Circulating Tumor DNA (ctDNA) Testing: A Game Changer in Breast Cancer Management

In an insightful interview, Dr. Barry Rosen, a seasoned breast surgical oncologist, sheds light on the revolutionary impact of circulating tumor DNA (ctDNA) testing in breast cancer management. This article highlights three key aspects of ctDNA testing discussed by Dr. Rosen, offering valuable insights for breast cancer survivors and those undergoing treatment.

ctDNA’s Role in Detecting Cancer Recurrence

One of the most significant applications of ctDNA testing lies in its ability to detect cancer recurrence earlier than conventional methods. Dr. Rosen emphasizes that ctDNA testing can identify cancer recurrences up to 12-18 months sooner than traditional symptom-based approaches. This early detection is crucial, as about 30% of breast cancer patients experience recurrence. The test works by identifying unique cancer DNA in the bloodstream, providing a dynamic snapshot of the cancer’s presence or absence at a microscopic level.

Personalized Treatment Monitoring with ctDNA

Dr. Rosen highlights that ctDNA testing is not just about detecting cancer’s return; it’s a powerful tool for personalized treatment monitoring. For patients undergoing chemotherapy, ctDNA levels can indicate how effectively the treatment is eliminating cancer cells. This personalized approach allows oncologists to tailor treatments based on individual responses, potentially reducing unnecessary chemotherapy for some patients and intensifying it for others whose ctDNA levels remain high post-treatment.

The Power of Informed Decision Making

The advent of ctDNA testing empowers patients with concrete information about their cancer status. Dr. Rosen points out that while false positives are extremely rare, the presence of ctDNA after treatment completion suggests a high likelihood of recurrence. This information enables patients and doctors to make informed decisions about further interventions, like clinical trials, much earlier than waiting for macroscopic signs of cancer through imaging tests.
