Comparing SingLe- Vs Multi-Fraction Spine STereotActic Radiosurgery in Spinal Metastases

July 15, 2025 updated by: Stanford University

A Randomized Phase III TriaL Comparing SingLe- Versus Multi-Fraction Spine STereotActic Radiosurgery for Patients With Spinal Metastases (ALL-STAR)

The goal of this study is to determine whether fractionated Stereotactic radiosurgery (SRS) for spine metastases is associated with improved local tumor control compared to single-fraction SRS. Patients will be randomized to treatment with spine SRS using either 22 Gy in 1 fraction or 28 Gy in 2 fractions.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Tumor control
Time Frame: 1 year
To determine whether fractionated Stereotactic Radiosurgery (SRS) for spine metastases is associated with improved local tumor control at 1 year following SRS compared to single-fraction SRS.
1 year

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Euro-QOL EQ-5D-3L health-related quality of life questionnaire
Time Frame: 2 years
To compare health-related quality of life (EQ-5D-3L) following SRS and assess patient-reported health related quality of life pertaining to mobility, self-care, usual activities, pain, and anxiety.
2 years
European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30 health-related quality of life scale score
Time Frame: 2 years
To compare health-related quality of life (EORTC QLQ-C30) following SRS and assess patient-reported health related quality of life pertaining to overall health and quality of daily life.
2 years
EORTC QLQ-BM22 health-related quality of life questionnaire
Time Frame: 2 years
To compare health-related quality of life (EORTC QLQ-BM22) following SRS and assess patient-reported health related quality of life pertaining to pain associated with performing activities of daily life.
2 years
Pain Score
Time Frame: 1-2 weeks after SRS and 1, 3, 6, 12, 18, and 24 months following SRS
Pain associated with the treated area will be assessed by asking patients to rate their pain on a 0-10 scale ("no pain" to "pain as bad as you can imagine")
1-2 weeks after SRS and 1, 3, 6, 12, 18, and 24 months following SRS
Medication Intake
Time Frame: 1-2 weeks after SRS and 1, 3, 6, 12, 18, and 24 months following SRS
Collect medications taken within the last 24 hours.
1-2 weeks after SRS and 1, 3, 6, 12, 18, and 24 months following SRS
Number of participants with CTCAE grade grade 2 or higher adverse effects
Time Frame: 1 year
To determine 1-year rate CTCAE grade 2 or higher adverse effects, following SRS
1 year
Rate of vertebral compression fracture
Time Frame: 1 year
To determine 1-year rate of vertebral compression fracture (VCF), following SRS
1 year
Rate of local failure
Time Frame: 2 years
