Abstract

fetched live from OpenAlex

INTRODUCTION: Prostate biopsy strategies have greatly evolved over the past 2 decades. METHODS: We performed a literature review which addressed the initial and repeat biopsy schemes, pathologic risk factors for a positive repeat biopsy, and the ideal timing as well as the number of repeat biopsy sessions. RESULTS: Extended biopsy schemes (11-13 cores) should be used at initial and repeat biopsy. In the era of extended biopsy schemes, high-grade prostatic intraepithelial neoplasia no longer represents an independent predictor of prostate cancer on repeat biopsy. Conversely, the risk is appreciably increased with atypical small acinar proliferation, and its presence warrants a repeat biopsy, which may be performed as soon as the pathologic findings of the previous biopsy become available. Second and subsequent repeat biopsies carry a low detection yield. In most instances, the decision regarding the indications and the timing of a third or subsequent biopsy may be made after a 6 to 12 months interval following the repeat biopsy. CONCLUSION: Biopsy strategies and pathologic predictors of an increased risk of prostate cancer have appreciably changed over the past 2 decades.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
