Objective: Breast cancer (BC) is the most frequent cancer among women. Many BC patients suffer from sleep problems, which have a negative impact on their quality of life (QoL). Our study aims to investigate sleep problems in BC patients treated with active chemotherapy or in remission in comparison with a healthy control group (HCG), given the importance of sleep disorders and QoL. Materials and Methods: A multicenter, cross-sectional study was conducted. Four different surveys including sociodemographic characteristics questionnaire, Pittsburgh sleep quality index (PSQI), hospital anxiety and depression scale and The European Organisation for Research and Treatment of Cancer core quality of life questionnaire (QLQ-C30) were used to collect study parameters. Results: Of 164 participants, the mean age was 42.0±11.7 years. Overall PSQI median score for all participants was 6 points (range, 3-9 points). PSQI median value was higher in cancer patients compared to the control group, which were 6 points (range, 4-9 points), and 4 points (range, 3-7 points), respectively (p=0.004). The mean depression score was 5 points (range, 3-8 points) in BC patients, and 4 points (range, 2-6 points) in HCGs, respectively (p=0.025). Having BC diagnosis was an independent factor increasing the risk of bad sleep quality in compared to healthy controls (odds ratio: 2.568, 95% confidence interval: 1.169-5.645; p=0.019). Conclusion: There was a close association between poor sleep quality, depression and QoL scores in patients with BC. In patients with breast cancer, appropriate management of associated comorbidities will aid a better quality of life in these patients. |
