Chronic Myeloid Leukemia After Living Donor Liver Transplantation

Chronic myeloid leukemia following liver transplantation: A case report

Long-term utilization of immunosuppression in organ transplant recipients leads to decreased immune-mediated tumor surveillance and increased risk of developing malignant tumors. However, chronic myeloid leukemia (CML) following living donor liver transplantation (LDLT) is rarely reported. The current case report presents a 42-year-old male patient who developed CML 14 months following LDLT. The patient achieved complete hematologic remission and early molecular response at 3 months imatinib treatment and major molecular response at 12 months imatinib treatment. The pathogenesis, risk factors, treatment and prognosis for CML following liver transplantation are unclear. Therefore, further analysis through accumulation of cases will be of great importance to prevent and treat this rare complication following liver transplantation.

Clinical lessons to be learned from patients developing chronic myeloid leukemia while on immunosuppressive therapy after solid organ transplantation: yet another case after orthotopic heart transplantation

Chronic myeloid leukemia developing after transplantation of solid organs and concomitant immunosuppression is a rare but still significant clinical phenomenon. We here describe an additional case of a 62-year-old male patient developing CML after orthotopic heart transplantation and medication with cyclosporine A, mofetil-mycophenolate, and steroids. Initial antileukemic therapy was imatinib at a standard dose and within 15 months of therapy a complete cytogenetic response was noted. In this report we discuss the clinical implications of these rare but biologically important cases.
