- W4224251906 abstract "Objective: To explore the value of enhanced magnetic resonance imaging nomogram model in the prediction of dual-phenotype hepatocellular carcinoma(DPHCC). Methods: Data of 116 patients of hepatocellular carcinoma (HCC) confirmed by postoperative pathology, who underwent preoperative enhanced MRI between January 2016 and March 2021 in the First Affiliated Hospital of Soochow University were retrospectively evaluated, of these, there are 87 males and 28 females, aged 30-79 (59±10) years, including 31 patients with DPHCC and 85 patients with non-DPHCC. The patients were randomly divided into training set(51 cases of non-DPHCC,19 cases of DPHCC)and validation set(34 cases of non-DPHCC, 12 cases of DPHCC) in a ratio of 6∶4, according to random number table,clinical and imaging characteristics of the two groups were compared. The statistically significant parameters were included in multivariate logistic regression to identify the independent predictors and for the establishment of the nomogram model. The receiver operating characteristic curves were used to evaluate the prediction ability of the models, the corrected curve was used to validate the model. Results: In the training group, the proportions of rim arterial phase hyperenhancement in the DPHCC was significantly higher than that of the non-DPHCC [47.4%(9/19)vs 7.8%(4/51),P<0.001]. Rim arterial phase hyper-enhancement and enhanced capsule were significant predictors for DPHCC[OR=10.17(1.70-60.80),0.17(0.03-0.93),all P<0.05]. In the training group, the area under curve (AUC), sensitivity and specificity of the nomogram were 0.888 (95%CI: 0.806-0.969), 78.9% and 86.3%. In the validation group, the above three indicators were 0.811(95%CI: 0.655-0.968), 75.0% and 82.4%. Conclusion: Enhanced MRI nomogram model has certain value in prediction of DPHCC, with high sensitivity and specificity.目的： 探讨增强 MRI列线图模型在预测双表型肝细胞癌（DPHCC）中的应用价值。 方法： 回顾性分析2016年1月至2021年3月于苏州大学附属第一医院行增强MRI检查并经手术病理证实为肝细胞癌（HCC）的116例患者资料，男87例，女29例，年龄30~79（59±10）岁，其中DPHCC 31例，非双表型肝细胞癌（非DPHCC）85例，并按照6∶4的比例，采用随机数字表法分为训练组（51例非DPHCC，19例DPHCC）及验证组（34例非DPHCC，12例DPHCC），比较两组患者的临床及影像学特征的差异。然后将差异有统计学意义的特征纳入多因素logistic回归，获得独立预测指标并建立列线图模型，采用受试者工作特征曲线评估模型的预测能力，采用校准曲线对模型进行验证。 结果： 在训练组中，DPHCC中环形动脉期高强化的患者占比高于非DPHCC［47.4%（9/19）比 7.8%（4/51），P<0.001］。环形动脉期高强化、强化的包膜是DPHCC的预测因素［OR值（95%CI）分别是10.17（1.70~60.80）、0.17（0.03~0.93），均P<0.05］。在训练组中，列线图的曲线下面积（AUC）、灵敏度、特异度分别为0.888（95%CI：0.806~0.969）、78.9%、86.3%；在验证组中，以上3个指标分别为0.811（95%CI：0.655~0.968）、75.0%、82.4%。 结论： 增强MRI列线图模型对DPHCC具有一定的预测效能，灵敏度、特异度高。." @default.
