Stereotactic body radiotherapy is an effective treatment in reirradiating spinal metastases: current status and practical considerations for safe practice
Bibliographic record
Abstract
Spinal metastases are a relatively common manifestation in advanced cancer patients. Low-dose conventional radiotherapy has long been the mainstay of treatment under the assumption that patients have a limited life expectancy in the order of 3-6 months. However, with new developments in systemic therapies, patients are surviving longer than expected. As the spinal retreatment rates, secondary to conventional radiation, can approach 20-50%, retreatments are likely to be more frequent. Rather than a second course of even lower-dose conventional radiation, spine stereotactic body radiotherapy (SBRT) has been developed predominantly to overcome the limitations of conventional reirradiation. Spine SBRT permits a second course of high-dose radiation aimed at local tumor control while sparing the spinal cord, and other surrounding normal tissues, of a toxic dose. The focus of this review is to provide an overview of reirradiation spine SBRT, and address key issues surrounding safe and effective practice.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
