Abstract
Since 1954 Transbronchial biopsy for the periferal pulmonary lesion has been successfuly applied for early diagnosis of the pulmonary neoplasm.
218 cases accumurated at the National Cancer Center Hospital for the past three years have been repoted.
Positive diagnosis were made in 83% of all cases and among those lesions of which the tumor measures less than 2cm in diameter, it was 90%.
Pathological diagnosis upon resected specimen confirmed the accuracy of the diagnosis by this method in 80%.
Anatomical exemination of the 47 resected lungs found the direct tumor invasion of the periferal bronchus in all cases. This evidence proves the feasibility of this diagnostic procedure.
There are no complication such as massive hemorrhage or dissemination of the tumor has not been encountered following this procedure.
We believe that this is the superior diagnostic method for early cytological detection of the pulmonary neoplasms.
