摘要: 目的 探讨老年非小细胞肺癌(NSCLC)患者经表皮生长因子受体酪氨酸激酶抑制剂(EGFR-TKI)治疗前衰弱状态对预后的影响,并基于此构建预后预测模型。 方法 回顾性分析2020年1月至2023年12月邯郸市中心医院221例接受EGFR-TKI治疗的老年NSCLC患者临床资料。治疗前采用简化5因素修正衰弱指数(mFI-5)评估患者衰弱状态,以总生存期(OS)为随访终点,随访截至2025年8月1日。 结果 共53例(24.0%)患者治疗前存在衰弱。随访期间22例(10.0%)死亡。多因素logistic回归分析显示,胸膜侵犯、淋巴侵犯、高龄、肿瘤大小、吸烟指数是患者衰弱的独立相关因素(P<0.05);多因素Cox回归结果显示,淋巴侵犯、鳞状细胞癌、吸烟指数、衰弱状态是患者预后不良的独立危险因素(P<0.05)。衰弱患者中位生存期为2.71年,显著低于非衰弱患者(中位生存期未达到,Log rank P<0.001)。基于上述4项预后危险因素构建列线图模型,经Bootstrap法内部验证(重复抽样1000次),模型的一致性指数(C-index)为0.79,ROC曲线分析显示其预测预后不良的AUC为0.81(95%CI:0.69~0.92)。 结论 基于mFI-5评估的衰弱状态与接受EGFR-TKI治疗的老年NSCLC患者OS降低相关。本研究初步构建的包含衰弱状态、淋巴侵犯、鳞状细胞癌、吸烟指数的列线图模型,展现出一定的预后预测潜力。

Abstract: Objective To investigate the impact of frailty before treatment on the prognosis of elderly patients with non-small cell lung cancer (NSCLC) receiving epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) therapy, and to construct a prognostic prediction model. Methods A retrospective analysis was performed on clinical data of 221 elderly NSCLC patients treated with EGFR-TKI in Handan Central hospital from January 2020 to December 2023. The simplified 5-factor modified frailty index (mFI-5) was used to assess frailty status before treatment. Overall survival (OS) was set as the follow-up endpoint, with follow-up ending on August 1, 2025. Results Among the patients, 53 cases (24.0%) had frailty before treatment and 22 cases (10.0%) died during follow-up. Logistic regression analysis indicated that pleural invasion, lymphatic invasion, advanced age, tumor size and smoking index were independently associated with frailty (P<0.05). Cox regression analysis revealed that lymphatic invasion, squamous cell carcinoma, smoking index and frailty status were independent risk factors for poor prognosis (P<0.05). The median survival time of frail patients was 2.71 years, which was significantly shorter than that of non-frail patients (Log rank P<0.001). A nomogram model was constructed based on the above four prognostic risk factors. Internal validation via the Bootstrap method (1000 resamplings) showed that the concordance index (C-index) of the model was 0.79. Receiver operating characteristic (ROC) curve analysis revealed that the area under the curve (AUC) of the model for predicting poor prognosis was 0.81(95%CI: 0.69-0.92). Conclusions Frailty status assessed by mFI-5 is associated with decreased OS in elderly NSCLC patients treated with EGFR-TKI. The nomogram model incorporating frailty status, lymphatic invasion, squamous cell carcinoma and smoking index has high predictive value for poor prognosis in these patients.
