摘要:

目的 基于aMAP评分联合RAR及PIV构建并验证慢性肝病患者肝细胞癌(HCC)发生风险的预测模型。方法 143例慢性肝病患者按照是否发生HCC分为HCC组32例及非HCC组111例,比较2组一般临床资料、aMAP评分及外周血指标水平。采用多因素Logistic回归分析住院慢性肝病患者发生HCC的影响因素,构建并验证列线图风险预测模型。结果 与非HCC组比较,HCC组年龄大、男性比例高,总胆红素(TBIL)、红细胞分布宽度(RDW)、中性粒细胞计数(NEU)、单核细胞计数(MON)、aMAP评分、RDW与ALB比值(RAR)、泛免疫炎症值(PIV)水平高,白蛋白(ALB)、淋巴细胞计数(LYM)水平低(P<0.05)。多因素Logistic回归分析显示,较高aMAP评分、RAR、PIV是住院慢性肝病患者HCC风险的独立危险因素(P<0.05);据此构建的列线图风险预测模型受试者工作特征(ROC)曲线的曲线下面积(AUC)为0.823(95%CI:0.747~0.899),校准曲线显示预测值与实际观测值基本一致,Brier得分为0.125,决策曲线显示该模型具有明显的正向效益,Bootstrap法对预测模型进行内部验证的AUC为0.823(95%CI:0.820~0.825),提示模型具有良好的区分度。结论 aMAP评分联合RAR及PIV构建的慢性肝病患者发生HCC的列线图风险预测模型预测性能良好,有助于指导个体化治疗及随访。

Abstract:

Objective To construt and validate a risk prediction model for hepatocellular carcinoma (HCC) in patients with chronic liver disease based on age-male -ALBI-platelets (aMAP) score combined with RAR and PIV.Methods A total of 143 patients with chronic liver disease were divided into the HCC group (32 cases) and the non-HCC group (111 cases) according to whether HCC occurred. General clinical data, aMAP score and peripheral blood indicator level were compared between two groups. Multivariate Logistic regression was used to analyze influencing factors of HCC in inpatients with chronic liver disease. A nomogram risk prediction model was constructed and validated.Results Compared with the non-HCC group, there were higher age, higher proportion of males, higher levels of total bilirubin (TBIL), red blood cell distribution width (RDW), neutrophil count (NEU) and monocyte count (MON), lower levels of albumin (ALB) and lymphocyte count (LYM), higher levels of aMAP score, RDW to ALB (RAR) and pan-immune inflammation value (PIV) in the HCC group (P<0.05). Multivariate Logistic regression showed that higher levels of aMAP score, RAR and PIV were independent risk factors for HCC in inpatients with chronic liver disease (P<0.05). The area under receiver operator characteristic (ROC) curve (AUC) of the nomogram risk prediction model constructed based on above factors was 0.823 (95%CI: 0.747-0.899). The calibration curve showed that the predicted value was basically consistent with the actual observed value, and the Brier score was 0.125. The decision curve showed that the model had a clear positive net benefit. The AUC of internal validation of the prediction model by Bootstrap method was 0.823 (95%CI: 0.820-0.825), indicating that the model had a good degree of differentiation.Conclusion The nomogram risk prediction model based on aMAP score, RAR and PIV showed a good predictive performance of HCC in patients with chronic liver disease, which could benefits the individualized treatment and follow-up.
