Analysis of the Extent of Liver Oncological Extended Resection for Incidental Gallbladder Cancer: How Much Is Too Much?

Background: Liver resection is pivotal in treating incidental gallbladder cancer (IGBC). However, the adequate volume of liver resection remains controversial.

Methods: A cross-sectional retrospective analysis was performed on resected IGBC patients between 1999 and 2018.

Positive cystic duct margin at index cholecystectomy in incidental gallbladder cancer is an important negative prognosticator.

Background: Prognostic factors following index-cholecystectomy in patients with incidental gallbladder cancer (IGBC) are poorly understood. The aim of this study was to assess the value of the initial cystic duct margin status as a prognosticator factor and to aid in clinical decision making to move forward with curative intent oncologic extended resection (OER).

Methods: This retrospective study included patients with IGBC who underwent subsequent OER with curative intent at 2 centers (USA and Chile) between 1999 and 2016.

Incidental Gallbladder Cancer: Residual Cancer Discovered at Oncologic Extended Resection Determines Outcome: A Report from High- and Low-Incidence Countries.

Background: Gallbladder cancer detected incidentally after cholecystectomy (IGBC) currently is the most common diagnosis of gallbladder cancer, and oncologic extended resection (OER) is recommended for tumors classified higher than T1b. However, the precise prognostic significance of residual cancer (RC) found at the time of OER has not been well established. This analysis aimed to determine the prognostic impact of RC found in patients with IGBC undergoing OER.
