概述

原发性胃淋巴瘤占胃恶性肿瘤的2%~7%,占胃肉瘤的70%~80%,占全身恶性淋巴瘤的2.4%。该病可见于任何年龄,45-60岁居多,男性较女性偏多。病因不清,可能与HP感染有关。 病理分为霍奇金病和非霍奇金淋巴瘤两种类型,后者占绝大多数,以B淋巴细胞为主。多见于胃中部小弯侧和后壁,始于胃粘膜相关淋巴样组织,逐渐向四周蔓延并侵犯全层。瘤体两面的粘膜或浆膜可隆起但外观完整,随着病情进展粘膜表面可形成溃疡、出血或侵透胃壁全层致穿孔。恶性淋巴瘤以淋巴转移为主。 临床表现临床上以上

Primary gastric lymphoma (PGL) is the most common extranodal non-Hodgkin lymphoma and the second most common gastric malignancy following adenocarcinoma.1 Epidemiological studies conducted in early 1990s supported the association between PGL and Helicobacter pylori (H. pylori) infection.2, 3 It is also believed that microbial genetic factors such as cytotoxin-associated antigen A (cag A) in addition to host genetic or environmental elements would affect the development of  PGL.4 Although it is known that PGL accounts for only 3–5% of malignant gastric tumours,4 this proportion may be varied according to the regional H. pylori prevalence or strains considering the report from northern Italy where the incidence of PGL was 10 times higher than that in the United Kingdom.

原发性胃淋巴瘤(PGL)是最常见的结外非霍奇金淋巴瘤,也是继腺癌之后第二常见的胃恶性肿瘤.120世纪90年代早期进行的流行病学研究支持了PGL与幽门螺杆菌(幽门螺杆菌)感染之间的关联.2,3 人们还认为微生物遗传因素如细胞毒素相关抗原A(cag A)除宿主遗传或环境因素外,还会影响PGL的发展.4虽然已知PGL仅占恶性的3-5% 考虑到来自意大利北部的报告,PGL的发病率比英国高10倍,根据区域幽门螺旋杆菌的患病率或菌株,这一比例可能会有所不同。
