Colorectal Cancer Treatment
Colorectal Cancer Treatment is a common treatment option for patients with stage III or stage IV colorectal cancer. Chemotherapy drugs work to either destroy cancer cells outright, or impede their ability to grow and reproduce. This type of Colorectal Cancer Treatment is usually administered through a vein or the hepatic artery.When given as an adjuvant therapy (i.e., additional treatment following colorectal cancer surgery), chemotherapy can:
- Help destroy colorectal cancer cells that remain after surgery
- Prevent colorectal cancer from spreading to other parts of the body (e.g., liver)
- Help lower the risk of cancer recurrence
Chemotherapy given prior to colorectal cancer surgery (neoadjuvant therapy) can help reduce the size of tumors. If you have rectal cancer, this type of treatment may be particularly helpful. Our oncologists may recommend a combination of chemotherapy and radiation therapy, followed by rectal cancer surgery.
What is chemotherapy?
Chemotherapy is the use of anticancer drugs designed to slow or stop the growth of rapidly dividing cancer cells in the body. It may be used:
- As a primary treatment to destroy cancer cells
- Before another treatment to shrink a tumor
- After another treatment to destroy any remaining cancer cells
- To relieve symptoms of advanced cancer
At Cancer Treatment Centers of America® (CTCA), our medical oncologists are experienced in delivering targeted, individualized chemotherapy options while also proactively managing side effects..
Chemotherapy delivery methods
Some chemotherapy delivery methods include:
- Orally (by mouth as a pill or liquid)
- Intravenously (by infusion into a vein)
- Topically (as a cream on the skin)
- Direct placement (via a lumbar puncture or device placed under the scalp)
When chemotherapy drugs travel through the bloodstream to reach cells throughout the body, it is called systemic chemotherapy. When chemotherapy drugs are directed to a specific area of the body, it is called regional chemotherapy.
