This retrospective cohort study included all patients diagnosed with LS between 1/1/1997-12/31/2020 at Kaiser Permanente Northern California. Cumulative incidence of gastric cancer and small intestinal cancer was calculated using competing risk methodology.
Discussion: Patients with LS, particularly MSH2 and MLH1 PV carriers, had significantly increased lifetime risk of gastric and small intestinal cancer. Testing and treatment of H. pylori should be considered for all patients with LS.
