A Phase III Randomized Trial of Low-Dose Versus Standard-Dose mBACOD Chemotherapy With rGM-CSF for Treatment of AIDS-Associated Non-Hodgkin's Lymphoma

Summary

To determine the impact of dose intensity on tumor response and survival in patients with HIV-associated non-Hodgkin's lymphoma (NHL). HIV-infected patients are at increased risk for developing intermediate and high-grade NHL. While combination chemotherapy for aggressive B-cell NHL in the absence of immunodeficiency is highly effective, the outcome of therapy for patients with AIDS-associated NHL has been disappointing. Treatment is frequently complicated by the occurrence of multiple opportunistic infections, as well as the presence of poor bone marrow reserve, making the administration of standard doses of chemotherapy difficult. A recent study was completed using a low-dose modification of the standard mBACOD (cyclophosphamide, doxorubicin, vincristine, bleomycin, dexamethasone, methotrexate ) treatment. A 46 percent response rate was observed in patients treated with this combination of chemotherapeutic agents, with a number of durable remissions and reduced toxicity when compared to previous experience with more standard treatments. A subsequent study showed similar effectiveness using a lower dose of methotrexate administered on day 15. It is hoped that the use of sargramostim (granulocyte-macrophage colony-stimulating factor; GM-CSF) will improve bone marrow function and allow for administration of a higher dose of chemotherapy.
