Efficacy of fine‐needle aspiration in diagnosing cervical nodal metastasis from nasopharyngeal carcinoma after radiotherapy

Abstract

Diagnostic efficacy of FNA for residual or recurrent cervical lymph node metastasis in NPC is significantly reduced after previous RT. To ensure that the proper diagnosis is made early, triple assessment using FNA, pEBV-DNA, and MRI should be adopted in this scenario.
