Cell-free DNA in the management of prostate cancer:Current status and future prospective

摘要

Objective:With the escalating prevalence of prostate cancer(PCa)in China,there is an urgent demand for novel diagnostic and therapeutic approaches.Extensive investigations have been conducted on the clinical implementation of circulating free DNA(cfDNA)in PCa.This review aims to provide a comprehensive overview of the present state of cfDNA as a biomarker for PCa and to examine its merits and obstacles for future clinical utilization.Methods:Relevant peer-reviewed manuscripts on cfDNA as a PCa marker were evaluated by PubMed search(2010e2022)to evaluate the roles of cfDNA in PCa diagnosis,prognosis,and prediction,respectively.Results:cfDNA is primarily released from cells undergoing necrosis and apoptosis,allowing for non-invasive insight into the genomic,transcriptomic,and epigenomic alterations within various PCa disease states.Next-generation sequencing,among other detection methods,enables the assessment of cfDNA abundance,mutation status,fragment characteristics,and epigenetic modifications.Multidimensional analysis based on cfDNA can facilitate early detection of PCa,risk stratification,and treatment monitoring.However,standardization of cfDNA detection methods is still required to expedite its clinical application.Conclusion:cfDNA provides a non-invasive,rapid,and repeatable means of acquiring multidimensional information from PCa patients,which can aid in guiding clinical decisions and enhancing patient management.Overcoming the application barriers of cfDNA necessitates increased data sharing and international collaboration.
