Superficial endometriosis (SE) is the most prevalent form, yet it remains underdiagnosed due to subtle clinical and imaging presentations. Traditionally, diagnosis relies on laparoscopy, which is relatively invasive and often contributes to diagnostic delay. With advancements in imaging techniques, especially transvaginal ultrasound (TVS), a reassessment of the diagnostic approach for SE is needed. This review updates the understanding of SE diagnostics and integrates both historical perspectives and contemporary clinical insights.</p><p><strong>Objectives: </strong>The review aimed to explore advancements in the diagnosis of SE, focusing on the growing role of TVS as a non-invasive diagnostic tool. Additionally, it seeks to highlight emerging diagnostic challenges and present new approaches to managing SE to offer updated recommendations for clinicians.</p><p><strong>Methods: </strong>A comprehensive literature search was conducted using PubMed, MEDLINE, and Google Scholar. The following keywords were used: \"superficial endometriosis,\" \"diagnostic pathways,\" \"endometriosis diagnosis,\" \"superficial lesions,\" \"transvaginal ultrasound,\" \"laparoscopy,\" \"non-invasive imaging,\" and \"diagnostic accuracy.\" Only English-language articles were included, focusing on original research, metanalyses, and clinical guidelines, offering historical and current perspectives. In addition to the literature review, contemporary insights were gathered from our clinical practice at a tertiary endometriosis clinic to offer real-world context to the literature findings.</p><p><strong>Outcome: </strong>The review highlights TVS as a promising non-invasive method for diagnosing SE. While SE has historically been diagnosed through laparoscopy, TVS is gaining recognition as a valuable tool for detecting SE lesions, particularly through the identification of key sonographic features such as hyperechoic foci and cystic spaces. These advancements help overcome the challenges posed by the variability of SE presentation on imaging. Emerging techniques, such as sonoPODography, further enhance SE diagnosis and offer the potential for broader clinical application. Despite challenges such as the need for operator expertise and variability in lesion presentation, the literature and clinical insights support the growing utility of TVS in diagnosing SE.</p><p><strong>Conclusions and outlook: </strong>TVS has significant potential as a non-invasive diagnostic tool for SE. While limitations such as variability in sensitivity and the need for operator expertise remain, TVS can significantly reduce reliance on invasive methods like laparoscopy. Additionally, the review provides insights into managing cases, where TVS results are negative for SE.

The optimal conditions for urine sample storage were identified by comparing the HPV detection rates under various conditions.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;Urine stored in a BD Probe Tec™ (QxUPT) for less than 72 h at room temperature was found to have the highest HPV positivity rate. Under these conditions, the detection rates of HPV in urine, cervical, and vaginal samples were examined. HPV type 16 was detected in 41.7% of the cervical samples, type 18 in 10%, and types 31 and 52 in 12.6% each. The concordance rate for HPV testing between clinician-collected cervical and urine samples was 63.9% (kappa: 0.34; 95% CI: 0.21-0.47), and that between clinician-collected cervical and self-collected vaginal samples was 77.8% (kappa: 0.68; 95% CI: 0.53-0.83), indicating good concordance. In a population with an HPV-related lesion/tumor prevalence of approximately 70%, the sensitivity of HPV testing was 82.7% for the cervix, 46.4% for urine, and 75.7% for vaginal samples.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Limitations: &lt;/strong&gt;The primary limitation is the lower detection rate of HPV in spot urine samples than in other sample types, indicating room for methodological improvement. The study's findings are based on a specific population, which may limit generalizability.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusions: &lt;/strong&gt;We investigated the optimal self-collected urine-to-testing time and temperature. Self-collected vaginal and urine HPV tests show moderate-high concordance with clinician-collected cervical HPV tests, suggesting their potential utility for women who do not undergo regular cancer screening. However, the sensitivity was not high in spot urine. Therefore, further large-scale studies are needed to verify these findings and optimize testing methods to encourage broader participation in cancer screening programs.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Objectives: &lt;/strong&gt;The high incidence of invasive cervical cancer among those who have not undergone cancer screening is a serious problem","PeriodicalId":12952,"journal":{"name":"Gynecologic and Obstetric Investigation","volume":" ","pages":"143-152"},"PeriodicalIF":2.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142390065","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Corresponding controlled experiments were performed to analyze whether overexpression of METTL14, N6-methyladenosine (m6A) methylated ZEB1 mRNA, upregulation of ZEB1, and activating the mitogen-activated protein kinase kinase (MEK)/extracellular signal-regulated kinase (ERK) can affect the proliferation, migration, and invasion of HEM15A cells. Materials, Setting, and Methods: HEM15A and HESCs were cultured in vitro. HEM15A cells were treated with oe-METTL14 and oe-zinc finger E-box-binding protein 1 (ZEB1) plasmids, 3-deazaadenosine (3-DAA) and the MEK/ERK pathway inhibitor isoprenaline (ISO). After identifying HEM15A and HESCs, METTL14, ZEB1, p-ERK1/2/ERK1/2, and p-MEK/MEK levels, and cell proliferation, migration, and invasion were assessed. The modification sites of ZEB1 and m6A were predicted using SRAMP database, with an m6A modification level assessed by MeRIP. The binding of YT521-B homology domain 2 (YTHDF2) to ZEB1 messenger RNA (mRNA), and ZEB1 stability and mRNA level were tested.</p><p><strong>Results: </strong>Compared with HESCs, METTL14 level in HEM15A was significantly reduced. METTL14 overexpression in HEM15A prominently increased its proliferation, migration, and invasion. METTL14 overexpression notably elevated m6A-methylated ZEB1 mRNA level and reduced the stability and expression of ZEB1 mRNA. Further m6A modification inhibition increased ZEB1 mRNA stability and mRNA and protein levels and decreased ZEB1 m6A modification level. ZEB1 upregulation partially reversed METTL14 overexpression-inhibited HEM15A proliferation, migration, and invasion. METTL14 inhibited the MEK/ERK signaling activation by regulating ZEB1, and the MEK/ERK signaling activation partly averted METTL14-suppressed proliferation, migration, and invasion.</p><p><strong>Limitations: </strong>The effects of METTL14 on other growth aspects of HEM15A cells and the relation between ZEB1 and m6A require further investigation.</p><p><strong>Conclusions: </strong>METTL14 lowered ZEB1 expression by regulating ZEB1 m6A modification levels, thereby inhibiting the activation of the MEK/ERK pathway and ESC proliferation, migration, and invasion.</p>","PeriodicalId":12952,"journal":{"name":"Gynecologic and Obstetric Investigation","volume":" ","pages":"42-54"},"PeriodicalIF":2.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141456336","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
