Registered outcomes 5
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description | Source |
|---|---|---|---|---|
| Primary | Recurrence-free survival (RFS) according to MRD status in plasma and/or BWF ctDNA | Up to 24 months after surgery | RFS of MRD-positive versus MRD-negative participants, defined as the time from surgery to first clinical or radiologic recurrence (or death, if applicable). Estimated by the Kaplan-Meier method and compared with the log-rank test. Hazard ratio with 95% confidence interval estimated exploratorily by Cox regression. | ClinicalTrials.gov |
| Secondary | MRD detection rate in plasma ctDNA versus BWF ctDNA | 6, 12, 18 and 24 months after surgery | Proportion of MRD-positive results in paired plasma and BWF samples collected at the same time point, compared with McNemar's test. | ClinicalTrials.gov |
| Secondary | Quantitative MRD value (variant allele frequency) in plasma versus BWF | 6, 12, 18 and 24 months after surgery | ariant allele frequency of patient-specific variants in paired plasma and BWF samples, compared with the paired t-test or Wilcoxon signed-rank test. | ClinicalTrials.gov |
| Secondary | Diagnostic performance of MRD for recurrence | Up to 24 months after surgery | Sensitivity, specificity, positive predictive value, negative predictive value, and area under the ROC curve (AUC) of plasma and BWF MRD for detecting recurrence, evaluated exploratorily and compared descriptively with CT and CEA. | ClinicalTrials.gov |
| Secondary | Lead time of MRD positivity before recurrence confirmation | Up to 24 months after surgery | Interval (months) from first MRD positivity to recurrence confirmed by CT or clinical diagnosis, summarized as mean ± SD or median (IQR), range, and 95% confidence interval, and compared with CT and CEA. | ClinicalTrials.gov |
