Implication

Randomized trial explores HPV integration's role in tumor development in head and neck squamous cell carcinomas, suggesting a unique pathway for tumorigenesis.

Key Points

To assess the integration of HPV 16/18 DNA in head and neck squamous cell carcinomas and their mutation status in the p53 gene.
Analyzed 47 cases of HNSCC for HPV 16/18 integration using fluorescence in situ hybridization (FISH).
Investigated p53 mutation status through immunohistochemistry and single-strand conformation polymorphism (SSCP) in exons 5-8.
Studied archival biopsy material from both premalignant lesions and malignant tumors.
21% of HNSCC exhibited HPV 16 integration, with 67% in tonsillar carcinomas.
p53 accumulation was present in 64% of HNSCC cases, including 80% of HPV-positive tumors, but no mutations were found in p53 exons 5-8.
An inverse relation was noted between tobacco use and HPV positivity in tumors.
