Abstract
Purpose
The purpose of this studywas to examine fatigue, sleepdisturbances, andqualityof life (QOL) among patientswithbreast cancerreceivingradiotherapy.
Methods
Acrosssectional, descriptivedesignwas used. Data werecollected throughquestionnaires distributed to 201 breast cancerpatients ina hospital. Thedatawere analyzed using SPSS 21.0.
Results
The fatigue scores showed significant differences depending on exercise and duration since diagnosis. The sleep disturbance scores showed significant differences depending on duration since diagnosis. QOL scores showed significant differences depending on exercise, duration since diagnosis, andtreatment site. Fatigueandsleepdisturbances (r=.40, p<.001) showedstatisticallysignificant positivecorre-lations, whilefatigueandQOL(r=-.55, p<.001),andsleepdisturbancesandQOL(r=-.45, p<.001)showed statistically significant negative correlations. Themultipleregressionanalysis, whichwas usedto determinethevariables influencing on QOL after radiotherapy, resulted in a significant regression model (F=23.88, p<.001), which accounted for approximately 45% of the explanatory power. Fatigue (β=-.39, p<.001) and sleep disturbances (β =-.27, p<.001) were revealedtoadverselyaffect qualityof life.
