Initial Staging of Squamous Cell Carcinoma of the Oral Cavity, Larynx and Pharynx (Excluding Nasopharynx) Part 2: Remote Extension Assessment and Exploration for Secondary Synchronous Locations Outside of the Upper Aerodigestive Tract

This clinical practice guideline is part 2 of a 3 part series on the initial staging of squamous cell carcinoma of the oral cavity, larynx and pharynx (excluding nasopharynx). The guideline discusses remote extension assessment (exploration for remote metastasis) and exploration for secondary synchronous locations outside of the upper aero digestive tract. Outcomes of interest include metastatic risk, prognostic factors, and sensitivity and specificity of imaging techniques.
