However, little has been reported on the survival of elderly patients aged 75 or older with gynecologicalcancer in Japan. Methods: To clarify survival in women aged 75 years or older with gynecological cancer, we analyzeddata of 4,089 gynecological cancer cases (cervical cancer, 1,309 cases; endometrial cancer, 1,319 cases; and ovariancancer, 1,461 cases) in patients aged 75 or older from 21 population-based cancer registries in Japan, diagnosed in2006-2008. We calculated the net survival (NS) of younger (75-79 years old), older (80-84 years old) and the oldestage group (85-99 years old). We also calculated NS stratified by extent of disease and histological type. Results: FiveyearNS of cervical cancer patients was 54.5% in the younger age group, 40.8% in the older age group and 28.2%in the oldest age group. Five-year NS of endometrial cancer patients was 64.5%, 51.6% and 39.0% in the younger,older and oldest age groups, respectively. Five-year NS of ovarian cancer was 34.7%, 18.8% and 8.3%, respectively.Conclusion: We estimated NS in elderly patients aged 75 years or older with gynecological cancers in Japan usingdata from population-based cancer registries.}, keywords = {survival,Epidemiology,Frail Elderly,Uterine Neoplasms,ovarian neoplasms}, url = {https://journal.waocp.org/article_82407.html}, eprint = {https://journal.waocp.org/article_82407_3d744c18165abb966b6c1a250598575f.pdf} }
