Trial of Modifications to Radical Prostatectomy

• Status: Recruiting
• Trial end date: 2023-07-01
• Target enrollment: 0
• Participant gender: Male

Summary

This study aims to determine how different ways of performing prostate cancer surgery affect patient outcomes, such as recurrence of cancer or regaining control of bladder function (continence) after surgery. Surgery to remove the prostate is known as a "radical prostatectomy". Surgeons know many things about the best way to do a radical prostatectomy. However, there is uncertainty about some methods of surgery.

All of the surgeons who are taking part in this study have used these techniques at different times. However, they are unsure as to what is the best approach. This trial will evaluate whether the following two aspects of surgical technique influence outcome:

Lymph node template. Prostate cancer can sometimes spread to the lymph nodes near the prostate. Surgeons often remove these lymph nodes to make sure that no cancer is left in the body. However, there is uncertainty about which lymph nodes to remove (the "template"). In particular, not all surgeons think that it is important to remove a large number of lymph nodes. Some believe that prostate cancer found in the lymph nodes is not aggressive. As a result, these surgeons feel that removing additional lymph nodes does not improve the chance that a patient will be cured. In the study patients will either have the standard lymph node dissection or a modified approach.

Port site incision. Some surgeries are conducted with the help of what is called a surgical "robot", or using a laparoscopic approach (sometimes known as "keyhole" surgery). The surgeons have to make small cuts ("incisions") in order to insert their surgical instruments. Some surgeons believe that the way in which this cut is made can affect the chance that a patient will develop a hernia in the months after surgery. This is when tissues in the abdomen protrude through the incision, creating a small bulge that has to be surgically corrected. In the study, patients will either have the incision made vertically or horizontally.

Antibiotics. About a week after surgery, you will return to the hospital to have your catheter removed. To guard against the chance of infection, you will be given antibiotics. These do help prevent infection, but are also harmful. Doctors are unsure whether to give a short course of antibiotics or whether patients really need several days of treatment. In the study, patients will receive antibiotics for either one or three days.
