Background and objectives Because little is known about long-term treatment-related nephrotoxicity, the aim was to determine risk factors for renal impairment long after childhood cancer treatment. Design, setting, participants, & measurements Data from 763 adult childhood cancer survivors (414 men) were obtained during regular visits at the late-effects clinic between 2003 and 2009. Median follow-up time was 18.3 years (range=5.0-58.2). Glomerular function was assessed by estimated GFR (using the Modification of Diet in Renal Disease formula), urinary albumin creatinine ratio, and tubular function by urinary β2-microglobulin creatinine ratio. The associationwith treatment factorswas analyzedwith covariance analysis for estimated GFR and logistic regression for urinary albumin and urinary β2-microglobulin creatinine ratios. Results Survivors treated with nephrectomy and abdominal irradiation had significantly lower estimated GFR than survivors not treated with nephrectomy/abdominal irradiation (estimated mean=90 ml/min per 1.73 m2 versus 106, P<0.001). Estimated GFR was significantly lower in survivors after treatment with high-dose ifosfamide (88 versus 98, P=0.02) and high-dose cisplatin (83 versus 101, P=0.004) compared with survivors not treated with these regimen. Nephrectomy combined with abdominal radiotherapy (odds ratio=3.14, 95% confidence interval=1.02; 9.69) and high-dose cisplatin (odds ratio=5.19, 95% confidence interval=1.21; 22.21) was associated with albuminuria. High-dose ifosfamide (odds ratio=6.19, 95% confidence interval=2.45; 15.67) was associated with increased urinary β2-microglobulin creatinine ratio. Hypertension was present in 23.4% of survivors and 31.4% of renal tumor survivors. Conclusions Treatment with unilateral nephrectomy, abdominal radiotherapy, cisplatin, and ifosfamide was associated with lower estimated GFR. Persisting tubular damage was related to ifosfamide treatment.
