Feasibility Study of Ultrasound Elastography Detecting Prostate Cancer

Feasibility Study of Ultrasound Elastography Detecting Prostate Cancer: A Pilot Study

The main purpose of this study is to determine the accuracy and feasibility (possibility) of Aixplorer® ShearWave Elastography (SWE™) Ultrasound System (made by SuperSonic Imagine, Inc.) for detecting prostate cancer in men undergoing radical prostatectomy.

The point estimate and its 95% confidence interval will be calculated using the exact binominal method. Identification of suspicious cancer tissue in a 12 prostate zone schema: Participants will undergo USE: Aixplorer® ShearWave Elastography (SWE™), (SuperSonic Imagine). Areas of the prostate with high suspicion for harboring cancer will be recorded in a 12 zone prostate schema. For study purposes the prostate will be divided into Zone 1(Left Lateral Base), Zone 2 (Left Base), Zone 3 (Right Base), Zone 4 (Right Lateral Base), Zone 5 (Left Lateral Mid), Zone 6 (Left Mid), Zone 7 (Right Mide), Zone 8 (Right Lateral Mid), Zone 9 (Left Lateral Apex), Zone 10 (Left Apex), Zone 11 (Right Apex), Zone 12 (Right Lateral Apex).

Inclusion Criteria:

• Men with prostate cancer who elect surgery as the primary treatment of their cancer and to be performed at the Moffitt Cancer Center.
• Biopsy confirmed prostate cancer with at least ten biopsies performed for diagnosis.
• Location of cancer specified in the pathology report.
• Pathology reviewed by Moffitt pathologist

Exclusion Criteria:

• Less than ten biopsies obtained at time of diagnosis.
• Location of cancer not specified.
• Pathology not reviewed by Moffitt pathologist.
