A key initiative involves collaborating with the Royal Thai College of Obstetricians and Gynaecologists and the National Cancer Institute, Thailand to regularly update and release clinical practice guidelines (CPGs) for gynecologic cancer. The TGCS released the first CPG for endometrial cancer (EMC) in 2011. Following significant advancements in disease understanding and the major revision of EMC staging by the International Federation of Gynecology and Obstetrics in 2023, national experts collaborated to update the guideline for EMC. The key components of the CPG for EMC covered screening, diagnostic indications and methods, primary treatment including surgical approaches and procedures, pathological processes, adjuvant therapies, and the management of recurrent and advanced diseases through medical or surgical means. The guideline was based on scientific evidence, recommendations from international organizations, and the unique healthcare context of Thailand. The final version reflects a consensus reached through extensive discussions among TGCS members. To share our work with international organizations and healthcare professionals, an English version of the CPG was developed. While it mirrors the content of the Thai version, it differs in length and level of detail. The English version additionally included the level of evidence and a recommendation summary for each section, reflecting common domestic practices, available resources, and coverage under health reimbursement systems.</p>","PeriodicalId":15868,"journal":{"name":"Journal of Gynecologic Oncology","volume":" ","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143670147","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
