胃黄色瘤与胃癌及其癌前病变相关性的研究进展

Progress of Research on Correlation Between Gastric Xanthoma and Gastric Cancer and Precancerous Lesions

胃黄色瘤又称胃黄斑瘤或胃脂质岛,是一种发生于胃黏膜的脂肪沉积型良性病变。其病因和发病机制尚不完全明确,可能与胃黏膜损伤修复、肠化生、脂质代谢异常有关。胃黄色瘤可发生于胃任何部位,常见于胃窦和幽门区。据报道,胃黄色瘤与早期胃癌风险增加相关。本文就胃黄色瘤与胃癌及其癌前病变相关性的研究进展作一综述。

Gastric xanthoma,also known as gastric macular tumor or gastric lipid island,is a benign lesion that occurs in the gastric mucosa as a result of fatty deposits.Its etiology and pathogenesis are not yet clear,and may be related to gastric mucosal damage and repair,intestinal metaplasia,and abnormal lipid metabolism.Gastric xanthoma can be seen in any part of the stomach,usually in gastric antrum and pylorus region.Gastric xanthoma is reported to be associated with increased risk of early gastric cancer.This article reviewed the progress of research on correlation between gastric xanthoma and gastric cancer and precancerous lesions.
