The neurokinin<sub>1</sub>receptor antagonist aprepitant as an antiemetic for moderately emetogenic chemotherapy
Bibliographic record
Abstract
The neurokinin-1 (NK1) receptor antagonist aprepitant has become part of standard antiemetic therapy for high-dose cisplatin. Recent results indicate that chemotherapy for breast cancer that contains an anthracycline plus cyclophosphamide is more emetogenic than has been previously realised. One large randomised trial demonstrated that aprepitant substantially reduces the risk of vomiting or retching when added to a corticosteroid and a 5-hydroxytryptamine 3 (HT3) receptor antagonist. The adverse effects of standard antiemetics and chemotherapy do not appear to be increased by the addition of this novel antiemetic agent. Aprepitant should now also be considered to be part of prophylactic antiemetic therapy for women who receive chemotherapy that contains an anthracycline and cyclophosphamide. The role of NK1 receptor antagonists in preventing emesis due to other cytotoxic agents that are deemed to be moderately emetogenic is still unclear.

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.
