The aim of this study is to analyse the safety and satisfaction of women included in the PreQ-20 trial who underwent NAC and who underwent mastectomy and immediate reconstruction with prepectoral polyurethane implants. Material and Methods: The patients included in the study belong to the prospective study PreQ-20. The study group consisted of patients who underwent immediate reconstruction after primary systemic therapy. The control groups consisted of patients with immediate reconstruction and adjuvant chemotherapy (control group 1) and patients with an infiltrating carcinoma or in situ ductal carcinoma who did not require chemotherapy (control group 2). Results: The study included 157 women, 58 (36.9%) of whom underwent primary systemic therapy. The indication for genetic study was significantly greater for the study group (87.9%) than for control groups 1 (49.1%) or 2 (30.4%). Seventy-two (45.9%) of the patients underwent bilateral mastectomy (BM), a procedure that was performed significantly more frequently in the study group (69%) than in control groups 1 (30.2%) or 2 (34.8%). The incidence rate for BM after complete pathologic response was 78%. There were no statistically significant differences in the number of complications between the groups. Implant loss was significantly more frequent in control group 1 (13.2%) than in the study group (3.4%) and control group 2 (2.2%). Conclusions: Mastectomy with prepectoral polyurethane implant reconstruction in patients with neoadjuvant chemotherapy presented a similar incidence of complications compared with patients who underwent primary surgery. There is a high rate of BM in women with NAC.<\/jats:p>","DOI":"10.3390\/cancers15041113","type":"journal-article","created":{"date-parts":[[2023,2,10]],"date-time":"2023-02-10T01:35:29Z","timestamp":1675992929000},"page":"1113","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Safety and Quality of Life in Women with Immediate Reconstruction with Polyurethane Implants after Neoadjuvant Chemotherapy: Outcomes from The Preq-20 Trial"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3340-4402","authenticated-orcid":false,"given":"Benigno","family":"Acea-Nebril","sequence":"first","affiliation":[{"name":"Breast Unit, Department of General Surgery, University Hospital Complex A Coru\u00f1a, 15006 A Coru\u00f1a, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7141-7570","authenticated-orcid":false,"given":"Alejandra","family":"Garc\u00eda-Novoa","sequence":"additional","affiliation":[{"name":"Breast Unit, Department of General Surgery, University Hospital Complex A Coru\u00f1a, 15006 A Coru\u00f1a, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Carmen","family":"Cereijo-Garea","sequence":"additional","affiliation":[{"name":"Breast Unit, University Hospital Complex A Coru\u00f1a, 15006 A Coru\u00f1a, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Carmen","family":"Conde Iglesias","sequence":"additional","affiliation":[{"name":"Breast Unit, Ginecology Service, University Hospital Complex A Coru\u00f1a, 15006 A Coru\u00f1a, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alberto","family":"Bouz\u00f3n Alejandro","sequence":"additional","affiliation":[{"name":"Breast Unit, Department of General Surgery, University Hospital Complex A Coru\u00f1a, 15006 A Coru\u00f1a, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Carlota","family":"D\u00edaz Carballada","sequence":"additional","affiliation":[{"name":"Breast Unit, Ginecology Service, University Hospital Complex A Coru\u00f1a, 15006 A Coru\u00f1a, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,2,9]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"645","DOI":"10.1016\/0959-8049(94)90537-1","article-title":"Neoadjuvant versus adjuvant chemotherapy in premenopausal patients with tumours considered too large for breast conserving surgery: Preliminary results of a randomized trial: S6","volume":"30","author":"Scholl","year":"1994","journal-title":"Eur.
