Breast cancer-related lymphedema (BCRL) occurs in approximately 40% of patients after axillary lymph node dissection (ALND), radiation therapy (RT), or chemotherapy. First-line palliative treatment involves the use of compression garments and specialized massage. Reparative microsurgeries are a second-line treatment, but both compression and surgical therapy are most effective in the early stages of LE development. Identifying patients at the highest risk for BCRL would allow for earlier and more effective treatment.
Breast cancer-related lymphedema (BCRL) occurs in similar to 40% of patients after axillary lymph node dissection (ALND), radiation therapy (RT), or chemotherapy. First-line palliative treatment utilizes compression garments and specialized massage. Reparative microsurgeries have emerged as a second-line treatment, yet both compression and surgical therapy are most effective at early stages of LE development. Identifying patients at the highest risk for BCRL would allow earlier, more effective treatment. Perometric arm volume measurements, near-infrared fluorescent lymphatic imaging (NIRF-LI) data, and blood were collected between 2016 and 2021 for 40 study subjects undergoing treatment for breast cancer. Plasma samples were evaluated using MILLIPLEX human cytokine/chemokine panels at pre-ALND and at 12 months post-RT. A Mann-Whitney t-test showed that G-CSF, GM-CSF, IFN-2 alpha, IL-10, IL-12p40, IL-15, IL-17A, IL-1 beta, IL-2, IL-3, IL-6, and MIP-1 beta were significantly higher at pre-ALND in those presenting with BCRL at 12 months post-RT. MIP-1 beta and IL-6 were significantly higher at pre-ALND in those who developed dermal backflow, but no BCRL, at 12 months post-RT. Plasma IL-15, IL-3, and MIP-1 beta were elevated at 12 months after RT in those with clinical BCRL. These findings establish BCRL as a perpetual inflammatory disorder, and suggest the use of plasma cytokine/chemokine levels to predict those at highest risk.
