AimThe main purpose of this work is to give a technical description and present the properties of the liver SBRT protocol implemented in the Greater Poland Cancer Centre (GPCC) in Poznan, Poland.BackgroundStereotactic body radiation therapy (SBRT) for liver metastasis is a non-invasive therapeutic option which enables irradiation of a small target in the body with a high dose.Materials and methodsThis study presents details of our linac-based liver SBRT protocol. Special emphasis has been placed on fiducial implantation, patient preparation (CT scanning, immobilization), treatment planning, and its implementation.ResultsThe liver SBRT treatment course implemented in the GPCC consists of three fractions to deliver a total of 45Gy. Fraction delivery details with description of patient positioning (localization of liver metastasis) are presented below.ConclusionsThe literature validation of the assumptions concerning the steps of the GPCC linac-based liver SBRT procedure show their potential for an effective and patient friendly implementation.
