The systematic review by Guevelou et al. examines the impact of stereotactic body radiotherapy (SBRT) on patients with metastatic castration-resistant prostate cancer (mCRPC) [1]. The authors analyze 19 relevant studies, predominantly retrospective, to assess the effectiveness of SBRT in improving progression-free survival (PFS) and biochemical progression-free survival (bPFS) in individuals experiencing metachronous oligoprogression, particularly when combined with androgen receptor pathway inhibitors. They report promising outcomes, with bPFS ranging from 9.5 to 17.9 months. While SBRT is noted for its tolerability and low incidence of severe toxicity, the authors emphasize that the overall evidence remains limited, highlighting the necessity for prospective trials to establish clearer clinical guidelines.
