Randomized Trial on Same-day SBRT and Surgical Stabilization for Symptomatic Spinal Metastases — BLEND  

Spinal Metastases Clinical Trial

Official title:
Stereotactic Body Radiotherapy and pedicLE Screw fixatioN During One Hospital Visit for Patients With Painful Unstable Spinal Metastases: A Randomized Trial (BLEND)

Clinical Trial Summary

The BLEND RCT aims to evaluate the (cost-)effectiveness of same-day SBRT and surgical stabilization with or without decompression for the treatment of symptomatic, unstable spinal metastases on physical functioning four weeks after the start of treatment, compared with the standard of care (surgery followed by radiotherapy as soon as the wound healed sufficiently).

Clinical Trial Description

Rationale: Currently, patients with unstable spinal metastases receive surgical stabilization with/without decompression followed by conventional radiotherapy (cRT) or stereotactic body radiotherapy (SBRT) as soon as wound healing allows (at least 1 week). Advancements in radiotherapy techniques makes preoperative radiotherapy possible with sparing of the soft tissues overlying the surgical field. This makes it possible to shorten or even eliminate the time interval between surgery and radiotherapy. This will result in shorter and less hospital visits, earlier pain relief from irradiation, and faster return to systemic therapy without an increase in wound complications due to the short interval between surgery and radiotherapy. Objective: The BLEND RCT aims to evaluate the (cost-)effectiveness of same-day SBRT and surgery for the treatment of symptomatic, unstable spinal metastases on physical functioning four weeks after the start of the treatment, compared with the standard of care (surgery followed by radiotherapy, i.e., CRT or SBRT). Study design: A phase II randomized controlled trial within the PRospective Evaluation of interventional StudiEs on boNe metastases (PRESENT) cohort including patients with bone metastases, according to the Trials within Cohorts (TwiCs) design. Study population: Patients with symptomatic (cervical, thoracic and/or lumbar) spinal metastases and impending spinal instability requiring radiotherapy and surgical stabilization with or without decompression. Intervention: SBRT (with active dose-sparing of the surgical site) and surgical stabilization with or without decompression within 24 hours. The control group will receive the standard of care, which is surgical stabilization with or without decompression followed by cRT or SBRT as soon as the wound is healed sufficiently. Main study endpoints: The primary endpoint is physical functioning at four weeks after the start of the treatment. Secondary endpoints are pain response, duration of pain relief, length of hospital stay, time to return to systemic therapy, neurological deterioration, adverse events (e.g. wound complications), quality of life and survival. In addition, we will study the cost-effectiveness. ;
