Few women with history of breast cancer and ovarian cancer take a recommended genetic test

UCLA HealthDr. Christopher ChildersOf the nearly 4 million women in the United States who have had either breast cancer or ovarian cancer, at least 1.5 million have a high risk of carrying certain types of genetic mutations that could increase their risk for additional cancers in the future.And although the mutations, including those that affect the BRCA1 and BRCA2 genes, can be identified through a simple blood or saliva test, more than 80 percent of those women have not taken the test or even discussed it with a health care provider, according to a new study from the  UCLA Fielding School of Public Health.The study is published online August 18 in the peer-reviewed Journal of Clinical Oncology.“Many of these women have inherited genetic changes that put them and their family members at risk for future cancers,” said Dr. Christopher Childers, a resident physician in the department of surgery at the David Geffen School of Medicine at UCLA and the study’s lead author. “Identifying a mutation is often important for surgical decision-making and cancer therapy, but its importance extends further than that. If individuals are aware that they have these mutations, they can take steps to lower their future cancer risk.”Childers said people who know they have the mutations would be advised to undergo more frequent and specialized screening (such as breast MRI), consider preventive medications, undergo risk-reducing surgery or mak...

Abstract BMI-1 (B-lymphoma Mo-MLV insertion region 1) is a key protein partner in polycomb repressive complex 1 (PRC1) that helps in maintaining the integrity of the complex. It is also a key player in ubiquitination of histone H2A which affects gene expression pattern involved in various cellular processes such as cell proliferation, growth, DNA repair, apoptosis and senescence. In many cancers, Overexpression of BMI1correlates with advanced stages of disease, aggressive clinicopathological behavior, poor prognosis resistance to radiation and chemotherapy. BMI1 is emerging as a key player in EMT, chemo-resistance...

However, its clinical application is limited by cardiotoxicity, such as cardiomyopathy, that once developed carries a poor prognosis and is frequently ...

Abstract Protein kinases are promising therapeutic targets for cancer therapy. Here, we applied multiple approaches to optimize the potency and selectivity of our reported alloxazine scaffold. Flexible moieties at position 2 of the hetero-tricyclic system were incorporated to fit into the ATP binding site and extend to the adjacent allosteric site and selectively inhibit protein kinases. This design led to potential selective inhibition of ABL1, CDK1/Cyclin A1, FAK, and SRC kinase by 30-59%. Cytotoxicity was improved by ∼50 times for the optimized lead (10b; IC50 = 40 nM) against breast cancer (MCF-7) ce...

CONCLUSION Cognitive impairment can affect daily functioning, quality of life, and capacity to work in patients with cancer and those in remission. Consequently, cognitive assessment is now an important and necessary part of a comprehensive oncological care plan. Cancer-related cognitive impairment might be due to the direct effects of the cancer itself, nonspecific factors, or comorbid conditions that are independent of the disease and/or due to the adverse effects of the treatment or combination of treatments given for the disease. The prevalence and extent of cognitive impairment associated with cancer is recognized but...

Osteopontin (OPN), a multifunctional protein, has emerged as a potentially valuable biomarker for diagnosing and treating cancers. Recent research focuses on its involvement in tumor biology including the cell proliferation, survival, angiogenesis, invasion, and metastasis. Understanding the molecular mechanisms and pharmacological effects of OPN in cancer development could lead to new targets for improving cancer diagnosis and treatment.This review explains how the structurally conserved domains of OPN are associated with OPN signaling mediators and CD44, and how the conserved OPN domains determine biological functions. T...

CONCLUSION: The current review suggests that random start ovarian stimulation can shorten the interval between ovarian stimulation and oocyte retrieval, with the yield of oocytes and embryos being comparable to conventional stimulation protocols. Thus, random start ovarian stimulation may serve as a better option for fertility preservation in patients requiring urgent cancer treatment. PMID: 28786354 [PubMed - as supplied by publisher]

Publication date: Available online 1 July 2017 Source:Prostaglandins, Leukotrienes and Essential Fatty Acids (PLEFA) Author(s): Mandi M. Hopkins, Kathryn E. Meier Many cellular actions of omega-3 fatty acids are mediated by two G protein-coupled receptors, FFA1 and FFA4, free fatty acid receptor (FFAR) family members that are activated by these dietary constituents. FFAR agonists inhibit proliferation of human prostate and breast cancer cells. Since omega-3 fatty acids can inhibit ovarian cancer cell growth, the current study tested the potential role of FFARs in the response. OVCAR3 and SKOV3 human ovarian cancer cell li...

Abstract Clinical trials and meta-analyses investigating bisphosphonates as an adjuvant breast cancer therapy have shown a consistent trend, with postmenopausal women and women receiving ovarian suppression with gonadotropin-releasing hormone therapy gaining improved breast cancer outcomes with the use of adjuvant bisphosphonate therapy. The interpretation of these data is controversial, because the primary endpoints of the majority of adjuvant bisphosphonate studies have been negative. Pros and cons as well as the value of adjuvant bisphosphonate therapy are discussed here. PMID: 28561722 [PubMed - in process]

Authors: Li X, Chen W, Wang H, Wei Q, Ding X, Li W Abstract Duplication in the chromosome 8q24 region is a frequent occurrence in carcinomas. The PVT1 oncogene (PVT1), a long non-coding RNA, is found in this locus. PVT1 amplification is a frequent event in cancers, such as in lymphomas, serous ovarian, colorectal and breast cancers. Ectopic PVT1 expression is related with reduced survival duration in cancer patients. in the present study, we proved that PVT1 is markedly augmented in breast cancer tissues compared with adjacent non-tumorous tissues. Thus, PVT1 is an independent prognostic factor for the survival dur...
