General Information About Hypopharyngeal Cancer
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.
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:
- Smoking tobacco.
- Chewing tobacco.
- Heavy alcohol use.
- Eating a diet without enough nutrients.
- Having Plummer-Vinson syndrome.
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:
- A sore throat that does not go away.
- Ear pain.
- A lump in the neck.
- Painful or difficult swallowing.
- A change in voice.
Tests that examine the throat and neck are used to help diagnose hypopharyngeal cancer and find out whether the cancer has spread.
The following tests and procedures may be used:
- Physical exam and health history: An exam of the body to check general signs of health, including checking for signs of disease, such as lumps or anything else that seems unusual. A history of the patient’s health habits and past illnesses and treatments will also be taken.
- Physical exam of the throat: An exam in which the doctor feels for swollen lymph nodes in the neck and looks down the throat with a small, long-handled mirror to check for abnormal areas.
- Neurological exam: A series of questions and tests to check the brain, spinal cord, and nerve function. The exam checks a person’s mental status, coordination, and ability to walk normally, and how well the muscles, senses, and reflexes work. This may also be called a neuro exam or a neurologic exam.
- CT scan (CAT scan): A procedure that makes a series of detailed pictures of areas inside the body, such as the head, neck, chest, and lymph nodes, taken from different angles. The pictures are made by a computer linked to an x-ray machine. A dye may be injected into a vein or swallowed to help the organs or tissues show up more clearly. This procedure is also called computed tomography, computerized tomography, or computerized axial tomography.
- PET scan (positron emission tomography scan): A procedure to find malignant tumor cells in the body. A small amount of radioactive glucose (sugar) is injected into a vein. The PET scanner rotates around the body and makes a picture of where glucose is being used in the body. Malignant tumor cells show up brighter in the picture because they are more active and take up more glucose than normal cells do. A PET scan and CT scan may be done at the same time. This is called a PET-CT.
- MRI (magnetic resonance imaging): A procedure that uses a magnet, radio waves, and a computer to make a series of detailed pictures of areas inside the body, such as the head, neck, chest, and lymph nodes. This procedure is also called nuclear magnetic resonance imaging (NMRI).
- Endoscopy: A procedure used to look at areas in the throat that cannot be seen with a mirror during the physical exam of the throat. An endoscope (a thin, lighted tube) is inserted through the nose or mouth to check the throat for anything that seems unusual. Tissue samples may be taken for biopsy.
- Biopsy: The removal of cells or tissues so they can be viewed under a microscope to check for signs of cancer.
- Bone scan: A procedure to check if there are rapidly dividing cells, such as cancer cells, in the bone. A very small amount of radioactive material is injected into a vein and travels through the bloodstream. The radioactive material collects in the bones with cancer and is detected by a scanner.
- Barium esophagogram: An x-ray of the esophagus. The patient drinks a liquid that contains barium (a silver-white metallic compound). The liquid coats the esophagus and x-rays are taken.
- Esophagoscopy: A procedure to look inside the esophagus to check for abnormal areas. An esophagoscope (a thin, lighted tube) is inserted through the mouth or nose and down the throat into the esophagus. Tissue samples may be taken for biopsy.
- Bronchoscopy: A procedure to look inside the trachea and large airways in the lung for abnormal areas. A bronchoscope (a thin, lighted tube) is inserted through the nose or mouth into the trachea and lungs. Tissue samples may be taken for biopsy.
Certain factors affect prognosis (chance of recovery) and treatment options.
Prognosis depends on the following:
- The stage of the cancer (whether it affects part of the hypopharynx, involves the whole hypopharynx, or has spread to other places in the body). Hypopharyngeal cancer is usually detected in later stages because early signs and symptoms rarely occur.
- The patient's age, gender, and general health.
- The location of the cancer.
- Whether the patient smokes during radiation therapy.
Treatment options depend on the following:
- The stage of the cancer.
- Keeping the patient's ability to talk, eat, and breathe as normal as possible.
- The patient's general health.
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.
