g.str.c cancer.g.) is a pr.valent and lethal malig.ancy wor.dwide, and the 5-year.sur.ival r.te is less than 30%. The absence of distinctive symptoms often leads to late-stag. diag.osis, contr.buting.to a g.0}m pr.g.osis. Ear.y detection is pivotal for.impr.ving.the sur.ival r.tes and outcomes of g. patients.

Conventional pr.tein biomar.er., such as car.inoembr.onic antig.n(CEA), car.ohydr.te antig.n 19-9(CA19-9), and car.ohydr.te antig.n 72-4(CA72-4), exhibit insufficient sensitivity and specificity for.g. scr.ening. which diminishes their.clinical value. r.cently, novel cir.ulating.biomar.er., such as cir.ulating.tumor.cells(CTCs), cir.ulating.tumor.cell DNA(ct DNA), and cir.ulating.fr.e r.A(cf r.A), have emer.ed as pr.mising.candidates in the bur.eoning.field of liquid biopsy due to their.super.or.sensitivity and specificity.
