Abstract
Introduction
Recurrent cervical intraepithelial lesions (rCIN2/3) after treatment of CIN2/3 occur in 5–15% of cases. rCIN2/3 can result from incomplete resection of CIN2/3, where the same HPV type and variant remains present. rCIN2/3 could also occur following a new infection with a different HPV variant of the same HPV type as the initial lesion. This study investigates HPV16 consensus variants in paired HPV16 positive scrapes from baseline CIN2/3 and rCIN2/3 lesions.
Methods
Paired HPV16 positive cervical scrapes of women with CIN2/3 at baseline and rCIN2/3 6 or 12 months after treatment were selected for whole-genome amplification and Illumina sequencing. Sequences were compared and nucleotide changes over time were characterized.
Results
From 14 paired samples, 10 had identical consensus variants in baseline CIN2/3 and rCIN2/3. Four paired samples showed one to three nucleotide variations at recurrent disease compared to baseline.
Conclusion
Identical or nearly identical HPV16 consensus variants were found in scrapes of paired HPV16 positive baseline CIN2/3 and rCIN2/3 lesions after treatment, suggesting no need for HPV variant analysis when the same HPV type is found in both lesions. These results argue for either incomplete excision of baseline CIN2/3 or inability of clearance of the original HPV infection.
期刊介绍:
The official Journal of the International Papillomavirus Society Papillomavirus Research (PVR), the Journal of HPV and other Small DNA Tumor Viruses publishes innovative papers related to all aspects of papillomaviruses and other small DNA tumor viruses. The official journal of the International Papillomavirus Society, PVR is an open access publication that aims to bring together virologists, immunologists, epidemiologists and clinicians working in the booming field of HPV and animal papillomaviruses, polyomaviruses and other small DNA tumor viruses and their associated diseases, in order to foster and facilitate interdisciplinary communication. The journal welcomes original research articles, reviews, short communications, opinion articles and regional update reports on papillomaviruses and other tumor viruses in the following sections: a. Biology of papillomaviruses and related viruses from life cycle to cancer b. Epidemiology etiology and natural history studies c. Natural and induced immunity including vaccine research d. Intervention studies and strategies including i. Clinical studies and trials ii. HPV treatments iii. HPV vaccination programs iv. Diagnostics and screening e. Infection and disease prevention, modeling studies f. Guidelines and public health recommendations g. HPV Studies in special populations Regional and local studies on these viruses.
