Introduction: Breast volume estimation is considered crucial for breast cancer surgery planning. A single, easy, and reproducible method to estimate breast volume is not available. This study aims to evaluate, in patients proposed for mastectomy, the accuracy of the calculation of breast volume from a low-cost 3D surface scan (Microsoft Kinect) compared to the breast MRI and water displacement technique. Material and Methods: Patients with a Tis/T1–T3 breast cancer proposed for mastectomy between July 2015 and March 2017 were assessed for inclusion in the study. Breast volume calculations were performed using a 3D surface scan and the breast MRI and water displacement technique. Agreement between volumes obtained with both methods was assessed with the Spearman and Pearson correlation coefficients. Results: Eighteen patients with invasive breast cancer were included in the study and submitted to mastectomy. The level of agreement of the 3D breast volume compared to surgical specimens and breast MRI volumes was evaluated. For mastectomy specimen volume, an average (standard deviation) of 0.823 (0.027) and 0.875 (0.026) was obtained for the Pearson and Spearman correlations, respectively. With respect to MRI annotation, we obtained 0.828 (0.038) and 0.715 (0.018). Discussion: Although values obtained by both methodologies still differ, the strong linear correlation coefficient suggests that 3D breast volume measurement using a low-cost surface scan device is feasible and can approximate both the MRI breast volume and mastectomy specimen with sufficient accuracy. Conclusion: 3D breast volume measurement using a depth-sensor low-cost surface scan device is feasible and can parallel MRI breast and mastectomy specimen volumes with enough accuracy. Differences between methods need further development to reach clinical applicability. A possible approach could be the fusion of breast MRI and the 3D surface scan to harmonize anatomic limits and improve volume delimitation. [ABSTRACT FROM AUTHOR]

Summary: The aim of this study is to describe the semiology for the assessment of breast asymmetry in the presence of scoliosis. Twenty-four women with right idiopathic scoliosis treated with bracing alone (23 out of 24) or with bracing and spine surgery (1 out of 24) were evaluated by physical and morphological examinations and three-dimensional (3D) surface scan. Physical examination revealed a smaller right breast in 20 women. A left costal protrusion was observed in 18 patients. Anthropomorphic analysis revealed that the right breast was higher in 19 cases, and smaller in 18 cases. The calculations from 3D scan showed the right breast to be smaller in 19 women. A strong correlation is found between clinical parameters, anthropomorphic measurements and 3D scan analysis, suggesting that a meticulous clinical examination is sufficient to evaluate breast asymmetry in patients with idiopathic scoliosis. A patient who is properly diagnosed and informed of her skeletal deformity and breast asymmetry is more likely to have realistic expectations from breast surgery. [Copyright &y& Elsevier]
