BACKGROUND/AIMS: To compare patients with gallbladder cancer treated with radical resection and regional lymphadenectomy (RR-RL) versus simple cholecystectomy and adjuvant external radiotherapy (SC-ERT) and determine outcome. METHODOLOGY: Presentation, operative data, complications and survival were examined in 137 patients. In particular, the 45 patients treated with RR-RL or SC-ERT. RESULTS: Twenty-five had SC-ERT and 20 had a RR-RL. There were no epidemiological differences between groups. Resection of segments IV-b and V and en bloc dissection of regional lymph nodes was the most frequently used procedure (75%). The morbidity and mortality of the radical procedure were 25% and 10%. The morbidity of SC-ERT was 16%. All patients with Nevin I are alive. For lesions Nevin II and Nevin III RR-RL offered a 100% 5-year survival rate and SC-ERT had a 62% and 39% 5-year survival rate respectively. For lesions Nevin IV and V there was no difference in long-term survival. CONCLUSIONS: RR-RL is better than SC-ERT in patients with Nevin II and III lesions because it improves survival rate. SC-ERT can be recommended as an alternative treatment. For more advanced lesions further trials are needed.
