Purpose: A sleeve lobectomy for lung cancer is a procedure intended both for the maintenance of lung function and for radical treatment. We investigated the clinico-pathological features and treatment responses of lung cancer patients who underwent sleeve lobectomy in our department.
Subjects: Among the 984 patients with non-small cell lung cancer who underwent resection in our department between 1994 and 2007, the subjects were 24 patients in whom a sleeve lobectomy was performed.
Results: There were 18 male and 6 female patients, with a mean age of 65 years. The histological type was diagnosed as squamous cell carcinoma in 14 patients, and adenocarcinoma in 10. Patients with either mucoepidermoid carcinoma (n=1) or carcinoid tumor (n=1) were excluded. The pathological stage was evaluated as IA, IB, II, IIIA, IIIB, and IV in 4, 1, 8, 8, 2, and 1 patient, respectively. Regarding post-operative complications, 4 patients required sputum aspiration with a bronchoscope from the 2nd to 7th post-operative day due to sputum retention. The 5-year survival rate in patients who underwent sleeve lobectomy was 70.0%. According to the pathological nodal status, the 5-year survival rates of N0, N1, and N2 were 100.0%, 87.5%, and 41.7%, respectively. The 5-year survival rates in squamous cell carcinoma and adenocarcinoma were 83.0% and 45.7%, respectively.
Conclusion: Sleeve lobectomy facilitated the maintenance of residual lung function without serious perioperative complications. This finding suggests that patients with direct tumor invasion to the bronchus might be good candidates for a sleeve lobectomy, but not those with extra-nodal invasion.

Objective: We aimed to identify the diagnostic value of next-generation sequencing (NGS) of bronchoalveolar lavage fluid (BALF) from patients with non-small-cell lung cancer (NSCLC).
Methods: Forty patients who were initially diagnosed with pulmonary nodules were enrolled. Frozen section histology was used to identify the NSCLC cell types.

Sleeve lobectomy has solidified its position as a preferred alternative to pneumonectomy due to its significant advantage in preserving lung function, whereas right lower lobe sleeve lobectomy remains relatively uncommon because of the higher technical challenge. With the development of minimally invasive technology and experience acquired over the years, robot-assisted thoracoscopic surgery (RATS) has shown progress and distinct advantages compared to the traditional thoracotomy and video-assisted thoracoscopic surgery (VATS) approach. Owing to its 3D vision, bendable wrist joints, and tremor filtration capabilities, this surgical technique exhibits great advantages in complex thoracic operations demanding for reconstructive procedures compared to traditional thoracoscopic surgery.

Background: In the treatment of central-type non-small cell lung cancer (NSCLC), sleeve lobectomy (SL) has emerged as the surgical treatment of choice over pneumonectomy (PN). This retrospective study evaluates the clinical profiles and prognostic elements impacting survival and recurrence rates in patients who underwent SL.
Methods: We retrospectively analyzed 288 patients who underwent SL from January 2010 to December 2023.

Background: To compare short-term mortality and long-term overall survival between sleeve lobectomy and pneumonectomy for centrally located non-small cell lung cancer (NSCLC).
Methods: We retrospectively reviewed patients who had been radically resected for NSCLC by sleeve lobectomy with or without pulmonary arterioplasty at our institution between 2009 and 2023. We then propensity score-matched the patients with pneumonectomy counterparts from a national registry and compared their 30- and 90-day mortality and long-term overall survival before and after matching.
