Although weight loss has been reported to be beneficial in the treatment of lymphedema, no studies to date have examined the use of GLP-1RAs for the treatment of secondary lymphedema. This case report describes a patient who experienced significant resolution of her breast cancer-related lymphedema after initiation of a GLP-1RA for weight loss.<\/jats:p><\/jats:sec><jats:sec><jats:title>Main symptoms and\/or important clinical findings<\/jats:title><jats:p>Nine months postoperatively the patient developed arm swelling and disability. While on adjuvant chemo and hormonal therapy, her weight increased dramatically and peaked 4 years later. Corresponding to her weight gain was significant worsening of her symptoms.<\/jats:p><\/jats:sec><jats:sec><jats:title>The main diagnoses, therapeutic interventions, and outcomes<\/jats:title><jats:p>Due to adjuvant cancer-related weight gain and inability to lose weight with diet and exercise, she was referred for evaluation and diagnosed with lymphedema. The patient started treatment with a Glucagon-like peptide 1 receptor agonist and lost 24% of her body weight over the next 13 months. The improvement in her lymphedema mirrored her weight loss. Her limb volume difference dropped from 10.3% down to 3.4% and she no longer required a compression garment. Her imaging demonstrated return of lymphatic pumping and she experienced a significant improvement in quality of life, assessed by a validated lymphedema-specific patient reported outcome (PROM). She remains on hormonal therapy, no longer needs compression and is back to regular exercise without impairment.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>GLP-1 RAs provide a potential medical option for many patients struggling with weight gain and lymphedema. We have observed by all objective measures a significant reduction in lymphedema and the elimination of compression in the case presented as a direct result of GLP-1 RA. This may also reduce a patient\u2019s BMI to the point where they become a good candidate for lymphovenous bypass or vascularized lymph node transplant when indicated.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fonc.2024.1392375","type":"journal-article","created":{"date-parts":[[2024,4,18]],"date-time":"2024-04-18T04:26:35Z","timestamp":1713414395000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":22,"title":["GLP-1 receptor agonist as an effective treatment for breast cancer-related lymphedema: a case report"],"prefix":"10.3389","volume":"14","author":[{"given":"Fionnuala","family":"Crowley","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stav","family":"Brown","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Emily J.","family":"Gallagher","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joseph H.","family":"Dayan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2024,4,18]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","DOI":"10.1016\/s1470-2045(13)70076-7","article-title":"Incidence of unilateral arm lymphoedema after breast cancer: a systematic review and meta-analysis","volume":"14","author":"DiSipio","year":"2013","journal-title":"Lancet Oncol"},{"key":"B2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijrobp.2011.05.043","article-title":"Breast cancer-related arm lymphedema: incidence rates, diagnostic techniques, optimal management and risk reduction strategies","volume":"81","author":"Shah","year":"2011","journal-title":"Int J Radiat Oncol Biol Phys"},{"key":"B3","doi-asserted-by":"publisher","DOI":"10.1245\/s10434-009-0452-2","article-title":"The risk of developing arm lymphedema among breast cancer survivors: a meta-analysis of treatment factors","volume":"16","author":"Tsai","year":"2009","journal-title":"Ann Surg Oncol"},{"key":"B4","doi-asserted-by":"publisher","DOI":"10.1002\/micr.30990","article-title":"The breast cancer-related lymphedema multidisciplinary approach: Algorithm for conservative and multimodal surgical treatment","volume":"43","author":"Ciudad","year":"2023","journal-title":"Microsurgery"},{"key":"B5","doi-asserted-by":"publisher","DOI":"10.1002\/micr.30855","article-title":"Combined lymph node transfer and suction-assisted lipectomy in lymphedema treatment: a prospective study","volume":"42","author":"Bolletta","year":"2022","journal-title":"Microsurgery"},{"key":"B6","doi-asserted-by":"publisher","DOI":"10.1097\/prs.0000000000007783","article-title":"Surgical treatment of lymphedema: A systematic review and meta-analysis of controlled trials.
