Abstract

The present invention is directed to therapeutic methods using IL-6 antagonists such as antibodies and fragments thereof having binding specificity for IL-6 to improve survivability or quality of life of a patient in need thereof. In preferred embodiments these patients will comprise those exhibiting (or at risk of developing) an elevated serum C-reactive protein level or a reduced serum albumin level prior to treatment. In another preferred embodiment, the patient'"'"'s Glasgow Prognostic Score will be increased and survivability will preferably be improved.
