Whole-Body Positron Emission Tomography Using18F-Fluorodeoxyglucose for Posttreatment Evaluation in Hodgkin’s Disease and Non-Hodgkin’s Lymphoma Has Higher Diagnostic and Prognostic Value Than Classical Computed Tomography Scan Imaging
Abstract
A residual mass after treatment of lymphoma is a clinical challenge, because it may represent vital tumor as well as tissue fibrosis. Metabolic imaging by 18F-fluorodeoxyglucose (18F-FDG) positron emission tomography (PET) offers the advantage of functional tissue characterization that is largely independent of morphologic criteria. We compared18F-FDG PET to computed tomography (CT) in the posttreatment evaluation of 54 patients with Hodgkin’s disease (HD) or intermediate/high-grade non-Hodgkin’s lymphoma (NHL). Residual masses on CT were observed in 13 of 19 patients with HD and 11 of 35 patients with NHL. Five of 24 patients with residual masses on CT versus 1 of 30 patients without residual masses presented a positive18F-FDG PET study. Relapse occurred in all 6 patients (100%) with a positive 18F-FDG PET, 5 of 19 patients (26%) with residual masses on CT but negative 18F-FDG PET, and 3 of 29 patients (10%) with negative CT scan and18F-FDG PET studies (P ≤ .0001). We observed a higher relapse and death rate in patients with residual masses at CT compared with patients without residual masses at CT (progression-free survival at 1 year: 62 ± 10 v88 ± 7%, P = .0045; overall survival at 1 year: 77 ± 5 v 95 ± 5%, P = .0038). A positive18F-FDG PET study was even more consistently associated with poorer survival: compared with patients with a negative18F-FDG PET study, the 1-year progression-free survival was 0% versus 86% ± 5% (P < .0001) and the 1-year overall survival was 50% ± 20% versus 92% ± 4% (P < .0001). The detection of vital tumor by 18F-FDG PET after the end of treatment has a higher predictive value for relapse than classical CT scan imaging (positive predictive value: 100% v42%). This could help identify patients requiring intensification immediately after completion of chemotherapy. However,18F-FDG PET mainly predicts for early progression but cannot exclude the presence of minimal residual disease, possibly leading to a later relapse.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
