Secondary lymphedema (SLE) is a debilitating complication of cancer treatment, especially for breast cancer, with rising global prevalence, yet no effective pharmacological treatment exists.Grape seed proanthocyanidin extract (GSPE), known to improve venous insufficiency, is hypothesized to benefit lymphatic insufficiency and aid in SLE management. This study investigated the therapeutic potential of GSPE using lymphedema animal models. Fifteen nineweek-old Sprague-Dawley rats (250-300 g) were used with tail lymphedema models induced in 12 rats, and 3 rats were in normal condition. The treatment group received intraperitoneal GSPE powder mixed in saline, while the control group received saline. The follow-up of tail volume showed significant edema reduction in the treatment group compared to the control group. Near-infrared fluorescence indocyanine green lymphangiography (NIRF-ICGL) and laser Doppler flowmetry imager (LDFI) confirmed improved lymphatic and blood flow functions. Histopathological analysis using H&E staining revealed reduced matrix deposition and lymphatic abnormalities supporting the therapeutic effects of GSPE in SLE. These findings demonstrate the potential of GSPE as a novel treatment for lymphedema beyond its established 2 indications. Given the limited availability of safe and effective pharmacological options, GSPE shows promise as a future therapeutic strategy for SLE management.
