Objective: To report a case of massive blast infiltration of the liver by acute lymphoblastic leukemia (ALL) manifested by worsening liver function test (LFT) results and concern over how to dose chemotherapy in this patient.
Case summary: A 36-year-old male presenting with productive cough, abdominal pain, and lower back pain was diagnosed with pre-B cell ALL. Of note, the patient developed worsening LFT results within the first few days of diagnosis. Because of concern over increasing liver dysfunction and the need to administer vincristine and daunorubicin with induction therapy, a transvenous liver biopsy was performed, revealing massive lymphoblast infiltration.
Discussion: A short course of prednisone was given to determine whether the LFT abnormalities would reverse with treatment. Once a downward trend in the abnormalities was noted, full-dose induction chemotherapy was administered.
Conclusions: It is important to discern the cause of elevated LFT values in patients with acute leukemia who require induction chemotherapy, as this may affect treatment decisions and patient outcomes.
