Breast cancer-related lymphedema (BCRL) is a debilitating condition. The recommended treatment is based on decongestive lymphedema therapy (DLT) with two separate phases: a short-term intensive phase to reduce lymphedema volume and a long-term maintenance phase to stabilize it. Optimizing compression therapy and compliance during maintenance phase are key factors for long-term control of lymphedema. The primary objective of this pilot prospective open-label randomized study was to assess the benefit of a new auto-adjustable nighttime arm sleeve (MOBIDERM® Autofit) on lymphedema volume during the maintenance phase after the intensive phase.

Forty women with BRCL were consecutively enrolled and randomized (D0) for 1 month in 1:1 ratio either in night-use group: with MOBIDERM® Autofit (on top of a daytime compression hosiery), or in no night-use group: without MOBIDERM® Autofit (daytime hosiery alone). From Day 31 to Day 90, all patients were fitted with MOBIDERM® Autofit. Primary endpoint was lymphedema volume variation between Day 0 and Day 30. Secondary endpoints were compliance, quality of life (LYMQOL arm questionnaire), functional symptoms (heaviness, limb use limitation, pain), sleep quality, and safety.

In ITT population, between Day 0 and Day 30, mean lymphedema volume increase was higher in no night-use group with 92.9 mL (i.e., 3.2%) than in night-use group with 46.7 mL (i.e., 1.80%), p = 0.757. Between Day 30 and Day 90, all patients fitted with MOBIDERM® Autofit, lymphedema volume remained stable in both groups. The device improved functional symptoms and function domain of the LYMQOL arm questionnaire. MOBIDERM® Autofit was worn overnight almost 85% of the nights. It was well accepted by the patients and no adverse reaction leading to permanent device discontinuation occurred.

Our results suggest that MOBIDERM® Autofit offers clinical benefits during maintenance phase of lymphedema treatment and enhances patient’s self-management.
