Tumor treating fields with chemo linked to longer survival in a China study

Original title: Tumor treating fields plus temozolomide maintenance after radiochemotherapy in Chinese grade 4 gliomas: Efficacy and predictive biomarkers.

How far along is this research?

This was tested in people. That is the most reliable kind of research we share.

This treatment is already approved and given to patients today.

The short version

People who used tumor treating fields along with their chemo lived longer in this study.

What was studied. Doctors in China looked back at 64 people with grade 4 glioma: A tumor that starts in the glial cells, the support cells of the brain and spinal cord. Gliomas are graded 1 to 4 by how fast they tend to grow. See the glossary. All had surgery, then radiation and chemo. 22 of them also used tumor treating fields.

What they found. The people who used tumor treating fields lived longer. Typical survival was 15 months in that group. It was 11 months in the group without the device. The time before the tumor grew again was not clearly better. People whose tumors had a certain pair of chromosome changes did worse.

What this means, and what it doesn't

What it could mean: Adding tumor treating fields to chemo may give some people extra time. This device is already used for this kind of brain tumor. It is fair to ask your care team if it fits your case.

What it doesn't mean: This does not mean the device stops the tumor. It is not a cure. The study was small and looked back at old records. People were not picked at random for each group. So other things may explain the difference. The results for smaller groups of patients are early hints only. Bigger studies are needed to be sure.
