In 2019, our institution became the second in the world to go live with GammaPod (Xcision Medical Systems, LLC, Columbia, MD), a device dedicated for stereotactic radiation therapy of breast cancer, with breast immobilization, real-time imaging, and highly-conformal dosimetry. At our institution, GammaPod is used for 5-fraction adjuvant partial breast irradiation, single-fraction tumor cavity boost before whole-breast irradiation, single-fraction preoperative radiation, and (in poor surgical candidates), single-fraction definitive radiation. Here, we describe our workflow, observed procedure step times, and homegrown techniques for improved efficiency in our institutional experience of 93 patients treated between 2019 and 2021.
2019年,我们机构成为世界上第二家启用GammaPod(Xcision Medical Systems, LLC,哥伦比亚,马里兰州)的机构,该设备专为乳腺癌立体定向放射治疗而设计,具备乳腺固定、实时成像和高度适形剂量测定功能。在我们机构,GammaPod用于5次分割的辅助性部分乳腺照射、全乳照射前单次分割的瘤腔推量、单次分割的术前放疗,以及(针对手术条件较差的患者)单次分割的根治性放疗。在此,我们描述了我们的工作流程、观察到的操作步骤时间,以及在2019年至2021年期间治疗的93例患者的机构经验中提高效率的自主技术。
