Clinical Trial Summary

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


Clinical Trial Description

At present, the technology of intraoperative frozen section has gradually matured, which can diagnose the benign and malignant tumors and guide the resection strategy for peripheral small-sized lung adenocarcinoma. Travis et al. reported high specificity of intraoperative frozen section in the identification of micropapillary components, confirming that intraoperative frozen section may guide the selection of surgical procedures. However, there is still little evidence whether segmentectomy is appropriate for invasive adenocarcinoma without micropapillary patterns. This prospective and multi-center study was aimed to evaluate the superiority in recurrence free survival and overall survival of lobectomy compared with segmentectomy in patients with lung adenocarcinoma (≤ 2 cm) containing positive micropapillary components. ;
