Abstract Background Currently, due to the invasive nature of colonoscopy and the associated pain, people avoid undergoing the procedure, making it difficult to detect the majority of potential early stage colorectal carcinoma/precancerous lesions or advanced adenoma.Advanced colorectal adenoma is the main precursor to the development of colorectal carcinoma.Therefore, improving advanced colorectal adenoma detection rate can significantly decrease the development and morbidity of click here colorectal carcinoma.

Accordingly, a non-invasive method to screen high-risk people for colonoscopy in clinical practice is urgently needed.Main text With the development of medical technology, screening methods for colorectal carcinoma are emerging rapidly, and diverse non-invasive methods are being developed.Cell-free DNA (cfDNA), commonly referred to as liquid biopsy, has promising application prospects as a minimally invasive strategy for early screening of colorectal cancer.

CfDNA has already been applied in the field of prenatal diagnosis, advanced carcinoma, and organ transplantation, and the application cfDNA in advanced colorectal adenoma is at the cutting-edge of current research.Thus, this review summarizes the dorisvale station for sale progress in research on different biological characteristics of cfDNA and its utility in the screening of advanced colorectal adenoma, including sizes of cfDNA molecules, end signature of cfDNA (preferred ends, end motifs, jagged ends), nucleosomal footprints, cfDNA topology, cfDNA methylation, and cfDNA integrity.Conclusions We hope that this review will advance this promising research field.
