Univariate Cox hazards regression analysis of SUVmax as a dichotomous variable shows significance for progression-free and overall survivals. As a continuous variable, SUVmax significantly predicts for local control, progression-free and overall survivals. In multivariate Cox analysis, SUVmax remains a significant predictor of progression-free survival.
