Malignancies following lung transplantation.
During the last 2 decades, long-term survival after lung transplantation has significantly improved. However, among the complications related to the continuous administration of immunosuppressive drugs, malignancy plays an important role. We retrospectively revisited our series of patients to report our experience. From January 1991 we performed 134 lung transplantations in 128 recipients (mean age, 33.4 +/- 13.5 years). In all patients the first-line immunosuppressive regimen was based on a calcineurin inhibitor (cyclosporine or tacrolimus), an antimetabolic agent (azathioprine), and steroids. Five patients (4.2%) developed malignancy and the mean time of occurrence after the transplantation was 46.4+/-23 months. The mean age was 41 +/- 16 years (P = not significant [ns]). The tumors were as follows: laryngeal cancer (radiotherapy), colon cancer (surgery plus adjuvant chemotherapy), gastric cancer (surgery plus adjuvant chemotherapy), endobronchial non-Hodgkin lymphoma (NHL) (endoscopic resection plus chemoradiotherapy), and cutaneous and visceral Kaposi's sarcoma (KS) (chemotherapy). All patients have reduced the dose of immunosuppressive drugs; in 1 of them, tacrolimus was changed to rapamycin. Two patients died because of neoplastic dissemination, another 1 due to obliterans bronchiolitis. The 2 patients with NHL and KS are alive at 6 and 9 months, respectively, without signs of recurrence. Malignancies after lung transplantation represent an important problem. A multidisciplinary approach is mandatory to obtain satisfactory results in terms of improved quality of life and long-term survival.
