ABSTRACT
Purpose To study the expression of TMPRSS2, ERG and ETV1 in prostatic cancer and their clinical pathologic signifi-cance. Methods Tissue microarray and immunohistochemistry (MaxVision) were used to detect TMPRSS2, ERG and ETV1 expres-sion in 70 prostatic cancer tissues, 10 prostatic intraepithelial neoplasia tissues and 18 benign prostate tissues. Results There was no statistical significance on positive rate of the expression of TMPRSS2 among prostatic cancer tissues, prostatic intraepithelial neoplasia tissues and benign prostate tissues (P>0. 05). The positive rate (81. 4%) of ERG in prostatic cancer tissues was significantly higher than that in prostatic intraepithelial neoplasia tissues ( 30. 0%) and benign prostate tissues ( 0. 0 ) ( P 0. 05). The expression of TMPRSS2, ERG and ETV1 was positively correlated to Gleason score and clinical stage (P0. 05). Conclusion ERG and ETV1 are expected to become therapeutic targets for prostate cancer. Detecting TMPRSS2, ERG and ETV1 at the same time is helpful to diagnosis and differential diagnosis of prostatic cancer, which might be new molecule markers of prostate cancer.
