中文摘要：

规范化的病理诊断报告对于胃癌进行准确TNM分期、预后判断及治疗具有重要指导意义。目前,胃癌规范化病理诊断主要以美国癌症联合委员会（AJCC）与国际抗癌联盟（UICC）联合制定的第7版恶性肿瘤TNM分期、日本第14版《胃癌处理规约》以及我国原卫生部2011年版《胃癌诊疗规范》为基础,主要包括内镜黏膜下剥离术（endoscopic submucosal dissection,ESD）标本、手术切除标本及新辅助治疗后标本的病理学规范化描述、取材及病理学诊断流程。

Standardized pathology reports play a very important role in accurate TNM staging, prognosis evaluation and treatment of gastric cancer. At present, standardized pathologic diagnosis of gastric cancer is mainly based on the AJCC UICC 7th TNM Classification of Malignant Tumor,Japanese Classification of Gastric Carcinoma： 14 th edition and Chinese Guidelines for Gastric Cancer Diagnosis and Treatment： 2011 version. The standardized pathological diagnostic process mainly includes pathological description,gross sampling and pathological diagnosis of the different samples （including ESD sample, gastrectomy sample and gastrectomy sample after neoadjuvant therapy）.
