ctDNA-Guided Adjuvant Therapy in Stage III Colon Cancer: DYNAMIC-III Validates Prognosis but Questions Intensification

The randomized phase 2/3 DYNAMIC-III trial shows that postoperative circulating tumor DNA (ctDNA) strongly stratifies recurrence risk in stage III colon cancer. ctDNA-guided de-escalation reduced oxaliplatin exposure and hospitalizations with outcomes close to standard care; escalation for ctDNA-positive disease did not improve recurrence-free survival.

ctDNA-Guided Adjuvant Therapy in Stage III Colon Cancer: Prognostic Validation but No Benefit from Chemotherapy Intensification — Key Findings from the DYNAMIC-III Randomized Phase 2/3 Trial

The DYNAMIC-III trial validates circulating tumor DNA (ctDNA) as a strong prognostic marker in stage III colon cancer. ctDNA-guided de-escalation reduced oxaliplatin exposure and hospitalizations with near-standard outcomes, but escalation for ctDNA-positive patients failed to improve recurrence-free survival.
