Recent guidelines on biliary cannulation are lacking. This guideline is an initiative of the World Endoscopy Organization (WEO) with the involvement of a panel of experts from Asia, Europe, and America. Relevant clinical questions on four areas (post‐endoscopic retrograde cholangiopancreatography [ERCP] pancreatitis [PEP] prophylaxis, biliary cannulation techniques, sphincterotomy/papillary balloon dilation, and biliary cannulation in special circumstances) were developed and answered after systematic reviews of the literature and using the Grading of Recommendations Assessment, Development, and Evaluation methodology. Successful biliary cannulation and sphincterotomy are cornerstones of ERCP and are indispensable for almost all therapeutic and advanced diagnostic procedures. However, adverse events, particularly PEP, may commonly occur and impair patients' outcomes. A high cannulation rate and a low rate of PEP are quality indicators for ERCP and should be the goal of all endoscopists. With this guideline we aimed to provide clinical practice advice applicable worldwide, regardless of resources and expertise availability. The main recommendations focus on specific aspects of ERCP, including pre‐, intra‐, and postprocedural measures to reduce the risk of PEP, the technique for an initial biliary cannulation attempt, options for cannulation in cases of difficult biliary access, alternatives to ERCP in case of failure (percutaneous‐ and endoscopic ultrasound‐guided), and biliary access in altered anatomy (periampullary diverticulum and postsurgical anatomy) and in the presence of duodenal stenosis.

ABSTRACTNodal follicular helper T‐cell (T FH) lymphoma of the angioimmunoblastic (AITL) subtype has a dismal prognosis. Using whole‐exome sequencing (n = 124), transcriptomic (n = 78), and methylation (n = 40) analysis, we identified recurrent mutations in known epigenetic drivers (TET2, DNMT3A, IDH2 R172 ) and novel ones (TET3, KMT2D). TET2, IDH2 R172 , DNMT3A co‐mutated AITLs had poor prognosis (p < 0.0001). Genes regulating T‐cell receptor (TCR) signaling (CD28, PLCG1, VAV1, FYN) or activation (RHOA G17V ) or regulators of the PI3K‐pathway (PIK(3)C members, PTEN, PHLPP1, PHLPP2) were mutated. CD28 mutation/fusion was associated with poor prognosis (p = 0.02). WES of purified, neoplastic T‐cell (CD3+PD1+) demonstrated high concordance with whole tumor biopsies and validated the presence of TET2 and DNMT3A in tumor and non‐lymphoid cells, but other mutations (CD28, RHOA G17V , IDH2 R172 , PLCG1) in neoplastic cells. Integrated DNA‐methylation and mRNA expression analysis revealed epigenetic alterations in genes regulating TCR, cytokines, PI3K‐signaling, and apoptosis. RNA‐seq analysis identified fusion transcripts regulating TCR‐activation (8%), revealed a restricted TCR‐repertoire (α = 87%, β = 72%), and showed the presence of Epstein–Barr virus transcriptome (73%). GEP demonstrated the association of B‐cells or dendritic cells in the tumor milieu with prognosis (p < 0.01). RNA‐seq and WES analysis of 12 AITL‐patient‐derived‐xenografts (PDX) showed that bi‐allelic TET2 and DNMT3A mutations or sub‐clonal mutations (PLCG1, PHLPP2) propagated in sequential passages, and gene signatures related to T FH and T CM (central‐memory) were well‐maintained through passages. Gene expression signatures associated with late PDX passages (3rd–5th) were enriched with proliferation and metabolic reprogramming‐related genes and predicted prognosis in an independent AITL series. Low PHLPP2 mRNA expression predicted poor prognosis (p = 0.05) and engineered PHLPP2 or TET2 loss in CD4+ T‐cells showed enhanced PI(3)K activation, thus uncovering a therapeutic target for clinical trials.

Black patients with metastatic prostate cancer have higher mortality rates compared to non-Hispanic White patients. There are no data on outcomes with [177Lu]Lu-PSMA-617 (LuPSMA) across racial groups. We evaluated the association between race and outcomes with LuPSMA in a multi-institutional cohort of consecutive patients with mCRPC treated with LuPSMA. The primary outcomes were PSA-50 rate, PSA-progression-free survival (PSA-PFS), and overall survival (OS). Statistical models were adjusted for age, number of prior therapies, sites of metastases, and baseline PSA. A total of 654 patients were included; 593 (91%) were White, 45 (7%) were Black and 16 (2%) were another non-Black minority (NBM). There were no statistically significant differences in PSA-50 rates, PSA-PFS and OS between the groups. Black and White patients treated with LuPSMA had similar clinical outcomes; efforts are needed to ensure Black and NBM patients have equal access to life prolonging therapies to narrow disparities in outcomes.

The NCCN Guidelines for Survivorship include screening, evaluation, and treatment recommendations for common physical and psychosocial problems resulting from adult-onset cancer and its treatment and provide a framework for coordination of survivorship care. They also include recommendations to help cancer survivors enhance their wellness and maintain a healthy lifestyle. These NCCN Guidelines Insights summarize the panel’s current recommendations and recent updates regarding physical activity, nutrition, and weight management for cancer survivors.
