ABSTRACT
Allogeneic hematopoietic stem cell transplantation (allo-HSCT) in the treatment of leukemia patients can improve overall survival and disease-free survival, and reduce relapse. Although the allo-HSCT is more widely used in the treatment of leukemia, but the graft-versus-host disease (GVHD) and cytomegalovirus (CMV) infections are the common complications, and are the major cause of mortality for patients following allo-HSCT. Previous studies showed that there might be a mutual promotive relationship between GVHD and CMV infection, but the clear relationship remained to be elucidated. The relationship of GVHD and CMV has been the focus of clinical research. Recently, a great progress has been made on researches of the relationship and its mechanism between GVHD and CMV infection. In this article, the relationship and its mechanism between GVHD and CMV infection after allo-HSCT are reviewed.

In recent years, standardized treatment based on the risk stratification has been applied to clinical diagnosis and treatment of leukemia, which significantly improves the remission rate of ALL. However, relapse after remission remains an important challenge for long term efficacy. Chromosomal karyotype analysis is often used clinically to study the genetic features of ALL. As leukemia-specific markers, the cytogenetic and molecular genetic abnormalities can be used to evaluate prognosis and make an effective and optimal therapy. Furthermore, they are also used to track minimal residual disease. Therefore, the cytogenetic and molecular genetic abnormalities may become a monitor and a new target for the treatment of leukemia. This review briefly introduces the structure and physiological function of B-ALL associated cytogenetic and molecular genetic abnormalities, focusing on their prognostic effect on B-ALL.
