RESUMEN
An 82-year-old man with Philadelphia chromosome-negative acute lymphoblastic leukemia (ALL) complicated by hepatocarcinoma was presented. Remission induction therapy of hyper-CVAD with half dose reduction achieved hematological complete remission (CR), but accompanied with elevated alanine aminotransferase and hyperbilirubinemia. The patient was thought intolerable for hyper-CVAD with half dose reduction due to liver toxicity, and treatment was switched to blinatumomab. Hematological CR was sustained after nine cycles of blinatumomab without exacerbation of liver dysfunction. After five courses of blinatumomab, hepatocarcinoma was treated successfully by trans-arterial chemoembolization. Two years after the diagnosis of ALL, the patient was alive in CR status of ALL.
