EORTC QLQ-BR23 and FACT-B for the assessment of quality of life in patients with breast cancer: a literature review

Abstract

Background: This study aims to compare the development, characteristics and validity of two widely used tools in the breast cancer population, the EORTC QLQ-BR23 and the FACT-B. Methods: A literature search was conducted using Ovid MEDLINE, OLDMEDLINE, Embase, Embase Classic and the Cochrane Central Register of Controlled Trials to identify relevant studies. Results: Both tools were found to be reliable and valid. The QLQ-BR23 focuses on physical function, whereas the FACT-B emphasizes emotional well-being. Scoring, item format, organization and response options differ between questionnaires. Conclusion: Overall, both questionnaires are effective in assessing breast cancer-specific quality of life. Clear similarities and differences between the two tools exist. Decision-making between the questionnaires should be based on the purpose and design of the study.
