Abstract
BACKGROUND
A culture of serious overwork in South Korea, more than other developed countries, may impact symptoms and quality of life (QOL) experienced by Korean breast cancer survivors (BCS).
OBJECTIVES
The aim of this study was to examine health-related QOL and influencing factors in BCS in Seoul, Korea, who have recovered from treatment for at least 1 year and returned to normal life and work.
METHODS
In a cross-sectional study, 199 BCS completed a self-administered questionnaire in Seoul, Korea.
RESULTS
Mean QOL scores were lower than expected, with 49% of the variance explained by depressive symptoms, physical fatigability, cognitive impairment, and social support. Psychological distress was high (67.8%), along with anxiety (47.2%) and depressive symptoms (36.7%). Participants reported a high prevalence of physical fatigability (71.1%), sleeping an average of only 6 hours per night, with 58.9% reporting poor quality sleep.
CONCLUSIONS
Quality of life was lower in Korean BCS than comparable studies in the United States, although participants received care at a premiere medical center. Depressive symptoms and anxiety were common and did not taper off over the 5 years after diagnosis, unlike BCS elsewhere. Korean survivors experienced significant physical fatigability, much higher than reported in a US study of mixed male and female cancer survivors. Overwork was not a significant predictor of QOL, although 30% of employed women reported working 45 to 90 hours weekly.
IMPLICATIONS FOR PRACTICE
Findings demonstrate the importance of continued efforts to mitigate these symptoms in clinical survivorship care, as well as future research, to provide avenues for improving QOL for BCS, particularly in Korea.
