A Propensity-Matched Analysis of the Influence of Breast Reconstruction on Subsequent Development of Lymphedema.
Abstract | BACKGROUND: METHODS: A review of patients undergoing axillary lymphadenectomy with or without immediate breast reconstruction from January 1, 2000, to July 1, 2013, was conducted. Comorbidities, cancer treatment, operative characteristics, and pathologic findings were reviewed. The primary outcome was postoperative lymphedema. Univariate analysis identified baseline differences between the patient groups. Cohorts were propensity-matched by age, body mass index greater than 30 kg/m, adjuvant radiation therapy, cardiovascular disease, and hypertension. Subsequent multivariate regression was performed to identify independent predictors of lymphedema among matched patients. RESULTS: A total of 4647 patients underwent breast cancer resection, with 1955 having axillary lymphadenectomy (no reconstruction, n = 1200; autologous, n = 563; implant-based, n = 192). Matching yielded a cohort of 239 reconstruction and 239 no-reconstruction patients demonstrating no differences in age, body mass index, hypertension, adjuvant radiation therapy, or axillary dissection extent. With 55.9 months' follow-up, postoperative lymphedema was diagnosed in 94 patients (19.7 percent). Reconstruction patients developed lymphedema in 19.2 percent of cases versus 20.1 percent for no- reconstruction patients (p = 0.82). Regression identified two independent predictors of lymphedema: postoperative radiation therapy (OR, 2.90; p < 0.001) and obesity (OR, 2.36; p < 0.001). CONCLUSIONS: CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.
