Metastatic spinal tumors require prompt diagnosis and treatment. Surgery is indicated for pain, spinal cord compression, or fracture risk, with anterior approaches often preferred for decompression.

Area of Science:

  • Oncology
  • Neurosurgery
  • Orthopedic Surgery

Background:

  • Metastatic spinal tumors are the most common malignant spine lesions.
  • Early diagnosis and primary tumor identification are critical for effective treatment.
  • Patient outcomes depend on primary cancer type, lesion burden, and spinal cord compression severity.

Purpose of the Study:

  • To review the diagnosis and management of metastatic spinal tumors.
  • To outline indications and surgical approaches for spinal metastases.
  • To discuss adjuvant therapies and emerging procedures.

Main Methods:

  • Review of current literature on metastatic spinal tumors.
  • Discussion of diagnostic criteria and prognostic factors.
  • Analysis of treatment modalities including chemotherapy, radiotherapy, and surgery.

Main Results:

  • Initial management involves chemotherapy, radiotherapy, and orthoses.
  • Surgical candidates generally have an expected survival exceeding 12 weeks.
  • Indications for surgery include intractable pain, spinal cord compression, and impending fractures.
  • Anterior surgical approaches are favored for spinal cord decompression.
  • Posterior approaches may require longer fusions.
  • Instrumentation and polymethylmethacrylate augmentation are key for stable fixation.
  • Preoperative embolization is recommended for highly vascular tumors (e.g., renal cell carcinoma).
  • Vertebroplasty offers a percutaneous option for selected cases of intractable pain.

Conclusions:

  • Multidisciplinary management is essential for metastatic spinal tumors.
  • Surgical intervention, particularly anterior decompression, plays a vital role in selected patients.
  • Advanced techniques like vertebroplasty offer new therapeutic avenues.
