Successful unrelated cord blood transplantation in Philadelphia chromosome positive acute lymphoblastic leukemia during pulmonary aspergillosis treated by anti-fungal therapy, granulocyte colony-stimulating factor-mobilized granulocytes and surgical resection: case report.
A 3-year-old girl with Philadelphia chromosome positive acute lymphoblastic leukemia developed pulmonary aspergillosis during severe neutropenia by re-induction therapy. She was treated by intravenous fluconazole, oral itraconazole with plasma level monitoring and surgical resection of the focus for 3 months after clinical diagnosis of fungal infection was made. Once she had recovered from surgery we attempted to induce remission with anti-fungal treatment. She developed fever and neutropenia and appeared unlikely to remit with conventional chemotherapy. Unrelated one-antigen-mismatched cord blood (CB) transplantation was performed 2 months after the induction therapy. Her pulmonary aspergillosis was reactivated during subsequent conditioning. Anti-fungal drugs were switched to amphotericin B and granulocyte colony-stimulating factor-mobilized granulocyte concentrates were transfused. She obtained engraftment and has maintained complete hematological and molecular remission without signs of aspergillus infection for 13 months so far after transplantation. Even very high-risk transplantation in pediatric patients could be successfully supported by carefully designed intense comprehensive medical care.
