What is bone metastasis RFA?
Cancer that started somewhere else in the body — most often breast, prostate, lung, kidney, or thyroid — can spread to bones. When it does, it can cause deep, aching, hard-to-control pain. Most patients are first treated with pain medications and a course of palliative radiation therapy from a radiation oncologist. Those work for many people, but not everyone.1
RFA gives you a different option. Using live X-ray or CT imaging, a board-certified interventional radiologist guides a thin probe — about the diameter of a pencil lead — through the skin and into the painful spot in the bone. Once the probe is in the right place, it delivers heat energy for several minutes. The heat does two things at once: it kills the tumor tissue inside the lesion, and it destroys the tiny nerves in the bone that have been carrying the pain signal. There is no large incision, no major surgery, and most patients go home the same day.
How RFA fits with the rest of your cancer care
RFA is a pain treatment, not a replacement for the cancer treatments you may already be on. Patients typically continue their chemotherapy, immunotherapy, hormone therapy, or whatever their medical oncologist has them on. RFA is added to the plan to control pain in one or two specific spots that have not responded to other approaches — or where you and your team simply want a faster answer.
Cómo funciona el procedimiento
The procedure is done in a hospital interventional suite under sedation or general anesthesia, so you’ll be asleep or deeply relaxed and won’t feel anything during the ablation. Using continuous imaging, the probe is positioned precisely inside the lesion. Energy is delivered for several minutes — long enough to bring the inside of the lesion to a temperature that destroys both tumor cells and pain-carrying nerves. The whole procedure usually takes between 60 and 120 minutes.
If the bone is structurally weakened by tumor and your team is worried about it breaking, RFA can be combined with cementoplasty in the same session. Cementoplasty is the injection of medical bone cement (the same kind used in joint replacement and vertebroplasty) into the lesion to reinforce the bone. The combination treats the pain and helps prevent fracture at the same time.2
What to expect
Most patients describe RFA as far easier to tolerate than they expected. Recovery is short, and pain relief tends to build over the weeks that follow.
Before the procedure
We review your imaging — CT, MRI, or PET/CT — together with your oncology team. The goal is to confirm that one or two specific lesions are causing most of your pain and that RFA is the right next step. Your medical oncologist, radiation oncologist, and palliative care team are part of this conversation.
The day of the procedure
You arrive in the morning and check in to the interventional suite. Sedation or general anesthesia is given. The probe is guided into the lesion under live imaging, and energy is delivered. If your bone needs reinforcement, medical cement is injected through the same access. The whole appointment usually takes a few hours from check-in to discharge.
Going home
Most patients go home the same day. You’ll need someone to drive you. You may have some soreness at the access site for a few days, which is usually well-controlled with the pain medications you’re already on or a short course of an anti-inflammatory.
How quickly the pain improves
Many patients notice improvement in the first 1 to 4 weeks. The largest randomized clinical trials of RFA for painful bone metastases (OPuS One and MOTION) showed that average pain scores dropped by roughly half, with the most pronounced relief between 4 and 12 weeks after the procedure.3
¿Quién es un buen candidato?
RFA is most useful when the source of the pain is one or two focal lesions, rather than diffuse pain throughout many bones. You may be a good candidate if any of the following apply:
- You have one or two specific painful spots in bone — most often the spine, pelvis, sacrum, ribs, or a long bone like the femur or humerus
- You have already had palliative radiation therapy and the pain is still there, or it has come back in the same spot
- The painful area is in a previously irradiated field where your radiation oncology team cannot safely give more radiation
- You want a faster option — radiation can take weeks to give its full effect, while RFA tends to work within a few weeks of a single procedure
- The lesion weakens the bone enough to risk a fracture, and combining RFA with cementoplasty makes sense
RFA is not the right choice for everyone. Diffuse pain throughout the skeleton, lesions in spots where heat could damage nearby spinal cord or major nerves, or active infection in the area are all reasons we may recommend a different approach. Those decisions are always made together with your medical oncology, radiation oncology, orthopedic oncology, and pain management teams.4
Who performs bone metastasis RFA
Bone metastasis RFA is performed by interventional radiologists. The procedure depends on continuous live imaging, precise probe placement, and careful temperature monitoring — all core skills of the specialty. At Florida Interventional Specialists, every RFA case is delivered in close coordination with the medical oncology, radiation oncology, palliative care, pain management, and orthopedic oncology teams across Tampa Bay.
Preguntas frecuentes
What is bone metastasis RFA?
It’s an image-guided procedure that uses a thin probe to deliver heat directly to a painful cancer lesion in the bone. The heat destroys tumor tissue and the small nerves carrying the pain signal. Most patients go home the same day.
How is RFA different from radiation therapy?
Both can relieve cancer pain in the bones, and they’re often used together. Radiation is given in one or several sessions and works gradually. RFA is a single, same-day procedure that targets one or two specific spots and tends to work faster. RFA is often used when radiation has already been given, when radiation has not provided enough relief, or when you can’t wait for radiation to take effect.
Will I be awake during the procedure?
No. The procedure is performed under sedation or general anesthesia. You will not feel the probe being placed or the energy being delivered.
How quickly will my pain improve?
Many patients notice improvement in the first 1 to 4 weeks. The largest published clinical trials show that average pain scores drop substantially by 4 to 12 weeks.
Can RFA prevent a bone from breaking?
When the bone is structurally weakened by tumor, RFA is often combined with cementoplasty — injection of medical bone cement — in the same session to reinforce the bone and reduce fracture risk while also relieving pain.
Is RFA a treatment for the cancer itself?
RFA is primarily a pain treatment for one or two specific spots. It is not a substitute for the systemic cancer therapy that your medical oncologist manages. Most patients receive RFA alongside their chemotherapy, immunotherapy, hormone therapy, or radiation as part of a coordinated cancer care plan.
