Abstract

<abstract abstract-type="main"> <title> <x xml:space="preserve">Abstract</x> </title> <p>Cutaneous human papillomaviruses (HPV) have been reported in cutaneous squamous cell carcinoma (SCC). We conducted a clinic‐based case–control study to investigate the association between genus‐beta HPV DNA in eyebrow hairs (EBH) and SCC. EBH from 168 SCC cases and 290 controls were genotyped for genus‐beta HPV DNA. SCC tumors from a subset of cases (<italic>n</italic> = 142) were also genotyped. Viral load was determined in a subset of specimens positive for a single HPV type. Associations with SCC were estimated by odds ratios (OR) and 95% confidence intervals (CI) adjusted for age and sex using logistic regression. Statistical tests were two‐sided. EBH DNA prevalence was greater in cases (87%) than controls (73%) (<italic>p</italic> < 0.05), and the association with SCC increased with the number of HPV types present, (≥4 types <italic>vs</italic>. HPV‐negative: OR = 2.02, 95% CI = 1.07–3.80; <italic>p</italic><sub>trend</sub> = 0.02). Type‐specific associations were observed between SCC and DNA in EBH for HPV23 (OR = 1.90, 95% CI = 1.10–3.30) and HPV38 (OR = 1.84, 95% CI = 1.04–3.24). Additionally, when compared with the controls, the DNA prevalence in EBH was significantly higher among cases for 11 of the 25 genus‐beta types tested, when accounting for DNA for the same HPV type in the tumor (ORs = 3.44–76.50). Compared to controls, the mean viral DNA load in EBH among the selected cases was greater for HPV5, HPV8 and HPV24, but lower for HPV38. SCC cases were more likely than controls to have HPV DNA+ EBH for single and multiple HPV types, providing additional support for the potential role of genus‐beta HPV infections in SCC development.</p> </abstract>
