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: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...

Im Focus: Using graphene to create quantum bits

In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits -- or qubits -- that are stable, meaning they are not much affected by changes in their environment. This normally needs highly nonlinear non-dissipative elements capable of functioning at very low temperatures.

In pursuit of this goal, researchers at EPFL's Laboratory of Photonics and Quantum Measurements LPQM (STI/SB), have investigated a nonlinear graphene-based...
