BACKGROUND: Childhood cancer survivors experience adverse drug events leading to
lifelong health issues. The Applying Biomarkers to Minimize Long-Term Effects of
Childhood/Adolescent Cancer Treatment (ABLE) team was established to validate and
apply biomarkers of cancer treatment effects, with a goal of identifying children
at high risk of developing cancer treatment complications associated with
thrombosis, graft-versus-host disease, hearing loss, and kidney damage. Cisplatin
is a chemotherapy well known to cause acute and chronic nephrotoxicity. Data on
biomarkers of acute kidney injury (AKI) and late renal outcomes in children
treated with cisplatin are limited. OBJECTIVE: To describe the design and methods
of the pan-Canadian ABLE Nephrotoxicity study, which aims to evaluate urine
biomarkers (neutrophil gelatinase-associated lipocalin [NGAL] and kidney injury
molecule-1 [KIM-1]) for AKI diagnosis, and determine whether they predict risk of
long-term renal outcomes (chronic kidney disease [CKD], hypertension). DESIGN:
This is a 3-year observational prospective cohort study. SETTING: The study
includes 12 Canadian pediatric oncology centers. PATIENTS: The target recruitment
goal is 150 patients aged less than 18 years receiving cisplatin. Exclusion
criteria: Patients with an estimated glomerular filtration rate (eGFR) <30
mL/min/1.73 m(2) or a pre-existing renal transplantation at baseline.
MEASUREMENTS: Serum creatinine (SCr), urine NGAL, and KIM-1 are measured during
cisplatin infusion episodes (pre-infusion, immediate post-infusion, discharge
sampling). At follow-up visits, eGFR, microalbuminuria, and blood pressure are
measured and outcomes are collected. METHODS: Outcomes: AKI is defined as per SCr
criteria of the Kidney Disease: Improving Global Outcomes (KDIGO) guidelines. CKD
is defined as eGFR <90 mL/min/1.73m2 or albumin-to-creatinine ratio?3mg/mmol.
Hypertension is defined as per guidelines. Procedure: Patients are recruited
before their first or second cisplatin cycle. Participants are evaluated during 2
cisplatin infusion episodes (AKI biomarker validation) and at 3, 12, and 36
months post-cisplatin treatment (late outcomes). LIMITATIONS: The study has a
relatively moderate sample size and short follow-up duration. There is potential
for variability in data collection since multiple sites are involved.
CONCLUSIONS: ABLE will provide a national platform to study biomarkers of late
cancer treatment complications. The Nephrotoxicity study is a novel study of AKI
biomarkers in children treated with cisplatin that will greatly inform on late
cisplatin renal outcomes and follow-up needs.
