Expression of Survivin and its relationship to prognosis in human hepatocellular carcinoma / 中国病理生理杂志

ABSTRACT

AIM: To study the expression of Survivin and its relationship to prognosis in human hepatocellular carcinoma(HCC).METHODS: The expression of Survivin protein in 83 cases of HCC and their neighboring noncancerous tissues was detected by immunohistochemistry. The expression of Survivin mRNA in 11 cases of HCC and their neighboring noncancerous tissues was detected by semi-quantitative RT-PCR. RESULTS: Survivin protein expression was detected in 53 of 83 (63.9%) HCC tissues and 21 of 53 (39.6%) corresponding noncancerous tissues. 22 of 53 Survivin-positive HCCs (41.5%) showed punctate nuclear staining in HCC cells, 24 of 53 Survivin-positive HCCs (45.3%) showed cytoplasmic staining in HCC cells and the remaining 7 showed both nuclear and cytoplasmic staining. The positive rates of nuclear Survivin expression in cases of envelope invasion or tumor metastasis were significantly higher than those in cases without envelope invasion or tumor metastasis (P
