Background: Recent trials, including JCOG0802/WJOG4607L and CALGB140503, con-firmed the oncological adequacy of segmentectomy for early-stage non-small cell lung cancer (NSCLC). This shift emphasizes the preservation of pulmonary function and minimal invasiveness. Robot-assisted thoracic surgery (RATS) offers enhanced anatomi-cal precision and potentially improves segmentectomy outcomes. Methods: We reviewed the current evidence comparing sublobar resection and lobectomy for early-stage NSCLC, focusing on RATS segmentectomy. Clinical trials, perioperative and long-term outcomes, technical innovations, and patient selection criteria were analyzed. Comparative data among RATS, video-assisted thoracoscopic surgery (VATS), and open approaches were synthesized, including the emerging roles of AI and 3D imaging. Results: Segmentectomy yields survival outcomes equivalent or superior to lobectomy for stage IA peripheral NSCLC ≤2 cm, with better pulmonary function despite higher locoregional recurrence. RATS enhances visualization, dexterity, and ergonomics, thereby enabling precise dissec-tion and lymph node assessment. Compared to VATS and open surgery, RATS shows lower conversion rates, reduced pain, and comparable oncological control. Innovations, such as indocyanine green imaging, 3D modeling, and AI-guided navigation, support margin accuracy and personalized care. Conclusions: Segmentectomy has redefined the surgical standards for early-stage NSCLC. RATS maximizes the minimally invasive bene-fits by combining oncological safety and functional preservation. Its technical precision facilitates complex resections and integration with digital planning tools to advance per-sonalized thoracic surgery. RATS represents the next evolution of minimally invasive thoracic surgery, redefining the balance between oncological safety and functional preservation in early-stage NSCLC.

ABSTRACT Sulfur-containing species are of central importance for atmospheric chemistry and climate change, as they significantly influence the formation and chemical composition of submicron particulate matter (PM1). While SO2 and sulfate concentrations in Lithuania have continuously decreased since 1981 it remains unclear whether the sources and transformation mechanisms of SO42− have changed. In this study, the concentrations and sulfur isotope composition of SO2 and PM1 sulfate were measured over a two-year period to identify possible sources and formation processes of sulfur-containing species in Vilnius, Lithuania. Elevated concentrations of sulfur species were observed in autumn and winter, corresponding to lower δ34S values in winter (3.1‰ for SO2 and 0.9‰ for SO42−) and higher in summer (6.5‰ for both SO2 and SO42−). Source apportionment revealed that biomass burning was the dominant contributor to sulfur pollution in summertime (66 ± 16% in SO2 and 63 ± 17% in SO42−). In contrast, coal combustion was the primary source of SO42− during the winter of 2021–2022 (79 ± 14%), while heavy fuel oil (HFO) emissions from Vilnius thermal power station dominated both sulfate (43 ± 12%) and SO2 (40 ± 16%) fractions in 2022–2023. The airflows from the south and southwest were associated with increased SO42− concentrations and lower δ34S values. In contrast, SO2 concentrations showed only minimal variations depending on the air mass origins. These results indicate that local pollution sources are the major contributors to gaseous SO2 pollution, while SO42− pollution in Vilnius is mainly associated with regional sources. This suggests that increased SO2 emissions from HFO combustion had a significant impact on sulfate formation, predominantly through the transition metal ion oxidation pathway, in the Vilnius area.
