ctDNA was a strong predictor of recurrence in rectal cancer, including in NOM settings. In NOM patients, ctDNA detected local recurrences, highlighting its potential to guide post-NAT surveillance and treatment.
During surveillance, ctDNA re-emergence precedes clinical or radiographic relapse in every case. These findings support the consideration of ctDNA as a dynamic, treatment-responsive biomarker warranting prospective validation for risk-adapted surveillance and adjuvant therapy in ASCC.
We found that early ctDNA dynamics after only 3-4 weeks of ICI initiation in patients with advanced-stage melanoma appears to be a candidate strategy to predict overall treatment response, risk of progression, and long-term survival. Larger prospective studies are warranted to validate the utility of early ctDNA changes in treatment monitoring.

MRD testing in early-stage breast cancer theoretically confers a significant clinical benefit with adjuvant therapy and during patient surveillance. However, there are concerns with the potential for aggressive or prolonged treatment, not to mention the specific approach to managing patients who are ctDNA positive but remain asymptomatic.
