Ultrasound Based Transperineal Robotic Biopsy of the the Prostate (BxB)

The recruitment status of this study is unknown. The completion date has passed and the status has not been verified in more than two years.
Verified May 2006 by Singapore General Hospital.

The objective of the study is to examine the effectiveness and accuracy of the BioXbot in prostate biopsy as opposed to transrectal biopsy. This evaluation of the efficacy of both the procedures is based on:

  • Uptake rate
  • Peripheral zone reachability
  • Needling accuracy
  • Procedure execution time
  • Post operative discomfort or trauma experienced by patient
  • Quality and type of tissue sample extracted
  • Adverse and unanticipated side-effects on patient after the procedure and recording any unexpected reactions

Condition Intervention Phase
Previous Negative Biopsy Procedure: Robotic Transperineal Biopsy Phase 1 Phase 2

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Diagnostic
Official Title: Study of Prostate Cancer Detection With in House Developed Robot

Further study details as provided by Singapore General Hospital:

Primary Outcome Measures:
  • Cancer Detection [ Time Frame: 2 years ]
    to detect any undetected cancer in Patietns undergoing saturation biopsy

Secondary Outcome Measures:
  • Accuracy and Repeatability [ Time Frame: 6 months ]
    To be accurate in biopsy position (+/- 2mm) and be able to go back to the same position if patient undergoes treatment.

Estimated Enrollment: 250

Estimated Study Completion Date: June 2011
Estimated Primary Completion Date: January 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
