Positron emission tomography superior to standard evaluation tools in measuring treatment response

Standard evaluation imaging missed 80 percent of responders

Positron Emission Tomography (PET) was much more sensitive and more accurate than conventional imaging methods in detecting response to treatment in sarcoma patients, according to a UCLA study that is among the first to directly compare PET to CT scanning.

The study has important implications for patients. If conventional imaging fails to detect treatment response, oncologists may discontinue therapies that in fact are working and study participants may be dismissed from clinical trials that are actually helping them. Conversely, if a patient is not responding, using PET scanning to evaluate response could help prevent them from undergoing toxic therapies that aren�t working.
