AIM
The 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.
BACKGROUND
Stereotactic 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 METHODS
This 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.
RESULTS
The liver SBRT treatment course implemented in the GPCC consists of three fractions to deliver a total of 45 Gy. Fraction delivery details with description of patient positioning (localization of liver metastasis) are presented below.
CONCLUSIONS
The 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.
目的
本研究的主要目的是对波兰波兹南大波兰癌症中心（GPCC）实施的肝脏立体定向体部放射治疗（SBRT）方案进行技术描述并展示其特性。
背景
肝脏转移瘤的立体定向体部放射治疗（SBRT）是一种非侵入性治疗选择，能够以高剂量照射体内的小目标。
材料与方法
本研究介绍了我们基于直线加速器的肝脏SBRT方案的详细情况。特别强调了基准标记植入、患者准备（CT扫描、固定）、治疗计划及其实施。
结果
GPCC实施的肝脏SBRT治疗疗程包括三次分割照射，总剂量为45 Gy。以下列出了每次分割照射的详细情况以及患者定位（肝脏转移瘤的定位）描述。
结论
关于GPCC基于直线加速器的肝脏SBRT程序步骤的假设经文献验证表明，它们具有有效且对患者友好实施的潜力。
