Purpose: To assess the value of direct colposcopic vision (DCV) for optimizing large loop excision of the transformation zone (LLETZ) for the treatment of cervical intraepithelial neoplasia (CIN). Methods: Data from 648 patients who underwent excisional procedures for CIN and were included in two previously published cohort studies were retrospectively reviewed. Women who had a LLETZ were included for analysis (n = 436). Margin status, surgical specimen dimensions and volume were analysed according to the use of colposcopy during procedure. Results: Compared to LLETZ guided by previous colposcopy report only, and to LLETZ performed immediately after colposcopy, DCV allowed for a significantly higher rate of clear margins: 33 (52.4 %), 104 (68.0 %) and 142 (84.5 %), respectively (p < 0.001). It also allowed for a significantly higher probability of achieving both negative margins and depth of specimen <10 mm: 10 (15.9 %) cases, 47 (30.7 %) cases and 125 (74.4 %) cases, respectively (p < 0.001). In multivariate analysis, when compared with the use of previous colposcopy report or with colposcopy immediately before the LLETZ, DCV allowed for a significantly higher probability of negative margins (AOR: 4.61; 95 % CI: 2.37-8.99 and AOR: 2.55; 95 % CI: 1.47-4.41), combined negative margins and depth <75th percentile (AOR: 3.67; 95 % CI: 1.97-6.86 and AOR: 3.05; 95 % CI: 1.91-4.87) and combined negative margins and volume <75th percentile (AOR: 12.96; 95 % CI: 5.99-28.05 and AOR: 6.16; 95 % CI: 3.75-10.14), respectively. Conclusions: When used with the LLETZ procedure, DCV allows for optimal outcomes in terms of negative resection margins, and minimized depth and volume of the excised specimen; and should therefore be recommended. © 2013 Springer-Verlag Berlin Heidelberg.

In 2010, in France, 8,790 men died from prostate cancer despite a low and decreasing mortality rate. The individual risk/benefit ratio of prostate cancer screening is the focus of controversy and currently not in favor of a systematic screening program. Therefore, only prevention could reduce incidence, side effects of treatment and related mortality. Interestingly, prostate cancer prevention is also a field of controversy mainly about 5-alpha-reductase inhibitors. However, it could be expected that pharmaco-or diet-based prevention will be a huge tool for cancer control, even more for prostate cancer burden. This review comprehensively analyses which molecules or compounds could be used in preventive trials. With regard to pharmaco-prevention, three different kinds of drugs could be identified. First drugs, which aim at mainly or even solely reduce prostate cancer risk such as 5-alpha-reductase inhibitors and selective estrogen receptor modulators. Drugs, which aim at wider preventive impact such as: nonsteroidal anti-inflammatory drugs or difluoromethylornithine. Lastly, drugs for which reducing prostate cancer incidence is merely a side effect such as statins, metformin or histones desacetylase inhibitors. With regard to diet-based prevention, two main approaches could be identified: aliments and nutriments, on one hand, and vitamin and minerals, on the other. Interestingly if compounds reach experimental plausibility, natural foods or even global diet seem to have a higher impact. Lastly, besides assessment of efficacy, effectiveness required the critical step of compliance, which might actually be the weakest link of the prevention chain. Source

The platelet refractoriness is a complication of transfusion treatments potentially dramatic in onco-haematology. Chemo-treatment of haematological malignancies or packs of allogeneic bone marrow transplants require iterative platelet transfusion requirements. The discovery of a platelet refractoriness along with its support should be the most reactive as possible but also adapted to the cause. In the case of allo-immunization, it may be expected. The purpose of this presentation is to recall the different etiologies and perform a feedback on the support transfusion platelet of onco-haematology adult patients at Institut Paoli-Calmettes (IPC) in partnership with the EFSAM. © 2014.

Breast cancer carrying BRCA mutation may be highly sensitive to DNA-damaging agents. We hypothesized a better outcome for BRCA-mutated (BRCAmut) metastatic breast cancer (MBC) patients receiving high-dose chemotherapy and autologous hematopoietic stem cell transplantation (HDC AHSCT) versus unaffected BRCA (BRCA wild type; (BRCAwt)) or patients without documented BRCA mutation (BRCA untested (BRCAut)). All female patients treated for MBC with AHSCT at Institut Paoli-Calmettes between 2003 and 2012 were included. BRCAmut and BRCAwt patients were identified from our institutional genetic database. Overall survival (OS) was the primary end point. A total of 235 patients were included. In all, 15 patients were BRCAmut, 62 BRCAwt and 149 BRCAut. In multivariate analyses, the BRCAmut status was an independent prognostic factor for OS (hazard ratio (HR): 3.08, 95% confidence interval (CI): 1.10–8.64, P=0.0326) and PFS (HR: 2.52, 95% CI :1.29–4.91, P=0.0069). In this large series of MBC receiving HDC AHSCT, we report a highly favorable survival outcome in the subset of patients with documented germline BRCA mutations.Bone Marrow Transplantation advance online publication, 4 April 2016; doi:10.1038/bmt.2016.82. © 2016 Macmillan Publishers Limited Source

Background:Prognosis of ovarian carcinoma is poor, heterogeneous, and not accurately predicted by histoclinical features. We analysed gene expression profiles of ovarian carcinomas to identify a multigene expression model associated with survival after platinum-based therapy.Methods:Data from 401 ovarian carcinoma samples were analysed. The learning set included 35 cases profiled using whole-genome DNA chips. The validation set included 366 cases from five independent public data sets.Results:Whole-genome unsupervised analysis could not distinguish poor from good prognosis samples. By supervised analysis, we built a seven-gene optimal prognostic model (OPM) out of 94 genes identified as associated with progression-free survival. Using the OPM, we could classify patients in two groups with different overall survival (OS) not only in the learning set, but also in the validation set. Five-year OS was 57 and 27% for the predicted Favourable and Unfavourable classes, respectively. In multivariate analysis, the OPM outperformed the individual current prognostic factors, both in the learning and the validation sets, and added independent prognostic information.Conclusion:We defined a seven-gene model associated with outcome in 401 ovarian carcinomas. Prospective studies are warranted to confirm its prognostic value, and explore its potential ability for better tailoring systemic therapies in advanced-stage tumours. © 2011 Cancer Research UK All rights reserved.
