Chromosomal sensitivity of lymphocytes from individuals with therapy-related acute nonlymphocytic leukemia

Abstract

A small fraction of those individuals exposed to cytotoxic chemotherapy or radiation for the treatment of a primary malignant disease will develop a second malignancy some time later. Although exposure to the cytotoxic agents is believed to be the causative factor, the reason only certain individuals develop the second malignancy is unknown. Some studies have suggested that these individuals might be predisposed to cancer because of an inherent sensitivity to the alkylating agents used in cancer therapy. We have reported that these individuals with therapy-related acute nonlymphocytic leukemia (t-ANLL) have reduced endogenous levels of the repair protein O6-alkylguanine alkyltransferase (AGT). To further investigate the etiology of this disease, alkylation-induced sister-chromatid exchange (SCE) formation in individuals who developed second malignancies, was compared to other patient groups and normal controls. Peripheral blood lymphocytes from patients with (1) t-ANLL, (2) primary forms of acute nonlymphocytic leukemia (ANLL de novo), (3) patients with primary malignancies at risk of developing secondary disease, and (4) unexposed, healthy controls were treated in vitro with N-methyl-N'-nitro-nitrosoguanidine or mitomycin C.

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.
