Purpose:
Subjective scoring is the most widely used approach in reporting the cosmetic outcome after breast-conservative therapy. This work introduces an objective system to document the breast cosmetic changes using nonstandardized photographs without scale calibration.
Methods And Materials:
Two hundred twenty-eight photographs of 114 breast cancer patients were analyzed. Baseline photographs were taken after breast-conservation surgery and before partial breast irradiation. Further photographs were taken during followup. The photographs were taken with a frontal view of the patient and without any skin marks for scaling. The baseline and the last followup photographs were analyzed by measuring certain anatomic distances (representing the nipple displacement and the asymmetry in breast dimensions and contour) to calculate the objective breast cosmesis score (OBCS). The measurements represent the nipple displacement and the asymmetry in breast dimensions and contour. Same photographs were scored subjectively by a multidisciplinary team (MDT) using the Harvard breast cosmesis scale. The patient-reported self-scoring was also recorded.
Results:
The MDT results were favorable (excellent∖good) in 72.3% of the photographs and adverse in 27.7%. Agreement among the MDT members was strong (intraclass correlation coefficient = 0.798, p < 0.001, 95% CI: 0.753-0.937, Cronbach's alpha = 0.809). The patient self-scoring was satisfactory in 82.5% of the cases and nonsatisfactory in 17.5%. The results of the OBCS ranged between 0.0 and 20.4 with a median value of 4.5. There was a strong significant correlation between the OBCS and both the MDT subjective scoring (p < 0.001) and the patient self-scoring (p < 0.001).
Conclusions:
The OBCS seems to be eligible for the objective assessment of cosmesis after breast-conservative therapy using nonstandardized photographs without scale calibration.
