General Information About Urethral Cancer

KEY POINTS

• Urethral cancer is a disease in which malignant (cancer) cells form in the tissues of the urethra.
• There are different types of urethral cancer that begin in cells that line the urethra.
• A history of bladder cancer can affect the risk of urethral cancer.
• Signs of urethral cancer include bleeding or trouble with urination.
• Tests that examine the urethra and bladder are used to detect (find) and diagnose urethral cancer.
• Certain factors affect prognosis (chance of recovery) and treatment options.

Urethral cancer is a disease in which malignant (cancer) cells form in the tissues of the urethra.

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.

Urine is made in the renal tubules and collects in the renal pelvis of each kidney. The urine flows from the kidneys through the ureters to the bladder. The urine is stored in the bladder until it leaves the body through the urethra.

Urethral cancer is a rare cancer that occurs more often in men than in women.

There are different types of urethral cancer that begin in cells that line the urethra.

These cancers are named for the types of cells that become malignant (cancer):

• Squamous cell carcinoma is the most common type of urethral cancer. It forms in cells in the part of the urethra near the bladder in women, and in the lining of the urethra in the penis in men.
• Transitional cell carcinoma forms in the area near the urethral opening in women, and in the part of the urethra that goes through the prostate gland in men.
• Adenocarcinoma forms in the glands that are around the urethra in both men and women.

Urethral cancer can metastasize (spread) quickly to tissues around the urethra and is often found in nearby lymph nodes by the time it is diagnosed.

A history of bladder cancer can affect the risk of urethral 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. Talk with your doctor if you think you may be at risk. Risk factors for urethral cancer include the following:

• Having a history of bladder cancer.
• Having conditions that cause chronic inflammation in the urethra, including:
  • Sexually transmitted diseases (STDs), including human papillomavirus (HPV), especially HPV type 16.
  • Frequent urinary tract infections (UTIs).

Signs of urethral cancer include bleeding or trouble with urination.

These and other signs and symptoms may be caused by urethral cancer or by other conditions. There may be no signs or symptoms in the early stages. Check with your doctor if you have any of the following:

• Trouble starting the flow of urine.
• Weak or interrupted ("stop-and-go") flow of urine.
• Frequent urination, especially at night.
• Incontinence.
• Discharge from the urethra.
• Bleeding from the urethra or blood in the urine.
• A lump or thickness in the perineum or penis.
• A painless lump or swelling in the groin.

Tests that examine the urethra and bladder are used to detect (find) and diagnose urethral 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.
• Pelvic exam : An exam of the vagina, cervix, uterus, fallopian tubes, ovaries, and rectum. A speculum is inserted into the vagina and the doctor or nurse looks at the vagina and cervix for signs of disease. The doctor or nurse also inserts one or two lubricated, gloved fingers of one hand into the vagina and places the other hand over the lower abdomen to feel the size, shape, and position of the uterus and ovaries. The doctor or nurse also inserts a lubricated, gloved finger into the rectum to feel for lumps or abnormal areas.

  Pelvic exam. A doctor or nurse inserts one or two lubricated, gloved fingers of one hand into the vagina and presses on the lower abdomen with the other hand. This is done to feel the size, shape, and position of the uterus and ovaries. The vagina, cervix, fallopian tubes, and rectum are also checked.

• Digital rectal exam : An exam of the rectum. The doctor or nurse inserts a lubricated, gloved finger into the lower part of the rectum to feel for lumps or anything else that seems unusual.
• Urine cytology : A laboratory test in which a sample of urine is checked under a microscope for abnormal cells.
• Urinalysis : A test to check the color of urine and its contents, such as sugar, protein, blood, and white blood cells. If white blood cells (a sign of infection) are found, a urine culture is usually done to find out what type of infection it is.
• Blood chemistry studies : A procedure in which a blood sample is checked to measure the amounts of certain substances released into the blood by organs and tissues in the body. An unusual (higher or lower than normal) amount of a substance can be a sign of disease.
• Complete blood count (CBC): A procedure in which a sample of blood is drawn and checked for the following:
  • The number of red blood cells, white blood cells, and platelets.
  • The amount of hemoglobin (the protein that carries oxygen) in the red blood cells.
  • The portion of the blood sample made up of red blood cells.
• CT scan (CAT scan): A procedure that makes a series of detailed pictures of areas inside the body, such as the pelvis and abdomen, taken from different angles. The pictures are made by a computer linked to an x-ray machine. A dye may be injectedinto 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.
• Ureteroscopy : A procedure to look inside the ureter and renal pelvis to check for abnormal areas. A ureteroscope is a thin, tube-like instrument with a light and a lensfor viewing. The ureteroscope is inserted through the urethra into the bladder, ureter, and renal pelvis. A tool may be inserted through the ureteroscope to take tissue samples to be checked under a microscope for signs of disease.

  Ureteroscopy. A ureteroscope (a thin, tube-like instrument with a light and a lens for viewing) is inserted through the urethra into the ureter. The doctor looks at an image of the inside of the ureter on a computer monitor.

• Biopsy: The removal of cell or tissue samples from the urethra, bladder, and, sometimes, the prostate gland. The samples are 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 cancer formed in the urethra.
• Whether the cancer has spread through the mucosa lining the urethra to nearby tissue, to lymph nodes, or to other parts of the body.
• Whether the patient is a male or female.
• The patient's general health.
• Whether the cancer has just been diagnosed or has recurred (come back).
