Treatment of patients with AIDS-associated lymphoma is achieving inferior results when compared with outcomes for non-AIDS patients. Treatment with mBACOD has been promising, but the toxicity is very high. Patients treated with mBACOD have very low white blood cell counts. GM-CSF has increased the number of white blood cells in animal studies and preliminary human studies. It is hoped that including GM-CSF among the drugs given to lymphoma patients will prevent or lessen the decrease in white blood cells caused by mBACOD.
