Abstract
The objective of this study is to establish the utilization trends of CT, MRI, and FDG-PET/CT for evaluation of oropharyngeal squamous cell carcinoma (OPSCC) patients. A total of 173 patients with newly diagnosed stage III or IV OPSCC between 2003 and 2009 were included. Frequency of imaging modality use, divided into four time periods (2003-04, 2005-06, 2007-08 and 2009), was evaluated. For initial staging, percentage of PET/CT use was 64.6%, 87.5%, 94.1% and 96.3%, with an increasing trend (p < 0.001). The CT (p = 0.762) and MRI (p = 0.224) use demonstrated no change in trend. For post-treatment imaging, percentage of PET/CT use was 59.5%, 68.6%, 89.7% and 100%, with an increasing trend (p < 0.001). The CT use demonstrated a decreasing trend (p = 0.004) and MRI showed no trend change (p = 0.231). PET/CT is used with an increasing trend for initial staging and has become a central imaging modality for follow up evaluation after treatment, for advanced OPSCC.Entities:
