摘要:

目的 探讨血清细胞分裂周期蛋白42 (CDC42)水平与甲胎蛋白(AFP)阴性肝细胞肝癌(HCC)患者临床病理特征和预后的关系。方法 选取2015年1月—2020年12月海安市人民医院AFP阴性HCC患者120例(AFP阴性HCC组)和健康体检者40名(正常对照组)。收集所有研究对象的临床资料,并检测血清CDC42水平。采用Kaplan-Meier生存曲线分析AFP阴性HCC患者的生存情况。采用Cox风险比例回归分析评估AFP阴性HCC患者死亡的影响因素。采用受试者工作特征(ROC)曲线评价CDC42判断AFP阴性HCC患者死亡的效能。结果 AFP阴性HCC组血清CDC42水平显著高于正常对照组(P<0.001)。不同Stage分期、T分期、N分期、M分期的AFP阴性HCC患者之间血清CDC42水平差异均有统计学意义(P<0.001)。低CDC42组总生存率高于高CDC42组(Log-rankχ2=8.71,P<0.001)。CDC42和Stage分期是AFP阴性HCC患者死亡的独立危险因素[风险比(HR)值分别为1.274、3.666,95%可信区间(CI)分别为1.12~1.47、1.70~7.92]。CDC42判断AFP阴性HCC患者死亡的曲线下面积为0.723,最佳临界值为1.092 ng·mL-1,敏感性为75.0%,特异性为68.3%。结论 CDC42与HCC的临床病理特征密切相关,或可作为AFP阴性HCC患者的预后评估指标。

Abstract:

Objective To investigate the relationship between serum cell division cyclin 42(CDC42)and clinicopathological characteristics and prognosis of alpha-fetoprotein (AFP)-negative hepatocellular carcinoma (HCC) patients. Methods A total of 120 AFP-negative HCC patients (AFP-HCC group) and 40 healthy subjects (healthy control group) were enrolled from Hai'an People's Hospital from January 2015 to December 2020. The clinical data were collected,and serum CDC42 levels were determined. Kaplan-Meier survival curve was used to analyze the survival of AFP-negative HCC patients,and Cox risk proportional regression analysis was used to evaluate the influencing factors of death in AFP-negative HCC patients. Receiver operating characteristic(ROC) curve was used to evaluate the efficacy of CDC42 in determining death in AFP-negative HCC patients. Results The serum CDC42 level in AFP-HCC group was higher than that in healthy control group(P<0.001). There was statistical significance in serum CDC42 levels among AFP-negative HCC patients at different stages,T stages,N stages and M stages(P<0.001). The overall survival rate of low CDC42 group was higher than that of high CDC42 group(Log-rank χ2=8.71,P<0.001). CDC42 and Stage stage were independent risk factors for prognosis(death)in AFP-negative HCC patients [hazard ratios(HR)were 1.274 and 3.666,95% confidence intervals(CI)were 1.12-1.47 and 1.70-7.92]. The area under curve of CDC42 to determine the death of AFP-negative HCC patients was 0.723,the optimal cut-off value was 1.092 ng·mL-1,the sensitivity was 75.0%,and the specificity was 68.3%. Conclusions CDC42 is related to the clinicopathological characteristics of HCC,and may be used as a prognostic indicator for AFP-negative HCC patients.
