Abstract for: Improving colorectal cancer screening and care in low and middle-income countries: an example from Thailand

Colorectal cancer (CRC) is one of the major leading causes of cancer death worldwide. It is preventable and more curable in early detected patients by a CRC screening. However, incidence and mortality rate trend to be higher in low and middle-income countries (LMICs) including Thailand because the screening policy cannot reach enough population. In LMICs, Stool-based screening is used as primary screening and diagnostic cancer is performed for all population with positive results on stool-based screening. Constraint in colonoscopy capacity is one of major things that we need to concern for LMICs. Overused in stool-based screening can harm the system due to colonoscopy workload-capacity mismatch. Nevertheless, there is no previous article studying about benefits and harms from using screening policy in limited colonoscopy capacity using national data from LMICs. Stock and Flow Diagram was constructed to develop a specific set of policy to improve the effectiveness of CRC screening in LMICs context.
