Complex video-assisted thoracoscopic surgery lobectomy for locally advanced lung cancer: a prospective feasibility...

The limitations regarding indications for video-assisted thoracoscopic surgery lobectomy requiring complex surgery remain unclear. A prospective cohort study was conducted to elucidate the safety and feasibility of complex thoracoscopic lobectomy for patients with locally advanced non-small-cell lung cancer.

We planned to enroll patients who were suspected of needing thoracoscopic lobectomy or more with complex surgery, including tracheo-bronchoplasty, pulmonary arterioplasty, and combined resection of adjacent organs. Between February 2016 and January 2019, 28 consecutive patients were prospectively enrolled.

After excluding 1 patient due to disease progression, 27 patients were included in this study. Three patients underwent thoracoscopic lobectomy without complex surgery. Of the remaining 24 patients, complex thoracoscopic lobectomy was successfully completed in 21 (88%), and the 3 conversions were due to surgery for the great vessels. All 27 patients achieved complete resection. Six patients (22%) suffered grade 2 complications, and the in-hospital, 30-day, and 90-day mortality rates were all 0%. At a median follow-up time of 900 days, the 3-year overall and disease-free survival rates were 75% and 54%, respectively.

Complex thoracoscopic lobectomy was shown to be safe and feasible in select patients with locally advanced non-small-cell lung cancer excluding invasion to the great vessels.
