Abstract
OBJECTIVE
To describe lymphoma in HIV-2-infected patients and compare their characteristics with lymphoma in HIV-1-infected patients.
DESIGN
Ancillary analysis from a single center prospective cohort of HIV-lymphoma.
METHODS
We report on 16 patients with HIV-2-lymphoma diagnosed after 1996 and included in a prospective cohort of HIV lymphoma. Five additional HIV-2-infected patients coinfected with HIV-1 or/and HTLV-I (6 lymphomas) are separately reported. The incidence of lymphoma in HIV-2-infected patients was evaluated in the French multicentric HIV-2 cohort.
RESULTS
Incidence of lymphoma in the French HIV-2 cohort was estimated as 0.6/1000 patient-years. In our series, the median CD4+ cell count was 166 × 106/l at the time of lymphoma diagnosis and 50% of patients had undetectable plasma HIV-2-RNA. Lymphomas were non-Hodgkin lymphoma (n = 12) and classical Hodgkin lymphoma (n = 4). Similarly to HIV-1-lymphoma, clinical presentation was aggressive in most cases. All but one patient received intensive chemotherapy. Complete remission was achieved in 13 cases and 1 patient relapsed. The overall survival was not statistically different from that observed in patients with HIV-1 lymphoma. The six additional lymphomas observed in five HIV-2-infected patients coinfected with HIV-1 or/and HTLV-I presented with similar clinical presentation but worse prognosis.
CONCLUSION
Despite the lower pathogenicity of HIV-2, the risk of developing lymphoma seems to be close to that observed in HIV-1 population with similar lymphoma characteristics. Compared with HIV-1, HIV-2-infected patients developed lymphoma later in their life but at a similar CD4+ cell count level.
