Cancer of the Anus Treatment
The treatment for anal cancer depends on whether the cancer has spread to tissue around the anus. A person with anal cancer may undergo surgery to remove a small tumor, while chemotherapy or radiation therapy is used to treat tumors that have spread beyond the anus. Chemotherapy drugs kill rapidly growing cancer cells. Radiation therapy uses x-ray beams to destroy cancer cells. A course of radiation therapy and chemotherapy may require weeks or months.
A person with a large anal cancer tumor may require surgery to remove the entire anus. In this case, the surgeon connects the end of the intestine to the abdominal wall, forming a colostomy. Stool passes through the colostomy, and is collected in a bag that is attached to the abdomen.
Treatment for anal cancer may include:
- Surgery for anal cancer:
- Focuses on removal of tumor and preservation of bowel function
- Approach depends on cancer stage (extent of spread)
- Chemotherapy for anal cancer:
- The administration of medicines that kill cancer cells.
- Fluorouracil (5-FU, Fluorouracil, Adrucil)
- Vincristine (Vincasar PFS, Oncovin)
- Leucovorin (Wellcovorin)
- Irinotecan (Camptosar, Camptothecin-11, CPT-11)
- Oxaliplatin (Eloxatin)
- Cetuximab (Erbitux)
- Bevacizumab (Avastin)
- Panitumumab (Vectibix)
- Radiation therapy for anal cancer:
- Exposing cancer cells to radiation can kill them.
- May also be delivered in the operating room during surgery
