PURPOSE
The Objective Breast Cosmesis Scale (OBCS) is an objective method that documents the aesthetic changes in breast cancer patients. This work evaluates the kOBCS software (http://www.kobcs.info) which simplifies the estimation of the OBCS values.
METHODS
Five schematic drawings were photographed and imported into the kOBCS. Thirty photos of breast cancer patients were imported into kOBCS; 20 users (experts and non-experts) evaluated the photographs on two different settings. Subjective evaluation was performed using the Harvard breast cosmesis scale.
RESULTS
There was a highly significant correlation between the OBCS values based on hand measurements and the values estimated by kOBCS (r = 0.997, P < 0.001). Agreement among the users using the kOBCS was strong with high statistical significance (ICC = 0.846, P < 0.001, 95% CI 0.774-0.910, Cronbach's alpha = 0.991). Results of the subjective analyses and mean OBCS values as estimated by kOBCS correlated significantly (r = 0.961, P < 0.001).
CONCLUSIONS
The kOBCS is a reliable and reproducible easy-to-use software for reporting breast cosmesis following breast-conserving therapy.
目的
客观乳房美容量表（OBCS）是一种客观方法，可记录乳腺癌患者的美学变化。本研究评估了简化 OBCS 值评估的 kOBCS 软件（http://www.kobcs.info）。
方法
拍摄了五张示意图并将其导入 kOBCS。将 30 张乳腺癌患者的照片导入 kOBCS；20 名使用者（专家和非专家）在两种不同的设置下对照片进行评估。使用哈佛乳房美容量表进行主观评估。
结果
基于手工测量的 OBCS 值与 kOBCS 估计值之间存在高度显著的相关性（r=0.997，P<0.001）。使用 kOBCS 的用户之间的一致性很强，具有高度统计学意义（ICC=0.846，P<0.001，95%CI 0.774-0.910，Cronbach's alpha=0.991）。主观分析结果和 kOBCS 估计的平均 OBCS 值之间存在显著相关性（r=0.961，P<0.001）。
结论
kOBCS 是一种可靠且可重复的、易于使用的软件，可用于报告保乳治疗后乳房美容效果。
