Objectives

Narrative objectives1

To identify HPV-related precancerous lesions and early-stage cancer, collectively defined as HPV-related early tonsillar lesions, in resected tonsils from patients undergoing tonsillectomy for benign diseases, and to determine the diagnostic performance of high-risk HPV E6/E7 mRNA in preoperative gargle samples by comparing the assay results with the presence or absence of HPV-related early tonsillar lesions.
