Prostate Cancer | Device: Decipher Device: Prolaris Device: Oncotype Dx Genomic Prostate Score (GPS) Other: Standard of care (askMUSIC score) | Not Applicable |
All patients in this study have received or will receive a score from the Michigan Urological Surgery Improvement Collaborative's Cancer of the Prostate Risk Assessment (askMUSIC) scoring system, at the time of enrollment. AskMUSIC is a risk calculator based on standard clinical and pathologic variables and is generally included as part of routine clinical care. The variables used in the risk calculator are prostate-specific antigen (PSA), Gleason score, number of positive core biopsies, number of negative core biopsies, and clinical stage.
Patients will be randomized to either an intervention arm or a control arm. In the control arm, the treating provider will review the askMUSIC score with the patient. In the intervention arm, the treating provider will review the askMUSIC and the GEC score with the patient. Biopsies obtained during the course of standard clinical care will be analyzed using one of the following GECs: Decipher, Prolaris or Oncotype Dx Genomic Prostate Score. No additional biopsies will be obtained as part of this study.
After reviewing the results, patients and their treating physicians will decide on a management strategy.
Long-term follow-up will be tracked through the Michigan Urological Surgery Improvement Collaborative (MUSIC) registry.

Arm | Intervention/treatment |
---|---|
Active Comparator: Standard of care (no pre-treatment genomics testing)
Provider will discuss askMUSIC results with patient prior to deciding on a management strategy (standard of care).
|
Other: Standard of care (askMUSIC score)
AskMUSIC is a risk calculator based on standard clinical and pathologic variables (https://ask.musicurology.com/) and is generally included as part of routine clinical care.
Other Name: askMUSIC score |
Active Comparator: Standard of care + pre-treatment genomics testing
Provider will discuss askMUSIC and Gene Expression Classifier (GEC) results with patient prior to deciding on a cancer management strategy. Patients' biopsy tissue will be analyzed using one of the following GECs: Decipher, Prolaris or Oncotype Dx.

Device: Decipher
The Decipher test (GenomeDx Biosciences) is a genomic test that will be performed on prostate biopsy tissue. Results will be provided to the patient and physician prior to making a treatment decision.
Other Name: Decipher Prostate Cancer Classifier Device: Prolaris The Prolaris test (Myriad Genetics, Inc.) is a genomic test that will be performed on prostate biopsy tissue. Results will be provided to the patient and physician prior to making a treatment decision.
Other Name: Prolaris Prostate Cancer Test Device: Oncotype Dx Genomic Prostate Score (GPS) The Oncotype Dx GPS test (Exact Sciences corp.) is a genomic test that will be performed on prostate biopsy tissue. Results will be provided to the patient and physician prior to making a treatment decision. Other: Standard of care (askMUSIC score) AskMUSIC is a risk calculator based on standard clinical and pathologic variables (https://ask.musicurology.com/) and is generally included as part of routine clinical care.
Other Name: askMUSIC score |
- Binomial proportion of men on active surveillance without treatment [ Time Frame: At 2 years ]
- Occurence of grade reclassification [ Time Frame: At 2 years ]Grade reclassification defined as an increase in grade group on surveillance biopsy (GG=1 to GG≥2 or GG=2 to GG≥3) for patients managed on active surveillance
- Rate of indolent pathology [ Time Frame: At time of prostatectomy (for patients who undergo procedure), up to 2 years ]To determine the impact of GEC testing on the rate of potentially unnecessary surgery, as defined by indolent pathology at prostatectomy (GG1 and stage pT2).
- Mean score per arm of patient reported urinary function questionnaire [ Time Frame: At 2 years ]Assessed by patient reported Expanded Prostate Cancer Index (EPIC) Urinary Incontinence Domain (UIN) questionnaire. Response options form a Likert scale, and multi-item scale scores are transformed linearly to a 0-100 scale, with higher scores representing better quality of life (QOL).
- Proportion of patients with changes from baseline in urinary function exceeding Minimal Important Differences (MID). [ Time Frame: Baseline to 12 months and 2 years ]Assessed by patient reported EPIC UIN questionnaire. For this measure, MID = 9 points.
- Mean score per arm of patient reported sexual function questionnaire [ Time Frame: At 2 years ]Assessed by patient reported Expanded Prostate Cancer Index (EPIC) sexual domain questionnaire. Response options form a Likert scale, and multi-item scale scores are transformed linearly to a 0-100 scale, with higher scores representing better QOL.
- Proportion of patients with changes from baseline in sexual function exceeding Minimal Important Differences (MID). [ Time Frame: Baseline to 12 months and 2 years ]Assessed by patient reported EPIC sexual function questionnaire. For this measure, MID = 11 points.
- Time to biochemical recurrence (BCR) [ Time Frame: From time of radical therapy until the event or the last measured follow-up, up to 2 years ]Time from treatment PSA >= 0.2 ng/mL for patients undergoing surgery (with PSA at least 5 weeks after surgery) and nadir plus 2.0 ng/mL for patients undergoing radiotherapy.
- Time to distant metastases [ Time Frame: From time of radical therapy until the event or the last measured follow-up, up to 2 years ]Assessed by CT, MRI, bone scan, and/or PET scan
- Mean score per arm of health-related quality of life (HRQOL) [ Time Frame: At 2 years ]Assessed by patient reported Expanded Prostate Cancer Index Composite short form (EPIC-26). EPIC-26 encompasses 5 domains (Urinary Incontinence, Urinary Irritative/Obstructive, Bowel, Sexual, and Hormonal). Response options for each of 26 items form a Likert scale, and multi-item scale scores are transformed linearly to a 0-100 scale, with higher scores representing better HRQOL.
- Rate of adverse pathology at prostatectomy [ Time Frame: At time of prostatectomy, up to 5 years from enrollment ]To determine the performance of GEC testing in predicting adverse pathology, defined as GG≥3 and/or ≥pT3 disease.
- Rate of biochemical recurrence [ Time Frame: Up to 5 years following treatment ]To determine the performance of GEC testing in predicting biochemical recurrence, defined as PSA >= 0.2 ng/mL for patients undergoing surgery (with PSA at least 5 weeks after surgery) and nadir plus 2.0 ng/mL for patients undergoing radiotherapy.
