Patients with head and neck squamous cell carcinoma (HNSCC) who have no history of tobacco or significant alcohol use appear to be more likely to present with earlier disease and smaller initial T-stage, but have worse than expected outcomes.
The use of positron emission tomography (PET) is not sensitive enough to warrant routine use in post-curative chemoradiation therapy diagnosis of patients with node-positive head and neck cancer, according to researchers in the field.
