A new clinical trial has shown that reducing the interval between successive doses of a commonly used chemotherapy regimen improves survival in women whose breast cancer has spread to the lymph nodes. While previous research has evaluated the use of various forms of "dose dense" chemotherapy, this is the first major controlled study to show a clear survival benefit for women with node-positive breast cancer. The study was conducted by Cancer and Leukemia Group B (CALGB) for the Breast Cancer Intergroup, a consortium of National Cancer Institute (NCI)-sponsored Cooperative Clinical Trials Groups, and is being presented today at the 25th Annual San Antonio Breast Cancer Symposium.
"This study suggests that many women with breast cancer may benefit from chemotherapy administered on a condensed schedule," said Marc L. Citron, M.D., Albert Einstein College of Medicine, who is the lead investigator of the study. "With the availability of new drugs to control one of the most serious side effects of chemotherapy administration, we can further increase the chances of survival for women with breast cancer." The dose dense regimen was made tolerable for patients because of the drug filgrastim, which helps prevent neutropenia, a serious complication of chemotherapy.
The researchers found that two dose dense regimens provided significantly higher disease-free survival rates than two regimens using conventional dosing, and that efficacy did not differ between the two dose dense regimens. Among patients on the dose dense regimens, disease-free survival was 82 percent after four years, compared to 75 percent for those who received conventional therapy. This difference corresponded to a 26 percent overall reduction in the risk of cancer recurrence. The findings confirm the predictions of a mathematical model developed in the1980s that suggested the value of increased dose density, which was the impetus for the study.

The Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP has been developing various applications for OLED microdisplays based on organic semiconductors. By integrating the capabilities of an image sensor directly into the microdisplay, eye movements can be recorded by the smart glasses and utilized for guidance and control functions, as one example. The new design will be debuted at Augmented World Expo Europe (AWE) in Berlin at Booth B25, October 18th – 19th.

With the help of artificial intelligence, chemists from the University of Basel in Switzerland have computed the characteristics of about two million crystals made up of four chemical elements. The researchers were able to identify 90 previously unknown thermodynamically stable crystals that can be regarded as new materials. They report on their findings in the scientific journal Physical Review Letters.

For the first time, Fraunhofer IKTS shows additively manufactured hardmetal tools at WorldPM 2016 in Hamburg. Mechanical, chemical as well as a high heat resistance and extreme hardness are required from tools that are used in mechanical and automotive engineering or in plastics and building materials industry. Researchers at the Fraunhofer Institute for Ceramic Technologies and Systems IKTS in Dresden managed the production of complex hardmetal tools via 3D printing in a quality that are in no way inferior to conventionally produced high-performance tools.
Fraunhofer IKTS counts decades of proven expertise in the development of hardmetals. To date, reliable cutting, drilling, pressing and stamping tools made of...
At AKL’16, the International Laser Technology Congress held in May this year, interest in the topic of process control was greater than expected. Appropriately, the event was also used to launch the Industry Working Group for Process Control in Laser Material Processing. The group provides a forum for representatives from industry and research to initiate pre-competitive projects and discuss issues such as standards, potential cost savings and feasibility.
In the age of industry 4.0, laser technology is firmly established within manufacturing. A wide variety of laser techniques – from USP ablation and additive...
Every three years, the plastics industry gathers at K, the international trade fair for plastics and rubber in Düsseldorf. The Fraunhofer Institute for Laser Technology ILT will also be attending again and presenting many innovative technologies, such as for joining plastics and metals using ultrashort pulse lasers. From October 19 to 26, you can find the Fraunhofer ILT at the joint Fraunhofer booth SC01 in Hall 7.
K is the world’s largest trade fair for the plastics and rubber industry. As in previous years, the organizers are expecting 3,000 exhibitors and more than...
