    Abstract: The concordance of mutation patterns between cell-free DNA (cfDNA) and tumor DNA varies in colorectal cancers (CRCs). Next-generation sequencing (NGS) by targeted sequencing can detect novel genes. We aimed to use NGS to test the concordance between cfDNA and tumor DNA in metastatic CRCs. A total of 95 paired tumor and peripheral blood samples from metastatic CRC patients were included. The tumor DNA and cfDNA were analyzed with a 10-gene NGS panel (Illumina HiSeq2500 system). The median number of mutations in tumor samples was 3 (range 0-7). The most commonly mutated gene was TP53 (63.2%), followed by APC (49.5%), KRAS (35.8%) and FAT4 (15.8%). The concordance of mutation patterns in these 10 genes was as high as 91% between cfDNA and tumor samples in these metastatic CRC patients. A sensitivity of 88.2% and specificity of 100% was found when using KRAS mutation status of cfDNA to predict KRAS mutation in tumor tissue. For tumor DNA with TP53, KRAS, or APC mutations, right-sided CRCs were more likely to develop peritoneal metastases, while for tumor DNA with TP53 mutations, left-sided tumors were more likely to have lung metastases. For cfDNA with TP53 or KRAS mutations, right-sided CRCs were more likely to have peritoneal metastases. Due to the high concordance of mutation patterns between cfDNA and tumor samples, monitoring the mutation pattern of cfDNA may be applicable in the treatment of metastatic CRC.
