A low level of breast cancer metastasis suppressor 1-like (BRMS1L) has been implicated in tumour metastasis involving breast cancer and other cancers. It remains unclear whether BRMS1L is involved in epithelial ovarian cancer (EOC) metastasis and what the molecular mechanism of BRMS1L is in suppressing EOC metastasis. In this study, we examined the mRNA expression and protein level of BRMS1L by screening EOC patients. Our results show that BRMS1L expression is downregulated in EOC patients compared to that in normal people and negatively correlated to pathological stages of EOC...

Quinolines, indolizines, and coumarins are well known structural elements in many biologically active molecules. In this report, we have developed straightforward methods to incorporate quinoline, indolizine, and coumarin structures into galactoside derivatives under robust reaction conditions for the discovery of glycomimetic inhibitors of the galectin family of proteins that are involved in immunological and tumor-promoting biological processes. Evaluation of the quinoline, indolizine and coumarin-derivatised galactosides as inhibitors of the human galectin-1, 2, 3, 4N (N-terminal domain), 4C (C-terminal domain), 7, 8N, 8C, 9N, and 9C revealed quinoline derivatives that selectively bound galectin-8N, a galectin with key roles in lymphangiogenesis, tumor progression, and autophagy, with up to nearly 60-fold affinity improvements relative to methyl β-d-galactopyranoside...

Trastuzumab and pertuzumab are monoclonal antibodies used for the treatment of breast cancer. Until now, there have been no reports on the use of pertuzumab during pregnancy and on its potential effects on the fetus. Herein, we present a breast cancer patient who received trastuzumab and pertuzumab treatment during the first 20 weeks of pregnancy. This 22-year-old patient initially diagnosed with invasive ductal carcinoma of the breast was found to be negative for estrogen receptor and progesterone receptor and positive for human epidermal growth factor receptor in the immunohistochemical examination...

BACKGROUND: When a breast lesion is suspected based on a physical exam, mammography, or ultrasound, a stereotactic core needle biopsy (CNB) is usually performed to help establish a definitive diagnosis. CNBs are far less invasive than excisional biopsies, with no need for general anesthetics or hospitalization, and no recovery period. However, since only samples of the mass are removed in a CNB and not the whole mass, sampling errors can occur. OBJECTIVES: To compare the degree of agreement between the pathological data from CNBs and excisional biopsies from a single tertiary referral hospital...

Increased F18-FDG uptake is on PET-CT images should always be assessed carefully for physiological and pathological causes. Breast uptake may be focal or diffuse. Although propensity of tumours increase in focal uptake; diffuse involvement may be seen in lymphoma and some types of breast cancer. Frequently, diffuse breast uptake is non-pathologic due to infection, physiological uptake or lactation. We describe the case of a 27-years old female who underwent 18F FDGPET-CT scan for staging workup of diffuse large B-cell lymphoma (DLBCL)...

BACKGROUND: Breast cancer is the most common malignancy in women worldwide. Although the endocrine therapy that targets estrogen receptor α (ERα) signaling has been well established as an effective adjuvant treatment for patients with ERα-positive breast cancers, long-term exposure may eventually lead to the development of acquired resistance to the anti-estrogen drugs, such as fulvestrant and tamoxifen. A better understanding of the mechanisms underlying antiestrogen resistance and identification of the key molecules involved may help in overcoming antiestrogen resistance in breast cancer...

INTRODUCTION: Neoadjuvant chemotherapy has become the treatment of choice for locally advanced breast cancer. Zoledronic acid (ZA) is a bisphosphonate initially used in the treatment of bone metastases because of its antibone resorption effect. Antitumor effects of ZA, including the inhibition of cell adhesion to mineralized bone or the antiangiogenic effect, have been demonstrated. However, the clinical significance of these effects remains to be determined. MATERIALS AND METHODS: We undertook a multicenter open-label randomized trial to analyze the value of adding ZA to neoadjuvant chemotherapy for TNM clinical stage T2/T3 breast cancer...

BACKGROUND: Cervical cancer screening will inevitably lead to unintentional harmful effects e.g. detection of indolent pathological conditions defined as overdetection or overdiagnosis. Overdiagnosis often leads to overutilisation, overtreatment, labelling and thereby negative psychosocial consequences. There is a lack of adequate psychosocial measures when it comes to measurement of the harms of medical screening. However, the Consequences of Screening questionnaire (COS) has been found relevant and comprehensive with adequate psychometric properties in breast and lung cancer screening...

Histopathology images are used for the diagnosis of the cancerous disease by the examination of tissue with the help of Whole Slide Imaging (WSI) scanner. A decision support system works well by the analysis of the histopathology images but a lot of problems arise in its decision. Color variation in the histopathology images is occurring due to use of the different scanner, use of various equipments, different stain coloring and reactivity from a different manufacturer. In this paper, detailed study and performance evaluation of color normalization methods on histopathology image datasets are presented...
