The purpose of this study is to see if giving chemo-therapy for colon cancer before surgery can shrink the cancer and lead to a higher rate of cure than operating first and then giving chemotherapy. Standard treatment for colon cancer is to first operate, and then, if the tumor is advanced, give chemotherapy for about 6 months. However, surgery delays the time until chemotherapy can start, since the body needs time to heal from the operation. During this time any cancer cells that remain in the body that were not removed by the operation may be allowed to grow. Giving chemotherapy first could attack the cancer cells right from the start, not only at the tumor site that we know of, but also at the site of any cancer cells that may have spread to other parts of the body. Another possible reason why giving chemo therapy first might work better is that the blood vessels that feed the cancer cells are intact before surgery and thus chemotherapy can travel directly to the cancer.
This study will also use the drug bevacizumab, in addition to the standard chemotherapy. Bevacizumab has been on the market since 2004 for colon cancer that has spread to other organs, but its use in earlier stage colon cancer, as planned in this trial, is still under study.

RATIONALE: Recently, the importance of prognosis according to the location of the primary tumor in colorectal cancer has been raised. In the CALGB / SWOG 80405 study published in 2016, the...
The main cause of recurrence after surgical treatment of colon cancer is distant metastasis. Neoadjuvant chemotherapy has potential benefits of improving the effectiveness of chemotherapy....
The primary working hypothesis is that preoperative chemo-sensitivity testing using fluorodeoxyglucose positron emission tomography (FDG-PET) performed before and after one course of FOLFO...
This 2-arm study will compare the pharmacokinetics and safety of Avastin (bevacizumab) at steady state under two different dosing regimens, in combination with XELOX (oxaliplatin+capecitab...
The combination of oxaliplatin, leucovorin and fluorouracil (FOLFOX) has been established as postoperative adjuvant chemotherapy for stage III colon cancer. However, the safety and efficacy of neoadju...
Conversion therapy can convert unresectable metastatic colorectal cancer (mCRC) into resectable. However, the optimal conversion regimen was not yet defined. This meta-analysis aimed to compare the ef...
Purpose Given the cumulative neurotoxicity associated with oxaliplatin, a shorter duration of adjuvant therapy, if equally efficacious, would be advantageous for patients and health-care systems. Meth...
The recommended standard of care for patients after resection of stage III colon cancer is adjuvant 5FU-based chemotherapy - FOLFOX (fluorouracil, leucovorin with oxaliplatin) - or CAPOX (capecitabine...
Background Since 2004, a regimen of 6 months of treatment with oxaliplatin plus a fluoropyrimidine has been standard adjuvant therapy in patients with stage III colon cancer. However, since oxaliplati...

The segment of LARGE INTESTINE between the CECUM and the RECTUM. It includes the ASCENDING COLON; the TRANSVERSE COLON; the DESCENDING COLON; and the SIGMOID COLON.
The segment of LARGE INTESTINE between ASCENDING COLON and DESCENDING COLON. It passes from the RIGHT COLIC FLEXURE across the ABDOMEN, then turns sharply at the left colonic flexure into the descending colon.
Tumors or cancer of the COLON or the RECTUM or both. Risk factors for colorectal cancer include chronic ULCERATIVE COLITIS; FAMILIAL POLYPOSIS COLI; exposure to ASBESTOS; and irradiation of the CERVIX UTERI.
The segment of LARGE INTESTINE between TRANSVERSE COLON and the SIGMOID COLON.
Colon or Colorectal cancer is the growth of malignant polyps on the colon, bowel, anus and rectum. Growths in these locations can be benign, and removed by colonoscopy, but they have a risk of becoming malignant. About 10 per cent of bowel cancer...
