• With the remarkable progress and development of the diagnostic techniques of lung cancer, numerous studies and researches have been achieved in this field in recent times.Of those technicalities, major methods which have been in wide parctice include three examinations, chest X-ray, bronchoscopic examination and cytology.In the advancement of those techniques these have been made use of in the manner in which they conpensate their shortcomings and make the most of their strong points, mutually towards perfection step by step.It is in the fields of bronchoscopic examination that has recently marked a definitely specific development among the above three techniques.<BR>The newly developed apparatus, flexible bronchofiberscope, brought about four advantages which lacked in the traditional rigid bronchoscope: the pronounced expansion of visualized field in the bronchus, the maximum abatement of discomfort on the patient all through the examination, an expanded possibility of cytology under direct vision, and the diffusion of bronchoscopic examination.To go a little further, the extension of the visualization in particular has brought forth a striking increase in the rate of lung cancer findings: newly designed biopsy attachments to the bronchofiberscope for cytology, completely unlike the traditional examination, have made histodiagnosis possible in the remote lesions located in the hitherto impossible peripheral bronchi;the biopsied material obtained by abration under direct vision and X-ray TV system is of fresh cells entirely different from those desquamated and degenerate cells obtained from the sputum which used to be the only basis for the traditional cytodiagnosis.It had been considered to be re-examined by comparing fresh cells with degenerate cells.
