Abstract (original English)

It is estimated that 140 to 200 million people are affected by lymphedema worldwide. Many studies have proposed targeted therapies that can be delivered systemically or locally to treat lymphedema. Since lymphedema primarily affects the skin and subcutaneous tissues, topical approaches to therapy should be considered as an attractive proposition as they can avoid systemic complications. In light of this, we conducted a systematic review of publications that analyzed the use of topical approaches to delivering targeted therapies in the treatment of lymphedema. We hypothesized that topical approaches resulted in the satisfactory treatment of lymphedema. We conducted a systematic review of publications on PubMed. The main eligibility criterion was that the articles should primarily investigate the use of topical approaches to delivering targeted therapies in the treatment of lymphedema. Consequently, we excluded papers that investigated any other delivery approaches or medical conditions. Of the 174 potential studies found in the literature, six were found to fulfill our eligibility criteria. All these studies were experimental ones on small animals (mice). The authors generally proposed different types of therapies, which could be clustered into two main groups: 1) induction of lymphangiogenesis [vascular endothelial growth factor C (VEGF-C) hydrogel or fibroblast growth factor];
