Genetic testing could improve breast cancer prevention — ScienceDaily

Their study showed that prevention strategies could be improved by testing not only as currently for major cancer predisposition genes such as BRCA1 and BRCA2 — which identify a small percentage of women at very high risk — but also by factoring in data on multiple gene variants that individually have only a small effect on risk, but are more common in the population. The research was carried out by researchers at The Institute of Cancer Research, London, and the National Cancer Institute in Bethesda, US — and is published in the Journal of the National Cancer Institute. The study received funding from The Institute of Cancer Research (ICR), Breakthrough Breast Cancer and the National Cancer Institute. Researchers stressed that their study was a computer modelling analysis and would need to be confirmed by further research aimed at validating the models they used and assessing real-life prevention approaches…

Britain’s obese in denial about their weight

In one of the first studies of its kind to examine British perceptions of obesity, fewer than 10 per cent of those who are clinically obese accept they have a serious weight problem. In a 2012 survey of around 2000 adults, only 11 per cent of obese women accurately acknowledged they were “obese,” with most describing themselves as “very overweight” or “just right.” And among men, only seven per cent correctly described themselves as being “obese” and another 16 per cent as “very overweight.” Approximately 10 per cent of people in the survey knew the BMI threshold for obesity and those who did were more likely to define themselves as “obese.” Researchers suggest that as bigger sizes become the new “normal,” people are less likely to recognise the health problems associated with their weight. Professor Jane Wardle, co-author and director of the Cancer Research UK Health Behaviour Centre at UCL, said: “It’s a real worry that people don’t recognise that their weight places them in the obese category, because it means they aren’t aware they are at increased risk of a number of health problems including cancer. …

Dscovery may help breast cancer treatment — ScienceDaily

Triple negative breast cancers (TNBCs) have a high mortality rate owing to aggressive proliferation and metastasis and a lack of effective therapeutic options. However, Professor Auguste’s team, discovered the overexpression of intercellular adhesion molecule-1 (ICAM-1) in human TNBC cell lines and tissues, and demonstrated that it is a potential molecular target and biomarker for TNBC therapy and diagnosis. “No therapies are available to treat triple negative breast cancer cells and because of that patients have a poor prognosis,” said Professor Auguste, the recipient of a 2014 Presidential Early Career Award for Scientists and Engineers. The Identification of ICAM-1 as a TNBC target and biomarker may lead to the development of a new strategy and platform for addressing a critical gap in TNBC patient care, she added. …

Olaparib shows success in tumor response rate for patients with BRCA-related cancers

For the majority of patients in the study, olaparib was at least their third different cancer therapy. Based on the new data, the authors say olaparib warrants further investigation in phase III trials. The positive response in metastatic pancreatic cancer patients who had received an average of two prior rounds of chemotherapy is an especially noteworthy finding since therapeutic options for these patients are limited. …

Breast cancer recurrence: Study provides insight

Around 5,000 cases of DCIS, a condition where cancerous cells are contained within the milk ducts of the breast, are diagnosed each year in the UK, with two thirds diagnosed through breast screening. If left untreated, up to half of DCIS cases could progress into invasive breast cancer, but it is not possible to say which ones, so all women are offered treatment. This usually involves breast-conserving surgery (lumpectomy) and, to reduce the risk of the cancer returning, radiotherapy to kill any remaining cancer cells. However, even with treatment up to one in five patients will see their DCIS come back, either as DCIS or as invasive breast cancer. …

Gene ‘switches’ could predict when breast cancers will spread to the brain

The researchers, based at the University of Wolverhampton, studied 24 breast cancers that had spread to the brain, along with samples from the original breast tumour, and found a handful of genes with faulty switches. Crucially, two of the genetic switches became faulty early on in the development of breast cancer, suggesting they may be an early warning signal for tumours that will spread to the brain. The scientists are now working to develop a blood test that might be able to detect these signals at an early stage, before the disease has spread. Up to 30 per cent of breast cancers will eventually spread to the brain, often many years after the first tumour was treated…

Sea sponge drug could boost advanced breast cancer survival by five extra months — ScienceDaily

Researchers led by Professor Chris Twelves, based at the University of Leeds and Leeds Teaching Hospitals NHS Trust, looked at two major clinical trials of more than 1,800 women with breast cancer that had started to spread to other parts of the body. The phase III trials — the final stage of testing before deciding whether a drug can be prescribed to patients — compared the survival of women treated with eribulin to those given standard treatment…

Comprehensive breast center improves quality of care for breast reconstruction — ScienceDaily

Centralized breast cancer care at CBCs can lead to more timely breast reconstruction for women undergoing breast cancer surgery, suggests the study by ASPS Member Surgeon Albert H. Chao, MD, and colleagues of The Ohio State University, Columbus. They write, “Access to breast reconstruction at our institution improved significantly after our CBC opened, with significant increases in internal referral rates and immediate reconstruction rates.” Transition to CBC Improves Processes of Care The researchers assessed “process of care” outcomes related to breast reconstruction before and after their hospital transitioned to a CBC approach. Comprehensive breast centers seek to improve patient care and outcomes by assembling a group of highly specialized practitioners — oncologists, plastic and reconstructive surgeons, and other professionals — to provide coordinated breast cancer care…
