Body position in breast cancer radiation treatment matters, experts say — ScienceDaily

Dr. Julia White of Ohio State’s Comprehensive Cancer Center — James Cancer Hospital and Solove Research Institute has helped develop a modified treatment board that allows patients to lie comfortably on their stomachs while the breast tissue falls away from the chest wall, allowing the radiation to target the cancer. Traditionally, women who undergo radiation therapy lie on their backs in the supine position. …

Obesity accelerates aging of the liver, researchers find using novel biological aging clock

Although it had long been suspected that obesity ages a person faster, it hadn’t been possible to prove the theory, said study first author Steve Horvath, a professor of human genetics at the David Geffen School of Medicine at UCLA and a professor of biostatistics at the UCLA Fielding School of Public Health. …

New cancer drug to begin trials in multiple myeloma patients

In a paper published today in the journal Cancer Cell, the researchers report how the drug, known as DTP3, kills myeloma cells in laboratory tests in human cells and mice, without causing any toxic side effects, which is the main problem with most other cancer drugs. The new drug works by stopping a key process that allows cancer cells to multiply…

New technique enables increasingly accurate PET scan to detect cancer, heart conditions

In the future, the newly developed technique will enable increasingly accurate image acquisition especially during PET scans performed to detect cancers of the chest and upper abdomen, and inflammatory diseases of the heart. PET scanning, or positron emission tomography, is a modern nuclear medicine imaging method, which allows for the detection of cancer and heart conditions. Thanks to enhanced image quality, PET images provide new and increasingly accurate data, potentially improving diagnosis reliability and treatment response monitoring. High-quality image data makes the treatment more efficient both medically and financially. …

Elevated cholesterol, triglycerides may increase risk for prostate cancer recurrence

“While laboratory studies support an important role for cholesterol in prostate cancer, population-based evidence linking cholesterol and prostate cancer is mixed,” said Emma Allott, PhD, postdoctoral associate at Duke University School of Medicine in Durham, North Carolina. “Understanding associations between obesity, cholesterol, and prostate cancer is important given that cholesterol levels are readily modifiable with diet and/or statin use, and could therefore have important, practical implications for prostate cancer prevention and treatment. “Our findings suggest that normalization, or even partial normalization, of serum lipid levels among men with dyslipidemia [abnormal lipid profile] may reduce the risk of prostate cancer recurrence,” said Allott. …

Tumor registry data find acadiana colon cancer rates among America’s highest

The study was led by Dr. Jordan Karlitz, Division of Gastroenterology at Tulane University School of Medicine who is also adjunct faculty at the LSU Health New Orleans School of Public Health, Dr. Xiao-Cheng Wu, Professor of Public Health and Director of the LSU Health New Orleans Louisiana Tumor Registry, Dr…

Pneumococcal vaccine reduces antibiotic-resistant infections in children by 62 percent

The 13-valent pneumococcal conjugate vaccine (PCV13), first available in 2010 (replacing 7-valent pneumococcal conjugate vaccine, PCV7), reduced the incidence of antibiotic-resistant invasive pneumococcal disease by 62 percent from 2009 to 2013 among children under five years old. The study is the first report of the effectiveness of PCV13 to combat antibiotic-resistant infections, a vaccination recommended for children under five years old. …

Hormone loss could be involved in colon cancer

The researchers at Thomas Jefferson University examined colon cancer samples from 281 patients and compared those tissues to nearby colon tissue that wasn’t cancerous. They found that guanylin production — measured by number of messenger RNAs for guanylin contained in each cell — decreased 100 to 1,000 times in more than 85 percent of colon cancers tested. They verified their results by also staining for the guanylin hormone production in slices of the tissue samples. …
