From the advanced cancer literature, Vigano and colleagues examined 136 different
variables from 22 studies and found that, after performance status, specific
signs and symptoms were the next best predictors of patient survival (Vigano
2000).
The presence of:
dyspnea,
dysphagia,
weight loss,
xerostomia,
anorexia, and
cognitive impairment
had the most compelling evidence for independent association with patient survival
in these studies.
The following table contains the range of median survivals for the various
symptoms reported in univariate analyses from these and other studies.
