Screening for Distant Metastases in Patients With Head and Neck Cancer

Abstract

Screening in patients with three or more lymph node metastases, bilateral lymph node metastases, lymph nodes of 6 cm or larger, low jugular lymph node metastases, locoregional tumor recurrence, and second primary tumors revealed distant metastases in 10% or more. CT scan of the thorax is currently the single most important diagnostic technique for screening of distant metastases.
