Area of Science:

Urology
Pathology
Medical Diagnostics

Background:

Prostate biopsy is crucial for cancer treatment decisions.
Specimen collection and diagnosis are prone to human error and contamination.
Specimen provenance testing (SPT) ensures biopsy result reliability.

Purpose of the Study:

To evaluate the effectiveness of the Know Error test for prostate biopsy specimen verification.
To assess the rate of specimen contamination and its impact on diagnosis.

Main Methods:

Retrospective review of 921 prostate biopsy specimens from 445 patients over 16 months.
Utilized the Know Error test for specimen verification.
Cross-referenced Know Error results with pathology reports (Gleason Grade Groups).

Main Results:

Specimen verification rate was 92.8% with a 2.8% contamination rate.
Identified 17 patients (8 GG1, 9 GG2) with contaminated biopsy specimens.
Contamination can negatively impact patient counseling and treatment.

Conclusions:

Specimen provenance testing, like the Know Error test, is essential for accurate prostate cancer diagnosis.
Ensuring specimen integrity is critical to prevent misdiagnosis and inappropriate treatment.
SPT safeguards against errors that could lead to adverse patient outcomes.
