Results. Four studies were included with a total of 3225 patients. The sensitivity and specificity for DRE as a predictor of prostate cancer in symptomatic patients was 28.6 and 90.7%, respectively. The positive and negative predictive values were 42.3 and 84.2%, respectively.
Can a DRE detect prostate cancer?
Prostate cancer can often be found early by testing for prostate-specific antigen (PSA) levels in a man's blood. Another way to find prostate cancer is the digital rectal exam (DRE). For a DRE, the doctor puts a gloved, lubricated finger into the rectum to feel the prostate gland.
Which is more accurate PSA or DRE?
DRE is less effective than the PSA blood test in finding prostate cancer, but it can sometimes find cancers in men with normal PSA levels.

What can a doctor tell from a DRE?

How long after DRE can I get PSA?
In most patients, peak levels were found between 30 and 60 min after DRE. Based on the results, it is concluded that after DRE it is prudent to wait 3 days before PSA is determined.
Why is the PSA drawn before the DRE?
To help ensure an accurate reading, the blood draw for the PSA test must be done prior to the DRE to avoid any stimulation of the prostate gland, which can increase the PSA level. Similarly, ejaculation within 48 hours prior to a man's blood draw can result in an elevated level of PSA.
Is a DRE necessary?
The DRE is a test that physicians should offer to their patients, noting that it is not essential but that it can, occasionally, have results that are critically important. No physician should insist on giving this test to a man at no other particular or well-defined risk for prostate cancer.

How painful is a biopsy of the prostate?
You will feel some pressure when the probe is inserted, but it is usually not painful. Usually between 6 – 12 (sometimes more) prostatic tissue samples are obtained and the entire procedure lasts about 10 minutes. A local anesthetic can be used to numb the area and reduce any pain.
What are the signs that prostate cancer has spread?
Prostate cancer can spread to the lymph nodes in the groin area, or to other parts of the body. The most common symptoms are swelling and pain around the area where the cancer has spread.
