    Area of Science:

    • Oncology
    • Surgical Techniques
    • Biomedical Engineering

    Background:

    • Tumor research often requires controlled environments.
    • Studying tumors ex vivo presents unique challenges in maintaining viability.

    Purpose of the Study:

    • To describe a detailed procedure for the ex vivo perfusion of a tumor as an isolated organ.
    • To establish a method for separating a tumor from its host while maintaining vascular integrity for perfusion.

    Main Methods:

    • Preparation of the tumor-host connection via a single artery and vein.
    • Transfer of the tumor to a specialized ex vivo perfusion system.
    • Establishment of the perfusion circuit, perfusate composition, and control of vascular and metabolic parameters.
