Nipple-Sparing Mastectomy in Patients with Prior Breast Irradiation
Plastic and Reconstructive Surgery, 2014
Background: Reconstruction in the setting of prior breast irradiation is conventionally considered a higher-risk procedure. Limited data exist regarding nipple-sparing mastectomy in irradiated breasts, a higher-risk procedure in higher-risk patients. Methods: The authors identified and reviewed the records of 501 nipple-sparing mastectomy breasts at their institution from 2006 to 2013. Results: Of 501 nipple-sparing mastectomy breasts, 26 were irradiated. The average time between radiation and mastectomy was 12 years. Reconstruction methods in the 26 breasts included tissue expander (n = 14), microvascular free flap (n = 8), direct implant (n = 2), latissimus dorsi flap with implant (n = 1), and rotational perforator flap (n = 1). Rate of return to the operating room for mastectomy flap necrosis was 11.5 percent (three of 26). Nipple-areola complex complications included one complete necrosis (3.8 percent) and one partial necrosis (3.8 percent). Complications were compared between this subset of previously irradiated patients and the larger nipple-sparing mastectomy cohort. There was no significant difference in body mass index, but the irradiated group was significantly older (51 years versus 47.2 years; p = 0.05). There was no statistically significant difference with regard to mastectomy flap necrosis (p = 0.46), partial nipple-areola complex necrosis (p = 1.00), complete nipple-areola complex necrosis (p = 0.47), implant explantation (p = 0.06), hematoma (p = 1.00), seroma (p = 1.00), or capsular contracture (p = 1.00). Conclusion: In the largest study to date of nipple-sparing mastectomy in irradiated breasts, the authors demonstrate that implant-based and autologous reconstruction can be performed with complications comparable to those of the rest of their nipple-sparing mastectomy patients.

Background: The major focus of research when addressing nipple reconstruction has been on developing new techniques to provide for long-lasting nipple projection. Rarely, has the outcome of nipple reconstruction as it relates to postoperative morbidity, particularly after implant-based breast reconstruction, been analyzed. Methods: A "matched-pair" study was designed to specifically answer the question whether a history of radiotherapy predisposes to a higher complication rate after nipple reconstruction in patients after implant-based breast reconstruction. Only patients with a history of unilateral radiotherapy who underwent bilateral mastectomy and implant-based breast reconstruction followed by bilateral nipple reconstruction were included in the study. Results: A total of 17 patients (i.e. 34 nipple reconstructions) were identified who met inclusion criteria. The mean age of the study population was 43.5 years (range, 23e69). Complications were seen after a total of 8 nipple reconstructions (23.5 percent). Of these, 7 complications were seen on the irradiated side (41.2 percent) (p Z 0.03). Conclusion: While nipple reconstruction is a safe procedure after implant-based breast reconstruction in patients without a history of radiotherapy the presence of an irradiated field converts it to a procedure with a significant increase in postoperative complication rate.
Breast Reconstruction following Nipple-Sparing Mastectomy
Plastic and Reconstructive Surgery, 2014
Background: Nipple-sparing mastectomy is increasingly used for treatment and prevention of breast cancer. Few data exist on risk factors for complications and reconstruction outcomes. Methods: A single-institution retrospective review was performed between 2007 and 2012. Results: Two hundred eighty-five patients underwent 500 nipple-sparing mastectomy procedures for breast cancer (46 percent) or risk reduction (54 percent). The average body mass index was 24, and 6 percent were smokers. The mean follow-up was 2.17 years. Immediate breast reconstruction (reconstruction rate, 98.8 percent) was performed with direct-to-implant (59 percent), tissue expander/implant (38 percent), or autologous (2 percent) reconstruction. Acellular dermal matrix was used in 71 percent and mesh was used in 11 percent. Seventy-seven reconstructions had radiotherapy. Complications included infection (3.3 percent), skin necrosis (5.2 percent), nipple necrosis (4.4 percent), seroma (1.7 percent), hematoma (1.7 percent), and implant loss (1.9 percent). Positive predictors for total complications included smoking (OR, 3.3; 95 percent CI, 1.289 to 8.486) and periareolar incisions (OR, 3.63; 95 percent CI, 1.850 to 7.107). Increasing body mass index predicted skin necrosis (OR, 1.154; 95 percent CI, 1.036 to 1.286) and preoperative irradiation predicted nipple necrosis (OR, 4.86; 95 percent CI, 1.0197 to 23.169). An inframammary fold incision decreased complications (OR, 0.018; 95 percent CI, 0.0026 to 0.12089). Five-year trends showed increasing numbers of nipple-sparing mastectomy with immediate reconstruction and more single-stage versus two-stage reconstructions (p < 0.05). Conclusions: Nipple-sparing mastectomy reconstructions have a low number of complications. Smoking, body mass index, preoperative irradiation, and incision type were predictors of complications.

With the increasing popularity of skin-sparing mastectomy techniques, implant-based breast reconstruction and use of perioperative radiation therapy, there is a growing need to scrutinize the effects they have on breast reconstruction. This study examined the effect of radiation on implant-based breast reconstruction in patients who had skin-sparing or conventional mastectomies in terms of complication, reoperation, and capsular contracture rates. A retrospective review of 227 implant-based breast reconstructions in 132 mastectomy patients by a single surgeon was undertaken. All cases occurred over a four-year period (2006-2009) at a single institution. Complication, re-operation, and capsular contracture rates were tabulated against immediate and delayed reconstruction, skin-sparing and conventional mastectomy implant-based reconstruction, and irradiated and non-irradiated groups. Chi-square test was performed for statistical analysis. The overall complication and reoperation rates...
The Impact of Radiation on Surgical Outcomes of Immediate Breast Reconstruction
The American Surgeon, 2011
We sought to determine the differences in surgical outcomes associated with adjuvant radiation versus no radiation in patients undergoing concurrent breast oncologic and reconstructive operations. A retrospective review of patients who underwent combined oncologic and plastic surgeries for breast diseases from January 2005 to June 2010 was compared for demographic factors and outcomes by receipt of radiation therapy. During the study period, 175 patients were identified; 25.7 per cent received radiation therapy. Mean patient age was 51 years and median follow-up was 355 days. Overall, 80.2 per cent of patients underwent mastectomy; 19.8 per cent partial mastectomy; 42.1 per cent autologous tissue reconstruction; and 54.8 per cent implant-based reconstruction. There were no significant differences between radiated and nonradiated patients in rates of overall or oncoplastic-specific complications. Lymphedema was the only complication seen more frequently in the radiated arm ( P = 0.03...

Background. Breast-conserving surgery has become the standard approach for about 80% of patients treated for primary breast cancer in most centres. However, mastectomy is still required in case of multicentric and/or large tumours or where recurrences occur after conservative treatment. When a total mastectomy is performed, the removal of the nipple areola complex (NAC) is a strongly debated issue. In fact, although removal of the NAC greatly increases the patient's sensation of mutilation, and the risk of tumor involvement of the areola is reported as a very variable percentage, NAC excision still remains the standard treatment.

Nipple-sparing mastectomy (NSM) is increasingly offered to women for therapeutic and prophylactic indications. Although, clinical series have been described, there are few studies describing risk factors for complications. The objective of this study is to evaluate the incidence of complications in a series of consecutive patients submitted to NSM and differences between clinical risk factors, breast volume, and different incision types. In a cohort-designed study, 158 reconstructed patients (invasive/in situ cancer and high risk for cancer) were stratified into groups based on different types of incision used (hemiperiareolar, double-circle periareolar, and Wise-pattern). They were matched for age, body mass index, associated clinical diseases, smoking, and weight of specimen. Also included were patients treated with adjuvant chemotherapy and postoperative radiotherapy. Mean follow-up was 65.6 months. In 106 (67 %) patients, NSM was performed for breast cancer treatment and in 52 (32.9 %) for cancer prophylaxis. Thirty-nine (24.6 %) patients were submitted to hemi-periareolar technique, 67 (42.4 %) to double-circle periareolar incision, and 52 (33 %) to Wise-pattern incision. The reconstruction was performed with tissue expander and implant-expander. Local recurrence rate was 3.7 % and the incidence of distant metastases was 1.8 %. Obese patients and higher weight of specimen had a higher risk for complications. After adjusting risk factors (BMI, weight of specimen), the complications were higher for patients submitted to hemi-periareolar and Wise-pattern incisions. This follow-up survey demonstrates that NSM facilitates optimal breast reconstruction by preserving the majority of the breast skin. Selected patients can have safe outcomes and therefore this may be a feasible option for breast cancer management. Success depends on coordinated planning with the oncologic surgeon and careful preoperative and intraoperative management. Surgical risk factors include incision type, obesity, and weight of breast specimen.
Direct-To-Implant and 2-Stage Breast Reconstruction After Nipple Sparing Mastectomy
Annals of Plastic Surgery, 2019
Breast reconstruction after nipple sparing mastectomy (NSM) plays, nowadays, a fundamental role in breast cancer management. There is no consensus on the best implant-based reconstruction technique, considering 2 stages (expander-prosthesis) or direct-to-implant (DTI). A retrospective review of consecutive adult female patients who underwent NSM with breast reconstruction over a 3-year period (January 2013 to December 2015) was performed. Patients were divided into 2 groups according to the type of reconstruction: expander/ prosthesis (group A) and DTI (group B). Anamnestic data were collected. Number and type of procedures, complications and esthetic satisfaction were registered and compared. Fifty-six patients were included in group A (34.6%) and 106 in group B (65.4%). Complications associated with the 2 types of breast reconstruction were not different (P = 0.2). Patients in group A received a higher number of total surgical procedures (considering revisions, lipostructures and contralateral symmetrizations) than those in group B (2.5 ± 0.69 and 1.88 ± 1.02, P = 0.0001). Satisfaction with breast reconstruction resulted higher in group A (7.5 ± 2.6 and 6 ± 1.9, P = 0.0004). At the multivariate analysis, chemotherapy and radiotherapy were not correlated with complications, regardless of the group (odds ratio, 0.91 and 2.74, respectively). Radiotherapy and chemotherapy did not even influence the esthetic result, regardless of the group (P = 0.816 and P = 0.521, respectively). Prosthetic breast reconstructions, both in a single and in 2 stages, are welcomed by patients and have relatively low and almost equivalent complication rates, independent of other factors such as chemotherapy, radiotherapy, lymphadenectomy, smoking and age. In our experience, 2-stage breast reconstruction, although requiring more operations, is associated with a higher esthetic satisfaction. Patients who perform a DTI breast reconstruction after NSM should be informed of the high probability of surgical revision.
Breast reconstruction and post-mastectomy radiation practice
Radiation Oncology, 2013
Purpose The goal of this study was to explore the perspectives and practice of radiation oncologists who treat breast cancer patients who have had breast reconstruction. Methods In 2010, an original electronic survey was sent to all physician members of the American Society of Radiation Oncology, National Cancer Research Institute-Breast Cancer Studies Group in the United Kingdom, Thai Society of Therapeutic Radiology and Oncology, Swiss Society of Radiation Oncology, and Turkish Radiation Oncology Society. We identified factors associated with radiation oncologists who treat breast cancer patients with reconstruction performed prior to radiation and obtained information regarding radiation management of the breast reconstruction. Results 358 radiation oncologists responded, and 60% of the physicians were from the United States. While 64% of participants agree or strongly agree that breast image affects a woman’s quality of life during radiation, 57% feel that reconstruction challen...
Nipple-sparing mastectomy with implant reconstruction: the Westmead experience
ANZ Journal of Surgery, 2014
Background: Nipple-sparing mastectomy (NSM) involves the removal of all breast tissue with preservation of the breast skin envelope and nipple-areola complex (NAC). The objective of this study was to report the outcomes from our initial experience with NSM. Methods: We retrospectively analysed 87 women who underwent 118 NSMs between October 2008 and May 2012. Results: Indications for NSM were 60 (51%) primary cancer, 15 (13%) residual/ recurrent disease, 39 (33%) risk reduction and 4 (3%) benign pathology. Implant loss (n = 10) was associated with subcutaneous placement (P = 0.01), post-operative seroma and infection (P = 0.028, 0.001), skin flap necrosis (P = 0.007) and NAC loss (P = 0.027). Capsular contraction was related to adjuvant radiotherapy (P = 0.044). Local recurrence occurred in four patients, and NAC recurrence with invasive cancer occurred in one patient after a median follow-up of 30 months. Conclusion: Our Australian NSM series adds to the published literature supporting the oncological safety of NSM for early-stage breast cancer and risk reduction.
