Background:
In light of the steadily improving capability to treat opportunistic infections, the authors reviewed their recent experience with short course empiric radiotherapy for the treatment of human immunodeficiency virus (HIV)-associated presumed central nervous system (CNS) lymphoma.
Methods:
Medical records were reviewed of 32 previously unreported HIV-infected patients who had computed tomography and/or magnetic resonance imaging findings consistent with lymphoma, whose lesions had failed to respond to antitoxoplasmosis therapy and therefore subsequently treated with empiric radiotherapy to the cranium and meninges, nearly always 3000 cGy in 10 fractions.
Results:
The majority of patients were in poor general condition (median Karnofsky score = 50) when radiotherapy was initiated. Fifty percent improved during or after radiation. Median survival was 2.1 months.
Conclusions:
Despite progress made in the past several years in the treatment of opportunistic infections and brief clinical response to radiotherapy, patients with acquired immunodeficiency syndrome who have a presumed diagnosis of CNS lymphoma continue to have extremely poor survival. Early biopsy in patients with lesions that fail to respond to empiric antitoxoplasmosis treatment or with lesions radiographically most consistent with lymphoma may improve outcome.
