Abstract

Objective: To analyze the prognostic value of CD7 expression in newly diagnosed acute myeloid leukemia (AML) patients, and to further explore the correlation between CD7 expression and CEBPA mutation, and to clarify the prognostic value of CD7(+) in AML patients with wild-type (WT) or mutant-type (MT) CEBPA. Methods: The clinical data of 298 newly diagnosed non-M(3) AML patients between January 2010 and December 2016 were analyzed retrospectively. The clinical characteristics and prognosis of CD7(+) and CD7(-) patients were respectively compared in all patients, and in patients with WT and MT CEBPA. The relationship between CD7 expression and CEBPA mutation was determined by chi-square, and the effects of CEBPA mutation on survival and prognosis in CD7(+) group by Kaplan-Meier method. Results: In CD7(+) group, the frequencies of CEBPA mutation were 10.1% (single site) and 33.9% (double site) , significantly higher than those of the CD7(-) group (5.3% and 4.2%) (P=0.000) . Subgroup prognostic analysis showed a lower CR rate (P=0.001) and a higher RR (P=0.023) in CD7(+) group comparing to those of CD7(-) group in AML patients with wild type CEBPA. There were no statistical difference between CD7(+) group and CD7(-) group in overa...Continue Reading

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.

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.
