Relapse-free survival curve showing MTV for each threshold. SUVmax, maximal standardized uptake value; MTV, metabolic tumor volume; TLG, total lesion glycolysis; TUR, tumor-to-liver uptake ratio; SUL, SUV normalized to lean body mass; ROC: receiver operating characteristic curve. Relapse-free survival curves of the patients were divided by values below and above the cut-off value obtained using ROC analysis. For all the parameters for MTV, particularly the SUVmax of 3.5 (MTV 3.5, and TLR of 2 (MTV-TLR2), the values above the cut-off value were more frequently associated with recurrence than the values below the cut-off value
