Objective To investigate the'expression of Survivin in breast cancer tissue microarray, and its implication to clinic pathology and prognosis. Methods The expression of Survivin was studied in 80 cases of breast disease tissues ( 18 cases of hyperplasia of mammary glands and 62 cases of breast canc-er) and 20 cases of adjacent normal tissues by S-P immunohistochemisty to analysis the relationships be-tween its expression and history grade, clinic stage and lymphaden metastasis. Results The positive rates of Survivin were 0(0/20) in normal mammary glands, 33. 3% (6/18) in hyperplasia of mammary glands and 72. 5% (45/62) in breast cancer. There were significant difference between them (X~2= 34. 62, P <0. 01 ). The expression of Survivin was closely correlated to the stage and lymphaden metatasis and survival time ( P <0.05 or P <0.01), and it was negatively correlated to the histological grade ( P >0.05).Conclusions The expression of Survivin shows an ascending tendency in the carcinogenesis and progres-sion of breast cancer. The Survivin can promote the invasion and the metastasis of the cancer cell, and it is closely correlated to the prognosis.
