The five-year experience with 75 consecutive splenectomies has been reviewed. Special detail was given to eight critically ill hypersplenic patients. Their diagnoses included Hodgkin's disease, lymphoma, leukemia, myelofibrosis and Felty's syndrome. Three presented with sepsis, two with anemia not responsive to transfusion, three had pathologic bleeding and two could not receive additional needed therapy of underlying disease because of low counts. All cases responded to splenectomy favorably. Hypersplenism is primarily a loss of balance between the splenic destruction-sequestration and bone marrow production. The demonstrated rapid consumption of transfused cells and some degree of functional reserve of the bone marrow is the prerequisite and clue for splenectomy response in critically ill patients.

In recent years, the role of epigenetic modifications in tumorigenesis drawn more and more attention. The aberrant changes of histone modifications have been found in leukemias, whereby loss of balance in H3K9 methylation is associated closely with leukemogenesis. SUV39H1, the first described histone H3 lysine 9 methyltransferase takes part in heterochromatin formation and gene transcription regulation. It could be a new target for leukemia therapy by correcting the aberrance of H3K9 methylation, inducing the reexpression of tumor suppressor genes. This review discusses how H3K9 methylation regulating gene transcription, silencing gene expression and its association with leukemia.
