• 1 other identifier: CU001.B
• Study Type: observational
• Target: 25
• Locations: 1 country

Brief Summary

This clinical utility study is based on a review of real but de-identified and randomized patient cases and aims to evaluate radiation oncologist's treatment recommendations before and after reviewing the results provided by the Decipher test. The primary intent is to help guide development and design of future clinical utility studies for Decipher.

Conditions

Prostate Cancer

Outcome Measures

Primary Outcomes (1)

Study Arms (1)

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.

Other: Decipher Questionnaire

Interventions

Decipher Questionnaire OTHER

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.

Radiation Oncologists

Eligibility Criteria

• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Child (0-17), Adult (18-64), Older Adult (65+)
• Sampling Method: Non-Probability Sample

Study Population

Physicians: 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. Patients: Patients diagnosed with localized prostate cancer that received radical prostatectomy as the first line treatment. De-identified patient cases were selected from an independent clinical validation study of patients with adverse pathology features treated between 2000 and 2006. (Karnes et al., 2013)

You may qualify if:

• Patient cases eligible for this study were treated with radical prostatectomy and have one or more adverse pathological features present defined as:
• 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

You may not qualify if:

• Metastatic disease (M+) prior to surgery Received any neo-adjuvant prostate cancer treatment prior to radical prostatectomy (radiation, hormone, chemotherapy)
