The objective was to determine the 10-year oncological safety of nipple-sparing mastectomy (NSM) in patients diagnosed with ductal carcinoma in situ (DCIS). The use of NSM preserves the nipple-areola complex (NAC). As residual fibroglandular breast tissue can remain behind the spared NAC, its use for patient with breast cancer is controversial. The oncologic outcomes and complication rates after performing NSM compared to other techniques are still under debate and a concern when treating patients with breast cancer...

Yi Teng Fong, Chih-Hao Chen, Jyh-Ping Chen
By taking advantage of the pH-sensitive drug release property of graphene oxide (GO) after intracellular uptake, we prepared folic acid (FA)-conjugated GO (GOFA) for targeted delivery of the chemotherapeutic drug doxorubicin (DOX). GOFA-DOX was further encapsulated in an injectable in-situ forming thermo-sensitive hyaluronic acid-chitosan-g-poly(N-isopropylacrylamide) (HACPN) hydrogel for intratumoral delivery of DOX. As the degradation time of HACPN could be extended up to 3 weeks, intratumoral delivery of GOFA-DOX/HACPN could provide controlled and targeted delivery of DOX through slow degradation HACPN and subsequent cellular uptake of released GOFA-DOX by tumor cells through interactions of GOFA with folate receptors on the tumor cell's surface...

The latissimus dorsi myocutaneous flap (LDMF) is a reliable and frequently used option to bring vascularized skin and soft tissue to improve the stability and aesthetic result in breast reconstruction. Standard techniques with skin paddle inset in a horizontal or oblique fashion preferentially improve anterior projection (when inset at the mastectomy scar) or lower pole and infra-mammary fold (IMF) constriction (when inset into the IMF). Here, we describe a modification for inset of the LDMF that improves both anterior projection and lower pole/IMF constriction, while also allowing the latissimus muscle to fan out and provide complete implant coverage...

17β-Estradiol (E2) promotes metastasis of triple negative breast cancer cells to bone. Recent studies show many triple negative breast cancer cell lines lacking the 66 kDa estrogen receptor (ER) alpha (ERα66) or its splice variant ERα46, express another splice variant, ERα36 associated with membrane-mediated rapid actions of the hormone. qPCR and western blot confirmed that MCF7 cells possessed ERα splice variants ERα66, ERα46 and ERα36, while ER-negative breast cancer cells MDA-MB-231 possessed only ERα36...

Soft-tissue augmentation and implants are increasingly seen by the radiologist as more techniques emerge for a variety of indications and locations. Some surgical and implant procedures are performed for purely cosmetic reasons in otherwise healthy patients seeking to improve their body image, and some are performed for reconstruction after cancer or other chronic illnesses. Abdominoplasty, liposuction, and autologous fat grafting can be performed for abdominal and gluteal contouring. Injection of liquid injectable silicone has historically been fraught with legal issues, although it continues to be used for augmentation in a variety of anatomic locations...

Vascular endothelial growth factor receptor-2 is a dynamic target for therapeutic intervention in various types of cancers. This study was aimed to explore the anti-angiogenic activity of a novel vascular endothelial growth factor receptor-specific inhibitor named F16 in both in vitro and in vivo experimental models. This compound effectively reduced cell proliferation, tube formation, and migration of human umbilical vein endothelial cells in a concentration-dependent manner by directly inhibiting vascular endothelial growth factor binding and subsequent vascular endothelial growth factor receptor-2 phosphorylation...

BACKGROUND: Many mastopexy techniques have been described in the literature focusing on the new nipple areolar complex position and the breast deflation treatment, but only few of them detailed the glandular volume redistribution to avoid the use of implants. We describe a mastopexy procedure that brings the maximum of the volume to the central part of the breast. We compare the procedure to a "chignon" hair style way to vulgarize the technique and simplify its comprehension. METHODS: Breast volume is reshaped by the use of a vertical mastopexy and two deepithelized glandular flaps sutured for the first one to the pectoralis major fascia and for the second one to the contralateral flap...

INTRODUCTION: Implant-based breast reconstruction has relatively high complication rates. Removal of infected implants and immediate autologous reconstruction is a safe single-stage procedure that preserves the native breast skin envelope. METHODS: A single-centre, retrospective proof-of-concept review of all salvage procedures performed for acute/chronic infected or exposed implant-based reconstructions by a single surgeon over a 6-year period. RESULTS: We present 13 cases of a particularly difficult subgroup of acute/chronic infection/extrusion over a 6-year period...

The aim of the present study was to investigate changes in the expression of ErbBs during epithelial-mesenchymal transition (EMT) of breast cancer cells and its association with the expression of fatty acid synthase (FASN). MCF-7-MEK5 cells were used as the experimental model, while MCF-7 cells were used as a control. Tumor cells were implanted into nude mice for in vivo analysis. Cerulenin was used as a FASN inhibitor. Reverse transcription-polymerase chain reaction and western blot analysis were used to detect expression levels of FASN and ErbB1-4...

Background: Breast implants can be characterized by their fill material, surface texture, or shape. Whereas long-term good quality studies have provided evidence for the fill material and texture, there is still little consensus for choosing the shape of an implant. Surveys indicate that many surgeons choose only one implant shape, for reasons that may not always agree with outcomes from long-term studies. Objectives: We reviewed the first author's experience over the last six years with both round and anatomical implants, compared the rate of complications with either implant shape, and discussed the importance of keeping an open mind about using both implant shapes for primary breast augmentation...

Breast implant-associated anaplastic large-cell lymphoma (BIA-ALCL) is a rare peripheral T cell lymphoma. BIA-ALCL is a disease of the fibrous capsule surrounding the implant and occurs in patients after both breast reconstruction and augmentation. More than 300 cases have been reported so far, including two in a transgender patient. Here we describe BIA-ALCL presented with a mass in a transgender patient and the first case of BIA-ALCL in the Czech Republic. In 2007, a 33-year-old transgender male to female underwent bilateral breast augmentation as a part of his transformation to female...

BACKGROUND: Venous thromboembolism (VTE) remains a serious complication after the surgical treatment of breast cancer. Contemporary guidelines limit VTE chemoprophylaxis to the period of hospitalization. We conducted this study to evaluate the frequency of postdischarge VTE among surgically treated breast cancer patients and identify patient level factors associated with postdischarge VTE. METHODS: Using Arkansas, Florida, Nebraska, and New York state inpatient databases, we conducted a retrospective cohort study of adult women who underwent surgical treatment for breast cancer between October 1, 2008, and September 30, 2013...

Noonan syndrome (NS) is a relatively common genetic disorder with an autosomal dominant inheritance pattern affecting 1 in 1000-2500 births. Patients with this syndrome present with characteristic facial, musculoskeletal, cardiac and endocrine abnormalities. Lack of postpubertal breast development is a common manifestation of this syndrome and may result in severe hypomastia and a masculine appearance of the female chest. We report the first case of breast reconstruction in a 24-year-old woman with NS who lacked postpubertal breast development...

This article describes the use of implant-enhanced and total-autologous latissimus dorsi myocutaneous flaps in breast reconstruction. It addresses the indications for use of this reconstruction alternative, which have recently been expanded thanks to the advent of high-volume fat grafting. Given its straightforward dissection, reliable vascular pedicle, variety of approaches, and potential for excellent aesthetic results, use of latissimus dorsi flaps may be considered among first-line options in selected patients...
