Comments section
Comments
The t(14;14)(q11;q32) CEBPE/IGH may be associated with good prognosis in B-ALL. In 4 cases with clinical follow-up, complete remission was achieved and those were alive at the time of report. In the case described herein, the t(14;14) was the sole anomaly, IGH rearrangement was detected but CEBPE involvement was not studied. This patient has well known bad prognostic features as high WBC count and CNS involvement and died few days after diagnosis.
