摘要: 目的 探讨长链非编码RNA(lncRNA)锌指结构反义转录本1(ZFAS1)在骨肉瘤患者癌组织中的表达及其对患者预后的影响。方法 选取2009年6月—2015年6月商丘市中医院住院接受手术治疗的骨肉瘤患者101例,收集所有患者的癌组织和癌旁组织(距肿瘤边缘>5 cm),采用实时荧光定量聚合酶链反应(RT-qPCR)检测ZFAS1表达。对所有患者随访5年,截止时间为2020年6月30日,记录患者生存时间。采用Kaplan-Meier生存曲线分析骨肉瘤患者的生存情况,采用Cox比例风险回归模型分析影响骨肉瘤患者预后的因素。结果 癌组织ZFAS1相对表达量为2.74±0.23,显著高于癌旁组织(1.01±0.09)(t=71.876,P<0.001)。ZFAS1相对表达量在不同Enneking分期、KPS评分、分化程度和是否远隔转移的骨肉瘤患者之间差异均有统计学意义(P<0.05)。根据癌组织中ZFAS1相对表达量的均值将骨肉瘤患者分为高表达组(47例)和低表达组(54例)。Kaplan-Meier生存曲线分析结果显示,低表达组生存时间为(46.24±2.55)个月,5年生存率为61.11%,均高于高表达组[(26.09±2.76)个月和21.28%](Log-rank χ2=22.059,P<0.001)。Cox比例风险回归分析结果显示,Enneking分期、分化程度、远隔转移和ZFAS1表达是影响患者预后的独立危险因素[风险比(HR)值分别为2.620、0.384、2.197、1.978,95%可信区间(CI)分别为1.203~5.706、0.186~0.791、1.131~4.270、1.034~3.784]。结论 ZFAS1表达量与骨肉瘤患者恶性进展病理指标和预后相关,是影响患者预后的独立危险因素。

Abstract: Objective To investigate the expression of long non-coding RNA (lncRNA)zine finger antisense 1(ZFAS1) in osteosarcoma tissues and its influence on patient prognosis. Methods A total of 101 patients with osteosarcoma who were hospitalized in Shangqiu Hospital of Traditional Chinese Medicine for surgical treatment were enrolled from June 2009 to June 2015. Osteosarcoma and adjacent tissues(>5 cm from tumors) were collected. The expressions of ZFAS1 were determined by real-time fluorescence quantitative polymerase chain reaction(RT-qPCR). All the patients were followed up for 5 years until June 30,2020. The survival time of the patients were recorded. Kaplan-Meier method was used for survival analysis,and Cox regression model was used for prognostic influencing factor analysis. Results The relative expression level of ZFAS1 in osteosarcoma tissues was 2.74±0.23,which was higher than 1.01±0.09 in adjacent tissues(t=71.876,P<0.001). The relative expression levels of ZFAS1 in osteosarcoma tissues of patients with different Enneking stages,KPS scores,degrees of differentiation and metastasis had statistical significance(P<0.05). Kaplan-Meier survival analysis results showed that the survival time of patients in low expression group was(46.24±2.55) months,and the 5-year survival rate was 61.11%,which were higher than those in high expression group,which were(26.09±2.76) months and 21.28%,respectively(Log-rank χ2=22.059,P<0.001). The results of Cox proportional hazard regression model showed that Enneking stage,the degree of differentiation,metastasis and ZFAS1 expression were independent risk factors affecting patients' prognosis [hazard ratios(HR)were 2.620,0.384,2.197 and 1.978,95% confidence intervals(CI)were 1.203-5.706,0.186-0.791,1.131-4.270 and 1.034-3.784]. Conclusions The expression of ZFAS1 in osteosarcoma tissues is related to the pathological indicators of malignant progression of patients and prognosis,which is an independent risk factor affecting the prognosis of patients.
