胃癌和甲状腺疾病相关性研究进展

胃癌是我国常见的恶性肿瘤之一。多种因素与胃癌的发生相关，如环境、饮食、幽门螺杆菌感染、慢性萎缩性胃炎和肠上皮化生等。随着对胃癌研究的深入，国外学者发现胃癌的发病率在碘摄入不足或者摄入过多的地区有逐渐增高的趋势，而碘是甲状腺疾病发病的重要因素。最新的研究发现，胃癌和甲状腺疾病的关系可能受到地域因素的影响，但目前缺乏对此关系的大样本临床研究。本文试对这些研究的最新进展作一综述。

The research progress of the relationship between gastric carcinoma and thyroid disease

Gastric carcinoma is one of the most common malignant tumors in China. There are well-known risk factors for gastric cancer such as environment, foods, Helicobacter pylori infection of the stomach, chronic atrophic gastritis and intestinal metaplasia. With the in-depth study of gastric cancer, domestic and foreign scholars have found that there may be an association between gastric carcinoma and other diseases. Studies have shown that gastric carcinoma may be more prevalent in iodine-deficient or iodine-excess areas. And the iodine is the well-known risk factors for the thyroid disease. However, recent research has indicated that this relationship may be affected by region, in the same time a lot of clinical research about it has lacked. This article wants to summarize about it.
