Histological changes in the human prostate after radiotherapy and salvage high intensity focused ultrasound
Bibliographic record
Abstract
The histological changes (both macroscopic and microscopic) in the prostate following the combination of external beam radiotherapy and salvage high intensity focused ultrasound (HIFU) have not been previously described. This article describes the case of a 65-year-old male who presented with recurrent localized prostate cancer after undergoing external beam radiotherapy for low-risk prostate cancer. He was treated with salvage HIFU, and 4 weeks later presented with symptoms and signs consistent with a prostatorectal fistula. During a period of conservative management, his serum prostate-specific antigen levels started rising after having reached a nadir. A radical cystoprostatectomy and repair of fistula were performed after conservative management failed. Histological changes of dense fibrosis were noted in the region where the prostate should have been located. A literature review of the histological findings in the prostate after HIFU is discussed in this article, as well as the available evidence for the management of patients with local failure after the combination of external beam radiotherapy and salvage HIFU.

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.
