A new study reported in Lymphology discusses a new way to detect breast-cancer related lymphedema that is one of the most feared outcomes of breast cancer treatment and a condition that affects the lymphatic system and causes psychosocial distress and physical challenges for patients. The researchers believe that because low frequency electrical current cannot travel through cell membranes, using Bioelectrical Impedance Analysis (BIA) ratios to assess lymphedema could provide a direct measure of lymph fluid outside the cells. This allows for a more accurate assessment of lymphedema using a Lymphedema Index named L-Dex ratio. The objective of the study was to evaluate the reliability, sensitivity, and specificity of a cross-sectional assessment of BIA in detecting lymphedema in a large metropolitan clinical setting.

Data was collected on 250 women that included healthy adult females, breast cancer survivors with lymphedema and women at risk of lymphedema. They demonstrated that survivors with lymphedema had significantly higher L-Dex ratios showing the possibiliuty of using BIA to discriminate between these three cohorts of women. The researchers said “Our study also demonstrates that using a more sensitive L-Dex cutoff point, allowed for BIA to catch 34% of the usually missed lymphedema cases.” “This allows for earlier treatment, which naturally leads to better outcomes for at-risk patients.”  “Given that all women who are treated for breast cancer are at risk for lymphedema, using assessment methods that can accurately identify true lymphedema cases among at-risk breast cancer survivors is of ultimate importance for clinical practice.”
