BACKGROUND: Leuprolide is a safe and effective treatment of estrogen receptor-positive premenopausal breast cancer. Data from the SOFT/TEXT trials solidified leuprolide in combination with an aromatase inhibitor as an effective hormonal treatment for premenopausal breast cancer. However, the efficacy of monthly leuprolide depot compared to leuprolide depot every 3 months in combination with an aromatase inhibitor in this patient population is unclear. PATIENTS AND METHODS: In this single center retrospective study, 201 patients were enrolled between January 1, 2015, and October 1, 2016; 100 were included in the 7...

Worldwide, various guidelines recommend what constitutes an adequate margin of excision for invasive breast cancer or for ductal carcinoma-in-situ (DCIS). We evaluated the use of different tumor resection margin guidelines and investigated their impact on positive margin rates (PMR) and reoperation rates (RR). Thirteen guidelines reporting on the extent of a positive margin were reviewed along with 31 studies, published between 2011 and 2016, reporting on a well-defined PMR. Studies were categorized according to the margin definition...

PURPOSE: To identify whether a certain group of breast ductal carcinoma-in-situ (DCIS) patients can be treated with breast-conserving surgery (BCS) alone; to analyze the clinicopathologic features of DCIS and tamoxifen administration in patients treated with BCS who developed ipsilateral breast tumor recurrence (IBTR). PATIENTS AND METHODS: Data for 375 women with breast DCIS who underwent BCS at our institute between June 2003 and October 2010 were analyzed. The patients were divided into different categories according to the recurrence risk predicted using the California/Van Nuys Prognostic Index (USC/VNPI) score (4-6, 7-9, and 10-12), Eastern Cooperative Oncology Group (ECOG) E5194 criteria, or combined risk features with USC/VNPI score and ECOG E5194 criteria...

BACKGROUND: Vascular endothelial growth factor (VEGF) has been shown to induce neurogenesis in the brain and yield neuroprotective effects. It is hypothesized that chemotherapy reduces circulating VEGF levels and leads to cognitive decline among patients. This multicenter longitudinal study aimed to evaluate the impact of chemotherapy on VEGF levels and the association between VEGF levels and cognitive function. PATIENTS AND METHODS: A total of 145 early-stage breast cancer patients were recruited and assessed before chemotherapy (T1), during chemotherapy (T2), and at the end of chemotherapy (T3)...

INTRODUCTION: Recently, Burstein et al identified 4 stable molecular subtypes of triple negative breast cancer (TNBC) by mRNA profiling: luminal androgen receptor (LAR), mesenchymal (MES), basal-like immune-activated (BLIA), and basal-like immune-suppressive (BLIS) types. The purpose of this study was to assess the feasibility of immunohistochemistry (IHC) surrogate panel in classifying the TNBC molecular subtypes using a large cohort of TNBC retrieved from a single institution. MATERIALS AND METHODS: IHC for androgen receptor [AR], claudin-3, E-cadherin, cytokeratin 5/6 [CK5/6], epidermal growth factor receptor [EGFR], indoleamine 2,3-dioxygenase 1 [IDO1], and Forkhead box C1 [FOXC1] were performed using the tissue microarray constructed from 200 TNBC samples...

BACKGROUND: Neoadjuvant systemic therapy (NST) is performed to increase the rate of breast-conserving surgery in advanced breast cancer patients. Although magnetic resonance imaging (MRI) is accurate in predicting residual cancer, if calcification remains, the issue of whether to perform the surgery on the basis of the residual tumor prediction range in mammography (MMG) or MRI has not yet been elucidated. This study aimed to estimate the accuracy of predicting residual tumor after NST for residual microcalcification on mammographic and enhancing lesion on MRI...

BACKGROUND: Cutaneous recurrence from breast cancer can pose a clinical challenge. It might be the only disease site, or could be part of disseminated disease, and often profoundly affects quality of life. Electrochemotherapy is a palliative treatment using electric pulses to locally permeabilize tumor cells and thereby significantly increase bleomycin cytotoxicity. Collaborating with the International Network for Sharing Practice on ElectroChemoTherapy (INSPECT), we consecutively and prospectively accrued data on patients treated with electrochemotherapy for cutaneous metastases from breast cancer...

This narrative literature review addresses the problem of an adnexal mass discovered during the course of breast cancer (BC) care, which may represent a benign condition, a metastatic process, or a primary ovarian cancer (OC), clinical scenarios associated with distinct physiopathology and prognosis. Furthermore, the coexistence of BC and OC in the same patient may be owing to a hereditary disorder, deserving specific management strategies and counseling. The initial detection and evaluation of an adnexal mass in a patient with BC requires a high index of suspicion, and the initial workup should include a thorough medical history and physical examination, measurement of tumor markers, complete blood count, and imaging tests...
