胃癌的发病率因群体差异而有明显不同。经研究认为胃癌的病原学具有遗传因素。胃癌患者的亲属及 A 型血人中患这种恶性肿瘤的数量略高于其他人群。在发现其他类型肿瘤患者的 Hp1和 GC2-2增高的同时,发现胃癌患者的 Hp2-2频率也有增高。在一次研究中还发现 C3~*F 与肾腺癌有关,但这种关系还没有被认定。本文主要论述 Hp、GC 和 C3血清蛋白类型与胃癌之间的关系。 The incidence of gastric cancer varies significantly due to population differences. The study found that the etiology of gastric cancer has genetic factors. The number of such malignant tumors in relatives of gastric cancer patients and type A blood was slightly higher than that in other populations. When Hp1 and GC2-2 were found to increase in patients with other types of cancer, the frequency of Hp2-2 in gastric cancer patients was also increased. In one study, C3~*F was also found to be associated with renal adenocarcinoma, but this relationship has not yet been established. This article focuses on the relationship between Hp, GC, and C3 serum protein types and gastric cancer.
