21例早期胃癌患者的临床病理特点

目的分析早期胃癌的临床病理特点。方法选择本院21例经内镜活检及病理诊断为胃癌、手术后病理确诊为早期胃癌的患者，分析并总结其内镜下的特点、部位及病理类型。结果21例患者中，病灶位于胃窦12例，胃体4例，胃角4例，胃底1例。早期胃癌镜下分型中，Ⅰ型1例，Ⅱ型12例，Ⅲ型8例。黏膜内癌13例，黏膜下层癌8例，其中黏膜内癌淋巴结转移2例，黏膜下层癌淋巴结转移1例；高、中低分化管状腺癌10例，腺癌6例，印戒细胞癌4例及乳头状腺癌1例。结论内镜检查是诊断早期胃癌的首选方法，增强对内镜表现及病理认识，有助于提高早期胃癌检出率。

Clinical Pathological Characteristics of 21 Cases of Patients with Early Gastric Cancer

OBJECTIVE To analyze the clinical pathological characteristics of early gastric cancer. METHODS 21 patients with early gastric cancer diagnosed by endoscopic biopsy, pathology and postoperative pathology were selected. Their endoscopic characteristics, parts and pathological types were analyzed and summarized. RESULTS Among 21 patients, there were 12 cases with lesions in gastrc antrum, 4 in gastric body, 4 in gastric angle and 1 in gastric fundus. With regard to the classification of early gastric cancer, there was 1 at type I, 12 for II and 8 for III. A total of 13 and 8 patients respectively suffered from intramucosal cancer and submucosal cancer, in which 2 with intramucosal cancer and 1 with submucosal cancer occurred lymph node metastasis. There were 10 patients with highly, moderately and lowly-differentiated canalicular adenoma, 6 with adenocarcinoma, 4 with signet-ring cell carcinoma and 1 with polypoid adenocarcinoma. CONCLUSIONS Endoscopy is an optimal method to diagnose the early gastric cancer, hence enhancing endoscopic manifestations and pathological cognition are conductive to improving the detection rate of early gastric cancer.
