Adnexal Mass

The overarching objective of this project is to develop a pan-gynecologic cancer detection test using gynecologic (unique endometrial, cervical, and ovarian cancer) cancer-specific methylated DNA markers and high-risk human papilloma virus (HR-HPV) detected in vaginal fluid and/or plasma. This proposal defines Phase II MDM-based cancer detection studies in endometrial cancer (EC) and endometrial hyperplasia with atypia (AEH) in vaginal fluid and 2) ovarian cancer (OC) in plasma and vaginal fluid. Additionally, it defines necessary Phase I MDM-based cancer detection and exploratory aims to test novel cervical cancer (CC) MDMs and test the specificity of cancer-specific MDMs among various common benign gynecologic pathologies.er detection and exploratory aims to test novel cervical cancer MDMs and test the specificity of cancer-specific MDMs among various common benign gynecologic pathologies.

In this study, a prospective study is used to select patients who will undergo intra-abdominal endoscopic single-port surgery system for benign gynecological diseases from February 2025 to December 2026 in the Second Affiliated Hospital of Wenzhou Medical University, including hysterectomy, myomectomy, ovarian cyst removal and adnexectomy. The study will perform statistical analysis to evaluate the feasibility and the main factors affecting the safety of intra-abdominal endoscopic single-port surgery system(SR-ENS-600) used in gynecological day surgery.

Transvaginal Natural Orifice Transluminal Endoscopic Surgery (vNOTES) is a recent innovation in minimally invasive surgery which has already proven its non-inferiority to conventional abdominal laparoscopy (CAL) for hysterectomy in terms of efficiency and safety. However, the investigators note a lack of medical literature and no specific randomized controlled trial (RCT) assessing women's sexual function after vNOTES for benign adnexal surgery. The aim of this RCT is to confirm the non-inferiority of the vNOTES approach for benign adnexal pathology compared to CAL on women's sexual function. Secondary outcomes will evaluate vNOTES's efficiency, morbidity and postoperative complications compared to CAL for benign adnexal surgery. The relationship between adnexal mass morcellation/aspiration and the quality of the histological analysis on surgical specimens will also be evaluated as secondary outcome.

This multicenter observational study aims to validate the IOTA Simple Rules, Benign Descriptors, and ADNEX model in a cohort of patients equal or under the age of 20. Moreover, the study aims to evaluate the diagnostic accuracy of subjective assessment by ultrasound and to analyze the rate of complications in patients treated conservatively.

Research on automatic detection of ovarian mass and intelligent auxiliary diagnosis system based on multimodal ultrasound images.

After implementation of systematic image description of adnexal masses, we aim to improve and evaluate our use of available imaging methods and biomarkers for classifying adnexal masses and distinguishing between benign and malignant adnexal masses in the hands of clinicians in Central Denmark Region. Secondarily, we want to improve our management of adnexal masses by evaluating the complications and longitudinal changes in conservatively managed adnexal masses. Data is registered prospectively but analyzed retrospectively.
