INTRODUCTIONīreast reconstruction is a critical part of the comprehensive care following mastectomy in patients diagnosed with breast cancer. Meaning: The focus of postoperative breast reconstruction should be aesthetics and quality of life, rather than breast size. Question: Is preoperative breast cup measurement a reliable way to determine true breast size, and is it able to be used to determine postoperative breast size?įindings: Preoperative breast cup size is weakly correlated with mastectomy specimen weight with other patient factors, such as BMI and chest circumference, playing a large role in mastectomy specimen weight. Thus, the conversation with the patient should focus on breast appearance and quality of life rather than postreconstruction breast size. There is a positively weak correlation between preoperative breast cup size and mastectomy weight, providing evidence for the difficulty of estimating postoperative breast cup size. Covariates assessed in the regression showed BMI significant for all types, age for TS type, and SS type for breast surgeon and chest circumference. There were positively weak correlations using nonparametric correlation analysis for breast cup size to mastectomy weight in patients who underwent TS (r = 0.375 p = 0.004), SS (r = 0.353 p <0.001), and NS (r = 0.246 p = 0.004) mastectomy. Results:Ģ43 patients were evaluated as a part of this study who underwent either total-simple (TS 29), skin-sparing (SS 146), or nipple-sparing (NS 68) bilateral mastectomy. Covariates that were assessed included chest circumference, surgical oncologist, BMI, race, and age. Cup size and mastectomy weight were our only independent and dependent variables, respectively. This is a retrospective study that evaluated patients who underwent bilateral mastectomy at an academic center between 2019–2021. This study aims to evaluate the association between patient self-reported breast cup size and mastectomy specimen weight as a way to determine postreconstruction breast cup size. Breast cup sizing irregularities exist due to discrepancy between garment manufacturers and patient reported measurements making it difficult to assess true preoperative and definitive postoperative breast cup size.
