This clinical practice guideline provides recommendations on colorectal screening for patients with high-risk syndromes of inherited colon cancer. Recommendations are provided for management of Lynch syndrome, FAP, MAP, Peutz-Jeghers syndrome, juvenile polyposis syndrome (JPS), SPS, and other high-risk syndromes associated with CRC risk (Li-Fraumeni syndrome [LFS] and Cowden syndrome/PTEN hamartoma tumor syndrome [PHTS]). Topics of discussion include risk assessment and genetic counselling, diagnosis, and preventative treatment options.
This clinical practice guideline provides recommendations for follow-up care, surveillance protocol, and secondary prevention measures for survivors of colorectal cancer. The guideline addresses the following questions which include: what evaluations (e.g., colonoscopy, computed tomography [CT], carcinoembryonic antigen [CEA], liver function, complete blood count [CBC], chest x-ray, history, physical exam) should be performed for surveillance for recurrence of cancer? What is a reasonable frequency of these evaluations for surveillance? Which symptoms and/or signs potentially signify a recurrence of CRC and warrant investigation?
