Treatment of lower urinary tract symptoms suggestive of benign prostatic hyperplasia in relation to the patient's risk profile for progression
Bibliographic record
Abstract
Lower urinary tract symptoms suggestive of benign prostatic hyperplasia (LUTS/BPH) is a slowly progressing disease, with some patients progressing more rapidly than others. In 80% of patients who progress this is caused by the worsening of symptoms. The physician can predict the risk of progression from the patient's clinical profile; increased symptom severity, a poor maximum urinary flow rate (Qmax), and a high postvoid residual urine volume (PVR), are major risk factors for overall clinical progression of LUTS/BPH. A large baseline prostate volume and a high serum prostate-specific antigen (PSA) level are the predominant risk factors for developing acute urinary retention. After predicting risk, the most appropriate treatment should be established by balancing the benefits of treatment against the possible risks and bother resulting from adverse events. From the Medical Therapy Of Prostatic Symptoms study it can be concluded that monotherapy with an alpha1-adrenoceptor (AR) antagonist is an appropriate treatment for many patients with LUTS/BPH. However, for those at high risk of progression (those with a large prostate volume and high PSA level), it appears more appropriate to add a 5alpha-reductase inhibitor to the alpha1-AR antagonist to obtain maximum relief of symptoms, and ideally to halt the progression of the disease. This was confirmed by the RAND Appropriateness Method study, in which 12 urologists determined the most appropriate treatment for patients with LUTS/BPH based on their clinical profile, combination of clinical variables and/or risk factors. This study also indicates that patients at very high risk of progression, with severe obstruction (poor Qmax and high PVR), are potential candidates for immediate surgery.

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.
