RESUMO
Minimal residual disease (MRD) has been used for warning of relapse and guiding the therapy selection for hematological malignancies including acute leukemia. Based on MRD-related content reported at the 64th American Society of Hematology (ASH) Annual Meeting, this article discusses the progress of MRD-directed individualized therapy for hematological malignancies with a primary focus on acute myeloid leukemia.
RESUMO
A 10-year-old boy with severe aplastic anemia was admitted for allogeneic hematopoietic stem cell transplantation. After conditioning chemotherapy using cyclophosphamide, fludarabine, and antithymocyte immunoglobulin, he presented with fever and abdominal pain on day 0 of stem cell transplantation. After diagnosis of acute appendicitis with minor perforation, appendectomy was performed just after cell infusion. A week after the procedure, he showed two huge liver abscesses in S4 and S6 segments. We used broad spectrum antibiotics along with antifungal agents. Percutaneous drainage was attempted, but no fluid was removed and no microorganisms were isolated. After 7 weeks of antibiotics and antifungal therapy, liver abscesses showed improvement. We report a case of successfully treated appendicitis with liver abscesses in a severely neutropenic patient during allogeneic hematopoietic stem cell transplantation.
