However, predictive risk factors for postoperative complications and early mortality remain controversial. We report our 14-year experience with this combined approach. Methods: One hundred and thirty-nine patients (100 males and 39 females) underwent induction therapy and surgery for stage IIIA and B lung cancer. The mean age was 58.4 7.7 years. We retrospectively collected demographic data, preoperative functional parameters, type of operation, associated disorders, staging, induction regimen (chemotherapy alone or associated with radiotherapy). Univariate and multivariate analyses were performed to identify predictors of postoperative complications and early mortality. Results: One hundred and nine patients received chemotherapy (mainly based on cisplatin and gemcitabine) and 30 received chemoradiotherapy (median dose 50 Gy). Complications developed in 49 patients (35%). The most frequent was persistent air leakage (23—30% of the lobectomies), followed by cardiac complications, respiratory failure, and infections. Five patients (3.5%) died in the postoperative period and four of them had received pneumonectomy (mortality for pneumonectomy: 12.5%). The statistical analysis demonstrated that only pneumonectomy was associated with an increased mortality risk with no differences between intra- and extrapericardial dissection or right and left pneumonectomy. Conclusions: Induction therapy seems to be associated with an increased incidence of air leakage; the risk of other complications is acceptable. Pneumonectomy is associated with an increased risk of mortality and should be performed in selected patients. # 2007 European Association for Cardio-Thoracic Surgery. Published by Elsevier B.V.
