Background: The number of elderly patients with gynecological cancer in Japan is increasing in line with the aging of society. However, little has been reported on the survival of elderly patients aged 75 or older with gynecological cancer in Japan. Methods: To clarify survival in women aged 75 years or older with gynecological cancer, we analyzed data of 4,089 gynecological cancer cases (cervical cancer, 1,309 cases; endometrial cancer, 1,319 cases; and ovarian cancer, 1,461 cases) in patients aged 75 or older from 21 population-based cancer registries in Japan, diagnosed in 2006-2008. We calculated the net survival (NS) of younger (75-79 years old), older (80-84 years old) and the oldest age group (85-99 years old). We also calculated NS stratified by extent of disease and histological type. Results: Five-year NS 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 using data from population-based cancer registries.
随着社会老龄化，日本老年妇科癌症患者数量不断增加。然而，关于日本75岁及以上老年妇科癌症患者的生存率报道较少。方法：为明确75岁及以上老年妇科癌症患者的生存率，我们分析了来自日本21个基于人群的癌症登记处的4089例75岁及以上妇科癌症病例（宫颈癌1309例、子宫内膜癌1319例、卵巢癌1461例）的数据，这些病例于2006 - 2008年被诊断。我们计算了较年轻组（75 - 79岁）、年长组（80 - 84岁）和最年长组（85 - 99岁）的净生存率（NS）。我们还按疾病范围和组织学类型分层计算了净生存率。结果：宫颈癌患者的5年净生存率在较年轻组为54.5%，在年长组为40.8%，在最年长组为28.2%。子宫内膜癌患者的5年净生存率在较年轻、年长和最年长组分别为64.5%、51.6%和39.0%。卵巢癌的5年净生存率分别为34.7%、18.8%和8.3%。结论：我们利用基于人群的癌症登记处的数据估计了日本75岁及以上老年妇科癌症患者的净生存率。
