Abstract
Breast Retraction Assessment (BRA) is an objective evaluation of the amount of cosmetic retraction of the treated breast in comparison to the untreated breast in patients who receive conservative treatment for breast cancer. A clear acrylic sheet supported vertically and marked as a grid at 1 cm intervals is employed to perform the measurements. Average BRA value (± standard deviation) in 29 control patients without breast cancer was 1.2 cm (±0.7 cm). Average BRA value in 27 patients treated conservatively for clinical Stage I or 11 unilateral breast cancer was 3.7 cm (±2.1 cm). BRA values in breast cancer patients ranged from 0.0 to 8.5 cm. Statistical analysis revealed that tumor size, employment of adjuvant chemotherapy and use of separate radiation lymph node fields were not factors in breast retraction. Patients who received a local radiation boost to the primary tumor bed site had statistically significantly less retraction than those who did not receive a boost. Patients who had an extensive primary tumor resection had statistically significantly more retraction than those who underwent a more limited resection. In comparison to qualitative forms of cosmetic analysis, BRA is an objective test that can quantitatively evaluate factors which may be related to cosmetic retraction in patients treated conservatively for breast cancer.
