摘要:

目的 研究非小细胞肺癌(NSCLC)患者血清miR-19b、miR-744-5p水平,分析其在NSCLC诊断中的临床价值。方法 选择吉林省肿瘤医院2019年8月至2022年8月收治的NSCLC患者226例(NSCLC组)和健康体检者100例(对照组)为研究对象。采用实时荧光定量PCR测定并比较NSCLC组和对照组血清miR-19b、miR-744-5p水平,分析二指标与NSCLC患者不同临床病理特征的关系,采用受试者操作特征曲线分析miR-19b、miR-744-5p和二者联合检测诊断NSCLC的临床价值。结果 与对照组比较,NSCLC组血清miR-19b水平显著升高(3.86±1.25比1.06±0.41,t=21.87,P<0.001),miR-744-5p水平显著降低(1.80±0.48比5.75±1.69,t=32.36,P<0.001)。病理类型为腺癌、肿瘤最大径≥3 cm、中低分化、Ⅲ~Ⅳ期、伴有淋巴结转移的NSCLC患者血清miR-19b水平分别高于鳞状细胞癌(t=5.94,P<0.001)、肿瘤最大径<3 cm(t=2.65,P=0.009)、高分化(t=4.33,P<0.001)、Ⅰ~Ⅱ期(t=12.32,P<0.001)、不伴有淋巴结转移患者(t=8.13,P<0.001),而miR-744-5p水平分别低于鳞状细胞癌(t=8.27,P<0.001)、肿瘤最大径<3 cm(t=5.34,P<0.001)、高分化(t=6.95,P<0.001)、Ⅰ~Ⅱ期(t=11.40,P<0.001)、不伴有淋巴结转移患者(t=10.36,P<0.001)。血清miR-19b联合miR-744-5p检测诊断NSCLC的曲线下面积(AUC)为0.914(95%CI为0.841~0.959),敏感性和特异性分别为90.9%和84.0%,AUC显著大于miR-19b(AUC为0.824,95%CI为0.770~0.869)、miR-744-5p(AUC为0.783,95%CI为0.709~0.838)单一指标检测(Z=2.28,P=0.021;Z=2.36,P=0.017)。结论 NSCLC患者血清miR-19b水平升高、miR-744-5p水平降低,血清miR-19b、miR-744-5p联合检测在NSCLC诊断中具有较高的临床价值。

Abstract:

Objective To investigate the serum levels of miR-19b and miR-744-5p in patients with non-small cell lung cancer (NSCLC),and to analyze the clinical value of miR-19b and miR-744-5p in the diagnosis of NSCLC. Methods A total of 226 NSCLC patients (NSCLC group)and 100 healthy people (control group)admitted to Jilin Cancer Hospital from August 2019 to August 2022 were selected as research objects. Quantitative real-time PCR was used to measure and compare the serum levels of miR-19b and miR-744-5p between the NSCLC group and the control group,and the relationships between the two indicators and different clinical and pathological characteristics of NSCLC patients were analyzed. The receiver operating characteristic curve was used to analyze the clinical value of miR-19b,miR-744-5p and their joint detection in the diagnosis of NSCLC. Results Compared with the control group,the serum miR-19b level (3.86±1.25 vs. 1.06±0.41)in the NSCLC group significantly increased (t=21.87,P<0.001),while the miR-744-5p level (1.80±0.48 vs. 5.75±1.69)significantly decreased (t=32.36,P<0.001). The serum miR-19b levels in NSCLC patients with pathological types of adenocarcinoma,maximum tumor diameter ≥3 cm,medium to low differentiation,stage Ⅲ-Ⅳ,and with lymph node metastasis were higher than those in squamous cell carcinoma (t=5.94,P<0.001),maximum tumor diameter <3 cm (t=2.65,P=0.009),well differentiation (t=4.33,P<0.001),stageⅠ-Ⅱ (t=12.32,P<0.001),patients without lymph node metastasis (t=8.13,P<0.001),while miR-744-5p levels were lower than those in squamous cell carcinoma (t=8.27,P<0.001),tumor maximum diameter <3 cm (t=5.34,P<0.001),well differentiation (t=6.95,P<0.001),stageⅠ-Ⅱ (t=11.40,P<0.001),patients without lymph node metastasis (t=10.36,P<0.001). The area under the curve (AUC)of serum miR-19b combined with miR-744-5p in the diagnosis of NSCLC was 0.914 (95%CI:0.841-0.959),with sensitivity and specificity of 90.9% and 84.0%,respectively. AUC was significantly than that of the single indicator detection of miR-19b (AUC=0.824,95%CI:0.770-0.869)and miR-744-5p (AUC=0.783,95%CI:0.709-0.838)(Z=2.28,P=0.021; Z=2.36,P=0.017). Conclusion Serum miR-19b level of NSCLC patients is increased,miR-744-5p levels is decreased,and joint detection of serum miR-19b and miR-744-5p has high clinical value in the diagnosis of NSCLC.
