Brief Summary

A Randomized Controlled Trial of Topical 5% Niacinamide for Skin Cancer Prevention in Organ Transplant Recipients This study is designed to evaluate whether a topical 5% niacinamide cream can help prevent skin cancer in organ transplant recipients. Individuals who have received an organ transplant have a much higher risk of developing precancerous skin growths and skin cancers because of long-term immune-suppressing medications. Although sunscreen is an important part of sun protection, additional preventive approaches are needed. Early research suggests that niacinamide may help protect the skin, and this trial will examine whether a topical formulation provides benefit in this high-risk group. The study will test whether daily use of topical 5% niacinamide reduces the number of actinic keratoses over 6 and 12 months and whether it decreases the development of new keratinocyte cancers when compared with sunscreen alone. The study will also evaluate how well the topical product is tolerated and whether it can be used consistently as part of a daily skin-care routine. A total of 20 adult organ transplant recipients with a history of multiple actinic keratoses and at least one prior non-melanoma skin cancer will enroll in this 12-month, randomized, controlled trial. Participants will be assigned to receive either daily topical 5% niacinamide plus sunscreen or sunscreen alone. Skin examinations will be performed at 6 and 12 months using standardized mapping methods. Information on treatment tolerability, adherence, and any side effects will be collected through structured surveys, and any lesions suspicious for cancer will be evaluated by a board-certified pathologist.
