New breast cancer test links immune ‘hotspots’ to better survival

Researchers used statistical software previously used in criminology studies of crime hotspots to track the extent to which the immune system was homing in and attacking breast cancer cells. The test, described in the journal Modern Pathology, could assess whether a woman’s immune system is holding a cancer at bay — and pick out those who will need intensive treatment to combat their more aggressive disease. Scientists at The Institute of Cancer Research, London, analysed tumour samples from 245 women with a type of breast cancer called oestrogen receptor negative (ER negative), which is particularly hard to treat. …

New tool provides maps of protein interactions for 2,800 diseases

Scientists working in the Structural Bioinformatics and Network Biology Lab have included the more than 23,000 documented genetic mutations that affect the function of 2,000 proteins in an open-access web tool, and have positioned them on the map of known interactions between human proteins. dSysMap can be accessed free of charge at http://dsysmap.irbbarcelona.org, and scientists from around the world can add their data in an anonymous manner. Developed entirely at IRB Barcelona, dSysMap (“Disease-mutations Systemic Mapping”) provides molecular details about how mutations in certain proteins alter interactions with other proteins, thus affecting the correct funcion of cellular processes. The tool has explained, for example, why mutations in a single protein can cause two distinct diseases or why mutations in different proteins can trigger the same condition. …

Anderson algorithm increases surgical success with advanced ovarian cancer

The researchers describe the Anderson Algorithm in a perspective piece outlining a personalized surgical approach to ovarian cancer published online at Nature Reviews Clinical Oncology. “Our algorithm allows us to be much smarter about whom we operate on up front, providing a more individualized approach to surgery that’s led to better results for our patients,” said Anil Sood, M.D., professor of Gynecologic Oncology and Reproductive Medicine and senior author of the paper. The multi-step process was developed through MD Anderson’s Moon Shots Program, an ambitious effort launched in 2012 to dramatically reduce cancer deaths. Sood is co-leader of the Breast and Ovarian Cancer Moon Shot…

Chemotherapy after bladder cancer surgery may improve survival

Clinical trials have established the benefit of giving chemotherapy prior to surgery (neoadjuvant chemotherapy) for patients with bladder cancer. However, clinical trials exploring giving chemotherapy after surgery (adjuvant chemotherapy) have been difficult to interpret and many of the trials closed early due to poor accrual without providing an answer. Lead researcher Matthew Galsky, MD and colleagues used a large database of patients diagnosed with cancer in the United States. Specifically, the study found that patients receiving adjuvant chemotherapy after surgical treatment had improved overall survival when compared to patients that received surgical treatment alone with only post-surgical observation. …

Mammography screening: Patient pamphlets do not affect willingness to participate

In Germany, the invitation to undergo mammography screening that is sent to all women between the ages of 50 and 69 is accompanied by an information leaflet explaining the advantages and disadvantages of screening. In this issue of Deutsches �rzteblatt International, Elisabeth Gummersbach and colleagues report on a study in which they determined how well the prospective subjects understood the information presented and whether this information influenced their willingness to undergo screening. It was found that the leaflet itself made little or no difference to the women’s willingness to participate. Rather, the most important factor in the decision whether to be screened was usually a doctor’s personal recommendation…

Gene that pushes normal pancreas cells to change shape identified

Their findings, reported in Nature Communications, suggest that inhibiting the gene, protein kinase D1 (PKD1), and its protein could halt progression and spread of this form of pancreatic cancer, and possibly even reverse the transformation. “As soon as pancreatic cancer develops, it begins to spread, and PKD1 is key to both processes. Given this finding, we are busy developing a PKD1 inhibitor that we can test further,” says the study’s co-lead investigator, Peter Storz, Ph.D., a cancer researcher at Mayo Clinic…

Women back idea of more breast screens for those at high risk of cancer

Fewer women (60 per cent) would be happy to be screened less often if they were found to be at lower risk. More than 940 women from across the UK were asked for their views on the possibility of tailoring breast screening to people’s genetic risk in a study funded by Cancer Research UK and The Eve Appeal…

Key indicator for successful treatment of infertile couples

“As a woman approaches menopause, her level of follicle stimulating hormone (FSH) rises,” explained Goldman. “A higher FSH level is a key indicator that the woman may not be as fertile as necessary to conceive using certain common methods of infertility treatment.” The study determined if FSH and estrogen at the upper limits of normal, as measured on day three of the menstrual cycle, could predict treatment success as measured in live birth rates…
