This looks across many earlier studies rather than running a new one.
It has been used in people, but only in a few small studies, so it is not proven for this part of the brain yet.
The short version
Doctors used a thin laser probe to heat and kill brain growths that are hard to reach by surgery.
What was studied. Researchers pooled nine earlier studies of a laser heat treatment guided by MRI scans. The studies covered 99 patients with 102 growths in the back of the brain.
What they found. The treated spot stayed under control in 79.3% of growths. For cancer that had spread to the brain from elsewhere, it was 88.4%. About 7.5% of patients needed more treatment at that spot. Lasting nerve problems happened in 10.1% of patients, and 1.0% died from the procedure itself.
What this means, and what it doesn't
What it could mean: Surgery in this part of the brain can be very risky. For some people, this laser treatment may be another option to talk about. The authors say it may be reasonable in hard cases, after a team of doctors reviews it.
What it doesn't mean: This does not prove the treatment works here. The authors call their numbers exploratory, not final. Only nine small studies were pooled, and they differed a lot from each other. Patients were followed for 3.5 to 31.2 months, so long-term results are unknown. This is not a cure, and it is not standard care for this part of the brain.
