title: Factors affecting long-term survival of patients with bronchogenic carcinoma.
abstract: From January 1963 to December 1968, 148 patients underwent thoracotomy for bronchogenic carcinoma. In 123 patients either lobectomy or pneumonectomy was performed (resectability rate of 84 per cent). The over-all operative mortality was 3.4 per cent. Forty of the patients undergoing resection (34 per cent) are alive and free of cancer five years after surgery. Tumor size, nodal involvement, cell type, location, symptoms, and extent of surgery were studied in relation to the long-term results. Five year survival was directly related to the size of the tumor and the extent of nodal involvement. No patients with mediastinal nodal involvement or with lesions larger than 7 cm in diameter were among the long-term survivors.
