Vaginal Cancer Treatment
Stages of Vaginal Cancer
Key Points for this Section
After vaginal cancer has been diagnosed, tests are done to find out if cancer cells have spread within the vagina or to other parts of the body.
The process used to find out if cancer has spread within the vagina 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:
- Chest x-ray: An x-ray of the organs and bones inside the chest. 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.
- 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).
- PET scan (positron emission tomography scan): A procedure to find malignant tumor cells in the body. A small amount of radioactive glucose (sugar) is injected into a vein. The PET scanner rotates around the body and makes a picture of where glucose is being used in the body. Malignant tumor cells show up brighter in the picture because they are more active and take up more glucose than normal cells do.
- Cystoscopy: A procedure to look inside the bladder and urethra to check for abnormal areas. A cystoscope is inserted through the urethra into the bladder. A cystoscope is a thin, tube-like instrument with a light and a lens for viewing. It may also have a tool to remove tissue samples, which are checked under a microscope for signs of cancer.Cystoscopy. A cystoscope (a thin, tube-like instrument with a light and a lens for viewing) is inserted through the urethra into the bladder. Fluid is used to fill the bladder. The doctor looks at an image of the inner wall of the bladder on a computer monitor.
- Ureteroscopy: A procedure to look inside the ureters to check for abnormal areas. A ureteroscope is inserted through the bladder and into the ureters. A ureteroscope is a thin, tube-like instrument with a light and a lens for viewing. It may also have a tool to remove tissue to be checked under a microscope for signs of disease. A ureteroscopy and cystoscopy may be done during the same procedure.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.
- Proctoscopy: A procedure to look inside the rectum to check for abnormal areas. A proctoscope is inserted through the rectum. A proctoscope is a thin, tube-like instrument with a light and a lens for viewing. It may also have a tool to remove tissue to be checked under a microscope for signs of disease.
- Biopsy: A biopsy may be done to find out if cancer has spread to the cervix. A sample of tissue is cut from the cervix and viewed under a microscope. A biopsy that removes only a small amount of tissue is usually done in the doctor’s office. A woman may need to go to a hospital for a cone biopsy (removal of a larger, cone-shaped piece of tissue from the cervix and cervical canal). A biopsy of the vulva may also be done to see if cancer has spread there.
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 vaginal cancer:
Stage 0 (Carcinoma in Situ)
In stage 0, abnormal cells are found in tissue lining the
inside of the vagina. These abnormal cells may become cancer and spread into nearby normal tissue. Stage 0 is also called carcinoma in situ.
In stage I, cancer has formed and
is found in the vagina only.
In stage II, cancer has spread from the vagina to the tissue around the vagina.
In stage III, cancer has spread from the vagina to the lymph nodes in the pelvis or groin, or to the pelvis, or both.
Stage IV is divided into stage IVA and stage IVB:
