Metastatic spinal tumors

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.
