摘要:

目的 探讨胸腺嘧啶核苷激酶1(TK1)在肝细胞肝癌(HCC)辅助诊断及预后评估中的临床价值。方法 选取HCC初诊患者123例(HCC组)、其他肝脏疾病患者83例(疾病对照组)、健康体检者97名(正常对照组),检测所有对象血清TK1、甲胎蛋白(AFP)及糖类抗原19-9(CA19-9)水平。收集HCC患者的一般资料、临床病理特征。检测HCC患者术后1周、1个月、3个月、6个月的血清TK1水平,同时随访12个月,观察复发情况。采用受试者工作特征(ROC)曲线评价各项指标辅助诊断HCC的价值。采用Kaplan-Meier生存曲线评估HCC患者的预后,采用多因素Cox比例回归分析评估HCC复发的风险因素。结果 HCC组、疾病对照组及正常对照组之间血清TK1水平依次降低,各组间差异均有统计学意义(P<0.001)。HCC患者中TNM分期Ⅲ~Ⅳ期者血清TK1水平高于Ⅰ~Ⅱ期者(P<0.05),其他不同临床病理特征的HCC患者之间血清TK1水平差异均无统计学意义(P>0.05)。ROC曲线分析结果显示,血清TK1、AFP、CA19-9辅助诊断HCC的曲线下面积(AUC)分别为0.798、0.903、0.683。在联合检测的不同组合中,TK1+AFP组合的诊断效能最高,辅助诊断HCC的AUC为0.922。Kaplan-Meier生存曲线分析结果显示,术前高TK1水平(TK1≥2.00 pmol/L)者无进展生存期(PFS)短于低TK1水平(TK1<2.00 pmol/L)者(P<0.001)。多因素Cox比例回归分析结果显示,AFP和TK1是预测HCC复发的独立风险因素[风险比(HR)分别为1.000、1.016,95%可信区间(CI)分别为1.000~1.001、1.010~1.023]。血清TK1动态监测结果显示,复发组术后6个月血清TK1水平显著升高(P<0.05),无进展组术后各时间点血清TK1水平差异均无统计学意义(P>0.05)。结论 血清TK1在HCC的辅助诊断及预后评估中均有一定的价值,且是预测HCC复发的独立风险因素。

Abstract:

Objective To investigate the auxiliary diagnostic and clinical prognostic evaluation value of thymidine kinase 1(TK1)determination in hepatocellular cancer(HCC). Methods A total of 123 newly diagnosed HCC patients(HCC group),83 other liver disease patients(disease control group) and 97 healthy subjects(healthy control group) were enrolled. Serum TK1,alpha-fetoprotein(AFP) and carbohydrate antigen 19-9(CA19-9)were determined. The general data and clinicopathologic characteristics of HCC patients were collected. HCC patients' serum TK1 levels were determined in 1 week,1 month,3 months and 6 months after operation. HCC recurrence was evaluated and followed up for 12 months. Receiver operating characteristic(ROC) curve analysis was used to evaluate the diagnostic value of different tumor markers in HCC. Kaplan-Meier survival curve and multivariate Cox proportional regression analysis were used to assess the prognosis of HCC patients and the risk factors for HCC recurrence. Results The levels of serum TK1 among HCC,disease control and healthy control groups decreased sequentially(P<0.001). Serum TK1 levels of HCC patients in TNM stage Ⅲ to Ⅳ were higher than those in stage Ⅰ to Ⅱ(P<0.05),while there was no statistical significance in serum TK1 levels between HCC patients with different clinicopathologic characteristics(P>0.05). ROC curve analysis showed that the areas under curves(AUC) of TK1,AFP and CA19-9 for the diagnosis of HCC were 0.798,0.903 and 0.683,respectively. The TK1+AFP combined determination had the highest diagnostic efficiency,and the AUC for diagnosing HCC auxiliarily was 0.922. Kaplan-Meier survival curve analysis showed that the progression-free survival(PFS) of patients with high preoperative serum TK1 level(TK1≥2.00 pmol/L) was shorter than that of patients with low serum TK1 level(TK1<2.00 pmol/L)(P<0.001). Multivariate Cox proportional regression analysis showed that AFP and TK1 were independent risk factors for predicting HCC recurrence [hazard ratios(HR) were 1.000 and 1.016,and 95% confidence intervals(CI) were 1.000-1.001 and 1.010-1.023,respectively]. Serum TK1 dynamic monitoring results showed that serum TK1 levels in recurrence group were increased 6 months after operation(P<0.05),and there was no statistical significance in serum TK1 levels in the progression-free group at various time points after operation(P>0.05). Conclusions Serum TK1 has a certain value in the auxiliary diagnosis and clinical prognostic evaluation of HCC,and it is an independent risk factor for predicting the recurrence of HCC.
