ECOG Performance Status
Describes functional capacity in oncology patients across six grades.
When to use
Functional assessment of adults with cancer before and during treatment.
Pearls and pitfalls
- The grade describes what the patient can do, not tumor burden or prognosis alone.
- The difference between grades 2 and 3 is time spent out of bed or chair.
- The assessment is subjective and should be made by the same observer when possible.
- Grade 5 means death and should not be used as a triage category.
