Lung cancer risk model refines decisions to screen

Computed Tomography (CT) screening can identify lung tumors while they are still treatable, and the US National Lung Screening Trial (NLST) found that annual screening of high-risk smokers can reduce lung cancer mortality by 20%. The best way to identify those at high risk remains an important question. …

More breast cancer patients opting for mastectomy — ScienceDaily

The rates of increase were steepest among women with lymph node-negative and in situ (contained) disease. This is a reversal of trends seen since the 1990s when breast conservation surgery (BCS) was found to produce equivalent cancer outcomes and was endorsed as a standard of excellence by a National Institutes of Health Consensus Conference. The Vanderbilt University study, led by Kristy Kummerow, M.D., and Mary Hooks, M.D., MBA, was published online in the Nov. …

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…

Promising anti-cancer activity in experimental drug: Next-gen melanoma drug, TAK-733, excels in lab tests

“The importance of this molecule is that it’s a next-generation and highly potent inhibitor of a known melanoma pathway. It was highly effective against melanoma and the method of our study — using patient-derived tumor samples grown in mice — makes us especially optimistic that we should see similar results in the human disease,” says John Tentler, PhD, investigator at the CU Cancer Center, associate professor at CU School of Medicine and one of the paper’s lead authors…

Classification of gene mutations in a children’s cancer may point to improved treatments

“Some mutations are more important than others,” said Ya�l P. Moss�, MD, a pediatric oncologist at The Children’s Hospital of Philadelphia, and a co-leader of the new study published online today in the journal Cancer Cell. “By integrating biochemistry into our clinical strategies, we can better match a patient’s specific ALK-mutation profile with an optimum treatment.” Moss� is also an assistant professor of Pediatrics in the Perelman School of Medicine, University of Pennsylvania. “Understanding the specific mutations that trigger signals in cell receptors to stimulate cell growth will help us identify biomarkers for specific subtypes of neuroblastoma,” said study co-leader Mark A…

Half of premature colorectal cancer deaths due to socioeconomic inequality

Colorectal cancer (CRC) is the third leading cause of cancer death for both men and women in the U.S. Historically, death rates were higher in those with higher socioeconomic status, in whites, and in northern states. Over the past few decades, though, that switched, with death rates now highest in persons with the lowest socioeconomic status, in blacks, and in southern states…

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…
