A randomized controlled trial comparing two types of pneumatic compression for breast cancer-related lymphedema treatment in the home.

Purpose: Pneumatic compression devices (PCDs) are used in the home setting as adjunctive treatment for lymphedema after acute treatment in a clinical setting. PCDs range in complexity from simple to technologically advanced. The objective of this prospective, randomized study was to determine whether an advanced PCD (APCD) provides better outcomes as measured by arm edema and tissue water reductions compared to a standard PCD (SPCD) in patients with arm lymphedema after breast cancer treatment.

Local tissue water in at-risk and contralateral forearms of women with and without breast cancer treatment-related lymphedema.

Background: Quantitative measurements to help detect incipient or latent lymphedema in patients at risk for breast cancer treatment-related lymphedema (BCRL) are potentially useful supplements to clinical assessments. Suitable measurements for routine use include arm volumes, arm bioimpedance, and local tissue water (LTW) determined from the tissue dielectric constant (TDC). Because BCRL initially develops in skin and subcutis, measures that include whole arms may not be optimally sensitive for detecting the earliest changes.

Suitability of single tissue dielectric constant measurements to assess local tissue water in normal and lymphedematous skin.

Previous reports described the use of average tissue dielectric constant (TDC) measurements to assess local tissue water and its change. Our goal was to determine if a single TDC measurement could be used in place of the average of multiple measurements. The comparison criteria used to test this was the extent to which single and averaged measurements yielded similar TDC values in both normal and lymphedematous tissue.

Local tissue water assessed by tissue dielectric constant: anatomical site and depth dependence in women prior to breast cancer treatment-related surgery.

Assessing local tissue water using tissue dielectric constant (TDC) values is useful to evaluate oedema/lymphoedema features and their change. Knowledge of anatomical site and tissue depth dependence of TDC values could extend this method's utility. Our goal was to compare TDC values obtained at anatomically paired sites and to investigate their depth dependence.

Measurement decisions for clinical assessment of limb volume changes in patients with bilateral and unilateral limb edema.

Background And Purpose: Therapy-related changes in limb volumes often are estimated using summated segmental volumes based on adjacent circumference measurements. The purposes of this study were: (1) to determine the effect of different segment lengths on calculated volume reductions after complete decongestive therapy and (2) to determine the effect of excluding posttherapy control limb volumes on calculated reductions in edema volume in patients with unilateral limb lymphedema.

Subjects: This two-part retrospective study was conducted using data from patients with bilateral leg lymphedema (n=70) and data from patients with unilateral arm lymphedema (n=75) and patients with unilateral leg lymphedema (n=45).
