A Prospective Study Investigating the Relationship Between Minimal Residual Disease Detection, Monitoring Frequency, and Prognosis in Non-small Cell Lung Cancer Patients Eligible for Curative Treatment.

Plain-language summary

Adding immune checkpoint inhibitors or molecularly targeted drugs as adjuvant therapy to curative treatments-such as surgery or chemoradiotherapy-for stage I-III non-small cell lung cancer (NSCLC) has been established as a standard of care and has improved treatment outcomes. However, there is currently no adequate method to determine which patients should receive these adjuvant therapies. Identifying those with a good prognosis without adjuvant therapy could reduce the risk of adverse events, lessen the burden of clinic visits, and reduce healthcare costs. Among various approaches, ctDNA-based MRD (minimal residual disease) analysis is highly anticipated and has already been introduced into clinical practice for hematologic malignancies. However, solid tumors' development as a companion diagnostic has been limited, and regulatory approval is mainly being considered based on performance evaluation data. In this study, we will conduct a performance evaluation of MRD analysis using Signatera™ in patients with stage I-III NSCLC while also collecting other prognostic factors based on clinicopathological information and survival data.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.

2-year PFS

Timeframe: Analyses are planned to be performed 4.5 years after the start of the study.
