Summary

This study aims to evaluate the non-inferiority in recurrence-free survival and overall survival of segmentectomy compared with lobectomy in patients with lung adenocarcinoma ≤ 2 cm with micropapillary and solid subtype negative by intraoperative frozen sections.

PROCEDURE

Segmentectomy

Segmentectomy with hilar and mediastinal lymph node dissection is performed. If the tumor located at inter-segment plane and without sufficient resection margin distance, a combined segmentectomy will be performed. Systemic or selective lymph node dissection is mandatory, and nodal sampling is not allowed. At least three stations of mediastinal lymph node from 2R, 4R, 7, 8, 9 for the right side and 5, 6, 7, 8, 9 for the left side, respectively. The distance from the dissection margin to the tumor edge must be evaluated intra-operatively. If the distance is either less than the maximum tumor diameter or 20 mm, the absence of cancer cells in the resection margin must be histologically or cytologically confirmed before finishing surgery.
