Comprehensive breast center improves quality of care for breast reconstruction — ScienceDaily

Centralized breast cancer care at CBCs can lead to more timely breast reconstruction for women undergoing breast cancer surgery, suggests the study by ASPS Member Surgeon Albert H. Chao, MD, and colleagues of The Ohio State University, Columbus. They write, “Access to breast reconstruction at our institution improved significantly after our CBC opened, with significant increases in internal referral rates and immediate reconstruction rates.” Transition to CBC Improves Processes of Care The researchers assessed “process of care” outcomes related to breast reconstruction before and after their hospital transitioned to a CBC approach. Comprehensive breast centers seek to improve patient care and outcomes by assembling a group of highly specialized practitioners — oncologists, plastic and reconstructive surgeons, and other professionals — to provide coordinated breast cancer care…

Clear new evidence for mind-body connection demonstrated in study

A group working out of Alberta Health Services’ Tom Baker Cancer Centre and the University of Calgary Department of Oncology has demonstrated that telomeres — protein complexes at the end of chromosomes — maintain their length in breast cancer survivors who practise meditation or are involved in support groups, while they shorten in a comparison group without any intervention. Although the disease-regulating properties of telomeres aren’t fully understood, shortened telomeres are associated with several disease states, as well as cell aging, while longer telomeres are thought to be protective against disease…

From HIV to cancer, IL-37 regulates immune system

“Knowing this mechanism that underlies IL-37’s effect on the immune system now allows us to study IL-37 function and perhaps dysfunction in a wide range of diseases,” says Mayumi Fujita, MD, PhD, investigator at the University of Colorado Cancer Center, associate professor in the CU School of Medicine Department of Dermatology, and the paper’s senior author. For example, knowing that IL-37 helps to create overall immune system sensitivity could allow researchers to manipulate IL-37 levels to sensitize the immune system to recognize and target tumor tissue, or desensitize the immune system in auto-immune conditions like rheumatoid arthritis in which the immune system acts over-aggressively toward healthy tissue. …

Half of smokers using Liverpool Stop Smoking Services used e-cigs

The data — presented at the National Cancer Research Institute (NCRI) Cancer Conference in Liverpool — also highlights that smokers are more likely to try e-cigarettes if they feel more confident that the products are safer than tobacco smoking. Researchers from the University of Liverpool quizzed more than 320 smokers from the Roy Castle FagEnds study to understand the number of people who used e-cigarettes and what smokers thought about the products. Smokers appear undecided towards e-cigarettes, possibly due to the widely documented uncertainties about safety and effectiveness in helping smokers to successfully break their addiction. Some also viewed using e-cigarettes as an extension of smoking and perceived them as an inferior tool for helping to quit smoking…

Step towards blood test for many cancer types

This is the first time that cancer-specific blood markers have been comprehensively reviewed and identified for further clinical development. This study, by the UK Early Cancer Detection Consortium, funded by Cancer Research UK, has analysed 19,000 scientific papers and found more than 800 biomarkers. The aim of this research is to develop a screening test from a single blood sample for multiple cancer types. All cancers produce markers in the blood, so it could be feasible to develop a general screening test for many different forms of the disease. …

Clock gene dysregulation may explain overactive bladder — ScienceDaily

“We hope our study will stimulate further progress in understanding circadian control of body physiology and aging-related dysfunction and ultimately lead to new strategies of treatment by targeting the circadian regulatory process, including non-drug treatment approaches,” said Changhao Wu, M.D., Ph.D., a researcher involved in the work from the Department of Biochemistry and Physiology at the University of Surrey in the United Kingdom. To make this discovery, scientists used genetically modified mice in which a special wavelength of light was emitted when the clock proteins were produced in isolated bladder tissue. This light reported real-time clock expression and acted directly as a measure of peripheral clock expression…

‘Treasure in saliva’ may reveal deadly diseases early enough to treat them

The study, the most comprehensive analysis ever conducted of RNA molecules in human saliva, reveals that saliva contains many of the same disease-revealing molecules that are contained in blood. It was published online today by the peer-reviewed journal Clinical Chemistry and will be published in the journal’s January 2015 special print issue, “Molecular Diagnostics: A Revolution in Progress.” “If we can define the boundaries of molecular targets in saliva, then we can ask what the constituents in saliva are that can mark someone who has pre-diabetes or the early stages of oral cancer or pancreatic cancer — and we can utilize this knowledge for personalized medicine,” said Dr…

Genetic architecture of kidney cancer uncovered by research

The research, by an international team led by scientists from the McGill University and Genome Quebec Innovation Centre in Montreal, underscores the importance of investigating possible sources of exposure to aristolochic acid. The compound, found in plants of the Aristolochia genus, also has been suspected of causing a kidney disease known as Balkan endemic nephropathy, affecting people along the tributaries of the Danube River in Croatia, Bosnia and Herzegovina, Serbia, Bulgaria and Romania. Aristolochia clematitis, or European birthwort, is a common plant throughout the Balkans. Results of the study, which focused on the most common form of kidney cancer — clear-cell renal cell carcinoma — are reported in Nature Communications…

Prostate cancer medications linked with increased risk of heart-related deaths in men with cardiovascular problems

Androgen deprivation therapy (ADT), which reduces levels of male hormones in the body to prevent them from stimulating cancer cells, is a mainstay of treatment for prostate cancer. Despite its anticancer effects, ADT has been associated with heart problems, including increased risk of diabetes, coronary heart disease, heart attacks, and sudden cardiac death. To investigate this potential link thoroughly, Paul Nguyen, MD, of the Dana-Farber/Brigham and Women’s Cancer Center in Boston, along with David Ziehr of Harvard Medical School and their colleagues, analyzed information on 5,077 men with prostate cancer who were treated between 1997 and 2006. …
