The study was conducted to evaluate soft tissue hydration and mass through pattern analysis of vector plots as height, normalized resistance, and reactance measurements by bioelectric impedance vector analysis (BIVA) in patients with breast cancer.
Whole-body measurements were made with ImpediMed bioimpedance analysis SFB7 BioImp v1.55 (Pinkenba Qld 4008, Australia) in 68 adult, white, female subjects: 34 adult, white female (age 31-82) patients with breast cancer and 34 healthy volunteers matched by age, gender and BMI as a control group. The measurements were performed prior to oncological and surgical treatment, without the need for active nutritional interventions.
Mean vectors of women with breast cancer versus the healthy women groups were characterized by a slight increase of the normalized resistance and reactance components (separate 95% confidence limits, p < 0.05) indicating that there were slight differences of soft tissue hydration and mass.
The results observed in the presented study provide valuable information on the nutritional status of the patient prior to surgery. This quick assessment of the patient nutritional status can allow for early corrective intervention. Further observational research investigating these properties in larger groups would be beneficial to elucidate and/or confirm these findings.
本研究旨在通过生物电阻抗矢量分析（BIVA）对乳腺癌患者进行身高、归一化电阻和电抗测量，并通过矢量图的模式分析来评估软组织水合作用和质量。
使用ImpediMed生物阻抗分析仪SFB7 BioImp v1.55（澳大利亚昆士兰州平肯巴4008）对68名成年白人女性受试者进行全身测量：34名成年白人女性（年龄31 - 82岁）乳腺癌患者和34名年龄、性别和BMI匹配的健康志愿者作为对照组。测量在肿瘤和手术治疗前进行，无需进行积极的营养干预。
乳腺癌女性与健康女性组的平均矢量特征为归一化电阻和电抗成分略有增加（95%置信区间分别独立，p < 0.05），表明软组织水合作用和质量存在细微差异。
本研究观察到的结果为手术前患者的营养状况提供了有价值的信息。对患者营养状况的这种快速评估可以允许早期纠正干预。进一步在更大群体中研究这些特性的观察性研究将有助于阐明和/或证实这些发现。
