RESUMEN
BACKGROUND: Biliary cancer includes cancer of the gallbladder as well as extrahepatic and intrahepatic cholangiocarcinoma. Surgery is the only curative treatment option available. Recently, much more aggressive surgical approaches have been employed. Therefore, we have investigated outcome of biliary cancer before and after establishment of an aggressive surgical approach. METHODS: Retrospective single-center analysis comparing two time periods of 5 years each. During the second period new surgical expertise and a much more aggressive surgical approach were used. RESULTS: In the first time period (5/1995-4/2000) only 29 patients with biliary cancer were treated at our institution, while a total of 85 patients were treated during the second time period (5/2000-4/2005). Surgical resection was attempted in 55% during the first period versus 62% in the second; resection was complete in 37.5% and 58.5%, respectively. Patients undergoing resection during the second time period were more likely to be without relapse compared with patients undergoing resection in the first time period. No patient from the first period is without evidence of disease, compared to 11 patients operated in the second period. Resected patients had better survival compared with unresected patients for all tumor locations (gallbladder, extrahepatic and intrahepatic cholangiocarcinomas). Overall survival of patients was not significantly different between patients treated during the first versus the second time period. CONCLUSION: In patients with biliary cancer surgical resection should be attempted whenever possible. However, long-term survival can be achieved only when a complete resection is obtained.
