Contrary to treatment guidelines for high-risk bladder cancer, chemotherapy before or after surgery is not commonly used in routine clinical practice. The findings are published early online in Cancer, a peer-reviewed journal of the American Cancer Society.
Clinical trials have shown that survival is improved in patients with muscle-invasive bladder cancer who are given chemotherapy before surgery. There is less evidence about whether chemotherapy after surgery also improves survival.
To investigate the use of peri-operative chemotherapy in this disease, Christopher Booth, MD, FRCPC, of the Queen's University Cancer Research Institute in Canada, examined records pertaining to all 2944 patients who had surgery for high-risk bladder cancer in Ontario between 1994 and 2008.
Use of chemotherapy before surgery remained stable (an average of 4 percent of patients) over the study period, which is surprising given the evidence that this is a standard of care that has been demonstrated to improve survival.
The use of chemotherapy after surgery increased over time: 16 percent of patients in 1994 to 1998, 18 percent in 1999 to 2003, and 22 percent in 2004 to 2008. Study results showed that use of chemotherapy after surgery was associated with better survival.
"Results from our study demonstrate that chemotherapy given after surgery improves patient survival—probably on the same order of magnitude as chemotherapy before surgery," said Dr. Booth.
"Patients having surgery for bladder cancer should have chemotherapy, either before or after surgery. Efforts are needed to improve uptake of this treatment, which appears to be vastly underutilized."

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
