Figure 6 Survival outcomes according to preoperative and postoperative circulating tumor DNA status after resection. A and B: Recurrence-free survival (A) and overall survival (B) curves comparing patients with detectable vs undetectable preoperative circulating tumor DNA levels among those who underwent resection after neoadjuvant chemotherapy (n = 23); C and D: Recurrence-free survival (C) and overall survival (D) curves comparing patients with detectable vs undetectable postoperative circulating tumor DNA levels in the combined cohort of upfront resection and post-chemotherapy resection groups (n = 32). ctDNA: Circulating tumor DNA.
