Serum tumor markers for the diagnosis of cholangiocarcinoma in primary sclerosing cholangitis.

abstract：:A variety of noninvasive molecular approaches to colorectal cancer screening are emerging with potential to improve screening effectiveness and user-friendliness. These approaches are based on the sensitive assay of molecular markers in stool, blood, and urine samples. New methods, especially next generation stool-bas...
