Early palliative care has been shown to improve the quality of life and even survival for patients with metastatic cancer. More and more supportive oncology teams in cancer centers now advocate for early integration of radiation therapy (RT) in a patient's palliative management course. While multiple randomized studies have evaluated the efficacy of different RT regimens in the treatment of symptomatic bone lesions, few studies have examined the impact of early, upfront RT for asymptomatic or minimally symptomatic (non- opioid dependent) spine metastases and its efficacy in preventing skeletal-related events (SREs). Since the pathophysiology of spinal metastatic disease is distinct from other bony metastatic disease, the proposed trial seeks to understand whether it is beneficial to patients with minimally symptomatic disease to undergo upfront RT to reduce the risks of SREs and their sequelae, including hospitalizations.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Standard of Care Systemic Therapy or Surveillance | Active Comparator | Patients randomized to arm 1 will undergo appropriate systemic therapy as determined by their oncology team. These patients will either continue the current therapy or be transitioned to a new standard of care therapy at the discretion of the treating oncologist. If randomized to arm 1, these patients may also undergo palliative radiation therapy for progressive or painful lesions (a skeletal related event as defined in the study) at the time of symptom development*(not upfront palliative radiation therapy) |
|
| Prophylactic Radiation Therapy | Experimental | Patients randomized to Arm 2 of the study will undergo upfront prophylactic radiotherapy to ≤ 5 highest risk bone metastases followed by standard of care, as defined by:
|
|
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Prophylactic Radiotherapy | Radiation | Radiation therapy will be delivered according to department standards. For this protocol, total dose and dose fractionation may be delivered at the discretion of the treating radiation oncologist according to department standards. All techniques including conventional, three-dimensional conformal radiation therapy (3D-CRT), intensity-modulated radiation therapy (IMRT), and stereotactic radiosurgery/stereotactic body radiation therapy (SRS/SBRT) techniques may be used. Image guidance at the time of treatment delivery to verify patient positioning may be chosen at the discretion of the treating radiation oncologist according to department standards. |
| Measure | Description | Time Frame |
|---|---|---|
| Number of patients who have skeletal-related events (SREs) | Number of skeletal related events (SREs), which will be defined as pathological fractures, spinal cord compression, or interventions (palliative RT, interventional procedures, or spine surgery) | 1 year |
| Measure | Description | Time Frame |
|---|---|---|
| Number of skeletal-related event (SRE) hospitalizations | Number of hospitalizations attributed to skeletal-related events (SREs) | 1 year |
| Pain-related quality of life | Pain-related quality of life using the Brief Pain Inventory (BPI) form. The BPI is a 17-item patient self-rating scale assessing demographic data, use of medications, as well as the sensory and reactive components of pain. The scale is from 0-10, and there are breakpoints between scores of 4 and 5 and between 6 and 7, indicating that mild pain correlates with scores of 1-4, moderate pain with 5-6, and severe pain with scores of 7-10. |

| Standard of care systemic therapy | Drug | Standard of care systemic therapy, including chemotherapeutics, targeted therapies, immunomodulatory agents, and hormonal therapies will be delivered at the discretion of the treating medical oncologist. Patients may receive systemic therapy concurrently and there are no restrictions on initiation of systemic agents after radiotherapy including immunotherapy and hormonal therapy, the timing of which will be determined by a consensus between the treating medical and radiation oncologists. |

| 3 months, 6 months, and 12 months, optionally within 1 week of a skeletal-related event (SRE) |
| Health care utilities and quality of life | Health care utilities and quality of life using the EuroQol Group EQ-5D-5L form and FACT-G questionnaires. It has been developed to generate a generic cardinal index of health, thus giving it considerable potential for future use in economic evaluation. The EQ-5D-5L is a two-part, patient-completed questionnaire. The first part consists of 5 items covering 5 dimensions including: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. Each dimension can be graded on 3 levels including: 1=no problems; 2= moderate problems; and 3=extreme problems. The second component is the visual analog scale, where the participant rates their own overall health on a scale of 0 (worst health) to 100 (best health). | 3 months, 6 months, and 12 months, optionally within 1 week of a skeletal-related event (SRE) |
| Pain-free survival (PFS) | Pain-free survival (PFS) is defined as the time from study entry to until the start of opioid use or until death. | Until 1 year |
| Overall survival (OS) | Overall survival (OS) is defined as the time from study entry until death. | Until 1 year |
| Adverse event frequency and severity | Evaluate CTCAE v5 toxicity events in the upfront RT arm by tabulating all toxicities and summarizing the CTCAE v5 scores. | 3 months, 6 months, and 12 months |
