Study Details

Study Description

Brief Summary

This is a prospective study to measure the impact on first-line therapy of genomic testing of biopsy tissue from recently diagnosed treatment-naïve patients with early stage localized prostate cancer.

Condition or Disease Intervention/Treatment Phase
  • Behavioral: Prolaris

Detailed Description

This is a prospective study to measure the impact on first-line therapy of genomic testing of biopsy tissue from recently diagnosed treatment-naïve patients with early stage localized prostate cancer. Multiple individual VAMC sites will participate in PART 1 of the study. During PART 1 of the study, a three-part questionnaire will be completed to evaluate the PRE-Prolaris test treatment plan, the POST-Prolaris test treatment plan, and the ACTUAL treatment option. Using PRE-Prolaris Test Questionnaire #1 the physician will record the recommendation for first-line therapy based on standard clinical-pathological parameters (PSA, Gleason score, clinical stage and percent positive cores). The likelihood of recommending a non-interventional therapy approach will also be recorded using a 10-point ordinal scale. A sample of the biopsy tissue will then be tested using the Prolaris® genomic test and a relative cancer aggressiveness score will be shared with the physician. After reviewing and considering the results of the genomic testing and after patient consultation, the physician will complete POST-Prolaris Questionnaire #2 documenting the planned treatment ( interventional treatment or non-interventional). Approximately 6 months from the date of the test results, ACTUAL Treatment Questionnaire #3 will be completed to document the actual treatment administered.

PART 2 of this study is a prospective evaluation of the prognostic utility of Prolaris® testing of prostate biopsy samples obtained from men who participate in PART 1of the study and who undergo radical prostatectomy or radiation therapy or who are managed with WW or AS. The central VAMC site will be responsible for PART 2; individual VAMC sites will not participate in this part of the study. Patients will be followed using medical record review every 6 months for objective progression (BCR, radiographic or radionuclide evidence of metastases or disease specific mortality) through 5 years.

Arms and Interventions

Arm Intervention/Treatment
Early Stage Prostate Cancer

Recently diagnosed treatment-naïve patients with early stage localized prostate cancer

Behavioral: Prolaris
Series of three questionnaires to capture treatment decisions based upon standard clinical-pathological information with the addition of Prolaris genomic testing result
Other Names:
  • RNA expression signature based on a set of cell cycle progression (CCP) genes
  • Outcome Measures

    Primary Outcome Measures

    1. Impact of Prolaris on the magnitude of change between Pre-Prolaris treatment selection and the actual implemented treatment [6 months]

      Comparison of percentage change from the Pre-Prolaris test treatment option (based on standard clinical pathological parameters) versus the actual treatment option implemented following results of Prolaris

    2. Prolaris prediction of biochemical or objective recurrence [5 years]

      Biochemical recurrence (defined as PSA >0.2 ng/ml or by Phoenix definition) or objective recurrences of disease by 5 years following definitive therapy with curative intent in men treatment with radical prostatectomy or radiation therapy

    Other Outcome Measures

    1. Prolaris prediction of who benefits from the addition of hormone therapy to contemporary radiation therapy [5 years]

      either biochemical or objective recurrences of disease following definitive therapy with curative intent in men treated with radiation who did or did not receive adjuvant ADT

    2. Comparison of prognostic utility of prospective Prolaris testing of prostate biopsy samples to other clinical pathological parameters with respect to disease progression [5 years]

      either biochemical or objective recurrences of disease following definitive therapy with curative intent in men treated with radical prostatectomy or radiation

    3. Association of Prolaris score with progression to active intervention when initially managed with AS or WW [5 years]

      Progression to interventional therapy in men initially managed with AS or WW

    4. Prognostic utility of Prolaris testing compared to other clinical pathological parameters with respect to disease progression in men who were Gleason score <7 on initial biopsy [5 years]

      biochemical or objective recurrence of disease in men who were Gleason score <7

    5. Impact of Prolaris on magnitude of change between pre-Prolaris treatment selection and the post-Prolaris treatment plan following consultation with the patient [3 months]

      comparison of percentage change from the pre-Prolaris treatment option versus the post-Prolaris treatment plan

    6. Impact of Prolaris on magnitude of change between physician likelihood of recommending non-interventional therapy and the likelihood following the genomic test results [3 months]

      mean change in the physician's likelihood of recommending watchful waiting or active surveillance post-genomic testing compared to pre-genomic testing
