An agent-based model for studying the temperature changes on environments exposed to magnetic fluid hyperthermia

Area of Science:

• Biomedical Engineering
• Computational Biology
• Oncology

Background:

• Magnetic fluid hyperthermia (MFH) is an emerging cancer therapy.
• Controlling spatial temperature distribution remains a significant challenge in MFH treatments.
• Glioblastoma multiforme (GBM) is a target for MFH due to its accessibility.

Purpose of the Study:

• To develop an agent-based model simulating temperature changes during MFH.
• To evaluate the influence of a specific thermal parameter (α) and magnetic field intensity (H) on tumor temperature dynamics.
• To understand the mechanisms of temperature stabilization in the tumor environment during MFH.

Main Methods:

• Development of an agent-based model for MFH simulation.
• Incorporation of thermodynamic properties of magnetic fluids and biological tissues.
• Parameterization of the model based on clinical protocols for glioblastoma multiforme.
• Evaluation of the impact of the thermal parameter (α) and magnetic field strength (H) on temperature evolution.

Main Results:

• The model accurately reproduced experimental temperature changes reported in MFH literature.
• Local energy diffusion interactions were identified as crucial for temperature stabilization within the tumor.
• The α-parameter was confirmed as a critical factor influencing temperature control and heating rate.
• External magnetic field intensity (H) also affects temperature dynamics.

Conclusions:

• The developed agent-based model provides a valuable tool for simulating and understanding MFH temperature dynamics.
• The α-parameter is a key controllable factor for optimizing MFH treatment efficacy and safety.
• Further research can utilize this model to refine MFH protocols for various cancers, including GBM.
