Non‐Melanoma Skin Cancer in Transplant Recipients: A Single‐Centre Retrospective Cohort Study on the Role of Transplant Type, Immunosuppressive Exposure, and Tumor Subtypes

In this long-term cohort, NMSC risk increased with age at first transplant, whereas transplant organ and ever-use of major immunosuppressive agents were not independently associated in adjusted models. Over an extended follow-up, NMSC accumulated steadily, with crude incidence rates around 1.88-2.68 cases per 100 person-years across immunosuppressive classes and agents, underscoring the cumulative nature of skin cancer risk under chronic immunosuppression. Our results reinforce the need for sustained, long-term dermatologic surveillance, particularly in older patients undergoing transplantation.
