Based on the results of cluster analysis, LE
and PC seem to be the most common symptom
clusters in advanced cancer patients,
which is consistent with the results of another
study.In patient Groups 2 and 6 with poorer
prognosis, there is an association between PI
and AI. Their concurrence may aggravate the
expression of AD and appear to relate to
PC and LE.When all the clusters are present,
as in patient Group 6, PI, AD, and PC are the
most prominent ones.
