Routine staging includes physical examination, chest X-ray, head and neck endoscopy, and head and neck CT scan or MRI. A thoracic CT scan may be carried out to rule out metastatic disease. Squamous cell head and neck cancer should be staged according to the TNM system and grouped into the following categories (Table). T4 tumors are subdivided into T4a resectable and T4b unresectable. Stage IV i...
