Cancer therapy 'tumor sanctuaries' and the breeding ground of resistance
Tumors acquiring resistance is one of the major barriers to successful cancer therapy. Feng Fu, Sebastian Bonhoeffer and their collaborator Martin Nowak use mathematical models to characterize how important aspects of tumor microenvironment can impair the efficacy of targeted cancer therapies.

WSU researchers show how fatty acids can fight prostate cancer
Washington State University researchers have found a mechanism by which omega-3 fatty acids inhibit the growth and spread of prostate cancer cells. The findings, which are at odds with a 2013 study asserting that omega-3s increase the risk of prostate cancer, point the way to more effective anti-cancer drugs.

Early recall rates decline after second round of lung cancer screening
The German Lung Cancer Screening Intervention Trial shows that the early repeat scan rate for suspicious findings decreased by more than 80 percent with the second and subsequent low-dose computed tomography screens, but emphasizes the need to have an organized screening program with the baseline scan available for comparison.

Is too much artificial light at night making us sick?
Modern life, with its preponderance of inadequate exposure to natural light during the day and overexposure to artificial light at night, is not conducive to the body's natural sleep/wake cycle. UConn Health cancer epidemiologist Richard Stevens and co-author Yong Zhu from Yale University suggest such overexposure has possible ties to cancer, obesity, diabetes, and other health issues in an article published in the British journal Philosophical Transactions of the Royal Society B.

mHealth app ideal for breast cancer risk assessment, prevention
Interviewing women at a breast-imaging center in an urban safety net institution before and after they used a 'mHealth' mobile health app on a tablet, Dartmouth researchers concluded that older, diverse, and low income women found it easy to use and acceptable.

Doctors say women with aytpia or DCIS should seek second opinions after breast biopsies
While doctors almost always agree on a pathological diagnosis of invasive breast cancer, there is room for improvement when diagnosing atypia (or atypical ductal hyperplasia-ADH) and DCIS (ductal carcinoma in-situ), Dartmouth researchers have found.

The link between aspirin, NSAIDs and colon cancer prevention may hinge on genetic variations
The link between taking aspirin, non-steroidal anti-inflammatory drugs, or NSAIDS, and colorectal cancer prevention is well established, but the mechanisms behind the protective effect have not been understood. A new study, co-led by investigators at Fred Hutchinson Cancer Research Center and published March 17 in JAMA, suggests this protection differs according to variations in DNA.

Study examines diagnostic accuracy of pathologists interpreting breast biopsies
In a study in which pathologists provided diagnostic interpretation of breast biopsy slides, overall agreement between the individual pathologists' interpretations and that of an expert consensus panel was 75 percent, with the highest level of concordance for invasive breast cancer and lower levels of concordance for ductal carcinoma in situ and atypical hyperplasia, according to a study in the March 17 issue of JAMA.

Genetic background determines whether aspirin/NSAIDS will reduce colorectal cancer risk
An analysis of genetic and lifestyle data from 10 large epidemiologic studies confirmed that regular use of aspirin or NSAIDs appears to reduce the risk of colorectal cancer in most individuals but also found that a few individuals with rare genetic variants do not share this benefit.

Study suggests precision medicine for adrenal cancer
In a randomized phase 3 trial, adrenal cancer patients receiving the investigational drug linsitinib fared no better than patients receiving a placebo. But the researchers noticed a small subset of patients who had significant response and remained on the drug for an extended time.

Effect of aspirin, NSAIDs on colorectal cancer risk may differ from genetic variations
Among approximately 19,000 individuals, the use of aspirin and nonsteroidal anti-inflammatory drugs (NSAIDs) was associated with an overall lower risk of colorectal cancer, although this association differed according to certain genetic variations, according to a study in the March 17 issue of JAMA.

Macrophages may play critical role in melanoma resistance to BRAF inhibitors
Researchers at The Wistar Institute have discovered one way in which melanoma becomes resistant to a particular form of targeted therapy, and understanding this phenomenon may lead to a new melanoma target or prompt new designs of these treatments.

Microenvironment provides growth factor for metastasis
When a person has cancer that spreads to the bone and bone marrow, the tissue becomes increasingly fragile, often leading to increased bone resorption. In a surprising discovery, investigators at Children's Hospital Los Angeles found that when neuroblastoma cells metastasize to the bone, there initially occurs an increase in bone deposition, not resorption. They also determined that this process is driven by a chemical messenger called VEGFA.
