Breast reconstruction (BR) represents a suitable option for women who are not expected to require postmastectomy radiotherapy (PMRT). As recent evidence has led to an extension of the indications for PMRT, this has also appeared to increase the incidence of reconstructive complications. Nevertheless, in the USA at least, trends towards BR are changing. The frequency of immediate reconstruction continues to increase, even in the setting of PMRT. In immediate implant-based reconstruction, a staged approach is preferred...

BACKGROUND: Achieving optimal inferolateral coverage is critical to successful prosthetic breast reconstruction. Serratus anterior fascia (SF) elevation, a promising alternative to muscle flaps and acellular dermis (ADM), has not been rigorously studied. This study evaluates complication rates after mastectomy and immediate tissue expander (TE) coverage using SF, relative to other existing methods of reconstruction. METHODS: Retrospective review of consecutive patients undergoing mastectomy with immediate TE reconstruction over 10 years at 1 institution was performed...

Primary breast sarcoma, arising from connective tissue within the breast, is extremely rare, accounting for less than 1% of all primary breast malignancies and no more than 5% of all sarcomas. The rarity of this pathology limits most studies to case reports and small retrospective studies, which has led to a lack of consensus on the clinical management. We report a clinical case of a 52-year-old woman, perimenopausal, previously healthy, with regular breast surveillance, who presented with a large (>20 cm) and rapidly expanding hypervascularized tumor of the left breast developed over 10 days, with a very thin preulcerative skin over the last 4 days...

PURPOSE: As indications for regional nodal irradiation (RNI) for breast cancer have expanded, so too has scrutiny over potential late toxicity from radiotherapy. This emphasizes the need for careful radiation treatment planning to maximize the therapeutic ratio. We sought to evaluate how often unacceptable doses (UDs) to organs at risk (OARs) occur and the associated factors for patients receiving RNI in daily practice. METHODS AND MATERIALS: Treatment records of patients who received RNI from February 2012 to May 2015 were studied...

BACKGROUND: Postoperative infections following tissue expander-based breast reconstruction represent a significant threat to the reconstructive process. Studies have found the incidence to be as high as 29%. There has been abundant research into the risk factors associated with these infections, although very few studies have focused on the causative organisms. The purpose of this study was to investigate the bacterial flora associated with tissue expander infections after breast reconstruction...

OBJECTIVE: The goal of this literature review is to review and combine case studies of accidental burns to the breast, following mastectomy and immediate breast reconstruction with autologous tissue, implants, or tissue expanders. METHODS: The authors searched PubMed and Cochrane Library and reviewed cases of burns of reconstructed breasts after mastectomy from July 1985 to May 2015. Only studies in the English language were included in their search. They also report 5 new cases of burns in patients with burns to the breast, which were either reconstructed with implants or tissue expanders at Sheba Medical Center (Ramat Gan, Israel)...

PURPOSE: To model the magnetic port in the temporary breast tissue expanders and to improve accuracy of dose calculation in Pinnacle, a commercial treatment planning system (TPS). METHODS: A magnetic port in the tissue expander was modeled with a radiological measurement-basis; we have determined the dimension and the density of the model by film images and ion chamber measurement under the magnetic port, respectively. The model was then evaluated for various field sizes and photon energies by comparing depth dose values calculated by TPS (using our new model) and ion chamber measurement in a water tank...

PURPOSE: Mastectomy patients with breast reconstruction usually have a magnetic injection port inside the breast during radiation treatments. The magnet has a very high CT number and produces severe streaking artifact across the entire breast in CT images. Our routine strategy is to replace the artifact volumes with uniform water, and it is necessary to validate that the planned dose, with such an artifact correction, is sufficiently accurate. METHODS: A phantom was made with a gelatine-filled container sitting on a Matrixx detector, and the magnetic port was inserted into gelatine with specific depths and orientations...

BACKGROUND: Little is known about the influence of the underlying tissue as donor for nipple-areola complex (NAC) reconstruction. Also, there is a complete lack of knowledge about the fate of nipple volume. OBJECTIVES: The goal of this retrospective, single-institution study was to analyze a case series after nipple reconstruction using a multimodal evaluation including 3-dimensional (3D) laser scanner analyses. METHODS: Unilateral mastectomy patients after either expander-based or autologous breast reconstruction using the skate flap were included...

In prosthesis-based breast reconstruction, drains are used to prevent seroma formation and to reduce the risk of infection. However, prolonged drainage increases the risk of ascending infection. Although the volume often accepted for drain removal is ≤30 mL per day, the optimal timing to remove the drain for best clinical outcome remains controversial.We did a retrospective cohort study of 569 patients of prosthesis-based breast reconstruction with infection rate as the outcome variable; drain duration and last daily drainage volume as the main independent variables...

Importance: Patients with breast cancer (BrCa) brain metastases (BrM) have limited therapeutic options. A better understanding of molecular alterations acquired in BrM could identify clinically actionable metastatic dependencies. Objective: To determine whether there are intrinsic subtype differences between primary tumors and matched BrM and to uncover BrM-acquired alterations that are clinically actionable. Design, Setting, and Participants: In total, 20 cases of primary breast cancer tissue and resected BrM (10 estrogen receptor [ER]-negative and 10 ER-positive) from 2 academic institutions were included...

AlloDerm(®) (LifeCell Corp.; Brancburg, NJ) is an acellular dermal matrix (ADM) that serves as an immunologically inert scaffold in plastic surgery. In breast reconstruction, it is used as a filler for lumpectomy defects and can be used to create the inferolateral portion of the tissue expander pocket or implant pocket in postmastectomy patients. However, there are limited reports of the radiologic findings of AlloDerm(®) in patients who have undergone postmastectomy reconstruction. Familiarity with the imaging features of AlloDerm(®) is essential for correct diagnosis...

Cancer is the second leading cause of death in US after cardiovascular disease. Image-based computer-aided diagnosis can assist physicians to efficiently diagnose cancers in early stages. Existing computer-aided algorithms use hand-crafted features such as wavelet coefficients, co-occurrence matrix features, and recently, histogram of shearlet coefficients for classification of cancerous tissues and cells in images. These hand-crafted features often lack generalizability since every cancerous tissue and cell has a specific texture, structure, and shape...

INTRODUCTION: Phosphodiesterase 5 (PDE5) inhibitors (PDE5i) have been used clinically for the treatment of erectile dysfunction, acting on the nitric oxide/cyclic guanosine monophosphate (NO/cGMP) signaling pathway. Simultaneously, researchers have elucidated the roles that this pathway plays in the regulation of cell proliferation, tumor development, and progression. As a result, our knowledge of PDE5i and cancer biology has expanded and provides an integration that holds great promise for some, but concern for others...
