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.
Signs & Symptoms
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
There are three types of standard treatment. Your OHC doctor will help you determine the best care plan for you.
- Surgery (removing the cancer in an operation) is a common treatment for all stages of hypopharyngeal cancer. The following surgical procedures may be used:
- Laryngopharyngectomy: Surgery to remove the larynx (voice box) and part of the pharynx (throat)
- Partial laryngopharyngectomy: Surgery to remove part of the larynx and part of the pharynx. A partial laryngopharyngectomy prevents loss of the voice
- Neck dissection: Surgery to remove lymph nodes and other tissues in the neck.
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 or keep them from growing. The way the radiation therapy is given depends on the type and stage of the cancer being treated. External radiation therapy is used to treat hypopharyngeal cancer.
Radiation therapy may work better 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. A blood test to check the thyroid hormone level in the body may be done before and after therapy to make sure the thyroid gland 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. Chemotherapy may be used to shrink the tumor before surgery or radiation therapy. This is called neoadjuvant chemotherapy.
