Cervical cancer (CC) is one of the most common gynecological malignancies with poor prognosis for advanced CC patients. LRRC8A is a volume-regulated anion channel protein involved in cellular homeostasis, but its role in CC remains largely unknown. In this study, we found that LRRC8A is elevated in CC and associated with poor prognosis. LRRC8A maintains cell survivals under the hypotonic condition, and promotes tumorigenesis through apoptosis suppression and . Notably, LRRC8A is upregulated by NSUN2-mediated mC modification. mC modified-LRRC8A mRNA is bound by the RNA binding protein YBX1 followed by the increased RNA stability. Moreover, loss of NSUN2 suppresses the proliferation and metastasis of CC cells, and NSUN2 expression is positively correlated with LRRC8A expression in CC. Altogether, our study demonstrates that the NSUN2-mC-LRRC8A axis is crucial and would be a potential therapeutic target for CC.

Objective: This study aimed to uncover the patterns of Human papillomavirus (HPV) infection outcomes in women and assess the risk factors that may affect these outcomes.
Methods: A retrospective study was conducted on 608 women who tested positive for HPV-DNA during their initial visit to the outpatient department of Shenzhen Longgang Central Hospital from 2018 to 2023 and who had subsequent HPV-DNA testing as part of their post-visit monitoring. The monitoring intervals were every 6 months.

Background: Cervical cancer is the most common gynaecological cancer worldwide, causing morbidity and mortality, especially in developing countries like Nigeria. It develops from premalignant lesions of the cervix. Human immune deficiency virus (HIV) increases the risk of dysplastic changes in the cervix.

Introduction: To report a series of patients who developed ocular surface disease related to tisotumab vedotin-tftv (TV), an antibody-drug conjugate (ADC) approved for the treatment of recurrent or metastatic cervical cancer.
Methods: This was a multicenter retrospective chart review study of patients who developed ocular surface disease related to TV between April 1st, 2022 to August 31st, 2023.
Results: Five patients were identified who developed ocular surface disease while on TV.

Introduction: High-grade cervical intraepithelial neoplasia (CIN) is a premalignant lesion of the cervix caused by persistent human papillomavirus (HPV) infection, which can lead to cervical cancer. Despite ongoing primary prevention efforts, considerable burden of illness remains. This study assessed the epidemiological, economic, and humanistic burden associated with high-grade CIN among adult women in Europe.

Both women and men are now confronted with the grave threat of cancers caused by the human papillomavirus (HPV). It is estimated that 80% of women may encounter HPV over their lives. In the preponderance of cases involving anal, head and neck, oral, oropharyngeal, penile, vaginal, vulvar, and cervical malignancies, high-risk HPV (HR-HPV) is the causative agent.
