Brief Summary:
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.

Condition or disease

Observational Model: Case-Only
Time Perspective: Prospective
Official Title: Evaluation of RFC Transporter & MTHFR SNP's, as Well as hEN1 and DCK Expression as Prognostic Factors in Patients With Acute Lymphoblastic Leukemia.
Study Start Date : December 2010
Estimated Primary Completion Date : December 2014

one cohort
Adult patients with ALL attending at the Instituto Nacional de Cancerologia Mexico.

Primary Outcome Measures :
  1. To evaluate clinical response [ Time Frame: December 2012 ]

  2. Clinical responses in relation with SNP's or gene expression [ Time Frame: clinical response. ]

Biospecimen Retention:   Samples With DNA
