Brief Summary

This phase II clinical trial studies how well thermal ablation and spine stereotactic radiosurgery work in treating patients with cancer that has spread to the spine (spine metastases) and is at risk for compressing the spinal cord. Thermal ablation uses a laser to heat tumor tissue and helps to shrink the tumor by destroying tumor cells. Stereotactic radiosurgery delivers a large dose of radiation in a short time precisely to the tumor, sparing healthy surrounding tissue. Combining thermal ablation with stereotactic radiosurgery may be a better way to control cancer that has spread to the spine and is at risk for compressing the spinal cord.

Detailed Description

PRIMARY OBJECTIVE:

I. To document the rate of local control at 6 months in patients who receive a combination of thermal ablation and stereotactic spine radiosurgery (SSRS) for spine metastases with moderate to severe epidural involvement.

SECONDARY OBJECTIVES:

I. To determine local control at 1, 3, 9, 12, 18, and 24 months, and to compare to a historical control where patients received only SSRS at these time points and at 12 months.

II. To document the extent of epidural tumor regression at 1, 3, 6, 9, 12, 18 and 24 months.

IIa. Calculate decrease in epidural tumor volume (by volumetric measurements). IIb. Calculate increase in thecal sac patency (by volumetric measurements and according to Bilsky method).

III. To determine overall survival at 6, 12, 18, and 24 months. IV. To assess changes in muscle strength, location and severity of spinal-related pain, sensory function, ability to ambulate, and neurological grading at 1, 3, 6, 9, 12, 18, and 24 months compared with pretreatment baselines.

V. To assess the effect of treatment on quality of life (QOL), measured at 1 month and every 3 months after with validated outcome measure tools.

VI. To describe adverse side effects after treatment and to descriptively correlate those effects with radiographic findings, pain control, and quality of life.

OUTLINE:

Patients undergo thermal ablation and computed tomography (CT)-guided SSRS via intensity-modulated radiation therapy on different dates within a 1-14 day window. The order of treatment is at the doctor's discretion.

After completion of study treatment, patients are followed up at 1, 3, 6, 9, and 12 months and then every 6 months.

Primary Outcome Measures
NameTimeMethod
Local tumor control rateAt 6 months

Kaplan-Meier estimates will be used.

Secondary Outcome Measures
NameTimeMethod
Overall survivalUp to 24 months

Kaplan-Meier estimates will be used.

Epidural control assessed by volumetric measurementsUp to 24 months

Extent of epidural tumor regression be determined by change in epidermal tumor volume and change in thecal sac patency (by volumetric measurements and according to Bilsky method). Kaplan-Meier estimates will be used. Cumulative incidence of epidural failure will be estimated failure treating death without failure as a competing risk. Propensity score analyses will be used to compare the thermal ablation cohort with a historical cohort.

Changes in quality of life (QOL) assessed by Brief pain inventory (BPI) formBaseline to 24 months

Participants are asked to assess the severity of pain and the impact of pain on daily functions. Severity of pain, including the pain location, worst pain in last 24 hours, least pain in last 24 hours, pain on average and pain right now. Range 0-10. A score of 0 would mean no pain and a score of 10 means the pain is as bad as you can imagine. Pain medications, amount of pain relief in the past 24 hours, and impact of pain on daily function, including general activity, mood, walking ability, normal work, relations with other people, sleep, enjoyment of life, and Range 0-10.

Local tumor controlUp to 24 months

Kaplan-Meier estimates will be used. Time to local failure will be monitored continuously using a Bayesian method. Cumulative incidence of local failure will be estimated failure treating death without failure as a competing risk. Propensity score analyses will be used to compare the thermal ablation cohort with a historical cohort where patients received only stereotactic spine radiosurgery (SSRS).

Changes in symptoms assessed by physical examinationBaseline to 24 months

The Physical exam includes general exam, (HEENT) Head, Eye, Ear, Nose and Throat evaluation, chest, heart, abdomen and extremities exam. Combined with the neurotically examination results, changes at 1, 3, 6, 9, 12, 18, and 24 months will be compared with pretreatment baselines. Patients with negative changes will be evaluated by the neurosurgeon and radiation oncologist to determine if the change is related to a local failure/complication or to progression of systemic disease. Kaplan-Meier estimates will be used.

Changes in symptoms assessed by neurological examinationBaseline to 24 months

The neurological exam includes (1) mental status (tested through history taking), (2) cranial nerves (Observation of eyes, face, voice, and coordination during history taking and as patient moves about the exam room. Look for extraneous movements), (3) motor system (visual inspection, tone, muscle strength and endurance, assigned score of 0-5 for each muscle, a score of 0 would mean no muscular contraction, and a score of 5 would mean movement against full resistance, normal strength), (4) reflexes, (5) sensory system (vibration in toes; pinprick in feet; (6) coordination (Truncal stability, fine finger movement, toe tapping, finger-nose-finger, heel-knee-shin), and (7) station and gait (Gait including arising from chair without hands, walking on toes, heels, and heel to toe). Kaplan-Meier estimates will be used.

Changes in quality of life (QOL) assessed by the MD Anderson Symptom Inventory Spine Tumor formBaseline to 24 months

Participants are asked to recall symptom severity and interference during the past 24 hours. Part I, The severity of the symptoms, including pain, fatigue, nausea, disturbed sleep, short of breath etc. Part II, How have the symptoms interfered with patient life, including mood, work, relations with other people etc. Part I, range 0-10. A score of 0 would mean the symptom is not present and a score of 10 means the symptom is as bad as you can imagine). Part II, range 0-10 (A score of 0 would mean the symptom did not interfere; A score of 10 means the symptom has interfered completely).

Changes in quality of life (QOL) assessed by SF-12 healthy survey (v2)Baseline to 24 months

Participants are asked to twelve questions that measure eight health domains to assess physical and mental health. Physical health-related domains include General Health (GH), Physical Functioning (PF), Role Physical (RP), and Body Pain (BP). Mental health-related scales include Vitality (VT), Social Functioning (SF), Role Emotional (RE), and Mental Health (MH). 3 and 5 point Likert scale is used in the survey. Two summary scores of the SF-12v2-physical and mental health-using the weighted means of the eight domains. Descriptive statistics will be used to summarize pain relief and quality of life at each follow-up visit, which will be the changes in scores from baseline to each assessment visit. Time to maximum pain relief will be the time from the day of thermal ablation until the lowest pain score for average pain after radiotherapy.
