Effectiveness of Robotic Stereotactic Radiotherapy in Patients Undergoing Re-irradiation: A Review

Stereotactic ablative radiotherapy (SABR) is a possible treatment option for patients who develop recurrence within or at the edge of previously irradiated volume. Robotic stereotactic result technological advances in robotic precision, real-time imaging, non-invasive, highly customizable plan, and delivery with sub-millimeter accuracy. This article reviews radiobiologic, technical, clinical aspects robotic-based SABR re-irradiation various anatomical sites. An extensive literature search was performed to identify articles on utilization undergoing re-irradiation. The reported prescription dose fractionation data along outcomes such as overall survival, local control rates, toxicities were qualitatively reviewed. findings consistently indicate that using provides encouraging survival rates minimal toxicity setting sites delivered locally non-invasive means where other options are scarce.
