Second primary genital malignancies associated with endometrial cancer.
Epidemiological data on Israeli patients with second primary genital malignancies associated with endometrial cancer is presented. During the 7 years of study, 29 (2.9%) of 1,007 patients with endometrial cancer had additional primary malignancy involving the genital organs. Of these, there were 25 (2.5%) ovarian and 4 (0.4%) cervical malignancies. The occurrence of a second malignancy was related to ethnic origin. The ratio of European/American to Asian/African Jewish descendants was 8.7 to 1. A significantly greater than expected incidence of ovarian and cervical malignancy was detected in the endometrial cancer patient (P less than 0.0001). The prognosis was mainly influenced by the clinical staging of disease at the time of diagnosis. Recognition of the fact that second primary cancers occur at a higher than expected frequency in patients with endometrial cancer, offers an opportunity for their early detection.
