Revised Tokuhashi Scoring System

The revised Tokuhashi score predicts survival in patients with spinal metastases to guide the choice between conservative treatment, palliative surgery, or excisional surgery.

Tokuhashi Score Calculator — Spine Metastases Surgical Prognosis

Clinical Context & Background

The Revised Tokuhashi Score (2005) is a prognostic scoring system for patients with spinal metastases. It assesses general condition, extraspinal bone metastases, number of vertebral metastases, metastases to internal organs, primary site, and spinal cord palsy. The total score helps decide between excisional surgery, palliative surgery, or non-surgical management.

When To Use

  • Use Tokuhashi Score Calculator — Spine Metastases Surgical Prognosis when calculate the revised Tokuhashi score for spinal metastases prognosis. Evaluate 6 prognostic parameters to guide surgical decision-making for vertebral metastatic disease.
  • Confirm that the patient, diagnosis, disease phase, and available inputs match the cited model before calculation.

How To Interpret

  • Interpret the displayed result using the calculator-specific formula and reference table, spanning 0 - 8 through 12 - 15.
  • A boundary result should prompt input verification and clinical review rather than false precision.

What To Do Next

  • Combine the score with neurologic examination, mechanical pain, imaging, oncologic prognosis, radiosensitivity, surgical options, and patient goals.
  • Document the inputs, result, timing, and clinical context so the assessment can be reproduced.

Limitations

  • Fracture, spinal-instability, survival, and surgical-selection scores measure different domains and cannot substitute for urgent specialist assessment.
  • The result supports clinician judgment and does not independently determine treatment.

Validated Population

patients undergoing skeletal metastasis stability, fracture-risk, survival, or operative assessment

How to apply this result

For a representative case, verify General Condition, Number of Extraspinal Bone Metastases, Number of Metastases in Vertebral Body, calculate the result, and confirm that its classification matches the highlighted reference band before continuing the disease-specific pathway.
