The 2nd ESTRO ForumMathematical models out-perform doctors in predicting cancer patients' responses to treatment Mathematical prediction models are better than doctors at predicting the outcomes and responses of lung cancer patients to treatment, according to new research presented on Saturday at the 2nd Forum of the European Society for Radiotherapy and Oncology. The presenter will say that she considers it unethical for treatment decisions to be based solely on doctors' opinions, when these models perform so much better. Contact: Emma Mason

2013 ARRS Annual MeetingTomosynthesis increases breast cancer detection rate Two-dimensional plus 3-D breast imaging increases cancer detection rates by 11 percent, and could be particularly useful in detecting cancer in women with dense breasts, a new study suggests. Contact: Samantha Schmidt

2013 ARRS Annual MeetingChemical shift MRI helps differentiate renal cell tumors more likely to metastasize Adding "chemical shift" techniques to MRI can help differentiate clear cell renal cell carcinoma from other types of renal cell cancer, a new study shows. That differentiation can help physicians better determine treatment for these patients. Contact: Samantha Schmidt

2013 ARRS Annual Meeting2 views are better than 1 in 3-D breast screening One-view 3-D breast screening (tomosynthesis) means less radiation dose and about five seconds less compression, but a study from Yale University, New Haven, Conn., found that obtaining both views is necessary to help ensure that a cancer won't be missed.

 PLOS ONEIdentified as responsible for breast and ovarian hereditary cancer 3 mutations at BRCA1 gene Researchers of the hereditary cancer research group at the Bellvitge Biomedical Research Institute and the Catalan Institute of Oncology conducted a functional and structural study of seven missense variants of the BRCA1 gene concluding that three of these variants are pathogenic, linked to the risk of suffering breast or ovarian cancer. The study has been published at PLoS One.

2013 ARRS Annual MeetingScreening breast ultrasound detects cancers missed on mammography in women with dense breasts Screening breast ultrasound performed after mammography on women with greater than 50 percent breast density detects an additional 3.4 cancers or high risk lesions per one thousand woman screened, a detection rate just under that of screening mammography alone for women with less dense breasts, a new study shows. Screening mammography detects 4-5 cancers per thousand women screened. Contact: Samantha Schmidt

American Journal of Human GeneticsScientists find ethnicity linked to antibodies Cracking the DNA code for a complex region of the human genome has helped 14 North American scientists, including five at Simon Fraser University, chart new territory in immunity research. They have discovered that a good number of our antibody genes and, potentially, what they fight off actually vary from person to person. After completely sequencing the immensely repetitive DNA in the human genome's immunoglobulin heavy-chain locus, they have also found ethnicity influences immunity. Contact: Carol Thorbes

Breast Cancer Research and TreatmentCold winters freezing out breast cancer treatment For women diagnosed with estrogen receptor positive breast cancer, tamoxifen is an essential drug used in treatment and prevention. Currently, tamoxifen is used in a one-size-fits-all approach where the same dose is prescribed for every patient. New research at Lawson Health Research Institute has found that in addition to patient-specific genetic factors, lack of exposure to vitamin D during the long winter months affects the body's ability to metabolize the drug.

Infection and ImmunityHigh-salt diet and ulcer bug combine to increase risk of cancer Numerous epidemiologic studies have shown that a diet high in salt is associated with an increased risk of gastric cancer. Now Timothy L. Cover and colleagues of Vanderbilt University show that high dietary salt combined with infection by the ulcer-causing bacterium Helicobacter pylori greatly increases the risk of cancer.

Cancer Epidemiology, Biomarkers & PreventionSmoking from hookah not a harmless alternative to cigarettes Smoking tobacco through a hookah is a pastime gaining popularity among the college crowd, but many of them mistakenly believe that using the fragrant water pipe is less harmful than smoking cigarettes.

American Journal of Health PromotionSome minorities believe they are less likely to get cancer compared to whites, Moffitt study shows Researchers at Moffitt Cancer Center and colleagues analyzed national data to investigate the differences in cancer prevention beliefs by race and ethnicity. They found that minorities, including blacks, Asians and Hispanics, have differing beliefs about cancer prevention and feel they are less likely to get cancer than did whites. The researchers concluded that more culturally relevant information about cancer prevention and risk needs to reach minority populations. Contact: Kim Polacek

Science Translational MedicineDREAM and Sage Bionetworks tap the wisdom of the crowd to impact breast cancer prognosis Two new reports issuing in Science Translational Medicine today showcase the potential of teams of scientists working together to solve increasingly complex medical problems. The results demonstrate that better predictors of breast cancer progression than those currently available can be rapidly evolved by running open Big Data Challenges such as The Sage Bionetworks/DREAM Breast Cancer Prognosis Challenge.

Proceedings of the National Academy of SciencesVirus-like particles provide vital clues about brain tumors Exosomes are small, virus-like particles that can transport genetic material and signal substances between cells. Researchers at Lund University, Sweden, have made new findings about exosomes released from aggressive brain tumors, gliomas. These exosomes are shown to have an important function in brain tumor development, and could be utilized as biomarkers to assess tumor aggressiveness through a blood test. Contact: Mattias Belting

NatureFamily ties: Relationship between human and zebrafish genomes Researchers have developed a high-quality zebrafish genome to compare with the human reference genome and found that 84 percent of genes known to be associated with human disease have a zebrafish counterpart. This highlights the importance of zebrafish as a model organism for human disease research. Contact: Aileen Sheehy

Scientific ReportsRecipe for large numbers of stem cells requires only one ingredient, says NIH/Pitt team Stem cells and tissue-specific cells can be grown in abundance from mature mammalian cells simply by blocking a certain membrane protein, according to scientists at the University of Pittsburgh School of Medicine and the National Institutes of Health. Their experiments, reported today in Scientific Reports, also show that the process doesn't require other kinds of cells or agents to artificially support cell growth and doesn't activate cancer genes.

eLifeReproductive tract secretions elicit ovulation Eggs take a long time to produce in the ovary, and thus are one of a body's precious resources. It has been theorized that the body has mechanisms to help the ovary ensure that ovulated eggs enter the reproductive tract at the right time in order to maximize the chance of successful fertilization. New research from Carnegie's Allan Spradling and Jianjun Sun has shed light on how successful ovulation and fertilization are brought about by studying these processes in fruit flies.

Cancer ResearchNew drug combination therapy developed to treat leukemia A new, pre-clinical study by researchers at Virginia Commonwealth University Massey Cancer Center suggests that a novel drug combination could lead to profound leukemia cell death by disrupting the function of two major pro-survival proteins. The effectiveness of the therapy lies in its ability to target a pro-survival cell signaling pathway known as PI3K/AKT/mTOR, upon which the leukemia cells have become dependent.

Journal of Experimental MedicineMolecule treats leukemia by preventing cancer cell repair, Jackson Laboratory scientists report Researchers at The Jackson Laboratory have identified a molecule that prevents repair of some cancer cells, providing a potential new "genetic chemotherapy" approach to cancer treatment that could significantly reduce side effects and the development of treatment resistance compared with traditional chemotherapy.
