[Significance of fiberoptic bronchoscopy after pulmonary resection of lung cancer for early detection in second lung cancer].
By the end of 1988, seventy five cases after pulmonary resection for lung cancer and one case after pulmonary resection for basal cell hyperplasia were examined with fiberoptic bronchoscopy as postoperative follow up. Endobronchial tumor was detected in 14 cases. In seven cases, endobronchial tumor was located at site far from the surgical bronchial anastomosis. These tumors were suspected as second lung cancer as long as examined by fiberoptic bronchoscopy. Histological type of all of these was squamous cell carcinoma. Re-operations were performed in five cases and two of them were early lung cancer. In 6 cases (13.6%) among 44 cases examined with fiberoptic bronchoscopy after pulmonary resection for central type squamous cell carcinoma, second lung cancer was detected. In the case of central type squamous cell carcinoma, usually the tumor appears to be of same histological type and at same location. Among those cases those who smoke heavily should be separated as high risk group. If this group is followed with fiberoptic bronchoscopy or sputum cytological examination, it is more possible to detect second lung cancer at an early stage.
