Immunosuppressive therapy and Kaposi's sarcoma after kidney transplantation.
Immunosuppressive therapy for organ transplant recipients is complicated by high rates of malignant diseases, one of which is Kaposi's sarcoma (KS). Between November 1975 and March 2003, 1425 patients underwent renal transplantation at our center, including the 1095 most recent procedures. Fifty-two malignancies were observed in 50 patients (4.7%), including 16 cases of KS. The 16 recipients comprised 6 men and 10 women of mean age 39 +/- 9 years (range 10 to 62 years). At the time of KS diagnosis, 14 recipients were receiving cyclosporine, azathioprine, and prednisolone, and the other 2 azathioprine and prednisolone. The mean time from transplantation to diagnosis was 24 +/- 15.2 months (range 8 to 74 months). One recipient showed a lymphoma concomitant with KS. Seven patients had lesions limited to the skin, 5 had the skin and gastrointestinal tract disease, and 4 had disseminated disease. After KS was confirmed, the first-line treatment was cyclosporine and azathioprine withdrawal with tapering of prednisolone. The tumors were managed by appropriate surgical and/or medical therapy. At the time of this presentation, 9 individuals are alive, 4 with normal renal function. Five patients lost their grafts due to chronic rejection. We found that the combination of immunosuppressive drug withdrawal and chemotherapy is effective in patients with limited disease, but the results are poor in cases of generalized disease.
