Yes, there are several alternative chemotherapy regimens for the treatment of colorectal cancer. One common alternative is FOLFIRI, which includes folinic acid, fluorouracil, and irinotecan. Another option is CAPOX (or XELOX), which combines capecitabine (an oral prodrug of 5-FU) with oxaliplatin. The choice of regimen often depends on various factors, including the patient's overall health, the stage of the cancer, and how well the patient tolerates the drugs.
