Traditionally, tumor diameter is considered the strongest prognostic factor when assessing patients with renal cortical tumors (RCT). However, three-dimensional (3D) tumor volume calculated from imaging has been demonstrated to be an independent predictor of cancer control.
The conclusion is from a study presented at the 2007 American Urological Association (AUA) annual meeting in Anaheim, California, May 19-24.
Investigators [1] from the NewYork-Presbyterian Hospital/Columbia University Medical Center evaluated the correlation between preoperative 3D imaging and pathologic tumor volume. Tthe team determined that preoperative 3D imaging tumor volume correlates to pathologic 3D volume and independently predicts disease-free survival in patients with RCTs.
