Cancer patients are at great risk for developing insomnia and disorders of the sleep-wake cycle. Insomnia is the most common sleep disturbance in this population and is most often secondary to physical and/or psychological factors related to cancer and/or cancer treatment.[1,2,3,4,5] Anxiety and depression, common psychological responses to the diagnosis of cancer, cancer treatment, and hospitalization, are highly correlated with insomnia.[6,7]
Sleep disturbances may be exacerbated by paraneoplastic syndromes associated with steroid production and by symptoms associated with tumor invasion, such as draining lesions, gastrointestinal (GI) and genitourinary (GU) alterations, pain, fever, cough, dyspnea, pruritus, and fatigue. Medications—including vitamins, corticosteroids, neuroleptics for nausea and vomiting, and sympathomimetics for the treatment of dyspnea—as well as other treatment factors can negatively impact sleep patterns.
Caregivers have their own emotional responses to patients' diagnoses and prognoses, and they may require coaching and emotional support separate from that offered to patients.[1,2] Caregiver roles and caregiver burden are profoundly affected by a patient's prognosis, stage of illness, and goals of care. The existing body of work on family caregivers of patients with cancer focuses primarily on a caregiver's adjustment during the acute survivorship phase, from the time of diagnosis to 2 years postdiagnosis...
Hypnotics can interfere with rapid eye movement (REM) sleep, resulting in increased irritability, apathy, and diminished mental alertness. Abrupt withdrawal of hypnotics and sedatives may lead to symptoms such as nervousness, jitteriness, seizures, and REM rebound. REM rebound has been defined as a marked increase in REM sleep with increased frequency and intensity of dreaming, including nightmares. The increased physiologic arousal that occurs during REM rebound may be dangerous for patients with peptic ulcers or a history of cardiovascular problems. Newer medications for insomnia have reduced adverse effects.
