Preoperative evaluation of patients with suspected bronchogenic carcinoma

Selection by mediastinoscopy and long-term survival in bronchial carcinoma

In order to reduce the high rate of inoperability in patients with bronchial carcinoma, mediastinoscopy was carried out as a routine preoperative selection in 874 patients during 13 years. Two hundred thirty-six patients (27%) were found to have involved lymph nodes at mediastinoscopy and were not treated surgically. Follow-up data were available on 210 of them: 165 (79%) died within a year, 16 survived for 2 years, and 4 for 5 years. Pulmonary resection was carried out in 638 patients. Five-year survival in the series was 24.5% and 10-year survival (based on 104 eligible patients), 16.3%, including the operative mortality of 5.5%. Mediastinoscopy has not improved long-term survival to any great extent. However, it has raised the rate of resectability to 97.1% and lowered the operative mortality without denying the patient a chance of cure.

The clinical assessment of selected patients with bronchogenic carcinoma

This paper describes the clinical management of patients with malignant cells in their sputum and a normal chest roentgenogram and those with asymptomatic peripheral pulmonary masses. The source of malignant cells in the sputum of patients with no roentgenographic abnormalities can be localized by tantalum bronchography and fiberoptic bronchoscopy. Peripheral pulmonary masses can be diagnosed preoperatively by needle biopsy or transbronchial fiberoptic bronchoscopy with little morbidity and no mortality. These procedures are not necessary, however, if there is firm clinical and roentgenographic evidence of malignancy. Bronchogenic carcinomas presenting as asymptomatic circumscribed peripheral pulmonary masses have a 25% incidence of occult mediastinal lymph node metastases. In view of this relatively high incidence of metastasis, we think mediastinoscopy should routinely be performed prior to thoracotomy is asymptomatic patients with a peripheral pulmonary mass and no roentgenographic evidence of mediastinal widening.
