Abstract

To explore the influence of relapse and survival by chronic graft versus host disease (cGVHD) in patients with acute myeloid leukemia (AML) after allogeneic hematopoietics stem cell transplantation (allo-HSCT). Fifty-five AML patients received allo-HSCT were retrospectively reviewed. Relapse rate and overall survival (OS) were analyzed according to cGVHD. cGVHD significantly decreased the relapse rate of AML patients after transplantation within 2 years when compared with those without cGVHD (8.7% vs 38.6%, P=0.019), however, cGVHD had no effect on the long-term relapse rate (22.8% vs 5.9%, P=0.217). cGVHD had no effect on OS within 2 years (78.3% vs 61.0%, P=0.155) but could decrease the rate of long-term survival (63.7% vs 100%,P=0.01). cGVHD also could reduce the rate of relapse (8.3% vs 46.2%, P=0.044) and enhanced the rate of survival (83.3% vs 47.2%, P=0.045) in patients with high risk AML after allo-HSCT in 2 years, while it had no effect on the relapse rate and OS in patients with low and intermediated risk AML in early and late phase. Moreover, compared with the rate of relapse(38.6%) in patients without cGVHD, the rate of relapse were lower in patients with limited cGVHD and intensive cGVHD (27.3% and 31.3%, respectiv...Continue Reading

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.

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.

Acute Myeloid Leukemia

Acute myeloid leukemia (AML) is a clinically and genetically heterogeneous disease with approximately 20,000 cases per year in the United States. AML also accounts for 15-20% of all childhood acute leukemias, while it is responsible for more than half of the leukemic deaths in these patients. Here is the latest research on this disease.
