Phase 1 - Optimization Phase:

Primary Objective: The primary objective of Phase 1 of this study is to determine the time point at which maximal Circulating Tumor Cell Burden (CTCB) occurs following standard vertebroplasty and Kyphoplasty procedures relative to baseline CTCB.

Phase 2 - Comparison Phase:

Primary Objective: The primary objective of Phase 2 of this study is to determine the change in CTCB from baseline to post-treatment as measured using the CellSearch™ Assay and to compare the average change between treatment groups with and without the use of the Cavity SpineWand.

Secondary Objectives:

* To determine the change in self-reported pain level from baseline to post-treatment as measured using the visual analogue scale (VAS) for spine pain and to compare the average change in pain level between treatment groups.
* To determine the change in pain status from baseline to post-treatment as measured using the Brief Pain Inventory (BPI) and to compare the average change in pain status between treatment groups.
* To determine the change from baseline to post-treatment in the M.D. Anderson Cancer Center Symptom Inventory (MDASI) and to compare the average change between treatment groups.
* To determine the change from baseline to post-treatment in time to walk a 50-foot distance and to compare the average change between treatment groups.

Kyphoplasty and Vertebroplasty:

Kyphoplasty and vertebroplasty are types of surgery that are used to treat broken bones in the back, which may have been caused by cancer. Both procedures involve injecting a mixture of medical cement into the broken bone(s) in the back. The cement is designed to harden and become a permanent part of the bone, supporting the bone like an "internal cast" that brings it back to its original shape. The amount of cement will vary from person to person, but it could be, for example, anywhere from a fraction of a teaspoon to a full teaspoon.

The main difference between the 2 procedures is that kyphoplasty involves the use of a small medical type of balloon, and vertebroplasty does not use balloons. Vertebroplasty also uses a slightly smaller needle to inject the cement.

The Study Device:

The Cavity SpineWand is a rod-shaped surgical tool that is designed to use a type of energy called plasma in order to destroy tissue at lower temperatures than other surgical methods. This may help to lessen damage to other nearby tissue.

In this study, the Cavity SpineWand will be used to remove tissue (soft tissue, bone tissue, or both, but this will vary from person to person), including all or part of the cancerous tumors in the area of the broken bone(s). This is designed to make extra room for the cement to be injected, either during the vertebroplasty procedure or the kyphoplasty procedure.

Screening Tests:

Before you can receive treatment in this study, you will have "screening tests" to help the doctor decide if you are eligible to take part in this study. If you have had some of these tests done recently, they may not need to be repeated. This will be up to your study doctor. The following tests may be performed:

* Your medical history will be recorded.
* You will have a magnetic resonance imaging (MRI) scan and a computed tomography (CT) scan. These scans will show pictures of your broken back bone(s) and the tumor. Your doctor will use these pictures to plan your surgery.

Women who are able to have children must have a negative urine pregnancy test.

Doctors currently do not fully understand whether kyphoplasty or vertebroplasty is better for treating broken bones in the back. For this reason, and because this study involves randomly assigning participants to receive one or the other of these procedures, all participants must be eligible for both procedures in order to take part in this study.

Treatment Groups:

If you are found to be eligible to take part in the study, you will be assigned to a treatment group. In each phase of the study, there is an equal chance of being assigned to any of the treatment groups.

If you are one of the first 20 patients enrolled in the study, you will be enrolled in Phase 1. You will be randomly assigned (as in the flip of a coin) to 1 of 2 groups. Phase 1 Group 1 will receive vertebroplasty, and Phase 1 Group 2 will receive kyphoplasty.

If you are one of the next 60 patients to be enrolled, you will be enrolled in Phase 2. You will be randomly assigned (as in the toss of dice) to 1 of 4 groups. Phase 2 Group 1 will receive vertebroplasty, and Phase 2 Group 2 will receive vertebroplasty with the Cavity SpineWand. Phase 2 Group 3 will receive kyphoplasty, and Phase 2 Group 4 will receive kyphoplasty with the Cavity SpineWand.

Study Tests/Procedures Before Surgery:

Within about 2-4 weeks before surgery, you will have tests and procedures performed. If you had some of these tests done recently, they may not need to be repeated. The following procedures may be performed:

* Your medical history will be recorded.
* You will have a physical exam, including measurement of vital signs (blood pressure, heart rate, temperature, and breathing rate).
* You will complete questionnaires that ask about the back pain and any drugs you are taking. In total, the questionnaires should take about 10-20 minutes to complete.
* You will be asked to walk 50 feet at your own pace while being timed to see how long it takes you. This is a routine test for comparing your walking function before and after surgery.

You will sign a separate consent form for surgery and the drugs used during surgery. These drugs include antibiotics to help lower the risk of infection, drugs to control pain, local anesthesia to make the area of your back where you are having surgery feel numb, and a sedative to make you feel relaxed and sleepy. The risks of these drugs will be explained to you in detail at that time.

Blood Test on the Day of Surgery:

On the day of surgery, blood (about 1 tablespoon) will be drawn. This blood will be compared with the blood that is drawn after surgery, to see when after surgery the most tumor cells are found in the blood.

Other Procedures Before Surgery:

As is standard for these types of surgery, special "bone" needles will be placed into the broken bone(s) in your back. X-rays will be used to guide the needles into a safe position. A biopsy of the tumor in your back bone will be collected to check the diagnosis of cancer. To collect a biopsy, a small amount of tumor tissue is withdrawn through the bone needle.

Surgical Procedures:

If you are in Phase 2 Group 2 or Phase 2 Group 4, the Cavity SpineWand will be used to remove a small amount of tissue immediately before the kyphoplasty or vertebroplasty procedure.

If you are in Phase 1 Group 2, Phase 2 Group 3, or Phase 2 Group 4, the kyphoplasty procedure will be done next. A small balloon will be placed into the area in your back where the tumor is located. Fluid will then be pumped through the tube in order to fill the balloon, which will create a hole in the back bone. After the balloon is deflated (closed) and removed, this hole will then be filled with cement. X-rays will be used to help place the cement safely.

If you are in Phase 1 Group 1, Phase 2 Group 1, or Phase 2 Group 2, the vertebroplasty procedure will be done next (instead of the kyphoplasty). Cement will be injected into the back bone. X-rays will be used to help place the cement safely.

No matter which treatment group you are in, if you have more than 1 broken back bone that needs treatment, the procedures described above will be repeated for a second broken bone, right after your first procedure. In other words, if you had vertebroplasty performed without the Cavity Spine Wand, that same procedure would be performed for the second bone. The procedure would only be repeated this 1 additional time, and not a third time.

No matter which treatment you receive, the entire procedure should take about 2-3 hours. If you need to have the procedure repeated on a second broken bone, this additional procedure should add about 45 minutes to the 2-3 hours that the first procedure alone would have taken.

Blood Testing for Phase 1 Participants:

Phase 1 participants will have blood (about 1 tablespoon each time) drawn at 8 different times points in order to measure the number of tumor cells. This blood will be drawn at 10, 30, and 60 minutes, and then at 2 hours, and between 6-8 hours, 10-18 hours, 20-28 hours, and 7 days after the surgery.

Blood Testing for Phase 2 Participants:

Phase 2 participants will have blood (about 1 tablespoon each time) drawn at 4 different time points after surgery. The first and second blood draw will occur before 36 hours has passed. The third blood draw will be about 36 hours after the surgery, and the fourth blood draw will be about 7 days after the surgery. This blood will be tested to measure the number of tumor cells.

Follow-Up Care:

You will be asked to return for follow-up visits at 7 days after your surgery and again at 4 weeks after your surgery. At these visits, the following tests and procedures will be performed:

* You will have a physical exam, including measurement of vital signs.
* You will complete the questionnaires that ask about the back pain and any drugs you are taking.
* You will be asked to walk a 50-foot distance, and your walk will be timed.
* At the Day 7 visit only, blood (about 1 tablespoon) will be drawn to measure the number of tumor cells.
* At the Week 4 visit only, you will be asked to complete a questionnaire that asks you to rate how satisfied you feel with the surgery. It should take about 10 minutes to complete.

At 3 months after your surgery, the study staff will call you at home to ask about the back pain and any drugs you may be taking.

Length of Study Participation:

After the Month 3 follow-up phone call, your active participation in this study will be over. If it is determined after your surgery that the tumor in your back was not cancerous, you would still return for the follow-up visits as is standard, but you would not need to have the Day 7 blood test to measure the number of tumor cells.

This is an investigational study. The vertebroplasty and kyphoplasty procedures are commercially available and FDA approved for the way they are being used in this study. The Cavity SpineWand is also commercially available and FDA approved for the way it is being used in this study. The research-specific part of this study is the blood testing to measure any increases in the number of cancer cells in the blood.

Up to 100 patients will take part in this study. All will be enrolled at M. D. Anderson.

Leanne M Ward, MD FRCPC

To determine the magnitude and rate of bone mass deficits following initiation of glucocorticoid therapy for the treatment of pediatric leukemia, rheumatic conditions and nephrotic syndrome, we propose a 6 year, prospective study in 12 academic, tertiary care centres across Canada.

The investigators hypothesize that glucocorticoid-treated children with leukemia, rheumatic conditions and nephrotic syndrome will fail to accrue bone mass at a normal rate, and that deficits in mineral accrual will occur in a glucocorticoid dose- and duration-dependent fashion. We also hypothesize that the fracture incidence will increase with concomitant reductions in bone mass.

Leukemia and Bone Morbidity Acute lymphoblastic leukemia (ALL) is the most common pediatric malignancy, with an overall survival rate now exceeding 70%. As such, there is an increasing population of survivors who are at risk for long-term sequelae of childhood leukemia, including osteoporosis. In Canada, there are approximately 250 new cases of childhood ALL diagnosed per year. All children in Canada undergoing therapy for the treatment of ALL in tertiary care pediatric hospitals will receive high dose glucocorticoids as per one of three ALL protocols (the Children's Cancer Group protocol, the Pediatric Oncology Group protocol, or the Dana Farber Cancer Institute Consortium protocol), depending upon the standard of care at a given institution. Musculoskeletal pain and gait abnormalities have been reported in one third of children with ALL at diagnosis, a sub-set of whom also demonstrate fractures. Radiographs of painful regions show metaphyseal lucencies, sclerotic lesions and sites of periosteal reaction in many of the patients with bone pain at presentation. Lumbar spine areal bone mineral density (BMD) is reduced at diagnosis, while total body and volumetric BMD are within the normal range. Several groups have reported significant loss of bone mass during therapy for ALL, while studies of bone mass restitution following chemotherapy have led to inconsistent results. The most rapid reductions in bone mass have occurred in the first 6-8 months of therapy, similar to the observed glucocorticoid effect on bone in adults. Fractures have been present in as many as 13% of children at diagnosis, rising to 39% during chemotherapy. In addition to glucocorticoids, a number of other mechanisms have been proposed for the skeletal morbidity in ALL, including infiltration of bone by leukemic cells, paraneoplastic factors, other medications, physical inactivity, cranial irradiation, inadequate nutrition and disordered mineral metabolism.

Rheumatic Conditions and Bone Morbidity Rheumatic diseases of childhood, including juvenile rheumatoid arthritis, systemic lupus erythematosis and juvenile dermatomyositis, are well-known to be associated with compromised skeletal health. Of these, juvenile rheumatoid arthritis has been evaluated the most extensively. Significant reductions in bone mass have been documented in a number of studies of pediatric patients with chronic rheumatic disease, and atraumatic fractures have been noted at an early age. Active arthritis may affect bone metabolism in areas adjacent to affected joints ("periarticular osteopenia"), and at more distant sites including the radius, spine, and femoral neck. In a recent study of pediatric patients with reductions in bone mass secondary to chronic rheumatic disease, 8/38 (21%) of patients had fragility fractures, primarily of the vertebrae. Similar to other osteoporotic conditions due to chronic illness, the pathogenesis of the bone morbidity in these cases is multi-factorial, with disease activity, muscle disease, physical inactivity, nutritional status and medical therapy playing significant roles. However, as in leukemia, glucocorticoid use has emerged as one of the strongest determinants of skeletal morbidity during treatment for juvenile rheumatoid arthritis and systemic lupus erythematosis. The role of glucocorticoids in bone morbidity associated with pediatric rheumatic diseases such as juvenile dermatomyositis and vasculitides has not been determined.

Nephrotic Syndrome and Bone Morbidity Childhood nephrotic syndrome is an idiopathic disorder characterized by proteinuria, hypoproteinemia, edema and hyperlipidemia. The incidence of the syndrome varies between 1:15,000 to 1:50,000. Following the introduction of glucocorticoid therapy in the 1970's, the mortality from nephrotic syndrome decreased dramatically over the ensuing 15 years, from 35 to 3 per cent. The vast majority of patients with nephrotic syndrome have steroid-responsive disease. In Canada, the standard of care for children with their first episode of nephrotic syndrome is high-dose glucocorticoid therapy for 6 weeks, followed by gradual tapering over the next three to seven months. Only one-third of patients will enter into permanent remission with this regime, while another third will require pulse steroid therapy for up to six weeks' duration at infrequent intervals throughout the growing years. The final third of patients will either require frequent courses of pulse glucocorticoid therapy or chronic steroid administration in order to achieve remission. Children with nephrotic syndrome are typically well-nourished, fully ambulatory, and otherwise well between episodes. Furthermore, their treatment regime is more likely to be characterized by glucocorticoid therapy alone, compared to the polytherapy that is required for the treatment of leukemia and rheumatic conditions. As such, the greater homogeneity of the nephrotic syndrome population allows for a more "pure" assessment of glucocorticoid effect on pediatric bone. Small studies have demonstrated reductions in bone mass by dual energy x-ray absorptiometry (DXA) and an increase in biochemical markers of bone resorption among young, glucocorticoid-treated patients with nephrotic syndrome. Tenbrock et al. recently showed by peripheral quantitative computed tomography that 16 children with nephrotic syndrome, all previously treated with glucocorticoids, had reductions in cortical area at the distal radius, which correlated with reductions in grip strength. The fracture rate among children with nephrotic syndrome is presently unknown. Among adults with nephrotic syndrome, high-dose glucocorticoid administration led to rapid bone loss in the first few months of therapy, raising the question whether preventive therapy should be initiated in such adults after three months of glucocorticoid use, if measures of bone mass have fallen significantly below baseline.

We will determine the magnitude and rate of total body, hip and lumbar spine bone mass deficits following initiation of glucocorticoid therapy, in relation to glucocorticoid dose and duration, among children with leukemia, rheumatic conditions and nephrotic syndrome. The longitudinal pattern of deficits (or gains) in bone mass will be determined for each disease state by plotting bone mass measurements taken at 6 month intervals throughout the study, with an additional 3 month measurement being recorded for patients with nephrotic syndrome.

To identify whether a glucocorticoid threshold dose exists for each of the three disease categories, above which significant deficits in bone mass are likely to occur.

To assess the frequency of atraumatic fractures in relation to glucocorticoid dose and duration for each of the three chronic illnesses.

To determine the fracture risk associated with a given reduction in bone mass from baseline, for each of the three chronic diseases.

To determine the magnitude of bone mass restitution when glucocorticoid therapy is withdrawn, and to evaluate whether recovery is age- and/or pubertal stage-dependent.

To investigate the relationship between handedness and lateralization of bone density.
