RFC and MTHFR SNPs & hENT1- dCK Expression as Prognostic Factors in ALL & hENT1- dCK Expression as Prognostic Factors in AML
This trial is active, not recruiting.
|Conditions||acute lymphoblastic leukemia., acute myeloblastic leukemia|
|Sponsor||National Institute of Cancerología|
|Start date||December 2010|
|End date||December 2014|
|Trial size||50 participants|
|Trial identifier||NCT01307241, 010/020/ICI|
Results of actual treatment in ALL are not optimal. New prognostic factors, which may determine clinical & molecular response are required. Hyper-CVAD is an internationally accepted schema for such patients. The objective of this pilot study is to evaluate polymorphisms regarding RFC (reduced folate carrier) and MTHFR enzyme, which may affect the function of these proteins, and therefore the intracellular bioavailability of methotrexate. Also, the expression levels of hENT1 and dCK will be evaluated, since such genes codify for citarabine intracellular transport and activation, respectively. Clinical characteristics will be tabulated and analyzed for responders & non-responders patients. Uni- & multivariate analysis will be done to evaluate factors influencing on response and survival.
Adult patients with ALL attending at the Instituto Nacional de Cancerologia Mexico.
