"Bifidus pedicle", The Use of Bilobed Superomedial Pedicle for Breast Reshaping Following Upper Outer Quadrantectomy: A New Oncoplastic Breast Surgery Technique.

INTRODUCTION: The aim of this work was to describe our technique, the "Bifidus pedicle", which is a modification of the superomedial pedicle, for managing large breast cancers (BCs) in the upper outer quadrant (UOQ) in patients with medium/large breasts and associated ptosis. Observed complications, cosmetic outcome and oncologic safety were also reported. MATERIALS AND METHODS: Thirty patients underwent our modification of the superomedial pedicle combined with a Wise skin resection pattern for large BCs in the UOQ. All patients underwent contralateral Wise pattern breast reduction/mastopexy for symmetry. RESULTS: The average weight of the quadrantectomy specimen was 235 grams (range: 36-400 grams). Mean free tumour margin was 19.4 mm (range: 16-30). Mean operative time was 165 minutes (range: 150-220). Eight (13.2%) breasts had minor complications: two partial NAC necrosis, and six minimal wound dehiscences. Mean follow-up was 22 months (range: 12-30). Overall satisfaction rate was 91%; patients reported to be satisfied the most with the shape (92%) of the breasts, the achieved symmetry (94%), and the volume (85%), focusing on the fullness in the UOQ. CONCLUSIONS: Our Bifidus pedicle allowed to fill even wide defects in the UOQ, because we selectively employed it in patients with medium to large ptotic breasts where the lower pole had enough tissue to be displaced. Satisfactory cosmetic and oncologic outcomes were achieved with low complication rate. LEVEL OF EVIDENCE IV: This journal requires that authors assign a level of evidence to each article.

Neoadjuvant endocrine therapy for luminal breast tumors: State of the art, challenges and future perspectives.

Neoadjuvant endocrine treatment (NET) associates to satisfactory rates of breast conservative surgery and conversions from inoperable to operable hormone receptor-positive (HR+)/HER2-negative breast cancer (BC), with less toxicities than neoadjuvant chemotherapy (NACT) and similar outcomes. Hence, it has been proposed as a logical alternative to NACT in patients with HR+/HER2- BC candidate to a neoadjuvant approach. Nevertheless, potential barriers to the widespread use of NET include the heterogeneous nature of patient response coupled with the long duration needed to achieve a clinical response. However, interest in NET has significantly increased in the last decade, owing to more in-depth investigation of several biomarkers for a more adequate patient selection and on-treatment benefit monitoring, such as PEPI score, Ki67 and genomic assays. This review is intended to describe the state-of-the-art regarding NET, its future perspectives and potential integration with molecular biomarkers for the optimal selection of patients, regimen and duration of (neo)adjuvant treatments.

Abdominal wall reconstruction for desmoid tumour surgery: Case report.

INTRODUCTION: Desmoid tumours are rare benign neoplasms with strong tendency to local invasion and recurrence. They usually rise from muscles and aponeurosis and could be challenging for medical treatment. We here report the case of a patient requiring the excision of part of the abdominal rectus muscle and an abdominal wall reconstruction. PRESENTATION OF CASE: A 38 years old women referred to our institution complaining of a painful lump in the anterior abdominal wall. She underwent ultrasonography (US), magnetic resonance imaging (MRI) and a computed tomography (CT) biopsy who showed the presence of a desmoid tumour arising in the right abdominal rectus muscle. She underwent surgical excision of the mass and an abdominal wall reconstruction according to the posterior component separation technique, with a large polypropylene mesh reinforcement. The post-operative period was uneventful and at 6 months she shows no clinical nor radiological recurrence. DISCUSSION: Desmoid tumours are rare neoplasms rising in many anatomical spaces and requiring challenging decisions. A radical resection with free margins remains the principal determinant of outcome. Non-surgical approaches and adjuvant therapy may be useful for patients with unresectable lesions. CONCLUSION: The optimal treatment strategy for desmoid tumours still remains unclear. A multidisciplinary approach is always the best strategy to establish the correct treatment.
