BACKGROUND: Breast augmentation is an elective surgery used to increase the size of the breast in females. This study was undertaken to determine the breast augmentation in Pakistani females. METHODS: From 2006 to 2011, 43 female patients who underwent breast augmentation via infra-mammary, periareolar, trans-umbilical and fat transfer were enrolled. For augmentation, saline-filled or gel-filled implants were used in the supine position under general anesthesia and local infiltration of adrenaline (1:100,000 dilution) on each side...

PURPOSE: Neoadjuvant chemotherapy (NACT) is increasingly used in breast cancer treatment. One of the main goals of NACT is to reduce the extent of local surgery of the breast and axilla. The aim of this study was to determine surgical outcomes for patients receiving breast-conserving therapy (BCT) after NACT, including margin status plus secondary surgeries, excision volumes, and cosmetic outcomes. METHODS: A systematic review was performed in accordance with PRISMA principles...

BACKGROUND: The prognosis of early breast cancer (EBC) depends on patient and tumor characteristics. The association between tumor size, the largest diameter in TNM staging, and prognosis is well recognized. According to TNM, tumors classified as T2, could have very different volumes; e.g. a tumor of 2.1 cm has a volume of 4500 mm3, while a tumor of 4.9 cm has a volume of 60.000 mm3 even belonging to the same class. The aim of the study is to establish if the prognostic role of tumor size, expressed as diameter and volume, has been overshadowed by other factors...

BACKGROUND: Over the past 40 years the Danish Breast Cancer Cooperative Group (DBCG) has made significant contributions to improve outcome and to make treatment of patients with early breast cancer more tolerable through nationwide and international trials evaluating loco-regional and systemic treatments. These trials have been instrumental to establish standards for the treatment of early breast cancer. METHODS: The DBCG 82 trials had a global impact by documenting that the significant gain in loco-regional recurrence from postmastectomy radiation added to systemic therapy was associated with a reduction in distant recurrence and mortality in high-risk pre- and postmenopausal patients...

Purpose: The GEC-ESTRO has reported the equivalent outcomes of partial breast irradiation (PBI) using multicatheter interstitial brachytherapy (MCB) to whole breast irradiation (WBI) in breast-conserving therapy (BCT). We performed single-stage BCT with partial breast brachytherapy by intraoperative catheter placement. After the categorization of patients into inclusion and exclusion criteria on this trial, our databases were evaluated in order to translate it to Japanese patients. Material and methods: Patients undergoing BCT were retrospectively examined between November 2007 and December 2015...

Ductal carcinoma in situ (DCIS) is a heterogeneous disease that has been investigated less extensively than invasive breast cancer. Women with DCIS are mainly treated with conservative surgery almost exclusively followed by radiotherapy. However, as radiation treatment is not always effective, the search for biomarkers capable of identifying DCIS lesions that could progress to invasive cancer is ongoing. Although conventional biomarkers have been thoroughly studied in invasive tumours, little is known about the role played by androgen receptor (AR), widely expressed in DCIS...

REVIEW
Hideko Yamauchi, Junko Takei
Hereditary breast and ovarian cancer (HBOC) syndrome represents 5-10% of all breast cancers. In Japan, the HBOC syndrome is frequently diagnosed in patients with breast cancer. Therefore, a treatment strategy combining a plan for existing breast cancer and for reduction of future breast and ovarian cancer risk is necessary. Breast cancer risk-reducing management involves three options-surveillance, chemoprevention, and risk-reducing mastectomy (RRM). RRM can prevent >90% of new breast cancers. Ovarian cancer risk management options are more limited, and risk-reduction salpingo-oophorectomy is the only option since there is no proven effective early detection method available...

INTRODUCTION: breast conserving therapy remains the first choice in breast cancer care for the early stages. Adequate surgical margins are essential to reduce the risk of locoregional recurrence. This study aims to identify risk factors of positive margins and locoregional recurrence. MATERIALS AND METHODS: 437 patients who underwent a lumpectomy for invasive breast carcinoma or ductal carcinoma in situ have been included. Age, surgical margins, size, type, grade and number of tumor foci, the presence of ductal carcinoma in situ, lymph node status, expression of hormone receptors and HER-2 gene were assessed as risk factors for positive margins and locoregional recurrence...

INTRODUCTION: Neoadjuvant endocrine treatment (NET) is a low-toxicity approach to achieve operability in locally advanced breast cancer, and to facilitate breast conservation in early breast cancer, particular in patients with highly estrogen receptor (ER) positive and HER2-negative disease. Here, we report the results obtained by neoadjuvant letrozole in patients with early breast cancer in a phase-II design. MATERIAL AND METHODS: A total of 119 postmenopausal women with ER-positive, HER2-negative operable breast cancer were assigned to four months of neoadjuvant letrozole before definitive surgery...

The non-receptor tyrosine kinase, PTK6/BRK, is highly expressed in multiple tumor types, including prostate, ovarian, and breast cancers, and regulates oncogenic phenotypes such as proliferation, migration, and survival. PTK6 inhibition also overcomes targeted therapy resistance of HER2+ breast cancer. Although PTK6 is highly expressed in ER+ Luminal breast cancers, the role of PTK6 in this subtype has not been elucidated. In this study, we investigated the functions of PTK6 in ER+ Luminal breast cancer cells, including those that are relatively resistant to estrogen deprivation or targeted endocrine therapies used in the treatment of ER+ cancers...

AIMS: Breast conserving surgery rates are affected by many factors including distance to radiotherapy and tumor-related features. Numerous studies have found women who must travel further for radiotherapy are more likely to choose mastectomy and avoid radiotherapy. We examined relationships between socioeconomic group, distance to radiotherapy services and mastectomy rates across a range of rural and metropolitan settings. METHODS: We used a dataset extracted from the Evaluation of Cancer Outcomes Barwon South Western Registry, which captured data on new breast cancer diagnoses in the southwest region of Victoria, Australia...

Mediator is a conserved, multi-subunit macromolecular machine divided structurally into head, middle, and tail modules, along with a transiently associating kinase module. Mediator functions as an integrator of transcriptional regulatory activity by interacting with DNA-bound transcription factors and with RNA polymerase II (Pol II) to both activate and repress gene expression. Mediator has been shown to affect multiple steps in transcription, including chromatin looping between enhancers and promoters, pre-initiation complex formation, transcriptional elongation, and mRNA splicing...

PURPOSE: To guide early stage breast cancer patients to choose between breast conserving surgery (BCS) and mastectomy (MST) considering the predicted cosmetic result and quality of life (QoL). METHODS: A decision model was built to compare QoL after BCS and MST. Treatment could result in BCS with good cosmesis, BCS with poor cosmesis, MST only, and MST with breast reconstruction. QoL for these treatment outcomes were obtained from a previous study and the literature and translated into EuroQoL-5D derived utilities...
