Article Abstract

A 67-year-old woman diagnosed with adult T-cell leukemia/lymphoma received an induction chemotherapy and showed a partial response. She then underwent allogeneic peripheral blood stem cell transplantation from an HLA-identical sibling donor. Although cyclosporine (CS) was stopped at 120 days after transplantation, chronic graft-versus-host disease (cGVHD) of the skin developed. She was treated with a topical steroid, without exacerbation of the GVHD. She was admitted to our hospital due to the sudden development of pancytopenia at 212 days after the transplantation. She had an EB virus-associated post-transplant lymphoproliferative disorder (PTLD) in the hilum of the lung. The cGVHD of the skin resolved after the administration of prednisolone and CS. However, pancytopenia and PTLD persisted. Treatment with four cycles of rituximab (4×375 mg/m/week) led to the complete resolution of PTLD, but transfusion-dependent cytopenia did not improve. Secondary engraftment failure was diagnosed, and granulocyte colony-stimulating factor (G-CSF) and eltrombopag (100 mg/day) were administered, leading to gradual improvement of pancytopenia. It was observed that persistent pancytopenia was caused by secondary engraftment failure due to cGVHD in this case. This case suggested that the treatment with G-CSF and eltrombopag is effective for cGVHD-associated secondary engraftment failure.
