DSCAM-AS1 up-regulation in invasive ductal carcinoma of breast and assessment of its potential as a diagnostic biomarker.

CONCLUSIONS: The significant up-regulation of DSCAM-AS1 in tumoral tissues compared with ANCTs provides further evidences for participation of this lncRNA in the pathogenesis of breast cancer. PMID: 30594914 [PubMed - as supplied by publisher]

Conclusion: SRS, combined with SHG, can be a valuable tool in better understanding calcifications in carcinogenesis, diagnosis, and possible prognosis. This study not only reveals previously unknown large variations of breast microcalcifications in association with local malignancy but also corroborates the clinical value of linking microcalcification chemistry to breast malignancy. More importantly, it represents an important step in the development of a label-free imaging strategy for breast cancer diagnosis with tremendous potential to address major challenges in diagnostic discordance in pathology.

Purpose: Metaplastic breast cancer (BC) is an uncommon yet aggressive histologic subtype of BC. We sought to identify factors associated with its diagnosis and compare the management and outcomes of metaplastic BC with those of other BCs and triple negative invasive ductal carcinoma in particular given how often it has a triple negative phenotype.Patients and Methods: We identified women diagnosed with invasive BC in 2010-2014 in the National Cancer Data Base, and used univariate analysis to compare baseline patient and tumor characteristics by BC subtype. Overall survival (OS) was estimated with the Kaplan-Meier method, a...

We report a 69-year-old woman with spontaneous pneumothorax associated with cavitating pulmonary metastasis from breast cancer. She was treated for right breast cancer (invasive ductal carcinoma, ypT4bN1M0, stage IIIB) 2  years earlier, and was admitted for right pneumothorax and chest computed tomography, which showed multiple small cavitating lesions in bilateral lungs. The pneumothorax was treated conservatively with chest drainage, but subsequently recurred ipsilaterally. During video-assisted thoracic surgery, we detected small white nodules with visceral pleural rupture; therefore, we performed partial lung rese...

AbstractPurposeFunctional studies have demonstrated that gonadotropin-releasing hormone (GnRH) regulates cell proliferation, apoptosis, and tissue remodeling. GnRH is metabolized by the proteolytic regulatory enzyme pyrrolidone carboxypeptidase (Pcp) (E.C. 3.4.19.3), which is an omega peptidase widely distributed in fluids and tissues. We previously reported a decrease in both rat and human Pcp activity in breast cancer, suggesting that GnRH may be an important local hormonal factor in the pathogenesis of breast cancer. Recently, we have described that postmenopausal women with breast cancer show lower levels of serum Pcp ...

A previously healthy 36-year-old premenopausal woman with no known family history of breast cancer presented with palpable nodules in her left breast. Diagnostic mammogram and ultrasound demonstrated an 8 × 4 cm area of segmental pleomorphic calcifications with scattered masses in the left breast at 7 to 8 o’clock. A biopsy of the anterior and posterior left breast lesions showed an invasive ductal carcinoma. Intermediate nuclear grade estrogen and progesterone receptors stained positive (>90%), and human epidermal growth factor receptor 2 (HER2) was equivocal by fluorescence in situ hybridization.

This study investigated the impact of marital status on IDC patients. MATERIAL AND METHODS SEER databases were searched from 2010 to 2015 for subjects who were married, divorced, single, and widowed. The influence of marital status on breast cancer-specific survival (BCSS) and overall survival (OS) of IDC patients was investigated through multivariate Cox regression analysis and Kaplan-Meier analysis. To prevent bias, propensity score matching (PSM) analysis was performed. RESULTS The 5-year OS was 89.6%in married patients, 84.9% in divorced patients, 83.5% in single patients, and 71.3% in widowed patients (p

Plasma albumin to fibrinogen ratio is involved in human cancer, but its prognostic significance in breast cancer is controversy. In the context of breast invasive ductal carcinoma, this research aims to retrospectively evaluate by preoperative plasma albumin to fibrinogen ratio (AFR) and forecast oncological outcome and recurrence. This retrospective study comprised 230 patients with non-metastatic breast invasive ductal carcinoma who underwent surgery between January 2009 and April 2012 in Fourth Hospital of Hebei Medical University. Patients were categorized base on an optimal value of preoperative plasma fibrinogen (Fi...
