Case 1
Advanced Radiation Therapy Improves Local Tumor Control
A 52 year-old male patient was diagnosed with an osteosarcoma of L1.
Therapy
The expert panel’s decision for the best possible therapeutic success: tumor resection, dorsal stabilization, chemotherapy, and adjuvant proton therapy. In order to improve the success of radiation therapy, implants made of BlackArmor® Carbon/PEEK were used.
Anterior corpectomy and VBR with the KONG®-TL VBR System and dorsal percutaneous stabilization with the VADER® Pedicle System
With the artifact-free BlackArmor® Carbon/PEEK implants, proton therapy could be both planned and delivered with high precision. The material’s radiolucency enabled homogeneous application of the radiation dose in the tumor tissue. At the same time, the surrounding organs at risk were protected.
Six months after the intervention, the patient presents for follow-up with no complaints and no radiologically detectable recurrence.
