Stage I ovarian cancer cases during early, mid and late pregnancy periods: three case reports and review of the literature

Abstract

Since ovarian cancer during pregnancy is rare, the decisions regarding pregnancy discontinuation or fertility preservation are often difficult. We report three ovarian cancer cases detected at early, mid and late pregnancy periods in which both babies and mothers were saved. In particular, case 2 is the first reported instance of a sertoliform endometrioid carcinoma of the ovary during pregnancy. In addition, we review the clinical characteristics of previously reported patients with stage I ovarian cancer diagnosed during pregnancy. Even with stage Ia ovarian cancer, restaging laparotomy at cesarean section or post-delivery may be important to determine the treatment plan because staging during pregnancy is rarely complete.
