Abstract

fetched live from OpenAlex

Canada’s Drug Agency (CDA-AMC) recommends that Keytruda be reimbursed by public drug plans for the treatment of adult and pediatric patients with unresectable or metastatic microsatellite instability-high (MSI-H) or mismatch repair deficient (dMMR) solid tumours, as determined by a validated test, that have progressed following prior treatment and who have no satisfactory alternative treatment options, if certain conditions are met. Keytruda should only be covered to treat patients aged 6 months and older who have solid tumours with MSI-H and/or dMMR mutations that cannot be removed by surgery, or whose tumours have spread to other parts of the body; who have not responded to previous therapy and have no other treatment options available; and who are in relatively good health. Keytruda should only be reimbursed if it is prescribed by clinicians with expertise in treating advanced cancer and the cost of Keytruda is reduced. It should not be given in combination with other anticancer drugs, as well as in patients who have a history of treatment with an anti–PD-1, anti–PD-L1, or anti–PD-L2 drug.

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.
