The clinical value of bronchoscopic findings as a prognostic factor has been studied in 136 cases with an inoperable adenocarcinoma of the lung. The survival time in 107 cases with pathological bronchoscopic findings was significantly shorter than in 29 cases without pathological bronchoscopic findings. In the three subtypes of bronchoscopic findings, classified according to the tumor proliferation pattern, i.e. polypoid type, submucosal type and exposing type, the exposing type proved to have the worst prognosis. In addition, our study suggests that the level of infiltrated bronchus is related to the survival time. The more central the tumor infiltration, the worse the prognosis.
