Gallbladder cancer (GBC) is a highly aggressive malignancy, which poses significant challenges for timely diagnosis, resulting in a dismal prognosis. Chemotherapy serves as a primary treatment option in cases where surgery is not feasible. However, the emergence of chemoresistance poses a significant challenge to the effectiveness of chemotherapy, ultimately resulting in a poor prognosis. Despite extensive research on mechanisms of chemotherapeutic resistance in oncology, the underlying mechanisms of chemoresistance in GBC remain poorly understood. In this review, we present the findings from the last decade on the molecular mechanisms of chemotherapeutic resistance in GBC. We hope that these insights may provide novel therapeutic and experimental targets for further investigations into this lethal disease.

CD19-CAR T-cell therapy induces deep tissue depletion of B cells.

Objectives: CD19-targeting chimeric antigen receptor (CAR) T-cell therapy can induce long-term drug-free remission in patients with autoimmune diseases (AIDs). The efficacy of CD19-CAR T-cell therapy is presumably based on deep tissue depletion of B cells; however, such effect has not been proven in humans in vivo.
Methods: Sequential ultrasound-guided inguinal lymph node biopsies were performed at baseline and after CD19-CAR T-cell therapy in patients with AIDs.
Background Incidental gallbladder carcinoma (IGBC) remains a significant clinical challenge, with its diagnosis often delayed due to the asymptomatic nature of the disease and its incidental discovery post-cholecystectomy. This study's aim is to calculate incidence in a high-risk, region-specific (North Indian) population and also to provide novel insights into clinical presentation as well as macroscopic and histopathological features of IGBC. Material and methods This retrospective observational study spanned four years (August 2013 to July 2016) and included a total of 3096 cases.

Biliary tract cancers (BTCs), including gallbladder and bile duct cancers, have a poor prognosis. Recent advances in chemotherapy, such as using targeted drugs for specific gene mutations, have improved outcomes. Gemcitabine plus cisplatin chemotherapy has been the standard of care for the primary treatment of BTCs, but secondary treatment had not been established until recently.

Cholangiocarcinoma (CCA) represents approximately 3% of all gastrointestinal cancers and is a highly heterogeneous and aggressive malignancy originating from the epithelial cells of the biliary tree. CCA is classified by anatomical location into intrahepatic (iCCA), extrahepatic (eCCA), gallbladder cancer (GBC), and ampullary cancers. Although considered a rare tumor, CCA incidence has risen globally, particularly due to the increased diagnosis of iCCA.
