Sleeve lobectomy in patients with non-small-cell lung cancer: a report from the European Society of Thoracic Surgery database 2021

OBJECTIVES For centrally located lung tumours, sleeve lobectomy is preferred over pneumectomy. We report on the surgical practices and perioperative outcomes of sleeve resections based on data from the European Society of Thoracic Surgeons database. METHODS We retrieved data of patients undergoing sleeve lobectomy or bilobectomy from 2007 to 2021. We evaluated baseline characteristics, surgical approach, neoadjuvant treatments, morbidity and postoperative outcomes of open and video-assisted thoracoscopic surgery (VATS) procedures. RESULTS In total, 1652 patients (median age: 63 years; females/males: 446/1206) underwent sleeve lobectomy (n = 1536) or bilobectomy (n = 116) by open thoracotomy (n = 1491; 90.2%) or VATS (n = 161; 9.8%) with a thoracotomy conversion rate of 21.1% (n = 34); 398 (24.1%) patients received neoadjuvant treatment. Overall morbidity and 30-day mortality were 40.6% and 2.2%, respectively. Bronchial anastomotic complications occurred in 29 patients (1.8%) with conservative treatment in 6 cases (20.7%) and operative management in 23 (79.3%). On multivariable analysis, factors related to the elevated risk of cardiopulmonary complications were body mass index < 20 [odds ratio (OR): 2.26; P < 0.001] and bilobectomy (OR : 2.28, P < 0.001). Age <60 years (OR: 0.71, P = 0.013), female sex (OR: 0.54, P < 0.001) and VATS (0.64, P < 0.001) were associated with decreased risk. Neoadjuvant treatment was not associated with increased risks of cardiopulmonary complications (OR: 1.05; P = 0.664). Compared to open thoracotomy, VATS was associated with significantly decreased overall morbidity (30.4% vs 41.7%, P = 0.006) and length of stay (median: 5 days vs 8 days; P < 0.001). CONCLUSIONS Sleeve lobectomies can be safely performed after neoadjuvant treatment. The VATS approach fosters shorter length of stay and decreased morbidity. Sleeve lobectomy is a standard surgical approach for central pulmonary tumours requiring lobectomy and necessitating a bronchoplastic procedure [1, 2].

Automated summary

This study based on the European Society of Thoracic Surgeons database provides insights into the surgical practices and perioperative outcomes of sleeve resections. The results show that sleeve lobectomy is a safe and effective surgical approach for centrally located lung tumors.
