Expand your range of treatment options

While any patient with focalized pain from a metastatic spinal tumor may be a candidate for t-RFA, several specific patient groups will likely benefit most from the procedure.

These include patients…

  • with radio-resistant tumors.
  • with recurrent pain after radiation therapy.
  • with posterior vertebral body metastatic tumors.
  • who have reached their maximum radiation dose limit.
  • with localized pain and symptoms that are preventing palliative radiation.
  • who cannot undergo other palliative treatments due to current systemic treatments.
  • in which myelosuppression is of concern.

“The spine tumor ablation procedure is particulary helpful for those patients who have a type of tumor that is radiation therapy resistant. In these patients the local control for a tumor in the spine and the pain relief we can offer can be significant.”

A Known Solution

Rapid pain relief + localized tumor destruction

For localized bone pain, such as that associated with painful metastatic spinal lesions, the National Comprehensive Cancer Network (NCCN) Clinical Practice Guidelines indicate that radiofrequency ablation should be a considered treatment option.*

Fast & Durable

Oncologists and cancer care team members recognize the fast and durable pain relief patients achieve with minimally invasive targeted radiofrequency ablation (t-RFA).

Single Treatment

Using the STAR Tumor Ablation System, t-RFA delivers meaningful pain relief and localized tumor destruction in a single treatment, often in an outpatient setting.


With the STAR System, physicians have the control to create site-specific ablation zones and monitor real-time ablation zone development within the vertebral body.


Compatible with systemic therapies, t-RFA expands the range of treatment options for patients with painful spinal tumors.

Meaningful Clinical Outcomes

Clinical data show that rapid and lasting pain relief from metastatic spinal tumors is a reality for patients who receive t-RFA using the STAR System. This multicenter retrospective study included 128 treated lesions in 92 patients, many of whom had failed radiation therapy. Pain was decreased by 77% and 54% of the patients were able to reduce pain medication usage after t-RFA.*


“I’m so glad I had the STAR procedure. I can go watch my grandkids play soccer… I look forward to life again. I have hope.”

A desirable combination of therapeutic advantages for your patients

Focus on treatment of primary cancer

By quickly addressing painful metastatic disease, targeted Radiofrequency Ablation(t-RFA) allows patients to concentrate on primary cancer treatments.

Rapid Pain Relief

The STAR System enables a single, minimally invasive procedure that can provide rapid, durable pain relief and localized tumor destruction.

Treatment Compatibility

t-RFA is non-toxic, thereby allowing patients to continue their current systemic treatment uninterrupted.

Increased Options

The STAR System offers a treatment path for patients with limited options, including those with radio-resistant tumors or who have reached their radiation dose limits.

Targeted therapy for fast, local control

The SpineSTAR Ablation Instrument is uniquely designed specifically for use in the complex anatomy of the spine. This small steerable device is inserted into the vertebra to deliver targeted RF energy to the tumor. RF energy heats and destroys metastatic tumor cells, while temperature sensors within the SpineSTAR continuously monitors the ablation zone progress to minimize patient risk. Additionally, the instrument is created with a coaxial lumen to facilitate biopsy or injection of cement if indicated without removing the cannula.

“There are a number of features of the [SpineSTAR] device that I really like; the thermocouples on the tip allow me to actually measure the zone of ablation. The articulating tip allows and facilitates reaching to areas in the vertebrae that are not possible with a straight fixed device.”

Indications for Use

The STAR™ Tumor Ablation System is indicated for palliative treatment in spinal procedures by ablation of metastatic malignant lesions in a vertebral body.


Risks and Contraindications

As with most surgical procedures, there are risks associated with the STAR procedure, including serious complications. For complete information regarding risks, contraindications, warnings, and precautions, please review the systems’ Instruction for Use. For more information regarding adverse events, please see our Indications Page.
