8.1. Initial Staging
- Patients with multistation or lower neck nodal involvement or high-grade tumor histology.
- To determine the surgical approach to the contralateral neck in tumors approaching the midline, to identify involved lymph nodes.
- For patients with locoregionally advanced cancer (e.g., T3–T4 primary or ≥N1 nodal staging), FDG PET/CT is preferred to evaluate for distant disease and thoracic metastases. In lieu of FDG PET/CT, CT of the chest with contrast is suggested to assess for presence of lung metastases and mediastinal nodal involvement.
- Detection of occult primary lesions in patients presenting with large nodal metastatic masses without identifiable primary cancer on conventional imaging (CT/MRI) before EUA, biopsies, and tonsillectomy.
