What is the new DNA blood test developed by the Institute of Cancer Research?

The Institute of Cancer Research developed a simple DNA blood test that analyzes circulating tumor DNA (ctDNA) to predict a breast cancer patient's response to treatment.

How does the ctDNA blood test help breast cancer patients?

The ctDNA blood test helps by predicting treatment effectiveness early, allowing doctors to offer the most suitable therapies and avoid those that may not work, thus improving patient outcomes.

Can this DNA test be used for early-stage breast cancer?

While the research focused on advanced breast cancer, experts believe these tests could also be effective for early-stage breast cancers, potentially speeding up treatment decisions.

New DNA Test Predicts Breast Cancer Treatment Success

A revolutionary DNA blood test has been developed by researchers, offering the potential to transform breast cancer treatment. This simple liquid biopsy analyzes circulating tumor DNA (ctDNA) released into the bloodstream by cancer cells, providing an early prediction of a patient's response to therapy. The test, trialled on 167 patients with advanced breast cancer, showed a strong association between low ctDNA levels and positive treatment outcomes.

This innovative approach means that patients could be offered the most effective treatment from the outset, avoiding therapies unlikely to work and potentially preventing cancer growth. For instance, individuals could receive alternative targeted therapies, drug combinations, or be enrolled in clinical trials based on these early blood test results. Trials are currently underway to confirm if adapting treatment based on these findings improves patient outcomes.
