Core Tip

Core Tip: Gallbladder mucinous adenocarcinoma (GBMAC) is a rare subtype of gallbladder adenocarcinoma (GBAC), with limited knowledge of its survival outcomes. Based on a large database, we compared the clinicopathological characteristics of GBMAC with typical GBAC and identified prognostic factors for GBMAC. The results showed that the biological behaviors of GBMAC are significantly different from typical GBAC, while survival outcomes for GBMAC patients were not worse than those for typical GBAC patients. Surgery, chemotherapy, and lower American Joint Committee on Cancer stage were associated with better survival outcomes.
