Abstract

We refer to 48 adult patients suffering from acute myeloblastic leukemia, whose leukemic cells showed a typical cytochemical pattern: i.e. weak staining for peroxydase and with sudanblack B and lacking or only weak staining for nonspecific esterase. In 8 patients the leukemic myeloblasts additionally showed distinct granular staining for polysaccharides using the PAS-reaction. The therapeutic response, the remission rate and the survival time of these 8 cases have been compared to those of 40 patients, whose leukemic myeloblasts differed exclusively in the absence of granular PAS-positive materials. Out of the latter PAS-negative cases 7 patients (18%) went into a complete remission (M1, P1), 5 patients achieved partial remission (M2, P1-2), the 50%-survival time was 4.9 months. Out of the 8 granular PAS-positive cases 4 patients (50%) went into complete (M1, P1), and 1 reached partial remission (M2, P1-2). The 50%-survival time of the cases now lasts 10.1 months and three patients are still alive and in persisting complete remission 19, 12.5 and 12 months after diagnosis. These results suggest a better prognosis and an improved therapeutic response in those myeloblastic leukemias which additionally contain cytoplasmic granular...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.
