INTRODUCTION: Increased survival in lung transplant recipients, the need for immunosuppressive therapy, and many risk factors before and after transplantation enhance the development of malignancies. This study sought to analyze the incidence of noncutaneous tumors after lung transplantation in our hospital, the risk factors for malignancy, and its impact on prognosis.
PATIENTS AND METHODS: A retrospective analysis of clinical records of patients after lung transplantation in our hospital from October 1993 to December 2014.
RESULTS: The study population included 443 patients. In total, 35 neoplasia developed in 33 patients (9.6%). Twelve cases were posttransplant lymphoproliferative disorders (PTLDs), 7 localized in the native lung, 7 gynecologic neoplasia (2 in the breast, 4 in the vulva, and 1 in the cervix), 3 in the colon, 2 in the nervous system (one was an astrocytoma), 2 in the prostate, 1 in the kidney, and 1 in the esophagus. The average time between transplantation and malignancy detection was 52.7 ± 45.4 months, being earlier in patients with PTLDs than in non-PTLD. Eleven patients who developed malignancy (all patients with neoplasia in native lung and in cervix, 1 in the colon, 1 PTLD, and 1 in the nervous system) died as a result of it. The only factor associated with an increased risk of malignancy in our population was smoking history.
CONCLUSIONS: Almost 10% of lung transplant recipients developed some type of noncutaneous neoplasia and the most frequently diagnosed were PTLDs. Lung neoplasia compromised most survival in these patients.
