Expression of proliferating cell nuclear antigen(PCNA) in ovarian serous cystadenocarcinoma and its relation to prognosis

Objective To investigate the expression of proliferating cell nuclear antigen (PCNA) in ovarian serous cystadenocarcinoma and its relation to the characteristics of biological behavior and prognosis. Methods PC10 immunostaining was used to stain PCNA in archival paraflin-embedded tissues. Results PCNA immunostaining was performed successfully in ovarian serous tumors, the expression of PCNA was significantly elevated in serous cystadenocarcinomas compared with serous cystadenoma and borderline serous cys...
