This was tested in people. That is the most reliable kind of research we share.
This looked back at records of real patients, but it is not a new treatment.
The short version
Doctors found that wider tumor spread at the start raised the chance of the tumor coming back.
What was studied. Doctors looked back at the records of 254 patients treated at 10 hospitals in Korea. All of them had a tumor called craniopharyngioma, found before age 18.
What they found. The tumor came back in 66 patients (26.0%). Of those, 45 had it come back once, 15 had it twice, four had it three times, and two had it five times. Tumors that had spread more widely when first found were more likely to come back. Growth hormone treatment after surgery was not linked to the tumor coming back.
What this means, and what it doesn't
What it could mean: If a child's tumor had spread widely when it was found, the care team may want to watch more closely with regular scans. The results also offer some comfort about growth hormone treatment. In this group, it did not appear to raise the chance of the tumor coming back.
What it doesn't mean: This does not mean a new treatment is coming. It is not a cure, and it is not a promise about any one child. The study looked back at old records, so it can show patterns but cannot prove what causes what. Earlier studies have not all agreed. Talk with your own care team before changing anything.
