UCSF research shows that 1-2 punch blocks tumor growth, invasion and metastasis in mice

Simultaneous targeting of two different molecules in cancer is an effective way to shrink tumors, block invasion, and stop metastasis, scientists at the University of California, San Francisco (UCSF) have found -- work that may improve the effectiveness of combination treatments that include drugs like Avastin. The two-target approach, tested in mice with a type of cancer known as neuroendocrine pancreatic tumors, may have broad application for treating a wide variety of cancers, the UCSF team said. The drugs used in the tests belong to classes of pharmaceuticals that are either on the market or under development in clinical trials. Clinical trials also are already underway to gauge effectiveness of the approach in humans with prostate cancer, breast cancer, and other tumor types. The UCSF study, described in the journal Cancer Discovery this week, is the first to show how the drug combination works in the laboratory.
