Trucheck Breast – Annual Breast Cancer Screening Test

Early detection of breast cancer is vital for successful treatment and cure. Late detection invariably leads to intensive and toxic treatments, high treatment costs and treatment failure. Trucheck™ – Breast has been described as a game changer and is a revolutionary early breast cancer screening test, based on a simple blood draw, for early detection of Breast Cancer even before it is visible on an X-ray. Trucheck Breast is now available in the UK

Being a non-invasive blood-based test, Trucheck™ can minimize the need to visit a healthcare centre – since the blood sample can also be collected from the privacy and comfort of your home.

What are the Advantages of Trucheck™ Breast Screening Test

Advantages to the individuals:

  1. Wait times for appointments are reduced
  2. Minimized risk of COVID exposure
  3. May be assimilated into annual health check-up
  4. No risk of radiation or those associated with invasive procedures

Advantages to the system:

  1. Reduces risk of COVID transmission and exposure of staff
  2. Reductions in avoidable / non-critical appointments
  3. Minimizes procedures that may be retrospectively deemed unnecessary
  4. Supports decision making in conjunction with existing tests / methods

Why should I consider Trucheck™ Breast?

Circulating Tumor Cells (CTCs) and their clusters are present in the blood of almost all cancer patients and are undetectable even in seemingly healthy individuals.
Trucheck™ technology to detect and characterise CTCs has been proven through extensive clinical validations involving more than 40,000 participants.The test is a paradigm shift in cancer screening, as it does not involve radiation or invasive procedures. The test is performed at our world-class laboratory, which meets and exceeds all national and international standards.

Trucheck™ Breast is Accurate

The development of Trucheck™ – Breast included extensive Analytical and Clinical validation studies to establish its Accuracy and Reliability.
Trucheck™ – Breast has overall accuracy > 90%.

Recently published research has shown it is more effective in identifying breast cancer than breast x-rays (mammograms) with 5% higher detection rates of 92% over all and can detect early cancers before they are visible on X-ray.

Advantages of Trucheck™ Breast Over Conventional Screening

  • Minimize Procedures – Minimizes procedures that may be retrospectively deemed unnecessary.
  • Radiation Free – No risk of radiation or those associated with invasive procedures.
  • Save Time – Reductions in avoidable / non-critical appointments.
  • Early detection saves lives – late stage survival 22% versus 90% with early stage detection.

Breast Cancer Early Diagnosis and Survival

Breast Cancer Early Diagnosis and Survival

Cancer – A Global Perspective

Every year about 18 million women and men are diagnosed with various cancers including carcinomas, sarcomas, neuroendocrine tumors, melanomas. These cancers are also associated with about 9 million deaths. This translates into roughly 34 cancer cases being detected and 18 cancer-related deaths every minute. Annually, these cancers contribute to:

  • ~4.1 million newly diagnosed cases and 1.8 million deaths in Europe (including the UK).
  • ~2.1 million newly diagnosed cases and 550,000 deaths in the US.
  • ~1.2 million newly diagnosed cases and 760,000 deaths in India.

Due to changes in lifestyle as well as other risk factors, these numbers likely to increase in the future.

FAQs

1. Does Trucheck detect ‘existence of cancer’ or ‘possibility of cancer’? It detects ‘existence of cancer’.

2. Does Trucheck replace conventional cancer screening like mammography?  Trucheck is not intended to be and should not be considered as a replacement for any Standard of Care screening tests.

3. Does a ‘negative’ Trucheck result mean that I am ‘totally’ cancer free? Within the limits of error, a ‘negative’ result is a reasonable indication of undetectable cancer of the type covered by the test. For other cancers not covered by the test, no inference should be drawn from a ‘negative’ result.

4. Does a ‘negative’ Trucheck result mean that I am free from cancer forever? A ‘negative’ results means that at the time of the test there were no detectable cancer cells circulating in the blood.

5. How frequently should Trucheck™ be repeated? As Trucheck™ is a non-invasive blood test, there is no disadvantage in frequent testing. However, we advise that Trucheck™ should be performed every 12 months in case of every negative result.

7. Is Trucheck recommended for a person suspected to have / has symptoms of cancer? No, such individuals should seek expert medical advice without delay.

8. Can Trucheck be used to monitor recurrence after cancer treatment? No.

This table compares the clinical performance of the Trucheck test with conventional cancer screening tests for different cancers. The results are based on a blinded prospective study involving 15,441 cancers, 700 benign cases and 13,919 asymptomatic individuals.

What does the DETECTION RATE mean?

The detection rate or sensitivity is the ability to correctly identify those who DO have cancer in a group of people with and without cancer. For example, in a group of women with and without breast cancer, Trucheck Breast will correctly identify 88.2% of those who DO have breast cancer. This is better than a mammogram.

What is SPECIFICITY?

This is the ability to correctly identify those that DO NOT have cancer in a group of people with and without cancer. For example, in a group of women with and without breast cancer, Trucheck Breast will correctly identify 99.9% of those cases who DO NOT have breast cancer. This is better than a mammogram.

What is the POSITIVE PREDICTIVE VALUE (PPV)?

This is the likelihood that if the test is positive that the individual WILL actually have cancer. For example, when the Trucheck Breast test shows a high probability of a woman having breast cancer, then there is a 99.9% chance that they WILL actually have breast cancer. This is better than a mammogram.

What is the NEGATIVE PREDICTIVE VALUE (NPV)?

This is the likelihood that if the result is negative that the individual WILL NOT have cancer. For example, when the Trucheck Breast test shows a low probability of a woman having breast cancer, then there is a 99.9% chance that they WILL NOT have breast cancer. This is better than a mammogram.
