Abstract
In a series of 560 pulmonary resections for bronchial carcinoma, unsuspected microscopic tumor was present at the bronchial resection margin in 26 patients (4.5%). Adjuvant chemotherapy or radiotherapy was given in two patients. In follow-up times ranging from 1 to 72 months (mean, 22 months), 58% of patients were alive and free of recurrent disease. Twelve patients underwent periodic surveillance bronchoscopy in an attempt to identify early local recurrence. Eighty-three percent of these patients were alive and disease-free in follow-up times from 4 to 72 months (mean, 29.7 months). Only one choscopies. It was concluded that microscopic residual resection-line tumor does not preclude prolonged survival and that no benefit from surveillance bronchoscopy could be demonstrated in this small patient sample.
