Docetaxel plus prednisone or mitoxantrone plus prednisone for advanced prostate cancer: Updated survival of the TAX 327 study
Bibliographic record
Abstract
5005 Background: The TAX-327 study compared 3 weekly docetaxel (D3), weekly docetaxel (D1) or mitoxantrone (M), each with prednisone (P) for 1006 patients (pts) with metastatic hormone resistant prostate cancer (mHRPC). The original analysis, undertaken in August 2003 when 557 deaths had occurred, showed significantly better survival and response rates for pain, PSA and quality of life for D3 when compared with M (Tannock et al, NEJM 2004;351:1502–12). Here we present the updated survival analysis. Methods: Investigators were asked to provide date of death or last follow up for all patients alive in August 2003. Results: By December 2007 data on 276 additional deaths were obtained (total 833 deaths, see Table ). The survival benefit of D3 as compared with M has persisted with extended follow up while D1 continues to show no significant survival advantage. More patients (17.9% and 16.7%) survived =3 years in the D3 and D1 arms compared to M (13.7%). Similar trends in survival between treatment arms were seen for pts above and below 65 years of age, for those with and without pain at baseline, and for those with baseline PSA above and below median value of 115ng/ml. Conclusions: The present analysis confirms previous findings that survival is significantly longer with D3 than with M. Survival update is ongoing.

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.
