Area Of Science
- Oncology
- Mathematical Biology
- Computational Medicine
Background
- Metastatic cancer has a 90% mortality rate, necessitating a deeper understanding of its mechanisms.
- Mathematical modeling offers a quantitative approach to study metastasis and inform treatment strategies.
Purpose Of The Study
- To develop a mathematical model predicting secondary metastatic sites based on organ networks and blood flow.
- To explore the relationships between metastasis, blood flow dynamics, and cancer cell diffusion.
- To investigate the impact of anisotropic diffusion on metastatic efficiency.
Main Methods
- Utilized a partial differential equation-based mathematical model.
- Embedded the model within a network representing organs and vasculature.
- Analyzed the correlation between model predictions and clinical data for various cancer types.
Main Results
- Model predictions showed good correlation with clinical data for gut and liver cancers.
- An inverse relationship was observed between blood velocity and cancer cell concentration in secondary organs.
- Anisotropic diffusion, characterized by directional diffusivity, decreased metastatic efficiency, aligning with glioma observations.
Conclusions
- The developed model provides a valuable framework for simulating cancer progression and metastasis.
- It clarifies the influence of blood flow and diffusion on the global spread of cancer.
- Offers insights for clinical practitioners and researchers studying cancer metastasis and progression.

Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
