Relationship between sleep disturbance, symptoms, and alcohol use in breast cancer survivors attending Sydney Cancer Survivorship Clinic

Symptom Clusters in Survivorship and Their Impact on Ability to Work among Cancer Survivors

BACKGROUND

Cancer survivors often experience a range of symptoms after treatment which can impact their quality of life. Symptoms may cluster or co-occur. We aimed to investigate how symptoms and symptom clusters impact the ability to work among cancer survivors.

METHODS

We used symptom severity data and ability to work data routinely collected from cancer survivors attending a survivorship clinic after primary treatment with curative intent. We defined symptom clusters using single linkage and a threshold on the rescaled distances of <10. We then conducted a logistic regression to examine how symptoms and symptom clusters were related to the ability to work.

RESULTS

We analysed data from 561 cancer survivors, mean age 58 years and 1.5 years post diagnosis, with mixed diagnoses including breast (40.5%), colorectal (32.3%), and haematological cancers (15.3%). Limitations to work ability were reported by 34.9% of participants. Survivors experiencing pain, emotional, and cognitive symptom clusters were 14-17% more likely to report limitations in their ability to work. Older survivors and those with a higher stage disease were more likely to report limitations in their ability to work.

CONCLUSION

A better understanding and management of symptom severity and symptom clusters may help the sizable proportion of cancer survivors experiencing symptoms to participate in work after treatment.

Sleep health in young women with breast cancer: a narrative review

PURPOSE

The purpose of this narrative review was to synthesize the evidence on sleep health in young women with breast cancer and provide recommendations for clinical practice and research.

METHODS

Multiple databases were searched (OVID Medline, OVID PsycINFO, OVID Embase, and Scopus) using the search terms "breast neoplasm", "young women", "sleep", "sleep disturbance", "sleep problems", "sleep deficiency", and "insomnia". There were 467 titles and abstracts screened, and 82 full-text papers were reviewed, yielding 11 research publications for inclusion.

RESULTS

Sleep problems are prevalent among young women with breast cancer and are associated with vasomotor symptoms of menopause and psychological symptom distress. The evidence, however, is weak due to methodological and design aspects of the studies.

CONCLUSIONS

Poor sleep health in women with breast cancer is a clinically relevant problem that persists after treatment. As sleep is multidimensional and multifactorial, future research should evaluate sleep with objective sleep measures as well as self-reports; consider longitudinal designs; include factors that potentially contribute to poor sleep quality, such as physical and psychological symptom distress, family stressors, and competing life demands for this age group; and explore the perspective of this younger population of survivors on sleep. For clinical practice, survivorship visits should incorporate sleep assessment for all breast cancer survivors, especially younger women.

Lifestyle and quality of life in patients with early-stage breast cancer receiving adjuvant endocrine therapy

PURPOSE OF REVIEW

A comprehensive approach to survivorship care for women with early-stage, hormone-receptor positive breast cancer should systematically include the proactive assessment and adequate management of endocrine therapy-associated symptoms, in order to assure optimal balance between preserving quality of life (QOL) and maximizing treatment adherence. We reviewed the recent literature focused on lifestyle factors, including physical activity, diet and nutrition, weight management, smoke, and alcohol behavior, and their link with symptomatology and QOL among women receiving adjuvant endocrine therapy.

RECENT FINDINGS

Recent studies confirm the safety, feasibility, and effectiveness of lifestyle interventions in mitigating several common endocrine therapy-related effects, including musculoskeletal pain, fatigue, and insomnia, and in improving physical and emotional wellbeing as well as overall health-related QOL among women with early-stage breast cancer.

SUMMARY

Healthy lifestyle behaviors have the potential to modulate the downstream impact of endocrine therapy and improve QOL among women with early-stage breast cancer. Considerations for real-world clinical care implementation emerged, including a need to evaluate the long-term uptake of healthy behaviors and facilitate the postintervention maintenance of an improved lifestyle. Some facilitators to health promotion in breast cancer survivors were also suggested, such as individualized and one-to-one supervised programs, and digital solutions providing real-time feedback, building on personalized, direct patient engagement.
