[Indications and results of radical treatment of gallbladder carcinoma]

Extended cholecystectomy is the only chance of a cure for patients with locally advanced cancer of the gallbladder. The aim of the study was to evaluate the short- and long-term results of surgical treatment and to define the prognostic factors associated with better survival. We conducted a retrospective study in 81 patients with gallbladder cancer admitted to our surgical department from 1985 to 1999. Radical surgery was performed on 39 patients. The type of surgical treatment was based on the TNM stage of the disease: all but stage I patients underwent extended cholecystectomy (resection of segment IVa-V, N1-2 lymph-node dissection). The mortality and morbidity rates were 5.1% and 28.2%, respectively. In the patients undergoing curative resection, the 5-year survival was 31.5% (75% in T1 patients, 57.1% in T2, 25.9% in T3 and 0% in T4. Long-term survival of patients with T1-2 tumours was significantly better than that of T3 (P = 0.02) or T4 patients (P = 0.0003); 53.6% of N0 patients were still alive at 5 years as against only 14.5% of N+ patients (P = 0.06). Depth of infiltration is an important prognostic factor. The presence of lymph-node metastases should not be a contraindication to surgery since long-term survival is possible.
