肝细胞癌术后预防性经肝动脉插管化疗栓塞术筛选模型构建

肝细胞癌术后预防性经肝动脉插管化疗栓塞术筛选模型构建摘要：

目的：本研究旨在构建一种可行的筛选模型，以评估肝细胞癌（HCC）患者行术后预防性经肝动脉插管化疗栓塞术的风险。

方法：本研究共纳入了2010年1月至2018年12月间接受手术治疗的187例HCC患者。根据是否出现术后并发症（主要为肝功能不全和手术切口感染）将患者分为两组。使用受试者工作特征（ROC）曲线分析筛选因素的预测价值，并使用多元逻辑回归模型计算每个因素的OR值。

结果：本研究共筛选出9个预测因素，包括高凝血指数（OR=2.68，95%CI=1.32-5.45）、肝硬化（OR=2.64，95%CI=1.15-6.05）、肝癌病程时间（OR=4.32，95%CI=2.06-9.07）、红细胞压积（OR=2.00，95%CI=1.06-3.79）、肿瘤大小（OR=3.04，95%CI=1.29-7.16）、胆管癌累及（OR=3.38，95%CI=1.40-8.18）、腹腔内转移（OR=3.20，95%CI=1.59-6.44）、肝内卫星结节（OR=2.98，95%CI=1.20-7.36）和血红蛋白（OR=1.96，95%CI=1.25-3.08）。多元逻辑回归模型的面积下ROC曲线（AUC）为0.82（95%CI=0.76-0.87），该模型显示了较好的判别力度。

结论：本研究构建的筛选模型能够准确评估HCC患者接受术后预防性经肝动脉插管化疗栓塞术的风险，帮助临床医生更好地评估治疗策略，提高预后。
