Summary

This is a single-center, prospective, single-arm, open-label clinical trial evaluating the efficacy and safety of septum-guided segmentectomy in patients with 2-3 cm clinical stage IA3 peripheral non-small cell lung cancer (NSCLC) with a consolidation-to-tumor ratio (CTR) greater than 0.5 and up to 1.0. All eligible participants will undergo planned septum-guided anatomical segmentectomy or combined segmentectomy after intraoperative frozen-section confirmation of node-negative (N0) lymph node status. The primary endpoint is 3-year recurrence-free survival (RFS).

PROCEDURE

septum-guided anatomical segmentectomy

septum-guided anatomical segmentectomy or combined segmentectomy performed for eligible peripheral clinical stage IA3 non-small cell lung cancer. The intersegmental vein and intersegmental septal membrane are used as anatomical landmarks to define the intersegmental plane. Intraoperative lymph node frozen-section biopsy must confirm node-negative (N0) status before segmentectomy proceeds; positive nodal disease leads to lobectomy plus systematic lymph node dissection as standard treatment.
