Description
Summary:Introduction Growing evidence shows a causal role of high-risk humane papillomavirus (HPV) infections in the development of head and neck cancer. A recent case report shows two patients suffering from tonsillar cancer without any risk factors apart from their work as gynecologists doing laser ablations and loop electrosurgical excision procedures (LEEP). The aim of the present investigation is to evaluate whether surgical plume resulting from routine LEEPs of HSIL of the cervix uteri might be contaminated with the DNA of high-risk HPV. Materials and methods The prospective pilot study is done at the Department of Gynecology and Obstetrics of the University of Lübeck, Germany. The primary outcome was defined as HPV subtype in resected cone and in surgical plume resulting from LEEPs of HSIL of the cervix uteri. Plume resulting from LEEPs was analyzed using a Whatman FTA Elute Indicating Card which was placed in the tube of an exhaust suction device used to remove the resulting aerosols. For detection of HPV and analysis of its subtype, the novel EUROArray HPV test was performed. Resected cones of LEEPs were evaluated separately for HPV subtypes. Results Four samples of surgical plume resulting from routine LEEPs indicated contamination with high-risk HPV and showed the same HPV subtype as identified in the resected cones. Conclusion Surgical plume resulting from routine LEEPs for HSIL of the cervix uteri has the risk of contamination with high-risk HPV. Further investigations of infectiousness of surgical plume are necessary for evaluation of potential hazards to involved healthcare professionals.
