Evolution of HIV-associated lymphoma over 3 decades

Introduction: The emergence of combined antiretroviral therapy (cART) and improvements in the management of opportunistic infections have altered the HIV epidemic over the last 30 years. We aimed to assess changes to the biology and outcomes of HIVassociated lymphomas over this period at the national center for HIV oncology in the United Kingdom. Methods: Clinical characteristics at lymphoma diagnosis have been prospectively collected since 1986, along with details of lymphoma treatment and outcomes. The clinical features and outcomes were compared between 3 decades: pre-cART decade (1986-1995), earlycART decade (1996-2005), and late-cART decade (2006-2015). Results: A total of 615 patients with HIV-associated lymphoma were included in the study: 158 patients in the pre-cART era, 200 patients in the early-cART era, and 257 patients in the late-cART era. In more recent decades, patients were older (P , 0.0001) and had higher CD4 cell counts (P , 0.0001) at lymphoma diagnosis. Over time, there has also been a shift in lymphoma histological subtypes, with an increase in lymphoma subtypes associated with moderate immunosuppression. The overall survival for patients with HIV-associated lymphoma has dramatically improved over the 3 decades (P , 0.0001). Conclusion: Over the last 30 years, the clinical demographic of HIV-associated lymphomas has evolved, and the outcomes have improved.
