Trop-2 is a cell surface glycoprotein1 that is highly expressed in a wide variety of epithelial cancers. There is little or no expression of Trop-2 in adult somatic tissue.2 Trop-2 is a novel calcium signal transducer3 involved in the regulation of cell- cell adhesion.4 It is an oncogene that has potential as a therapeutic target.2 It is a possible candidate gene for diagnosis and molecular target therapy of colorectal cancer.5
