Early screening technology can improve the survival rate of breast cancer patients. Traditional mammography and ultrasonography have limitations on performance in clinical practice. Extracellular vesicles, one of the three major resources of liquid biopsy, contain multi-omics information that can be used to discover effective biomarkers for early diagnosis and screening of cancers.~In this study, we are going to isolate glycosylated extracellular vesicles from serum of cancer patients and non-cancer people with the novel GlyExo-Capture technology, and perform miRNA sequencing to selected out breast cancer-related markers. Then an early diagnosis model of breast cancer based on the GlyExo-Capture platform is able to be established using machine learning techniques and validated by qPCR experiments.
This is a prospective, single-center, non-randomized, cohort study designed to evaluate the clinical diagnostic performance of glycosylated extracellular vesicles and their contents for early detection of breast cancer.
