Ultra-sensitive detection of circulating tumor DNA identifies patients in high risk of recurrence in early stages melanoma

Background null Up to 70% of patients with resected high-risk melanoma develop disease recurrence within 5 years. Adjuvant immunotherapy or targeted therapy can reduce the recurrence rate below approximately 60%; however, it is at the cost of possible toxicity including long-term side effects. We hypothesize that detection of plasma-derived circulating tumor DNA (ctDNA) from patients with resected melanoma can identify patients in high-risk of...
