The Tokuhashi Score was published in 1990 and is used to assess prognosis in patients with spinal metastases1.
| General condition (KPS) | Points |
|---|---|
| Poor (KPS 10% - 40%) | 0 |
| Fair (KPS 50% - 70%) | 1 |
| Good (KPS 80%-100%) | 2 |
| Number of extraspinal bone metastasis foci | Points |
| ≥ 3 | 0 |
| 1 - 2 | 1 |
| 0 | 2 |
| Number of vertebral body metastases | Points |
| ≥ 3 | 0 |
| 2 | 1 |
| 1 | 2 |
| Metastases in major internal organs | Points |
| Not removable | 0 |
| Removable | 1 |
| No metastases | 2 |
| Primary tumor site | Points |
| Stomach, lung | 0 |
| Kidney, liver, uterus, other, or not identified | 1 |
| Thyroid, prostate, breast, rectum | 2 |
| Paralysis | Points |
| Complete (Frankel A,B) | 0 |
| Incomplete (Frankel C,D) | 1 |
| None (Frankel E) | 2 |
The calculated Tokuhashi Score can be interpreted as follows2:
| Points | Average survival |
|---|---|
| 0-5 | ≤ 3 months. Conservative, palliative treatment |
| 6-8 | ≤ 12 months |
| 9-12 | ≥ 12 months. Surgical treatment |
