There is an unmet need for improved therapeutic paradigms in colorectal cancer, the 3rd leading cause of cancer and 2nd leading cause of cancer mortality worldwide. This need is underscored by the populations in jeopardy, including the ~100 million people in the US over 50 y that have a 1:8 risk associated with a disease-specific mortality of 50%. Mortality reflects metastatic disease: ~50% of patients initially present with regional or distant metastases, while ~20% present with occult metastases. Beyond the general population risk, there is an established stage-specific difference in outcomes in pN0 (node negative) African Americans with colorectal cancer, who exhibit ~40% excess mortality attributable to race. Reductions in mortality have been hampered by the absence of effective chemo-, radio-, and immuno- therapeutic approaches to metastatic disease. In that context, immunotherapy has been disappointing, in part, reflecting the absence of antigens that are tumor-specific, immunogenic, and universally associated with neoplasia. Moreover, the gap in survival between African Americans and Caucasians specifically reflects the inability to identify those with occult metastases who are at increased risk for developing recurrent disease.
