Larynx Cancer (cont.)
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.
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?
