Diagnosis of Laryngeal Cancer
UT Southwestern’s experienced cancer specialists conduct a thorough evaluation, which includes a:
- Physical exam
- Discussion of personal and family medical history
- Discussion of symptoms and risk factors
To confirm a diagnosis, our doctors might recommend one or more tests, such as:
- Laryngoscopy: We sometimes use a scope (a thin, flexible tube with a lighted camera), which is inserted through the nose for a closer look into the throat.
- Videostroboscopy: Similar to a laryngoscopy, this test uses a scope with a video camera to record the larynx as the patient produces various sounds. We use videostroboscopy to view vibration abnormalities that can help detect cancer and determine the size and location of a tumor.
- Barium swallow: The patient swallows liquid barium, a substance that shows up on X-rays, and then X-rays are taken. Barium swallows can show abnormalities in the throat and evaluate swallowing.
- Computed tomography (CT) scan: CT uses specialized X-rays with or without a contrast agent to produce cross-sectional 3D images of the throat.
- Magnetic resonance imaging (MRI) scan: MRI uses radio waves and a strong magnet, with or without a contrast agent, to produce detailed images of the throat. MRI can also show whether cancer has spread to lymph nodes in the neck.
- Positron emission tomography (PET)/CT scan: Using small amounts of radioactive materials and a special camera, PET scans produce highly detailed images that can detect cancerous cells. At UT Southwestern, we use combined PET and CT scanning equipment to produce enhanced images that can help detect abnormal tissue that might be cancerous. PET scanning shows bodily functions such as blood flow and sugar metabolism, and CT scans provide detailed anatomical information for organs, bones, soft tissue, and blood vessels.
- Biopsy: Our doctors take a small tissue sample that a pathologist analyzes under a microscope for the presence of cancer. We perform biopsies using a needle or during a laryngoscopy, using a special tool on the scope.
Treatment for Laryngeal Cancer
Treatment options vary based on the stage of cancer and its size, location, and whether it has spread. Our doctors also work to preserve the larynx whenever possible. The most common treatments for laryngeal cancer are surgery and radiation therapy.
We use the following treatment options for laryngeal cancer, sometimes in combination:
Surgery: Patients with early-stage laryngeal cancer might need only surgery, whereas advanced cancers might require more comprehensive treatments given after performing surgery, known as adjuvant therapy. Depending on the extent of the cancer, surgical options include:
- Cordectomy to remove all or part of the vocal cords
- Partial laryngectomy to remove part of the larynx, which can preserve the ability to talk
- Total laryngectomy to remove the entire larynx and create a new opening for breathing, requiring patients to learn a new way to speak
- Thyroidectomy to remove all or part of the thyroid gland, if cancer has spread there
- Neck dissection to remove one or more lymph nodes or other tissues in the neck, if cancer has spread there
Radiation therapy: Our doctors use radiation, treatment with high-energy waves such as X-rays or gamma rays, to treat cancer. Radiation or surgery is usually the first treatment option for laryngeal cancer, and these therapies can treat and sometimes definitively cure it. Radiation therapy can destroy cancer cells left after surgery, and it can also treat inoperable tumors.
Chemotherapy: Anticancer medications work to destroy cancer cells and prevent them from spreading. Sometimes we use chemotherapy after radiation therapy or surgery to destroy as many cancer cells as possible. Chemotherapy can also treat laryngeal cancer that has spread to other areas of the body (metastatic) or cancer that comes back after treatment (recurrent).
Chemoradiation: Chemotherapy given at the same time as radiation therapy is known as chemoradiation. We use it whenever possible to help patients avoid a laryngectomy (removal of the larynx) and preserve the voice and swallowing ability.
Immunotherapy: This type of medication enhances the immune system’s natural ability to destroy cancer cells. Sometimes we use chemoradiation as adjuvant therapy after performing surgery or radiation or for metastatic,or recurrent cancer.
Targeted therapy: Certain anticancer medications target a specific characteristic of a cancer cell, which can be detected through specialized testing. People whose cancers have these characteristics can be treated with targeted therapy, usually in combination with radiation or chemotherapy. Sometimes we use targeted therapy as adjuvant therapy after performing surgery or radiation or for metastatic or recurrent cancer.
Reconstructive surgery: Patients with advanced laryngeal cancer might need reconstruction after cancer surgery. Our plastic surgery and ENT experts work together to restore swallowing and other oral functions for a more natural appearance of the throat and neck.
For patients who are having radiation therapy for laryngeal cancer, we recommend having any necessary dental work done before treatment. Radiation treatment slows healing and can cause other side effects. Learn more about cancer and transplant dental care.
