(HealthDay News) -- California researchers say they have developed molecular "smart bombs" that stop pancreatic and kidney cancer from spreading in mice while causing fewer side effects and damage to healthy surrounding tissues than traditional chemotherapy.
A team from the University of California, San Diego, designed a "nanoparticle" anti-cancer drug delivery system that zooms in on a protein marker called integrin avB3, which is found on the surface of certain tumor blood vessels. The marker is tied to the development of new blood vessels and malignant tumor growth.
While the system had little impact on primary tumors, it halted the metastasis of pancreatic and kidney cancers throughout the bodies of mice. Cancer metastasis normally is much harder to treat than the primary tumor, and it usually leads to the patient's death.
The findings were published in this week's online issue of the Proceedings of the National Academy of Sciences.
