Abstract

fetched live from OpenAlex

Despite many large randomised trials assessing adjuvant endocrine treatment for postmenopausal breast cancer patients, the optimal endocrine strategy remains unknown. Neoadjuvant endocrine studies provide the opportunity to model an appropriate study design in a more expeditious manner. Several large adjuvant trials are exploring sequential aromatase inhibitor (AI) strategies. The present study compared the effect of two sequences of AI use – steroidal (exemestane (E)) and nonsteroidal (anastrozole (A)) – on serological and pathological biomarkers, when given in the neoadjuvant setting to patients with locally advanced breast cancer.

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.

Not 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.
