Article Synopsis
  • Colorectal cancer (CRC) screening in China includes organized programs, opportunistic screening, and physical exams, but accurately measuring coverage rates is challenging.* -
  • As of 2020, organized screening programs had very low coverage rates of only 2.7% for those aged 40-74, with cumulative rates showing gradual improvement over the years.* -
  • The study indicates a total estimated screening coverage rate of 3.0% for the 40-74 age group, highlighting the need for enhanced access and more research on opportunistic screening methods.*

Background: Screening reduces colorectal cancer (CRC) burden by allowing early resection of precancerous and cancerous lesions. An adequate selection of high-risk individuals and a high uptake rate for colonoscopy screening are critical to identifying people more likely to benefit from screening and allocating healthcare resources properly. We evaluated whether combining a questionnaire-based interview for risk factors with fecal immunochemical test (FIT) outcomes for high-risk assessment is more efficient and economical than a questionnaire-based interview-only strategy.

Background & Aims: A one-size-fits-all approach to colorectal cancer (CRC) screening that does not account for CRC risk factors is not conducive to personalized screening. On the basis of the principle of equal management of equal risks, we aimed to tailor and validate risk-adapted starting ages of CRC screening for individuals with different CRC risk factors.

Methods: A multi-center community-based population cohort (N = 3,165,088) was used to evaluate the starting age of CRC screening with comprehensive consideration of risk factors.

Article Synopsis
  • - The study focused on estimating disability-adjusted life years (DALYs) for breast cancer in Chinese women, highlighting the significance of local disability weights over generic ones, showing that approximately 17.3% of DALYs in 2015 were due to years lived with disability (YLDs).
  • - Using various methods including prevalence modeling and mortality rates, the research projected that DALYs for breast cancer could rise by 26.7% by 2030 under unchanged screening conditions but could drop by 1.5% with increased screening coverage as per the "Healthy China Initiative."
  • - The findings indicate that the estimated DALYs in China are lower and have a higher proportion of YLDs compared to global estimates,

Over 40% of lung cancer cases occurred in never-smokers in China. However, high-risk never-smokers were precluded from benefiting from lung cancer screening as most screening guidelines did not consider them. We sought to develop and validate prediction models for 3-year lung cancer risks for never- and ever-smokers, named the China National Cancer Center Lung Cancer models (China NCC-LC models).

Background: Non-smokers account for a large proportion of lung cancer patients, especially in Asia, but the attention paid to them is limited compared with smokers. In non-smokers, males display a risk for lung cancer incidence distinct from the females-even after excluding the influence of smoking; but the knowledge regarding the factors causing the difference is sparse. Based on a large multicenter prospective cancer screening cohort in China, we aimed to elucidate the interpretable sex differences caused by known factors and provide clues for primary and secondary prevention.
