Abstract
The last few years have seen an increase in the number of randomized controlled trials (RCTs) of new agents in metastatic solid tumors using progression-free survival (PFS) as the primary end point. Some trials showing improvement in PFS, without a correspondingincreaseinoverallsurvival(OS),haveledtoapprovalofnew drugs and/or changes in standard of care. This suggests a growing belief in the oncology community that delaying progression in metastaticdiseaseisaworthygoal,evenifOSisnotimproved.Butisanew treatment that improves PFS really an advance for patients? Or is it only lowering the bar to declare active some of our much-heralded new molecular targeted therapies? We believe that as a community, this trend requires discussion and debate.

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 it
