"We found that adding gefinitib to standard chemotherapy was well-tolerated by patients who had already received chemotherapy or were frail," said Dr. Argiris. "We had hoped this study would improve the survival rate of patients, but while gefinitib did postpone spread of the disease, it did not increase survival rates. The finding that the addition of gefinitib to chemotherapy can delay the growth of head and neck cancer suggests a potential beneficial effect from combination therapy."
One group of 136 patients in the placebo-controlled study received docetaxel alone, a standard treatment for head and neck cancer. A second group of 134 patients received gefinitib in addition to docetaxel. This was the first phase III randomized trial to examine the addition of gefinitib to chemotherapy for patients with head and neck cancer. Gefinitib, which also is known by the trade name Iressa, is a targeted therapy against the epidermal growth factor receptor (EGFR) with fewer side effects than traditional chemotherapies. Patients were able to take the drug orally and tolerated it well.
Dr. Argiris plans to conduct further studies to identify the subsets of patients most likely to respond to the drug and to examine patients' quality of life while taking the combination therapy.
Head and neck cancers are a group of biologically similar cancers originating from the upper aerodigestive tract, including the lip, mouth, nasal cavity, paranasal sinuses, pharynx and larynx that affect more than 45,000 individuals in the U.S. each year. Head and neck cancers are strongly associated with environmental and lifestyle risk factors, including tobacco smoking, alcohol consumption and certain strains of the sexually transmitted human papilloma virus.
Founded in 1984, the University of Pittsburgh Cancer Institute became a National Cancer Institute (NCI)-designated Comprehensive Cancer Center in six years. UPCI is the only cancer center in western Pennsylvania with this elite designation, serving the region's population of more than 6 million. Presently, UPCI receives a total of $154 million in research grants and is ranked 10th in NCI funding.

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
