Th17细胞相关因子在早晚期肺癌患者中的表达差异及临床意义

目的对比Th17细胞相关因子在不同分期非小细胞肺癌(NSCLC)患者中的表达差异，并分析临床意义，为肺癌免疫研究提供参考。 方法选择我院2016年2月至2019年2月收治的41例NSCLC患者为研究组，19例在我院接受常规体检的健康者作为对照组，全部受检者均接受Th17细胞及相关因子表达检测，包括白细胞介素-17(IL-17)、白细胞介素-21(IL-21)，对比对照组与研究组Th17细胞相关因子表达情况，对比研究组不同性别、年龄Th17细胞相关因子表达；根据研究组病理分期，对比不同病理分期NSCLC患者Th17细胞相关因子表达，经Pearson相关性分析Th17细胞相关因子与NSCLC病理分期的相关性。 结果研究组Th17细胞比例、IL-17水平、IL-21表达高于对照组，差异有统计学意义(P<0.05)；不同性别、不同年龄间NSCLC患者Th17细胞及其相关因子水平比较，差异均无统计学意义(P>0.05)；随着肿瘤分期增加，NSCLC患者外周血Th17细胞比例及IL-17、IL-21表达均呈升高趋势，各分期间两两比较差异均有统计学意义(P<0.05)；Th17细胞比例、IL-17、IL-21表达与NSCLC患者肿瘤分期呈正相关(r＝0.620、0.631、0.583，P均<0.001)。 结论NSCLC患者外周血中Th17细胞呈高表达，且随病情的进展不断升高，检测NSCLC患者外周血Th17细胞及其相关因子水平，对病情的判断及了解患者机体免疫功能有重要的临床意义。

Expression difference and clinical significance of Th17 cell-related factors in patients with early stage and advanced stage of lung cancer

ObjectiveTo compare the expression difference of Th17 cell-related factors in the patients with different stages of non-small cell lung cancer (NSCLC) in order to analyze its clinical significance and therefore provide references for the future study of lung cancer immunity. MethodsA total of 41 patients with NSCLC in our hospital from February 2016 to February 2019 were included in the experimental group, and 19 healthy people through the routine physical examination were taken as the healthy control group. All the selected cases received Th17 cell-related factor detection, including interleukin-17 (IL-17) and IL-21. The expression levels of Th17 cell-related factors between the healthy control group and the experimental group were compared, and the expression levels of Th17 cell-related factors of the patients with different genders and ages in the experimental group were compared respectively. The expression levels of Th17 cell-related factors in the patients with different pathological stages of NSCLC were compared, too. The correlation between the Th17 cell-related factors and the pathological stages of NSCLC was analyzed by Pearson correlation. ResultsThe ratio of Th17 cells and the expression levels of IL-17 and IL-21 in the experimental group were higher than those of the healthy control group (P<0.05). There was no statistical difference in the Th17 cells and the related factors among the NSCLC patients with different genders and ages (P>0.05). With the increase of tumor stages, the ratio of Th17 cells in the peripheral blood and the expression levels of IL-17 and IL-21 in the patients with NSCLC showed an increasing trend, and the difference between the two groups was statistically significant (P<0.05). The ratio of Th17 cells and the expression levels of IL-17 and IL-21 had positive correlation with the tumor stages of the NSCLC patients (r=0.620, 0.631 and 0.583, respectively, P<0.001). ConclusionThe expression levels of Th17 cells in the peripheral blood of the patients with NSCLC are higher compared with those of the healthy persons and they increase with the progress of the disease. Detecting the levels of Th17 cells and the related factors in the peripheral blood of the patients with NSCLC has an important clinical significance in the judgment of the disease and the understanding of the immune function.
