Featured in the October edition of the Journal of Thoracic Oncology (JTO), data from The Tarceva Lung Cancer Survival Treatment (TRUST) confirms the safety and efficacy profile of erlotinib, a highly potent oral active, reversible inhibitor of epidermal growth factor receptor (EGFR) tyrosine-kinase (TK) activity in a large heterogeneous non-small cell lung cancer (NSCLC) population.
Erlotinib has been shown to significantly increase survival for patients with previously treated advanced NSCLC. Certain groups of patients with NSCLC, such as those with a particular type of cancer - adenocarcinoma , women, Asian ethnicity and non (minimal) smokers are reported to be more likely to have tumor responses to EGFR TK inhibitors (TKIs) than other groups. However, results from the TRUST study suggest that erlotinib can benefit a wide range of patients, including those who have previously been thought unlikely to benefit from this treatment.
The large, global, open-labeled, phase IV trial TRUST study included the participation of 513 centers across 51 countries, culminating safety data from more than 6,500 patients. In patients with advanced NSCLC, the progression-free survival and overall survival in this study were 3.25 months and 7.9 months, respectively, and the disease control rate (defined as the sum complete response, partial response, or stable disease) was 69 percent.
As a post marketing surveillance trial (phase IV) occurring after erlotinib received permission to be sold, the study provided an opportunity to evaluate the efficacy and safety of this medication in a broad patient population in a real-life clinical setting. Furthermore, it included patients with advanced stage IIIB/IV NSCLC who had previously failed on or were considered unsuitable to receive standard chemotherapy or radiotherapy and were ineligible for other erlotinib trials.
"The criteria used for selecting the most appropriate therapy for a patient are of particular interest to physicians," explains lead investigator Martin Reck, MD, PhD. "Tumors with EGFR mutations have been shown to be highly responsive to EGFR TKIs. Although patients whose tumors have these mutations are likely to obtain a greater magnitude of benefit from EGFR TKIs such as erlotinib, it is important to note that the absence of these mutations does not necessarily result in a lack of benefit with erlotinib therapy."

The JTO is a prized resource for medical specialists and scientists who focus on the detection, prevention, diagnosis and treatment of lung cancer. The JTO is the official monthly journal of the International Association for the Study of Lung Cancer (IASLC.org) and emphasizes a multidisciplinary approach, including original research (clinical trials and translational or basic research), reviews and opinion pieces.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.
How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...
Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.
It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
