Insomnia in men treated with radical prostactectomy for prostate cancer

Résumé 0

This study assessed the prevalence, clinical characteristics and risk factors for insomnia in patients treated with radical prostatectomy for prostate cancer. A total of 327 patients completed a battery of questionnaires assessing sleep and related issues (i.e. anxiety, depression, fatigue, quality of life). Results indicated that 31.5% of the patients currently reported non-specific sleep difficulties, while 18% met specific criteria for an insomnia syndrome. In most of these latter cases (95%), the insomnia was chronic (duration of 6 months or more). Nearly half of patients with an insomnia syndrome reported that the onset of their sleep difficulties followed the cancer diagnosis. A similar proportion had no comorbid clinical levels of anxiety or depression. Risk factors for the presence of an insomnia syndrome included a younger age, a worse prognosis, and the presence of intestinal, pain, depressive, and androgen blockade-related symptoms. Thus, insomnia is a frequent problem associated with prostate cancer, that often occurs independently of anxiety and depression, but seems to be influenced by the presence of physical and psychological symptoms associated with prostate cancer and its treatment.
