BACKGROUND: The Breast Lesion Excision System(®) (BLES(®)) is a stereotactic vacuum-assisted breast biopsy device that utilizes radiofrequency in order to excise non-palpable mammographic lesions for pathologic diagnosis. The purpose of this study was to evaluate the efficacy of BLES(®) in performing complete, margin-free excisions of small solid carcinomas. METHODS: Our retrospective study of prospectively enrolled patients included 50 cases of non-palpable, BIRADS ≥ 4, solid by means of mammography and sonography, lesions...

BACKGROUND: Neoadjuvant chemotherapy (NAC) is used to convert patients with inoperable locally advanced breast cancer (LABC) to operability, but has not traditionally been used to avoid mastectomy or axillary dissection in this subset. OBJECTIVE: The purpose of this study was to determine the rates of pathologic complete response (pCR) in LABC patients, and identify factors predictive of pCR to determine if responding patients might be suitable for limited surgery...

Polo-like kinases 1 (PLK1), a key regulator of mitosis, plays an essential role in maintaining genomic stability. Up-regulation of PLK1 was found in tumorigenesis and tumor progression of diverse cancers. However, the clinicopathological and prognostic implications of PLK1 in breast cancer (BC) have yet to be unveiled. Therefore, using PubMed, Web of Science, Embase, and Chinese databases, we conducted a meta-analysis to define the potential clinical value of PLK1 in BC. Eleven eligible articles with 2481 patients enrolled were included in the present meta-analysis, of which eight studies reported on the relationship between PLK1 expression and clinicopathological features, and nine studies provided survival data in BC patients...

BACKGROUND: It is controversial whether sentinel node biopsy (SNB) is adequate in breast cancer patients who become cN0 after primary chemotherapy. To address this we retrospectively compared outcomes in T2 cases given primary chemotherapy, comparing those given axillary dissection (AD) with those given SNB but no AD if sentinel nodes were clinically negative post-chemotherapy. METHODS: We examined overall survival (OS), disease-free survival (DFS), and axillary failure in 317 consecutive cT2 cN0/1 patients given primary chemotherapy followed by quadrantectomy/mastectomy, between January 2002 and December 2007...

Background: The role of tumor-infiltrating lymphocytes (TILs) in breast cancer has been extensively studied over the last decade. High TILs levels have been associated with pathological response rate in the neoadjuvant setting and with better outcomes in the adjuvant setting. However, little attention has been paid to changes in TILs and residual TIL levels after neoadjuvant chemotherapy (NAC). We investigated TIL levels before, after chemotherapy, and their dynamics during treatment; and we assessed the correlation of these levels with response to NAC and prognosis...

PURPOSE: The present study evaluated whether morphological-measured stromal and intra-tumour tumour-infiltrating lymphocytes (TILs) levels were associated with gene expression profiles, and whether TILs-associated genomic signature (GS) could be used to predict clinical outcomes and response to therapies in several breast cancer subtypes. METHODS: We retrospectively evaluated haematoxylin eosin (HE)-TILs levels and gene expression profiling data from 40 patients with primary breast cancer and extracted the 22 overexpressed genes in cases with high TILs scores as the TILs-GS...

The nuclear receptor (NR) superfamily contains hormone-inducible transcription factors that regulate many physiological and pathological processes through regulating gene expression. NR4A1 is an NR family member that still does not have an identified endogenous ligand, and its role in cancer is also currently unclear and controversial. In this study, we aimed to define the expression profiles and specific role of NR4A1 in the highly malignant triple-negative breast cancer (TNBC), which still lacks available targeted therapies...

INTRODUCTION: In locally and locally advanced triple-negative breast cancer (TNBC), neoadjuvant chemotherapy (NAC) only induces a pCR in 30-35% of patients. Clinical and pathological factors are not enough to distinguish the patients who have no chance of a pCR or not. The tumour microenvironment is critical for cancer and tumour-infiltrating lymphocytes (TIL). Moreover, the NAC scenario is the perfect setting to study possible changes in TIL levels. MATERIAL AND METHODS: Using our prospective maintained breast cancer (BC) database, we identified 164 TNBC patients treated with NAC between 1998 and 2015 with enough samples of diagnostic biopsy and after surgery...

BACKGROUND: Neoadjuvant-chemotherapy (NAC) is considered the standard treatment for locally advanced breast carcinomas. Accurate assessment of disease response is fundamental to increase the chances of successful breast-conserving surgery and to avoid local recurrence. The purpose of this study was to compare contrast-enhanced spectral mammography (CESM) and contrast-enhanced-MRI (MRI) in the evaluation of tumor response to NAC. METHODS: This prospective study was approved by the institutional review board and written informed consent was obtained...

BACKGROUND Diffuse idiopathic pulmonary neuroendocrine cell hyperplasia (DIPNECH) is a rare pulmonary disorder that is characterized by diffuse hyperplasia of bronchiolar and bronchial pulmonary neuroendocrine cells. In this condition, when no other pathological pulmonary condition is detected, DIPNECH is considered to be an idiopathic lung disease. DIPNECH is a rare condition that can be difficult to distinguish from other forms of reactive pulmonary neuroendocrine cell hyperplasia (NECH). We present a case of DIPNECH and describe the approach to diagnosis of this rare condition...

Sentinel lymph node biopsy has replaced axillary lymph node dissection in those patients with clinically node-negative axilla without compromising their oncologic outcomes. Indication of neoadjuvant chemotherapy has been extended to patients to evaluate the pathologic response and to offer more conservative breast surgery. Sentinel lymph node dissection after neoadjuvant chemotherapy is feasible and accurate in patients with clinically node-negative patients. The timing of the sentinel lymph node biopsy, before or after medical treatment has been studied with benefits for each procedure...

INTRODUCTION: Neoadjuvant chemotherapy (NAC) is the standard of care for locally advanced triple negative breast cancer, however, approximately 5% of cases show disease progression during NAC. Although downstaging is essential to create an opportunity for curative surgery and to improve the local control outcome in such a case, no additional line of chemotherapy has been established. CASE PRESENTATION: A 60-year-old woman was referred to our hospital for an axillary mass presenting three weeks ago and was diagnosed as having right locally advanced (T2N2M0, stage IIIA) triple negative breast cancer...

INTRODUCTION: Until now, no studies have investigated whether women other than those with dense breasts are suitable for adjunctive ultrasonography after negative mammography, and investigated whether all women with negative mammography are suitable for adjunctive ultrasonography. METHODS: Based on the Multi-modality Independent Screening Trial in China, a total of 31,918 women aged 45 to 65 years underwent both ultrasonography and mammography. Physicians performed ultrasonography and mammography separately and were blinded to each other's findings until their interpretations had been recorded...

Neuroendocrine breast carcinomas represent a rare subtype of breast cancer. Their definition, prevalence, and prognosis remain controversial in the literature. The 2012 WHO classification of breast cancer categorizes neuroendocrine carcinomas into three morphologically distinct subtypes: well-differentiated neuroendocrine tumors, poorly differentiated neuroendocrine carcinomas, and invasive breast carcinomas with neuroendocrine differentiation. We aimed to gain insight into the clinical, morphologic, phenotypic, and molecular features of 47 neuroendocrine breast carcinomas...

BACKGROUND: Bone represents one of the most common sites to which breast cancer cells metastasize. Patients experience skeletal related adverse events (pathological fractures, spinal cord compressions, and irradiation for deteriorated pain on bone) even during treatment with zoledronic acid (ZA). Therefore, we conducted a retrospective cohort study to investigate the predictive factors for symptomatic skeletal events (SSEs) in bone-metastasized breast cancer (b-MBC) patients. METHODS: We retrospectively collected data on b-MBC patients treated with ZA...

The present review deals with biomarker discovery, especially in regard to sample treatment via combinatorial peptide ligand libraries, perhaps the only technique at present allowing deep exploration of biological fluids and tissue extracts in search for low- to very-low-abundance proteins, which could possibly mark the onset of most pathologies. Early-stage biomarkers, in fact, might be the only way to detect the beginning of most diseases thus permitting proper intervention and care. The following cancers are reviewed, with lists of potential biomarkers suggested in various reports: hepatocellular carcinoma, ovarian cancer, breast cancer and pancreatic cancer, together with some other interesting applications...

BACKGROUND: Clinicians use clinical and pathological parameters, such as tumour size, grade and nodal status, to make decisions on adjuvant treatments for breast cancer. However, therapeutic decisions based on these features tend to vary due to their subjectivity. Computational and mathematical algorithms were developed using clinical outcome data from breast cancer registries, such as Adjuvant! Online and NHS PREDICT. More recently, assessments of molecular profiles have been applied in the development of better prognostic tools...
