  1. Notes. Advanced Stage was defined as regional or distant disease. Performance Status is the Karnofsky Performance Status, which ranges from 0 to 100 (where 0 = deceased and 100 = no sign of disease). Comorbidity indicates the presence of a comorbid disease. Chemo, Hormone, Radiation, and Surgery indicate receipt of the respective treatment. Statistically significant (p < .01) differences across ethnic groups are indicated with an asterisk (*).
