Nephrotoxicity Surveillance for Childhood and Young Adult Survivors of Cancer: Recommendations From the International Late Effects of Childhood Cancer Guideline Harmonization Group.

PURPOSE: Childhood, adolescent, and young adult (CAYA) survivors of cancer are at risk of nephrotoxicity. Surveillance guidelines are important for timely diagnosis and treatment of these survivors, which could slow the progression to higher stages of kidney dysfunction. METHODS: The International Late Effects of Childhood Cancer Guideline Harmonization Group established a multidisciplinary panel of 34 experts from 11 countries. The panel performed systematic literature reviews for articles published between 1990 and June 2023, graded the evidence using Grading of Recommendations Assessment, Development, and Evaluation methodology, and formulated recommendations based on evidence, clinical judgment, and consideration of benefits and harms of surveillance. Recommendations were critically appraised by two independent external experts and patient representatives. RESULTS: Glomerular dysfunction surveillance is recommended every 2-5 years for survivors treated with ifosfamide, cisplatin, abdominal radiotherapy, total body irradiation, or nephrectomy and is reasonable after carboplatin treatment. We recommend screening for glomerular dysfunction using an estimated glomerular filtration rate (eGFR) equation that includes serum creatinine, preferably combined with serum cystatin C if available. Tubular dysfunction surveillance is recommended once at entry into long-term follow-up and with follow-up as clinically indicated for survivors treated with ifosfamide and is reasonable after cisplatin treatment. CONCLUSION: These recommendations inform routine, uniform long-term follow-up care for CAYA survivors of cancer at risk of nephrotoxicity.
