Figure S2 from The Origin of Highly Elevated Cell-Free DNA in Healthy Individuals and Patients with Pancreatic, Colorectal, Lung, or Ovarian Cancer

Supplemental Figure 2. The concentration of plasma cfDNA in previous described patients with cancer according to stage. (A) The concentration of cfDNA in patients of all cancer types (9). The concentration of cfDNA in patients with Stage III cancers was significantly higher than that of patients with Stage I cancers (p < 0.01). (B) The concentration of cfDNA in individual cancer types. Stage was classified according to AJCC 7th edition. The concentration of cfDNA in patients with Stage III breast cancer was significantly higher than that of patients with Stage I breast cancer (p < 0.05). For both panels, data were derived from the previously published CancerSEEK study (9).
