背景：淋巴水肿是乳腺癌治疗后常见的并发症，估计影响20%的乳腺癌幸存者。这种情况与许多症状有关，如活动范围受损和焦虑。广泛的方法来确定淋巴水肿手臂的体积已被描述。围度测量（CM）通常用于临床评估手臂体积，而驱水量（WD）常用于研究。该研究的目的是评估一种使用3d技术的新方法的性能，与CM和WD进行比较。方法与结果：研究对象为25例乳腺癌治疗后继发淋巴水肿患者。从CM， WD和3d相机收集所有受试者的体积数据。测量由两名物理治疗师进行，每名受试者由其中一名物理治疗师测量。通过使用混合设计方差分析对三种方法收集的数据进行分析，计算方法之间的差异估计值。结果表明，与WD相比，3d相机倾向于高估45.25 mL的体积，95%置信区间(CI) -36.31 - 126.82 （p值0.270）。相反，与WD相比，CM表现出低估体积的倾向（-24.28 mL, CI -99.78 - 51.22， p值0.521）。因此，两种方法之间没有统计学上的显著差异。结论：3d相机是一种可行的测量手臂体积的方法，与已建立的方法WD和CM水平。
Background: Lymphedema is a common complication following breast cancer treatment, estimated to affect 20% of breast cancer survivors. The condition is associated with a number of symptoms, such as impaired range of motion and anxiety. A wide range of methods for determining the volume of the lymphedematous arm have been described. Circumference measurement (CM) is commonly used in clinics to appraise arm volume, while water displacement (WD) is often used in studies. The aim of the study was to assess the performance of a new method using 3D-technology in comparison to CM and WD.Methods and Results: The study was performed on 25 subjects with lymphedema secondary to breast cancer treatment. Volumetric data from CM, WD, and the 3D-camera were gathered on all subjects. The measurements were performed by two physiotherapists, each subject being measured by one of the physiotherapist. Estimates of differences between the methods was calculated through analyzing the data collected from the three methods using mixed-design analyses of variance. The results indicated a tendency for the 3D-camera to overestimate the volume in comparison the WD by 45.25 mL, 95% confidence interval (CI) -36.31 - 126.82 (p value 0.270). Conversely, CM showed a tendency to underestimate the volume compared to WD (-24.28 mL, CI -99.78 - 51.22, p value 0.521). Thus, no statistically significant difference was found between the methods.Conclusions: The 3D-camera is a viable method for measuring arm volume, performing on level with the established methods WD and CM.
