  • Bone metastases in patients with systemic cancer frequently manifest in the spine. The median overall survival of patients with bone metastases is only 7-9 months1 while some of these patients (with primary entities responsive to systemic treatment) can survive more than a decade.
  • In order to instantly stabilize and sterilize the affected vertebral bodies, combined kyphoplasty and intraoperative radiotherapy (Kypho-IORT) provides a promising local treatment option as alternative to the external beam radiotherapy (EBRT) as standard-of-care.
  • In this long-term outcome assessment, the currently largest existing patient cohort of 104 patients treated with Kypho-IORT between 2009 and 2019 are evaluated. The patients received Kypho-IORT using a needle applicator directly within the affected vertebral bodies of the thoracic, lumbar or sacral spine either as part of [...]
