A Physical Framework to Control Cancer Cell Heterogeneity and Plasticity

We propose a physics-based framework in which cancer cell state is defined by position and velocity in a continuous space of directly measurable physical variables-cell surface area (S) and volume (V)-and motion through S-V space as an interpretable proxy for plasticity. Therapy generates S-V vector fields that govern trajectories, enabling the design of drug combinations to steer heterogeneous cell populations toward nonviable states, offering a predictive and physically interpretable alternative to therapies directed against oncogenic mutations and/or predefined cell subpopulations.
