Perioperative variables associated with surgical site infection in breast cancer surgery

Summary Despite the fact that breast operations are usually categorized as clean procedures, higher surgical site infection (SSI) rates are reported. This study aimed to determine the perioperative variables related to SSI in breast cancer patients. Medical records of breast cancer patients undergoing surgery between January 2005 and August 2007 at a university based hospital were reviewed. Preoperative, intraoperative, and postoperative clinical data from 199 patients were extracted and analysed. Overall, the SSI rate was 19.1% (38 cases). SSI was associated with a high body mass index ( P  = 0.001), history of diabetes mellitus ( P P P P  = 0.003) and neoadjuvant therapy ( P  = 0.003). Breast-conserving operations were less frequently associated with SSI than were radical procedures (mastectomy alone and mastectomy followed by immediate reconstruction) ( P  = 0.0001).
