Is radical surgery in locally advanced gallbladder carcinoma justified?

ABSTRACT

OBJECTIVES: Advanced gallbladder carcinoma is associated with a dismal long term prognosis. The aim of the present study was to evaluate the effectiveness of radical surgery in advanced stages of gallbladder carcinoma. METHODS: The course of 66 patients operated for advanced gallbladder carcinoma was evaluated in a retrospective study; 14% of patients had stage II, 29% had stage III, and 57% had stage IV tumors. Twelve patients underwent cholecystectomy (CHE) and lymphadenectomy of the hepatoduodenal ligament (LA); 17 patients underwent cholecystectomy combined with segment IV/V liver resection (CHE+LR) and LA; and 10 patients underwent right extended hemihepatectomy (EHH). Complete tumor resection (R0) was achieved in six patients with CHE and LA, in 14 patients with CHE combined with segment IV/V LR and LA, and in all patients with right EHH. Resections with microscopic residual tumor (R1) were performed in nine patients. Mean follow-up was 15.4 months (range 3-90 months). RESULTS: The perioperative mortality rate was 1.5%, and the morbidity rate was 20%. In R0 resections, mean survival was 23.3, 25.0, and 26.3 months for the patients who underwent CHE and LA, CHE combined with segment IV/V LR and LA, and right EHH, respectively. After 24 months, 46.4% of the patients with R0 resection were still alive compared with none of the patients with residual tumor. In the patients with R0 resection, no difference in survival was detected when node-negative status (pN0) was compared with positive locoregional lymph nodes (pN1a), whereas the degree of dedifferentiation (G2/G3) influenced survival. CONCLUSIONS: If complete resection is achieved, radical surgical procedures, including segment IV/V liver resection and extended right hepatectomy, significantly improve survival rates with an acceptable morbidity and mortality rate.
