This predictive computational cancer model utilizes over 3,000 complete patient histories to offer patient-specific predictions for colorectal cancer risk. The model, based on a semi-mechanistic approach, considers factors such as age, gender, symptoms, previous test results, and procedure conditions to enhance CRC surveillance post-screening colonoscopy. Research questions include exploring the impact of colonoscopy preparation quality on clinic burden, patient costs, CRC risks, and the cost-effectiveness of follow-up guidelines.
