title: Association between human papillomavirus infection and laryngeal squamous cell carcinoma.
abstract: The aim of this study was to compare the prevalence of human papillomavirus (HPV) infection in laryngeal squamous cell carcinoma using two methods: PCR-DNA enzyme immunoassay (PCR/DEIA) and immunohistochemistry (IHC) for detection of HPV in specimens of laryngeal squamous cell carcinoma and to correlate the presence of HPV with the epidemiological and clinicopathological features of recurrence and survival. HPV DNA was amplified from 93 paraffin-embedded laryngeal squamous cell carcinoma tissue specimens by the short PCR fragment (SPF 10) primer set using PCR/DNA method. HPV detection using monoclonal anti-human papilloma virus antibodies Clone K1H8 for IHC reaction was performed on 130 specimens. HPV was identified in 35.5% of patients with laryngeal squamous cell carcinoma using PCR/DEIA and 27.7% using IHC. There was no statistically significant association between the presence of HPV and the epidemiological and clinicopathological features and recurrence. There was no statistically significant association between the presence of HPV and overall survival nor disease specific survival. Statistically significant correlation between HPV detection using PCR/DEIA technique and IHC technique was found. The presence of HPV infection in 27.7% and 38.9% of the patients suggests a possible role in the etiology of laryngeal squamous cell carcinoma. The SPF(10) PCR/DEIA technique is the most accurate method for detection of HPV in laryngeal squamous cell carcinoma.
