This study investigates if circulating tumor DNA (ctDNA) and other tumor-related molecules/chemicals released in the blood can help doctors predict if colorectal cancer may come back or spread. Tumors shed DNA and other cancer related chemicals into the blood that can be identified and studied further to provide information about the cancer. Information gathered from this study may help researchers better understand if ctDNA found in the blood can predict whether colorectal cancer may come back or spread.
PRIMARY OBJECTIVES: I. Demonstrate ability to monitor cancer-specific deoxyribonucleic acid (DNA), ribonucleic acid (RNA), and proteomic alterations from plasma. II. Improve detection of recurrences post completion of curative therapies through monitoring of plasma cancer-specific DNA, RNA and proteomic alterations. SECONDARY OBJECTIVES: I. Qualitative and quantitative changes in cancer-specific plasma alterations during neoadjuvant, adjuvant therapies and surveillance. II. Disease free survival (DFS) of patients with detectable cancer-specific plasma alterations. III. Overall survival (…
