第15版日本胃癌处理规约外科修订主要集中在幽门下(No.6)淋巴结,将No.6细化为N.6a、No.6v、No6i。建议将上一版有明确腹膜转移者(P1)细化为P1a、P1b、P1c及P1x。特别强调了肿瘤浸润十二指肠的治疗原则。全球重要的胃癌临床研究中包括了13项来自我国的研究,涵盖了腹腔镜手术、新辅助化疗、术后辅助化疗、围手术期放化疗、腹腔热灌注化疗以及复发转移胃癌的三线抗血管治疗等。国际抗癌联盟及美国癌症联合会胃癌分期项目收集了全球17个国家的25 411例随访数据,建议在第8版TNM分期中Ⅲ期做适当调整。局部进展期胃癌的转化治疗取得了令人瞩目的成绩,将于不久发表的凤凰研究可为制定有关腹膜转移癌的治疗指南提供依据。
The 15th revision of the Japanese stomach cancer protocol surgical revision mainly concentrated in the pylorus (No.6) lymph nodes, No. 6 is refined to N.6a, No.6v, No6i. It is recommended that the previous version of clear peritoneal metastasis (P1) is refined into P1a, P1b, P1c and P1x. Special emphasis is placed on the principle of treatment of tumor infiltration of the duodenum. The world’s most important gastric cancer clinical study includes 13 studies from our country that cover laparoscopic surgery, neoadjuvant chemotherapy, postoperative adjuvant chemotherapy, perioperative radiotherapy and chemotherapy, intraperitoneal hyperthermic chemotherapy, and third-line anti-vascular therapy for recurrent and metastatic gastric cancer Wait. The International Union Against Cancer and the American Cancer Society Gastric Cancer Staging Project collected 25,411 follow-up data from 17 countries around the world and recommended that adjustments be made in phase III of the 8th edition of the TNM staging. The progress of the treatment of locally advanced gastric cancer has made remarkable achievements, will be published in the near future Phoenix research guidelines for the development of treatment of peritoneal metastases provide the basis.
