A French Multicenter Real-Life Study on the Biological and Clinical Parameters Associated With Response to Immune Checkpoint Inhibitors (ICIs) in Second-Line Treatment of Advanced Urothelial Carcinoma: Impact of Antibiotics Administration at the Time of ICIs Initiation.

Background: After failure of first-line chemotherapy, standard of care for advanced urothelial cancer (aUC) is immune checkpoint inhibitors (ICIs) targeting PD-1/PD-L1 pathway. Several prognostic models (Bajorin and Bellmunt scores) have been evaluated, but only in the context of chemotherapy.

Objective: To study whether the variables in these scores and new emerging clinical and biological criteria have an impact on the probability of objective response in aUC treated with ICIs in 2nd-line setting and beyond.

Impact of age on tumor size in vulvar cancer: A multicenter study by the Francogyn group.

Objective: Vulvar cancer is a rare pathology affecting mainly elderly women. This study aims to evaluate the impact of age on tumor size in vulvar cancer.

Material And Methods: This was a multicenter retrospective observational study carried out between January 1, 1998, and December 31, 2020, in patients operated on for vulvar cancer.

Post-transplant cyclophosphamide versus anti-thymocyte globulin after reduced intensity peripheral blood allogeneic cell transplantation in recipients of matched sibling or 10/10 HLA matched unrelated donors: final analysis of a randomized, open-label, multicenter, phase 2 trial.

The use of post-transplantation cyclophosphamide (PTCy) for graft-versus-host disease (GVHD) prophylaxis is not established after reduced intensity conditioning (RIC) hematopoietic stem cell transplantation (HSCT) from fully matched donors. This was a randomized, open-label, multicenter, phase 2 trial. All patients received a RIC regimen with fludarabine, intravenous busulfan for 2 days (Flu-Bu2), and a peripheral blood stem cell (PBSC) graft from a matched related or 10/10 HLA-matched unrelated donor.

Rate of residual tumor after repeat surgery for positive margins in ductal carcinoma in Situ, and predictive factors.

Aims: To evaluate the rate of residual tumor in re-excision specimen of patients with positive margins in ductal carcinoma in situ (DCIS) following breast-conservative surgery, and to identify predictive factors of residual tumor.

Material And Methods: We conducted a monocentric, retrospective study, from January 2010 to December 2020. All 103 patients who underwent re-excision for positive margins in DCIS following breast-conservative surgery for in situ or invasive breast carcinoma were included.

Squamous Cell Carcinoma of the Lung With Microsatellite Instability in a Patient With Lynch Syndrome: A Case Report.

Lynch syndrome is the most common autosomal dominant inherited cancer predisposing syndrome, due to mutations in DNA mismatch repair genes. The key feature of cancers in Lynch syndrome is microsatellite instability and a high risk of developing mainly colorectal and uterine cancers. However, cancers with microsatellite instability outside this spectrum, for example, lung cancer, are extremely rare.

A thrombus is formed by a gradient of platelet activation and procoagulant endothelium.

Background: The contribution of platelets in thrombosis within microcirculation has been extensively documented in the literature. We previously showed, , that platelet activation revealed by intracellular calcium mobilization was a crucial step in the growth of thrombi following laser-induced injury, a model of thromboinflammation.

Objective: Our goal was to investigate the extent of platelet activation and the spatial distribution of platelets throughout a growing thrombus.

Regorafenib in patients with advanced Ewing sarcoma: results of a non-comparative, randomised, double-blind, placebo-controlled, multicentre Phase II study.

Background: The REGOBONE multi-cohort study explored the efficacy and safety of regorafenib for patients with advanced bone sarcomas; this report details the Ewing sarcoma (ES) cohort.

Methods: Patients with relapsed ES progressing despite prior standard therapy, were randomised (2:1) to receive regorafenib or placebo. Patients on placebo could crossover to receive regorafenib after centrally confirmed progression.

How to make a LLETZ simulator: LLETZ Simulator.

Large loop excision of the transformation zone (LLETZ) of the uterine cervix is a surgical procedure very frequently performed. Simulation of LLETZ under colposcopic guidance has a major role in training practitioners. The objective was to present an ex vivo model of LLETZ.

Brachytherapy and surgery versus surgery alone for IB2 (FIGO 2018) cervical cancers: A FRANCOGYN study.

Objective: Evaluation of the management by first brachytherapy followed by radical hysterectomy (Wertheim type) compared to radical hysterectomy alone (Wertheim type) for the treatment of IB2 cervical cancer.

Methods: Data from women with histologically proven FIGO stage IB2 cervical cancer treated between April 1996 and December 2016 were retrospectively abstracted from twelve French institutions with prospectively maintained databases.

Results: Of the 211 patients with FIGO stage IB2 cervical cancer without lymph node involvement included, 136 had surgical treatment only and 75 had pelvic lymph node staging and brachytherapy followed by surgery.

Regorafenib in patients with relapsed advanced or metastatic chordoma: results of a non-comparative, randomised, double-blind, placebo-controlled, multicentre phase II study.

Background: REGOBONE multicohort study explored the efficacy and safety of regorafenib for patients with advanced bone sarcomas; this report details the cohort of patients with relapsed advanced or metastatic chordoma.

Methods: Patients with relapsed chordoma progressing despite 0-2 prior lines of systemic therapy, were randomised (2 : 1) to receive regorafenib (160 mg/day, 21/28 days) or placebo. Patients on placebo could cross over to receive regorafenib after centrally-confirmed progression.

Predictors factors of the absence of high-grade intraepithelial lesion in excisional therapy specimen.

Objectives: To identify predictive factors of the absence of high-grade intraepithelial lesion (HGSIL) in cervical excisional therapy specimen.

Methods: Data from 835 women who underwent excisional therapy for a cervical intra epithelial lesion at the department of Gynaecology from two university hospitals, between January 2015 and December 2020 were reviewed. Demographic data, referral cytology, colposcopic findings, results of cervical biopsy and endocervical curettage were retrieved.

A Suggested Modification to FIGO Stage IV Epithelial Ovarian Cancer.

International Federation of Gynecology and Obstetrics (FIGO) staging classification for stage IV epithelial ovarian cancer (EOC) separates stages IVA (pleural effusion) and IVB (parenchymal and/or extra-abdominal lymph node metastases). We aimed to evaluate its prognostic impact and to compare survival according to the initial metastatic location. We conducted a multicenter study between 2000 and 2020, including patients with a FIGO stage IV EOC.

The role of tumor model in magnetic targeting of magnetosomes and ultramagnetic liposomes.

The combined passive and active targeting of tumoral tissue remains an active and relevant cancer research field. Here, we exploit the properties of two highly magnetic nanomaterials, magnetosomes and ultramagnetic liposomes, in order to magnetically target prostate adenocarcinoma tumors, implanted orthotopically or subcutaneously, to take into account the role of tumor vascularization in the targeting efficiency. Analysis of organ biodistribution in vivo revealed that, for all conditions, both nanomaterials accumulate mostly in the liver and spleen, with an overall low tumor retention.

Haploidentical Versus Matched Unrelated Donor Transplants Using Post-Transplantation Cyclophosphamide for Lymphomas.

When using post-transplantation cyclophosphamide (PTCy) graft-versus-host disease (GVHD) prophylaxis for lymphoma patients, it is currently unknown whether a matched unrelated donor (MUD) or a haploidentical related donor is preferable if both are available. In this study we wanted to test whether using a haploidentical donor has the same results of a MUD. A total of 2140 adults (34% Center for International Blood and Marrow Transplant Research, 66% European Society for Blood and Marrow Transplantation registry) aged ≥18 years who received their first haploidentical hematopoietic cell transplantation (haplo-HCT) or MUD-HCT (8/8 match at HLA-loci A, B, C, and DRB1) for lymphoma using PTCy-based GVHD prophylaxis from 2010 to 2019 were retrospectively analyzed.
