Initial radiation experience evaluating early tolerance and toxicities in patients undergoing accelerated partial breast irradiation using the Contura Multi-Lumen Balloon breast brachytherapy catheter.

摘要

PURPOSE: We reviewed our institution's experience treating patients with the Contura Multi-Lumen Balloon (SenoRx, Inc., Irvine, CA) breast brachytherapy catheter to deliver accelerated partial breast irradiation. METHODS AND MATERIALS: Forty-one patients treated with breast-conserving therapy received adjuvant radiation using the Contura catheter (34Gy in 3.4Gy fractions). Thirteen patients had Stage 0, 21 had Stage I, and 7 had Stage II breast cancer. Median followup was 8 months (range, 1-17). RESULTS: Median, minimum skin spacing was 10mm (range, 2-17). Median, maximum skin doses (% of prescribed dose [PD]) were 99.7 (range, 57.1-124.1). Eight patients were treated with a skin spacing
