Prospective Trial Incorporating Pre-/Mid-Treatment [18F]-Misonidazole Positron Emission Tomography for Head-and-Neck Cancer Patients Undergoing Concurrent Chemoradiotherapy

Excellent locoregional control was observed in this series of head-and-neck cancer patients treated with concurrent platinum-based chemotherapy and intensity-modulated radiotherapy despite evidence of detectable hypoxia on the pretreatment 18F-FMISO PET/computed tomography scans of 18 of 20 patients. In this prospective study, neither the presence nor the absence of hypoxia, as defined by positive 18F-FMISO findings on the mid-treatment PET scan, correlated with patient outcome. The results of this study have confirmed similar results reported previously.
