[Bronchoplastic procedures for lung cancer]

Bronchoplastic procedures for patients with lung cancer are designed to achieve radical cure with preservation of functioning lung parenchyma. The operative results of 139 cases of lung cancer who underwent bronchoplasty between 1963 through 2007 were reviewed. The mean age of the patients was 62.5 years (range, 20 to 78 years). Sleeve lobectomy (SL) was performed in 119 cases, wedge lobectomy (WL) in 10 cases, sleeve segmentectomy (SS) in 5 cases, wedge segmentectomy (WS) in 2 cases, sleeve resection (SR) in 2 cases, and wedge resection (WR) in 1 case. Squamous cell carcinoma was the most frequently encountered histological type of disease (78%), followed by adenocarcinoma (12%) and other histological types (10%). The tumor was central in 125 patients (90%) and peripheral with nodal involvement in 14 patients (10%). Vascular resection and reconstruction was performed in 16 patients. Early major bronchial anastomotic complications occurred in 6 patients (4.3%). The 5-year survival rate in the patients with squamous cell carcinoma was 63.2%, and in patients with adenocarcinoma was 26.3%. SS for patients with early-stage squamous cell carcinoma of the segmental bronchus is a curative operation with preservation of the pulmonary function. Bronchoplasty without lung resection (SR, WR) is a reliable method for patients with low-grade malignant polypoid tumors arising from the bronchus. Patients with adenocarcinoma, N2 disease or major bronchial anastomotic complication show a worse prognosis.
