Abstract:

Ovarian cancer has the highest mortality rate and poorest prognosis in gynecologic cancers. Presently, there is a lack of effective tools for early diagnosis and early screening for ovarian cancer. Methylation plays a key role in the origin and progression of ovarian cancer. Based on liquid biopsy technique, several studies had been conducted to analyze the efficacy of cell-free DNA methylation detection in diagnosing ovarian cancer. The overall median accuracy of cell-free DNA methylation reached 85%, which is superior to traditional protein molecular markers such as CA125. The findings from methylation detection in ovarian cancer tissue were also closely related to patients' survival outcomes and drug sensitivity. The advances and improvement of methylation assays for ovarian cancer hold promise for providing novel direction and opportunities in exploring molecular strategies for diagnosing and treating.
