Blood Epstein–Barr virus DNA does not predict outcome in advanced HIV-associated Hodgkin lymphoma

Abstract

In HIV-seronegative patients with advanced Hodgkin lymphoma (HL), Epstein–Barr virus (EBV) viraemia at diagnosis predicts a worse progression-free survival (PFS), independent of the International Prognostic Score. However, its role in HIV-associated HL is uncharacterised. We collected clinico-pathologic and treatment data from a prospective series of 44 HIV-associated HLs from 2000 to 2016. We evaluated circulating EBV DNA as a prognostic factor on uni- and multivariable analyses in relationship to the International Prognostic Index criteria. In 44 patients with HIV-associated HL, EBV was detected by in situ hybridisation in all diagnostic biopsies. Blood EBV DNA was detectable in 26 patients (59%) with a median of 600 copies/mL (range 0–161,000). EBV DNA was independent of CD4 cell count (p = 0.9) or HIV viral load (p = 0.6) and did not predict PFS (HR 1.6, 95% CI 0.39–6.7, p = 0.49). EBV DNA is not a prognostic trait in HIV-associated HL. Prognostication in HIV-associated HL should be solely based on the International Prognostic Index criteria.
