Trial of Modifications to Radical Prostatectomy

August 13, 2025 updated by: Memorial Sloan Kettering Cancer Center

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."

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

21 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

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

Study Plan

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Lymphadenectomy vs. no lymphadenectomy
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.
Procedure: Lymph node template
Inclusion of the external iliac, hypogastric and obturator fossa nodal groups in the template undergoing a Radical Prostatectomy. Modifying the template for lymph node dissection may lead to removal of additional affected nodes, reducing the chance of recurrence. .No lymph nodes will be removed in patients randomized to the no PLND arm.
Experimental: Transverse versus vertical closure of the port site incision (Closed as of 9/30/2021)
Procedure: Transverse versus vertical closure
Transverse versus vertical closure of the port site incision
Experimental: One vs. three days of antibiotic prophylaxis (Closed as of 9/30/2021)
Drug: antibiotic prophylaxis
One vs. three days of antibiotic prophylaxis at catheter removal
Experimental: Hemostatic agent vs. no hemostatic agent
Drug: Hemostatic Agent
For the patients randomized to routine indwelling HA agent use, the operating surgeon may choose to use either Surgicel™, Surgicel SNoW™, Arista™, FloSeal or surgeon's choice HA directed at the prostatic fossa, ligated dorsal vein complex, or neurovascular bundles. Because there is no standard HA or method of application, the surgeon will apply the HA according to the surgeon's experience and document both the HA used, and the location applied in the operative report. For patients randomized to no routine indwelling HA use, surgeons will only apply a HA if they are unable to achieve hemostasis using traditional means or feel it would be unsafe to complete the operation without using a HA for additional hemostasis. Providers in either arm may use HA as needed provided the intention is not to leave the HA indwelling.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Patient-reported hernia
Time Frame: 1 year
Patient-reported hernia is a routine assessment on post-operative questionnaires completed by prostate cancer patients at MSKCC. The questionnaire asks about hernia near the surgical scar and if there has been a need for surgical repair of the hernia.
1 year

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
To evaluate whether a modification to the template for lymph node dissection reduces biochemical recurrence rates
Time Frame: 2 years
Biochemical recurrence is defined as any postoperative PSA of 0.2 ng / mL or higher, or treatment with hormones, radiotherapy or chemotherapy starting six months or more after radical prostatectomy.
2 years
urinary tract infection (UTI)
Time Frame: within 10 days
urinary tract infection (UTI) within 10 days of catheter removal. We will use the CDC's definition of UTI: symptomatic UTI diagnosed in patients with positive urine cultures (≥100,000 microorganisms per cm3) and at least one of the following signs or symptoms with no other recognized cause: fever (>38oC), urgency, frequency, dysuria or suprapubic tenderness.50 UTI is routinely captured by clinical staff as a surgical complication.
within 10 days
