Abstract

Background

To analyze the relationship of objective and subjective evaluation tools of breast aesthetics, we compare the results of the BCCT.core (breast cancer conservative treatment.cosmetic results) software, a semiautomated objective symmetry evaluation tool, with those of the Aesthetic Status of the BCTOS (Breast Cancer Treatment Outcome Scale) patient questionnaire.

Materials and Methods

We included 128 patients with one-sided, primary breast cancer, treated conservatively in a prospective, exploratory study in order to assess the inter-rater reliability of the BCCT.core and the agreement between the BCCT.core and the BCTOS preoperatively, shortly and 1 year after surgery. Therefore, we use agreement rates, multiple (mk), and weighted (wk) kappa coefficients as statistical methods. Furthermore, we analyzed patient-, tumor-, and therapy-related variables as possible covariates to explain agreement.

Results

The inter-rater reliability for the semiautomated BCCT.core is very good with agreement rates up to 84% (mk = 0.80). The agreement rates of the BCCT.core and the BCTOS Aesthetic Status range between 35 and 44% subject to the different times of assessment (wk = 0.34 at best). Moreover, the patients judge their aesthetic outcome more positively than the software. None of the considered patient-, tumor-, and therapy-related covariates turned out to explain agreement.

Conclusion

The BCCT.core is a reliable instrument that shows fair agreement with patient’s perspective.
