Diagnostic modalities for distant metastasis in head and neck squamous cell carcinoma: Are we changing life expectancy?

Abstract

Although a PET scan is more likely to diagnose multiple DM sites, there was no difference in life expectancy based on imaging modality. Patients who are symptomatic from their distant metastasis have a worse life expectancy, and palliative chemotherapy was able to increase life expectancy, even in patients who were symptomatic from the distant metastasis.
