胃癌的患病率及病死率在我国均居恶性肿瘤前2位,在世界范围也位居前3位。外科治疗被认为是根治胃癌的有效方法,D2清扫术作为进展期胃癌的标准术式国内外已趋于一致,而规范化淋巴结清扫能明显提高5年生存率,改善预后。淋巴结清扫是外科手术的重点和难点。近年来,胃癌淋巴结清扫也越来越受到重视,对其分期要求也更为细致、精确。因此,美国癌症联合委员会的第7版《AJCC癌症分期手册》以及日本胃癌学会的第3版《胃癌治疗指南》均对胃癌分期有了较大的更
The prevalence and mortality of gastric cancer are the top two malignant tumors in our country and the top three in the world.
