Worked calculation
The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.
| Performance status | 0 — Fully active |
|---|
→ECOG PS0
- ≈ Karnofsky：~90–100
- Note：Generally compatible with systemic anticancer therapy.
| Performance status | 5 — Dead |
|---|
→ECOG PS5
- ≈ Karnofsky：0
- Note：PS ≥ 3 often precludes intensive systemic therapy/trial eligibility.

- Inputs: Performance status 0 — Fully active → Result: ECOG PS 0（≈ Karnofsky: ~90–100, Note: Generally compatible with systemic anticancer therapy.） Inputs: Performance status 5 — Dead → Result: ECOG PS 5（≈ Karnofsky: 0, Note: PS ≥ 3 often precludes intensive systemic therapy/trial eligibility.）
