Circulating Tumor DNA: Transforming Oncology Clinical Trials
Use of circulating tumor DNA (ctDNA) – small fragments of DNA that are released into the bloodstream by cancer cells – as a diagnostic tool represents a significant shift toward more precise, personalized cancer care, enhancing both trial efficiency and patient experience. Unlike traditional tissue biopsies, which sample a single tumor site, ctDNA offers a real-time, comprehensive view of the genetic mutations present in the tumor throughout the body. By offering faster, more detailed insight...
