About this trial

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).

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Symptomatic (cervical, thoracic and/or lumbar) spinal metastases from solid tumors and (impending) spinal instability requiring radiotherapy and surgical decompression and/or stabilization

Histologic proof of malignancy or radiographic/clinical characteristics indicating malignancy beyond reasonable doubt

Radiographic evidence of spinal metastases

Participation in PRESENT cohort, including consent for randomization into future trials

Disqualifiers

SBRT cannot be delivered, e.g. in patients who cannot lie on the treatment table because of pain

Routine surgical decompression and/or stabilization and radiotherapy cannot be performed, e.g., multiple spinal metastases requiring surgical bridging of more than five vertebral levels and/or requiring radiotherapy on more than one location

Prior surgery or radiotherapy to the index level(s)

Multiple myeloma

Trial outcomes

Primary outcomes

1

Physical functioning

Physical functioning is a functional scale from the EORTC QLQ-C15-PAL questionnaire. Patients rate each item on a 4-point Likert scale ranging from 1 (not at all) to 4 (very much), and scale scores were linearly transformed to a 0-100 scale. A higher score on the functional scale indicates better functioning.

Time frame
at 4 weeks after the start of treatment

Secondary outcomes

1

Pain response

Pain response is defined as 1) a decline in worst pain score of at least two points on an NRS of ten at the treated site without increase in analgesic use, or 2) an analgesic decrease of at least 25% without an increase in pain score. Worst pain score will be measured with the Brief Pain Inventory.

Time frame
at 2, 4, 6 and 8 weeks, and 3 months after the start of treatment
2

Duration of pain relief

Duration of pain relief as measured by the Brief Pain Inventory (BPI).

Time frame
up to 3 months
3

Duration of hospital stay

Duration of hospital stay in days

Time frame
up to 3 months
4

Days until return to systemic treatment

Days until return to systemic treatment

Time frame
up to 12 months

Cost-effectiveness

If same-day SBRT and surgery is more costly and more effective than the standard of care, an incremental cost-effectiveness ratio (ICER) will be calculated by dividing the extra QALYs by the extra effects. This will give an estimation of the extra costs that are needed to gain one QALY. If this is below the cost-effectiveness threshold, same-day SBRT and surgery is deemed cost-effective. If either same-day SBRT and surgery or the standard of care is less costly and more effective than its alternative, it dominates this alternative and no ICER is necessary to determine cost-effectiveness.

Time frame
up to 12 months
