Summary

Epithelial ovarian cancer constitutes one of the most common gynecological malignancies.Because the ovaries lie in the deep pelvic cavity,most ovarian cancer patients are asymptomatic, rendering the majority often diagnosed at an advanced stage.ctDNA in cancer patients often bears similar genetic and epigenetic features to the related tumor DNA.This study aims to detect plasma ctDNA in Diagnosis of Epithelial Ovarian Cancer.

Detailed description

Epithelial ovarian cancer constitutes one of the most common gynecological malignancies, with an incidence rate of 3-12/100 000 woman per year. Because the ovaries lie in the deep pelvic cavity,most ovarian cancer patients are asymptomatic, rendering the majority often diagnosed at an advanced stage. Liquid biopsy, which is meant to detect cancers by sequencing the DNA in a few drops of a person's blood. It may detect cancers early, even before symptoms arise, when there is just a few cells in the blood circulation. ctDNA in cancer patients often bears similar genetic and epigenetic features to the related tumor DNA. There is evidence that some of the ctDNA originates from tumor tissue. This, and the fact that ctDNA can easily be isolated from the circulation and other body fluids of patients, makes it a promising candidate as a non-invasive biomarker of cancer. This study aims to detect plasma ctDNA in Diagnosis of Epithelial Ovarian Cancer.
