Optimal Extent of Pulmonary Resection in Clinical Stage IA Non-Small Cell Lung Cancer (OREX-IA)

The investigatros hypothesized that selection of surgical procedure according to the pre-defined institutional decision-making algorithm will not compromise the treatment outcomes including overall survival and disease-free survival in participants with clinical stage IA non-small cell lung cancer.

The purpose of this study is to determine the outcome of participants with clinical stage IA NSCLC treated by 3 types of surgical resection (wide wedge resection, segmentectomy, or lobectomy) according to the institutional decision-making algorithm

The investigators are planning to enroll 1,000 participants who meet the pre-defined eligibility criteria over 5 years.
