The genetic analysis of circulating tumor DNA in blood of the digestive cancer patients to investigate the  prognostic factors of metastasis and reccurence.
A Darwinian evolutionary shift occurred early in the neutral evolution of advanced colorectal carcinoma (CRC) and copy number aberrations (CNA) were essential in the transition from adenoma to carcinoma. Subsequent to the primary evolution, we now focus on the evolutionary principle of the genome to foster postoperative recurrence of CRC. SO, We compared CNA, single nucleotide variance (SNV), RNA sequences between 8 primary and 11 metastatic sites from 10 CRCR cases.The Data Access Committee of the National Bioscience Database Center (NBDC) approved that this personal genetic data were made published according to NBDC data sharing guidelines (http://humandbs.biosciencedbc.jp/).
