Title: Total body irradiation and syngeneic marrow transplantation in an inbred rat model of acute myelogenous leukemia. [. gamma. rays; AML cell-marrow cell interactions in delayed relapse]

Journal Article · · Int. J. Radiat. Oncol., Biol. Phys.; (United States)

While acute myelogenous leukemia (AML) occurs rarely in laboratory animals, over 20 model systems have been reported. One of these, AML of the inbred Wistar/Furth rat, has been shown to be pathophysiologically similar to human AML. Ten days after intravenous inoculation of 1.0 x 10/sup 6/ cells of a tissue culture grown clonal line, rats demonstrated peripheral blood leukemia, replacement of greater than 90% of the bone marrow with distinctive malignant myeloblasts and a syndrome of hypermuramidase (lysozyme) emia and muramidasuria. Total body irradiation (TBI) at 10 days after leukemia cell passage with a marrow lethal dose (950 rad, 140 rad/min, /sup 137/Cs source, 663 kV) followed by intravenous inoculation of 5.0 x 10/sup 8//kg viable syngeneic bone marrow cells produced transient complete remissions. Repopulation with transplanted marrow was detected along with increasing numbers of recognizable W/Fu AML cells in peripheral blood, marrow, and central nervous system. The delayed leukemia relapse in irradiated transplanted rats compared to irradiated non-transplanted controls suggests an interaction between surviving W/Fu AML cells and transplanted marrow. This model may be of value in studies designing a therapeutic interaction against AML by donor marrow in the chemotherapy, immunotherapy, and total body irradiated patient.
