Abstract
To develop a deep learning (DL)-based algorithm to predict the presence of stromal invasion in breast cancer using digital breast tomosynthesis (DBT). Our institutional review board approved this retrospective study and waived the requirement for informed consent from the patients. Initially, 499 patients (mean age 50.5 years, age range, 29-90 years) who were referred to our hospital under the suspicion of breast cancer and who underwent DBT between March 1 and August 31, 2019, were enrolled in this study. Among the 499 patients, 140 who underwent surgery after being diagnosed with breast cancer were selected for the analysis. Based on the pathological reports, the 140 patients were classified into two groups: those with non-invasive cancer (n = 20) and those with invasive cancer (n = 120). VGG16, Resnet50, DenseNet121, and Xception architectures were used as DL models to differentiate non-invasive from invasive cancer. The diagnostic performance of the DL models was assessed based on the area under the receiver operating characteristic curve (AUC). The AUC for the four models were 0.56 [95% confidence intervals (95% CI) 0.49-0.62], 0.67 (95% CI 0.62-0.74), 0.71 (95% CI 0.65-0.75), and 0.75 (95% CI 0.69-0.81), respectively. Our proposed DL model trained on DBT images is useful for predicting the presence of stromal invasion in breast cancer.

Abstract
A Pleural effusion cytology is vital for treating metastatic breast cancer; however, concerns have arisen regarding the low accuracy and inter-observer variability in cytologic diagnosis. Although artificial intelligence-based image analysis has shown promise in cytopathology research, its application in diagnosing breast cancer in pleural fluid remains unexplored. To overcome these limitations, we evaluate the diagnostic accuracy of an artificial intelligence-based model using a large collection of cytopathological slides, to detect the malignant pleural effusion cytology associated with breast cancer. This study includes a total of 569 cytological slides of malignant pleural effusion of metastatic breast cancer from various institutions. We extracted 34,221 augmented image patches from whole-slide images and trained and validated a deep convolutional neural network model (DCNN) (Inception-ResNet-V2) with the images. Using this model, we classified 845 randomly selected patches, which were reviewed by three pathologists to compare their accuracy. The DCNN model outperforms the pathologists by demonstrating higher accuracy, sensitivity, and specificity compared to the pathologists (81.1% vs. 68.7%, 95.0% vs. 72.5%, and 98.6% vs. 88.9%, respectively). The pathologists reviewed the discordant cases of DCNN. After re-examination, the average accuracy, sensitivity, and specificity of the pathologists improved to 87.9, 80.2, and 95.7%, respectively. This study shows that DCNN can accurately diagnose malignant pleural effusion cytology in breast cancer and has the potential to support pathologists.

Abstract
Traditionally, lymphovascular invasion (LVI) has represented one of the foremost pathological features of malignancy and has been associated with a worse prognosis in different cancers, including breast carcinoma. According to the most updated reporting protocols, the assessment of LVI is required in the pathology report of breast cancer surgical specimens. Importantly, strict histological criteria should be followed for LVI assessment, which nevertheless is encumbered by inconsistency in interpretation among pathologists, leading to significant interobserver variability and scarce reproducibility. Current guidelines for breast cancer indicate biological factors as the main determinants of oncological and radiation therapy, together with TNM staging and age. In clinical practice, the widespread use of genomic assays as a decision-making tool for hormone receptor-positive, HER2-negative breast cancer and the subsequent availability of a reliable prognostic predictor have likely scaled back interest in LVI's predictive value. However, in selected cases, the presence of LVI impacts adjuvant therapy. This review summarizes current knowledge on LVI in breast cancer with regard to definition, histopathological assessment, its biological understanding, clinicopathological association, and therapeutic implications.

Abstract
Cytokeratin 13 (CK13) is a type I acidic low molecular weight cytokeratin, which is mainly expressed in urothelium and in the squamous epithelium of various sites of origin. Loss of CK13 has been implicated in the development and progression of squamous epithelial neoplasms. To comprehensively determine CK13 expression in normal and neoplastic tissues, a tissue microarray containing 10,439 samples from 131 different tumor types and subtypes as well as 608 samples of 76 different normal tissue types was analyzed by immunohistochemistry. CK13 immunostaining was detectable in 42 (32.1%) of the 131 tumor categories including 24 (18.3%) tumor types with at least one strongly positive case. The highest rate of positive staining was found in various urothelial neoplasms (52.1-92.3%) including Brenner tumor of the ovary (86.8%) and in squamous cell carcinomas from various sites of origin (39.1-77.6%), Warthin tumors of parotid glands (66.7%), adenosquamous carcinomas of the cervix (33.3%), thymomas (16.0%), and endometroid carcinomas of the ovary (15.3%). Twenty other epithelial or germ cell neoplasms showed - a usually weak - CK13 positivity in less than 15% of the cases. In bladder cancer, reduced CK13 expression was linked to high grade and advanced stage (p < 0.0001 each). In squamous cell carcinoma of the cervix, reduced CK13 immunostaining was related to high grade (p = 0.0295) and shortened recurrence-free (p = 0.0094) and overall survival (p = 0.0274). In a combined analysis of 1,151 squamous cell carcinomas from 11 different sites of origin, reduced CK13 staining was linked to high grade (p = 0.0050). Our data provide a comprehensive overview on CK13 expression in normal and neoplastic human tissues. CK13 expression predominates in urothelial neoplasms and in squamous cell carcinomas of different organs, and a loss of CK13 expression is associated with aggressive disease in these tumors.

Abstract
O câncer de mama é o câncer de maior incidência entre as mulheres e o que apresenta a maior taxa de mortalidade no Brasil. Ele se localiza mais freqüentemente no quadrante superior externo da mama e em cerca de 13% é multicêntrico, o que é mais comum entre os carcinomas lobulares e entre as mulheres que têm história familiar. Apesar da palpação ser o método mais simples para o diagnóstico, somente cerca de 60% dos cânceres detectados por mamografia são palpáveis. O exame anatomopatológico é imprescindível para o diagnóstico do tumor primário e das metástases e para a classificação e o estadiamento. Os tumores malignos próprios da mama, isto é, os adenocarcinomas, são divididos em in situ e invasores e estes dois subgrupos, por sua vez, são divididos em ductais e lobulares. Cada um destes subgrupos tem seus subtipos, cada qual com suas características histopatológicas próprias que influenciam o comportamento clínico. Dentre os carcinomas ductais in situ, chama atenção o tipo comedocarcinoma que pode atingir grandes dimensões e se tornar palpável. Estes tumores são de alto grau nuclear e podem se tornar invasores precocemente. O carcinoma ductal infiltrante (GDI) clássico, além de tipo de tumor maligno mais comum da mama, é também o de pior prognóstico, principalmente aqueles de alto grau histológico. O carcinoma lobular infiltrante é o segundo tipo mais freqüente, tendo um prognóstico ser o um pouco melhor que o CDI.

Abstract
Invasive lobular breast carcinomas (ILC) account for approximately 15% of breast cancer diagnoses. They can be difficult to diagnose both clinically and radiologically, due to their infiltrative growth pattern. The pattern of metastasis of ILC is unusual, with spread to the serosal surfaces (pleura and peritoneum), retroperitoneum and gastrointestinal (GI)/genitourinary (GU) tracts and a higher rate of leptomeningeal spread than IDC. Routine staging and response assessment with computed tomography (CT) can be undertaken quickly and measurements can be reproduced easily, but this is challenging with metastatic ILC as bone-only/bone-predominant patterns are frequently seen and assessment of the disease status is limited in these scenarios. Functional imaging such as whole-body MRI (WBMRI) allows the assessment of bone and soft tissue disease by providing functional information related to differences in cellular density between malignant and benign tissues. A number of recent studies have shown that WBMRI can detect additional sites of disease in metastatic breast cancer (MBC), resulting in a change in systemic anti-cancer therapy. Although WBMRI and fluorodeoxyglucose-positron-emission tomography-computed tomography (FDG-PET/CT) have a comparable performance in the assessment of MBC, WBMRI can be particularly valuable as a proportion of ILC are non-FDG-avid, resulting in the underestimation of the disease extent. In this review, we explore the added value of WBMRI in the evaluation of metastatic ILC and compare it with other imaging modalities such as CT and FDG-PET/CT. We also discuss the spectrum of WBMRI findings of the different metastatic sites of ILC with CT and FDG-PET/CT correlation. KEY POINTS: • ILC has an unusual pattern of spread compared to IDC, with metastases to the peritoneum, retroperitoneum and GI and GU tracts, but the bones and liver are the commonest sites. • WBMRI allows functional assessment of metastatic disease, particularly in bone-only and bone-predominant metastatic cancers such as ILC where evaluation with CT can be challenging and limited. • WBMRI can detect more sites of disease compared with CT, can reveal disease progression earlier and provides the opportunity to change ineffective systemic treatment sooner.

Abstract
BACKGROUND Due to the lack of high-level data, there is still controversy over the oncological safety of breast conservation in patients with centrally located breast cancer. This study aimed to assess the safety of breast-conserving surgery in patients with centrally located breast cancer based on the data from the Surveillance, Epidemiology, and End Results (SEER) database. METHODS We collected data for all cases diagnosed with breast cancer who underwent breast-conserving surgery from 2012-2014 in the SEER database. The primary outcome of our study was disease-specific survival (DSS) and overall survival (OS). The PSM was used to eliminate the effects of non-random statistics. Chi-square test, Kaplan-Meier method and Cox proportional hazards regression model on univariate and multivariate analysis were used to analyze the data. RESULTS Data from 79,214 patients who had undergone breast-conserving surgery were analyzed in this study, including those with breast cancer in the central region (n=3,128) and outside the central region (n=76,086). The DSS of central breast cancer patients and outside the central breast cancer patients was 58.1 months versus 58.0 months (P>0.05), respectively, while the OS of the 2 groups was 58.0 months versus 58.0 months (P>0.05), respectively. CONCLUSIONS Breast cancer in the central region should not be contraindicated for breast conserving surgery and breast-conserving surgery can benefit a wider range of patients.

Abstract
OBJECTIVES Dermal lymphatic invasion (DLI) with tumor emboli is a common pathologic characteristic of inflammatory breast cancer (IBC), although its presence is not required for diagnosis. We examined whether documented DLI on skin biopsy was associated with survival and time to recurrence or progression in IBC. MATERIALS AND METHODS A total of 340 women enrolled in the IBC Registry at Dana-Farber Cancer Institute between 1997 and 2019 were included in this study. Kaplan-Meier curves and multivariable Cox proportional hazards models were used to estimate hazard ratios and 95% confidence intervals for associations of DLI and overall survival, time to locoregional recurrence/progression, and distant metastasis by stage at presentation. RESULTS DLI was detected in 215 (63.2%) of IBC cases overall. At disease presentation, IBC with DLI had a higher prevalence of de novo metastases (37.7% vs. 26.4%), breast skin ulceration (6.1% vs. 2.4%), and lymphovascular invasion within the breast parenchyma (52.9% vs. 25.5%) and a lower prevalence of palpable breast mass (48.2% vs. 70.6%) than IBC without DLI. Over a median follow-up of 2.0 years, 147 deaths occurred. DLI was not associated with survival or recurrence in multivariable models (all P ≥0.10). For example, among women with stage III disease, hazard ratios (95% confidence intervals) for DLI presence was 1.29 (0.77-2.15) for overall survival, 1.29 (0.56-3.00) for locoregional recurrence, and 1.71 (0.97-3.02) for distant metastasis. CONCLUSION Although the extent of tumor emboli in dermal lymphatics may be associated with biological features of IBC, DLI was not an independent prognostic marker of clinical outcomes in this study.

Abstract
Background Two conflicting hypotheses as to how breast cancer (BC) accesses the systemic circulation dominated the 20th century and affected surgical treatment. We hypothesized that tumor lymphovascular invasion (LVI) at the primary tumor site favors lymphatic and not blood vessel, capillaries, and systemic metastases (Smets) are dependent upon regional lymph node (RLN) mets. Methods Data from BC patients undergoing RLN biopsy was professionally abstracted and maintained in a prospective, precisely managed, single-institution database. Associations of RLN, LVI, and Smets were estimated by univariate and multivariate backward logistic regression models and patient-affiliated demographic, clinicopathologic, treatment type, and molecular marker data. Results Of 3329 patients, followed 1–22 years (mean 7.8), 463 of 3329 (13.9%) showed LVI, 742 of 3329 (22.3%) had RLN mets, and 262 of 3329 (7.9%) had Smets. Smets occurred in 52 of 252 (21% with LVI+/RLN+); 116 of 2301 (5% with LVI−/RLN−); 65 of 465 (14% with LVI−/RLN+); and 17 of 207 (8% with LVI+/RLN−), p = 0.021 for association between LVI and Smets for RLN+ patients but not for RLN− patients (p = 0.051). Positive RLN, larger tumor size, and higher grade (all p < 0.001) were predictive of Smets by the multivariable model, whereas positive LVI was not. Conclusions LVI predicts RLN mets in BC. RLN is critical to Smets from BC, whereas LVI on its own is not. Smets occur significantly more commonly when both LVI and RLN mets occur together. LVI is, thus, likely to be primarily lymphatic invasion, and rarely, blood vessel invasion, supporting the Halsted paradigm. LVI and RLN together predict clinical outcome better than either alone.

Abstract
The detection of the region of interests (ROIs) on Whole Slide Images (WSIs) is one of the primary steps in computer-aided cancer diagnosis and grading. Early and accurate identification of invasive cancer regions in WSI is critical in the improvement of breast cancer diagnosis and further improvements in patient survival rates. However, invasive cancer ROI segmentation is a challenging task on WSI because of the low contrast of invasive cancer cells and their high similarity in terms of appearance, to non-invasive regions. In this paper, we propose a CNN based architecture for generating ROIs through segmentation. The network tackles the constraints of data-driven learning and working with very low-resolution WSI data in the detection of invasive breast cancer. Our proposed approach is based on transfer learning and the use of dilated convolutions. We propose a highly modified version of U-Net based auto-encoder, which takes as input an entire WSI with a resolution of 320×320. The network was trained on low-resolution WSI from four different data cohorts and has been tested for inter as well as intra- dataset variance. The proposed architecture shows significant improvements in terms of accuracy for the detection of invasive breast cancer regions.

Grading Ductal Carcinoma In Situ (DCIS) of the Breast - What's Wrong with It? Pathol Oncol Res 2019; 26:665-671.

Abstract
Ductal carcinoma in situ of the breast is a non-obligate precursor of invasive breast cancer, and at its lower risk end might not need treatment, a hypothesis tested in several currently running randomized clinical trials. This review describes the heterogeneity of grading ductal carcinoma in situ (DCIS). First it considers differences between low and high grade DCIS, and then it looks at several grading schemes and highlights how different these are, not only in the features considered for defining a given grade but also in their wording of a given variable seen in the grade in question. Rather than being fully comprehensive, the review aims to illustrate the inconsistencies. Reproducibility studies on grading mostly suggestive of moderate agreement on DCIS differentiation are also illustrated. The need for a well structured, more uniform and widely accepted language for grading DCIS is urged to avoid misunderstanding based misclassifications and improper treatment selection.

Abstract
PURPOSE Ductal carcinoma in situ (DCIS) of the breast is often regarded as a non-obligate precursor to invasive breast carcinoma but current diagnostic tools are unable to accurately predict the invasive potential of DCIS. Infiltration of immune cells into the tumour and its microenvironment is often an early event at the site of tumourigenesis. These immune infiltrates may be potential predictive and/or prognostic biomarkers for DCIS. This review aims to discuss recent findings pertaining to the potential prognostic significance of immune infiltrates as well as their evaluation in DCIS. METHODS A literature search on PubMed was conducted up to 28th January 2019. Search terms used were "DCIS", "ductal carcinoma in situ", "immune", "immunology", "TIL", "TIL assessment", and "tumour-infiltrating lymphocyte". Search filters for "Most Recent" and "English" were applied. Information from published papers related to the research topic were synthesised and summarised for this review. RESULTS Studies have revealed that immune infiltrates play a role in the biology and microenvironment of DCIS, as well as treatment response. There is currently no consensus on the evaluation of TILs in DCIS for clinical application. CONCLUSIONS This review highlights the recent findings on the potential influence and prognostic value of immunological processes on DCIS progression, as well as the evaluation of TILs in DCIS. Further characterisation of the immune milieu of DCIS is recommended to better understand the immune response in DCIS progression and recurrence.

Abstract
An understanding of prognostic factors in breast cancer is imperative for guiding patient care. Increased tumor size and more advanced nodal status are established independent prognostic factors of poor outcomes and are incorporated into the American Joint Committee on Cancer (AJCC) TNM (primary tumor, regional lymph node, distant metastasis) staging system. However, other factors including imaging findings, histologic evaluation results, and molecular findings can have a direct effect on a patient's prognosis, including risk of recurrence and relative survival. Several microarray panels for gene profiling of tumors are approved by the U.S. Food and Drug Administration and endorsed by the American Society of Clinical Oncology. This article highlights prognostic factors currently in use for individualizing and guiding breast cancer therapy and is divided into four sections. The first section addresses patient considerations, in which modifiable and nonmodifiable prognostic factors including age, race and ethnicity, and lifestyle factors are discussed. The second part is focused on imaging considerations such as multicentric and/or multifocal disease, an extensive intraductal component, and skin or chest wall involvement and their effect on treatment and prognosis. The third section is about histopathologic findings such as the grade and presence of lymphovascular invasion. Last, tumor biomarkers and tumor biology are discussed, namely hormone receptors, proliferative markers, and categorization of tumors into four recognized molecular subtypes including luminal A, luminal B, human epidermal growth factor receptor 2-enriched, and triple-negative tumors. By understanding the clinical effect of these prognostic factors, radiologists, along with a multidisciplinary team, can use these tools to achieve individualized patient care and to improve patient outcomes. ©RSNA, 2018.

Abstract
Cases in in situ and infiltrating lobular carcinoma of the breast reported in the Third National Cancer Survey were reviewed according to age, sex, race, and geographic distribution. The age-specific incidence rates indicate that there are two peak age periods of risk for invasive lobular carcinoma, the first occurring in ages 40-50 years and the second after age 65. The incidence rates for lobular carcinoma were compared to the incidence rates for intraductal and infiltrating ductal carcinoma reported from the Third National Cancer Survey and for total breast cancer from the Miyagi prefecture in Japan. These comparisons indicate that factors which influence the geographic variation in breast cancer play important roles in the etiology of infiltrating ductal carcinoma, but may have little effect upon the incidence of lobular carcinoma and intraductal carcinoma. The limitations of large histological epidemiological surveys are discussed.

Abstract
Measurements of cell cycle kinetics have been found to correlate with the clinical course of patients with breast cancer. However, the thymidine labeling index and more rapid methods like flow cytometry remain complicated and costly. We assessed cell proliferation of 67 breast carcinomas by an immunoperoxidase procedure using a monoclonal antibody, Ki-67, which reacts with a nuclear antigen in proliferating cells. The percentage of Ki-67 positive cells ranged from 2% to 70 %. Tumors with high mitotic rate, high nuclear grade, high histologic grade, and negative estrogen receptors had statistically higher Ki-67 labeling rates. We found no significant differences between the Ki-67 labeling rate and other clinical (age at diagnosis, menopausal status) or pathologic (necrosis, fibrosis, vascular invasion, lymphatic invasion, cellular reaction, tumor size, lymph node metastases) features assessed. These results parallel previously reported data, and confirm that this immunohistochemical staining of breast carcinoma by Ki-67 monoclonal antibody can be considered a rapid and convenient method for assessing cell cycle kinetics. However, further studies, evaluating the correlation between Ki-67 labeling rate and prognosis are needed to better define the real usefulness of this analysis in clinical practice.

Abstract
In fifty non selected ductal carcinomas of the breast we found that a marked tumoral inflammatory infiltrate (P < 0.025), perinodal tumoral infiltrate (P < 0.01), sinus catarrh (P < 0.05), follicular hyperplasia (P < 0.025), mixed pattern in lymph nodes (P < 0.01) and with 54 years of age or younger (P < 0.01) correlated significantly with lymph node metastases and/or high histologic grade. On the contrary, elastosis (P < 0.05), scanty or absent inflammatory infiltrate (P < 0.01), sinus histiocytosis (P < 0.001) and endothelial hyperplasia were statistically related to low histologic grade and/or lack of metastases. Elastosis is considered a defensive host response. Groups of lymphocytes in the perinodal fat is usually found in metastasized lymph nodes and may indicate metastasis should be sought in a lymph node which otherwise seems to be tumor-free.

Abstract
Diagnostic delay in a group of 189 women with breast cancer was studied and correlated with first symptom, stage of disease, histologic grade and prognosis. Diagnostic delay was divided into patient delay (time from the patient's discovery of a symptom to the first medical consultation) and system delay (time from medical diagnosis to treatment). Patients were divided into five groups by patient-delay time: 0 to 30 days; 31 to 90 days; 91 to 180 days; 181 to 365 days; and > 365 days. The median diagnostic delay was 60 days (range, 4-980) and was not influenced by patient age, marital status or nature of first symptom. A consistent and direct relationship was found between delay and tumor size, nodal involvement, presence of metastases, and histologic grade of disease at diagnosis. No correlation was found between diagnostic delay and histologic type distribution. The three-year survival rate after treatment was significantly lower for patients with a longer delay. Our data indicate that diagnostic delay appears to be an important determinant of stage at diagnosis in women with breast cancer and that it has an important influence on survival. In most cases, delay was mainly patient dependent (60 days); the median system-dependent delay was 15 days (range, 4-47). Since early treatment is generally accepted to be one of the most important determinants of prognosis in breast cancer patients, a reduction in diagnostic delay may lengthen survival time.

Abstract
The degree of productive fibrosis, amount of lymphoid infiltrate and nuclear grade have been studied in 492 consecutive cases of duct-infiltrating breast cancer. It has been found that highly significant relationships exist between these morphologic parameters of breast cancer: lymphoid infiltrate is directly related to nuclear anaplasia and antagonized by productive fibrosis; conversely, productive fibrosis is inversely related to nuclear anaplasia and antagonized by lymphoid infiltrate. Significant inverse relationships between productive fibrosis and lymphoid infiltrate persist in tumors that have the same nuclear grade. It is suggested that lymphoid infiltrate and productive fibrosis are suitable candidates as morphologic markers to estimate the age of breast cancer, while the nuclear grade is a suitable tool to identify subgroups with different behavior in the NOS (not otherwise specified) category of breast cancer.

Abstract
The presence of mammary lobules around overt cancer and the amount and the type of intraductal tumor component (solid, comedo, cribrous, comedo-cribrous, papillary) were defined in 493 consecutive cases of infiltrating human breast cancer to analyze the association of these parameters with other morphologic parameters, such as productive fibrosis, lymphoid infiltrate and nuclear grade. Data showed a significant inverse relationship between degree of intraductal component and productive fibrosis (p < 0.01) and direct relationships between a) presence of lobules and degree of intraductal component (p < 0.02) and b) intraductal component of comedo type and lymphoid infiltrate (p < 0.02). In addition, marked though not significant associations were observed between a) absence of lobules and intraductal component of papillary type (p < 0.10) and b) nuclear grade 1 and intraductal component of the comedo type (p < 0.10). Data suggest that cancers with a high degree of introductal component could have a lobular origin and papillary cancer could have a ductal origin. The other relationships observed might be useful in the subclassification of NOS (not otherwise specified) breast cancer.

The histologie epidemiology of all breast cancer cases that had been diagnosed in the Padua area over an 11-year period was studied, and the absolute and relative distribution of breast cancer, location indices according to histologic types, 5-yr distribution and annual age-specific incidences of infiltrating and noninfiltrating cancers, as well as noncancerous disease were calculated. The results suggest that the Padua area should be considered a medium-high risk area along with England and Scandinavia.

Abstract
Patients with triple negative breast cancer (TNBC) have no successful "targeted" treatment modality, which represents a priority for novel therapy strategies. Upregulated death receptor 5 (DR5) expression levels in breast cancer cells compared to normal cells enable TRA-8, a DR5 specific agonistic antibody, to specifically target malignant cells for apoptosis without inducing normal hepatocyte apoptosis. Drug resistance is a common obstacle in TRAIL-based therapy for TNBC. Calmodulin (CaM) is overexpressed in breast cancer. In this study, we characterized the novel function of CaM antagonist in enhancing TRA-8 induced cytotoxicity in TRA-8 resistant TNBC cells and its underlying molecular mechanisms. Results demonstrated that CaM antagonist(s) enhanced TRA-8 induced cytotoxicity in a concentration and time-dependent manner for TRA-8 resistant TNBC cells. CaM directly bound to DR5 in a Ca2+ dependent manner, and CaM siRNA promoted DR5 recruitment of FADD and caspase-8 for DISC formation and TRA-8 activated caspase cleavage for apoptosis in TRA-8 resistant TNBC cells. CaM antagonist, trifluoperazine, enhanced TRA-8 activated DR5 oligomerization, DR5-mediated DISC formation, and TRA-8 activated caspase cleavage for apoptosis, and decreased anti-apoptotic pERK, pAKT, XIAP, and cIAP-1 expression in TRA-8 resistant TNBC cells. These results suggest that CaM could be a key regulator to mediate DR5-mediated apoptotic signaling, and suggests a potential strategy for using CaM antagonists to overcome drug resistance of TRAIL-based therapy for TRA-8 resistant TNBC.

Abstract
The correlation of the most important prognostic indicators was evaluated in 75 breast cancer cases. Estrogen-progesterone receptors and proliferating activity were analyzed by immunocytochemical methods (ER-ICA, PR-ICA, Ki-67). Both steroid receptors were inversely correlated with the proliferating activity (ER-ICA vs Ki-67, p < 0.003; PR-ICA vs. Ki-67, p < 0.0001). No correlation was found between steroid receptors or cell kinetics and tumor size or lymph node status. These findings confirm the relevance of biochemical and kinetic parameters as independent markers in breast cancer and suggest a routine use of the simple immunocytochemical methods in assessing the biological behavior of tumors.

Int J Dermatol 2018; 57:410-416. [PMID: 29430630 DOI: 10.1111/ijd.13936] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/29/2017] [Revised: 11/16/2017] [Accepted: 01/09/2018] [Indexed: 12/01/2022]
Abstract
BACKGROUND Needle biopsy is a rapid, reliable, and reproducible procedure for histological confirmation of metastatic melanoma localization. Nonetheless, this procedure presents a theoretical risk of a mechanical weakening of the lymph node capsule with perinodal tumor seeding. The objective of the study was to evaluate the incidence of extracapsular extension after needle biopsy in comparison with surgical adenectomy in patients suspected of metastatic lymph node of melanoma. METHODS We conducted a retrospective study of 1056 patients who underwent lymphadenectomy for melanoma between 2000 and 2016 in our unit. Sixty-nine patients were clinically and/or radiologically suspected of metastatic lymph node of melanoma. Patients were divided according to external lymph node biopsy or surgical adenectomy before lymphadenectomy. The primary endpoint was the histopathological identification of extracapsular extension in analyzed lymph nodes. RESULTS The two populations were comparable except for the mitotic index, which was more frequently > 1/mm2 in the group with surgical adenectomy (P = 0.005). The proportion of extracapsular extension was significantly greater in the needle biopsy group (28/37) than in patients who underwent surgical adenectomy (14/32) (P = 0.0067; OR = 4 [95% CI: 1.4-11]). CONCLUSION Our results suggest an increased risk of extracapsular extension after external lymph node biopsy in cases of suspicion of metastatic lymph node of melanoma. Thus, this encourages us to prefer surgical adenectomy in patients with suspected adenopathy accessible surgically. In other cases, needle biopsy should be carried out under radiological guidance using devices limiting tumor seeding.

Abstract
Recent in situ hybridization experiments have shown a high content of IGF-II mRNA in breast cancer stroma. The aim of this study was to examine the relationship between IGF-II protein expression and several prognostic parameters in 75 infiltrating ductal carcinomas (IDC) of the breast. Tissue sections were evaluated for proliferative activity, IGF-II protein, ER, PgR, p53, and p21 expression using immunohistochemical procedures. The degree of stromal proliferation was assessed. Menopausal status, axillary lymph node involvement and nuclear grade were known. Thirty-five patients (44.3%) were premenopausal and 47 (62.6%) had lymph node metastases. Marked stromal proliferation was found in 34 (45.3%) specimens and high nuclear grade in 20 (26.5%). Eighteen tumors (24%) showed no IGF-II immunostaining. In the positive cases, IGF-II was detected both in the tumor stroma and in the cytoplasm of epithelial cancer cells: a high IGF-II content was found in 12 specimens (16.0%), a low content in 14 (18.7%) and a moderate content in 31 (41.3%). Twenty-four tumors (32.0%) showed high proliferative activity. Both ER and PgR were expressed in the nucleus of cancer cells: 49 tumors (65.3%) were ER positive (ER+) and 34 (45.3%) PgR positive (PgR+). p21 protein was detected in 37 tumors (49.6%) and p53 in 12 (16%). IGF-II protein was not correlated with menopausal status, lymph node metastases, nuclear grade, proliferative activity, ER or p53. In contrast, IGF-II correlated strongly with stromal proliferation (p=0.008), PgR (p=0.03) and p21 (p=0.01). This study demonstrates that in IDC of the breast IGF-II protein is expressed in the epithelium and stroma of the majority of tumors and is correlated with stromal amount, PgR and p21 expression. These preliminary results indicate that IGF-II expression in breast cancer is connected with two important regulators of breast cancer growth and differentiation.

Abstract
BACKGROUND Among all in-breast tumor recurrences (IBTR) following breast-conserving therapy (BCT), some comprise metachronous new primaries (NPs) while others are true recurrences (TRs). Establishing this distinction remains a challenge. METHODS We studied 3932 women who underwent BCT for stage I-III breast cancer from 1998 to 2008. Of these, 115 (2.9%) had an IBTR. Excluding patients with inoperable/unresectable recurrences or simultaneous distant metastases, 81 patients with isolated IBTR comprised the study population. An IBTR was categorized as an NP rather than a TR if it included an in situ component. The log-rank test and Kaplan-Meier method were used to evaluate disease-free survival (DFS) and overall survival (OS), and univariate and multivariate analyses were performed using Cox proportional hazards regression models. RESULTS At a median of 64.5 months from IBTR diagnosis, 28 of 81 patients had DFS events. Five-year DFS was 43.1% in the TR group (p = 0.0001) versus 80.3% in the NP group, while 5-year OS was 59.7% in the TR group versus 91.7% among those with NPs (p = 0.0011). On univariate analysis, increasing tumor size, high grade, positive margins, lymphovascular invasion, node involvement, lack of axillary surgery, chemotherapy, radiation therapy, and IBTR type (TR vs. NP) were significantly associated with worse DFS. Controlling for tumor size and margin status, TRs remained significantly associated with lower DFS (hazard ratio 3.717, 95% confidence interval 1.607-8.595, p = 0.002). CONCLUSION The presence of an in situ component is associated with prognosis among patients with IBTR following BCT and may be useful in differentiating TRs and NPs.

Abstract
Background Although breast cancer is relatively common, only about 5% of cases are due to inheritance of highly penetrant cancer susceptibility genes. The majority of these are caused by mutations in the BRCA1 and BRCA2 genes, which are also associated with an increased risk of ovarian cancer. Increased surveillance, chemoprevention, and prophylactic surgeries are standard options for the effective medical management of mutation carriers. However, optimal management of female carriers who choose to undergo prophylactic surgeries is still poorly understood. Methods The authors provide an overview of the current literature regarding medical management options for women carriers of BRCA1 and BRCA2 gene mutations and the implications for those individuals who have chosen to undergo prophylactic surgeries. Results BRCA mutation carriers who opt for prophylactic surgeries are still at risk for development of malignancy, and appropriate monitoring is warranted. Conclusions There are limited data on the appropriate medical management for BRCA mutation carriers after prophylactic surgeries. However, a management plan can be extrapolated from the general management recommendations for surveillance and other risk-reducing strategies in BRCA-positive individuals.

Abstract
Invasive lobular carcinoma (ILC) is the second most common kind of breast cancer. Diffusion weighted imaging (DWI) and positron emission tomography/computed tomography (PET/CT) are functional modalities for presenting the biological characteristics of breast cancer. The purpose of this article is to study the relationship between DWI or PET/CT and ILC's prognostic factors. The relationship between the apparent diffusion coefficient (ADC) values, standard uptake value (SUV)max and prognostic factors of ILC were statistically evaluated. The ADC values were lower in mass types of ILC. SUVmax was statistically higher in grade 3 and 4 background parenchymal enhancement and positive lymph node metastasis. ADC values of DWI and SUVmax of PET/CT can be helpful in the prediction of the prognosis of ILC.

Abstract
BACKGROUND Invasive lobular carcinoma (ILC) is known to be the second most common histological type following invasive ductal carcinoma (IDC). Definitive clinical features of ILC are controversial. METHODS We retrospectively analyzed a cohort of 330 patients with metastatic breast cancer, 303 of IDC, 19 of ILC, and 8 of others. We compared the patient age and tumor-node-metastasis factors, disease-free survival (DFS), estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor 2 (HER2) expression at the primary site between ILC and IDC. We then selected the patients in the ER+ or PR+/HER2- subtype specifically and compared sites of recurrence, and the survival curve starting from the point of development of metastatic disease. RESULTS The clinical stage was significantly higher in the ILC patients than in the IDC (p = 0.001). The mean (±SD) of DFS for the ILC and IDC patients was 2.6 ± 0.6 and 2.4 ± 0.3 years, respectively, with no significant difference (p = 0.18). However, the hormone receptor status was same between both groups; the rate of HER2 positivity was significantly lower in the ILC group (0%) than in the IDC group (16.2%) (p = 0.05). In ER+ or PR+/HER2- subtype, the mean DFS for the ILC and IDC was 2.9 ± 0.6 and 3.1 ± 0.3 years, and the median survival time after the recurrence for ILC and IDC patients was 4.2 ± 0.7 and 5.6 ± 0.7 years, respectively, with no significant difference (p = 0.77). The frequency of lung metastases was significantly lower in the ILC group (6.3%) than in the IDC group (53.7%) (p < 0.01), while the frequency of peritoneal metastases was significantly higher in the ILC group (68.8%) than in the IDC group (1%) (p = 0.00). Of note, the prognosis after the diagnosis of peritoneal metastases was poor, with a median survival time of 19 ± 9 months and resistance to hormone therapy. CONCLUSIONS The extremely high rate (68.8%) of peritoneal metastases was observed in long-term follow-up for the metastatic breast cancer patients with ILC. We need to reveal the definitive feature of ILC and develop new therapeutic strategies to prevent the dissemination of ILCs.

Abstract
Purpose Accelerated whole breast irradiation (AWBI) and conventional whole breast irradiation (CWBI) were compared to determine whether AWBI is as effective as CWBI in patients with early breast cancer and adverse prognostic features. Patients and methods We included 330 patients who underwent breast-conserving surgery (BCS) and post-operative radiation therapy (RT) using AWBI for pT1-2 and pN0-1a breast cancer from 2007 to 2010. These patients were matched with 330 patients who received CWBI according to stage, age (±3 years), and the year of BCS. AWBI of 39 Gy and CWBI of 50.4 Gy were given in 13 and 28 fractions, respectively. Results Median follow-up time was 81.9 months. There were no statistically significant differences between the AWBI and CWBI groups in terms of age, stage, tumor grade, or molecular subtype. More patients with Ki-67 index ≥ 14% were present in the AWBI group (AWBI 47.0% vs. CWBI 10.3%; P<0.01). The 5-year ipsilateral breast tumor relapse (IBTR) rates for the AWBI and CWBI groups were 0.8% and 1.8%, respectively (P=0.54). High tumor grade was a statistically significant risk factor for IBTR (5-year IBTR rate: 2.9%; P=0.01). Ki-67 ≥ 14% was marginally related to IBTR (5-year IBTR rate: 2.2%; P=0.07). There were no statistically significant differences in the hazard ratios between the AWBI and CWBI groups according to any of the risk factors. There were no acute grade 3 toxicities in the AWBI group. There were no late grade 3 toxicities in either group. Conclusions AWBI is comparable to CWBI in early breast cancer with adverse prognostic features.

Abstract
Lumpectomy with microscopically clear margins is a safe and effective approach for surgical management of breast carcinoma. Margins are positive for tumor in 18-50% of lumpectomies, as it is not possible to accurately determine the shape or microscopic borders of a tumor preoperatively or intraoperatively. We examined the 3D microanatomy and growth patterns of common breast carcinoma subtypes to provide guidance for lumpectomy surgery. Prospective consent was obtained for the use of excess tissue from patients undergoing lumpectomy or mastectomy for breast carcinoma. Tissue blocks from nine breast carcinomas were serially sectioned. Hematoxylin and eosin-stained slides at 100 μm intervals were scanned using a Nanozoomer (Hamamatsu, Japan) microscopic-resolution scanner. Three-dimensional reconstructions of tumors were created from scanned images using Reconstruct, open-access software. Breast carcinoma subtypes demonstrated characteristic growth patterns within breast tissue, which may have implications for lumpectomy surgery. Invasive ductal carcinomas showed a spherical shape, with a spiculated surface representing tumor cells infiltrating into surrounding parenchyma. Ductal carcinoma in situ appeared to spread along the duct system, creating dilated, tortuous, tumor-filled ducts. The invasive lobular carcinomas examined had a haphazard, linear, infiltrative growth pattern, different from the shape seen in ductal carcinomas. Our preliminary work suggests that invasive ductal and invasive lobular carcinomas appear to have distinct growth patterns in three dimensions and ductal carcinoma in situ appears to grow in a linear fashion along the duct network. The microanatomy studies described have the potential to guide refinements in breast lumpectomy technique.

Abstract
Eighty-five lesions of pure, noninvasive intraductal carcinoma were analyzed by histologic subtypes. The comedo subtype, defined by a solid growth pattern, high nuclear grade, and central necrosis, accounted for only seven lesions (8.2%). Solid, micropapillary, or cribriform patterns with central necrosis comprised 16 cases (18.8%), micropapillary 19 (22.4%), and cribriform 22 (25.9%). The comedo subtype showed several features different from the other subtypes. They occurred in younger patients and had higher numbers of duct profiles with carcinoma and larger tumor diameters. The intensities of lobular cancerization and periductal stromal chronic inflammation were also marked in the comedo lesions. Two of three comedo lesions examined by flow cytometry showed aneuploidy. Three of five tumors with nipple involvement contained at least some comedo-type duct profiles. These findings indicate greater potential aggressiveness of the comedo subtype. In contrast, the micropapillary and cribriform subtypes had fewer involved duct profiles, lower nuclear grade, and less mitotic activity. Microcalcification identified histologically, multifocality, and multicentricity were present in 54.1, 74.1, and 13.8%, respectively, of all lesions examined, and there were no differences between subtypes. Thus, the operative treatment of the comedo subtype (based on spread of disease within the breast) may not need to be more extensive than for other types of intraductal carcinoma. Central necrosis may prove to be of considerably less importance than nuclear grade in future evaluations of intraductal carcinoma.

Abstract
Peritumoral retraction artefact appears in tissue sections as an empty space partially or completely encircling a nest of tumor cells, usually in conformity with the rounded or angular outline of that particular nest. The present study was designed to test this finding in a large series of cases and to quantify the appearance of peritumoral retraction artefact in, in situ and infiltrating duct carcinoma of the breast. We examined 199 cases of infiltrating duct carcinoma (IDC) and 188 cases of ductal carcinoma in situ (DCIS). Of the total of 387 cases, 111 were core needle biopsies, whereas the others were larger resections. In each specimen, retraction was evaluated on hematoxylin and eosin-stained slides as negative, 1+ (1% to 25% of tumor showing retraction), 2+ (26% to 50%), 3+ (51% to 75%), or 4+ (76% to 100%). Overall, peritumoral retraction was noted in 168 of 199 cases (84.4%) of IDC, versus 30 of 188 cases (16%) of DCIS ( P < 0.0001). Peritumoral retraction scored as 2+ or greater (26% to 50%) was seen in only 1 of 188 DCIS specimens, compared with 77 of 199 IDC. Thus, peritumoral retraction artefact appears to be a significant finding seen during the evaluation of hematoxylin and eosin specimens for the diagnosis of carcinoma. We discuss the possibility that this phenomenon might represent true prelymphatic space involvement rather than a fixation artefact.

Abstract
BACKGROUNDS AND OBJECTIVES Medullary breast carcinoma (MBC) is a subtype with a more favorable prognosis. Tumors with some, but not all, characteristics of MBC are classified as atypical medullary carcinoma of the breast (AMCB). METHODS Patients with invasive MBC and AMCB reported to the National Cancer Data Base (NCDB) from 2004 to 2013 were compared for tumor characteristics and overall survival, using infiltrating ductal carcinoma (IDC) as a reference. RESULTS Patients with MBC (n = 3,688), AMCB (n = 288), and IDC (n = 918,870) met inclusion criteria. Comparing MBC with AMCB, the mean age at diagnosis (52.9 vs. 53.9 years), mean tumor size (2.4 vs. 2.5 cm), lymph node positivity (22.8% vs. 22.4%), estrogen receptor (ER) positivity (22% vs. 25%), progesterone receptor (PR) positivity (14% vs. 15%), HER2 positivity (11% vs. 14%), rate of breast conserving surgery (67% vs. 68%), use of chemotherapy (76% vs. 75%), and use of hormonal therapy (19% vs. 18%), respectively, were not clinically or statistically different. Five-year (92% vs. 89%) and 10-year survival rates (85% vs. 87%) were not significantly different (P = 0.46). CONCLUSIONS There does not appear to be any reason to differentiate between AMCB and MBC given the similarities in presentation, treatment and prognosis. J. Surg.

Nipple adenoma in a female patient presenting with persistent erythema of the right nipple skin: case report, review of the literature, clinical implications, and relevancy to health care providers who evaluate and treat patients with dermatologic conditions of the breast skin. BMC DERMATOLOGY 2016; 16:4. [PMID: 27206635 PMCID: PMC4873987 DOI: 10.1186/s12895-016-0041-6] [Citation(s) in RCA: 29] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/04/2016] [Accepted: 05/09/2016] [Indexed: 12/27/2022]
Abstract
Background Nipple adenoma is a very uncommon, benign proliferative process of lactiferous ducts of the nipple. Clinically, it often presents as a palpable nipple nodule, a visible nipple skin erosive lesion, and/or with discharge from the surface of the nipple skin, and is primarily seen in middle-aged women. Resultantly, nipple adenoma can clinically mimic the presentation of mammary Paget’s disease of the nipple. The purpose of our current case report is to present a comprehensive review of the available data on nipple adenoma, as well as provide useful information to health care providers (including dermatologists, breast health specialists, and other health care providers) who evaluate patients with dermatologic conditions of the breast skin for appropriately clinically recognizing, diagnosing, and treating patients with nipple adenoma. Case presentation Fifty-three year old Caucasian female presented with a one year history of erythema and induration of the skin of the inferior aspect of the right nipple/areolar region. Skin punch biopsies showed subareolar duct papillomatosis. The patient elected to undergo complete surgical excision with right central breast resection. Final histopathologic evaluation confirmed nipple adenoma. The patient is doing well 31 months after her definitive surgical therapy. Conclusions Since nipple adenoma represents a benign proliferative process of the nipple, complete surgical excision is curative. However, the coexistence of nipple adenoma and ipsilateral or contralateral breast cancer is well reported in the literature. The potential for a direct causal link or association of nipple adenoma and breast cancer cannot be fully excluded.

Intratumoral estrogen production and actions in luminal A type invasive lobular and ductal carcinomas. Breast Cancer Res Treat 2016; 156:45-55.

Abstract
The great majority of invasive lobular carcinoma (ILC) is estrogen-dependent luminal A type carcinoma but the details of estrogen actions and its intratumoral metabolism have not been well studied compared to invasive ductal carcinoma (IDC). We first immunolocalized estrogen-related enzymes including estrogen sulfotransferase (EST), estrogen sulfatase (STS), 17β-hydroxysteroid dehydrogenase (HSD) 1/2, and aromatase. We then evaluated the tissue concentrations of estrogens in ILC and IDC and subsequently estrogen-responsive gene profiles in these tumors in order to explore the possible differences and/or similarity of intratumoral estrogen environment of these two breast cancer subtypes. The status of STS and 17βHSD1 was significantly lower in ILCs than IDCs (p = 0.022 and p < 0.0001), but that of EST and 17βHSD2 vice versa (p < 0.0001 and p = 0.0106). In ILCs, tissue concentrations of estrone and estradiol were lower than those in IDCs (p = 0.0709 and 0.069). In addition, the great majority of estrogen response genes tended to be lower in ILCs. Among those genes above, FOXP1 was significantly higher in ILCs than in IDCs (p = 0.002). FOXP1 expression was reported to be significantly higher in relapse-free IDC patients treated with tamoxifen. Therefore, tamoxifen may be considered an option of endocrine therapy for luminal A type ILC patients. This is the first study to demonstrate the detailed and comprehensive status of intratumoral production and metabolism of estrogens and the status of estrogen response genes in luminal A-like ILC with comparison to those in luminal A-like IDCs.

Abstract
Invasive ductal and lobular carcinomas (IDC and ILC) are the two most common histological types of breast cancer, and have been considered to develop from terminal duct lobular unit but their molecular, pathological, and clinical features are markedly different between them. These differences could be due to different mechanisms of carcinogenesis and tumor microenvironment, especially cancer-associated fibroblasts (CAFs) but little has been explored in this aspect. Therefore, in this study, we evaluated the status of angiogenesis, maturation of intratumoral microvessels, and proliferation of CAFs using immunohistochemistry and PCR array analysis to explore the differences of tumor microenvironment between ILC and IDC. We studied grade- and age-matched, luminal-like ILC and IDC. We immunolocalized CD34 and αSMA for an evaluation of CAFs and CD31, Vasohibin-1, a specific marker of proliferative endothelial cells and nestin, a marker of pericytes for studying the status of proliferation and maturation of intratumoral microvessel. We also performed PCR array analysis to evaluate angiogenic factors in tumor stromal components. The number of CAFs, microvessel density, and vasohibin-1/CD31 positive ratio were all significantly higher in ILC than IDC but nestin immunoreactivity in intratumoral microvessel was significantly lower in ILC. These results did indicate that proliferation of CAFs and endothelial cells was more pronounced in ILC than IDC but newly formed microvessels were less mature than those in IDC. PCR array analysis also revealed that IGF-1 expression was higher in ILC than IDC. This is the first study to demonstrate the differences of tumor microenvironment including CAFs and proliferation and maturation of intratumoral vessels between ILC and IDC.

Abstract
BACKGROUND Over-treatment of estrogen receptor positive (ER+), lymph node-negative (LNN) breast cancer patients with chemotherapy is a pressing clinical problem that can be addressed by improving techniques to predict tumor metastatic potential. Here we demonstrate that analysis of second harmonic generation (SHG) emission direction in primary tumor biopsies can provide prognostic information about the metastatic outcome of ER+, LNN breast cancer, as well as stage 1 colorectal adenocarcinoma. METHODS SHG is an optical signal produced by fibrillar collagen. The ratio of the forward-to-backward emitted SHG signals (F/B) is sensitive to changes in structure of individual collagen fibers. F/B from excised primary tumor tissue was measured in a retrospective study of LNN breast cancer patients who had received no adjuvant systemic therapy and related to metastasis-free survival (MFS) and overall survival (OS) rates. In addition, F/B was studied for its association with the length of progression-free survival (PFS) in a subgroup of ER+ patients who received tamoxifen as first-line treatment for recurrent disease, and for its relation with OS in stage I colorectal and stage 1 lung adenocarcinoma patients. RESULTS In 125 ER+, but not in 96 ER-negative (ER-), LNN breast cancer patients an increased F/B was significantly associated with a favorable MFS and OS (log rank trend for MFS: p = 0.004 and for OS: p = 0.03). On the other hand, an increased F/B was associated with shorter PFS in 60 ER+ recurrent breast cancer patients treated with tamoxifen (log rank trend p = 0.02). In stage I colorectal adenocarcinoma, an increased F/B was significantly related to poor OS (log rank trend p = 0.03), however this relationship was not statistically significant in stage I lung adenocarcinoma. CONCLUSION Within ER+, LNN breast cancer specimens the F/B can stratify patients based upon their potential for tumor aggressiveness. This offers a "matrix-focused" method to predict metastatic outcome that is complementary to genomic "cell-focused" methods. In combination, this and other methods may contribute to improved metastatic prediction, and hence may help to reduce patient over-treatment.

Abstract
Introduction Solitary uterine metastases from extragenital cancers are very rare. Breast cancer is the most frequent primary site of metastasis to the uterine corpus, with invasive lobular carcinoma more likely to spread to gynecologic organs than invasive ductal carcinoma. Case presentation A 62-year-old postmenopausal Japanese woman was diagnosed with uterine leiomyomata more than 20 years ago and had been managed conservatively until menopause. Seven years prior to her presentation, she was diagnosed with breast cancer and underwent a partial resection of her right breast for stage IIA invasive lobular carcinoma. She underwent adjuvant chemotherapy, radiotherapy, and five years of anastrozole hormonal therapy. She presented with a growing uterine mass. Her tumor marker levels were markedly increased over the course of her follow-up, but a systemic examination revealed only a solitary uterine tumor. She underwent a total abdominal hysterectomy with bilateral salpingo-oophorectomy. A histopathological examination, including detailed immunohistochemistry, confirmed metastatic invasive lobular carcinoma, infiltrating both her uterine myometrium and fibroid tissue. Conclusion We report a very rare metastatic pattern of invasive lobular carcinoma and demonstrate that gross cystic disease fluid protein-15 and mammaglobin are useful in the diagnosis of metastatic breast cancer.

Abstract
With enhanced public awareness, advances in breast imaging, and emphasis on early breast cancer detection and prevention, more women are seeking consultation to assess the status of their breast health. Risk assessment has become an integral part of established multi-disciplinary breast care, and breast cancer risk reduction interventions have received a great deal of attention. Similarly, interest in identification of high-risk individuals has increased significantly. Atypical proliferative changes in breast epithelial cells are ranked high among various known breast cancer risk factors and, in recent years, have been the subject of several investigations. Breast tissue and fluid in the ductal system provide a rich source of cells and biomarkers that have the potential to aid in the assessment of short-term risk of breast cancer development, and assess responses to interventional prevention efforts. There are three minimally invasive procedures currently being utilized to sample breast tissue in asymptomatic high-risk individuals. These procedures are: fine-needle aspiration biopsy, nipple aspiration fluid, and ductal lavage. In this review article, the merits and limitations of each procedure are presented, and the contribution of cytomorphology and molecular analysis in breast cancer prediction is highlighted. In addition, the role of Masood Cytology Index as a surrogate endpoint biomarker in chemopreventative trials is discussed.

Abstract
Introduction Epigenetic modifications such as aberrant DNA methylation has long been associated with tumorogenesis. Little is known, however, about how these modifications appear in cancer progression. Comparing the methylome of breast carcinomas and locoregional evolutions could shed light on this process. Methods The methylome profiles of 48 primary breast carcinomas (PT) and their matched axillary metastases (PT/AM pairs, 20 cases), local recurrences (PT/LR pairs, 17 cases) or contralateral breast carcinomas (PT/CL pairs, 11 cases) were analyzed. Univariate and multivariate analyzes were performed to determine differentially methylated probes (DMPs), and a similarity score was defined to compare methylation profiles. Correlation with copy-number based score was calculated and metastatic-free survival was compared between methods. Results 49 DMPs were found for the PT/AM set, but none for the others (FDR ). Hierarchical clustering clustered 75% of the PT/AM, 47% of the PT/LR, and none of the PT/CL pairs together. A methylation-based score (MS) was defined as a clonality measure. The PT/AM set contained a high proportion of clonal pairs while PT/LR pairs were evenly split between high and low MS score, suggesting two groups: true recurrences (TR) and new primary tumors (NP). CL were classified as new tumors. MS score was significantly correlated with copy-number based scores. There was no significant difference between the metastatic-free survival of groups of patients based on different classifications. Conclusion Epigenomic alterations are well suited to study clonality and track cancer progression. Methylation-based classification of TR and NP performed as well as clinical and copy-number based methods suggesting that these phenomenons are tightly linked.

Abstract
Background Loss of cadherin 1 (CDH1) expression, which is normally involved in cell adhesion and maintenance of tissue architecture, is a hallmark of invasive lobular carcinoma (ILCA). Because hereditary cancers may require different risk reduction, counseling and treatment options than sporadic cancer, it is critical to determine the prevalence of germline CDH1 mutations in patients with ILCA. Methods All patients with ILCA (n = 100) previously enrolled in the Clinical Breast Care Project were identified. Genomic DNA was isolated from peripheral blood samples and DNA variants were detected for each exon of CDH1 using high-resolution melting technology followed by direct sequencing. Results Within the 100 samples screened, four nonsynonymous variants were detected: A592T in one Hispanic patient, A617T in two patients, both African American, P825L in a Causasian patient whose grandmother had stomach cancer, and G879S in a Caucasian patient. Further evaluation of A617T in an additional 165 African American patients found that 11 patients, none with ILCA, carried this variant including one patient who was homozygous for the variant. Conclusions CDH1 mutations are infrequent in patients with ILCA, and the variants that were detected have been classified as non-pathogenic. These data suggest that ILCA does not have a significant hereditary component and do not support CDH1 gene mutation testing in patients with ILCA.

Abstract
Background. Fine-needle aspiration cytology plays a major role in the primary diagnosis of breast carcinoma. Cytological grading of the smears can provide valuable prognostic information and aid in planning the management options. Aim. To evaluate various 3-tier cytological grading systems and to determine the best possible system which is reliable and objective for use in routine practice. Materials & Methods. 72 fine-needle aspiration smears of breast carcinomas were graded by two pathologists and compared with the histologic grading by Nottingham modification of Scarff-Bloom-Richardson method. Concordance and correlation studies were done. Kappa measurement of interobserver agreement was also done. Results. Robinson's method showed a better correlation (77.7%) and substantial Kappa value of agreement (κ = 0.61) with Bloom Richardson's histological grading method in comparison to the other methods, closely followed by Fisher's method. Fisher's method showed better interobserver agreement (84.7%, κ = 0.616) compared to the other systems. Conclusions. Robinson's method of cytological grading in fine-needle aspiration smears of breast carcinoma is simpler, multifactorial, and feasible, hence being preferable for routine use according to our study.

Abstract
BACKGROUND The role of nipple-sparing mastectomy (NSM) for breast cancer is controversial as there is concern regarding its oncological safety and complication rate. We carried out a review of the literature to quantify the incidence of occult nipple malignancy in breast cancer, identify the factors influencing occult nipple malignancy, quantify locoregional recurrence rates and quantify NSM complication rates. METHODS A search of the literature was performed using PubMed. Keywords used were "mastectomy", "nipple involvement", "nipple-sparing mastectomy", "skin-sparing mastectomy" "occult nipple malignancy" "occult nipple disease" "breast cancer recurrence". Articles were analyzed regarding incidence of occult nipple malignancy, potential factors influencing the incidence of occult malignancy and recurrence/complications following NSM. The incidence of occult nipple disease was compared between groups using Chi(2) or Fisher's exact tests for categorical variables and Student's t-tests for continuous variables. P values were considered significant<0.05. We identified nearly 30 studies compiling nearly 10 000 cases examining the rate of occult nipple malignancy and 23 studies compiling 2300 cases providing information on the rate of local recurrence after NSM. RESULTS The overall rate of occult nipple malignancy was 11.5 %. Primary tumour characteristics influencing occult nipple malignancy were tumour-nipple distance<2cm, grade, lymph node metastasis, lymphovascular invasion, HER2 positive, ER/PR negative, tumour size>5cm, retro-areolar/central location and multicentric tumours. The overall nipple recurrence rate following NSM was 0.9 %, skin flap recurrence rate was 4.2 %. Full and partial thickness nipple necrosis rates were 2.9 % and 6.3 % respectively. CONCLUSION NSM for primary breast cancer is appropriate in carefully selected patients. All patients should have retro-areolar sampling. There is strong evidence to suggest that suitable cases are well circumscribed single or multifocal lesions that have a TND>2cm. Tumours should be graded 1-2 and not have LVI, axillary node metastasis or HER2 positivity.

Abstract
We have previously indicated that the ideal animal tumor model should mimic the human disease. This means that the investigator should be able to ascertain the influence of host factors on the initiation of tumorigenesis, mimic the susceptibility of tumor response based on age and reproductive history, and determine the response of the tumors induced to chemotherapy. The utilization of experimental models of mammary carcinogenesis in risk assessment requires that the influence of ovarian, pituitary, and placental hormones, among others, as well as overall reproductive events are taken into consideration, since they are important modifiers of the susceptibility of the organ to neoplastic development. Several species, such as rodents, dogs, cats, and monkeys, have been evaluated for these purposes; however, none of them fulfills all the criteria specified previously. Rodents, however, are the most widely used models; therefore, this work will concentrate on discussing the rat rodent model of mammary carcinogenesis.

Abstract
PURPOSE To assess the prevalence of phosphoinositide 3-kinase (PI3K) pathway alterations in pure high-grade ductal carcinoma in situ (DCIS) and DCIS associated with invasive breast cancer (IBC), and to determine whether DCIS and adjacent IBCs harbor distinct PI3K pathway aberrations. EXPERIMENTAL DESIGN Eighty-nine cases of pure high-grade DCIS and 119 cases of high-grade DCIS associated with IBC were characterized according to estrogen receptor (ER) and HER2 status, subjected to immunohistochemical analysis of PTEN, INPP4B, phosphorylated (p)AKT and pS6 expression, and to microdissection followed by Sequenom genotyping of PIK3CA and AKT1 hotspot mutations. RESULTS Alterations affecting the PI3K pathway were found in a subset of pure DCIS and DCIS adjacent to IBC. A subtype-matched comparison of pure DCIS and DCIS adjacent to IBC revealed that PIK3CA hotspot mutations and pAKT expression were significantly more prevalent in ER-positive/HER2-negative DCIS adjacent to IBC (P values, 0.005 and 0.043, respectively), and that in ER-negative/HER2-positive cases INPP4B loss of expression was more frequently observed in pure DCIS (a P value of 0.013). No differences in the parameters analyzed were observed in a pairwise comparison of the in situ and invasive components of cases of DCIS and adjacent IBC. Analysis of the PIK3CA-mutant allelic frequencies in DCIS and synchronous IBC revealed cases in which PIK3CA mutations were either restricted to the DCIS or to the invasive components. CONCLUSION Molecular aberrations affecting the PI3K pathway may play a role in the progression from high-grade DCIS to IBC in a subset of cases (e.g., a subgroup of ER-positive/HER2-negative lesions).

Abstract
Invasive lobular carcinoma (ILC) is a histologic subtype of breast cancer that is frequently associated with favorable outcomes, as approximately 90% of ILC express the estrogen receptor (ER). However, recent retrospective analyses suggest that patients with ILC receiving adjuvant endocrine therapy may not benefit as much as patients with invasive ductal carcinoma. On the basis of these observations, we characterized ER function and endocrine response in ILC models. The ER-positive ILC cell lines MDA MB 134VI (MM134) and SUM44PE were used to examine the ER-regulated transcriptome via gene expression microarray analyses and ER ChIP-Seq, and to examine response to endocrine therapy. In parallel, estrogen response was assessed in vivo in the patient-derived ILC xenograft HCI-013. We identified 915 genes that were uniquely E2 regulated in ILC cell lines versus other breast cancer cell lines, and a subset of these genes were also E2 regulated in vivo in HCI-013. MM134 cells were de novo tamoxifen resistant and were induced to grow by 4-hydroxytamoxifen, as well as other antiestrogens, as partial agonists. Growth was accompanied by agonist activity of tamoxifen on ER-mediated gene expression. Though tamoxifen induced cell growth, MM134 cells required fibroblast growth factor receptor (FGFR)-1 signaling to maintain viability and were sensitive to combined endocrine therapy and FGFR1 inhibition. Our observation that ER drives a unique program of gene expression in ILC cells correlates with the ability of tamoxifen to induce growth in these cells. Targeting growth factors using FGFR1 inhibitors may block survival pathways required by ILC and reverse tamoxifen resistance.
