Background: The north and north-eastern regions of India have among the highest incidence of gallbladder cancer (GBC) in the world. We report the clinicopathological charateristics and outcome of GBC patients in India.
Methods: Electronic medical records of patients diagnosed with GBC at Tata Medical Center, Kolkata between 2017 and 2019 were analyzed.
Results: There were 698 cases of confirmed GBC with a median age of 58 (IQR: 50-65) years and female:male ratio of 1.96. At presentation, 91% (496/544) had stage III/IV disease and 30% (189/640) had incidental GBC. The 2-year overall survival (OS) was 100% (95% CI: 100-100); 61% (95% CI: 45-83); 30% (95% CI: 21-43); and 9% (95% CI: 6-13) for stages I-IV, respectively (p = <0.0001). For all patients, the 2-year OS in patients who had a radical cholecystectomy followed by adjuvant therapy (N = 36) was 50% (95% CI: 39-64), compared to 29% (95% CI: 22-38) for those who had a simple cholecystectomy and/or chemotherapy (N = 265) and 9% (95% CI: 6-14) in patients who were palliated (N = 107) (p = <0.0001).
Conclusion: The combined surgical/chemotherapy approach for patients with stage II GBC showed the best outcomes. Early detection of GBC remains problematic with the majority of patients presenting with stage III-IV and who have a median survival of 9.1 months. Our data suggests that the tumor is chemoresponsive and multi-center collaborative clinical trials to identify alternative therapies are urgently required.

Emodin, as a natural active ingredient, has shown great application potential in the fields of medicine, food and cosmetics due to its unique pharmacological effects, such as anti-inflammatory, antioxidant, anti-cancer, etc. In recent years, with the development of science and technology and the increase of people's demand for natural medicine, emodin research has been paid more and more attention by the global scientific research community. The bibliometric analysis of emodin and the construction of knowledge map are still blank.

Purpose: To compare overall survival (OS), toxicity, and quality of life (QOL) in patients with metastatic gallbladder cancer receiving oral capecitabine (X) with best supportive care (BSC) and BSC alone.
Materials And Methods: Patients with metastatic gallbladder cancer and Karnofsky Performance Status (KPS) ≥70 were accrued and assigned to either arm A or B. Assignment to these two arms was based on physician/patient discretion.
Gallbladder-derived retinoic acid signalling drives reconstruction of the damaged intrahepatic biliary ducts.

Severe damage to the intrahepatic biliary duct (IHBD) network occurs in multiple human advanced cholangiopathies, such as primary sclerosing cholangitis, biliary atresia and end-stage primary biliary cholangitis. Whether and how a severely damaged IHBD network could reconstruct has remained unclear. Here we show that, although the gallbladder is not directly connected to the IHBD, there is a common hepatic duct (CHD) in between, and severe damage to the IHBD network induces migration of gallbladder smooth muscle cells (SMCs) to coat the CHD in mouse and zebrafish models.

Background: Special attention should be given to intra-abdominal adhesions in patients with a history of open cholecystectomy for gallstones or abdominal surgery. Choosing the appropriate surgical approach to remove the stones is crucial.
Patient Summary: A 68-year-old male was admitted due to sudden onset of upper abdominal pain lasting more than 6 h.
