Factors that link HPV and oesophageal cancer
7/26/2013
The human papillomavirus (HPV) triples the risk of people developing yet another cancer, oesophageal squamous cell carcinoma (OSCC), according to research led by University of New South Wales (UNSW) academics. In addition to causing cervical, anal and genital cancers, HPV has more recently been found to cause some head and neck cancers...
Targeting HER1 receptor for peptide cancer vaccine, therapeutic agents
7/26/2013
Small proteins called peptides that consist of 10 to 50 amino acids are being studied as cancer vaccines and as possibly safer, more effective and less costly alternatives to the monoclonal-antibody-based drugs and small-molecule inhibitors now used to treat many malignancies. Researchers at The Ohio State University Comprehensive Cancer Center - Arthur G. James Cancer Hospital and Richard J...
The worst bone tumors not found to be driven by pathways activated in most K9 bone tumors
7/26/2013
Many cancers show inappropriate activation of a cell signaling pathway called NOTCH. In the developing body, NOTCH tells brain cells to grow and proliferate. It should be quiet in the adult body, but cancers restart NOTCH to drive their own growth, far and beyond the rate of healthy tissues...
Combining oxygen with radiation therapy decelerates many cancer tumors
7/26/2013
A multidisciplinary team at UT Southwestern Medical Center has found that measuring the oxygenation of tumors can be a valuable tool in guiding radiation therapy, opening the door for personalized therapies that keep tumors in check with oxygen enhancement. In research examining tissue oxygenation levels and predicting radiation response, UT Southwestern scientists led by Dr...
Mammography recall rates higher from hospitals
7/26/2013
The rate at which women get called back for additional imaging after screening mammography may be higher at hospitals than at community office practices, mostly due to differences among the patients, according to a new study published online in the journal Radiology. The findings highlight the limitations of recall rates as a quality measure for breast cancer screening, the researchers said...
More people beating skin cancer - UK report
7/25/2013
Cancer Research UK says more and more people are surviving malignant melanoma, the most dangerous form of skin cancer. Their latest statistics, published online this week, reveal that more than 8 in 10 people diagnosed with malignant melanoma will now survive the disease. Forty years ago, the survival rate was only around 5 in 10...
Key role in HPV prevention played by vaccination of boys
7/25/2013
Improving vaccination rates against the human papillomavirus (HPV) in boys aged 11 to 21 is key to protecting both men and women, says new research from University of Toronto Professor Peter A. Newman from the Factor-Inwentash Faculty of Social Work. HPV has been linked to anal, penile and certain types of throat cancers in men...
Campaign results in plummeting rates of unnecessary medical tests in sweden
7/25/2013
The rate of inappropriate cancer scans for low-risk prostate cancer patients in Sweden plummeted in the decade following a joint campaign to curtail such tests by Swedish County Councils and the National Prostate Cancer Register (NPCR) of Sweden, a professional association of Swedish urologists...
New approach for studying deadly brain cancer
7/25/2013
Human glioblastoma multiforme, one of the most common, aggressive and deadly forms of brain cancer, is notoriously difficult to study. Scientists have traditionally studied cancer cells in petri dishes, which have none of the properties of the brain tissues in which these cancers grow, or in expensive animal models...
New strategy for fiber tracking in human brain
7/25/2013
Diffusion tensor imaging fiber tracking with reliable tracking orientation and flexible step size can show white matter fiber bundles in the healthy corpus callosum. Researchers used two sets of human data to assess the performance of this method; one was from a healthy volunteer and the other from a patient with low-grade glioma...
