HIV infection is considered a major risk factor for primary central nervous system lymphoma (PCNSL). However, the percentage of PCNSL that occurs in HIV + patients is not well defined. We aimed to assess the prevalence of HIV infection in patients with PCNSL through a systematic review and meta-analysis. Electronic databases were searched for studies assessing the presence of HIV infection in series of patients with PCNSL. Pooled prevalence of HIV infection in PCNSL was calculated, with a subgroup analysis based on the geographic area. Twenty-seven studies with 6422 patients were included. Overall, pooled prevalence of HIV infection among PCNSL patients was 6.1 % with high heterogeneity. In the subgroup analysis, pooled prevalence was 3.6 % in India with low heterogeneity, 30.2 % (overall) and 16.5 % (after 2000) in the USA with high heterogeneity, 5.7 % in Europe with high heterogeneity, 2.2 % in East Asia with null heterogeneity, 7.3 % in South America with moderate heterogeneity. In conclusion, only a minor part of PCNSL occurs in patients with HIV. The results stratified by geographic area reflect the different prevalence of HIV infection in the general population, except for India, probably due to the shorter life expectancy of HIV + patients.

Abstract

HIV infection is considered a major risk factor for primary central nervous system lymphoma (PCNSL). However, the percentage of PCNSL that occurs in HIV + patients is not well defined. We aimed to assess the prevalence of HIV infection in patients with PCNSL through a systematic review and meta-analysis. Electronic databases were searched for studies assessing the presence of HIV infection in series of patients with PCNSL. Pooled prevalence of HIV infection in PCNSL was calculated, with a subgroup analysis based on the geographic area. Twenty-seven studies with 6422 patients were included. Overall, pooled prevalence of HIV infection among PCNSL patients was 6.1 % with high heterogeneity. In the subgroup analysis, pooled prevalence was 3.6 % in India with low heterogeneity, 30.2 % (overall) and 16.5 % (after 2000) in the USA with high heterogeneity, 5.7 % in Europe with high heterogeneity, 2.2 % in East Asia with null heterogeneity, 7.3 % in South America with moderate heterogeneity. In conclusion, only a minor part of PCNSL occurs in patients with HIV. The results stratified by geographic area reflect the different prevalence of HIV infection in the general population, except for India, probably due to the shorter life expectancy of HIV + patients.
