Eastern Cooperative Oncology Group (ECOG) / Zubrod Score

Determines ability of patient to tolerate therapies in serious illness, specifically for chemotherapy, simpler than the Karnofsky Scale.

Advice

The ECOG Score may be slightly better than Karnofsky for discriminating prognostically and, as an adaptation of Karnofsky, is likely to be at least similar in other domains. It is also simpler to use, and therefore may be preferred.

Management

We are unaware of validated management algorithms using the ECOG Score.

Critical Actions

The ECOG Score and other performance scales should be used in the holistic assessment of cancer patients, though their accuracy as prognostic tools in individual cases is not yet proved.
