What is cancer of the vagina?
Cancer of the vagina, a rare kind of cancer in women, is a disease in which
cancer (malignant) cells are found in the tissues of the vagina. The vagina is
the passageway through which fluid passes out of the body during menstrual
periods and through which a woman has babies. It is also called the "birth
canal." The vagina connects the cervix (the opening of the womb or uterus) and
the vulva (the folds of skin around the opening to the vagina).
There are two types of cancer of the vagina: squamous cell cancer (squamous
carcinoma) and adenocarcinoma. Squamous carcinoma is usually found in women
between the ages of 60 and 80. Adenocarcinoma is more often found in women
between the ages of 12 and 30.
Young women whose mothers took DES (diethylstilbestrol) are at risk for getting
tumors in their vaginas. Some of them get a rare form of cancer called clear
cell adenocarcinoma. The drug DES was given to pregnant women between 1945 and
1970 to keep them from losing their babies (miscarriage).
A doctor should be seen if there are any of the following:
- Bleeding or
discharge not related to menstrual periods.
- Difficult or painful urination.
- Pain during intercourse or in the pelvic area.
- Also, there is still a chance
of developing vaginal cancer in women who have had a hysterectomy.
A doctor may use several tests to see if there is cancer. The doctor will
usually begin by giving the patient an internal (pelvic) examination. The
doctor will feel for lumps and will then do a Pap smear. Using a piece of
cotton, a brush, or a small wooden stick, the doctor will gently scrape the
outside of the cervix and vagina in order to pick up cells. Some pressure may
be felt, but usually with no pain.
If cells that are not normal are found, the doctor will need to cut a small
sample of tissue (called a biopsy) out of the vagina and look at it under a
microscope to see if there are any cancer cells. The doctor should look not
only at the vagina, but also at the other organs in the pelvis to see where the
cancer started and where it may have spread. The doctor may take an x-ray of
the chest to make sure the cancer has not spread to the lungs.
The chance of recovery (prognosis) and choice of treatment depend on the stage
of the cancer (whether it is just in the vagina or has spread to other places)
and the patient's general state of health.

Stage Explanation

Stages of cancer of the vagina
Once cancer of the vagina has been found (diagnosed), more tests will be done
to find out if the cancer has spread from the vagina to other parts of the body
(staging). A doctor needs to know the stage of the disease to plan treatment.
The following stages are used for cancer of the vagina:
[Back to top]
Stage 0 or carcinoma in situ
Stage 0 cancer of the vagina is a very early cancer. The cancer is found
inside the vagina only and is in only a few layers of cells.
[Back to top]
Stage I
Cancer is found in the vagina, but has not spread outside of it.
[Back to top]
Stage II
Cancer has spread to the tissues just outside the vagina, but has not gone to
the bones of the pelvis.
[Back to top]
Stage III
Cancer has spread to the bones of the pelvis. Cancer cells may also have
spread to other organs and the lymph nodes in the pelvis. (Lymph nodes are
small bean-shaped structures that are found throughout the body. They produce
and store cells that fight infection.)
[Back to top]
Stage IVA
Cancer has spread into the bladder or rectum.
[Back to top]
Stage IVB
Cancer has spread to other parts of the body, such as the lungs.

Recurrent
Recurrent disease means that the cancer has come back (recurred) after it has
been treated. It may come back in the vagina or in another place.

Treatment Option Overview

How cancer of the vagina is treated
Treatments are available for all patients with cancer of the vagina. There are
three kinds of treatment:
- 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 cancer cells).
Surgery is the most common treatment of all stages of cancer of the vagina. A
doctor may take out the cancer using one of the following:
- Laser surgery uses a narrow beam of light to kill cancer cells and is
useful for stage 0 cancer.
- Wide local excision takes out the cancer and some of the tissue around it.
A patient may need to have skin taken from another part of the body
(grafted) to repair the vagina after the cancer has been taken out.
- An operation in which the vagina is removed (vaginectomy) is sometimes
done. When the cancer has spread outside the vagina, vaginectomy may be
combined with surgery to take out the uterus, ovaries, and fallopian tubes
(radical hysterectomy). During these operations, lymph nodes in the pelvis
may also be removed (lymph node dissection).
- If the cancer has spread outside the vagina and the other female organs,
the doctor may take out the lower colon, rectum, or bladder (depending on
where the cancer has spread) along with the cervix, uterus, and vagina
(exenteration).
- A patient may need skin grafts and plastic surgery to make an artificial
vagina after these operations.
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 produce radiation
(radioisotopes) through thin plastic tubes into the area where the cancer cells
are found (internal radiation). Radiation may be used alone or after surgery.
Chemotherapy uses drugs to kill cancer cells. Chemotherapy may be taken by
pill, or it may be put into the body by a needle in a vein. Chemotherapy is
called a systemic treatment because the drugs enter the bloodstream, travel
through the body, and can kill cancer cells outside the vagina. In treating
vaginal cancer, chemotherapy may also be put directly into the vagina itself,
which is called intravaginal chemotherapy.

Treatment by stage
Treatment of cancer of the vagina depends on the stage of the disease, the type
of disease, and the patient's age and overall condition.
Standard treatment may be considered because of its effectiveness in patients
in past studies, or participation in a clinical trial may be considered. 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 ongoing in most parts of the
country for most stages of cancer of the vagina. To learn more about clinical
trials, call the Cancer Information Service at 1-800-4-CANCER (1-800-422-6237);

Stage 0 Vaginal Cancer
Treatment may be one of the following:
- Surgery to remove all or part of the vagina (vaginectomy). This may be
followed by skin grafting to repair damage done to the vagina.
- Internal radiation therapy.
- Laser surgery.
- Intravaginal chemotherapy.

Stage I Vaginal Cancer
Treatment of stage I cancer of the vagina depends on whether a patient has
squamous cell cancer or adenocarcinoma.
If squamous cancer is found, treatment may be one of the following:
- Internal radiation therapy with or without external beam radiation
therapy.
- Wide local excision. This may be followed by the rebuilding of thevagina. Radiation therapy following surgery may also be performed in
some cases.
- Surgery to remove the vagina with or without lymph nodes in the pelvic
area (vaginectomy and lymph node dissection).
If adenocarcinoma is found, treatment may be one of the following:
- Surgery to remove the vagina (vaginectomy) and the uterus, ovaries, and
fallopian tubes (hysterectomy). The lymph nodes in the pelvis are also
removed (lymph node dissection). This may be followed by the rebuilding
of the vagina. Radiation therapy following surgery may also be
performed in some cases.
- Internal radiation therapy with or without external beam radiation therapy.
- In selected patients, wide local excision and removal of some of the
lymph nodes in the pelvis followed by internal radiation.

Stage II Vaginal Cancer
Treatment of stage II cancer of the vagina is the same whether a patient has
squamous cell cancer or adenocarcinoma.
Treatment may be one of the following:
- Combined internal and external radiation therapy.
- Surgery, which may be followed by radiation therapy.
[Back to top]
Stage III Vaginal Cancer
Treatment of stage III cancer of the vagina is the same whether a patient has
squamous cell cancer or adenocarcinoma.
Treatment may be one of the following:
- Combined internal and external radiation therapy.
- Surgery may sometimes be combined with radiation therapy.
[Back to top]
Stage IVA Vaginal Cancer
Treatment of stage IVA cancer of the vagina is the same whether a patient has
squamous cell cancer or adenocarcinoma.
Treatment may be one of the following:
- Combined internal and external radiation therapy.
- Surgery may sometimes be combined with radiation therapy.
[Back to top]
Stage IVB Vaginal Cancer
If stage IVB cancer of the vagina is found, treatment may be radiation to
relieve symptoms such as pain, nausea, vomiting, or abnormal bowel function.
Chemotherapy may also be performed. A patient may also choose to participate
in a clinical trial.
[Back to top]
Recurrent Vaginal Cancer
If the cancer has come back (recurred) and spread past the female organs, a
doctor may take out the cervix, uterus, lower colon, rectum, or bladder
(exenteration), depending on where the cancer has spread. The doctor may give
the patient radiation therapy or chemotherapy.
A patient may also choose to participate in a clinical trial of chemotherapy or
radiation therapy.
