Ovarian carcinoma during pregnancy: a study of 23 cases in Israel between the years 1960 and 1984.
Data from a study on malignant ovarian tumors in pregnancy in Israel are presented. During the 25-year period of the survey, 23 new cases of malignant ovarian tumors during pregnancy were diagnosed, representing an incidence of 0.12/100,000 females over the age of 14; over half of the patients were in their third decade of life at the time of diagnosis of the tumor. Ovarian malignant tumors during pregnancy are more prevalent in Jewish women of European-American origin than in those of Asian-African descent. Borderline carcinomas were found in 35% of our patients; epithelial invasive tumors were found in 30%; the other tumors were dysgerminoma (17%), granulosa cell tumor (13%), and undifferentiated carcinoma (5%). Most of the patients (74%) were diagnosed in stage I. In three cases, ovarian cancer was diagnosed during surgery for tubal pregnancy, and in two during cesarean section at term. In early-stage disease and low-potential-malignancy tumors, surgery can be conservative; thus, 14 of 23 bore a live child. In advanced disease, aggressive surgery, chemotherapy, and/or radiotherapy should be instituted. Factors affecting prognosis were age of patient, histologic type of tumor, and clinical stage of disease. Overall, the survival is much better than that for ovarian tumors in general, because most of the tumors are of low potential malignancy and are diagnosed at an early stage.
