Many patients in cancer centers may not experience a dignified death

Previous research has shown that hospitals are often ill-prepared to provide care for dying patients. To investigate whether the circumstances for dying on cancer center wards allow for a dignified death, Karin Jors, MA, of the University Medical Center Freiburg, and her colleagues surveyed physicians and nurses in 16 hospitals belonging to 10 cancer centers in Baden-W�rttemberg, Germany. The survey addressed topics regarding end-of-life care including structural conditions such as rooms and staff, education/training, working environment, family/caregivers, medical treatment, communication with patients, and dignified death. Among 1131 survey respondents, 57 percent believed that patients could die with dignity on their ward. …

New genetic target for a different kind of cancer drug found — ScienceDaily

“Historically, scientists haven’t targeted the proteins in cancer cells that are involved in gene splicing,” said Zefeng Wang, PhD, associate professor in the department of pharmacology and senior author of the Cancer Cell paper. “This is a whole new ballgame in terms of gene regulation in cancer.” There are approximately 25,000 genes in the human genome — the same amount as in a fruit fly. But in humans, these genes are spliced together in different ways to create various kinds of messenger RNA to produce the many different proteins humans require. It’s like a filmmaker splicing together bits of movie scenes to create alternative cuts of a movie…

Common diabetes drug not linked to short-term risk of pancreatic cancer

“Our research shows that short-term use of DPP-4 inhibitors in older diabetes patients does not increase their risk for pancreatic cancer,” said John Buse, MD, PhD, director of the Diabetes Care Center at UNC and co-author of the paper in the current issue of the journal Diabetes, Obesity and Metabolism. “However, we just cannot address the long-term safety, yet. There are just not enough people who have taken the drug for many years.” DPP-4 inhibitors came on the market in 2006. Since then, these drugs have become some of the most commonly prescribed diabetes medications, primarily because they often cause fewer side effects compared to other diabetes treatments…

New antifungal as effective as existing drugs with fewer adverse events

“There is a growing need for new antifungal therapies like isavuconazole because serious fungal infections caused by Aspergillus and other molds are on the rise due to the increasing numbers of immunosuppressed patients, including those with active cancer. These infections are associated with high morbidity and mortality. If approved, isavuconazole has the potential to be an important new option for the treatment of these life-threatening fungal infections,” says Andrew Ullman of Julius Maximilians University in Wuerzburg, Germany, one of the researchers presenting data. Invasive fungal infections are important causes of morbidity and death for patients with hematological malignancies…

Ultraviolet light-induced mutation drives many skin cancers, researchers find

The mutation occurs in a gene called KNSTRN, which is involved in helping cells divide their DNA equally during cell division. Genes that cause cancer when mutated are known as oncogenes. Although KNSTRN hasn’t been previously implicated as a cause of human cancers, the research suggests it may be one of the most commonly mutated oncogenes in the world. “This previously unknown oncogene is activated by sunlight and drives the development of cutaneous squamous cell carcinomas,” said Paul Khavari, MD, PhD, the Carl J…

No association found between wearing bra, breast cancer — ScienceDaily

“There have been some concerns that one of the reasons why breast cancer may be more common in developed countries compared with developing countries is differences in bra-wearing patterns,” said Lu Chen, MPH, a researcher in the Public Health Sciences Division at Fred Hutchinson Cancer Research Center and a doctoral student in the Department of Epidemiology at the University of Washington School of Public Health. “Given how common bra wearing is, we thought this was an important question to address. …

Novel immunotherapy vaccine decreases recurrence in HER2 positive breast cancer patients — ScienceDaily

One of only a few vaccines of its kind in development, GP2 has been shown to be safe and effective for breast cancer patients, reducing recurrence rates by 57%. Further, women with the highest overexpression of HER2 (known as HER2 +3) had no cancer recurrences when they were administered the vaccine after completing trastuzumab (Herceptin), a type of immunotherapy drug known as a monoclonal antibody. HER2 is an oncoprotein that promotes tumor growth and is expressed to some extent in 75-80% of breast cancers. “This is an important and different avenue in immunotherapy research, in that we are investigating ways to prevent cancer recurrence by stimulating the immune system to treat cancer,” says principal investigator Elizabeth Mittendorf, M.D., Ph.D., associate professor of Surgical Oncology…

Soy supplementation adversely effects expression of breast cancer-related genes

The impact of soy consumption on breast cancer prevention and treatment is not clear although many women believe soy supplementation is beneficial based primarily on results from epidemiological studies. Moshe Shike, M.D., from the Department of Medicine at Memorial Sloan-Kettering Cancer Center and Weill Cornell Medical College in New York, NY, and colleagues conducted a randomized placebo-controlled study of the effects of soy supplementation on gene expression and markers of breast cancer risk among women diagnosed with invasive breast cancer. The study, run between 2003 and 2007 at Memorial Sloan-Kettering, enrolled a total of 140 patients who were randomized to either soy supplementation (soy protein) or placebo (milk protein), which lasted from the initial surgical consultation to the day before surgery (range=7-30 days). Tumor tissues from the diagnostic biopsy (pre-treatment) and at the time of resection (post-treatment) were then analyzed. …

‘Prepped’ by tumor cells, lymphatic cells encourage breast cancer cells to spread — ScienceDaily

Writing in the Sept. 2 issue of Nature Communications, the researchers describe animal and cell-culture experiments that show increased levels of so-called signaling molecules released by breast cancer cells. These molecules cause lymphatic endothelial cells (LECs) in the lungs and lymph nodes to produce proteins called CCL5 and VEGF. CCL5 attracts tumor cells to the lungs and lymph nodes, and VEGF increases the number of blood vessels and makes them more porous, allowing tumor cells to metastasize and infiltrate the lungs. …
