PATTERNS OF N1 RECURRENCE IN PATIENTS WHO UNDERWENT PLASTIC PROCEDURE FOR LUNG CANCER: BRONCHIAL SLEEVE VERSUS DOUBLE SLEEVE VERSUS PULMONARY ARTERIOPLASTY

Objectives: Plastic procedure for lung cancer, such as bronchial and/or vascular sleeve, has been established as one of the options to prevent pneumonectomy. However reports on hilar recurrence remains limited, and we investigated those mode of surgery in terms of patterns of failure.

Methods: Between February 2008 and December 2015, 2060 patients with lung cancer underwent surgical resection and 113 bronchoplasty and/or 101 pulmonary arterioplasty were performed at out institute. We investigated clinicopathological features and patterns of failure by mode of surgery: 61 with only bronchoplasty (BR), 52 with bronchovascular sleeve (BV), 49 with pulmonary arterioplasty only (PA). Patterns of recurrence was especially evaluated on N1 nodal failure and compared among those procedures.

Results: Men were dominant for every group. Median age was 67 years and every group included patients who were 80 years or older. Right side was dominant for BR, and left was for BV or PA. Clinical stage I was dominant for PA. Squamous cell carcinoma was around 50%. Local failure was BR 21%, BV 23%, PA 16%. However, failure in the hilar nodes were 7%, 2%, 2% for BR, BV, PA, respectively.

Conclusions: Bronchial and/or vascular plasty were feasible for lung cancer to prevent pneumonectomy, though N1 recurrence was more frequent in patients who underwent bronchial sleeve alone.

Disclosure: No significant relationships.
