Abstract

Despite the marked progress in the procedure of allogeneic hematopoietic stem cell transplantation (allo- HCT) as a curative therapy for hematological malignancy, we still need to resolve issues in clinical laboratory testing for the assessment of transplant patients. For example, minimal residual disease (MRD) negativity before transplantation is known to be associated with good survival, but the widespread use of the multi-color flow cytometry system is needed for the routine assessment of MRD. In addition, we should apply an appropriate testing system for counting harvested bone marrow cells with careful consideration of the meas- urement principle of testing equipment because bone marrow is different from peripheral blood in its compo- sition of cells and components. It is also a problem that the short tandem repeat-polymerase chain reaction (PCR) for the evaluation of donor chimerism is not covered by Japanese national health insurance. Tissue biopsy is useful for the diagnosis of graft-versus-host disease, transplantation-associated microangi- opathy, and sinusoidal obstruction syndrome. It is, however, potentially dangerous for patients who have thrombocytopenia after allo-HCT to undergo a biopsy. Non-invasive tests incl...Continue Reading

Allogenic & Autologous Therapies

Allogenic therapies are generated in large batches from unrelated donor tissues such as bone marrow. In contrast, autologous therapies are manufactures as a single lot from the patient being treated. Here is the latest research on allogenic and autologous therapies.

Blood And Marrow Transplantation

The use of hematopoietic stem cell transplantation or blood and marrow transplantation (bmt) is on the increase worldwide. BMT is used to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Here is the latest research on bone and marrow transplantation.
