Fig. 5From: Detection of genes mutations in cerebrospinal fluid circulating tumor DNA from neoplastic meningitis patients using next generation sequencingThe association of CSF ctDNA concentration with the Karnofsky performance status (KPS) scores, the number of gene mutations and the presence of CSF tumor cells. (A) CSF ctDNA concentration vs. KPS (r = − 0.038, P = 0.768). (B) CSF ctDNA concentration vs. the number of gene mutations (r = − 0.195, P = 0.129). (C) The number of gene mutations vs. KPS scores (r = 0.192, P = 0.135). (D) CSF ctDNA concentration vs. the presence of detectable circulating tumor cells in the CSF (Z = -2.883, P = 0.004)Back to article page
