Can Ca125 Detect Breast Cancer

Women With Increased Risk*

CA-125 Test | Cancer Antigen | Blood test for Ovarian and other Cancers

This category includes woman with any of the following:

  • A first degree relative with ovarian cancer.
  • A personal history of breast cancer prior to age 40.
  • A personal history of breast cancer diagnosed prior to age 50, and one or more close relatives diagnosed with breast or ovarian cancer at any age.
  • Two or more close relatives diagnosed with breast cancer prior to age 50 or with ovarian cancer diagnosed at any age.
  • Ashkenazi Jewish heritage and a personal history of breast cancer prior to age 50.
  • Ashkenazi Jewish heritage and a first- or second-degree relative diagnosed with breast cancer prior to age 50 or with ovarian cancer at any age.

* These estimates are obtained from studies in which genetic testing information was not available. For individuals who meet the family history criteria but have tested negative for a genetic mutation known to increase susceptibility to the disease, the risk of developing ovarian cancer may be substantially lower. These women should consult a medical professional for screening recommendations.

Early Detection Of Hereditary Syndromes

At present, no randomized data support routine screening in the general population for ovarian cancer, and no professional society recommends using CA 125 for routine screening. However, several societies suggest using CA 125 for early detection in high-risk patients, such as those with a genetic predisposition for hereditary ovarian cancer syndromes.

Individuals with a deleterious mutation in the genes BRCA1 or BRCA2 are qualified as having hereditary breast and ovarian cancer syndrome . In these women, the lifetime risk of developing ovarian cancer ranges from 11% to as high as 62% in some series.

In patients with HBCOS who have not elected to undergo salpingo-oophorectomy as primary prevention, the NCCN recommends considering concurrent transvaginal ultrasonography and CA 125 measurements every 6 months starting at age 30 years or 5-10 years before the earliest age of first diagnosis of ovarian cancer in the family.

A National Institutes of Health consensus panel also recommends annual CA 125 measurements in addition to pelvic examinations and TVUS among women with HBCOS, who have an estimated lifetime risk of 40% of developing ovarian cancer.

Lastly, the NCCN also recognizes that concurrent CA 125 and TVUS may also be helpful in early detection in patients with hereditary nonpolyposis colorectal cancer or Lynch syndrome, at the clinicianâs discretion.

Patient preparation: No patient preparation is needed prior to the collection of the sample

Early Detection Saves Lives

Each year about 1400 women in Australia are diagnosed with ovarian cancer. The main risk factor for ovarian cancer is getting older. It is most commonly diagnosed in women who are over 50 years of age.

Ovarian cancer can be difficult to diagnose at an early stage, largely because symptoms can be vague and similar to those of other common illnesses.

Adjunct In The Discrimination Of Pelvic Masses

Elevations in CA 125 levels are used as an adjunct to aid in differentiation of malignant from benign pelvic masses detected with clinical examination or imaging. This is particularly useful in postmenopausal women, in whom confounding variables from benign and physiologic conditions are absent or infrequent. CA 125 can be used to calculate a risk of malignancy index , which is used to form the basis of algorithms in the management of pelvic masses in the United Kingdom.

Women With Inherited Risk

  • While it is not clear that ovarian cancer screening will result in a decrease in the number of deaths in women at inherited risk, those who have mutations in ovarian cancer susceptibility genes should undergo ovarian cancer screening using a combination of transvaginal ultrasound and CA-125 testing. For women with mutations in BRCA1 or the mismatch repair genes, MLH1, MSH2, and MSH6, this screening should generally begin between ages 30 and 35. For women with mutations in BRCA2, ovarian cancer screening should be initiated between ages 35 and 40.

Given the limitations of ovarian cancer screening, including the substantial risks of both false positive and false negative results, risk-reducing salpingo-oophorectomy should be considered upon conclusion of childbearing by women with documented inherited predispositions.

What Do The Results Mean

If you are being treated for ovarian cancer, you may be tested several times throughout your treatment. If testing shows your CA-125 levels have gone down, it usually means the cancer is responding to treatment. If your levels go up or stay the same, it may mean the cancer is not responding to treatment.

If you have finished your treatment for ovarian cancer, high CA-125 levels may mean your cancer has come back.

If you are not being treated for ovarian cancer and your results show high CA-125 levels, it can be a sign of cancer. But it may also be a sign of a noncancerous condition, such as:

  • Endometriosis, a condition in which tissue that normally grows inside the uterus also grows outside the uterus. It can be very painful. It may also make it harder to get pregnant.
  • Pregnancy
  • Menstruation, at certain times during your cycle

If you are not being treated for ovarian cancer, and your results show high CA-125 levels, your health care provider will probably order more tests to help make a diagnosis. Talk to your health care provider if you have questions about your results.

If your health care provider thinks you may have ovarian cancer, he or she may refer you to a gynecologic oncologist, a doctor who specializes in treating cancers of the female reproductive system.

What Are The Ovarian Cancer Symptoms I Need To Look Out For

Symptoms that may indicate ovarian cancer are vague. It may include one or more of the following:

  • abdominal bloating
  • difficulty eating or feeling full quickly
  • frequent or urgent urination
  • back, abdominal or pelvic pain
  • constipation
  • indigestion
  • pain during sexual intercourse.

These symptoms are often related to more common, less serious health problems and most women will have these symptoms at some time. However, if you notice any unusual changes or these symptoms persist, visit your doctor.

Remember, if you have any concerns or questions, please contact your doctor.

What Is The Roca Test

The ROCA Test is a test that uses the change in CA-125 over time, combined with other factors , to predict risk of having ovarian cancer. The test must be ordered by a doctor, but can be purchased directly for $295. Though the ROCA Test is being marketed to women and encouraging them to ask for it as part of their annual check-up, there is no evidence that this test prevents women from dying from ovarian cancer.

Diagnostic Utility Of Serum Tumor Markers In Endometrial Carcinoma

CA 125 Cancer Antigen 125

The cut offs provided by ROC curve analysis were used to distinguish endometrial cancer patients and AUB cases. The cutoff of 27.55 U/mL for CA 15-3 showed sensitivity, specificity, PPV and NPV of 44.74%, 82.5%, 70.8% and 61.1% respectively. A cut off of 17.8 U/mL for CA 125 showed sensitivity, specificity, PPV and NPV of 52.63%, 80%, 71.4% and 64%. Even though CEA and prolactin have high specificity, their low sensitivity prevents the use of these two markers to differentiate EC and AUB. When AUC was compared for diagnostic significance, CA125 had highest AUC of 0.66.

Kurihara et al. suggested a CA 125 cut-off of 20 U/ml for predicting myometrial infiltration with sensitivity of 69.0%, specificity of 74.1%, positive predictive value of 58.8% and negative predictive value of 81.6%. They have also found that elevated CA 125 levels is usually associated with advanced stage and poorer clinical outcome. A study by Kanat-Pektas et al. showed similar diagnostic power for CA 125. The sensitivity, specificity, PPV and NPV for CA 125 in their study was 42.2%, 87.4%, 77% and 60.2% respectively. Among the tumour markers analysed, CA-125 has the comparatively better sensitivity, specificity and high AUC with the cut-off of 17.8 U/mL. Therefore CA-125 can differentiate EC in AUB patients from uterine bleeding due to other causes.

Is Ca 125 Testing Useful As An Ovarian Cancer Screening Test

Although CA 125 is a useful test in monitoring women who are being treated for ovarian cancer, a single CA 125 test is not considered to be a useful screening test for cancer. Some women with ovarian cancer never have elevated CA 125 levels, while most women who do have elevated CA 125 levels do not have cancer. In fact, because the results of CA 125 testing can be elevated in so many noncancerous conditions , only about 3% of women with elevated CA 125 levels have ovarian cancer.

What About The Blood Test Ca125

The blood test CA125 can be used to help diagnose or exclude ovarian cancer. CA125 is a protein found in the blood and can be produced by ovarian cancer cells.

However, there are other causes for raised CA125 levels such as menstruation, endometriosis or ovarian cysts.

Half of all women with early stage ovarian cancer do not have elevated CA125 levels. The CA125 test is more reliable in postmenopausal women. It is for these reasons CA125 is not recommended as a screening test for women with no symptoms.

For those women with symptoms, the CA125 test alone cannot be used to investigate the symptoms. Transvaginal ultrasound should be used in conjunction with the CA125 test to diagnose ovarian cancer.

Monitoring Response To Therapy

Which is the most widely used tumor markers for early ...

The Gynecologic Cancer Intergroup defines a response to treatment as a reduction of 50% or more in pretreatment CA 125 levels maintained for at least 28 days. The pretreatment value must be at least twice the upper limit of the reference range and taken 2 weeks prior to treatment. Subsequent samples are taken at weeks 2 and 4 of treatment and at intervals of 2-3 weeks thereafter. However, tumor recurrence may occur in the setting of normal CA 125 levels, and serum measurements do not replace imaging and physical examination of the patient.

A study by Potenza et al indicated that in patients with epithelial ovarian cancer, combined analysis of CA 125 and human epididymis protein 4 is an effective indicator of success in chemotherapy. Negativization of CA 125 and HE4 following the third cycle of chemotherapy correlated with long progression-free survival , as did âbiomarker serum levels lower than the mean value in the affected population at the time of diagnosisâ .

Can A Full Blood Count Test Show Cancer

Or do you need a more detailed blood test? Just wondering as I’ve been having unexplained fatigue and chest pains and would love to be able to mentally rule out cancer!

There’s quite a detailed explanation of full blood count results here. It can give results that could indicate cancer, but it wouldn’t rule out every cancer.Why do you suspect cancer, out of interest? I’m sure there are plenty of much more likely possibilities, anaemia, for example. I hope that you get some reassurance soon, and that they can identify the cause of your symptoms quickly and fix it

Do you have anxiety op? I’m not trying to diagnose you but those symptoms could also be attributed to anxiety.

No I don’t have anxiety

Thank you for link. Not really sure what’s wrong with me but my body is def not right – I’m exhausted, getting random awful chest pains occasionally, also have a very bloated tummy and can’t loose weight. I’ve had my thyroid checked etc. I’m low in vitamin d and iron and have been through a very stressful time lately not looking after myself. I just wanted to be able to cross of cancer as a possibility as a family member died from ovarian cancer recently. The drs never tell you what you don’t have! I find it really useful to know what has been ruled out.

Thank you. I’ll have to go back to GP and say I’m still fatigued and worried about the bloating etc.

Is There Anything Else I Should Know

Laboratories may use different methods to test for CA 15-3, so results can vary from lab to lab. If you are having a series of CA 15-3 tests done, it is advised that you have the tests done by the same method, typically by the same laboratory, so that the results can be compared and interpreted correctly. You may wish to discuss this issue with your healthcare practitioner.

Levels of CA 15-3 are not usually measured immediately after breast cancer treatment begins. There have been instances of transient increases and decreases in CA 15-3 that do not correlate with the persons progress. Usually, the healthcare practitioner will wait a few weeks after starting treatment to begin monitoring CA 15-3 levels.

What Are Tumor Markers Used For

Tumor markers are most often used to track how a patient’s cancer responds to treatment. If the level is going down, the treatment is working. If it goes up, the cancer may be growing. There are health issues that can cause markers to be elevated that are not cancer. Because of this, you must think about the tumor marker levels along with the results of radiology scans , the patients symptoms, and the healthcare providers exam.

In some cancers, markers are used to watch for recurrence . This is not useful in all cancer types. In breast cancer, research has found that watching tumor markers after treatment does not help people live longer. For that reason, they are not recommended.

Tumor markers can also be used along with other tests to help find cancer in a patient who has symptoms that are suspicious for cancer. Some markers can help healthcare providers predict how the patient will do and to pick a treatment plan.

What Is A Ca

This test measures the amount of a protein called CA-125 in the blood. CA-125 levels are high in many women with ovarian cancer. The ovaries are a pair of female reproductive glands that store ova and make female hormones. Ovarian cancer happens when there is uncontrolled cell growth in a woman’s ovary. Ovarian cancer is the fifth most common cause of cancer death in women in the U.S.

Because high CA-125 levels can be a sign of other conditions besides ovarian cancer, this test is not used to screen women at low risk for the disease. A CA-125 blood test is most often done on women already diagnosed with ovarian cancer. It can help find out if cancer treatment is working, or if your cancer has come back after you have finished treatment.

Other names: cancer antigen 125, glycoprotein antigen, ovarian cancer antigen, CA-125 tumor marker

Does Every Cancer Type Have A Tumor Marker

There is not a known tumor marker for all types of cancer. Also, tumor markers are not raised in all cases of the cancers they are used for, so they are not helpful for all patients. For example, carcinoembryonic antigen is a tumor marker used in colon cancer, yet only 70-80% of colon cancers make CEA. This means 20-30% of people with colon cancer will not have a raised CEA level. Only 25% of early stage colon cancers have a raised CEA. Because of this, CEA cannot always help find colon cancer in its early stages, when cure rates are best.

The bottom line is, tumor markers can be very helpful in watching a person’s response to treatment and, in some cases, watching for the cancer to return. However, they need to be used along with your healthcare providers exam, any symptoms you are having, and radiology studies .

Women With Increased Risk

Current and Prospective of Breast Cancer Biomarkers ...
  • There is no clear evidence to suggest that ovarian cancer screening with currently available methods will result in a decrease in the number of deaths from ovarian cancer. If, after careful consideration of risks and benefits, ovarian cancer screening with serum markers such as CA-125 and/or transvaginal ultrasound is to be pursued, it is recommended that such screening be done within the framework of research studies to evaluate the efficacy of this approach.

Genetic counseling may also be helpful for women in this group to better clarify the risk of ovarian and related cancers.
