The Supportive Care Needs of Cancer patients Receiving Radiation Therapy: A Retrospective Review of Radiation Therapists’ Referral Practices during the Treatment Delivery Process at a Large Cancer Centre

were most commonly located in the pelvis (44/106; 41.51%) and almost half of the bone metastases were sclerotic (52/106; 49.06%) in nature. The most common dose fractionation schemes were 30 Gy/5 (30.2%) and 35 Gy/5 (42.5%). Local recurrence was observed in 8/106 (7.69%) of the lesions. On bivariate analysis, a significant association was found between local recurrence and PTV volume (p1⁄40.02). Fracture occurred in the region of treatment in 9/106 (8.49%) of the treated lesions. No significant association was found between fracture and any of the patient or tumour factors analyzed including previous radiation to the site of treatment and size of PTV treated. Conclusion/Impact/Outcomes: Even across multiple sites of disease and histologies, SBRT achieved excellent local control for non-spine bone metastases with an acceptable risk of fracture.
