Malignant lymphomas in HIV-seropositive patients. Frequency, features, and prognosis. Report on 31 cases.

In a random HIV-seropositive population, malignant lymphomas were diagnosed in 31 patients, of whom 24 (77%) had non-Hodgkin lymphoma (NHL) and 7 (23%) Hodgkin lymphoma (HL). The prevalence of NHL among AIDS patients was 8% (23/279 cases), with a prevalence of 17% among autopsied patients (16/96 cases). No patient with HL had AIDS at the time of diagnosis. In 7 of 23 AIDS patients with NHL (30%) the diagnosis was made only post mortem; among these were all 5 patients with primary CNS NHL. Median survival from the time of diagnosis was 1 month for patients with NHL and 3 months for those with HL. In individual patients, survival for several years may be possible with chemotherapy. Certain patients with NHL appear to benefit from intensive chemotherapy with a combination of methotrexate, doxorubicin, cyclophosphamide, vincristine, prednisone, and bleomycin (MACOPB protocol). Appropriate, therapeutic strategies taking into account the patients' individual conditions, including the overall prognosis, urgently requires development. Metastatic CNS involvement, which was the primary cause of death in 5 of 11 patients with NHL (45%) receiving chemotherapy, represents a serious limitation to successful treatment.
