Abstract:
OBJECTIVE:To investigate the clinical manifestations and laboratory features of B-ALL patients with EP300-ZNF384 fusion gene positive, so as to improve the understanding of this subtype disease.
METHODS:The clinical data of 3 B-ALL patients with EP300-ZNF384 fusion gene positive admitted in Department of Hematology, the first medical center of Chinese PLA general hospital from February 2017 to February 2018 were collected and analyzed retrospectively. The clinical and laboratory characteristics as well as the therapentic outcome in B-ALL patients with EP300-ZNF384 fusion gene positive were analyzed.
RESULTS:The fusion gene of EP300-ZNF384 was detected in 8.1%(3/37) of B-ALL patients. All cases showed the normal karyotype and aberrant CD13 and/or CD33 expression for immunophenotype. 3 patients were sensitive to traditional chemotherapy.
CONCLUSION:The B-ALL with EEP300-ZNF384 fusion gene positive may be a subgroup of B-ALL with a uniqe clinical characteristis and laboatorial features. EP300-ZNF384 positive patients show a good response to conventional chemotherapy, suggesting a favorable prognosis.
