摘要: Colorectal cancer is one of the major causes cancer-related death in Western world. Patient survival highly dependent on tumor stage at time diagnosis. Reduced sensitivity to chemotherapy still a obstacle effective treatment advanced disease. Due fact that colorectal mostly asymptomatic until it progresses stages, implementation screening programs aimed early detection essential reduce incidence and mortality rates. Current diagnostic methods range from semi-invasive procedures such as colonoscopy noninvasive stool-based tests. The combination absence symptoms, nature currently used methods, suboptimal accuracy fecal blood tests results diagnosis stages significant number individuals. Alterations gene expression leading carcinogenesis are reflected dysregulated levels nucleic acids proteins, which can be for development novel, minimally invasive molecular biomarkers. purpose this review discuss commercially available well highlight some new candidate predictive prognostic markers tumor, stool, samples.
