The spectrum of HIV-related lymphoid malignancies certainly includes non-Hodgkin's lymphoma (NHL; i.e., chiefly large-cell lymphoma and Burkitt's lymphoma), primary lymphoma of the brain (PBL) and, possibly, Hodgkin's disease (HD). Since the mid-1990s, several epidemiological studies have led to better quantification of the burden of lymphomas in HIV-infected populations. AIDS surveillance data from 17 western European countries show that between 1988 and 1997 a total of 7,148 AIDS cases had NHL as the AIDS- defining illness. The yearly number of cases rose steadily from 1988 to 1995 but declined thereafter. As a percentage of AIDS-defining illnesses, NHL increased from 3.6% in 1994 to 4.9% in 1997. Percent increases were observed in different strata by area, age group, sex and HIV-transmission group. To estimate relative risk (RR) of NHL and other lymphoid neoplasms in unselected HIV-seropositive populations, records of population-based cancer registries and AIDS registries were linked in the United States, Italy and Australia. RRs for NHL in adults with HIV/AIDS ranged between 14 (for low-grade NHL) to over 300 (for high-grade NHL). For HD, the RR was approximately 10. Limited findings from studies based on death certificates and cohorts of HIV- seropositive persons were consistent with those from registry linkage studies. In developing countries, the risk of HIV-associated NHL appears to be much lower than in developed countries, but under-ascertainment and earlier death from other AIDS manifestations may explain the lack of HIV- associated lymphomas in Africa.
