Cancer has a paper looking at the prognostic implication of physician-patient disagreement about performance status. The data are taken from a several multi-center therapy trials involving ~1600 patients with metastatic lung or colorectal cancer in which patients and physicians independently rated performance status (using ECOG and/or Karnofsky scores). For some reason these data are from trials done in 1987-1990. It's unclear to me why such old data were used...no trials since then employed both physician and patient assessment of functional status?
