They are often employed for estimating physiological parameters, where we can distinguish between fixed and random effects, and they work particularly well for analyzing similar types of data. We apply mixed-effect modeling on experimental data, in which mice with breast cancer were treated with chemotherapeutic drugs. The mice are genetically identical, they had the same type of tumor, and they were treated with the same drug. The available data are the tumor volumes at specific time points and the doses of the injected drug. We fit our mathematical model to these experimental data; the parameters of that mathematical model are essentially the physiological parameters whose estimation is crucial for optimizing the therapy. To estimate the parameters, we apply a nonlinear mixed-effects model fitting to in vivo data. © 2025, Budapest Tech Polytechnical Institution.

Designing personalized therapies using different algorithms is crucial, especially during chemotherapy, to minimize the toxic effects on the patient and avoid resistance, thus ensuring a higher quality of life. In this work, we present an LSTM neural network that can quickly and accurately estimate the parameters of the tumor dynamics model based on noisy virtual patient data. In addition, we present a genetic algorithm designed for therapy optimization, which is able to predict the most appropriate personalized therapy based on the estimated parameters. In this work, we focus on finding the optimal hyperparameters of this genetic algorithm. Optimizing the hyperparameters is of fundamental importance in designing the best possible personalized therapy. © 2024, Budapest Tech Polytechnical Institution.
