Using chatbots to screen for heritable cancer syndromes in patients undergoing routine colonoscopy.

Background: Hereditary colorectal cancer (HCRC) syndromes account for 10% of colorectal cancers but remain underdiagnosed. This feasibility project tested the utility of an artificial intelligence-based chatbot deployed to patients scheduled for colonoscopy to identify HCRC risk factors, educate participants about HCRC and obtain consent to genetic testing as an extension of genetic counselling of appropriate subjects. Genetic counsellor (GC) and genetic counselling assistant (GCA) time spent per subject was also measured.

The Clinical Spectrum of Mutations.

is a tumor suppressor gene that classically dampens the PI3K/AKT/mTOR growth-promoting signaling cascade. dysfunction causes dysregulation of this and other pathways, resulting in overgrowth. Cowden syndrome, a hereditary cancer predisposition and overgrowth disorder, was the first Mendelian condition associated with germline mutations.
