WebApr 6, 2024 · Citation 16 This suggests the presence of detectable ctDNA in such patients may represent the existence of occult micro metastatic disease at the time of surgery. ctDNA can also be used in the surveillance of radically treated patients to detect minimal residual disease (MRD), i.e., molecular evidence of cancer soon after curative treatment. WebApr 26, 2024 · One patient with consistent ctDNA-positivity had a recurrence on day 610, suggesting that he had MRD for a relatively long period. Further discussion of their study suggested that patients with ctDNA-positivity were thought to be at high risk for recurrence and metastasis (log-rank, p < 0.001) by Kaplan–Meier analysis.
