A computer tool tries to spot a key gene change in brain tumors
Original title: FOCUS: a feature optimization and cascaded unified screening strategy for computer-aided pathology-based glioma molecular subtype classification.
How far along is this research?
- Lab cells
- Animals
- Review
- Tested in people
This was done on cells in a lab, not in people. It is a very early step.
This was only a computer test run on stored tumor images.
The short version
Scientists built a computer tool that looks at tumor images to find an important gene change.
What was studied. Researchers made a computer tool called FOCUS. It read tumor slide images from 73 patients. The goal was to tell if the tumor had a gene change called IDH gene change: A small change in a tumor's IDH gene. It is the first thing your team looks at when naming an adult glioma, and it can affect which treatments are offered. Your pathology report says whether your tumor has it. See the glossary.
What they found. On images from 73 patients, the tool had an accuracy score of 0.902. So it picked the right answer much of the time. The tool was also built to show which image details it used, so people can check its work.
What this means, and what it doesn't
What it could mean: Knowing the IDH gene change: A small change in a tumor's IDH gene. It is the first thing your team looks at when naming an adult glioma, and it can affect which treatments are offered. Your pathology report says whether your tumor has it. See the glossary gene status helps doctors name the tumor type and plan care. Right now that testing can be slow and costly. A tool like this might one day help labs give answers faster.
What it doesn't mean: This is not a treatment, and it is not a cure. It is early computer work, not care you can get. It was only tried on stored images from 73 patients. It did not guide anyone's real treatment. Much more testing is needed before any clinic could use it.
