Penile Cancer
Description of Penile Cancer
Cancer of the penis, a rare kind of cancer in the United States, is a disease in which cancer (malignant) cells are found on the skin and in the tissues of the penis.
Men who are not circumcised at birth may have a higher risk for getting cancer of the penis. A circumcision is an operation in which the doctor takes away part or all of the foreskin from the penis. The foreskin is the skin which covers the tip of the penis. A circumcision is done on many baby boys before they go home from the hospital.
Like most cancers, cancer of the penis is best treated when it is found (diagnosed) early. You should see a doctor if you have any of the following problems: growths or sores on your penis, any unusual liquid coming from your penis (abnormal discharge), or bleeding.
If you have symptoms of cancer, your doctor will examine your penis and feel for any lumps. If the penis doesn't look normal or if your doctor feels any lumps, a small sample of tissue (called a biopsy) will be cut from the penis and looked at under a microscope to see if there are any cancer cells.
Your prognosis (chance of recovery) and choice of treatment depend on the stage of your cancer (whether it is just in the penis or has spread to other places), and your general state of health.
Stages Of Cancer Of The Penis
Once cancer of the penis is found, more tests will be done to find out if the cancer has spread from the penis to other parts of the body (staging). Your doctor needs to know the stage of your disease to plan treatment. The following stages are used for cancer of the penis:
Stage I
Cancer cells are found only on the surface of the glans (the head of the penis) and on the foreskin (the loose skin that covers the head of the penis).
Stage II
Cancer cells are found in the deeper tissues of the glans and have spread to the shaft of the penis (the long, slender cylinders of tissue inside the penis that contain spongy tissue and expand to produce erections).
Stage III
Cancer cells are found in the penis and have spread to nearby lymph nodes in the groin. (Lymph nodes are small bean-shaped structures that are found throughout the body; they produce and store infection-fighting cells).
Stage IV
Cancer cells are found throughout the penis and the lymph nodes in the groin and/or have spread to other parts of the body.
Recurrent
Recurrent disease means that the cancer has come back (recurred) after it has been treated. It may come back in the same area or in another place.
How Cancer Of The Penis Is Treated
There are treatments for all patients with cancer of the penis. Four kinds of treatment are used:
surgery (taking out the cancer in an operation) radiation therapy (using high-dose x-rays or other high-energy rays to kill cancer cells and shrink tumors) chemotherapy (using drugs to kill the cancer cells) biological therapy (using your immune system to fight cancer).
Surgery is the most common treatment for all stages of cancer of the penis. Your doctor may take out the cancer using one of the following operations:
Wide local excision takes out only the cancer and some normal tissue on either side.
Microsurgery is an operation that removes the cancer and as little normal tissue as possible. During this surgery, the doctor uses a microscope to look at the cancerous area to make sure all the cancer cells are removed.
Laser surgery uses a narrow beam of light to remove cancer cells.
Circumcision is an operation that removes the foreskin.
Amputation of the penis is an operation that takes out the penis. It is the most common and most effective treatment for cancer of the penis. In a partial penectomy, part of the penis is taken out. In a total penectomy, the whole penis is removed. Lymph nodes in the groin may be taken out
during surgery.
Radiation therapy uses x-rays or other high-energy rays to kill cancer cells and shrink tumors. Radiation may come from a machine outside the body (external radiation) or from putting materials that contain radiation through thin plastic tubes into the area where the cancer cells are (internal
radiation). Radiation may be used alone or after surgery.
Chemotherapy uses drugs to kill cancer cells. Fluorouracil cream (achemotherapy drug put on the skin of the penis) is sometimes used for very small surface cancers of the penis. Chemotherapy may also be given by pill or by a needle in a vein. When chemotherapy is given in this way, it is called a
systemic treatment because the drugs enter the bloodstream, travel through the body, and can kill cancer cells outside the penis.
Biological therapy tries to get your own body to fight cancer. It uses materials made by your own body or made in a laboratory to boost, direct, or restore your body's natural defenses against disease. Biological treatment is sometimes called biological response modifier (BRM) therapy.
Treatment By Stage
Treatment for cancer of the penis depends on the stage of your disease, the type of disease, your age, and your overall condition.
You may receive treatment that is considered standard based on its effectiveness in a number of patients in past studies, or you may choose to go into a clinical trial. Not all patients are cured with standard therapy and some standard treatments may have more side effects than are desired. For
these reasons, clinical trials are designed to find better ways to treat cancer patients and are based on the most up-to-date information. Clinical trials are going on in many parts of the country for most stages of cancer of the penis.
STAGE I PENILE CANCER
If your cancer is limited to the foreskin, your treatment will probably be wide local excision and circumcision.
If your cancer begins in the glans and does not involve other tissues, your treatment may involve:
Fluorouracil cream. Microsurgery
If your tumor begins in the glans and involves other tissues, your treatment may involve: Amputation of the penis (partial penectomy). Lymph nodes in the groin may also be removed. External radiation therapy. Microsurgery
Clinical trials of laser therapy for stage I penile cancer are also being conducted.
STAGE II PENILE CANCER
Your treatment may be amputation of the penis (partial, total, or radical penectomy) or radiation therapy followed by amputation of the penis. Clinical trials of laser therapy for stage II penile cancer are also being conducted.
STAGE III PENILE CANCER
Your treatment may be amputation of the penis, followed by removal of lymph nodes on both sides of the groin or amputation of the penis followed by radiation therapy. Clinical trials of chemotherapy and chemotherapy with radiation therapy are also being conducted.
STAGE IV PENILE CANCER
Your treatment will be designed to reduce your symptoms and may include wide local excision, microsurgery, amputation of the penis, or radiation therapy. Clinical trials of chemotherapy combined with surgery or radiation therapy are also being conducted.
RECURRENT PENILE CANCER
If the cancer has come back (recurred), your treatment may include amputation of the penis or radiation therapy. Clinical trials of chemotherapy or biological therapy are also being conducted.
