Study Details

Study Description

Brief Summary

The purpose of this clinical trial is to determine if prostate-capsule-sparing cystectomy improves functional outcomes without comprising oncologic outcomes in male patients receiving a radical cystectomy. Patients will be randomized to one of two groups: prostate capsule-sparing radical cystectomy or nerve-sparing radical cystectomy. Patients will be monitored following standard of care guidelines and clinical data will be collected. Patients in both groups will be asked to complete an erectile function questionnaire at multiple timepoints. Patients who receive an orthotopic neobladder will be asked to complete a questionnaire to monitor urinary function at multiple timepoints. Patient adverse events will be monitored to ensure patients safety.

Detailed Description

The purpose of this study is to determine if prostate capsule-sparing cystectomy improves functional outcomes without compromising the oncologic outcomes in patients with bladder cancer. The comparison arm will be patients undergoing nerve-sparing radical cystectomy. Participants will be randomized to receive either a nerve-sparing radical cystectomy or a prostate capsule-sparing radical cystectomy. Patients will be monitored following standard of care guidelines every 3-months post-operatively up to and including 24 months post-operatively. As part of standard of care post-operative follow-up patients will have routine history and physical exams, urine cytology, urine culture, Complete Blood Count (CBC), Comprehensive Metabolic Panel (CMP), and Prostate Specific Antigen (PSA). Standard of Care diagnostic imaging will also occur. The Sexual Health Inventory for Men (SHIM) Questionnaire will be given to patients 6-weeks post-operatively and every 3-months post-operatively up to and including 24-months post-operatively. To measure urinary function in patients who receive orthotopic neobladder, the Validated Pad Questionnaire will be given 6-weeks post-operatively and every 3-months post-operatively up to and including 24-months post operatively. Adverse Events will be monitored in both groups as defined by the CTCAE 5.0 guidelines.

Arms and Interventions

Arm Intervention/Treatment
Other: Prostate Capsule-Sparing Radical Cystectomy

Patients randomized to this arm will receive the prostate capsule-sparing surgery performed in the form of standard simple prostatectomy. Patients will also have a cystectomy with one of the following urinary diversions: ileal conduit, Indiana Pouch, or orthotopic neobladder.

Outcome Measures

Primary Outcome Measures

  1. Change in Functional Outcomes as assessed by the Sexual Health Inventory for Men (SHIM) [Baseline, 6 weeks-post operatively, 3-months post-operatively, 6-months post-operatively, 9-months post-operatively, 12-months post-operatively, 15-months post-operatively, 18-months post-operatively, 21-months post-operatively, 24-months post-op]

    Comparison of functional outcomes focusing on preservation of erectile function in patients undergoing cystectomy for bladder cancer. Functional Outcomes will be measured by the Sexual Health Inventory for Men (SHIM) Questionnaire. The Sexual Health Inventory for Men defines the following ranges of Erectile Dysfunction (ED): 1-7 is Severe ED, 8-11 Moderate ED, 12-16 Mild to Moderate ED, and 17 to 21 is Mild ED.

Secondary Outcome Measures

  1. Change in urinary function in patients with orthotopic neobladder as assessed by the Validated Pad Questionnaire [Baseline, 6 weeks-post operatively, 3-months post-operatively, 6-months post-operatively, 9-months post-operatively, 12-months post-operatively, 15-months post-operatively, 18-months post-operatively, 21-months post-operatively , 24-months post-op]

    Urinary function in patient with orthotopic neobladder urinary diversions measured using the Validated Pad Questionnaire. The Validated Pad questionnaire will be used to determine the percentage of patients utilizing 1 to 2 pads versus 2 or more pads for night and day, respectively.

  2. Change in overall patient survival [Baseline, 6 weeks-post operatively, 3-months post-operatively, 6-months post-operatively, 9-months post-operatively, 12-months post-operatively, 15-months post-operatively, 18-months post-operatively, 21-months post-operatively, 24-months post-op]

    Comparing the overall survival of patients in both arms of the study

  3. Change in disease specific status [Baseline, 6 weeks-post operatively, 3-months post-operatively, 6-months post-operatively, 9-months post-operatively, 12-months post-operatively, 15-months post-operatively, 18-months post-operatively, 21-months post-operatively, 24-months post-op]

    Comparing the status of disease specific in both arms of the study

  4. Soft tissue surgical margin rate as assessed by pathology [Up to 4-weeks after surgical intervention]

    Pathologists will examine the soft tissue surgical margin rate to determine positive or negative soft tissue surgical margin.

  5. Safety as assessed by adverse events experienced by study participants [Up to 24-months post-operative]

    Comparing the differences in adverse events (grades 2-5) as experienced by the participants of in each study arm. The grading of adverse events are defined by the CTCAE 5.0 guidelines.
