General description
Performance status, a measure of a patient's functional capacity, is frequently used to estimate the prognosis of individual patients and to select or stratify patients for clinical trials of anticancer therapies.
The most commonly used scales that can be used to quantify the performance status are the Karnofsky Performance Status, consisting of 11 stages ranging from 100 (normal health) to 0 (death) and the Eastern Cooperative Oncology Group (ECOG) performance status, a five-grade performance scale ranging from 0 (fully active) to 5 (death).

Result ranges for ECOG Performance Status

1 – Restricted in physically strenuous activity but ambulatory and able to carry out work of a light or sedentary nature, e.g., light house work, office work.
2 – Ambulatory and capable of all selfcare but unable to carry out any work activities; up and about more than 50 % of waking hours.
3 – Capable of only limited selfcare; confined to bed or chair more than 50 % of waking hours.
4 – Completely disabled; cannot carry on any selfcare; totally confined to bed or chair.
5 – Dead.
