Carcinoma of Lip
Anything that increases your risk 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 lip and oral cavity cancer include the following:
Possible signs of lip and oral cavity cancer include a sore or lump on the lips or in the mouth. These and other symptoms may be caused by lip and oral cavity cancer. Other conditions may cause the same symptoms. A doctor should be consulted if any of the following problems occur:
Lip and oral cavity cancer may not have any symptoms and is sometimes found during a regular dental exam. Tests that examine the mouth and throat are used to detect (find), diagnose, and stage lip and oral cavity cancer. The following tests and procedures may be used:
Certain factors affect prognosis (chance of recovery) and treatment options. Prognosis (chance of recovery) depends on the following:
For patients who smoke, the chance of recovery is better if they stop smoking before beginning radiation therapy. Treatment options depend on the following:
Patients who have had lip and oral cavity cancer have an increased risk of developing a second cancer in the head or neck. Frequent and careful follow-up is important. Clinical trials are studying the use of retinoid drugs to reduce the risk of a second head and neck cancer
After lip and oral cavity cancer has been diagnosed, tests are done to find out if cancer cells have spread within the lip and oral cavity or to other parts of the body. The process used to find out if cancer has spread within the lip and oral 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 results of the tests used to diagnose lip and oral cavity cancer are also used to stage the disease. (See the General Information section.) There are three ways that cancer spreads in the body. The three ways that cancer spreads in the body are:
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 lip and oral cavity cancer:
Stage 0 (Carcinoma in Situ) In stage 0, abnormal cells are found in the lining of the lips and oral cavity. 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 and the tumor is 2 centimeters or smaller. Cancer has not spread to the lymph nodes. Stage II In stage II, the tumor is larger than 2 centimeters but not larger than 4 centimeters, and cancer has not spread to the lymph nodes. Stage III In stage III, the tumor:
Stage IV Stage IV is divided into stages IVA, IVB, and IVC.
Different types of treatment are available for patients with lip and oral 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 lip and oral cavity cancer should have their treatment planned by a team of doctors who are expert in treating head and neck cancer. Treatment will be overseen by a medical oncologist, a doctor who specializes in treating people with cancer. Because the lips and oral cavity are important for breathing, eating, and talking, patients may need special help adjusting to the side effects of the cancer and its treatment. The medical oncologist may refer the patient to other health professionals with special training in the treatment of patients with head and neck cancer. These include the following:
Two types of standard treatment are used: Surgery Surgery (removing the cancer in an operation) is a common treatment for all stages of lip and oral cavity cancer. Surgery may include the following:
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. 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. For patients who smoke, radiation therapy works better when smoking is stopped before beginning treatment. It is also important for patients to have a dental exam before radiation therapy begins, so that existing problems can be 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. 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 cerebrospinal fluid, 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. Hyperfractionated radiation therapy Hyperfractionated radiation therapy is radiation treatment in which the total dose of radiation is divided into small doses and the treatments are given more than once a day. Hyperthermia therapy Hyperthermia therapy is a treatment in which body tissue is heated above normal temperature to damage and kill cancer cells or to make cancer cells more sensitive to the effects of radiation and certain anticancer drugs. 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 listing of clinical trials. 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 for Recurrent Lip and Oral Cavity Cancer
Treatment of recurrent lip and oral cavity cancer may include the following:
Check for U.S. clinical trials from NCI's list of cancer clinical trials that are now accepting patients with recurrent lip and oral cavity cancer. For more specific results, refine the search by using other search features, such as the location of the trial, the type of treatment, or the name of the drug .
