Aim: To investigate whether 18F-fluorodeoxyglucose uptake is associated with overall survival in patients with major salivary gland cancer using univariate and multivariate analyses after adjusting for pathological stage (eighth edition of the International Union Against Cancer). Patients and Methods: A total of 32 patients with major salivary gland cancer treated with curative surgery were enrolled. Parameters for 18F-fluorodeoxyglucose uptake were assessed by positron-emission tomography combined with computed tomography. Results: Using univariate and multivariate analyses after adjusting for pathological stage, a maximum standardized uptake value ≥26, peak standardized uptake value ≥20.3, metabolic tumor volume ≥9.7, and total lesion glycolysis ≥263 were significantly correlated with shorter overall survival. Conclusion: Parameters of 18F-fluorodeoxyglucose uptake in major salivary gland cancer are predictive of overall survival after adjusting for the pathological stage.
