Key clinical point: First-degree relatives of patients with gastric cancer show a high prevalence of preneoplastic lesions (PNL).
Major finding: The prevalence of PNL, atrophic gastritis, and intestinal metaplasia in first-degree relatives of gastric cancer patients were 86.4%, 82.7%, and 54.5%, respectively. The incidence of PNL was not significantly associated with sex (odds ratio [OR] 3.10; 95% confidence interval [CI] 1.00-9.64), age (OR 0.74; 95% CI, 0.26-2.14), and Helicobacter pylorii infection (OR 0.58; 95% CI 0.12-2.77). The advanced stages of Operative Link on Gastritis Assessment and Operative Link on Gastritis/Intestinal-Metaplasia Assessment were verified in 18.0% and 16.3% of the first-degree relatives, respectively.
Study details: This was a cross-sectional study including 110 first-degree relatives of patients with gastric cancer.
