Secondary Malignancies In Long-Term Ovarian Cancer Survivors: Results Of The 'Carolin Meets Hanna' Study

ObjectiveTo evaluate the rate of secondary malignancies in long-term survivors with ovarian cancer.MethodsLong-term survivors with ovarian cancer (survival >= 8 years after initial diagnosis) with multiple malignancies were identified within the Tumorbank Ovarian Cancer and our study 'Carolin meets HANNA - Holistic Analyses of Long-term Survivors with Ovarian Cancer'.ResultsOf a total of 225 long-term survivors with ovarian cancer, 36 patients (16%) had at least one more cancer diagnosis before, concomitant with, or after, ovarian cancer. Median age was 52.5 years (range 37-79). A total of 60% were diagnosed with stage III/IV and most tumors were high-grade (88.6%), as well as of serous histology (63.9%). Median overall survival was 10 years (range 8-19). Secondary cancer after ovarian cancer was found in 17 long-term survivors (7.6%). Breast cancer was the most frequent secondary malignancy. Median duration between diagnosis of primary ovarian cancer and secondary cancer diagnosis was 78.5 months (range 12-220). BRCA was tested in 11 patients with seven patients being BRCA1 and one patient BRCA2 positive. Secondary cancers were detected by screening in 35.3% and self-detected in 29.4% of patients (breast self-examination).ConclusionA secondary malignancy was diagnosed in 7.6% of long-term survivors. Routine follow-up and cancer screening should be performed in long-term ovarian cancer survivors.
