Effect of follow-up of MGUS on survival in patients with multiple myeloma
Patients with multiple myeloma appear to have better survival if they are found to have monoclonal gammopathy of undetermined significance first, the state that precedes MM and which is typically diagnosed as part of a medical workup for another reason, according to a study published online by JAMA Oncology.

Unregulated web marketing of genetic tests for personalized cancer care raises concerns
Websites that market personalized cancer care services often overemphasize their purported benefits and downplay their limitations, and many sites offer genetic tests whose value for guiding cancer treatment has not been shown to be clinically useful, according to a new study from Dana-Farber Cancer Institute.

Products advertised on personalized cancer care websites: True or false claims?
Although there are only a few validated genetic tests specifying individual risks for certain cancers or which can help to select genomically targeted cancer therapies, the Internet is already a major source of marketing for both legitimate tests as well as those of dubious value, according to a study published March 5 in the JNCI: Journal of the National Cancer Institute.

In vivo CRISPR-Cas9 screen sheds light on cancer metastasis and tumor evolution
For the first time, CRISPR-Cas9 gene-editing technology has been employed in a whole organism model to systematically target every gene in the genome. A team of scientists have pioneered the use of this technology to 'knock out,' or turn off, all genes across the genome systematically in an animal model of cancer, revealing genes involved in tumor evolution and metastasis and paving the way for similar studies in other cell types and diseases.

Trends of 21-gene recurrence score assay use in older patients with breast cancer
A genetic test for patients with breast cancer that helps to predict the risk of developing metastatic disease and the expected benefits of chemotherapy has been adopted quickly into clinical practice in a study of older patients and it appears to be used consistently within guidelines and equitably across geographic and racial groups, according to a study published online by JAMA Oncology.

Medical nanoparticles: Local treatment of lung cancer
Nanoparticles can function as carriers for medicines to combat lung cancer: working in a joint project, scientists from the Helmholtz Zentrum München and the Ludwig-Maximilians-Universität in Munich have developed nanocarriers that site-selectively release medicines/drugs at the tumor site in human and mouse lungs. In the journal, ACS Nano, the scientists reported that this approach led to a significant increase in the effectiveness of current cancer medicines in lung tumor tissue.

Hormone-blocking drug prevents ovarian failure and improves fertility in breast cancer patients
Breast cancer patients who are given the hormone-blocking drug goserelin during chemotherapy are less likely to experience ovarian failure and more likely to have successful pregnancies, according to results from the Prevention of Early Menopause Study to be published in the New England Journal of Medicine.

Manipulating cells' shapes could treat breast cancer
Changing the shape of breast cancer cells could make the disease more sensitive to treatments -- even driving the body's own inflammatory response against a tumor -- a new study shows. Scientists at the Institute of Cancer Research, London, showed that the shape of a tumor cell is an important factor in determining its response to inflammatory molecules, which can either promote or inhibit cancer progression.

'Stem cell' test could identify most aggressive breast cancers
Testing breast cancer cells for how closely they resemble stem cells could identify women with the most aggressive disease, a new study suggests. Researchers found that breast cancers with a similar pattern of gene activity to that of adult stem cells had a high chance of spreading to other parts of the body.

UTMB study shows testosterone being prescribed when not medically needed
A new study by the University of Texas Medical Branch found that 20 percent of men were prescribed testosterone despite having normal testosterone levels based on the Endocrine Society's guidelines. The study also found that 39 percent of new testosterone users did not have a prostate cancer screening during the year before treatment and 56 percent were not screened during the year after starting treatment.

Global studies in Health Affairs' March issue
The March issue of Health Affairs, the leading journal of health policy, contains several studies about global health. A flattening budget coupled with growing service demand drove the UK's National Health Service to seek spending cumulative efficiency savings of 17 percent over four years beginning in 2011. Identifying ineffective, overused, or inappropriate procedures was largely left to the local commissioning organizations to implement. The authors identified six high-volume but low-value procedures.
