ROCA FAQs

What is the ROCA® Test?

1. What is the ROCA Test?

The ROCA Test is a simple blood test that detects the likelihood of a woman having ovarian cancer.

The ROCA Test uses a woman’s age, menopausal status, risk status and serial blood measurements of CA-125 to produce a score that indicates her chances of having ovarian cancer. It has been rigorously tested in trials and proven to more accurately detect ovarian cancer earlier than other tests1.

2. How is the ROCA Test different from the CA-125 blood test?

The ROCA Test is the only test for the earlier detection of ovarian cancer that has been evaluated in major clinical trials and shown to be significantly more accurate than the CA-125 blood test. The ROCA Test uses your CA-125 measurements, establishing your baseline levels of CA-125 to reveal an individualized profile of change over time rather than relying on a single CA-125 fixed cutoff value.

Eligibility and Risk for Ovarian Cancer

1. How do I know if I am eligible for the ROCA Test?

You may be eligible for the ROCA Test if you are between 35 and 85 years with a known mutation in the BRCA1 or BRCA2 genes.

You should talk with your doctor about whether the test is right for you.

2. How do I know if I have a family history of ovarian and/or breast cancer?

If several members of your family have had ovarian and/or breast cancer (including male breast cancer), you may be classed as having a family history of these cancers. However, your history will also depend on your ethnicity and other factors. To understand your risk of ovarian cancer you should make an appointment to speak with your clinician who will review your medical history to determine if you have a family history that may increase your risk of ovarian cancer and if appropriate undertake a BRCA test.

4. Can I take the ROCA Test if I have had ovarian cancer?

No, patients who have had ovarian cancer do not meet the criteria for the ROCA Test.

5. Can I take the ROCA Test if I am pregnant?

No, patients who are pregnant are not eligible to take the ROCA test. You may resume testing 6 weeks after the end of your pregnancy.

6. Can I take the ROCA Test while receiving hormone replacement therapy (HRT)?

Yes, but it is recommended to wait until 12 months after starting HRT for menopausal symptoms before starting the ROCA Test.

7. If I have had my ovaries removed (bilateral oophorectomy), but I still have my fallopian tubes, should I take the ROCA Test?

Women who have had both of their ovaries removed, but still have their fallopian tubes, do not meet the criteria for the ROCA Test unless they are aged 35-85 and are at high risk for ovarian cancer.

8. I am at high risk for ovarian cancer. Why do I need to be between 35 and 85 years old to take the test?

The ROCA Test was evaluated in a 4 year study in this population of women considered to be at high risk of ovarian cancer. Those who were not between 35-85, were not included in the study.

9. What is the definition of postmenopausal?

A woman is considered to be postmenopausal when she has not had her period for 12 months or after 12 months of starting HRT for menopausal symptoms.

Taking the ROCA Test

1. How often should I have the ROCA Test?

How frequently you should have the ROCA Test will be determined by your clinician based on your risk factors for ovarian cancer as well as your test results:

It is recommended that you have a ROCA test 3 times a year.

If your results are not Normal, your clinician may recommend a repeat ROCA Test within the next six weeks. You may also be referred for a transvaginal ultrasound (TVUS) scan of your ovaries or other clinical assessment determined by your clinician.

2. If I miss a ROCA Test, can I start again and continue testing?

You can always start taking the ROCA Test again, even if you have stopped for a period of time. Discuss this with your clinician

ROCA Results

1. What does my ROCA Test result tell me?

Your ROCA Test result provides you with your own personal risk assessment of having ovarian cancer. Your result may include:

  • A numerical score (e.g., 1 in 5000)
  • A categorisation (Normal, Intermediate or Elevated)

If your ROCA Test result is outside of the Normal range (Intermediate or Elevated) at any time during surveillanceit does not mean that you definitely have ovarian cancer. Your clinician may ask you to take a repeat ROCA Test within the next six weeks, refer you for a transvaginal ultrasound (TVUS) scan of your ovaries, or suggest other possible clinical assessments.

2. If my ROCA Test result is Normal, why do I need to take the test routinely?

The ROCA Test works by tracking your baseline CA125 level and accurately assessing change. Each time you have the test, all previous CA125 test results are used. Also, ovarian cancer can develop rapidly so regular testing is recommended.

3. How accurate is The ROCA Test?

The ROCA Test has been evaluated in a trial called UK Familial Ovarian Cancer Screening Study (UKFOCSS), in which over 4,300 women with a mutation in the BRCA1 or BRCA2 gene or a family history of ovarian and/or breast cancer. Women were tested every 4 months. This study showed that surveillance identified more early stage cancers than no screening.
