BACKGROUND: For early stage non-small cell lung cancer, whether limited resection can yield comparable outcomes to those of lobectomy hasn't been established. We compared Overall survival (OS) and lung cancer-specific survival (LCSS) after segmentectomy or lobectomy in stage IA1 (≤10 mm) lung adenocarcinoma (LUAD) patients. RESEARCH DESIGN AND METHODS: We retrospectively recruited patients who'd been diagnosed with lung cancer for the first time and treated with segmentectomy or lobectomy, with or without previous other malignancy. RESULTS: 1788 patients were included. After propensity score matching: 5-year OS were 85.6% for segmentectomy and 84.7% for lobectomy (p=0.951); 5-year LCSS were 93.5% for segmentectomy; and 93.0% for lobectomy (p=0.726). Cox regression analysis revealed segmentectomy was comparable to lobectomy in OS and LCSS. Having a second lung cancer later in life was associated with a worse LCSS for lobectomy (p<0.05) rather than segmentectomy. After patients were stratified according to malignancy history, subgroup analyses showed no significant prognosis differences between two surgeries. CONCLUSIONS: For stage IA1 LUAD patients who were diagnosed with lung cancer for the first time, with or without previous other malignancy, segmentectomy yields comparable outcomes to those of lobectomy. It may provide better outcomes for patients with multiple suspicious nodules.
