摘要
目的探讨非小细胞肺癌(non-small cell lung cancer,NSCLC)组织中紧密连接蛋白10(claudin 10,CLDN10)和硫酸软骨素蛋白聚糖4(chondroitin sulfate proteoglycan 4,CSPG4)表达与临床病理特征和预后的关系。方法随机选取2017年1月~2018年4月于南京医科大学附属泰州市人民医院进行手术的136例NSCLC患者为研究对象,并根据随访结局(生存或死亡)分为生存组(n=63)和死亡组(n=69)。收集136例患者于手术过程中切除的癌组织及癌旁组织标本;实时荧光定量PCR(real-time fluorescence quantitative PCR,RT-qPCR)检测癌组织及癌旁组织CLDN10和CSPG4表达水平,并分别以NSCLC患者癌组织中CLDN10和CSPG4表达水平的平均数为界限,分为CLDN10高表达组(n=66),CLDN10低表达组(n=70)和CSPG4高表达组(n=71),CSPG4低表达组(n=65);采用多因素COX回归分析确定NSCLC患者预后的影响因素;采用Kaplan-Meier生存曲线分析NSCLC患者CLDN10和CSPG4表达水平与其预后的关系。结果NSCLC组织中CLDN10表达水平(0.96±0.25)低于癌旁组织(1.73±0.42),CSPG4表达水平(1.80±0.46)高于癌旁组织(1.04±0.27),差异有统计学意义(t=18.372,16.617,均P<0.05)。与生存组比较,死亡组低未分化占比、淋巴结转移占比及癌组织中CSPG4表达水平较高,CLDN10表达水平较低,差异具有统计学意义(t/χ^(2)=8.463,7.423,11.696,6.426,均P<0.05)。CLDN10高表达组五年存活率(58.46%)高于低表达组(37.31%),CSPG4低表达组患者五年存活率(55.56%)高于高表达组(40.58%),差异有统计学意义(χ^(2)=7.848,4.018,均P<0.05)。多因素COX分析结果显示,CLDN10低表达、CSPG4高表达、低分化程度、淋巴结转移是NSCLC患者预后的危险因素(HR=1.362,1.368,1.335,1.314,均P<0.05)。结论NSCLC患者癌组织中CLDN10表达水平较低,CSPG4水平较高,且与NSCLC发展和预后密切相关。
Objective To investigate the relationship between the expression of claudin 10(CLDN10)and chondroitin sulfate proteoglycan 4(CSPG4)of tissue and clinicopathologic characteristics and prognosis in non-small cell lung cancer(NSCLC).Methods A total of 136 NSCLC patients who underwent surgery in Taizhou People’s Hospital,Nanjing Medical University from January 2017 to April 2018 were randomly selected as the study subjects,and these subjects were grouped into survival group(n=63)and death group(n=69)based on follow-up outcomes(survival or death).Specimens of cancer tissue and adjacent tissues excised during surgery were collected from 136 patients.Real-time fluorescence quantitative PCR(RT-qPCR)was applied to detect the expression levels of CLDN10 and CSPG4 in cancer tissue and adjacent tissues.Based on the average expression levels of CLDN10 and CSPG4 in cancer tissues of NSCLC patients,they were grouped into CLDN10 high expression group(n=66),CLDN10 low expression group(n=70)and CSPG4 high expression group(n=71),CSPG4 low expression group(n=65).Multivariate COX regression analysis was used to determine the prognostic factors of NSCLC patients.Kaplan-Meier survival curve was applied to analyze the relationship between the expression levels of CLDN10 and CSPG4 in NSCLC patients and their prognosis.Results The expression level of CLDN10(0.96±0.25)in NSCLC tissues was lower than that in adjacent tissue(1.73±0.42),and the expression level of CSPG4 in NSCLC tissues(1.80±0.46)was higher than that in adjacent tissues(1.04±0.27),with statistical significance(t=18.372,16.617,all P<0.05).Compared with the survival group,the proportion of low undifferentiated,lymph node metastasis and CSPG4 expression of cancer tissues in the death group were higher,and the CLDN10 expression level of cancer tissues in the death group was lower,with statistical significance(t/χ^(2)=8.463,7.423,11.696,6.426,all P<0.05).The five-year survival rate of the high expression group of CLDN10(58.46%)was higher than that of the low expression group(37.31%),and the five-year survival rate of the low expression group of CSPG4(55.56%)was higher than that of the high expression group(40.58%),and the differences were statistically significant(χ^(2)=7.848,4.018,all P<0.05).Multivariate COX analysis results showed that low expression of CLDN10,high expression of CSPG4,low differentiation degree,and lymph node metastasis were all risk factors affecting the prognosis of NSCLC patients(HR=1.362,1.368,1.335,1.314,all P<0.05).Conclusion The expression level of CLDN10 was low and CSPG4 was high in cancer tissues of NSCLC patients,which was closely related to the development and prognosis of NSCLC.
