Taxane-based chemotherapy for the treatment of breast cancer is associated with fluid retention in the extremities; however, its association with development of breast cancer-related lymphedema is unclear. We sought to determine if adjuvant taxane-based chemotherapy increased risk of lymphedema or mild swelling of the upper extremity. 1121 patients with unilateral breast cancer were prospectively screened for lymphedema with perometer measurements. Lymphedema was defined as a relative volume change (RVC) of ≥10 % from preoperative baseline. Mild swelling was defined as RVC 5- &lt;10 %. Clinicopathologic characteristics were obtained via medical record review. Kaplan-Meier and Cox proportional hazard analyses were performed to determine lymphedema rates and risk factors. 29 % (324/1121) of patients were treated with adjuvant taxane-based chemotherapy. The 2-year cumulative incidence of lymphedema in the overall cohort was 5.27 %. By multivariate analysis, axillary lymph node dissection (ALND) (p &lt; 0.0001), higher body mass index (p = 0.0007), and older age at surgery (p = 0.04) were significantly associated with increased risk of lymphedema; however, taxane chemotherapy was not significant when compared to no chemotherapy and non-taxane chemotherapy (HR 1.14, p = 0.62; HR 1.56, p = 0.40, respectively). Chemotherapy with docetaxel was significantly associated with mild swelling on multivariate analysis in comparison to both no chemotherapy and non-taxane chemotherapy groups (HR 1.63, p = 0.0098; HR 2.15, p = 0.02, respectively). Patients who receive taxane-based chemotherapy are not at an increased risk of lymphedema compared to patients receiving no chemotherapy or non-taxane adjuvant chemotherapy. Those treated with docetaxel may experience mild swelling, but this does not translate into subsequent lymphedema.
