This was tested in people. That is the most reliable kind of research we share.
These treatments are already offered today, and this study just looked back at records.
The short version
In Norway, more people now get treatment aimed right at the spots where their cancer spread.
What was studied. Researchers used two national health records in Norway. They looked at 20,210 people whose colon or rectal cancer had spread, from 2010 to 2023.
What they found. About 21% got treatment aimed at the spread itself, and most of that was surgery (87%). Five years later, 50% were alive after treatment for liver spread, and 62% after treatment for lung spread. After treatment for brain spread, 5% were alive at five years.
What this means, and what it doesn't
What it could mean: Treatment aimed at the spread is used more often now than it used to be. Results for spread in the liver and lung were fairly good. Spread to the brain is still much harder to treat.
What it doesn't mean: This is a look back at health records, not a trial. It does not prove that this treatment made people live longer. Who was chosen for treatment may explain part of the difference. The numbers are group averages, not a forecast for any one person. This is not a cure, and it does not change what your own doctor can offer you today.
