Full Definition
The Eastern Cooperative Oncology Group (ECOG) performance status is a widely used clinical tool that measures a patient's level of functioning in terms of their ability to care for themselves, daily activity, and physical ability. The scale ranges from 0 (fully active) to 5 (dead), with intermediate grades reflecting varying degrees of functional impairment. This assessment is crucial for determining treatment eligibility and prognosis in thoracic oncology patients.
