AbstractCancer Public Library Database (CPLD) links data from four major population-based public sources: the Korea National Cancer Incidence Database in the Korea Central Cancer Registry, cause-of-death data in Statistics Korea, the National Health Information Database in the National Health Insurance Service, and the National Health Insurance Research Database in the Health Insurance Review & Assessment Service. The National Cancer Data Center has developed a new nationally representative sample cohort dataset from Korean Clinical Data Utilization for Research Excellence project (K-CURE) CPLD: Stomach Cancer Sample Cohort, Breast Cancer Sample Cohort, Colorectal Cancer Sample Cohort, and Liver Cancer Sample Cohort. The sample populations consisted of approximately 21% of all cancer patients from 2012 to 2019. The populations of the Stomach Cancer Sample Cohort, Breast Cancer Sample Cohort, Colorectal Cancer Sample Cohort, and Liver Cancer Sample Cohort were 51,951, 39,586, 53,485, and 27,375 patients, respectively. The dataset included cancer incidence information, demographics, socioeconomic variables, health utilization data (procedures, diagnoses, and medications), general health checkup data, cancer screening data before and after the cancer incidence, as well as death information. These cohorts could help researchers analyze time-to-event data on mortality, treatment outcomes, comorbid conditions following a cancer diagnosis, and cancer incidence risk factors. The data can be accessed through the K-CURE portal (https://k-cure.mohw.go.kr/).

SummaryKorean summary
국립암센터의 국가암데이터센터는 K-CURE 사업의 일환으로 암·공공라이브러리를 구축하고 위암, 유방암, 대장암, 간암 표본을 공개하였다. 암·공공라이브러리는 국립암센터의 암등록자료를 기준으로 건강보험심사평가원 명세서, 국민건강보험공단 자격 및 검진자료, 통계청 사망자료를 결합하여 구축한 것으로 사용하기 쉽게 암종별 표본을 공개하고 있다. 암등록자료는 발생일자, 요약병기, ICD-O-3 코드를 포함해 기존 청구자료보다 정확한 암 예후 등의 연구가 원격으로 가능하다. 이용자는 희망시 맞춤형 자료로도 신청 가능하다. 사용 신청은 https://k-cure.mohw.go.kr/ 에서 가능하다.Key Message
The National Cancer Data Center (NCDC) of the National Cancer Center(NCC) developed the Cancer Public Library Database (CPLD) under the Korean Clinical Data Utilization for Research Excellence project (K-CURE). CPLD is constructed by linking the NCC’s cancer registry data with claims data from the Health Insurance Review and Assessment Service, eligibility and health screening data from the National Health Insurance Service, and Cause-of-death data from Statistics Korea. The NCDC has opened sample cohorts for stomach, breast, colorectal, and liver cancers to promote cancer research with a remotely accessible environment. The data can be accessed through the K-CURE portal (https://k-cure.mohw.go.kr/).
