Abstract

Primary central nervous system lymphoma (PCNSL) related to acquired immunodeficiency syndrome (AIDS) is a lethal disorder, but the recent application of highly active antiretroviral therapy (HAART) has significantly improved prognosis. This retrospective cohort study of AIDS-related PCNSL examined the actual clinical outcomes and prognostic variables affecting overall survival (OS) in the HAART era. Twenty-three newly diagnosed AIDS-related PCNSL at 12 regional centre hospitals for HIV/AIDS in Japan between 2002 and 2008 were consecutively enrolled. The estimated 3-yr OS rate of the entire cohort was 64% (95%CI, 41.0–80.3%). Whole brain radiation therapy (WBRT) had an independent positive impact on survival (WBRT ≥30 Gy vs. others, P = 0.02). Nine of 10 patients with a good performance status (PS) (0–2) remained alive with complete response, whereas 10 (77%) of 13 of those with a poor PS (3–4) died mostly after a short period. The estimated 3-yr OS rate of the groups with a good and poor PS was 100% and 38% (95%CI, 14–63%), respectively (P = 0.01). Leukoencephalopathy (grade ≥ 2) developed in 21% of those that survived more than 12 months after radiation. The patients receiving a curative intent radiation dose (≥30 Gy) of WBRT achieved prolonged survival while maintaining a good quality of life in the HAART era, especially among patients with a favourable PS.
