Clinical Report: Collaborative Machine Learning Models for CRC Survival Forecasting

Overview

This study developed a collaborative machine learning approach to identify key prognostic factors in colorectal cancer (CRC) patients, integrating clinical, pathological, serological, and demographic variables.

Background

Colorectal cancer (CRC) presents significant challenges in prognostic prediction due to tumor heterogeneity and limitations of the conventional TNM staging system. Accurate prognostic tools are essential for tailoring individualized treatment strategies.

Data Highlights

Key Findings

• Six central prognostic features identified: M stage, N stage, Cystatin C, Homocysteine, γ-Glutamyl Transferase, and age.
• Cox regression confirmed independent associations of these features with overall survival (OS) and progression-free survival (PFS).
• Nomograms for OS and PFS demonstrated calibration and discrimination (OS C-index: 0.730; PFS C-index: 0.722).
• AUCs for OS and PFS exceeded 75% and 77%, respectively.
• Decision curve analysis indicated clinical utility compared to conventional pathological staging.
• Internal validation confirmed predictive performance of the nomograms.

Clinical Implications

The integration of multiple prognostic factors into nomograms may enhance survival predictions for CRC patients.

Conclusion

This study presents collaborative machine learning models for prognostic prediction in colorectal cancer.
