Trial of Modifications to Radical Prostatectomy

A Randomized Trial of Modifications to Radical Prostatectomy

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."

Inclusion Criteria:

• Patients do not have to be eligible for both modifications to be included in the study.

Lymphadenectomy vs no lymphadenectomy:

• Patients 21 years or older scheduled for radical prostatectomy for treatment of prostate cancer with one of the consenting surgeons at MSKCC

Hemostatic agent vs. no hemostatic agent

• Patients 21 years or older scheduled for minimally invasive radical prostatectomy for the treatment of prostate cancer with one of the consenting surgeons at MSKC

Exclusion Criteria:

Lymphadenectomy vs no lymphadenectomy

• Presence of positive/suspicious pelvic nodes on MRI, CT or PSMA scan (positive/suspicious defined as a pelvic node >15mm in short axis on CT or MRI, a PSMA avid node, or a node with abnormal morphology such as roundness or irregularity or loss of fatty hilum)
• Any prior pelvic radiation therapy used to treat prostate cancer

Hemostatic agent vs. no hemostatic agent

• No additional exclusion criteria
