Proximal extrahepatic bile duct tumors. Analysis of a series of 52 consecutive patients treated over a period of 13 years.

Fifty-two consecutive patients with proximal extrahepatic bile duct tumors were treated by one of us (J.G.F.) between 1974 and 1987 at Memorial Sloan-Kettering Cancer Center, New York, NY. Thirty-eight patients (73%) underwent palliative procedures aimed at relieving the biliary obstruction (group A) and 14 patients (27%) were operated on with curative intent (group B). The choice of the surgical procedure employed to relieve the biliary obstruction did not significantly influence the length of survival of patients in group A in whom the median survival was 13.5 months and the in-hospital mortality was 15.7%. Fifty percent of the patients in group B underwent major liver resections to macroscopically encompass the tumor. In this group, although 35% of the patients experienced major complications, no in-hospital mortalities were encountered and the median actuarial survival was 38 months. The projected and crude 5-year survival rates were 28% and 21%, respectively. Age, gender, extent of resection, microscopic status of margins of resection, and grade of the lesion did not affect the length of survival in patients in group B. Locoregional failure, either isolated or as a component of peritoneal failure, was detected in the 6 patients in whom the disease has recurred. Eighty-three percent of the patients in whom the disease has recurred were dead within 12 months of the diagnosis of recurrence. Two long-term survivors (14%) developed second primary tumors in the follow-up period.
