Bronchoplasty for primary broncho-pulmonary tumors.

BACKGROUND Parenchyma-sparing procedures are widely used in patients with low-grade malignancies of the airway when anatomically suited lesions exist. This study was conducted to evaluate the short-term and the long-term results of bronchoplastic procedures for patients with centrally located primary bronchopulmonary tumors. METHODS Between 2000 and 2009, 36 patients with primary lung tumors required bronchoplasty were retrospectively analyzed. Preoperative assessment included computed tomography (CT) of the chest, bronchoscopy, and spirometry. Pre operative diagnosis was acheived by bronchoscopy for all patients, mediastinoscopy was done for patients with primary lung cancer. Neo adjuvant chemotherapy was given for 6 patients with non small cell lung cancer (NSCLC). RESULTS We had 15 males and 21 female, the mean age was 37 years and the mean hospital stay was 7.2 days. Operative procedures performed were:Sleeve lobectomy in 30 patients (13 right, 17 left), partial sleeve right pneumonectomy in 3 and bronchial resection with reanastomosis in 3 (2 left, 1 right). Twelve patients (33.3%) suffered post-operative problems. There was one operative related mortality. Post operative pathology revealed: 27 patients with typical carcinoid, 2 with atypical carcinoid, 4 with squamous cell carcinoma, 2 with adenocarcinoma and one with hamartoma. Pathological TNM staging revealed: 17 patients with stage IA, 11 with IB, 5 with IIA and 2 with stage IIIA. Follow-up data were available for all patients except two. Two patients died with disseminated disease 1.5 year and 2 years after surgery. The patient with hamartoma developed local recurrence 5 years later and re-excision was done. One patient with lung cancer developed bone metastases and was alive with disease, while the remaining 30 patients were alive and disease free. The overall 5 years survival was 83.3%. CONCLUSION Bronchoplastic resections achieve local control and long-term survival comparable to the standard resections in patients with carcinoid tumor and NSCLC in anatomically suited lesions.
