Abstract

Objectives This study compared the relative prognostic utility of the Gross Tumor Volume (GTV), maximum Standardized Uptake Value (SUVmax), and Metabolic Tumor Volume (MTV) in a uniform cohort of oropharyngeal squamous cell carcinoma (OPSCC) patients treated with platinum-based concurrent chemoradiation therapy (CCRT). Methods and materials One-hundred OPSCC with a pretreatment [18F] fluorodeoxyglucose (FDG) positron emission tomography-computed tomography (PET-CT) were treated with CCRT. Kaplan-Meier curves and Cox proportional hazard models were generated. Results When dichotomized by the median, a smaller MTV correlated with improved 5 year locoregional control (LRC) (98.0% versus 87.0%, p = 0.049), freedom from distant metastasis (FDM) (91.7% versus 65.0%, p = 0.005), progression-free survival (PFS) (80.3% versus 56.7%, p = 0.015), and overall survival (OS) (84.1% versus 57.8%, p = 0.008), whereas a smaller GTV correlated with improved PFS (80.3% versus 57.4%, p = 0.040) and OS (82.1% versus 60.1%, p = 0.025). SUVmax failed to correlate with any outcome. On multivariate analysis, when adjusted for GTV, T-stage, and N-stage a smaller MTV remained independently correlated with improved FDM, PFS, and OS. GTV failed to reach significance in the multivariate model. Conclusions A smaller MTV correlates with improved LRC, FDM, PFS, and OS in OPSCC patients undergoing platinum-based CCRT.
