[Lung preserving operation for bronchogenic carcinoma--segmentectomy and bronchoplastic lobectomy]

The results of segmentectomy and bronchoplastic lobectomy for bronchogenic carcinoma were reported. Until December 1992, 920 patients underwent lung resection for primary lung cancer at our institution. Among them, 70 patients (7.6%) had segmentectomy and 149 (16.2%) had bronchoplastic lobectomy. In cases with segmentectomy, adenocarcinoma (57.1%) and Stage I disease (77.1%) were dominant, and in cases with bronchoplasty, m squamous cell carcinoma (69.8%) and Stage IIIA (45.0%) were frequent. There were no operative deaths and one hospital death (1.4%) in patients with segmentectomy, and 8 operative deaths (5.4%) and 9 hospital deaths (6.0%) in those with bronchoplasty. Five-year survival rates of the patients with segmentectomy were 49.6% in total and 64.6% in those with Stage I disease. Five-year survival rates of those with bronchoplasty were 33.9% in total, 51.1% in those with Stage I, 29.1% in those with Stage IIIA and 39.0% in those with squamous cell carcinoma. Respiratory function was well preserved in patients with segmentectomy and bronchoplastic lobectomy. Lung-preserving operations such as segmentectomy and bronchoplastic lobectomy are meaningful as a curative procedure for primary lung cancer for selected patients.
