Abstract

Some evidences have been found that urine can be used as a biomarker for the detection of many types of diseases. The purpose of this study is to use permittivity of urine to assess whether different stages of breast cancer are significantly different. Changes in electrical resistance of urine samples to applied microwaves were measured over a frequency range between 10MHz to 20GHz. This is carried out by the measurement of samples' response to applied microwave energy using network vector analyzer. SPSS was used to find out the significant difference in urine permittivity values across different stages of breast cancer. The results show significant difference between stage 1 and stage 2 in all dielectric parameters of urine permittivity. Significant difference was also found between stage 2 and stage 3 in both dielectric constant and loss factor parameters while the significant difference between stage 1 and stage 3 only exists in loss factor parameter. The results suggest that it is possible to estimate the stage of breast cancer based on the dielectric properties of urine.

尿介电特性在乳腺癌分期分类中的潜力

有证据表明，尿液可以作为多种疾病检测的生物标志物。本研究的目的是利用尿液的介电常数来评估不同阶段的乳腺癌是否有显著差异。在10MHz至20GHz的频率范围内测量了尿样对微波的电阻变化。这是通过使用网络矢量分析仪测量样品对外加微波能量的响应来实现的。采用SPSS统计软件分析不同乳腺癌分期患者尿液介电常数值的差异。结果表明，1期和2期尿液介电常数各项介电参数均有显著性差异。第2级和第3级在介电常数和损耗因子参数上也存在显著差异，而第1级和第3级仅在损耗因子参数上存在显著差异。结果表明，可以根据尿液的介电性质来估计乳腺癌的分期。
