Therapeutic Options to Decrease Actinic Keratosis and Squamous Cell Carcinoma Incidence and Progression in Solid Organ Transplant Recipients: A Practical Approach

Background Solid organ transplant recipients (SOTRs) have a 50 to 250 times greater risk of squamous cell carcinoma (SCC) than the general population and experience higher rates of invasive and metastatic disease. These greater risks are a product of the tumorigenic effects of their immunosuppressive medications. As the number of transplantations and the life expectancy of SOTRs increase, SCCs are becoming a major source of morbidity and mortality. Objective To present a practical approach for busy practicing clinicians to the care of SOTRs who are developing SCCs. Topics include assessment and treatment of new and neglected SOTRs; the dermatologist's role with the transplantation team; and practical considerations in the choice of topical agents, systemic agents, and immunosuppressive therapy manipulation. Methods and Materials An extensive literature search of the understanding of SCC pathophysiology and treatment in SOTRs was conducted. Results Presented here is a logical, concise guide to the care of SOTRs who are developing actinic keratoses and SCCs. Conclusion Proper assessment of patients, understanding therapeutic alternatives and their application, and early institution of preventative and adjuvant therapies can help to decrease skin cancerrelated morbidity and mortality in SOTRs.
