L-DEX Score Uses and Definition

One area of breast cancer research that has seen progress recently is in lymphedema prevention. Daniel Reed explains what an L-DEX score is and how it is used with bioimpedance spectroscopy to reduce the risk of developing lymphedema.

Daniel Reed, DO: An L-DEX score is a quantitative way of measuring bioimpedance spectroscopy so, it is not subjective. It is not a tape measure that I do or my nurse does and has the ability to have variations.

This is a quantitative score that is performed by a machine somewhere to like an EKG reading that we do for the patients that have had breast cancer, that have had surgery, or radiation to the breast or to the arm.

So by testing the bioimpedance spectroscopy, we were able to develop a score, which has been standardised by the L-DEX company and so we can follow this each time the patient comes in, each time they are seen for a visit and it compares their surgical arm to their non-surgical arm, so that is very important that we are doing a comparison not just following some tape measure from one arm to the other, so that is basically what an L-DEX score is.

It is a reading that standardised. It is a quantitative way of measuring bioimpedance spectroscopy and we watch that score just like we will watch someone’s temperature or their blood pressure if it increases, we know we need to intervene with some sort of treatment to prevent or reduce the risk of them developing lymphedema in the surgery site or arm.
