Post-Operative Spine Stereotactic Body Radiotherapy (SBRT): A critical review to guide practice

A partir d'une revue de la littérature publiée entre 1966 et 2015 (52 articles), cette étude analyse, par rapport à une radiothérapie conventionnelle, les indications, les pratiques et les résultats de la radiothérapie corporelle stéréotaxique post-opératoire dans le traitement des métastases spinales

Résumé en anglais

Post-operative stereotactic body radiotherapy (SBRT) for metastatic spinal tumors is increasingly being performed in clinical practice. Whereas the fundamentals of SBRT practice for intact spinal metastases are established, there are as yet no comprehensive practice guidelines for the post-operative indication. In particular, there are unique considerations for patient selection and treatment planning specific to post-operative spine SBRT that are critical for safe and effective management. The purpose of this critical review is to discuss the rationale for treatment, describe those factors impacting surgical decision making, introduce modern surgical trends, and summarize treatment outcomes for both conventional post-operative conventional external beam radiotherapy and post-operative spine SBRT. Lastly, an in-depth practical discussion with respect to treatment planning and delivery considerations is provided to help guide optimal practice.
