BACKGROUND: The relationships among treatment exposures, body composition, and estimated glomerular filtration rate (eGFR) in adult survivors of Wilms tumor have not been well studied.
METHODS: We evaluated body composition with dual-energy x-ray absorptiometry (DXA) and eGFR with the updated Chronic Kidney Disease Epidemiology Collaboration equations (creatinine only-eGFRCr, cystatin C only-eGFRCysC, creatinine and cystatin C-eGFRCr+CysC) without race in 134 adults previously treated for unilateral, non-syndromic Wilms tumor at St. Jude Children's Research Hospital between 1964 and 2004 with chemotherapy and with (hemiabdomen [HA] or whole abdomen [WA]) or without radiation therapy (RT). Z-scores for DXA variables were calculated using data from the National Health and Nutrition Examination Survey.
RESULTS: WART was associated with a lower relative total (p = 0.004) and trunk (p < 0.001) lean mass, eGFRCr (p = 0.008), eGFRCysC, (p < 0.001), and eGFRCr+CysC (p < 0.001), and higher values of cystatin C (p < 0.001). Linear regression demonstrated that relative total lean mass (p = 0.009) and relative trunk lean mass (p < 0.001) Z-scores, and eGFRCr (p = 0.013) were lower among those who received WART compared to No RT patients.
CONCLUSIONS: WART is associated with lower relative total and trunk lean mass Z-scores and eGFR, regardless of the equation used, and is lower in survivors treated with WART compared to unirradiated survivors of unilateral, non-syndromic WT. Assessments using other GFR measures may provide greater insight into the mechanism and magnitude of kidney function loss among WART-treated WT survivors.
