Real-world clinical outcomes among patients with metastatic castration-sensitive prostate cancer initiating apalutamide
Bibliographic record
Abstract
Aim: To describe overall survival, time to castration resistance and castration resistance-free survival in patients with metastatic castration-sensitive prostate cancer (mCSPC) initiating apalutamide in a US oncology network.Patients & methods: Patients with mCSPC initiating apalutamide on or after 17 September 2019 from an electronic health record-derived deidentified database were included. Patients were followed from apalutamide initiation and were censored at the earlier of end of clinical activity or data availability (31 October 2022).Results: At 12 and 24 months, overall survival rates were 91.0 and 88.3%, rates of castration sensitivity were 85.7 and 72.1%, and castration resistance-free survival rates were 80.2 and 65.9%, respectively.Conclusion: Real-world clinical outcomes of patients with mCSPC treated with apalutamide were comparable to results from the phase III TITAN trial.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
