Five-year survivors after aggressive surgery for stage IV gallbladder cancer.

ABSTRACT

PURPOSE: To describe 5-year survivors after radical surgery for stage IV gallbladder cancer and to determine the characteristics leading to potential long-term survival. METHODS: Of 59 patients undergoing radical resection for stage IV disease between 1979 and 1994, 6 patients who have survived for more than 5 years were followed up. RESULTS: Three patients had developed obstructive jaundice due to involvement of the hepatic hilum, but the other three had not. The jaundiced patients had remarkable tumor spread over the bile duct and right hepatic artery within the hepatoduodenal ligament. However, the proper and left hepatic arteries and the portal trunk and its left branch were free from tumor involvement. The nonjaundiced patients had N1 or N2 lymph node metastasis. However, none underwent bile duct resection or pancreatoduodenectomy to establish radical lymphadenectomy. CONCLUSIONS: Selected patients with stage IV gallbladder cancer may be candidates for 5-year survival when the primary tumor is fairly localized even if it forms a large mass and involves neighboring organs including the hepatic duct, lymph node metastasis is limited to N1 and N2 except for the celiac and superior mesenteric nodes and is less infiltrative, and distant metastasis including that in the paraaortic area is absent.
