Abstract:
Objective To discuss the value of different staging systems for gallbladder cancer.Methods The clinical data of 132 patients with gallbladder cancer who had been admitted to Xinhua Hospital from October 1992 to December 2006 were retrospectively analyzed.The clinical stage and postoperative survival of patients in each stage were analyzed by Nevin staging system,staging systems of AJCC 5th and 6th edition.The survivals of patients were analyzed by Kaplan-Meier method and the comparison between groups was analyzed by Log-rank test.Results According to the Nevin staging system,the accumulative survivals of patients with stages Ⅰ,Ⅱ,Ⅲ,Ⅳ or Ⅴ were 80.3%,75.6%,43.2%,16.2% and 6.5%,respectively.The accumulative survivals of patients with stages Ⅰ,Ⅱ or Ⅲ were significantly higherthan those with stages Ⅳ or Ⅴ(χ~2=7.239,6.152,3.992,12.354,13.171,15.084,P＜0.05).According to the AJCC 5th edition staging system,the accumulative survivals of patients with stagesⅠ,Ⅱ,Ⅲ or Ⅳ were 71.4%,40.9%,10.2% and 5.8%,respectively.The accumulative survivals of patients with stages Ⅰ or Ⅱ were significantly higher than those with stages Ⅲ or Ⅳ (χ~2=18.286,23.729,5.541,13.607,P＜0.05),and the survivals of patients with stage Ⅲ were significantly higher than those with stage Ⅳ (χ~2=7.758,P＜0.05).According to the AJCC 6th edition staging system,the accumulative survivals of patients with stages Ⅰ,Ⅱ,Ⅲ or Ⅳ were 51.1%,11.7%,8.2% and 6.5%,respectively.Patients with stages Ⅰ or Ⅱ had a comparatively low survival,while the survivals of patients with stage Ⅰ were significantly higher than those with stages Ⅱ,Ⅲ or Ⅳ(χ~2=15.300,21.956,31.397,P＜0.05).Patients with stage Ⅱ had a higher survival than those with stage Ⅳ(χ~2=8.789,P＜0.05).There was no significant difference in survival between patients with stage Ⅱ and Ⅲ,and between patients with stage Ⅲ and Ⅳ.Conclusions The AJCC 5th edition staging system is still the perfect staging system of gallbladder cancer.The Nevin staging system is not integrating enough,while AJCC 6th edition staging system is too strict.
