A Canadian center's experience on whole-gland salvage therapy for radio-recurrent prostate cancer with various modalities
Bibliographic record
Abstract
Salvage radical prostatectomy for localized radio-recurrent prostate cancer has historically been associated with significant morbidity. Prospectively collected data long-term data on salvage whole-gland cryoablation and, to a lesser extent, high-intensity focused ultrasound (HIFU), have shown they are viable treatment alternatives. This article chronicles the experience (cryoablation, n=187; HIFU, n=81) in a high-volume Canadian center and reviews the literature on other salvage ablative therapies. Whole-gland salvage ablation has yielded oncologic results comparable to those of salvage prostatectomy, with cancer-specific survival and metastatic-free survival of approximately 80%, and biochemical disease-free survival of 35%. Freedom from androgen deprivation therapy was 49% at 12 years. Improved ablative technologies and functional diagnostic imaging modalities have rendered focal salvage ablation feasible in selected patients. Preliminary oncologic and functional results of focal salvage ablation using several new ablative technologies are also reviewed in this article.

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.
