Mayo Clinic study finds aggressive surgery is best for children with brain tumors

23.11.2010
Where complete tumor removal not possible, radiation therapy yields similar results

A new Mayo Clinic study (http://newsblog.mayoclinic.org/2008/12/03/brain-tumors-best-treatments-for-long-term-survival/) found that children with low-grade brain tumors (gliomas) (http://www.mayoclinic.org/brain-tumors/) who undergo aggressive surgery to completely remove the tumor have an increased chance of overall survival.

If complete removal is not possible, adding radiation therapy to a less complete surgery provides patients with the same outcomes as a complete removal. This study was presented at the Society for NeuroOncology Annual Scientific Meeting and Education Day in Montreal on Nov. 21.

"This study further reinforces Mayo Clinic's practice of aggressive surgical resection," says Nadia Laack, M.D., a Mayo Clinic radiation oncologist and the study's lead author. "We found that when compared to previous studies, more children are now able to have complete removals, most likely due to the fact that we have better neurosurgical techniques and better imaging techniques that help guide the surgeons."

As part of an ongoing study, Dr. Laack and a team of Mayo Clinic researchers identified 127 consecutive pediatric patients with World Health Organization Grade I and Grade II low-grade gliomas treated at Mayo Clinic between 1990 and 2005. Of those, 90 patients had complete removal of their tumor and 20 patients had subtotal resections with added radiation therapy. Results showed that greater than 89 percent of the patients are surviving more than 10 years later.

When combined with results from a previous Mayo Clinic study, this is the largest group of patients reported and was conducted through long-term follow-up by the Mayo Clinic team.

"This is great news for families because it shows that even if a complete surgery isn't possible, adding radiation to a less than complete surgery reduces their chances of tumor progression to yield the same outcome as if there was a complete removal," says Dr. Laack.

Other members of the research team included Shariq Khwaja, Nicholas Wetjen, M.D., and Paul D. Brown.

Im Focus: Turmoil in sluggish electrons’ existence

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...

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...
