Abstract:
Objective To evaluate the clinical value of Nevin and AJCC staging system for gallbladder carcinoma. Methods In this study 90 patients diagnosed as gallbladder carcinoma underwent operation in Renji Hospital from February 2000 to October 2006. Patients were staged according to Nevin and AJCC staging system. The difference of survival rate, tumor resection rate, ratio of tumor-free resection margin and surgical procedures were analyzed. Results The survival rate, tumor resection rate and ratio of tumor-free resection margin decreased progressively with increasing Nevin and AJCC stage (P < 0. 05). There was no significant difference between the survival rate for Nevin Ⅲ or Ⅳ patients undergoing radical resection and simple cholecystectomy (P > 0. 05). In Nevin Ⅴ patients, the survival rate for radical and extensive radical resection patients was higher than for palliative patients (P < 0. 05). In AJCC Ⅲ patients, the survival rate for radical patients was significant higher than for palliative patients (P < 0. 05). Nosignificant difference was found between radical and palliative patients in survival time in AJCC Ⅳ (P > 0. 05). 52 patients in AJCC Ⅲ and Ⅳ were staged to Nevin Ⅴ according to Nevin staging system. The survival rate and resectable rate for the patients in AJCC Ⅲ were higher than in AJCC Ⅳ (P = 0. 0001, 0. 001 respectively). The rate of radical operation in AJCC Ⅲ was higher (P = 0. 001), and the rate of palliative operation in AJCC Ⅳ was higher (P = 0. 001). Conclusion Both Nevin and AJCC staging system are useful in the judgement of survival, reeectability, ratio of tumor-free resection margin and the optimal operation. AJCC staging system is more applicable for gallbladder carcinoma patients at advanced stage in terms of predicting prognosis.
