Background: Cervical carcinoma and endometrial carcinoma are the most common gynecologic cancers worldwide. Forkhead-box R2 (FOXR2) plays an important role in the progression of various malignant tumors. However, the effects of FOXR2 on the development of uterine lesions remain unclear.
Objectives: This prospective observational study aimed to investigate the diagnostic performance of FOXR2 and transvaginal three-dimensional power Doppler ultrasonography (3D-PDU) for malignant uterine lesions.
Material And Methods: This study included 404 uterine lesion patients and 200 healthy individuals who visited the hospital for a physical examination from April 2014 to May 2016. All patients received FOXR2 detection and 3D-PDU examination at admission. The demographic data and clinical data, including age, body mass index (BMI), and the International Federation of Gynecology and Obstetrics (FIGO) stage, were collected. All the patients were followed up for 5 years. The overall survival (OS) was analyzed using Kaplan-Meier (K-M) curve analysis. The diagnostic value of FOXR2 and 3D-PDU was evaluated using receiver operating characteristic (ROC) curves.
Results: Serum levels of FOXR2 mRNA were upregulated in patients with malignant uterine lesions. Patients with high expression of FOXR2 showed a higher expression of the cancer biomarkers CA125, CA199, CEA, and SCCA. It was also found that FOXR2 expression was associated with the clinical outcomes of patients with malignant uterine lesions. Moreover, higher expression of FOXR2 predicted a poor prognosis. The combined use of FOXR2 and 3D-PDU showed favorable potential for the diagnosis of malignant uterine lesions, especially for cervical carcinoma and endometrial carcinoma.
Conclusions: The combination of serum FOXR2 and transvaginal 3D-PDU has a potential in the diagnosis of uterine lesions.

Background: Vulvar squamous cell carcinoma incidence is increasing, especially among women under 60, largely attributed to human papillomavirus infections. Precursor pre-invasive vulvar lesions are frequently underdiagnosed. Routine vulvar inspection during cervical cancer screening could offer an opportunity for the detection of these lesions.

It is unknown whether this applies to patients with low-risk disease following simple hysterectomy.
Methods: Among patients who underwent simple hysterectomy in the Simple Hysterectomy And PElvic node assessment trial, univariate and multivariate Cox models were used to assess the association of minimally invasive versus open surgery with clinical outcomes, including pelvic and extra-pelvic recurrence-free survival, overall recurrence-free survival, and overall survival.

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.

Anti-Müllerian hormone (AMH) protects the ovarian reserve from chemotherapy, and this effect is most pronounced with Doxorubicin (DOX). However, DOX toxicity and AMH rescue mechanisms in the ovary have remained unclear. Herein, we characterize the consequences of these treatments in ovarian cell types using scRNAseq.

In cervical cancer screening, cytology is used as a triage test to refer high-risk human papillomavirus (HR-HPV)-positive women for colposcopy, but its accuracy is inadequate. The present study aimed to demonstrate that the presence of atypical cells with large vacuoles in the cytoplasm of parabasal cells, referred to as vacuolated parabasal cells (VPCs), which are observed in the Pap smears of HPV-positive women, is associated with specific HPV genotypes. Among 2175 patients, 310 with a single HR-HPV infection and cytological diagnosis of high-grade squamous intraepithelial lesions (HSIL) or atypical squamous cells not excluding HSIL (ASC-H) were included, of which 86 were infected with HPV16.
