Invasive lobular carcinoma of the breast is known to produce intracellular mucin and has been recognized in single-case reports to show extracellular mucin production, as well. This latter morphology is not only rare but must also be under- or misdiagnosed. The aim was to better characterize this entity. Cases of lobular cancers demonstrating extracellular mucin formation were identified in a multi-institutional effort and their clinical and morphologic features were assessed. Immunohistochemistry was used to characterize the E-cadherin-membrane complex, neuroendocrine differentiation, and to some extent, mucin formation...

PURPOSE: Identification of clinicopathological factors predicting for a locoregional recurrence (LRR) after neoadjuvant chemotherapy (NAC) could help to decide on the optimal locoregional radiotherapy. The objective of this trial is to identify those factors in the context of a phase III trial (European Organisation for Research and Treatment of Cancer 10994). METHODS: Patients received NAC followed by surgery with or without radiotherapy. Radiotherapy was administered according to pre-specified guidelines...

BACKGROUND: The role of surveillance breast MRI for women with mammographically dense breasts, a personal history of breast cancer (BC), atypical hyperplasia (AH), or lobular carcinoma in situ (LCIS) is unclear. We estimated the performance of annual surveillance MRI in women with a combination of these risk factors. METHODS: We performed a retrospective review of the clinical, radiological, and pathological parameters of women who received annual concurrent surveillance breast MRI and mammography between 04/2013 and 12/2015 and fulfilled all of the following criteria: 1) age <70; 2) prior diagnosis of AH, LCIS or BC; 3) heterogeneously or extremely dense breast(s); and 4) did not qualify for our provincial breast MRI high risk screening program...

Breast cancer (BC) in Oman affects younger women and has a more aggressive course. Clinical and biological variables like age, pregnancy, tumor size, type, grade, receptor expression and proliferation predict disease aggression but there is no direct predictor of metastasis except lymphovascular invasion. Epithelial-mesenchymal transition (EMT) is characterized by epithelial cells losing epithelial and acquiring mesenchymal morpho-immunophenotypic characteristics. In tumors, EMT-like transitions may signify a metastatic phenotype and have features in common with cancer stem cells (CSC) which show resistance to chemotherapy...

INTRODUCTION: We studied the effect of neoadjuvant chemotherapy (NAC) ± trastuzumab on the ductal carcinoma in situ (DCIS) component in patients with locally advanced breast cancer who achieved pathological complete response (pCR). METHODS: The diagnostic biopsies of 92 consecutive breast cancer patients that were treated with neoadjuvant chemotherapy (NAC) ± trastuzumab were evaluated for the presence of DCIS. Upon completion of NAC, the surgical specimens were evaluated for complete eradication of both the invasive and non-invasive cancer in the breast...

BACKGROUND: A relationship between baseline tumor-infiltrating lymphocytes (TIL) and outcomes has been described in HER2-positive breast cancer. Nevertheless, the magnitude of this association and whether this effect differs based on the type of anti-HER2 agent remain controversial. This meta-analysis investigated the association between baseline TIL and pathologic complete response (pCR) rates in HER2-positive breast cancer patients treated with neoadjuvant chemotherapy plus trastuzumab and lapatinib either alone or in combination...

The Hippo pathway regulates cell proliferation and apoptosis and it has been noted that loss of critical components of this pathway can lead to uncontrolled cell growth. Yes-associated protein (YAP) is an important component of this Hippo pathway because YAP is the nuclear effector of the Hippo tumor suppressor pathway and it is crucial for the response to oxidative stress induced by cellular process and by different xenobiotics, including arsenic. It has been proposed that YAP dysregulation can contribute to a malignant cellular phenotype acting as both a tumor suppressor and an oncogene...

Triple-negative breast cancer (TNBC) indicates a subset of breast carcinomas that does not express estrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor-2 (HER2). According to the literature, TNBCs are aggressive tumors, characterized by a high incidence of recurrence and a high risk of disease progression. Lactoferrin (LF) is a single-chain, iron-binding glycoprotein of ~700 amino acids, which is involved in a wide range of biological activities, including iron-trafficking and carcinogenesis...

PURPOSE: The new ASCO/CAP guidelines published in 2013 (AC2013) significantly modified the scoring criteria for HER2-FISH, introducing the most controversial change to the HER2-equivocal category. We retrospectively evaluated the impact of AC2013 in a cohort of consecutive invasive breast cancers (IBCs) analyzed with frontline dual-color FISH. METHODS: 2788 consecutive IBCs were reclassified based on the AC2013 guidelines. Clinico-pathological features of equivocal IBCs were compared with HER2-negative and HER2-positive IBCs...

Lisa A Newman
Treatment of early-stage invasive breast cancer with breast-conserving surgery plus radiation therapy (RT) yields overall survival outcomes equivalent to those achieved with mastectomy. Further, breast-conserving surgery is endorsed by the National Comprehensive Cancer Network as being supported by the highest-level, category 1 evidence. Advances in pathologic evaluation, management of multiple tumors, oncoplastic lumpectomy techniques, neoadjuvant chemotherapy, and hypofractionated RT can expand the pool of patients eligible for breast-conserving surgery...

Acellular dermal matrix (ADM) such as Alloderm(®) is sometimes used in tissue reconstruction in primary and reconstructive breast surgeries. As ADM is incorporated into the native tissues, the evolving imaging findings that would correlate with varying degrees of host migration and neoangiogenesis into the matrix can be challenging to recognize. In the setting of a palpable or clinical area of concern after breast reconstructive surgery following breast cancer, confident diagnosis of a mass representing ADM rather than recurring or developing disease can be challenging...

BACKGROUND: Cosmetic result following breast conserving surgery (BCS) for cancer influences quality of life and psychosocial functioning in breast cancer patients. A preoperative prediction of expected cosmetic result following BCS is not (yet) standard clinical practice and therefore the choice for either mastectomy or BCS is still subjective. Recently, we showed that tumour volume to breast volume ratio as well as tumour location in the breast are independent predictors of superior cosmetic result following BCS...
