Comparing Standard of Care Biopsy System to a Novel Biopsy Needle System by Computational Pathologic Analysis

Overview

Prostate biopsy is the definitive examination to establish the diagnosis of prostate cancer, but up to 40% of these biopsies overestimate or underestimate the severity of the disease. A novel biopsy needle system captures substantially more tissue than standard of care needles, but it is important to assess the retrieval of tissue for pathologic analyses. This study will compare quality and quantity of tissue retrieved by both systems. Further, tissue will be analyzed using computational pathology algorithms for atypical small acinar proliferation and Gleason scores in terms of tissue area, tissue length, and tissue tortuosity.

Prostate tissue captured in needle biopsy procedures are used to diagnose prostate cancer, but current biopsy systems (standard of care control device) have been shown to underperform when compared to a new novel needle biopsy system (test device). The objectives of the study are to (1) compare tissue quality between test and control devices; (2) compare diagnostic ambiguity between the two devices; and (3) compare tissue area, length, and tortuosity from the samples with a computational pathology algorithm. Tissue analyses will be completed by pathologists blinded to the biopsy system used.
