General Information About Laryngeal Cancer
Laryngeal cancer is a disease in which malignant (cancer) cells
form in the tissues of the larynx.
The larynx (voice box)
is located just below the pharynx
(throat) in the neck. The larynx contains the vocal
cords, which vibrate and make sound when air is directed against
them. The sound echoes through the pharynx, mouth, and nose to make a person's
voice.
Most laryngeal cancers form in squamous cells, the thin, flat cells lining the inside of the larynx.
There are three main parts of the larynx:
- Supraglottis: The
upper part of the larynx above the vocal cords, including the
epiglottis.
- Glottis: The
middle part of the larynx where the vocal cords are located.
- Subglottis: The
lower part of the larynx between the vocal cords and the trachea (windpipe).
Use of tobacco products and drinking too much alcohol can affect the risk
of developing laryngeal cancer.
Possible signs of laryngeal cancer include a sore throat and
ear pain.
These and other symptoms may be caused by laryngeal cancer or by
other conditions. A doctor should be consulted if any of the following problems
occur:
- A sore throat or cough that does not go away.
- Trouble or pain when swallowing.
- Ear pain.
- A lump in the neck or throat.
- A change or hoarseness in the voice.
Tests that examine the throat and neck are used to help detect
(find), diagnose, and stage laryngeal cancer.
The following tests and procedures may be used:
- Physical exam of the throat and neck: An examination in which
the doctor feels for swollen lymph
nodes in the neck and looks down the throat with a small,
long-handled mirror to check for abnormal areas.
- Laryngoscopy: A
procedure in which the doctor examines the larynx (voice box) with a mirror or
with a laryngoscope (a thin, lighted
tube).
- Endoscopy: A
procedure to look at organs and tissues inside the body to check for abnormal areas. An endoscope (a thin, lighted tube) is inserted through an incision (cut) in the skin or opening in the body, such as the mouth. Tissue samples and lymph nodes may be taken for biopsy.
- CT scan (CAT
scan): A procedure that makes a series of detailed pictures of areas inside the body, taken from different angles. The pictures are made by a computer linked to an x-ray machine. A dye may be injected into a vein or swallowed to help the organs or tissues show up more clearly. This procedure is also called computed tomography, computerized tomography, or computerized axial tomography.
- MRI (magnetic resonance imaging): A procedure that uses a magnet, radio waves, and a computer to make a series of detailed pictures of areas inside the body. This procedure is also called nuclear magnetic resonance imaging (NMRI).
- Biopsy: The removal of cells or tissues so they can be viewed under a microscope to check for signs of cancer.
- Barium swallow: A series of x-rays of the esophagus and stomach. The patient drinks a liquid that contains barium (a silver-white metallic compound). The liquid coats the esophagus and stomach, and x-rays are taken. This procedure is also called an upper GI series.
Certain factors affect prognosis (chance
of recovery) and treatment options.
Prognosis (chance of recovery) depends on the following:
- The stage of the disease.
- The location and size of the tumor.
- The grade of the tumor.
- The patient's age, gender, and general health, including whether the patient is anemic.
Treatment options depend on the following:
- The stage of the disease.
- The location and size of the tumor.
- Keeping the patient's ability to talk, eat, and breathe as normal as possible.
- Whether the cancer has come back (recurred).
Smoking tobacco and drinking alcohol decrease the effectiveness of
treatment for laryngeal cancer. Patients with laryngeal cancer who continue to smoke and drink are less likely to be cured and more likely to develop a second tumor. After treatment for laryngeal cancer,
frequent and careful follow-up is important.

Stages of Laryngeal Cancer
After laryngeal cancer has been diagnosed, tests are done to
find out if cancer cells have spread within the larynx or to other parts of the
body.
The process used to find out if cancer has spread within the
larynx or to other parts of the body
is called staging. The information
gathered from the staging process determines the stage of the disease. It is important to know the
stage of the disease in order to plan treatment. The results of some of the tests used to diagnoselaryngeal cancer are often also used to stage the disease.
There are three ways that cancer spreads in the body.
The three ways that cancer spreads in the body are:
- Through tissue. Cancer invades the surrounding normal tissue.
- Through the lymph system. Cancer invades the lymph system and travels through the lymph vessels to other places in the body.
- Through the blood. Cancer invades the veins and capillaries and travels through the blood to other places in the body.
When cancer cells break away from the primary (original) tumor and travel through the lymph or blood to other places in the body, another (secondary) tumor may form. This process is called metastasis. The secondary (metastatic) tumor is the same type of cancer as the primary tumor. For example, if breast cancer spreads to the bones, the cancer cells in the bones are actually breast cancer cells. The disease is metastatic breast cancer, not bone cancer.
The following stages are used for laryngeal cancer:
Stage 0 (Carcinoma in Situ)
In stage 0, abnormalcells are found in the lining of the larynx.
These abnormal cells may become cancer and spread into nearby normal tissue. Stage 0 is also called carcinoma in
situ.
Stage I
In stage I, cancer has formed. Stage I laryngeal cancer depends on where cancer is
found in the larynx:
- Supraglottis:
Cancer is in one area of the supraglottis only and the
vocal cords can move
normally.
- Glottis: Cancer
is in one or both vocal cords and the vocal cords can move normally.
- Subglottis:
Cancer is in the subglottis only.
Stage II
In stage II, cancer is
in the larynx only. Stage II laryngeal cancer depends on where cancer is found
in the larynx:
- Supraglottis: Cancer is in more than one area of the
supraglottis or surrounding tissues.
- Glottis: Cancer has spread to the supraglottis and/or the
subglottis and/or the vocal cords do not move normally.
- Subglottis: Cancer has spread to one or both vocal cords, which may
not move normally.

Stage III
Stage III laryngeal cancer depends on whether cancer has spread from the supraglottis, glottis, or subglottis.
In stage III cancer of the supraglottis:
- cancer is in the larynx only and the vocal cords do not move
normally, and/or cancer is in tissues next to the larynx; cancer may have spread to one lymph node on the same side of
the neck as the original tumor and the lymph node is smaller than 3
centimeters; or
- cancer is in one area of the supraglottis only and in one lymph node on the same side of
the neck as the original tumor; the lymph node is smaller than 3
centimeters and the
vocal cords can move
normally; or
- cancer is in more than one area of the supraglottis or surrounding tissues and in one lymph node on the same side of
the neck as the original tumor; the lymph node is smaller than 3
centimeters and/or the vocal cords do not move normally.
In stage III cancer of the glottis:
- cancer is in the larynx only and the vocal cords do not move
normally, and/or cancer is in tissues next to the larynx; cancer may have spread to one lymph node on the same side of
the neck as the original tumor and the lymph node is smaller than 3
centimeters; or
- cancer
is in one or both vocal cords and in one lymph node on the same side of
the neck as the original tumor; the lymph node is smaller than 3
centimeters and the vocal cords can move normally; or
- cancer has spread to the supraglottis and/or the
subglottis and/or the vocal cords do not move normally. The cancer has also spread to one lymph node on the same side of
the neck as the original tumor and the lymph node is smaller than 3
centimeters.
In stage III cancer of the subglottis:
- cancer is in the larynx only and the vocal cords do not move
normally; cancer may have spread to one lymph node on the same side of
the neck as the original tumor and the lymph node is smaller than 3
centimeters; or
- cancer is in the subglottis only and in one lymph node on the same side of
the neck as the original tumor; the lymph node is smaller than 3
centimeters; or
- cancer has spread to one or both vocal cords, which may
not move normally, and to one lymph node on the same side of
the neck as the original tumor; the lymph node is smaller than 3
centimeters.
Stage IV
Stage IV is divided
into stage IVA, stage IVB, and stage IVC. Each substage is the same for cancer in the supraglottis, glottis, or subglottis.
- In stage IVA:
- cancer has spread through the thyroidcartilage and/or has spread to tissues beyond the larynx such as the neck, trachea, thyroid, or esophagus, and may have spread to one lymph node on the same side of
the neck as the original tumor; the lymph node is smaller than 3
centimeters; or
- cancer has spread to one or more lymph nodes anywhere in
the neck and the lymph nodes are smaller than 6 centimeters; cancer may have spread to tissues beyond the larynx, such as the neck, trachea, thyroid, or esophagus. Vocal cords may not move normally.
- In stage IVB:
- cancer has spread to the space in front of the spinal column and surrounds the carotid artery, or has spread to parts of the chest and may have spread to one or more lymph nodes anywhere in the neck (the lymph nodes may be any size); or
- cancer has spread to a lymph node that is larger than 6 centimeters and may have spread as far as the space in front of the spinal column, around the carotid artery or to parts of the chest. Vocal cords may not move normally.
- In stage IVC, cancer has spread beyond the larynx to other
parts of the body.

Recurrent Laryngeal Cancer
Recurrentlaryngeal cancer is cancer that has recurred (come back) after
it has been treated. The cancer is most likely to come back in the first 2 to 3 years. It may come back in the
larynx or in other parts of the
body.
Top
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.
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.
Surgery
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.
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.
Chemotherapy
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. When chemotherapy is taken by mouth or injected into a vein or muscle, the drugs enter the bloodstream and can reach cancer cells throughout the body (systemic chemotherapy). When chemotherapy is placed directly into the spinal column, an organ, or a body cavity such as the abdomen, the drugs mainly affect cancer cells in those areas (regional chemotherapy). The way the chemotherapy is given depends on the type and stage of the cancer being treated.
New types of treatment are being tested in clinical
trials.
This summary section describes treatments that are being studied in clinical trials. It may not mention every new treatment being studied. Information about clinical trials is available from the NCI Web site.
Chemoprevention
Chemoprevention is the use of drugs, vitamins, or other substances to reduce the risk of developing cancer or to reduce the risk cancer will recur (come back). The drug isotretinoin is being studied to prevent the development of a second cancer in patients who have had cancer of the head or neck.
Radiosensitizers
Radiosensitizers are drugs that make tumor cells more sensitive to radiation therapy. Combining radiation therapy with radiosensitizers may kill more tumor cells.
Patients may want to think about taking part in a clinical trial.
For some patients, taking part in a clinical trial may be the best treatment choice. Clinical trials are part of the cancer research process. Clinical trials are done to find out if new cancer treatments are safe and effective or better than the standard treatment.
Many of today's standard treatments for cancer are based on earlier clinical trials. Patients who take part in a clinical trial may receive the standard treatment or be among the first to receive a new treatment.
Patients who take part in clinical trials also help improve the way cancer will be treated in the future. Even when clinical trials do not lead to effective new treatments, they often answer important questions and help move research forward.
Patients can enter clinical trials before, during, or after starting their cancer treatment.
Some clinical trials only include patients who have not yet received treatment. Other trials test treatments for patients whose cancer has not gotten better. There are also clinical trials that test new ways to stop cancer from recurring (coming back) or reduce the side effects of cancer treatment.
Clinical trials are taking place in many parts of the country. See the Treatment Options section that follows for links to current treatment clinical trials. These have been retrieved from NCI's clinical trials database.
Follow-up tests may be needed.
Some of the tests that were done to diagnose the cancer or to find out the stage of the cancer may be repeated. Some tests will be repeated in order to see how well the treatment is working. Decisions about whether to continue, change, or stop treatment may be based on the results of these tests. This is sometimes called re-staging.
Some of the tests will continue to be done from time to time after treatment has ended. The results of these tests can show if your condition has changed or if the cancer has recurred (come back). These tests are sometimes called follow-up tests or check-ups.

General Information
Note: Estimated new cases and deaths from laryngeal cancer in the United States in 2009:[1]
- New cases: 12,290.
- Deaths: 3,660.
The larynx is divided into three anatomical regions. The supraglottic larynx
includes the epiglottis, false vocal cords, ventricles, aryepiglottic folds,
and arytenoids. The glottis includes the true vocal cords and the anterior and
posterior commissures. The subglottic region begins about 1 cm below
the true vocal cords and extends to the lower border of the cricoid cartilage
or the first tracheal ring.
The supraglottic area is rich in lymphatic drainage. After penetrating the
pre-epiglottic space and thyrohyoid membrane, lymphatic drainage is initially
to the jugulodigastric and midjugular nodes. About 25% to 50% of patients
present with involved lymph nodes. The precise figure depends on the T stage. The
true vocal cords are devoid of lymphatics. As a result, vocal cord cancer
confined to the true cords rarely, if ever, presents with involved lymph nodes.
Extension above or below the cords may, however, lead to lymph node
involvement. Primary subglottic cancers, which are quite rare, drain through
the cricothyroid and cricotracheal membranes to the pretracheal, paratracheal,
and inferior jugular nodes, and occasionally to mediastinal nodes.[2]
A clear association has been made between smoking, excess alcohol ingestion,
and the development of squamous cell cancers of the upper aerodigestive
tract.[3] For smokers, the risk of the development of laryngeal cancer decreases after the cessation of smoking but remains elevated even years later when compared to that of nonsmokers.[4] If a patient who has had a single cancer continues to smoke and drink
alcoholic beverages, the likelihood of a cure for the initial cancer, by any
modality, is diminished, and the risk of second tumor is enhanced. (Refer to the PDQ summary on Smoking Cessation and Continued Risk in Cancer Patients for more information.) Second
primary tumors, often in the aerodigestive tract, have been reported in as many as
25% of patients whose initial lesion is controlled. A study has shown that
daily treatment of these patients with moderate doses of isotretinoin
(i.e., 13-cis-retinoic acid) for 1 year can significantly reduce the incidence of
second tumors.[5] No survival advantage has yet been demonstrated, however, in
part because of recurrence and death from the primary malignancy.
Supraglottic cancers typically present with sore throat, painful swallowing,
referred ear pain, change in voice quality, or enlarged neck nodes. Early
vocal cord cancers are usually detected because of hoarseness. By the time
they are detected, cancers arising in the subglottic area commonly involve the
vocal cords; thus, symptoms usually relate to contiguous spread.
The most important adverse prognostic factors for laryngeal cancers include
increasing T stage and N stage. Other prognostic factors may include sex, age,
performance status, and a variety of pathologic features of the tumor,
including grade and depth of invasion.[6]
Prognosis for small laryngeal cancers that have not spread to lymph nodes is
very good, with cure rates of 75% to 95% depending on the site, tumor bulk,[7]
and degree of infiltration. Although most early lesions can be cured by either
radiation therapy or surgery, radiation therapy may be reasonable to preserve
the voice, leaving surgery for salvage. Patients with a preradiation
hemoglobin level higher than 13 g/dL have higher local control
and survival rates than patients who are anemic.[8] This observation is being
evaluated in a randomized clinical trial.
Locally advanced lesions, especially those with large clinically involved lymph
nodes, are poorly controlled with surgery, radiation therapy, or combined
modality treatment. Distant metastases are also common, even if the primary
tumor is controlled.
Intermediate lesions have intermediate prognoses, depending on site, T stage,
N stage, and performance status. Therapy recommendations for patients with
these lesions are based on a variety of complex anatomic, clinical, and social
factors, which should be individualized and discussed in multidisciplinary
consultation (surgery, radiation therapy, and dental and oral surgery) prior to
prescribing therapy.
Patients treated for laryngeal cancers are at the highest risk of recurrence in the
first 2 to 3 years. Recurrences after 5 years are rare and usually represent
new primary malignancies. Close, regular follow-up is crucial to maximize the
chance for salvage. Careful clinical examination and repetition of any
abnormal staging study are included in follow-up, along with attention to any
treatment-related toxic effect or complication.

Cellular Classification
The vast majority of laryngeal cancers are of squamous cell histology.
Squamous cell subtypes include keratinizing and nonkeratinizing and well-differentiated to poorly differentiated grade. A variety of nonsquamous cell
laryngeal cancers also occur.[1] These are not staged using the American Joint
Cancer Committee staging system, and their management, which is not discussed here, can
differ from that of squamous cell laryngeal cancers. In situ squamous cell
carcinoma of the larynx is usually managed by a conservative surgical procedure
such as mucosal stripping or superficial laser excision. Radiation therapy may
also be appropriate treatment of selected patients with in situ carcinoma of
the glottic larynx.[2]

Stage Information
The staging system is clinical and based on the best possible estimate of the
extent of disease before treatment. The assessment of the primary tumor is
based on inspection and palpation when possible and by both indirect mirror
examination and direct endoscopy when necessary. The tumor must be confirmed
histologically, and any other pathological data obtained on biopsy may be
included. Head and neck magnetic resonance imaging or computed tomography
should be done prior to therapy to supplement inspection and palpation.[1]
Additional radiographic studies may be included. The appropriate nodal
drainage areas in the neck are examined by careful palpation.
The American Joint Committee on Cancer (AJCC) has designated staging by TNM
classification.[2]
TNM Definitions
Primary tumor (T)
- TX: Primary tumor cannot be assessed
- T0: No evidence of primary tumor
- Tis: Carcinoma in situ
Supraglottis
Supraglottis involves many individual subsites. Relapse-free survival may
differ by subsite and by T and N groupings within stage.
Glottis
- T1: Tumor limited to the vocal cord(s), which may involve anterior or posterior
commissure, with normal mobility
- T1a: Tumor limited to one vocal cord
- T1b: Tumor involves both vocal cords
- T2: Tumor extends to supraglottis and/or subglottis and/or with impaired
vocal cord mobility
- T3: Tumor limited to the larynx with vocal cord fixation and/or invades paraglottic space, and/or minor thyroid cartilage erosion (e.g., inner cortex)
- T4a: Tumor invades through the thyroid cartilage and/or invades tissues
beyond the larynx (e.g., trachea, soft tissues of neck, including
deep extrinsic muscle of the tongue, strap muscles, thyroid, or esophagus)
- T4b: Tumor invades prevertebral space, encases carotid artery, or invades mediastinal structures
Glottic presentation may vary by volume of tumor, anatomic region involved, and
the presence or absence of normal cord mobility. Relapse-free survival may
differ by these and other factors in addition to T and N subgroupings within
the stage.
Subglottis
- T1: Tumor limited to the subglottis
- T2: Tumor extends to vocal cord(s) with normal or impaired mobility
- T3: Tumor limited to larynx with vocal cord fixation
- T4a: Tumor invades cricoid or thyroid cartilage and/or invades tissues beyond the larynx (e.g., trachea, soft tissues of neck,
including deep extrinsic muscles of the tongue, strap muscles, thyroid, or esophagus)
- T4b: Tumor invades prevertebral space, encases carotid artery, or invades mediastinal structures
Regional lymph nodes (N)
- NX: Regional lymph nodes cannot be assessed
- N0: No regional lymph node metastasis
- N1: Metastasis in a single ipsilateral lymph node 3 cm or smaller in greatest
dimension
- N2: Metastasis in a single ipsilateral lymph node larger than 3 cm but 6 cm or smaller in greatest dimension, or in multiple ipsilateral lymph
nodes 6 cm or smaller in greatest dimension, or in bilateral or
contralateral lymph nodes 6 cm or smaller in greatest dimension
- N2a: Metastasis in a single ipsilateral lymph node larger than 3 cm
but 6 cm or smaller in greatest dimension
- N2b: Metastasis in multiple ipsilateral lymph nodes 6 cm or smaller in greatest dimension
- N2c: Metastasis in bilateral or contralateral lymph nodes 6 cm or smaller in greatest dimension
- N3: Metastasis in a lymph node larger than 6 cm in greatest dimension
In clinical evaluation, the actual size of the nodal mass should be measured,
and allowance should be made for intervening soft tissues. Most masses larger than 3 cm in diameter are not single nodes but confluent nodes or
tumors in soft tissues of the neck. There are three stages of clinically positive
nodes: N1, N2, and N3. The use of subgroups a, b, and c is not required but
recommended. Midline nodes are considered homolateral nodes.
Distant metastasis (M)
- MX: Distant metastasis cannot be assessed
- M0: No distant metastasis
- M1: Distant metastasis

Evaluation of treatment outcome can be reported in various ways: locoregional
control, disease-free survival, determinate survival, and overall survival at 2
to 5 years. Preservation of voice is an important parameter to evaluate.
Outcome should be reported after initial surgery, initial radiation, planned
combined treatment, or surgical salvage of radiation failures. Primary source
material should be consulted to review these differences.
Because of clinical problems related to smoking and alcohol use in this
population, many patients succumb to intercurrent illness rather than to the
primary cancer.
Direct comparison of results of radiation versus surgery is complicated.
Surgical studies can report outcome based on pathologic staging, whereas
radiation studies must report on clinical staging, with the obvious problem of
understaging in patients treated with radiation, particularly in the neck. In
addition, radiation alone is often recommended for patients with poor
performance status, which leads to less favorable results.

Treatment Option Overview
Note: Some citations in the text of this section are followed by a level of

reader judge the strength of evidence linked to the reported results of a
therapeutic strategy. (Refer to the PDQ summary on Levels of Evidence for more
information.)
Small superficial cancers without laryngeal fixation or lymph node involvement
are successfully treated by radiation therapy or surgery alone, including laser
excision surgery. Radiation therapy may be selected to preserve the voice
and to reserve surgery for salvaging failures. The radiation field and dose are
determined by the location and size of the primary tumor. A variety of
curative surgical procedures are also recommended for laryngeal cancers, some
of which preserve vocal function. An appropriate surgical procedure must be
considered for each patient, given the anatomic problem, performance status,
and clinical expertise of the treatment team. Advanced laryngeal cancers are
often treated by combining radiation and surgery.[1][2][3][4] A review of published clinical
results of radical radiation therapy for head and neck cancer suggests a
significant loss of local control when the administration of radiation therapy
was prolonged; therefore, lengthening of standard treatment schedules should be
avoided whenever possible.[5][6] Because the cure rate
for advanced lesions is low, clinical trials exploring chemotherapy,
hyperfractionated radiation therapy,[7] radiation sensitizers, or particle-beam
radiation therapy should be considered.[8][9] Although cure rates are not changed with chemoradiation administered in a neoadjuvant setting, organ preservation is increased.[10]
A multi-institutional trial randomized patients to induction cisplatin plus fluorouracil (5-FU) followed by radiation therapy, radiation therapy administered concurrently with cisplatin, or radiation therapy alone.[10] Concurrent radiation therapy plus cisplatin resulted in a statistically significantly higher percentage of patients with an intact larynx at 2 years (i.e., 88% vs. 75% and 70% for concurrent chemotherapy, induction chemotherapy, and radiation alone, respectively) and higher locoregional control (i.e., 78% vs. 61% and 56%, respectively) than the other two regimens. Both chemotherapy regimens had a lower incidence of distant metastases and better relapse-free survivals than radiation therapy alone, but they also had a higher rate of high-grade toxic effects. Overall survival rates were not significantly different between the different groups.[10][Level of evidence: 1iiC]
The risk of lymph node metastases in patients with stage I glottic cancer
ranges from 0% to 2%, and for more advanced disease, such as stage II and stage
III glottic, the incidence is only 10% and 15%, respectively. Thus, there is
no need to treat glottic cancer cervical lymph nodes electively in patients
with stage I tumors and small stage II tumors. Consideration should be given
to using elective neck radiation for larger or supraglottic tumors.[11]
For patients with cancer of the subglottis, combined modality therapy is
generally preferred though for the uncommon small lesions (i.e., stage I or stage
II), radiation therapy alone may be used.
Patients who smoke during radiation therapy appear to have lower response rates
and shorter survival durations than those who do not;[12] therefore, patients
should be counseled to stop smoking before beginning radiation therapy.
Accumulating evidence has demonstrated a high incidence (i.e., >30%–40%) of
hypothyroidism in patients who have received external-beam radiation to the
entire thyroid gland or to the pituitary gland. Thyroid-junction testing of
patients should be considered prior to therapy and as part of posttreatment
follow-up.[13][14]

Stage I Laryngeal Cancer
Supraglottis
Standard treatment options:
- External-beam radiation therapy alone.
- Supraglottic laryngectomy. Total laryngectomy may be reserved for patients
unable to tolerate potential respiratory complications of surgery or the
supraglottic laryngectomy. Radiation, however, should be preferred because of
the good results, preservation of the voice, and the possibility of surgical salvage in
patients whose disease recurs locally.[1]
Glottis
Standard treatment options:
- Radiation therapy.[2][3][4][5]
- Cordectomy for very carefully selected patients with limited and superficial
T1 lesions.[6][7]
- Partial or hemilaryngectomy or total laryngectomy, depending on anatomic
considerations.
- Laser excision.[6]
Subglottis
Standard treatment options:
- Lesions can be treated successfully by radiation therapy alone with
preservation of normal voice. Surgery is reserved for failure of radiation
therapy or for patients who cannot be easily assessed for radiation therapy.
Current Clinical Trials
Check for U.S. clinical trials from NCI's PDQ Cancer Clinical Trials Registry that are now accepting patients with
stage I laryngeal cancer. The list of clinical trials can be further narrowed by location, drug, intervention, and other criteria.

the lesion, clinical status of the patient, and expertise of the treatment
team. Careful selection must be made to ensure adequate pulmonary and
swallowing function postoperatively. Radiation should be preferred because
of the good results, preservation of the voice, and the possibility of surgical salvage in
patients whose disease recurs locally.[3]
- Postoperative radiation therapy is indicated for positive or close
surgical margins.
Treatment options under clinical evaluation:
- Hyperfractionated radiation therapy to improve tumor control rates and
diminish late toxicity to normal tissue.[2][4]
- Isotretinoin (i.e., 13-cis-retinoic acid) daily for 1 year to prevent development
of second upper aerodigestive tract primary tumors.[5]
Glottis

- Radiation therapy.[1][2][6][7][8]
- Partial or hemilaryngectomy or total laryngectomy, depending on anatomic
considerations. Under certain circumstances, laser microsurgery may be
appropriate.[9]

Subglottis
Standard treatment options:
- Lesions can be treated successfully by radiation therapy alone with
preservation of normal voice.[1][2] Surgery is reserved for failure of
radiation therapy or for patients in whom follow-up is likely to be difficult.

Stage III Laryngeal Cancer
Supraglottis
Standard treatment options:
- Surgery with or without postoperative radiation therapy, as evidenced in RTOG-7303, for example.[1][2][3][4][5][6]
- Definitive radiation therapy with surgery for salvage of radiation
failures.[7]
- Chemotherapy administered concomitantly with radiation therapy can
be considered for patients who would require total laryngectomy for control of disease. Laryngectomy would be reserved for patients with less than a 50%
response to chemotherapy or who have persistent disease following
radiation.[8][9][10][11][12][13]
Treatment options under clinical evaluation:
- Hyperfractionated radiation therapy to improve tumor control rates and
diminish late toxicity to normal tissue.[14][15]
- Clinical trials exploring chemotherapy, radiosensitizers, or particle-beam
radiation therapy.[16][17][18][19][20]
A meta-analysis of three trials of patients with locally advanced laryngeal
carcinomas compared patients who received standard radical surgery plus
radiation therapy with patients who received neoadjuvant cisplatin and
fluorouracil (5-FU), followed by radiation therapy alone in responders or radical
surgery plus radiation therapy in nonresponders.[21] The meta-analysis
demonstrated a nonsignificant trend in favor of the control group who received
standard radical surgery plus radiation therapy with an absolute negative
effect in the chemotherapy arm that reduced survival at 5 years by 6%. The
possibility of a slightly decreased survival must be balanced by the retention
of the larynx in those patients whose disease was controlled.

Standard treatment options:
- Laryngectomy plus isolated thyroidectomy and tracheoesophageal node
dissection usually followed by postoperative radiation therapy.[1][2][3]
- Treatment by radiation therapy alone is indicated for patients who are not
candidates for surgery. Patients should be closely followed, and surgical
salvage should be planned for recurrences that are local or in the neck.

Recurrent Laryngeal Cancer
Treatment of recurrent supraglottic, glottic, and subglottic cancer includes
further surgery or clinical trials.[1][2][3][4]
Standard treatment options:
Treatment options under clinical evaluation:
- Patients whose disease does not respond to combined radiation therapy and
surgery probably are best treated by palliative chemotherapy in clinical
trials.
Current Clinical Trials
Check for U.S. clinical trials from NCI's PDQ Cancer Clinical Trials Registry that are now accepting patients with
recurrent laryngeal cancer. The list of clinical trials can be further narrowed by location, drug, intervention, and other criteria.
