Paranasal sinus and nasal cavity cancer is a disease in which
malignant (cancer) cells form in the tissues of the paranasal sinuses and nasal
cavity.
Paranasal sinuses
"Paranasal" means near the nose. The paranasal sinuses are hollow, air-filled spaces in the bones around the nose. The sinuses are lined with cells that make mucus, which keeps the inside of the nose from drying out during breathing.
There are several paranasal sinuses named after the bones that surround them:
- The frontal sinuses are in the lower forehead above the nose.
- The maxillary sinuses are in the cheekbones on either side of the nose.
- The ethmoid sinuses are beside the upper nose, between the eyes.
- The sphenoid sinuses are behind the nose, in the center of the skull.
Nasal cavity
The nose opens into the nasal cavity, which is divided into two nasal passages. Air moves through these passages during breathing. The nasal cavity lies above the bone that forms the roof of the mouth and curves down at the back to join the throat. The area just inside the nostrils is called the nasal vestibule. A small area of special cells in the roof of each nasal passage sends signals to the brain to give the sense of smell.
Together the paranasal sinuses and the nasal cavity filter and warm the air, and make it moist before it goes into the lungs. The movement of air through the sinuses and other parts of the respiratory system help make sounds for talking.
Different
types of cells in the paranasal sinus and nasal cavity may become malignant.
The most common type of paranasal sinus and nasal cavity cancer is squamous cell carcinoma. This type of cancer forms in the squamous cells (thin, flat cells) lining the inside of the paranasal sinuses and the nasal cavity.
Other types of paranasal sinus and nasal cavity cancer include the following:
Being exposed to certain chemicals or dust in the workplace can increase the risk of developing paranasal sinus and nasal cavity cancer.
Anything that increases your chance of getting a disease is called a risk factor. Having a risk factor does not mean that you will get cancer; not having risk factors doesn’t mean that you will not get cancer. People who think they may be at risk should discuss this with their doctor. Risk factors for paranasal sinus and nasal cavity cancer include the following:
- Being exposed to certain workplace chemicals or dust, such as those found in the following jobs:
- Furniture-making.
- Sawmill work.
- Woodworking (carpentry).
- Shoemaking.
- Metal-plating.
- Flour mill or bakery work.
- Being male and older than 40 years.
- Smoking.
Possible signs of paranasal sinus and nasal cavity cancer
include sinus problems and nosebleeds.
These and other symptoms may be caused by paranasal sinus and
nasal cavity cancer. Other conditions may cause the same symptoms. There may be no symptoms in the early stages. Symptoms may appear as the tumor grows. A doctor should be consulted if any
of the following problems occur:
- Blocked sinuses that do not clear, or sinus pressure.
- Headaches or pain in the sinus areas.
- A runny nose.
- Nosebleeds.
- A lump or sore inside the nose that does not heal.
- A lump on the face or roof of the mouth.
- Numbness or tingling in the face.
- Swelling or other trouble with the eyes, such as double vision or the eyes pointing in different directions.
- Pain in the upper teeth, loose teeth, or dentures that no longer fit well.
- Pain or pressure in the ear.
Tests that examine the sinuses and nasal cavity are used to detect
(find) and diagnose paranasal sinus and nasal cavity cancer.
The following tests and procedures may be used:
- Physical exam and history: An exam of the body to check general signs of health, including checking for signs of disease, such as lumps or anything else that seems unusual. A history of the patient’s health habits and past illnesses and treatments will also be taken.
- Physical exam of the nose, face, and neck: An exam in
which the doctor looks into the nose with a small, long-handled mirror to check
for abnormal areas and checks the face and neck for lumps or swollen lymph
nodes.
- X-rays of the head, neck, and chest: An x-ray is a type of energy beam that can go through the body and onto film, making a picture of areas inside the body.
- Nasoscopy: A procedure to look inside the nose for abnormal areas. A nasoscope is inserted into the nose. A nasoscope is a thin, tube-like instrument with a light and a lens for viewing. It may also have a tool to remove tissue samples, which are checked under a microscope for signs of cancer.
- Biopsy: The removal of cells or tissues so they can be viewed under a microscope by a pathologist to check for signs of cancer.
Certain factors affect prognosis (chance of recovery) and treatment options.
The prognosis (chance of recovery) and treatment options depend on the following:
- Where the tumor is in the paranasal sinus or nasal cavity and whether it has spread.
- The size of the tumor.
- The type of cancer.
- The patient's age and general
health.
- Whether the cancer has just been diagnosed or has recurred (come back).
Paranasal sinus and nasal cavity cancers often have spread by the time they are diagnosed and are hard to cure. After treatment, a
lifetime of frequent and careful follow-up is important because there is an increased risk of
developing a second kind of cancer in the head or neck.
Stages of Paranasal Sinus and Nasal Cavity Cancer
Key Points for This Section
|
|
After paranasal sinus and nasal cavity cancer has been
diagnosed, tests are done to find out if cancer cells have spread within the
paranasal sinuses and nasal cavity or to other parts of the body.
The process used to find out if cancer has spread within the paranasal sinuses and nasal cavity 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 in order to plan treatment. The following tests
and procedures may be used in the staging process:
- X-rays of the head, neck, and chest: An x-ray is a type of energy beam that can go through the body and onto film, making a picture of areas inside the body.
- Endoscopy: A procedure to look at organs and tissues inside the body to check for abnormal areas. An endoscope is inserted through an opening in the body, such as the nose or mouth. An endoscope is a thin, tube-like instrument with a light and a lens for viewing. It may also have a tool to remove tissue or lymph node samples, which are checked under a microscope for signs of disease.
- 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) with gadolinium: A procedure that uses a magnet, radio waves, and a computer to make a series of detailed pictures of areas inside the body. Sometimes a substance called gadolinium is injected into a vein. The gadolinium collects around the cancer cells so they show up brighter in the picture. This procedure is also called nuclear magnetic resonance imaging (NMRI).
- Bone scan: A procedure to check if there are rapidly dividing cells, such as cancer cells, in the bone. A very small amount of radioactive material is injected into a vein and travels through the bloodstream. The radioactive material collects in the bones and is detected by a scanner.
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.
There is no standard staging system for cancer of the
sphenoid and frontal sinuses.

Recurrent Paranasal Sinus and Nasal Cavity Cancer
Recurrent paranasal sinus
and nasal cavity cancer is cancer that
has recurred (come back) after it has been treated. The cancer may come back in the paranasal sinuses and nasal cavity
or in other parts of the body. Treatment Option Overview
Key Points for This Section
|
|
There are different types of treatment for patients with
paranasal sinus and nasal cavity cancer.
Different types of treatment are available for patients with paranasal sinus and nasal cavity 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.
Patients with paranasal sinus and nasal
cavity cancer should have their treatment planned by a team of doctors with expertise in treating head and neck cancer.
Treatment will be overseen by a medical oncologist, a doctor who specializes in treating people with cancer. The medical oncologist works with other doctors who are experts in treating patients with head and neck cancer and who specialize in certain areas of medicine and rehabilitation. Patients who have paranasal sinus and nasal
cavity cancer may need special help
adjusting to breathing problems or other side effects of the cancer and its treatment. If a large amount of tissue or bone around the paranasal sinuses or nasal cavity is taken out, plastic surgery may be done to repair or rebuild the area. The treatment team may include the following specialists:
Three types of standard treatment are used:
Surgery
Surgery (removing the cancer in an operation) is a common
treatment for all stages of
paranasal sinus and nasal cavity cancer. A doctor may remove the cancer and
some of the healthy tissue and bone around the cancer. If the cancer
has spread, the doctor may remove lymph nodes and other tissues in the
neck.
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 surgery, to increase the chances of a cure, is called adjuvant therapy.
Radiation therapy
Radiation therapy is a cancer treatment that uses high-energy x-rays or other types of radiation to kill cancer cells or keep them from growing. There are two types of radiation therapy. External radiation therapy uses a machine outside the body to send radiation toward the cancer. The total dose of radiation therapy is sometimes divided into several smaller, equal doses delivered over a period of several days.
This is called fractionation. 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.
External radiation therapy to the thyroid or the pituitary gland may change the way the thyroid
gland works. The thyroid gland may be tested before and after
treatment.
Chemotherapy
Chemotherapy is a cancer treatment that uses drugs to stop the growth of cancer cells, either by killing the cells or by stopping them 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). Combination chemotherapy is treatment using more than one anticancer drug.
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.
Information about clinical trials is available from the
NCI Web site 1.
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.
Treatment Options by Stage
A link to a list of current clinical trials is included for each treatment section. For some types or stages of cancer, there may not be any trials listed. Check with your doctor for clinical trials that are not listed here but may be right for you.

About PDQ
PDQ is a comprehensive cancer database available on NCI's Web site.
PDQ is the National Cancer Institute's (NCI's) comprehensive cancer information database. Most of the information contained in PDQ is available online at NCI's Web site 21. PDQ is provided as a service of the NCI. The NCI is part of the National Institutes of Health, the federal government's focal point for biomedical research.
PDQ contains cancer information summaries.
The PDQ database contains summaries of the latest published information on cancer prevention, detection, genetics, treatment, supportive care, and complementary and alternative medicine. Most summaries are available in two versions. The health professional versions provide detailed information written in technical language. The patient versions are written in easy-to-understand, nontechnical language. Both versions provide current and accurate cancer information.
The PDQ cancer information summaries are developed by cancer experts and reviewed regularly.
Editorial Boards made up of experts in oncology and related specialties are responsible for writing and maintaining the cancer information summaries. The summaries are reviewed regularly and changes are made as new information becomes available. The date on each summary ("Date Last Modified") indicates the time of the most recent change.
PDQ also contains information on clinical trials.
A clinical trial is a study to answer a scientific question, such as whether one treatment is better than another. Trials are based on past studies and what has been learned in the laboratory. Each trial answers certain scientific questions in order to find new and better ways to help cancer patients. During treatment clinical trials, information is collected about the effects of a new treatment and how well it works. If a clinical trial shows that a new treatment is better than one currently being used, the new treatment may become "standard." 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.
Listings of clinical trials are included in PDQ and are available online at NCI's Web site 27. Descriptions of the trials are available in health professional and patient versions. Many cancer doctors who take part in clinical trials are also listed in PDQ. For more information, call the Cancer Information Service 1-800-4-CANCER (1-800-422-6237); TTY at 1-800-332-8615. |
