Eastern Cooperative Oncology Group
Also written as: ECOG — Eastern Cooperative Oncology Group
Research cooperative that developed the widely-used ECOG performance status scale for assessing cancer patients' functional capacity.
Full Definition
A major cancer clinical trials cooperative group established in 1955 that has contributed significantly to oncology research and clinical practice. ECOG is best known in clinical practice for developing the ECOG Performance Status scale, a standard tool for assessing a cancer patient's level of functioning and ability to tolerate treatment. The ECOG scale ranges from 0 (fully active) to 5 (dead) and is used worldwide in clinical trials enrollment criteria, treatment decisions, and prognosis assessment. ECOG has conducted numerous landmark clinical trials that have established standard treatments for various cancers, including lung cancer therapeutic regimens.
