Patterns of Intraosseous Recurrence following Stereotactic Body Radiotherapy for Coxal Bone Metastasis

Patterns of intraosseous failure in 17 patients treated with stereotactic body radiation therapy (SBRT) for coxal bone metastases were analyzed retrospectively. Although SBRT achieved good local control at the target, marginal/out-of-field recurrences in the coxal bone were observed in 7 cases. Tumor recurrence occurred at an average distance of more than 30 mm from the initial metastasis.
