Fluroscent in situ hybridization analysis indicated presence of t(12;21)(p13;q22) translocation and near-tetraploidy in a case who 11-year-old boy and diagnosed with B precursor acute lymphoblastic leukemia (ALL). Although, some studies suggest good prognostic effect of translocation t(12;21) (p13;q22), there were very little data regarding the prognostic effect of Near- tetraploidy. Here we discussed the prognostic relevance of both t(12;21)(p13;q22) translocation and near tetraplody in Pre-B ALL.
