Quantitative PET imaging finds early determination of effectiveness of cancer treatment
10-23-2007 · EurekAlert!With positron emission tomography imaging, seeing is believing: evaluating a patient's response to chemotherapy for non-Hodgkin lymphoma typically involves visual interpretation of scans of cancer tumors. Researchers have found that measuring a quantitative index -- one that reflects the reduction of metabolic activity after chemotherapy first begins -- adds accurate information about patients' responses to first-line chemotherapy, according to a study in the October issue of the Journal of Nuclear Medicine.

- Jefferson scientists see breast cancer gene activity from outside the body
11-28-2007 · EurekAlert!
Researchers at Jefferson Medical College and Jefferson's Kimmel Cancer Center in Philadelphia have used PET imaging to see hyperactive cancer genes inside breast tumors in laboratory animals, marking the first time such gene activity has been observed from outside the body. This technology might someday help physicians to detect and classify cancer, enabling them to find cancerous breast tumors as early as possible, and determine the appropriate treatment.

- MIT model could predict cells' response to drugs
07-30-2007 · EurekAlert!
MIT researchers have developed a model that could predict how cells will respond to targeted drug therapies. Models based on this approach could help doctors make better treatment choices and drug developers identify the ideal compound. In addition, the model could help test the effectiveness of drugs for a wide range of diseases, including cancer, arthirtis, and immune system disorders.
