Ovarian epithelial cancer is a disease in which malignant
(cancer) cells form in the tissue covering the ovary.
The ovaries are a pair
of organs in the female reproductive
system. They are located in the pelvis, one on each side of the uterus (the hollow, pear-shaped
organ where a fetus grows). Each
ovary is about the size and shape of an almond. The ovaries produce eggs and
female hormones (chemicals that
control the way certain cells or
organs function).
Ovarian epithelial cancer is one type of cancer that affects the
ovary. (See the PDQ treatment summaries on Ovarian Germ Cell Tumors 1 and Ovarian Low Malignant Potential Tumors 2 for information about other types of ovarian cancer.)
Women who have a family history of ovarian cancer are at an
increased risk of developing ovarian cancer.
Anything that increases your risk of getting a disease is called a risk factor. Women who have one first-degree relative (mother, daughter, or
sister) with ovarian cancer are at an increased risk of developing ovarian
cancer. This risk is higher in women who have one first-degree relative and one
second-degree relative (grandmother or aunt) with ovarian cancer. This risk is
even higher in women who have two or more first-degree relatives with ovarian
cancer.
Some ovarian cancers are caused by inherited gene mutations
(changes).
The genes in cells carry the hereditary information
that is received from a person’s parents. Hereditary ovarian cancer makes up approximately
5% to 10% of all cases of ovarian cancer. Three hereditary patterns have been
identified: ovarian cancer alone, ovarian and breast cancers, and ovarian and colon cancers.
Tests that can detect mutated genes have been developed. These genetic tests are sometimes done for
members of families with a high risk of cancer. (See the PDQ summaries on Ovarian Cancer Screening 3, Ovarian Cancer Prevention 4, and Genetics of Breast and Ovarian Cancer 5 for
more information.)
Women with an increased risk of ovarian cancer may consider
surgery to prevent it.
Some women who have an increased risk of ovarian
cancer may choose to have a prophylactic
oophorectomy (the removal of healthy ovaries so that cancer
cannot grow in them). In high-risk women, this procedure has been shown to greatly decrease the risk of developing ovarian cancer. (See the PDQ summary on Ovarian Cancer Prevention 4 for more information.)
Possible signs of ovarian cancer include pain or swelling in the abdomen.
Early ovarian cancer may not cause any symptoms. When symptoms do appear, ovarian cancer is often advanced. Symptoms of ovarian cancer may include the following:
These symptoms may be caused by other conditions and not by ovarian cancer. If the symptoms get worse or do not go away on their own, a doctor should be consulted so that any problem can be diagnosed and treated as early as possible. When found in its early stages, ovarian epithelial cancer can often be cured.
Women with any stage of ovarian cancer should think about taking part in a clinical trial. Information about ongoing clinical trials is available from the NCI Web site 6.
Tests that examine the ovaries, pelvic area, blood, and ovarian
tissue are used to detect (find) and diagnose ovarian cancer.
The following tests and procedures may be used:
- 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 the other hand is placed 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.
- Ultrasound exam: A procedure in which high-energy sound waves (ultrasound) are bounced off internal tissues or organs and make echoes. The echoes form a picture of body tissues called a sonogram.
- CA 125 assay: A test that measures the level of CA 125 in the blood. CA 125 is a substance released by cells into the bloodstream. An increased CA 125 level is sometimes a sign of cancer or other condition.
- Barium enema: A series of x-rays of the lower gastrointestinal tract. A liquid that contains barium (a silver-white metallic compound) is put into the rectum. The barium coats the lower gastrointestinal tract and x-rays are taken. This procedure is also called a lower GI series.
- 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.
- 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.
- Biopsy: The removal of cells or tissues so they can be viewed under a microscope by a pathologist to check for signs of cancer. The tissue is removed in a procedure
called a laparotomy (a surgical incision made in the wall of the
abdomen).
Certain factors affect treatment options and prognosis
(chance of recovery).
The prognosis (chance of recovery) and treatment options depend on the following:
- The stage
of the cancer.
- The type and size of the tumor.
- The
patient’s age and general health.
- Whether the cancer has just been diagnosed or has recurred (come back).
Stages of Ovarian Epithelial Cancer
Key Points for This Section
|
|
After ovarian epithelial cancer has been diagnosed,
tests are done to find out if cancer cells have spread within the ovaries or to
other parts of the body.
The process used to find out if cancer has spread within the ovary 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.
An operation called a laparotomy is usually done to find
out the stage of the disease. A doctor must cut into the abdomen and carefully look at all
the organs to see if they contain cancer. The doctor will also perform a biopsy (cut out small pieces of tissue so they can be looked at under a microscope to
see whether they contain cancer). Usually the doctor will remove the cancer and
organs that contain cancer during the laparotomy. (See the Treatment
Options by Stage 7 section.)
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 ovarian epithelial
cancer:
Stage I
In stage I, cancer is
found in one or both of the ovaries. Stage I is divided into stage IA, stage IB, and stage IC.
Stage II
In stage II, cancer is
found in one or both ovaries and has spread into other areas of the pelvis. Stage II is divided
into stage IIA, stage IIB, and stage IIC.

Pea, peanut, walnut, and lime show tumor sizes. |
Stage III
In stage III, cancer is found in one or both ovaries and has spread to other parts of the abdomen.
Stage III is divided into stage IIIA, stage IIIB, and stage IIIC.
Cancer that has spread to the surface of the liver is also considered stage III disease.
Stage IV
In stage IV, cancer is
found in one or both ovaries and has metastasized (spread) beyond the abdomen to other
parts of the body.
Cancer that has spread to tissues in the liver is also considered stage IV disease.
Recurrent or Persistent Ovarian Epithelial Cancer
Recurrent ovarian
epithelial cancer is cancer that has recurred (come back) after it has been
treated. Persistent cancer is cancer that does not go away with treatment. Treatment Option Overview
Key Points for This Section
|

There are different types of treatment for patients with ovarian epithelial
cancer.
Different types of treatment are available for patients with ovarian epithelial cancer. Some
treatments are standard, 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 treatment
currently used as 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.
Three kinds of standard treatment are used. These include the
following:
Surgery
Most patients have surgery to remove as much of the tumor as possible. Different types
of surgery may include:
Radiation therapy
Radiation therapy is a cancer treatment that uses high-energy x-rays or other types of radiation to kill cancer cells or keep them from growing. 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.
Some women receive a treatment called intraperitoneal radiation therapy,
in which radioactive liquid is put directly in the abdomen through a catheter.
Chemotherapy
Chemotherapy is a cancer treatment that uses drugs to stop the growth of cancer cells, either by killing the cells or by stopping them 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).
A type of regional chemotherapy used to treat ovarian cancer is intraperitoneal (IP) chemotherapy. In IP chemotherapy, the anticancer drugs are carried directly into the peritoneal cavity (the space that contains the abdominal organs) through a thin tube.
Treatment with more than one anticancer drug is called combination chemotherapy.
The way the chemotherapy is given depends on the type and stage of the cancer being treated.
New types of treatment are being tested in clinical
trials.
This summary section describes treatments that are being studied in clinical trials. It may not mention every new treatment being studied. Information about clinical trials is available from the NCI Web site 6.
Biologic therapy
Biologic therapy is a treatment that uses the patient’s immune system to fight cancer. Substances made by the body or made in a laboratory are used to boost, direct, or restore the body’s natural defenses against cancer. This type of cancer treatment is also called biotherapy or immunotherapy.
Targeted therapy
Targeted therapy is a type of treatment that uses drugs or other substances to identify and attack specific cancer cells without harming normal cells.
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 clinical trials database.
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.
Treatment Options by Stage
A link to a list of current clinical trials is included for each treatment section. For some types or stages of cancer, there may not be any trials listed. Check with your doctor for clinical trials that are not listed here but may be right for you.
Stage I and II Ovarian Epithelial Cancer
Treatment of stage I and stage II ovarian epithelial
cancer may include the following:
Check for U.S. clinical trials from NCI's PDQ Cancer Clinical Trials Registry that are now accepting patients with stage I ovarian epithelial cancer 8 and stage II ovarian epithelial cancer 9. For more specific results, refine the search by using other search features, such as the location of the trial, the type of treatment, or the name of the drug. General information about clinical trials is available from the NCI Web site 10.
Stage III and IV Ovarian Epithelial Cancer
Treatment of stage III and stage IV ovarian
epithelial cancer may be surgery to remove the tumor, total abdominal hysterectomy, bilateral
salpingo-oophorectomy, and omentectomy. After surgery, treatment depends on how much tumor remains.
When the tumor that remains is 1 centimeter or smaller, treatment is usually combination chemotherapy, including intraperitoneal (IP) chemotherapy.
When the tumor that remains is larger than 1 centimeter, treatment may include the following:
Check for U.S. clinical trials from NCI's PDQ Cancer Clinical Trials Registry that are now accepting patients with stage III ovarian epithelial cancer 11 and stage IV ovarian epithelial cancer 12. For more specific results, refine the search by using other search features, such as the location of the trial, the type of treatment, or the name of the drug. General information about clinical trials is available from the NCI Web site 10.
Treatment Options for Recurrent or Persistent Ovarian Epithelial Cancer
Treatment of recurrent ovarian epithelial cancer may include the following:
Check for U.S. clinical trials from NCI's PDQ Cancer Clinical Trials Registry that are now accepting patients with recurrent ovarian epithelial cancer 13. For more specific results, refine the search by using other search features, such as the location of the trial, the type of treatment, or the name of the drug.

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 30. Descriptions of the trials are available in health professional and patient versions.

Cancer that began in tissue covering the ovary and has spread from one or both ovaries into other areas of the pelvis. Stage II is divided into stages IIA, IIB, and IIC. In stage IIA, cancer has spread to the uterus and/or the fallopian tubes. In stage IIB, cancer has spread to other tissues within the pelvis. In stage IIC, cancer has spread to the uterus and/or fallopian tubes and/or other tissue within the pelvis and cancer cells are found in fluid from the peritoneal cavity (the body cavity that contains most of the organs in the abdomen).
stage III ovarian epithelial cancer (...oh-VAYR-ee-un EH-pih-THEE-lee-ul KAN-ser)
