Quality of life in breast cancer patients: Associations with optimism and social support

Abstract

<i>Background/Objective</i>: The purpose of this study was to examine quality of life (QoL) in breast cancer patients from Colombia and to explore the relationship between QoL, habitual optimism, and social support. <i>Method</i>: A sample of 95 breast cancer patients treated in a hospital in Bogotá were administered the QoL instrument EORTC QLQ-C30 and the Life Orientation Test LOT-R. Additionally, they were asked to indicate from whom (physicians, friends, nurses, etc.) they wished and received social support. Reference data for the EORTC QLQ-C30 and the LOT-R were taken from a representative sample of the general Colombian population. <i>Results</i>: The breast cancer patients showed detriments to their QoL on most functioning scales and symptom scales of the EORTC QLQ-C30, while their general assessments of health and QoL were not worse than those of the controls. Optimism was positively correlated with QoL. Most patients wanted and received social support from their physicians and friends/family. <i>Conclusions</i>: The results suggest that optimism helps patients better cope with disease. A general assessment of global QoL cannot replace the more specific assessments of the functioning domains and symptoms.
