Diagnostic potential of 1-step nucleic acid amplification assay in patients with head and neck squamous cell carcinoma based on CK19 expression in a primary lesion
The purpose of this study was to investigate the effects of CK19 expression in the primary lesions of head and neck squamous cell carcinoma on the diagnosis of the cervical lymph node (CLN) metastasis using the 1-step nucleic acid amplification assay.
