During 2-stage breast reconstruction in patients with unilateral breast cancer, we sometimes experience cases in which the contralateral breast volume changes greatly. However, few studies have examined volumetric changes in the contralateral breast during 2-stage breast reconstruction. Changes in contralateral breast volume between the first and second operations were examined in patients who underwent 2-stage unilateral breast reconstruction between February 2013 and August 2016 (123 patients aged 49.1 ± 8.6 years). Influences of age, postoperative treatment, and body weight on volumetric changes in the contralateral breast were statistically analyzed. A positive correlation was observed between changes in body weight and contralateral breast volume (correlation coefficient = 0.218, = .015). Weight loss was particularly important: all patients who lost more than 3 kg showed decreased contralateral breast volume ( = .010). Age and postoperative treatment had no significant effect on the change in contralateral breast volume. Change in body weight, and massive weight loss in particular, is an important factor for volumetric changes in the contralateral breast during 2-stage unilateral breast reconstruction.
在单侧乳腺癌患者进行二期乳房重建期间，我们有时会遇到对侧乳房体积变化很大的情况。然而，很少有研究探讨二期乳房重建期间对侧乳房的体积变化。对2013年2月至2016年8月期间接受二期单侧乳房重建的患者（123例，年龄49.1±8.6岁），检查了首次手术与第二次手术之间对侧乳房体积的变化。对年龄、术后治疗和体重对侧乳房体积变化的影响进行了统计学分析。观察到体重变化与对侧乳房体积之间存在正相关（相关系数=0.218，P=.015）。体重减轻尤为重要：所有体重减轻超过3kg的患者对侧乳房体积均减小（P=.010）。年龄和术后治疗对对侧乳房体积变化无显著影响。体重变化，尤其是大量体重减轻，是二期单侧乳房重建期间对侧乳房体积变化的一个重要因素。
