Naproxen plus acid blocking drug shows promise in preventing bladder cancer

A new study suggests there may be ways to reduce these dangerous side effects. Collaborators from the University of Michigan, the National Cancer Institute and the University of Alabama looked at naproxen, which is known to have a lower cardiovascular risk than other NSAIDs. Naproxen, like most NSAIDs and aspirin, does increase the risk for gastric ulcers or bleeding…

Geography matters: Imaging overuse seen for breast, prostate cancer in certain regions across the U.S.

Researchers from NYU Langone Medical Center and its Laura and Isaac Perlmutter Cancer Center, in a new retrospective study publishing online March 12th in JAMA Oncology, conclude that patients with low-risk prostate or breast cancer were more or less likely to receive inappropriate imaging during treatment, depending on the region of the country in which they received medical care. They examined medical records from 2004-2007 of 9,219 men with low-risk prostate cancer and 30,398 women with low-risk breast cancer, across 84 separate hospital referral regions (HRRs). …

Reaching ’80 percent by 2018′ would prevent more than 20,000 colorectal cancer deaths per year

Colorectal cancer (commonly called colon cancer) is the third leading cause of cancer death in both men and women in the United States, and the second leading cause for both sexes combined. An estimated 132,700 new cases and 49,700 deaths are expected in 2015 in the U.S. Data from the past decade show that both incidence and mortality from colon cancer are decreasing at rate of about 3% per year, largely due to the increased use of screening. Still, fewer than six in ten U.S. …

Experts warn of stem cell underuse as transplants reach one million worldwide

HSCT (also known as blood and marrow transplant) is most often used to treat diseases of the blood and several types of cancer such as multiple myeloma or leukemia. For many people with these diseases the only possibility of a cure is to have a HSCT. The procedure provides healthy cells from either the patient (autologous transplantation) or from a healthy donor (allogeneic transplantation) to replace those lost to disease or chemotherapy…

Global health experts call into question sub-Saharan cancer data

Cancer data compiled by the World Health Organisation’s (WHO) GLOBOCAN project has huge global influence and is used by Governments and international NGOs to determine health and funding priorities in sub-Saharan Africa. However, no independent evaluation of the data has ever been undertaken. For the first time, experts from Queen Mary University of London have critically evaluated all publically available information on the quality of cancer registration systems in sub-Saharan Africa. …

New tool provides maps of protein interactions for 2,800 diseases

Scientists working in the Structural Bioinformatics and Network Biology Lab have included the more than 23,000 documented genetic mutations that affect the function of 2,000 proteins in an open-access web tool, and have positioned them on the map of known interactions between human proteins. dSysMap can be accessed free of charge at http://dsysmap.irbbarcelona.org, and scientists from around the world can add their data in an anonymous manner. Developed entirely at IRB Barcelona, dSysMap (“Disease-mutations Systemic Mapping”) provides molecular details about how mutations in certain proteins alter interactions with other proteins, thus affecting the correct funcion of cellular processes. The tool has explained, for example, why mutations in a single protein can cause two distinct diseases or why mutations in different proteins can trigger the same condition. …

Growth signal can influence cancer cells’ vulnerability to drugs, study suggests

“There are several reasons why some cancer stem cells, the cells at the root of tumors and metastases, can withstand therapy meant to eradicate them. Our results point to the importance of the environment immediately surrounding the skin cancer stem cells, specifically, their exposure to the signal TGF-β,” says senior researcher Elaine Fuchs. “Ultimately, we hope this new insight could lead to better means for preventing the recurrence of these life-threatening cancers, which can occur in the skin, head, neck, esophagus, and lung, and often evade treatment.” Her team, which included first author Naoki Oshimori, a postdoctoral research associate in the lab and lab technician Daniel Oristian, focused on squamous cell carcinomas in the skin of mice. Like many normal tissue stem cells, the stem cells that produce squamous cell tumors can be classified into two types: those that divide and proliferate rapidly, and those that do so more slowly. …
