Prognostic parameters and spinal metastases: a research study

Area of Science:

• Oncology
• Neurosurgery
• Spinal Surgery

Background:

• Spinal epidural neoplastic metastasis (SENM) presents a significant challenge, particularly when the primary tumor is unknown.
• Accurate prognostic assessment is crucial for determining appropriate treatment strategies, balancing surgical intervention with palliative care.

Purpose of the Study:

• To identify pre-operative prognostic factors influencing survival in patients diagnosed with SENM of unknown primary origin.
• To provide data that can aid in surgical decision-making for this patient cohort.

Main Methods:

• Retrospective chart review of 52 patients who underwent surgery for SENM between 1997 and 2011.
• Kaplan-Meier survival analysis and Log-Rank tests were employed to assess survival outcomes.
• Prognostic parameters evaluated included pre-operative walking ability, Karnofsky Performance Score, and tumor involvement of the thecal sac.

Main Results:

• The median post-operative survival was 70 days, with 73.07% of patients dying within 6 months.
• Common primary tumor types included lung cancer, prostate cancer, myeloma, and lymphoma (61.53%).
• Pre-operative walking incapacity, special care dependency, and thecal sac contact with metastases were identified as potential prognostic indicators.

Conclusions:

• Pre-operative walking incapacity, dependency on special care, and tumor contact with the thecal sac are significant factors for predicting survival in SENM patients with unknown primary tumors.
• A post-operative survival of 2-3 months may justify surgical treatment, guiding the balance between aggressive intervention and palliative care.
