Abstract
Negative FDG PET after treatment of Hodgkins lymphoma predicts favorable prognosis but positive predictive value of PET varies in different studies to a great extent. The aim of this retrospective study was to assess the PET findings in lungs in 24 patients with initial pulmonary involvement of Hodgkin's lymphoma after initial treatment and during the follow-up. 46 PET studies were evaluated in a group of 24 patients. 1/6 patients with initial pulmonary infiltration of Hodgkin's lymphoma had PET positive pulmonary findings after therapy, but without tumor infiltration.
The prognostic significance of positive PET findings after initial treatment of Hodgkin's lymphoma remains to be established. Repeated PET examinations during the follow-up are suggested in these patients and lung biopsy should be considered in selected cases.
