摘要

目的 探讨非小细胞肺癌(NSCLC)患者免疫治疗后发生甲状腺功能障碍(irTD)的相关危险因素并构建预测模型。 方法 回顾性分析2019年1月至2024年6月在安徽医科大学附属巢湖医院收治的197例接受免疫治疗的NSCLC患者资料,按7∶3比例分为训练集(n = 137)和验证集(n = 60)。通过Lasso和logistic回归筛选危险因素并构建动态列线图模型,采用ROC曲线、校准曲线、决策曲线(DCA)及临床影响曲线(CIC)评估模型效能。 结果 多因素分析显示性别(OR = 0.172,95% CI:0.047 ~ 0.623)、M分期(OR = 2.919,95% CI:1.063 ~ 8.015)、ln(SII)(OR = 0.167,95% CI:0.066 ~ 0.423)、ALC(OR = 3.395,95% CI:1.493 ~ 7.716)、TSH(OR = 1.464,95% CI:1.126 ~ 1.904)是irTD发生的独立危险因素,据此构建的模型公式为logit(P) = 9.261 - 1.760 × 性别 + 1.071 × M分期 - 1.787 × ln(SII) + 1.222 × ALC + 0.381 × TSH,该模型在验证集中的AUC达0.832(95%CI:0.719 ~ 0.945),与训练集结果相近。校准曲线显示预测概率与实际观察值具有良好的一致性,DCA和CIC证实该模型具有较好的临床应用价值。 结论 该研究确定了NSCLC患者免疫治疗后发生irTD的关键危险因素,所建立的动态列线图模型(网页计算器:https://lingchun.shinyapps.io/dynnomapp/)能够有效识别irTD高风险人群,为临床决策提供可靠的工具。

Abstract

Objective To explore the related risk factors for thyroid dysfunction (irTD) after immunotherapy in patients with non?small cell lung cancer (NSCLC) and to construct a predictive model. Methods A retrospective analysis was conducted on 197 NSCLC patients who received immunotherapy at Chaohu Hospital, Anhui Medical University between January 2019 and June 2024. The patients were divided into a training set (n = 137) and a validation set (n = 60) in a 7∶3 ratio. Risk factors were screened through Lasso and logistic regression, and a dynamic nomogram model was constructed. The model's performance was evaluated using ROC curve, calibration curve, decision curve analysis (DCA), and clinical impact curve (CIC). Results Multivariate analysis showed that Gender (OR = 0.172, 95% CI:0.047 ~ 0.623), M stage(OR = 2.919, 95% CI:1.063 ~ 8.015),ln(SII) (OR = 0.167, 95% CI:0.066 ~ 0.423), ALC (OR = 3.395, 95% CI:1.493 ~ 7.716), and TSH (OR = 1.464, 95% CI:1.126 ~ 1.904) were independent risk factors for the occurrence of irTD. The model formula based on these factors is: logit(P) = 9.261 - 1.760 × Gender + 1.071 × M stage - 1.787 × ln(SII) + 1.222 × ALC + 0.381 × TSH. The model achieved an AUC of 0.832(95%CI:0.719 ~ 0.945) in the validation set, which was similar to the results in the training set. The calibration curve demonstrated good consistency between the predicted probability and actual observed values. DCA and CIC confirmed that the model has good clinical applicability. Conclusion This study identifies key risk factors for the occurrence of irTD after immunotherapy in NSCLC patients. The dynamic nomogram model developed (web calculator: https://lingchun.shinyapps.io/dynnomapp/) can effectively identify high?risk populations for irTD, providing a reliable tool for clinical decision?making.
