Median Squared Error (SD) for excellent model fit
The Schättler mathematical framework successfully fitted to individual patient data, achieving very low median squared errors (0.003 for SD, 0.007 for PD) at day 56. This demonstrates the model's high accuracy in capturing short-term tumour dynamics under metronomic chemotherapy.
Key Biomarkers & System Dynamics: Unpacking Complex Interactions
Explore the identification of the growth control parameter ξ as a potential biomarker and understand the multi-component dynamics of tumour growth, angiogenesis, and immune response as modeled.
0.115
Critical Growth Control Parameter (ξ) identified for treatment response
The growth control parameter ξ emerged as a potential biomarker, showing distinct ranges for stable disease (0.066-0.153) and progressive disease (0.093-0.177), with a critical threshold identified at approximately 0.115. This suggests ξ could be a key indicator for treatment response.

Metronomic Chemotherapy Effects
The model uses three coupled Ordinary Differential Equations (ODEs) to represent tumour growth (p), angiogenesis (q), and immune response (r). It integrates direct and indirect effects of metronomic chemotherapy, demonstrating the complex interplay of these biological processes.
Therapeutic Impact: Limitations of Current Approaches
This section investigates the consistently low values of drug effect parameters, suggesting inherent limitations in current metronomic chemotherapy for metastatic gastrointestinal cancer.
0.003
Lowest Drug Effect Parameter (φ1) observed across treatment mechanisms
Drug effect parameters (φ1, φ2, φ3) consistently showed low values (0.003–0.09), aligning with modest clinical benefits in trials for metastatic gastrointestinal cancer. This suggests inherent limitations in the biological mechanisms targeted by metronomic approaches for mCRC.
Clinical Translation Challenges: Bridging Model to Patient Outcome
Delve into the complexities of predicting Progression-Free Survival (PFS) at the individual patient level, despite strong population-level correlations, emphasizing the heterogeneity of metastatic disease.
Challenge in PFS Prediction
While a significant inverse relationship (r = -0.71) was observed between predicted tumour size change and Progression-Free Survival (PFS) at the aggregate level, the model struggled to accurately predict PFS for individual patients. This highlights the inherent complexity and heterogeneity of metastatic disease, where early tumour dynamics alone may not suffice for long-term outcome prediction.
Despite moderate correlation (r=-0.71) at population level, individual PFS prediction remains challenging due to disease heterogeneity and the complexity of progression mechanisms, indicating factors beyond the model scope influence long-term outcomes.
