BackgroundLymph node transfer (LNT) and lymphovenous bypass (LVB) have been described as 2 major surgical options for patients with breast cancer-related lymphedema (BCRL) who have failed conservative therapy. The objective of our study was to perform a cost-effectiveness analysis comparing LNT and LVB for the treatment of BCRL.Study DesignRates of infection, lymph leak, and failure of LNT and LVB were obtained from a previously published meta-analysis. Failure of surgery was defined as the inability to cease compression therapy postoperatively. Procedural costs were calculated from Medicare reimbursement rates. Cost of conservative management of postoperative surgical site infection, lymph leak, and continued decongestive physiotherapy after failed surgery were obtained from literature review. Average utility scores for each health state were calculated using a visual analog scale survey, then converted to quality-adjusted life years (QALYs). A decision tree was constructed, and incremental cost-effectiveness ratio was assessed at $50,000/QALY. Deterministic and probabilistic sensitivity analyses were performed to evaluate the robustness of our findings.ResultsLNT was less costly ($22,492 vs $31,927) and more effective (31.82 QALY vs 29.24 QALY) than LVB. One-way (deterministic) sensitivity analysis demonstrated that LNT became cost-ineffective when its failure rate was more than 43.8%. LVB became more cost-effective than LNT when its failure rate was less than 21.4%. Probabilistic sensitivity analysis using Monte-Carlo simulation indicated that even with uncertainty present in the variables analyzed, the majority of simulations (97%) favored LNT as the more cost-effective strategy.ConclusionsLNT is a dominant, cost-effective strategy compared to LVB for the treatment of BCRL.Copyright © 2021 American College of Surgeons.
