BackgroundThe aim of our study differs from similar studies since we compared superiority and similarity of segmentectomy performed for early-stage lung cancer over lobectomy in terms of clinical and oncological results.MethodsThe data from 294 patients who underwent anatomical resection due to primary lung cancer were retrospectively reviewed. Data from 99 patients who underwent lobectomy and segmentectomy due to early-stage lung adenocarcinoma were analyzed. Patients were divided into two groups: 84 patients undergoing lobectomy and 15 patients undergoing segmentectomy. Both groups were analyzed in terms of epidemiological, surgical and oncological results, by comparing several parameters.ResultsThe most common postoperative complication was observed in the respiratory system. In total, 25 complication (29.8%) in the lobectomy group and 3 complications (20%) in the segmentectomy group were observed related to the postoperative respiratory system (P = 0.546). There was no statistically significant difference between the two groups in terms of recurrence-metastasis during follow-up, chemotherapy-radiotherapy condition and mortality. Main discharge time and thorax drain termination time were shorter in the segmentectomy group (P = 0.011 and P = 0.033, respectively). There was no statistically significant difference between the two groups in terms of postoperative survival or disease-free time (P = 0.361 and P = 0.461, respectively).ConclusionIf there is no contraindication, segmentectomy can be considered as the surgical treatment for lung adenocarcinomas with tumor size of 2 cm or less and a minimum 1 cm clean surgical margin.© 2021 The Author(s).
