But researchers at UT Southwestern Medical Center and Karolinska Institutet in Stockholm, Sweden, found that endogenous retroviruses (ERV) also play a critical role in the body’s immune defense against common bacterial and viral pathogens. “Most scientists have become used to the view that retroviruses are generally harmful,” said Nobel Laureate Dr. …
The study suggests that doctors and patients may find it difficult to withhold treatment previously considered standard of care, even in the setting of high quality data demonstrating that the advantages are small. “The onus is on physicians to critically analyze data to shape our treatment recommendations for patients, weighing the potential toxicities of treatment against clinical benefit,” said Rachel Blitzblau, M.D., Ph.D., the Butler Harris Assistant Professor of Radiation Oncology at Duke University Medical Center. Blitzblau was the senior author of a study published online Dec. 8, 2014, in the journal Cancer. …
Now research in an animal model finds that a novel combination therapy, which couples low-dose chemotherapy with an antiangiogenic treatment, resulted in better survival rates compared with standard therapy. Led by investigators at Beth Israel Deaconess Medical Center (BIDMC) and the University of Guelph, the findings show that the agent, 3TSR, not only led to tumor regression, but also improved tumor blood flow and enabled more efficient delivery of much smaller and less toxic doses of chemotherapy. The study currently appears online in The Journal of the Federation of American Societies for Experimental Biology (FASEB) and will be published in the February 2015 print issue. …
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. …
Wilms tumor is the most common childhood genitourinary tract cancer and the third most common solid tumor of childhood. “While most children with Wilms tumor are thankfully cured, those with more aggressive tumors do poorly, and we are increasingly concerned about the long-term adverse side effects of chemotherapy in Wilms tumor patients. …
That’s hardly an earth-shattering observation, but the fact is that, aside from the most obvious physical differences between the sexes, medicine has traditionally treated women as if they were merely smaller men. “When we look closely, we tend to find differences” between men and women, said Sarah L. Berga, M.D., professor and chair of obstetrics and gynecology and vice president for women’s health services at Wake Forest Baptist Medical Center. “But for most of the past, we never looked.” That started to change in the late 1980s, when physicians and researchers recognized that women’s health encompassed more than those conditions unique to females; that women’s experiences with gender-common conditions and the treatments for them often differed significantly from those of men…
“Although the effects of the drug were modest, we now know that we can influence the course of the disease, and we expect to build on this success with other drugs, including some already in development,” said senior author, Gary K. Schwartz, MD, professor of medicine and chief of hematology/oncology at NewYork-Presbyterian/Columbia University Medical Center and associate director of its Herbert Irving Comprehensive Cancer Center. (At the time of the trial, Dr. Schwartz was chief of the melanoma and sarcoma service at Memorial Sloan Kettering Cancer Center in New York.) Uveal melanoma is a cancer of the iris, ciliary body, or choroid — structures in the eye collectively known as the uvea…
