Hodgkin disease developing in patients infected by human immunodeficiency virus results in clinical features and a prognosis similar to those in patients with human immunodeficiency virus-related non-Hodgkin lymphoma

Background: Unlike aggressive non-Hodgkin lymphoma (NHL), Hodgkin disease (HD) develops rarely in patients who are infected by human immunodeficiency virus (HIV), and its characteristics are not well defined. The authors analyzed the clinicopathologic and prognostic features from a consecutive series of patients with HIV-associated HD who were observed at their institution and compared them with the features observed in a concurrent series of patients with systemic HIV-related NHL.

Methods: Eighteen patients with HIV infection who were diagnosed and treated uniformly from 1985 to 1999 at a single primary referral center were analyzed. Their demographic, immunologic, and clinicopathologic features; responses to treatment; and outcomes were compared with those of 98 patients with systemic NHL of aggressive histology who were diagnosed during the same period and with 165 HIV negative patients with HD.

Results: HIV-associated HD and NHL occurred in patients with similar age, gender, HIV risk factors, degree of immunodeficiency, and incidence of previous acquired immunodeficiency syndrome. The clinical presentation of HIV-associated HD was atypical and was more aggressive than in HIV negative patients (mediastinal involvement, 11%; Stage III-IV, 84%; B symptoms, 83%). It was similar to HIV-related NHL, except for the frequency of extralymph node disease, which was seen less frequently in patients who had HD (56%) compared with patients who had NHL (82%; P = 0.025), and the frequency of bone marrow involvement, which was unexpectedly higher in patients who had HD (50%) compared with patients who had NHL (20%; P = 0.011). Potentially curative treatment was administered to 77% of patients with HD and 66% of patients with NHL. Complete remission and disease recurrence rates as well as disease free and overall survival rates did not differ significantly, with estimated overall survival at 5 years of 24% in patients with HD and 23% in patients with NHL.

Conclusions: HIV-associated HD is an aggressive disease with demographic, clinical, and prognostic features nearly identical to those of HIV-related NHL.
