局部进展期胃癌规范化淋巴结清扫范围中国专家共识(2022版)

Chinese expert consensus on extent of standardized lymphadenectomy for locally advanced gastric cancer(2022 edition)

局部进展期胃癌(LAGC)应进行以手术为主的综合治疗。规范化的淋巴结清扫,是胃癌根治术的关键。随着国内外相关系列临床研究的证实,将D2根治术作为LAGC的标准术式已达成全球共识。合理的淋巴结清扫,对改善患者的预后和减少手术的并发症,具有重要的临床意义。而选择性地进行扩大淋巴结清扫,也可使部分患者获益。但是,对于合理的D2淋巴结清扫范围,目前仍然存在争议。为了指导我国LAGC淋巴结清扫的规范实施,中国抗癌协会胃癌专业委员会组织国内胃癌治疗领域的专家,对LAGC淋巴结清扫的关键内容进行多次讨论,并对争议问题进行投票,共同制定了《局部进展期胃癌规范化淋巴结清扫范围中国专家共识(2022版)》。希望本共识能为广大临床医师提供参考,进而提高我国LAGC的诊疗水平。

Currently,surgery-based comprehensive therapy plays an important role in the treatment of local advanced gastric cancer(LAGC),and standard lymph node dissection is a mainstay of gastric surgery.Radical gastrectomy with D2 lymph node dissection is widely accepted based on the international publications of randomized clinical trials,but the extent of lymph node dissection is controversial.An adequate lymph node dissection may improve prognosis and reduce complications,and D2+lymphadenectomy may improve surgical outcomes in some selected patients.To improve the efficacy of LAGC therapies,the Gastric Cancer Association,China Anti Cancer Association took the lead and organized experts to discuss and vote,and finally formulated this expert consensus.It is hoped that this consensus can provide reference for clinicians and further improve the diagnosis and treatment level of LAGC in China.
