Patient Selection and Technical Considerations in Nipple-Sparing and Areola-Sparing Mastectomy

Breast cancer involvement of the nipple-areola complex and implications for nipple-sparing mastectomies: a retrospective observational study in 137 patients

Introduction

Nipple-sparing mastectomy (NSM) has gained much attention by enhancing the aesthetic outcome in breast carcinoma patients. The aim of this study was to assess the prevalence of malignant affection of the nipple-areola complex (NAC) in breast carcinoma patients and its correlation with prognostic factors for breast cancer.

Patients and methods

This study included 137 female patients diagnosed with breast carcinoma at different disease stages who were admitted to our surgical oncology unit at Suez Canal University Hospital from June 15, 2014 to January 25, 2017. We excluded patients with evidence of nipple involvement as ulceration or patients with previous breast surgery with periareolar incisions. This study was designed to test the hypothesis that the NAC can be spared in certain selected patients. All studied participants provided a full history and underwent general and local clinical examinations, pre-operative laboratory tests, and radiological and pathological evaluations.

Results

The mean age of the study population was 47.39 ± 8.01 years. Among the patients, the NAC was affected in 12 (11.40%) patients. Patients with NAC involvement showed a significantly larger tumor size of more than 4 cm and a shorter tumor-nipple distance of less than 2 cm (p = 0.000). Lymph node metastasis was associated with NAC involvement (p = 0.001), with increased risk when more than 10 lymph nodes were involved (p = 0.007). Lymphovascular invasion was a significant predictor of NAC involvement (p = 0.014). Multifocal as well as multicentric tumors were significantly associated with NAC involvement (p = 0.016 and 0.003, respectively). NAC involvement was more likely in Estrogen receptor (ER) and Progesterone receptor (PR) patients than in ER+ and PR+ patients (p = 0.000), while Human epidermal receptor (HER+) patients were more likely to have NAC involvement than HER patients (p = 0.000). Additionally, stage ΙΙΙ cancer was significantly associated with NAC involvement (p = 0.041), and histological grade III disease carried a greater risk than grade I disease of NAC involvement (p = 0.008).

Conclusion

The incidence of NAC affection among breast carcinoma patients who underwent mastectomy and axillary clearance was associated with important parameters, such as tumor size, areola edge-tumor distance, lymph node affection, hormonal receptor status and lymphovascular invasion. Accordingly, NAC-preserving surgeries could be tailored to patients with favourable tumor characteristics.

Patient-Report Satisfaction and Health-Related Quality of Life in TiLOOP® Bra-Assisted or Implant-Based Breast Reconstruction Alone

INTRODUCTION

Implant-based breast reconstructions (IBBR) using alternatives to acellular dermal matrixes are increasing. Data on complications are limited, and information concerning health-related quality of life (HR-QoL) following the use of these synthetic meshes do not exist.

METHODS

Between January 2006 and January 2013, patients undergoing immediate or delayed-immediate IBBR with or without titanium covered polypropylene mesh (TiLOOP® Bra) were investigated. HR-QoL was assessed using the validated self-reporting BREAST-Q questionnaire. Patient demographics and complications were evaluated retrospectively. Stepwise regression backward elimination analysis was performed to identify influential factors on each BREAST-Q domain.

RESULTS

Of the 90 women, 42 had IBBR alone and 48 in combination with TiLOOP® Bra. The mean follow-up was 18 months in the TiLOOP® Bra and 17.5 months in the implant alone group (p = 0.827). The overall complication rate was 21.1 %, with 14.6 % in the TiLOOP® Bra and in 28.6 % in the implant alone group (p = 0.105). Capsular contraction rate was 4.4 % in the TiLOOP® Bra and 16.7 % in the implant alone group (p = 0.052). The analysis of the HR-QoL showed no significant differences between the groups. Surgeries prior to IBBR had a positive influence on HR-QoL. TiLOOP® Bra was associated with a negative effect on "satisfaction with breast" (β = -5.72; p < 0.001), as it was no longer observed for "satisfaction with outcome" and other domains.
