Abstract

Objective: To study the features of gastric neuroendocrine tumors (NETs) and the diagnostic and prognostic significance of PDX-1 expression in them.

Material and methods: 207 NETs identified in 56 men and 115 women (59 had multiple NETs), and 94 cases of gastric cancer (comparison group) were studied morphologically and immunohistochemically.

Results: In more than half of the cases (54.93%), NETs were localized in the body of the stomach; the cardiac and antral parts of the stomach accounted for 8.64% and 11.73%, respectively. NETs of the cardiac region predominated in men, and of the body and antrum - in women. NETs of the cardiac region predominated in men, and of the body and antrum - in women. The vast majority of NETs were highly differentiated (89.20%), of which Grade 1, 2 and 3 were 55.41%, 40.76% and 3.82%, respectively. Neuroendocrine carcinomas (NEC) accounted for 10.80% of all NET cases. NECs were more often localized in the cardiac part of the stomach and accounted for 35.71% of all NETs in the cardiac part. The share of NEC among all NETs of the antrum was 15.79%, of the body of the stomach - only 3.37%. Metastases were found in 17.90% of NETs. Expression of PDX-1 was detected in 44.73% of NETs, 70% of NECs and 74.50% of gastric cancers.

Conclusion: PDX-1 is involved in the mechanisms of precancerous and cancerous lesions of the stomach and its overexpression is detected in the majority of the most malignant NETs and gastric cancers.

[胃神经内分泌肿瘤的特征与 PDX-1 转录因子的表达】。］

摘要研究胃神经内分泌肿瘤（NET）的特征以及PDX-1在其中表达的诊断和预后意义。材料与方法：对56名男性和115名女性（59人患有多发性NET）的207例NET以及94例胃癌（对比组）进行形态学和免疫组化研究：超过一半的病例（54.93%）的NET位于胃体；胃的心区和前区分别占8.64%和11.73%。心脏部位的NET以男性居多，胃体和胃窦部位的NET以女性居多。男性以心脏部位的NET为主，女性则以胃体和胃窦部位的NET为主。绝大多数NET属于高分化癌（89.20%），其中1级、2级和3级分别占55.41%、40.76%和3.82%。神经内分泌癌（NEC）占所有NET病例的10.80%。NEC多发于胃的心脏部位，占心脏部位所有NET的35.71%。在胃窦部的所有 NET 中，NEC 占 15.79%，而在胃体中仅占 3.37%。17.90%的NET发现了转移。44.73%的NET、70%的NEC和74.50%的胃癌都检测到了PDX-1的表达：结论：PDX-1参与了胃癌前病变和癌变的发生机制，在大多数恶性NET和胃癌中都检测到了PDX-1的过表达。
