Treatments for stage 3 anal cancer
The following are treatment options for stage 3 anal cancer. Your healthcare team will suggest treatments based on your needs and work with you to develop a treatment plan.
Chemoradiation is the main treatment for stage 3 anal cancer. It combines chemotherapy with radiation therapy. The 2 treatments are given during the same time period. Some types of chemotherapy make radiation therapy more effective.
Chemoradiation is usually given as daily treatments of external beam radiation therapy for 5–6 weeks. The drugs most commonly given during this time period are 5-fluorouracil (5-FU, Adrucil) and mitomycin (Mutamycin). Sometimes capecitabine (Xeloda) is used instead of 5-fluorouracil.
Sometimes more treatment is needed if the chemoradiation didn’t destroy all the cancer cells. This may be called salvage therapy. It is usually chemotherapy alone or with radiation therapy. The chemotherapy drugs used most often in salvage therapy are 5-fluorouracil and cisplatin (Platinol AQ). When more radiation therapy is given, it’s called a radiation boost.
You may be offered surgery for stage 3 anal cancer if chemoradiation didn’t destroy all the cancer cells.
Abdominoperineal resection may be used to treat stage 3A or stage 3B anal cancer. This surgery removes the rectum, anus, anal sphincter and muscles around the anus.
Wide local excision may be used to remove a stage 3B anal cancer when there is only a small amount of cancer. This surgery removes the tumour along with some healthy tissue around it (called the surgical margin).
Inguinal lymph node dissection may be used to treat stage 3B anal cancer when it has spread to lymph nodes in the groin.
You may be asked if you want to join a clinical trial for anal cancer. Find out more about clinical trials.
Taking action against all cancers
The latest Canadian Cancer Statistics report found that of all newly diagnosed cancers in 2017, half are expected to be lung, colorectal, breast and prostate cancers. Learn what you can do to reduce the burden of cancer.
