Introduction. Oncologic mastectomy in the setting of obesity poses challenges in achieving a flat closure that includes the lateral adiposity. The angel wing (AW) technique was developed to address this issue. We aim to demonstrate the safety of AW by evaluating incidence of arm lymphedema (AL) and decreased range of motion (dROM) in patients postmastectomy with and without the AW closure. Methods. We performed a single-center retrospective cohort study at an academic referral center of patients who underwent mastectomy with and without the AW technique from May 2014 to October 2022. Those who received breast reconstruction (immediate or delayed), partial mastectomy, and male patients were excluded. The presence of postoperative AL and dROM was evaluated. Subgroup analysis was performed for patient factors including BMI, extent of axillary surgery, PMRT, and pathologic stage. Results. A total of 390 patients met inclusion criteria. Of those, 173 (44.4%) underwent AW and 217 (55.6%) had non-AW mastectomy. Expectedly, the average BMI was significantly higher in the AW cohort (). The overall rate of AL was 51/390 (13.1%), seen in 27 (15.6%) undergoing AW and 24 (11.1%) non-AW ( value = 0.18). While the rate of dROM within the cohort was 52/390 (13.1%), 27 (15.6%) underwent AW vs. 24 (11.1%) non-AW ( value = 0.22), resulting in no statistical significance between AW and non-AW mastectomy upon subsequent development of AL or dROM. Conclusion. Our study demonstrates the AW technique does not convey an increased risk of overall AL or dROM, even when considering known risk factors such as obesity, PMRT, and extent of axillary surgery. As we strive to provide our patients with improved surgical techniques for oncologic resection, we submit that this technique is a viable and safe option for achieving the goals of cosmesis with oncologic safety.

Purpose. Breast cancer is the most common cancer among women globally, with an incidence of approximately two million cases in 2018. Organised age-based breast cancer screening programs were established worldwide to detect breast cancer earlier and to reduce mortality. Currently, there is substantial anticipation regarding risk-adjusted screening programs, considering various risk factors in addition to age. The present study investigated the discriminatory accuracy of breast cancer risk prediction models and whether they suit risk-based screening programs. Methods. Following the PICO scheme, we conducted an overview of reviews and systematically searched four databases. All methodological steps, including the literature selection, data extraction and synthesis, and the quality appraisal were conducted following the 4-eyes principle. For the quality assessment, the AMSTAR 2 tool was used. Results. We included eight systematic reviews out of 833 hits based on the prespecified inclusion criteria. The eight systematic reviews comprised ninety-nine primary studies that were also considered for the data analysis. Three systematic reviews were assessed as having a high risk of bias, while the others were rated with a moderate or low risk of bias. Most identified breast cancer risk prediction models showed a low prognostic quality. Adding breast density and genetic information as risk factors only moderately improved the models’ discriminatory accuracy. Conclusion. All breast cancer risk prediction models published to date show a limited ability to predict the individual breast cancer risk in women. Hence, it is too early to implement them in national breast cancer screening programs. Relevant randomised controlled trials about the benefit-harm ratio of risk-adjusted breast cancer screening programs compared to conventional age-based programs need to be awaited.

Background. Breast cancer with about 2.3 million diagnoses and 685,000 deaths globally is the most frequent malignancy in the female population. Continuous research has led to oncological and reconstructive advances in the management of breast cancer, thus improving outcomes and decreasing patient morbidity. Nowadays, the submuscular expander and prosthesis (E/P) implant-based breast reconstruction (IBR) accounts for 73% of all reconstructions. Despite its widely accepted efficacy, the technique is not free from complications and up to 28% of cases require revision surgery for mechanical complications such as capsular contracture, implant displacement/rotation, and implant rupture. With this study, the authors report their experience in the management of E/P IBR revision surgery through the technique of Selective Capsulotomies (SCs) and Partial Capsulectomy (PC). Methods. A retrospective study was conducted on patients who had previously undergone E/P IBR and presented for revision reconstruction between January 2013 and May 2023 at the Department of Plastic Surgery of the University of Siena, Italy. Reasons for revision included capsular contracture, implant displacement/rotation, and implant rupture. Revision reconstructions involved SC and PC with implant replacement. Fat grafting was also considered. The complication rate was evaluated by analysis of patients’ medical records. Patients’ satisfaction with the treatment was assessed through a specific questionnaire. Results. 32 patients underwent revision surgeries. No early complication occurred. Recurrence rate was assessed at 19% with average follow-up of 59 months (range: 13–114 months). The average time between revision surgery and recurrence was 3 years (range: 1–6 years). 23 patients answered the questionnaire and were overall satisfied with the treatments (8.29/10). Conclusions. SC possibly associated to PC is a valuable option for E/P IBR revision surgery with minimal complications, reduced surgical trauma, short operating time, and relatively low recurrence risk. In addition, treated patients are overall satisfied with the results over time.

Mammoplasty is a surgery commonly used for macromastia. Many mammoplasty techniques are described, all with their specific pros and cons. However, the concern to avoid serious complications sometimes takes precedence, and the ideal result cannot be. For macromastia and severely ptotic breasts, usually the free nipple-areolar complex (NAC) mammoplasty technique is implemented. The results, however, may only be completely satisfactory regarding cosmetics. Loss of NAC, poor appearance, flabbiness, flattening, and ptosis are among the disadvantages of this technique. This study aimed to present the results of mammoplasty employing the superomedial pedicle technique without interrupting a macromastia central base with a pedicle length of 8 to 18 cm. According to the literature, many plastic surgeons recommend the free NAC rather than the pedicle technique because of the high complication rates in mammoplasties planned for highly ptotic breasts and macromastia. On the other hand, many free NAC techniques and their modifications with pedicle mammoplasty are described. The general conviction is that a standard method, protocol, or technique good for all patients does not exist. Our results are more acceptable both cosmetically and physiologically. Therefore, the superomedial pedicle technique can be modified to achieve ideal results where free NAC mammoplasty is considered for severe macromastia and ptotic patients. This combined method contributes to the viability of NAC by increasing blood supply to breast tissue and providing an ideal breast appearance.

Idiopathic granulomatous mastitis (IGM) is a rare, benign inflammatory disorder of the breast that is often underrecognized. The exact etiology and pathophysiology are unknown, but milk stasis is felt to play a role. Classically, this condition is noninfectious, but many cases are noted to be associated with Corynebacterium species. Most patients affected are parous women with a mean age of 35, and many have breastfed within five years of diagnosis. Patients typically present with a painful mass and symptoms of inflammation, and these features can sometimes mimic breast cancer. Biopsy is needed to make a definitive diagnosis, and noncaseating granulomas are found on core biopsy. Many patients have a waxing and waning course over a period of six months to two years. Goal of treatment is to avoid surgery given poor wound healing, high risk of recurrence, and poor cosmetic outcomes. Medical treatment is preferred and includes observation, antibiotics, steroids, and immune modulators such as methotrexate. In more recent years, topical and intralesional steroids have become the treatment of choice, with similar outcomes to oral steroids.

Aim. To examine the clinical management of metaplastic breast cancer (MeBC), particularly the role of chemotherapy. Methods. This retrospective study included patients with MeBC (n = 73) from a tertiary breast cancer center: the “Centre des Maladies du Sein of the CHU de Québec–Université Laval.” The specimens were reviewed by two pathologists. Patient and tumor characteristics, systemic therapy (neoadjuvant and adjuvant), disease-free survival (DFS), and overall survival (OS) were recorded. Results. The median follow-up was 57.2 months. The mean tumor size was 39.5 ± 32.1 (range, 1–200) mm. Most were in grade 3 (75.3%), without evidence of clinical nodal involvement (75.3%), and triple-negative (79.5%). Chemotherapy was given to 49 (67.1%) patients. Thirty-seven patients (50.7%) underwent a mastectomy, and 22/37 (59.5%) received radiotherapy. Adjuvant chemotherapy was given to 36 patients (49.3%), and nine (12.3%) patients were treated with neoadjuvant chemotherapy. The 5-year OS and DFS rates were 60.2% and 66.8%. Among the nine patients who received neoadjuvant chemotherapy, three (33.3%) achieved a partial response, three (33.3%) had stable disease, and three (33.3%) had disease progression. The use of chemotherapy, especially in the adjuvant setting, had a significant positive effect on 5-year OS () and 5-year DFS (). Nodal involvement was associated with worse OS () but similar DFS (). Lumpectomy was associated with better 5-year OS () and DFS () compared with mastectomy. Conclusion. MeBC represents a rare heterogeneous group of malignancies with poor prognosis. Adjuvant chemotherapy was associated with improved OS and DFS. Patients should be carefully selected for neoadjuvant chemotherapy.
