Comparative Study of Cetuximab and Radiation Vs Surgery Before or After Radiation in Patients With Colorectal Carcinoma

Patients will receive Cetuximab and Radiation Therapy. Patients will receive a dose of Cetuximab through Intravenous (IV). The initial dose is 400 mg/m2 administered as a 120-minute intravenous infusion (maximum infusion rate 10 mg/min) and weekly dose is 250 mg/m2 infused over 60 minutes (maximum infusion rate 10 mg/min) until disease progression or unacceptable toxicity. Radiation treatment for Colorectal Cancer are Intensity Modulated Radiation Therapy (IMRT). IMRT delivers radiation directly to the tumor and modulates the intensity of the radiation with laser accuracy.

Patients will undergo Surgery before or after Radiation Therapy. Colorectal Cancer Surgery are Colon resection (Colectomy), Rectum resection (Proctectomy), Colostomy, and Radiofrequency ablation. Radiation treatment for Colorectal Cancer are Intensity Modulated Radiation Therapy (IMRT). IMRT delivers radiation directly to the tumor and modulates the intensity of the radiation with laser accuracy.
