Fig. 3: Mutation tracking at serial time points predict patient survival.

Kaplan–Meier curves of disease-free survival (a) and overall survival (b) associated with detection of ctDNA in any post-operative plasma samples in patients with gastric cancer resected. Numbers of patients and log-rank p value are shown. c Detailed survival data of patients are shown, with gray bars indicating disease-free survival and orange bars indicating survival after recurrence. ctDNA+: ctDNA was detected; ctDNA−: ctDNA was not detected.
