Nationwide study confirms PET as the most powerful imaging tool in cancer ...( Reston Va.With the most recent relea...),Health
Reston, Va.With the most recent release of data from the National Oncologic PET Registry (NOPR), researchers may have reached the moment of critical mass by confirming the effectiveness of positron emission tomography (PET) in the monitoring of tumor activity across a wide range of cancers.
"During the first year of the study, we verified that PET finds more areas of active cancer than other imaging tools and leads, in some cases, to earlier initiation of subsequent treatment," said Bruce E. Hillner, M.D., professor of medicine at Virginia Commonwealth University in Richmond, Va., and lead author of the article. "We noted that PET has a clinically significant impact on cancer management, resulting in a change in treatment in more than one out of three casesor 36 percent of the time."
In the article, published in the December issue of The Journal of Nuclear Medicine, researchers reported results by cancer type for the first two years of data collected from nearly 41,000 PET studies conducted at more than 1,300 cancer centers nationwide. Analysis was restricted to the use of PET for staging, restaging or detection of suspected recurrences in patients with pathologically proven cancers.
Study data released in March 2008 showed a striking consistency of the impact of PET on referring physicians' intended management plans. At that time, NOPR researchers felt that the significance of the evidence was such that they formally asked the Centers for Medicare and Medicaid Services (CMS) to reconsider the current National Coverage Determination on oncologic use of PET.
"As a result of the data, the follow-up question for the second year was: Does the impact of PET vary between cancers?" explained Hillner. "We found that it did not vary significantly, and that changes in treatment plans for rare cancerssuch as stomach cancerclustered around the same one-third mark as the more common cancers. As a result, we believe that coverage f
