Study examines UV nail salon lamps, risk of skin cancer
Using higher-wattage ultra violet lamps at nail salons to dry and cure polish was associated with more ultra violet-A radiation being emitted, but the brief exposure after a manicure would require multiple visits for potential DNA damage and the risk for cancer remains small.

CT in the operating room allows more precise removal of small lung cancers
A new technique that brings CT imaging into the operating room will allow surgeons to precisely demarcate and remove small sub-centimeter lung nodules, leaving as much healthy tissue as possible, according to Raphael Bueno, M.D., of Brigham and Women's Hospital in Boston. His team is presenting the results of this late-breaking research at the 94th AATS Annual Meeting in Toronto, ON, Canada on April 30, 2014.

Cutting cancer to pieces: New research on bleomycin
In a new study, lead author Basab Roy -- a researcher at Arizona State University's Biodesign Institute -- describes bleomycin's ability to cut through double-stranded DNA in cancerous cells, like a pair of scissors. Such DNA cleavage often leads to cell death in particular types of cancer cells.

Surgeons and health care settings influence type of breast cancer surgery women undergo
Breast cancer is one of the few major illnesses for which physicians may not recommend a specific treatment option. North American women are more likely to opt for precautionary breast surgery when physicians don't specifically counsel against it, according to a new study.

Coached extracurricular activities may help prevent pre-adolescent smoking and drinking
Dartmouth researchers have found that tweens (preadolescents aged 10-14) who participate in a coached team sport a few times a week or more are less likely to try smoking. Their findings on the relationship between extracurricular activity and health risk behaviors are reported in 'The relative roles of types of extracurricular activity on smoking and drinking initiation among tweens,' which was recently published in Academic Pediatrics.

Lymph node ultrasounds more accurate in obese breast cancer patients
Mayo Clinic research into whether ultrasounds to detect breast cancer in underarm lymph nodes are less effective in obese women has produced a surprising finding. Fat didn't obscure the images -- and ultrasounds showing no suspicious lymph nodes actually proved more accurate in overweight and obese patients than in women with a normal body mass index, the study found.

Breath analysis offers non-invasive method to detect early lung cancer
Researchers at the University of Louisville School of Medicine are using breath analysis to detect the presence of lung cancer. Preliminary data indicate that this promising noninvasive tool offers the sensitivity of PET scanning, and has almost twice the specificity of PET for distinguishing patients with benign lung disease from those with early stage cancer. Michael Bousamra II, M.D., Associate Professor, Department of Cardiovascular and Thoracic Surgery, is presenting the results of the study at the AATS 2014 Conference on Apr. 29, 2014.

Immunogenic mutations in tumor genomes correlate with increased patient survival
Developing immunotherapies for cancer is challenging because of significant variability among tumors and diversity in human immune types. In a study published online today in Genome Research, researchers examined the largest collection of tumor samples to date to predict patient-specific tumor mutations that may activate the patient's immune system, paving the way for more successful, personalized cancer immunotherapy.

Major lung resection safer than ever, especially at the busiest hospitals
A major new study using data from the National Cancer Data Base details the impact of annual hospital volume on 30- and 90-day mortality rates. Investigators found that major lung surgery has become progressively safer over the last few decades, although higher death rates at low-volume hospitals and an unexpected increase in mortality at 90 days compared to 30 days were observed. The study further suggests that choosing a center that performs major lung surgery regularly can have a strong impact on survival.

Poor QOL doesn't predict low survival in high-risk lung cancer patients undergoing surgery
High-risk operable lung cancer patients have poorer quality of life scores than the normal US population. However surgery can still be undertaken safely: Low global quality of life scores were not associated with lower survival, recurrence-free rate, or for higher risk for adverse events following sublobar resection, a major surgical procedure.

Brain tumor cells penetrated by tiny, degradable particles carrying genetic instructions
Working together, Johns Hopkins biomedical engineers and neurosurgeons report that they have created tiny, biodegradable 'nanoparticles' able to carry DNA to brain cancer cells in mice. The team says the results of their proof of principle experiment suggest that such particles loaded with 'death genes' might one day be given to brain cancer patients during neurosurgery to selectively kill off any remaining tumor cells without damaging normal brain tissue.

Their work provides the international community with a set of common principles by which biomarkers can be integrated into clinical trials, exchange of data can be facilitated, quality promoted, and research accelerated while simultaneously respecting local approaches and legislation.

UNC researchers discover 'master regulator' role for little-known protein in cancer cells
Researchers in the UNC School of Medicine found that the protein DAZAP1 plays a key role in the regulation of many genes through a process known as alternative splicing, and when highly expressed in cancer cell line experiments, DAZAP1 was shown to inhibit several types of cancer cells from dividing and moving. The discovery, published in the journal Nature Communications, marks the first time this little-known protein has been characterized in relation to cancer development and tumor growth.

Researchers led by Manuel Hidalgo, Vice-Director of Translational Research at CNIO, have developed a new strategy to personalized medicine in advanced cancer patients with a poor prognosis. The study has been published in the journal Clinical Cancer Research. Applying this new tool, the treatments induced clinical responses in up to 77 percent of patients, either through the stabilization of their condition or through a partial clinical response.

Well-informed patients key to accepting gene-based drug dosing
A new study out of Western University led by Dr. Michael Rieder, illustrates the need for a lot more education around pharmacogenetics -- the study of how a patient's genes can affect drug reaction and dosage. Pharmacogenetics promises to optimize patient response to therapy, but this is the first study to really investigate how patients perceive this kind of genetic testing, and whether those perceptions differ when it comes to parents and their children.

One cell type may quash tumor vaccines
Researchers suspect that many cancer vaccines fail because the immune cells that would destroy the tumor are actively suppressed. Now, researchers at Thomas Jefferson University have found that a single cell type may be to blame for the suppression, paving the way to better cancer vaccine design.
