This is a long-term prospective registry study to determine whether Prolaris testing in patients with favorable intermediate risk prostate cancer influences physician management decisions toward conservative treatment in patients with Prolaris low-risk scores without negatively impacting patient oncologic outcomes, thereby sparing low-risk patients from unnecessary treatments and associated side-effects.
This is a long-term prospective registry to evaluate the impact of Prolaris testing on therapeutic decisions in patients with newly diagnosed favorable intermediate-risk localized prostate cancer and to summarize clinical oncologic outcomes. The design of the study is non-interventional, and therefore the protocol will not require a specific treatment plan for study participants. However, in the absence of a universally accepted timeframe for repeat biopsies within existing active surveillance recommendations, study sites will be encouraged to monitor patients for disease progression as per the standard of care (e.g., current National Comprehensive Cancer Network [NCCN] guidelines) with the expectation of a repeat biopsy within 18 months of the initial biopsy.
Patients who undergo Prolaris testing will be included in the registry as well as patients who do not undergo Prolaris testing. Data collection for the first primary objective extends over a 3-year period. During this time, data is collected on the treatment initiated, any follow-up prostate biopsy performed in patients initially treated with active surveillance, definitive treatments performed (with pathology data if surgical therapy is performed), and the reasons definitive treatment was pursued, as well as data related to disease progression such as biochemical recurrence, development of prostate cancer metastases, or disease specific death.
Data collection for the second primary objective extends out to 8 years. During this time data is collected on any follow-up prostate biopsy in patients still treated with active surveillance, definitive treatments performed (with pathology data if surgical therapy is performed), and the reasons definitive treatment was pursued, as well as data related to disease progression such as biochemical recurrence, development of prostate cancer metastases, or disease specific death.
Newly diagnosed (≤ 6 months), treatment-naïve patients with favorable intermediate-risk localized prostate cancer whose initial treatment has not been decided and who are being seen at Medicare Certification and Training Registry (CTR) practices in the United States.

Patients who have undergone CCP testing and patients who have not undergone CCP testing will be considered for enrollment in the study.

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.
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.
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.
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.
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.
