Breast cancer rarely metastasizes to the uterus. Here, we report two breast cancer patients with synchronous metastases to the uterus. Case 1 highlights a 46-year-old female with invasive ductal carcinoma who presented with a breast mass and was found to have uterine enlargement on positron emission tomography (PET) scan. Biopsy revealed a metastatic 4 mm focus of breast cancer in the background of endometrial hyperplasia. Case 2 reports a 62-year-old postmenopausal female diagnosed with lobular carcinoma of the breast following an abnormal screening mammogram...

There has been tremendous progress in detection of breast cancer in postmenopausal women, resulting in two-thirds of women surviving more than 20 years after treatment. However, breast cancer remains the leading cause of cancer-related deaths in premenopausal women. Breast cancer is increasing in younger women due to changes in life-style as well as those at high risk as carriers of mutations in high-penetrance genes. Premenopausal women with breast cancer are more likely to be diagnosed with aggressive tumours and therefore have a lower survival rate...

Availability of tumor and non-tumor patient-derived models would promote the development of more effective therapeutics for Non Small Cell Lung Cancer (NSCLC). Recently, conditionally reprogrammed cells (CRC) methodology demonstrated exceptional potential for the expansion of epithelial cells from patient tissues. However, the possibility to expand patient-derived lung cancer cells using CRC protocols is controversial. Here, we used CRC approach to expand cells from non-tumoral and tumor biopsies of patients with primary or metastatic NSCLC as well as pulmonary metastases of colorectal or breast cancers...

N-acetyltransferase 1 (NAT1) is an enzyme which metabolizes carcinogens suggesting a potential role in breast carcinogenesis. High NAT1 expression in breast tumors is associated with estrogen receptor α (ERα+) and the luminal subtype. We report that NAT1 mRNA transcript, protein, and enzyme activity were higher in human breast tumors with high expression of ERα/ESR1 compared to normal breast tissue. There was a strong correlation between NATb promoter and NAT1 protein expression/enzyme activity. High NAT1 expression in tumors was not due to adipocytes as evidenced by low PLIN expression...

BACKGROUND: Current preoperative cardiac risk stratification practices group operations into broad categories, which might inadequately consider the intrinsic cardiac risks of individual operations. We sought to define the intrinsic cardiac risks of individual operations and to demonstrate how grouping operations might lead to imprecise estimates of perioperative cardiac risk. METHODS: Elective operations (based on Common Procedural Terminology codes) performed from January 1, 2010 to December 31, 2015 at hospitals participating in the American College of Surgeons National Surgical Quality Improvement Program were studied...

Recurrent breast cancer poses considerable diagnostic and therapeutic challenges for clinic. Clinical suspicion of recurrence must be first confirmed by imaging studies. Then re-biopsy of suspected recurrence and metastasis in patients with breast cancer is recommended in the practice guidelines of the National Comprehensive Cancer Network (NCCN) and European Society for Medical Oncology (ESMO) to confirm whether the molecular subtype changes. It may change the individual treatment plan directly. Our research provided an integrated algorithm for locally recurrent or distant metastatic breast cancer, including early relapse detection and subsequently a new practical PET/CT imaging guide biopsy approach for surveilling molecular subtype shifts of the recurrent breast cancer...

BACKGROUND: Phyllodes tumors (PT) are uncommon biphasic tumors, accounting for less than 1% of all breast primary neoplasms. They form a wide variety of tumors ranging from benign to malignant. Several histological features are used to grade PT into 3 categories: benign (grade I), borderline (grade II) and malignant (grade III) tumors. The aim of our study was to analyse histolopathological, radiological and clinical features of PT from an experience of a single center. METHODS: It was a retrospective study including 106 patients diagnosed with phyllodes tumors on surgical specimens at the department of pathology, of Hassan II university hospital (Fez, Morocco), from 2009 to 2016...

Alcohol consumption likely induces gastric carcinogenesis through deregulation of RNA polymerase (Pol) III genes and oxidative damage. Transcription factor IIB-related factor 1 (BRF1) overexpression alleviates RNA Pol III transcription inhibition through breast cancer susceptibility gene 1 (BRCA1). Myeloperoxidase (MPO) involvement in cancer is induced by alcohol-mediated oxidative damage. BRCA1/2 and MPO play key roles in DNA repair. BRCA1 and BRCA2 exert different roles in homologous recombination repair...

Increased uptake of glucose, a general hallmark of malignant tumors, leads to an accumulation of intermediate metabolites of glycolysis. We investigated whether the high supply of these intermediates promotes their flow into UDP-sugars, and consequently into hyaluronan, a tumor-promoting matrix molecule. We quantified UDP-N-Acetylglucosamine (UDP-GlcNAc) and UDP-glucuronic acid (UDP-GlcUA) in human breast cancer biopsies, the levels of enzymes contributing to their synthesis, and their association with the hyaluronan accumulation in the tumor...

BACKGROUND: Intraoperative frozen sections (FS) of sentinel lymph nodes (SLN) were evaluated to avoid the need for deferred axillary lymph node dissection (ALND) in patients with early breast cancer (EBC). However, FS has low sensitivity for detecting micro-metastases (<2 mm), resulting in patients who later undergo deferred ALND. The aim of the study was to determine the best clinical approach for selecting patients who would derive real benefit from ALND, as well as to minimize the functional and psychological damage caused by delayed surgery, and the risk of undertreating EBC patients...
