High frequency of gastric cancer precursor lesions in patients with gastric xanthelasma: a prospective case-control study.

OBJECTIVE An association of gastric cancer and precursor lesions with gastric xanthelasma has frequently been reported. However, the incidence of both gastric xanthelasma and gastric cancer precursor lesions increases with age. The aim of this study was to evaluate the frequency and characteristics of atrophic gastritis, intestinal metaplasia and dysplasia in patients with gastric xanthelasma compared to controls. MATERIAL AND METHODS Cases with gastric xanthelasma endoscopically and histopathologically were included in this prospective study. The patients included in the study were compared with age- and sex-matched controls in terms of the frequency and characteristics of atrophic gastritis, intestinal metaplasia, dysplasia and cancer. RESULTS In a series of 1892 upper endoscopies, 108 patients (5.7%) were found to have gastric xanthelasma. The average age of the patients was 61.41 ± 11.43 years. Among the patients, 58 (53.7%) were male. The frequencies of atrophic gastritis, intestinal metaplasia, dysplasia and gastric cancer in the xanthelasma group (n = 108) were 31.5, 68.5, 3.7 and 2.8%, respectively. The frequencies of atrophic gastritis, intestinal metaplasia, dysplasia and gastric cancer in the control group (n = 183) were 11.5, 31.7, 0.5 and 0.5%, respectively. Compared to the control group, the frequency of these cancer precursor lesions and the prevalence of advanced stage based on operative link on gastritis intestinal metaplasia assessment were found to be higher in the xanthelasma group (P < 0.05). CONCLUSION Gastric xanthelasma is associated with an increased frequency of gastric precancerous lesions and should be considered an important marker.
