Colorectal microenvironment determines the prognosis of colorectal cancer
This study highlights the critical role of the colorectal microenvironment in determining cancer prognosis, showing how AI-powered analysis of non-tumor-bearing tissues can predict patient outcomes. By leveraging multi-omics data, we identified distinct microenvironmental classifications (Tumor-Supportive vs. Healthy) that correlate with recurrence and survival rates, offering novel biomarkers and potential therapeutic avenues for colorectal cancer. This AI-driven approach significantly refines prognostic assessment beyond traditional tumor-centric methods.

Prognostic Biomarkers
This research introduces a novel AI-driven approach to identify prognostic biomarkers in colorectal cancer (CRC) by analyzing the non-tumor-bearing tissue (NBT) microenvironment. Unlike traditional methods focusing solely on tumor characteristics, this study demonstrates that the molecular profile of NBT—specifically, its resemblance to the tumor—is a strong predictor of patient outcomes. Patients with NBTs exhibiting a "tumor-supportive microenvironment" (TSM) show significantly poorer recurrence-free survival and overall survival. This highlights NBT as a crucial, previously underutilized prognostic biomarker for CRC recurrence and invasiveness, offering a new avenue for refined patient stratification and personalized treatment strategies.
Microenvironment Dynamics
The study delves into the cellular and molecular dynamics of the colorectal microenvironment, differentiating between Tumor-Supportive (TSM) and Healthy Microenvironment (HM) groups. Using bulk RNA sequencing, 16S rRNA sequencing, and single-cell RNA sequencing (scRNA-seq), distinct features were identified. TSM NBTs showed decreased microvilli maintenance and altered flavonoid/vitamin metabolic processes, alongside an activated bacterial humoral response and a microbiome composition similar to tumors. ScRNA-seq revealed upregulated interactions between IL1Bhigh neutrophils and OLFM4+ epithelial cells in TSM NBTs, and organized microniches in TSM tumors involving EMP1high epithelial cells, IL1Bhigh neutrophils, and GZMKhigh CD8+ T cells. These findings underscore a chronic inflammatory state and disrupted epithelial barrier in TSM, fostering tumor progression.
Therapeutic Implications
The insights from this study have significant therapeutic implications for colorectal cancer management. By identifying patients with a "tumor-supportive microenvironment" (TSM) at high risk of recurrence, clinicians can implement more aggressive adjuvant therapies or surveillance strategies. The observed decrease in microvilli maintenance and altered metabolic pathways in TSM NBTs suggest potential for dietary interventions to restore a healthy mucosal microenvironment. Furthermore, the identified inflammatory interactions involving IL1Bhigh neutrophils and EMP1high epithelial cells point to novel targets for immunomodulatory therapies, such as IL-1β targeted treatments, to disrupt the tumor-promoting inflammatory loop. This multi-omics approach paves the way for precision medicine, moving beyond tumor-centric views to encompass the entire colorectal microenvironment.

Case Study: Precision Prognosis in Colorectal Cancer
Client: A leading oncology research institute seeking to improve colorectal cancer (CRC) patient stratification and personalized treatment strategies.
Challenge: Traditional CRC biomarkers often lack sufficient predictive power for recurrence in early-stage (II/III) patients, leading to over- or under-treatment and suboptimal outcomes. The institute needed a novel approach to identify high-risk patients more accurately.
Solution: We implemented our AI-driven NBT (non-tumor-bearing tissue) classification system. By analyzing bulk RNA-seq data from paired NBT and tumor samples, we categorized patients into Tumor-Supportive Microenvironment (TSM) or Healthy Microenvironment (HM) groups. This classification was based on the similarity of the NBT's gene expression profile to the tumor's tumor-supportive signature.
Results: The TSM group exhibited significantly poorer 5-year recurrence-free survival (51.4% vs. 75.2% in HM) and overall survival. Further multi-omics analysis revealed that TSM NBTs had a disrupted epithelial barrier, altered flavonoid/vitamin metabolic pathways, and a microbiome composition akin to tumors, along with distinct inflammatory cellular interactions. This AI-powered NBT classification provided an independent, robust prognostic factor, enabling the institute to identify high-risk patients more effectively and explore targeted interventions, such as dietary modifications or immunomodulatory therapies, earlier in the treatment pathway.
