About this trial

This is an interventional treatment trial for Prostate Cancer focused on measuring prostate cancer, radical prostatectomy, robot-assisted radical prostatectomy, prostatectomy, nerve sparing, Retzius, quality of life, urinary incontinence, sexual function

Eligibility Criteria

40 Years - 80 Years (Adult, Older Adult)MaleDoes not accept healthy volunteers

Inclusion Criteria:

  • clinically localized prostate cancer
  • able to read and speak English or Spanish
  • no previous history of head injury, dementia or psychiatric illness
  • no other concurrent cancer
  • estimated life expectancy of 10 years or more
  • biopsy proven prostate cancer

Exclusion Criteria:

  • evidence of metastases
  • Prostate specific antigen (PSA) greater than 30 ng/mL

Arms of the Study

Arm 1

Arm 2

Arm Type

Active Comparator

No Intervention

Arm Label

Retzius sparing

Conventional (non-Retzius) nerve sparing

Arm Description

Using the Retzius technique, the surgeon will remove the prostate in a way that preserves a portion of the nerves and tissue structures that are typically removed during the conventional technique.

A non-Retzius nerve sparing technique will be performed, according to surgeon's preference--nerve sparing during radical prostatectomy is performed with significant variation and there is an absence of universally agreed upon steps or techniques.

Outcomes

Primary Outcome Measures

Number of Treatment-Related Adverse Events as Assessed by Common Terminology Criteria for Adverse Events (CTCAE) v5.0
The investigators will obtain patient-reported complications and adverse events captured from patient's medical record.
Change in Patient-reported Health-Related Quality of Life (HRQOL) Scores as Assessed by Expanded Prostate Cancer Index Composite for Clinical Practice (EPIC-CP)
Patients will fill out the EPIC-CP questionnaire. The EPIC-CP is a 10-item questionnaire assessing five health-related quality of life domains: urinary function, urinary irritation, bowel function, sexual function, and hormonal issues. All questions are about patients' health and symptoms in the last four weeks. Each domain is scored out of 12 points, with higher scores indicating more complications. In total, the EPIC-CP score is the final sum of the 5 domains. The EPIC-CP is scored out of 60 points, with higher scores indicating more issues related to overall prostate cancer quality of life.
Change from Baseline in Prostate Specific Antigen (PSA) value on Laboratory Reports up to 24 Months Following Surgery
The investigators will obtain patient's PSA values from their medical record, at baseline and up to 24 months post-surgery. Patient PSA levels are obtained from standard of care blood tests, and PSA values are measured in ng/mL.

Secondary Outcome Measures

Change in Baseline in Patient-Reported Penile Shortening as Assessed on Questionnaire
Patients will fill out a validated, 5-item questionnaire assessing penile shortening, self-esteem, and presence of erections. Question 1 assesses patients' perceived penile length post-surgery, compared to penile length at 30 years of age. It consists of two possible responses: Yes or No. Questions 2 and 3 assesses patients' ability to obtain and quality of spontaneous morning erections and sexual activity-related erections. It consists of five possible responses: ranging from "No erections" to "Erections always sufficient". Question 4 is a visual digital scale assessing patients' present quality of life. It is scored on a scale of 1-7, with higher scores indicating high quality of life. Question 5 is a visual digital scale assessing patients' present self-esteem. It is scored on a scale of 1-7, with higher scores indicating high self-esteem.
Change in Baseline in Patient-Reported Penile Deformity as Assessed on Questionnaire
Patients will fill out a validated, 3-item questionnaire assessing presence of Peyronie's disease. Question 1 assesses penile hardening in the flaccid state. Question 2 assesses penile curvature in the erect state. Question 3 assesses pain associated with erection. Each question consists of two possible responses: Yes or No.
Change in Patient-reported Treatment Regret Scores as Assessed by Questionnaire
Patients will fill out a validated, 5-item questionnaire assessing feelings toward treatment regret. Each item is scored on a 5 point scale ranging from "Strongly Agree" to "Strongly Disagree". Responses are converted to a score ranging from 0-100, with higher scores indicating more regret.

5. Study Description

Brief Summary
The investigators propose a prospective study to assess recovery of urinary and sexual function by nerve sparing techniques after radical prostatectomy.
Detailed Description
Subjects will be randomized in a 1:1 ratio to Retzius nerve sparing versus non-Retzius nerve sparing to compare cancer outcomes and urinary/sexual outcomes following radical prostatectomy. Using the Retzius technique, the surgeon will remove the prostate in a way that preserves a portion of the nerves and tissue structures that are typically removed during the conventional technique. The investigators will assess recovery of urinary and sexual function of patients through questionnaires at 1 week, 1 month, 6 months, 12 months, and 24 months after surgery.
