 100 % of patients pointed at xerostomia, dysgeusia, disturbances during speech, burning, pricking and itching in oral cavity. After cancer treatment the speed of salivation decreased two times and pH was 15 % lower than before radio and chemotherapy. Anti-cancer treatment caused significant decrease of lysozyme level (34 % lower and secretory immunoglobulin A (1,5 times lower in patients with HNC. After radio and chemotherapy different fungi of Candida genus from oral cavity were inoculated in high concentrations (from 4,0 ± 0.07 to 6,9 ± 0.07 lg CFU/ml, such as С. Аlbicans, C. Kruzei, С. Tropicalis, C. Stellatoidea.Thus significant negative changes from the side of speed and character of salivation, decrease of saliva pH, depression of both non-specific and specific components of immune defense and high contamination of oral mucosa with fungi of Candida genus considerably worsenpost-cancer rehabilitation.

    In patients suffering from locally advanced, unresectable squamous cell carcinoma (SCC) of the base of the tongue, the floor of the mouth, the mobile part of the tongue, the tonsils, the hypopharynx and the larynx radiotherapy yields poor results, due to local failure rather than to distant metastases. Since toxicity of radiotherapy and cytotoxic chemotherapy do not overlap entirely efforts were made to achieve better results combining these two treatment modalities. Clinical trials on simultaneous radiotherapy/chemotherapy focussed on two cytotoxic agents: Cis-dichlorodiammineplatinum(II) (cis-DDP) and 5-flourouracil (5-FU). Another approach to overcome the radioresistance of large SCC adopts accelerated fractionation. The potential tumor doubling time of sqamous cell carcinomas is about four days, and thus repopulation of surviving clonogenic tumor cells during fractionated radiotherapy may be the cause of poor treatment results. In this pilot study a twice daily fractionated split-course radiotherapy is combined with simultaneous administration of cis-DDP and 5-FU with folinic acid (FA) enhancement.

    Breast cancer is the second most common type of cancer in the world, being the most common among women, responsible for 22% of new cases each year. It's surgical and radiation treatment evolved from radical procedures (Halsted radical mastectomy and total external breast radiotherapy) to less radical and more conservative procedures. With the use of modern oncoplastic surgery techniques and accelerated partial breast radiotherapy, selected patients can benefit with better aesthetic results, fewer side effects, and more comfortable and brief treatments.

    The primary results of our phase II randomized trial suggested that compared with conventional preoperative chemoradiation (CRT), the addition of chemotherapy (CT) before CRT and surgery allows most patients receive their planned treatment with a better toxicity profile without compromising the pathological complete response and complete resection rates. We now report the 5-year outcomes. Patients with distal or middle third, T3-T4 and/or N+ rectal adenocarcinoma selected by magnetic resonance imaging, were randomly assigned to arm A-preoperative CRT followed by surgery and four cycles of postoperative adjuvant capecitabine and oxaliplatin (CAPOX)-or arm B-four cycles of CAPOX followed by CRT and surgery. The following 5-year actuarial outcomes were assessed: the cumulative incidence of local relapse (LR) and distant metastases (DM), disease-free (DFS) and overall survival (OS). A total of 108 eligible patients were randomly assigned to arm A (n = 52) or arm B (n = 56). With a median follow-up of 69.5 months, 5-year DFS was 64% in arm A and 62% in arm B (P = 0.85) and 5-year OS was 78% in arm A and 75% in arm B (P = 0.64). The 5-year cumulative incidence of LR was 2% and 5% (P = 0.61) and 5-year cumulative incidence of DM was 21% and 23%; (P = 0.79) in arms A and B, respectively. Both treatment approaches yield similar outcomes. Given the lower acute toxicity and improved compliance with induction CT compared with adjuvant CT, integrating effective systemic therapy before CRT and surgery is a promising strategy and should be examined in phase III trials. © The Author 2015.

    Neo-adjuvant chemoradiotherapy is the gold standard of the treatment of advanced oesophageal squamous cell carcinoma. The role of surgery L. chemoradiotherapy is still debated. Feasibility of curative resection depends on dose of radiotherapy, morbi-mortality rates, and nutrition status at the end of the protocol especially for non-responders patients. Adding surgery to radio-chemotherapy improves local tumour control but does not increase overall survival of patients with advanced oesophageal squamous cell carcinoma. According to the two randomized trials published on the subject, surgery is not recommended after chemoradiotherapy for responders. Recommendations of French National Thesaurus are: exclusive chemoradiotherapy as reference, oesophagectomy for residual tumour as alternative for operable patients. Surgery may be proposed for selected non-responders patients and some complete pathology response in expert center. (author)

  18. Current status and future strategies of cytoreductive surgery plus intraperitoneal hyperthermic chemotherapy for peritoneal carcinomatosis

    Institute of Scientific and Technical Information of China (English)

    2008-01-01

    This article is to offer a concise review on the use of cytoreductive surgery (CRS) plus intraperitoneal hyperthermic chemotherapy (IPHC) for the treatment of peritoneal carcinomatosis (PC). Traditionally, PC was treated with systemic chemotherapy alone with very poor response and a median survival of less than 6 mo. With the establishment of several phase studies, a new trend has been developed toward the use of CRS plus IPHC as a standard method for treating selected patients with PC, in whom sufficient cytoreduction could be achieved. In spite of the need for more high quality phase studies, there is now a consensus among many surgical oncology experts throughout the world about the use of this new treatment strategy as standard care for colorectal cancer patients with PC. This review summarizes the current status and possible progress in future.

    In this work, a procedure, based on Monte Carlo techniques, to analyse the effect on the tumour control probability of the time interval between surgery and postoperative radiotherapy is presented. The approach includes the tumour growth as well as the survival of tumour cells undergoing fractionated radiotherapy. Both processes are described in terms of the binomial distribution. We have considered two different growth models, exponential and Gompertz, the parameters of which have been fixed to reproduce the clinical outcome corresponding to a retrospective study for patients with head and neck squamous cell carcinomas. In the cases analysed, we have not found significant differences between the results obtained for both growth models. The mean doubling times found for residual clonogens after surgery are less than 40 days. The rate of decrease in local control is around 0.09% per day of delay between surgery and radiotherapy and the corresponding time factor is about 0.11 Gy per day.

    Purpose: to determine the maximum tolerated dose (MTD) of gemcitabine every 2 weeks to a concurrent radiotherapy administered during an aggressive program of sequential and simultaneous radio-/chemotherapy for locally advanced, unresectable non-small cell lung cancer (NSCLC). Patients and methods: ten patients with histologically confirmed NSCLC were observed and treated in accordance with a combined radio-/chemotherapy protocol. This included two cycles of induction chemotherapy with gemcitabine (1,200 mg/m{sup 2}) and vinorelbine (30 mg/m{sup 2}) at days 1, 8 and 22, 29, followed by concurrent radiotherapy including [{sup 18}F] fluorodeoxyglucose positron emission tomography-(FDG-PET-) based target volume definition (2.0 Gy/d; total dose 66.0 Gy) and chemotherapy with gemcitabine every 2 weeks at days 43, 57, and 71. The initial dose was 300 mg/m{sup 2}. The dose of gemcitabine was increased by 100 mg/m{sup 2} until the MTD was realized. Three patients were enrolled for each dose level. Results: dose-limiting toxicity (DLT) was identified for the patient group receiving gemcitabine 500 mg/m{sup 2}, due to grade 2 esophagitis (next to grade 3) in all patients. 6 weeks after the completion of radio-/chemotherapy, most patients still presented treatment-induced esophagitis. In accordance with expected complications, such as esophagitis, dysphagia and odynophagia, the MTD was defined at this dose level, although no DLT grade 3 was reached. Conclusion: after induction chemotherapy, the MTD and frequency of gemcitabine in locally advanced NSCLC is 500 mg/m{sup 2} every 2 weeks during a maximum of 7 weeks of thoracic radiotherapy.

    High-dose chemotherapy with autologous bone marrow and/or peripheral blood stem cell (PBSC) support is increasingly employed in the adjuvant treatment of high-risk breast cancer. Subsequent radiotherapy has been reported to be associated with morbidity and mortality resulting from pulmonary toxicity. In addition, the course of radiation therapy may be hampered by excess myelosuppression. The aim of this study was to investigate the contribution to radiation-induced toxicity of a high-dose chemotherapy regimen (CTC) that incorporates cyclophosphamide, thiotepa and carboplatin, in patients with high-risk breast cancer.

    This study reports on T3/T4 base of tongue (BOT) tumors treated at the Erasmus MC (Rotterdam) with external beam radiotherapy (EBRT) and brachytherapy (BT). Local control, survival, and functional outcome are compared to results obtained in similar patients treated at the Vrije University Medical Center (VUMC, Amsterdam) by surgery and postoperative RT (PORT). At Rotterdam 46/2 Gy was given to the primary and bilateral neck, followed by an implant using low-dose-rate (LDR 24-35 Gy; median 27 Gy), or fractionated high-dose-rate (fr. HDR 20-28 Gy; median 24 Gy). A neck dissection (ND) was performed in case of N+ disease. 67% of BOT tumors had a T4 cancer. At Amsterdam surgery (S) followed by PORT 40-70 Gy (median 60 Gy) was performed; 26% BOT tumors were T4. Sex, age and nodal distribution were similar. Actuarial local control and survival were computed. Performance Status Scale (PSS) scores were established. Xerostomis was determined on visual analog scales (VAS). Local failure at 5-years was 37% (Rotterdam) vs. 9% (Amsterdam) (p Rotterdam patients had more advanced BOT tumors (67% vs. 26% T4), explaining the higher local failure rate. Given the organ preservation properties of radiotherapy-only and the better PSS scores, the jury is still out on the optimal treatment for BOT tumors.

    Since there have been few reports on postmastectomy radiotherapy having a high evidence level in Japan, the significance of postoperative radiotherapy and the irradiation techniques were reviewed based on reports from Western countries. Authors focused on the indications for postoperative irradiation, irradiation methods (irradiation sites, irradiation techniques; prosthetics, methods of irradiating the chest wall and lymph nodes, timing of irradiation), and complications, and discuss them. The factors thought to be adaptable to postmastectomy radiotherapy have been listed. Axillary lymph node metastasis and the size of the primary focus are thought to be important factors in locoregional recurrence. The chest wall and the supraclavicular lymph nodes are the usual sites of irradiation after mastectomy. The irradiation method consists of tangential irradiation of the chest wall and single-field irradiation of the supraclavicular lymph nodes, with 46-50 Gy in fractional doses of 1.8-2 Gy x 5/w is administered for 4.5-5.5 weeks. The timing of irradiation in the West is generally after chemotherapy. Adverse radiation effects include ischemic heart disease, pneumonitis, arm edema, rib fractures, and brachial plexus paralysis. The frequency of these complications is increased by the combined use of chemotherapy or surgery. The breast cancer cure rate in Japan is generally better than in the West. It remains to be determined whether the clinical data from Europe and America are applicable to the treatment of breast cancer in Japan. To address this issue, a clinical investigation should be performed in Japan with close cooperation between surgeons, physicians, pathologists, and radiotherapists. (K.H.)

    Objective To investigate and compare the biological characteristics and sensitivity to chemotherapy and radiother-apy of intrahepatic and extrahepatie cholangiocarcinoma cells in vitro.Methods The intrahepatic and extrahepatie eholangiocarcinoma cell lines were established, and cells with steady passage were chosen to study the biological characteristics including morphology, growth dynamics, chromosome, and levels of cancer antigen (CA)125, CA 19-9, alpha-fetoprotein (AFP), and carcino-embryonic antigen (CEA).M.eanwhile, MTT assay was used to determine the sensitivity of both kinds of cells to 6 chemotherapeutic drugs, inclu-ding cisplatin, paclitaxel, harringtonine, 5-fluorouracil, vincristine, and aelacimomycin, and the inhibitory rate of ceils under the irradiation of 10 Gy ray was also measured.Reanlts The intrahepatic cholangiocarcinoma cells were mostly fusiform in shape, and extrahepatic eholangiocar-cinoma cells were mostly round or polygon in shape. Their doubling time was 26. 3 hours and 23.1 hours, respectively.Their average number of chromosomes was 59 (range, 38-84) and 67 (range, 49-103 ), respectively. The chromo-some karyotypes of most intrahepatlc ebolangiocarcinoma cells were hyperdiploid and hypotriploid, while hypertriploid was predominant in extrahepatic cholangioearcinoma cells. The level of CA 125 in supernatant of extrahepatic cholangio-carcinoma cells increased obviously, while levels of other determined tumor markers in both kinds of cells were all with-in normal range. The intrahepatic cholangiocarcinoma cells were low sensitive to cisplatin and paclitaxel, but not sensi-tive to the other 4 chemotherapeutic drugs. The extrahepatic cholangiocarcinoma cells were high sensitive to eisplatin,but not sensitive to the other 5 drugs. Both kinds of cells had poor sensitivity to radiotherapy.Conelusions Intrahepatic and extrahepatie cbolangiocareinoma cells show differences in shape, doubling time,chromosome karyotype, tumor marker level, and

    Full Text Available Background: Cardiovascular damage after Radiotherapy of left chest wall for left breast cancer is a potential fear, therefore studing both the possible causes of radiation-induced heart damage and preventive measures are crucial issues in radiation therapy of breast cancer. The present study investigates noninvasively the possible acute and chronic ECG changes and their incidences after Radiotherapy in patients with left sided breast cancer who have received 6-8 courses of Anthracycline based chemotherapy following mastectomy. Methods: 56 patients with breast cancer (invasive ductal carcinoma who had been undergone modified radical mastectomy, adjuvant Anthracycline based chemotherapy, and left sided chest wall electron therapy with direct field, have been evaluated. All patients investigated with physical examination and standard 12 leads ECG before, and immediately after completion of radiation therapy, and 6 months afterward. Results: New electrocardiographic changes after therapy were seen in 3 patients (5.35% and reduced to 2 cases (3.57% after 6 months. there was no significant difference in T wave findings before and after radiation therapy(P=0.521.Also there wasn’t any correlation between stage of cancer and any changes in ECG findings after radiation therapy (P=0.56. Conclusion: There were no clinical cardiac symptoms or signs after Radiotherapy. Most affected leads in ECG were V1-V4 and the main abnormality was Inverted T wave. This findings suggest that the most acute and chronic electrocardiographic effect of irradiation on heart is repolarization abnormality. This study suggests that there are no significant ECG changes after Radiotherapy of left chest wall by electron beam in patients with left sided breast cancer who has received Anthracycline based chemotherapy following mastectomy. Also Radiotherapy by electron doesn't induce any clinical cardiac symptoms and signs in these patients. Therefore, we recommend

    Blood platelets from patients with cancer (before or after the surgery) exhibit a variety of qualitative abnormalities. Different anti-cancer drugs may also induce the oxidative/nitrative stress in blood platelets and change their hemostatic properties. The aim of our study was to explain the effect of superoxide anion radicals ([Formula: see text]) production on hemostatic properties of blood platelets (activated by a strong physiological agonist - thrombin) from breast cancer patients before the surgery, after the surgery, and after various phases (I-IV) of chemotherapy (doxorubicin and cyclophosphamide). Patients were hospitalized in the Department of Oncological Surgery and at the Department of Chemotherapy, Medical University of Lodz, Poland. We measured the platelet aggregation as the marker of hemostatic activity of blood platelets. We observed an increase of [Formula: see text] in thrombin-activated blood platelets from patients with breast cancer (before or after the surgery and after various phases of the chemotherapy) compared to the healthy group. Our other experiments demonstrated that aggregation (induced by thrombin) of blood platelets from patients with breast cancer before the surgery, after the surgery, and after various phases of the chemotherapy differs from aggregation of platelets obtained from healthy volunteers. Moreover, our results showed the correlation between the [Formula: see text] generation and changes of platelet aggregation in breast cancer patients before the surgery, after the surgery, and after the chemotherapy (I and IV phases). Considering the data presented in this study, we suggest that the production of [Formula: see text] in blood platelets (activated by thrombin) obtained from breast cancer patients may induce the changes of platelet aggregation, which may contribute in thrombosis in these patients.

    Acute lymphoblastic leukemia has a higher mortality rate in boys as a result of possible testicular involvement; indeed, the testicle is the site of initial relapse in 6% of cases and is involved in 15% of all cases. Clinical diagnosis of testicular involvement is usually readily established. Treatment is delivery of 24 grays to both testicles and intensification of chemotherapy. In children who recover from their leukemia, this irradiation produces not only destruction of germ cells but also endocrine impairment which should be looked for and treated; replacement therapy with slow-action testosterone will be combined with the other hormonal treatments which pituitary deficiencies secondary to cranial irradiation may require.

    , sex, lung function, and comorbidity were all associated with survival. Apart from excess mortality among patients with unspecified histological subtypes (hazard ratio), there was no clear difference between the specified subtypes. When adjusting for the other factors, particularly age, sex......, performance status, and stage proved to be robust while risk estimates for comorbidity were attenuated somewhat. When grouped by the three types of cancer treatment or no treatment, there was no influence of comorbidity on radiation therapy and modest influence on survival after chemotherapy...

    For children with stage II testicular malignant germ cell tumors (MGCT), the survival is good with surgery and adjuvant chemotherapy. However, there is limited data on surgical results for cases in which there was no imaging or pathologic evidence of residual tumor, but in which serum tumor markers either increased or failed to normalize after an appropriate period of half-life time post-surgery. To determine the use of chemotherapy for children with stage II germ cel tumors, we analyzed the outcomes (relapse rate and overall survival) of patients who were treated at the Sun Yat-sen University Cancer Center between January 1990 and May 2013. Twenty-four pediatric patients with a median age of 20 months (range, 4 months to 17 years) were enrol ed in this study. In 20 cases (83.3%), the tumors had yolk sac histology. For definitive treatment, 21 patients underwent surgery alone, and 3 patients received surgery and adjuvant chemotherapy. No relapse was observed in the 3 patients who received adjuvant chemotherapy, whereas relapse occurred in 16 of the 21 patients (76.2%) treated with surgery alone. There were a total of 2 deaths. Treatment was stopped for 1 patient, who died 3 months later due to the tumor. The other patient achieved complete response after salvage treatment, but developed lung and pelvic metastases 7 months later and died of the tumor after stopping treatment. For children treated with surgery alone and surgery combined with adjuvant chemotherapy, the 3-year event-free survival rates were 23.8% and 100%, respectively (P=0.042), and the 3-year overal survival rates were 90.5%and 100%, respectively (P=0.588). These results suggest that adjuvant chemotherapy can help to reduce the recurrence rate and increase the survival rate for patients with stage II germ cel tumors.

    To investigate treatment outcome and long term complication after surgery and radiotherapy (RT) for pituitary adenoma. From 1990 to 2009, 73 patients with surgery and RT for pituitary adenoma were analyzed in this study. Median age was 51 years (range, 25 to 71 years). Median tumor size was 3 cm (range, 1 to 5 cm) with suprasellar (n = 21), cavernous sinus extension (n = 14) or both (n = 5). Hormone secreting tumor was diagnosed in 29 patients; 16 patients with prolactin, 12 patients with growth hormone, and 1 patient with adrenocorticotrophic hormone. Impairment of visual acuity or visual field was presented in 33 patients at first diagnosis. Most patients (n = 64) received RT as postoperative adjuvant setting. Median RT dose was 45 Gy (range, 45 to 59.4 Gy). Median follow-up duration was 8 years (range, 3 to 22 years). In secreting tumors, hormone normalization rate was 55% (16 of 29 patients). For 25 patients with evaluable visual field and visual acuity test, 21 patients (84%) showed improvement of visual disturbance after treatment. The 10-year tumor control rate for non-secreting and secreting adenoma was 100% and 58%, respectively (p < 0.001). Progression free survival rate at 10 years was 98%. Only 1 patient experienced endocrinological recurrence. Following surgery, 60% (n = 44) suffered from pituitary function deficit. Late complication associated with RT was only 1 patient, who developed cataract. Surgery and RT are very effective and safe in hormonal and tumor growth control for secreting and non-secreting pituitary adenoma.

    Objective: to determine whether low-level laser therapy can prevent salivary hypofunction after radiotherapy and chemotherapy in head and neck cancer patients. Materials and methods: ee evaluated 23 head and neck cancer patients, of whom 13 received laser therapy and 10 received clinical care only. An InGaAlP laser was used intra-orally (at 660 nm and 40 mW) at a mean dose of 10.0 J/cm{sup 2} and extra-orally (at 780 nm and 15 mW) at a mean dose of 3.7 J/cm{sup 2} , three times per week, on alternate days. Stimulated and unstimulated sialometry tests were performed before the first radiotherapy and chemotherapy sessions (NO) and at 30 days after the end of treatment (N30). Results: At N30, the mean salivary flow rates were significantly higher among the laser therapy patients than among the patients who received clinical care only, in the stimulated and unstimulated sialometry tests (p = 0.0131 and p = 0.0143, respectively). Conclusion: low-level laser therapy, administered concomitantly with radiotherapy and chemotherapy, appears to mitigate treatment induced salivary hypofunction in patients with head and neck cancer.

Stimulated and unstimulated sialometry tests were performed before the first radiotherapy and chemotherapy sessions (N0) and at 30 days after the end of treatment (N30). At N30, the mean salivary flow rates were significantly higher among the laser therapy patients than among the patients who received clinical care only, in the stimulated and unstimulated sialometry tests (p = 0.0131 and p = 0.0143, respectively). Low-level laser therapy, administered concomitantly with radiotherapy and chemotherapy, appears to mitigate treatment-induced salivary hypofunction in patients with head and neck cancer.

    Purpose: To retrospectively analyze the outcomes, toxicity, quality of life, and voice quality of patients with T3 laryngeal cancer treated with radiotherapy and to identify subgroups of patients in whom the addition of chemotherapy to radiotherapy is necessary. Methods and Materials: Between March 1996 and November 2009, 170 consecutive patients with T3 tumor were treated with (chemo)radiotherapy. Endpoints of the study were local control (LC), locoregional control (LRC), disease-free survival (DFS), overall survival (OS), late toxicity, quality of life, and voice handicap index. Results: After a median follow-up time of 32 months (range, 7-172), the 3-year actuarial rates of LC, LRC, DFS, and OS were 73%, 70%, 64%, and 61%, respectively, and the 5-year figures were 68%, 65%, 60%, and 49%, respectively. At last follow-up, 84 patients (49.5%) were still alive, 65 of them (77.3%) without local progression. Laryngectomy was performed in 16 patients, leaving 49 patients with anatomic organ preservation, corresponding to an actuarial laryngectomy-free survival of 58.3% at 3 years. The figures for patients treated with chemoradiotherapy and radiotherapy alone were 76.8% and 53.5%, respectively (p = 0.001). Chemoradiotherapy was the only significant predictor for LC on multivariate analysis. The overall 5-year cumulative incidence of late Grade {>=}2 toxicity was 28.2%. Chemoradiotherapy, compared with radiotherapy alone, resulted in slight increase in late toxicity and slight deterioration of quality of life and voice-handicap-index scores. However, the differences were statistically not significant. Conclusion: The addition of chemotherapy to radiotherapy in T3 laryngeal cancer significantly improved LC and laryngectomy-free survival without statistically significant increases in late toxicity or deterioration of quality of life or voice handicap index.

    From 1985 through 1990, twelve patients with estehesioneuroblastoma have been treated at the Department of Radiotherapy at the University of Erlangen. Two had Kadish stage A, one stage B, and nine stage C. There were seven males and five females with a mean age of 43 years. Eleven patients had combined trancranial-transbasal surgery prior to radiotherapy (five R0-, four R1-, and two patients R2-resections) and one received radiotherapy only. The dose was 12 to 60 Gy (mean 54 Gy) in 1.8 Gy to 2 Gy per fraction. 8/12 patients (67%) were locally controlled. One had progressive disease during radiotherapy after partial resection and died. Three had local recurrences, one in-field and two marginal. One patient with a local recurrence developed cervical lymph node metastases, and one locally controlled patient developed bone metastases but is alive eight years after chemotherapy plus radiotherapy for metastatic disease. The five-year-overall and recurrence-free survival was 72% and 55%, respectively. (orig./MG)

    Background. To investigate the patterns of relapse following intensity modulated radiotherapy (IMRT) given after radical surgery for oral and oropharyngeal squamous cell cancer. Patients and methods. One hundred and two patients with oral or oropharyngeal cancer were treated with radical surgery followed by IMRT up to a mean total dose of 60 Gy between years 2001 and 2007. Thirty-nine of the patients (%) also received concomitant weekly cisplatin. Forty of the patients had oral and 62 had oropharyngeal cancer. Data on the tumour, patient and treatment factors were collected. Following therapy the patients were followed by clinical examination, endoscopy and MRI/CT at 2- to 3-months interval up to 2 years and thereafter at 6-month intervals. Results. The mean follow-up time of the patients was 55 months (range, 26-106 months). The rate for local tumour control for the whole cohort was 92.2%: 87.5% for oral cancer patients and 96.7% for oropharyngeal cancer patients. The 5-year disease specific survival was 90.2% and 5-year overall survival 84.3%. During the follow-up eight locoregional recurrences were observed, three at the primary tumour site and one at regional nodal site and four at both sites. The mean time to primary tumour recurrence was seven months (range, 2-10 months) and to nodal recurrence seven months (range, 2-12 months). Distant metastasis occurred in six (6%) patients. The factors associated with poor prognosis were the primary tumour size and tumour site with oral cancers having worse outcome. The treatment was well tolerated with no unexpected toxicities. The most frequent late toxicity was dysphagia necessitating permanent PEG in five patients. This was correlated with the advanced primary tumour size and resulting in wide tumour excision and reconstruction. Conclusions. Surgery combined with postoperative radiotherapy given as IMRT results in low level of tumour recurrence

    Full Text Available Introduction. Cytoreductive surgery (CS with hyperthermic intraperitoneal chemotherapy (HIPEC is a new approach for peritoneal carcinomatosis. However, high rates of complications are associated with CS and HIPEC due to treatment complexity; that is why some patients need stabilization and surveillance for complications in the intensive care unit. Objective. This study analyzed that ICU stay is necessary after HIPEC. Methods. 39 patients with peritoneal carcinomatosis were treated according to strict selection criteria with CS and HIPEC, with closed technique, and the chemotherapy administered were cisplatin 25 mg/m2/L and mitomycin C 3.3 mg/m2/L for 90-minutes at 40.5°C. Results. 26 (67% of the 39 patients were transferred to the ICU. Major postoperative complications were seen in 14/26 patients (53%. The mean time on surgical procedures was 7.06 hours (range 5−9 hours. The mean blood loss was 939 ml (range 100–3700 ml. The mean time stay in the ICU was 2.7 days. Conclusion. CS with HIPEC for the treatment of PC results in low mortality and high morbidity. Therefore, ICU stay directly following HIPEC should not be standardized, but should preferably be based on the extent or resections performed and individual patient characteristics and risk factors. Late complications were comparable to those reported after large abdominal surgery without HIPEC.

    We describe a case of a 62-year-old male with an epithelioid MPNST of the left foot. Multiple lung metastases developed after radical surgery on the primary lesion. The response to adjuvant chemotherapy including doxorubicin and ifosfamide was favorable, and thoracoscopic resection was subsequently performed on the remaining three metastases. No evidence of recurrence or metastasis was observed at the 12-month followup after the first operation. Further followup and chemotherapy may be required.

    Outcomes of radiotherapy (RT) compared with chemotherapy (CT) remain poorly defined for clinical stage (CS) IIA and IIB seminoma. We aimed to evaluate the current role of the two treatment modalities in this setting of testicular seminoma. A systematic review and meta-analysis (MA) was carried out to identify all evaluable studies. Search was limited to studies published after 1990 and included the Medline, Embase databases, and abstracts from ASCO (GU), ESMO, AUA, and ASTRO meetings up to April 2014. Sensitivity analyses were applied including the following: CSIIA and CSIIB, paraortic + iliac RT only in both stages, RT dose (≥30 versus seminoma, a trend in favor of CT for a lower incidence of side-effects and RR in CSIIB was found. This evidence is limited by the retrospective quality of studies and their small sample size. © The Author 2014.

    In order to investigate time course of effects of chemotherapy and radiotherapy on pancreatic cancer, we used the monolayer culture of a human pancreatic cancer cell line, SUIT-2 which produces CEA and CA19-9. Into the culture various kinds of anti-cancer drugs (MMC, ADR, FAR, 5FU, FT, CDDP, CPT-11) were administered for a period of 2 days, followed by irradiation with {sup 60}Co. Observation period was 20 days, during which we measured LDH, CEA and Ca19-9 in medium, DNA, protein, CEA and CA19-9 in cells in addition to observation of cells through microscope. Effects of anti-cancer drugs on pancreatic cancer cells were greater than those of irradiation when doses of anti-cancer drugs were enough. By using a lot of anti-cancer drugs, LDH value in medium increased at early time and decreased later. CEA and Ca19-9 values in medium decreased with the lapse of time, while they were increased later when small doses of the drugs had been administered. DNA, protein, CEA and Ca19-9 values in cells showed a decrease in accordance with increased doses of the drugs. Effects of FT and CPT-11 were marginal compared with the other drugs. (author).

    Adjuvant radiotherapy after surgery or exclusive radiotherapy, with or without concurrent chemotherapy is a valuable treatment option in the great majority of patients with head and neck cancer. Recent technical progress in radiotherapy has resulted in a decreased incidence of xerostomia. Another common toxicity of radiotherapy is dysphagia, which alters the nutritional status and quality of life of patients in remission. The objective of this review is to describe the physiology of swallowing function, the pathophysiology of radiation-induced dysphagia and the various strategies currently available to prevent this complication.

    The aim of this study was to investigate the therapeutic response and toxicity of intensity-modulated radiation therapy (IMRT) or conventional radiotherapy (c-RT) as adjuvant therapy in patients with pelvic locoregional recurrence of cervical cancer after radical surgery. This retrospective study included 161 patients with unresectable pelvic locoregional recurrence of cervical cancer after radical surgery between March 2003 and May 2012. All patients were initially diagnosed with International Federation of Gynecology and Obstetrics stage IB-IIA cervical cancer and received radical hysterectomy and pelvic lymphadenectomy. A total of 82 patients were treated with c-RT, whereas the remaining 79 patients underwent IMRT. Intracavitary brachytherapy and concurrent chemotherapy were performed during external irradiation. The mean dose delivered to the planning target volume was significantly higher in the IMRT group than in the c-RT group (61.8 vs 50.3 Gy, P = 0.029). Intensity-modulated radiation therapy plans yielded better dose sparing of small bowel, bladder, and rectum than did c-RT (P cervical cancer after radical surgery. The acute and chronic toxicities were acceptable, and the adjacent organs at risk were well protected.

    It is clear that the risk of toxicity to normal tissues in combined therapy is reduced by separating drug administration and radiation exposure in time. The short-term interaction of drugs and radiation aimed at producing enhanced tumour cell kill is difficult to demonstrate in vivo in animal experiments and unlikely to be important in clinical practice. Increased toxicity of normal tissues in man has been manifest both in terms of early and late reactions and probably also in carcinogenesis. In the latter context choice of drug and possibly sequencing may be important in minimising the risk of tumour induction. There are few experimental studies examining moderately long time intervals between drug and radiation exposure. The administration of chemotherapy prior to irradiation may be less toxic than the converse sequence, although clinical data supporting this contention are limited at the present time.

    Diffuse malignant peritoneal mesothelioma is a rare and lethal disease. Locoregional treatments combining cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (HIPEC) seem to improve prognosis. Cytoreductive surgery and HIPEC was performed in 22 patients at the Centre Hospitalier-Lyon Sud between 1989 and 2006. A retrospective analysis of survival was carried out to assess clinical and histological prognostic factors. Nineteen patients with diffuse malignant peritoneal mesothelioma were included (16 epithelial, 3 biphasic and 3 multicystic forms). Sixteen patients presented stage 3 or 4 peritoneal mesothelioma according to the Gilly classification. Optimal cytoreductive surgery was performed for 11 patients (complete macroscopic resection or residual tumor nodules less than 2.5mm). No post-operative deaths occurred but 9 patients (47%) presented grade III or IV post-operative complications. The overall median survival was 36.9 months; completeness of cytoreduction was the only significant prognostic factor. Cytoreductive surgery combined with HIPEC may improve the length of survival for patients with diffuse malignant peritoneal mesothelioma; such patients should be treated in specialized centers.

    Carbon ion radiotherapy (CIRT) has been expected to be an alternative for surgery for early-stage non-small-cell lung cancer (NSCLC) and adopted as the second-best choice even in operable patients although local recurrence after CIRT is sometimes experienced. The purpose of this study was to investigate the demographic data, perioperative courses and therapeutic outcomes of patients who underwent salvage resection for local recurrence after CIRT. From November 1994 to February 2012, CIRT was applied for 602 c-T1/T2/T3N0M0 NSCLC lesions of 599 patients at the National Institute of Radiological Science. A total of 95 (16%) patients were diagnosed as having local recurrence, of whom 12 underwent salvage surgeries. The medical records were retrospectively reviewed. There were 7 men and 5 women (mean age, 63 ± 7.4 years). The clinical stages upon initial presentation with NSCLC were as follows: 4 IA, 7 IB and 1 IIB. All the patients were operable, but refused surgery and underwent CIRT. The median progression-free survival time after CIRT was 20 months (range, 7.1-77 months), and salvage surgery was performed at a median of 24 months (range, 9-78 months) after CIRT. All surgeries were successfully performed without any significant CIRT-related adhesions during the surgery, resulting in no mortality or Clavien-Dindo grade 3-4 postoperative complications. However, the distribution of pathological stages was as follows: 4 IA, 3 IB, 2 IIB, 2 IIIA and 1 IV, which included 6 upstages from the clinical stages before CIRT. The Kaplan-Meier estimate of overall survival after the salvage surgery showed that the 3-year survival rate was 82%. The dose intensity of CIRT spared the hilum of the lungs and parietal pleura, none of the patients developed adhesions outside of the radiation field, such that the salvage surgeries for local recurrence after CIRT were safe and feasible. © The Author 2015.

    In recent years, several cytoprotective agents have been developed o protect normal cells form the toxic effects of chemotherapy and radiotherapy. The ideal cytoprotectant agent would be that one able to allow the intensification of chemotherapy's dose.; to protect largest number of normal tissues and organs when used with a variety of chemotherapy agents; to confer specific protection for normal tissues; to preserve anti tumor effect and to have little and/or manageable toxicity and side effects. Amifostine fits in on these questions also presenting a broad spectrum of action. This paper aims the discussion of the use of cryoprotective amifostine, their main characteristics/functions, adverse effects, action mechanism, administration and recommended dosage. (author)

    The objective of the study was to evaluate the effect of neoadjuvant chemotherapy on the survival of patients with oropharyngeal cancer. Patients with a squamous cell carcinoma of the oropharynx for whom curative radiotherapy or surgery was considered feasible were entered in a multicentric randomized trial comparing neoadjuvant chemotherapy followed by loco-regional treatment to the same loco-regional treatment without chemotherapy. The loco-regional treatment consisted either of surgery plus radiotherapy or of radiotherapy alone. Three cycles of chemotherapy consisting of Cisplatin (100 mg/m2) on day 1 followed by a 24-hour i.v. infusion of fluorouracil (1000 mg/m2/day) for 5 days were delivered every 21 days. 2–3 weeks after the end of chemotherapy, local treatment was performed. The trial was conducted by the Groupe d'Etude des Tumeurs de la Tête Et du Cou (GETTEC). A total of 318 patients were enrolled in the study between 1986 and 1992. Overall survival was significantly better (P = 0.03) in the neoadjuvant chemotherapy group than in the control group, with a median survival of 5.1 years versus 3.3 years in the no chemotherapy group. The effect of neoadjuvant chemotherapy on event-free survival was smaller and of borderline significance (P = 0.11). Stratification of the results on the type of local treatment, surgery plus radiotherapy or radiotherapy alone, did not reveal any heterogeneity in the effect of chemotherapy. © 2000 Cancer Research Campaign http://www.bjcancer.com PMID:11189100

    Full Text Available Abstract Background A variety of hypofractionated radiotherapy schedules has been proposed after breast conserving surgery in the attempt to shorten the overall treatment time. The aim of the present study is to assess acute and late toxicity of using daily fractionation of 2.25 Gy to a total dose of 45 Gy to the whole breast in a mono-institutional series. Methods Eighty-five women with early breast cancer were assigned to receive 45 Gy followed by a boost to the tumour bed. Early and late toxicity were scored according to the Radiation Therapy Oncology Group criteria. For comparison, a group of 70 patients with similar characteristics and treated with conventional fractionation of 2 Gy to a total dose of 50 Gy in 25 fractions followed by a boost, was retrospectively selected. Results Overall median treatment duration was 29 days for hypofractionated radiotherapy and 37 days for conventional radiotherapy. Early reactions were observed in 72/85 (85% patients treated with hypofractionation and in 67/70 (96% patients treated with conventional fractionation (p = 0.01. Late toxicity was observed in 8 patients (10% in the hypofractionation group and in 10 patients (15% in the conventional fractionation group, respectively (p = 0.4. Conclusions The hypofractionated schedule delivering 45 Gy in 20 fractions shortened the overall treatment time by 1 week with a reduction of skin acute toxicity and no increase of late effects compared to the conventional fractionation. Our results support the implementation of hypofractionated schedules in clinical practice.

Results: Hearing losses were predominately of sensorineural type and mild. Patients who received concomitant CT+RT experienced greater sensorineural hearing loss compared with patients treated with RT alone. A paired sample t-test was conducted to compare the hearing losses before therapy and 6 and 12 months after therapy and was found to be significant ( P < 0.05. It was found that hearing loss was persistent. Significant difference was found in the proportion of hearing loss after RT and RT+CT ( P < 0.05 after 1 month. In addition, mixed hearing loss occurred due to damage to the middle ear contents and can be improved if intervened appropriately.

    The authors report a randomized phase II trial which aimed at comparing over three months the laryngeal protection after a TPF-based induction chemotherapy followed by radiotherapy in combination with cisplatin or cetuximab. Over two years, 153 patients have been concerned. The TPF-based induction chemotherapy followed by radiotherapy with cetuximab seems to be the less toxic. A longer monitoring is needed to get better information in terms of laryngeal protection rate, life quality, and laryngeal functionality. Short communication

    The association between metabolism and cancer has been recently emphasized. This study aimed to find the prognostic significance of obesity in advanced stage rectal cancer patients treated with surgery and radiotherapy (RT). We retrospectively reviewed the medical records of 111 patients who were treated with combined surgery and RT for clinical stage 2–3 (T3 or N+) rectal cancer between 2008 and 2014. The prognostic significance of obesity (body mass index [BMI] ≥25 kg/m{sup 2}) in local control was evaluated. The median follow-up was 31.2 months (range, 4.1 to 85.7 months). Twenty-five patients (22.5%) were classified as obese. Treatment failure occurred in 33 patients (29.7%), including local failures in 13 patients (11.7%), regional lymph node failures in 5, and distant metastases in 24. The 3-year local control, recurrence-free survival, and overall survival rates were 88.7%, 73.6%, and 87.7%, respectively. Obesity (n = 25) significantly reduced the local control rate (p = 0.045; 3-year local control, 76.2%), especially in women (n = 37, p = 0.021). Segregation of local control was best achieved by BMI of 25.6 kg/m{sup 2} as a cutoff value. Obese rectal cancer patients showed poor local control after combined surgery and RT. More effective local treatment strategies for obese patients are warranted.

    Intraoperative radiotherapy (IORT) is a relatively new technique in which irradiation with electrons is performed during an open surgery procedure. This approach poses significant problems in obtaining accurate dosimetry, since neither the pre- nor the postoperative patient images actually matches the irradiation field. Our objective was to implement a software tool able to provide an estimate of the dose distribution, overcoming the problem of the geometrical mismatch between the images and the surgical field during the irradiation. The program was developed in the C programming language, on a noncommercial version of a Philips EasyVision workstation. The application allows to create a new data set by manipulating the preoperative computed tomography and magnetic resonance images in order to simulate the final geometry of the surgical area during the IORT procedure. The exact dose distribution can then be calculated by transferring these new images to a standard radiotherapy planning system. Also an approximate dose distribution can be quickly displayed by superimposing isodose curves obtained from a water phantom. The proposed approach introduces a helpful tool for dosimetry and planning in IORT protocols, improving their accuracy and safety and allowing for more objective quality control and patient follow-up.

    Adjuvant radiotherapy and chemotherapy for breast cancer have been related to transient ischemic attacks and stroke. To date, no studies have investigated the relationship between these adjuvant therapies and subclinical cerebral small-vessel disease in survivors of breast cancer. We compared white matter lesion (WML) volume and prevalence of brain infarctions and cerebral microbleeds (CMBs) between breast cancer survivors exposed to adjuvant radiotherapy and chemotherapy (aRCeBCSs) for primary disease and a population-based reference group. Multimodal magnetic resonance imaging (1.5 T) was performed in 187 aRCeBCSs who received primary breast cancer treatment on average more than 20 years before this study and 374 age-matched reference women without a history of cancer. WML volume was segmented using fully automated software. Experienced raters reviewed all scans for cortical infarctions, lacunar infarctions, strictly lobar CMBs, and deep/infratentorial CMBs with or without lobar CMBs. Within the aRCeBCS group, we also analyzed the association between relative radiotherapy exposure to the carotid artery and prevalence of WML volume and CMBs. The aRCeBCS group had a higher prevalence of both total CMBs and CMBs in a deep/infratentorial region than the reference group. No between-group differences were observed in the prevalence of infarctions or WML volume. Exposure of the carotid artery to radiation was not associated with WML volume or CMBs. More CMBs were found in the aRCeBCS group than in the population-based controls. These vascular lesions potentially mark cerebrovascular frailty that could partially explain the well-documented association between chemotherapy and cognitive dysfunction. No support was found for a radiotherapy-related origin of CMBs. © 2015 by American Society of Clinical Oncology.

    We began performing breast-conserving surgery (BCS) in 1986 to achieve complete resection of breast cancer and omit postoperative radiotherapy (RT) if serial and detailed pathologic examination of the resected specimen within a 5-mm width showed that the of margin was cancer free. At of the end of 1998, 1,233 sides of the breast had been conserved, of which 827 sides were shown to have cancer-free margins. As of the end of 2001, with a mean observation period of 79 months, ipsilateral breast tumor recurrence was recognized on 46 sides (19 recurrences, 27 multiple cancers), for a recurrence rate 5.6% and an annual recurrence rate of 0.85%. This rate is slightly better than those reported by eminent institutions in the USA and Europe which all perform RT, confirming the accuracy and safety of our BCS.

    Background There is little information on the impact of intra-operative systemic chemotherapy on gastric cancer.The aim of this study was to identify prognostic factors in patients with locally advanced gastric cancer and undergoing curative resection,with a focus on evaluating survival benefits and tolerance of intra-operative systemic chemotherapy.Methods We retrospectively analyzed clinicopathological data for 264 consecutive patients who underwent curative resection for gastric cancer at Peking Union Medical College Hospital from January 2002 to January 2007.Survival curves were plotted using the Kaplan-Meier method and compared using log-rank tests.Univariate and multivariate analyses were performed with the Cox proportional hazard model.Results Patients who received intra-operative systemic chemotherapy had higher 5-year overall survival and 5-year disease-free survival rates (P=0.019 and 0.010,respectively) than patients who did not receive intra-operative systemic chemotherapy.In the subgroup analysis,systemic intra-operative chemotherapy benefited the 5-year overall survival and disease-free survival rates for patients with cancer of stage pTNM ⅠB-ⅢB,but not stage pTNM ⅢC.Patients who received intra-operative systemic chemotherapy in combination with post-operative chemotherapy had higher 5-year overall survival and 5-year disease-free survival rates (P=0.046 and 0.021,respectively) than patients who only received postoperative chemotherapy.However,the difference in these rates between patients who received only intra-operative systemic chemotherapy and patients who only received curative surgery was not statistically significant (P=0.150 and 0.170,respectively).Multivariate analyses showed that intra-operative systemic chemotherapy was a favorable prognostic factor for the overall survival and disease-free survival rates (P =0.048 and 0.023,respectively).No grade 4 toxicities related to intra-operative systemic chemotherapy were recorded within the

    Purpose: To report the efficacy and toxicity of radio(chemo)therapy (RCT) in the management of squamous cell anal carcinoma (SQ-AC) and to evaluate the prognostic factors influencing the outcomes. Patients and methods: A consecutive cohort of 138 patients with cT1-4, cN0-3, cM0 SQ-AC were treated with RCT between 1988 and 2011 at our department. Median follow-up time for surviving patients from the start of RCT was 98 months (range, 1-236 months). Patients were treated with a median radiation dose of 56 Gy (range, 4-61 Gy). Concurrent chemotherapy was administered to 119 patients (86%). Results: The survival rates at 2, 5, and 10 years were 88 {+-} 3, 82 {+-} 4, and 59 {+-} 6%, respectively, with a median overall survival (OS) of 167 months. The cumulative incidence for local recurrence at 2 and 5 years was 8 {+-} 2 and 11 {+-} 3%, respectively. The median disease-free survival (DFS) and colostomy-free survival (CFS) times were 132 and 135 months, respectively. In 19 patients (14%), a distant metastasis was diagnosed after a median time of 19 months. In the multivariate analysis, UICC (International Union Against Cancer) stage I-II, female gender, Eastern Cooperative Oncology Group (ECOG) performance status of 0-1, and good/moderate histologic differentiation (G1-2) were significantly associated with a better OS, DFS, and CFS. Conformal radiotherapy planning techniques were significantly associated with a lower cumulative incidence of local recurrence (11 {+-} 3% vs. 38 {+-} 19% at 5 years, p = 0.006). A higher radiation dose beyond 54 Gy was not associated with an improvement in outcome, neither for smaller - (T1/T2) nor for larger tumors (T3/T4). Conclusion: RCT leads to excellent outcomes - especially in patients with stage I/II and G1/G2 tumors - with acceptable toxicity. The probable advantages of high-dose radiotherapy should be considered carefully against the risk of a higher rate of toxicity. Future studies are needed to investigate the role of a more

    Concomitant use of temozolomide (TMZ) and radiotherapy, which is the standard therapy for patients with high-grade glioma, involves a unique regimen with multiple-day, long-term administration. In a previous study, we showed not only higher incidence rates of chemotherapy-induced nausea and vomiting (CINV) during the overall study period, but also substantially higher incidence rates of moderate/severe nausea and particularly severe appetite suppression during the late phase of the treatment. Here, we prospectively evaluated the efficacy of a combination of palonosetron, aprepitant, and dexamethasone for CINV in patients treated with concomitant TMZ and radiotherapy. Twenty-one consecutive patients with newly diagnosed high-grade glioma were enrolled. CINV was recorded using a daily diary and included nausea assessment, emetic episodes, degree of appetite suppression, and use of antiemetic medication. The percentage of patients with a complete response in the overall period was 76.2%. The percentages of patients with no moderate/severe nausea were 90.5, 100, and 90.5% in the early phase, late phase, and overall period, respectively. Severe appetite suppression throughout the overall period completely disappeared. The combination of palonosetron, aprepitant, and dexamethasone was highly effective and well tolerated in patients treated with concomitant TMZ and radiotherapy. This combination of antiemetic therapy focused on delayed as well as acute CINV and may have the potential to overcome CINV associated with a multiple-day, long-term chemotherapy regimen.

    Purpose: To evaluate the outcomes of patients with idiopathic sclerosing orbital inflammation (ISOI) treated with radiotherapy with or without surgery. Methods and Materials: We retrospectively reviewed 22 patients with histopathologically confirmed ISOI who had been refractory or intolerant to steroid therapy and treated with radiation with or without surgery. The radiation dose ranged from 20 to 40 Gy (median, 20 Gy) at 2 Gy per fraction. Presenting signs and treatment outcomes were assessed. Results: Proptosis was the most common sign at presentation, seen in 19 (86.3%) patients, followed by restriction of extraocular movements in 10 (45.4%) patients. Response to radiotherapy was complete in 15 (68.1%) patients, partial in 3 (13.6%) patients, and none in 4 (18.2%) patients. At the median follow-up of 34 months, 14 (63.6%) patients had progression-free state of symptoms and signs, with the progression-free duration ranging from 3 to 75 months (median, 41.5 months), whereas 8 (36.4%) patients had recurrent or persistent disease although they had received radiotherapy. Of the 14 progression-free patients, 6 underwent a bimodality treatment of debulking surgery of ocular disease and radiotherapy. They had had no recurrent disease. Cataract was the most common late complications, and 2 patients experienced a Grade 3 cataract. Conclusion: Our study suggests that for patients with ISOI who are refractory or intolerant to steroid therapy, 20 Gy of radiotherapy appears to be effective for the control of disease with acceptable complications, especially when it is combined with surgery.

    OBJECTIVE To study the local recurrence and the role of whole breast radiotherapy for early breast cancer treated by conservative surgery.METHODS From April 1990 to December 2000, 49 patients with early primary breast cancer were treated by conservative surgery in our hospital. The cases were comprised of Stage 0, 1; Stage Ⅰ, 31; and Stage Ⅱa,17. Forty cases underwent quadrantectomy plus axillary lymph node dissection, and the other 9 cases had lumpectomy alone. Irradiation, which was received by 39 patients, was administered by using low tangential half fields with 6 MV X-ray to decrease the pulmonary irradiative volume.The dose to the whole breast was 45 Gy/22~23f/4.5W, then a 15 Gy boost dose was delivered to the tumor bed by an electron beam. The other patients underwent an irradiated regional field according to postoperative pathology.RESULTS All patients were followed-up for 10 years or more. The 10year local recurrence rates, distant metastasis rates and survival rates were 6.1%, 4.1% and 98.0% respectively. All of the 3 patients who had a local recurrence had infiltrative carcinomas and negative lymph nodes.The 10-year local recurrence rate was higher (2.6% vs. 20.0%) with nonpostoperative whole breast radiotherapy, but the statistical difference was not marked because of the low number of cases. All of the recurrent lesions localized within 3 cm of the primary lesion.CONCLUSION Original recurrence of the tumor was the main type of local recurrence. Radiotherapy after conservative surgery is very essential.After conservative surgery it is feasible that irradiation can be delivered alone to the neighboring region of the tumor bed. Partial breast radiotherapy can substitute for whole breast radiotherapy.

    Purpose. Retrospective analysis of ten cases of germinoma of the central nervous system treated in Pitie Salpetriere Hospital, Paris. Patients and methods- - Ten male patients were treated from 1997 to 2005 for histologically verified primary seminoma of the central nervous system. The median age was 27 years (range 18 0 years). Our option for the treatment was the association of 3 cycles of neo-adjuvant chemotherapy (cisplatin and etoposide) to radiotherapy. Five patients received a craniospinal radiotherapy of 30 Gy (for one patient 36 Gy) followed by a tumoral boost from 20 to 24 Gy. For five patients, irradiated volume was limited to the tumour, total dose from 24 to 54 Gy (for three patients the total dose was from 24 to 30 Gy). Surgery was used for five patients, but only in one case was macroscopic complete. Results. Six patients were in situation of complete remission after neo-adjuvant chemotherapy. All the patients were in situation of complete remission after the irradiation. All the patients were alive free of disease with a median follow-up 46 months (range 13 0 months). Conclusion. In spite of the fact that the intracranial germinal tumours are not the subject of a consensual treatment strategy, this retrospective analysis pleads in favour of chemotherapy followed by limited dose and volume irradiation.

    During the period from 1983 through 1987, a total of 177 children with biopsy proven Hodgkin's disease have undergone chemotherapy combined with local irradiation. The patients were divided into low, middle, and high stage groups. MVPP chemotherapy, consisting of mechlorethamine, vinblastine, procarbazine, and prednisone, was given as the basic treatment. B-DOPA chemotherapy, consisting of bleomycin, dacarbazine, vincristine, prednisone, and adriamycin, was given to some children. Irradiation was limited to involved regions by cobalt therapy for 114 patients and by conventional radiotherapy for 56 patients. In the remaining 7 patients, radiotherapy was given to peripheral lymph nodes and cobalt therapy to mediastinal tumor and/or abdomen. Irradiation doses ranged from 30 to 40 Gy in most of the patients. One hundred and seventy five patients (98.9%) had complete remission (CR). The probability for 5-year disease-free survival and survival was 0.91 and 0.98, respectively. The most common hematological complication was leukopenia. Relapse occurred in a total of 15 patients (8.5%) within 4-48 months after establishing the first CR: it was the most frequent in the middle stage group (8 patients). Seven patients died: 4 died as a result of complications and the other 3 died during the first CR. (N.K.).

    Full Text Available For pregnant patients with cervical cancer, treatment recommendations are individualized and dependent on the stage of the disease, gestational age at the time of diagnosis, and the patient's desire as to the cosntinuation of the pregnancy. The aim of this study is to describe the outcome of neoadjuvant chemotherapy with radical surgery and pelvic lymphadenectomy in a woman with cervical cancer who wished to maintain her pregnancy. This is a report of a 26-week pregnant woman with locally advanced cervical cancer stage Ib2 (FIGO who was successfully treated with neoadjuvant chemotherapy Paclitaxel plus platinum, followed by C/S and radical surgery. Her neonate was healthy and had no abnormalities. This case was the first cervical cancer during pregnancy that was treated using this method at the tumor clinic, Mashhad University of Medical Sciences, Iran. Neoadjuvant chemotherapy is an effort to allow time for the fetal to reach viability by preventing the progression of the disease.

    Dosage and frequency of treatment schedules are important for successful chemotherapy. However, in this work we argue that cell-kill response and tumoral growth should not be seen as separate and therefore are essential in a mathematical cancer model. This paper presents a mathematical model for sequencing of cancer chemotherapy and surgery. Our purpose is to investigate treatments for large human tumours considering a suitable cell-kill dynamics. We use some biological and pharmacological data in a numerical approach, where drug administration occurs in cycles (periodic infusion) and surgery is performed instantaneously. Moreover, we also present an analysis of stability for a chemotherapeutic model with continuous drug administration. According to Norton and Simon [22], our results indicate that chemotherapy is less efficient in treating tumours that have reached a plateau level of growing and that a combination with surgical treatment can provide better outcomes.

    Body weight loss is a common outcome in patients with gastric cancer who have undergone gastrectomy. However, the rate of body weight loss after surgery is unknown. In this retrospective study, we selected patients who underwent radical gastrectomy for gastric cancer and were diagnosed with Stage II or III disease. Further, we compared the body weight loss after surgery between patients in the surgery alone group and the S-1 adjuvant chemotherapy group. We evaluated 163 patients, of which 81 underwent only surgery, and 82 underwent surgery followed up with S-1 adjuvant chemotherapy. The body weight loss rate at 1, 3, and 6 months in the surgery alone group were 93.1%, 92.9%, and 94.9%, while those in the S-1 adjuvant group were 92.9%, 90.4%,and 91.9%, which was a significant difference. Body weight loss after gastrectomy was higher in the S-1 adjuvant group than in the surgery alone group. Further, nutritional support is required for these patients to maintain body weight after surgery.

    Full Text Available Objective The aim of our study was to assess short and mid-term clinical efficacy of external beam radiation therapy to achieve hemostasis in patients with bladder-cancer related gross hematuria who were unfit for surgery. We also assessed hypofractionation as a possible alternative option for more severe patients. Patients and Methods Thirty-two patients were included for hemostatic radiation therapy, with two schedules based on Eastern Cooperative Oncology Group performance status. The standard treatment was 30 Gy in 10 fractions over 2 weeks. More severe patients underwent a hypofractionated regimen, with 20 Gy in 5 fractions over a one week period. Clinical evaluation was performed at 2 weeks and 6 months. Results At 2 weeks, 69% of patients were hematuria-free. Subgroup analysis showed that 79% of patients undergoing hypofractionated regimen were hematuria-free. A total of 54% were hematuria-free with the standard regimen. Based on tumor stage, hematuria was controlled at 2 weeks for 57% of non-muscle invasive tumors and 72% of muscle-invasive tumors. After 6 months, 69% of patients had relapsed, regardless of tumor stage or therapy schedules. Conclusions Hemostatic radiotherapy is an effective option for palliative-care hematuria related to bladder cancer in patients unfit for surgery. Although it appears to be rapidly effective, its effect is of limited duration. Hypofractionation also seems to be an effective option; however larger cohorts and prospective trials are needed to evaluate its efficacy compared to standard schedules.

    Background: in the therapy of brain metastases there has been a great progress in the last years. It was shown, that more aggressive therapies can not only extend the survival of the patients, but also improve quality of life. The major question of this study was, whether surgery or stereotactic radiotherapy with the linear accelerator show better results in behalf of the survival. Beside this major question many parameters regarding the patient or his primary cancer were examined. Methods: from the 1st of January 1995 until the 30th of June 2000 233 patients with one or more brain metastases have been treated in the Wagner Jauregg Landesnervenkrankenhaus Oberoesterreich (WJ LNKH OeO). The LINAC has been established on the 1st of July 1997. The patients have been distributed in three groups: 1. LINAC-group: 81 patients have been treated from the 1st of July 1997 until the 30th of June 2000 with the LINAC. 2. Surgery-group: 81 patients have been operated from the 1st of July 1997 until the 30th June 2000. 3 Co...

    Thirty-six patients with squamous cell carcinoma of the oral region were treated preoperatively with CDDP (15 mg/m{sup 2} x 3 days), PEP (5 mg/body x 4 days) or CBDCA (70-100 mg/m{sup 2} x 3 days), 5FU (500-750 mg/body x 4 days) in combination with simultaneous radiation (30-40 Gy). Thirty-three patients (91.2%) had Stage III or IV carcinomas whereas 3 patients had Stage II lesions. The clinical response was vary encouraging: 22 patients (61.1%) achieved CR, 13 patients (36.1%) were judged as PR, only one patient (2.8%) was NC, and overall response rates were 97.2%. Histological effects were seen in 33/36 (91.7%) (9 as Grade IIB, 8 as Grade III, 16 as Grade IV according to Shimosato`s classification.) and especially 72.7% of CR were histologically negative for tumor. Side effects of this therapy were minimal and reversible. With a follow-up ranging from 8-76 months, 5-year cumulative survival rates are 81.5% for all patients, and 100% as Stage II, 87.4% as Stage III, 72.8% as Stage IV, respectively. Morbidity after subsequent curative surgery is none, and histologic complete response are frequent. This preoperative combined simultaneous chemoradiotherapy appeares a highly active and well tolerated regimen for even advanced and highly malignant carcinomas of the oral cavity. (author).

    The purpose of this study was to analyze clinical outcomes from cervical cancer and stratify patients into risk groups for prognostic factors for early-stage disease. We retrospectively reviewed patients with stage IB or IIA cervical cancer treated with adjuvant radiotherapy (RT) or concurrent chemoradiotherapy (CCRT) following primary surgery at Samsung Medical Center from 2001 to 2011. Adjuvant RT was added for patients with intermediate-risk factors, and adjuvant CCRT was performed on high-risk patients after surgery. We reviewed 247 patients—149 in the high-risk group and 98 in intermediate-risk group. The median follow-up was 62 months. Loco-regional failure (LRF) alone occurred in 7 patients (2.8%), distant metastasis alone in 37 patients (15.0%) and LRF with DM in 4 patients (1.6%). The 5-year disease-free survival (DFS) and overall survival (OS) rates for both groups were 79.7% and 87.6%, respectively. In the high-risk group, the 5-year DFS and OS probabilities were 72.5% and 81.9%, respectively. Histologic type, pathologic tumor size, and the number of pelvic lymph node (PLN) metastasis were significant prognostic factors for DFS and OS. We suggest a scoring system (0–3) using these prognostic factors to predict poor prognosis in high-risk patients. Using this system, patients with higher scores have higher recurrence and lower survival rates. In the high-risk cervical-cancer group who received primary surgery and adjuvant CCRT, non-squamous type, large tumor size and the number of PLN metastasis were significant prognostic factors, and the number of these factors was associated with survival rates.

    To evaluate the sensitivity and resistance of pathogenic oral Candida spp. isolated from head and neck cancer patients treated with radiotherapy or chemotherapy to antifungal agents. To screen antifugal agents from Chinese traditional and herbal drugs by NCCLS M27-A2 method. Using YBC Test Kit to identify 20 clinical oral Candida isolated from head and neck cancer patients treated with radiotherapy or chemotherapy. The in vitro susceptibilities of 20 oral Candida spp. to 5-flucytosine (5-FC), itraconazole (ITR), fluconazole (FLU), the extracts of 6 Chinese traditional and herbal drugs (caltrop, honeysuckle flower, dandelion, green tea, pine bark, red trefoil) and utility componets of 7 Chinese traditional and herbal drugs (sophorcarpidine, aloperine, archin, glycyrrhizic acid, glycosides of white peony root, glycosides of baikal skullcap root, hydrochloric berberine) were determined by NCCLS M27-A2 method. The proportion of no-C. albicans in all Candida spp. were 25%. All strains were sensitive to 5-flucytosine, 25% stains were resistant to fluconazole and 40% stains were resistant to itraconazole. In all agents from Chinese traditional and herbal drugs, glycosides of white peony root and hydrochloric berberine (C20H18CINO4) exhibited antifungal activity, especially to C. glabrates. The proportion of no-C. albicans in all oral Candida spp. isolated from head and neck cancer patients treated with radiotherapy or chemotherapy was pretty high. NCCLS M27-A2 micro-dilution method is a reliable and reproducible method and can be used to screen antifugal agents from Chinese traditional and herbal drugs.

    Full Text Available Objective. To elucidate the optimum preoperative biliary drainage method for patients with pancreatic cancer treated with neoadjuvant chemotherapy (NAC. Material and Methods. From January 2010 through December 2014, 20 patients with borderline resectable pancreatic cancer underwent preoperative biliary drainage and NAC with a plastic or metallic stent and received NAC at Hiroshima University Hospital. We retrospectively analyzed delayed NAC and complication rates due to biliary drainage, effect of stent type on perioperative factors, and hospitalization costs from diagnosis to surgery. Results. There were 11 cases of preoperative biliary drainage with plastic stents and nine metallic stents. The median age was 64.5 years; delayed NAC occurred in 9 cases with plastic stent and 1 case with metallic stent (p=0.01. The complication rates due to biliary drainage were 0% (0/9 with metallic stents and 72.7% (8/11 with plastic stents (p=0.01. Cumulative rates of complications determined with the Kaplan-Meier method on day 90 were 60% with plastic stents and 0% with metallic stents (log-rank test, p=0.012. There were no significant differences between group in perioperative factors or hospitalization costs from diagnosis to surgery. Conclusions. Metallic stent implantation may be effective for preoperative biliary drainage for pancreatic cancer treated with NAC.

    Stomatitis is well-known as one of the undesirable side effects induced by high and/or multiple dosing of cytotoxic drugs such as 5-fluorouracil (5-FU). Stomatitis causes pain in the oral cavity, impaired swallowing or loss of appetite, and finally, lowering of the quality of life (QOL) of patients. In this study, we attempted to apply a new mouthwash containing rebamipide (REB) which is known as the anti-activated oxygen agent. Rebamipide mouthwash (REB-M) showed the effectiveness to the crisis of the stomatitis during the cancer chemotherapy and/or radiotherapy. (author)

    Background and purpose: the formation of inguinal lymphorrhea following vascular surgery is a rare but potentially serious problem with an incidence of about 2%. There is no consensus on the most effective treatment for groin lymphorrhea. In a retrospective analysis the usefulness of irradiation in the treatment of inguinal lymph fistulas was investigated. Patients and methods: from 08/1997 to 12/2000, 28 patients with inguinal lymph fistulas were irradiated postoperatively (4th-19th day) with a single dose of 3 Gy up to a total dose of 9 Gy on 3 consecutive days using 120- to 300-kV photons. Three further patients received 2 x 4 Gy and 3 x 5 Gy, respectively, due to an interposed weekend. Results: secretion volume at the beginning of radiotherapy varied between 50 and 650 ml daily (mean 203 ml, median 175 ml), at the end of radiotherapy between 0 and 350 ml (mean 126 ml, median 120 ml). 3/28 lymph fistulas had resolved during radiotherapy. In 17/28 patients (60.7%) the drains could be removed within 10 days, in further 10/28 patients (35.7%) within 10-20 days after the end of radiotherapy. Conclusion: overall, irradiation of inguinal lymph fistulas proved to be an effective and well-tolerated treatment, facilitating removal of fistula drains within 10-20 days (mean 10.5, median 7 days) after the completion of radiotherapy, thus appearing a good alternative to other conservative treatment modalities.

    The purpose of this study is to evaluate whether adjuvant chemotherapy could bring oncologic benefit to all patients who underwent neoadjuvant radiotherapy (30Gy/10f). Rectal cancer patients receiving preoperative radiotherapy between July 2002 and April 2009 were retrospectively identified. A total of 225 patients were enrolled in this study. One hundred thirty-one patients received postoperative adjuvant chemotherapy, and 94 patients did not. The 120 ypN+ and 105 ypN- patients were divided into chemo and non-chemo groups. Two groups of patients did not show any significant difference in terms of gender, age, ypT stage, preoperative serum carcinoembryonic antigen (CEA) level, differentiation, circumferential margin (CRM), lymphovascular invasion (LVI), surgical approach, local recurrence, and distant metastasis (P > 0.05). Survival analysis showed that in ypN+ patients, the 5-year overall survival (OS) rate and 5-year disease-free survival (DFS) rate in chemo group were both significantly higher than non-chemo group (P 0.05). Subgroup analysis showed that the 5-year OS rate and 5-year DFS rate in ypT0-2 N- patients (P > 0.05) and ypT3-4 N- patients (P > 0.05) did not show any significant difference, either. Based on a Chinese protocol, patients with ypN- stage may not benefit from adjuvant chemotherapy, regardless of the ypT stage, while the ypN+ patients may benefit from adjuvant chemotherapy. More randomized clinical trials are needed in the future.

    Neoadjuvant chemotherapy [NACT] followed by radical hysterectomy is an alternative therapeutic option to concurrent chemotherapy-radiotherapy for locally advanced cervical cancer. However there are very few data about the effectiveness of any post-operative treatment in this clinical setting. The purpose of this study was to correlate the patterns of recurrence and the clinical outcomes of cervical cancer patients who received NACT, with postoperative adjuvant treatment. This retrospective multicenter study included 333 patients with FIGO stage Ib2-IIb cervical cancer who underwent platinum-based NACT followed by radical surgery. Pathological responses were retrospectively assessed as complete; optimal partial; and suboptimal response. Overall optimal response rate was the sum of complete and optimal partial response rates. On the whole series, recurrence-free survival was significantly longer in patients who achieved an overall optimal response than in those who did not (ptreatment for FIGO stage Ib2-IIb cervical cancer do not need any further treatment. Additional cycles of chemotherapy could be of benefit for patients with suboptimal response and intra-cervical residual disease. Both adjuvant chemotherapy and adjuvant radiation treatments do not seem to improve the clinical outcome of patients with extra-cervical residual disease compared to no further treatment.

    Full Text Available Introduction : Cancer pain is chronic pain resulting from various mechanisms related to the natural history of the disease, the course of therapy, and psychosocial factors. Aim of the research : To assess the relationship between the intensity of cancer pain in women at the final stage of chemotherapy following radical surgery of breast cancer, and the intensity of negative emotional reactions. Material and methods : The study was conducted in a population of 118 women after radical surgical treatment of breast cancer and undergoing chemotherapy at the Chemotherapy Unit of the Holycross Cancer Centre in Kielce in 2011. The research methodology consisted of a diagnostic survey and medical documentation review. Results: Strong emotional stress manifested by anxiety and depression was experienced by 48.3% and 29.7% of patients, respectively. Aggression was experienced by 15.2%. Intensification of pain was associated with the intensification of anxiety (r = 0.37; p < 0.0001, depression (r = 0.35; p < 0.01, and aggression (r = 0.30; p < 0.01. Conclusions: Adherence to the WHO-recommended analgesic ladder regimen is an effective means to treat chronic cancer pain in women in the final stage of chemotherapy following radical surgical treatment. Effective pharmacotherapy of cancer pain significantly contributes to a reduction in the intensity of negative emotional reactions, i.e. anxiety, depression, and aggression in patients undergoing chemotherapy following mastectomy. Breast cancer chemotherapy is associated with high levels of anxiety, pain, and aggression being experienced by the patients. Pain is an important determinant of the emotional state of women undergoing chemotherapy following radical cancer surgery.

    Cytoreductive surgery (CRS) followed by hyperthermic intraperitoneal chemotherapy (HIPEC) is a radical but effective treatment option for select peritoneal malignancies. We sought to determine our early experience with this method for peritoneal carcinomatosis secondary to mucinous adenocarcinomas of appendiceal origin. As such, we performed a retrospective clinical study of 30 consecutive patients undergoing CRS with planned HIPEC at the Princess Alexandra Hospital, between June 2009 to December 2012, with mucinous adenocarcinomas of the appendix. CRS was performed in 30 patients, 13 received HIPEC intraoperatively and 17 received early postoperative intra-peritoneal chemotherapy (EPIC) in addition. Mean age was 52.3 years and median hospital stay was 26 days (range 12–190 days). Peritoneal cancer index scores were 0–10 in 6.7% of patients, 11–20 in 20% of patients and >20 in 73.3% of patients. Complete cytoreduction was achieved overall in 21 patients. In total, 106 complications were observed in 28 patients. Ten were grade 3-A, five were grade 3-B and one grade-5 secondary to a fatal PE on day 97. In patients who received HIPEC, there was no difference in disease-free survival (P = 0.098) or overall survival (P = 0.645) between those who received EPIC versus those who did not. This study demonstrates that satisfactory outcomes with regards to morbidity and survival can be achieved with CRS and HIPEC, at a single-centre institution with growing expertise in the technique. Our results are comparable with outcomes previously described in the international literature. PMID:25594636

    To evaluate the effect of postmastectomy radiotherapy (PMRT) in Stage II-III breast cancer patients with negative lymph nodes (pN0) after neoadjuvant chemotherapy (NAC). Of 1,054 breast cancer patients treated with NAC at our institution between 1990 and 2004, 134 had pN0 status after NAC and mastectomy. The demographic data, tumor characteristics, metastatic sites, and treatments were prospectively recorded. The effect of PMRT on locoregional recurrence-free survival and overall survival (OS) was evaluated by multivariate analysis, including known prognostic factors. Of the 134 eligible patients, 78 (58.2%) received PMRT and 56 (41.8%) did not. At a median follow-up time of 91.4 months, the 5-year locoregional recurrence-free survival and OS rate was 96.2% and 88.3% with PMRT and 92.5% and 94.3% without PMRT, respectively (p = NS). The corresponding values at 10 years were 96.2% and 77.2% with PMRT and 86.8% and 87.7% without PMRT (p = NS). On multivariate analysis, PMRT had no effect on either locoregional recurrence-free survival (hazard ratio, 0.37; 95% confidence interval, 0.09-1.61; p = .18) or OS (hazard ratio, 2.06; 95% confidence interval, 0.71-6; p = .18). This remained true in the subgroups of patients with clinical Stage II or Stage III disease at diagnosis. A trend was seen toward poorer OS among patients who had not had a pathologic complete in-breast tumor response after NAC (hazard ratio, 6.65; 95% confidence interval, 0.82-54.12; p = .076). The results from the present retrospective study showed no increase in the risk of distant metastasis, locoregional recurrence, or death when PMRT was omitted in breast cancer patients with pN0 status after NAC and mastectomy. Whether the omission of PMRT is acceptable for these patients should be addressed prospectively. Copyright © 2012 Elsevier Inc. All rights reserved.

    In order to evaluate the influence of time intervals between tumor cell injection and radiotherapy on tumor control and regrowth after surgery, we performed two kinds of experiments on C3D2F1 mice bearing a mammary carcinoma inoculated in the foot or leg. 1. experiment: tumor in foot. End point: Tumor Control Probability (TCP). Single dose radiation treatments (RT) were administered at different period times from injection time of tumor cells (day 1). 1. group: unirradiated control, 2. group: RT on day 2 (TCP50 29{+-}2.1 Gy), 3. group: RT on day 7 (TCP 52.5{+-}2.9 Gy), 4. group: RT on day 12 (TCP50 61.9{+-}2.4 Gy). 2. experiment: tumor in leg. End point: percentage of tumor regrowth. Mice were randomly assigned to three groups: 1. control group (tumor growth in all mice), 2. surgical excision of macroscopically evident tumor on day 7-9 from injection (tumor regrowth in 85% of mice), 3. as the previous group plus 30 Gy radiation treatment within 24 hours from excision (tumor regrowth in 33% of cases). The radiation dose was selected on the basis of TCP50 observed in the 1. experiment for mice with sub-clinical disease. These data indicate that the radiation dose able to control 50% of tumors increases with the time interval between tumor cells injection and RT. A short time interval between surgery and RT should increase the probability of local control, supporting the rationale of intraoperative radiation therapy (IORT) as adjuvant therapy after surgical resection, when subclinical residual cells are suspected.

    Introduction. Patients with head and neck cancer suffer from various impairments due to the primary illness, as well as secondary consequences of the oncological treatment. This systematic review describes the effects of radiotherapy and/or chemotherapy on the functions of the upper aerodigestive tract in patients with head and neck cancer. Methods. A systematic literature search was performed by two independent reviewers using the electronic databases PubMed and Embase. All dates up to May 2016 were included. Results. Of the 947 abstracts, sixty articles met the inclusion criteria and described one or more aspects of the sequelae of radiotherapy and/or chemotherapy. Forty studies described swallowing-related problems, 24 described voice-related problems, seven described trismus, and 25 studies described general quality of life. Only 14 articles reported that speech pathologists conducted the interventions, of which only six articles described in detail what the interventions involved. Conclusion. In general, voice quality improved following intervention, whereas quality of life, dysphagia, and oral intake deteriorated during and after treatment. However, as a consequence of the diversity in treatment protocols and patient characteristics, the conclusions of most studies cannot be easily generalised. Further research on the effects of oncological interventions on the upper aerodigestive tract is needed.

    Full Text Available Introduction. Patients with head and neck cancer suffer from various impairments due to the primary illness, as well as secondary consequences of the oncological treatment. This systematic review describes the effects of radiotherapy and/or chemotherapy on the functions of the upper aerodigestive tract in patients with head and neck cancer. Methods. A systematic literature search was performed by two independent reviewers using the electronic databases PubMed and Embase. All dates up to May 2016 were included. Results. Of the 947 abstracts, sixty articles met the inclusion criteria and described one or more aspects of the sequelae of radiotherapy and/or chemotherapy. Forty studies described swallowing-related problems, 24 described voice-related problems, seven described trismus, and 25 studies described general quality of life. Only 14 articles reported that speech pathologists conducted the interventions, of which only six articles described in detail what the interventions involved. Conclusion. In general, voice quality improved following intervention, whereas quality of life, dysphagia, and oral intake deteriorated during and after treatment. However, as a consequence of the diversity in treatment protocols and patient characteristics, the conclusions of most studies cannot be easily generalised. Further research on the effects of oncological interventions on the upper aerodigestive tract is needed.

    Background The selection of the most appropriate treatment combinations requires the balancing of benefits and harms of these treatment options as well as the patients’ preferences for the resulting outcomes. Objective This research aimed at estimating and comparing the utility weights between elderly women with early stage hormone receptor positive (HR+) breast cancer receiving a combination of radiotherapy and hormonal therapy after breast conserving surgery (BCS) and those receiving a combination of BCS and hormonal therapy. Methods The Surveillance, Epidemiology, and End Results (SEER) linked with Medicare Health Outcomes Survey (MHOS) was used as the data source. Health utility weights were derived from the VR-12 health-related quality of life instrument using a mapping algorithm. Descriptive statistics of the sample were provided. Two sample t-tests were performed to determine potential differences in mean health utility weights between the two groups after propensity score matching. Results The average age at diagnosis was 72 vs. 76 years for the treated and the untreated groups, respectively. The results showed an inverse relationship between the receipt of radiotherapy and age. Patients who received radiotherapy had, on average, a higher health utility weight (0.70; SD = 0.123) compared with those who did not receive radiotherapy (0.676; SD = 0.130). Only treated patients who had more than two comorbid conditions had significantly higher health utility weights compared with patients who were not treated. Conclusions The mean health utility weights estimated for the radiotherapy and no radiotherapy groups can be used to inform a comparative cost-effectiveness analysis of the treatment options. However, the results of this study may not be generalizable to those who are outside a managed care plan because MHOS data is collected on managed care beneficiaries. PMID:27819160

    Incidence of, and baseline characteristics associated with delirium in patients after cytoreduction surgery-hyperthermic intraperitoneal chemotherapy (CRS-HIPEC), were subject of investigation. The study was conducted among a consecutive series of prospectively included patients who underwent CRS-HIPEC at the University Medical Center Groningen, Groningen, the Netherlands, between February 2006 and January 2015. A chart-based instrument for delirium during hospitalization was used to identify patients with symptoms of delirium who were not diagnosed by a psychiatrist during admission. Uni- and multivariate logistic regression analyses were performed. Data of 136 patients were included in the analysis. Median age was 60 years (range: 18-76) and 50 (37%) patients were male. During hospitalization, 38 (28%) patients were diagnosed with delirium. Factors that differed significantly between the patients with and without delirium by univariate analysis were included in multivariate analysis. Multivariate analysis showed that after adjustment for age and complications other than delirium, having three or more organs resected and the CRP serum levels were independent predictors for delirium (OR: 3.97; 95% 1.24-12.76; OR: 1.01; 95% 1-1.01, respectively). This report shows an incidence of 28% of delirium, occurring after CRS-HIPEC and suggests a role for systemic inflammation in the development of postoperative delirium. © 2017 Wiley Periodicals, Inc.

    Full Text Available Desmoplastic small round cell tumor (DSRCT is a very rare disease of children, adolescents, and young adults and involves the abdominal cavity. DSRCT has characteristic fusion gene involving EWS1 and WT1 translocation, t(11;22(p13;q12. Unlike Ewing’s sarcoma of bone, DSRCT usually presents with diffuse peritoneal implants that are prone to recur. The primary organ of origin of DSRCT is mesenchyme of the peritoneum. This makes it a very unique tumor that is difficult to treat because of the infiltrative and diffuse nature of the peritoneum. The challenge of local control is to remove dozens to hundreds of tumors studding the peritoneal cavity, and then eliminate microscopic disease. We review a sequential multimodality strategy to reduce macroscopic and microscopic disease including neoadjuvant chemotherapy, aggressive surgery including an emerging new therapy to use after surgery to treat microscopic residual disease: continuous hyperthermic peritoneal chemotherapy,

    The authors discuss the characteristics and the radiotherapy treatment procedures of cystic adenoid carcinomas, and more precisely the treatment of two of such cases of nasopharyngeal carcinomas. The first one had an incomplete resection surgery followed by curing radiotherapy: he has then been in local-regional control situation for 8 months. The second one had lung metastases, was treated chemotherapy and radiotherapy (decompressive treatment), and died six months after diagnosis. Radiotherapy is considered to be the treatment basis, whereas chemotherapy is a matter of controversy. Short communication

    This meta-analysis was performed to compare the outcomes between NACT-S and RT for locally advanced cancer cervix. The primary end points were survival benefits. The data sources for the search included medline, national library of medicine, and the embase search engines. Inclusion criteria included studies published between 2000 and 2012, and FIGO stages IB2 to IVA. Studies had to be properly randomized, prospective, or retrospective and only phase III. Further, the studies had to be with two arms, including one arm for neoadjuvant chemotherapy then-surgery (NACT-S), and the other arm for radiotherapy (RT). Data were collected from 1171 patients enrolled in seven phase III trials. The 5-year PFS (progression-free survival) for NACT-S and RT were 62 and 45.5 %, respectively. The 5-year OS for NACT-S and RT were 66 and 49 %, respectively. NACT-S was associated with better late toxicities compared to RT. NACT-S is a reasonable treatment option for locally advanced cancer cervix. It achieved better results than RT, especially for stages from IB2 to IIB.

    Both induction chemotherapy and concurrent platinating agents have been shown to improve results of thoracic irradiation in the treatment of locally advanced non-small-cell lung cancer (NSCLC). This phase II study investigated activity and feasibility of a novel chemoradiation regimen, including platinum and paclitaxel, both as induction chemotherapy and concurrently with thoracic radiotherapy. Previously untreated patients with histologically/cytologically proven unresectable stage I-III NSCLC were eligible. Induction chemotherapy consisted of 2 courses of 200 mg/m2 paclitaxel and carboplatin at AUC of 6 mg/mL/min every 3 weeks. From day 43, continuous thoracic irradiation (60 Gy in 30 fractions radiotherapy for 6 weeks) was given concurrently with daily cisplatin at a dose of 5 mg/m2 intravenously and weekly paclitaxel at a dose of 45 mg/m2 for 6 weeks. Fifteen patients were accrued in the first stage of the trial. According to the previous statistical considerations, accrual at the second stage of the study was halted as a result of the achievement an insufficient number of successes. Major toxicity of combined chemoradiation was grade III-IV esophagitis requiring hospitalization for artificial nutrition, which occurred in 58% of patients. Other toxicities included grade II-IV fatigue in 75% of patients and grade I-IV neuromuscular toxicity in 67%. Only 7 patients completed the treatment program as scheduled. Eight patients (53.3%; 95% confidence interval, 26.5-78.7%) had a major response (5 partial response, 3 complete response), 2 patients had disease progression, and 1 was stable at the end of treatment. Four patients died early. With a median follow up of 38 months, the median survival was 12 months. A combined chemoradiation program, including platinum and paclitaxel, appears difficult to deliver at full dose as a result of toxicity, mainly esophagitis. More active and less toxic combined modality treatments need to be developed for inoperable NSCLC.

    To evaluate the prognostic properties of retropharyngeal lymph node (RP), posterior cervical lymph node (PCN), and supraclavicular lymph node (SPC), in stage IVA/IVB nasopharyngeal carcinoma (NPC) patients in setting of induction chemotherapy. We performed a retrospective study including 43 patients with stage IVA/IVB NPC (7th AJCC) treated with induction chemotherapy followed by concurrent chemo-radiotherapy. We analyzed prognosis with the multivariate Cox regression model and p-value from the Wald's test, using the backward elimination method (by likelihood ratio test and percent change of coefficient factors). Overall, 24 patients (55.8%) were in stage IVA and 19 (44.2%) in stage IVB. After a median follow-up time of 30 months, the 2-year overall survival (OS) was 79.1%, while the 2-year progression free survival (PFS) and distant metastasis free survival (DMFS) were 59.8% and 69.1%, respectively. In multivariate analysis for predicting DMFS, SPC involvement was not statistically significant (HR 3.39; 95% CI 0.76-15.07; p=0.1), whereas RP involvement was statistically significant (HR 5.81; 95% CI 1.08-31.16; p=0.04). Moreover, and more importantly, PCN involvement was the only nodal factor to predict all of DMFS, PFS, and OS (respectively HR 5.57, 95% CI 1.12-27.71, p=0.036; HR 16.05, 95% CI 1.93-133.65, p=0.01; and HR 28.02, 95% CI 2.74-286.22, p=0.005). PCN involvement is the only independent prognostic factor of stage IVA/IVB NPC patients treated by induction chemotherapy that predicts DMFS and turns this effect to PFS and OS. PCN involvement is a highly accurate predictor for failure of conventional chemo-radiotherapy. Therefore, patients with PCN involvement should be defined at high-risk, as to be investigated for a new staging system.

    Antineoplastic chemotherapy (CT) represents the systemic treatment of malignant tumors. It can be used alone or combined with surgery and / or radiotherapy. The cytotoxic agents used in chemotherapy work on both cancerous cells and noncancerous cells of the body, generally resulting in high toxicity. The biological aggressiveness of chemotherapy particularly affects rapidly replicating cells, such as those of the digestive tract, resulting in adverse effects that impair food intake, leading t...

  6. Vascular Endothelial-Targeted Therapy Combined with Cytotoxic Chemotherapy Induces Inflammatory Intratumoral Infiltrates and Inhibits Tumor Relapses after Surgery

    Full Text Available Surgery is the most effective therapy for cancer in the United States, but disease still recurs in more than 40% of patients within 5 years after resection. Chemotherapy is given postoperatively to prevent relapses; however, this approach has had marginal success. After surgery, recurrent tumors depend on rapid neovascular proliferation to deliver nutrients and oxygen. Phosphatidylserine (PS is exposed on the vascular endothelial cells in the tumor microenvironment but is notably absent on blood vessels in normal tissues. Thus, PS is an attractive target for cancer therapy after surgery. Syngeneic mice bearing TC1 lung cancer tumors were treated with mch1N11 (a novel mouse chimeric monoclonal antibody that targets PS, cisplatin (cis, or combination after surgery. Tumor relapses and disease progression were decreased 90% by combination therapy compared with a 50% response rate for cis alone (P = .02. Mice receiving postoperative mch1N11 had no wound-related complications or added systemic toxicity in comparison to control animals. Mechanistic studies demonstrated that the effects of mch1N11 were associated with a dense infiltration of inflammatory cells, particularly granulocytes. This strategy was independent of the adaptive immune system. Together, these data suggest that vascular-targeted strategies directed against exposed PS may be a powerful adjunct to postoperative chemotherapy in preventing relapses after cancer surgery.

    Full Text Available This study assesses the morbidity and complications of treatment among long-term survivors of cervical cancer. Ninety-eight female patients who were diagnosed and treated from invasive carcinoma of the cervix uteri 5 years or more are included in this study. All the cases were free of disease and had survived up to December 2010. Forty-one cases were treated with radical hysterectomy with removal of the lymph nodes (Wertheim’s surgery (42%. Radical radiation therapy was given to 57 cases (58% according to our treatment protocol; weekly cisplatin was given concomitantly with radiation. Although urinary adverse effects were more prevalent among the radiation group, the difference was not statistically significant. Bowel dysfunction was more prevalent and statistically significant (p\\0.001 among the radiotherapy arm. Dysfunctions recorded included change in bowel habit, diarrhea, constipation, tenesmus, soiling of clothes and or flatulence. However, their severity was grade 1–2 only. The frequency of small intestinal obstruction was comparable in both arms. Pelvic vein thromboses had a tendency to occur among the surgical group especially in obese females (p value 0.005. The frequency of sexual dysfunction was comparable in both groups with no statistical difference. It was age related. The younger the patients’ ages, the more was the sexual complaint irrespective to the treatment modality. Sexual problems included dyspareunia from vaginal stenosis shortening or dryness, vulval soreness from itching and dryness. Bearing in mind that many patients had more than one health complaint. The remaining cases denied the presence of any complications and stated that they had a normal life style.

    The purpose of this study was to analyze the probability and time course of fibrotic changes in breast reconstruction before or after postmastectomy radiotherapy (PMRT). Between 1995 and 2004, 109 patients were treated with PMRT at Tuebingen University and underwent heterologous (HL) or autologous (AL) breast reconstruction prior or subsequent to radiation therapy. Fibrosis of the reconstructed breast after radiotherapy was assessed using the Baker score for HL reconstructions and the Common Terminology Criteria for Adverse Events (CTCAE) for all patients. Actuarial rates of fibrosis were calculated for the maximum degree acquired during follow- up and at the last follow-up visit documented. Median time to follow-up was 34 months (3-227 months). Radiotherapy was applied with a median total dose of 50.4 Gy. A total of 44 patients (40.4%) received a boost treatment with a median dose of 10 Gy. Breast reconstruction was performed with AL, HL, or combined techniques in 20, 82, and 7 patients, respectively. The 3-year incidence of {>=} grade III maximum fibrosis was 20% and 43% for Baker and CTCAE scores, respectively. The corresponding figures for fibrosis at last follow-up visit were 18% and 2%. The 3-year rate of surgical correction of the contralateral breast was 30%. Initially unplanned surgery of the reconstructed breast was performed in 39 patients (35.8%). Boost treatment and type of cosmetic surgery (HL vs. AL) were not significantly associated with the incidence of fibrosis. We found severe fibrosis to be a frequent complication after PMRT radiotherapy and breast reconstruction. However, surgical intervention can ameliorate the majority of high grade fibrotic events leading to acceptable long-term results. No treatment parameters associated with the rate of fibrosis could be identified. (orig.)

    Peritoneal mesothelioma is a rare disease with poor prognosis. The present study reports single center experience with cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy with oxaliplatin (HIPEC-OX) over an eight-year period. Prospectively collected data of all consecutive patients with epithelial or multicystic peritoneal mesothelioma from August 2004 to October 2012 was analyzed. Patients with sarcomatoid or biphasic peritoneal mesothelioma were not included due to general poor prognosis. Treatment consisted in CRS and HIPEC-OX (460 mg/m(2)) at 43 °C during 30 min. For statistical analysis, Kaplan-Meier survival curves were plotted and compared using log-rank tests. Cox proportional-hazards regression model was used to analyze the influence of different variables on survival. Nineteen patients with peritoneal mesothelioma underwent laparotomy with CRS and HIPEC-OX with curative intent (15 epithelial, and 4 multicystic). Mean follow-up was 36.7 months. The estimated one-year and three-year overall survival rates were respectively 100% and 91%. The estimated one-year and three-year disease-free survival rates were respectively 77% and 50%. Complications were graded according to the Clavien-Dindo classification [1] and major complications occurred in 57% of cases. There was no postoperative mortality. Histological grade was not a prognostic factor of disease-free survival (p = 0.37). When comparing survival results as well as morbidity-mortality rates, the present study shows that CRS and HIPEC-OX is a valid treatment for peritoneal mesothelioma. Copyright © 2014 Elsevier Ltd.

    Full Text Available The aim of the present meta-analysis is to evaluate the response rate, median survival time (MST and toxicity in patients with brain metastases (BM originating from non-small cell lung cancer (NSCLC and who were treated using either whole brain radiotherapy (WBRT plus concurrent chemotherapy or WBRT alone.PubMed, EMBASE, Web of Science, The Cochrane Library, clinical trials and current controlled trials were searched to identify any relevant publications. After screening the literature and undertaking quality assessment and data extraction, the meta-analysis was performed using Stata11.0 software.In total, six randomized controlled trials (RCT involving 910 participants were included in the meta-analysis. The results of the analysis indicate that WBRT plus concurrent chemotherapy was more effective at improving response rate (RR = 2.06, 95% CI [1.13, 3.77]; P = 0.019 than WBRT alone. However, WBRT plus concurrent chemotherapy did not improve median survival time (MST (HR = 1.09, 95%CI [0.94, 1.26]; P = 0.233 or time of neurological progression (CNS-TTP (HR = 0.93, 95%CI [0.75, 1.16]; P = 0.543, and increased adverse events (Grade≥3 (RR = 2.59, 95% CI [1.88, 3.58]; P = 0.000. There were no significant differences in Grade 3-5 neurological or hematological toxicity between two patient groups (RR = 1.08, 95%CI [0.23, 5.1]; P = 0.92.The combination of chemotherapy plus WBRT in patients with BM originating from NSCLC may increase treatment response rates of brain metastases with limited toxicity. Although the therapy schedule did not prolong MST or CNS-TTP, further assessment is warranted.

The present study examines its influence on the short-term toxicity of either radiotherapy alone or combined radio-chemotherapy in patients with advanced head and neck cancer. Patients and methods: Twenty-three patients with advanced head and neck cancer, mainly Stage III and IV, were treated with preoperative radiation (n=1), pre- as well as postoperative radiotherapy (n=5), postoperative radiation (n=9) or combined postoperative radio-chemotherapy (n=6). Before each radiation application a total dose of 500 mg amifostine was administered intravenously over 15 minutes. The documentation of this unselected patient group was compared retrospectively to a historical control group comprising 17 patients. Results: In 15 patients (65%) of the amifostine group, therapy induced side effects such as mucositis and dermatitis of WHO Grade {<=}2 were detected, requiring interruptions of the radiotherapy (mean: 6.5, maximum 17 days). No mucosa or dermatologic toxicity of WHO Grade 3 or 4 was observed in this group. Significantly more acute toxicity was detected in the historical control group. Stomatitis or epitheliolysis of WHO Grade 3 occurred in 7 patients (41%). The side effects induced by the antineoplastic therapy caused an interruption of treatment in 15 patients (88%) (mean: 16, maximum 40 days; p=0.0016). Conclusion: The application of amifostine before each radiation treatment seems to result in a distinct reduction of short-term toxicity of radiotherapy or combined radio-chemotherapy in patients with head and neck cancer, allowing for a better adherence to the planned radiation time schedule.

    A line of investigation in the search for sensitizing tumor cells to chemotherapy or radiotherapy relies on the selection of DNA repair inhibitors. In the area of DNA repair mechanisms, DNA-dependent protein kinase (DNA-PK) represents a key complex. Indeed DNA-PK is involved in the non-homologous end joining (NHEJ) process that corresponds to the major activity responsible for cell survival after ionizing radiation or chemotherapeutic treatment producing DNA double strand breaks. DNA-PK belongs to the PI3-K related kinase family and specific inhibitors have been recently selected and evaluated as radio- and chemo-sensitizers. These drugs, along with other ways to inhibit the DSBs repair process, are presented and discussed. (authors)

    Full Text Available Oral changes following radiotherapy are not uncommon. Oral mucositis, alteration in salivary gland function, radiation caries, and gingival changes have all been reported following radiotherapy and chemotherapy. The gingival changes seen after radiotherapy may be unusual and often cause diagnostic dilemma. Metastasis to the gingiva has also to be ruled out in these cases. A 30-year-old female patient presented with enlargement of the gingiva of 6 months′ duration and lower lip swelling of 7 months′ duration. She was a known case of carcinoma of nasopharynx and had received radiotherapy and chemotherapy. Based on the history, the clinical appearance of the gingiva, and the other oral changes we considered both post-radiotherapy gingival enlargement and secondary metastasis to gingiva as possibilities. An incisional biopsy was performed (internal bevel gingivectomy. The histopathological report did not reveal any metastatic changes. Thus, we diagnosed post-radiotherapy gingival enlargement. For the multiple carious teeth, extraction and root canal treatment was carried out as necessary. The patient was referred to the department of Oral and Maxillofacial Surgery for management of swelling of the lips, which was diagnosed as lymphedema of the lip. Gingival enlargement is rare post radiotherapy. Such nonplaque-associated gingival enlargement in a patient who has undergone radiotherapy should be subjected to biopsy and histopathological examination to distinguish between secondary metastasis and post-radiation changes.

    One of the complications of radiotherapy and chemotherapy is oral mucositis. Since the low energy laser is one of the most frequently recommended interventions by authors and international societies, the aim of this study is to review the scientific evidence on the use of lasers as a preventive and therapeutic in oral mucositis associated with treatment of cancer. We performed a literature search in PubMed and The Cochrane Collaboration Library, limiting the search to the last 20 years. We finally included 29 articles that contained 30 studies. Low energy laser phototherapy seems a promising intervention in both the prevention and treatment of oral mucositis associated with cancer treatment. Virtually all studies reviewed showed good results with no adverse effects and reductions in both incidence and severity of mucositis in all types of cancer treatments.

    Conclusion: This retrospective case series describes, for the first time, the clinical outcomes in a series of patients treated with radiotherapy for bone hydatid disease. Although no direct comparison between the treatment groups could be made due to methodological limitations of the study design, this study indicates that well-designed prospective randomized controlled clinical trials assessing radiotherapy may be warranted in patients with inoperable hydatid disease of the bones.

    This article describes the unique case of a female patient who presented distant melanoma metastasis on the breast while having irradiation therapy for breast cancer. This happened eight months after the initial treatment for a melanoma of the back (under the right scapula). Furthermore, this case report demonstrates the efficiency of Vemurafenib® as a treatment for late stage melanomas. The patient was a 47-year-old female that had a superficial spreading melanoma under the right scapula (Breslow 1.02mm) that was treated with 2cm skin excision and sentinel lymph node sampling that was negative. The melanoma was positive for the BRAF600E mutation. One month after this incident, the patient developed breast cancer that was treated with conservative surgery and radiotherapy. Three months after the end of the irradiation treatment, she developed multiple melanoma metastasis on the skin of the breast. Our multidisciplinary team decided to initiate a treatment with vemurafenib. The patient showed an excellent response, so the surgical team completed the treatment with a radical mastectomy and immediate reconstruction with a pedicled latissimus dorsi flap. The histologic report of the mastectomy specimen showed no sign of melanocytic proliferation, that demonstrates the efficacy of vemurafenib. The patient showed no relapse after two years of follow-up. The speed of development and location of cutaneous metastases in this case brought us to think about the effects of radiation therapy on the skin. Radiation therapy causes acute complications (radiodermatitis) by cellular and molecular mechanisms. Moreover, depressed immunity is found after irradiation. Association of these mecanisms could explain the appearance of these metastases in irradiation field. The efficiency of vemurafenib found in our case is consistent with what is described in literature, especially with the improvement in median overall survival. This case demonstrates a unique case of distant melanoma

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

    Poorly differentiated neuroendocrine carcinoma has a poor prognosis, especially when associated with distant metastasis. A 60-year-old man was admitted to a private hospital because of dyspnea at work in 2007. Computed tomography revealed lung infarction and a right adrenal tumor sized 12 cm in diameter that was tightly compressed against the inferior vena cava (IVC). Moreover, multiple lymph node metastases around the celiac axis and a solitary liver metastasis at the lateral segment were observed. Thus, we planned chemotherapy without surgery. We selected a combination therapy of irinotecan (CPT-11) and cisplatin (CDDP) (i.e., IP therapy): administration of CDDP [60 mg/m(2) body surface area (BSA)] on day 1 plus CPT-11 (80 mg/m(2)) BSA on days 1 and 8. Thereafter, this protocol was repeated at 3-week intervals. After 15 months of this chemotherapy strategy, the whole lesions showed a partial response by RECIST. The primary tumor had shrunk to 4.2 cm in diameter. In November 2008, we planned surgery to perform resection of the whole lesions. Histological diagnosis of the specimen was a poorly differentiated neuroendocrine carcinoma based on the immunostaining features, i.e., synaptophysin- and chromogranin positive. There were no viable tumor cells at the dissected lymph nodes or at the liver tumor. After surgery, CPT-11 administration was continued. The patient has remained well for 9 months without recurrence.

    Full Text Available Objectives. Retrospective review of our experience using intensity-modulated radiotherapy with simultaneous integrated boost (SIB-IMRT combined with chemotherapy as the primary treatment of locoregionally advanced larynx and hypopharynx cancers. Materials and Methods. Between September 2008 and June 2012, 60 patients (26 with larynx and 34 hypopharynx cancers were treated. Our policy was to offer SIB-IMRT plus concurrent cisplatin to patients affected by larynx cancer stage T3N0-N1 and NCT with TPF (docetaxel/cisplatin/fluorouracil followed by SIB-IMRT to patients with larynx cancer stage T2-4N2-3 or hypopharynx cancer T2-4N0-3. SIB-IMRT consisted in a total dose of 70.95 Gy (2.15 Gy/fraction, 5 fractions/week to the gross primary and nodal disease and differentiated dosages for high risk and low risk nodal regions. Results. Complete remission was achieved in 53/60 (88% of patients. At a median follow up of 31 months (range 9–67, the rate of overall survival and locoregional control with functional larynx at 3 years were 68% and 60%, respectively. T stage (T1–3 versus T4 resulted in being significant for predicting 3-year freedom from relapse (it was 69% and 35%, resp., for T1–T3 and T4 tumors; P=0.04, while site of primary disease (larynx versus hypopharynx was not significant (P=0.35. Conclusion. Our results indicated that combining SIB-IMRT with induction chemotherapy or concurrent chemotherapy is an effective treatment strategy for organ preservation in advanced larynx/hypopharynx cancer.

    Several clinical studies analyze axillary treatment in women with early-stage breast cancer because of changes in the indication for axillary lymph node dissection. The aim of the study is to analyze the impact of axillary radiotherapy in disease-free and overall survival in women with early breast cancer treated with lumpectomy. Retrospective study in women with initial stages of breast carcinoma treated by lumpectomy. A comparative analysis of high-risk women with axillary lymph node involvement who received axillary radiotherapy with the group of women with low risk without radiotherapy was performed. Logistic regression was used to determine factors influencing survival and lymphedema onset. A total of 541 women were included in the study: 384 patients (71%) without axillary lymph node involvement and 157 women (29%) with 1-3 axillary lymph node involvement. Patients with axillary radiotherapy had a higher number of metastatic lymph node compared to non-irradiated (1.6±0.7 vs. 1.4±0.6, P=.02). The group of women with axillary lymph node involvement and radiotherapy showed an overall and disease-free survival at 10 years similar to that obtained in patients without irradiation (89.7% and 77.2%, respectively). 3 lymph nodes involved multiplied by more than 7 times the risk of death (HR=7.20; 95% CI: 1.36 to 38.12). The multivariate analysis showed axillary lymph node dissection as the only variable associated with the development of lymphedema. The incidence of axillary relapse on stage I and II breast cancer is rare. In these patients axillary radiotherapy does not improve overall survival, but contributes to regional control in those patients with risk factors. Copyright © 2016 AEC.

    Localized oesophageal and gastric cancers have a poor prognosis. In oesophageal cancer, external radiotherapy combined with concomitant chemotherapy is accepted as part of the therapeutic armamentarium in a curative intent in the preoperative setting for resectable tumours; or without surgery in inoperable patients or non-resectable tumours due to wide local and/or regional extension. Data from the literature show conflicting results with no clinical evidence in favour of either a unique dose protocol or consensual target volume definition in the setting of exclusive chemoradiation. In the preoperative setting, chemoradiotherapy has become the standard in oesophageal cancer, even though there is no evidence that surgery may be beneficial in locally advanced tumours that respond to radiotherapy and chemotherapy. The main cause of failure after exclusive chemoradiotherapy in oesophageal cancer is locoregional relapse suggesting that doses and volumes usually considered may be inadequate. In gastric cancer, radiotherapy may be indicated postoperatively in patients with resected tumours that include less than D2 lymph node dissection or in the absence of perioperative chemotherapy. Preoperative chemoradiotherapy in gastric cancers is still under investigation. The evolving techniques of external radiotherapy, such as image-guided radiotherapy (IMRT) and volumetric modulated arctherapy (VMAT) have reduced the volume of lung and heart exposed to radiation, which seems to have diminished radiotherapy-related morbi-mortality rates. Given this, quality assurance for radiotherapy and protocols for radiotherapy delivery must be better standardized. This article on the indications for radiotherapy and the techniques used in oesophageal and gastric cancers is included in a special issue dedicated to national recommendations from the French society of radiation oncology (SFRO) on radiotherapy indications, planning, dose prescription, and techniques of radiotherapy delivery.

    There is a lack of data from phase III randomized studies to support an ideal approach for locally advanced oral cavity cancer patients. In general, surgery, radiotherapy and chemotherapy are valid treatment options, and combined approach is usually indicated given poor clinical outcomes with single modality therapy. The aim of this study is to review the current status and future perspectives of induction chemotherapy for locally advanced oral cavity cancer patients.

    The author report a study aimed at assessing the tolerance and efficiency of a technique which has been used for some years and which comprises the implantation of Gliadel wafers in the operative bed before performing a concomitant radiotherapy and chemotherapy with temozolomide, followed by six adjuvant chemotherapy sessions with the Stupp protocol. Four women and seven men have been implanted with Gliadel wafers. Only one patient did not have the concomitant chemo-radiotherapy. The global survival and global survival without progression have been assessed. Even though the obtained results are encouraging, the concomitant chemo-radiotherapy had to be stopped for three patients due to haematological consequences. Short communication

    The main stay of treatment for head and neck cancer patients with advanced disease has been chemotherapy with Cisplatin/5-FU and simultaneous applied radiotherapy. With this multimodality treatment including radical surgery after two cycles of neoadjuvant chemotherapy and 40 Gy radiotherapy we reported 60% complete remission after 5 years for patients with stage III/IV of head and neck cancer. Paclitaxel, a new plant product, has demonstrated significant antineoplastic activity in head and neck tumors (ECOG-Study: 40% RR). Therefore we performed a trial with Taxol/5-FU and simultaneous radiation in a neoadjuvant and postoperative adjuvant setting of stage III/IV squamous cell carcinoma of the head and neck with pre-existent contraindication against Cisplatin. Patients and Methods: 30 patients with a primarily inoperable stage III/IV of SCC of the head and neck were enrolled to receive day 1 and 29 Taxol 175 mg/m{sup 2} as a 3-hour-infusion, followed by 120-hour-cvi of 1000 mg/m{sup 2}/d 5-FU. Locally irradiation was given ad 40 Gy (2 Gy/d/day 1-26). Radical surgery followed about day 56. Postoperatively patients received again 2 cycles of Taxol/5-FU and simultaneous irradiation with 30 Gy. Results: So far 30 patients were treated and all patients reached a CR after complete treatment, ongoing for 23/30 patients for 6 till 34 months: 4 patients developed a second neoplasia, and 3 patients gloved a local relapse. The principal toxicity was moderate (neutropenia, peripheral neuropathy, arthralgia/myalgia) and sensible with supportive care (e.g. PEG). Conclusions: The results suggest that the treatment of SCC of the head and neck with Taxol/5-FU and simultaneous radiation and radical surgery is a highly effective schedule and comparable with the treatment with Cisplatin/5-FU.

    Objective Nasal-type natural kil er/T-cel lymphoma of Waldeyer’s ring (WR-NK/TL) has dif erent clinico-pathological characteristics from those of other subtypes of NK/T lymphoma; thus, the optimal treatment remains unclear. To find a more ef ective treatment model for WR-NK/TL, we conducted a single-center study of concurrent radiochemotherapy. Methods Forty-five patients with newly diagnosed stage IE to IIE WR-NKTL were randomly divided into two groups. The 23 cases in the concurrent radiochemotherapy group were treated with three-dimensional conformal radiotherapy (48–52 Gy) and 2 courses of DICE (dexamethasone, ifosfamide, cisplatin, and etoposide) synchronous chemotherapy. The 22 cases in the radiotherapy group only received three-dimen-sional conformal radiotherapy (50–54 Gy). The primary end points were overal survival (OS), progression-free survival (PFS), and toxicity. Results The 1-, 3-, and 4-year OS and PFS rates were 95.5%, 65.6%, and 45.9%, and 86.4%, 56.0%, and 46.7% in the radiotherapy group, and 100%, 88.5%, and 88.5%, and 100%, 82.0%, and 73.8% in the concurrent radiochemotherapy group, respectively. The OS (P = 0.0477) and PFS rates (P = 0.0488) were higher in the concurrent radiochemotherapy group than in the radiotherapy group. The overal re-sponse rate was 100% in both the radiotherapy group [complete response (CR), 18 cases] and concurrent radiochemotherapy group (CR, 22 cases). The concurrent radiochemotherapy group had more severe side ef ects, especial y grade 3 + 4 events, such as leukopenia, anorexia, and stomatitis. However, side ef ects benefiting from excel ent oral care were endurable. Conclusion Radiotherapy plus concurrent DICE chemotherapy may be an ef ective and safe compre-hensive treatment for patients with WR-NKTL.

    Background Endometrial adenocarcinoma (womb cancer) is a malignant growth of the lining (endometrium) of the womb (uterus). It is distinct from sarcomas (tumours of the uterine muscle). Survival depends the risk of microscopic metastases after surgery. Adjuvant (postoperative) chemotherapy improves survival from some other adenocarcinomas, and there is evidence that endometrial cancer is sensitive to cytotoxic therapy. This systematic review examines the effect of chemotherapy on survival after hysterectomy for endometrial cancer. Objectives To assess efficacy of adjuvant (postoperative) chemotherapy for endometrial cancer. Search methods We searched the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library 2010, Issue 3), MEDLINE and EMBASE up to August 2010, registers of clinical trials, abstracts of scientific meetings, reference lists of included studies and contacted experts in the field. Selection criteria Randomised controlled trials (RCTs) comparing adjuvant chemotherapy with any other adjuvant treatment or no other treatment. Data collection and analysis We used a random-effects meta-analysis to assess hazard ratios (HR) for overall and progression-free survival and risk ratios (RR) to compare death rates and site of initial relapse. Main results Five RCTs compared no additional treatment with additional chemotherapy after hysterectomy and radiotherapy. Four trials compared platinum based combination chemotherapy directly with radiotherapy. Indiscriminate pooling of survival data from 2197 women shows a significant overall survival advantage from adjuvant chemotherapy (RR (95% CI) = 0.88 (0.79 to 0.99)). Sensitivity analysis focused on trials of modern platinum based chemotherapy regimens and found the relative risk of death to be 0.85 ((0.76 to 0.96); number needed to treat for an additional beneficial outcome (NNT) = 25; absolute risk reduction = 4% (1% to 8%)). The HR for overall survival is 0.74 (0.64 to 0.89), significantly

    Antineoplastic chemotherapy (CT) represents the systemic treatment of malignant tumors. It can be used alone or combined with surgery and / or radiotherapy. The cytotoxic agents used in chemotherapy work on both cancerous cells and noncancerous cells of the body, generally resulting in high toxicity. The biological aggressiveness of chemotherapy particularly affects rapidly replicating cells, such as those of the digestive tract, resulting in adverse effects that impair food intake, leading to compromised nutritional status and which may lead to cachexia. The main toxic effects of chemotherapy in the gastrointestinal tract include nausea, vomiting -these are the most frequent- constipation, diarrhea, xerostomia, mucositis, dysphagia and anorexia. Given the high frequency of such effects, nutritional intervention should be an integral part of cancer treatment, to maintain and/or improve the patient's nutritional status and reduce or minimize the side effects caused by treatment. Accordingly, the goal of this study is to review dietetic conduct in the process of caring for patients undergoing cancer chemotherapy.

    The optimal antiretroviral therapy (ART) regimen for human immunodeficiency virus (HIV)–infected patients with cancer remains unknown, as clinical trials are lacking and published data are insufficient to guide recommendations. When concomitant use of chemotherapy and ART is anticipated, overlap of toxic effects and drug–drug interactions between chemotherapy and ART may alter the optimal choice of ART. Prospective studies are urgently needed to further define the toxic effects of combined chemotherapy and ART in HIV-positive cancer patients. Such studies should aid the development of guidelines for treatment of this population. For now, clinicians should individualize decisions regarding treatment of HIV according to clinical and laboratory findings, cancer treatment plan (chemotherapy, radiotherapy, or surgery), liver or renal disease, potential adverse drug effects (eg, rash, gastrointestinal intolerance, bone marrow suppression), and patient preference. This review focuses on what infectious disease specialists need to know to select the most appropriate ART regimens for patients receiving chemotherapy. PMID:24642555

    Full Text Available Abstract Background This study evaluated the feasibility, toxicity, response rate and survival of neoadjuvant superselective intra-arterial infusion of high dose carboplatin in advanced head and neck cancer. Methods Forty-six patients with primary head and neck squamous cell carcinoma received 3 cycles of intra-arterial carboplatin (300 to 350 mg/m2 per cycle every 2 weeks, followed by radiotherapy or surgery plus radiotherapy. Results No complications or severe toxicity occurred. Sixteen patients (35% were complete responders, 20 (43% partial responders while 10 (22% did not respond to treatment. After completion of the multimodality treatment, 38/46 patients (83% were complete responders. After a 5-year follow-up period, 18/46 patients (39% are alive and disease-free, 3 (6,5% have died of a second primary tumor and 25 (54,5% have died of the disease. Conclusion Intra-arterial carboplatin induction chemotherapy is a safe, well-tolerated technique that discriminates between responders and non-responders and so may have prognostic significance in planning further integrated treatments aimed to organ preservation for advanced head and neck carcinomas.

    A postsurgical "stage-based" protocol for ependymoma was designed. Children were given: (1) focal hyperfractionated radiotherapy (HFRT) if with no evidence of disease (NED), or (2) 4 courses with VEC followed by HFRT for residual disease (ED). HFRT dose was 70.4 Gy (1.1 Gy/fraction b.i.d.); VEC consisted of VCR 1.5 mg/m2 1/w, VP16 100 mg/m2/day x 3, CTX 3 g/m2 d 1. When feasible, second-look surgery was recommended. Sixty-three consecutive children were enrolled: 46 NED, 17 ED; the tumor was infratentorial in 47 and supratentorial in 16, with spinal metastasis in 1. Of NED patients, 35 of 46 have been treated with HFRT; 8 received conventionally fractionated radiotherapy, and 3 received no treatment. Of the 17 ED patients, 9 received VEC + HFRT; violations due to postsurgical morbidity were as follows: HFRT only (2), conventionally fractionated radiotherapy (3) + VEC (2), and no therapy (1). Objective responses to VEC were seen in 54%; objective responses to RT were seen in 75%. Overall survival and progression-free survival at 5 years for all 63 children were 75% and 56%, respectively; for the NED subgroup, 82% and 65%; and for the ED subgroup, 61% and 35%, respectively. All histologies were centrally reviewed. At multivariate analysis, grading, age, and site proved significant for prognosis. HFRT, despite the high total dose adopted, did not change the prognosis of childhood ependymoma as compared to historical series: New radiotherapeutic approaches are needed to improve local control. Future ependymoma strategies should consider grading when stratifying treatment indications.

    Surgery for head and neck squamous cell carcinoma can alter speech, swallowing, and cosmoses. Recent tendency is to avoid mutilating surgery unless the tumour is aggressive or resistant to chemotherapy and or radiotherapy. Functional surgery is being widely employed, and for example it may vary between conventional partial surgery and endoscopic laser surgery for small sized vocal cord cancers. Various new reconstructive procedures have been developed to help early functional restoration. Loco-regional flaps can be used to replace gums and avoid dental extractions. Free flaps with micro-vascular anastomosis can be employed for immediate reconstruction of extensive surgical defects involving pharyngeal wall, tongue, mandible and mid-face to restore better function and cosmoses. Few recently developed techniques can be also employed in selected cases of laryngo-pharyngeal cancers to avoid permanent laryngeal mutilation. Another goal of functional surgery is to decrease the postoperative radiotherapy or chemo-radiotherapy sequelae, and obtain successful postoperative functional rehabilitation.

    Background Reliable early prediction response to therapy and time-to-progression (TTP) remain an important goal of high-grade gliomas (HGGs) research.Proton magnetic resonance spectroscopy (1H-MRS) has been applied with variable success in clinical application,and we hypothesize that 1H-MRS in predictive value should perform well as a marker of TTP in patients treated with radiotherapy (RT) after surgery.Methods 1H-MRS was performed before surgery on 25 patients who had undergone resection of HGGs; then the ratios of lipid/creatine (Lip/Cr) and myo-inositol/creatine (ml/Cr) were determined in the solid tumor.RT response was classified as follows:complete resolution (CR),partial response (PR),stable disease (SD),and progressive disease (PD) by comparison of pre-treatment and post-radiotherapy scans.TTP was defined at the time to radiographic progression by MacDonald criteria.Correlation was evaluated between the ratios of Lip/Cr,ml/Cr and treatment response,TTP.The chi-square test and Pearson correlation test were used for data analyses.Results Multivariate analysis revealed that the prognostic value of spectroscopic variables was independent of age,sex,WHO histologic grade,extent of surgery,and Karnofsky score (KPS).The correlation between the ratios of lipid/Cr and TTP was significant (r=0.894,P=0.000),and between the ratios of ml/Cr and TTP was also significant (r=0.891,P=0.000).As predicted,RT response correlated significantly with TTP (r=0.59,P=0.002):median TTP was 49.9 days for patients with PD compared with 202.7 days for SD,208.0 days for PR,and 234.5 days for CR.Conclusion The ratios of Lip/Cr and ml/Cr of the solid tumor region before surgery could provide important information in predicting RT response and TTP in patients with HGGs treated by radiation alone after surgery.

    Data suggest selective internal radiotherapy (SIRT) in third-line or subsequent therapy for metastatic colorectal cancer has clinical benefit in patients with colorectal liver metastases with liver-dominant disease after chemotherapy. The FOXFIRE, SIRFLOX, and FOXFIRE-Global randomised studies evaluated the efficacy of combining first-line chemotherapy with SIRT using yttrium-90 resin microspheres in patients with metastatic colorectal cancer with liver metastases. The studies were designed for combined analysis of overall survival. FOXFIRE, SIRFLOX, and FOXFIRE-Global were randomised, phase 3 trials done in hospitals and specialist liver centres in 14 countries worldwide (Australia, Belgium, France, Germany, Israel, Italy, New Zealand, Portugal, South Korea, Singapore, Spain, Taiwan, the UK, and the USA). Chemotherapy-naive patients with metastatic colorectal cancer (WHO performance status 0 or 1) with liver metastases not suitable for curative resection or ablation were randomly assigned (1:1) to either oxaliplatin-based chemotherapy (FOLFOX: leucovorin, fluorouracil, and oxaliplatin) or FOLFOX plus single treatment SIRT concurrent with cycle 1 or 2 of chemotherapy. In FOXFIRE, FOLFOX chemotherapy was OxMdG (oxaliplatin modified de Gramont chemotherapy; 85 mg/m(2) oxaliplatin infusion over 2 h, L-leucovorin 175 mg or D,L-leucovorin 350 mg infusion over 2 h, and 400 mg/m(2) bolus fluorouracil followed by a 2400 mg/m(2) continuous fluorouracil infusion over 46 h). In SIRFLOX and FOXFIRE-Global, FOLFOX chemotherapy was modified FOLFOX6 (85 mg/m(2) oxaliplatin infusion over 2 h, 200 mg leucovorin, and 400 mg/m(2) bolus fluorouracil followed by a 2400 mg/m(2) continuous fluorouracil infusion over 46 h). Randomisation was done by central minimisation with four factors: presence of extrahepatic metastases, tumour involvement of the liver, planned use of a biological agent, and investigational centre.

    A 61-year-old man underwent amputation of the rectum for advanced lower rectal cancer in April 2005. UFT-E granules were administered orally daily at 400 mg/body/day following surgery. He developed perineal pain and perineal discharges following an increase the CEA level in April 2006. PET revealed a tumor in the perineum and multiple lung metastases. Chemotherapy with mFOLFOX 6 for 8 courses and FOLFIRI 2 for 4 courses were administered since July in 2006. Although CT revealed a the reduction in multiple lung metastases, CEA was increased to over a maximum 109, high fever continued and the pinealtumor was enlarged in December 2006. The patient underwent resection of the perinealmass, but he developed perinealsevere pain and perinealdischarge. So radiotherapy of the pelvic region was given at a total dose of 40 Gy(given 2 Gy each fragment)followed by administration of FOLFIRI 2 for 12 courses. After chemoradiotherapy, the CEA level was remarkably decreased. PET could not detect any mass in lung fields and revealed a little accumulation in the pelvic region. Chemotherapy with FOLFIRI 2 is administered monthly now, and the CEA level has been within the normal range since July of 2007. The pineal pain and pineal discharge disappeared, so the quality of life has improved dramatically.

    Breast conserving surgery (BCS) followed by chemotherapy (CT{sub x}.) and radiation therapy (RT) is widely performed for the treatment of early breast cancer. This retrospective study was undertaken to evaluate our interim results in terms of failure patterns, survival and relative risk factors. From January 1999 through December 2003, 129 patients diagnosed with invasive breast cancer and treated with BCS followed by RT were subject to retrospective review. The median age of the patients was 45 years (age distribution, 27 {approx} 76 years). The proportions of patients according to their tumor, nodes, and metastases (TNM) stage were 65 (50.4%) in stage I, 41 (31.7%) in stage IIa, 13 (10.1%) in stage IIb, 9 (7.0%) in stage III, and 1 patient (0.8%) in stage IIIc. For 32 patients (24.8%), axillary node metastasis was found after dissection, BCS consisted of quadrantectomy in 115 patients (89.1%) and lumpectomy in 14 patients (10.6%). Axillary node dissection at axillary level I and II was performed for 120 patients (93%). For 7 patients (5.4%), only sentinel node dissection was performed with BCS. For 2 patients (1.6%) axillary dissection of any type was not performed. Postoperative RT was given with 6 MV X-rays. A tumor dose of 50.4 Gy was delivered to the entire breast area using a tangential field with a wedge compensator. An additional dose of 9 {approx} 16 Gy was given to the primary tumor bed areas with electron beams. In 30 patients (23.3%), RT was delivered to the supraclavicular node. Most patients had adjuvant CT{sub x}. with 4 {approx} 6 cycles of CMF (cyclophosphamide, methotrexate, 5-fluorouracil) regimens. The median follow-up period was 50 months (range: 17 {approx} 93 months). The actuarial 5 year survival rate (5Y-OSR) was 96.9%, and the 5 year disease free survival rate (5Y-DFSR) was 93.7%. Local recurrences were noted in 2 patients (true: 2, regional node: 1) as the first sign of recurrence at a mean time of 29.3 months after surgery. Five

    Full Text Available Abstract Background Results of high-dose chemo-radiotherapy (CRT, using the treatment schedules of EORTC study 08972/22973 or radiotherapy (RT alone were analyzed among all patients (pts with Non Small Cell Lung Cancer (NSCLC treated with curative intent in our department from 1995–2004. Material Included are 131 pts with medically inoperable or with irresectable NSCLC (TNM stage I:15 pts, IIB:15 pts, IIIA:57 pts, IIIB:43 pts, X:1 pt. Treatment Group I: Concomitant CRT: 66 Gy/2.75 Gy/24 fractions (fx/33 days combined with daily administration of cisplatin 6 mg/m2: 56 pts (standard. Group II: Sequential CRT: two courses of a 21-day schedule of chemotherapy (gemcitabin 1250 mg/m2 d1, cisplatin 75 mg/m2 d2 followed by 66 Gy/2.75 Gy/24 fx/33 days without daily cisplatin: 26 pts. Group III: RT: 66 Gy/2.75 Gy/24 fx/33 days or 60 Gy/3 Gy/20 fx/26 days: 49 pts. Results The 1, 2, and 5 year actuarial overall survival (OS were 46%, 24%, and 15%, respectively. At multivariate analysis the only factor with a significantly positive influence on OS was treatment with chemo-radiation (P = 0.024 (1-, 2-, and 5-yr OS 56%, 30% and 22% respectively. The incidence of local recurrence was 36%, the incidence of distant metastases 46%. Late complications grade 3 were seen in 21 pts and grade 4 in 4 patients. One patient had a lethal complication (oesophageal. For 32 patients insufficient data were available to assess late complications. Conclusion In this study we were able to reproduce the results of EORTC trial 08972/22973 in a non-selected patient population outside of the setting of a randomised trial. Radiotherapy (66 Gy/24 fx/33 days combined with either concomitant daily low dose cisplatin or with two neo-adjuvant courses of gemcitabin and cisplatin are effective treatments for patients with locally advanced Non-Small Cell Lung Cancer. The concomitant schedule is also suitable for elderly people with co-morbidity.

    The objective of this work was to assess the incidence of radiological changes compatible with radiation-induced lung damage as determined by computed tomography (CT), and subsequently calculate the dose effect factors (DEF) for specified chemotherapeutic regimens. Radiation treatments were administered once daily, 5 days-per-week. Six clinical protocols were evaluated: ABVD (adriamycin, bleomycin, vincristine, and DTIC) followed by 35 Gy in 20 fractions; MOPP (nitrogen mustard, vincristine, procarbazine, and prednisone) followed by 35 Gy in 20; MOPP/ABVD followed by 35 Gy in 20; CAV (cyclophosphamide, adriamycin, and vincristine) followed by 25 Gy in 10; and 5-FU (5-fluorouracil) concurrent with either 50-52 Gy in 20-21 or 30-36 Gy in 10-15 fractions. CT examinations were taken before and at predetermined intervals following radiotherapy. CT evidence for the development of radiation-induced damage was defined as an increase in lung density within the irradiated volume. The radiation dose to lung was calculated using a CT-based algorithm to account for tissue inhomogeneities. Different fractionation schedules were converted using two isoeffect models, the estimated single dose (ED) and the normalized total dose (NTD). The actuarial incidence of radiological pneumonitis was 71% for the ABVD, 49% for MOPP, 52% for MOPP/ABVD, 67% for CAV, 73% for 5-FU radical, and 58% for 5-FU palliative protocols. Depending on the isoeffect model selected and the method of analysis, the DEF was 1.11-1.14 for the ABVD, 0.96-0.97 for the MOPP, 0.96-1.02 for the MOPP/ABVD, 1.03-1.10 for the CAV, 0.74-0.79 for the 5-FU radical, and 0.94 for the 5-FU palliative protocols. DEF were measured by comparing the incidence of CT-observed lung damage in patients receiving chemotherapy and radiotherapy to those receiving radiotherapy alone. The addition of ABVD or CAV appeared to reduce the tolerance of lung to radiation. 40 refs., 3 figs., 3 tabs.

    2010-01-01

    Full Text Available There have been recent reports on the expediency of applying postoperative hypofractionated accelerated radiotherapy (RT regimens in patients who have undergone breast-sparing surgery. The concept of accelerated hypofractionation (AH includes daily high-dose radiation for a shorter total period of time. In most radiologists’ opinion, the AH RT regimen may be as effective as more conventional treatments that use lower daily radiation doses for a longer period. The appeal of this method is that shorter treatment provides more convenience for patients. By taking into account the fact that the α/β ratio for intact breast tissues is about 3.5 Gy, larger fraction RT regi- mens are likely to be more effective, which will reduce the frequency of recurrences as compared with conventional therapy approaches without increasing the incidence of postradiation intact tissue damage.

    Peritoneal carcinomatosis (PC) has been traditionally considered a terminal disease with median survivals reported in the literature of 6 to 12 months. Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (HIPEC) are playing an ever increasing role in the treatment of these patients. Excellent results have been achieved in well-selected patients but there is a very steep learning curve when starting a new program. A program for peritoneal surface malignancies in which patients with PC of gastrointestinal or gynecological origin were treated using multimodality therapy with combinations of systemic therapy, cytoreductive surgery (CRS), and HIPEC was initiated in December 2007 at "Hospital Regional de Alta Especialidad de Oaxaca," Mexico. We present the results of our initial experience. From December 2007 to February 2011, 26 patients were treated with CRS and HIPEC. There were 21 female patients. Most common indication (46%) was recurrent ovarian cancer. Mean duration of surgery was 260 minutes. Mean Peritoneal Cancer Index was 9. Twenty-three (88.5%) patients had a complete cytoreduction. Major morbidity and mortality rates were 19.5 and 3.8 per cent, respectively. Mean hospital stay was 8 days. At a mean follow-up of 20 months, median survival has not been reached. Rigorous preoperative workup, strict selection criteria, and mentoring from an experienced cytoreductive surgeon are mandatory and extremely important when starting a center for PC.

    Full Text Available Ewing′s sarcoma constitutes three per cent of all pediatric malignancies. Ewing′s sarcoma has generally been more responsive to chemotherapy than adult-type sarcomas, and chemotherapy is now recommended for all patients with this disease. It is essential to integrate local control measures in the form of surgery and/or radiotherapy at the appropriate time, along with chemotherapy to eradicate the disease. This approach has improved the survival substantially to the tune of 70% in localized disease, although outcome for metastatic disease remains dismal. Newer therapeutic approaches are required to improve outcome for metastatic and recurrent or refractory Ewing′s sarcoma in organized co-operative group trials.

    Purpose: This multicenter retrospective study was designed to evaluate the prognostic role of interim fluorodeoxyglucose-labeled positron emission tomography (i-FDG-PET) in a cohort of patients affected with early-stage Hodgkin lymphoma (HL) treated initially with adriamycin, bleomycin, vinblastine, dacarbazine (ABVD) chemotherapy followed by radiation therapy, and to assess the role of chemotherapy continuation plus radiation therapy for i-FDG-PET-positive patients. Methods and Materials: Data from 257 patients were retrieved from 4 hematology and radiation oncology departments. Inclusion criteria were stage I to IIAB HL, “intention-to-treat” AVBD plus radiation therapy, and FDG-PET at diagnosis and after the first 2 ABVD cycles. All i-FDG-PET scans underwent blinded local review by using the Deauville 5-point scoring system; patients were stratified as negative or positive using 2 Deauville score cutoff values, ≥3 or ≥4. Results: Median follow-up time was 56 months (range: 9-163 months); 5-year overall survival (OS) and disease-specific survival (DSS) for the whole cohort were 97.5% and 98.3%, respectively. Five-year progression-free survival (PFS) was 95.6%. After i-FDG-PET revision, 43 of 257 patients (16.7%) had a positive i-FDG-PET (Deauville scores: 3-5). Five-year PFS rates for i-FDG-PET-negative and i-FDG-PET-positive patients were 98.1% and 83.7%, respectively, if using a Deauville score cutoff of 3, and 97.7% and 78.6%, respectively, if using a cutoff of 4 (P=.0001). Five-year OS for i-FDG-PET-negative and i-FDG-PET-positive patients was 98.5% and 93.0%, respectively, if using a cutoff of 3, and 98.6% and 89.3%, respectively, if using a cutoff of 4 (P=.029 and P=.002). At univariate regression analysis, i-FDG-PET positivity was associated with worse OS and PFS. At multivariate analysis, performed only for PFS, i-FDG-PET positivity confirmed its negative impact (P=.002). Conclusions: i-FDG-PET is prognostic for PFS and OS in early-stage HL

    There are well-known side effects of chemotherapy and radiotherapy that are mainly related to the toxicity and impaired function of vital organs; however, the induction by these therapies of expression of several pro-metastatic factors in various tissues and organs that in toto create a pro-metastatic microenvironment is still, surprisingly, not widely acknowledged. In this review, we support the novel concept that toxic damage in various organs leads to upregulation in "bystander" tissues of several factors such as chemokines, growth factors, alarmines, and bioactive phosphosphingolipids, which attract circulating normal stem cells for regeneration but unfortunately also provide chemotactic signals to cancer cells that survived the initial treatment. We propose that this mechanism plays an important role in the metastasis of cancer cells to organs such as bones, lungs, and liver, which are highly susceptible to chemotherapeutic agents as well as ionizing irradiation. This problem indicates the need to develop efficient anti-metastatic drugs that will work in combination with, or follow, standard therapies in order to prevent the possibility of therapy-induced spread of tumor cells.

    Testicular stage I seminoma has a remarkable cure rate with orchiectomy alone. The benefit of adjuvant therapy is questionable, and a direct comparison with active surveillance is lacking. We performed a meta-analysis to evaluate the benefit of adjuvant radiotherapy (RT) or chemotherapy (CT) compared with surveillance alone on relapse-free survival (RFS), overall survival (OS), and noncancer-related mortality in patients with stage I seminoma. We performed a systematic search of PubMed, EMBASE, Web of Science, SCOPUS, and the Cochrane Register of Controlled Trials. Meta-analysis was performed using the fixed- or random-effects models. The primary endpoint was 5-year RFS, and secondary endpoints were 5-year OS and 5-year noncancer-related mortality, reported as odds ratios (ORs) and 95% confidence intervals (CIs). A total of 13 trials (11 retrospective and 2 prospective cohort series), including 12,075 patients with stage I seminoma, were analyzed. The relapse rates were 3.9% versus 14.8% in the adjuvant therapy and surveillance arms, respectively. Overall, adjuvant therapy significantly improved 5-year RFS (OR, 0.17; 95% CI, 0.1-0.29; P seminoma. However, they do not increase OS or noncancer-related mortality. Both treatment options can be offered to patients with stage I seminoma, taking into consideration the side effects and high cure rate of testicular cancer at relapse. Copyright © 2015 Elsevier Inc.

    Background: Legislation preventing smoking in public places was introduced in England in July 2007. Since then, smoke-free policies have been extended to the majority of hospitals including those providing cancer therapies. Whilst studies have been conducted on the impact and effectiveness of hospital smoke-free policy in the UK and other countries, there have not been any studies with a focus on cancer care providers. Cancer patients are a priority group for smoking cessation and support and this study aimed to examine implementation of the National Institute Clinical Excellence (NICE) guidance (PH48) in acute cancer care trusts in the UK. Methods: Participants were recruited from UK radiotherapy and chemotherapy departments (total 80 sites, 65 organisations) and asked to complete a 15 min online questionnaire exploring the implementation of NICE guidance at their hospital site. Results: Considerable variability in implementation of the NICE guidance was observed. A total of 79.1% trusts were smoke-free in theory; however, only 18.6% were described as smoke-free in practice. Areas of improvement were identified in information and support for patients and staff including in Nicotine Replacement Therapy (NRT) provision, staff training and clarity on e-cigarette policies. Conclusions: While some trusts have effective smoke-free policies and provide valuable cessation support services for patients, improvements are required to ensure that all sites fully adopt the NICE guidance.

    From 1972 to 1976, 102 patients with stages I-IIIA Hodgkin's disease (HD) were treated by chemotherapy with cyclophosphamide, vinblastine, procarbazine and prednisone (CVPP: two courses) associated with extended field radiotherapy. Staging included neither laparotomy nor splenectomy (clinical staging). Treatment included neither splenic irradiation nor maintenance therapy. Complete remission was achieved for 98 patients and 11 of them recurred up to 94 months after treatment. Median follow-up of this controlled study is 13 years. Disease free survival (DFS) is 87% at 6 years and 84% at 10 and 15 years. Overall survival is 77% at 10 and 74% at 15 years. Disease specific survival is better (91% at 10 and 87% at 15 years) since only 38% (10/26) deaths were due to HD. The other deaths (16/26) with no evidence of HD were due to second cancer and intercurrent disease. Prognostic analysis of DFS by log-rank test gives significance to the following factors: contiguous extra-nodal involvement (P = 0.008), more than 3 involved sites (P 0.01), signs of compression (P = 0.02), clinical stage IIIA (P = 0.03), infradiaphragmatic stages I-II (P 0.04). The potential risk of secondary cancer is difficult to assess.

    Tongue strength is reduced in patients treated with chemoradiotherapy for oral/oropharyngeal cancer. Tongue strengthening protocols have resulted in improved lingual strength and swallowing in healthy individuals, as well as in patients following a neurological event. However, no studies have examined the efficacy of tongue strengthening exercises on tongue strength, swallowing, and quality of life (QOL; Head and Neck Cancer Inventory) in patients treated with chemoradiotherapy. A randomized clinical trial examined the effects of a tongue strengthening programme paired with traditional exercises vs. traditional exercises alone. Dependent variables included tongue strength, swallowing, and QOL in a group of patients with oral and oropharyngeal cancer treated with primary radiotherapy with or without chemotherapy. Differences with regard to tongue strength and oropharyngeal swallow efficiency (OPSE) were not observed within or between groups. QOL in the eating and speech domains improved following treatment in both groups. However, the experimental group demonstrated greater impairment in QOL in the social disruption domain following treatment, whereas the control group demonstrated a slight improvement in functioning. Tongue strengthening did not yield a statistically significant improvement in either tongue strength or swallowing measures in this patient cohort. Patient compliance and treatment timing may be factors underlying these outcomes.

    Full Text Available Abstract Background The aim of this study was to assess the results of curative surgery with and without radiotherapy in patients with T1-2N0-1 oral tongue squamous cell carcinoma (OSCC and to evaluate survival and prognostic factors. Methods Retrospective analysis of 86 patients with T1-2N0-1 OSCC who received surgery between January 2000 and December 2006. Fourteen patients (16.3% received postoperative radiotherapy (PORT. Patient characteristics, tumor characteristics, treatment modality, failure patterns, and survival rates were analyzed. Results The median follow-up was 45 months. The five-year overall survival (OS and disease-free survival (DFS rates were 80.8% and 80.2%, respectively. Higher tumor grade and invasion depth ≥ 0.5 cm were the significant prognostic factors affecting five-year OS and DFS (OS rate; 65% vs. 91%, p = 0.001 for grade; 66% vs. 92%, p = 0.01 for invasion depth: DFS rate; 69% vs. 88%, p = 0.005 for grade; 66% vs. 92%, p = 0.013 for invasion depth. In the risk group, there was no local failure in patients with postoperative radiotherapy. Conclusions In T1-2N0-1 OSCC, factors that affected prognosis after primary surgery were higher tumor grade and deep invasion depth over 0.5 cm. Postoperative radiotherapy should be considered in early oral tongue cancer patients with these high-risk pathologic features.

    A man in his 60s was admitted for the treatment of advanced cervical esophageal cancer with metastasis to the lymph nodes and advanced tongue cancer with metastasis to the lymph nodes. Esophageal cancer was suspected to have invaded the trachea. The tongue cancer was located on the left side and had invaded beyond the median line of the tongue. Both cancers were pathologically diagnosed as squamous cell carcinomas. Therefore, it was determined that pharyngo-laryngo- esophagectomy and total glossectomy were required prior to the treatment. However, after 2 courses of docetaxel/cisplatin/ 5-FU combined induction chemotherapy, both cancers remarkably decreased; consequently, an esophagectomy to preserve laryngeal function and partial glossectomy could be performed simultaneously. The patient is well without recurrence 1 year post-surgery.

    The overexpression of mutant p53 stimulates serum p53 antibody production in patients with colorectal carcinoma even in superficial tumors. Although the short-term perioperative monitoring of serum p53 antibody titers is reported to be useful in predicting tumor recurrence and patient survival in colorectal carcinoma, the clinical utility of the long-term monitoring of serum p53 antibody titers in patients with colorectal cancer remains unknown. Here, we report the 3-year monitoring of serum p53 antibody titers in a 60-year-old man with rectal cancer, clinical stage IV (T2N2M1b, lung and liver metastases), who was treated with chemotherapy and surgery. Screening tests for CEA (29.4 ng/ml), CA19-9 (41.1 U/ml), and serum p53 antibody (2170 U/ml) were positive before treatment. After chemotherapy with mFOLFOX6 + bevacizumab (B-mab), CEA and CA19-9 decreased to the normal range. However, serum p53 antibody titer remained positive (283 U/ml). After low anterior resection, the serum p53 antibody titer still remained positive (63.4 U/ml). Serum p53 antibody titer significantly changed and was associated with treatment response and tumor recurrence. In the last 6 months of the patient's life, serum p53 antibody titer gradually decreased, which possibly reflects the modification of the patient's immune response to p53 antigens.

    Diffuse malignant peritoneal mesothelioma is a rare, aggressive disease. Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) have improved outcomes where systemic chemotherapy has not succeeded. In this study, we compare outcomes of patients treated with mitomycin or carboplatin as perfusate. In this retrospective study, 47 procedures (CRS + HIPEC) were conducted on 44 patients between March 2003 and August 2010 with either mitomycin or carboplatin. χ(2) and Student's t test were used for comparison of clinicopathological variables and Kaplan-Meier curves and log rank test were used to compare overall survival. Median survival of the mitomycin group was 18 months with 1- and 5-year survivals of 72.3 and 27.3 per cent, respectively. Median survival of the carboplatin group was not reached and 1- and 5-year survivals were 89.7 and 62.5 per cent, respectively (P = 0.014). Mean hospital and intensive care unit length of stay was 18.9 and 8.7 days in the mitomycin group and 12.5 and 2.3 days in the carboplatin group (P = 0.0069). Mean number of packed red blood cell units transfused was higher in the mitomycin group compared with the carboplatin group (3.54 vs 0.83, P mitomycin.

    The endometrial carcinoma is the third most common cancer in women. The endometrioid adenocarcinomas represent 75 % to 80 % of the pathologic sub-types, and 90 % of the lesions are stages I or II at diagnosis. The treatment strategies are based upon surgery and radiotherapy, but the respective place of external irradiation and vaginal cuff brachytherapy is not strictly established. The role of the pelvic lymphadenectomy and the role of chemotherapy for aggressive histologies or locally advanced diseases remain also controversial issues. The question 'which radiotherapy for which patient?' is still a current question, however, the answers we will bring do not permit yet to remove all uncertainties. (author)

    Full Text Available To evaluate the effects of age and the clinical response to neoadjuvant chemotherapy (NACT in patients with cervical cancer who received neoadjuvant chemotherapy followed by radical surgery.A total of 1,014 patients with advanced cervical cancer who received NACT followed by radical surgery were retrospectively selected. Patients were divided into young (aged ≤35 years, n = 177 and older (aged >35 years, n = 837 groups. We compared the short-term responses and survival rates between the groups. The five-year disease-free survival (DFS and overall survival (OS rates were stratified by age, NACT response, and FIGO stage.The overall response rate was 86.8% in the young group and 80.9% in the older group. The young patients had an earlier FIGO stage (P<0.001, a higher rate of adenocarcinoma (P = 0.022, and more lymph node metastasis (P = 0.033 than the older patients. The presence of adenocarcinoma as the histological type (P = 0.024 and positive lymph node metastasis (P<0.001 were identified as independent risk factors for survival. When stratified by age and clinical response, young patients with no response to NACT had a worse clinicopathological condition compared with the other subgroups. Compared with non-responders, responders to NACT had a higher five-year DFS rate (80.1% versus 71.8%; P = 0.019 and OS rate (82.6% versus 71.8%; P = 0.003 among the young patients but not among the older patients.Responders to NACT aged 35 years or younger benefitted the most from NACT, while the young non-responders benefitted the least. Age might represent an important factor to consider when performing NACT in patients with cervical cancer.

    Background: Radiotherapy and laser resection are established treatment modalities for early glottic carcinoma. To date, there is no confirmed conclusion which treatment is better for early glottic cancer. The objective of this study was to conduct a meta-analysis to compare the voice outcomes after laser resection (LS) and radiotherapy (RT) of Tis-T1N0M0 glottic carcinoma. Methods: we searched the relevant electronic studies and performed a meta-analysis based on 13 published studies. The Chi-square based I2-statistic test was performed to evaluate possible heterogeneity across the studies. Additionally, random-effects models were used to calculate mean differences with 95% confidence intervals (CIs). Results: Overall, a total of 13 published studies were included in our study, with 368 patients in the RT group and 440 patients in the LS group, respectively. No significant differences in Voice Handicap Index (VHI), jitter and shimmer were found between RT and endoscopic LS among patients with Tis-T1N0M0 glottic carcinoma and T1aN0M0 laryngeal cancer. However, the acoustic voice analysis parameters of Fo values were significantly lower in RT group than that in LS group. Conclusion: The results from this meta-analysis support that the LS has more advantages than RT in terms of voice quality. However, more studies on voice outcome need to validate our findings.

    The aim of this review is to explore the changing utility of radiotherapy in the treatment of patients with glioblastoma over the past 60 years. Together with surgery, radiotherapy has always been the cornerstone of treatment of glioblastoma, but techniques have significantly advanced over this time. The exploration of early two-dimensional techniques, investigation of dose escalation, concomitant chemotherapy and modern techniques, including intensity-modulated radiotherapy, image-guided radiotherapy, and volumetric-modulated arc therapy will be covered. In addition, current controversies including decreasing margin size, re-irradiation, treatment of elderly patients, and novel imaging tracers will be discussed. Future directions including immunotherapy and tumour treating fields are examined. Radiotherapy-based treatments cannot rely solely on advances in chemotherapy or immunotherapy to improve the overall survival of patients with glioblastoma. Radiation oncology needs to continue to develop and improve the delivery, target definition, and dose of radiotherapy to these patients to improve their survival and the toxicity associated with treatment.

    Full Text Available Context: Among patients with locally advanced head and neck squamous cell cancers (LAHNSCC, the prognosis after nonresponse or progression despite induction chemotherapy (IC is dismal, and further treatment is often palliative in intent. Given that nonresponse to chemotherapy could indicate subsequent radioresistance, we intended to assess the outcomes with two different fractionation schemes. Aims: To compare the outcomes of two fractionation schemes- ′standard′ (consisting 3GyX5 daily fractions for 2 consecutive weeks versus ′hybrid′ (6GyX3 fractions on alternate days during the 1 st week, followed by 2GyX5 daily fractions in the 2 nd week. Settings and Design: Prospective randomized controlled two-arm unblinded trial. Materials and Methods: Patients with locally advanced oropharyngeal, laryngeal, and hypopharyngeal cancers treated with a minimum of two cycles of taxane, platinum, and fluorouracil-based IC were eligible if residual disease volume amounted >30 cm 3 . Kaplan-Meier survival curves were compared by the log-rank test. Response rates were compared using the unpaired t-test. Quality of life (QOL was measured via patient reported questionnaires. Results: Of the initially enrolled 51 patients, 45 patients (24 from standard arm, and 21 from the hybrid arm were eligible for analysis. Despite being underpowered to attain statistical significance, there still seemed to be a trend towards improvement in progression-free (Hazard ratio (HR for progression: 0.5966; 95% CI 0.3216-1.1066 and overall survival (HR for death: 0.6062; 95% CI 0.2676-1.3734 with the hybrid arm when compared to the standard arm. Benefits were also observed with regards to response rates and QOL. Rate of complications were similar in both arms. Conclusions: In comparison to the routinely used palliative fractionation scheme of 30 Gray (Gy in 10 fractions (Fr, the use of hybrid fractionation which integrates hypofractionation in the 1 st week, followed by

    Oral mucositis induced by antineoplastic therapy causes wide-range pain and discomfort resulting in decreased quality of life. The present study evaluated the benefits of low intensity laser and 0.12% chlorhexidine gluconate in the prevention of oral mucositis induced by radiation, associated or not with chemotherapy, and considered degrees/severity, time of appearance of the lesions and functional loss. Eighty-four outpatients were considered and 49 were included in this study and divided into two groups: Group 1 received laser treatments in three stages, starting three days before treatment until the end of therapy. Group 2 was instructed to do daily mouth rinses with chlorhexidine gluconate. The prevalence of clinical mucositis was 49%, and of functional mucositis, 28.6%, when the two groups were considered together. This percentage was smaller in the laser group, 44% for the clinical mucositis group and 24% for the functional. The two protocols were well tolerated and showed benefits, mainly from the point of view of functionality, and delayed the onset and development of mucositis. (author)

    Introduction. - Curative therapy for patients with small-cell lung cancer (SCLC) is based on multidrug chemotherapy combinations and radiotherapy. After a long time follow-up, the aim of the study was to evaluate the efficacy and toxicity of sequential chemo-radiotherapy and the effect of prophylactic cranial irradiation (PCI). Methods. - From 1995-2005, 96 patients with SCLC (64 limited-disease [LD], 32 extensive-disease [ED]; median age 61 years [range 39-79]) were treated at our department with varying chemotherapy regimens and sequential mediastinal radiotherapy (50 Gy + 10 Gy boost in case of residual disease after chemotherapy). Afterwards, 15 patients with LD, good general condition and at least partial response after local treatment received PCI (30 Gy). Results. - After a median follow-up of 78.6 months, 20 patients remained alive (20.8%, median survival time 18.2 months). The 2-/5-year overall survival rates were 33.8% and 12.6%, the 2-/5-year loco-regional control rates were 30.3% and 24.5%, respectively. Distant metastases occurred in 43 patients (24 cerebral). Cerebral metastasis occurred in 6.7% and 27.2% of the patients with PCI and without PCI respectively. Only tumor stage showed a statistically significant impact on overall survival and loco-regional control in multivariate analysis. Radiotherapy was well tolerated. Grade 3/4 toxicity occurred in seven patients. Prognosis of patients with SCLC remains poor. Administration of PCI in selected patients bears a decrease in the incidence of cerebral metastases. Alternative chemotherapy schemes as well as irradiation schemes and techniques should be the substance of future randomized trials. (authors)

    A prospective multicenter phase-II trial (12 centers) was performed by the German larynx organ preservation group (DeLOS) to evaluate the effect of induction chemotherapy (ICHT) with paclitaxel/cisplatin (TP), followed by accelerated-hyperfractionated (concomitant boost) radiotherapy (RT) in responders. The trial was focused on larynx preservation, tumor control, survival, salvage surgery and late toxicity in patients with advanced larynx/hypopharynx carcinoma eligible for total laryngectomy (LE). Seventy-one patients (40 larynx, 87.5% St. III, IV; 31 hypopharynx, 93.4% St. III, IV) were enrolled into the study and treated with ICHT (200 mg/m(2) paclitaxel, 100 mg/m(2) cisplatin; day 1, 22) according to the DeLOS protocol. Patients with complete or partial tumor response proceeded to RT (69.9 Gy in 5.5 weeks). Non-responders received a LE followed by postoperative RT (56-70 Gy in 5.5-7 weeks). The response rate to ICHT for larynx cancer was 69.6% (7.1% complete, 62.5% partial response) and for hypopharyngeal cancer was 84.3% (6.9% complete, 77.4% partial response). Overall survival after 36 months was 60.3% (95% CI, 48.4-72.2%), after 42 months was 56.5% (95% CI, 44.2-68.8%). Laryngectomy-free survival was as follows: after 36 months, 43.0% (95% CI, 30.9-55.0%); after 42 months, 41.3% (95% CI, 29.3-53.3%). Both parameters did not show different outcomes after distinguishing larynx from hypopharynx. LE was indicated in 15 non-responders after ICHT. Five of the 15 non-responders refused the laryngectomy. Two of the five received RT instead and had no evidence of disease 42 months after RT. Late toxicity (dysphagia III, IV LENT SOMA score in laryngectomy-free survivors: after 6 months, 1.8%; 12 months, 11.4%; 18 months, 14.5%; 24 months, 8.1%; 36 months, 16%) and salvage surgery (4 pharyngocutaneous fistulas in 27 operations) were tolerable. In a large portion of patients eligible for LE, the larynx could be preserved with satisfying functional outcome. Good

    Full Text Available Purpose: To ascertain factors that could influence the development of ulcers and strictures in the definitive management of squamous cell carcinoma (SCC of esophagus treated with external beam radiotherapy (EBRT, high-dose-rate (HDR intralumenal radiotherapy (ILRT with or without concurrent weekly cisplatin (CDDP @ 35 mg/m2 chemotherapy (CT. Materials and Methods: Between 1990-2005, 244 patients with inoperable SCC of esophagus were identified from our database and grouped into one of the following: those receiving at least 60Gy EBRT (Gp E, n=44; EBRT followed by HDR-ILRT (Gp E+I, n=98; at least 50Gy EBRT with CT (Gp E+C, n=68; EBRT+HDR-ILRT + CT (Gp E+I+C, n=34. Ulcers (discovered on endoscopy and strictures evident on a barium swallow (which needed dilatations were scored as treatment induced, if the biopsy was negative. Factors likely to influence their outcome were analyzed. Results: The groups were matched for all patient and disease characteristics except pretreatment hemoglobin and Karnofsky performance score (KPS, which were lower in Gp E. The incidence of ulcers was 7%, 8%, 6% and 21% ( P =0.08 while that of strictures was 14%, 9%, 21% and 41% ( P =0.00 for the groups E, E+I, E+C and E+I+C respectively. On univariate analysis, patients with better KPS ( P =0.03, treated with narrow applicators (6 mm vs. 10 mm, P =0.00, received CT ( P =0.00 or assigned to Gp E+I+C ( P =0.00 were more likely to develop strictures, with a trend for development of ulcers in Gp.

  19. Cancer immunotherapy with surgery

    Full Text Available With the recent advances in the immunological surveillance system, an understanding of the role of host immunity has become essential to the management of carcinogenesis, tumor proliferation, recurrence and metastasis. Although it is important to continue chemical and surgical treatment of cancer, support of the anti-tumor immune system of the host should also be considered. Long term remission has been reported in leukemia by treating with BCG after chemotherapy whereas surgical treatment is usually more effective in preventing cancer recurrence in digestive organ cancer. The first step is extirpating the tumor as thoroughly as possible and the second step is chemo-immunotherapy. Cancer immunity, however weak, constitutes the basis for other treatments in selectively attacking cancer cells remaining after surgery, chemotherapy or irradiation. Immunotherapy should thus not replace chemotherapy or radiotherapy, but these methods should be employed in combination to attain more favorable results.

    The main methods to treat locally advanced non-small cell lung cancer are radiotherapy and chemotherapy. The combination of radiotherapy and chemotherapy includes sequential chemoradiotherapy and concurrent chemoradiotherapy. The effectiveness of concurrent chemoradiotherapy is superior to that of sequential chemoradiotherapy, but the toxicity of concurrent chemoradiotherapy increases as well. Continuing to explore new ways which can improve the effectiveness and reduce the toxicity is the current and future direction.

    Askin tumor is a tumor of the thoracopulmonary region that most commonly affects children and adolescents. These rare tumors are a form of primitive neuroectodermal tumor and typically carry a poor prognosis. Treatment is multimodal and consists of a combination of neoadjuvant chemotherapy, radical resection, and adjuvant chemo- and radiotherapy or all of the above. Surgery is advocated in most cases. We report a case of Askin tumor in a 54-year-old male who showed rapid and complete response to neoadjuvant chemotherapy. This allowed potentially radical surgery to be avoided. At one-year follow-up he remains disease-free.

    To evaluate the patterns of tumor shape and to compare tumor volume derived from simple diameter-based ellipsoid measurement with that derived from tracing the entire tumor contour using region of interest (ROI)-based 3D volumetry with respect to the prediction outcome in cervical cancer patients treated with concurrent chemotherapy and radiotherapy. Magnetic resonance imaging was performed in 98 patients with cervical cancer (stage IB-IIIB). The tumor shape was classified into two categories: ellipsoid and non-ellipsoid shape. ROI-based volumetry was derived from each magnetic resonance slice on the work station. For the diameter-based surrogate 'ellipsoid volume,' the three orthogonal diameters were measured to calculate volume as an ellipsoid. The more than half of tumor (55.1%) had a non-ellipsoid configuration. The predictions for outcome were consistent between two volume groups, with overall survival of 93.6% and 87.7% for small tumor (<20 mL), 62.9% and 69.1% for intermediate-size tumor (20-39 mL), and 14.5% and 16.7% for large tumors ({>=}40 mL) using ROI and diameter based measurement, respectively. Disease-free survival was 93.8% and 90.6% for small tumor, 54.3% and 62.7% for intermediate-size tumor, and 13.7% and 10.3% for large tumor using ROI and diameter based method, respectively. Differences in outcome between size groups were statistically significant, and the differences in outcome predicted by the tumor volume by two different methods. Our data suggested that large numbers of cervical cancers are not ellipsoid. However, simple diameter-based tumor volume measurement appears to be useful in comparison with ROI-based volumetry for predicting outcome in cervical cancer patients.

    Purpose: Data comparing the clinical outcomes of local brain radiotherapy (LBRT) and whole brain RT (WBRT) in patients with a single brain metastasis after tumor removal are limited. Patients and Methods: A retrospective analysis was performed to compare the patterns of treatment failure, cause of death, progression-free survival, median survival time, and Karnofsky performance status for long-term survivors among patients who underwent surgery followed by either LBRT or WBRT between 1990 and 2008 at the National Cancer Center Hospital. Results: A total of 130 consecutive patients were identified. The median progression-free survival period among the patients who received postoperative LBRT (n = 64) and WBRT (n = 66) was 9.7 and 11.5 months, respectively (p = .75). The local recurrence rates (LBRT, 9.4% vs. WBRT, 12.1%) and intracranial new metastasis rate (LBRT, 42.2% vs. WBRT, 33.3%) were similar in each arm. The incidence of leptomeningeal metastasis was also equivalent (LBRT, 9.4% vs. WBRT, 10.6%). The median survival time for the LBRT and WBRT patients was 13.9 and 16.7 months, respectively (p = .88). A neurologic cause of death was noted in 35.6% of the patients in the LBRT group and 36.7% of the WBRT group (p = .99). The Karnofsky performance status at 2 years was comparable between the two groups. Conclusions: The clinical outcomes of LBRT and WBRT were similar. A prospective evaluation is warranted.

    We evaluated the effectiveness and safety of ipsilateral radiotherapy for the patient with well lateralized tonsil cancer: not cross midline and <1 cm of tumor invasion into the soft palate or base of tongue. From 2003 to 2011, twenty patients with well lateralized tonsil cancer underwent ipsilateral radiotherapy. Nineteen patients had T1-T2 tumors, and one patient had T3 tumor; twelve patients had N0-N2a disease and eight patients had N2b disease. Primary surgery followed by radiotherapy was performed in fourteen patients: four of these patients received chemotherapy. Four patients underwent induction chemotherapy followed by concurrent chemoradiotherapy (CCRT). The remaining two patients received induction chemotherapy followed by radiotherapy and definitive CCRT, respectively. No patient underwent radiotherapy alone. We analyzed the pattern of failure and complications. The median follow-up time was 64 months (range, 11 to 106 months) for surviving patients. One patient had local failure at tumor bed. There was no regional failure in contralateral neck, even in N2b disease. At five-year, local progression-free survival, distant metastasis-free survival, and progression-free survival rates were 95%, 100%, and 95%, respectively. One patient with treatment failure died, and the five-year overall survival rate was 95%. Radiation Therapy Oncology Group grade 2 xerostomia was found in one patient at least 6 months after the completion of radiotherapy. Ipsilateral radiotherapy is a reasonable treatment option for well lateralized tonsil cancer. Low rate of chronic xerostomia can be expected by sparing contralateral major salivary glands.

    2015-05-01

    Radical trachelectomy is now recognized as a valid treatment option for young women with early-stage cervical cancer with lesions measuring less than 2 cm. However, for women with bulky lesions measuring greater than 2 cm, few data are available in the literature to guide management. There are currently 2 options available: either upfront radical trachelectomy or neoadjuvant chemotherapy followed by fertility-preserving surgery. Overall, both options offer very good oncologic outcome; however, the rate of fertility preservation and obstetrical outcome seem superior after neoadjuvant chemotherapy. Advantages and disadvantages of both options are discussed and a thorough literature review is provided. Issues to be further studied are also outlined.

    Results: Oral cavity SCC has high chances of local failure when removed inadequately during surgery. Perineural spread, lymphovascular involvement and perinodal spread are important prognostic factors. Conclusions: Most patients of oral cavity cancer present in advanced stages. Close margins and perineural involvement are responsible for local recurrences while perinodal spread and lymphovascular involvement contributes to nodal recurrences. Tobacco consumption is important responsible factor. [Int J Res Med Sci 2016; 4(4.000: 1000-1004

    Full Text Available BACKGROUND: The effect of neoadjuvant chemotherapy (NAC on Gastric carcinoma (GC has been extensively studied, while its survival and surgical benefits remain controversial. This study aims to perform a meta-analysis of high-quality randomized controlled trials (RCTs, comparing efficacy, safety and other outcomes of NAC followed by surgery with surgery alone (SA for GC. METHODS: We systematically searched databases of MEDLINE, EMBASE, The Cochrane Library and Springer for RCTs comparing NAC with SA when treating GC. Reference lists of relevant articles and reviews, conference proceedings and ongoing trial databases were also searched. Primary outcomes were 3-year and 5-year survival rates, survival time, and total and perioperative mortalities. Secondary outcomes included down-staging effects, R0 resection rate, and postoperative complications. Meta-analysis was conducted where possible comparing items using relative risks (RRs and weighted mean differences (WMDs according to type of data. NAC-related objective response, safety and toxicity were also specifically analyzed. RESULTS: A total of 9 RCTs comparing NAC (n = 511 with SA (n = 545 published from 1995 to 2010 were identified. SA tended to be accompanied with higher overall mortality rate than NAC (46.03% vs 40.61%, RR: 0.83, 95% CI: 0.65-1.06, P = 0.14. Significantly, higher incidence of cases without regional lymph node metastasis observed upon resection were achieved among patients receiving NAC than those undergoing SA (25.68% vs 16.95%, RR: 1.92, 95% CI: 1.20-3.06, P = 0.006. All other parameters were comparable. Of the evaluable patients, 43.0% demonstrated either complete or partial response. The comprehensive NAC-related side-effect rate was 18.2% among patients available for safety assessment. CONCLUSIONS: NAC contributes to lowering nodal stages, and potentially reduces overall mortality. Response rate may be an important influential factor impacting advantages

  8. Omentum: An unusual site for distant metastasis for post-surgery radiotherapy treated squamous cell carcinoma larynx

    Full Text Available Squamous cell carcinoma of the larynx is the most common histologic type, accounting for up to 90% of cancers with more predilections to spread locoregionally to the cervical lymph nodes. Distant metastasis, usually to lungs, bone, and liver is seen much less frequently, with an overall incidence of 6.5–7.3%. A case of 55-year-old male with the previous history of surgery and radiotherapy treated squamous cell carcinoma of the larynx, presenting with a chief complaint of pain abdomen is hereby reported for its unusual diagnosis of metastatic deposits of squamous cell carcinoma in the omentum. Though there are reference available for peritoneum as the distant metastatic site for hypopharyngeal carcinoma, reference for laryngeal carcinoma metastasizing to omentum were not found even with an extensive search of literature. Awareness of unusual sites of distant metastasis such as omentum must be kept in mind for treated laryngeal carcinoma patients presenting with non-specific symptoms like pain abdomen. And also, chances of involvement of unusual site of the distant metastasis increases with advanced tumor-node-metastasis stage and nodal status.

    The prognosis of stage III non-small cell lung cancer (NSCLC) can be improved by a combination of radiotherapy (RT) and chemotherapy (CT). In this study, the GOTHA group evaluated the feasibility, tolerance, tumour response, pattern of failure and effect on survival of a combination alternating accelerated hyperfractionated (AH) RT and CT in patients with tumour stage III NSCLC. Toxic effects were leucopenia, nausea and vomiting, mucositis, diarrhoea, alopecia and peripheral neuropathy. Alternating CT and AHRT, as used in this study, were well tolerated and allowed full dose delivery within less than 12 weeks. Initial response was not predictive of survival. The survival curve is encouraging and the 5 year survival is superior to the 5% generally observed with conventionally fractionated radiotherapy. (author).

    Since the extract from berries of Aronia melanocarpa presents antioxidative properties in plasma and in blood platelets, not only from healthy group, but also from patients with benign breast diseases and in patients with invasive breast cancer before surgery, the aim of our present study was to evaluate the oxidative stress by measuring the level of various biomarkers of this process such as the generation of superoxide anion radicals (O(2)(-·)), the amount of carbonyl groups and 3-nitrotyrosine in proteins or the amount of glutathione in blood platelets isolated from breast cancer patients after the surgery and after various phases of the chemotherapy in the presence of A. melanocarpa extract (Aronox) in vitro. We demonstrated in platelet proteins from patients with invasive breast cancer (after the surgery and after various phases of the chemotherapy) higher level of carbonyl groups than in control healthy group. The level of 3-nitrotyrosine in platelet proteins from patients with invasive breast cancer was also significantly higher than in healthy subject group. We observed an increase of other biomarkers of oxidative stress such as O(2)(-·) and a decrease of GSH in platelets from patients with breast cancer (after the surgery and after various phases of the chemotherapy) compared to the healthy group. In model system in vitro our results showed that the commercial extract from berries of A. melanocarpa due to antioxidant action, significantly reduced the oxidative/nitrative stress in platelets from patients with invasive breast cancer caused by the surgery and various phases of the chemotherapy.

    During the last two decades, radiotherapy has become an integral part of the multidisciplinary approach in the treatment of patients with colorectal cancer. Currently, radiotherapy is seen mainly as an adjuvant therapy, sometimes in combination with chemotherapy, in a pre- or post-operative setting. Adjuvant radiotherapy alone leads to a significant reduction of local recurrence rates, but an impact on survival is seen only in subset analyses. Combined modality treatment can reduce local recurrence rates even further, and can also reduce the rate of distant relapses and increase survival. The acute toxicity of combined modality is considerably higher. Local radiation can also be used as a component of organ conserving local treatment for selected early lesions. Radiotherapy has been an important palliative treatment modality, diminishing symptoms in cases of inoperable primary rectal cancers or pelvic recurrences. The timing of radiation, surgery and chemotherapy has been under evaluation for years. For patients with locally advanced primary or recurrent malignancies (unresectable due to fixation), the preferred sequence is pre-operative irradiation with or without chemotherapy, followed by surgical resection. For mobile resectable lesions, sequencing issues are being tested in phase III randomised trials. (author).

    We reviewed treatment outcomes and prognostic factors for patients with salivary ductal carcinoma (SDC) treated with surgery and postoperative radiotherapy from 2005 to 2012. A total of 16 patients were identified and 15 eligible patients were included in analysis. Median age was 61 years (range, 40 to 71 years) and 12 patients (80%) were men. Twelve patients (80%) had a tumor in the parotid gland, 9 (60%) had T3 or T4 disease, and 9 (60%) had positive nodal disease. All patients underwent surgery and postoperative radiotherapy. Postoperative radiotherapy was delivered using 3-dimensional conformal radiotherapy or intensity-modulated radiotherapy. Locoregional failure-free survival (LRFFS), distant failure-free survival (DFFS), progression-free survival (PFS), and overall survival (OS) were calculated using the Kaplan-Meier method. Differences in survival based on risk factors were tested using a log-rank test. Median total radiotherapy dose was 60 Gy (range, 52.5 to 63.6 Gy). Four patients received concurrent weekly chemotherapy with cisplatin. Among 10 patients who underwent surgery with neck dissection, 7 received modified radical neck dissection. With a median follow-up time of 38 months (range, 24 to 105 months), 4-year rates were 86% for LRFFS, 51% for DFFS, 46% for PFS, and 93% for OS. Local failure was observed in 2 patients (13%), and distant failure was observed in 7 (47%). The lung was the most common involved site of distant metastasis. Surgery and postoperative radiotherapy in SDC patients resulted in good local control, but high distant metastasis remained a major challenge.

    Approximately 13% of women diagnosed with endometrial cancer present with advanced stage disease (International Federation of Gynecology and Obstetrics (FIGO) stage III/IV). The standard treatment of advanced endometrial cancer consists of cytoreductive surgery followed by radiation therapy, or chemotherapy, or both. There is currently little agreement about which adjuvant treatment is the safest and most effective. To evaluate the effectiveness and safety of adjuvant chemotherapy compared with radiotherapy or chemoradiation, and to determine which chemotherapy agents are most effective in women presenting with advanced endometrial cancer (FIGO stage III/IV). We searched the Cochrane Gynaecological Cancer Collaborative Review Group's Trial Register, the Cochrane Central Register of Controlled Trials (CENTRAL) (Issue 10 2013), MEDLINE and EMBASE up to November 2013. Also we searched electronic clinical trial registries for ongoing trials. Randomised controlled trials (RCTs) of adjuvant chemotherapy compared with radiotherapy or chemoradiation in women with FIGO stage III and IV endometrial cancer. Two review authors selected trials, extracted data, and assessed trials for risk of bias. Where necessary, we contacted trial investigators for relevant, unpublished data. We pooled data using the random-effects model in Review Manager (RevMan) software. We included four multicentre RCTs involving 1269 women with primary FIGO stage III/IV endometrial cancer. We considered the trials to be at low to moderate risk of bias. All participants received primary cytoreductive surgery. Two trials, evaluating 620 women (83% stage III, 17% stage IV), compared adjuvant chemotherapy with adjuvant radiotherapy; one trial evaluating 552 women (88% stage III, 12% stage IV) compared two chemotherapy regimens (cisplatin/doxorubicin/paclitaxel (CDP) versus cisplatin/doxorubicin (CD) treatment) in women who had all undergone adjuvant radiotherapy; and one trial contributed no data

    Endometrial cancer is the fourth most prevalent cancer in Canadian women. Radiotherapy (RT) is frequently recommended as an adjuvant treatment. There is a high prevalence (>80%) of urinary incontinence (UI) after RT. It is plausible that UI is associated, at least in part, with alterations of the pelvic-floor muscles (PFM). The aim of this exploratory study was to compare the PFM functional properties of women reporting UI after hysterectomy and RT for endometrial cancer with those of women with a history of hysterectomy but without UI. A descriptive cross-sectional study was conducted. Eleven women were recruited for the affected group, and 18 were recruited for the comparison group. Urogenital and bowel functions were assessed using International Consultation on Incontinence Questionnaires, and PFM properties were evaluated using a Montreal dynamometer. Nonparametric tests were used for comparison of personal characteristics, functional status, and muscle properties. A correspondence analysis detailed the association between UI severity and PFM properties. Maximal opening of dynamometer branches, maximal vaginal length, PFM maximum force and rate of force development in a strength test, and number of rapid contractions during a speed test were reduced in the affected group. No significant difference was found for the endurance test. The severity of UI was found to correspond to the rate of force development and the number of rapid contractions in a speed test, endurance, age, and vaginal length. The results are limited to the population studied. The small sample size limited the strength of the conclusions. Some evidence of alterations in PFM properties were found in women with UI after hysterectomy and RT for endometrial cancer. These alterations appeared to be associated with UI, suggesting a possible role for rehabilitation.

    Full Text Available Abstract Background Long-term locoregional control in locally advanced squamous cell carcinoma of the head and neck (SCCHN remains challenging. While recent years have seen various approaches to improve outcome by intensification of treatment schedules through introduction of novel induction and combination chemotherapy regimen and altered fractionation regimen, patient tolerance to higher treatment intensities is limited by accompanying side-effects. Combined radioimmunotherapy with cetuximab as well as modern radiotherapy techniques such as intensity-modulated radiotherapy (IMRT and carbon ion therapy (C12 are able to limit toxicity while maintaining treatment effects. In order to achieve maximum efficacy with yet acceptable toxicity, this sequential phase II trial combines induction chemotherapy with docetaxel, cisplatin, and 5-FU (TPF followed by radioimmunotherapy with cetuximab as IMRT plus carbon ion boost. We expect this approach to result in increased cure rates with yet manageable accompanying toxicity. Methods/design The TPF-C-HIT trial is a prospective, mono-centric, open-label, non-randomized phase II trial evaluating efficacy and toxicity of the combined treatment with IMRT/carbon ion boost and weekly cetuximab in 50 patients with histologically proven locally advanced SCCHN following TPF induction chemotherapy. Patients receive 24 GyE carbon ions (8 fractions and 50 Gy IMRT (2.0 Gy/fraction in combination with weekly cetuximab throughout radiotherapy. Primary endpoint is locoregional control at 12 months, secondary endpoints are disease-free survival, progression-free survival, overall survival, acute and late radiation effects as well as any adverse events of the treatment as well as quality of life (QoL analyses. Discussion The primary objective of TPF-C-HIT is to evaluate efficacy and toxicity of cetuximab in combination with combined IMRT/carbon ion therapy following TPF induction in locally advanced SCCHN.

    Spinal intramedullary tuberculoma (SIT) is a rare manifestation of neurotuberculosis. Concurrent SIT and intracranial tuberculoma are further unusual. Most of these tuberculomas respond completely to medical therapy, and surgical excision is seldom required. In this report, we describe a 17-year-old boy who developed cervical intramedullary tuberculoma at C3-C6 level with a concurrent lesion involving the right cerebellar hemisphere while on treatment for tubercular meningitis. This patient had paradoxical increase in size of the cervical lesion even though the cerebellar lesion showed regression in size. In this article, we discuss the paradoxical response to anti-tubercular therapy in central nervous system tuberculosis, possible causes of nonresolution of tuberculoma on medical therapy and evaluate the role of surgery in these cases.

    Full Text Available Introduction: Intraoperative radiation therapy device (IORT is one of the several options for partial breast irradiation. IORT is sent to the tumor bed during surgery and can be replaced with conventional standard therapy (EBRT. The aim of this study was to evaluate the safety and effectiveness of IORT machine compared with EBRT and to determine the dominant option in terms of the cost-effectiveness. Method: This study was conducted in two phases; the first phase was a comprehensive review of the electronic databases search that was extracted after extraction and selection of the articles used in this article on effectiveness outcomes. Data collection form was completed by professionals and experts to estimate the cost of treatment, intraoperative radiotherapy and radiotherapy cost when using external radiation therapy process; direct costs were considered from the perspective of service provider and they were calculated in the second phase to determine the option of cost-effective ICER. Excel software was used for data analysis and sensitivity analysis was performed to determine the strength of the results of cost-effectiveness. Results:18 studies were selected but only 8 of them were shown to have acceptable quality. The consequences like “rate of cancer recurrence”, “seroma”, “necrosis”, “toxic”, “skin disorders and delayed wound healing” and “spread the pain” were among the consequences used in the selected articles. The total costs for each patient during a course of treatment for EBRT and IORT were estimated 1398 and $5337.5, respectively. During the analysis, cost-effectiveness of the consequences of cancer recurrence, seroma, necrosis and skin disorders and delayed wound healing ICER was calculated. And IORT was found to be the dominant supplier in all cases. Also, in terms of implications of toxicity and prevalence of pain, IORT had a lower cost and better effectiveness and consequently the result was more cost

    The low surgical cure rate in patients with stage III non-small cell lung cancer has prompted an exploration of multimodality treatment strategies. Mature results are presented from a phase II trial of accelerated hyperfractionated radiation therapy, concurrent paclitaxel/cisplatin chemotherapy and surgery for these patients. Between 1994 and 1997, 45 patients with surgically demonstrated stage III non-small cell lung cancer underwent induction treatment with a 96 h continuous cisplatin infusion (20 mg/m(2) per day) and a 24 h infusion of paclitaxel (175 mg/m(2)) given concurrently with accelerated hyperfractionated radiation therapy (1.5 Gy twice daily) to a total dose of 30 Gy. Induction was completed in ten treatment (12 total) days. Surgical resection was scheduled 4 weeks later with a second identical course of chemoradiotherapy given 4-6 weeks post-operatively, to a total radiation dose of 60-63 Gy. Thirty-five patients had stage III(A) disease and ten had stage III(B) disease (eight with N(3) tumors). Induction toxicity included nausea in 89%, dysphagia in 89%, and neutropenia tolerable despite significant myelosuppression. Locoregional control is excellent and survival is better than historical expectations. Patients downstaged to mediastinal node negativity have a prognosis similar to those with de novo stage I(B) and II disease. Distant metastases are the major cause of treatment failure.

    Full Text Available Abstract Background Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (HIPEC is a promising treatment for patients with peritoneal carcinomatosis (PC. Our objective was to identify new prognostic factors in patients with PC from colorectal cancer treated with this procedure. Methods All patients with PC from colorectal cancer treated by HIPEC from January 2000 to December 2007 were prospectively included. The tumor extension was assessed by the Peritoneal Cancer Index (PCI and the residual disease was recorded using the completeness cytoreductive score (CCs. All clinical and treatment data were computed in univariate and multivariable analyses using survival as primary end point. Results We carried out 51 complete procedures in 49 consecutive patients. The mean PCI was 10. The allocation of CCs was: CC-0 = 37, CC-1 = 14. The five-year overall and progression-free survival rate were 40% and 20%, respectively. Several prognostic factors for survival were identified by univariate analysis: PCI P P P = 0.06, area 5 (P = 0.031, area 7 (P = 0.014, area 8 (P = 0.022, area 10 (P P = 0.02. Only the involvement of the distal jejunum (area 10 was significant in the multivariable analysis (P = 0.027. Conclusions We demonstrated that the involvement of area 10 (distal jejunum of the PCI score was an independent factor associated with poor prognosis.

    Cytoreductive surgery (CRS) plus hyperthermic intraperitoneal chemotherapy (HIPEC) has been considered as a promising treatment modality for gastric cancer with peritoneal carcinomatosis (PC). However, there have also been many debates regarding the efficacy and safety of this new approach. Results from experimental animal model study could help provide reliable information. This study was to investigate the safety and efficacy of CRS + HIPEC to treat gastric cancer with PC in a rabbit model. VX2 tumor cells were injected into the gastric submucosa of 42 male New Zealand rabbits using a laparotomic implantation technique, to construct rabbit model of gastric cancer with PC. The rabbits were randomized into control group (n = 14), CRS alone group (n = 14) and CRS + HIPEC group (n = 14). The control group was observed for natural course of disease progression. Treatments were started on day 9 after tumor cells inoculation, including maximal removal of tumor nodules in CRS alone group, and maximal CRS plus heperthermic intraperitoneal chemoperfusion with docetaxel (10 mg/rabbit) and carboplatin (40 mg/rabbit) at 42.0 ± 0.5°C for 30 min in CRS + HIPEC group. The primary endpoint was overall survival (OS). The secondary endpoints were body weight, biochemistry, major organ functions and serious adverse events (SAE). Rabbit model of gastric cancer with PC was successfully established in all animals. The clinicopathological features of the model were similar to human gastric PC. The median OS was 24.0 d (95% confidence interval 21.8 - 26.2 d ) in the control group, 25.0 d (95% CI 21.3 - 28.7 d ) in CRS group, and 40.0 d (95% CI 34.6 - 45.4 d ) in CRS + HIPEC group (P = 0.00, log rank test). Compared with CRS only or control group, CRS + HIPEC could extend the OS by at least 15 d (60%). At the baseline, on the day of surgery and on day 8 after surgery, the peripheral blood cells counts, liver and kidney functions, and biochemistry parameters were all comparable. SAE

    To assess the use of radiotherapy (RT) or concurrent chemoradiotherapy (CRT) following taxane-based induction chemotherapy (T-ICT) in locally advanced head and neck squamous cell carcinoma (LAHNSCC) and to evaluate the tolerability of CRT after T-ICT. From 01/2006 to 08/2012, 173 LAHNSCC patients treated as a curative intent by T-ICT, followed by definitive RT/CRT were included in this analysis. There was an 86% objective response (OR) after ICT among 154 evaluable patients. Forty-four patients received less than three cycles (25%) and 20 received only one cycle of T-ICT. The 3-year actuarial overall survival (OS) was 49% and there was no OS difference according to the type of ICT (regimen or number of cycle) or the addition of concurrent CT (cisplatin, carboplatin, or cetuximab) to RT. In multivariate analysis (MVA), clinically involved lymph node (cN+), age more than 60 years, the absence of OR after ICT, and performance status of at least 1 predicted for a decreased OS, with hazard ratios (HR) of 2.8, 2.2, 2.1, and 2, respectively. The 3-year actuarial locoregional control (LRC) and distant control (DC) rates were 52 and 73%, respectively. In MVA, the absence of OR after ICT (HR: 3.2), cN+ (HR: 3), and age more than 60 years (HR: 1.7) were prognostic for a lower LRC whereas cN+ (HR: 4.2) and carboplatin-based T-ICT (HR: 2.9) were prognostic for a lower DC. The number of cycles (≤ 2) received during ICT was borderline significant for DC in the MVA (P=0.08). Among patients receiving less than or equal to three cycles of ICT, higher outcomes were observed in patients who received cisplatin-based T-ICT (vs. carboplatin-based T-ICT) or subsequent CRT (vs. RT). T-ICT in our experience, followed by RT or CRT, raises several questions on the role and type of induction, and the efficacy of CRT over RT. The role of RT or CRT following induction, although feasible in these advanced patients, awaits answers from randomized trials.

    Purpose: Concurrent cisplatin-based chemoradiotherapy (CRT) is the standard treatment for locally advanced cervical cancer. RTOG 0417 was a Phase II study exploring the safety and efficacy of the addition of bevacizumab to standard CRT. Methods and Materials: Eligible patients with bulky tumors (Stage IB-IIIB) were treated with once-weekly cisplatin (40 mg/m{sup 2}) chemotherapy and standard pelvic radiotherapy and brachytherapy. Bevacizumab was administered at 10 mg/kg intravenously every 2 weeks for three cycles. Treatment-related serious adverse event (SAE) and other adverse event (AE) rates within the first 90 days from treatment start were determined. Treatment-related SAEs were defined as any Grade {>=}4 vaginal bleeding or thrombotic event or Grade {>=}3 arterial event, gastrointestinal (GI) bleeding, or bowel/bladder perforation, or any Grade 5 treatment-related death. Treatment-related AEs included all SAEs and Grade 3 or 4 GI toxicity persisting for >2 weeks despite medical intervention, Grade 4 neutropenia or leukopenia persisting for >7 days, febrile neutropenia, Grade 3 or 4 other hematologic toxicity, and Grade 3 or 4 GI, renal, cardiac, pulmonary, hepatic, or neurologic AEs. All AEs were scored using the National Cancer Institute Common Terminology Criteria (CTCAE) v 3.0 (MedDRA version 6.0). Results: A total of 60 patients from 28 institutions were enrolled between 2006 and 2009, and of these, 49 patients were evaluable. The median follow-up was 12.4 months (range, 4.6-31.4 months).The median age was 45 years (range, 22-80 years). Most patients had FIGO Stage IIB (63%) and were of Zubrod performance status of 0 (67%). 80% of cases were squamous. There were no treatment-related SAEs. There were 15 (31%) protocol-specified treatment-related AEs within 90 days of treatment start; the most common were hematologic (12/15; 80%). 18 (37%) occurred during treatment or follow-up at any time. 37 of the 49 patients (76%) had cisplatin and bevacizumab

    Tumour cell proliferation during conventionally fractionated radiotherapy (RT) can negatively influence the treatment outcome in patients with unresectable non-small-cell lung cancer (NSCLC). Accelerated and hyperfractionated RT may therefore have an advantage over conventional RT. Moreover, earlier studies have suggested improved survival with addition of cisplatin-based chemotherapy (CT). We present here the results of combined treatment with induction and concomitant CT and accelerated hyperfractionated RT in a retrospective series of patients with advanced NSCLS. Between August 1990 and August 1995, 90 consecutive patients, aged 42-77 years (median 63 years), with locally advanced unresectable or medically inoperable NSCLC and good performance status were referred for treatment: stage: I 23%, IIIa 37%, IIIb 40%. Patient histologies included: squamous cell carcinoma 52%, adenocarcinoma 34% and large cell carcinoma 13%. The treatment consisted of two courses of CT (cisplatin 100 mg/m{sup 2} day 1 and etoposide 100 mg/m{sup 2} day 1-3 i.v.), the second course given concomitantly with RT. The total RT dose was 61.2-64.6 Gy, with two daily fractions of 1.7 Gy. A one-week interval was introduced after 40.8 Gy to reduce acute toxicity, making the total treatment time 4.5 weeks. Concerning toxicity, 33 patients had febrile neutropenia, 10 patients suffered from grade III oesophagitis and 7 patients had grade III pneumonitis. There were two possible treatment-related deaths, one due to myocardial infarction and the other due to a pneumocystis carinii infection. The 1-, 2- and 3-year overall survival rates were 72%, 46% and 34%, respectively; median survival was 21.3 months. Fifty-nine patients had progressive disease: 21 failed locoregionally, 29 had distant metastases and 9 patients had a combination of these. Pretreatment weight loss was the only prognostic factor found, except for stage. However, the results for stage IIIb were no different from those for stage IIIa

    Dermato-fibrosarcoma protuberans is a low incidence skin neoplasia of difficult management due to its high recurrence rate. Usual treatment consists of a large resection, some times causing functional and aesthetics impairment, and despite these efforts, published data point to a recurrence rate of 11% to 53%. Recently, radiotherapy has been used modifying the unreal course of this tumor, decreasing drastically the recurrence rate when compared to surgery only. We reviewed these treatment modalities and related three cases of large recurrent tumors treated in our plastic surgery department with surgery and adjuvant radiotherapy, without recurrences after 2 years follow up.

    Objective: To investigate the survival, recurrence patterns and risk factors in patients with stage ⅢA-N2 NSCLC treated with curative surgery and adjuvant chemotherapy and to explore the significance of postoperative radiation therapy. Methods: The clinical data of 290 patients with pathologically diagnosed stage ⅢA-N2 NSCLC after curative resection and adjuvant chemotherapy from January 2010 to December 2014 at our department were retrospectively analyzed. The survival and recurrence patterns were observed, and the factors affecting locoregional recurrence were analyzed. Results: The median survival time was 31.5 months. The 1-, 3-and 5-year survival rates were 88.3%, 46.0% and 33.2%, respectively. The median locoregional control time was 38.5 months. The 1-, 3-and 5-year locoregional control rates were 78.6%, 55.2% and 41.0%, respectively. The median distant metastasis-free survival was 26.8 months. The 1-, 3-and 5-year distant metastasis-free survival rates were 76.4%, 45.5% and 39.5%, respectively. The median progression-free survival was 19.1 months. The 1-, 3-and 5-year progression-free survival rates were 64.1%, 32.5% and 23.8%, respectively. Univariate analysis showed that clinical N status, histological type, pathological T stage, operation mode, the number of positive N2 lymph nodes and the number of positive N2 lymph node stations had a significant influence on overall survival; clinical N status, histological type, the number of positive N2 lymph nodes and the number of positive N2 lymph node stations had a significant influence on locoregional control. Multivariate analysis demonstrated that the number of N2 positive lymph nodes (P= 0.017) was an independent factor for overall survival of stage ⅢA-N2 patients; the number of N2 positive lymph nodes (P=0.009) and histological type (P=0.005) were independent factors for locoregional recurrence. For left-sided lung cancer, the lymph node station failure sites were mostly in 2R, 4R, 5, 6 and 7, and

    Disease relapses occur in up to 40% of cases after radiotherapy (RT) for early-stage glottic laryngeal neoplasms, and the foremost remaining treatment option is salvage total laryngectomy (STL). Our objectives were to review the outcomes of patients treated with salvage surgery after RT for early-stage carcinoma of the glottic larynx and to assess prognostic factors. We retrospectively analyzed 43 patients who underwent surgery. Overall and disease-free survival rates among subgroups were calculated and compared, stratified by preoperative stage, vocal cord mobility and postoperative histopathologic data. Recurrences occurred 22.7 months after the end of RT. Surgery was STL in 33 cases (76.8%). The main prognostic factors associated with survival rates were initial vocal cord mobility, vocal cord mobility at the diagnosis of recurrence, and changes in mobility. Vocal cord mobility is an important clinical criterion in treatment decision making for early-stage glottis carcinoma and remains important during follow-up.

  12. Chemotherapy resistance mechanisms in advanced skin cancer

    Full Text Available Melanoma is a most dangerous and deadly type of skin cancer, and considered intrinsically resistant to both radiotherapy and chemotherapy. It has become a major public health concern as the incidence of melanoma has been rising steadily over recent decades with a 5-year survival remaining less than 5%. Detection of the disease in early stage may be curable, but late stage metastatic disease that has spread to other organs has an extremely poor prognosis with a median survival of less than 10 months. Since metastatic melanoma is unresponsive to therapy that is currently available, research is now focused on different treatment strategies such as combinations of surgery, chemotherapy and radiotherapy. The molecular basis of resistance to chemotherapy seen in melanoma is multifactorial; defective drug transport system, altered apoptotic pathway, deregulation of apoptosis and/or changes in enzymatic systems that mediate cellular metabolic machinery. Understanding of alterations in molecular processes involved in drug resistance may help in developing new therapeutic approaches to treatment of malignant melanoma.

    鼻咽癌放化疗患者口腔反应较重,影响进食,当营养低于机体需要量时,越来越多的患者选择肠外营养途径满足机体需要。回顾我科2012年1月~2013年7月共收治119例鼻咽癌放化疗同步的患者,其中32例通过肠外营养补充营养素,采取有效护理干预帮住患者顺利完成治疗。%Radiotherapy and chemotherapy can lead to severe reactions in the oral cavity of the patients suf ering from nasopharyngeal carcinoma, which keep them from feeding. As nutrition taken in fails to satisfy the body requirements, more and more patients with nasopharyngeal carcinoma tend to do parenteral nutrition injection so as to meet such body requirements. After reviewing 110 cases of patients with nasopharyngeal carcinoma who receive synchronous radiotherapy and chemotherapy in our department from January, 2012 to July, 2013, we find that there are 32 cases replenishing nutrition by way of parenteral nutrition injection in which the ef ective nursing intervention is adopted to help such patients successful y complete their treatment.

    Full Text Available Background and objective To study the role of postoperative chemotherapy and its prognostic effect in Masaoka-Koga stage III and IV thymic tumors. Methods Between 1994 and 2012, 1,700 patients with thymic tumors who underwent surgery without neoajuvant therapy were enrolled for the study. Among them, 665 patients in Masaoka-Koga stage III and IV were further analyzed to evaluate the clinical value of postoperative chemotherapy. The Kaplan-Meier method was used to obtain the survival curve of the patients divided into different subgroups, and the Cox regression analysis was used to make multivariate analysis on the factors affecting prognosis. A Propensity-Matched Study was used to evaluate the clinical value of chemotherapy. Results Two-hundred-twenty-one patients were treated with postoperative chemotherapy, while the rest 444 cases were not. The two groups showed significant differences (P<0.05 regarding the incidence of myasthenia gravis, World Health Organization (WHO histological subtypes, pathological staging, resection status and the use of postoperative radiotherapy. WHO type C tumors, incomplete resection, and postoperative radiotherapy were significantly related to increased recurrence and worse survival (P<0.05. Five-year and 10-year disease free survivals (DFS and recurrence rates in patients who underwent surgery followed by postoperative chemotherapy were 51% and 30%, 46% and 68%, comparing with 73% and 58%, 26% and 40% in patients who had no adjuvant chemotherapy after surgery (P=0.001, P=0.001, respectively. In propensity-matched study, 158 pairs of patients with or without postoperative chemotherapy (316 patients in total were selected and compared accordingly. Similar 5-year survival rates were detected between the two groups (P=0.332. Conclusion Pathologically higher grade histology, incomplete resection, and postoperative radiotherapy were found to be associated with worse outcomes in advanced stage thymic tumors. At present

    2005-01-01

    Full Text Available Background: Combination of radical surgery and radiotherapy is the standard management of head and neck malignancies. But due to considerable morbidity of surgery and associated cosmetic and functional deficiencies, often aggravated by adjuvant radiotherapy, many patients prefer only radiotherapy with its′ decreased chance of survival. Proper surgical facilities are also not accessible to most of our patients. Neo-adjuvant chemotherapy and loco-regional management by surgery and / or radiotherapy have emerged as a viable alternative. Aims: The purpose of this study is to find out the survival outcome as well as toxicity profile of Neo-adjuvant chemotherapy with cisplatin and short infusional (3 hours 5-FU followed by radiotherapy in advanced head and neck malignancies. Materials and Methods: From June 2002 to December 2003, seventy four patients with advanced head and neck malignancies were planned to be treated with Cisplatin (50 mg / sq. meter on Days 1 and 2 and 5 - FU (600 mg / sq. meter on Days 1, 2 and 3 by 3 hour infusion on Day care basis. On completion of four cycles of chemotherapy at 21 days interval, all patients were destined to receive 6000 cGy of radiotherapy to the loco - regional site. Results: At one year follow up on completion of therapy, 57% patients were alive and 31% patients were disease free. These 31% patients enjoyed a good quality of life in terms of cosmetic and functional deficits. Toxicities were moderate and easily manageable. Conclusion: The study indicated that neo-adjuvant chemotherapy with Cisplatin and short infusional 5 - FU may be delivered on day care basis and results are comparable with Cisplatin and 96 hours continuous infusional 5 - FU. Thus avoiding the continuous infusional 5 - FU, 7 to 10 days in-patient hospitalization during each cycle may be avoided which is a constrain in developing countries like us.

    Protracted preoperative radio-chemotherapy with a 5-FU-based scheme, or a short course of preoperative radiotherapy without chemotherapy, are the standard neo-adjuvant treatments for resectable stage II-III rectal cancer. Local failure rates are low and reproducible, between 6 and 15% when followed with a 'Total Meso-rectal Excision'. Nevertheless, the therapeutic strategy needs to be improved: distant metastatic recurrence rates remain stable around 30 to 35%, while both sphincter and sexual sequels are still significant. The aim of the present paper was to analyse the ongoing trials listed on the following search engines: the Institut National du Cancer in France, the National Cancer Institute and the National Institute of Health in the United States, and the major cooperative groups. Keywords for the search were: 'rectal cancer', 'preoperative radiotherapy', 'phase II-III', 'preoperative chemotherapy', 'adjuvant chemotherapy' and 'surgery'. Twenty-three trials were selected and classified in different groups, each of them addressing a question of strategy: (1) place of adjuvant chemotherapy; (2) optimization of preoperative radiotherapy; (3) evaluation of new radiosensitization protocols and/or neo-adjuvant chemotherapy; (4) optimization of techniques and timing of surgery; (5) place of radiotherapy for non resectable or metastatic tumors.

    Following a number of accidents at radiotherapy units, at Epinal and Toulouse hospitals in particular, and the problems encountered in the summer 2008, mainly caused by a shortage of radiation physicians and probably due to legislation that bears little relation to reality, a national radiotherapy monitoring committee was set up on 15 December 2008 in the presence of Roselyne Bachelot-Narquin, France's Minister for Health and Sport. A first progress report was submitted to the Minister in May 2009. Twelve members sit on this national monitoring committee, including a CISS representative and a person that has received radiotherapy treatment. This demonstrates the seriousness and the commitment required of users on this issue. Radiotherapy, one of the main treatments for cancer, is a loco-regional treatment that uses radiation capable of destroying cancer cells. It can be used on its own, or before, during or after another treatment method (surgery or a medical treatment such as chemotherapy, for example). The decision to treat a patient by means of radiotherapy is based on the opinions of health care professionals discussed at a multidisciplinary team meeting, the minutes of which are sent to the various doctors involved. The radiotherapy treatment prescribed (the technique, total radiation dose, length of the treatment, number of sessions, etc.) is adapted to the individual situation of each patient. It is designed to be as effective as possible in light of the tumour pathology, while protecting neighbouring organs as far as is possible. (author)

    To examine the effect of suboptimal chemotherapy in patients undergoing preoperative chemoradiotherapy for the treatment of rectal cancer. The medical records of 43 patients who received preoperative concurrent chemoradiotherapy, followed by radical surgery for the treatment of pathologically proven adenocarcinoma of the rectum from April 2003 to April 2006 were retrospectively reviewed. The delivered radiation dose ranged from 41.4 to 50.4 Gy. The standard group consisted of patients receiving two cycles of a 5-FU bolus injection for three days on the first and fifth week of radiotherapy or twice daily with capecitabine. The standard group included six patients for each regimen. The non-standard group consisted of patients receiving one cycle of 5-FU bolus injection for three days on the first week of radiotherapy. The non-standard group included 31 patients. Radical surgery was performed at a median of 58 days after the end of radiotherapy. A low anterior resection was performed in 36 patients, whereas an abdominoperineal resection was performed in 7 patients. No significant difference was observed between the groups with respect to pathologic responses ranging from grades 3 to 5 (83.3% vs. 67.7%, p=0.456), downstaging (75.0% vs. 67.7%, p=0.727), and a radial resection margin greater than 2 mm (66.7% vs. 83.9%, p=0.237). The sphincter-saving surgery rate in low-lying rectal cancers was lower in the non-standard group (100% vs. 75%, p=0.068). There was no grade 3 or higher toxicity observed in all patients. Considering that the sphincter-saving surgery rate in low-lying rectal cancer was marginally lower for patients treated with non-standard, suboptimal chemotherapy, and that toxicity higher than grade 2 was not observed in the both groups, suboptimal chemotherapy should be avoided in this setting.

    Full Text Available Peritoneal carcinomatosis (PC is a difficult clinical challenge in colorectal cancer (CRC because conventional treatment modalities could not produce significant survival benefit, which highlights the acute need for new treatment strategies. Our previous case-control study demonstrated the potential survival advantage of cytoreductive surgery (CRS plus hyperthermic intraperitoneal chemotherapy (HIPEC over CRS alone. This phase II study was to further investigate the efficacy and adverse events of CRS+HIPEC for Chinese patients with CRC PC.A total of 60 consecutive CRC PC patients underwent 63 procedures consisting of CRS+HIPEC and postoperative chemotherapy, all by a designated team focusing on this combined treatment modality. All the clinico-pathological information was systematically integrated into a prospective database. The primary end point was disease-specific overall survival (OS, and the secondary end points were perioperative safety profiles.By the most recent database update, the median follow-up was 29.9 (range 3.5-108.9 months. The peritoneal cancer index (PCI ≤20 was in 47.0% of patients, complete cytoreductive surgery (CC0-1 was performed in 53.0% of patients. The median OS was 16.0 (95% confidence interval [CI] 12.2-19.8 months, and the 1-, 2-, 3-, and 5-year survival rates were 70.5%, 34.2%, 22.0% and 22.0%, respectively. Mortality and grades 3 to 5 morbidity rates in postoperative 30 days were 0.0% and 30.2%, respectively. Univariate analysis identified 3 parameters with significant effects on OS: PCI ≤20, CC0-1 and adjuvant chemotherapy over 6 cycles. On multivariate analysis, however, only CC0-1 and adjuvant chemotherapy ≥6 cycles were found to be independent factors for OS benefit.CRS+HIPEC at a specialized treatment center could improve OS for selected CRC PC patients from China, with acceptable perioperative safety.

In this study we evaluated the adverse effects at least 3 years post an accelerated hypofractionated whole breast radiotherapy schedule. Methods From October 2004 to March 2006, 39 consecutive patients aged over 18 years with pTis, pT1-2, pN0-1 breast adenocarcinoma who underwent conservative surgery were treated with an adjuvant accelerated hypofractionated radiotherapy schedule consisting of 34 Gy in 10 daily fractions over 2 weeks to the whole breast, followed after 1 week by an electron boost dose of 8 Gy in a single fraction to the tumour bed. Skin and lung radiation toxicity was evaluated daily during therapy, once a week for one month after radiotherapy completion, every 3 months for the first year and from then on every six months. In particular lung toxicity was investigated in terms of CT density evaluation, pulmonary functional tests, and clinical and radiological scoring. Paired t-test, Chi-square test and non-parametric Wilcoxon test were performed. Results After a median follow-up of 43 months (range 36-52 months, all the patients are alive and disease-free. None of the patients showed any clinical signs of lung toxicity, no CT-lung toxicity was denoted by radiologist on CT lung images acquired about 1 year post-radiotherapy, no variation of pulmonary density evaluated in terms of normalised Hounsfield numbers was evident. Barely palpable increased density of the treated breast was noted in 9 out of 39 patients (in 2 patients this toxicity was limited to the boost area and teleangectasia (2 limited to the boost area was evident in 2 out of 39 patients. The compliance with the treatment was excellent (100%. Conclusion The radiotherapy schedule investigated in this study (i.e 34 Gy in 3.4 Gy/fr plus boost dose of 8 Gy in single fraction is a feasible and safe treatment and does not lead to adjunctive acute and late

    It is estimated that 37% of the U.S. population is obese. It is unknown how obesity influences the operative and survival outcomes of cytoreductive surgery (CRS)/hyperthermic intraperitoneal chemotherapy (HIPEC) procedures. A retrospective analysis of a prospective database of 1,000 procedures was performed. Type of malignancy, performance status, resection status, hospital and intensive care unit stay, comorbidities, morbidity, mortality, and survival were reviewed. A total of 246 patients with body mass index (BMI) of >30 kg/m(2) underwent 272 CRS/HIPEC procedures. Ninety-five (38.6%) were severely obese (BMI > 35 kg/m(2)). A total of 135 (49.6%) procedures were performed for appendiceal and 60 (22.1%) for colon cancer. Median follow-up was 52 months. Both major and minor morbidity were similar for obese and non-obese patients. The 30-day mortality rates for obese and non-obese patients were 1.5 and 2.5%, respectively. Median intensive care unit and hospital stay were 1 and 9 days, regardless of BMI. The 30-day readmission rate was similar between obese and non-obese patients (24.8 vs. 19.4%, p = 0.11). Median survival for low-grade appendiceal cancer (LGA) was 76 months for obese patients and 107 months for non-obese patients (p = 0.32). Survival was worse for severely obese patients (median survival 54 months) versus non-obese patients with LGA (p = 0.04). Survival was similar for obese and non-obese patients with peritoneal surface disease (PSD) from colon cancer or high-grade appendiceal cancer. Obesity does not influence postoperative morbidity or mortality of patients with PSD, regardless of primary tumor. Severe obesity is associated with decreased long-term survival only in patients with LGA primary disease; however, application of CRS/HIPEC still offers meaningful prolongation of life. Obesity should not be considered a contraindication for CRS/HIPEC procedures.

    Full Text Available SUMMARY. Collaboration of a multidisciplinary team of experts on the functional evaluation of patients with lung cancer was facilitated by the European Respiratory Society (ERS and the European Society of Thoracic Surgery (ESTS, in order to draw up recommendations and provide clinicians with clear, up-to-date guidelines on their fitness for surgery and chemo-radiotherapy. The subject was divided into various different topics, each of which was then assigned to at least two experts. The authors searched the literature according to their own strategies, with no central literature Review and compiled draft reports on each topic, which were then reviewed, discussed and voted on by the entire expert panel. The evidence supporting each recommendation was summarized, and graded as described by the Scottish Intercollegiate Guidelines Network Grading Review Group. Clinical practice guidelines were generated and finalized in a functional algorithm for risk stratification of the lung resection candidates, with emphasis on the cardiological evaluation, forced expiratory volume in 1 s (FEV1, systematic carbon monoxide lung diffusion capacity (DLCO and exercise testing. In contrast to lung resection, for which the scientific evidence is more robust, it was not possible to recommend any specific test, cut-off value, or algorithm for chemo-radiotherapy, due to the lack of data. It is highly recommended that patients with lung cancer should be managed in specialized units by experienced multidisciplinary teams. Pneumon 2010, 23(1:80-102.

    Objective: To assess the therapeutic effectiveness of preoperative neoadjuvant chemotherapy using a combination of paclitaxel and carboplatin on local advanced non-small cell lung cancer (NSCLC). Methods: Twenty-five patients with advanced NSCLC were treated with paclitaxel and carboplatin for 2 to 4 cycles before undergoing tumor resection and then postoperative chemotherapy/radiotherapy therapy for 2 to 4 cycles. Results: Following neoadjuvant chemotherapy, the most prominent side-effect was bone marrow restraint. The overall response rate of preoperative chemotherapy was 56%. The mean survival time was 26.5 months, with 1-, 2- and 5-year survival rates of 55%, 25%, and 16%, respectively. All NSCLC patients survived the perioperative period. Conclusion: Preoperative neoadjuvant chemotherapy combining paclitaxel and carboplatin produced minimal side-effect while increasing the probability that advanced NSCLC patients would be able to undergo surgery thus improving their prognosis.

    Objective: To compare the efficacy of induction chemotherapy (IC) plus intensity-modulated radiotherapy (IMRT) with that of concurrent chemo-radiotherapy (CCRT) plus adjuvant chemotherapy (AC) for patients with loco-regionally advanced naso-pharyngeal carcinoma (NPC). Methods:Data of 240 patients with loco-regionally advanced NPC were reviewed. These patients were admitted to the Sun Yat-sen University Cancer Center between January 2004 and December 2008. Among the 240 patients, 117 under-went the IC+IMRT and 123 were treated with the CCRT+AC. The IC+IMRT group received a regimen including cisplatin and 5-fluoro-uracil (5-FU). The CCRT+AC group received cisplatin concurrently with radiotherapy and subsequently received adjuvant cisplatin and 5-FU. The survival rates of the patients were assessed by Kaplan-Meier analysis, and the survival curves were compared by Log-rank test. Multivariate analysis was conducted using Cox proportional hazard regression model. Results:The 5-year overall survival (OS), disease-free survival, distant metastasis-free survival, local relapse-free survival, and the nodal relapse-free survival were 78.0%versus 78.7%, 68.9%versus 67.5%, 79.0%versus 77.0%, 91.6%versus 91.0%, and 95.3%versus 93.7%in the IC+IMRT and CCRT+AC groups, respectively. The survival between the two groups exhibited no significant differences. Higher rates of Grades 3 to 4 nau-sea-vomiting (8.1%vs. 1.7%, P=0.023) and leukopenia (9.7%vs. 0.9%, P=0.006) were observed in the CCRT+AC group. Multivariate analysis revealed that N stage and age were significant prognostic factors for the OS of the patients with loco-regionally advanced NPC. Conclusion:The treatment outcomes of IC+IMRT and CCRT+AC were similar. Distant metastasis remained as the predominant mode of treatment failure.%目的:比较诱导化疗加调强放疗和同期放化疗加辅助化疗治疗局部晚期鼻咽癌的疗效。方法:收集2004年1月至2008年12月中山大学肿瘤医院收治的经病
