Correlation of T-cell immune response with spontaneous resolution and subsequent relapse of Hodgkin's lymphoma
2006
To our knowledge, there has been no report of spontaneous regression in a non-immunocompromised adult with classical Hodgkin's lymphoma (HL) in the absence of chemotherapy. We describe spontaneous regression and subsequent relapse of Epstein – Barr virus (EBV)-positive HL in an otherwise healthy male adult. The clinical course was associated with an increase in regulatory T-cell markers within the peripheral blood and diseased lymph node at the time of relapse and with a concomitant reduction in cellular immunity against relevant EBV latent membrane protein tumor-associated antigens. Our findings are in keeping with previous observations that implicate impaired cellular immunity in the immunopathogenesis of EBV-positive HL.
