Prostate Cancer: Radical Prostatectomy
Radical prostatectomy is an operation to remove the prostate gland and tissues surrounding it. This usually includes the seminal vesicles and some nearby lymph nodes. Radical prostatectomy can cure prostate cancer in men whose cancer is limited to the prostate.
Who Should Undergo Radical Prostatectomy?
Men younger than age 75 with limited prostate cancer who are expected to live at least 10 more years tend to get the most benefit from radical prostatectomy.
Before performing radical prostatectomy, doctors first try to establish that the prostate cancer has not spread beyond the prostate. The statistical risk of spread can be determined from tables comparing the results of a biopsy and PSA levels. Further testing for spread, if needed, can include CT scans, bone scans, MRI scans, and ultrasound.
If it appears that the prostate cancer has not spread, a surgeon (urologist) may first offer other options besides surgery. These can include radiation therapy, hormone therapy, or simply observing the prostate cancer over time, since many prostate cancers grow slowly.
Types of Radical Prostatectomy
The prostate gland lies just under the bladder, in front of the rectum. Surgeons choose from two different approaches to reach and remove the prostate during a radical prostatectomy. One is a traditional approach known as open prostatectomy. The other, more recent approach is minimally invasive. There are two minimally invasive procedures used in radical prostatectomy: laparoscopic prostatectomy and robot-assisted laparoscopic prostatectomy.
In this traditional method of radical prostatectomy, the surgeon makes a vertical 8- to 10-inch incision below the belly button. Radical prostatectomy is performed through this incision. In rare cases, the incision is made in the perineum, the space between the scrotum and anus.
In laparoscopic prostatectomy, surgeons make several small incisions across the belly. Surgical tools and a camera are inserted through the incisions, and radical prostatectomy is performed from outside the body. The surgeon views the entire operation on a video screen.
Robot-assisted laparoscopic prostatectomy
Small incisions are made in the belly, as in regular laparoscopic prostatectomy. A surgeon controls an advanced robotic system of surgical tools from outside the body. A high-tech interface lets the surgeon use natural wrist movements and a 3-D screen during radical prostatectomy.
