Fig. 2

CONSORT flow of study population: Therapeutic responses in 82 patients with HNSCC were retropsectively analyzed via baseline and post CRT PET/CT images. Six of 22 patients registering postSUVmax ≥4.4 underwent salvage surgery, compared with one of 60 patients at postSUVmax <4.4. Distribution of patients experiencing iLRS is shown below by postSUVmax cutpoint (≥4.4 vs <4.4). Abbreviations: HNSCC, head & neck squamous cell carcinoma; CRT, chemoradiotherapy; PET/CT, positron emission tomography/computed tomography; postSUVmax, maximum standardized uptake value in PET/CT after definitive CRT; iLRSF, immediate locoregional and/or systemic failure
