Short-term and mid-term survival in bronchial sleeve resection by robotic system versus thoracotomy for centrally located lung cancer.

Abstract

The aim of this study was to compare the short-term and mid-term results of patients with centrally located lung cancer who underwent bronchial sleeve resection by robotic system or thoracotomy. From September 2014 to September 2015, 103 patients, including 17 robotic and 86 open cases, were included in our study. All the clinicopathological data, operative details and follow-up information were investigated. There were no intraoperative deaths. The mean console time was 113.59 min. The operative time for robotic surgery (155.06 ± 44.75 min), even in our initial cases, was comparable to that for thoracotomy (150.30 ± 47.84 min, P = 0.71). The 30-day mortality rate in the robotic and thoracotomy groups was 1 (6%) patient and 2 (2%) patients, respectively, with no significant difference (P = 0.43). A total of 4 (24%) patients in the robotic group and 22 (26%) patients in the thoracotomy group experienced postoperative complications (P = 0.86). In multivariable analysis, tumour size and postoperative radiotherapy were significant predictors of relapse-free survival, whereas only the intensive care unit stay was a significant predictor of overall survival. There was no significant difference in relapse-free survival (log-rank P = 0.16) and overall survival (log-rank P = 0.59) between the 2 groups. Robotic surgery for bronchial sleeve resection is safe and feasible and has similar oncological outcomes compared with open procedures. But long-term survival still needs to be investigated.
