Comprehensive Validation Study of Quality-of-Life Questionnaire Using Objective Clinical Measures: Breast Cancer Treatment Outcome Scale (BCTOS), Brazilian Portuguese Version

摘要

Quality-of-life questionnaires (QLQs) do not correlate with objective measurements of treatment sequelae. We performed a comprehensive validation study of the Brazilian Portuguese version of the Breast Cancer Treatment Outcome Scale (BCTOS), adding physical evaluations of the main sequelae related to breast-conserving therapy (BCT). Three hundred patients were evaluated. BCTOS represented a good QLQ for BCT patients, which correlated with objective measurements.
