Summary
An innovative ink method for transrectal prostate biopsies matches traditional diagnostic accuracy while significantly reducing pathology costs by nearly 50%. This technique enhances efficiency in prostate cancer screening and diagnosis.
Area of Science:
- Urology
- Pathology
- Oncology
Background:
- Transrectal prostate biopsy is standard for prostate cancer screening and treatment planning.
- Increasing biopsy numbers elevate pathology laboratory costs.
- A novel ink-assisted method is compared to traditional protocols.
Purpose of the Study:
- To compare the diagnostic accuracy and cost-effectiveness of a new ink method versus the traditional approach for transrectal prostate biopsies.
- To evaluate the impact of the ink method on tumor localization and pathology expenses.
Main Methods:
- Two hundred transrectal prostate biopsy specimens were divided into two groups (100 each).
- One group underwent traditional processing; the other used an ink method with color-coded sections and a specific protocol.
- Samples were embedded and sectioned using paraffin blocks and two cassettes.
Main Results:
- No statistically significant differences in diagnostic categories were observed between the ink and non-ink methods (P < .005).
- The ink method showed a trend towards increased prostatic intraepithelial neoplasia (PIN) diagnoses, though not statistically significant.
- The ink method resulted in a substantial cost reduction of 48.86% for pathology services.
Conclusions:
- The ink method, combined with a specific histopathologic protocol, maintains diagnostic quality and tumor location accuracy comparable to the traditional method.
- This innovative approach offers a significant reduction in pathology expenses.
- The ink method presents a cost-effective alternative for transrectal prostate biopsy processing.
