The management of primary central nervous system lymphoma related to AIDS in the HAART era

PURPOSE OF REVIEW: The review highlights the recent advances in the pathogenesis, diagnosis and treatment of AIDS-related primary CNS lymphoma (AIDS-PCNSL). RECENT FINDINGS: The incidence of AIDS-PCNSL has decreased in the era of highly active antiretroviral therapy (HAART). The prognosis has improved and this most probably in relation both with the HAART-induced immunologic status recovery and subsequently the possibility to use more aggressive treatment strategies. Immunomodulatory effect of HAART seems also to have an indirect antitumor activity on the disease. SUMMARY: The treatment strategy for AIDS-PCNSL in the HAART era tends to become similar to that of the immunocompetent population. In the absence of randomized trials devoted to AIDS-PCNSL, most current national comprehensive cancer network guidelines recommend the use of high-dose methotrexate-based chemotherapy combined or not with whole-brain radiotherapy as initial treatment in addition to HAART. The objective for the future would be that prognosis of AIDS-PCNSL catch up with that of the immunocompetent patients with special attention to systemic and neurocognitive tolerance of the treatments.
