Breast cancer patients experience poor sleep quality, significantly impacting their overall quality of life (QoL). Early screening for sleep issues is crucial for this population.
Area of Science:
- Oncology
- Sleep Medicine
- Psychosocial Oncology
Background:
- Sleep disturbances are common in breast cancer patients.
- The interplay between sleep quality and quality of life (QoL) requires further investigation.
- The suitability of different sleep assessment tools in this population is not well-established.
Purpose of the Study:
- To assess sleep quality in breast cancer patients.
- To examine the relationship between sleep quality and QoL.
- To compare the performance of three sleep questionnaires.
Main Methods:
- Cross-sectional study of 533 breast cancer patients.
- Utilized Pittsburgh Sleep Quality Index (PSQI), Insomnia Severity Index (ISI), and Jenkins Sleep Scale (JSS).
- Assessed QoL using the EORTC QLQ-C30 instrument.
Main Results:
- Breast cancer patients exhibited poor sleep quality compared to the general population (effect sizes 0.97-1.76).
- QoL was significantly impaired across all domains, with sleep quality showing the highest impairment (d = 1.70).
- Sleep quality strongly correlated with all QoL components; questionnaire choice influenced results.
Conclusions:
- High prevalence of sleep problems necessitates routine screening in breast cancer care.
- Addressing sleep disturbances is vital for improving QoL in breast cancer survivors.
- Standardized assessment tools are important for consistent research findings.
