Methods
We studied adult heart transplant recipients from the Organ Procurement and Transplantation Network database (1987-2018). Kaplan-Meier survival analysis was performed to determine annual probabilities of developing DNM, excluding squamous and basal cell carcinoma. Rates were compared to the general population in the Surveillance, Epidemiology, and End Results database. Cox proportional hazards regression was performed to calculate hazard ratios for risk factors of DNM development, all-cause, and cancer-specific mortality.
