RATIONALE: Studying the genes expressed in samples of blood from young patients with cancer treated with ifosfamide may help doctors identify risk factors for kidney damage.

PURPOSE: This clinical trial is looking at the CYP3A5 gene to see if having the gene may be a risk factor for kidney damage in young patients with cancer treated with ifosfamide.

Further study details as provided by National Cancer Institute (NCI):

Primary Outcome Measures:
  • CYP3A5 genotype
  • Renal function and nephrotoxicity
  • Relationship between CYP3A5 genotype and ifosfamide nephrotoxicity

Secondary Outcome Measures:
  • Comparison of measured glomerular filtration rate (GFR) with the Cole model

Estimated Enrollment: 300
Study Start Date: July 2007
Detailed Description:



  • To determine the CYP3A5 genotype in young patients with cancer who have received ifosfamide.
  • To document renal function and nephrotoxicity on one occasion between 1 month and 5 years after completion of ifosfamide treatment.
  • To determine the relationship between CYP3A5 genotype and ifosfamide nephrotoxicity.


  • To compare the measured glomerular filtration rate (GFR) (using a radioisotope clearance method) with that calculated using the Cole (weight and creatinine) model.

OUTLINE: This is a multicenter study.

Nephrotoxicity assessment is performed in patients who have not undergone prior assessment*.

NOTE: *Nephrotoxicity assessment is performed once between 1 month and 5 years after completion of ifosfamide chemotherapy.

All patients will undergo a single blood sample collection. DNA will be extracted from this sample and genotyped for the known functional polymorphisms in CYP3A5. The technique of restriction fragment length polymorphism (RFLP) will be used to detect any single nucleotide polymorphisms in CYP3A5.

DNA may be obtained from stored tumor samples from patients for whom the results of renal investigations are available, but for whom blood is not available for CYP3A5 genotyping.


Ages Eligible for Study:   up to 20 Years   (Child, Adult)

      • Patients who received CEV chemotherapy (carboplatin, epirubicin, and vincristine) on strategy 952 or 953 are not eligible
    • CCLG-EPSSG-RMS-2005


  • Clinically stable to undergo renal investigations
  • No pre-existing renal impairment (glomerular or tubular) prior to treatment with ifosfamide
  • No known nephrotoxicity for which nephrotoxic supportive treatment (aminoglycosides, amphotericin, acyclovir, cyclosporine, or tacrolimus) was a major contributory cause of renal damage


  • See Disease Characteristics
  • Recovered from the acute non-renal toxicity of the last course of chemotherapy
  • No other prior nephrotoxic chemotherapy (e.g., cisplatin, carboplatin, melphalan, or high-dose methotrexate)
  • No prior radiotherapy to a field including the kidneys
  • No prior removal of renal tissue
  • No concurrent ifosfamide
