Improvement in staging of prostate cancer

Three-dimensional transrectal ultrasonography (3D-TRUS) allows accurate 3D examination of pathological structures and prediction of extracapsular tumor extension.

180 randomly selected patiens with initial diagnosed prostate cancer participated in a study at the Medical University of Innsbruck. Dr. Michael Mitterberger and colleagues used 3D-TRUS, which provides ultrasonograms in three planes simultaneously, for local staging of prostate cancer.

“3D-TRUS can be used with no problems and is a simple procedure allowing exact assessement for staging prostate cancer,” said Dr, Mitterberger. “Locally confined and locally advanced prostate cancer can be differentiated with maximum convenience, reliability, and ease.”
3D-TRUS highly increase chances to detect pathological capsular perforation of the tumor: It predicted 44 of 53 cases correctly and features an overall accuracy of 96%.

The investigators conclude their report in the July issue of BJU International: “3D-Trus can be considered to guide the decision before a planned radical prostatectomy. If 3D-TRUS indicated locally advanced disease, the probability of capsular perforation or seminal vesicle invasion is very high.”
