The prevalence of sleep disruptions have been reported in
30-50% of cancer patients. Most insomnia cases that involve
cancer patients occur in various stages of the disease, with a
particular emphasis in the advanced stages. In the literature,
insomnia is a specific sleep disruption that is more defined in
cancer patients as a symptom or clinical disorder. In oncology
patients, insomnia is not only one symptom but a cluster
of symptoms that are associated with many risk factors.
Better evaluation of the risk factors in cancer patients will
be of great assistance for the treatment of sleep disorders
in cancer patients. Since there are various diagnostic tests
for insomnia, it is important that the diagnosis and follow
up is in parallel with these methods. The methods should
be proven reliable to validate diagnosis and outcomes for
oncology patients.
