Colorectal cancer treatments include chemotherapy drugs, e.g., 5-fluorouracil, capecitabine, irinotecan, and oxaliplatin together with bevacizumab, an anti-angiogenic agent targeting the vascular endothelial growth factor (VEGF), and cetuximab which targets the endothelial growth factor (EGF). Here, VEGFA is linked to colorectal cancer.
