Use of extended HR-HPV Genotyping in improving the Triage Strategy of 2019 ASCCP recommendations in Women with positive HR-HPV diagnosis and Simultaneous LSIL Cytology Results.

J Cancer 2021 19;12(14):4332-4340. Epub 2021 May 19.

Department of Gynecology, Laboratory of Gynecologic Oncology, Fujian Maternity and Child Health Hospital, Affiliated Hospital of Fujian Medical University, Fuzhou 350001, Fujian, P.R. China.

According to the 2019 American Society for Colposcopy and Cervical Pathology (ASCCP) recommendations, women with a positive high-risk human papillomavirus (HR-HPV) diagnosis and low-grade cervical intraepithelial lesion (LSIL) cytology result should be referred for further colposcopy examination. However, this strategy results in over-treatment in several cases. In this study, we assessed the performance of extended HR-HPV genotyping in women with a simultaneous positive HR-HPV and LSIL diagnosis with the aim of improving the current triage strategy.

The impact of the CervicalCheck controversy on provision of colposcopy services in Ireland: A cohort study.

Eur J Obstet Gynecol Reprod Biol 2021 May 24;262:228-231. Epub 2021 May 24.

Department of Colposcopy, The National Maternity Hospital, Dublin, Ireland.

Objectives: In 2018, an inquiry into the Irish Cervical Cancer screening programme (CervicalCheck) was initiated, following publicised cases of non-disclosure regarding internal audit results of cytology screening in women diagnosed with cervical cancer. The inquiry attracted widespread media coverage and the government offered women free, out of programme screening. We investigated whether the controversy led to an increase in referrals based on clinical suspicion and the impact on waiting times for abnormal cytology. Read More

Cervical pap smears and pandemics: The effect of COVID-19 on screening uptake & opportunities to improve.

Hannah Masson

Womens Health (Lond) 2021 Jan-Dec;17:17455065211017070

School of Medicine, College of Medical, Veterinary and Life Sciences, University of Glasgow, UK.

Background: The Coronavirus disease 2019 (COVID-19) pandemic has led to an unprecedented upheaval within global healthcare systems and resulted in the temporary pausing of the National Health Service (NHS) Scotland Cervical Screening Programme. With several months of backlogs in appointments, there has not only been a reduction in primary samples being taken for human papilloma virus (HPV) testing but there have also been fewer women referred to colposcopy for investigation and treatment of precancerous or cancerous changes as a result. Encouraging uptake for cervical screening was always a priority before the pandemic, but it is even more important now, considering that the fears and barriers to screening that women may have are now exacerbated by COVID-19.

Impact of disruptions and recovery for established cervical screening programs across a range of high-income country program designs, using COVID-19 as an example: A modelled analysis.

Prev Med 2021 May 21:106623. Epub 2021 May 21.

Cancer Research Division, Cancer Council NSW, Sydney, Australia; School of Public Health, University of Sydney, Sydney, Australia. Electronic address:

COVID-19 has disrupted cervical screening in several countries, due to a range of policy-, health-service and participant-related factors. Using three well-established models of cervical cancer natural history adapted to simulate screening across four countries, we compared the impact of a range of standardised screening disruption scenarios in four countries that vary in their cervical cancer prevention programs. All scenarios assumed a 6- or 12-month disruption followed by a rapid catch-up of missed screens. Read More

Research Institute of Oncology (IPON)/Department of Gynecology and Obstetrics, Federal University of Triângulo Mineiro, Uberaba - MG, Brazil.

Studies have demonstrated that the size of lesion in colposcopic imaging can be associated with the grade of CIN. We evaluated 36 patients and at the time of colposcopy, the images were recorded and analysed for lesion area measurement. A ROC curve was used to obtain the area under the curve and to determine the best cut-off values between area lesion (pixels) and biopsy result. Read More

Department of Computer Science, School of Informatics and Electrical Engineering, Institute of Technology, Ambo University, Ambo, Post Box No. 19, Ethiopia.

Traditional screening of cervical cancer type classification majorly depends on the pathologist's experience, which also has less accuracy. Colposcopy is a critical component of cervical cancer prevention. In conjunction with precancer screening and treatment, colposcopy has played an essential role in lowering the incidence and mortality from cervical cancer over the last 50 years. Read More
