ABSTRACT

In this paper, we propse a quantitative research by investigating the subcutaneous tissue elasticity by using ultrasonography in lymphedema patients after breast cancer surgery. Lymphedema patients who took breast cancer operation were included. Thickness of subcutaneous tissue was assessed at two spots; 10cm below elbow (forearm) and 10cm above elbow (upper arm), not only in affected side but also in sound side. By using probe attached to real-time pressure sensor, stress-strain curves were obtained. We defined tissue elasticity as slope of that curve at range of 7.5~15% of strain to avoid toe region. By comparing the elasticity of normal side and that of affected side, lymphedema tissues were classified into ‘softer’ and ‘harder’ tissues. Overall 30 cases of lymphedema tissues and 30 cases of sound tissues were checked. The difference of the elasticity between normal and affected side ranged from -3.98 N/m2 to 1.40 N/m2. The lymphedema tissues were classified into 17 softer tissues and 13 harder tissues. No demographic and clinical values, including clinical stage of lymphedema, showed statistically meaningful differences between two groups. Evaluation of subcutaneous tissue elasticity with ultrasonography and real-time pressure sensor could be one of the useful tools for investigation of lymphedema tissue characteristics.
