2、男性是女性1.9倍）中国胃癌世界人口调整死亡率(mortality rates adjusted by the world population)男性：40.8/10 万，女性：18.6/10 万，分别是欧美发达国家的4.2-7.9 倍，3.8-8.0 倍有明显的地区差异和城乡差别。全国抽样调查263个点，胃癌调整死亡率在2.5-153.0/10万之间，Urban areas:15.3/10 万;Rural areas:24.4/10万，是城市的1.6 倍,NCCN共识分类,1类：基于高水平的证据，NCCN达成共识，推荐应用2A类：基于包括临床经验在内的稍低水平证据，NCCN达成共识，推荐应用

3、。2B类：基于包括临床经验在内的稍低水平证据，NCCN未达成统一共识（但无较大分歧）。3类：NCCN对该建议的适宜性存在较大分歧。除非特别说明，本指南中所有的建议均达成2A类共识。,NCCN 胃癌临床实践指南 2008第1版指南更新主要变化总结,（GAST-1）：workup：PET/CT扫描和EUS作为可选的检查项目。（GAST 2）：要求多学科会议讨论患者所有三个治疗途径的抉择 T2以上分期患者将术前化疗作为一类推荐首选治疗手段。术前放化疗作为2B类的首选治疗手段。（GAST3）：R0术后分期T2 N0M0及以上者，如术前采用ECF方案化疗，术后可选择ECF继续（1类）（GAST5）：fo

5、评估和协作！,多学科综合治疗模式有益于局部进展期胃癌患者（1类证据）NCCN专家组基本观点：不鼓励单一学科成员单方面进行治疗决策。具备以下条件，可能给局部进展期胃癌患者以最佳的综合治疗：例会形势实用（一周或2周一次），相关学科的机构和个人定期来共同回顾患者的详细资料。每次例会，各相关学科都要积极参与，包括肿瘤外科，肿瘤内科，消化科，放射科，病理科。此外，最好还能包括营养科，社工，护理以及其他支持学科。所有长期的治疗策略要在全面分期检查完成后再进行，最好在所有治疗开始之前。决策前共同回顾原始的医学数据而非单纯阅读报告。多学科团队做出共识推荐并摘要记录在案，对每位患者是有益的。特定患者的主要治疗小

6、组或医生应尊重以及考虑多学科团队所做出的共识推荐。反馈部分患者的治疗随访结果，对整个多学科团队是有效的实例教育方式。在例会期间，正式的定期复习相关文献，对整个多学科团队是高效的教育方式。,分期CT扫描EUS判断病灶范围腹腔镜有助于部分患者的分期不能根治性切除标准局部进展期:3/4站淋巴结转移,大血管受侵或被包绕远处转移或腹膜种植(包括腹腔脱落细胞学阳性可切除肿瘤T1者在有经验者可采用内镜下胃粘膜切除T1-T3合适的肿瘤切缘4 cm（5 cm）,镜下阴性推荐D1/D2淋巴结清扫,应至少检查15个淋巴结，并结合位置清扫到2站淋巴结 T4应切除受累部位不做常规脾切除,除非脾脏受累或脾门受侵可考虑留置
