Receiver operating characteristic curve predicting (a) depth of invasion (> 10 mm) in the primary tumor for metabolic tumor volume and total lesion glycolysis and (b) extranodal extension for nodal total lesion glycolysis. T-MTV = metabolic tumor volume of primary tumor, T-TLG = total lesion glycolysis of primary tumor, N-MTV = metabolic tumor volume of metastatic node, N-TLG = total lesion glycolysis of metastatic node
