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-eGFR, cystatin C only-eGFR, creatinine and cystatin C-eGFR) 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).
Background: Adult survivors of unilateral, nonmetastatic, non-syndromic Wilms tumor (WT) treated with whole abdomen radiation therapy (WART) are at risk for impaired kidney function. The impact of bias and accuracy on estimated glomerular filtration rate (eGFR) among adult survivors of WT has not been well documented.
Procedure: We clinically evaluated male and female WT survivors with creatinine and cystatin C, calculated eGFR using the Chronic Kidney Disease-Epidemiology equations with and without cystatin C, and measured Tc diethylenetriamine pentaacetic acid (DTPA) plasma clearance.
Purpose: Cancer-related worry (CRW; concerns related to cancer and its late effects) is prevalent among childhood cancer survivors. Elevated CRW has been associated with self-reported suboptimal physical activity. The aim of this investigation was to describe associations between CRW and objectively assessed physical activity in childhood cancer survivors.

This study examined the incidence of frailty among survivors at 10 or more years after diagnosis, frailty prevalence 5 years later, and risk factors for becoming frail.
Methods: Frailty was measured at study entry and 5 years later.
Background: Survivors of childhood cancer may be at increased risk for treatment-related kidney dysfunction. Although associations with acute kidney toxicity are well described, evidence informing late kidney sequelae is less robust.
Methods: To define the prevalence of and risk factors for impaired kidney function among adult survivors of childhood cancer who had been diagnosed ≥10 years earlier, we evaluated kidney function (eGFR and proteinuria).
Background: The impact of specific treatment modalities on long-term renal function and blood pressure among adult survivors of Wilms tumor (WT) has not been well documented.
Methods: Among 40 WT survivors and 35 noncancer controls, we estimated the glomerular filtration rate (eGFR) using the Chronic Kidney Disease-Epidemiology (CKD-EPI) equations with and without cystatin C, obtained 24-hour ambulatory blood pressure readings, and, among survivors only, measured Tc diethylenetriamine pentaacetic acid (DTPA) plasma clearance. Survivors were treated with unilateral nephrectomy and nonnephrotoxic chemotherapy.
Background: Few data define the dose-specific relation between alkylating agent exposure and semen variables in adult survivors of childhood cancer. We undertook this study to test the hypothesis that increased exposure to alkylating agents would be associated with decreased sperm concentration in a cohort of adult male survivors of childhood cancer who were not exposed to radiation therapy for their childhood cancer.
Methods: We did semen analysis on 214 adult male survivors of childhood cancer (median age 7·7 years [range 0·01-20·3] at diagnosis, 29·0 years [18·4-56·1] at assessment, and a median of 21·0 years [10·5-41·6] since diagnosis) who had received alkylating agent chemotherapy but no radiation therapy.
