The prognostic value of WHO performance status in relation to quality of life in advanced colorectal cancer patients

We demonstrate in ACC patients that PF, as assessed by patients using the EORTC QLQ-C30, is superior in terms of prognostic value to WHO PS as scored by physicians. Our data support to include the results of baseline EORTC QLQ-C30 PF instead of WHO PS as a stratification parameter in oncology trials.
