This article aims to explore the molecular mechanism of DNA abnormal methylation pattern in epithelial ovarian cancer, especially its application in molecular subtyping and clinical diagnosis.Firstly, this article will review the relevant background of epithelial ovarian cancer and its molecular subtyping, and introduce the existing research progress of DNA methylation and the latest technical means. Then, this article will explain the application of DNA methylation in molecular subtyping of epithelial ovarian cancer, including P53 mutation type, BRCA1/2 mutation type, CpG island methylation type, and emphasize its superiority and application prospect in molecular subtyping.精品文档---下载后可任意编辑Finally, this article will focus on the application of DNA abnormal methylation pattern in clinical diagnosis of epithelial ovarian cancer, discussing its application prospect in early diagnosis, prognosis judgment, treatment monitoring, etc., in order to provide new directions and ideas for the diagnosis and treatment of epithelial ovarian cancer.Keywords: Epithelial ovarian cancer; DNA abnormal methylation; Molecular subtyping; Clinical diagnosis
