MicroRNAs are emerging as critical regulators of the initiation and progression of multiple types of human cancers, including breast cancer. In the present study, the expression of miR-181b in breast cancer patient serum and breast cancer cell lines was evaluated. It was demonstrated that the miR-181b level was significantly upregulated in patient serum and(More)
Monitoring recurrence and evaluating response to therapy are important aspects of clinical decision making in the treatment of breast cancer. In this literature review, the authors highlight several of the key areas where integrated fluorine-18 fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT) measurements are anticipated to(More)
PURPOSE Pancreatic carcinoma is a malignant tumor with poor prognosis and its early detection is still a clinical problem. The aim of this study was to evaluate the efficacy of carbon-11-labeled acetate (11C-acetate)-positron emission tomography (PET) for the detection of pancreatic carcinoma in a BxPC-3 human pancreatic carcinoma xenograft-bearing(More)
BACKGROUND Mucinous breast carcinoma (MC) is a special type of breast cancer that presents with a large amount of extracellular mucin. MC comprises approximately 4% of all invasive breast cancers. This type of tumor has a better prognosis and higher incidence in peri- and post-menopausal patients. Pathologically, there are two main subtypes of MC: pure and(More)
The aim of the present study was to establish the underlying regulatory mechanism of estrogen receptor (ER) in breast cancer cell gene expression. A gene expression profile (accession no. GSE11324) was downloaded from the Gene Expression Omnibus (GEO) database. Differentially expressed genes (DEGs) from an estrogen treatment group and a control group were(More)
We examined the long-term clinical tolerance and cardiac safety of trastuzumab treatment in ninety-four female patients diagnosed with breast cancer with human epidermal growth factor receptor 2 (HER-2) overexpression. Electrocardiography (ECG) was monitored throughout trastuzumab treatment, and left ventricular ejection fractions (LVEFs) were estimated(More)
PURPOSE Aromatase, encoded by the CYP19 gene, catalyzes the final step of the conversion of androgens to estrogens. Given the critical role of CYP19 in estrogen synthesis, the potential influence of CYP19 rs4646 polymorphism on breast cancer survival, deserves further study. METHODS Genotyping for CYP19 rs4646 variants was performed on 406 Chinese women(More)
CONTEXT Breast cancer becomes more prevalent with advancing age. The increased risk of breast cancer needs to be considered when choosing a treatment plan and a kind of detection method for the postmenopausal woman. Better breast cancer prognostication may improve selection of patients for adjuvant therapy. AIMS The aim of this study is to investigate the(More)
RATIONALE Breast cancer is the most prevalent malignancy in women worldwide. Our patient presented with a history of breast liposarcoma (LPS) and was found to have pleural metastasis during the initial workup. PATIENT CONCERNS The patient was complaining about chest pain and dyspnea that had persisted for a week. DIAGNOSES After a full evaluation and(More)
PURPOSE The aim was to verify the potential association between CYP19A1 genetic polymorphisms and clinical outcome of hormone therapy in hormone receptor (HR)-positive early breast cancer. METHODS Genotyping for CYP19A1 rs4646 (C/A) polymorphism was performed on 287 women with HR-positive early breast cancer. Associations were evaluated between CYP19A1(More)
