Hypopharyngeal cancer is a disease in which malignant (cancer) cells form in the tissues of the hypopharynx.
The hypopharynx is the bottom part of the pharynx (throat). The pharynx is a hollow tube about 5 inches long that starts behind the nose, goes down the neck, and ends at the top of the trachea (windpipe) and esophagus (the tube that goes from the throat to the stomach). Air and food pass through the pharynx on the way to the trachea or the esophagus. Anatomy of the pharynx (throat). The three parts of the pharynx are the nasopharynx, oropharynx, and hypopharynx.
Most hypopharyngeal cancers form in squamous cells, the thin, flat cells lining the inside of the hypopharynx. The hypopharynx has 3 different areas. Cancer may be found in 1 or more of these areas.
Hypopharyngeal cancer is a type of head and neck cancer.
Use of tobacco products and heavy drinking can affect the risk of developing hypopharyngeal cancer.
Anything that increases your risk of getting a disease is called a risk factor. Having a risk factor does not mean that you will get cancer; not having risk factors doesn't mean that you will not get cancer. Talk with your doctor if you think you may be at risk. Risk factors include the following:
Signs and symptoms of hypopharyngeal cancer include a sore throat and ear pain.
These and other signs and symptoms may be caused by hypopharyngeal cancer or by other conditions. Check with your doctor if you have any of the following:
Tests that examine the throat and neck are used to help detect (find) and diagnose hypopharyngeal cancer.
The following tests and procedures may be used:
Certain factors affect prognosis (chance of recovery) and treatment options.
Prognosis (chance of recovery) depends on the following:
Treatment options depend on the following:
Patients who have had hypopharyngeal cancer are at an increased risk of developing a second cancer in the head or neck. Frequent and careful follow-up is important.
After hypopharyngeal cancer has been diagnosed, tests are done to find out if cancer cells have spread within the hypopharynx or to other parts of the body.
The process used to find out if cancer has spread within the hypopharynx or to other parts of the body is called staging. The information gathered from the staging process determines the stage of the disease. It is important to know the stage of the disease in order to plan treatment. The results of some of the tests used to diagnose hypopharyngeal cancer are often also used to stage the disease.
There are three ways that cancer spreads in the body.
Cancer can spread through tissue, the lymph system, and the blood:
Cancer may spread from where it began to other parts of the body.
When cancer spreads to another part of the body, it is called metastasis. Cancer cells break away from where they began (the primary tumor) and travel through the lymph system or blood.
The metastatic tumor is the same type of cancer as the primary tumor. For example, if hypopharyngeal cancer spreads to the lung, the cancer cells in the lung are actually hypopharyngeal cancer cells. The disease is metastatic hypopharyngeal cancer, not lung cancer.
The following stages are used for hypopharyngeal cancer:
Stage 0 (Carcinoma in Situ)
In stage 0, abnormal cells are found in the lining of the hypopharynx. These abnormal cells may become cancer and spread into nearby normal tissue. Stage 0 is also called carcinoma in situ.
Pea, peanut, walnut, and lime show tumor sizes.
In stage I, cancer has formed in one area of the hypopharynx only and/or the tumor is 2 centimeters or smaller.
In stage II, the tumor is either:
In stage III, the tumor:
Stage IV is divided into stage IVA, IVB, and IVC as follows:
Recurrent hypopharyngeal cancer is cancer that has recurred (come back) after it has been treated. The cancer may come back in the hypopharynx or in other parts of the body.
There are different types of treatment for patients with hypopharyngeal cancer.
Different types of treatment are available for patients with hypopharyngeal cancer. Some treatments are standard (the currently used treatment), and some are being tested in clinical trials. 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.
Three types of standard treatment are used:
Surgery (removing the cancer in an operation) is a common treatment for all stages of hypopharyngeal cancer. The following surgical procedures may be used:
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 that the cancer will come back, is called adjuvant therapy.
Radiation therapy is a cancer treatment that uses high-energy x-rays or other types of radiation to kill cancer cells. 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.
Radiation therapy may be more effective in patients who have stopped smoking before beginning treatment. External radiation therapy to the thyroid or the pituitary gland may change the way the thyroid gland works. The thyroid gland may be tested before and after therapy to make sure it is working properly.
Chemotherapy is a cancer treatment that uses drugs to stop the growth of cancer cells, either by killing the cells or by stopping the cells 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 cerebrospinal fluid, 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.
Chemotherapy may be used to shrink the tumor before surgery or radiation therapy. This is called neoadjuvant chemotherapy.
See Drugs Approved for Head and Neck Cancer for more information. (Hypopharyngeal cancer is a type of head and neck cancer.)
New types of treatment are being tested in clinical trials.
Information about clinical trials is available from the NCI Web site.
Patients may want to think about taking part in a clinical trial.
For some patients, taking part in a clinical trial may be the best treatment choice. Clinical trials are part of the cancer research process. Clinical trials are done to find out if new cancer treatments are safe and effective or better than the standard treatment.
Many of today's standard treatments for cancer are based on earlier clinical trials. Patients who take part in a clinical trial may receive the standard treatment or be among the first to receive a new treatment.
Patients who take part in clinical trials also help improve the way cancer will be treated in the future. Even when clinical trials do not lead to effective new treatments, they often answer important questions and help move research forward.
Patients can enter clinical trials before, during, or after starting their cancer treatment.
Some clinical trials only include patients who have not yet received treatment. Other trials test treatments for patients whose cancer has not gotten better. There are also clinical trials that test new ways to stop cancer from recurring (coming back) or reduce the side effects of cancer treatment.
Clinical trials are taking place in many parts of the country. See the Treatment Options section that follows for links to current treatment clinical trials. These have been retrieved from NCI's listing of clinical trials.
Follow-up tests may be needed.
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.
For hypopharyngeal cancer, follow-up to check for recurrence should include careful head and neck exams once a month in the first year after treatment ends, every 2 months in the second year, every 3 months in the third year, and every 6 months thereafter.

The PDQ cancer information summaries are reviewed regularly and updated as new information becomes available. This section describes the latest changes made to this summary as of the date above.
Editorial changes were made to this summary.
Physician Data Query (PDQ) is the National Cancer Institute's (NCI's) comprehensive cancer information database. The PDQ database contains summaries of the latest published information on cancer prevention, detection, genetics, treatment, supportive care, and complementary and alternative medicine. Most summaries come in two versions. The health professional versions have detailed information written in technical language. The patient versions are written in easy-to-understand, nontechnical language. Both versions have cancer information that is accurate and up to date and most versions are also available in Spanish.
PDQ is a service of the NCI. The NCI is part of the National Institutes of Health (NIH). NIH is the federal government's center of biomedical research. The PDQ summaries are based on an independent review of the medical literature. They are not policy statements of the NCI or the NIH.
Purpose of This Summary
This PDQ cancer information summary has current information about the treatment of hypopharyngeal cancer. It is meant to inform and help patients, families, and caregivers. It does not give formal guidelines or recommendations for making decisions about health care.
Reviewers and Updates
Editorial Boards write the PDQ cancer information summaries and keep them up to date. These Boards are made up of experts in cancer treatment and other specialties related to cancer. The summaries are reviewed regularly and changes are made when there is new information. The date on each summary ("Date Last Modified") is the date of the most recent change.
The information in this patient summary was taken from the health professional version, which is reviewed regularly and updated as needed, by the PDQ Adult Treatment Editorial Board.
Clinical Trial Information
A clinical trial is a study to answer a scientific question, such as whether one treatment is better than another. Trials are based on past studies and what has been learned in the laboratory. Each trial answers certain scientific questions in order to find new and better ways to help cancer patients. During treatment clinical trials, information is collected about the effects of a new treatment and how well it works. If a clinical trial shows that a new treatment is better than one currently being used, the new treatment may become "standard." 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.
Clinical trials are listed in PDQ and can be found online at NCI's Web site. Many cancer doctors who take part in clinical trials are also listed in PDQ. For more information, call the Cancer Information Service 1-800-4-CANCER (1-800-422-6237).
