BCCT.core (Breast Cancer Conservative Treatment. cosmetic results) is a software created for the objective evaluation of aesthetic result of breast cancer conservative treatment using a single patient frontal photography. The lack of volume information has been one criticism, as the use of 3D information might improve accuracy in aesthetic evaluation. In this study, we have evaluated the added value of 3D information to two methods of aesthetic evaluation: a panel of experts; and an augmented version of the computational model - BCCT.core3d.
Within the scope of EU Seventh Framework Programme Project PICTURE, 2D and 3D images from 106 patients from three clinical centres were evaluated by a panel of 17 experts and the BCCT.core. Agreement between all methods was calculated using the kappa (K) and weighted kappa (wK) statistics.
Subjective agreement between 2D and 3D individual evaluation was fair to moderate. The agreement between the expert classification and the BCCT.core software with both 2D and 3D features was also fair to moderate.
The inclusion of 3D images did not add significant information to the aesthetic evaluation either by the panel or the software. Evaluation of aesthetic outcome can be performed using of the BCCT.core software, with a single frontal image.
BCCT.core（乳腺癌保守治疗。美容效果）是一款软件，用于通过单个患者正面摄影对乳腺癌保守治疗的美容效果进行客观评估。由于缺乏体积信息，这一直是一个批评，因为使用 3D 信息可能会提高美学评估的准确性。在这项研究中，我们评估了 3D 信息对两种美学评估方法的附加值：专家组；以及计算模型的增强版本 - BCCT.core3d。
在欧盟第七框架计划项目 PICTURE 的范围内，来自三个临床中心的 106 名患者的 2D 和 3D 图像由 17 名专家组成的小组和 BCCT.core 进行了评估。使用 Kappa（K）和加权 Kappa（wK）统计数据计算所有方法之间的一致性。
2D 和 3D 个体评估之间的主观一致性为中等至适度。专家组分类与 BCCT.core 软件与 2D 和 3D 特征的一致性也为中等至适度。
专家组或软件评估均未发现 3D 图像增加了明显的信息。使用单个正面图像可以使用 BCCT.core 软件进行美学效果评估。
