Background: Screening participation remains suboptimal in cervical cancer (CC) and colorectal cancer (CRC) screening despite their effectiveness in reducing cancer-related morbidity and mortality. We investigated the effectiveness of an intervention by leveraging the high participation rate in breast cancer (BC) screening as an opportunity to offer self-sampling kits to nonparticipants in CC and CRC screening.

Methods And Findings: A pragmatic, unblinded, cluster-randomised, multiple period, crossover trial was conducted in 5 BC screening units in the Central Denmark Region (CDR) between September 1, 2021 and May 25, 2022.

Introduction: In Denmark, where human papillomavirus (HPV) -based cervical cancer screening is being implemented, the aim of this pilot implementation study was to test a specific screening algorithm, assess follow-up examination attendance, and measure the proportion of precancer lesions found in relation to the number of women referred for colposcopy.

Material And Methods: From May 2017 to December 2020, 36 417 women in the uptake area of the Department of Pathology, Vejle Hospital, Region of Southern Denmark, were included in the HPV group. Women positive for HPV16/18 irrespective of cytology and women positive for other high-risk HPV (hrHPV) types having concomitant abnormal cytology were referred directly to colposcopy.

Article Synopsis
  • Colposcopy is crucial for detecting cervical precancerous lesions, especially in postmenopausal women, but challenges arise due to age-related cervical changes that could lead to missed diagnoses.
  • This study aims to determine if pre-treatment with vaginal estrogen improves colposcopy effectiveness by increasing the visibility of the transformation zone, involving 150 women over 50 with abnormal cervical screening results.
  • The study is ethically approved and will compare outcomes like the visibility of the transformation zone, detection rates of cervical lesions, and the side effects of estrogen treatment versus a placebo.

Importance: Active surveillance for cervical intraepithelial neoplasia grade 2 (CIN2) is being implemented in many high-income countries due to the association of excisional treatment with preterm birth. However, it is unknown whether active surveillance results in lower risk of preterm birth given that cervical dysplasia itself is associated with higher risk of preterm birth.

Objective: To compare the preterm birth risk between women with CIN2 undergoing active surveillance or immediate loop electrosurgical excision procedure (LEEP).

High-risk human papillomavirus (hrHPV) is the cause of virtually all cervical cancers, most vaginal and anal cancers, and some vulvar cancer cases. With HPV testing becoming the primary screening method for cervical cancer, understanding the link between cervical hrHPV infection and the risk of other anogenital cancers is crucial. We assessed the risk of vulvar, vaginal and anal cancer and precancer (VIN2+, VaIN2+ and AIN2+) in a prospective cohort study including 455,349 women who underwent cervical hrHPV testing in Denmark from 2005 to 2020.

Article Synopsis
  • The study assessed the long-term risk of cervical cancer in women aged 18-40 with untreated cervical intraepithelial neoplasia grade 2 (CIN2) compared to those who received immediate treatment (LLETZ).
  • It involved 27,524 women diagnosed from 1998 to 2020, finding that 104 developed cervical cancer during follow-up, with a higher incidence in the active surveillance group.
  • Results indicated that while the cervical cancer risk was similar between both groups initially, it significantly increased for the active surveillance group after two years, highlighting the need for close monitoring in these patients.

Background: Cervical intraepithelial neoplasia grade 2 has historically been the threshold for surgical excision, but because of high regression rates, many countries are transitioning to active surveillance. However, estimates for regression rates are based on small studies with heterogeneous definitions of regression and progression.

Objective: This study aimed to describe regression and progression rates of cervical intraepithelial neoplasia grade 2 using nationwide healthcare registry data.

Immunocompromised women are at increased risk of having HPV detected and developing HPV-related diseases such as genital warts, anogenital dysplasia, and cancer. This review aims to summarize the current literature regarding the immunogenicity of the HPV vaccine in immunocompromised women and to discuss whether HPV vaccination may be able to reduce the risk of cervical dysplasia and cancer. HPV vaccination induces an immune response in these women; however, it is unknown whether vaccination is effective in reducing the risk of cervical dysplasia and cancer.

Introduction: Many countries have adopted active surveillance in women with cervical intraepithelial neoplasia grade 2 (CIN2), leaving the lesion untreated. However, there is a lack of consensus on the eligibility criteria for active surveillance across countries, with some abstaining from active surveillance in women with human papilloma virus 16 (HPV16) or a high-grade cytology. Here, we aimed to describe the distribution of HPV genotypes, age, and cytology in women undergoing active surveillance for CIN2.

Background: High-risk human papillomavirus (HPV) test is replacing cytology as the primary cervical cancer screening test due to superior sensitivity, but in most countries women ≥65 years have never had an HPV test despite they account for around 50% of cervical cancer deaths. We explored the effect of a catch-up HPV test among 65- to 69-year-old women without previous record of HPV-based screening.

Methods And Findings: This population-based nonrandomized intervention study (quasi-experimental design) included Danish women aged 65 to 69 with no record of cervical cancer screening in the last ≥5.
