Sasha Watson Highlights ctDNA’s Potential for Early Colon Cancer Detection and Personalized Treatment Strategies
Sasha Watson, PharmD, BCOP, presented insights into the developing role of circulating tumor DNA (ctDNA) in colon cancer management. Her discussion focused on ctDNA’s potential contributions to precision oncology through improved early detection of the disease, better decision-making regarding adjuvant therapy, and more effective monitoring of disease recurrence and the emergence of treatment resistance. Watson explained that ctDNA analysis could offer a new approach to detecting colon cancer earlier. In addition, ctDNA may also provide clinicians with data to individualize adjuvant therapy plans based on a patient’s specific tumor characteristics and treatment response. Finally, monitoring ctDNA levels could allow for the earlier detection of disease recurrence and the identification of mechanisms driving resistance to treatment, she stated.
