Prostate cancer (PCa) is the most commonly diagnosed cancer in men with an estimated 23,600 new cases in 2013 and it is the third leading cause of cancer-related death in Canadian men.

The Canadian Prostate Cancer Biomarker Network (CPCBN) is a research program directed by a group of clinicians and scientists with the ultimate goal of improving the clinical management of men with prostate cancer.

Tissue samples include:

  • Optimization Tissue MicroArrays (TMAs)
    • Tissues from prostate, breast and ovarian cancer
    • Mouse xenograft tissues obtained by injecting PC3, LNCaP, Du145 or 22RV1 cell lines in mice.
  • Validation Test Cohort TMAs
    • 250 radical prostatectomies from PCa patients.
    • Initial cohort.
  • Validation Large Cohort TMAs
    • 1250 radical prostatectomies from PCa patients.
    • Independent cohort.
  • Validation Cohort TMAs
    • Three cores of tumour tissue, two cores of normal adjacent tissue.
    • Multiple centres.
    • Treatment naïve patients.
    • Complete clinical data with follow-up.
    • Clinical data stored in Advance Tissue Management (ATiM) database.
    • Two cores of xenografts tissue obtained from PC3, LNCaP, Du145 or 22RV1 injection in mice.

CPCBN Objectives

Biomarker Core

  • Assemble tissue micro-array (TMA) based validation platforms:
    • 1500 radical prostatectomy specimens
    • 250 biopsy specimens from intermediate risk patients treated by radiotherapy
    • 250 biopsy specimens from low risk patients followed by active surveillance
  • Validate biomarkers:
    • Specific to low risk disease that will not progress (biopsy based), to safely follow them by active surveillance and avoid therapeutic complication
    • Specific to patients with a high risk of progression/recurrence to combine their initial treatment with adjuvant therapies
  • Establish a nomogram to facilitate prostate cancer patient management

Knowledge to Action Core

  • Snapshot of active surveillance uptake in Canada for the year 2010
  • Use focus groups to identify the barriers in the offer, acceptance and adherence to active surveillance in Canada
  • Organize a knowledge transfer meeting of TFRI translational projects, to tackle how to transfer scientific discovery to clinical practice as a means of improving health outcomes for patients.
