Sitting time not associated with poorer diets in US adults
Previously identified associations between TV viewing and a less healthful diet may stem from exposure to advertisements of high calorie foods and 'distracted eating' rather than the activity of sitting itself

Exercising 300 minutes per week better for reducing total fat in postmenopausal women
Postmenopausal women who exercised 300 minutes per week were better at reducing total fat and other adiposity measures, especially obese women, during a one-year clinical trial, a noteworthy finding because body fat has been associated with increased risk of postmenopausal breast cancer, according to an article published online by JAMA Oncology.

Can protein 14-3-3 sigma prevent or kill breast cancer tumors?
Every parent knows the maxim 'feed a cold, starve a fever.' In cancer, however, exactly how to feed or starve a tumor has not been easy to determine.

Increased radiation offers no survival benefit for patients with low-risk prostate cancer
Increased radiation dose is associated with higher survival rates in men with medium- and high-risk prostate cancer, but not men with low-risk prostate cancer, according to a new study from Penn Medicine published this week in JAMA Oncology.

Magnetic nanoparticles could be key to effective immunotherapy
In recent years, researchers have hotly pursued immunotherapy, a promising form of treatment that relies on harnessing and training the body's own immune system to better fight cancer and infection. Now, results of a study led by Johns Hopkins investigators suggests that a device composed of a magnetic column paired with custom-made magnetic nanoparticles may hold a key to bringing immunotherapy into widespread and successful clinical use.

Breast cancer survivors gain weight at a higher rate than their cancer-free peers
Breast cancer survivors with a family history of the disease, including those who carry BRCA1 and BRCA2 gene mutations, gained more weight over the course of four years than cancer-free women -- especially if they were treated with chemotherapy, according to a prospective study by Johns Hopkins Kimmel Cancer Center researchers.

PET adapted treatment improves outcome of patients with stages I/II Hodgkin Lymphoma
Final results of the randomized intergroup EORTC, LYSA (Lymphoma Study Association), FIL (Fondazione Italiana Linfomi) H10 trial presented at the 13th International Conference on Malignant Lymphoma in Lugano, Switzerland, on 19 June 2015 show that early FDG-PET ( 2-deoxy-2[F-18]fluoro-D-glucose positron emission tomography) adapted treatment improves the outcome of early FDG-PET-positive patients with stages I/II Hodgkin lymphoma.

A portable 'paper machine' can diagnose disease for less than $2
In the US and other industrialized nations, testing for infectious diseases and cancer often requires expensive equipment and highly trained specialists. In countries where resources are limited, performing the same diagnostics is far more challenging. To address this disparity, scientists are developing a portable, low-cost 'paper machine' for point-of-care detection of infectious diseases, genetic conditions and cancer. Their report appears in the ACS journal Analytical Chemistry.

Defective telomeres are now being linked to dozens of diseases, including many types of cancer
Studying telomeres, the structures that protect the ends of chromosomes, has become a key issue in biology. In recent years, not only has their relation to aging been confirmed; defective telomeres seem to be linked to more and more illnesses, including many types of cancer.

New classification system for brain tumors
Despite modern chemoradiation therapy it is still very difficult to give reliable prognoses for malignant gliomas. Surgical removal of the glioma is still the preferred method of treatment. Doctors at Universitätsklinikum Erlangen's Department of Neurosurgery have now developed a new procedure for analyzing radiological imaging scans which makes it possible to predict the course of a disease relatively precisely. Their findings have now been published in the journal Scientific Reports.

Anti-stress hormone may provide indication of breast cancer risk
A new study from Lund University in Sweden shows that women with low levels of an anti-stress hormone have an increased risk of getting breast cancer. The study is the first of its kind on humans and confirms previous similar observations from animal experiments.

Nanospheres shield chemo drugs, safely release high doses in response to tumor secretions
Scientists coated nanospheres of the anti-cancer drug paclitaxel with a peptide shell that shields the drug as it travels through the circulatory system. When the nanosphere reaches a cancerous tumor, enzymes that enable metastasis slice open the shell to release the drug. The targeted delivery allowed them to safely give mice 16 times the maximum tolerated dose of the clinical formulation of paclitaxel and halted the growth of cancerous tumors.

Liquid biopsy identifies mutations in colorectal cancer undetected in tissue biopsy
The CORRECT study, published ahead of print online today in The Lancet Oncology, is one of the largest trials to date comparing data provided by liquid versus tissue biopsy in metastatic colorectal cancer patients. According to the study, liquid biopsy (BEAMing technology) could become an essential tool for analyzing tumor genotypes in real time, and identifying significant mutations that occur during the course of disease and are not detected by tissue biopsy.

Cancer discovery links experimental vaccine and biological treatment
A new study at the University of Wisconsin-Madison has linked two seemingly unrelated cancer treatments that are both now being tested in clinical trials. One treatment is a vaccine that targets a structure on the outside of cancer cells, while the other is an altered enzyme that breaks apart RNA and causes the cell to commit suicide. The new understanding could help both approaches.

Noninvasive prenatal testing may also detect some maternal cancers
A study published today in the Journal of the American Medical Association shows that genetic test results, as revealed by non-invasive prenatal testing for fetal chromosome abnormalities, may detect underlying conditions in the mother, including cancer. The study reports on a case series of eight women who had abnormal noninvasive prenatal testing results. Their fetuses had normal chromosomes; retrospective genomic analysis showed the results were due to undiagnosed cancers in the mothers.

Chemotherapeutic coatings enhance tumor-frying nanoparticles
In a move akin to adding chemical weapons to a firebomb, researchers at Duke University have devised a method to deposit a thin layer of hydrogels on the surface of nanoshells designed to absorb infrared light and generate heat to destroy tumors. When heated by the nanoshells, these special hydrogels lose their water content and any drugs trapped within, creating a formidable one-two punch.
