PURPOSE: The clinical behavior and outcome of multifocal (MF) and multicentric (MC) breast tumors are not well characterized. The purpose of this study was to compare the prognosis of MF/MC tumors with unifocal (UF)tumors and its correlation with other pathological characteristics and patient outcomes. METHODS: Eighty-three patients with MC/MF breast cancer and 501 with UF breast cancer treated at the Surgical Clinic Nis were studied. We compared MC/MF and UF breast cancer patients with respect to demographics, tumor characteristics- adjuvant systemic therapy, local recurrence-free survival (LRFS) and overall survival (OS)...

BACKGROUND: Biologic factors guide treatment decisions and have a significant impact on prognosis for breast cancer patients. This study was undertaken to develop a staging system incorporating biologic factors in addition to standard anatomic factors in the American Joint Committee on Cancer (AJCC) pathologic stage (PS) to assess disease-specific survival (DSS). METHODS: Overall, 3327 patients treated with surgery as an initial intervention at MD Anderson Cancer Center from 2007 to 2013 were identified...

The primary goal of a focal therapy treatment paradigm is to achieve cancer control through targeted tissue destruction while simultaneously limiting deleterious effects on peri-prostatic structures. Focal therapy approaches are employed in several oncologic treatment protocols, and have been shown to provide equivalent cancer control for malignancies such as breast cancer and renal cell carcinoma. Efforts to develop a focal therapy approach for prostate cancer have been challenged by several concepts including the multifocal nature of the disease and limited capability of prostate ultrasound and systematic biopsy to reliably localize the site(s) and aggressiveness of disease...

Epstein-Barr virus (EBV) is known to be associated with the development of malignant lymphoma and lymphoproliferative disorders (LPDs) in immunocompromised patients. EBV, a B-lymphotropic gamma-herpesvirus, causes infectious mononucleosis and oral hairy leukoplakia, as well as various pathological types of lymphoid malignancy. Furthermore, EBV is associated with epithelial malignancies such as nasopharyngeal carcinoma (NPC), salivary gland tumor, gastric carcinoma and breast carcinoma. In terms of oral disease, there have been several reports of EBV-related oral squamous cell carcinoma (OSCC) worldwide...

Glioma-associated oncogene 1 (Gli1) is a critical transcriptional factor of Sonic hedgehog pathway which has been proved to participate in the initiation and progression of tumor in mammalians. However, its clinical value in breast cancer remains unknown. Thus, a meta-analysis was performed to clarify the association of Gli1 over-expression, clinic-pathological characteristics, molecular subtypes and prognosis in breast cancer. According to included criteria, 13 eligible studies containing 2816 patients all around the world were selected in this study...

Importance: The GeparSixto trial provided evidence that the addition of neoadjuvant carboplatin to a regimen consisting of anthracycline, taxane, and bevacizumab increases pathological complete response (pCR) rates in patients with triple-negative breast cancer (TNBC). Whether BRCA1 and BRCA2 germline mutation status affects treatment outcome remains elusive. Objective: To determine whether BRCA1 and BRCA2 germline mutation status affects therapy response in patients with TNBC...

Expansion microscopy (ExM), a method for improving the resolution of light microscopy by physically expanding a specimen, has not been applied to clinical tissue samples. Here we report a clinically optimized form of ExM that supports nanoscale imaging of human tissue specimens that have been fixed with formalin, embedded in paraffin, stained with hematoxylin and eosin, and/or fresh frozen. The method, which we call expansion pathology (ExPath), converts clinical samples into an ExM-compatible state, then applies an ExM protocol with protein anchoring and mechanical homogenization steps optimized for clinical samples...

BACKGROUND: The tumor immune response is increasingly associated with better clinical outcomes in breast and other cancers. However, the evaluation of tumor-infiltrating lymphocytes (TILs) relies on histopathological measurements with limited accuracy and reproducibility. Here, we profiled DNA methylation markers to identify a methylation of TIL (MeTIL) signature that recapitulates TIL evaluations and their prognostic value for long-term outcomes in breast cancer (BC). METHODS: MeTIL signature scores were correlated with clinical endpoints reflecting overall or disease-free survival and a pathologic complete response to preoperative anthracycline therapy in 3 BC cohorts from the Jules Bordet Institute in Brussels and in other cancer types from The Cancer Genome Atlas...

PURPOSE: The presence of disseminated tumor cells (DTC) in the bone marrow of endometrial carcinoma patients has been demonstrated previously. In contrast to breast cancer, no prognostic significance or association with clinicopathological features was revealed for endometrial carcinoma so far. The aim of this study was to investigate DTC in a large patient cohort with in-depth pathology review data available and to study DTC occurrence in the context of L1CAM and long-term disease specific follow-up...

BACKGROUND: Breast cancer being a multifactorial disease, the role of infectious agent in development of disease is of great interest. The high incidence of breast cancer around the world has woken the interest in a viral etiology of breast cancer. Despite decades of research, no etiologic factor(s) for human breast cancer has been known and the quest for a contributing cause has all but been abandoned during the past years. Recent investigations have linked breast cancer to viral infections, such as Epstein-Barr virus (EBV), Human papillomavirus (HPV) and mouse mammary tumor virus...

REVIEW
Lizbeth Moira Kenny, Franco Orsi, Andreas Adam
Molecular profiling of metastatic disease may greatly influence the systemic therapy recommended by oncologists and chosen by patients, allowing treatment to be more targeted. Comprehensive care of patients with advanced breast cancer now includes percutaneous image-guided biopsy if this has the potential to influence systemic treatment [1]. Interventional radiologists can contribute significantly to the care of patients affected by breast cancer, in diagnostic and supportive procedures and importantly also in treatment...

INTRODUCTION: Ultrasound (US) is the imaging modality of choice for staging the axilla prior to surgery in patients with breast cancer (BC). High pathological complete response rates in the axilla after NACT mean a more conservative approach to surgery can be considered. Radiological re-staging is important in this decision making. After the presentation of results from ACOSOG Z1071 in December 2012, formal ultrasound re-assessment of the axilla after primary therapy was specifically requested in our institution...

PURPOSE: For women with a personal history of breast cancer (PHBC), no validated mechanisms exist to calculate future contralateral breast cancer (CBC) risk. The Manchester risk stratification guidelines were developed to evaluate CBC risk in women with a PHBC, primarily for surgical decision making. This tool may be informative for the use of MRI screening, as CBC risk is an assumed consideration for high-risk surveillance. METHODS: Three hundred twenty-two women with a PHBC were treated with unilateral surgery within our multidisciplinary breast clinic...

BACKGROUND: Nanoparticle albumin-bound paclitaxel (nab-Paclitaxel) is an alternative to standard taxanes for breast cancer (BC) treatment. We evaluated nab-Paclitaxel efficacy as neoadjuvant treatment for early estrogen receptor-positive (ER+), human epidermal growth factor receptor 2-negative (HER2-) disease. MATERIALS AND METHODS: Women with ER+, HER2-, stage II-III BC were treated preoperatively with four cycles of weekly nab-Paclitaxel (150 mg/m(2)), 3 weeks on and 1 week off...

BACKGROUND: The presence of tumor infiltrating lymphocytes (TIL) is associated with favorable prognosis. Recent evidence suggested that not only their density, but also the spatial organization as tertiary lymphoid structures (TLS), play a key role in determining patient survival. MATERIALS AND METHODS: In a cohort of 248 breast cancers, the clinicopathologic association and prognostic role of TLS was examined. RESULTS: Tertiary lymphoid structures were associated with higher tumor grade, apocrine phenotype, necrosis, extensive in situ component, lymphovascular invasion (LVI), and high TIL...

We report on a 56-year-old Caucasian female, diagnosed with locally advanced, hormone-receptor-positive, and human epidermal growth factor receptor 2 (HER2)-positive cancer of the left breast. The patient received neoadjuvant chemotherapy with adriamycin/cyclophosphamide (AC) followed by docetaxel/trastuzumab. A partial clinical and radiographical response was documented after four cycles of AC. Approximately one week after the first cycle of docetaxel and trastuzumab, the patient presented with diffuse edema, erythema, and induration involving the entire left breast...
