Abstract

To evaluate retrospectively rates of local (LCR) and locoregional tumor control (LRCR) in patients with locally advanced breast cancer (LABC) who were treated with preoperative chemotherapy (PST) followed by breast conserving surgery (BCS) and either intraoperative radiotherapy with electrons (IOERT) preceding whole breast irradiation (WBI) (group 1) or with WBI followed by an external tumorbed boost (electrons or photons) instead of IOERT (group 2). From 2002 to 2007, 83 patients with clinical stage II or III breast cancer were enrolled in group one and 26 in group two. All patients received PST followed by BCS and axillary lymph node dissection. IOERT boosts were applied by single doses of 9 Gy (90% reference isodose), versus external boosts of 12 Gy (median dose, range 6 - 16) in 2 Gy/fraction (ICRU). WBI in both groups was performed up to total doses of 51 - 57 Gy (1.7- 1.8 Gy/fraction). The respective median follow-up times for groups one and two amount 59 months (range 3 - 115) and 67.5 months (range 13 - 120). Corresponding 6-year rates for LCR, LRCR, metastases free survival (FFM), disease specific survival (DSS), and overall survival (OS) were 98.5%, 97.2%, 84.7%, 89.2% and 86.4% for group one and 88.1%, 88.1%, 74%, 92% and 92% for group two, respectively, without any statistical significances. IOERT as boost modality during BCS in LABC following PST shows a trend to be superior in terms of LCR and LRCR in comparison with conventional boosts. © 2014 Wiley Periodicals, Inc.
