Accurate inference of relatedness between individuals in breeding population contributes to the precision of genetic parameter estimates, effectiveness of inbreeding management and the amount of genetic progress delivered from breeding programs. Pedigree reconstruction has been proven to be an efficient tool to correct pedigree errors and recover hidden relatedness in open pollinated progeny tests but the method can be limited by the lack of parental genotypes and the high proportion of alien pollen from outside the breeding population...

A 43-year-old premenopausal female presented with a multicentric infiltrating lobular carcinoma of the left breast with axillary nodes metastasis. She underwent modified radical mastectomy with axillary lymph node dissection (level I and II) followed by a mixed autologous latissimus dorsi flap reconstruction with the addition of prosthesis. The final pathological analysis revealed a 6 cm invasive lobular carcinoma pT3N2aM0, grade III/III, estrogen and progesterone positive, human epidermal growth factor receptor 2 (HER2) negative, with 5/16 positive lymph nodes...

During High Dose Rate Brachytherapy (HDR-BT) the spatial position of the radiation source inside catheters implanted into a female breast is determined via electromagnetic tracking (EMT). Dwell positions and dwell times of the radiation source are established, relative to the patient's anatomy, from an initial X-ray-CT-image. During the irradiation treatment, catheter displacements can occur due to patient movements. The current study develops an automatic analysis tool of EMT data sets recorded with a solenoid sensor to assure concordance of the source movement with the treatment plan...

Diffuse optical breast imaging utilizes near-infrared (NIR) light propagation through tissues to assess the optical properties of tissues for the identification of abnormal tissue. This optical imaging approach is sensitive, cost-effective, and does not involve any ionizing radiation. However, the image reconstruction of diffuse optical tomography (DOT) is a nonlinear inverse problem and suffers from severe illposedness due to data noise, NIR light scattering, and measurement incompleteness. An image reconstruction method is proposed for the detection of breast cancer...

PURPOSE: The pedicled, descending-branch muscle-sparing latissimus dorsi (MSLD) flap has been widely used for breast reconstruction following total mastectomy. However, the superiority of the MSLD flap compared to the conventional latissimus dorsi (CLD) flap in preventing seroma formation has not been demonstrated. This study compares the morbidities related to seroma formation following pedicled MSLD flap and CLD flap breast reconstruction. METHODS: A total of 15 women who underwent partial mastectomy and immediate partial breast reconstruction with MSLD flaps were compared with 15 women under identical conditions with CLD flap breast reconstruction...

PURPOSE: Dynamic contrast enhanced magnetic resonance imaging (DCE-MRI) is used in cancer imaging to probe tumor vascular properties. Compressed sensing (CS) theory makes it possible to recover MR images from randomly undersampled k-space data using nonlinear recovery schemes. The purpose of this paper is to quantitatively evaluate common temporal sparsity-promoting regularizers for CS DCE-MRI of the breast. METHODS: We considered five ubiquitous temporal regularizers on 4...

BACKGROUND: Classic techniques of delayed prosthetic breast reconstruction use the mastectomy scar as an access route. As a result, the filling of the expander must be postponed until the wounds have healed. This creates an asymmetry between the breasts with the volume changes caused by the filling of the expander, which may occur over several weeks and cause considerable discomfort. METHODS: Delayed breast reconstruction was performed via the axillary incision made for sentinel lymph node biopsy or lymphadenectomy with endoscopic assistance and detachment of the pectoralis major muscle...

We present a case report on the successful healing of a Pseudomonas infection wound in a 52-year-old female with morbid obesity, noninsulin dependent diabetes mellitus and a history of tobacco use, who presented with Stage IIIA (T3, N2, Mo) infiltrating ductal carcinoma. The patient received neoadjuvant chemotherapy prior to her bilateral skin-sparing total mastectomies with right axillary sentinel lymphadenectomy. She also had staged reconstruction with temporary breast implants and plans for deep inferior epigastric perforator flaps...

Normal adult mammary stem cells (AMSCs) are promising sources for breast reconstruction, particularly following the resection of breast tumors. However, carcinogenic events can potentially convert normal AMSCs to cancer stem cells, posing a safety concern for the use of AMSCs for clinical tissue regeneration. In the present study, AMSCs and autologous primary breast cancer cells were isolated and compared for their ability to differentiate, their gene expression profile, and their potential to form tumors in vivo...

Stand-alone cone beam computed tomography (CT) and single-photon emission computed tomography (SPECT) systems capable of complex acquisition trajectories have previously been developed for breast imaging. Fully three-dimensional (3-D) motions of SPECT systems provide views into the chest wall and throughout the entire volume. The polar tilting capability of the CBCT system has shown improvement in sampling close to the chest wall, while eliminating cone beam artifacts. Here, a single hybrid SPECT-CT system, with each individual modality capable of independently traversing complex trajectories around a common pendant breast volume, was developed...

PURPOSE: The authors have developed a method to combine a patient-specific map of tissue structure and average dielectric properties with microwave tomography. The patient-specific map is acquired with radar-based techniques and serves as prior information for microwave tomography. The impact that the degree of structural detail included in this prior information has on image quality was reported in a previous investigation. The aim of the present study is to extend this previous work by identifying and quantifying the impact that errors in the prior information have on image quality, including the reconstruction of internal structures and lesions embedded in fibroglandular tissue...

PURPOSE: The authors investigate the impact that incremental increases in the level of detail of patient-specific prior information have on image quality and the convergence behavior of an inversion algorithm in the context of near-field microwave breast imaging. A methodology is presented that uses image quality measures to characterize the ability of the algorithm to reconstruct both internal structures and lesions embedded in fibroglandular tissue. The approach permits key aspects that impact the quality of reconstruction of these structures to be identified and quantified...

INTRODUCTION: Immediate breast reconstruction (IBR) improves the quality of life of patients who undergo mastectomy. The latissimus dorsi flap (LDF) method provides particularly good aesthetic results, but its tolerance to subsequent radiotherapy remains unclear. We thus sought to assess tolerance and esthetic results and satisfaction, as reported by patients who underwent IBR by LDF with or without subsequent radiotherapy. MATERIALS AND METHODS: We performed a retrospective case-control study in a population of women who were diagnosed with breast cancer between January 1999 and January 2014 and who had mastectomies with IBR by LDF without prostheses...

It is imperative to continue screening for breast cancer and/or detect tumor recurrence in patients after they have undergone breast augmentation or reconstruction. As there is an increasing role for both screening and diagnostic imaging of the post-operative breast, it is important for the radiologist to be familiar with the commonly performed surgical techniques in breast augmentation and reconstruction. Imaging of the augmented and reconstructed breast, as well as complications, will be reviewed with a focus on Magnetic Resonance Imaging (MRI)...

BACKGROUND: Reconstructive breast surgery has continued to evolve over the last decade with a key change being the adoption of acellular dermal matrices (ADMs) as an adjunct for implant-based procedures. This retrospective observational study assesses the effect of ADMs on post-mastectomy reconstructive practice performed in a single institution. METHODS: We conducted a review of all patients undergoing breast reconstruction at a University Teaching Hospital for an 18-month period before and after adopting ADMs...
