PET Followup after remission in Hodgkin’s – pro
The strategy of detecting relapse after completed treatment with the use of PET in surveillance in the absence of symptoms suggestive of recurrence and the results of published studies are rather discouraging because of low positive predictive value. The results of previous studies have not confirmed the significance of PET in this indication and they are discouraged because of low positive predictive value. The false-positive rate with PET scans exceeding 20% and can lead to unnecessary further diagnostic procedures, exposure to ionizing radiation, patients’ anxiety and generates additional costs. Experts recommend performing PET only in case of clinical suspicion of relapse.
NCCN recommends CT scans with contrast at 6,12,24 months and PET only if the prior PET had Deauvilal score of 4-5.
