The Japanese Breast Cancer Society (JBCS) registry began data collection in 1975, and it was integrated into National Clinical Database in 2012. As of 2016, the JBCS registry contains records of 656,896 breast cancer patients from more than 1400 hospitals throughout Japan. In the 2016 registration, the number of institutes involved was 1422, and the total number of patients was 95,870. We herein present the summary of the annual data of the JBCS registry collected in 2016. We analyzed the demographic and clinicopathologic characteristics of registered breast cancer patients from various angles. Especially, we examined the registrations on family history, menstruation, onset age, body mass index according to age, nodal status based on tumor size and subtype, and proportion based on ER, PgR, and HER2 status. This report based on the JBCS registry would support clinical management for breast cancer patients and clinical study in the near future.
日本乳腺癌学会（JBCS）注册系统于 1975 年开始收集数据，并于 2012 年纳入国家临床数据库。截至 2016 年，JBCS 注册系统包含了来自日本各地 1400 多家医院的 656896 名乳腺癌患者的记录。在 2016 年的登记中，参与的机构数量为 1422 个，患者总数为 95870 人。本文总结了 2016 年 JBCS 注册系统收集的年度数据。我们从多个角度分析了登记的乳腺癌患者的人口统计学和临床病理特征。特别是，我们根据家族史、月经、发病年龄、年龄相关的体重指数、基于肿瘤大小和亚型的淋巴结状态以及基于 ER、PgR 和 HER2 状态的比例，对登记情况进行了检查。本报告基于 JBCS 注册系统，将为乳腺癌患者的临床管理和近期的临床研究提供支持。
