Comparison of IPC Therapy as an Alternative or an Adjunct to MLD Within CDT for BCRL

Breast cancer is the most common malignancy among women worldwide and remains the leading cause of cancer-related mortality in women. Breast cancer-related lymphedema (BCRL) is one of the most important complications of breast cancer treatment. It may occur due to lymphatic system damage caused by surgery and/or radiotherapy, or as a result of tumor-related lymphangiogenesis, leading to interstitial fluid accumulation. BCRL can develop immediately after treatment or months to years later. BCRL is associated with swelling, heaviness, discomfort, weakness, increased risk of infection, and progressive chronicity, which together result in upper extremity dysfunction and reduced quality of life. Compared with women without lymphedema, patients with BCRL report more frequent pain, decreased shoulder mobility, reduced upper extremity strength, impaired daily activities, and sensory disturbances. The standard treatment for BCRL is complete decongestive therapy (CDT), which consists of manual lymph drainage (MLD), compression, skin care, and exercise. Intermittent pneumatic compression (IPC) has also been proposed as a treatment option, and the 2023 consensus report of the International Society of Lymphology emphasized the need for further studies evaluating IPC in combination with MLD. However, the number of studies directly comparing IPC with MLD, or evaluating their combined use, is limited and results remain inconsistent. Some trials reported no significant difference between MLD and IPC in terms of limb volume reduction, while others demonstrated additional benefits of IPC in relieving heaviness and tension. The role of IPC in CDT, whether as a replacement for MLD or as an adjunct, is not yet clearly defined. The purpose of this study is to investigate the acute effects of using IPC instead of MLD, or in combination with MLD, within CDT on arm circumference, arm volume, shoulder range of motion, and quality of life in patients with BCRL.
