Brief Title: Segmentectomy Versus Lobectomy for Lung Adenocarcinoma ≤ 2cm
Official Title: Comparison of Segmentectomy Versus Lobectomy for Lung Adenocarcinoma ≤ 2cm With Micropapillary and Solid Subtype Negative by Intraoperative Frozen Sections: A Prospective and Multi-center Randomized Controlled Trial Study
Study ID: NCT04937283
Brief 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.
Detailed 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 weather segmentectomy is appropriate for invasive adenocarcinoma without micropapillary patterns. This prospective and multi-center study was aimed to evaluate the non-inferiority in recurrence free survival and overall survival of segmentectomy compared with lobectomy in patients with lung adenocarcinoma (≤ 2 cm) not including micropapillary components.
