Background

In Japan, comprehensive cancer statistics data have been collected through national cancer registries, but these data are rarely summarized and reported in research articles.

Methods

Here, we compiled the national registry data on malignant tumors originating from gynecologic organs (ovary, corpus uteri, cervix uteri) in Japan.

Results

The number of new patients in 2019 was 13,380, 17,880, and 10,879, respectively, and the number of deaths in 2021 was 5081, 2741, and 2894, respectively. Compared with 40 years ago, the incidence of ovarian cancer has tripled, the incidence of uterine corpus cancer (mainly endometrial cancer) has increased eightfold, the mortality rate of uterine corpus cancer has tripled, and the incidence of cervical intraepithelial cancer has increased ninefold in data standardized by the world population. Compared with the United States, the incidence rate of ovarian cancer has overtaken and the mortality rate of uterine corpus cancer is the same, while both the incidence and mortality rates of cervical cancer are higher in Japan.

Conclusion

The incidence of gynecologic cancer is increasing significantly in Japan.

日本妇科癌症趋势：1980年至2019年的发病率和1981年至2021年的死亡率

背景

在日本，通过国家癌症登记处收集了全面的癌症统计数据，但这些数据很少在研究文章中进行总结和报告。

方法

在此，我们整理了日本源自妇科器官（卵巢、子宫体、子宫颈）的恶性肿瘤的国家登记数据。

结果

2019年新增患者数分别为13380例、17880例和10879例，2021年死亡例数分别为5081例、2741例和2894例。与40年前相比，卵巢癌的发病率增加了3倍，子宫体癌（主要是子宫内膜癌）的发病率增加了8倍，子宫体癌的死亡率增加了3倍，宫颈上皮内癌的发病率增加了9倍。由世界人口标准化的数据。与美国相比，卵巢癌的发病率已超过，子宫体癌的死亡率与之相当，而日本的宫颈癌的发病率和死亡率均较高。

结论

在日本，妇科癌症的发病率正在显着增加。
