Colorectal microenvironment determines the prognosis of colorectal cancer.

ABSTRACT: Here we aimed to evaluate the feasibility of distinguishing colorectal microenvironments that support cancer cell growth from those that do not. We hypothesized that patients whose non-tumor-bearing tissue (NBT) obtained from the furthest margins of resected cancer specimens resembled the tumor had a poorer prognosis. Patients with colorectal cancer were divided into groups with tumor-supportive (TSM) or healthy microenvironments using bulk RNA sequencing data from 273 paired NBT and tumor samples. Patients in the TSM group exhibited significantly poorer 5-year recurrence-free survival and overall survival compared with those in the healthy microenvironment group. Pathway and 16S rRNA sequencing analyses revealed that NBT and tumors from the TSM group shared a microbiome composition, along
