Purpose of the Study:
- To present a mathematical model for optimizing intratumoral chemotherapy administration.
- To support the application of microdialysis for personalized drug delivery.
- To discuss cancer biology factors influencing chemotherapy efficacy.
Main Methods:
- Development of a mathematical model integrating informatics tools and key parameters.
- Review of critical cancer biology aspects: tumor heterogeneity, drug resistance, and metastasis.
- Application of microdialysis for local drug administration.
Main Results:
- The mathematical model provides a framework for optimizing drug doses and delivery.
- Microdialysis demonstrates potential for increased local drug concentration.
