Purpose To identify the prognostic role of adjuvant abdominal radiation therapy (RT) on oncologic outcomes as a part of multimodal treatment in the management of desmoplastic small round cell tumor (DSRCT) and to determine its impact according to the quality of surgical resection. Methods and Materials All patients treated for primary abdominal DSRCT in 8 French centers from 1991 to 2014 were included. Patients were retrospectively staged into 3 groups: group A treated with adjuvant RT after cytoreductive surgery, group B without RT after cytoreductive surgery, and group C by exclusive chemotherapy. Peritoneal progression-free survival (PPFS), progression-free survival (PFS), and overall survival (OS) were evaluated. We also performed a direct comparison between groups A and B to evaluate RT after cytoreductive surgery. Radiation therapy was also evaluated according to completeness of surgery: complete cytoreductive surgery (CCS) or incomplete cytoreductive surgery (ICS). Results Thirty-seven (35.9%), thirty-six (34.9%), and thirty (28.0%) patients were included in groups A, B, and C, respectively. Three-year OS was 61.2% (range, 41.0%-76.0%), 37.6% (22.0%-53.1%), and 17.3% (6.3%-32.8%) for groups A, B, and C, respectively. Overall survival, PPFS, and PFS differed significantly among the 3 groups (P<.001, P<.001, and P<.001, respectively). Overall survival and PPFS were higher in group A (RT group) compared with group B (no RT group) (P=.045 and P=.006, respectively). Three-year PPFS was 23.8% (10.3%-40.4%) for group A and 12.51% (4.0%-26.2%) for group B. After CCS, RT improved PPFS (P=.024), but differences in OS and PFS were not significant (P=.40 and P=.30, respectively). After ICS, RT improved OS (P=.044). A trend of PPFS and PFS increase was observed, but the difference was not statistically significant (P=.073 and P=.076). Conclusions Adjuvant RT as part of multimodal treatment seems to confer oncologic benefits for patients treated for abdominal DSRCT after cytoreductive surgery and perioperative chemotherapy. © 2016 Published by Elsevier Inc.

Aim: Sentinel lymph node (SLN) biopsy was recently recommended after prior breast tumour surgery and lymphadenectomy is not the gold standard anymore for nodal staging after a lesion's removal. The purpose of our study was to evaluate the good practices of use of SLN biopsy in this context. Patients and methods: From 2006 to 2012, 138 patients having undergone a surgical biopsy without prior diagnosis of an invasive carcinoma with a definitive histological analysis in favour of this diagnosis were included in a prospective observational multicentric study. Each patient had a nodal staging following SLN biopsy with subsequent systematic lymphadenectomy. Results: The detection rate of SLN was 85.5%. The average number of SLNs found was 1.9. The relative detection failure risk rate was multiplied by 4 in the event of an interval of less than 36 days between the SLN biopsy and the previous breast surgery, and by 9 in the event of using a single-tracer detection method. The false negative rate was 6.25%. The prevalence of metastatic axillary node involvement was 11.6%. In 69% of cases only the SLN was metastatic. The post-operative seroma rate was 19.5%. Conclusion: Previous conservative breast tumour surgery does not affect the accuracy of the SLN biopsy. A sufficient interval of greater than 36 days between the two operations could allow to improve the SLN detection rate, although further studies are needed to validate this statement.

Purpose: To analyze the feasibility, reproducibility, and impact on functional status of postoperative accelerated and partial breast irradiation (APBI) using interstitial high-dose rate-brachytherapy in women older than 70 years. Methods and Materials: From July 2004 to April 2008, 46 patients were screened for enrollment in a nationwide prospective Phase II trial. A total of 40 patients were eligible according to the inclusion criteria (aged >70 years, T1-2 <30mm, and pN0). The total delivered dose was 34Gy of 10 fractions for 5 days. Feasibility and reproducibility were evaluated using a Quality Index (QI) defined as (V100%-clinical target volume)/V100%. Skin toxicity was reported using Common Terminology Criteria for Adverse Events version 3.0. ABPI impact on functional dependence was evaluated using the Activity of Daily Living and Instrumental Activity of Daily Living scales. Reproducibility and feasibility were assessed with the optimal two-stage design of Simon. Results: Median age was 74 years (70-87 years). All patients were treated according to the protocol. Median Quality Index calculated for the 40 eligible patients was 13.3% (1-70%). It was considered acceptable, partially acceptable, and nonacceptable in 10, 28, and 2 patients, respectively. Within 12 months after APBI, overall rates of toxicity were 59%, 28%, and 2% for Grade 1, 2, and 3 events, respectively. Twelve months after APBI, 35 patients (87%) achieved excellent/good cosmetic result. Compared with baseline values, Activity of Daily Living and Instrumental Activity of Daily Living scores remained unchanged 6 and 12 months after APBI. Conclusions: APBI by means of high-dose rate-brachytherapy is a feasible/reproducible technique without significant impact on functional dependence in the treatment of elderly women with early breast cancer. © 2013 American Brachytherapy Society.

Background: Supportive care in cancer (SCC) was further enhanced in the Second National Cancer Act decreed in December 2009. The aim of our study was to assess current SCC efficacy. Patients and methods: The French speaking association for supportive care in cancer (AFSOS) conducted an observational study to evaluate practices, organisations and information given to patients. A specific 32 point questionnaire was sent to 1621 French physicians (MDs) caring for cancer patients. Results: Three different organisations were evaluated: the individual MDs, the transversal team and its particular structure specialised in global patient care specifically developed at comprehensive cancer centres-CCC. During their disease, 68% of patients received SCC, which was more available during the palliative period (90%) than at the diagnosis (44%). Our results found that 71% of cancer departments had a specific interdisciplinary cross-team to provide SCC, particularly in CCC (62%; p = 0.01) while 37% had specific inpatient units. A specific organisation dedicated to home care was greater in CCC than in public or private centres (69%, 45%, 20% respectively; p = 0.01). Adverse event information was performed more by an oncologist than other specialists (p = 0.01). Conclusion: Our results suggest that the specific SCC organisation could be a useful management tool to improve supportive care for cancer patients. © 2012 Elsevier Ltd. All rights reserved.

Purpose Social media and mobile technology are transforming the way in which young physicians are learning and practicing medicine. The true impact of such technologies has yet to be evaluated. Methods and Materials We performed a nationwide cross-sectional survey to better assess how young radiation oncologists used these technologies. An online survey was sent out between April 24, 2013, and June 1, 2013. All residents attending the 2013 radiation oncology French summer course were invited to complete the survey. Logistic regressions were performed to assess predictors of use of these tools in the hospital on various clinical endpoints. Results In all, 131 of 140 (93.6%) French young radiation oncologists answered the survey. Of these individuals, 93% owned a smartphone and 32.8% owned a tablet. The majority (78.6%) of the residents owning a smartphone used it to work in their department. A total of 33.5% had more than 5 medical applications installed. Only 60.3% of the residents verified the validity of the apps that they used. In all, 82.9% of the residents had a social network account. Conclusions Most of the residents in radiation oncology use their smartphone to work in their department for a wide variety of tasks. However, the residents do not consistently check the validity of the apps that they use. Residents also use social networks, with only a limited impact on their relationship with their patients. Overall, this study highlights the irruption and the risks of new technologies in the clinical practice and raises the question of a possible regulation of their use in the hospital. © 2014 Elsevier Inc.
