Combined Segmentectomy Versus Lobectomy for Stage IA Lung Adenocarcinoma With Ground-glass Component of Prospective, Randomized, Controlled Clinical Study

Not Applicable

Active, not recruiting

• Conditions: Combined Segmentectomy; IA Lung Adenocarcinoma
• Interventions: Procedure: Patients receive subsegmentectomy

• Registration Number: NCT05983835
• Lead Sponsor: Fujian Medical University Union Hospital

Brief Summary

This project intends to include stage IA lung adenocarcinoma patients with CT imaging grboreal lesions; compare the results of lobectomy vs combined subsegmentectomy, and compare perioperative complications, differences in lung function and long-term outcomes between the two groups.
