According to the study, a novel Breast Cancer Recurrence Blood Test can identify high-risk patients’ chances of developing breast cancer again months or even years before they do.
After treating early-stage breast cancer. A team from The Institute of Cancer Research in London employed an ultra-sensitive liquid biopsy to find any remaining cancer DNA in the body.
Blood samples from the ChemoNEAR sample collection research were examining for circulating tumor DNA (ctDNA). Which is releasing into the circulation with cancer cells. The results were presenting at the American Society of Clinical Oncology (ASCO) annual meeting in Chicago on Sunday, June 2.
According to Breast Cancer UK, 2.26 million women received a diagnosis of breast cancer in 2020, and the disease claimed 685,000 lives. Breast cancer is the most prevalent type of the disease globally.
The trial, which involved 78 patients with various forms of early breast cancer recurrence blood tests, was carring out by a group of researchers from the Institute of Cancer Research (ICR) in London.
What is Breast Cancer Recurrence Blood Test?
The ICR experts anticipate the findings may assist in identifying patients. Who are most likely to relapse, opening the door to a new approach. To treating recurrent breast cancer in which therapy can begin much sooner rather than waiting for incurable, advanced illness to emerge and manifest on a scan.
The majority of tests employ a method known as whole exome sequencing (WES). Which concentrates on the exons—the protein-coding sections of genes—that are directly linked to illnesses. Even though prior research has demonstrated that ctDNA blood tests can detect relapse far before it can be visible on a scan.
What is the purpose of the study?
The goal of the clinical trial TRAK-ER is to determine whether a novel blood test may be using to identify individuals. Who are more likely to experience a recurrence of their cancer. This method looks for cancer DNA in the blood. Which can occasionally be found months or years before secondary cancer is seen on a scan.
Additionally, the researchers are examining whether palbociclib and fulvestrant treatment is superior to conventional hormone therapies in preventing cancer recurrence in patients with oestrogen receptor positive and HER2 negative breast cancer (ER+ HER2-breast cancer).
Screening and Testing
Early detection of breast cancer and determining the best course of treatment for those who are diagnosing with the disease depend on medical testing. A particular set of tests will be suggested as your doctors based on your particular circumstances. As part of screening, diagnosis, treatment, or follow-up care and monitoring, you may undergo imaging tests, physical examinations, a biopsy, or other testing.
Types
- Screening tests: To detect breast cancer early, before any symptoms appear, routine screening tests are performed, such as annual mammograms. Early detection of breast cancer may make treatment simpler. When to begin screening for breast cancer is a decision that you and your physician may make.
- Diagnostic tests: When your doctor believes. You may have breast cancer based on your symptoms or the findings of a screening test. Diagnostic tests (like a breast biopsy) are performing. To find out if breast cancer is present and, if it is. Whether it has spreading outside the breast, diagnostic tests are utilizing.
- Tests for prognosis and prediction: Prognostic tests tell us how likely it is that breast cancer will develop, spread, or return following therapy. Predictive tests aid in forecasting the potential impact of a certain treatment on the course of the illness. Certain tests are using to help determine whether specific treatments might lower the chance of breast cancer returning after treatment because they are both prognostic and predictive.
- Monitoring tests: Monitoring tests are performing to assess the effectiveness of your treatments both during and after therapy. After treatment, monitoring tests can also be conducting to check for any recurrence of the cancer.
What makes this study significant?
This study examines the validity of a single test, the detection of ctDNA. As a predictor of relapse in patients with early-stage breast cancer. A diagnostic that anticipates recurrence before it is currently clinically evident could enhance survival results by enabling earlier or possibly different therapy.
What is the average time for breast cancer recurrence?
The majority of local Breast Cancer Recurrence Blood Test happen five years after a lumpectomy. Afterward, you can receive radiation therapy to reduce your risk. With this combined treatment, your chances of developing breast cancer again within ten years are between three and fifteen percent. To further lower your risk, your provider might suggest extra therapies based on genetic testing.
Those who have had mastectomy have varying recurrence rates:
- If medical professionals failed to detect cancer in your axillary lymph nodes. After your initial operation, you have a 6% chance of developing cancer again within five years.
- If you have malignant lymph nodes in your axilla, your chances of getting cancer again are 25%. If you have radiation therapy following a mastectomy, this risk decreases to 6%.
