Abstract

fetched live from OpenAlex

AIMS: To investigate the impact of the 2005 International Society of Urological Pathology (ISUP) Gleason grading consensus in contemporary practice. METHODS AND RESULTS: The Gleason scores (GS) were compared in two consecutive patient cohorts with matched biopsies and prostatectomies: (i) 908 patients evaluated before the ISUP consensus (July 2000-June 2004) and (ii) 423 patients evaluated after the ISUP consensus (October 2005-June 2007). All biopsies and prostatectomies were performed and scored in one institution and were sampled and processed identically. There was a higher percentage of biopsy and prostatectomy specimens with GS > or = 7 after the ISUP consensus (GS > or = 7 on biopsy in 32% before ISUP versus 46% after ISUP; GS > or = 7 on prostatectomy in 53% before ISUP versus 68% after ISUP; P < 0.001). No significant difference in the complete and + or -1 unit Gleason agreement was found before and after the ISUP consensus. There was a trend towards better complete agreement for GS > or = 7 after the ISUP consensus. CONCLUSIONS: There was a shift towards higher GS on biopsy and prostatectomy in our practice after the ISUP consensus, although - there was no significant impact on the biopsy-prostatectomy Gleason agreement. The significance of this shift for patient management and prognosis is uncertain.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
