About

The main cause of recurrence after surgical treatment of colorectal cancer is distant metastasis. Neoadjuvant chemotherapy has potential benefits of improving the effectiveness of chemotherapy. Preoperative chemotherapy may eradicate microscopic metastatic cancer cells earlier than adjuvant chemotherapy, reduce cancer cell spillage during surgery, and lessen the invasiveness of surgical resection. The FOLFOXIRI regimen has been shown to have a high objective efficiency in advanced colorectal cancer. This phase II trial is to explore the pathological remission rate and safety of stage II/III locally advanced colon cancer with high risk of recurrence to FOLFOXIRI regimen of neoadjuvant chemotherapy alone.
