(Press-News.org) CHICAGO -- Because of the significant benefit found in combining the targeted drug ibrutinib with standard chemotherapy for relapsed chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL), an interim analysis has closed the international HELIOS phase III clinical trial.
Led by Mayo Clinic, researchers found that ibrutinib and chemotherapy (bendamustine and rituximab, known as BR) reduced the risk of death or cancer progression by almost 80 percent in patients with previously treated CLL or SLL, compared to use of BR alone.
The announcement was made at a press briefing at the 2015 meeting of the American Society of Clinical Oncology by HELIOS' senior investigator Asher Chanan-Khan, M.D., professor of medicine and chair of Hematology & Oncology, Mayo Clinic Cancer Center in Jacksonville, Florida.
"This finding represents a significant advancement in the management and treatment of this leukemia," says Dr. Chanan-Khan. "Although CLL remains incurable, this new regimen offers longer disease control and a decreased risk of relapse for our patients."
The HELIOS study -- which enrolled 578 patients from centers around the world -- was the first to compare, head-to-head, chemo immunotherapy alone to chemo immunotherapy plus a targeted drug in patients with CLL.
CLL, the most common adult leukemia in the U.S., is a B-cell cancer that is present in blood and lymph nodes. SLL is a B-cell cancer found only in lymph nodes.

EARTH: Rock stars -- Geologists on the silver screen
2015-05-29
Alexandria, VA - As this summer's blockbuster movie season gets underway, EARTH Magazine asks an important question: In movies, "are geologists portrayed as heroes or villains?" The topic of how geologists are portrayed in film has been oft-debated around a campfire, or over a frosty beverage at the end of a day of fieldwork, but now four scientists bring some serious analysis to the subject in the June issue feature, "Rock Stars - Geologists on the Silver Screen."
The authors - all geologists in the Department of Earth Sciences at the University of Gothenburg in Sweden ...
Rapid and cost-effective chromosomal phasing is possible with Droplet Digital PCR Technology
2015-05-29
Hercules, CA -- May 29, 2015 -- Researchers at Harvard Medical School and the Digital Biology Center at Bio-Rad Laboratories, Inc. have developed a rapid, scalable, and cost-effective method for chromosomal phasing that provides researchers with a new method to determine if genetic variants are linked on the same chromosome. Using Bio-Rad's Droplet Digital PCR (ddPCRTM) technology, the Drop-Phase method can rapidly determine the chromosomal phase of allelic markers hundreds of kilobases apart. This ability may provide new insights into the cause, penetrance, and severity ...
Genetic biomarker may predict cancer patients' response to immunotherapy drug
2015-05-29
In a report of a proof-of-principle study of patients with colon and other cancers for whom standard therapies failed, researchers at the Johns Hopkins Kimmel Cancer Center say that mistakes in so-called mismatch repair genes, first identified by Johns Hopkins and other scientists two decades ago, may accurately predict who will respond to certain immunotherapy drugs known as PD-1 inhibitors. Such drugs aim to disarm systems developed by cancer cells to evade detection and destruction by immune system cells.
Results of the trial with pembrolizumab, marketed as Keytruda, ...
Modeling storm surge to better protect Texas
2015-05-29
The recent floods in Texas have caused some of the worst flooding since Hurricane Ike in 2008, causing the rainiest month in the state's history.
What lessons have been learned from Ike's devastation of the Galveston and Houston area, and how have they helped in the prediction of future such storms?
Researchers at the Institute for Computational Engineering and Sciences at the University of Texas at Austin have been studying computational models and simulations of hurricanes like Ike in order to predict the consequences of such natural disasters and better prepare ...
Newer, easier to manage medications may not always be the best choice
2015-05-29
PHOENIX -- If you are over age 75, and taking an anticoagulant, the old standard may be the gold standard, Mayo Clinic researchers and collaborators have determined.
In a study released online in April in the BMJ, a team of researchers from Mayo Clinic, and other collaborators, showed that for older patients, particularly individuals greater than 75 years of age, the risk of gastrointestinal (GI) bleeding is 3 to 5 times higher when taking newer anticoagulant medications dabigatran or rivaroxaban compared to when using warfarin.
One of the most common reasons people ...
The Large Synoptic Survey Telescope: Unlocking the secrets of dark matter and dark energy
2015-05-29
At a traditional stone-laying ceremony outside La Serena, Chile on April 14th, construction officially began of the Large Synoptic Survey Telescope (LSST). This ambitious international astrophysics project is slated to start scanning the heavens in 2022. When it does, LSST should open up the "dark universe" of dark matter and dark energy--the unseen substance and force, respectively, composing 95 percent of the universe's mass and energy--as never before.
On April 2, 2015, the Director of LSST, Steven Kahn, along with astrophysicist Sarah Bridle and theoretical physicist ...
Alzheimer's culprit causes memory loss even before brain degeneration
2015-05-29
The study, published May 29 in the open access Nature Publishing Group journal Scientific Reports, reveals a direct link between the main culprit of Alzheimer's disease and memory loss.
Alzheimer's disease is characterized by the formation of amyloid plaques in the brain tissue. These amyloid plaques are made up of an insoluble protein, 'Amyloid-beta' (Abeta), which forms small structures called 'oligomers' that are important in the disease progression.
Although these proteins are known to be involved in Alzheimer's, little is understood about how they lead to memory ...
New 'designer carbon' from Stanford boosts battery performance
2015-05-29
Stanford University scientists have created a new carbon material that significantly boosts the performance of energy-storage technologies. Their results are featured on the cover of the journal ACS Central Science.
"We have developed a 'designer carbon' that is both versatile and controllable," said Zhenan Bao, the senior author of the study and a professor of chemical engineering at Stanford. "Our study shows that this material has exceptional energy-storage capacity, enabling unprecedented performance in lithium-sulfur batteries and supercapacitors."
According to ...
Experts on aging: UN Sustainable Development Goals discriminatory, ageist
2015-05-29
One of the main health targets proposed by the UN Sustainable Development Goals (SDG) is to reduce by one-third premature mortality from non-communicable diseases such as cancer, stroke and dementia. The goals for 2016-2030 define premature mortality as deaths occurring among people aged 69 years old or younger.
The proposed SDG target sends an unambiguous statement to UN member states that health provision for younger groups must be prioritised at the expense of people aged 70 or more, according to the international group of signatories of the letter published in The ...
Prosthetic hands with a sense of touch? Breakthroughs in providing 'sensory feedback' from artificial limbs
2015-05-29
May 29, 2015 - Researchers are exploring new approaches to designing prosthetic hands capable of providing "sensory feedback." Advances toward developing prostheses with a sense of touch are presented in a special topic article in the June issue of Plastic and Reconstructive Surgery®, the official medical journal of the American Society of Plastic Surgeons (ASPS).
Emerging sensory feedback techniques will provide some sensation and enable more natural, intuitive use of hand prostheses, according to the review by ASPS Member Surgeon Paul S. Cederna, MD, of University ...
