Impact of androgen deprivation therapy on depressive symptoms in men with nonmetastatic prostate cancer
Bibliographic record
Abstract
BACKGROUND: Up to 50% of prostate cancer (PC) patients receive androgen deprivation therapy (ADT), often for several years. Although depression has been reported after a diagnosis of PC, whether ADT leads to or worsens depression is not clear. METHODS: Three groups were assembled: ADT users (men initiating continuous ADT), PC controls (PC patients who were not on ADT), and healthy controls. All 3 cohorts were matched on age, education, and physical function, and none had metastases. Depression was measured at study entry and again at 3, 6, and 12 months using the 15-item Geriatric Depression Scale (GDS). Our primary outcomes were worsening depressive symptoms and incident depression (defined as a GDS score ≥5), analyzed using adjusted linear regression and logistic regression, respectively. RESULTS: Of the 257 participants (mean age, 69.1 years), baseline characteristics including GDS score and prior depression were similar across cohorts. In adjusted analyses of initially nondepressed patients, ADT use was not a significant predictor of change in GDS score at 3 months (P = .42), 6 months (P = .25), or 12 months (P = 0.19). Among ADT users, 8%-9% of participants developed incident depression compared with 0%-4% among PC controls and 4%-6% among healthy controls over 3-12 months (P>.05 at all time points). In a separate analysis of patients with depression at baseline, there was no effect of ADT on depressive symptoms at 3, 6, or 12 months (P = .11, .74, and .12, respectively). CONCLUSION: Twelve months of ADT use were not associated with worsening depressive symptoms among nondepressed or depressed patients with nonmetastatic PC.

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.
