Abstract
Purpose:
The aim of the study was to evaluate the usefulness of thermography in the diagnosis of lymphedema.
Methods:
The study included 43 women after axillary dissection caused by breast cancer, whose mean age was 64.4 ± 7.8 years. The subjects were divided into two groups, with the criterion for division being the appearance of secondary lymphedema. The size of lymphedema was verified by Limb Volumes Professional 5.0; body surface temperatures were registered using a thermal camera.
Results:
In the control group, the difference in the volume of the limb on the operated side and the contralateral limb was 7.5 ± 77.7 mL (3.6%). The temperature on the nonoperated side tended to be higher than on the opposite side. In the test group, the difference in size between the limbs was 54.5 ± 312.7 mL (29.3%). In the case of mild or moderate edema, a reverse tendency was observed. While measuring the difference in the mean surface temperatures of both limbs belonging to two groups, a significance of differences at the level of p = 0.04 was observed. Moreover, a negative Spearman correlation coefficient (−0.34) was observed between the size of secondary lymphedema and the surface temperature.
Conclusion:
Noninvasive thermography can provide a valuable supplementary tool in the diagnostics of secondary lymphedema.
