Lymphedema is a common complication after mastectomy in women with breast cancer. Several methods have been described to assess and diagnose lymphedema, one of the most studied being the perimeter and ultrasonography. However, the reliability of these methods and the correlation between them are still controversial. The aim of this study was to analyze the reliability of cytometry and ultrasound imaging in the assessment of lymphedema after mastectomy in women with breast cancer and to study the correlation between them. A cross-sectional study was conducted in 29 women with mastectomy after breast cancer. Lymphedema in the arm was measured both with cytometry and ultrasonography. Reliability was calculated with intraclass correlation coefficient. The correlation between the two methods was carried out with the Pearson correlation coefficient. Both cytometry (M1: α = 0.999, ICC = 0.996; M2: = α = 0.998, ICC = 0.994) and ultrasonography (M1: α = 0.992, ICC = 0.976; M2: = α = 0.991, ICC = 0.973) are reliable methods to assess lymphedema in the arm. No significant correlation was found between them ( > 0.05). Cytometry and ultrasonography appear to be adequate for the measurement of edema in women with breast cancer after mastectomy. However, for an accurate measurement of lymphedema, these measurements should not be used interchangeably.
淋巴水肿是乳腺癌女性乳房切除术后的常见并发症。已经描述了几种评估和诊断淋巴水肿的方法，其中研究最多的是周长和超声检查。然而，这些方法的可靠性及其之间的相关性仍然存在争议。本研究旨在分析细胞仪和超声成像在评估乳腺癌女性乳房切除术后淋巴水肿中的可靠性，并研究它们之间的相关性。 对 29 名接受过乳腺癌乳房切除术的女性进行了横断面研究。使用细胞仪和超声检查测量手臂淋巴水肿。使用组内相关系数计算可靠性。用皮尔逊相关系数进行两种方法之间的相关性分析。细胞仪（M1：α=0.999，ICC=0.996；M2：α=0.998，ICC=0.994）和超声检查（M1：α=0.992，ICC=0.976；M2：α=0.991，ICC=0.973）均为可靠的手臂淋巴水肿评估方法。两者之间未发现显著相关性（>0.05）。 细胞仪和超声检查似乎适用于测量乳腺癌女性乳房切除术后的手臂水肿。然而，为了准确测量淋巴水肿，不应将这些测量方法互换使用。
