General Information About Endometrial Cancer

Key Points for This Section

Endometrial cancer is a disease in which malignant (cancer) cells form in the tissues of the endometrium. Taking tamoxifen for breast cancer or taking estrogen alone (without progesterone) can affect the risk of developing endometrial cancer. Possible signs of endometrial cancer include unusual vaginal discharge or pain in the pelvis. Tests that examine the endometrium are used to detect (find) and diagnose endometrial cancer. Certain factors affect prognosis (chance of recovery) and treatment options.

Endometrial cancer is a disease in which malignant (cancer) cells form in the tissues of the endometrium.

The endometrium is the lining of the uterus, a hollow, muscular organ in a woman’s pelvis. The uterus is where a fetus grows. In most nonpregnant women, the uterus is about 3 inches long. The lower, narrow end of the uterus is the cervix, which leads to the vagina.

Cancer of the endometrium is different from cancer of the muscle of the uterus, which is called sarcoma of the uterus. Refer to the PDQ summary on Uterine Sarcoma Treatment ¹ for more information.

Taking tamoxifen for breast cancer or taking estrogen alone (without progesterone) can affect the risk of developing endometrial cancer.

Endometrial cancer may develop in breast cancer patients who have been treated with tamoxifen. A patient taking this drug should have a pelvic exam every year and report any vaginal bleeding (other than menstrual bleeding) as soon as possible. Women taking estrogen (a hormone that can affect the growth of some cancers) alone have an increased risk of developing endometrial cancer. Taking estrogen in combination with progesterone (another hormone) does not increase a woman’s risk of this cancer.

Possible signs of endometrial cancer include unusual vaginal discharge or pain in the pelvis.

These and other symptoms may be caused by endometrial cancer. Other conditions may cause the same symptoms. A doctor should be consulted if any of the following problems occur:

• Bleeding or discharge not related to menstruation (periods).
• Difficult or painful urination.
• Pain during sexual intercourse.
• Pain in the pelvic area.

Tests that examine the endometrium are used to detect (find) and diagnose endometrial cancer.

Because endometrial cancer begins inside the uterus, it does not usually show up in the results of a Pap test. For this reason, a sample of endometrial tissue must be removed and examined under a microscope to look for cancer cells. One of the following procedures may be used:

• Endometrial biopsy: The removal of tissue from the endometrium (inner lining of the uterus) by inserting a thin, flexible tube through the cervix and into the uterus. The tube is used to gently scrape a small amount of tissue from the endometrium and then remove the tissue samples. A pathologist views the tissue under a microscope to look for cancer cells.
• Dilatation and curettage: A surgical procedure to remove samples of tissue or the inner lining of the uterus. The cervix is dilated and a curette (spoon-shaped instrument) is inserted into the uterus to remove tissue. Tissue samples may be taken for biopsy. This procedure is also called a D&C.

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 (whether it is in the endometrium only, involves the whole uterus, or has spread to other places in the body).
• How the cancer cells look under a microscope.
• Whether the cancer cells are affected by progesterone.

Endometrial cancer is highly curable.

Stages of Endometrial Cancer

Key Points for This Section

After endometrial cancer has been diagnosed, tests are done to find out if cancer cells have spread within the uterus or to other parts of the body. The following stages are used for endometrial cancer: Stage I Stage II Stage III Stage IV

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

The process used to find out whether the cancer has spread within the uterus 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. Certain tests and procedures are used in the staging process. A hysterectomy (an operation in which the uterus is removed) will usually be done to help find out how far the cancer has spread.

The following stages are used for endometrial cancer:

Stage I

In stage I, cancer is found in the uterus only. Stage I is divided into stages IA, IB, and IC, based on how far the cancer has spread.

• Stage IA: Cancer is in the endometrium only.
• Stage IB: Cancer has spread into the inner half of the myometrium (muscle layer of the uterus).
• Stage IC: Cancer has spread into the outer half of the myometrium.

Stage II

In stage II, cancer has spread from the uterus to the cervix, but has not spread outside the uterus. Stage II is divided into stages IIA and IIB, based on how far the cancer has spread into the cervix.

• Stage IIA: Cancer has spread to the glands where the cervix and uterus meet.
• Stage IIB: Cancer has spread into the connective tissue of the cervix.

Stage III

In stage III, cancer has spread beyond the uterus and cervix, but has not spread beyond the pelvis. Stage III is divided into stages IIIA, IIIB, and IIIC, based on how far the cancer has spread within the pelvis.

• Stage IIIA: Cancer has spread to one or more of the following:
  • the outermost layer of the uterus; or
  • tissue just beyond the uterus; or
  • the peritoneum.
• Stage IIIB: Cancer has spread beyond the uterus and cervix, into the vagina.
• Stage IIIC: Cancer has spread to lymph nodes near the uterus.

Stage IV

In stage IV, cancer has spread beyond the pelvis. Stage IV is divided into stages IVA and IVB, based on how far the cancer has spread.

• Stage IVA: Cancer has spread to the bladder and/or bowel wall.
• Stage IVB: Cancer has spread to other parts of the body beyond the pelvis, including lymph nodes in the abdomen and/or groin.

Recurrent Endometrial Cancer

Recurrent endometrial cancer is cancer that has recurred (come back) after it has been treated. The cancer may come back in the pelvis, in lymph nodes in the abdomen, or in other parts of the body.

Treatment Option Overview

Key Points for This Section

There are different types of treatment for patients with endometrial cancer. Four types of standard treatment are used: Surgery Chemotherapy Radiation therapy Hormone therapy New types of treatment are being tested in clinical trials.

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

Different types of treatment are available for patients with endometrial cancer. Some treatments are standard (the currently used treatment), and some are being tested in clinical trials. Before starting treatment, patients may want to think about taking part in a clinical trial. 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.

Clinical trials are taking place in many parts of the country. Information about ongoing clinical trials is available from the NCI Web site ². Choosing the most appropriate cancer treatment is a decision that ideally involves the patient, family, and health care team.

Four types of standard treatment are used:

Surgery

Surgery (removing the cancer in an operation) is the most common treatment for endometrial cancer. The following surgical procedures may be used:

• Total hysterectomy: A surgical procedure to remove the uterus, including the cervix. If the uterus and cervix are taken out through the vagina, the operation is called a vaginal hysterectomy. If the uterus and cervix are taken out through a large incision (cut) in the abdomen, the operation is called a total abdominal hysterectomy. If the uterus and cervix are taken out through a small incision (cut) in the abdomen using a laparoscope, the operation is called a total laparoscopic hysterectomy.
• Bilateral salpingo-oophorectomy: A surgical procedure to remove both ovaries and both fallopian tubes.
• Radical hysterectomy: A surgical procedure to remove the uterus, cervix, and part of the vagina. The ovaries, fallopian tubes, or nearby lymph nodes may also be removed.

Even if the doctor removes all the cancer that can be seen at the time of the surgery, some patients may be given radiation therapy or hormone treatment after surgery to kill any cancer cells that are left. Treatment given after the surgery, to increase the chances of a cure, is called adjuvant therapy.

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 spinal column, an organ, or a body cavity such as the abdomen, 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.

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.

Hormone therapy

Hormone therapy is a cancer treatment that removes hormones or blocks their action and stops cancer cells from growing. Hormones are substances produced by glands in the body and circulated in the bloodstream. The presence of some hormones can cause certain cancers to grow. If tests show that the cancer cells have places where hormones can attach (receptors), drugs, surgery, or radiation therapy are used to reduce the production of hormones or block them from working.

New types of treatment are being tested in clinical trials.

Information about ongoing clinical trials is available from the NCI Web site. ²

Treatment Options by Stage

Stage I Endometrial Cancer

Treatment of stage I endometrial cancer may include the following:

• Surgery (total abdominal hysterectomy and bilateral salpingo-oophorectomy). Lymph nodes in the pelvis and abdomen may also be removed for examination under a microscope to check for cancer cells.

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 ⁹. 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 ¹¹. 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); TTY at 1-800-332-8615.

The extent of a cancer in the body. Staging is usually based on the size of the tumor, whether lymph nodes contain cancer, and whether the cancer has spread from the original site to other parts of the body.

Cancer is found in the uterus only. Stage I is divided into stage IA, IB, and IC, based on how far the disease has spread. In stage IA, cancer is in the endometrium only; in stage IB, cancer has spread into the inner half of the myometrium (muscle layer of the uterus); in stage IC, cancer has spread into the outer half of the myometrium.

Cancer has spread from the uterus to the cervix, but not beyond the cervix. Stage II is divided into stage IIA and IIB, based on how far the cancer has spread into the cervix. In stage IIA, cancer has spread to the glands where the cervix and uterus meet. In stage IIB, cancer has spread into the connective tissue of the cervix.

Cancer has spread beyond the uterus and cervix, but has not spread beyond the pelvis. Stage III is divided into stage IIIA, IIIB, and IIIC, based on how far the cancer has spread within the pelvis. In stage IIIA, cancer has spread to (1) the outermost layer of the uterus; and/or (2) tissue just beyond the uterus; and/or (3) the peritoneum (tissue that lines the abdominal wall and organs). In stage IIIB, cancer has spread beyond the uterus and cervix, into the vagina. In stage IIIC, cancer has spread to lymph nodes near the uterus.

Cancer has spread beyond the pelvis. Stage IV is divided into stage IVA and IVB, based on how far the cancer has spread. In stage IVA, cancer has spread to the bladder or bowel wall. In stage IVB, cancer has spread to other parts of the body beyond the pelvis, including lymph nodes in the abdomen and/or groin.

Performing exams and tests to learn the extent of the cancer within the body, especially whether the disease has spread from the original site to other parts of the body. It is important to know the stage of the disease in order to plan the best treatment.

Treatment with anticancer drugs that travel through the blood to cells all over the body.

A drug used to treat certain types of breast cancer in women and men. It is also used to prevent breast cancer in women who have had ductal carcinoma in situ (abnormal cells in the ducts of the breast) and are at a high risk of developing breast cancer. Tamoxifen is also being studied in the treatment of other types of cancer. It blocks the effects of the hormone estrogen in the breast. Tamoxifen is a type of antiestrogen. Also called tamoxifen citrate and Nolvadex.

Treatment.

A group or layer of cells that work together to perform a specific function.
