Tumor-infiltrating lymphocytes and immune checkpoint proteins such as PD-L1 are potential prognostic factors and therapeutic targets in breast cancer. Most studies characterizing the breast tumor immune microenvironment have focused on ductal carcinomas. Here we investigate the tumor microenvironment of primary invasive lobular carcinomas. Previously constructed tissue microarrays of 47 lobular carcinomas were labeled by immunohistochemistry for PD-L1, CD8, CD20, and FoxP3. The stromal immune infiltrate density was qualitatively scored as a percentage of tumor area: 1+ (<5%); 2+ (5-10%); 3+ (10-15%); or 4+ (>50%)...

BACKGROUND: Invasive pleomorphic lobular carcinoma (IPLC) has been associated with a worse prognosis compared with classic invasive lobular carcinoma (cILC); however, studies are small and conflicting. We seek to examine the prognosis of women with IPLC compared with cILC. METHODS: A retrospective review of women with breast cancer at a single institution from 2003 to 2012 identified 193 women with invasive lobular carcinoma (ILC). IPLC was defined as ILC with a pathological description of primarily pleomorphic features and Nottingham histological grade score of 7, 8, or 9 or overall grade of 3 or mixed classic/pleomorphic features and overall grade of 3...

BACKGROUND: The aim of this study was the evaluation of breast MRI in determining the size and focality of invasive non-metastatic breast cancers. METHODS: The prospective, single-centre study conducted in 2015 compared preoperative MRI with histological analysis of mastectomy. RESULTS: One hundred one mastectomies from 98 patients were extensively analysed. The rates of false-positive and false-negative MRI were 2 and 4% respectively. The sensitivity of breast MRI was 84...

PURPOSE: Intraoperative frozen-section analysis of the lumpect-omy margin during breast-conserving surgery (BCS) is an excellent method in obtaining a clear resection margin. This study aimed to investigate the usefulness of intraoperative circumferential frozen-section analysis (IOCFS) of lumpectomy margin during BCS for breast cancer, and to find factors that increase the conversion into mastectomy. METHODS: From 2007 to 2011, 509 patients with breast cancer underwent IOCFS during BCS...

BACKGROUND: Re-excision after breast conserving surgery (BCS) for invasive breast cancer (IBC) can be omitted for focally positive margins in the Netherlands, but this guideline is not routinely followed. Focally positive and extensively positive margins have rarely been studied separately and compared to negative margins regarding clinicopathological predictors, residual disease incidence, and local recurrence. METHODS: All females with BCS for Tis-T3, without neo-adjuvant chemotherapy between 2005 and 2014 at one university hospital were included...

A female patient with oestrogen receptor-positive and human epidermal growth factor receptor 2 (HER2)-positive invasive lobular breast cancer presented with progressive disease on CT scan. Some days after initiation of antineoplastic chemotherapy and anti-HER2 targeted antibody therapy, the patient presented with profuse diarrhoea, neutropaenia, nausea and weakness. Although Clostridium difficile was rapidly tackled as a causative agent of gastrointestinal complaints, clinical situation did not markedly improve despite proper antimicrobial treatment...

A 61-year-old woman presented with a diagnosis of metastatic invasive lobular carcinoma of the right breast, and after treatment it had regressed or was stable except for a scalp nodule. When biopsied, the outer edges of the scalp lesion had findings consistent with breast carcinoma; however, the bulk of the tumor's pathology was consistent with melanoma. It appeared that most of the tumor was a highly vascularized melanoma with lobular breast carcinoma noted at its edges.

Invasive lobular carcinoma (ILC) of the breast is the second most common histologic subtype of breast cancer, representing 10% of breast cancer occurrences. It differs from invasive ductal carcinoma in its epidemiology, clinical and radiological presentation, associated molecular changes, and the natural course of disease. Often, ILC presents at an advanced stage of onset in postmenopausal women [1]. This article is protected by copyright. All rights reserved.

BACKGROUND: Breast-conservation surgery with radiotherapy is a treatment highly recommended by the guidelines from the National Comprehensive Cancer Network. However, several variables influence the final receipt of radiotherapy and it might not be administered to breast cancer patients. Our objective is to propose a systematic framework to identify the clinical and non-clinical variables that influence the receipt of unexpected radiotherapy treatment by means of Bayesian networks and a proposed heuristic approach...

Invasive lobular carcinoma (ILC) is the second most common breast cancer subtype and accounts for 8-14% of all cases. Although the majority of human ILCs are characterized by the functional loss of E-cadherin (encoded by CDH1), inactivation of Cdh1 does not predispose mice to develop mammary tumors, implying that mutations in additional genes are required for ILC formation in mice. To identify these genes, we performed an insertional mutagenesis screen using the Sleeping Beauty transposon system in mice with mammary-specific inactivation of Cdh1...

Metastasis from breast carcinoma to the gastrointestinal tract (GIT) is very uncommon. To date, only a few cases have been described worldwide. Of those which do metastasize to the GIT, only estrogen receptor (ER), progesterone receptor (PR) and HER2-neu receptor positive cancers have been reported and none have been mentioned in the U.S. We report a case of a 70-year-old white female with history of triple negative lobular carcinoma eight years earlier who presented with solitary jejunal mass causing obstruction...

PURPOSE: Invasive lobular carcinoma (ILC) of the breast has unique clinicopathologic characteristics, compared to invasive ductal carcinoma. The role of the 21-gene Recurrence Score (RS) has not been clearly defined for ILC. We sought to determine the prognostic value of RS and the impact of adjuvant chemotherapy on long-term survival in patients with ILC. METHODS: Utilizing the Surveillance, Epidemiology and End Results database from 2004 to 2013, we identified records of women aged 18-74 years, diagnosed with estrogen receptor (ER)-positive ILC (stage I to III) with RS available...

Preoperative contrast-enhanced (CE) breast magnetic resonance imaging (MRI) remains controversial in the newly diagnosed breast cancer patient. Additional lesions are frequently discovered in these patients with CE breast MRI. As staging and treatment planning evolve to include more information on tumor biology and aggression, so should our consideration of extent of disease. Directing CE breast MRI to those patients most likely to have additional disease may be beneficial. We sought to develop practical guidance for the use of preoperative CE breast MRI in the newly diagnosed breast cancer patient based on recent scientific data...

PURPOSE: Women with benign breast disease (BBD) have an increased risk of subsequent breast cancer. However, whether conventional breast cancer risk factors influence risk of breast cancer among women with BBD is unclear. In this study, we investigated the associations of lifestyle, menstrual/reproductive, and histological factors with risk of breast cancer among women biopsied for BBD. METHODS: We conducted a case-control study, nested within a cohort of 15,395 women biopsied for BBD at Kaiser Permanente Northwest between 1971 and 2006...

Comparing risk factor associations between invasive breast cancers and possible precursors may further understanding of factors related to initiation versus progression. Accordingly, among 190,325 postmenopausal participants in the National Institutes of Health-AARP Diet and Health Study (1995-2011), we compared risk factor associations between incident ductal carcinoma in situ (DCIS: n = 1,453) and invasive ductal carcinomas (n = 7,525) and lobular carcinoma in situ (LCIS: n = 186) and invasive lobular carcinomas (n = 1,191)...

INTRODUCTION: The intent of this analysis was to investigate and validate the prognostic potential of Ki67 in a multi-center series of patients affected by early stage 'pure' invasive lobular carcinoma (ILC). METHODS: Clinical-pathological data of patients affected by ILC were correlated with overall survival and disease-free survival (OS/DFS); data from a parallel invasive ductal carcinoma (IDC) patients' cohort were gathered as well. The maximally selected Log-Rank statistics analysis was applied to Ki67 continuous variable to estimate the appropriate cut-off...
