Understanding Chemotherapy for Colorectal Cancer
Chemotherapy is a common treatment for colorectal cancer, often used in combination with surgery and radiation therapy. It works by targeting rapidly dividing cells, which include cancer cells. The goal of chemotherapy can vary depending on the stage of the cancer. It can be used to shrink a tumor before surgery, kill any remaining cancer cells after surgery, or control the growth of advanced cancer.
Why Chemotherapy is Used for Colorectal Cancer
Chemotherapy plays a vital role in treating colorectal cancer due to its ability to reach cancer cells throughout the body. This is particularly important if the cancer has spread beyond the colon or rectum.
Adjuvant Chemotherapy: This is given after surgery to eliminate any remaining cancer cells and reduce the risk of recurrence. Neoadjuvant Chemotherapy: This is given before surgery to shrink the tumor and make it easier to remove. Palliative Chemotherapy: This is given to control the growth of advanced cancer and relieve symptoms.
Types of Chemotherapy Drugs Used for Colorectal Cancer
Several chemotherapy drugs are commonly used to treat colorectal cancer. The specific drugs used will depend on the stage of the cancer, the patient's overall health, and other factors. Some common chemotherapy drugs include:
5-Fluorouracil (5-FU): This is a classic chemotherapy drug that has been used for many years. It works by interfering with the synthesis of DNA and RNA, which are essential for cell growth. Capecitabine (Xeloda): This is an oral chemotherapy drug that is converted into 5-FU in the body. Oxaliplatin (Eloxatin): This is a platinum-based chemotherapy drug that damages DNA. It is often used in combination with 5-FU or capecitabine. Irinotecan (Camptosar): This is a topoisomerase inhibitor that interferes with DNA replication. Trifluridine/Tipiracil (Lonsurf): This combination drug is used for advanced colorectal cancer that has stopped responding to other treatments.
How Chemotherapy is Administered
Chemotherapy is typically administered intravenously (IV) through a vein. The treatment schedule will vary depending on the specific drugs used and the patient's individual needs. Some patients may receive chemotherapy in cycles, with periods of treatment followed by periods of rest. This allows the body to recover from the side effects of chemotherapy. Chemotherapy can be administered in a hospital, clinic, or even at home.
