ABSTRACT
In a retrospective study, the influence of the way bronchial carcinoma was detected was evaluated with respect to the possibility of surgery and to survival rates. From the 324 patients detected through mass screening (category I) 69.8% were suitable for surgery, whereas only 41.4% of the 736 patients detected because of pulmonary symptoms (category II) were deemed surgery-eligible. In category I, the type of surgical interventions were 65% (bi)lobectomy and 22.4% pneumonectomy. In category II, these figures were 23.4% and 53.6%, respectively. During the surgery, 10.6% turned out to be unresectable in category I, whereas 22.0% were in category II. There was also a marked difference in survival after 5 and 10 years. For category I, the 5-year survival rate was 23.4%, the 10-year survival 10.9%. In category II, these figures were 8.6% and 4.2%, respectively. The 5-year survival rate of all nonsurgically treated patients was 1% regardless of the method of diagnosis.
