Hereditary Colorectal Cancer Syndromes: Role of Genetic Counselors and Gastroenterologists

Gastroenterologists are on the frontline of gastrointestinal cancer screening and prevention. Amongst gastroenterologists' large volume of patients, individuals at high-risk for a hereditary cancer syndrome are often identified based on their personal or family history of cancer and/or polyps. Gastroenterologists will benefit from collaborating with genetic counselors in particular to ensure that high-risk patients receive appropriate education, testing, and counseling. Genetic counselors are trained to assess cancer risk, provide personalized risk assessment and management recommendations, and counsel patients regarding the ethical and psychosocial implications of testing. In this partnership, gastroenterologists are responsible for identifying patients who fall into the category of high-risk; thereby, warranting additional evaluation and counseling. Genetic counselors are responsible for coordinating genetic testing, interpreting results, and recommending appropriate medical management options for the patient and his/her family. When implemented, this partnership benefits the patient and fulfills the medical, legal, and ethical responsibilities of both professional groups.
