Name of journal: Annals of surgical oncologyAbstract: BACKGROUND: NRG Oncology/NSABP trial B-40 tested the impact of adding bevacizumab (bev) to neoadjuvant chemotherapy for operable breast cancer. Secondary endpoints included rates of surgical complications after surgery in patients who did or did not receive bev.CONCLUSIONS: Overall, adding bev increased surgical complications, but most serious complications were not significantly increased. In particular, the need for surgical intervention in patients undergoing breast reconstruction with prosthetic implants was higher with bev but was not statistically significantly different. With precautions, bev can be used safely perioperatively in patients undergoing surgery for breast cancer.METHODS: A total of 1206 women with HER2-negative operable breast cancer were randomly assigned to receive one of three different docetaxel-plus-anthracycline-based regimens, without or with bev (15 mg/kg every 3 weeks) for the first 6 of 8 cycles and for 10 doses postoperatively. Surgical complications were assessed from date of surgery through 24 months following study entry.RESULTS: Early surgical complications were significantly more frequent in the bev group (25.4 vs. 18.9%; trend test p = 0.008), but most were grade 1-2. Early noninfectious wound dehiscences were infrequent and not significantly different (5.4 vs. 3.1%; trend test p = 0.15). Long-term noninfectious wound complications were significantly higher for patients receiving bev (11.8 vs. 5.1%; trend test p = 0.0007), but the incidence of grade >3 wound dehiscence was low in both groups (<1%). Among 193 patients undergoing expander or implant reconstructions, 19 (19.6%) of 97 in the bev-receiving group versus 10 (10.4%) of 96 in the non-bev group had grade >3 complications (Pearson, p = 0.11).All authors: Adams PT, Baez-Diaz L, Bear HD, Brufsky AM, Costantino JP, Fehrenbacher L, Gaur R, Geyer CE Jr, Gross HM, Kidwell KM, Mamounas EP, Margolese RG, Mehta RS, Paik S, Rastogi P, Robidoux A, Senecal FM, Swain SM, Tang G, Wolmark N, Young JA, Zoon CKFiscal year: FY2018Digital Object Identifier: Date added to catalog: 2017-05-24
