Abstract:
:Seventy-eight patients with metastatic cancer to the lungs underwent flexible fiberoptic bronchoscopy for diagnosis. The patients were divided into two groups by presenting radiographic pattern as: (I) diffuse linear interstitial infiltrations (55 patients); and (II) localized or multiple nodular opacities (23 patients). The diagnosis of cancer was established by bronchoscopy in both groups of patients with approximately equal frequency. In Group I, bronchoscopic biopsy results were positive in 34 patients (62%), cytology results were positive in 30 patients (55%), and 42 patients (76%) had a positive biopsy and/or cytology result. In group II, biopsy results were positive in 14 patients (61%), cytology results were positive in 8 patients (35%), and 15 (65%) patients had a positive biopsy and/or cytology result. Patients whose chest radiograph showed atelectasis, suggesting the presence of endobronchial metastases, were excluded from the study. However, endobronchial examination unexpectedly revealed metastatic endobronchial carcinoma in 9 patients, 4 in Group I and 5 in Group II. Fiberoptic bronchoscopy is a relatively simple and direct technique for the histologic diagnosis of metastatic cancer to the lungs. Endobronchial metastases are common, even when not suspected by radiographic examination.
