Non-Hodgkin's lymphoma in a population with or at risk for acquired immunodeficiency syndrome: indications for intensive chemotherapy.

Objective: An increased risk of malignancies, including Kaposi's sarcoma and non-Hodgkin's lymphoma, is found in patients infected with the human immunodeficiency virus type 1 (HIV-1). Treatment of such patients may be complicated by their underlying immunodeficiency, especially when aggressive regimens are used. Clinical presentation and treatment outcomes were assessed in 31 patients with non-Hodgkin's lymphoma who had or were at risk for infection with HIV-1 at a single community institution.

Methods: Lymphomas presented in advanced stages and involved extranodal sites. Twenty-six patients received therapy (two radiation, one surgery), and a total of 23 patients received chemotherapy.

Results: A 52 percent response rate was seen with the use of chemotherapy. A history of opportunistic infections, or Kaposi's sarcoma, or both impacted negatively on the ability to achieve a complete response. Sixty-four percent of the 11 patients who received an intensive chemotherapeutic regimen, MACOP-B (methotrexate, Adriamycin, cyclophosphamide, vincristine, prednisone, bleomycin) had complete remissions. Overall median survival for 23 patients who received chemotherapy was seven months. Patients achieving complete responses had a median survival of 20 months.

Conclusions: Our results support intensive chemotherapy for patients with lymphoma and HIV-1 infection.
