New evidence about the breast cancer drug anastrozole (Arimidex) shows that the incidence of a major side-effect – bone fractures – appears to stabilise after reaching a peak at two years of treatment, easing some of the concerns about the drug.
This finding is the latest to come from evidence provided by the worlds largest international study of breast cancer treatment, the ATAC trial, which compared the aromatase inhibitor anastrozole with breast cancers current gold standard hormone treatment tamoxifen, and with both treatments combined.
The trial, involving more than 9,000 post menopausal women in 21 countries, last year revealed that over a median follow-up of patients of 33 months, anastrozole enhanced disease-free survival by 19% and cut the incidence of new tumours in the opposite breast by 58% compared to tamoxifen. This represented an absolute difference of 1.8% in favour of anastrozole. An update at 47 months median follow up showed that the gap had widened to an absolute difference of 2.6% in favour of the newer drug. Overall survival comparisons from the trial should be available next year.

At the ILA Berlin, hall 4, booth 202, Fraunhofer FHR will present two radar sensors for navigation support of drones. The sensors are valuable components in the implementation of autonomous flying drones: they function as obstacle detectors to prevent collisions. Radar sensors also operate reliably in restricted visibility, e.g. in foggy or dusty conditions. Due to their ability to measure distances with high precision, the radar sensors can also be used as altimeters when other sources of information such as barometers or GPS are not available or cannot operate optimally.
Drones play an increasingly important role in the area of logistics and services. Well-known logistic companies place great hope in these compact, aerial...
