Overview
Diagnosis of Bone Metastasis
Bone metastasis is diagnosed using imaging tests and biopsy.
Imaging tests can identify areas of bone affected by cancer:
-
X-ray: Detects changes in bone structure.
-
Bone scan (bone scintigraphy): Highlights areas of abnormal bone activity.
-
CT scan: Provides detailed cross-sectional images of bones.
-
MRI scan: Offers high-resolution images of bone and surrounding soft tissues.
-
PET scan: Detects active cancer cells in bones.
Biopsy confirms the presence of cancer cells:
-
A tissue sample is removed from the bone and examined in a lab.
Treatment of Bone Metastasis
Treatment depends on the extent of metastasis, symptoms, and overall health. Approaches may include medicines, radiation therapy, surgery, and supportive therapies.
Bone-building medicines:
-
Strengthen bones and reduce pain caused by metastasis.
-
Administered via intravenous infusion or shots; pills may be less effective.
-
Side effects include kidney issues, short-term bone pain, and risk of jawbone osteonecrosis.
Radiopharmaceutical medicines:
-
Low-dose radioactive medicines travel to cancer in the bones and relieve pain.
-
Side effects may include low blood cell counts due to bone marrow effects.
Chemotherapy:
-
Treats cancer that has spread to multiple bones using strong medications.
Hormone therapy:
-
Blocks hormones that some cancers (breast or prostate) need to grow.
-
Can involve medications to reduce hormone levels or surgery to remove hormone-producing organs.
Pain medicines:
-
Over-the-counter or prescription medications to manage pain.
-
A pain specialist can help optimize relief.
Targeted therapy:
-
Uses drugs that attack specific chemical pathways in cancer cells.
-
Effectiveness depends on testing cancer cells for specific targets.
Radiation therapy:
-
Uses X-rays, protons, or other energy beams to treat one or a few bone metastases.
-
Helps control pain and tumor growth but does not rebuild bone.
Stereotactic body radiotherapy:
-
Highly precise, intense radiation aimed from multiple angles.
-
Often used for spinal metastases to protect surrounding tissues.
Surgery:
-
Orthopedic fixation: Stabilizes bones at risk of fracture using metal plates, screws, or rods.
-
Bone cement injection: Stabilizes broken bones that can’t be fixed with metal.
-
Repair of broken bones: Includes metal implants or joint replacements.
Ablation therapy:
-
Applies heat (radiofrequency ablation) or cold (cryoablation) directly to cancer cells.
-
Can relieve pain and control local tumor growth.
-
Side effects may include nerve damage or increased risk of fracture.
Clinical trials:
-
Offer access to new treatments or new uses of existing therapies.
-
Side effects and success rates may vary; discuss options with your healthcare professional.
Physical therapy:
-
Helps improve strength, mobility, and balance.
-
May include assistive devices like crutches, canes, or braces.
-
Exercises can maintain strength and reduce pain.
