🎗️ 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.
Performance Status ECOG / Karnofsky
ECOG performance status (with Karnofsky)
When to use
Use to record performance status, convert between the two scales, and gauge tolerance of systemic therapy.
How it works
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.
Key points
- 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.
