Renal function after autologous bone marrow transplantation.
Seventy-two out of 102 consecutive patients autografted for various hematologic and lymphoid malignancies had a relapse-free survival of greater than 6 months after autologous bone marrow transplantation (ABMT) and were evaluated for long-term effect of the treatment on the renal function. The myeloablative therapy included total body irradiation (TBI) in a single fraction of 7.5 Gy in 41/72 patients. Mean glomerular filtration rate (GFR) showed a significant decrease (p less than 0.01) and serum creatinine and serum urea an increase (p less than 0.05) 6 months after ABMT. Twelve of 72 patients (17%) developed renal dysfunction defined as greater than 25% decrease in GFR, in most cases accompanied by hematuria and proteinuria. Onset was 3-6 months after ABMT. Some patients have later improved considerably, but others continue to deteriorate in renal function. The single most important risk factor for renal dysfunction after ABMT was irradiation. Renal damage was most frequent in lymphoma patients conditioned with BEAC (carmustine [BCNU], etoposide, cytarabine, cyclophosphamide) followed by irradiation, suggesting that this drug combination might have potentiated the toxicity of irradiation. Nephrotoxic antibiotics probably contributed to renal damage in individual cases. Young age did not appear to be a risk factor. Our data indicate that combined treatment with BEAC and TBI should be used with caution and that renal function should be monitored in all patients after bone marrow transplantation to detect any new toxicity patterns of the various conditioning regimens currently used.
