Cancer center may have found link between GIST, targeted therapy

5/19/2009

ORLANDO, Fla. Researchers at Fox Chase Cancer Center uncovered a genetic pattern that may help predict how gastrointestinal stromal tumor patients respond to the targeted therapy Gleevec (imatinib mesylate). Moreover, their findings point to genes that could be suppressed in order to make these tumors respond more readily to imatinib.

"Imatinib has been the first drug that has really made a dent in GIST progression – up to 80% response – yet some GIST patients have little or no response to the drug," commented Lori Rink, a postdoctoral fellow in the laboratory of Andrew Godwin at Fox Chase. "We are looking to see how we can help clinicians make better decisions in applying imatinib or additional therapies to their GIST patients,” she said. "Our data indicate that if we can alter the activity of some of these KRAB-zinc finger proteins, we may be able to enhance the effectiveness of imatinib therapy.”

Rink presented their findings at the 2009 Annual Meeting of the American Society of Clinical Oncology.
