Spinal Metastasis

Spinal metastasis means a cancer from elsewhere in the body has spread to the bones of the spine. It's a common complication of advanced cancer, and it usually causes pain rather than an emergency. Most people are treated well with pain control, radiotherapy and medicines, and only a small number ever need surgery.

What Is Spinal Metastasis?

Spinal metastasis happens when cancer cells break away from a tumour somewhere else in the body and travel through the bloodstream to settle in the spine. Doctors also call this metastatic spine cancer, secondary spine cancer, or bone metastases of the spine. It's a different problem from a tumour that starts in the spine itself, which is much rarer.

The cancer usually lodges in the vertebrae, the small bones that stack up to form the spine, most often in the mid-back (thoracic spine) or lower back (lumbar spine). Less often, the growth presses on the spinal cord or the nerves running through it.

Which Cancers Spread to the Spine, and Who Gets It?

Almost any cancer can spread to the spine, but some do it more than others.

Estimates vary, but spinal metastasis can affect anywhere from about 1 in 20 to nearly 1 in 3 people living with cancer. If you've been treated for one of the cancers above, your oncologist may already be watching for this.

How Serious Is Spinal Metastasis?

For most people, it causes pain that responds well to medicines, radiotherapy, or a combination of both. It's a sign that the cancer has spread, and treatment focuses on controlling pain, protecting the spine and keeping your quality of life as good as possible, rather than on curing the cancer itself.

In a small number of people, the growth presses on the spinal cord or the nerves. This is called spinal cord compression, and it needs prompt attention. The next section covers what to watch for.

What Are the Symptoms of Spinal Metastasis?

The most common symptom is back or neck pain. It's often described as:

• A constant, dull ache that's worse at night or when lying flat
• Pain that gets worse with coughing, sneezing or straining
• Pain that doesn't ease with rest, unlike ordinary mechanical back pain

Other symptoms can include a change in the shape or curve of the spine, numbness, tingling or weakness in the arms or legs, trouble with balance or walking, or difficulty controlling the bladder or bowels. Many people with spinal metastasis have no symptoms at all, and it's picked up on a scan done for another reason.

How Is Spinal Metastasis Diagnosed?

Your doctor will start with an examination, checking for pain patterns, weakness or balance problems, and will ask about any current or past cancer. Tests may include:

• MRI scan – the best way to see the spine, spinal cord and nerves in detail
• CT scan – useful for looking closely at the bone
• X-rays – can show changes in the shape or structure of the vertebrae
• Bone scan – can pick up areas of abnormal bone activity
• Blood tests – certain markers can rise when cancer affects bone
• Biopsy – a small tissue sample, taken with a needle, to confirm the type of cancer if this isn't already known

Will Spinal Metastasis Get Worse Over Time?

Left untreated, spinal metastasis can grow and weaken the affected vertebra, raising the risk of a fracture or of pressure on the spinal cord. With treatment, growth can often be slowed and symptoms controlled well. Your outlook depends on the type of cancer involved, how it responds to treatment, and your overall health. Your oncologist is best placed to talk you through what to expect.

What Is the Outlook for Someone With Spinal Metastasis?

Outlook differs a lot from person to person, so no single number fits everyone. Treatments have improved, and many people now live longer with good pain control and keep walking through their treatment. Three things matter most:

• Walking ability when treatment starts. This is the strongest sign of how well you will do afterwards.
• The type of cancer. Outlook is generally better with breast cancer, prostate cancer and blood cancers such as myeloma and lymphoma. It is harder with lung cancer and with breast cancer that no longer responds to hormone treatment.
• How far the cancer has spread. Spread to organs such as the liver or lungs makes things harder than cancer that is mostly in the bones.

Doctors also use scoring tools, built from the records of thousands of patients, to estimate how someone is likely to do over the next few months. These help your team decide whether an operation is likely to help you. They are a guide, not a verdict. Your oncologist and spine surgeon can tell you what this means in your own case.

Will I Walk Again if My Nerves Are Affected?

The good news is that most people who are walking when treatment starts keep walking. The table shows what tends to happen, based on how the legs are working before treatment.

Bladder control can improve too. Of people who need a catheter because of nerve pressure, about 2 to 4 in 10 manage without it after treatment.

Why Does Acting Early Matter?

What you can do before treatment decides a lot of what you keep afterwards. The better your legs are working when treatment starts, the better they tend to work afterwards.

Nerve problems from spinal metastasis can get worse quickly, sometimes within days. Treatment started within 48 hours of losing the ability to walk gives the best chance of getting it back. The longer it waits after that, the less likely recovery becomes.

So if you have had cancer and notice new back pain, new weakness or numbness, do not wait to see if it settles. Call your oncologist or spine surgeon the same day.

What Non-Surgical Treatments Are Available?

Most people with spinal metastasis are treated without surgery.

• Pain medicines – from simple painkillers to stronger prescription options, tailored to your needs
• Bone-strengthening medicines – can reduce the risk of fracture and help with pain
• Radiotherapy – a common and effective way to shrink the tumour and relieve pain; stereotactic radiosurgery is a more precise, focused form of this
• Cancer-specific treatment – chemotherapy, hormone therapy or targeted therapy aimed at the original cancer, arranged together with your oncologist
• Bracing – a supportive brace can help with comfort and stability in some cases
• Minimally invasive vertebroplasty or kyphoplasty – for a fractured vertebra, bone cement is used to stabilise it and ease pain, without open surgery

When Is Surgery Needed for Spinal Metastasis?

Surgery isn't the first option for most people. It's usually considered when there's a fracture, or the spine is at high risk of one, when a tumour is pressing on the spinal cord or nerves and causing weakness, when pain isn't controlled by other treatments, or when the spine has become unstable.

If you're unsure whether your current treatment plan is right for you, or would simply like a fresh pair of eyes on your scans, you're welcome to 🔍Second Opinion on Your MRI.

What Does Spine Surgery for Metastasis Involve?

When the spinal cord or nerves need decompressing, this is usually done through minimally invasive techniques with percutaneous screw stabilisation, smaller incisions and less muscle disruption than open surgery, which supports a quicker recovery. The right approach depends on where the tumour is, how much it has affected the bone, and your general fitness for surgery.

What Is Recovery Like?

Radiotherapy and medical treatment usually don't need a hospital stay. Recovery after surgery varies a great deal from person to person, and depends a lot on how you were doing before the operation, your strength, mobility and general condition going in. Your team will guide you on movement, bracing if needed, pain management, physiotherapy and follow-up scans.

Can Spinal Metastasis Be Prevented?

There's no guaranteed way to prevent cancer from spreading to the spine. If you have a cancer that's known to spread to bone, staying on schedule with your oncology follow-up helps catch any spread early, often before it causes symptoms.

Questions to Ask Your Doctor

• What part of my spine is affected, and how much?
• Is my spine stable, or at risk of a fracture?
• What are my treatment options, and what does each involve?
• Do I need surgery, or can this be managed without it?
• What symptoms should prompt me to seek urgent care?

Treatments We Offer for This

Pain management, radiotherapy coordination with your oncology team, bracing, minimally invasive vertebroplasty and kyphoplasty, and minimally invasive decompression with percutaneous stabilisation when surgery is needed.
