One of the major problems with prostate cancer is that, with today's prognosis markers, some 70-80 percent of patients wind up in a group where very little can be said about their prognosis.
Unfortunately, today no methods to are good enough determine which patients truly need treatment and which ones can get along fine without the difficult treatment. This in turn means that certain patients are over-treated with therapies that can lead to serious side effects and that other patients who really need intensive treatment do not get it or get it too late.
In a study recently published in the scientific journal Clinical Cancer Research, Hammarsten studied tissue biopsies from prostate tumors in 259 patients and found a new prognosis marker for prostate cancer. It is the active form of the protein EFGR (Epidermal Growth Factor Receptor) that was shown to provide information about the aggressiveness of the tumor, both when it is measured in the tumor or in the healthy tissue surrounding the tumor.
EGFR belongs to the same family as the prognosis marker HER2, which is used today for breast cancer to determine the aggressiveness of a tumor that is to be treated with inhibitors of HER2, that is, the drug Herceptin. In a similar way, it may be possible in the future to use the active form of EGFR to select patients with a poor prognosis and are suitable for treatment with inhibitors of EGFR. In order to use EGFR as a prognosis marker clinically in the future, further studies will need to target its expressions in other and larger material in prostate tumors.
Prostate cancer is the most common cancer form among men in Sweden. Every year some 10,000 men are diagnosed with prostate cancer. Some 2,500 of them will die of their disease. In other words, some patients have an aggressive fatal disease, whereas others have a slowly growing tumor that will not cause any major problems.

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.
Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...
The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.
Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.
An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.
Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
