摘要 目的探讨进展期胃癌(AGC)患者行合并腹主动脉旁淋巴结(PAL)清扫的胃癌扩大根治术(D3+PAL)前后细胞免疫功能的变化,并与D2手术后的细胞免疫功能进行对比分析。方法应用改良MTT法和T淋巴细胞亚群SAP法检测104例AGC患者和33例正常对照(对照组)外周血的NK细胞杀伤活性及T淋巴细胞亚群的变化。结果与对照组相比,2组AGC患者手术前NK细胞活性,CD3^+、CD4^+、CD4^+/CD8^+明显降低(CD8^+升高),术后D3+PAL组NK细胞活性,CD3^+、CD4^+、CD4^+/CD8^+比术前明显升高(P<0.05或0.01);与D2术后相比,D3+PAL术后NK细胞活性,CD3^+、CD4^+、CD4^+/CD8^+明显升高。结论手术前AGC患者细胞免疫功能明显降低,D3+PAL手术可明显改善AGC患者的细胞免疫功能,且比D2手术效果明显。
