Objective
The feasibility of multimodality therapy in patients with node-positive non-small cell lung cancer (NSCLC) requiring pneumonectomy and the role of pneumonectomy in N2 disease remain controversial. This study evaluated outcomes in patients with node-positive NSCLC undergoing pneumonectomy in a community hospital.
Methods
Perioperative and long-term outcomes of 37 patients with node-positive (pN1–2) NSCLC undergoing pneumonectomy from September 1994 to April 2010 as a clinical practice were retrospectively analyzed.
Results
Twenty patients received induction therapy, and 17 received preoperative chemoradiation (30–40 Gy). Fifteen patients and 22 patients underwent right and left pneumonectomy, respectively. A postoperative complication occurred in 8 patients. In-hospital mortality occurred in 1 patient. Induction therapy did not increase the operative risk including operative time, blood loss and postoperative complications. Nineteen patients were given a diagnosis of pN2. Although 7 bulky N2 patients and 10 multi-station N2 patients were included, 5-year overall survival was 34.3 % in pN1 and 28.0 % in pN2 (p = 0.998), respectively. Twenty-three patients received additional postoperative therapy. Five patients died within 3 months postoperatively due to distant metastases. Induction therapy and laterality did not influence survival. Extended resection, such as vagus nerve or chest wall resection, predicted an unfavorable outcome in multivariate analysis (Hazard ratio 2.81, p = 0.032).
Conclusions
The safety and acceptable long-term outcome of pneumonectomy as a general clinical practice were shown for both pN1 and pN2 patients with various preoperative or postoperative therapies. Extended resection due to the extrapleural or extranodal involvement of tumor was an unfavorable prognostic factor.
