The guideline outlines different surveillance schedules, and offers recommendations for surveillance based on factors including: underlying risk for recurrence, patient comorbidity, and the ability to tolerate major surgery to resect recurrent disease or palliative chemotherapy, performance status, physiologic age, preference, and compliance.

This clinical practice guideline discusses the use of endoscopy for the evaluation and management of inflammatory bowel disease (IBD), with a review of endoscopic approaches for general management of IBD and recommendations for screening and surveillance of colorectal cancer. Timing of screening colonoscopy and surveillance intervals are reviewed, and surveillance procedures are discussed with comparisons made between random biopsies, white light biopsy, and surface chromoendoscopy. The guideline also provides recommendations on the management of abnormal findings including endoscopically visible lesions and dysplasia. Additional topics of interest include pouch surveillance and stricture evaluation and dilation.

This is a clinical practice guideline for patients diagnosed with or at risk of hereditary gastrointestinal cancer syndromes including lynch syndrome, familial adenomatous polyposis (FAP), attenuated familial adenomatous polyposis (AFAP), MUTYH-associated polyposis (MAP), Peutz–Jeghers syndrome, juvenile polyposis syndrome, Cowden syndrome, serrated (hyperplastic) polyposis syndrome, hereditary pancreatic cancer, and hereditary gastric cancer. The guideline reviews initial assessment, genetic testing for a germline mutation when indicated, pre- and post-test genetic counselling, and management of patients who meet clinical criteria for a syndrome as well as those with identified pathogenic germline mutations. Outcomes of interest include cancer risk, quality of life, and survival benefit from surveillance.

A clinical practice guideline for the use of colorectal endoscopic submucosal dissection and endoscopic mucosal resection in patients with colorectal cancer. The guideline examines diagnostic indications, perioperative diagnosis, treatment techniques, and postoperative care. Outcomes of interest include recurrence, curability, and delayed bleeding/perforation.
