Area of Science:

  • Computational Biology
  • Mathematical Modeling
  • Oncology

Background:

  • Brain tumor growth is complex and challenging to model accurately.
  • Existing models often lack the ability to capture macroscopic behavior from microscopic parameters.

Purpose of the Study:

  • To develop a novel and versatile three-dimensional cellular automaton model for brain tumor growth.
  • To demonstrate the model's ability to simulate realistic tumor behavior using minimal parameters.
  • To showcase the model's flexibility in simulating the emergence of new tumor clones.

Main Methods:

  • Development of a novel 3D cellular automaton model.
  • Incorporation of microscopic parameters to simulate macroscopic tumor behavior.
  • Simulation of Gompertzian growth and tumor composition dynamics.

  • Inclusion of novel features: adaptive grid lattice, isotropic lattice, and new cell modeling definitions.

    • Main Results:

    • The model accurately simulates Gompertzian growth over a wide range of tumor sizes (three orders of magnitude).
    • Predicted tumor composition and dynamics align with existing medical literature.
    • Demonstrated model flexibility by simulating the emergence and dominance of a second tumor clone with a different genotype.

    Conclusions:

    • A versatile 3D cellular automaton model can realistically simulate brain tumor growth using microscopic parameters.
    • The model accurately predicts tumor growth dynamics, composition, and the emergence of genotypic variations.
    • This novel modeling approach offers a flexible platform for studying brain tumor progression and heterogeneity.
