Real-world effectiveness and safety of CT-P13, an infliximab biosimilar, for inflammatory bowel diseases: A prospective national observational cohort study (ReFLECT study).

Background: ReFLECT was a French, prospective, multicenter, observational cohort study evaluating the effectiveness and safety of the infliximab (IFX) biosimilar CT-P13 in a real-world setting. Here, we describe the results for adults with inflammatory bowel disease (IBD).

Methods: Eligible patients with IBD were recruited and received intravenous CT-P13 induction and/or maintenance therapy; patients were either naive to IFX (IFX-naive) or previously treated with IFX originator or another IFX biosimilar (IFX-switched).

Comprehensive behavioural assessment of TERT in bladder cancer.

Background: Telomerase activity plays a crucial role in cancer development and progression. Thus, telomerase activation through the interplay of mutations and epigenetic alterations in the telomerase reverse transcriptase (TERT) promoter may provide further insight into bladder cancer induction and progression.

Methods: In this study 100 bladder tumour tissues were selected, and four molecular signatures were analysed: THOR methylation status, TERT promotor mutation, telomere length, and TERT expression.

Fast and efficient isolation of murine circulating tumor cells using screencell technology for pre-clinical analyzes.

Circulating tumor cells (CTCs) represent a rare and heterogeneous population of cancer cells that are detached from the tumor site and entered blood or lymphatic circulation. Once disseminated in distant tissues, CTCs could remain dormant or create a tumor mass causing serious danger for patients. Many technologies exist to isolate CTCs from patients' blood samples, mostly based on microfluidic systems or by sorting them according to their surface antigens, notably EpCAM, and/or cytokeratins for carcinoma.

Epstein-Barr virus and immune status imprint the immunogenomics of non-Hodgkin lymphomas occurring in immune-suppressed environments.

Non-Hodgkin lymphomas (NHL) commonly occur in immunodeficient patients, both those infected by human immunodeficiency virus (HIV) and those who have been transplanted, and are often driven by Epstein-Barr virus (EBV) with cerebral localization, raising the question of tumor immunogenicity, a critical issue for treatment responses. We investigated the immunogenomics of 68 lymphoproliferative disorders from 51 immunodeficient (34 post-transplant, 17 HIV+) and 17 immunocompetent patients. Overall, 72% were large B-cell lymphoma and 25% were primary central nervous system lymphoma, while 40% were EBV+.
