Prognostic factors in the treatment of gastric mucosal atypical hyperplasia by endoscopic submucosal dissection.

<bold>Background: </bold>Endoscopic submucosal dissection (ESD) is becoming increasingly popular as a treatment for precancerous lesions and early cancers of the stomach. However, there have been few studies on the factors associated with the recurrence of precancerous lesions after ESD.<bold>Methods: </bold>To investigate the prognostic factors of gastric intraepithelial neoplasia, we retrospectively analyzed 115 patients who were treated with ESD between February 2018 and January 2020. Chi-square test and Fisher's extract test were used to select factors for further investigation, and prognostic analysis was carried out with the Kaplan-Meier method and a Cox regression model.<bold>Results: </bold>Platelet counts (P = 0.027) and albumin levels (P = 0.011) were both lower in patients with recurrence than in patients without recurrence of gastric mucosal atypical hyperplasia after ESD.<bold>Conclusions: </bold>This study reveals that low platelet counts and albumin levels were probably unfavorable prognostic factors in mucosal atypical hyperplasia of the stomach.
