目的

构建高海拔地区肝细胞癌(hepatocellular carcinoma, HCC)患者接受肝动脉化疗栓塞(transarterial chemoembolization, TACE)联合靶免治疗后短期疗效的预测模型,为临床疗效评估提供量化工具。

方法

回顾性收集2018年10月至2024年10月于西藏自治区人民医院确诊为HCC且接受TACE治疗的患者资料,且收集患者均为世居高原人群(海拔≥3 600 m),最终纳入101例符合标准的患者。收集临床及影像学资料,通过单因素与多因素Logistic回归分析确定独立预测因素,并建立列线图模型。模型内部验证通过Bootstrap法(1 000次重复抽样)完成,采用ROC曲线、校正AUC、校准曲线以及临床决策曲线进行评估。

结果

肿瘤最大径(OR=1.598,95% CI: 1.265-2.017;P<0.05)、肿瘤无假包膜(OR=12.588,95% CI: 2.356-67.238;P<0.05)及最小表观扩散系数(OR=0.333,95% CI: 0.194-0.569;P<0.05)是影响治疗短期疗效的独立因素。经Bootstrap内部验证后,模型校正AUC为0.9532(95% CI: 0.919-0.993),并据此绘制可视化的列线图。

结论

该模型可为高海拔HCC患者疗效评估与个体化治疗提供量化工具。

Objective

This study sought to construct a predictive model for the short-term efficacy of transarterial chemoembolization (TACE) combined with targeted-immunotherapy in hepatocellular carcinoma (HCC) patients residing in high-altitude regions, offering a reliable quantifiable tool for clinical efficacy assessment.

Methods

A total of 101 eligible HCC patients were retrospectively included. Clinical and imaging data were collected, and independent predictive factors were identified via univariate and multivariate logistic regression analyses. A nomogram model was established, with internal validation performed using 1 000 bootstrap resamplings. Model performance was evaluated by receiver operating characteristic (ROC) curve, calibrated area under the curve (AUC), calibration curves, and decision curve analysis.

Results

Maximum tumor diameter (OR=1.598, 95% CI: 1.265-2.017, P<0.05), lack of tumor pseudocapsule (OR=12.588, 95% CI: 2.356-67.238, P<0.05), and lower minimum apparent diffusion coefficient (ADCmin, OR=0.333,95% CI: 0.194-0.569, P<0.05) were identified as independent predictors of short-term treatment response. After bootstrap validation, the model's calibrated AUC reached 0.953 (95% CI: 0.919-0.993), and a visualized nomogram was generated accordingly.

Conclusion

This predictive model serves as a reliable quantifiable tool for efficacy evaluation and personalized treatment decision-making in HCC patients from high-altitude regions.
