Head and neck cancer in transplant recipients

Purpose of review: Transplant recipients have an increased incidence of cancer compared with the general population. Head and neck sites are involved in more than 50% of patients, and as a result the otolaryngologist should be familiar with the diagnosis and management of posttransplant malignancies. Recent findings: Skin cancer is the most common malignancy encountered in the transplant population, and in areas of high sun exposure, as many as 80% of patients are affected. Patients who undergo liver transplantation for alcoholic cirrhosis appear to be at particularly increased risk for developing posttransplant malignancy of the head and neck. A number of uncommon malignancies such as Kaposi's sarcoma occur with a greatly increased incidence in transplant recipients. Malignancy in this patient population tends to present at a younger age compared with the general population, with a more aggressive course and poorer outcomes reported. Summary: A high index of suspicion may reduce morbidity and mortality through early detection of malignant disease in the transplant recipient.
