Scientists at the University of California (UC), San Diego, have developed an experimental vaccine that could curb the spread of metastatic cancers to the lungs. The key ingredients of the vaccine are nanoparticles that have been engineered to target a protein known to play a central role in cancer growth and spread. The vaccine significantly reduced the spread of metastatic breast and skin cancers to the lungs in mice. It also improved the survival rate in mice with metastatic breast cancer after surgical removal of the primary tumor.

The findings were published in the Proceedings of the National Academy of Sciences in an article titled, “Viral nanoparticle vaccines against S100A9 reduce lung tumor seeding and metastasis… Continue reading.
