Study summary

This pilot clinical trial studies magnetic resonance imaging (MRI)-transrectal ultrasound (TRUS) fusion image-guided prostate biopsy following radical prostatectomy in patients with prostate cancer. Diagnostic procedures, such as MRI-TRUS fusion image-guided prostate biopsy may help find and diagnose prostate cancer

Read the detailed description

PRIMARY OBJECTIVES:

I. To evaluate accuracy of the new image-guided targeted needle biopsy using the ex-vivo human prostate as obtained from fresh radical prostatectomy specimens.

OUTLINE: Patients undergo robotic radical prostatectomy, followed by 3 MRI-TRUS fusion image-guided prostate biopsies.

What researchers measure

Primary outcomes

  1. Number of times the first biopsy needle is placed within 3.0 mm of the center lesion

    A likelihood ratio test will be used to test for independence among lesions within a prostate (corresponding to a lack of systematic MRI-TRUS image distortion and implying that, overall, 1st biopsies to a lesion within one prostate are as likely to accurate as in another prostate).

    Time frame: One month after last patient enrolled is taken off study

  2. Number of times the second biopsy needle is placed within 3.0 mm of the center lesion

    A likelihood ratio test will be used to test for independence among lesions within a prostate (corresponding to a lack of systematic MRI-TRUS image distortion and implying that, overall, 1st biopsies to a lesion within one prostate are as likely to accurate as in another prostate).

    Time frame: One month after last patient enrolled is take off study

Secondary outcomes

  1. Average distance of the first needle to the center of the lesion

    A nested (random effects) analysis of variance (ANOVA) will be used to analyze the distance of the first needle from the center of the lesion. Standard error or 95% confidence interval will be calculated.

    Time frame: One month after last patient enrolled is taken off study

  2. Average distance of the second needle from the first needle minus 2.0 mm

    A nested (random effects) ANOVA will be used to analyze the distance of the first needle from the center of the lesion.

    Time frame: One month after last patient enrolled is taken off study

  3. Average distance of the third needle from the first needle minus 2.0 mm

    A nested (random effects) ANOVA will be used to analyze the distance of the first needle from the center of the lesion.

    Time frame: One month after last patient enrolled is taken off study
