The clinical decision to excise intraductal papilloma (IDP) without atypia diagnosed on biopsy remains controversial. We sought to establish clinical and histologic predictors (if any) which may predict upgrade in IDP. 296 biopsies (in 278 women) with histologic diagnosis of IDP without atypia were retrospectively identified and placed into Incidental (no corresponding imaging correlate), or Non-incidental (positive imaging correlate) groups. 253/296 (85.5%) cases were non-incidental, and 43/296 (14.5%) were incidental...

Patients with atypical hyperplasia and lobular carcinoma in situ (LCIS) (atypical breast lesions) are at high risk of developing breast cancer, and chemoprevention has been shown to confer a substantial reduction in that risk. Despite this, the overall rate of chemoprevention utilization in this group is low. This study evaluates the efficacy of a formal individualized education and counseling session on patient acceptance and adherence to chemoprevention. Patients with atypical breast lesions having an individualized education and counseling session in a single surgical oncology practice were prospectively entered into a database from 2001 to 2016, and with IRB approval, their data were analyzed...

Mutational inactivation of E-cadherin (CDH1) is the main driver of invasive lobular breast cancer (ILC), although approximately 10-15% of all ILCs retain membrane-localized E-cadherin, despite the presence of an apparent non-cohesive and invasive lobular growth pattern. Given that ILC is dependent on constitutive actomyosin contraction for tumor development and progression, we used a combination of cell systems and in vivo experiments to investigate the consequences of α-catenin (CTNNA1) loss in the regulation of anchorage independence of non-invasive breast carcinoma...

Objective: Invasive lobular carcinoma (ILC) of the breast makes up 5 to 15 percent of all invasive breast cancers. It has distinctive clinical and histopathological features when compared to invasive ductal carcinoma (IDC). This study intends to describe factors influencing sentinel lymph node (SLN) positivity in patients with "pure" ILC. Materials and Methods: Data of 105 patients, who were treated at a tertiary oncology center, with lobular carcinoma of the breast that were subjected to SLN biopsy was probed retrospectively...

An incomplete regression of the mammary line during embryogenesis occurs in 0.2-6% of the population, which may result in the presence of ectopic breast tissue (EBT). The development of a carcinoma in the EBT is a rare event. The authors present a case report of a 76-year-old female patient, with a lobular carcinoma in an abdominal wall EBT submitted to surgery and adjuvant chemotherapy.

BACKGROUND: Infiltrating lobular carcinoma (ILC) represents about 10% of breast cancer and rarely shows overexpression of human epidermal growth factor receptor 2 (HER2). We compared biological and clinical characteristics of HER2-positive ILC versus HER2-positive infiltrating ductal carcinoma (IDC). PATIENTS AND METHODS: We retrospectively analyzed the data of 328 patients with HER2-positive pure ductal or lobular breast carcinoma, comparing clinical and biological data at diagnosis as well as outcome between the 2 histologies...

Morphological variants of lobular carcinoma in situ (LCIS) include classical- (CLCIS), pleomorphic- (PLCIS) and florid-type (FLCIS). Treatment guidelines suggest managing PLCIS and FLCIS like ductal carcinoma in situ (DCIS); therefore accurate identification of LCIS subtypes is critical. However significance of separating PLCIS from FLCIS is not clear. Also inter-observer agreement in identifying LCIS subtypes, using contemporary criteria, is not known. We aimed to evaluate inter-observer agreement amongst breast pathologists in diagnosing LCIS subtypes and use the agreement data to justify LCIS classification for management purposes...

The occurrence of bilateral breast cancer is rare. A second primary in the contralateral breast can either be synchronous or metachronous. Lobular carcinoma of the breast is known for its multicentricity and bilateral spread. The synchronous mixed pattern of carcinoma of the breast has also been reported in the same breast. The family history of breast carcinoma, estrogen receptor negativity, and human epidermal growth factor receptor-2 positivity are risk factors for the development of contralateral breast malignancy...

Invasive lobular carcinoma (ILC) is the second most common histological subtype of breast cancer following invasive ductal carcinoma (IDC). ILC differs from IDC in a number of histological and clinical features, such as single strand growth, difficulty in detection, and frequent late recurrences. To understand the molecular pathways involved in the clinical characteristics of ILC, we compared the gene expression profiles of luminal A ILC and luminal A IDC using data from TCGA and utilized samples from METABRIC as a validation data set...

BACKGROUND There are few reports of breast cancer cases with uterine metastases; among them, myometrium is more frequently involved than endometrium. The majority of breast cancer metastases to endometrium are lobular type, and there have been only 5 reported cases of ductal type since 1984. Here, we describe a new case of invasive ductal carcinoma with metastases to endometrium and isolated presentation of abnormal uterine bleeding, in addition to reviewing the existing literature on other similar cases. CASE REPORT The patient was a 51-year-old Persian woman with no remarkable past medical or family history of cancer, who presented with a 6-month complaint of menorrhagia to our gynecology clinic...

Due to the potential for atypia (atypical ductal or lobular hyperplasia) or carcinoma (in situ or invasive) on excision, aggressive reflex surgical excision protocols following core biopsy diagnosis of papillary lesions of the breast (ie, intraductal papilloma) are commonplace. Concepts in risk stratification, including radiologic-pathologic correlation, are emerging in an effort to curb unnecessary surgeries. To this end, we examined all excised intraductal papillomas diagnosed at our institution from 2010-2015 (N = 336) and found an overall atypia rate of 20%...

BACKGROUND: Immune checkpoint regulators, cytotoxic T lymphocyte antigen 4 (CTLA-4) and the programmed cell death protein-1/programmed death-ligand 1 (PD-1/PD-L1) have emerged as promising new targets for cancer therapeutics. While tumor expression of PD-L1 has been shown to have objective responses to anti-PD-L1 immunotherapies, the clinical implications of CTLA-4 expression in tumor cells or immune cells in the tumor microenvironment is still controversial. We investigated the expression of CTLA-4 and PD-L1 in human breast tumors and provided a scoring system for the systematic evaluation of CTLA-4 staining...

Pleomorphic invasive lobular carcinoma (PILC) is an aggressive variant of invasive lobular breast cancer that is associated with poor clinical outcomes. Limited molecular data are available to explain the mechanistic basis for PILC behavior. To address this issue, targeted sequencing was performed to identify molecular alterations that define PILC. This sequencing analysis identified genes that distinguish PILC from classic ILC and invasive ductal carcinoma by the incidence of their genomic changes. In particular, insulin receptor substrate 2 (IRS2) is recurrently mutated in PILC, and pathway analysis reveals a role for the insulin receptor (IR)/insulin-like growth factor-1 receptor (IGF1R)/IRS2 signaling pathway in PILC...

BACKGROUND: Intraoperative evaluation of the axillary sentinel lymph node (SLN) in patients with breast carcinoma reduces the need of re-operations in cases where an axillary completion lymph node dissection (CLND) is indicated. Different methods have been used to determine the SLN status intraoperatively, e.g. frozen section histology (FS) and touch imprint cytology (TIC). The sensitivity of intraoperative TIC examination on SLN is not consistent between different studies and varies according to different tumor histologic subtypes, tumor size and the age of the patient...

Breast metastases are a relatively rare condition and account for approximately 0.5-2% of all breast tumors. Recognition of metastatic tumors in the breast is important because it would prevent unnecessary mutilating surgery and would lead to appropriate treatment of the primary tumor. Breast metastases from medullary thyroid cancer (MTC) are very rare with only 21 reported cases in the literature. Some MTCs mimic primary invasive lobular carcinoma of the breast histopathologically and radiologically, making the distinction between the two diagnostically challenging...
