Fatigue (94.2%) was the most common
symptom, followed by weakness (93.9%), anorexia
(87.1%), pain (83.8%), and constipation
(64.2%). With regard to the severity of
symptoms, anorexia (1.75 0.89) was the
most serious symptom, followed by fatigue
(1.73 0.70), weakness (1.72 0.69), pain
(1.35 0.81), constipation (1.19 1.06), and
abdominal fullness (1.13 1.13) (Table 2).
As mentioned previously, to understand the
latent constructs of the 15 symptoms on admission,
we conducted an exploratory factor
analysis using the principal component
method with promax rotation. In the process
of analysis, pain complex (PC) on various sites
was separated as an independent symptom.
