- Tested in people
This was tested in people. That is the most reliable kind of research we share.
Doctors looked back at records of people already treated, so this is not proof.
The short version
Saving and giving back a patient's own blood during meningioma surgery was not linked to the tumor coming back more often.
What was studied. Doctors reviewed records of 988 adults who had meningioma surgery and heavy blood loss. Some had their own blood saved and given back during surgery, and some did not.
What they found. In all, 89 of the 988 people had the tumor come back, or 9.0%. The tumor came back less often in those who got their own blood back, 7.9% compared with 14.9%. People were followed for 60 months on average.
What this means, and what it doesn't
What it could mean: If you need meningioma surgery and lose a lot of blood, saving your own blood may still be an option. This study did not find a link to the tumor coming back more often. That may ease one worry for patients and surgeons.
What it doesn't mean: This does not mean saving your blood stops a tumor from coming back. It is not a treatment, and it is not a cure. The study only looked back at old records at one hospital, so other things could explain what they saw. It also only included people who lost a lot of blood. Choices about surgery and blood are still up to you and your care team.
