This was tested in people. That is the most reliable kind of research we share.
This looked back at past patient records, not a trial that tested surgery.
The short version
Women who had surgery on the main breast tumor lived longer, but this study cannot prove surgery was the reason.
What was studied. Researchers looked back at records of 1,827 women with stage IV triple-negative breast cancer, diagnosed between 2010 and 2020. The cancer had already spread to the liver, lung, or brain. Of these women, 543 had surgery on the main breast tumor and 1,284 did not.
What they found. The team matched 507 pairs of women who were alike in other ways. Survival time was 15 months in the surgery group and 9 months in the group without surgery. Survival time counting only deaths from breast cancer was 15 months with surgery and 10 months without.
What this means, and what it doesn't
What it could mean: Surgery on the main tumor may be worth asking your care team about. It might help some people live longer, even after the cancer has spread. The right choice depends on your health, where the cancer is, and how treatment is working.
What it doesn't mean: This is not a cure, and it is not proof that surgery makes people live longer. The study looked back at old records. It did not test surgery in a trial. Women chosen for surgery may have been healthier to start with. That alone could explain the difference. The authors say these findings are an idea to test, not an answer. Surgery is not right for everyone in this situation.
