Hereditary colorectal cancer: risk assessment and management.
There are at least nine major cancer susceptibility syndromes that infer an increased risk for colorectal cancer and/or colorectal polyposis; hereditary nonpolyposis colorectal cancer syndrome, Muir-Torre syndrome, Turcot syndrome, the I1307K polymorphism of the APC gene, familial adenomatous polyposis, attenuated familial adenomatous polyposis, Peutz Jeghers syndrome, juvenile polyposis, and the PTEN hamartoma tumor syndrome. As a result, the differential diagnosis of hereditary colorectal cancer can be complex. In addition, there has been a dramatic increase in the knowledge available regarding risk assessment and management of hereditary colorectal cancer syndromes. The literature was reviewed to develop this concise review of the hereditary colorectal cancer syndromes to facilitate the accurate diagnosis of each syndrome and the appropriate medical care for individuals with these diagnoses. Referral to a qualified Clinical Cancer Genetics program is appropriate if any of these syndromes is suspected and they will ensure the most up-to-date information is available to the patient, their family, and their health care professionals.
