Radioactive Seed Localization Versus Wire-Guided Localization for Nonpalpable Breast Cancer: A Cost and Operating Room Efficiency Analysis

Background This study aimed to compare the cost and resource use between our first-year experience using breast-conserving surgery (BCS) with radioactive seed localization (RSL) and the previous-year standard practice of BCS with wire-guided localization (WGL) for patients with nonpalpable breast cancer at a large Canadian tertiary center. Methods For this retrospective cohort study, data for BCS cases with RSL was collected from 1 April 2015 to 31 March 2016 and for BCS cases with WGL from 1 April 2014 to 31 March 2015. Results The study compared 153 WGL patients with 194 RSL patients. The two groups had no significant demographic differences. The average cost per patient for RSL, including opportunity costs, was $250.90 versus $1130.41 for WGL. Dedicated allocated radiology appointments to RSL increased (9 per day), and fewer radiologists were required for these procedures per day. Patients were transported to the operating room more quickly for RSL procedures (120 vs. 254 min; p
