Second malignant neoplasms were evaluated among 32,251 women with ovarian cancer, including 4,402 10-year survivors, within the nine population-based registries of the Surveillance, Epidemiology, and End Results Program of the National Cancer Institute (1973-1992) and the Connecticut Tumor Registry (1935-1972).
Overall, 1,296 second cancers occurred against 1,014 expected [observed/expected (O/E), 1.28 ; 95% confidence interval (CI), 1.21-1.35]. Sites contributing 25 or more excess cancers included leukemia (O/E, 4.17 ; O, 111 ; 95% CI, 3.43-5.03) and malignancies of colon (O/E, 1.33 ; O, 188 ; 95% CI, 1.15-1.54), rectum (O/E, 1.43 ; O, 76 ; 95% CI, 1.13-1.79), breast (O/E, 1.18 ; O, 404 ; 95%, CI 1.07-1.30), and bladder (O/E, 2.07 ; O, 65 ; 95% CI, 1.59-2.63).
Ocular melanoma (O/E, 4.45 ; O, 8 ; 95% CI, 1.92-8.77) was also significantly increased.
Second cancer risk was high during all follow-up intervals, and cumulative risk at 20 years was 18.2%, compared with a population expected risk of 11.5%. Statistically significant relationships existed between serous adenocarcinoma of the ovary and breast cancer (O/E, 1.29 ; 95% CI, 1.06-1.56) and mucinous ovarian adenocarcinoma and rectal cancer (O/E, 1.95 ; 95% CI, 1.09-3.22).
Secondary leukemia appeared linked with antecedent chemotherapy, whereas radiotherapy was associated with cancers of connective tissue, bladder, and possibly pancreas.
