Laryngeal Cancer

The Larynx

The larynx is an organ at the front of your neck. It is also called the voice box. It is about 2 inches long and 2 inches wide. It is above the windpipe (trachea). Below and behind the larynx is the esophagus.

The larynx has two bands of muscle that form the vocal cords. The cartilage at the front of the larynx is sometimes called the Adam’s apple.

The larynx has three main parts:

The top part of the larynx is the supraglottis.
The glottis is in the middle. Your vocal cords are in the glottis.
The subglottis is at the bottom. The subglottis connects to the windpipe.

Illustration shows the main parts of the larynx (supraglottis, glottis, subglottis, Adam's apple) and trachea.

This picture shows the main parts of the larynx.

This picture shows how the larynx looks from above. It is what the doctor can see with a mirror.

The larynx plays a role in breathing, swallowing, and talking. The larynx acts like a valve over the windpipe. The valve opens and closes to allow breathing, swallowing, and speaking:

Breathing: When you breathe, the vocal cords relax and open. When you hold your breath, the vocal cords shut tightly.
Swallowing: The larynx protects the windpipe. When you swallow, a flap called the epiglottis covers the opening of your larynx to keep food out of your lungs. The food passes through the esophagus on its way from your mouth to your stomach.
Talking: The larynx produces the sound of your voice. When you talk, your vocal cords tighten and move closer together. Air from your lungs is forced between them and makes them vibrate. This makes the sound of your voice. Your tongue, lips, and teeth form this sound into words.

What Is Cancer?

Cancer begins in cells, the building blocks that make up tissues. Tissues make up the organs of your body. Normally, cells grow and divide to form new cells as your body needs them. When cells grow old, they die, and new cells take their place.

Sometimes this orderly process goes wrong. New cells form when the body does not need them, and old cells do not die when they should. These extra cells can form a mass of tissue called a growth or tumor. Growths on the larynx also may be called nodules or polyps. Not all growths are cancer. Growths can be benign or malignant:

Benign growths are not cancer:

They are rarely life-threatening.
Usually, benign tumors can be removed, and they seldom grow back.
Cells from benign tumors do not spread to tissues around them or to other parts of the body.

Malignant growths are cancer:

They are generally more serious and may be life-threatening.
Malignant tumors usually can be removed, but they can grow back.
Cells from malignant tumors invade and damage nearby tissues and organs. Also, cancer cells can break away from a malignant tumor and enter the bloodstream or lymphatic system. That is how cancer cells spread from the original cancer (the primary tumor) to form new tumors in other organs. The spread of cancer is called metastasis. Different types of cancer tend to spread to different parts of the body.

Cancer of the larynx also may be called laryngeal cancer. It can develop in any part of the larynx. Most cancers of the larynx begin in the glottis. The inner walls of the larynx are lined with cells called squamous cells. Almost all laryngeal cancers begin in these cells. These cancers are called squamous cell carcinomas.

If cancer of the larynx spreads (metastasizes), the cancer cells often spread to nearby lymph nodes in the neck. The cancer cells can also spread to the back of the tongue, other parts of the throat and neck, the lungs, and other parts of the body. When this happens, the new tumor has the same kind of abnormal cells as the primary tumor in the larynx. For example, if cancer of the larynx spreads to the lungs, the cancer cells in the lungs are actually laryngeal cancer cells. The disease is called metastatic cancer of the larynx, not lung cancer. It is treated as cancer of the larynx, not lung cancer. Doctors sometimes call the new tumor “distant” disease.

Cancer of the Larynx: Who’s at Risk?

No one knows the exact causes of cancer of the larynx. Doctors cannot explain why one person gets this disease and another does not. We do know that cancer is not contagious. You cannot “catch” cancer from another person.

People with certain risk factors are more likely to get cancer of the larynx. A risk factor is anything that increases your chance of developing this disease.

Studies have found the following risk factors:

Age. Cancer of the larynx occurs most often in people over the age of 55.
Gender. Men are four times more likely than women to get cancer of the larynx.
Race. African Americans are more likely than whites to be diagnosed with cancer of the larynx.
Smoking. Smokers are far more likely than nonsmokers to get cancer of the larynx. The risk is even higher for smokers who drink alcohol heavily.
People who stop smoking can greatly decrease their risk of cancer of the larynx, as well as cancer of the lung, mouth, pancreas, bladder, and esophagus. Also, quitting smoking reduces the chance that someone with cancer of the larynx will get a second cancer in the head and neck region. (Cancer of the larynx is part of a group of cancers called head and neck cancers.)
Alcohol. People who drink alcohol are more likely to develop laryngeal cancer than people who don’t drink. The risk increases with the amount of alcohol that is consumed. The risk also increases if the person drinks alcohol and also smokes tobacco.
A personal history of head and neck cancer. Almost one in four people who have had head and neck cancer will develop a second primary head and neck cancer.
Occupation. Workers exposed to sulfuric acid mist or nickel have an increased risk of laryngeal cancer. Also, working with asbestos can increase the risk of this disease. Asbestos workers should follow work and safety rules to avoid inhaling asbestos fibers.

Other studies suggest that having certain viruses or a diet low in vitamin A may increase the chance of getting cancer of the larynx. Another risk factor is having gastroesophageal reflux disease (GERD), which causes stomach acid to flow up into the esophagus.

Most people who have these risk factors do not get cancer of the larynx. If you are concerned about your chance of getting cancer of the larynx, you should discuss this concern with your health care provider. Your health care provider may suggest ways to reduce your risk and can plan an appropriate schedule for checkups.

Symptoms

The symptoms of cancer of the larynx depend mainly on the size of the tumor and where it is in the larynx. Symptoms may include the following:

Hoarseness or other voice changes
A lump in the neck
A sore throat or feeling that something is stuck in your throat
A cough that does not go away
Problems breathing
Bad breath
An earache
Weight loss

These symptoms may be caused by cancer or by other, less serious problems. Only a doctor can tell for sure.

Diagnosis

If you have symptoms of cancer of the larynx, the doctor may do some or all of the following exams:

Physical exam. The doctor will feel your neck and check your thyroid, larynx, and lymph nodes for abnormal lumps or swelling. To see your throat, the doctor may press down on your tongue.
Indirect laryngoscopy. The doctor looks down your throat using a small, long-handled mirror to check for abnormal areas and to see if your vocal cords move as they should. This test does not hurt. The doctor may spray a local anesthesia in your throat to keep you from gagging. This exam is done in the doctor's office.
Direct laryngoscopy. The doctor inserts a thin, lighted tube called a laryngoscope through your nose or mouth. As the tube goes down your throat, the doctor can look at areas that cannot be seen with a mirror. A local anesthetic eases discomfort and prevents gagging. You may also receive a mild sedative to help you relax. Sometimes the doctor uses general anesthesia to put a person to sleep. This exam may be done in a doctor's office, an outpatient clinic, or a hospital.
CT scan. An x-ray machine linked to a computer takes a series of detailed pictures of the neck area. You may receive an injection of a special dye so your larynx shows up clearly in the pictures. From the CT scan, the doctor may see tumors in your larynx or elsewhere in your neck.
Biopsy. If an exam shows an abnormal area, the doctor may remove a small sample of tissue. Removing tissue to look for cancer cells is called a biopsy. For a biopsy, you receive local or general anesthesia, and the doctor removes tissue samples through a laryngoscope. A pathologist then looks at the tissue under a microscope to check for cancer cells. A biopsy is the only sure way to know if a tumor is cancerous.

If you need a biopsy, you may want to ask the doctor the following questions:

What kind of biopsy will I have? Why?
How long will it take? Will I be awake? Will it hurt?
How soon will I know the results?
Are there any risks? What are the chances of infection or bleeding after the biopsy?
If I do have cancer, who will talk with me about treatment? When?

Staging

To plan the best treatment, your doctor needs to know the stage, or extent, of your disease. Staging is a careful attempt to learn whether the cancer has spread and, if so, to what parts of the body. The doctor may use x-rays, CT scans, or magnetic resonance imaging to find out whether the cancer has spread to lymph nodes, other areas in your neck, or distant sites.

Treatment

People with cancer of the larynx often want to take an active part in making decisions about their medical care. It is natural to want to learn all you can about your disease and treatment choices. However, shock and stress after a diagnosis of cancer can make it hard to remember what you want to ask the doctor. Here are some ideas that might help:

Make a list of questions.
Take notes at the appointment.
Ask the doctor if you may use a tape recorder during the appointment.
Ask a family member or friend to come to the appointment with you.

Your doctor may refer you to a specialist who treats cancer of the larynx, such as a surgeon, otolaryngologist (an ear, nose, and throat doctor), radiation oncologist, or medical oncologist. You can also ask your doctor for a referral. Treatment usually begins within a few weeks of the diagnosis. Usually, there is time to talk to your doctor about treatment choices, get a second opinion, and learn more about the disease before making a treatment decision.

Getting a Second Opinion

Before starting treatment, you might want a second opinion about your diagnosis and treatment plan. Some insurance companies require a second opinion; others may cover a second opinion if you or your doctor requests it. There are a number of ways to find a doctor for a second opinion:

Your doctor may refer you or you may ask for a referral to one or more specialists. At cancer centers, several specialists often work together as a team. The team may include a surgeon, radiation oncologist, medical oncologist, speech pathologist, and nutritionist. At some cancer centers, you may be able to see them all on the same day.
The Cancer Information Service, at 1-800-4-CANCER, can tell you about treatment centers near you.
A local medical society, a nearby hospital, or a medical school can often provide the names of specialists in your area.

Preparing for Treatment

The doctor can describe your treatment choices and the results you can expect for each treatment option. You will want to consider how treatment may change the way you look, breathe, and talk. You and your doctor can work together to develop a treatment plan that meets your needs and personal values.

The choice of treatment depends on a number of factors, including your general health, where in the larynx the cancer began, the size of the tumor, and whether the cancer has spread.

If you smoke, a good way to prepare for treatment is to stop smoking. Studies show that treatment is more likely to be successful for people who don’t smoke. Your doctor or the Cancer Information Service (1-800-4-CANCER) may be able to suggest ways to help you stop smoking.

You may want to talk with the doctor about taking part in a clinical trial, a research study of new treatment methods. Clinical trials are an important option. Patients who join trials have the first chance to benefit from new treatments that have shown promise in earlier research. The section on “The Promise of Cancer Research” has more information about research in progress.

These are questions you may want to ask your doctor before treatment begins:

Where is my cancer and has it spread?
What are my treatment choices? Which do you recommend for me? Why?
What are the benefits of each treatment?
What are the risks and possible side effects of each treatment?
How will I look after treatment?
How will I speak after treatment? Will I need to work with a speech therapist?
Will I have problems eating?
Will I need to change my daily activities?
When can I return to work?
What is the treatment likely to cost? Is this treatment covered by my insurance plan?
Would a clinical trial (research study) be right for me? Can you help me find one?
How often will I need checkups?

You do not need to ask all your questions or understand all the answers at once. You will have many chances to ask the doctor and the rest of the health care team to explain things that are not clear and to ask for more information.

Methods of Treatment

Cancer of the larynx may be treated with radiation therapy, surgery, or chemotherapy. Some patients have a combination of therapies.

Radiation therapy (also called radiotherapy) uses high-energy x-rays to kill cancer cells. The rays are aimed at the tumor and the tissue around it. Radiation therapy is local therapy. It affects cells only in the treated area. Treatments are usually given 5 days a week for 5 to 8 weeks.

Laryngeal cancer may be treated with radiation therapy alone or in combination with surgery or chemotherapy:

Radiation therapy alone: Radiation therapy is used alone for small tumors or for patients who cannot have surgery.
Radiation therapy combined with surgery: Radiation therapy may be used to shrink a large tumor before surgery or to destroy cancer cells that may remain in the area after surgery. If a tumor grows back after surgery, it is often treated with radiation.
Radiation therapy combined with chemotherapy: Radiation therapy may be used before, during, or after chemotherapy.

After radiation therapy, some people need feeding tubes placed into the abdomen. The feeding tube is usually temporary.

These are questions you may want to ask your doctor before having radiation therapy:

Why do I need this treatment?
What are the risks and side effects of this treatment?
Are there any long-term effects?
Should I see my dentist before I start treatment?
When will the treatments begin? When will they end?
How will I feel during therapy?
What can I do to take care of myself during therapy?
Can I continue my normal activities?
How will my neck look afterward?
What is the chance that the tumor will come back?
How often will I need checkups?

Surgery is an operation in which a doctor removes the cancer using a scalpel or laser while the patient is asleep. When patients need surgery, the type of operation depends mainly on the size and exact location of the tumor.

Surgery for Cancer of the Larynx

There are several types of laryngectomy (surgery to remove part or all of the larynx):

Total laryngectomy: The surgeon removes the entire larynx.
Partial laryngectomy (hemilaryngectomy): The surgeon removes part of the larynx.

Supraglottic laryngectomy: The surgeon takes out the supraglottis, the top part of the larynx.
Cordectomy: The surgeon removes one or both vocal cords.

Sometimes the surgeon also removes the lymph nodes in the neck. This is called lymph node dissection. The surgeon also may remove the thyroid.

During surgery for cancer of the larynx, the surgeon may need to make a stoma. (This surgery is called a tracheostomy.) The stoma is a new airway through an opening in the front of the neck. Air enters and leaves the windpipe (trachea) and lungs through this opening. A tracheostomy tube, also called a trach (“trake”) tube, keeps the new airway open. For many patients, the stoma is temporary. It is needed only until the patient recovers from surgery. More information about stomas can be found in the “Living with a Stoma” section.

After surgery, some people may need a temporary feeding tube.

This picture shows the pathways for air and food after a total laryngectomy.

The stoma is the new opening into the trachea.

Here are some questions to ask the doctor before having surgery:

How will I feel after the operation?
Will I need a tracheostomy?
Will I need to learn how to take care of myself or my incision when I get home?
Where will the scars be? What will they look like?
Will surgery affect my ability to speak? If so, who will teach me how to speak in a new way?
When can I get back to my normal activities?

Chemotherapy is the use of drugs to kill cancer cells. Your doctor may suggest one drug or a combination of drugs. The drugs for cancer of the larynx are usually given by injection into the bloodstream. The drugs enter the bloodstream and travel throughout the body.

Chemotherapy is used to treat laryngeal cancer in several ways:

Before surgery or radiation therapy: In some cases, drugs are given to try to shrink a large tumor before surgery or radiation therapy.
After surgery or radiation therapy: Chemotherapy may be used after surgery or radiation therapy to kill any cancer cells that may be left. It also may be used for cancers that have spread.
Instead of surgery: Chemotherapy may be used with radiation therapy instead of surgery. The larynx is not removed and the voice is spared.

Chemotherapy may be given in an outpatient part of the hospital, at the doctor’s office, or at home. Rarely, a hospital stay may be needed.

These are questions you may want to ask your doctor before having chemotherapy:

Why do I need this treatment?
What will it do?
Will I have side effects? What can I do about them?
How long will I be on this treatment?
How often will I need checkups?

Side Effects of Cancer Treatment

Cancer treatments are very powerful. Treatments that remove or destroy cancer cells are likely to damage healthy cells, too. That's why treatments often cause side effects. This section describes some of the side effects of each kind of treatment.

Side effects may not be the same for each person, and they may even change from one treatment session to the next. Before treatment starts, your health care team will explain possible side effects and how they can be managed. It may help to know that although some side effects may not go away completely, most of them become less troubling.

It may also help to talk with other patients. A social worker, nurse, or other member of the medical team can set up a visit with someone who has had the same treatment.

The NCI provides helpful booklets about cancer treatments and coping with side effects, such as Radiation Therapy and You, Chemotherapy and You, and Eating Hints.

Radiation Therapy

People treated with radiation therapy may have some or all of these side effects:

Dry mouth. Drinking lots of fluids can help. Some patients find artificial saliva helpful. It comes in a spray or squeeze bottle.
Sore throat or mouth. Your health care provider may suggest special rinses to numb your throat and mouth and help relieve the soreness.
Delayed healing after dental care. Many doctors recommend having a dental exam and any needed dental work before radiation therapy.
Tooth decay. Good mouth care can help keep your teeth and gums healthy and can help you feel better. If it's hard to floss or brush your teeth in the usual way, you can try using gauze, a soft toothbrush, or a toothbrush that has a spongy tip instead of bristles. A mouthwash made with diluted peroxide, salt water, baking soda, or a combination can keep your mouth fresh and help protect your teeth from decay. It may also be helpful to use fluoride toothpaste or rinse.
Changes in sense of taste and smell. During radiation therapy, food may taste or smell different.
Fatigue. During radiation therapy, you may become very tired, especially in the later weeks of treatment. Resting is important, but doctors usually advise their patients to stay as active as they can.
Changes in voice quality. Your voice may be weak at the end of the day. It may also be affected by changes in the weather. Voice changes and the feeling of a lump in your throat may come from swelling in the larynx caused by the radiation. The doctor may suggest medicine to reduce this swelling.
Skin changes in treated area. The skin in the treated area may become red or dry. Good skin care is important at this time. Try to expose this area to the air but protect it from the sun. Avoid wearing clothes that rub, and do not shave the treated area. You should not put anything on your skin before radiation treatments. Also, you should never use lotion or cream without your doctor's advice.

Surgery

People who have surgery may have any of these side effects:

Pain. You may be uncomfortable for the first few days after surgery. However, medicine can usually control the pain. You should feel free to discuss pain relief with the doctor or nurse.
Low energy. It is common to feel tired or weak after surgery. The length of time it takes to recover from an operation is different for each patient.
Swelling in the throat. For a few days after surgery, you won’t be able to eat, drink, or swallow. At first, you will receive fluid through an intravenous (IV) tube placed into your arm. Within a day or two, you will get fluids and nutrition through a feeding tube (put in place during surgery) that goes through your nose and throat into your stomach. When the swelling goes away and the area begins to heal, the feeding tube will be removed. Swallowing may be difficult at first, and you may need the help of a nurse or speech pathologist. Soon you will be eating your regular diet.
If you need a feeding tube for longer than one week, you may get a tube that goes directly into the abdomen. Most patients slowly return to eating solid foods by mouth, but for a very few patients, the feeding tube may be permanent.
Increased mucus production. After the operation, the lungs and windpipe produce a lot of mucus, also called sputum. To remove it, the nurse applies gentle suction by placing a small plastic tube in the stoma. You will learn to cough and suction mucus through the stoma without the nurse's help.
Numbness, stiffness, or weakness. After a laryngectomy, parts of the neck and throat may be numb because nerves have been cut. Also, the shoulder, neck, and arm may be weak and stiff. You may need physical therapy to improve your strength and flexibility after surgery.
Changes in physical appearance. Your neck will be somewhat smaller, and it will have scars. Some patients find it helpful to wear clothing that covers the neck area.
Tracheostomy. Patients who have surgery will have a stoma. With most supraglottic and partial laryngectomies, the stoma is temporary. After a short recovery period, the tube can be removed, and the stoma closes up. You should then be able to breathe and talk in the usual way. In some people, however, the voice may be hoarse or weak.
After a total laryngectomy, the stoma is permanent. If you have a total laryngectomy, you will need to learn to speak in a new way. The section called “Learning to Speak Again” has more information.
More information about stomas may be found in the “Living with a Stoma” section.

Chemotherapy

The side effects of chemotherapy depend mainly on the specific drugs and the dose. In general, anticancer drugs affect cells that divide rapidly:

Blood cells: These cells fight infection, help your blood to clot, and carry oxygen to all parts of your body. If your blood cells are affected, you are more likely to get infections, may bruise or bleed easily, and may feel very weak and tired.
Cells in hair roots: Chemotherapy can lead to hair loss, but hair will grow back. However, the new hair may be different in color and texture.
Cells that line the digestive tract: Chemotherapy can cause poor appetite, nausea and vomiting, diarrhea, or mouth and lip sores. Many of these side effects can be controlled with new or improved drugs.

Nutrition

Some people who have had treatment for cancer of the larynx may lose their interest in food. Soreness and changes in smell and taste may make eating difficult. Yet good nutrition is important. Eating well means getting enough calories and protein to prevent weight loss, regain strength, and rebuild healthy tissues.

If eating is difficult because your mouth is dry from radiation therapy, you may want to try soft, bland foods moistened with sauces or gravies. Thick soups, puddings, and milkshakes often are easier to swallow. The nurse and the dietitian will help you choose the right foods.

After surgery or radiation therapy, some people need feeding tubes placed into the abdomen. Most people slowly return to a regular diet. Learning to swallow again may take some practice with the help of a nurse or speech pathologist. Some people find liquids easier to swallow; others do better with solid foods. You will find what works best for you.

Living with a Stoma

Learning to live with the changes brought about by cancer of the larynx is a special challenge. The medical team will make every effort to help you return to your normal routine as soon as possible.

If you have a stoma, you will need to learn how to care for it:

Before leaving the hospital, you will learn to remove and clean the trach tube, suction the trach, and care for the skin around the stoma.
If the air is too dry, as it may be in heated buildings in the winter, the tissues of the windpipe and lungs may produce extra mucus. Also, the skin around the stoma may get sore. Keeping the skin around the stoma clean and using a humidifier at home or at the office can lessen these problems.
It is very dangerous for water to get into the windpipe and lungs through the stoma. Wearing a special plastic stoma shield or holding a washcloth over the stoma keeps water out when showering or shaving. Other types of stoma covers—such as scarves, neckties, and specially made covers—help keep moisture in and around the stoma. They help filter smoke and dust from the air before it enters the stoma. They also catch any fluids that come out of the windpipe when you cough or sneeze. Many people choose to wear something over their stoma even after the area heals. Stoma covers can be attractive as well as useful.
When shaving, men should keep in mind that the neck may be numb for several months after surgery. To avoid nicks and cuts, it may be best to use an electric shaver until the numbness goes away.

People with stomas work in almost every type of business and can do nearly all of the things they did before. However, they cannot hold their breath, so straining and heavy lifting may be difficult. Also, swimming and water skiing are not possible without special instruction and equipment to keep water from entering the stoma.

Some people may feel self-conscious about the way they look and speak. They may be concerned about how other people feel about them. They may be concerned about how their sexual relationships may be affected. Many people find that talking about these concerns helps them. Counseling or support groups may also be helpful.

Learning To Speak Again

Talking is part of nearly everything we do, so it's natural to be scared if your voice box must be removed. Losing the ability to talk—even for a short time—is hard. Patients and their families and friends need understanding and support during this time.

Within a week or so after a partial laryngectomy, you will be able to talk in the usual way. After a total laryngectomy, however, you must learn to speak in a new way. A speech pathologist usually meets with you before surgery to explain the methods that can be used. In many cases, speech lessons start before you leave the hospital.

Looking Forward: The Speech and Swallowing Guidebook for People with Cancer of the Larynx or Tongue

Until you begin to talk again, it is important to have other ways to communicate. Here are some ideas that you may find helpful:

Keep pads of paper and pens or pencils in your pocket or purse.
Use a typewriter, computer, or other electronic device. Your words can be printed on paper, displayed on a screen, or produced in a male or female voice.
Carry a small dictionary or a picture book and point to the words you need.
Write notes on a "magic slate" (a toy with a plastic sheet that covers black wax; lifting the plastic erases the sheet).

The health care team can help patients learn new ways to speak. It takes practice and patience to learn techniques such as esophageal speech or tracheoesophageal puncture speech, and not everyone is successful. How quickly a person learns, how understandable the speech is, and how natural the new voice sounds depend on the extent of the surgery on the larynx.

Esophageal Speech

A speech pathologist can teach you how to force air into the top of your esophagus and then push it out again. The puff of air is like a burp. It vibrates the walls of the throat, making sound for the new voice. The tongue, lips, and teeth form words as the sound passes through the mouth.

This type of speech sounds low pitched and gruff, but it usually sounds more like a natural voice than speech made by a mechanical larynx. There is also no device to carry around, so your hands are free.

Foundations of Voice and Speech Rehabilitation Following Laryngeal Cancer

Tracheoesophageal Puncture

For tracheoesophageal puncture (TEP), the surgeon makes an opening between the trachea and the esophagus. The opening is made at the time of initial surgery or later. A small plastic or silicone valve fits into this opening. The valve keeps food out of the trachea. After TEP, patients can cover their stoma with a finger and force air into the esophagus through the valve. The air produces sound by making the walls of the throat vibrate. The sound is a lot like natural speech.

Mechanical Speech

You may choose to use a mechanical larynx while you learn esophageal or TEP speech or if you are unable to use these methods. The device may be powered by batteries (electrolarynx) or by air (pneumatic larynx).

Many different mechanical devices are available. The speech pathologist will help you choose the best device for your needs and abilities and will train you to use it.

One kind of electrolarynx looks like a small flashlight. It makes a humming sound. You hold the device against your neck, and the sound travels through your neck to your mouth. Another type of electrolarynx has a flexible plastic tube that carries sound into your mouth from a hand-held device. There are also devices that are built into a denture or retainer and can be worn inside your mouth and operated by a hand-held remote control.

A pneumatic larynx is held over the stoma and uses air from the lungs instead of batteries to make it vibrate. The sound it makes travels to the mouth through a plastic tube.

Followup Care

Followup care is important after treatment for cancer of the larynx. Regular checkups ensure that any changes in health are noted. Problems can be found and treated as soon as possible. The doctor will check closely to be sure that the cancer has not returned. Checkups include exams of the stoma, neck, and throat. From time to time, the doctor may do a complete physical exam and take x-rays. If you had radiation therapy or a partial laryngectomy, the doctor will also examine you with a laryngoscope.

Treatments for laryngeal cancer can affect the thyroid. A blood test can tell if the thyroid is making enough thyroid hormone. If the level is low, you may need to take thyroid hormone pills.

People who have laryngeal cancer have a chance of developing a new cancer in the mouth, throat, or other areas of the head and neck. This is especially true for those who are smokers or drink alcohol heavily. Most doctors strongly urge their patients to stop smoking and drinking to cut down the risk of a new cancer and other health problems.

The NCI has prepared a booklet for people who have completed their treatment to help answer questions about follow-up care and other concerns. Facing Forward: Life After Cancer Treatment provides tips for making the best use of medical visits. It describes the kinds of help people may need.

Support for People with Cancer of the Larynx

Living with a serious disease such as cancer is not easy. Some people find they need help coping with the emotional and practical aspects of their disease. Support groups can help. In these groups, people living with cancer get together to share what they have learned about coping with the disease and the effects of treatment. People interested in finding a support group may want to talk with their health care provider for suggestions.

People living with cancer may worry about caring for their families, keeping their jobs, or continuing daily activities. Concerns about tests, treatments, hospital stays, and medical bills are also common. Doctors, nurses, and other members of the health care team can answer questions about treatment, working, or other activities. Meeting with a social worker, counselor, or member of the clergy can be helpful for those who want to talk about their feelings or discuss their concerns. Often, a social worker can suggest resources for help with rehabilitation, emotional support, financial aid, transportation, or home care.

The Cancer Information Service (1-800-4-CANCER) can provide printed materials on coping, as well as information to help patients and their families locate programs and services.

The Promise of Cancer Research

Doctors all over the country are conducting many types of clinical trials. These are research studies in which people take part voluntarily. Studies include new ways to treat cancer of the larynx. Research already has led to advances, and researchers continue to search for more effective approaches.

People who join these studies have the first chance to benefit from treatments that have shown promise in earlier research. They also make an important contribution to medical science by helping doctors learn more about the disease. Although clinical trials may pose some risks, researchers take very careful steps to protect their patients.

People with laryngeal cancer are participating in several types of treatment studies:

Radiation therapy. Researchers are studying a new approach to radiation therapy. Patients receive radiation three times a day, 5 days a week, for just over 2 weeks, instead of once a day for 5 to 7 weeks.
Drugs that reduce side effects. Researchers are testing therapies that reduce the side effects of radiation therapy. They are testing drugs that may help patients maintain their weight or help lessen damage to the skin during radiation therapy.
Chemotherapy. Scientists are studying drugs that kill cancer cells. These drugs are used alone or in combination with radiation therapy to spare the larynx from surgery.
Biological therapy. Scientists are studying monoclonal antibodies that slow or stop the growth of cancer.

If you are interested in learning more about joining a clinical trial, you may want to talk with your doctor. You may want to read the NCI booklet Taking Part in Cancer Treatment Research Studies. It explains how clinical trials are carried out and explains their possible benefits and risks. NCI’s Web site includes a section on clinical trials. This section of the Web site provides general information about clinical trials. It also offers detailed information about specific ongoing studies of cancer of the larynx. The Cancer Information Service at 1-800-4-CANCER can answer questions and provide information from the NCI’s database of clinical trials.
