Influence of breast reconstructive complications surgery on the systemic treatment of breast cancerB

Objective: To establish the type of post surgical complications in patients with cancer and other tumors, taken to immediate or delayed mastectomy and breast cancer reconstruction over a decade in the National Cancer Institute (NCI); also, it's association with the late start of adjuvant therapy and the relationship between neoadjuvant chemotherapy and the presence of complications. Materials and methods: A review of the medical records of patients diagnosed with breast cancer, sarcoma, or phillodes breast tumor that were performed immediate or delayed mastectomy and breast reconstruction over the years 1998 to 2008. Results: 342 patients were identified. 76% of those with locally advanced breast carcinoma. 60.53% of patients had some form of early local complication. Immediate reconstruction showed a greater percentage of complication (63% vs 49%); 67.5% of the patients from this series received neoadjuvant chemotherapy and of those, 135 (60%) presented an early local complication. The rate of adjuvant treatments started in relation to the presence or absence of local complications was 26.12 adjuvants started by 100 patients/month (IC95%: 22.2 to 30.7) in patients with early local complications vs 55.06 adjuvants started by 100 patients/month (IC95%: 45.08 to 67.23) in patients with no local complications (log-rank test, p-0.0079). Conclusions: The neoadjuvant chemotherapy increases de risk of postoperative complications in patients with breast cancer undergoing mastectomy and immediate breast reconstruction. As the presence of early local complications delay the onset of adjuvant chemotherapy. (C) 2013 Institute Nacional de Cancerologia. Published by Elsevier Espana, S.L.U. All rights reserved.
