Do hyperglycemia and diabetes affect the incidence of false-negative 18F-FDG PET/CT studies in patients evaluated for infection or inflammation and cancer?
High glucose levels at the time of the study but not DM may reduce the sensitivity of (18)F-FDG PET/CT in the assessment of malignancy. No significant impact on the FN rate was found in patients with infection and inflammatory processes with either DM or hyperglycemia.
Grade and stage are significant predictors of overall and disease-free survival for patients with OSCC. In this study, however, there was no survival difference between patients with tongue cancer and cancers located at other sites in the oral cavity.
