Prophylactic Radiotherapy of MInimally Symptomatic Spinal Disease (PROMISSeD)
Spine Metastases
About this trial
This is an interventional supportive care trial for Spine Metastases focused on measuring Radiotherapy (RT), Palliative radiotherapy, High-risk asymptomatic spine metastases, Minimal asymptomatic spine metastases
Eligibility Criteria
Inclusion Criteria:
- Histologically-confirmed solid tumor malignancy with greater than 5 sites of metastatic disease detected on cross-sectional imaging.
Has high-risk bone metastases that are asymptomatic or minimally symptomatic (not requiring opioids). High risk metastases are defined as:
- Bulkiest sites of spinal osseous disease ≥ 2cm,
- Disease at junctional levels, including the thoracic apex (Occiput to C2, C7-T1, T12-L2, and L5- S1)
- Disease with posterior element involvement, including interspinous, unilateral, or bilateral facet joints.
- Vertebral body compression deformity > 50%.
- Eastern Cooperative Oncology Group (ECOG) performance status 0 - 2.
- Age ≥ 18 years.
- Able to provide informed consent.
- Patients at reproductive potential must agree to practice an effective contraceptive method. Women of childbearing potential must not be pregnant or lactating.
Exclusion Criteria:
- Previous RT to the intended treatment site that precludes developing a treatment plan that respects normal tissue tolerances.
- Serious medical co-morbidities precluding RT.
- Pregnant or lactating women.
- Target lesion(s) is/are complicated bone metastases that include clinical or radiological evidence of spinal cord compression or impending pathological fracture.
- Leptomeningeal disease.
- Patients whose entry to the trial will cause unacceptable clinical delays in their planned management.

Arms of the Study
Arm 1
Arm 2
Active Comparator
Experimental
Standard of Care Systemic Therapy or Surveillance
Prophylactic Radiation Therapy
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)
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: Bulkiest sites of disease ≥ 2cm (can include paraspinal disease extension) Disease in junctional spine (Occ-C2, C7-T1, T12-L1, L5-S1) Disease with posterior element involvement (facet(s), interspinous) Compression Deformity > 50%
