In addition to the biomarker analysis, the review makes important recommendations for the routine monitoring of these biomarkers in CRC patients, especially those at higher risk for VTE. Furthermore, it discusses the integration of these biomarkers into clinical VTE risk prediction models, advocating for personalized and targeted thromboprophylaxis strategies. The review also explores future research directions, emphasizing the potential of antiplatelet and anticoagulant therapies in improving the prognosis of CRC patients by reducing thromboembolic events.
