Background and Objectives: Current management guidelines recognize the impact of hepatic versus peritoneal sided gallbladder cancers (GBC) on survival. However, no data exist regarding the significance of anatomic tumor location within the gallbladder. Methods: We retrospectively analyzed all GBC that underwent surgical resection with curative intent in our health system from 2007 to 2017. We evaluated the effect of anatomic pathologic tumor location (fundus/body, neck, and multifocal) on clinicopathologic, perioperative, and oncologic outcomes. Results: About 97 patients met criteria; 63% fundus/body, 22% multifocal, and 15% neck. Compared with fundus/body, neck tumors more frequently presented with preoperative jaundice (53% vs. 13%, p <.001), were smaller (20 mm vs. 30 mm, p =.068) and had significantly more biliary tree invasion (33% vs. 13%, p =.030) on histopathology. Although tumor characteristics (pTNM stage, liver invasion, lymphovascular invasion, prognostic nutritional index, and grade) were similar, neck tumors had significantly higher rates of R0 resection (53% vs. 11%, p <.001). Rates of adjuvant therapy were similar. Median PFS was similar between cohorts (p =.356). However, median overall survival (OS) was significantly shorter in neck (21 months) than fundus/body tumors (NR > 109 months), p =.015. Conclusions: Neck tumors were rare, small and more likely to result in jaundice secondary to biliary tree invasion. Despite higher R0 resection rates, these tumors had significantly worse OS.
