Chemotherapy before or after surgery for high-risk bladder cancer improves survival, but is not routinely administered

14.04.2014

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."

Im Focus: Basel Physicists Develop Efficient Method of Signal Transmission from Nanocomponents

Physicists have developed an innovative method that could enable the efficient use of nanocomponents in electronic circuits. To achieve this, they have developed a layout in which a nanocomponent is connected to two electrical conductors, which uncouple the electrical signal in a highly efficient manner. The scientists at the Department of Physics and the Swiss Nanoscience Institute at the University of Basel have published their results in the scientific journal “Nature Communications” together with their colleagues from ETH Zurich.

Electronic components are becoming smaller and smaller. Components measuring just a few nanometers – the size of around ten atoms – are already being produced...

Im Focus: Into the ice – RV Polarstern opens the arctic season by setting course for Spitsbergen

On Tuesday, 19 May 2015 the research icebreaker Polarstern will leave its home port in Bremerhaven, setting a course for the Arctic. Led by Dr Ilka Peeken from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) a team of 53 researchers from 11 countries will investigate the effects of climate change in the Arctic, from the surface ice floes down to the seafloor.

RV Polarstern will enter the sea-ice zone north of Spitsbergen. Covering two shallow regions on their way to deeper waters, the scientists on board will focus...

Im Focus: Gel filled with nanosponges cleans up MRSA infections

Nanoengineers at the University of California, San Diego developed a gel filled with toxin-absorbing nanosponges that could lead to an effective treatment for skin and wound infections caused by MRSA (methicillin-resistant Staphylococcus aureus), an antibiotic-resistant bacteria. This "nanosponge-hydrogel" minimized the growth of skin lesions on mice infected with MRSA - without the use of antibiotics. The researchers recently published their findings online in Advanced Materials.

To make the nanosponge-hydrogel, the team mixed nanosponges, which are nanoparticles that absorb dangerous toxins produced by MRSA, E. coli and other...
