Answer

For patients found to be at intermediate risk on the basis of established prognostic factors, Brennan and colleagues report that gene expression signatures may permit classification into intermediate-good prognosis and intermediate-poor prognosis groups. The authors note that their findings require validation, but they observe that tests that routinely measure expression of hundreds of genes are already commercially available. [34]
