摘要: 目的:探讨血清谷胱甘肽过氧化物酶(GSH-PX)活性与晚期非小细胞肺癌(NSCLC)患者临床病理指标、放化疗联合治疗的疗效及预后的相关性。方法:收集174例2018年1—12月于河北工程大学附属医院肿瘤科初次确诊、未经抗癌治疗的晚期NSCLC患者作为研究对象,以80例健康体检者为对照,患者于放化疗联合治疗前采集外周血,分离血清。采用基因表达谱数据动态分析(GEPIA)数据库分析GSH-PX的编码基因GPX3在不同肿瘤组织中的表达情况;5',5-二硫硝基苯甲酸(DTNB)法检测GSH-PX活性,比较放化疗联合治疗前晚期NSCLC患者和对照组血清GSH-PX活性,并分析血清GSH-PX活性与晚期NSCLC临床病理指标、放化疗联合治疗疗效及预后的相关性。结果:GEPIA数据库分析显示33类肿瘤组织中,21类肿瘤组织的GPX3 mRNA表达低于正常组织,其中包括肺鳞癌和肺腺癌(P<0.05);DTNB法检测结果显示晚期NSCLC患者血清GSH-PX活性显著低于健康对照组(P<0.05);与年龄、性别、病理类型无明显相关(均为P>0.05),与吸烟史和肿瘤大小呈负相关(r=-0.165、-0.267,均为P<0.05),与卡氏(KPS)评分和病理分级呈正相关(r=0.295、0.228,均为P<0.05);治疗有效患者和无效患者血清GSH-PX活性的差异无统计学意义(P>0.05),但GSH-PX高活性组患者总生存期显著高于低活性组(P<0.05),且呈正相关(r=0.238,P=0.000)。结论:晚期NSCLC患者血清GSH-PX活性降低,与患者吸烟史、KPS评分、肿瘤大小、病理分级和总生存期显著相关。GSH-PX可能参与了NSCLC的发生发展,可作为评估预后的指标。

Abstract: OBJECTIVE: To investigate correlations between glutathione peroxidase (GSH-PX) in serum and clinicopathological indicators,curative effect of combined radio-with chemotherapy and prognosis of advanced non-small cell lung cancers (NSCLC). METHODS: In 2018,174 newly diagnosed advanced NSCLC patients (before anticancer therapy) from the Department of Oncology,Affiliated Hospital of Hebei University of Engineering and 80 healthy controls were recruited for our investigation. Expressions of GPX3 in different tumors were analyzed via the data of on-line. Activities of GSH-PX in serum from peripheral blood samples were detected via 5',5-dithio-bis-nitrobenzoic acid (DTNB). Activities of GSH-PX were compared between the advanced NSCLC and the control groups. In addition,relationships between activities of GSH-PX and clinicopathological indicators,curative effect of combined radio-with chemotherapy and prognosis of advanced non-small cell lung cancer were analyzed. RESULTS: Data from the gene expression profiling interactive analysis (GEPIA) show that expressions of GPX3 in 33 kinds of tumors (lung squamous cell carcinoma and lung adenocarcinoma) were significantly lower than that in the controls (P<0.05). Results from DTNB show that GSH-PX activities in serums of patients were significantly lower than that in the controls (P<0.05) and were irrelevant to the age,gender and pathological patterns of patients (P>0.05). However GSH-PX activities were negatively related to smoking histories and tumor sizes (r=-0.295、0.228,all P<0.05),and positively related to KPS scores and pathological grades (r=0.295、0.228,P all <0.05). There was no difference in GSH-PX activities between patients with effective and failed treatments (P>0.05). Overall survivals in the high activities group was higher than those in the low activities group (P<0.05),and they were positively related (r=0.238,P=0.000). CONCLUSION: GSH-PX activities in serum of patients with advanced NSCLC were significantly reduced,and the activities were related to smoking histories,KPS scores,tumor sizes,pathological grades and overall survivals. Therefore,GSH-PX activities were involved in the development and prognosis of NSCLC.
