Microbiome alterations in mismatch-repair deficient metastatic colorectal cancer patients
Abstract Colorectal cancer (CRC) is the second leading cause of cancer-related death worldwide. Many efforts have been made to stratify CRC cases, from investigating the genomic characteristics of the tumor to – more recently – considering the gut microbiome. Differences in the composition of the gut microbiome occur along CRC stages and according to primary tumor location. The microbiome links with other tumor characteristics remain underinvestigated, including those related to microsatellite instability, that hav …
