What is Chemotherapy for Colorectal Cancer?
Chemotherapy for colorectal cancer involves anti-cancer drugs that destroy or slow the growth of cancer cells. It can be administered intravenously or orally and is integral to treating both localized, advanced, and metastatic disease of colorectal cancer.
Types of Chemotherapy for Colorectal Cancer
Common chemotherapy regimens include:
- FOLFOXCombination of folinic acid (leucovorin), fluorouracil (5-FU), and oxaliplatin
- FOLFIRICombination of folinic acid, fluorouracil, and irinotecan
- FOLFOXIRICombination of folinic acid, fluorouracil, oxaliplatin, and irinotecan
- CAPOX (or CAPEOX)Combination of capecitabine and oxaliplatin
Chemotherapy can also be given along with radiation (chemoradiation) or targeted therapies, depending on individual patient factors.
When Chemotherapy Is Needed
Adjuvant Chemotherapy in Colorectal Cancer
Adjuvant chemotherapy is administered after surgical resection to destroy remaining microscopic cancer cells and prevent recurrence. It is usually indicated in colorectal cancer at high-risk stage II and in stage III disease.
Chemotherapy for Advanced or Metastatic Disease
Chemotherapy remains one of the main treatments for colorectal cancer in the stage of metastasis; targeted therapy or immunotherapy is combined to enhance survival.
Treatment Process for Chemotherapy
Chemotherapy for colorectal cancer is given in cycles, with 2 to 3-week intervals that allow the body to recover. The treatment usually lasts from 3 to 6 months, depending on the regimen and the stage of cancer. Sessions are mostly outpatient and can include intravenous infusions or oral medications.
