High body mass index and smoking predict morbidity in breast cancer surgery: a multivariate analysis of 26,988 patients from the national surgical quality improvement program database.

Objective:The purpose of this study was to examine the incidence of complications of breast cancer surgery in a multi-institutional, prospective, validated database and to identify preoperative risk factors that predispose to these complications. Background:There is an increased emphasis on clinical outcomes to improve the quality of surgical care. Although mastectomy and breast conserving surgery have low risk for complications, few US studies have examined the incidence of these complications in large, multicenter patient populations. The broad scale of the National Surgical Quality Improvement Program (NSQIP) data set facilitates multivariate analysis of patient characteristics that predispose to development of postoperative complications in breast cancer surgery. Methods:A prospective, multi-institutional study of patients undergoing mastectomy and breast conserving surgery was performed from the National Surgical Quality Improvement Program from 2005 to 2007. Study subjects were selected as a random sample of patients at more than 200 participating community and academic medical centers. Thirty-day morbidity was prospectively collected and the incidence of postoperative complications was determined, with particular emphasis on superficial and deep surgical site infections. Multivariate logistic regression was performed to identify independent risk factors for postoperative wound infections in each. Results:A total of 26,988 patients were identified who underwent mastectomy (N = 10,471) and breast conserving surgery (N = 16,517). As expected, the overall 30-day morbidity rate for all procedures was low (5.6%), with significantly higher morbidity for mastectomies (4.0%) than breast conserving surgery (1.6%, P < 0.001). The most common complications in all procedures were superficial surgical site infections and deep surgical site infections. Independent risk factors for development of any wound infection in patients undergoing mastectomy were a high body mass index, smoking, and diabetes (ORs = 1.8, 1.6, 1.8). In patients who had a lumpectomy, a high body mass index, smoking, and a history of surgery within 90 days prior to this procedure (ORs = 1.7, 1.9, 2.0) were independent risk factors. Conclusions:Although complication rates in breast cancer surgery are low, wound infections remain the most common complication. A high body mass index and current tobacco use were the only independent risk factors for development of a postoperative wound infection across all procedures. This study highlights the benefit of a multi-institutional database in assessing risk factors for adverse outcomes in breast cancer surgery.

Complications after mastectomy and immediate breast reconstruction for breast cancer a claims-bas ed analysis

Objective:To evaluate complications after postmastectomy breast reconstruction, particularly in the setting of adjuvant radiotherapy. Background:Most studies of complications after breast reconstruction have been conducted at centers of excellence; relatively little is known about complication rates in irradiated patients treated in the broader community. This information is relevant for decision making in patients with breast cancer. Methods:Using the claims-based MarketScan database, we described complications in 14,894 women undergoing mastectomy for breast cancer from 1998 to 2007 and who underwent immediate autologous reconstruction (n = 2637), immediate implant-based reconstruction (n = 3007), or no reconstruction within the first 2 postoperative years (n = 9250). We used a generalized estimating equation to evaluate associations between complications and radiotherapy over time. Results:Wound complications were diagnosed within the first 2 postoperative years in 2.3% of patients without reconstruction, 4.4% patients with implants, and 9.5% patients with autologous reconstruction (P < 0.001). Infection was diagnosed within the first 2 postoperative years in 12.7% of patients without reconstruction, 20.5% with implants, and 20.7% with autologous reconstruction (P < 0.001). A total of 5219 (35%) women received radiation. Radiation was not associated with infection in any surgical group within the first 6 months but was associated with an increased risk of infection in months 7 to 24 in all 3 groups (each P < 0.001). In months 7 to 24, radiation was associated with higher odds of implant removal in patients with implant reconstruction (odds ratio = 1.48; P < 0.001) and fat necrosis in those with autologous reconstruction (odds ratio = 1.55; P = 0.01). Conclusions:Complication risks after immediate breast reconstruction differ by approach. Radiation therapy seems to modestly increase certain risks, including infection and implant removal.

Cost analysis of implant-based breast reconstruction with acellular dermal matrix.

Abstract A comparative cost analysis of breast reconstruction using acellular dermal matrix (ADM) and traditional tissue expander-/implant-based techniques was carried out. Medicare reimbursement costs were calculated for tissue expander/implant alone (TE/I), TE/I with ADM (TE/I + ADM), and single-stage implant (SSI) with ADM (SSI + ADM). The most expensive procedure at baseline was TE/I + ADM (

Use of Acellular Dermal Matrix in Postmastectomy Breast Reconstruction: Are All Acellular Dermal Matrices Created Equal?

AbstractThe purpose of this study was to evaluate complications and patient satisfaction after pedicled transverse rectus abdominis myocutaneous (TRAM) and deep inferior epigastric perforator (DIEP) flap reconstruction at a single institution. There were 346 patients identified from 1999 to 2006 who underwent 197 pedicled TRAM and 217 DIEP flap reconstructions. Flap complication rates were similar between groups, whereas pedicled TRAM reconstructions had higher rates of abdominal bulge (9.5% vs. 2.3%, P = 0.0071) and hernias (3.9% vs. 0%, P = 0.0052). DIEP flap patients had significantly higher general satisfaction (81.7% vs. 70.2%, P = 0.0395), whereas aesthetic satisfaction was similar between groups. Furthermore, DIEP flap patients, particularly those undergoing bilateral reconstructions, were more likely to choose the same type of reconstruction compared with pedicled TRAM patients (92.5% vs. 80.7%, P = 0.0113). Understanding the differences in complications and satisfaction will help physicians and patients make informed decisions about abdominal-based autologous breast reconstruction.
