Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
High risk patient cases were selected to reflect a range of clinicopathological variables and were further stratified based on the Decipher predicted probability of developing metastasis 5 years after RP and 3 years after BCR (as shown in the table below). High (low) Decipher (GC) risk was defined as a 5- or 3-year predicted probability of metastasis greater (less) than 6% for the adjuvant setting and greater (less) than 18% for the salvage setting.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Radiation Oncologists
Radiation oncologists targeted for recruitment into the study must meet the following criteria:
* Practicing, board-certified radiation oncologists
* Perform consultations on at least 80 patients with prostate cancer annually
Each participant is asked to complete a questionnaire to assess the impact of Decipher on physicians' treatment recommendation. All participants use the same data collection instrument. Each participant's opinion is collected based on a random selection of cases.
Decipher Questionnaire
Pathological data from 12 de-identified patient cases will be reviewed by at least 25 Radiation Oncologists before and after exposure to the Decipher test results. Given the number of patient cases, reviewed by each participant, this allows for assessment of decision making based on 300 patient case reviews at each time point, immediately following RP and at the time of PSA rise.

Decipher Questionnaire
Pathological data from 12 de-identified patient cases will be reviewed by at least 25 Radiation Oncologists before and after exposure to the Decipher test results. Given the number of patient cases, reviewed by each participant, this allows for assessment of decision making based on 300 patient case reviews at each time point, immediately following RP and at the time of PSA rise.
Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
Pathological Gleason score ≥ 8 or Gleason score 7 with primary pattern 4; Pathological stage T3a (= Extracapsular extension) or T3b (=Seminal vesicle invasion); Positive surgical margins Gleason grade upgrade from biopsy to surgery Detectable PSA, defined as failure of PSA to fall to undetectable, or PSA detectable and rising on 2 or more subsequent determinations
