When to Use
When to Use
Counseling patients with systemic cancer suffering from spinal cord compression.
Evaluating if a massive corpectomy / en-bloc resection is mathematically justifiable.

Literature
Development
Yasuaki Tokuhashi developed this system in 1990 and revised it in 2005. It fundamentally changed spine oncology from "treat everyone" to a survival-driven algorithm. He found that primary tumor histology is the absolute dictator of survival (giving it up to 5 points), overshadowing even the extent of the spinal cord palsy.
Section 3
Pearls/Pitfalls
Surgery Thresholds
If the score is ≤ 8, life expectancy is less than 6 months. Subjecting this patient to a grueling 10-hour spinal fusion deprives them of the little time they have left. Treatment should be purely palliative (steroids/radiation). Aggressive "cure" surgery is only indicated for scores ≥ 12 (typically solitary lesions of favorable histology like breast or prostate).
