Wild-type ATTR amyloidosis of the prostate: a case review
Bibliographic record
Abstract
The amyloidoses are a rare group of disorders caused by the deposition of amyloid fibrils in organ tissues. Transthyretin-mediated amyloidosis is a subcategory of amyloidosis, which can be further subdivided into hereditary transthyretin-mediated or wild-type (‘senile’) amyloidosis. Involvement of the prostate by any type of amyloidosis is rare, with only a handful of cases reported in the literature. We report here a case of a 64-year-old Caucasian man who was incidentally found to have wild-type transthyretin-mediated amyloidosis of the prostate following a radical prostatectomy for treatment of a localised, Gleason 7 (4 + 3) adenocarcinoma of the prostate. TTR subtyping was confirmed by mass spectrometry. His family history was negative for known amyloidosis, and sequencing of the entire TTR gene was negative for any mutations, so he was therefore considered to have wild-type TTR amyloidosis. He was subsequently found to have additional foci of amyloid deposition in the gastrointestinal tract. Wild-type transthyretin-mediated amyloidosis as an incidental finding in a prostate biopsy is an extremely rare finding. Treatment options for transthyretin-mediated amyloidosis are limited, and further research and treatment options are needed in this rare and difficult to manage disease. Level of evidence: The level of evidence according to the Oxford Centre of Evidence-based Medicine levels of evidence is not applicable to this case report. Given that this is a rare entity, decisions made in managing this case were based on a level of evidence of 5.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot 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.
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 teacher head, not a consensus.
