¹⁸ F‐FDG‐PET/CT versus panendoscopy for the detection of synchronous second primary tumors in patients with head and neck squamous cell carcinoma

Abstract

(18)F-FDG-PET/CT is superior to panendoscopy. With a negative (18)F-FDG-PET/CT, the extent of endoscopy can be reduced to the area of the primary tumor. Due to the costs, (18)F-FDG-PET/CT is recommended only in advanced disease to assess potential distant disease. In early-stage cancer, panendoscopy is accurate enough to rule out secondary tumors.
