The evolving role of ctDNA in colorectal cancer: guidance of adjuvant therapy or surveillance strategies?

Key Points

• ctDNA may effectively guide adjuvant therapy decisions in patients with colorectal cancer, especially postoperative.
• In a recent observational analysis, ctDNA detection showed significant clinical utility for treatment monitoring and relapse identification.
• Monitoring ctDNA levels can enhance current surveillance strategies, allowing for timely interventions and personalized care.
• Findings suggest ctDNA testing could lead to improved outcomes, though further validation is required across diverse populations.
