Abstract：Objective To investigate the expression of Golgi protein?73(GP73) and Ki?67 antigen in gallbladder carcinoma ,and to analyze their correlations with proliferation ,invasion ,and prognosis of gallbladder carcinoma. Methods Streptavid?in?peroxidase (SP) immunohistochemistry was used to detect the expression of GP73 and Ki?67 in surgically resected specimens of 58 gallbladder carcinomas ,15 gallbladder adenomas and 15 gallbladder polyps samples . Results The positive rates of GP73 and Ki?67 protein in gallbladder carcinomas were 72.4% and67.24%,respectively ,which wer significantly higher than those in gallbladder adenomas(GP73:40.0%,Ki?67:26.7%,P<0.05)and in gallbladder polyps(GP73:13.3%,Ki?67:25.0%,P<0.05).The expression of GP73 was positively correlated with tumor differentiation ,Nevin staging and lymph node metastasis(P < 0.05), and the expression of GP73 was positively correlated with tumor differentiation ,Nevin staging(P < 0.05). GP73 expression was positively correlated with Ki?67 expression in gallbladder carcinoma (r = 0.473 ,P = 0.000). Patients with negative expression of GP73 and Ki?67 had longer survival time than those with positive expression of GP73 and Ki?67. Conclusion The expression of GP73 and Ki?67 was associated with proliferation ,invasion of gallbladder carcinoma. The combined detection of GP73 and Ki?67 is conducive to judging the progress and prognosis of the gallbladder carcinoma .
