Wait times in prostate cancer diagnosis and radiation treatment
Bibliographic record
Abstract
Introduction: Wait times for cancer diagnosis and treatment area significant concern for Canadians. Men with prostate cancerexperience longer waiting times for diagnosis and treatment thanthose observed for other cancers. Longer waits are associated withboth patient and family psychosocial distress and may be associatedwith worse prognosis.Methods: Men referred for treatment of prostate cancer at a singleCanadian cancer centre were interviewed. The intervals from suspicionto definitive therapy were calculated, factors associated withdelays along this pathway were identified, and common causes ofdelay identified by patients were described.Results: A total of 41 consecutive patients participated. The medianinterval from suspicion to the first fraction of radiotherapy forall patients was 247 days (interquartile range [IQR] 168-367 d).The median diagnostic interval was 53 days (IQR 28-166 d). Themedian treatment interval was 127 days (IQR 100-180 d). Patientsunder 70 years old and patients with

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.
