This registry will evaluate treatment selection for patients with newly diagnosed, localized prostate cancer following Prolaris testing. It will measure the proportion of men who initially select treatment with active surveillance, the time frame between active surveillance selection and any change in treatment, and clinical outcomes.
To evaluate use of the Prolaris score in treatment management decisions in an ethnically and racially diverse population of men who have been newly diagnosed with prostate cancer and who are potential candidates for active surveillance. This registry will evaluate oncologic and co-morbidity outcomes in patients who receive Prolaris testing. Additionally, the registry will measure the prevalence and distribution of pathogenic mutations in hereditary cancer risk-associated genes among men with prostate cancer who meet National Cancer Center Network (NCCN) criteria for hereditary cancer genetic testing.
The primary objective of this registry is to evaluate initial selection of active surveillance (Active Surveillance selection) versus definitive therapy (DT) among men with newly diagnosed prostate cancer who make treatment decisions with Prolaris testing, and among patient subsets defined by race/ethnicity.
The secondary objectives of the registry are to evaluate progression of from Active Surveillance to definitive therapy over time and prostate cancer-associated morbidities that affect quality of life among men with newly diagnosed prostate cancer and who undergo Prolaris testing, and among patient subsets defined by racial/ethnic background and ancestry.
Urology Practices
Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.
Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
The diagnosis was confirmed by looking at a sample under a microscope: tissue from a biopsy or surgery (histology), or cells from a fluid or needle sample (cytology).
Your pathology report is the document that shows this.
A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.
Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.
The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.
Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Recently diagnosed patients with histologically proven, localized adenocarcinoma of prostate determined via transrectal ultrasonography and biopsy of at least 10 prostate sites who have undergone Prolaris testing.
Active Surveillance (AS) selection versus Definitive Therapy (DT
The primary endpoint of the registry is Active Surveillance selection, defined as the proportion of all men who select Active Surveillance in lieu of definitive therapy following confirmatory diagnosis of localized Prostate Cancer and Prolaris testing. Active Surveillance selection is documented by the treating provider and reflects the patient-provider decision at the time to pursue Active Surveillance with no curative intent.
Time frame: 1 Year
Active Surveillance Durability; Comorbidities
Active Surveillance durability, measured as the length of time between the Active Surveillance initiation date and the first definitive therapy date. Comorbidities, including voiding problems, erectile dysfunction, bowel dysfunction, stress or urgency incontinence, depression, and anxiety, as measured by validated, standard of care quality-of-life assessments: the Expanded Prostate Cancer Index Composite Instrument (EPIC-26) and the Generalized Anxiety Disorder scale (GAD-7).
Time frame: Active Surveillance durability, date of diagnostic biopsy will be recorded as the Active Surveillance initiation date. Definitive treatments collected at baseline and annually up to 10 years Comorbidities collected annually up to 10 years.
Disease Progression
• Disease progression, measured as the proportion of men who: * Initiate and remain on Active Surveillance and subsequently experience distant metastasis or disease-specific mortality. * Initiate Active Surveillance and proceed to definitive therapy, or initially select definitive therapy, and subsequently experience biochemical recurrence (BCR), distant metastasis or disease-specific mortality. For radical prostatectomy (RP) patients, BCR is defined as PSA \>0.2 ng/mL on at least two occasions more than two weeks apart or initiation of any salvage therapy greater than or equal to 6 months after surgery. For patients treated by external beam radiation therapy (EBRT), BCR is defined by reaching a post-EBRT PSA of nadir + 2 ng/mL (Phoenix criteria) or initiation of any salvage therapy 6 months after radiation.
Time frame: Baseline to year 10
Disease reclassification
Disease reclassification, defined as a patient initially treated with Active Surveillance for whom follow-up biopsy results in reclassification of the disease into a different NCCN risk category.
Time frame: Baseline to year 10
Baseline Clinicopathologic measures
Baseline clinicopathologic measures, including pre-biopsy PSA, date of biopsy, prostate volume, biopsy findings, total number of biopsy cores, number of positive cores, clinical stage, Gleason score, NCCN risk category, and Prostate Magnetic Resonance Imaging (MRI) assessment results with Prostate Imaging Reporting and Data System (PI-RADS) score(s) when available.
Time frame: Baseline to year 10
The Proportion of Men with PrCa who:
(1) Meet NCCN hereditary high-risk criteria, (2) undergo and complete hereditary cancer genetic testing; and (3) are found to carry pathogenic variants in tested cancer-predisposition genes.
Time frame: Baseline to year 10

Started Apr 2020 (actual). Primary completion is estimated for Nov 2029, 115 months after the start.
Of 109 industry-sponsored observational studies under Prostatic Neoplasms, half reached primary completion within 45 months of starting (the median), counting those still running; a quarter within 24 and three quarters within 65. This study's planned 115 months is above that.
Counting every sponsor, half of 649 studies reached it within 60 months; a quarter within 29 and three quarters within 141.
