Fig. 2: ctDNA positivity could potentially serve as a prognostic marker and guide ACT treatment.

a Kaplan–Meier curve of recurrence-free survival (RFS) in patients stratified by postsurgical ctDNA status. p-value was calculated by the log-rank test. b Kaplan–Meier curve of RFS in patients stratified by post-ACT ctDNA status. p-value was calculated by the log-rank test. c Kaplan–Meier curve of RFS in stage II–III patients stratified by both ACT treatment and postsurgical ctDNA status. p-value was calculated by the log-rank test for each comparison without adjustments. d Kaplan–Meier curve of RFS in patients stratified by longitudinal ctDNA status. p-value was calculated by the log-rank test.
