Fig. 1From: Different next-generation sequencing pipelines based detection of tumor DNA in cerebrospinal fluid of lung adenocarcinoma cancer patients with leptomeningeal metastasesDetection rates and mutation allele fractions of different kinds of samples a. The difference of detection rates among 4 kinds of samples. Y- axis means No. of sample with mutations divided by No. of samples tested. p1, plasma vs. CSF cfDNA; p2, plasma vs. CSF cells; p3, plasma vs. FFPE. b. The maximum mutation allele fractions of the different kinds of samples in patients from which 3 or 4 kinds of sample were collectedBack to article page
