Prostate Biopsy: Reducing Complications and Improving Efficacy (ProBE-PC Randomized Trial)

Prostate Biopsy: Efficacy and Complications


Lead sponsor: Albany Medical College

Brief Summary

This study evaluates the difference between 2 prostate biopsy methods. Half of the subjects will have the prostate biopsy method using a needle through the rectum and the other half will have the biopsy method using a needle through the skin to reach the prostate.This research study hopes to scientifically determine if one biopsy method is better than the other in reducing complications and improving cancer detection.

Detailed Description

There are two ways to take biopsy (tissue) samples from the prostate. The more commonly used method is trans-rectal needle biopsy of the prostate (TR-Bx) with a needle inserted through a probe in the rectum to reach the prostate.

A newer approach is Trans-perineal biopsy (TP-Bx) with a needle inserted directly through the skin to reach the prostate.

Previously, TP-BX was usually only performed in the outpatient surgical setting. Now we are able to perform these in the office.

Both of these biopsy methods are considered standard medical care in the United States.

With the TR-Bx, there has been increasing risk of infections and hospital admissions noted throughout the United States. The newer approach of biopsy TP-Bx may cause fewer infections and may have a higher accuracy of finding cancer.

The hypothesis of the study is that Office-based transperineal prostate biopsy will have a lower rate of infectious complications and increased cancer detection when compared to transrectal biopsy.

Inclusion Criteria:

- All patients who are scheduled to undergo prostate biopsy for suspected prostate cancer as part of their regular medical care

Exclusion Criteria:

- Patients with anatomic variations

- No access to rectum (due to previous rectal surgery)

- Any abnormalities of the perineal skin (e.g. infection)

- Patients whose procedure requires sedation or general anesthesia

- Patients who are scheduled to undergo "limited" sampling (usually 2-3 core needle samples) due to the following reasons:

- Patients who are unable to temporarily stop anticoagulation medications

- Immunocompromised patients who are at increased risk of infection

- Physician preference (e.g. older age; low risk of having cancer)
