Currently, its incidence rate is increasing at a rate of 4% per year, exceeding the global annual average growth rate. Screening and early diagnosis of colorectal cancer and precancerous lesions are key measures to reduce the disease burden of colorectal cancer in China. In previous clinical studies, colorectal cancer screening in high risk population received extensive attention. However, it cannot be ignored that the majority of sporadic colorectal cancers occur in the average risk population. Therefore, there is an urgent need to develop new approach for colorectal cancer screening in the average risk population in China.\n\nFecal Immunochemical Testing (FIT) initial screening followed by diagnostic colonoscopy is widely recommended by colorectal cancer screening guidelines worldwide. The current colorectal cancer screening approach faces challenges including limited sensitivity of initial screening technologies and insufficient population coverage in organized screening programs in China. Stool DNA tests detect DNA biomarkers of tumor cells in the stool and have higher sensitivity in detecting advanced colorectal neoplasms. USPSTF has recommended FIT-sDNA as initial screening tests in the average risk population. Colorectal Cancer Early Screening in China (Clear-C) trial has reported FIT-sDNA had higher sensitivity than FIT in detecting advanced colorectal neoplasms among high risk population, yet there is a lack of randomized controlled trials (RCTs) directly comparing the effectiveness of FIT and FIT-sDNA for colorectal cancer screening in the average risk population in China.\n\nIn China Colorectal Cancer Screening Trial 2 (C-Cost2), we propose to perform a multicenter, individual-level randomized, parallel group trial directly comparing FIT and FIT-sDNA in the average risk population in China. The main research hypothesis is that the screening protocol of FIT-sDNA group (Group B) has a superior detection rate of advanced colorectal neoplasms compared to the FIT group (Group A).', 'detailedDescription': 'This study intends to recruit participants who meet the above inclusion and exclusion criteria in China, with the goal of recruiting at least 7504 eligible participants at baseline. The study adopts an individual-level randomized design. After signing the informed consent form, eligible participants will be randomly assigned to 2 colorectal cancer screening groups. All participants will undergo a 4-year screening phase, and then all participants will be followed up for a long term. Fecal, blood, and tissue samples will be collected from the participants during the study. The grouping and specific intervention measures are as follows:\n\n1. FIT group (n = 3752): The internationally recommended screening protocol is adopted. In the first 4 years of the screening phase, all participants will receive annual FIT tests. Participants with positive FIT results are recommended to undergo diagnostic colonoscopy. Suspicious lesions detected during the colonoscopy will be resected and further sent for pathological examination. Participants who refuse FIT tests, have negative FIT tests, have positive FIT tests but do not receive diagnostic colonoscopy will be screened again in the first 4 years. All the participants will be followed by long-term follow-ups.\n2. FIT-sDNA group (n = 3752): A new screening protocol is adopted. In the first 4 years of the screening phase, all participants will receive annual FIT-sDNA tests. Participants with positive FIT-sDNA results are recommended to undergo diagnostic colonoscopy. Suspicious lesions detected during the colonoscopy will be resected and further sent for pathological examination. Participants who refuse FIT-sDNA tests, have negative FIT-sDNA tests, have positive FIT-sDNA tests but do not receive diagnostic colonoscopy will be screened again in the first 4 years.
