Abstract:
Objective To investigate the efficacy of regional lymphadenectomy for patients with T2 gallbladder cancer. Methods From January 1990 to December 2009, 48 patients with T2 gallbladder cancer received regional lymphadenectomy following radical surgery at the Xinhua Hospital of Shanghai Jiaotong University, and their clinical data were retrospectively analyzed. Patients were divided into two groups according to the range of lymphadenectomy. Standard group (23 patients): lymph nodes in the regions of bile duct, common bile duct and hepatoduodenal ligament were dissected; extended group (25 patients): lymph nodes in the regions of hepatoduodenal ligament, head of pancreas, duodenum, portal vein, common hepatic artery and celiac axis were dissected).The condition of patients in the two groups were compared after the treatment. The morbidity and survival rate were analyzed by using Fisher exact test and Kaplan-Meier method, respectively, and the survival rates between the two groups were compared by using Log-rank test. Results No perioperative death was found in the two groups. The morbidities was 17% (4/23) in the standard group and 24% (6/25) in the extended group, with no significant difference between the two groups ( P ＞ 0.05 ). The 5-year cumulative survival rate and median survival time were 40% and 29.8 months in the standard group, and 66% and 53.2 months in the extended group, with significant differences between the two groups ( x2 = 4. 687, P ＜ 0.05 ). Conclusion Extended regional lymphadenectomy should be performed on patients with T2 gallbladder cancer if the primary lesions can be dissected radically.
