Brief Summary

Study the effect 3D printed or 3D virtual prostate models of a patient, when manipulated by surgeons during RARP, has on positive surgical margins and functional outcomes of patients. Our main hypothesis is that there is a reduction of positive resection margins and functional outcomes of patients undergoing RARP when surgeons are presented with 3D printed or 3D virtual patient-specific prostate models during surgery. Specifically, we hypothesize that the anatomical knowledge of surgeons that results from the manipulation of 3D printed/virtual models constructed from automated segmentations reduces positive resection margins and functional outcomes.

Outcome Measures

Primary Outcomes (4)

  • Automated segmentation metrics

    Automated segmentation metrics in relation to the accuracy of predicted masks of prostate gland and lesions

    Assessed after mp-MRI of patient is available and before surgery (RARP). Reported at end of study (6 months).

  • Patient recruitment rate

    Patient recruitment rate will be captured throughout the study to measure effectiveness in preparation for a follow-up randomised control trial.

    Assessed throughout the study for each patient. Reported at end of study (6 months).

  • Percentage of cases that led to successful model deployment to the theatre

    Percentage of cases that led to successful model deployment to the theatre will be captured throughout the study to measure effectiveness in preparation for a follow-up randomised control trial.

    Assessed throughout the study for each patient. Reported at end of study (6 months).

  • Positive resection margins

    Assessed after surgery and after specimen analysis. Reported at end of study (6 months).

    Duration of the study

Secondary Outcomes (8)

  • Urinary incontinence leak outcomes

    Assessed at 6 weeks and 3 months after surgery. Reported at end of study (6 months)

  • Urinary incontinence pad weights outcomes

    Assessed at 6 weeks and 3 months after surgery. Reported at end of study (6 months)

  • Urinary incontinence quality of life outcomes

    Assessed at 6 weeks and 3 months after surgery. Reported at end of study (6 months)

  • Erectile dysfunction functional outcomes

    Assessed at 6 weeks and 3 months after surgery. Reported at end of study (6 months)

  • Surgeon's perspectives

    Assessed only once after surgery and once surgeon has participated in both arms. Reported at end of study (6 months)

  • +3 more secondary outcomes

Study Arms (2)

3D Printed Models

EXPERIMENTAL

This cohort will consist of 54 prospective cases whereby patient-specific 3D printed models will be available to the surgeon during RARP for manipulation.

Device: 3D Printed Models (3D printing facilities at GSTT)

3D Virtual Models

EXPERIMENTAL

This cohort will consist of 54 prospective cases whereby 3D virtual models will be available to the surgeon during RARP for manipulation using Innersight Labs platform.

Device: 3D Virtual Models (Innersight Labs)

Interventions

3D patient-specific printed models are given to the surgeon before the start of RARP on a given patient. These 3D models are generated using automatic segmentation in MONAI followed by validation by a radiologist, and then post-processed for 3D printing.

3D Printed Models

3D patient-specific virtual models loaded into Innersight Labs platform are given to the surgeon before the start of RARP on a given patient. These 3D models are generated using automatic segmentation in MONAI followed by validation by a radiologist, and then post-processed for 3D visualisation.

Eligibility Criteria

Age18 Years+
Sexmale
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Eligible for RARP after assessment of mp-MRI during multi-disciplinary team meetings at Guy's Hospital
  • T2b-T3 prostate cancer patients
  • Gleason's score\>=3+4 .

You may not qualify if:

  • prior treatment for prostate cancer
  • patients with pre-existing urinary incontinence problems
  • patients where mp-MRI scans are not possible
  • patients participating in other studies investigating functional outcomes after surgery will be excluded. This is to avoid other studies influencing our secondary endpoints.
