Performance Status ECOG / Karnofsky — free guideline decision tool
This tool maps ECOG (0–5) to Karnofsky (0–100) performance status and flags the performance threshold for systemic anticancer therapy.
Open guideline tool →Guideline-based

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.
| ECOG performance status (with Karnofsky) | ECOG 0 (KPS 90–100) |
|---|
→ECOGECOG 0
- ECOG：ECOG 0: Fully active, no restrictions
- Karnofsky correspondence：KPS ~90–100
- Performance grading：Good performance (ECOG 0–2 / KPS ≥ 60): generally able to tolerate systemic anticancer therapy
| ECOG performance status (with Karnofsky) | ECOG 5 (KPS 0) |

→ECOGECOG 5
- ECOG：ECOG 5: Dead
- Karnofsky correspondence：KPS ~0

Common questions
What is Performance Status ECOG / Karnofsky?
This tool maps ECOG (0–5) to Karnofsky (0–100) performance status and flags the performance threshold for systemic anticancer therapy.
How is Performance Status ECOG / Karnofsky calculated? What is the core formula?
ECOG 0 = KPS 90–100, 1 = 70–80, 2 = 50–60, 3 = 30–40, 4 = 10–20, 5 = 0. NCCN commonly uses ECOG ≤ 2 or KPS ≥ 60 as the systemic-therapy threshold.
When is Performance Status ECOG / Karnofsky used?
Use to record performance status, convert between the two scales, and gauge tolerance of systemic therapy.
What are the key clinical points for Performance Status ECOG / Karnofsky?
Good performance (ECOG 0–2 / KPS ≥ 60) generally tolerates systemic therapy, while poorer status favors supportive or palliative care. (original synthesis · not guideline verbatim) The two scales correspond approximately, not exactly, so conversion is a guide. Assessment has inter-rater variability, so the most recent representative status is recorded.
What are the limits and cautions when using Performance Status ECOG / Karnofsky?
For licensed clinicians and clinical researchers. Interpret results with history, investigations and local protocols; not a diagnosis or prescription, and not a substitute for multidisciplinary decision-making or local guidelines.
How is Performance Status ECOG / Karnofsky calculated in practice? Can you show a worked example?
Inputs: ECOG performance status (with Karnofsky) ECOG 0 (KPS 90–100) → Result: ECOG ECOG 0（ECOG: ECOG 0: Fully active, no restrictions, Karnofsky correspondence: KPS ~90–100, Performance grading: Good performance (ECOG 0–2 / KPS ≥ 60): generally able to tolerate systemic anticancer therapy） Inputs: ECOG performance status (with Karnofsky) ECOG 5 (KPS 0) → Result: ECOG ECOG 5（ECOG: ECOG 5: Dead, Karnofsky correspondence: KPS ~0, Performance grading: —）
