Laryngeal Cancer Treatment (PDQ®): Treatment - Patient Information [NCI] - Treatment Option Overview

There are different types of treatment for patients with laryngeal cancer.

Different types of treatment are available for patients with laryngeal 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.

General Information About Langerhans Cell Histiocytosis (LCH)

The histiocytic diseases in children and adults include three major classes of disorders. Only Langerhans cell histiocytosis (LCH), a dendritic cell disorder, is discussed in detail in this summary. Erdheim-Chester disease (primarily found in adults) and juvenile xanthogranuloma (diagnosed in children and adults) are macrophage disorders. Other disorders of the macrophage/monocytoid lineages include Rosai-Dorfman disease and hemophagocytic lymphohistiocytosis. Malignant disorders include malignant...

Three types of standard treatment are used:

Radiation 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 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. The doctor may test the thyroid gland before and after therapy to make sure it is working properly.

Hyperfractionated radiation therapy and new types of radiation therapy are being studied in the treatment of laryngeal cancer.


Surgery (removing the cancer in an operation) is a common treatment for all stages of laryngeal cancer. The following surgical procedures may be used:

  • Cordectomy: Surgery to remove the vocal cords only.
  • Supraglottic laryngectomy: Surgery to remove the supraglottis only.
  • Hemilaryngectomy: Surgery to remove half of the larynx (voice box). A hemilaryngectomy saves the voice.
  • Partial laryngectomy: Surgery to remove part of the larynx (voice box). A partial laryngectomy helps keep the patient's ability to talk.
  • Total laryngectomy: Surgery to remove the whole larynx. During this operation, a hole is made in the front of the neck to allow the patient to breathe. This is called a tracheostomy.
  • Thyroidectomy: The removal of all or part of the thyroid gland.
  • Laser surgery: A surgical procedure that uses a laser beam (a narrow beam of intense light) as a knife to make bloodless cuts in tissue or to remove a surface lesion such as a tumor.
