Targeted radiofrequency ablation

Targeted radiofrequency ablation is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Targeted radiofrequency ablation rather than just read about it. In short: Targeted radiofrequency ablation (also written t-RFA) is a minimally invasive procedure to treat severe pain and discomfort caused from metastatic tumors in the vertebral body of the spine. This procedure uses radiofrequency energy to target and ablate a specific spinal tumor, causing it shrink and reduce the pressure on the surrounding nerves and tissues.

Key takeaways

Learn the definition first, then one example that makes the definition concrete.
Connect Targeted radiofrequency ablation to a quantity you can measure, compute or draw — that is where exam questions come from.

Reference excerpt

Targeted radiofrequency ablation (also written t-RFA) is a minimally invasive procedure to treat severe pain and discomfort caused from metastatic tumors in the vertebral body of the spine. This procedure uses radiofrequency energy to target and ablate a specific spinal tumor, causing it shrink and reduce the pressure on the surrounding nerves and tissues. The procedure minimizes damage to the vertebrae and surrounding tissues. It is used as a palliative therapy rather with the intention of treating the cancer itself.

History Targeted radiofrequency ablation was first developed by DFINE, Inc., a medical device company based in San Jose, California. Its product, the STAR Tumor Ablation System received 510(k) clearance from the United States Food and Drug Administration in August 2010. It is cleared for sale in the US and CE marked in Europe. The procedure was first performed at the James Graham Brown Cancer Center located at the University of Louisville Hospital in March 2012.

Procedure Targeted radiofrequency ablation is not a treatment for cancer, but is used for pain management. It is usually an outpatient procedure using local anesthesia through a small incision. t-RFA uses a small steerable device that is placed into the vertebra, navigated by a physician to the targeted tumor. The physician can then deliver the energy to heat and destroy metastatic spinal tumor cells. The procedure minimizes damage to surrounding tissue and vital structures and has been shown to provide pain relief in a single treatment.

Efficacy A 2013 study published in the Journal of NeuroInterventional Surgery showed that t-RFA was an effective method of pain relief with low morbidity. Patients in the study also reduced their requirements of pain relieving drugs after receiving the treatment and also regained the ability to perform movements that they were previously restricted from due to the pain. Another 2013 study published in the Journal of Vascular and Interventional Radiology showed that patients receiving the procedure had reduced pain where traditional treatment methods were unsuccessful. A third study published in 2013 showed that t-RFA allowed treatment of lesions that were not controlled by either radiation therapy or systemic therapy. A 2014 study published in the Journal of Vascular and Interventional Radiology showed a decrease in tumor volume and metabolic activity in all 34 patients who received the treatment. The ability to provide localized t-RFA of metastatic lesions of the spine may provide rapid and lasting pain relief, enabling patients to restore their quality of life with minimal, if any, delay in systemic, curative therapy of their primary cancer. As compared to radiation, which often requires multiple visits, the procedure provides patients with pain relief from metastatic spinal tumors in a single, minimally invasive treatment. The STAR System potentially minimizes additional VCFs due to radiation related bone fragility as well as the side effects of radiation. This procedure can be performed in addition to chemotherapy, radiation therapy or other therapies that are ongoing to treat the primary cancer often allowing the patient the tolerance to continue their therapy.

Worked examples

Example 1 — a first encounter with Targeted radiofrequency ablation

Start with the simplest possible case. Write down what Targeted radiofrequency ablation claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Targeted radiofrequency ablation before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Targeted radiofrequency ablation ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Targeted radiofrequency ablation

In research: Targeted radiofrequency ablation appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Targeted radiofrequency ablation in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Targeted radiofrequency ablation is common in secondary-school and first-year university syllabi. It links to neighbouring topics Medical procedures, so understanding it makes those chapters shorter.
In everyday life: Look for Targeted radiofrequency ablation outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
