BACKGROUND.
Renal transplant recipients have a high incidence of cancer. The main side effect of cisplatin, nephrotoxicity, has special implications in renal transplant recipients. This is particularly true in view of the routine use of cyclosporine as an inimunosuppresant. Nephrotoxicity is also one of the main side effects of cyclosporine.
METHODS.
We report a patient with a renal allograft who was receiving cyclosporine for immunosuppression and developed metastatic transitional cell carcinoma of the bladder and was treated with cisplatin-based chemotherapy. The literature regarding cisplatin-containing chemotherapy in patients with different cancers and a single transplanted kidney is reviewed.
RESULTS.
The patient received four cycles of methotrexate. vinblastine, doxorubicin, and cisplatin while on continuous cyclosporine therapy. His renal function remained stable. He responded to chemotherapy initially, but this response was short. Ten patients with renal transplants and cancer who were treated with cisplatin have been reported previously. Two were maintained on cyclosporine for immunosuppression throughout chemotherapy. No patient developed renal failure during or shortly after administration of cisplatin. Two of five patients treated for testicular cancer developed renal failure at 3 and 6 years after completion of chemotherapy. However, in both cases the cause of renal failure was attributed to chronic rejection of the transplanted kidney. 11 mo 6 mo 8 mo 8 mo 2 mo It 3 yr after chemotherapy No No 6 yr after chemotherapy No No No No No No No Cs: cyclosporise; A: azathioprine; Pr:
