This is a single center, prospective and observational study conducted in three stages to predict the NSCLC lymph node metastasis based on ctDNA/specific methylation molecular features combined with PET-CT imaging features and intervention study.
This is a prospective study conducted in three stages. The volume of blood drawn will be 30 mL each time.
Stage 1: We will enroll 200 patients diagnosed with stage I-IIIB NSCLC who are scheduled for lobectomy and systematic lymph node dissection. The prediction of lymph node metastasis will be based on preoperative blood ctDNA mutation and methylation profiling. Specifically, during this stage, we will prospectively establish ctDNA methylation signatures specifically associated with LNMs in NSCLC. These molecular profiles will be combined with PET-CT imaging. Postoperative pathological results will serve as the reference standard for comparison.
Stage 2: A certain number (depending on the Results of Stage 1) of patients requiring invasive mediastinoscopy or EBUS-TBNA, based on the clinical guidelines, will be included for blood ctDNA mutation/methylation profile (or combined PET-CT), and the detection rate of LNMs will be assessed in patients with negative preoperative blood ctDNA mutation/methylation (or combined PET-CT). The accuracy of predicting LNMs will be compared with that of patients with negative or positive preoperative blood ctDNA mutation/methylation (or combined PET-CT).
Stage 3: For patients with negative preoperative blood negative testing (ctDNA mutation/methylation profiles alone or in combination with PET-CT), systematic lymph node sampling/dissection and no lymph node dissection will be grouped and compared. Regular follow-up is performed to investigate the impact on long-term MRD negative duration and prognosis. The primary outcomes: postoperative MRD negative duration and progression-free survival (PFS); The second outcomes: Overall survival (OS).

| Blood ctDNA + methylation + PET-CT and Postoperative pathology | Procedure | A highly sensitive tumor-naïve MRD panel of ctDNA will be employed to detect preoperative blood. Some patients will undergo methylation profiling to prospectively establish LNMs-specific ctDNA methylation signatures. |
| Measure | Description | Time Frame |
|---|---|---|
| Negative prediction value (NPV) of lymph node metastasis rates | The primary endpoint will be the negative prediction value (NPV) of LNM rates between groups using preoperative blood ctDNA/methylation alone or in combination with PET-CT. LNMs-specific ctDNA methylation signatures will be developed and the sensitivity and specificity of ctDNA mutation/methylation profiles alone or when combined with PET-CT scans for predicting LNMs will be assessed. Postoperative pathological results will serve as the reference standard for comparison. | one day for each patient |
| Disease-free survival (DFS) | DFS is defined as the time from surgical resection to tumor recurrence or death due to tumor progression. DFS will be compared between the ctDNA-positive group and the ctDNA-negative group. DFS will be assessed in stage 3. | Until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 5 years. |
| ctDNA-free interval (CFI) | CFI is defined as the duration between a patient's transition from ctDNA negative to ctDNA positive status. | Until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 5 years. |
| Measure | Description | Time Frame |
|---|---|---|
| Overall Survival (OS) | OS is defined as the time between the start of the patient's surgical resection and any documented death from any cause. OS will be compared between ctDNA-positive and ctDNA-negative groups. OS will be assessed in stage 3. | Until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 5 years |
