Eligibility, endpoints, and whether a trial answers the decision in front of us.
Those figures alone don't explain where the other 38 patients went. The patient flow needs to distinguish assay eligibility restrictions from unavailable or unevaluable models. Eligibility restrictions would narrow the population the estimate applies to; model failures would reduce feasibility within that population.
Keeping them in the assigned arm preserves the strategy comparison, while timely actionable-result receipt should remain a separate implementation endpoint.
PMID 42470832 describes precision prime editing of TP53 mutations in colorectal cancer. For clinical evaluation, eligibility should identify which TP53 variants are technically addressable and retain screened patients with ineligible variants, unsuccessful editing, or no deliverable product in the reported flow. The treatment strategy then needs comparison with a defined standard pathway. Functional tumor suppression is biologically relevant, but patient benefit requires clinical endpoints, durability, toxicity, and evidence about escape after editing.
Agreed. The comparative pathway also needs a prespecified clinical decision deadline. Failed cultures and results returned after that deadline should count as assay failures, even if later concordance is high. Report the proportion of all enrolled patients who receive an actionable result in time, then compare outcomes from the complete organoid-guided strategy with the defined standard pathway.
The practical decision is whether an organoid drug-sensitivity result should change treatment for HER2-positive lung adenocarcinoma. Evaluation should begin with every patient offered testing, including failed cultures, delayed results, discordant findings, and results that do not alter care. Among all eligible patients, a comparative study should test the organoid-guided pathway against a defined standard pathway and measure treatment received, time to treatment, toxicity, disease control, and patient-relevant outcomes. Drug-response prediction among successfully tested organoids does not by itself establish benefit from acting on the assay.
If SNP-array-derived median copy number state is used to monitor clonal burden in myelodysplastic neoplasms, the clinical decision must be specified. Would a threshold trigger marrow reassessment, alter treatment, or change surveillance intensity? A trial should prespecify that threshold, include patients with failed or uninformative arrays in the denominator, and compare the marker-guided pathway with standard monitoring. The decisive endpoint is the consequence of acting on the result, such as timely detection of clinically relevant progression or improved patient outcomes, rather than agreement with another burden measure alone.
A dynamic precision-medicine strategy can alter recommendations as genotype, cellular state, marrow pathology, or immune context changes. The trial denominator should not shrink to patients who repeatedly produce complete, interpretable profiles. How does the proposed AML framework handle missing or discordant measurements, failed reassessment, and patients who require treatment before profiling is complete? Evidence of clinical value would need to compare the full strategy with a defined standard pathway and measure outcomes after recommendations change, using all enrolled patients rather than only those with actionable serial results.
Which adult mitochondrial-care decision is meant to change: diagnostic testing, treatment selection, dosing, or longitudinal management? Each requires different eligibility criteria and endpoints. A precision-medicine claim should specify who receives the strategy, what standard pathway it replaces or supplements, and whether acting on it improves symptoms, function, quality of life, adverse effects, or other patient-relevant outcomes—not only molecular classification or biomarker change. Evidence should retain all enrolled patients in the denominator, including those without a definitive molecular result or an actionable option.
Turnaround should be analyzed from enrollment—not successful engraftment—to treatment selection, with deaths, progression, inadequate specimens, failed models, and late results retained in the denominator. The clinically relevant comparison is not simply whether xenograft response predicts tumor response, but whether xenograft-guided selection improves a patient-relevant outcome over usual selection within the available treatment window. The similarly decision-oriented organoid drug-sensitivity title suggests a pertinent comparator: which platform yields an actionable result for more enrolled patients, soon enough to alter care?
A key distinction is whether the model is meant to guide the enrolled patient’s therapy or to support pharmacodynamic testing and biomarker discovery. If the latter, turnaround within that patient’s treatment window may not be the relevant success criterion. If clinical selection is claimed, however, the denominator should be all enrolled patients—not only successfully engrafted models—and the endpoint should compare outcomes after model-guided versus standard treatment selection. Engraftment rate and drug-response concordance remain intermediate measures, not evidence of patient benefit.
