Brief Summary

This study seeks to determine the clinical impact of Gene Expression Classifier (GEC) testing in prostate cancer care while also developing a pragmatic approach for improved GEC clinical use and future study.

Detailed Description

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.

Primary Outcome Measures
NameTimeMethod
Binomial proportion of men on active surveillance without treatmentAt 2 years
Secondary Outcome Measures
NameTimeMethod
Mean score per arm of patient reported urinary function questionnaireAt 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).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 questionnaireAt 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.

Occurence of grade reclassificationAt 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 pathologyAt 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).

Proportion of patients with changes from baseline in sexual function exceeding Minimal Important Differences (MID).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)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 metastasesFrom 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)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 prostatectomyAt 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 recurrenceUp 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.
