Clinical – Mixed sites & palliation

Conclusion: Both the elective and involved target SSRS met the pre-specified criteria at 6 months. With longer follow-up, EF might be the preferable SSRS target volume owing to its lower treatment failure rate. Delineation guideline proposed by ISRC should be the standard of care for SSRS.

Additionally, the study explores the relationship between pain catastrophizing scores and treatment outcomes. Material/Methods: A cohort of 41 patients with bone metastases, undergoing PRT and receiving supplementary PE, was evaluated. PE sessions were integrated into the treatment timeline, with assessments of pain, satisfaction, and retention conducted at several points up to six months post-treatment. Pain relief was measured using the Numeric Rating Scale (NRS), and retention of educational content was assessed through follow-up surveys. The Pain Catastrophizing Scale (PCS) was used to analyze the patients' negative pain-related thoughts and their potential impact on treatment outcomes.
