Early palliative care can cut hospital readmissions for cancer patients

The Duke researchers shared their findings at the Palliative Care in Oncology Symposium sponsored by the American Society of Clinical Oncology. In the new treatment model, medical oncologists and palliative care physicians partnered in a “co-rounding” format to deliver cancer care for patients admitted to Duke University Hospital’s solid tumor unit. The Duke model fostered collaboration and communication between the specialists, who met several times a day to discuss patient care…

Artificial light, biological clock disruptions, increase breast cancer risk, study finds

“Exposure to artificial light leads to a significantly higher risk for developing breast cancer,” said Chunla He, a biostatistics graduate student in the UGA College of Public Health. “To decrease the use of artificial light, people should avoid working at night and implement earlier bed times.” Her research, published in the International Archives of Occupational and Environmental Health, examined key studies that included risk factors for developing breast cancer. …

Selenium effective treatment against breast cancer, study suggests — ScienceDaily

Julian Spallholz, a professor of nutritional sciences at Texas Tech University, has studied the effects of selenium on several types of cancer. His research on attaching selenium to the leading clinical chemotherapeutic monoclonal antibody for a type of breast cancer shows it can more effectively kill the cancer cells, he reports…

Artificial light, Biological clock disruptions, increase breast cancer risk, study finds — ScienceDaily

“Exposure to artificial light leads to a significantly higher risk for developing breast cancer,” said Chunla He, a biostatistics graduate student in the UGA College of Public Health. “To decrease the use of artificial light, people should avoid working at night and implement earlier bed times.” Her research, published in the International Archives of Occupational and Environmental Health, examined key studies that included risk factors for developing breast cancer. “A large body of related research about circadian rhythms and breast cancer exists,” He said. “However, these studies are inconsistent and have a variety of limitations.” Under the mentorship of Sara Wagner Robb, assistant professor of epidemiology in the College of Public Health, He turned to previous studies to see what the research revealed. …

Many older people have mutations linked to leukemia, lymphoma in their blood cells

Mutations in the body’s cells randomly accumulate as part of the aging process, and most are harmless. For some people, genetic changes in blood cells can develop in genes that play roles in initiating leukemia and lymphoma even though such people don’t have the blood cancers, the scientists report Oct…

Human cancer prognosis related to newly identified immune cell

The research is published online October 16, 2014 in the journal Cancer Cell. Molecules associated with these cells, newly identified by the UCSF researchers, could be the focus of new immunotherapies that are more precisely targeted than current immunotherapies now in clinical trials, said Matthew Krummel, PhD, professor of pathology at UCSF and the leader of the study. In fact, the UCSF researchers concluded that the presence of these cells may be the reason current immunotherapies aimed at boosting T lymphocyte responses have any effectiveness whatsoever. Krummel’s lab team depleted the population of these already rare cells in mice and demonstrated that the immune system was then unable to control tumors, even when the mice were given immunotherapeutic treatments…

Personalized ovarian cancer vaccines developed

“This has the potential to dramatically change how we treat cancer,” says Dr. Pramod Srivastava, director of the Carole and Ray Neag Comprehensive Cancer Center at UConn Health and one of the principal investigators on the study. “This research will serve as the basis for the first ever genomics-driven personalized medicine clinical trial in immunotherapy of ovarian cancer, and will begin at UConn Health this fall,” Srivastava says. UConn bioinformatics engineer Ion Mandoiu, associate professor of computer science and engineering, collaborated as the other principal investigator for the study, which has been in development for the past four years…

Modeling tumor dormancy: What makes a tumor switch from dormant to malignant?

A new computational model developed in the laboratory of Salvatore Torquato, a Professor of Chemistry at Princeton University, may help illuminate the conditions surrounding tumor dormancy and the switch to a malignant state. Published today in PLOS ONE, the so-called cellular automaton model simulated various scenarios of tumor growth leading to tumor suppression, dormancy or proliferation. “The power of the model is that it lets people to test medically realistic scenarios,” Torquato said. In future collaborations, these scenarios could be engineered in laboratory experiments and the observed outcomes could be used to calibrate the model. …

New treatment target identified for aggressive breast cancer — ScienceDaily

The gene ErbB2, commonly called HER2, is highly expressed in about 25 percent of breast cancers. Scientists have now found the protein Erbin, thought to be an anti-tumor factor, also is highly expressed in these cancers and essential to ErbB2’s support of breast cancer. When scientists interfere with the interaction between the two in mice, it inhibits tumor development and the usual spread to the lungs, according to an international team reporting in the journal PNAS. The team documented the overexpression of both in 171 cases of mostly aggressive human breast cancer as well. …
