Vulvar Cancer Treatment

General Information About Vulvar Cancer

Vulvar cancer is a rare disease in which malignant (cancer) cells form in the tissues of the vulva.

Vulvar cancer forms in a woman's external genitalia. The vulva includes the inner and outer lips of the vagina, the clitoris (sensitive tissue between the lips), and the opening of the vagina and its glands.

Vulvar cancer most often affects the outer vaginal lips. Less often, cancer affects the inner vaginal lips or the clitoris.

Vulvar cancer usually develops slowly over a period of years. Abnormalcells can grow on the surface of the vulvar skin for a long time. This precancerous condition is called vulvar intraepithelialneoplasia (VIN) or dysplasia. Because it is possible for VIN or dysplasia to develop into vulvar cancer, treatment of this condition is very important.

HPV infection and older age can affect the risk of developing vulvar cancer.

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 vulvar cancer include the following:

  • Having human papillomavirus (HPV) infection.
  • Older age.

Possible signs of vulvar cancer include bleeding or itching.

Vulvar cancer often does not cause early symptoms. When symptoms occur, they may be caused by vulvar cancer or by other conditions. A doctor should be consulted if any of the following problems occur:

  • A lump in the vulva.
  • Itching that does not go away in the vulvar area.
  • Bleeding not related to menstruation (periods).
  • Tenderness in the vulvar area.

Tests that examine the vulva are used to detect (find) and diagnose vulvar 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 the vulva 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.
  • Biopsy: The removal of cells or tissues from the vulva 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:

  • The stage of the cancer.
  • The patient's age and general health.
  • Whether the cancer has just been diagnosed or has recurred (come back).

Stages of Vulvar Cancer

After vulvar cancer has been diagnosed, tests are done to find out if cancer cells have spread within the vulva or to other parts of the body.

The process used to find out if cancer has spread within the vulva 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:

  • Pelvic exam: An exam of the vagina, cervix, uterus, fallopian tubes, ovaries, and rectum. The doctor or nurse 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. A speculum is also inserted into the vagina and the doctor or nurse looks at the vagina and cervix for signs of disease. A Pap test or Pap smear of the cervix is usually done. The doctor or nurse also inserts a lubricated, gloved finger into the rectum to feel for lumps or abnormal areas.

Two gloved fingers of one hand of the doctor or nurse are shown inserted into the vagina, while the other hand is shown pressing on the lower abdomen. The inset shows a woman covered by a drape on an exam table with her legs apart and her feet in stirrups.
    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.
  • Cystoscopy: A procedure to look inside the bladder and urethra to check for abnormal areas. A cystoscope (a thin, lighted tube) is inserted through the urethra into the bladder. Tissue samples may be taken for biopsy.
  • Proctoscopy: A procedure to look inside the rectum and anus to check for abnormal areas. A proctoscope (a thin, lighted tube) is inserted into the anus and rectum. Tissue samples may be taken for biopsy.
  • X-rays: 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. To stage vulvar cancer, x-rays may be taken of the organs and bones inside the chest, and the pelvic bones.
  • Intravenous pyelogram (IVP): A series of x-rays of the kidneys, ureters, and bladder to find out if cancer has spread to these organs. A contrast dye is injected into a vein. As the contrast dye moves through the kidneys, ureters and bladder, x-rays are taken to see if there are any blockages. This procedure is also called intravenous urography.
  • 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): A procedure that uses a magnet, radio waves, and a computer to make a series of detailed pictures of areas inside the body. This procedure is also called nuclear magnetic resonance imaging (NMRI).

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.

The following stages are used for vulvar cancer:

Stage 0 (Carcinoma in Situ)

In stage 0, abnormalcells are found on the surface of the vulvar skin. 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 is found in the vulva only or in the vulva and perineum (area between the rectum and the vagina). The tumor is 2 centimeters or smaller and has spread to tissue under the skin. Stage I vulvar cancer is further divided into stage IA and stage IB.

  • Stage IA: The tumor has spread 1 millimeter or less into the tissue of the vulva.
  • Stage IB: The tumor has spread more than 1 millimeter into the tissue of the vulva.

Stage II

In stage II, cancer is found in the vulva or the vulva and perineum (space between the rectum and the vagina), and the tumor is larger than 2 centimeters.

Stage III

In stage III vulvar cancer, the cancer is of any size and either:

  • is found only in the vulva or the vulva and perineum and has spread to tissue under the skin and to nearby lymph nodes on one side of the groin; or
  • has spread to nearby tissues such as the lower part of the urethra and/or vagina or anus, and may have spread to nearby lymph nodes on one side of the groin.

Stage IV

Stage IV is divided into stage IVA and stage IVB, based on where the cancer has spread.

  • Stage IVA: Cancer has spread to nearby lymph nodes on both sides of the groin, or has spread beyond nearby tissues to the upper part of the urethra, bladder, or rectum, or has attached to the pelvic bone and may have spread to lymph nodes.
  • Stage IVB: Cancer has spread to distant parts of the body.

Recurrent Vulvar Cancer

Recurrentvulvar cancer is cancer that has recurred (come back) after it has been treated. The cancer may come back in the vulva or in other parts of the body.

Treatment Option Overview

There are different types of treatment for patients with vulvar cancer.

Different types of treatments are available for patients with vulvar 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.

Four types of standard treatment are used:

Laser therapy

Laser therapy is a cancer treatment that uses a laser beam (a narrow beam of intense light) to kill cancer cells.

Surgery

Surgery is the most common treatment for cancer of the vulva. The goal of surgery is to remove all the cancer without any loss of the woman's sexual function. One of the following types of surgery may be done:

  • Wide local excision: A surgical procedure to remove the cancer and some of the normal tissue around the cancer.
  • Radical local excision: A surgical procedure to remove the cancer and a large amount of normal tissue around it. Nearby lymph nodes in the groin may also be removed.
  • Vulvectomy: A surgical procedure to remove part or all of the vulva:
    • Skinning vulvectomy: The top layer of vulvar skin where the cancer is found is removed. Skin grafts from other parts of the body may be needed to cover the area.
    • Simple vulvectomy: The entire vulva is removed.
    • Modified radical vulvectomy: The part of the vulva that contains cancer and some of the normal tissue around it are removed.
    • Radical vulvectomy: The entire vulva, including the clitoris, and nearby tissue are removed. Nearby lymph nodes may also be removed.
  • Pelvic exenteration: A surgical procedure to remove the lower colon, rectum, and bladder. The cervix, vagina, ovaries, and nearby lymph nodes are also removed. Artificial openings (stoma) are made for urine and stool to flow from the body into a collection bag.

Even if the doctor removes all the cancer that can be seen at the time of the surgery, some patients may have 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.

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, a body cavity such as the abdomen, or onto the skin, 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.

Topical chemotherapy for vulvar cancer may be applied to the skin in a cream or lotion.

See Drugs Approved to Treat Vulvar Cancer for more information.

New types of treatment are being tested in clinical trials.

Information about clinical trials is available from the NCI Web site.

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.

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. 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. 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).
