Researchers from Francis Crick Institute and the University of Copenhagen said that by using experimental drugs, they were able to stop the fibroblasts from stiffening the tissue around tumors. Thus the healthy tissue trapped the cancer cells, blocking their movement away from the tumor.
They tested the new approach on mice, and the results showed that targeting fibroblasts reduced the movement of cancer cells from the tumor to the lungs and liver through the blood stream.
Since most deaths from cancer are caused when cancer cells travel to new sites in the body and grow as secondary tumors, the new method may lead to better ways to control the disease and save more lives, according to the researchers.
"This could be an exciting new way to harness the potential of the healthy tissue surrounding cancers to contain and restrain aggressive tumors, stopping cancer cells from breaking away and moving to new places in the body," said Dr. Erik Sahai from the Francis Crick Institute. He is the co-lead author of the study.
