Leukemia after liver transplant

Abstract

Introduction: Acute leukemia is rare after solid organ transplantation.

Methods: Review of data on 3 patients with acute leukemia identified among 1365 who underwent liver transplantation at our center, and a review of the literature.

Results: In patient 1, AML-M4 developed 19 months after transplant for cryptogenic cirrhosis. In patient 2, B cell acute lymphoid leukemia was diagnosed 10 months after liver transplant for fulminant hepatitis. Both patients had normal cytogenetics, and achieved complete remission with chemotherapy. In patient 3, acute monocytic leukemia-M3 with t(15;17) arose 18 months after transplant for hepatitis C cirrhosis. This patient received treatment with retinoic acid and chemotherapy, but developed a disseminated intravascular coagulation and died before completing therapy. No patient presented with chromosomal abnormalities commonly seen in secondary leukemia. The latency period to diagnosis after transplant was 10-19 months.

Conclusions: Acute leukemia, although rare after liver transplantation, should be considered in the differential diagnosis of hematological complications.
