    Area of Science:

    • Pharmacology and Oncology
    • Biomedical Engineering
    • Computational Biology

    Background:

    • Effective drug delivery to all tumor cells is crucial for cancer treatment success.
    • Tumor heterogeneity, including perfusion and oxygenation variations, poses significant challenges to drug accessibility.
    • Understanding drug distribution within tumors is essential for optimizing therapeutic strategies.

    Purpose of the Study:

    • To model and simulate drug delivery dynamics within tumor microenvironments.
    • To investigate the accessibility of tumor cells to anticancer agents.
    • To analyze drug distribution from well-perfused to hypoxic tumor regions.

    Main Methods:

    • Development of computational models for drug delivery simulation.
    • Analysis of drug transport from tumor capillaries to tumor cells.
    • Simulation of drug delivery for BCNU (anticancer agent) and misonidazole (hypoxic cell radiosensitizer).

    Main Results:

    • The study presents models for simulating drug delivery within tumors.
    • It addresses drug distribution challenges, particularly to hypoxic regions.
    • Simulations provide insights into the behavior of BCNU and misonidazole in tumor environments.

    Conclusions:

    • Computational modeling is a valuable tool for understanding and optimizing anticancer drug delivery.
    • Addressing drug accessibility to all tumor cells, including hypoxic ones, is critical.
    • The developed models can aid in designing more effective cancer therapeutic strategies.
