Genetic risk factors, diagnostic assessment including imaging and pathology, and treatment are discussed. Special topics of interest include genetic risk factors and association of NETs with carcinoid heart disease (CHD). Outcomes of interest include survival rates, sensitivity of diagnostic testing procedures, adverse effects and quality of life.

This is a clinical practice guideline for adults aged 19 and over. The guideline examines surveillance colonoscopy after polypectomy or curative resection for colorectal cancer, and in inflammatory bowel disease. Advances in colonoscopy, CT colonography, and other methods of investigation are also discussed, as well as psychosocial effects of colonoscopy and socioeconomic factors. Outcomes of interest include survival, patient experience, and accuracy of colonoscopy.

This is a clinical and professional practice guideline that recommends standards of best practice for the use of CT colonography in the screening and diagnostic assessment of colorectal cancer. The guideline discusses patient information and consent, CT technique, patient experience and safety, and interpretation of results. Additional topics include radiologist training/assessment, use of endoscopy as a post-CT test, and resource allocation.

This is a clinical practice guideline for adults with average or high risk for colorectal cancer. The guideline discusses risk factors for colorectal cancer, effectiveness of screening tests, and screening strategies based on age and risk. The following screening techniques are compared: high-sensitivity guaiac fecal occult blood test (gFOBT), immunochemical fecal occult blood test (iFOBT/FIT), flexible sigmoidoscopy, colonoscopy, standard guaiac FOBT (gFOBT), air contrast barium enema, CT colonography, and fecal DNA testing. Outcomes of interest include colon cancer incidence, morbidity, and mortality, as well as outcomes of screening intervention including test effectiveness and adverse effects.

This is a clinical practice guideline for patients requiring colon cancer screening, examining colonoscopy standards. Important aspects include ideal polyp detection conditions, monitoring during the procedure, and follow-up care.
