NCT05038124

Brief Summary

The purpose of this study is to test the safety of stereotactic body radiation therapy (SBRT) followed by surgical stabilization within 1 week. All participants will have metastatic cancer in the bone (bone metastases), and they will be at risk of pathologic fracture (broken bone caused by a disease). Another purpose of this study is to see if the treatment approach of SBRT followed by surgical stabilization within 1 week prevents cancer from returning to the bone.

Outcome Measures

Primary Outcomes (1)

  • risk of major wound complications

    Major wound complications are defined as reoperation for wound revision, clinically diagnosed surgical site infection, readmission for wound care, or prolonged (\>3 weeks postoperatively) active wound care.

    6 weeks after preoperative SBRT

Secondary Outcomes (1)

  • rate of local control

    1 year

Study Arms (1)

Preoperative Stereotactic Body Radiotherapy (SBRT)

EXPERIMENTAL

Target lesions will be treated with preoperative SBRT consisting of biologically effective dose (BED10) of 50.4 - 81.6 Gy delivered in either three fractions or a single fraction. Active sparing of the intended surgical approach will be incorporated into the radiation plan by creating an avoidance structure. Surgical stabilization will proceed within 1 week of completion of radiotherapy. Pathologic specimens will be obtained intraoperatively via existing surgical access for histologic and molecular analysis. An optional research MRI with perfusion will be performed within 30 days prior to radiation simulation and within one-week after radiation therapy using 3T scanner. If patients receive radiation simulation at a non-MSK Manhattan site, MRI with Perfusion will not be performed.

Radiation: Preoperative Stereotactic Body Radiotherapy (SBRT)

Interventions

Target lesions will be treated with preoperative SBRT consisting of biologically effective dose (BED10) of 50.4 - 81.6 Gy delivered in either three fractions or a single fraction.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Diagnosis of metastatic cancer with radiologic evidence of skeletal metastases
  • Treatment target involving humerus, radius, pelvis, sacrum, femur, or tibial diaphysis
  • Age at enrollment ≥18 years
  • Life expectancy \>3 months
  • Ability to tolerate radiation simulation and treatment with immobilization of involved anatomic site
  • Surgical candidate, as determined by the treatment team
