Summary
This study introduces personalized chemoimmunotherapy (chemotherapy and immunotherapy) protocols for brain cancer, moving beyond fixed treatments. Mathematical modeling identified an optimal, adaptable treatment strategy for improved outcomes.
Area of Science:
- Mathematical Oncology
- Computational Biology
- Immunotherapy Research
Background:
- Standard chemoimmunotherapy protocols for brain cancer often use fixed dosages and time intervals.
- Personalized medicine approaches are increasingly important for optimizing cancer treatment efficacy.
- Mathematical modeling provides a framework for analyzing complex treatment dynamics.
Purpose of the Study:
- To develop and investigate a mathematical model for personalized chemoimmunotherapy in brain cancer.
- To compare various non-fixed treatment protocols (varying dosages and time intervals).
- To identify an optimal chemoimmunotherapy protocol through mathematical analysis.
Main Methods:
- Development of explicit and analytical functions to describe chemoimmunotherapy treatment dynamics.
- Parameter modification within the mathematical model to generate diverse treatment protocols.
- Application of the singular perturbed vector field (SPVF) method for system analysis.
- Investigation of model equilibrium points and their stability.
Main Results:
- An optimal chemoimmunotherapy protocol was identified through comparative analysis of different treatment strategies.
- The SPVF method successfully determined the hierarchy of the mathematical model's equations.
- Equilibrium points of the mathematical model were identified and their stability characteristics were analyzed.
Conclusions:
- Personalized chemoimmunotherapy protocols offer a flexible alternative to fixed treatment regimens for brain cancer.
- Mathematical modeling, particularly with the SPVF method, is a valuable tool for optimizing cancer treatment strategies.
- The study provides a foundation for developing adaptive and individualized brain cancer therapies.

Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.

Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...
