Prostate cancer is the second most common cancer in American men, after skin cancer, according to the American Cancer Society (ACS). The ACS projects more than 27,000 deaths from prostate cancer in 2015 and is the second leading cause of cancer death in American men, behind lung cancer. One man in seven will be diagnosed with prostate cancer during his lifetime…
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…
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…
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…
“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…
“The FDA approval has expanded treatments options for many metastatic breast cancer patients, but these new results are showing how effective the drug can also be for breast cancer patients who have already tried endocrine therapies and may be running out of options,” said lead investigator Angela DeMichele, MD, MSCE, associate professor in the division of Hematology/Oncology and Epidemiology and co-leader of the Breast Cancer Research Program at the Abramson Cancer Center. “Combined with the promising results from other trials looking at the effectiveness of this drug, our results indicate that palbociclib can extend the duration of disease control and produce tumor shrinkage in patients with estrogen-receptor positive (ER+) breast cancer, without the debilitating side effects of chemotherapy.” The newly-published phase II trial primarily sought to evaluate disease response and control, while monitoring for the presence of side effects such as neutropenia, an abnormally low white blood cell count. Patients enrolled in the trial had previously undergone several prior chemotherapy and hormonal regimens for metastatic disease…
Their paper, “Interplay Between VEGF-A and cMET Signaling in Human Vestibular Schwannomas and Schwann Cells,” by Sonam Dilwali, B.S., Daniel Roberts, M.D., Ph.D., and Konstantina M. Stankovic, M.D., Ph.D., FACS, is online in the Feb. 20 issue of Cancer Biology and Therapy. …
For the study, Gabriella Hobbs, MD, and Nancy Keating, MD, MPH, of Harvard Medical School, and their colleagues surveyed 5284 patients with a new diagnosis of lung or colon cancer, and asked participants how they involved their families in decisions about their care. Only 1.5 percent of patients reported family-controlled decisions. Among the remaining patients, 49.4 percent reported equally sharing decisions with family, 22.1 percent reported some family input, and 28.5 percent reported little or no input from their families. Non-English speaking Asian patients and Spanish-speaking Hispanic patients were more likely to report equally shared decisions with their families than other patients. …
In preclinical studies using rodents, they found that stem cells transplanted one week after the completion of a series of chemotherapy sessions restored a range of cognitive functions, as measured one month later using a comprehensive platform of behavioral testing. In contrast, rats not treated with stem cells showed significant learning and memory impairment. The frequent use of chemotherapy to combat multiple cancers can produce severe cognitive dysfunction, often referred to as “chemobrain,” which can persist and manifest in many ways long after the end of treatments in as many as 75 percent of survivors — a problem of particular concern with pediatric patients. “Our findings provide the first solid evidence that transplantation of human neural stem cells can be used to reverse chemotherapeutic-induced damage of healthy tissue in the brain,” said Charles Limoli, a UCI professor of radiation oncology…
Study lead Menashe Bar-Eli, Ph.D., professor of Cancer Biology, reported a previously unknown target for CREB (cAMP response element-binding protein), a transcription factor that regulates other transcription factors involved in melanoma development. …
