RESUMO
Authors presented two different cases of ovarian cancer during pregnancy. The first case in the stage IA had favourable course. We performed ovariectomy in the second trimester. At the term of delivery cesarean section with total hysterectomy and omentectomy with following chemotherapy (PC) were carried out. The second case (IIIC stage) had a poor course and diagnosis (Cystadenocarcinoma papillary GIII). The management comprised of total hysterectomy and omentectomy with following chemotherapy (PAC + Bleomycin + Mitomycin). Despite our treatment the development of cancer was observed. The patient died after 8 months since operation. Early diagnosis and lower stage of cancer give better prognosis, however, clinical management is still discussed.
