Trends in high-risk rates and screening rates for the population-based cancer screening program on esophageal, stomach and liver cancer in China, 2010-2016

Abstract

BackgroundA population-based cancer screening program in rural China, targeting three types of cancer that are most prevalent in these areas, including esophageal, stomach, and liver cancer was awarded by the government in China since 2007. A two-step design with cancer risk assessment based on questionnaire interview and HBsAg test strip and subsequent clinical intervention for high-risk populations was adopted with free of charge at the local hospitals designated in the program. The participate rate including high-risk rates and screening rates was important to find appropriate strategies to improve the overall awareness of the program. MethodsData from the cancer screening program between 2010 and 2016 were used to calculate higher rate (high-risk population/ participants recruited) and screening rate (participants received screening/ high-risk population). ResultsFrom 2010 to 2016, 1,637,429 residents were recruited in the program and filled the questionnaires, 350,646 (21.4%) for esophagus cancer, 273,715 (16.7%) for stomach cancer and 1,013,068 (61.9%) for liver cancer. 471,974 participants were assessed as high-risk population including 114,786 (24.3%) high risk for esophagus cancer, 161,809 (34.3%) high risk for stomach cancer and 195,379 (41.4%) high risk for liver cancer, respectively. 249,185 (52.8%) participants who were assessed as high risk received clinical screening. There were 64,710 (26.0%) for esophagus cancer screening, 71,365 (28.6%) for stomach cancer screening and 113,110 (45.4%) for liver cancer screening, respectively. ConclusionOur findings will provide important references for designing effective population-based screening strategies to enhance the screening acceptance by health action plan in the future.
