Evaluate reliability and accuracy of infrared thermography in the assessment of women wth breasts cancer. Thirty-five participants had unilateral breast cancer and 17 control subjects were assessed using infrared thermography. To evaluate reliability, two professionals, who were experienced, measured the temperature of the infrared images in two different moments, with a one-week interval. Biopsy was used as a gold standard exam with regard identify breast cancer. The analysis illustrated excellent reliability in terms of the affected, contralateral and control breasts with the intra-class correlation coefficient values ranging from 0.948 to 0.999. Standard measurement error ranged from 0.04 to 0.28 °C, and minimum detectable change deviated from 0.11 to 0.78 °C. Moreover, low to moderate accuracy were observed in terms of the establishment of the breast cancer diagnosis with values of the area under the receiver operating characteristic (ROC) curve ranging from 0.571 and 0.749. Breasts affected by cancer present higher skin temperature compared to contralateral and control. Furthermore, excellent reliability of the analysis of the infrared images and low-moderate accuracy in terms diagnosis were observed. Considering the results, infrared thermography can be applied as an instrument complement the assessment of breast cancer patients, but not for diagnostic purposes.
评估红外热成像技术在乳腺癌女性评估中的可靠性和准确性。35名参与者患有单侧乳腺癌，17名对照受试者接受了红外热成像评估。为评估可靠性，两名经验丰富的专业人员在两个不同时间测量红外图像的温度，间隔为一周。活检被用作确定乳腺癌的金标准检查。分析表明，患侧、对侧和对照乳房的可靠性极佳，组内相关系数值在0.948至0.999之间。标准测量误差在0.04至0.28°C之间，最小可检测变化在0.11至0.78°C之间。此外，在建立乳腺癌诊断方面观察到低至中等的准确性，受试者工作特征（ROC）曲线下面积值在0.571至0.749之间。与对侧和对照相比，患癌乳房的皮肤温度更高。此外，观察到红外图像分析的可靠性极佳，诊断方面的准确性为低至中等。考虑到结果，红外热成像可作为辅助评估乳腺癌患者的工具，但不能用于诊断目的。
