The Korean Breast Cancer Society (KBCS) has reported a nationwide breast cancer data since 1996. We present a comprehensive report on the facts and trends of breast cancer in Korea in 2013. Data on the newly diagnosed patients in the year 2013 were collected from 99 hospitals by using nationwide questionnaire survey. Clinical characteristics such as stage of cancer, histologic types, biological markers, and surgical management were obtained from the online registry database. A total of 19,316 patients were newly diagnosed with breast cancer in 2013. The crude incidence rate of female breast cancer including carcinoma in situ was 76.2 cases per 100,000 women. The median age at diagnosis was 50 years, and the proportions of postmenopausal women with breast cancer accounted for more than half of total patients. The proportion of early breast cancer increased consistently, and the pathologic features have changed accordingly. Breast-conserving surgery was performed in more cases than total mastectomy in the year. The total number of breast reconstruction surgeries markedly increased approaching 3-fold in last 11 years. According to annual percentile change of invasive cancer incidence, the incidence increased rapidly until 2010. And thereafter the increase of it became steadier. For ductal carcinoma in situ, the incidence consistently increased during the same period without any joinpoint. Analysis of nationwide registry data will contribute to defining of the trends and characteristics of breast cancer in Korea.
韩国乳腺癌协会（KBCS）自1996年起开始报告全国范围内的乳腺癌数据。我们呈现一份关于2013年韩国乳腺癌实际情况和趋势的综合报告。2013年新诊断患者的数据是通过全国性问卷调查从99家医院收集而来。癌症分期、组织学类型、生物学标志物以及手术治疗等临床特征则从在线登记数据库中获取。2013年共有19316例患者被新诊断为乳腺癌。包括原位癌在内的女性乳腺癌粗发病率为每10万名女性中有76.2例。诊断时的中位年龄为50岁，绝经后乳腺癌女性患者的比例占总患者数的一半以上。早期乳腺癌的比例持续上升，病理特征也相应发生了变化。当年保乳手术的实施例数多于全乳切除术。在过去11年中，乳房重建手术的总数显著增加，接近原来的3倍。根据浸润性癌发病率的年度百分位数变化，发病率在2010年之前迅速上升，此后上升趋势趋于平稳。对于导管原位癌，在同一时期发病率持续上升且无任何转折点。对全国登记数据的分析将有助于明确韩国乳腺癌的趋势和特征。
