Biomarkers in Predicting Neurotoxicity in Patients With Colorectal Cancer Receiving Oxaliplatin
Recruitment status was: Recruiting
RATIONALE: Studying samples of blood in the laboratory from patients receiving oxaliplatin for cancer may help doctors learn more about changes that occur in DNA and identify biomarkers related to neurotoxicity.
PURPOSE: This phase II trial is studying biomarkers in predicting neurotoxicity in patients with colorectal cancer receiving oxaliplatin.

|Official Title:||Characterization and Research of Predictive Markers of Neurotoxicity During Treatment With Oxaliplatin in Colorectal Carcinoma: a Genetic and Proteomic Approach. Phase II Multicenter Study|
- Correlation of genetic profiles and peptide, protein, and neurotrophic factors with neurological toxicity
|Study Start Date:||September 2007|
|Estimated Primary Completion Date:||August 2009 (Final data collection date for primary outcome measure)|
- Correlate predictive genetic, proteomic, and/or neurotrophic markers with neurological manifestations related to the administration of oxaliplatin in patients with colorectal carcinoma.
- Differentiate between risk factors predictive of acute and chronic neurotoxicity.
- Establish a possible relationship between acute and chronic neurotoxicity.
OUTLINE: This is a multicenter study.
Patients receive oxaliplatin every 2 weeks as part of a FOLFOX chemotherapy regimen.
Blood samples are collected 15 days prior to beginning chemotherapy, prior to each course of chemotherapy, and at 1 month after completion of chemotherapy for pharmacogenetic and laboratory biological studies. Patients with chronic neurotoxicity undergo additional blood sample collection at 3, 6, 9, and 12 months after completion of chemotherapy. Samples are analyzed for the detection of gene variants involved in the oxalate and fluorouracil metabolic pathway; neurotrophic factors; proteomic analysis of plasma proteins and peptides; and for biological testing of neurotoxicity.
