Differences in tissue-associated bacteria between metastatic and non-metastatic colorectal cancer

Abstract

The bacterial composition of tumor and tumor adjacent tissue from the metastatic CRC group was different from that of the non-metastatic CRC group; in particular, <i>Bacteroides</i> was increased, and <i>Streptococcus</i> was decreased. These findings are helpful to further reveal the mechanism of CRC metastasis and provide new ideas for the clinical diagnosis and treatment of CRC metastasis.
