Additionally, the clinical significance of the semiquantitative analysis of the standardized uptake value (SUV), its predictive role in the follow\u2010up setting, and its value in detection of synchronous primaries were studied.<\/jats:p><\/jats:sec><jats:sec><jats:title>Study Design:<\/jats:title><jats:p>Retrospective chart review.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods:<\/jats:title><jats:p>Twenty\u2010six patients with a primary extranodal head and neck lymphoma (22 diffuse large B\u2010cell lymphoma, one Hodgkin's lymphoma, three malignant T\u2010cell lymphomas) were included. We retrospectively evaluated the clinical outcomes according to the maximum standardized uptake values of the primary lesion (SUV<jats:sub>max<\/jats:sub>) and whether a positron emission tomography\/computed tomography (PET\/CT) was performed or not in the follow\u2010up studies. The median SUV<jats:sub>max<\/jats:sub> was chosen as the cutoff value. The patients were then grouped as those with either low or high SUV<jats:sub>max<\/jats:sub>, respective to the cutoff value. Event\u2010free survival and cumulative survival were endpoints of interest.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results:<\/jats:title><jats:p>Nineteen patients (73%) were above the age of 60 years; the median age was 70 years (range, 28\u201387 years). Most primary sites were in the Waldeyer's ring (15 patients, 60%), whereas in four patients (27%) only the palatine tonsil was affected. The SUV<jats:sub>max<\/jats:sub> ranged from 5.8 to 33.9. In one patient, relevant fluorodeoxyglucose (FDG) uptake within the intestine revealed a cecal adenocarcinoma as a secondary primary. Twenty of the 25 clinically followed patients (80%) achieved complete remission after treatment. Patients with high SUV<jats:sub>max<\/jats:sub> showed favorable survival (log\u2010rank test, <jats:italic>P<\/jats:italic> = .044). A tendency for longer survival within the group with follow\u2010up PET\/CT studies could be noted but with no significant statistical difference (<jats:italic>P<\/jats:italic> = .349).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions:<\/jats:title><jats:p><jats:sup>18<\/jats:sup>F\u2010FDG\u2010PET\/CT imaging is a potent primary staging tool. It also has application as an instrument for evaluation of follow\u2010up and response to therapy in patients suffering from primary extranodal lymphoma and for detection of secondary malignancies. Furthermore, <jats:sup>18<\/jats:sup>F\u2010FDG uptake by the primary lesion may be related to better survival.
