Cell division discovery could offer fresh insight into cancer

Scientists have explained a key part of the process of cell division, by which cells are able to keep our organs functioning properly. They discovered a set of proteins that stabilise the sequence of events in which cells duplicate their DNA and then separate into two new cells, each identical to the original. Flaws in this delicate, complex operation can lead to cancer. The findings help explain a fundamental process in all living things, in which cells must continually divide to keep the organism alive and well…

Patients with MS may be at increased risk of developing cancer

Previous research suggests that some individuals with autoimmune diseases may have an increased risk of developing cancer, but most studies have found no link between cancer and multiple sclerosis, an autoimmune disease that involves the central nervous system. To investigate further, Li-Min Sun, MD, of the Zuoying Branch of Kaohsiung Armed Forces General Hospital in Kaohsiung, Taiwan, and his colleagues assessed data from the National Health Insurance System of Taiwan, including information on 1292 patients who were diagnosed with multiple sclerosis between 1997 and 2010. Each patient was matched with four participants without the condition. "Our study was a nationwide population-based cohort study, and it revealed unexpected findings," said Dr…

Researchers develop tool to determine individual risk of prostate cancer overdiagnosis

Now, researchers at Fred Hutchinson Cancer Research Center and the University of Washington have developed a personalized tool that can predict the likelihood of prostate cancer over-diagnosis. They announced their findings this week in the online issue of the Journal of the National Cancer Institute…

Nomogram to determine individualized estimates of screen-detected prostate cancer overdiagnosis

The authors used a standard definition of overdiagnosis to refer to a cancer that would not have become symptomatic or clinically identifiable if it had not been detected by screening. Overdiagnosed cancers do not pose a risk to the patient and do not require treatment, which is associated with significant risks of impotence and incontinence. …

New study shows promise for preventing therapy resistance in tumor cells

Loss of the tumor suppressor p53 often contributes to therapy resistance in tumors. In the study, published in Cell Reports, the University of Kentucky’s Vivek Rangnekar and his colleagues activated wild type p53 in normal cells to trigger cell death in the p53-deficient cancer cells. Because p53 is intact and functional in normal cells, the researchers harnessed its potential to inhibit the growth of p53-deficient cancer cells…

Chemical imaging brings cancer tissue analysis into digital age

Mass spectrometry imaging (MSI) uses technologies that reveal how hundreds or thousands of chemical components are distributed in a tissue sample. Scientists have proposed using MSI to identify tissue types for many years, but until now, no method has been devised to apply such technology to any type of tissue. In this week’s Proceedings of the National Academy of Sciences, researchers at Imperial College London have outlined a recipe for processing MSI data and building a database of tissue types…

Cancer Statistics 2014: Death rates continue to drop

Each year, the American Cancer Society estimates the numbers of new cancer cases and deaths expected in the United States in the current year and compiles the most recent data on cancer incidence, mortality, and survival based on incidence data from the National Cancer Institute and the Centers for Disease Control and Prevention, and mortality data from the National Center for Health Statistics. The data are disseminated in two reports, Cancer Statistics, published in CA: A Cancer Journal for Clinicians, and its companion article, Cancer Facts & Figures. This year’s report estimates there will be 1,665,540 new cancer cases and 585,720 cancer deaths in the United States in 2014…

Advances in nanotechnology’s fight against cancer

A new research review co-authored by a UCLA professor provides one of the most comprehensive assessments to date of research on nanomedicine-based approaches to treating cancer and offers insight into how researchers can best position nanomedicine-based cancer treatments for FDA approval. …
