title: Cancer mucosa antigens as a novel immunotherapeutic class of tumor-associated antigen.
abstract: Colorectal cancer is a leading cause of cancer-related mortality worldwide. Surgery and chemoradiation exhibit incomplete efficacy and, ultimately, 50% of patients die of metastatic disease. In the context of that unmet clinical need, immunotherapeutic approaches have enjoyed limited success, partly because of a paucity of suitable antigen targets. However, exploitation of immune compartmentalization, employing antigens with expression restricted to normal intestinal mucosa and derivative colorectal tumors--cancer mucosa antigens (CMAs)--may represent a previously unrecognized class of immune targets supporting efficacious antitumor immunotherapy. Guanylyl cyclase C (GCC) is an intestine/colorectal cancer-restricted protein ideally suited as the first CMA for clinical evaluation.
