Filter by:Cervical cancer is one of the most common cancers in women and one of the leading causes of death in women worldwide. Pre-cancerous lesions (dysplasias) are detected by the preventive smear test at the gynecologist and can thus contribute to a 100% chance of cure if they are clarified by a colposcopic examination as part of the dysplasia consultation and dysplastic lesions are then surgically removed if necessary (conization). There are few data in the literature on the influence of the menstrual cycle on the bleeding pattern during and after conization. Hormonal variations during the menstrual cycle affect both the extent of blood flow to reproductive organs and hemostasis. In the follicular phase, there is a decrease in local blood flow in the uterus and pelvic organs and an increase in coagulability. Conversely, in the luteal phase there is an increase in local blood supply and a decrease in coagulability. Therefore, it seems reasonable to perform conization in the follicular phase to possibly reduce the extent and incidence of bleeding and bleeding complications. This assumption is supported by clinical observations. For example, there is evidence from other specialties that selection of the timing of surgery, taking into account the menstrual phase, may influence the risk of bleeding. Another factor of interest in menstruation-based surgical planning is psychological vulnerability, which may also vary with the menstrual cycle. Until now, consideration of the menstrual cycle in surgical planning for conization has not been standard practice and there is no recommendation in this regard in the current S3 guideline of the German Society of Gynecology and Obstetrics. Therefore, this study now aims to answer the question under prospective randomized conditions whether LLETZ conization performed during the follicular phase results in lower blood loss and higher patient satisfaction and lower anxiety scores compared to LLETZ conization performed during the luteal phase.
The research project applies the protocol of the World Health Organisation for screening of cervical cancer, with testing of hrHPV as first screening, followed by Visual Inspection of the cervix with Acetic Acid for hrHPV-positive women and for women with minor lesions thermo-ablation of affected areas. This procedure is applied in Uganda, India and Bangladesh. In Slovakia hrHPV-positive women are offered Pap-smear and for women with Pap IV lis excision.
Cervical cancer is one of the most common cancers in women and one of the leading causes of death in women worldwide. Pre-cancerous lesions (dysplasias) are detected by the gynecologist's preventive smear test and can thus contribute to a 100% chance of cure if they are clarified by a colposcopic examination as part of the dysplasia consultation and, if necessary, surgically removed. Conization (= surgical removal of a cone of tissue from the cervix) is the method of choice for removing the diseased tissue. LLETZ conization (Large Loop Excision of the Transformation Zone) is the worldwide standard surgical procedure for conization. There is risk of local persistence of the precancerous lesion if the cervical dysplasia is not completely removed. To minimize this, the iodine test can be used. Here, a 5% iodine solution (so-called Lugol's solution) is dabbed onto the cervix uteri, resulting in an intense and characteristic brown staining of the healthy cervical epithelium. Sites without staining are termed iodine negative and may contain dysplastic cells. The strength of iodine testing lies in its high specificity, i.e., the reliable ability to exclude false-positive results. The purpose of intraoperative iodine staining is to select the resection line with a high degree of certainty in healthy (i.e., iodine-positive) tissue in order to reduce the rate of cervical dysplasia that is not completely removed (so-called non-in-sano resection, or R1 resection). Systematic survey data from the dysplasia units certified in Germany on the question of the use of intraoperative iodine testing in Germany are lacking, as is the literature as a whole. For example, the current S3 guideline of the German Society of Gynecology and Obstetrics on the diagnosis and treatment of cervical dysplasia (as of March 2020) names intraoperative iodine testing only as a possible option for performing LLETZ. In this prospective, randomized study, the investigators aim to answer the question whether LLETZ performed with the help of an iodine test with selection of the resection line in the iodine-positive area leads to a lower rate of R1 resections compared to the standard LLETZ without iodine test.
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 tampon-collected vaginal fluid and 2) ovarian cancer (OC) in plasma and tampon-collected 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.
This study is designed to demonstrate that a multimodal hyperspectral device (LuViva) is able to segregate women with abnormal screening tests into Low and High risk groups for the purpose of determining whether they require enhanced colposcopy and additional biopsies in order to increase detection of CIN2+ cervical disease.
This single-institution cross-sectional non-inferiority validation study evaluates alternative techniques and tests for primary cervical cancer screening programs in Russia, particularly: local cytology staining techniques, local HPV tests.
Cervical dysplasia is the precursor of cervical cancer. LEEP and LLETZ are standard surgical procedures to treat cervical dysplasia. There is no direct head-to-head comparison between LEEP and LLETZ in the literature regarding oncologic safety, for which complete resection of the dysplastic lesion (so-called 'in-sano resection') is the most appropriate postoperative surrogate parameter. Further clinical studies are therefore useful to optimize surgical therapy for cervical dysplasia. The primary objective of the present study is to compare LLETZ (resection of the dysplastic lesion including the transformation zone) with targeted resection of the colposcopically conspicuous lesion only (LEEP) and to compare it with regard to oncological safety (defined as non-in-sano rate).
Cervical cancer is one of the most common cancers in women and one of the leading causes of death in women worldwide. Pre-cancerous lesions (dysplasias) are detected by the screening smear test at the gynecologist's office and can thus contribute to a 100% chance of cure if they are clarified by a colposcopic examination as part of the dysplasia consultation. To detect cervical dysplasia during colposcopic examination, the effect of diluted acetic acid on the epithelium of the cervix uteri is utilized. Metaplastic epithelium and low-grade dysplasia are visually noticeable by a slight white staining. Biopsies are then taken from these areas for further diagnosis. The colposcopy itself and especially the colposcopic targeted biopsy of the cervix are painful. Virtual reality (VR) is a new method for 360° three-dimensional viewing of image content. A number of studies have shown that the use of VR can have a positive impact on the course of medical interventions. Randomized studies on the effectiveness of VR in a collective of women with colposcopically targeted biopsy of the cervix are not available according to a recent literature search (PubMed search of 12/30/2020; search terms: cervical biopsy, colposcopy, pain relief, pain control, virtual reality). In studies of our research group on colposcopy, we found increased pain scores especially in younger patients, but also in obese patients and smokers. A controlled study on the effectiveness of VR in colposcopically targeted biopsy is therefore useful. In our study, we now want to answer the question under prospective conditions whether the use of VR before the start or before the start and during colposcopy compared to no intervention leads to a significant increase in patient satisfaction and/or a reduction in pain in the context of clarification colposcopy and colposcopically targeted biopsy.
The Self-Testing options in the Era of Primary HPV screening for cervical cancer (STEP) trial will evaluate effectiveness of home-based HPV kits for improving cervical cancer screening uptake and its cost-effectiveness. The investigators will compare cervical cancer screening uptake within six months among women randomized to different outreach approaches based on prior screening behavior: A) Adherent and coming due: direct mail HPV kit vs. opt-in HPV kit vs. education; B) Overdue: direct mail HPV kit vs. education; C) Unknown: opt-in HPV kit vs. education.
The study will investigate if implementation of "see and treat" in the outpatient clinic can optimize the diagnosis, clinical follow-up and treatment of older women with positive cervical screening test.
