Punnen et al reported similar results for open retropubic radical prostatectomy (RRP) as compared to RARP in men with high-risk prostate cancer. RRP utilized as monotherapy for Gleason ≥8 in 188 men showed a disease-free survival, at 5 and 7 years, of 71% and 55% respectively. Our goal was to evaluate our experience in all patients with high-risk prostate cancer undergoing RARP at our institution. METHODS We performed a single-institution, single-surgeon review of 3,433 patients who underwent RARP from 2005 to 2014. Patients were identified who underwent RARP for high-risk disease as determined by D'Amico classification (Gleason 8- 10, stage ≥T2c, and or PSA≥20). Perioperative data was evaluated from a prospectively maintained RARP database. Treatment was considered a failure with PSA levels ≥0.2. RESULTS In total, 363 patients were identified that met high-risk classification. The median age was 63. The median BMI was 29.24. Follow-up ranged from 3 to 98 months. 1-year biochemical recurrence free survival (1-RFS) was 81.2%. 2- year biochemical recurrence free survival (2-RFS) was 63.3%. Gleason score of 8-10 was the most common pre- operative high-risk identifier (66%). Positive surgical margins occurred in 32.8% of patients. Lymph node dissection was performed on 351 patients (97%). The 12 patients that did not receive a lymph node dissection had surgery. In total, 19 patients (5.4%) were found to have positive lymph node involvement. CONCLUSIONS We present our data for the treatment of high-risk prostate cancer with RARP. Consistent with recent, but limited data, RARP appears to be an effective initial treatment for high-risk prostate cancer. Further follow-up for these patients remains necessary to help better understand long-term outcomes following RARP for high-risk prostate cancer.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
