Low breast density in mammography worsens breast cancer prognosis
Very low mammographic breast density worsens the prognosis of breast cancer, according to a recent study from the University of Eastern Finland. Disease free survivals as well as overall life expectancies were significantly shorter in women with very low-density breasts in comparison to women with high-density breast tissue. The lower the breast tissue density, the less fibroglandular tissue there is compared to fat tissue.

Geography matters: Imaging overuse seen in certain US regions
Researchers from NYU Langone Medical Center conclude that patients with low-risk prostate or breast cancer were more likely to receive inappropriate imaging during treatment, based on the region of the country in which they received medical care.

Germline TP53 mutations in patients with early-onset colorectal cancer
In a group of patients diagnosed with colorectal cancer at 40 or younger, 1.3 percent of the patients carried germline TP53 gene mutations, although none of the patients met the clinical criteria for an inherited cancer syndrome associated with higher lifetime risks of multiple cancers, according to a study published online by JAMA Oncology.

Study examines association of inappropriate prostate, breast cancer imaging
An association of high rates of inappropriate imaging for prostate cancer and breast cancer identified in a study of Medicare beneficiaries suggests that, at the regional level, regional culture and infrastructure could contribute to inappropriate imaging, something policymakers should want to consider as they seek to improve the quality of care and reduce health care spending, according to a study published online by JAMA Oncology.

New genome-editing technology to help treat blood cancers
Melbourne researchers have developed a new genome editing technology that can target and kill blood cancer cells with high accuracy. Using the technology, researchers from the Walter and Eliza Hall Institute were able to kill human lymphoma cells by locating and deleting an essential gene for cancer cell survival.

Stem cells lurking in tumors can resist treatment
Scientists are eager to make use of stem cells' extraordinary power to transform into nearly any kind of cell, but that ability also is cause for concern in cancer treatment. For the first-time, scientists at Washington University School of Medicine in St. Louis have isolated treatment-resistant cancer stem cells from low-grade tumors.

Molecules in prostate tumors might predict whether RT can help prevent recurrence
A new study has identified a group of molecules in prostate-cancer cells that doctors might one day use to distinguish which patients should be treated with radiation therapy if rising PSA levels indicate their cancer has recurred after surgical removal of the prostate.

'Quantum jitters' could form basis of evolution, cancer
Duke researchers have discovered 'quantum jitters,' in which DNA's four basic building blocks temporarily change shapes, fooling DNA-replication machinery into making a copying mistake. This shape-shifting is exceedingly rare and only flickers into existence for a thousandth of a second. But these jitters occur with the same frequency as DNA copying mistakes, a hint that this might be the basis of the genetic mutations that drive evolution and diseases like cancer.

Honey, I shrunk the ants: How environment controls size
Until now scientists have believed that the variations in traits such as our height, skin colour, tendency to gain weight or not, intelligence, tendency to develop certain diseases, etc., all of them traits that exist along a continuum, were a result of both genetic and environmental factors. But they didn't know how exactly these things worked together. By studying ants, McGill researchers have identified a key mechanism by which epigenetic factors influence the expression of all of these traits.

Urging HPV vaccine for boys could protect more people at same price
Whether vaccinating US boys against HPV in addition to girls is worth the cost has been hotly debated. But with HPV-related cancers in men on the rise, and coverage in girls stagnating below the levels needed to ensure that most people are protected, research suggests that devoting a portion of HPV funding to boys -- rather than merely attempting to improve female coverage -- may protect more people for the same price.

Deadly to cancer cells only
Parvoviruses can destroy cancer cells and are currently being tested in a preliminary clinical trial to treat malignant brain cancer. For their replication, the viruses need a particular enzyme in the cell. Scientists from the German Cancer Research Center have now discovered that in healthy human cells, parvoviruses are unable to activate this enzyme. In many cases of malignant brain cancer, however, the enzyme is permanently active. As a result, this enables the viruses to replicate and to destroy the cancer cells.

Scientists show proteins critical in day-night cycles also protect cells from mutations
New research from The Scripps Research Institute shows that two proteins critical for maintaining healthy day-night cycles also protect against mutations that could lead to cancer. The new study shows that the two proteins have an unexpected role in DNA repair, possibly protecting cells from cancer-causing mutations triggered by UV radiation.

Regenstrief study finds natural language processing accurately tracks colonoscopy quality
An accurate system for tracking the quality of colonoscopies and determining the appropriate intervals between these procedures could contribute to both better health outcomes and lower costs. Clinician-researchers from the Regenstrief Institute have created and tested such a system in the nation's first multiple institution colonoscopy quality measurement study utilizing natural language processing and report that it is as accurate but less expensive than human review.

Researchers map 'genomic landscape' of childhood adrenocortical tumors for the first time
In an advance that could lead to better identification of malignant pediatric adrenocortical tumors, and ultimately to better treatment, researchers have mapped the 'genomic landscape' of these rare childhood tumors. Their genomic mapping has revealed unprecedented details, not only of the aberrant genetic and chromosomal changes that drive the cancer, but the sequence of those changes that trigger it.

Viagra in combination with new drugs can have anti-cancer, antibacterial, and therapeutic effects
Chaperone proteins play an important role in protein folding in human cells and in bacteria and are promising new targets for drugs to treat cancer and Alzheimer's disease and for novel antiviral drugs and antibiotics. How existing drugs such as Viagra or Cialis and a derivative of the drug Celebrex, for example, can reduce the activity of a specific chaperone protein, with the potential for anti-tumor and anti-Alzheimer's disease effects, is described in a Review article in DNA and Cell Biology.
