Expert-reviewed information summary about the treatment of urethral cancer.
The urethra is the tube that carries urine from the bladder to outside the body. In women, the urethra is about 1½ inches long and is just above the vagina. In men, the urethra is about 8 inches long, and goes through the prostate gland and the penis to the outside of the body. In men, the urethra also carries semen.
Urethral cancer is a rare cancer that occurs more often in men than in women.
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 doesnât mean that you will not get cancer. Talk with your doctor if you think you may be at risk. Risk factors for urethral cancer include the following:
These and other symptoms may be caused by urethral cancer. Other conditions may cause the same symptoms. Sometimes early cancer of the urethra does not cause any symptoms at all. Check with your doctor if you have any of the following problems:
The following tests and procedures may be used:
The process used to find out if cancer has spread within the urethra 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 procedures may be used in the staging process:
The metastatic tumor is the same type of cancer as the primary tumor. For example, if urethral cancer spreads to the lung, the cancer cells in the lung are actually urethral cancer cells. The disease is metastatic urethral cancer, not lung cancer.
Urethral cancer is staged and treated based on the part of the urethra that is affected and how deeply the tumor has spread into tissue around the urethra. Urethral cancer can be described as distal or proximal.Anatomy of the distal and proximal urethra. Urine flows out of the bladder and leaves the body through the urethra. The part of the urethra that is closest to the bladder is called the proximal urethra. The part that is closest to where the urine leaves the body is called the distal urethra. The urethra is about 8 inches long in men and about 1½ inches long in women.
In distal urethral cancer, the cancer usually has not spread deeply into the tissue. In women, the part of the urethra that is closest to the outside of the body (about ½ inch) is affected. In men, the part of the urethra that is in the penis is affected.
In men, cancer that forms in the proximal urethra (the part of the urethra that passes through the prostate to the bladder) may occur at the same time as cancer of the bladder and/or prostate. Sometimes this occurs at diagnosis and sometimes it occurs later.
Recurrent urethral cancer is cancer that has recurred (come back) after it has been treated. The cancer may come back in the urethra or in other parts of the body.
Different types of treatments are available for patients with urethral 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.
If the urethra is removed, the surgeon will make a new way for the urine to pass from the body. This is called urinary diversion. If the bladder is removed, the surgeon will make a new way for urine to be stored and passed from the body. The surgeon may use part of the small intestine to make a tube that passes urine through an opening ( stoma). This is called an ostomy or urostomy. If a patient has an ostomy, a disposable bag to collect urine is worn under clothing. The surgeon may also use part of the small intestine to make a new storage pouch ( continent reservoir) inside the body where the urine can collect. A tube ( catheter) is then used to drain the urine through a stoma.
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 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 of cancer and where the cancer formed in the urethra.
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 of cancer and where the cancer formed in the urethra.
Active surveillance is following a patient's condition without giving any treatment unless there are changes in test results. It is used to find early signs that the condition is getting worse. In active surveillance, patients are given certain exams and tests, including biopsies, on a regular schedule.
Information about clinical trials is available from the NCI Web site.
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.
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.
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 of abnormal cells in the mucosa (inside lining of the urethra that have not become cancer, may include surgery to remove the tumor ( open excision or transurethral resection), electroresection with fulguration, or laser surgery.
Treatment of distal urethral cancer is different for men and women.
For women, treatment may include the following:
For men, treatment may include the following:
Check for U.S. clinical trials from NCI's list of cancer clinical trials that are now accepting patients with distal urethral 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. Talk with your doctor about clinical trials that may be right for you. General information about clinical trials is available from the NCI Web site.

The PDQ cancer information summaries are reviewed regularly and updated as new information becomes available. This section describes the latest changes made to this summary as of the date above.
Editorial changes were made to this summary.
Physician Data Query (PDQ) is the National Cancer Institute's (NCI's) comprehensive cancer information database. 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 come in two versions. The health professional versions have detailed information written in technical language. The patient versions are written in easy-to-understand, nontechnical language. Both versions have cancer information that is accurate and up to date and most versions are also available in Spanish.
PDQ is a service of the NCI. The NCI is part of the National Institutes of Health (NIH). NIH is the federal governmentâs center of biomedical research. The PDQ summaries are based on an independent review of the medical literature. They are not policy statements of the NCI or the NIH.
This PDQ cancer information summary has current information about the treatment of urethral cancer. It is meant to inform and help patients, families, and caregivers. It does not give formal guidelines or recommendations for making decisions about health care.
Editorial Boards write the PDQ cancer information summaries and keep them up to date. These Boards are made up of experts in cancer treatment and other specialties related to cancer. The summaries are reviewed regularly and changes are made when there is new information. The date on each summary ("Date Last Modified") is the date of the most recent change.
The information in this patient summary was taken from the health professional version, which is reviewed regularly and updated as needed, by the PDQ Adult Treatment Editorial Board.
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.
Clinical trials are listed in PDQ and can be found online at NCI's Web site. 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).
