The purpose of this study is to further explore the roles of PDCD6 in epithelial ovarian cancer.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Methods<\/jats:title>\n            <jats:p>Lentiviral vector with shRNA for PDCD6 was used to investigate the effects of PDCD6 knockdown on cell growth, cell cycle, apoptosis and motility in ovarian cancer cells. Two hundred twelve epithelial ovarian cancer tissues were analyzed for mRNA expression of <jats:italic>PDCD6<\/jats:italic> using RT-PCR. Associations of its expression with clinical pathological factors, progression free and overall survival were evaluated.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Results<\/jats:title>\n            <jats:p>PDCD6 is highly expressed in metastatic ovarian cancer cells and positively regulates cell migration and invasion. Significantly, the level of <jats:italic>PDCD6<\/jats:italic> expression in epithelial ovarian cancer correlates with clinical progression. Patients with medium or high levels of <jats:italic>PDCD6<\/jats:italic> mRNA were at higher risk for disease progression, compared to those with low levels (HR, 1.29; <jats:italic>P<\/jats:italic> = 0.024 for medium levels; and HR, 1.57; <jats:italic>P<\/jats:italic> = 0.045 for high levels) after adjusting for age, disease stage, tumor grade, histologic type and residual tumor size. Kaplan-Meier survival analysis demonstrated similar results. However, no association was found between <jats:italic>PDCD6<\/jats:italic> expression and overall survival.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusions<\/jats:title>\n            <jats:p>PDCD6 seems to play an important role in ovarian cancer progression and it may be an independent predictor of progression free survival in epithelial ovarian cancer.
