Background: Accumulating evidence suggests that cutaneous viral infections are risk factors for the development of keratinocyte carcinomas. The Viruses in Skin Cancer (VIRUSCAN) Study, a prospective cohort study, was established in 2014 to investigate the risk of keratinocyte carcinoma associated with cutaneous human papillomavirus and polyomavirus infection and the possible interaction with ultraviolet radiation exposure (UVR).

Methods/results: VIRUSCAN incorporates repeated measures of viral infection using multiple markers of infection and quantitative measures of UVR using a spectrophotometer.

UV radiation (UVR) causing DNA damage is a well-documented risk factor for nonmelanoma skin cancer. Although poorly understood, UVR may also indirectly contribute to carcinogenesis by promoting immune evasion. To our knowledge, we report the first epidemiological study designed to investigate the association between quantitative measures of UVR, obtained using a spectrophotometer, and circulating T regulatory (Treg) cells.

Background: Findings from previous studies of cutaneous human papillomavirus (cuHPV) infection and keratinocyte carcinomas have varied due to several factors, including use of different sample types for cuHPV DNA detection. Elucidating the relationship between cuHPV infection in eyebrow hairs (EBHs) and skin swabs (SSWs) is critical for advancing the design of future studies.

Methods: DNA corresponding to 46 β-HPV and 52 γ-HPV types was measured in EBHs and SSWs obtained from 370 individuals undergoing routine skin cancer screening examinations.
