  • Ovulation Induction and Risk of Ovarian Cancer: A Systematic Review

    Objective To systematically assess literature regarding the relationship between ovulation induction and the risk of ovarian cancer. Methods We searched MEDLINE, EMbase, The Cochrane Library, CBM and CNKI (from inception to Feb, 2012). Cohort or case-control studies were identified according to the inclusion and exclusion criteria. Then the quality of the included studies was assessed, and the data was extracted. Meta-analysis was performed by RevMan 5.0 software. The incorporated RR (relative risk) and 95%CI (confidence interval) of the included cohort studies and incorporated OR (odds ratio) and 95%CI of case-control studies were calculated, respectively. Results Four cohort studies and four case-control studies were included. Result of meta-analysis on cohort studies showed ovulation induction didn’t increase the risk of ovarian cancer (RR=1.07, 95%CI 0.81 to 1.42, P=0.63). Besides, result of meta-analysis on case-control studies showed ovulation induction was not associated with the incidence of ovarian cancer (OR=1.28, 95%CI 0.78 to 2.08, P=0.33). But the risk of borderline ovarian tumors increased when compared with general population controls (OR=1.71, 95%CI 1.05 to 2.79, P=0.03). Conclusion Ovulation induction does not increase the risk of ovarian cancer, but may relate to the incidence of borderline ovarian cancer. However, more high-quality studies, especially perspective cohort studies are required because of the limited quantity of the included studies.
