Adaptive follow-up for early-stage NSCLC patients with no detectable MRD after surgery

Official title: A Prospective Multicenter Randomized Controlled Study of Adaptive Therapy in Resected Stage ⅠA2-Ⅱ NSCLC Patients With Undetectable MRD

Run by Peking University Cancer Hospital & Institute · NCT06924710 · Data updated 2026-11-12

This trial will test whether people with resected early-stage NSCLC who have two post-surgery ctDNA tests showing no detectable MRD can safely skip standard adjuvant therapy and be closely monitored instead.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are people with completely resected stage IA2–II NSCLC, ECOG performance status 0–1, anticipated survival ≥24 months, two consecutive undetectable post-surgery MRD (ctDNA) tests, and willingness to attend MRD monitoring every 3 months for two years.

Probably not a fit

Patients with detectable MRD after surgery, prior radiotherapy or chemotherapy, a recent other malignancy, or unstable systemic disease are unlikely to benefit from this MRD-guided omission approach.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a prospective, multicenter, randomized controlled trial enrolling patients with completely resected stage IA2–II non–small cell lung cancer who have two consecutive undetectable circulating tumor DNA (ctDNA) MRD tests after surgery (first at 3–7 days, second at 1 month). Eligible patients are randomized to receive conventional adjuvant therapy or an adaptive approach that omits immediate adjuvant treatment and relies on close MRD and imaging surveillance every 3 months for two years. Patients in the adaptive arm will start treatment if MRD becomes detectable or imaging demonstrates recurrence. The trial will compare recurrence and survival outcomes between the two groups to determine whether MRD-guided omission of adjuvant therapy is safe.

Why it matters

Potential benefit: If successful, some patients could avoid adjuvant chemotherapy or radiation and their side effects without increasing the risk of cancer recurrence.

How similar studies have gone: Previous research shows ctDNA-based MRD predicts recurrence risk in NSCLC, but using MRD to safely omit adjuvant therapy is still relatively unproven and remains under active study.
