Change of aesthetic and functional outcome over time and their relationship to quality of life after breast conserving therapy.
OBJECTIVE
We analyzed changes in aesthetic and functional outcome over time after breast conserving therapy. Our special interest resides in the question of whether these aspects gain or loose their influence on quality of life (QoL) with temporal progress.


METHODS
This prospective single centre cohort study included 138 patients, treated with breast conserving surgery and consecutive radiotherapy. Patients completed two questionnaires one week and one year after surgery: the BCTOS (Breast Cancer Treatment Outcome Scale) to measure Functional, Aesthetic, and Breast Sensitivity Status and the EORTC (European Organisation for Research and Treatment of Cancer) C30-BR23 to assess QoL. We applied correlation and multiple regression analysis as statistical methods.


RESULTS
Aesthetic and Functional Status did not change significantly over one year, whereas Breast Sensitivity Status and several QoL subscales showed significant improvement (p < 0.0001). Correlations between BCTOS scales and EORTC subscales remain similar over time. Functional and Aesthetic Status kept a strong impact on global health (Spearman's Rho = -0.28 to -0.45 depending on time of assessment). Increasing age and poorer Functional Status shortly after surgery are predictors of a decline in global health over one year (p < 0.001).


CONCLUSIONS
Functional and aesthetic outcome after breast conserving surgery maintain their impact on QoL over a one year follow-up period and are valuable predictors of QoL.
