Keyword:  胃肿瘤生物学行为手术方式;
Abstract: 目的:探讨胃癌的生物学行为特点对术式选择的价值.方法:1990年1月~2000年1月,首次行胃癌切除术病人224例,其中早期胃癌26例,进展期胃癌198例.随访率91.5%.全组均行次全或全胃切除加R1~3淋巴结清扫术.结果:①生存率比较:早期胃癌R1与R2 ,P>0.05.进展期胃癌R1与R2,P<0.01;R1与R3 ,P<0.01;R2与R3,P>0.05.②病灶浸润深度与淋巴结转移程度呈正相关,两者相辅相成提示病期预后.③肿瘤大小与生存率无统计学意义.④早期胃癌Ⅲ型生长、进展期胃癌浸润型生长预后最差.结论:胃癌的生物学行为对手术具有指导意义.早期胃癌行次全胃切加R1、选择性R2淋巴结清扫为宜;进展期胃癌宜行距肿瘤5 cm以上的次全或近全胃切加R2、选择性R3淋巴结清扫为宜.
