Primary neuroendocrine carcinoma of the breast (NECB) is a rare malignant tumor with controversial biological behavior and a lack of data guiding treatment decisions due to its scarcity. Cancer gene-expression profiling tests provide a better indication of clinical prognosis and help determine the best clinical management versus the traditional clinical and pathological parameters. This is a report of a NECB with a genetic assay that showed a low-risk tumor despite high-grade and poorly differentiated histopathological features...

Pleomorphic adenoma is a common tumor encountered in major salivary gland and very rarely seen in breast. This matrix producing tumor can be confused with fibroadenoma, phyllodes tumor and metaplastic carcinoma on fine needle aspiration cytology(FNAC). Pre-operative diagnosis of pleomorphic adenoma helps in preventing surgical over or under treatment of the disease. We present an extremely rare case of pleomorphic adenoma of breast diagnosed on FNAC with histopathological confirmation.

OBJECTIVE: To review the literature on chest wall resection for recurrent breast cancer and evaluate overall survival (OS) and quality-of-life (QOL) outcomes. BACKGROUND: Full-thickness chest wall resection for recurrent breast cancer is controversial, as historically these recurrences have been thought as a harbinger of systemic disease. METHODS: A systematic search in MEDLINE, EMBASE, and Cochrane CENTRAL identified 48 eligible studies, all retrospective, accounting for 1305 patients...

Residual carcinoma confined to lymphovascular spaces following neoadjuvant chemotherapy (NAC) for invasive breast carcinoma is an uncommon finding. We studied pathologic features and outcome for patients with pure intralymphatic carcinoma (PIC) following NAC, a pattern of residual disease reported to have a poor outcome in the only previously published series of this entity. Six of 284 (2.1%) patients treated with NAC were studied. All 6 patients had axillary lymph node involvement before NAC. Tumors were triple-negative (n=3) and HER2+ (n=3: 2 ER+, 1 ER-)...

The use of trastuzumab in patients with breast cancer that overexpresses human epidermal growth factor receptor 2 has significantly improved treatment outcomes. However, a substantial proportion of this patient group still experiences progression of the disease after receiving the drug. Evaluation of the changes in expression of the human epidermal growth factor receptors could be of interest. Monoclonal antibodies against the extracellular domain of the human growth factor receptors, 2, 3, and 4, have been raised, and specific and sensitive immunoassays have been established...

Fructose-1,6-bisphosphatase 1, a rate-limiting enzyme in gluconeogenesis, was recently shown to be a tumor suppressor. However, the functions of fructose-1,6-bisphosphatase 1 in the regulation of mitophagy and apoptosis remain unknown. Here, we investigated the effects of fructose-1,6-bisphosphatase 1 on mitophagy and apoptosis as well as their underlying mechanisms in breast cancer cells. In this work, the messenger RNA and protein expression of various molecules were determined by quantitative realtime polymerase chain reaction and western blot, respectively...

BACKGROUND: Reproductive factors are associated with risk of breast cancer, but the association with breast cancer survival is less well known. Previous studies have reported conflicting results on the association between time since last childbirth and breast cancer survival. We determined the association between time since last childbirth (LCB) and survival of women with premenopausal and postmenopausal breast cancers in Malaysia. METHOD: A historical cohort of 986 premenopausal, and 1123 postmenopausal, parous breast cancer patients diagnosed from 2001 to 2012 in University Malaya Medical Centre were included in the analyses...

Obesity is the most common metabolic disease whose prevalence is increasing worldwide. This condition is considered a serious public health problem due to associated comorbidities such as diabetes mellitus and hypertension. Perinatal morbidity related to obesity does not end with birth; this continues affecting the mother/infant binomial and could negatively impact on metabolism during early infant nutrition. Nutrition in early stages of growth may be essential in the development of obesity in adulthood, supporting the concept of "nutritional programming"...

BACKGROUND: BC200 is a long non-coding RNA expressed at high levels in the brain and elevated in a variety of tumour types. BC200 has a hypothesized role in translational regulation; however, to date the functional role of BC200 in both normal and diseased states remains poorly characterized. METHODS: Detailed BC200 expression analyses were performed in tumor cell lines, primary and non-tumorigenic cultured breast and lung cells, and a panel of normal human tissues by quantitative real-time PCR and confirmed by northern blot...

BACKGROUND: Personalizing treatment regimes based on gene expression profiles of individual tumors will facilitate management of cancer. Although many methods have been developed to identify pathways perturbed in tumors, the results are often not generalizable across independent datasets due to the presence of platform/batch effects. There is a need to develop methods that are robust to platform/batch effects and able to identify perturbed pathways in individual samples. RESULTS: We present Gene-Ranking Analysis of Pathway Expression (GRAPE) as a novel method to identify abnormal pathways in individual samples that is robust to platform/batch effects in gene expression profiles generated by multiple platforms...

Tumor necrosis factor-α (TNF-α) is a cytokine involved in the various physiopathological processes such as autoimmune disorders and inflammation related diseases. Some multidrug resistant (MDR) cancer cell lines including MCF-7/MX are more vulnerable to cytotoxic effects of TNF-α than their parental lines. In this study, breast cancer cell line MCF-7 and its MDR derivative MCF-7/MX were exposed to TNF-α afterward various downstream signaling mediators of TNF-α were analyzed. Although, treatment of MCF-7 cells with TNF-α activated NF-kB and caused RIP1 ubiquitination, TNF-α exposure led to JNK and RIP1 phosphorylation in MCF-7/MX cells...

Histological grade is one of the most commonly used prognostic factors for patients diagnosed with breast cancer. However, conventional grading has proven technically challenging, and up to 60% of the tumors are classified as histological grade 2, which represents a heterogeneous cohort less informative for clinical decision making. In an attempt to study and extend the molecular puzzle of histologically graded breast cancer, we have in this pilot project searched for additional protein biomarkers in a new space of the proteome...
