This was tested in people. That is the most reliable kind of research we share.
Doctors looked back at care already given to 12 people at one hospital, so it is not proof.
The short version
In a small study, the transplant worked best when it was done right after the cancer went away.
What was studied. Doctors looked back at 12 patients with lymphoma in the brain or spinal cord. Eight had the type that starts there, and four had the type that spread there. All 12 got high dose chemo and then a transplant of their own stem cells.
What they found. Nine patients had the transplant soon after their cancer went away with chemo. All nine were still cancer free at follow up, which ran from 147 to 1322 days. Three patients had the transplant later, after many other treatments. Their cancer came back within 51 to 125 days, and they died of it.
What this means, and what it doesn't
What it could mean: Timing may matter. If your team plans this transplant, doing it soon after the cancer goes away may give a better chance than waiting until other treatments stop working.
What it doesn't mean: This is not a cure and it is not proof. It was a look back at the records of just 12 people at one hospital. There was no comparison group, so it cannot show that timing alone caused the results. The authors say more study is needed. Your own case may be different, so talk with your care team.
