Wireless sensor transmits tumor pressure

Contents under Pressure Tumors, like healthy tissues, need oxygen and nutrients to survive. In order to accommodate the demands of a growing tumor, blood vessels from surrounding tissue begin to grow into the tumor. Yet, unlike normal tissue, these newly formed blood vessels are disorganized, twisty, and leaky. It’s thought that the high pressure observed in tumors is a result of these abnormal blood vessels, which leak fluid and proteins into the area between tumor cells, known as the interstitial space…

Study adds to cancer-fighting promise of combined immunotherapy-radiation treatment

The study, led by Johns Hopkins Kimmel Cancer Center researchers, shows how in principle, radiation may specifically activate immune system cells responsible for attacking cancer cells, leading immune cells to “remember” how to fight cancer long after the cancer is gone. Andrew Sharabi, M.D., Ph.D., a resident in the Department of Radiation Oncology and Molecular Radiation Science at Johns Hopkins, is expected to present details of the study at the 2014 annual meeting of the American Society of Radiation Oncology (ASTRO) in San Francisco Sept. 15…

Professional recommendations against routine prostate cancer screening have little effect — ScienceDaily

The study, published as a research letter online in JAMA Internal Medicine, focused on the use of PSA — prostate-specific antigen — to test for prostate cancer. “We found that the effect of the guidelines recommending against the routine screening of elderly men in particular has been minimal at best,” says Jesse Sammon, D.O., a researcher at Henry Ford’s Vattikuti Urology Institute and lead author of the study. The researchers found an estimated 17 million men age 50 or older without a history of prostate cancer or prostate problems who reported undergoing PSA screening…

Many throat cancer patients can skip neck surgery

“For patients that achieve a complete response, neck surgery is probably unnecessary,” says Thomas J. Galloway, MD, Attending Physician and Director of Clinical Research at Fox Chase and lead author on the study. After radiation and chemotherapy to remove tumors from the tonsils or back of the tongue, many head and neck cancer patients still have persistent lumps in their neck, albeit perhaps smaller than when they were first diagnosed. “The question is: Do we need to remove those lumps, as well, or can we just let them dissolve on their own?” asks Dr. …

Abnormal properties of cancer protein revealed in fly eyes

In a paper featured on the cover of the current issue of the Journal of Biological Chemistry, Michigan State University researchers provide the first detailed examination of a set of mutations similar to those present in the human cancer gene, said Irina Pushel, MSU undergraduate and co-author. “By systematically evaluating mutations of increasing severity, we now have a model to better predict how we think the protein will react with each mutation,” said Pushel, who co-authored the paper with Liang Zhang, lead author and MSU graduate student, and Bill Henry and David Arnosti, MSU molecular biologists. …
