How to Use This Calculator
  1. Review the ECOG performance status scale descriptions: 0 = fully active to 5 = deceased.
  2. Select the score that best describes the patient's current functional capacity.
  3. Read the ECOG score and its clinical interpretation for treatment planning.
  4. Review Karnofsky Performance Score (KPS) equivalent for comparison with older literature.
  5. Use performance status to guide treatment intensity — ECOG >= 3 often limits aggressive chemotherapy.

What each input means

ECOG score (0–5)
0=fully active, 1=restricted strenuous activity, 2=ambulatory >50%, 3=bed/chair >50%, 4=completely disabled, 5=dead.
Oral intake (0=normal, 1=reduced, 2=mouthfuls)
Current oral intake level for PPI calculation.
Edema present (0=no, 1=yes)
Presence of peripheral edema.
Dyspnea at rest (0=no, 1=yes)
Breathlessness at rest.
Delirium present (0=no, 1=yes)
Presence of delirium or altered consciousness.

What each result means

ECOG Performance Status
0–5 scale (lower is better functional status).
Karnofsky (KPS) estimate
Approximate Karnofsky score (0–100, higher is better).
Palliative Prognostic Index
PPI score (Morita et al.): >6 = <3 wk survival, 4–6 = <6 wk, <4 = >6 wk.
Estimated prognosis (weeks)
Rough survival estimate based on PPI score.
Phase I trial eligible (0/1)
Most phase I trials require ECOG 0–1.
Standard chemo eligible (0/1)
Standard chemotherapy typically requires ECOG 0–2.
Palliative care only (0/1)
ECOG 3–4 generally indicates palliative-only approach.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    ECOG score (0–5) = 1, Oral intake (0=normal, 1=reduced, 2=mouthfuls) = 0, Edema present (0=no, 1=yes) = 0, Dyspnea at rest (0=no, 1=yes) = 0 = 5 input(s) provided
  2. Calculate ECOG Performance Status
    ECOG Performance Status = 1
    1 = 1
  3. Calculate Karnofsky (KPS) estimate
    Karnofsky (KPS) estimate
    80 = 80
  4. Calculate Palliative Prognostic Index
    Palliative Prognostic Index
    0 = 0
  5. Calculate Estimated prognosis
    12 = 12
