目的探讨早期胃癌患者的临床特征、内镜下表现、病理类型、病灶浸润深度及淋巴结、血管转移情况。方法选取101例早期胃癌患者，男74例，女27例。早期胃癌的诊断和分型根据日本胃癌研究会标准分为隆起型、平坦型和凹陷型。病理组织学分类采用WHO(2004年)分类法。标本均置4%甲醛液中固定，常规HE染色，切片，显微镜下观察。结果黏膜内癌42例，黏膜下层癌47例，侵及黏膜肌层12例，伴区域淋巴结转移14例，血管转移2例，神经转移2例。内镜分型：I型2例,II型80例,I I型19例。病理组织类型：印戒细胞癌41例，低分化腺癌40例，中分化腺癌16例，黏液腺癌4例。结论早期胃癌以胃窦为主，凹陷型早期胃癌临床上常见，大体形态以Ib、Ic、II型多见，组织学类型以印戒细胞癌及低分化腺癌为主，因此应重视内镜下早期胃癌好发部位和病变形态的仔细观察，有助于早期胃癌的检出率，从而改善胃癌预后。“,”Objective Investigate the clinical characteristics of patients with gastric cancer early,Endoscopic findings,Pathological type,Lesion depth of invasion and lymph node metastasis,Vascular.Methods 101 cases of early gastric cancer patients,male 74 cases,female 27 cases.Early gastric cancer diagnosis and classification according to the Japanese Gastric Cancer Research Association standards are divided into uplift type,flat type and depression type.Histopathological classification with WHO classification (2004).Specimens were fixed in 4%formaldehyde solution set,routine HE staining,sections were observed under microscope.Results 42 cases of intramucosal carcinoma,47 cases of submucosal carcinoma,invasion of the muscularis mucosa in 12 cases,14 cases with lymph node metastasis,vascular metastasis in 2 cases,2 cases of nerve transfer.Endoscopic classification:type I2 cases,type II80 cases,type IIin 19 cases.Pathological types:41 cases of signet ring cel carcinoma,40 cases of low dif erentiated adenocarcinoma,16 cases of moderately dif erentiated adenocarcinoma,4 cases of mucinous carcinoma.Conclusion Early gastric cancer in gastric sinus,depressed type early gastric cancer clinical y common, gross morphology in Ib,Ic,IItype rare,histological type is given priority to with signet ring cel carcinoma and poorly dif erentiated adenocarcinoma,so at ention should be paid to early gastric cancer, endoscopic predilection site and lesion morphology of careful observation,detection rate contribute to early gastric cancer,so as to improve the prognosis of gastric cancer.
