Form or function? Part 2. Objective cosmetic and functional correlates of quality of life in women treated with breast-conserving surgical procedures and radiotherapy.
BACKGROUND
Treatment-related factors that influence quality of life (QOL) for women who are diagnosed with breast carcinoma require study. This study was designed to examine the convergent validity of objective and subjective indices of cosmetic and functional status after patients undergo breast-conserving treatment (BCT) and to test the relations of the objective indicators with QOL.


METHODS
Women (n = 54 patients) who had received BCT and radiotherapy for Stage 0-II disease for whom the diagnosis duration ranged from 9 months to 18 years completed assessments of background information, perceived cosmetic and functional outcomes, and QOL. They also were administered a clinical breast examination, including objective ratings of arm edema and breast cosmesis. The patients were a subsample from the study reported by the authors in an accompanying article that is presented in this issue.


RESULTS
The findings revealed positive cosmetic and functional treatment outcomes, such that 82% of patients had no or minimal arm edema, and 70% of patients evidenced good or excellent cosmetic results. Convergent validity was demonstrated for the objective and subjective assessments of cosmetic and functional treatment outcomes. In addition, women who had more arm edema reported poorer QOL with regard to depressive symptoms (P < 0.05) and fear of disease recurrence (P < 0.05).


CONCLUSIONS
The findings from this study and those reported in the accompanying article reveal that functional treatment outcomes, such as arm edema and breast specific pain, are important correlates of QOL even many years after patients undergo BCT and radiotherapy. Both subjective and objective indicators of treatment outcomes are useful predictors of QOL.
