kOBCS

kOBCS calculates and documents Objective Breast Cosmesis Scale (OBCS) values from schematic drawings or photographs to provide objective assessment of breast cosmesis after breast cancer treatment.

Key Features:

• Image input: Accepts schematic drawings or photographs as input for analysis.
• Automated OBCS calculation: Computes OBCS values automatically to replace manual hand measurements.
• OBCS documentation: Records and outputs estimated OBCS values for reporting and analysis.
• Validation metrics: Demonstrated high correlation with manual measurements (r = 0.997, P < 0.001), strong agreement among users (ICC = 0.846, P < 0.001, 95% CI 0.774–0.910), high internal consistency (Cronbach's alpha = 0.991), and significant correlation with the Harvard breast cosmesis scale (r = 0.961, P < 0.001).

Scientific Applications:

• Post-treatment cosmesis assessment: Objective quantification of breast cosmesis following breast-conserving therapy in clinical research.
• Outcome reporting in oncology and reconstructive surgery: Standardized documentation of aesthetic outcomes for comparative studies and reporting.
• Validation against subjective scales: Enables comparison between objective OBCS values and subjective assessments such as the Harvard breast cosmesis scale.

Methodology:

Imports schematic drawings or photographs and performs automated calculations to estimate Objective Breast Cosmesis Scale (OBCS) values that traditionally required manual hand measurements.
