Revised Tokuhashi Score
Estimates survival in spinal metastases to guide surgery.
When to use
Adults with spinal metastases at preoperative assessment.
Pearls and pitfalls
- The score adds general condition, bone, vertebral and visceral metastases, primary tumor and palsy.
- The primary tumor is the heaviest item, worth 0 to 5 points.
- A score of 0 to 8 suggests survival under 6 months; 12 to 15 suggests 1 year or more.
- The score predates current targeted therapies and should be interpreted with the oncologic context.
