CHICAGO, IL, USA (UroToday.com) - Traditional PET scanning with 18F-fluorodeoxyglucose for renal cell cancer has been largely of little use. However, the use of 11C-Acetate may change this situation completely.

 

In this study of Bosniak III and IV renal cysts, ALL renal cell cancers (i.e. 10/10) greater than 1.5 cm were detected while lesions 1 cm or smaller could not be imaged. Tumors at the 1.5 cm size were imaged in 3 of 5 (60%) cases. This is quite exciting news, as if these data are corroborated in a larger series we could have a very effective manner for distinguishing which Bosniak 3 cysts require exploration provided the solid portion of the cyst is greater than 1.5 cm. Other questions arise, such as whether the 11C-Acetate PET will be of value for solid renal masses from the standpoint of differentiating benign from malignant entities?
