What You Need to Know Before You Apply

What is the purpose of this trial?

This trial will evaluate whether the following aspect of surgical technique influence outcome: Lymph node dissection. In some patients, scans taken before surgery show that a lymph node has cancer. Surgeons make sure to remove those affect lymph nodes and all other lymph nodes in the area. However, it is not known whether removing lymph nodes helps prostate cancer patients whose scans do not show positive nodes. In this study, patients with clear scans will either receive a lymph node dissection or not."

Do I need to stop my current medications for this trial?

The trial information does not specify whether you need to stop taking your current medications.

Is modified radical prostatectomy with pelvic lymph node dissection safe for humans?

The research articles focus on the practice and outcomes of radical prostatectomy with pelvic lymph node dissection for prostate cancer, but they do not provide specific safety data. However, this procedure is a standard treatment for high-risk prostate cancer, suggesting it is generally considered safe when performed by experienced surgeons. ^{1 2 3 4 5}

How does the lymph node template treatment differ from other prostate cancer treatments?

The lymph node template treatment during a modified radical prostatectomy for prostate cancer involves a specific approach to removing lymph nodes, which can be either limited or extended. This method is unique because it focuses on the diagnostic and therapeutic benefits of lymph node dissection, potentially impacting cancer-specific survival by addressing the burden of positive nodes rather than just the number of nodes removed. ^{6 7 8 9 10}

What data supports the effectiveness of the treatment Lymph node template in the clinical trial Modified Radical Prostatectomy for Prostate Cancer?

Research suggests that the extent of pelvic lymph node dissection (removal of lymph nodes) during surgery can impact long-term cancer outcomes in men with prostate cancer, indicating that a more thorough removal may be beneficial. ^{3 8 11 12 13}

Are You a Good Fit for This Trial?

This trial is for men aged 21 or older with prostate cancer who are scheduled for radical prostatectomy at MSKCC. It's open to those without positive lymph nodes on scans and no prior pelvic radiation therapy. The study includes patients regardless of whether they're eligible for both surgical modifications being tested.

Inclusion Criteria

I am 21 or older and scheduled for a specific prostate cancer surgery at MSKC.

I am 21 or older and scheduled for prostate cancer surgery at MSKCC.

You don't have to meet both requirements to participate in the study.

Exclusion Criteria

I have had a scan showing abnormal pelvic nodes or received pelvic radiation for prostate cancer.

I am not excluded by my choice of hemostatic agent use.

Timeline for a Trial Participant

Screening

What Are the Treatments Tested in This Trial?

Interventions

• Lymph node template

Trial Overview The trial is testing the effects of different surgical techniques during radical prostatectomy, including lymph node dissection versus none, and the use of a hemostatic agent to control bleeding. Patients will be randomly assigned to receive one technique or not.

How Is the Trial Designed?

Group I: Transverse versus vertical closure of the port site incision (Closed as of 9/30/2021) Experimental Treatment 1 Intervention

Group II: One vs. three days of antibiotic prophylaxis (Closed as of 9/30/2021) Experimental Treatment 1 Intervention

Group III: Lymphadenectomy vs. no lymphadenectomy Experimental Treatment 1 Intervention

In patients randomized to standard, only the nodal packet under the external iliac vein and above the obturator nerve will be dissected. For patients randomized to the modified template, the external iliac, hypogastric and obturator fossa nodal groups will be removed.No lymph nodes will be removed in patients randomized to the no PLND arm.

Group IV: Hemostatic agent vs. no hemostatic agent Experimental Treatment 1 Intervention
