 AB    PURPOSE: Conventional therapy--ie, treatment with corticosteroids and
       cranial radiotherapy (RT)--is inadequate to treat AIDS-related primary
       central nervous system lymphoma (PCNSL), as it achieves a median
       survival of only 2 to 5 months. Chemotherapy added to RT in non-AIDS
       PCNSL improves disease control and prolongs survival. We studied the
       efficacy of this approach with RT in AIDS-related PCNSL. METHODS: Ten
       AIDS patients with PCNSL were treated with chemotherapy--nine at
       diagnosis and one at recurrence. None had evidence of systemic lymphoma.
       All patients treated at diagnosis received pre-RT methotrexate--eight
       also received thiotepa and procarbazine--followed by whole-brain RT. The
       patient treated at recurrence (who had been previously irradiated)
       received chemotherapy alone, including methotrexate, thiotepa, and
       procarbazine. RESULTS: All had enhancing lesions on MRI and five (50%)
       had a single lesion (seven [70%] had a ring-enhancing mass). No patient
       had a response to corticosteroids. Four of seven (57%) assessable
       patients had a partial or complete response to chemotherapy prior to RT.
       Six of seven (86%) assessable patients had a complete response at the
       end of treatment. Median survival was 3.5 months for all 10 patients and
       7 months for the eight patients who completed therapy. Two patients
       survived for 1 year or longer. Eight patients died--six from infection
       (two treatment-related), one from progressive dementia, and one from a
       gastrointestinal hemorrhage. CONCLUSION: AIDS-related PCNSL responds to
       chemotherapy and RT, but only a few patients benefit with prolonged
       survival.
