New biomarkers might help personalize metastatic colorectal cancer treatment
Metastatic colorectal cancer patients tend to live longer when they respond to the first line of chemotherapy their doctors recommend. To better predict how patients will respond to chemotherapy drugs before they begin treatment, researchers at University of California, San Diego School of Medicine conducted a proof-of-principle study with a small group of metastatic colorectal cancer patients. The results revealed two genes that could help physicians make more informed treatment decisions for patients with this disease.

New imaging technique could make brain tumor removal safer, more effective, study suggests
Brain surgery is famously difficult for good reason: when removing a tumor, for example, neurosurgeons walk a tightrope as they try to take out as much of the cancer as possible while keeping crucial brain tissue intact -- and visually distinguishing the two is often impossible. Now researchers report they have developed an imaging technology that could provide surgeons with a color-coded map of a patient's brain showing which areas are and are not cancer.

Breast-conserving therapy for early-stage cancers has increased, though access an issue
The first comprehensive national review of breast-conserving therapy (BCT) shows that over the last 13 years rates of this treatment modality for early-stage breast cancer have increased at a steady pace. However, the review also highlights important demographic factors that impact which patients have access to BCT.

Tests to gauge genetic risks for prostate cancer now are feasible
Men with an elevated, genetically inherited risk for prostate cancer could be routinely identified with a simple blood or urine test, scientists at UC San Francisco and Kaiser Permanente Northern California have concluded, potentially paving the way to better or earlier diagnosis. The study, which included 7,783 men with prostate cancer and 38,595 without the disease, is available online and will be published in an upcoming issue of the journal Cancer Discovery.

Restoring natural immunity against cancers
Scientists at the Institut Pasteur and Inserm have successfully increased the infiltration of immune cells into tumors, thus inducing the immune system to block tumor growth. In an article published in Nature Immunology, the scientists show that, in combination with existing immunotherapies, this process efficiently destroys cancer cells.

Early behavior problems may be linked to 'aging' biomarkers in preschoolers
Preschoolers with oppositional defiant behavior are more likely to have shorter telomeres, a hallmark of cellular aging, which in adults is associated with increased risk for chronic diseases and conditions like diabetes, obesity and cancer.

World spends more than $200 billion to make countries healthier
The world invested more than $200 billion to improve health in lower-income countries over the past 15 years. Global health financing increased significantly after 2000, when the United Nations established the Millennium Development Goals, which included a strong focus on health. This trend in funding has only recently started to change, according to new research by the Institute for Health Metrics and Evaluation at the University of Washington.

Researchers identify new stem cell population important in the growth of colon cancer
Researchers at Lawson Health Research Institute have identified a previously unknown, long-lived radiation-resistant stem cell population in the colon. Most importantly, they also found that these stem cells can give rise to colonic tumors and sustain their growth. The findings, which are published in the prominent journal Cell Stem Cell, will significantly change the way we study and treat colon cancer.

Study shows benefit of higher quality screening colonoscopies
An analysis that included information from more than 57,000 screening colonoscopies suggests that higher adenoma detection rates may be associated with up to 50 percent to 60 percent lower lifetime colorectal cancer incidence and death without higher overall costs, despite a higher number of colonoscopies and potential complications, according to a study in the June 16 issue of JAMA.

Protein plays key role in spread of breast cancer
For breast cancer to be fatal, the tumor has to send out metastases to other parts of the body. The cancer cells are spread via the blood vessels, and a research team at Lund University in Sweden has now proven that the protein ALK1 determines the extent of the tumor's spread in the body. The higher the levels of the protein on the surface of the blood vessels, the greater their permeability to tumor cells and therefore the greater the risk of metastases.

Drug trials in pet dogs with cancer may speed advances in human oncology
Pet dogs may be humans' best friends in a new arena of life: cancer treatment, said University of Illinois veterinary clinical medicine professor Timothy Fan. Physiological similarities between dogs and humans, and conserved genetics between some dog and human cancers, can allow pet dogs to serve as useful models for studying new cancer drugs, he said.

How the Epstein-Barr virus hides in human cells
Scientists at Helmholtz Zentrum München have now discovered how Epstein-Barr virus (EBV) conceals itself in human cells. A main culprit for its bad visibility by the immune system is the viral protein LMP2A. As published in the scientific journal PLOS Pathogens, the protein helps EBV-infected cells hide from T cells. This camouflage through the LMP2A protein may play a major role in the causation of cancer by EBV.

'Death-associated protein' promotes cancer growth in most aggressive breast cancers
Although traditionally understood to induce death in cancer cells, researchers at The University of Texas MD Anderson Cancer Center have discovered that the DAPK1 protein is actually essential for growth in breast and other cancers with mutations in the TP53 gene. This discovery indicates DAPK1 may be a promising new therapeutic target for many of the most aggressive cancers.

Microbe mobilizes 'iron shield' to block arsenic uptake in rice
University of Delaware researchers have discovered a soil microbe that mobilizes an 'iron shield' to block the uptake of toxic arsenic in rice. The UD finding gives hope that a natural, low-cost solution -- a probiotic for rice plants -- may be in sight to protect this global food source from accumulating harmful levels of one of the deadliest poisons on the planet. Rice currently is a staple in the diet of more than half the world's population.
