Fig. 2From: Circulating free plasma tumor DNA in patients with advanced gastric cancer receiving systemic chemotherapyKaplan-Meier curve for the tDNA collected at the second collection time point and DFS (left curve) and OS (right curve). Group 1 (in red) represents patients with tDNA levels greater than or equal to the 75th percentile, while Group 2 (in blue) represents patients with levels below the 25th percentile. A statistically significant correlation was observed between high levels of tDNA collected at the second collection time point and lower DFS (p = 0.0228) but not between high levels of tDNA and OS (p = 0.2563)Back to article page
