MRCP2-2322
A 20-year-old woman presents with a 4-week history of fever, night sweats, and weight loss. On physical examination, she has hepatosplenomegaly. Her blood count reveals a WBC count of 130 ×109/L (4-11), a hemoglobin level of 68 g/L (115-165), and a platelet count of 21 ×109/L (150-400). A peripheral smear shows circulating blasts, which are confirmed to be B-ALL by flow cytometry immunophenotyping. Cytogenetics confirms positivity for BCR-ABL (Philadelphia chromosome). What is the most appropriate therapy to initiate at this point?
