OBJECTIVES Our goal was to report our midterm results using imaging-assisted modalities with robotic segmentectomies for non-small-cell lung cancer (NSCLC). METHODS This was a retrospective study of all robotic segmentectomies, with confirmed NSCLC, performed at our general and thoracic surgery unit in the Rouen University Hospital (France), from January 2012 through December 2019. Benign and metastatic lesions were excluded. Data were extracted from the EPITHOR French nationwide database. RESULTS A total of 121 robotic segmentectomies were performed for 118 patients with a median age of 65 (interquartile range: 60, 69) years. The majority had clinical stage T1aN0M0 (71.9%) or T1bN0M0 (13.2%). The mean (standard deviation) number of resected segments was 1.93 (1.09) with 80.2% imaging-assisted segmentectomies. Oriented (according to tumour location) or systematic lymphadenectomy or sampling was performed for 72.7%, 23.1% and 4.1% of patients. The postoperative course was uneventful for 94 patients (77.7%), whereas 34 complications occurred for 27 patients (22.3%), including 2 patients (1.7%) with Clavien-Dindo ≥III complications. The mean thoracic drainage duration was 4.12 days, and the median hospital stay was 4 days (interquartile range: 3, 5) after the operation. The 2-year survival rate was 93.9% (95% confidence interval: 86.4–97.8%). Excluding stage IV (n = 3) and stage 0 tumours (n = 6), the 2-year survival rate was 95.7% (95% confidence interval: 88.4–98.8%) compared to an expected survival rate of 94.0% according to stage-specific survival rates found in a large external reference cohort. CONCLUSIONS Imaging-guided robotic-assisted thoracic surgery segmentectomy seems to be useful and oncological with good midterm results, especially for patients with early-stage NSCLC.

影像辅助机器人肺段切除术治疗非小细胞肺癌的中期生存率

目标 我们的目标是报告我们使用影像辅助方式和机器人分段切除术治疗非小细胞肺癌 (NSCLC) 的中期结果。方法 这是一项回顾性研究，对 2012 年 1 月至 2019 年 12 月在法国鲁昂大学医院的普通和胸外科进行的所有机器人节段切除术和确诊的 NSCLC 进行。排除了良性和转移性病变。数据提取自 EPITHOR 法国全国数据库。结果 118 名患者中位年龄为 65（四分位距：60、69）岁，共进行了 121 次机器人节段切除术。大多数临床分期为 T1aN0M0 (71.9%) 或 T1bN0M0 (13.2%)。切除节段的平均（标准差）数为 1.93 (1.09)，其中 80.2% 的影像辅助节段切除术。对 72.7%、23.1% 和 4.1% 的患者进行定向（根据肿瘤位置）或系统性淋巴结切除术或取样。94 例（77.7%）患者术后过程顺利，27 例（22.3%）患者出现 34 例并发症，其中 2 例（1.7%）有 Clavien-Dindo ≥III 并发症。术后平均胸腔引流时间为4.12天，中位住院时间为4天（四分位距：3、5）。2 年生存率为 93.9%（95% 置信区间：86.4-97.8%）。排除 IV 期（n = 3）和 0 期肿瘤（n = 6），2 年生存率为 95.7%（95% 置信区间：88.4-98.8%），而根据分期的预期生存率为 94.0% - 在大型外部参考队列中发现的特定存活率。
