我国75岁以上老年胃癌患者占全部胃癌新发病例和死亡病例数的21%和30%，其发病率和死亡率仅次于肺癌位居第2位。高龄胃癌患者具有临床表现不特异、胃上部癌比例高、肿瘤体积大、TNM分期晚等临床病理特点，同时具有共患疾病多、身体储备功能差等特征，发生手术相关并发症风险较高。因此，对此类患者的诊治应引起胃癌专科医生的高度重视。诊治过程需要多学科综合系统评估：对身体状态进行综合评估，对共患的基础疾病给予积极治疗和纠正；术前精准分期，推荐常规进行超声胃镜（EUS）检查，其对肿瘤T分期和N分期的准确度高于CT。以精准外科和加速康复外科理念为指导，进行个体化治疗：对淋巴结转移风险较低的早期胃癌，推荐按照扩大的适应证进行ESD切除；对进展期可切除胃癌，则主要为外科手术，依据切缘足够≥4 cm的基本原则和精准分期进行“缩小”手术，免气腹技术可推荐用于高龄老年胃癌患者腔镜手术；对进展期不可切除胃癌，除外化疗反应率极高患者，不优先推荐“转化治疗”，可行姑息化疗，若不能耐受，则推荐进行免疫治疗或最佳支持治疗。加速康复外科治疗手段在＞75岁的老年胃癌患者中的应用需要慎重选择。

The new cases and mortality of gastric cancer in the population aged over 75 years account for 21%and 30% of the cases in the whole population respectively. These elderly patients with gastric cancer are characteristic of nonspecific clinical manifestations, high proportion of upper gastric carcinoma, larger tumor size, advanced TNM stage, concomitant diseases, poor body function and high risk of complications. Specialists should pay more attention to the diagnosis and treatment of these patients. Comprehensive and systemic assessment should be performed, and concomitant diseases should be treated. Accurate preoperative staging should be accessed by EUS and CT. Individualized treatment according to the principle of precise surgery and enhanced recovery after surgery (ERAS) should be performed as follows. For early gastric cancer with low risk of lymph node metastasis, endoscopic submucosal dissection (ESD) is recommended for expanded indications. For resectable advanced gastric cancer , “downsizing” surgery obtaining≥ 4 cm incisal margin is recommended, which must be based on accurate preoperative stage. And gasless laproscopy is applicable for these patients. For unresectable advanced gastric cancer, conversion therapy is not the priority unless patients with high response rate. Palliative chemotherapy, immunotherapy and best supportive care should be applied in turn. ERAS techniques application in elderly patients with gastric cancer requires careful selection.
