This study aimed to evaluate the participation and follow-up test compliance rates and key performance indicators of the National Cancer Screening Program (NCSP) for colorectal cancer (CRC) from 2004 to 2017.
The overall outcomes of the NCSP for CRC were analyzed using the NCSP data collected from 2004 to 2017 and the Korean Central Cancer Registry for CRC from 2005 to 2017. We cross-sectionally analyzed the participation and follow-up test compliance rates and performance indicators for each year. The trend of participation rates as an annual percentage change was assessed, and other statistical analyses were performed.
The screening participation rates increased from 7.3% in 2004 to 30.5% in 2017. Additionally, the screening rates were higher among individuals aged 60-69 years and National Health Insurance Service beneficiaries of low-income status. However, the adherence to the follow-up test decreased from 63% in 2004 to 32% in 2017. The follow-up tests using the double-contrast barium enema method decreased from 42.2% in 2004 to 0.3% in 2017. However, follow-up tests by colonoscopy increased from 21.0% in 2004 to 31.8% in 2017. Furthermore, the positivity, false-positive, and interval CRC rates decreased, whereas the specificity increased from 2004 to 2016, indicating improved performance of CRC.
The participation rates and performance of the NCSP for CRC have steadily improved, whereas adherence to follow-up tests has decreased. Additionally, there is a rapid growth in colonoscopy volume as a follow-up test. Continued efforts are required to improve the follow-up rates.
本研究旨在评估 2004 年至 2017 年国家癌症筛查计划（NCSP）在结直肠癌（CRC）中的参与率和随访检测依从率以及关键绩效指标。
使用 2004 年至 2017 年期间收集的 NCSP 数据和 2005 年至 2017 年期间的韩国中央癌症登记处的 CRC 数据，分析 NCSP 对 CRC 的总体结果。我们对每年的参与率和随访检测依从率及绩效指标进行了横断面分析。评估了参与率作为年度百分比变化的趋势，并进行了其他统计分析。
2004 年筛查参与率为 7.3%，2017 年增至 30.5%。60-69 岁和低收入的国家健康保险服务受益人群的筛查率更高。然而，2004 年随访检测依从率为 63%，2017 年降至 32%。2004 年双重对比钡灌肠法的随访检测率为 42.2%，2017 年降至 0.3%。然而，2004 年结肠镜检查的随访检测率从 21.0%增加到 2017 年的 31.8%。此外，CRC 的阳性率、假阳性率和间隔期率降低，特异性从 2004 年到 2016 年增加，表明 CRC 的性能得到改善。
NCSP 对 CRC 的参与率和性能稳步提高，而随访检测的依从性下降。此外，作为随访检测的结肠镜检查量迅速增加。需要继续努力提高随访率。
