Colorectal Neoplasia and Microbiota: Does Left Equal Right?

Many studies, including our own, have shown that colorectal cancer (CRC) is related to changes in the microbiome of the colon. However, there are limitations in most studies and questions remained unanswered. Some early data showing that the microbiome in the left vs right colon are different.
The aim of this study is to investigate the microbiome (including bacteriome, virome, and fungome) of adenoma/CRC comparing the left (distal to splenic flexure) vs right side (proximal to splenic flexure) of the colon.
