This study is looking to develop diagnostic tests for colon cancer through developing a highly sensitive real-time marker assay that is able to detect colon cancer DNA in blood plasma.

This trial is comparing three different combination chemotherapy regimens [oxaliplatin with fluorouracil and leucovorin calcium] to see how well they work when given with or without cetuximab in treating patients who have undergone surgery for stage III colon cancer.

The main objective of the study is evaluate the effectiveness of aflibercept in increasing the overall survival in patients with metastatic colorectal cancer treated with irinotecan and 5-FU and that have previously failed an oxaliplatin based treatment for metastastic disease.

This trial is comparing the 3-year disease-free survival of patients at high risk for recurrence treated with oxaliplatin, leucovorin, fluorouracil, and bevacizumab to see how well they work compared to oxaliplatin, leucovorin, and fluorouracil.

This trial is studying cetuximab and/or bevacizumab when given together with combination chemotherapy [with either oxaliplatin, fluorouracil, and leucovorin calcium (FOLFOX) OR irinotecan hydrochloride, fluorouracil, and leucovorin calcium (FOLFIRI)] to compare how well they work in treating patients with metastatic colorectal cancer.

This trial is studying radiation therapy and either capecitabine or fluorouracil with or without oxaliplatin and comparing them to see how well they work when given before surgery in treating patients with resectable rectal cancer.
