Resumo

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 intraclass correlation coefficient values ranging from 0.948 to 0.999. Standard measurement error ranged from 0.04 to 0.28 degrees C, and minimum detectable change deviated from 0.11 to 0.78 degrees 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. (AU)
