Medication
In some types of cancer, the level of a tumor marker reflects the stage (extent) of the disease and/or the patient’s prognosis (likely outcome or course of disease). More information about cancer staging is available on the Staging page. Tumor markers may also be measured periodically during cancer therapy.
Procedures
[Tumor markers in uterine cancers] In diagnosing uterine cancers, cells and tissue samples can be directly obtained from the lesion. Cytologic and histologic investigation is the best method for screening and early detection of primary uterine cancers. Tumor markers may be useful for monitoring the clinical course of therapy and earl …
Therapy
Tumor marker levels may be measured before treatment to help doctors plan the appropriate therapy. In some types of cancer, the level of a tumor marker reflects the stage (extent) of the disease and/or the patient’s prognosis (likely outcome or course of disease).
Nutrition
The main worry with tumor markers is that they are not specific enough – they have too many false positives. This means that the level is elevated, when no cancer is present. This leads to costly tests that are not needed and causes the patient to be worried.
What do tumor markers tell you about cancer?

Why are tumor marker levels measured before treatment?
Should you be worried about tumor markers?
What do markers mean in cancer treatment?
A tumor marker is anything present in or produced by cancer cells or other cells of the body in response to cancer or certain benign (noncancerous) conditions that provides information about a cancer, such as how aggressive it is, what kind of treatment it may respond to, or whether it is responding to treatment.
What is the tumor marker for uterine cancer?
As individual tumor marker, serum CA 125 has the ability to detect endometrial cancer in patients with abnormal uterine bleeding.
How tumor markers are of use in treatment monitoring?
Introduction. Tumor markers may be defined as molecules which indicate the presence of cancer or provide information about the likely future behavior of a cancer (i.e., likelihood of progression or response to therapy) [1,2]. In asymptomatic subjects, tumor markers are potentially used in screening for early malignancy ...
Are there blood markers for uterine cancer?
CA-125 blood test. CA-125 is a substance released into the bloodstream by many, but not all, endometrial and ovarian cancers. If a woman has endometrial cancer, a very high blood CA-125 level suggests that the cancer has likely spread beyond the uterus. Some doctors check CA-125 levels before surgery or other treatment ...
What is the normal range for cancer markers?
Normal range: < 2.5 ng/ml. Normal range may vary somewhat depending on the brand of assay used. Levels > 10 ng/ml suggest extensive disease and levels > 20 ng/ml suggest metastatic disease.
What happens if your endometrial biopsy is positive?
Biopsy results may show cell changes linked to hormone levels, or abnormal tissues, such as fibroids or polyps. These can lead to abnormal bleeding. Your provider can also use endometrial biopsy to check for uterine infections, such as endometritis.
How reliable are tumor markers?
Tumor marker tests are not perfect. They are often not specific for cancer and may not be sensitive enough to pick up a cancer recurrence. The presence of tumor markers alone is not enough to diagnose cancer. You will probably need other tests to learn more about a possible cancer or recurrence.
How do you read a tumor marker results?

What does it mean when tumor markers go down?
Tumor marker tests are most often used to: Plan your treatment. If tumor marker levels go down, it usually means the treatment is working.
How is uterine cancer stage determined?
Stage I: Cancer that is confined to the uterus. Stage II: Cancer that has spread to the cervix. Stage III: Cancer that has spread to the vagina, ovaries, and/or lymph nodes. Stage IV: Cancer that has spread to the urinary bladder, rectum, or organs located far from the uterus, such as the lungs or bones.
What level of ca125 indicates cancer?
The range of 0 to 35 U/mL is considered within the normal guidelines. Levels over 35 U/mL may indicate the presence of cancer or other conditions. Not all patients with a high CA-125 result have cancer. For women with no ovarian cancer history, a high result usually leads to additional testing.

What is a liquid biopsy?
Liquid biopsy tests can often detect multiple cancer-associated biomarkers. For example, the Foundation One Liquid CDx test is approved for the detection of genetic mutations in 324 genes and two genomic signatures in any solid tumor type.
Where are genomic markers found?
Increasingly, however, genomic markers (such as tumor gene mutations, patterns of tumor gene expression, and nongenetic changes in tumor DNA) that are found in tumors themselves and in tumor fragments shed into bodily fluids are being used. Many different tumor markers have been characterized and are in clinical use.
What is a biomarker test?
Tests for these biomarkers are usually genetic tests that look for changes in genes that affect cancer growth. More information is available on the Biomarker Testing for Cancer Treatment page and in the Targeted Cancer Therapies fact sheet.
What is the treatment for uterine cancer?
Uterine cancer symptoms include bleeding between periods or after menopause. Uterine cancer treatment often includes a hysterectomy to remove the u terus (womb).
What are the symptoms of endometrial cancer?
Symptoms of endometrial cancer or uterine sarcoma include: Vaginal bleeding between periods in women before menopause. Vaginal bleeding or spotting in postmenopausal women, even a little amount. Lower abdominal pain or cramping in the pelvis, just below the belly.
What age do uterine cancers occur?
Most uterine cancers occur after age 50. Diet high in animal fat: A high-fat diet can increase the risk of several cancers, including uterine cancer. Fatty foods are also high in calories, which can lead to obesity. Extra weight is a uterine cancer risk factor.
What is CA 125 test?
Lab tests: CA-125 assay is a blood draw that measures CA-125, a protein. A certain amount of CA-125 can point to cancer in the body. Imaging tests: CT scans take a series of detailed pictures of the inside of the body. MRI scans use radio waves and a powerful magnet to create images.
Can uterine cancer cause bleeding?
Signs of uterine cancer can resemble those of many conditions. That’s especially true of other conditions affecting reproductive organs. If you notice unusual pain, leaking or bleeding, talk to your healthcare provider. An accurate diagnosis is important so you can get the right treatment.
Is endometrial cancer the same as uterine cancer?
But people often treat the terms “endometrial cancer” and “uterine cancer” the same. That’s because endometrial cancers are much more common than other cancers that arise in the uterus.
How to prepare for uterine cancer testing?
If your doctor schedules uterine cancer testing, it’s important to follow all preparation steps. These may include arranging for someone to drive home afterward. Be aware of any guidelines to follow once home, such as getting rest and monitoring for side effects.
What is the most common lab test for uterine cancer?
Doctors may also recommend blood tests to help diagnose or stage endometrial cancer, including: Advanced genomic testing is the most common lab test for uterine cancer. The analysis examines a tumor for DNA alterations that are driving the growth of cancer.
What is the most common type of cancer in the uterus?
Endometrial cancer is the more common type of cancer affecting the uterus. Cancer cells develop in the endometrium, the lining of the uterus. Uterine sarcom is both rare and difficult to treat because of its aggressive nature. It occurs when cancer cells develop in the muscles of the uterus or tissues that support it.
What test is used to determine if a sarcoma has spread beyond the uterus?
Transvaginal ultrasound. Other kinds of tests may be needed to determine whether uterine sarcoma has spread beyond the uterus. These include: Cystoscopy uses a lighted tube, or scope, to determine whether the cancer has reached the bladder.
What tests are done to detect endometrial cancer?
The main tests to detect endometrial cancer fall into two categories—ultrasound and endometrial tissue sampling .
Why do you need to drink water for a transvaginal ultrasound?
Preparation may include drinking water, because a full bladder helps create better images. For a transvaginal ultrasound, which provides a more detailed view of the uterus, the doctor inserts a probe through the vagina to capture images of the uterus.
What is the best way to find out if you have cancer in your rectum?
Proctoscopy, which also uses a lighted tube, helps determine whether the cancer has reached the rectum. Computed tomography (CT) scan is a specialized X-ray machine that takes pictures of multiple areas of the body. It may be helpful in determining whether the cancer has spread elsewhere in the body.
How is uterine cancer treated?
Uterine cancer is treated by 1 or a combination of treatments, including surgery, radiation therapy, and systemic treatments using medications.
What is the best treatment for uterine cancer?
Targeted therapy for uterine cancer is available in clinical trials and, in some instances, as part of standard-of-care treatment regimens. Targeted therapy for uterine cancer includes: 1 Anti-angiogenesis therapy. Anti-angiogenesis therapy is focused on stopping angiogenesis, which is the process of making new blood vessels. Because a tumor needs the nutrients delivered by blood vessels to grow and spread, the goal of anti-angiogenesis therapies is to “starve” the tumor. Bevacizumab (Avastin) is a type of anti-angiogenesis therapy used to treat uterine cancer. 2 Mammalian target of rapamycin (mTOR) inhibitors. In endometrial cancer, mutations in a pathway called mTOR are commonly found. People with advanced or recurrent uterine cancer may be treated with a drug that blocks this pathway, such as everolimus (Afinitor). Other drugs that target this pathway are being studied, such as ridaforolimus and temsirolimus (Torisel), a targeted therapy approved to treat a type of kidney cancer called renal cell carcinoma. 3 Targeted therapy to treat a rare type of uterine cancer. Uterine serous carcinoma is a rare but aggressive type of endometrial cancer. About 30% of these tumors express the HER2 gene. In a phase II clinical trial, researchers found that trastuzumab (Herceptin) combined with a combination of chemotherapy was effective in treating these kinds of tumors. Trastuzumab is a HER2 targeted therapy mostly used to treat HER2 -positive breast cancer.
What is the procedure to remove a tumor from the uterus called?
Surgery is the removal of the tumor and some surrounding healthy tissue, called a margin, during an operation. It is typically the first treatment used for uterine cancer. A surgical gynecologic oncologist is a doctor who specializes in treating gynecologic cancer using surgery.
What is standard of care for uterine cancer?
This section explains the types of treatments that are the standard of care for uterine cancer. “Standard of care” means the best treatments known. Clinical trials may also be an option for you, which is something you can discuss with your doctor.
How does cancer affect you?
Cancer and its treatment cause physical symptoms and side effects, as well as emotional and social effects. Managing all of these effects is called palliative care or supportive care. It is an important part of your care that is included along with treatments intended to slow, stop, or eliminate the cancer. Cancer treatment can also have financial side effects. You can bring financial concerns up with your multidisciplinary team, which may have social workers or financial counselors available to help.
When is chemo given for endometrial cancer?
When recommended for endometrial cancer, chemotherapy usually is given after surgery. Chemotherapy is also considered if the endometrial cancer returns after the person's initial treatment. A chemotherapy regimen, or schedule, usually consists of a specific number of cycles given over a set period of time.
Is it important to weigh the benefits of cancer treatment?
It’s important to weigh the benefits of treatment to possibly keep the cancer from returning with the risks of the treatment. The risks of treatment may include the short- and long-term side effects and a possible decrease in your quality of life. What you consider a decrease in quality of life is very personal.
