Morbidity and Mortality after Major Pulmonary Resections in Patients with Locally Advanced Stage IIIA Non-small Cell Lung Carcinoma Who Underwent Induction Therapy

BackgroundThe optimal treatment for patients with locally advanced stage IIIA non-small cell lung carcinoma (NSCLC) remains controversial, but induction therapy is increasingly used. The aim of this study was to evaluate mortality, morbidity, hospital stay and frequency of postoperative complications in stage IIIA NSCLC patients that underwent major pulmonary resections after neoadjuvant chemotherapy or chemoradiation.MethodsWe conducted a retrospective analysis of all patients who underwent major pulmonary resections after induction therapy for locally advanced NSCLC from October 2009 to February 2014. Forty-one patients were included in the study.ResultsComplete resection was achieved in 40 patients (97.5%). A complete pathologic response was seen in 10 patients (24.4%). Mean hospital stay was 17.7 days (ranged 5-129 days). Early (in-hospital) mortality occurred in 2.4% (one patient after bilobectomy), late (six months) mortality in 4.9% (two patients after right pneumonectomy and bilobectomy), and overall morbidity in 58.5% (24 patients). Postoperative complications included: bronchopleural fistula (BPF) with empyema – three patients, empyema without BPF – five patients, air leak – eight patients, atrial fibrillation – eight patients, pneumonia – eight patients, and lobar atelectasis – four patients.ConclusionFollowing neoadjuvant therapy for stage IIIA NSCLC, pneumonectomy can be performed with low early and late mortality (0% and 5.8%, respectively), bilobectomy is a high risk operation (16.7% early and 16.7% late mortality); and lobectomy a low risk operation (0% early and late mortality). The need for major pulmonary resections should not be a reason to exclude patients from a potentially curative procedure if it can be performed with acceptable morbidity and mortality rates at an experienced medical centre.
