  "abstract": "Background and objective: Progressive disease (PD) in differentiated thyroid cancer patients with lung metastases (DTC-LM) poses a significant clinical challenge, yet reliable predictive tools remain limited. This study aimed to develop and validate a nomogram for individualized prediction of 5-year progression-free survival (PFS) probability in DTC-LM patients.\n\nMethods: This retrospective study included 284 DTC-LM patients from two institutions, divided into a training cohort (Qingdao cohort, n = 184) and an external validation cohort (Shanghai cohort, n = 100). Patients were classified as having PD or non-PD (NPD) at final follow-up. Univariable and multivariable Cox proportional hazards regression analyses were used to identify independent predictors of PD. A nomogram based on the multivariable Cox model was developed to estimate 5-year PFS probability. Model performance was evaluated using the C-index, calibration curves, and decision curve analysis (DCA).\n\nResults: Multivariate analysis identified age upon diagnosis (≥55 years), tumor size, pre-ablation stimulated thyroglobulin (Ps-Tg ≥528.5 ng/mL), and initial RAI avidity status as independent predictors of PD. The 5-year PFS probability nomogram demonstrated excellent discrimination, with a C-index of 0.874 in the training cohort and 0.769 in the external validation cohort. Calibration curves showed good agreement between predicted and observed outcomes, and DCA confirmed favorable clinical net benefit.\n\nConclusion: This nomogram incorporating four readily available clinical variables showed good discrimination for predicting 5-year PFS probability in DTC-LM patients and may facilitate preliminary risk stratification and timely therapeutic decision-making.",
