Details and patient eligibility


Medicare is requesting outcome data on patients who received Prolaris testing and were prescribed active surveillance (AS). In order to ensure appropriate patient care, it is important to understand how this added prognostic information influences the selection and durability of AS and corresponding clinical outcomes. To address this knowledge gap, this study will evaluate how frequently men with low disease-specific mortality (DSM) risk based on Prolaris CCR score and who meet NCCN low-risk criteria initially select AS (AS selection). This study also will assess how long Prolaris-tested men who initially select AS remain on this course before proceeding to definitive treatment (AS durability), and whether AS duration impacts biochemical recurrence (BCR) and metastasis risk in these men. This retrospective, observational and multi-site study will combine patient CCR scores with longitudinal clinical data to address these questions.

Full description

This is a multicenter, retrospective, observational study in men diagnosed with localized PrCa who had Prolaris testing prior to the treatment decision. The study will collect demographic, clinical, pathologic, and Prolaris test data from medical records and Myriad's Prolaris database.

The primary objective of this study is to evaluate the rate of BCR or metastasis, whichever occurs first, among Prolaris-tested men who were at low risk of DSM (≤3.2%), who also met NCCN low-risk criteria, and who were initially treated with AS.

The secondary objectives of the study are to evaluate the frequency of AS selection among all men who had low DSM risk, as determined by Prolaris testing and AS durability among Prolaris-tested men with low DSM risk who selected and initiated this treatment.
