Different types of treatment are available for patients with oropharyngeal cancer. Some treatments are standard (the currently used treatment), and some are being tested in clinical trials.
Two types of standard treatment are used:
Surgery (removing the cancer in an operation) is a common treatment of all stages of oropharyngeal cancer. A doctor may remove the cancer and some of the healthy tissue around the cancer. Even if the doctor removes all the cancer that can be seen at the time of the surgery, some patients may be given chemotherapy or radiation therapy after surgery to kill any cancer cells that are left. Treatment given after the surgery, to lower the risk of recurrence of cancer, is called adjuvant therapy.
is a cancer treatment that uses high-energy x-rays or other types of radiation to kill cancer cells or keep them from growing. There are two types of radiation therapy. External radiation therapy uses a machine outside the body to send radiation toward the cancer. Internal radiation therapy uses a radioactive substance sealed in needles, seeds, wires, or catheters that are placed directly into or near the cancer. The way the radiation therapy is given depends on the type and stage of the cancer being treated. Fractionated radiation therapy divides the total dose of radiation therapy into several smaller, equal doses given over several days.
Radiation therapy may be more effective in patients who have stopped smoking before beginning treatment.
Radiation therapy to the thyroid or pituitary gland increases the risk of hypothyroidism (too little thyroid hormone). Thyroid function tests should be done before and after treatment.
is a cancer treatment that uses drugs to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. When chemotherapy is taken by mouth or injected into a vein or muscle, the drugs enter the bloodstream and can reach cancer cells throughout the body (systemic chemotherapy). When chemotherapy is placed directly into the spinal column, an organ, or a body cavity such as the abdomen, the drugs mainly affect cancer cells in those areas (regional chemotherapy). The way the chemotherapy is given depends on the type and stage of the cancer being treated.
A treatment clinical trial is a research study meant to help improve current treatments or obtain information on new treatments for patients with cancer. When clinical trials show that a new treatment is better than the standard treatment, the new treatment may become the standard treatment. Patients may want to think about taking part in a clinical trial. Some clinical trials are open only to patients who have not started treatment.
New types of treatment are being tested in clinical trials.
Radiosensitizers are drugs that make tumor cells more sensitive to radiation therapy. Combining radiation therapy with radiosensitizers may kill more tumor cells.
Hyperthermia therapy is a treatment in which body tissue is exposed to increased temperature to damage and kill cancer cells or to make cancer cells more sensitive to the effects of radiation and certain anticancer drugs.
Some of the tests that were done to diagnose the cancer or to find out the stage of the cancer may be repeated. Some tests will be repeated in order to see how well the treatment is working.
Decisions about whether to continue, change, or stop treatment may be based on the results of these tests. This is sometimes called re-staging.
Some of the tests will continue to be done from time to time after treatment has ended. The results of these tests can show if your condition has changed or if the cancer has recurred (come back). These tests are sometimes called follow-up tests or check-ups.
After treatment for oropharyngeal cancer, frequent and careful follow-up is important because of the risk of developing a second cancer in the head or neck.
