Comparison of Intermittent Pneumatic Compression Pump as Adjunct to Decongestive Lymphatic Therapy against Decongestive Therapy Alone for Upper Limb Lymphedema after Breast Cancer Surgery: A Systematic Review and Meta-Analysis

Abstract

<b><i>Background:</i></b> Breast cancer is among the most prevalent malignancies in women worldwide, with substantial morbidity and mortality. Upper limb lymphedema (ULL) is a common complication after breast cancer surgery that affects patients’ daily activities and quality of life. Decongestive lymphatic therapy (DLT) and intermittent pneumatic compression (IPC) therapy are 2 primary treatment methods for ULL. <b><i>Objectives:</i></b> This study aimed to compare the efficacy of DLT with IPC versus DLT alone in the management of ULL following breast cancer surgery. <b><i>Method:</i></b> PubMed Central, SCOPUS, EMBASE, MEDLINE, Cochrane Trial Registry, Google Scholar, and <ext-link ext-link-type="uri" xlink:href="http://Clinicaltrials.gov" xmlns:xlink="http://www.w3.org/1999/xlink">Clinicaltrials.gov</ext-link> databases were comprehensively searched for randomized controlled trials (RCTs) comparing DLT with IPC and DLT alone in patients with breast cancer-related ULL. The risk of bias was evaluated using the RoB 2 tool. Pooled effect sizes were calculated using random-effects models. <b><i>Results:</i></b> A total of 1,894 citations were identified by the systematic search. Of them, 9 RCTs were included in the analysis. The pooled standardized mean difference (SMD) for percentage volume reduction was 0.63 (95% confidence interval [CI]: −0.24 to 1.50; <i>I</i>² = 90.9%), showing no significant difference between the DLT alone and DLT combined with IPC (<i>p</i> = 0.15). Pain and heaviness scores were also comparable between the groups. However, there was a significant difference in external rotation joint mobility (SMD = 0.62; 95% CI: 0.08–1.16; <i>I</i>² = 23.8%), favoring DLT with IPC. <b><i>Conclusions:</i></b> Our findings suggest that DLT with IPC and DLT alone showed similar findings in managing ULL after breast cancer surgery, with DLT with IPC showing a greater impact on external rotation joint mobility. Healthcare providers should consider patient preferences and individual factors when selecting the most appropriate treatment modality for ULL management.
