Hematologic and immunologic status in Hodgkin's disease 5 years after radical radiotherapy.

The hematologic and immunologic status was evaluated after 5 years of continuously disease-free survival for 71 consecutive patients treated for Hodgkin's disease by radiotherapy. There was no evidence of residual hematologic depression, even in those patients treated initially with total nodal irradiation. Similarly, quantitative immunoglobulin levels were within the normal range, and the response to delayed hypersensitivity skin testing was intact in nearly all patients. These immunologic studies were consistent with the observed absence of an unusual incidence of infectious complications in these long-term survivors.
