Predicting a metachronous cutaneous squamous cell carcinoma: a competing-risk model based on nationwide linked registries

this competing-risk model provides individualized, well-calibrated absolute risk estimates for a first metachronous CSCC. Based on routinely available clinical features, it offers insight into how established predictors shape risk in this high-susceptibility population and quantifies relative risk acceleration. External validation and the identification of novel predictors are necessary to further refine the model and support personalized surveillance strategies.
