Abstract

Tonsillar carcinoma arises from the malignant transformation of the epithelial cells covering the tonsils or the connective tissues within the tonsil structure. Human papillomavirus (HPV) infection is associated with head and neck tumors, including tonsillar squamous cell carcinoma. Objectives: the prevalence of human papillomavirus (HPV) infection in patients with tonsillar squamous cell carcinoma at Hanoi Medical University Hospital. Subjects and Methods: A cross-sectional descriptive study was conducted on 42 paraffin-embedded tissue samples from patients diagnosed with tonsillar squamous cell carcinoma at Hanoi Medical University Hospital during 2022. Semi-nested PCR amplification of the L1 gene of HPV DNA, and the sequencing method was HPV genotyped. Results and Conclusion: The average age of the patients in our study was 54.97±9.64 years, with those aged over 60 comprising the highest proportion (38.1%). Male patients constituted the majority (88.1%). The rate of HPV positivity in tonsillar squamous cell carcinoma patients was 23.8%, including HPV16 and HPV18 with 90% and 10.0%, respectively.
