Central nervous system involvement in AIDS-related lymphomas.
Ontology highlight
ABSTRACT: Central nervous system (CNS) involvement is reportedly more common in acquired immunodeficiency syndrome (AIDS)-related lymphomas (ARL). We describe factors and outcomes associated with CNS involvement at baseline (CNS(B) ) and relapse (CNS(R) ) in 886 patients with newly diagnosed ARL. Of 886 patients, 800 received either intrathecal (IT) therapy for CNS(B) or IT prophylaxis. CNS(B) was found in 13%. CNS(B) was not associated with reduced overall survival (OS). There was no difference in the prevalence of CNS(B) between the pre-combination antiretroviral therapy (cART) and cART eras. 5·3% of patients experienced CNS(R) at a median of 4·2 months after diagnosis (12% if CNS(B) ; 4% if not). Median OS after CNS(R) was 1·6 months. On multivariate analysis, only CNS(B) [hazard ratio (HR) 3·68, P = 0·005] and complete response to initial therapy (HR 0·14, P < 0·0001) were significantly associated with CNS(R) . When restricted to patients without CNS(B) , IT CNS prophylaxis with 3 vs. 1 agent did not significantly impact the risk of CNS(R) . Despite IT CNS prophylaxis, 5% of patients experienced CNS(R) . Our data confirms that CNS(R) in ARL occurs early and has a poor outcome. Complete response to initial therapy was associated with a reduced frequency of CNS(R) . Although CNS(B) conferred an increased risk for CNS(R) , it did not impact OS.
