摘    要:目的 探讨肺癌纵隔淋巴结不同切除方式对非小细胞肺癌患者围手术期免疫功能的影响.方法 连续收集2009年3月至2012年3月接受手术治疗的415例非小细胞肺癌患者临床资料,其中系统性淋巴结清扫术(SLND)组216例,淋巴结采样术(LNS)组199例.检查所有患者术前、术后3d及术后7d外周血淋巴细胞计数(LC)及淋巴细胞中CD4+T淋巴细胞、CD8+T淋巴细胞、自然杀伤(NK)细胞比例.对两组患者上述指标进行比较.结果 SLND组术后各时点全血中淋巴细胞、CD8+T淋巴细胞、NK细胞比例均低于LNS组,差异有统计学意义[术后3d:淋巴细胞(0.95±0.57)×10^9/L比(1.10±0.65)×10^9/L,CD8+T淋巴细胞(19.53±6.48)%比(20.93±6.70)%,NK细胞(17.36±6.06)%比(18.57 ±5.97)%,均P<0.05;术后7d:淋巴细胞(0.86±0.53)×10^9/L比(1.00±0.60)×10^9/L,CD8+T淋巴细胞(17.27±5.64)%比(18.40±5.26)%,NK细胞(13.11 ±4.84)%比(14.20±5.30)%,均P< 0.05];术后3d时LND组CD4+T淋巴细胞低于SLNS组,差异有统计学意义[(29.59±6.53)%比(31.19±6.32)%,P<0.05],术后7d时两组差异无统计学意义[(36.64±6.65)%比(37.20±6.83)%,P>0.05].结论 与SLND相比较,LNS可以减轻患者术后免疫功能的抑制.

Abstract:Objective To explore the influence of different method of mediastinal lymph node excision on the immune function of non-small cell lung cancer patients.Metbods Clinical data was collected continuously from 415 cases of inhospital patients with non-small cell lung cancer from March 2009 to March 2012,who were divided into system lymph node dissection group (SLND,216 cases) and lymph node sampling group (LNS,199 cases).The total lymphocytes,NK cells,CD4+ T cells and CD8+ T cells in blood samples taken preoperatively and at 3rd and 7th day postoperation were analyzed.Results Total lymphocytes,NK cells and CD8+ T cells were reduced significantly in the SLND group compared with those in LNS group at 3rd day and 7th day postoperation (3rd day:LC (0.95±0.57) ×10^9/L vs (1.10±0.65) ×10^9/L,CD8+ T cells (19.53± 6.48) % vs (20.93±6.70) %,NK (17.36±6.06) % vs (18.57±5.97) %,P 〈 0.05; 7th day:LC (0.86±0.53) ×10^9/L vs (1.00±0.60) ×10^9/L,CD8+ T cells (17.27±5.64) % vs (18.40±5.26) %,NK (13.11±4.84) % vs (14.20± 5.30) %; P 〈 0.05).CD4+ T cells in the SLND group were reduced significantly at 3rd day postoperation compared with LNS group ((29.59±6.53) % vs (31.19±6.32) %,P 〈 0.05).Conclusion LNS can reduce immunosuppression compared with SLND for postoperative patients.
